+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+* Icinga 2 with its [Icinga DB feature](https://icinga.com/docs/icinga-2/latest/doc/14-features/#icinga-db) enabled,
+  responsible for publishing the data to the Redis server, i.e. configuration and its runtime updates, check results,
+  state changes, downtimes, acknowledgements, notifications, and other events such as flapping
+* And Icinga Web with the
+  [Icinga DB Web](https://icinga.com/docs/icinga-db-web) module enabled,
+  which connects to both Redis and the database to display and work with the most up-to-date data

+[![codecov](https://codecov.io/gh/VividCortex/ewma/branch/master/graph/badge.svg)](https://codecov.io/gh/VividCortex/ewma)
+
+This repo provides Exponentially Weighted Moving Average algorithms, or EWMAs for short, [based on our
+Quantifying Abnormal Behavior talk](https://vividcortex.com/blog/2013/07/23/a-fast-go-library-for-exponential-moving-averages/).
+
+### Exponentially Weighted Moving Average
+
+An exponentially weighted moving average is a way to continuously compute a type of
+average for a series of numbers, as the numbers arrive. After a value in the series is
+added to the average, its weight in the average decreases exponentially over time. This
+biases the average towards more recent data. EWMAs are useful for several reasons, chiefly
+their inexpensive computational and memory cost, as well as the fact that they represent
+the recent central tendency of the series of values.
+
+The EWMA algorithm requires a decay factor, alpha. The larger the alpha, the more the average
+is biased towards recent history. The alpha must be between 0 and 1, and is typically
+a fairly small number, such as 0.04. We will discuss the choice of alpha later.
+
+The algorithm works thus, in pseudocode:
+
+1. Multiply the next number in the series by alpha.
+2. Multiply the current value of the average by 1 minus alpha.
+3. Add the result of steps 1 and 2, and store it as the new current value of the average.
+4. Repeat for each number in the series.
+
+There are special-case behaviors for how to initialize the current value, and these vary
+between implementations. One approach is to start with the first value in the series;
+another is to average the first 10 or so values in the series using an arithmetic average,
+and then begin the incremental updating of the average. Each method has pros and cons.
+
+It may help to look at it pictorially. Suppose the series has five numbers, and we choose
+alpha to be 0.50 for simplicity. Here's the series, with numbers in the neighborhood of 300.
+
+![Data Series](https://user-images.githubusercontent.com/279875/28242350-463289a2-6977-11e7-88ca-fd778ccef1f0.png)
+
+Now let's take the moving average of those numbers. First we set the average to the value
+of the first number.
+
+![EWMA Step 1](https://user-images.githubusercontent.com/279875/28242353-464c96bc-6977-11e7-9981-dc4e0789c7ba.png)
+
+Next we multiply the next number by alpha, multiply the current value by 1-alpha, and add
+them to generate a new value.
+
+![EWMA Step 2](https://user-images.githubusercontent.com/279875/28242351-464abefa-6977-11e7-95d0-43900f29bef2.png)
+
+This continues until we are done.
+
+![EWMA Step N](https://user-images.githubusercontent.com/279875/28242352-464c58f0-6977-11e7-8cd0-e01e4efaac7f.png)
+
+Notice how each of the values in the series decays by half each time a new value
+is added, and the top of the bars in the lower portion of the image represents the
+size of the moving average. It is a smoothed, or low-pass, average of the original
+series.
+
+For further reading, see [Exponentially weighted moving average](http://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average) on wikipedia.
+
+### Choosing Alpha
+
+Consider a fixed-size sliding-window moving average (not an exponentially weighted moving average)
+that averages over the previous N samples. What is the average age of each sample? It is N/2.
+
+Now suppose that you wish to construct a EWMA whose samples have the same average age. The formula
+to compute the alpha required for this is: alpha = 2/(N+1). Proof is in the book
+"Production and Operations Analysis" by Steven Nahmias.
+
+So, for example, if you have a time-series with samples once per second, and you want to get the
+moving average over the previous minute, you should use an alpha of .032786885. This, by the way,
+is the constant alpha used for this repository's SimpleEWMA.
+
+### Implementations
+
+This repository contains two implementations of the EWMA algorithm, with different properties.
+
+The implementations all conform to the MovingAverage interface, and the constructor returns
+that type.
+
+Current implementations assume an implicit time interval of 1.0 between every sample added.
+That is, the passage of time is treated as though it's the same as the arrival of samples.
+If you need time-based decay when samples are not arriving precisely at set intervals, then
+this package will not support your needs at present.
+
+#### SimpleEWMA
+
+A SimpleEWMA is designed for low CPU and memory consumption. It **will** have different behavior than the VariableEWMA
+for multiple reasons. It has no warm-up period and it uses a constant
+decay.  These properties let it use less memory.  It will also behave
+differently when it's equal to zero, which is assumed to mean
+uninitialized, so if a value is likely to actually become zero over time,
+then any non-zero value will cause a sharp jump instead of a small change.
+
+#### VariableEWMA
+
+Unlike SimpleEWMA, this supports a custom age which must be stored, and thus uses more memory.
+It also has a "warmup" time when you start adding values to it. It will report a value of 0.0
+until you have added the required number of samples to it. It uses some memory to store the
+number of samples added to it. As a result it uses a little over twice the memory of SimpleEWMA.
+
+## Usage
+
+### API Documentation
+
+View the GoDoc generated documentation [here](http://godoc.org/github.com/VividCortex/ewma).
+
+```go
+package main
+
+import "github.com/VividCortex/ewma"
+
+func main() {
+	samples := [100]float64{
+		4599, 5711, 4746, 4621, 5037, 4218, 4925, 4281, 5207, 5203, 5594, 5149,
+	}
+
+	e := ewma.NewMovingAverage()  //=> Returns a SimpleEWMA if called without params
+	a := ewma.NewMovingAverage(5) //=> returns a VariableEWMA with a decay of 2 / (5 + 1)
+
+	for _, f := range samples {
+		e.Add(f)
+		a.Add(f)
+	}
+
+	e.Value() //=> 13.577404704631077
+	a.Value() //=> 1.5806140565521463e-12
+}

+Strip ANSI
+==========
+
+This Go package removes ANSI escape codes from strings.
+
+Ideally, we would prevent these from appearing in any text we want to process.
+However, sometimes this can't be helped, and we need to be able to deal with that noise.
+This will use a regexp to remove those unwanted escape codes.
+
+
+## Install
+
+```sh
+$ go get -u github.com/acarl005/stripansi
+```
+
+## Usage
+
+```go
+import (
+	"fmt"
+	"github.com/acarl005/stripansi"
+)
+
+func main() {
+	msg := "\x1b[38;5;140m foo\x1b[0m bar"
+	cleanMsg := stripansi.Strip(msg)
+	fmt.Println(cleanMsg) // " foo bar"
+}
+```

+# xxhash
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/cespare/xxhash/v2.svg)](https://pkg.go.dev/github.com/cespare/xxhash/v2)
+[![Test](https://github.com/cespare/xxhash/actions/workflows/test.yml/badge.svg)](https://github.com/cespare/xxhash/actions/workflows/test.yml)
+
+xxhash is a Go implementation of the 64-bit
+[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
+high-quality hashing algorithm that is much faster than anything in the Go
+standard library.
+
+This package provides a straightforward API:
+
+```
+func Sum64(b []byte) uint64
+func Sum64String(s string) uint64
+type Digest struct{ ... }
+    func New() *Digest
+```
+
+The `Digest` type implements hash.Hash64. Its key methods are:
+
+```
+func (*Digest) Write([]byte) (int, error)
+func (*Digest) WriteString(string) (int, error)
+func (*Digest) Sum64() uint64
+```
+
+This implementation provides a fast pure-Go implementation and an even faster
+assembly implementation for amd64.
+
+## Compatibility
+
+This package is in a module and the latest code is in version 2 of the module.
+You need a version of Go with at least "minimal module compatibility" to use
+github.com/cespare/xxhash/v2:
+
+* 1.9.7+ for Go 1.9
+* 1.10.3+ for Go 1.10
+* Go 1.11 or later
+
+I recommend using the latest release of Go.
+
+## Benchmarks
+
+Here are some quick benchmarks comparing the pure-Go and assembly
+implementations of Sum64.
+
+| input size | purego | asm |
+| --- | --- | --- |
+| 5 B   |  979.66 MB/s |  1291.17 MB/s  |
+| 100 B | 7475.26 MB/s | 7973.40 MB/s  |
+| 4 KB  | 17573.46 MB/s | 17602.65 MB/s |
+| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
+
+These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
+the following commands under Go 1.11.2:
+
+```
+$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
+$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
+```

+Initialize structs with default values
+
+- Supports almost all kind of types
+  - Scalar types
+    - `int/8/16/32/64`, `uint/8/16/32/64`, `float32/64`
+    - `uintptr`, `bool`, `string`
+  - Complex types
+    - `map`, `slice`, `struct`
+  - Aliased types
+    - `time.Duration`
+    - e.g., `type Enum string`
+  - Pointer types
+    - e.g., `*SampleStruct`, `*int`
+- Recursively initializes fields in a struct
+- Dynamically sets default values by [`defaults.Setter`](./setter.go) interface
+- Preserves non-initial values from being reset with a default value
+
+

+# color [![](https://github.com/fatih/color/workflows/build/badge.svg)](https://github.com/fatih/color/actions) [![PkgGoDev](https://pkg.go.dev/badge/github.com/fatih/color)](https://pkg.go.dev/github.com/fatih/color)
+
+Color lets you use colorized outputs in terms of [ANSI Escape
+Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
+has support for Windows too! The API can be used in several ways, pick one that
+suits you.
+
+![Color](https://user-images.githubusercontent.com/438920/96832689-03b3e000-13f4-11eb-9803-46f4c4de3406.jpg)
+
+
+## Install
+
+```bash
+go get github.com/fatih/color
+```
+
+## Examples
+
+### Standard colors
+
+```go
+// Print with default helper functions
+color.Cyan("Prints text in cyan.")
+
+// A newline will be appended automatically
+color.Blue("Prints %s in blue.", "text")
+
+// These are using the default foreground colors
+color.Red("We have red")
+color.Magenta("And many others ..")
+
+```
+
+### Mix and reuse colors
+
+```go
+// Create a new color object
+c := color.New(color.FgCyan).Add(color.Underline)
+c.Println("Prints cyan text with an underline.")
+
+// Or just add them to New()
+d := color.New(color.FgCyan, color.Bold)
+d.Printf("This prints bold cyan %s\n", "too!.")
+
+// Mix up foreground and background colors, create new mixes!
+red := color.New(color.FgRed)
+
+boldRed := red.Add(color.Bold)
+boldRed.Println("This will print text in bold red.")
+
+whiteBackground := red.Add(color.BgWhite)
+whiteBackground.Println("Red text with white background.")
+```
+
+### Use your own output (io.Writer)
+
+```go
+// Use your own io.Writer output
+color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+blue := color.New(color.FgBlue)
+blue.Fprint(writer, "This will print text in blue.")
+```
+
+### Custom print functions (PrintFunc)
+
+```go
+// Create a custom print function for convenience
+red := color.New(color.FgRed).PrintfFunc()
+red("Warning")
+red("Error: %s", err)
+
+// Mix up multiple attributes
+notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+notice("Don't forget this...")
+```
+
+### Custom fprint functions (FprintFunc)
+
+```go
+blue := color.New(color.FgBlue).FprintfFunc()
+blue(myWriter, "important notice: %s", stars)
+
+// Mix up with multiple attributes
+success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+success(myWriter, "Don't forget this...")
+```
+
+### Insert into noncolor strings (SprintFunc)
+
+```go
+// Create SprintXxx functions to mix strings with other non-colorized strings:
+yellow := color.New(color.FgYellow).SprintFunc()
+red := color.New(color.FgRed).SprintFunc()
+fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
+fmt.Printf("This %s rocks!\n", info("package"))
+
+// Use helper functions
+fmt.Println("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
+
+// Windows supported too! Just don't forget to change the output to color.Output
+fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+```
+
+### Plug into existing code
+
+```go
+// Use handy standard colors
+color.Set(color.FgYellow)
+
+fmt.Println("Existing text will now be in yellow")
+fmt.Printf("This one %s\n", "too")
+
+color.Unset() // Don't forget to unset
+
+// You can mix up parameters
+color.Set(color.FgMagenta, color.Bold)
+defer color.Unset() // Use it in your function
+
+fmt.Println("All text will now be bold magenta.")
+```
+
+### Disable/Enable color
+ 
+There might be a case where you want to explicitly disable/enable color output. the 
+`go-isatty` package will automatically disable color output for non-tty output streams 
+(for example if the output were piped directly to `less`).
+
+The `color` package also disables color output if the [`NO_COLOR`](https://no-color.org) environment
+variable is set (regardless of its value).
+
+`Color` has support to disable/enable colors programatically both globally and
+for single color definitions. For example suppose you have a CLI app and a
+`--no-color` bool flag. You can easily disable the color output with:
+
+```go
+var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+if *flagNoColor {
+	color.NoColor = true // disables colorized output
+}
+```
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+```go
+c := color.New(color.FgCyan)
+c.Println("Prints cyan text")
+
+c.DisableColor()
+c.Println("This is printed without any color")
+
+c.EnableColor()
+c.Println("This prints again cyan...")
+```
+
+## GitHub Actions
+
+To output color in GitHub Actions (or other CI systems that support ANSI colors), make sure to set `color.NoColor = false` so that it bypasses the check for non-tty output streams. 
+

+/*
+Package color is an ANSI color package to output colorized or SGR defined
+output to the standard output. The API can be used in several way, pick one
+that suits you.
+
+Use simple and default helper functions with predefined foreground colors:
+
+    color.Cyan("Prints text in cyan.")
+
+    // a newline will be appended automatically
+    color.Blue("Prints %s in blue.", "text")
+
+    // More default foreground colors..
+    color.Red("We have red")
+    color.Yellow("Yellow color too!")
+    color.Magenta("And many others ..")
+
+    // Hi-intensity colors
+    color.HiGreen("Bright green color.")
+    color.HiBlack("Bright black means gray..")
+    color.HiWhite("Shiny white color!")
+
+However there are times where custom color mixes are required. Below are some
+examples to create custom color objects and use the print functions of each
+separate color object.
+
+    // Create a new color object
+    c := color.New(color.FgCyan).Add(color.Underline)
+    c.Println("Prints cyan text with an underline.")
+
+    // Or just add them to New()
+    d := color.New(color.FgCyan, color.Bold)
+    d.Printf("This prints bold cyan %s\n", "too!.")
+
+
+    // Mix up foreground and background colors, create new mixes!
+    red := color.New(color.FgRed)
+
+    boldRed := red.Add(color.Bold)
+    boldRed.Println("This will print text in bold red.")
+
+    whiteBackground := red.Add(color.BgWhite)
+    whiteBackground.Println("Red text with White background.")
+
+    // Use your own io.Writer output
+    color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+    blue := color.New(color.FgBlue)
+    blue.Fprint(myWriter, "This will print text in blue.")
+
+You can create PrintXxx functions to simplify even more:
+
+    // Create a custom print function for convenient
+    red := color.New(color.FgRed).PrintfFunc()
+    red("warning")
+    red("error: %s", err)
+
+    // Mix up multiple attributes
+    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+    notice("don't forget this...")
+
+You can also FprintXxx functions to pass your own io.Writer:
+
+    blue := color.New(FgBlue).FprintfFunc()
+    blue(myWriter, "important notice: %s", stars)
+
+    // Mix up with multiple attributes
+    success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+    success(myWriter, don't forget this...")
+
+
+Or create SprintXxx functions to mix strings with other non-colorized strings:
+
+    yellow := New(FgYellow).SprintFunc()
+    red := New(FgRed).SprintFunc()
+
+    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Printf("this %s rocks!\n", info("package"))
+
+Windows support is enabled by default. All Print functions work as intended.
+However only for color.SprintXXX functions, user should use fmt.FprintXXX and
+set the output to color.Output:
+
+    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
+
+Using with existing code is possible. Just use the Set() method to set the
+standard output to the given parameters. That way a rewrite of an existing
+code is not required.
+
+    // Use handy standard colors.
+    color.Set(color.FgYellow)
+
+    fmt.Println("Existing text will be now in Yellow")
+    fmt.Printf("This one %s\n", "too")
+
+    color.Unset() // don't forget to unset
+
+    // You can mix up parameters
+    color.Set(color.FgMagenta, color.Bold)
+    defer color.Unset() // use it in your function
+
+    fmt.Println("All text will be now bold magenta.")
+
+There might be a case where you want to disable color output (for example to
+pipe the standard output of your app to somewhere else). `Color` has support to
+disable colors both globally and for single color definition. For example
+suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
+the color output with:
+
+    var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+    if *flagNoColor {
+    	color.NoColor = true // disables colorized output
+    }
+
+You can also disable the color by setting the NO_COLOR environment variable to any value.
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+     c := color.New(color.FgCyan)
+     c.Println("Prints cyan text")
+
+     c.DisableColor()
+     c.Println("This is printed without any color")
+
+     c.EnableColor()
+     c.Println("This prints again cyan...")

+## [8.11.5](https://github.com/go-redis/redis/compare/v8.11.4...v8.11.5) (2022-03-17)
+
+
+### Bug Fixes
+
+* add missing Expire methods to Cmdable ([17e3b43](https://github.com/go-redis/redis/commit/17e3b43879d516437ada71cf9c0deac6a382ed9a))
+* add whitespace for avoid unlikely colisions ([7f7c181](https://github.com/go-redis/redis/commit/7f7c1817617cfec909efb13d14ad22ef05a6ad4c))
+* example/otel compile error ([#2028](https://github.com/go-redis/redis/issues/2028)) ([187c07c](https://github.com/go-redis/redis/commit/187c07c41bf68dc3ab280bc3a925e960bbef6475))
+* **extra/redisotel:** set span.kind attribute to client ([065b200](https://github.com/go-redis/redis/commit/065b200070b41e6e949710b4f9e01b50ccc60ab2))
+* format ([96f53a0](https://github.com/go-redis/redis/commit/96f53a0159a28affa94beec1543a62234e7f8b32))
+* invalid type assert in stringArg ([de6c131](https://github.com/go-redis/redis/commit/de6c131865b8263400c8491777b295035f2408e4))

+* set timeout for WAIT command. Fixes [#1963](https://github.com/go-redis/redis/issues/1963) ([333fee1](https://github.com/go-redis/redis/commit/333fee1a8fd98a2fbff1ab187c1b03246a7eb01f))
+* update some argument counts in pre-allocs ([f6974eb](https://github.com/go-redis/redis/commit/f6974ebb5c40a8adf90d2cacab6dc297f4eba4c2))

+
+
+
+## [8.11.4](https://github.com/go-redis/redis/compare/v8.11.3...v8.11.4) (2021-10-04)
+
+
+### Features
+
+* add acl auth support for sentinels ([f66582f](https://github.com/go-redis/redis/commit/f66582f44f3dc3a4705a5260f982043fde4aa634))
+* add Cmd.{String,Int,Float,Bool}Slice helpers and an example ([5d3d293](https://github.com/go-redis/redis/commit/5d3d293cc9c60b90871e2420602001463708ce24))
+* add SetVal method for each command ([168981d](https://github.com/go-redis/redis/commit/168981da2d84ee9e07d15d3e74d738c162e264c4))
+
+
+
+## v8.11
+
+- Remove OpenTelemetry metrics.
+- Supports more redis commands and options.
+
+## v8.10
+
+- Removed extra OpenTelemetry spans from go-redis core. Now go-redis instrumentation only adds a
+  single span with a Redis command (instead of 4 spans). There are multiple reasons behind this
+  decision:
+
+  - Traces become smaller and less noisy.
+  - It may be costly to process those 3 extra spans for each query.
+  - go-redis no longer depends on OpenTelemetry.
+
+  Eventually we hope to replace the information that we no longer collect with OpenTelemetry
+  Metrics.
+
+## v8.9
+
+- Changed `PubSub.Channel` to only rely on `Ping` result. You can now use `WithChannelSize`,
+  `WithChannelHealthCheckInterval`, and `WithChannelSendTimeout` to override default settings.
+
+## v8.8
+
+- To make updating easier, extra modules now have the same version as go-redis does. That means that
+  you need to update your imports:
+
+```
+github.com/go-redis/redis/extra/redisotel -> github.com/go-redis/redis/extra/redisotel/v8
+github.com/go-redis/redis/extra/rediscensus -> github.com/go-redis/redis/extra/rediscensus/v8
+```
+
+## v8.5
+
+- [knadh](https://github.com/knadh) contributed long-awaited ability to scan Redis Hash into a
+  struct:
+
+```go
+err := rdb.HGetAll(ctx, "hash").Scan(&data)
+
+err := rdb.MGet(ctx, "key1", "key2").Scan(&data)
+```
+
+- Please check [redismock](https://github.com/go-redis/redismock) by
+  [monkey92t](https://github.com/monkey92t) if you are looking for mocking Redis Client.
+
+## v8
+
+- All commands require `context.Context` as a first argument, e.g. `rdb.Ping(ctx)`. If you are not
+  using `context.Context` yet, the simplest option is to define global package variable
+  `var ctx = context.TODO()` and use it when `ctx` is required.
+
+- Full support for `context.Context` canceling.
+
+- Added `redis.NewFailoverClusterClient` that supports routing read-only commands to a slave node.
+
+- Added `redisext.OpenTemetryHook` that adds
+  [Redis OpenTelemetry instrumentation](https://redis.uptrace.dev/tracing/).
+
+- Redis slow log support.
+
+- Ring uses Rendezvous Hashing by default which provides better distribution. You need to move
+  existing keys to a new location or keys will be inaccessible / lost. To use old hashing scheme:
+
+```go
+import "github.com/golang/groupcache/consistenthash"
+
+ring := redis.NewRing(&redis.RingOptions{
+    NewConsistentHash: func() {
+        return consistenthash.New(100, crc32.ChecksumIEEE)
+    },
+})
+```
+
+- `ClusterOptions.MaxRedirects` default value is changed from 8 to 3.
+- `Options.MaxRetries` default value is changed from 0 to 3.
+
+- `Cluster.ForEachNode` is renamed to `ForEachShard` for consistency with `Ring`.
+
+## v7.3
+
+- New option `Options.Username` which causes client to use `AuthACL`. Be aware if your connection
+  URL contains username.
+
+## v7.2
+
+- Existing `HMSet` is renamed to `HSet` and old deprecated `HMSet` is restored for Redis 3 users.
+
+## v7.1
+
+- Existing `Cmd.String` is renamed to `Cmd.Text`. New `Cmd.String` implements `fmt.Stringer`
+  interface.
+
+## v7
+
+- _Important_. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a
+  transactional pipeline.
+- WrapProcess is replaced with more convenient AddHook that has access to context.Context.
+- WithContext now can not be used to create a shallow copy of the client.
+- New methods ProcessContext, DoContext, and ExecContext.
+- Client respects Context.Deadline when setting net.Conn deadline.
+- Client listens on Context.Done while waiting for a connection from the pool and returns an error
+  when context context is cancelled.
+- Add PubSub.ChannelWithSubscriptions that sends `*Subscription` in addition to `*Message` to allow
+  detecting reconnections.
+- `time.Time` is now marshalled in RFC3339 format. `rdb.Get("foo").Time()` helper is added to parse
+  the time.
+- `SetLimiter` is removed and added `Options.Limiter` instead.
+- `HMSet` is deprecated as of Redis v4.
+
+## v6.15
+
+- Cluster and Ring pipelines process commands for each node in its own goroutine.
+
+## 6.14
+
+- Added Options.MinIdleConns.
+- Added Options.MaxConnAge.
+- PoolStats.FreeConns is renamed to PoolStats.IdleConns.
+- Add Client.Do to simplify creating custom commands.
+- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
+- Lower memory usage.
+
+## v6.13
+
+- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set
+  `HashReplicas = 1000` for better keys distribution between shards.
+- Cluster client was optimized to use much less memory when reloading cluster state.
+- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout
+  occurres. In most cases it is recommended to use PubSub.Channel instead.
+- Dialer.KeepAlive is set to 5 minutes by default.
+
+## v6.12
+
+- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis
+  Servers that don't have cluster mode enabled. See
+  https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup

+
+## Installation
+
+go-redis supports 2 last Go versions and requires a Go version with
+[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
+module:
+
+```shell
+go mod init github.com/my/repo
+```
+
+And then install go-redis/v8 (note _v8_ in the import; omitting it is a popular mistake):
+
+```shell
+go get github.com/go-redis/redis/v8
+```
+
+## Quickstart
+
+```go
+import (
+    "context"
+    "github.com/go-redis/redis/v8"
+    "fmt"
+)
+
+var ctx = context.Background()
+
+func ExampleClient() {
+    rdb := redis.NewClient(&redis.Options{
+        Addr:     "localhost:6379",
+        Password: "", // no password set
+        DB:       0,  // use default DB
+    })
+
+    err := rdb.Set(ctx, "key", "value", 0).Err()
+    if err != nil {
+        panic(err)
+    }
+
+    val, err := rdb.Get(ctx, "key").Result()
+    if err != nil {
+        panic(err)
+    }
+    fmt.Println("key", val)
+
+    val2, err := rdb.Get(ctx, "key2").Result()
+    if err == redis.Nil {
+        fmt.Println("key2 does not exist")
+    } else if err != nil {
+        panic(err)
+    } else {
+        fmt.Println("key2", val2)
+    }
+    // Output: key value
+    // key2 does not exist
+}
+```
+
+## Look and feel
+
+Some corner cases:
+
+```go
+// SET key value EX 10 NX
+set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
+
+// SET key value keepttl NX
+set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
+
+// SORT list LIMIT 0 2 ASC
+vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
+vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
+    Min: "-inf",
+    Max: "+inf",
+    Offset: 0,
+    Count: 2,

+
+## Run the test
+
+go-redis will start a redis-server and run the test cases.
+
+The paths of redis-server bin file and redis config file are defined in `main_test.go`:
+
+```
+var (
+	redisServerBin, _  = filepath.Abs(filepath.Join("testdata", "redis", "src", "redis-server"))
+	redisServerConf, _ = filepath.Abs(filepath.Join("testdata", "redis", "redis.conf"))
+)
+```
+
+For local testing, you can change the variables to refer to your local files, or create a soft link
+to the corresponding folder for redis-server and copy the config file to `testdata/redis/`:
+
+```
+ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
+cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/
+```
+
+Lastly, run:
+
+```
+go test
+```

+ - Exported errors to allow easy checking from application code
+ - Enabled TCP Keepalives on TCP connections
+ - Optimized INFILE handling (better buffer size calculation, lazy init, ...)
+ - The DSN parser also checks for a missing separating slash
+ - Faster binary date / datetime to string formatting
+ - Also exported the MySQLWarning type
+ - mysqlConn.Close returns the first error encountered instead of ignoring all errors
+ - writePacket() automatically writes the packet size to the header
+ - readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
+
+New Features:
+
+ - `RegisterDial` allows the usage of a custom dial function to establish the network connection
+ - Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter

+
+
+## Version 1.1 (2013-11-02)
+
+Changes:
+
+  - Go-MySQL-Driver now requires Go 1.1
+  - Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
+  - Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
+  - `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
+  - DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
+  - Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
+  - Optimized the buffer for reading
+  - stmt.Query now caches column metadata
+  - New Logo
+  - Changed the copyright header to include all contributors
+  - Improved the LOAD INFILE documentation
+  - The driver struct is now exported to make the driver directly accessible
+  - Refactored the driver tests
+  - Added more benchmarks and moved all to a separate file
+  - Other small refactoring
+
+New Features:
+
+  - Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
+  - Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
+  - Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
+
+Bugfixes:
+
+  - Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
+  - Convert to DB timezone when inserting `time.Time`
+  - Splitted packets (more than 16MB) are now merged correctly
+  - Fixed false positive `io.EOF` errors when the data was fully read
+  - Avoid panics on reuse of closed connections
+  - Fixed empty string producing false nil values
+  - Fixed sign byte for positive TIME fields
+

+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to

+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions

+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+
+## Installation
+Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
+```bash
+$ go get -u github.com/go-sql-driver/mysql
+```
+Make sure [Git is installed](https://git-scm.com/downloads) on your machine and in your system's `PATH`.
+
+## Usage
+_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
+
+Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name)  as `dataSourceName`:
+
+```go
+import (
+	"database/sql"
+	"time"
+
+	_ "github.com/go-sql-driver/mysql"
+)
+
+// ...
+
+db, err := sql.Open("mysql", "user:password@/dbname")
+if err != nil {
+	panic(err)
+}
+// See "Important settings" section.
+db.SetConnMaxLifetime(time.Minute * 3)
+db.SetMaxOpenConns(10)
+db.SetMaxIdleConns(10)
+```
+
+[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
+
+### Important settings
+
+`db.SetConnMaxLifetime()` is required to ensure connections are closed by the driver safely before connection is closed by MySQL server, OS, or other middlewares. Since some middlewares close idle connections by 5 minutes, we recommend timeout shorter than 5 minutes. This setting helps load balancing and changing system variables too.
+
+`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server.
+
+`db.SetMaxIdleConns()` is recommended to be set same to (or greater than) `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed very frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15.
+
+
+### DSN (Data Source Name)
+
+The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
+```
+[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
+```
+
+A DSN in its fullest form:
+```
+username:password@protocol(address)/dbname?param=value
+```
+
+Except for the databasename, all values are optional. So the minimal DSN is:
+```
+/dbname
+```
+
+If you do not want to preselect a database, leave `dbname` empty:
+```
+/
+```
+This has the same effect as an empty DSN string:
+```
+
+```
+
+Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
+
+#### Password
+Passwords can consist of any character. Escaping is **not** necessary.
+
+#### Protocol
+See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available.
+In general you should use an Unix domain socket if available and TCP otherwise for best performance.
+
+#### Address
+For TCP and UDP networks, addresses have the form `host[:port]`.
+If `port` is omitted, the default port will be used.
+If `host` is a literal IPv6 address, it must be enclosed in square brackets.
+The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
+
+For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
+
+#### Parameters
+*Parameters are case-sensitive!*
+
+Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
+
+##### `allowAllFiles`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowAllFiles=true` disables the file allowlist for `LOAD DATA LOCAL INFILE` and allows *all* files.
+[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
+
+##### `allowCleartextPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowCleartextPasswords=true` allows using the [cleartext client side plugin](https://dev.mysql.com/doc/en/cleartext-pluggable-authentication.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
+
+##### `allowNativePasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        true
+```
+`allowNativePasswords=false` disallows the usage of MySQL native password method.
+
+##### `allowOldPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
+
+##### `charset`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
+
+Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
+Unless you need the fallback behavior, please use `collation` instead.
+
+##### `checkConnLiveness`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        true
+```
+
+On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection.
+`checkConnLiveness=false` disables this liveness check of connections.
+
+##### `collation`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        utf8mb4_general_ci
+```
+
+Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
+
+A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
+
+The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5.  You should use an older collation (e.g. `utf8_general_ci`) for older MySQL.
+
+Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).
+
+
+##### `clientFoundRows`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
+
+##### `columnsWithAlias`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
+
+```
+SELECT u.id FROM users as u
+```
+
+will return `u.id` instead of just `id` if `columnsWithAlias=true`.
+
+##### `interpolateParams`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
+
+*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are rejected as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
+
+##### `loc`
+
+```
+Type:           string
+Valid Values:   <escaped name>
+Default:        UTC
+```
+
+Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
+
+Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
+
+Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
+
+##### `maxAllowedPacket`
+```
+Type:          decimal number
+Default:       4194304
+```
+
+Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
+
+##### `multiStatements`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
+
+When `multiStatements` is used, `?` parameters must only be used in the first statement.
+
+##### `parseTime`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
+The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
+
+
+##### `readTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+##### `rejectReadOnly`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+
+`rejectReadOnly=true` causes the driver to reject read-only connections. This
+is for a possible race condition during an automatic failover, where the mysql
+client gets connected to a read-only replica after the failover.
+
+Note that this should be a fairly rare case, as an automatic failover normally
+happens when the primary is down, and the race condition shouldn't happen
+unless it comes back up online as soon as the failover is kicked off. On the
+other hand, when this happens, a MySQL application can get stuck on a
+read-only connection until restarted. It is however fairly easy to reproduce,
+for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
+
+If you are not relying on read-only transactions to reject writes that aren't
+supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
+is safer for failovers.
+
+Note that ERROR 1290 can be returned for a `read-only` server and this option will
+cause a retry for that error. However the same error number is used for some
+other cases. You should ensure your application will never cause an ERROR 1290
+except for `read-only` mode when enabling this option.
+
+
+##### `serverPubKey`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
+Public keys are used to transmit encrypted data, e.g. for authentication.
+If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
+
+
+##### `timeout`
+
+```
+Type:           duration
+Default:        OS default
+```
+
+Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+
+##### `tls`
+
+```
+Type:           bool / string
+Valid Values:   true, false, skip-verify, preferred, <name>
+Default:        false
+```
+
+`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security. You can use a custom TLS config after registering it with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
+
+
+##### `writeTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+
+##### System Variables
+
+Any other parameters are interpreted as system variables:
+  * `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
+  * `<enum_var>=<value>`: `SET <enum_var>=<value>`
+  * `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
+
+Rules:
+* The values for string variables must be quoted with `'`.
+* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
+ (which implies values of string variables must be wrapped with `%27`).
+
+Examples:
+  * `autocommit=1`: `SET autocommit=1`
+  * [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
+  * [`transaction_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_transaction_isolation): `SET transaction_isolation='REPEATABLE-READ'`
+
+
+#### Examples
+```
+user@unix(/path/to/socket)/dbname
+```
+
+```
+root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
+```
+
+```
+user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
+```
+
+Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
+```
+user:password@/dbname?sql_mode=TRADITIONAL
+```
+
+TCP via IPv6:
+```
+user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
+```
+
+TCP on a remote host, e.g. Amazon RDS:
+```
+id:password@tcp(your-amazonaws-uri.com:3306)/dbname
+```
+
+Google Cloud SQL on App Engine:
+```
+user:password@unix(/cloudsql/project-id:region-name:instance-name)/dbname
+```
+
+TCP using default port (3306) on localhost:
+```
+user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
+```
+
+Use the default protocol (tcp) and host (localhost:3306):
+```
+user:password@/dbname
+```
+
+No Database preselected:
+```
+user:password@/
+```
+
+
+### Connection pool and timeouts
+The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
+
+## `ColumnType` Support
+This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
+
+## `context.Context` Support
+Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
+See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
+
+
+### `LOAD DATA LOCAL INFILE` support
+For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
+```go
+import "github.com/go-sql-driver/mysql"
+```
+
+Files must be explicitly allowed by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the allowlist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
+
+To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
+
+See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
+
+
+### `time.Time` support
+The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
+
+However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical equivalent in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
+
+**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
+
+
+### Unicode support
+Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
+
+Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
+
+Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
+
+See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
+
+## Testing / Development
+To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.

+
+# Why a new library?
+
+As of this writing, there already exists a de facto standard library for YAML processing for Go: [https://github.com/go-yaml/yaml](https://github.com/go-yaml/yaml). However we feel that some features are lacking, namely:
+
+- Pretty format for error notifications
+- Direct manipulation of YAML abstract syntax tree
+- Support for `Anchor` and `Alias` when marshaling
+- Allow referencing elements declared in another file via anchors
+
+# Features
+
+- Pretty format for error notifications
+- Supports `Scanner` or `Lexer` or `Parser` as public API
+- Supports `Anchor` and `Alias` to Marshaler
+- Allow referencing elements declared in another file via anchors
+- Extract value or AST by YAMLPath ( YAMLPath is like a JSONPath )
+
+# Installation
+
+```sh
+go get -u github.com/goccy/go-yaml
+```
+
+# Synopsis
+
+## 1. Simple Encode/Decode
+
+Has an interface like `go-yaml/yaml` using `reflect`
+
+```go
+var v struct {
+	A int
+	B string
+}
+v.A = 1
+v.B = "hello"
+bytes, err := yaml.Marshal(v)
+if err != nil {
+	//...
+}
+fmt.Println(string(bytes)) // "a: 1\nb: hello\n"
+```
+
+```go
+	yml := `
+%YAML 1.2
+---
+a: 1
+b: c
+`
+var v struct {
+	A int
+	B string
+}
+if err := yaml.Unmarshal([]byte(yml), &v); err != nil {
+	//...
+}
+```
+
+To control marshal/unmarshal behavior, you can use the `yaml` tag.
+
+```go
+	yml := `---
+foo: 1
+bar: c
+`
+var v struct {
+	A int    `yaml:"foo"`
+	B string `yaml:"bar"`
+}
+if err := yaml.Unmarshal([]byte(yml), &v); err != nil {
+	//...
+}
+```
+
+For convenience, we also accept the `json` tag. Note that not all options from
+the `json` tag will have significance when parsing YAML documents. If both
+tags exist, `yaml` tag will take precedence.
+
+```go
+	yml := `---
+foo: 1
+bar: c
+`
+var v struct {
+	A int    `json:"foo"`
+	B string `json:"bar"`
+}
+if err := yaml.Unmarshal([]byte(yml), &v); err != nil {
+	//...
+}
+```
+
+For custom marshal/unmarshaling, implement either `Bytes` or `Interface` variant of marshaler/unmarshaler. The difference is that while `BytesMarshaler`/`BytesUnmarshaler` behaves like [`encoding/json`](https://pkg.go.dev/encoding/json) and `InterfaceMarshaler`/`InterfaceUnmarshaler` behaves like [`gopkg.in/yaml.v2`](https://pkg.go.dev/gopkg.in/yaml.v2).
+
+Semantically both are the same, but they differ in performance. Because indentation matters in YAML, you cannot simply accept a valid YAML fragment from a Marshaler, and expect it to work when it is attached to the parent container's serialized form. Therefore when we receive use the `BytesMarshaler`, which returns `[]byte`, we must decode it once to figure out how to make it work in the given context. If you use the `InterfaceMarshaler`, we can skip the decoding.
+
+If you are repeatedly marshaling complex objects, the latter is always better
+performance wise. But if you are, for example, just providing a choice between
+a config file format that is read only once, the former is probably easier to
+code.
+
+## 2. Reference elements declared in another file
+
+`testdata` directory contains `anchor.yml` file:
+
+```shell
+├── testdata
+   └── anchor.yml
+```
+
+And `anchor.yml` is defined as follows:
+
+```yaml
+a: &a
+  b: 1
+  c: hello
+```
+
+Then, if `yaml.ReferenceDirs("testdata")` option is passed to `yaml.Decoder`, 
+ `Decoder` tries to find the anchor definition from YAML files the under `testdata` directory.
+ 
+```go
+buf := bytes.NewBufferString("a: *a\n")
+dec := yaml.NewDecoder(buf, yaml.ReferenceDirs("testdata"))
+var v struct {
+	A struct {
+		B int
+		C string
+	}
+}
+if err := dec.Decode(&v); err != nil {
+	//...
+}
+fmt.Printf("%+v\n", v) // {A:{B:1 C:hello}}
+```
+
+## 3. Encode with `Anchor` and `Alias`
+
+### 3.1. Explicitly declared `Anchor` name and `Alias` name
+
+If you want to use `anchor` or `alias`, you can define it as a struct tag.
+
+```go
+type T struct {
+  A int
+  B string
+}
+var v struct {
+  C *T `yaml:"c,anchor=x"`
+  D *T `yaml:"d,alias=x"`
+}
+v.C = &T{A: 1, B: "hello"}
+v.D = v.C
+bytes, err := yaml.Marshal(v)
+if err != nil {
+  panic(err)
+}
+fmt.Println(string(bytes))
+/*
+c: &x
+  a: 1
+  b: hello
+d: *x
+*/
+```
+
+### 3.2. Implicitly declared `Anchor` and `Alias` names
+
+If you do not explicitly declare the anchor name, the default behavior is to
+use the equivalent of `strings.ToLower($FieldName)` as the name of the anchor.
+
+If you do not explicitly declare the alias name AND the value is a pointer
+to another element, we look up the anchor name by finding out which anchor
+field the value is assigned to by looking up its pointer address.
+
+```go
+type T struct {
+	I int
+	S string
+}
+var v struct {
+	A *T `yaml:"a,anchor"`
+	B *T `yaml:"b,anchor"`
+	C *T `yaml:"c,alias"`
+	D *T `yaml:"d,alias"`
+}
+v.A = &T{I: 1, S: "hello"}
+v.B = &T{I: 2, S: "world"}
+v.C = v.A // C has same pointer address to A
+v.D = v.B // D has same pointer address to B
+bytes, err := yaml.Marshal(v)
+if err != nil {
+	//...
+}
+fmt.Println(string(bytes)) 
+/*
+a: &a
+  i: 1
+  s: hello
+b: &b
+  i: 2
+  s: world
+c: *a
+d: *b
+*/
+```
+
+### 3.3 MergeKey and Alias
+
+Merge key and alias ( `<<: *alias` ) can be used by embedding a structure with the `inline,alias` tag.
+
+```go
+type Person struct {
+	*Person `yaml:",omitempty,inline,alias"` // embed Person type for default value
+	Name    string `yaml:",omitempty"`
+	Age     int    `yaml:",omitempty"`
+}
+defaultPerson := &Person{
+	Name: "John Smith",
+	Age:  20,
+}
+people := []*Person{
+	{
+		Person: defaultPerson, // assign default value
+		Name:   "Ken",         // override Name property
+		Age:    10,            // override Age property
+	},
+	{
+		Person: defaultPerson, // assign default value only
+	},
+}
+var doc struct {
+	Default *Person   `yaml:"default,anchor"`
+	People  []*Person `yaml:"people"`
+}
+doc.Default = defaultPerson
+doc.People = people
+bytes, err := yaml.Marshal(doc)
+if err != nil {
+	//...
+}
+fmt.Println(string(bytes))
+/*
+default: &default
+  name: John Smith
+  age: 20
+people:
+- <<: *default
+  name: Ken
+  age: 10
+- <<: *default
+*/
+```
+
+## 4. Pretty Formatted Errors
+
+Error values produced during parsing have two extra features over regular
+error values.
+
+First, by default, they contain extra information on the location of the error
+from the source YAML document, to make it easier to find the error location.
+
+Second, the error messages can optionally be colorized.
+
+If you would like to control exactly how the output looks like, consider
+using  `yaml.FormatError`, which accepts two boolean values to
+control turning these features on or off.
+
+<img src="https://user-images.githubusercontent.com/209884/67358124-587f0980-f59a-11e9-96fc-7205aab77695.png"></img>
+
+## 5. Use YAMLPath
+
+```go
+yml := `
+store:
+  book:
+    - author: john
+      price: 10
+    - author: ken
+      price: 12
+  bicycle:
+    color: red
+    price: 19.95
+`
+path, err := yaml.PathString("$.store.book[*].author")
+if err != nil {
+  //...
+}
+var authors []string
+if err := path.Read(strings.NewReader(yml), &authors); err != nil {
+  //...
+}
+fmt.Println(authors)
+// [john ken]
+```
+
+### 5.1 Print customized error with YAML source code
+
+```go
+package main
+
+import (
+  "fmt"
+
+  "github.com/goccy/go-yaml"
+)
+
+func main() {
+  yml := `
+a: 1
+b: "hello"
+`
+  var v struct {
+    A int
+    B string
+  }
+  if err := yaml.Unmarshal([]byte(yml), &v); err != nil {
+    panic(err)
+  }
+  if v.A != 2 {
+    // output error with YAML source
+    path, err := yaml.PathString("$.a")
+    if err != nil {
+      panic(err)
+    }
+    source, err := path.AnnotateSource([]byte(yml), true)
+    if err != nil {
+      panic(err)
+    }
+    fmt.Printf("a value expected 2 but actual %d:\n%s\n", v.A, string(source))
+  }
+}
+```
+

+//
+// The field tag format accepted is:
+//
+//     `(...) yaml:"[<key>][,<flag1>[,<flag2>]]" (...)`
+//
+// The following flags are currently supported:
+//
+//     omitempty    Only include the field if it's not set to the zero
+//                  value for the type or to empty slices or maps.
+//                  Zero valued structs will be omitted if all their public
+//                  fields are zero, unless they implement an IsZero
+//                  method (see the IsZeroer interface type), in which
+//                  case the field will be included if that method returns true.
+//
+//     flow         Marshal using a flow style (useful for structs,
+//                  sequences and maps).
+//
+//     inline       Inline the field, which must be a struct or a map,
+//                  causing all of its fields or keys to be processed as if
+//                  they were part of the outer struct. For maps, keys must
+//                  not conflict with the yaml keys of other struct fields.
+//
+//     anchor       Marshal with anchor. If want to define anchor name explicitly, use anchor=name style.
+//                  Otherwise, if used 'anchor' name only, used the field name lowercased as the anchor name
+//
+//     alias        Marshal with alias. If want to define alias name explicitly, use alias=name style.
+//                  Otherwise, If omitted alias name and the field type is pointer type,
+//                  assigned anchor name automatically from same pointer address.
+//
+// In addition, if the key is "-", the field is ignored.

+# uuid ![build status](https://travis-ci.org/google/uuid.svg?branch=master)
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
+

+go-flags: a go library for parsing command line arguments
+=========================================================
+
+[![GoDoc](https://godoc.org/github.com/jessevdk/go-flags?status.png)](https://godoc.org/github.com/jessevdk/go-flags) [![Build Status](https://travis-ci.org/jessevdk/go-flags.svg?branch=master)](https://travis-ci.org/jessevdk/go-flags) [![Coverage Status](https://img.shields.io/coveralls/jessevdk/go-flags.svg)](https://coveralls.io/r/jessevdk/go-flags?branch=master)
+
+This library provides similar functionality to the builtin flag library of
+go, but provides much more functionality and nicer formatting. From the
+documentation:
+
+Package flags provides an extensive command line option parser.
+The flags package is similar in functionality to the go builtin flag package
+but provides more options and uses reflection to provide a convenient and
+succinct way of specifying command line options.
+
+Supported features:
+* Options with short names (-v)
+* Options with long names (--verbose)
+* Options with and without arguments (bool v.s. other type)
+* Options with optional arguments and default values
+* Multiple option groups each containing a set of options
+* Generate and print well-formatted help message
+* Passing remaining command line arguments after -- (optional)
+* Ignoring unknown command line options (optional)
+* Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
+* Supports multiple short options -aux
+* Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
+* Supports same option multiple times (can store in slice or last option counts)
+* Supports maps
+* Supports function callbacks
+* Supports namespaces for (nested) option groups
+
+The flags package uses structs, reflection and struct field tags
+to allow users to specify command line options. This results in very simple
+and concise specification of your application options. For example:
+
+```go
+type Options struct {
+	Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+}
+```
+
+This specifies one option with a short name -v and a long name --verbose.
+When either -v or --verbose is found on the command line, a 'true' value
+will be appended to the Verbose field. e.g. when specifying -vvv, the
+resulting value of Verbose will be {[true, true, true]}.
+
+Example:
+--------
+```go
+var opts struct {
+	// Slice of bool will append 'true' each time the option
+	// is encountered (can be set multiple times, like -vvv)
+	Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+
+	// Example of automatic marshalling to desired type (uint)
+	Offset uint `long:"offset" description:"Offset"`
+
+	// Example of a callback, called each time the option is found.
+	Call func(string) `short:"c" description:"Call phone number"`
+
+	// Example of a required flag
+	Name string `short:"n" long:"name" description:"A name" required:"true"`
+
+	// Example of a flag restricted to a pre-defined set of strings
+	Animal string `long:"animal" choice:"cat" choice:"dog"`
+
+	// Example of a value name
+	File string `short:"f" long:"file" description:"A file" value-name:"FILE"`
+
+	// Example of a pointer
+	Ptr *int `short:"p" description:"A pointer to an integer"`
+
+	// Example of a slice of strings
+	StringSlice []string `short:"s" description:"A slice of strings"`
+
+	// Example of a slice of pointers
+	PtrSlice []*string `long:"ptrslice" description:"A slice of pointers to string"`
+
+	// Example of a map
+	IntMap map[string]int `long:"intmap" description:"A map from string to int"`
+}
+
+// Callback which will invoke callto:<argument> to call a number.
+// Note that this works just on OS X (and probably only with
+// Skype) but it shows the idea.
+opts.Call = func(num string) {
+	cmd := exec.Command("open", "callto:"+num)
+	cmd.Start()
+	cmd.Process.Release()
+}
+
+// Make some fake arguments to parse.
+args := []string{
+	"-vv",
+	"--offset=5",
+	"-n", "Me",
+	"--animal", "dog", // anything other than "cat" or "dog" will raise an error
+	"-p", "3",
+	"-s", "hello",
+	"-s", "world",
+	"--ptrslice", "hello",
+	"--ptrslice", "world",
+	"--intmap", "a:1",
+	"--intmap", "b:5",
+	"arg1",
+	"arg2",
+	"arg3",
+}
+
+// Parse flags from `args'. Note that here we use flags.ParseArgs for
+// the sake of making a working example. Normally, you would simply use
+// flags.Parse(&opts) which uses os.Args
+args, err := flags.ParseArgs(&opts, args)
+
+if err != nil {
+	panic(err)
+}
+
+fmt.Printf("Verbosity: %v\n", opts.Verbose)
+fmt.Printf("Offset: %d\n", opts.Offset)
+fmt.Printf("Name: %s\n", opts.Name)
+fmt.Printf("Animal: %s\n", opts.Animal)
+fmt.Printf("Ptr: %d\n", *opts.Ptr)
+fmt.Printf("StringSlice: %v\n", opts.StringSlice)
+fmt.Printf("PtrSlice: [%v %v]\n", *opts.PtrSlice[0], *opts.PtrSlice[1])
+fmt.Printf("IntMap: [a:%v b:%v]\n", opts.IntMap["a"], opts.IntMap["b"])
+fmt.Printf("Remaining args: %s\n", strings.Join(args, " "))
+
+// Output: Verbosity: [true true]
+// Offset: 5
+// Name: Me
+// Ptr: 3
+// StringSlice: [hello world]
+// PtrSlice: [hello world]
+// IntMap: [a:1 b:5]
+// Remaining args: arg1 arg2 arg3

+Package flags provides an extensive command line option parser.
+The flags package is similar in functionality to the go built-in flag package
+but provides more options and uses reflection to provide a convenient and
+succinct way of specifying command line options.
+
+
+Supported features
+
+The following features are supported in go-flags:
+
+    Options with short names (-v)
+    Options with long names (--verbose)
+    Options with and without arguments (bool v.s. other type)
+    Options with optional arguments and default values
+    Option default values from ENVIRONMENT_VARIABLES, including slice and map values
+    Multiple option groups each containing a set of options
+    Generate and print well-formatted help message
+    Passing remaining command line arguments after -- (optional)
+    Ignoring unknown command line options (optional)
+    Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
+    Supports multiple short options -aux
+    Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
+    Supports same option multiple times (can store in slice or last option counts)
+    Supports maps
+    Supports function callbacks
+    Supports namespaces for (nested) option groups
+
+Additional features specific to Windows:
+    Options with short names (/v)
+    Options with long names (/verbose)
+    Windows-style options with arguments use a colon as the delimiter
+    Modify generated help message with Windows-style / options
+    Windows style options can be disabled at build time using the "forceposix"
+    build tag
+
+
+Basic usage
+
+The flags package uses structs, reflection and struct field tags
+to allow users to specify command line options. This results in very simple
+and concise specification of your application options. For example:
+
+    type Options struct {
+        Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+    }
+
+This specifies one option with a short name -v and a long name --verbose.
+When either -v or --verbose is found on the command line, a 'true' value
+will be appended to the Verbose field. e.g. when specifying -vvv, the
+resulting value of Verbose will be {[true, true, true]}.
+
+Slice options work exactly the same as primitive type options, except that
+whenever the option is encountered, a value is appended to the slice.
+
+Map options from string to primitive type are also supported. On the command
+line, you specify the value for such an option as key:value. For example
+
+    type Options struct {
+        AuthorInfo string[string] `short:"a"`
+    }
+
+Then, the AuthorInfo map can be filled with something like
+-a name:Jesse -a "surname:van den Kieboom".
+
+Finally, for full control over the conversion between command line argument
+values and options, user defined types can choose to implement the Marshaler
+and Unmarshaler interfaces.
+
+
+Available field tags
+
+The following is a list of tags for struct fields supported by go-flags:
+
+    short:            the short name of the option (single character)
+    long:             the long name of the option
+    required:         if non empty, makes the option required to appear on the command
+                      line. If a required option is not present, the parser will
+                      return ErrRequired (optional)
+    description:      the description of the option (optional)
+    long-description: the long description of the option. Currently only
+                      displayed in generated man pages (optional)
+    no-flag:          if non-empty, this field is ignored as an option (optional)
+
+    optional:       if non-empty, makes the argument of the option optional. When an
+                    argument is optional it can only be specified using
+                    --option=argument (optional)
+    optional-value: the value of an optional option when the option occurs
+                    without an argument. This tag can be specified multiple
+                    times in the case of maps or slices (optional)
+    default:        the default value of an option. This tag can be specified
+                    multiple times in the case of slices or maps (optional)
+    default-mask:   when specified, this value will be displayed in the help
+                    instead of the actual default value. This is useful
+                    mostly for hiding otherwise sensitive information from
+                    showing up in the help. If default-mask takes the special
+                    value "-", then no default value will be shown at all
+                    (optional)
+    env:            the default value of the option is overridden from the
+                    specified environment variable, if one has been defined.
+                    (optional)
+    env-delim:      the 'env' default value from environment is split into
+                    multiple values with the given delimiter string, use with
+                    slices and maps (optional)
+    value-name:     the name of the argument value (to be shown in the help)
+                    (optional)
+    choice:         limits the values for an option to a set of values.
+                    Repeat this tag once for each allowable value.
+                    e.g. `long:"animal" choice:"cat" choice:"dog"`
+    hidden:         if non-empty, the option is not visible in the help or man page.
+
+    base: a base (radix) used to convert strings to integer values, the
+          default base is 10 (i.e. decimal) (optional)
+
+    ini-name:       the explicit ini option name (optional)
+    no-ini:         if non-empty this field is ignored as an ini option
+                    (optional)
+
+    group:                when specified on a struct field, makes the struct
+                          field a separate group with the given name (optional)
+    namespace:            when specified on a group struct field, the namespace
+                          gets prepended to every option's long name and
+                          subgroup's namespace of this group, separated by
+                          the parser's namespace delimiter (optional)
+    env-namespace:        when specified on a group struct field, the env-namespace
+                          gets prepended to every option's env key and
+                          subgroup's env-namespace of this group, separated by
+                          the parser's env-namespace delimiter (optional)
+    command:              when specified on a struct field, makes the struct
+                          field a (sub)command with the given name (optional)
+    subcommands-optional: when specified on a command struct field, makes
+                          any subcommands of that command optional (optional)
+    alias:                when specified on a command struct field, adds the
+                          specified name as an alias for the command. Can be
+                          be specified multiple times to add more than one
+                          alias (optional)
+    positional-args:      when specified on a field with a struct type,
+                          uses the fields of that struct to parse remaining
+                          positional command line arguments into (in order
+                          of the fields). If a field has a slice type,
+                          then all remaining arguments will be added to it.
+                          Positional arguments are optional by default,
+                          unless the "required" tag is specified together
+                          with the "positional-args" tag. The "required" tag
+                          can also be set on the individual rest argument
+                          fields, to require only the first N positional
+                          arguments. If the "required" tag is set on the
+                          rest arguments slice, then its value determines
+                          the minimum amount of rest arguments that needs to
+                          be provided (e.g. `required:"2"`) (optional)
+    positional-arg-name:  used on a field in a positional argument struct; name
+                          of the positional argument placeholder to be shown in
+                          the help (optional)
+
+Either the `short:` tag or the `long:` must be specified to make the field eligible as an
+option.
+
+
+Option groups
+
+Option groups are a simple way to semantically separate your options. All
+options in a particular group are shown together in the help under the name
+of the group. Namespaces can be used to specify option long names more
+precisely and emphasize the options affiliation to their group.
+
+There are currently three ways to specify option groups.
+
+    1. Use NewNamedParser specifying the various option groups.
+    2. Use AddGroup to add a group to an existing parser.
+    3. Add a struct field to the top-level options annotated with the
+       group:"group-name" tag.
+
+
+
+Commands
+
+The flags package also has basic support for commands. Commands are often
+used in monolithic applications that support various commands or actions.
+Take git for example, all of the add, commit, checkout, etc. are called
+commands. Using commands you can easily separate multiple functions of your
+application.
+
+There are currently two ways to specify a command.
+
+    1. Use AddCommand on an existing parser.
+    2. Add a struct field to your options struct annotated with the
+       command:"command-name" tag.
+
+The most common, idiomatic way to implement commands is to define a global
+parser instance and implement each command in a separate file. These
+command files should define a go init function which calls AddCommand on
+the global parser.
+
+When parsing ends and there is an active command and that command implements
+the Commander interface, then its Execute method will be run with the
+remaining command line arguments.
+
+Command structs can have options which become valid to parse after the
+command has been specified on the command line, in addition to the options
+of all the parent commands. I.e. considering a -v flag on the parser and an
+add command, the following are equivalent:
+
+    ./app -v add
+    ./app add -v
+
+However, if the -v flag is defined on the add command, then the first of
+the two examples above would fail since the -v flag is not defined before
+the add command.
+
+
+Completion
+
+go-flags has builtin support to provide bash completion of flags, commands
+and argument values. To use completion, the binary which uses go-flags
+can be invoked in a special environment to list completion of the current
+command line argument. It should be noted that this `executes` your application,
+and it is up to the user to make sure there are no negative side effects (for
+example from init functions).
+
+Setting the environment variable `GO_FLAGS_COMPLETION=1` enables completion
+by replacing the argument parsing routine with the completion routine which
+outputs completions for the passed arguments. The basic invocation to
+complete a set of arguments is therefore:
+
+    GO_FLAGS_COMPLETION=1 ./completion-example arg1 arg2 arg3
+
+where `completion-example` is the binary, `arg1` and `arg2` are
+the current arguments, and `arg3` (the last argument) is the argument
+to be completed. If the GO_FLAGS_COMPLETION is set to "verbose", then
+descriptions of possible completion items will also be shown, if there
+are more than 1 completion items.
+
+To use this with bash completion, a simple file can be written which
+calls the binary which supports go-flags completion:
+
+    _completion_example() {
+        # All arguments except the first one
+        args=("${COMP_WORDS[@]:1:$COMP_CWORD}")
+
+        # Only split on newlines
+        local IFS=$'\n'
+
+        # Call completion (note that the first element of COMP_WORDS is
+        # the executable itself)
+        COMPREPLY=($(GO_FLAGS_COMPLETION=1 ${COMP_WORDS[0]} "${args[@]}"))
+        return 0
+    }
+
+    complete -F _completion_example completion-example
+
+Completion requires the parser option PassDoubleDash and is therefore enforced if the environment variable GO_FLAGS_COMPLETION is set.
+
+Customized completion for argument values is supported by implementing
+the flags.Completer interface for the argument value type. An example
+of a type which does so is the flags.Filename type, an alias of string
+allowing simple filename completion. A slice or array argument value
+whose element type implements flags.Completer will also be completed.

+
+[![Build Status](https://travis-ci.org/jmoiron/sqlx.svg?branch=master)](https://travis-ci.org/jmoiron/sqlx) [![Coverage Status](https://coveralls.io/repos/github/jmoiron/sqlx/badge.svg?branch=master)](https://coveralls.io/github/jmoiron/sqlx?branch=master) [![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/jmoiron/sqlx) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/jmoiron/sqlx/master/LICENSE)
+
+sqlx is a library which provides a set of extensions on go's standard
+`database/sql` library.  The sqlx versions of `sql.DB`, `sql.TX`, `sql.Stmt`,
+et al. all leave the underlying interfaces untouched, so that their interfaces
+are a superset on the standard ones.  This makes it relatively painless to
+integrate existing codebases using database/sql with sqlx.
+
+Major additional concepts are:
+
+* Marshal rows into structs (with embedded struct support), maps, and slices
+* Named parameter support including prepared statements
+* `Get` and `Select` to go quickly from query to struct/slice
+
+In addition to the [godoc API documentation](http://godoc.org/github.com/jmoiron/sqlx),
+there is also some [user documentation](http://jmoiron.github.io/sqlx/) that
+explains how to use `database/sql` along with sqlx.
+
+## Recent Changes
+
+1.3.0:
+
+* `sqlx.DB.Connx(context.Context) *sqlx.Conn`
+* `sqlx.BindDriver(driverName, bindType)`
+* support for `[]map[string]interface{}` to do "batch" insertions
+* allocation & perf improvements for `sqlx.In`
+
+DB.Connx returns an `sqlx.Conn`, which is an `sql.Conn`-alike consistent with
+sqlx's wrapping of other types.
+
+`BindDriver` allows users to control the bindvars that sqlx will use for drivers,
+and add new drivers at runtime.  This results in a very slight performance hit
+when resolving the driver into a bind type (~40ns per call), but it allows users
+to specify what bindtype their driver uses even when sqlx has not been updated
+to know about it by default.
+
+### Backwards Compatibility
+
+Compatibility with the most recent two versions of Go is a requirement for any
+new changes.  Compatibility beyond that is not guaranteed.
+
+Versioning is done with Go modules.  Breaking changes (eg. removing deprecated API)
+will get major version number bumps.
+
+## install
+
+    go get github.com/jmoiron/sqlx
+
+## issues
+
+Row headers can be ambiguous (`SELECT 1 AS a, 2 AS a`), and the result of
+`Columns()` does not fully qualify column names in queries like:
+
+```sql
+SELECT a.id, a.name, b.id, b.name FROM foos AS a JOIN foos AS b ON a.parent = b.id;
+```
+
+making a struct or map destination ambiguous.  Use `AS` in your queries
+to give columns distinct names, `rows.Scan` to scan them manually, or 
+`SliceScan` to get a slice of results.
+
+## usage
+
+Below is an example which shows some common use cases for sqlx.  Check 
+[sqlx_test.go](https://github.com/jmoiron/sqlx/blob/master/sqlx_test.go) for more
+usage.

+# reflectx
+
+The sqlx package has special reflect needs.  In particular, it needs to:
+
+* be able to map a name to a field
+* understand embedded structs
+* understand mapping names to fields by a particular tag
+* user specified name -> field mapping functions
+
+These behaviors mimic the behaviors by the standard library marshallers and also the
+behavior of standard Go accessors.
+
+The first two are amply taken care of by `Reflect.Value.FieldByName`, and the third is
+addressed by `Reflect.Value.FieldByNameFunc`, but these don't quite understand struct
+tags in the ways that are vital to most marshallers, and they are slow.
+
+This reflectx package extends reflect to achieve these goals.

+# pq - A pure Go postgres driver for Go's database/sql package
+
+[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://pkg.go.dev/github.com/lib/pq?tab=doc)
+
+## Install
+
+	go get github.com/lib/pq
+
+## Features
+
+* SSL
+* Handles bad connections for `database/sql`
+* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
+* Scan binary blobs correctly (i.e. `bytea`)
+* Package for `hstore` support
+* COPY FROM support
+* pq.ParseURL for converting urls to connection strings for sql.Open.
+* Many libpq compatible environment variables
+* Unix socket support
+* Notifications: `LISTEN`/`NOTIFY`
+* pgpass support
+* GSS (Kerberos) auth
+
+## Tests
+
+`go test` is used for testing.  See [TESTS.md](TESTS.md) for more details.
+
+## Status
+
+This package is currently in maintenance mode, which means:
+1.   It generally does not accept new features.
+2.   It does accept bug fixes and version compatability changes provided by the community.
+3.   Maintainers usually do not resolve reported issues.
+4.   Community members are encouraged to help each other with reported issues.
+
+For users that require new features or reliable resolution of reported bugs, we recommend using [pgx](https://github.com/jackc/pgx) which is under active development.

+# Tests
+
+## Running Tests
+
+`go test` is used for testing. A running PostgreSQL
+server is required, with the ability to log in. The
+database to connect to test with is "pqgotest," on
+"localhost" but these can be overridden using [environment
+variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
+
+Example:
+
+	PGHOST=/run/postgresql go test
+
+## Benchmarks
+
+A benchmark suite can be run as part of the tests:
+
+	go test -bench .
+
+## Example setup (Docker)
+
+Run a postgres container:
+
+```
+docker run --expose 5432:5432 postgres
+```
+
+Run tests:
+
+```
+PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
+```

+/*
+Package pq is a pure Go Postgres driver for the database/sql package.
+
+In most cases clients will use the database/sql package instead of
+using this package directly. For example:
+
+	import (
+		"database/sql"
+
+		_ "github.com/lib/pq"
+	)
+
+	func main() {
+		connStr := "user=pqgotest dbname=pqgotest sslmode=verify-full"
+		db, err := sql.Open("postgres", connStr)
+		if err != nil {
+			log.Fatal(err)
+		}
+
+		age := 21
+		rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
+		…
+	}
+
+You can also connect to a database using a URL. For example:
+
+	connStr := "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full"
+	db, err := sql.Open("postgres", connStr)
+
+
+Connection String Parameters
+
+
+Similarly to libpq, when establishing a connection using pq you are expected to
+supply a connection string containing zero or more parameters.
+A subset of the connection parameters supported by libpq are also supported by pq.
+Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
+directly in the connection string.  This is different from libpq, which does not allow
+run-time parameters in the connection string, instead requiring you to supply
+them in the options parameter.
+
+For compatibility with libpq, the following special connection parameters are
+supported:
+
+	* dbname - The name of the database to connect to
+	* user - The user to sign in as
+	* password - The user's password
+	* host - The host to connect to. Values that start with / are for unix
+	  domain sockets. (default is localhost)
+	* port - The port to bind to. (default is 5432)
+	* sslmode - Whether or not to use SSL (default is require, this is not
+	  the default for libpq)
+	* fallback_application_name - An application_name to fall back to if one isn't provided.
+	* connect_timeout - Maximum wait for connection, in seconds. Zero or
+	  not specified means wait indefinitely.
+	* sslcert - Cert file location. The file must contain PEM encoded data.
+	* sslkey - Key file location. The file must contain PEM encoded data.
+	* sslrootcert - The location of the root certificate file. The file
+	  must contain PEM encoded data.
+
+Valid values for sslmode are:
+
+	* disable - No SSL
+	* require - Always SSL (skip verification)
+	* verify-ca - Always SSL (verify that the certificate presented by the
+	  server was signed by a trusted CA)
+	* verify-full - Always SSL (verify that the certification presented by
+	  the server was signed by a trusted CA and the server host name
+	  matches the one in the certificate)
+
+See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
+for more information about connection string parameters.
+
+Use single quotes for values that contain whitespace:
+
+    "user=pqgotest password='with spaces'"
+
+A backslash will escape the next character in values:
+
+    "user=space\ man password='it\'s valid'"
+
+Note that the connection parameter client_encoding (which sets the
+text encoding for the connection) may be set but must be "UTF8",
+matching with the same rules as Postgres. It is an error to provide
+any other value.
+
+In addition to the parameters listed above, any run-time parameter that can be
+set at backend start time can be set in the connection string.  For more
+information, see
+http://www.postgresql.org/docs/current/static/runtime-config.html.
+
+Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
+supported by libpq are also supported by pq.  If any of the environment
+variables not supported by pq are set, pq will panic during connection
+establishment.  Environment variables have a lower precedence than explicitly
+provided connection parameters.
+
+The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
+is supported, but on Windows PGPASSFILE must be specified explicitly.
+
+
+Queries
+
+
+database/sql does not dictate any specific format for parameter
+markers in query strings, and pq uses the Postgres-native ordinal markers,
+as shown above. The same marker can be reused for the same parameter:
+
+	rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
+		OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
+
+pq does not support the LastInsertId() method of the Result type in database/sql.
+To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
+RETURNING clause with a standard Query or QueryRow call:
+
+	var userid int
+	err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
+		VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
+
+For more details on RETURNING, see the Postgres documentation:
+
+	http://www.postgresql.org/docs/current/static/sql-insert.html
+	http://www.postgresql.org/docs/current/static/sql-update.html
+	http://www.postgresql.org/docs/current/static/sql-delete.html
+
+For additional instructions on querying see the documentation for the database/sql package.
+
+
+Data Types
+
+
+Parameters pass through driver.DefaultParameterConverter before they are handled
+by this package. When the binary_parameters connection option is enabled,
+[]byte values are sent directly to the backend as data in binary format.
+
+This package returns the following types for values from the PostgreSQL backend:
+
+	- integer types smallint, integer, and bigint are returned as int64
+	- floating-point types real and double precision are returned as float64
+	- character types char, varchar, and text are returned as string
+	- temporal types date, time, timetz, timestamp, and timestamptz are
+	  returned as time.Time
+	- the boolean type is returned as bool
+	- the bytea type is returned as []byte
+
+All other types are returned directly from the backend as []byte values in text format.
+
+
+Errors
+
+
+pq may return errors of type *pq.Error which can be interrogated for error details:
+
+        if err, ok := err.(*pq.Error); ok {
+            fmt.Println("pq error:", err.Code.Name())
+        }
+
+See the pq.Error type for details.
+
+
+Bulk imports
+
+You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
+pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
+handle can then be repeatedly "executed" to copy data into the target table.
+After all data has been processed you should call Exec() once with no arguments
+to flush all buffered data. Any call to Exec() might return an error which
+should be handled appropriately, but because of the internal buffering an error
+returned by Exec() might not be related to the data passed in the call that
+failed.
+
+CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
+explicit transaction in pq.
+
+Usage example:
+
+	txn, err := db.Begin()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	for _, user := range users {
+		_, err = stmt.Exec(user.Name, int64(user.Age))
+		if err != nil {
+			log.Fatal(err)
+		}
+	}
+
+	_, err = stmt.Exec()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	err = stmt.Close()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	err = txn.Commit()
+	if err != nil {
+		log.Fatal(err)
+	}
+
+
+Notifications
+
+
+PostgreSQL supports a simple publish/subscribe model over database
+connections.  See http://www.postgresql.org/docs/current/static/sql-notify.html
+for more information about the general mechanism.
+
+To start listening for notifications, you first have to open a new connection
+to the database by calling NewListener.  This connection can not be used for
+anything other than LISTEN / NOTIFY.  Calling Listen will open a "notification
+channel"; once a notification channel is open, a notification generated on that
+channel will effect a send on the Listener.Notify channel.  A notification
+channel will remain open until Unlisten is called, though connection loss might
+result in some notifications being lost.  To solve this problem, Listener sends
+a nil pointer over the Notify channel any time the connection is re-established
+following a connection loss.  The application can get information about the
+state of the underlying connection by setting an event callback in the call to
+NewListener.
+
+A single Listener can safely be used from concurrent goroutines, which means
+that there is often no need to create more than one Listener in your
+application.  However, a Listener is always connected to a single database, so
+you will need to create a new Listener instance for every database you want to
+receive notifications in.
+
+The channel name in both Listen and Unlisten is case sensitive, and can contain
+any characters legal in an identifier (see
+http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
+for more information).  Note that the channel name will be truncated to 63
+bytes by the PostgreSQL server.
+
+You can find a complete, working example of Listener usage at
+https://godoc.org/github.com/lib/pq/example/listen.
+
+
+Kerberos Support
+
+
+If you need support for Kerberos authentication, add the following to your main
+package:
+
+	import "github.com/lib/pq/auth/kerberos"
+
+	func init() {
+		pq.RegisterGSSProvider(func() (pq.Gss, error) { return kerberos.NewGSS() })
+	}
+
+This package is in a separate module so that users who don't need Kerberos
+don't have to download unnecessary dependencies.
+
+When imported, additional connection string parameters are supported:
+
+	* krbsrvname - GSS (Kerberos) service name when constructing the
+	  SPN (default is `postgres`). This will be combined with the host
+	  to form the full SPN: `krbsrvname/host`.
+	* krbspn - GSS (Kerberos) SPN. This takes priority over
+	  `krbsrvname` if present.

+Colorable writer for windows.
+
+For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
+This package is possible to handle escape sequence for ansi color on windows.
+
+## Too Bad!
+

+
+
+## So Good!
+
+![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
+
+## Usage
+
+```go
+logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
+logrus.SetOutput(colorable.NewColorableStdout())
+
+logrus.Info("succeeded")
+logrus.Warn("not correct")
+logrus.Error("something error")
+logrus.Fatal("panic")
+```
+
+You can compile above code on non-windows OSs.
+

+
+# Installation
+
+This package can be installed with the `go get` command:
+
+    go get github.com/mattn/go-sqlite3
+
+_go-sqlite3_ is *cgo* package.
+If you want to build your app using go-sqlite3, you need gcc.
+However, after you have built and installed _go-sqlite3_ with `go install github.com/mattn/go-sqlite3` (which requires gcc), you can build your app without relying on gcc in future.
+
+***Important: because this is a `CGO` enabled package, you are required to set the environment variable `CGO_ENABLED=1` and have a `gcc` compile present within your path.***
+
+# API Reference
+
+API documentation can be found [here](http://godoc.org/github.com/mattn/go-sqlite3).
+
+Examples can be found under the [examples](./_example) directory.
+
+# Connection String
+
+When creating a new SQLite database or connection to an existing one, with the file name additional options can be given.
+This is also known as a DSN (Data Source Name) string.
+
+Options are append after the filename of the SQLite database.
+The database filename and options are separated by an `?` (Question Mark).
+Options should be URL-encoded (see [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)).
+
+This also applies when using an in-memory database instead of a file.
+
+Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
+
+This library supports DSN options of SQLite itself and provides additional options.
+
+Boolean values can be one of:
+* `0` `no` `false` `off`
+* `1` `yes` `true` `on`

+
+# Features
+
+This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build `tags`.
+
+Click [here](https://golang.org/pkg/go/build/#hdr-Build_Constraints) for more information about build tags / constraints.
+
+### Usage
+
+If you wish to build this library with additional extensions / features, use the following command:
+
+```bash
+go build --tags "<FEATURE>"
+```
+
+For available features, see the extension list.
+When using multiple build tags, all the different tags should be space delimited.
+
+Example:
+
+```bash
+go build --tags "icu json1 fts5 secure_delete"
+```
+
+### Feature / Extension List
+
+| Extension | Build Tag | Description |
+|-----------|-----------|-------------|
+| Additional Statistics | sqlite_stat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.<br><br>The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |
+| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or "localhost".<br><br>However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way |
+| App Armor | sqlite_app_armor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. <br><br>App Armor is not available under `Windows`. |
+| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.<br><br>To disable extension loading add the build tag `sqlite_omit_load_extension`. |
+| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.<br><br>Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.<br><br>Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default | 
+| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |
+| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |
+| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |
+|  International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build |
+| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. <ul><li>PRAGMA function_list</li><li>PRAGMA module_list</li><li>PRAGMA pragma_list</li></ul> |
+| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |
+| Math Functions | sqlite_math_functions | This compile-time option enables built-in scalar math functions. For more information see [Built-In Mathematical SQL Functions](https://www.sqlite.org/lang_mathfunc.html) |
+| OS Trace | sqlite_os_trace | This option enables OSTRACE() debug logging. This can be verbose and should not be used in production. |
+| Pre Update Hook | sqlite_preupdate_hook | Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table. |
+| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.<br><br>When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.<br><br>The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.<br><br>On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information |
+| Secure Delete (FAST) | sqlite_secure_delete_fast | For more information see [PRAGMA secure_delete](https://www.sqlite.org/pragma.html#pragma_secure_delete) |
+| Tracing / Debug | sqlite_trace | Activate trace functions |
+| User Authentication | sqlite_userauth | SQLite User Authentication see [User Authentication](#user-authentication) for more information. |
+| Virtual Tables | sqlite_vtable | SQLite Virtual Tables see [SQLite Official VTABLE Documentation](https://www.sqlite.org/vtab.html) for more information, and a [full example here](https://github.com/mattn/go-sqlite3/tree/master/_example/vtable) |
+

+## Errors
+
+- Compile error: `can not be used when making a shared object; recompile with -fPIC`
+
+    When receiving a compile time error referencing recompile with `-FPIC` then you
+    are probably using a hardend system.
+
+    You can compile the library on a hardend system with the following command.
+
+    ```bash
+    go build -ldflags '-extldflags=-fno-PIC'
+    ```
+
+    More details see [#120](https://github.com/mattn/go-sqlite3/issues/120)
+
+- Can't build go-sqlite3 on windows 64bit.
+
+    > Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
+    > See: [#27](https://github.com/mattn/go-sqlite3/issues/27)
+
+- `go get github.com/mattn/go-sqlite3` throws compilation error.

+
+# User Authentication
+
+This package supports the SQLite User Authentication module.
+
+## Compile
+
+To use the User authentication module, the package has to be compiled with the tag `sqlite_userauth`. See [Features](#features).
+
+## Usage
+
+### Create protected database
+
+To create a database protected by user authentication, provide the following argument to the connection string `_auth`.
+This will enable user authentication within the database. This option however requires two additional arguments:
+
+- `_auth_user`
+- `_auth_pass`
+
+When `_auth` is present in the connection string user authentication will be enabled and the provided user will be created
+as an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.
+
+Example connection strings:
+
+Create an user authentication database with user `admin` and password `admin`:
+
+`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin`
+
+Create an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding:
+
+`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1`
+
+### Password Encoding
+
+The passwords within the user authentication module of SQLite are encoded with the SQLite function `sqlite_cryp`.
+This function uses a ceasar-cypher which is quite insecure.
+This library provides several additional password encoders which can be configured through the connection string.
+
+The password cypher can be configured with the key `_auth_crypt`. And if the configured password encoder also requires an
+salt this can be configured with `_auth_salt`.
+
+#### Available Encoders
+
+- SHA1
+- SSHA1 (Salted SHA1)
+- SHA256
+- SSHA256 (salted SHA256)
+- SHA384
+- SSHA384 (salted SHA384)
+- SHA512
+- SSHA512 (salted SHA512)
+
+### Restrictions
+
+Operations on the database regarding user management can only be preformed by an administrator user.
+
+### Support
+
+The user authentication supports two kinds of users:
+
+- administrators
+- regular users
+
+### User Management
+
+User management can be done by directly using the `*SQLiteConn` or by SQL.
+
+#### SQL
+
+The following sql functions are available for user management:
+
+| Function | Arguments | Description |
+|----------|-----------|-------------|
+| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |
+| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.<br>if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |
+| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |
+| `authUserDelete` | username `string` | Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |
+
+These functions will return an integer:
+
+- 0 (SQLITE_OK)
+- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges
+
+##### Examples
+
+```sql
+// Autheticate user
+// Create Admin User
+SELECT auth_user_add('admin2', 'admin2', 1);
+
+// Change password for user
+SELECT auth_user_change('user', 'userpassword', 0);
+
+// Delete user
+SELECT user_delete('user');
+```
+
+#### *SQLiteConn
+
+The following functions are available for User authentication from the `*SQLiteConn`:
+
+| Function | Description |
+|----------|-------------|
+| `Authenticate(username, password string) error` | Authenticate user |
+| `AuthUserAdd(username, password string, admin bool) error` | Add user |
+| `AuthUserChange(username, password string, admin bool) error` | Modify user |
+| `AuthUserDelete(username string) error` | Delete user |
+
+### Attached database
+
+When using attached databases, SQLite will use the authentication from the `main` database for the attached database(s).
+
+# Extensions
+
+If you want your own extension to be listed here, or you want to add a reference to an extension; please submit an Issue for this.
+
+## Spatialite
+
+Spatialite is available as an extension to SQLite, and can be used in combination with this repository.
+For an example, see [shaxbee/go-spatialite](https://github.com/shaxbee/go-spatialite).
+
+## extension-functions.c from SQLite3 Contrib
+
+extension-functions.c is available as an extension to SQLite, and provides the following functions:
+
+- Math: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, log, log10, power, sign, sqrt, square, ceil, floor, pi.
+- String: replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim, replace, reverse, proper, padl, padr, padc, strfilter.
+- Aggregate: stdev, variance, mode, median, lower_quartile, upper_quartile
+
+For an example, see [dinedal/go-sqlite3-extension-functions](https://github.com/dinedal/go-sqlite3-extension-functions).
+
+# FAQ
+
+- Getting insert error while query is opened.
+
+    > You can pass some arguments into the connection string, for example, a URI.
+    > See: [#39](https://github.com/mattn/go-sqlite3/issues/39)
+
+- Do you want to cross compile? mingw on Linux or Mac?
+
+    > See: [#106](https://github.com/mattn/go-sqlite3/issues/106)
+    > See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
+
+- Want to get time.Time with current locale
+
+    Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.
+
+- Can I use this in multiple routines concurrently?
+
+    Yes for readonly. But not for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).
+
+- Why I'm getting `no such table` error?
+
+    Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
+
+    Each connection to `":memory:"` opens a brand new in-memory sql database, so if
+    the stdlib's sql engine happens to open another connection and you've only
+    specified `":memory:"`, that connection will see a brand new database. A
+    workaround is to use `"file::memory:?cache=shared"` (or `"file:foobar?mode=memory&cache=shared"`). Every
+    connection to this string will point to the same in-memory database.
+    
+    Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the [max idle connection limit](https://golang.org/pkg/database/sql/#DB.SetMaxIdleConns) is > 0, and the [connection lifetime](https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime) is infinite.
+

+
+- Reading from database with large amount of goroutines fails on OSX.
+
+    OS X limits OS-wide to not have more than 1000 files open simultaneously by default.
+
+    For more information, see [#289](https://github.com/mattn/go-sqlite3/issues/289)
+
+- Trying to execute a `.` (dot) command throws an error.
+
+    Error: `Error: near ".": syntax error`
+    Dot command are part of SQLite3 CLI, not of this library.
+
+    You need to implement the feature or call the sqlite3 cli.
+
+    More information see [#305](https://github.com/mattn/go-sqlite3/issues/305).
+
+- Error: `database is locked`
+
+    When you get a database is locked, please use the following options.
+
+    Add to DSN: `cache=shared`
+
+    Example:
+    ```go
+    db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
+    ```
+
+    Next, please set the database connections of the SQL package to 1:
+    
+    ```go
+    db.SetMaxOpenConns(1)
+    ```
+
+    For more information, see [#209](https://github.com/mattn/go-sqlite3/issues/209).

+Package sqlite3 provides interface to SQLite3 databases.
+
+This works as a driver for database/sql.
+
+Installation
+
+    go get github.com/mattn/go-sqlite3
+
+Supported Types
+
+Currently, go-sqlite3 supports the following data types.
+
+    +------------------------------+
+    |go        | sqlite3           |
+    |----------|-------------------|
+    |nil       | null              |
+    |int       | integer           |
+    |int64     | integer           |
+    |float64   | float             |
+    |bool      | integer           |
+    |[]byte    | blob              |
+    |string    | text              |
+    |time.Time | timestamp/datetime|
+    +------------------------------+
+
+SQLite3 Extension
+
+You can write your own extension module for sqlite3. For example, below is an
+extension for a Regexp matcher operation.
+
+    #include <pcre.h>
+    #include <string.h>
+    #include <stdio.h>
+    #include <sqlite3ext.h>
+
+    SQLITE_EXTENSION_INIT1
+    static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
+      if (argc >= 2) {
+        const char *target  = (const char *)sqlite3_value_text(argv[1]);
+        const char *pattern = (const char *)sqlite3_value_text(argv[0]);
+        const char* errstr = NULL;
+        int erroff = 0;
+        int vec[500];
+        int n, rc;
+        pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
+        rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
+        if (rc <= 0) {
+          sqlite3_result_error(context, errstr, 0);
+          return;
+        }
+        sqlite3_result_int(context, 1);
+      }
+    }
+
+    #ifdef _WIN32
+    __declspec(dllexport)
+    #endif
+    int sqlite3_extension_init(sqlite3 *db, char **errmsg,
+          const sqlite3_api_routines *api) {
+      SQLITE_EXTENSION_INIT2(api);
+      return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
+          (void*)db, regexp_func, NULL, NULL);
+    }
+
+It needs to be built as a so/dll shared library. And you need to register
+the extension module like below.
+
+	sql.Register("sqlite3_with_extensions",
+		&sqlite3.SQLiteDriver{
+			Extensions: []string{
+				"sqlite3_mod_regexp",
+			},
+		})
+
+Then, you can use this extension.
+
+	rows, err := db.Query("select text from mytable where name regexp '^golang'")
+
+Connection Hook
+
+You can hook and inject your code when the connection is established by setting
+ConnectHook to get the SQLiteConn.
+
+	sql.Register("sqlite3_with_hook_example",
+			&sqlite3.SQLiteDriver{
+					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
+						sqlite3conn = append(sqlite3conn, conn)
+						return nil
+					},
+			})
+
+You can also use database/sql.Conn.Raw (Go >= 1.13):
+
+	conn, err := db.Conn(context.Background())
+	// if err != nil { ... }
+	defer conn.Close()
+	err = conn.Raw(func (driverConn interface{}) error {
+		sqliteConn := driverConn.(*sqlite3.SQLiteConn)
+		// ... use sqliteConn
+	})
+	// if err != nil { ... }
+
+Go SQlite3 Extensions
+
+If you want to register Go functions as SQLite extension functions
+you can make a custom driver by calling RegisterFunction from
+ConnectHook.
+
+	regex = func(re, s string) (bool, error) {
+		return regexp.MatchString(re, s)
+	}
+	sql.Register("sqlite3_extended",
+			&sqlite3.SQLiteDriver{
+					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
+						return conn.RegisterFunc("regexp", regex, true)
+					},
+			})
+
+You can then use the custom driver by passing its name to sql.Open.
+
+	var i int
+	conn, err := sql.Open("sqlite3_extended", "./foo.db")
+	if err != nil {

+** This object defines the methods used to perform various operations
+** against the open file represented by the [sqlite3_file] object.

+** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
+** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
+** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
+** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
+** to NULL.
+**
+** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
+** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
+** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
+** flag may be ORed in to indicate that only the data of the file
+** and not its inode needs to be synced.
+**
+** The integer values to xLock() and xUnlock() are one of
+** <ul>
+** <li> [SQLITE_LOCK_NONE],
+** <li> [SQLITE_LOCK_SHARED],
+** <li> [SQLITE_LOCK_RESERVED],
+** <li> [SQLITE_LOCK_PENDING], or
+** <li> [SQLITE_LOCK_EXCLUSIVE].
+** </ul>
+** xLock() increases the lock. xUnlock() decreases the lock.
+** The xCheckReservedLock() method checks whether any database connection,
+** either in this process or in some other process, is holding a RESERVED,
+** PENDING, or EXCLUSIVE lock on the file.  It returns true
+** if such a lock exists and false otherwise.
+**
+** The xFileControl() method is a generic interface that allows custom
+** VFS implementations to directly control an open file using the
+** [sqlite3_file_control()] interface.  The second "op" argument is an
+** integer opcode.  The third argument is a generic pointer intended to
+** point to a structure that may contain arguments or space in which to
+** write return values.  Potential uses for xFileControl() might be
+** functions to enable blocking locks with timeouts, to change the
+** locking strategy (for example to use dot-file locks), to inquire
+** about the status of a lock, or to break stale locks.  The SQLite
+** core reserves all opcodes less than 100 for its own use.
+** A [file control opcodes | list of opcodes] less than 100 is available.
+** Applications that define a custom xFileControl method should use opcodes
+** greater than 100 to avoid conflicts.  VFS implementations should
+** return [SQLITE_NOTFOUND] for file control opcodes that they do not
+** recognize.
+**
+** The xSectorSize() method returns the sector size of the

+** The SQLITE_IOCAP_ATOMIC property means that all writes of

+** way around.  The SQLITE_IOCAP_SEQUENTIAL property means that
+** information is written to disk in the same order as calls
+** to xWrite().
+**
+** If xRead() returns SQLITE_IOERR_SHORT_READ it must also fill

+** CAPI3REF: Standard File Control Opcodes
+** KEYWORDS: {file control opcodes} {file control opcode}
+**
+** These integer constants are opcodes for the xFileControl method
+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
+** interface.
+**
+** <ul>
+** <li>[[SQLITE_FCNTL_LOCKSTATE]]
+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and is only available when the SQLITE_TEST
+** compile-time option is used.
+**
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction.  This hint is not guaranteed to be accurate but it
+** is often close.  The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
+** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
+** implements [sqlite3_deserialize()] to set an upper bound on the size
+** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
+** If the integer pointed to is negative, then it is filled in with the
+** current limit.  Otherwise the limit is set to the larger of the value
+** of the integer pointed to and the current database size.  The integer
+** pointed to is set to the new limit.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
+**
+** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
+** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with the journal file (either
+** the [rollback journal] or the [write-ahead log]) for a particular database
+** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** No longer in use.
+**
+** <li>[[SQLITE_FCNTL_SYNC]]
+** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
+** sent to the VFS immediately before the xSync method is invoked on a
+** database file descriptor. Or, if the xSync method is not invoked
+** because the user has configured SQLite with
+** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
+** of the xSync method. In most cases, the pointer argument passed with
+** this file-control is NULL. However, if the database file is being synced
+** as part of a multi-database commit, the argument points to a nul-terminated
+** string containing the transactions super-journal file name. VFSes that
+** do not need this signal should silently ignore this opcode. Applications
+** should not call [sqlite3_file_control()] with this opcode as doing so may
+** disrupt the operation of the specialized VFSes that do require it.
+**
+** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
+** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
+** and sent to the VFS after a transaction has been committed immediately
+** but before the database is unlocked. VFSes that do not need this signal
+** should silently ignore this opcode. Applications should not call
+** [sqlite3_file_control()] with this opcode as doing so may disrupt the
+** operation of the specialized VFSes that do require it.
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs.  By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry.  This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted.  The values are changed for all database connections
+** within the same process.  The argument is a pointer to an array of two
+** integers where the first integer is the new retry count and the second
+** integer is the delay.  If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated.  The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
+** write ahead log ([WAL file]) and shared memory
+** files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes.  Setting persistent WAL mode causes those files to persist after
+** close.  Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable.  The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode.  If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode.  If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done.  As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything.  Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented.  This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_VFS_POINTER]]
+** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
+** [VFSes] currently in use.  ^(The argument X in
+** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
+** of type "[sqlite3_vfs] **".  This opcodes will set *X
+** to a pointer to the top-level VFS.)^
+** ^When there are multiple VFS shims in the stack, this opcode finds the
+** upper-most shim only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument.  ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
+** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement if result string is NULL, or that returns a copy
+** of the result string if the string is non-NULL.
+** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connection's busy-handler callback. The argument is of type (void**)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connection's
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses.  The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()].  The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map.  The
+** pointer is overwritten with the old value.  The limit is not changed if
+** the value originally pointed to is negative, and so the current limit
+** can be queried by passing in a pointer to a negative number.  This
+** file-control is used internally to implement [PRAGMA mmap_size].
+**
+** <li>[[SQLITE_FCNTL_TRACE]]
+** The [SQLITE_FCNTL_TRACE] file control provides advisory information
+** to the VFS about what the higher layers of the SQLite stack are doing.
+** This file control is used by some VFS activity tracing [shims].
+** The argument is a zero-terminated string.  Higher layers in the
+** SQLite stack may generate instances of this file control if
+** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
+**
+** <li>[[SQLITE_FCNTL_HAS_MOVED]]
+** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
+** pointer to an integer and it writes a boolean into that integer depending
+** on whether or not the file has been renamed, moved, or deleted since it
+** was first opened.
+**
+** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
+** underlying native file handle associated with a file handle.  This file
+** control interprets its argument as a pointer to a native file handle and
+** writes the resulting value there.
+**
+** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to swap the file handle with the one
+** pointed to by the pArg argument.  This capability is used during testing
+** and only needs to be supported when SQLITE_TEST is defined.
+**
+** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
+** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
+** be advantageous to block on the next WAL lock if the lock is not immediately
+** available.  The WAL subsystem issues this signal during rare
+** circumstances in order to fix a problem with priority inversion.
+** Applications should <em>not</em> use this file-control.
+**
+** <li>[[SQLITE_FCNTL_ZIPVFS]]
+** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
+** VFS should return SQLITE_NOTFOUND for this opcode.
+**
+** <li>[[SQLITE_FCNTL_RBU]]
+** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
+** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
+** this opcode.
+**
+** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
+** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
+** the file descriptor is placed in "batch write mode", which
+** means all subsequent write operations will be deferred and done
+** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
+** that do not support batch atomic writes will return SQLITE_NOTFOUND.
+** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
+** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
+** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
+** no VFS interface calls on the same [sqlite3_file] file descriptor
+** except for calls to the xWrite method and the xFileControl method
+** with [SQLITE_FCNTL_SIZE_HINT].
+**
+** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
+** This file control returns [SQLITE_OK] if and only if the writes were
+** all performed successfully and have been committed to persistent storage.
+** ^Regardless of whether or not it is successful, this file control takes
+** the file descriptor out of batch write mode so that all subsequent
+** write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
+** ^This file control takes the file descriptor out of batch write mode
+** so that all subsequent write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
+** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
+** to block for up to M milliseconds before failing when attempting to
+** obtain a file lock using the xLock or xShmLock methods of the VFS.
+** The parameter is a pointer to a 32-bit signed integer that contains
+** the value that M is to be set to. Before returning, the 32-bit signed
+** integer is overwritten with the previous value of M.
+**
+** <li>[[SQLITE_FCNTL_DATA_VERSION]]
+** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
+** a database file.  The argument is a pointer to a 32-bit unsigned integer.
+** The "data version" for the pager is written into the pointer.  The
+** "data version" changes whenever any change occurs to the corresponding
+** database file, either through SQL statements on the same database
+** connection or through transactions committed by separate database
+** connections possibly in other processes. The [sqlite3_total_changes()]
+** interface can be used to find if any database on the connection has changed,
+** but that interface responds to changes on TEMP as well as MAIN and does
+** not provide a mechanism to detect changes to MAIN only.  Also, the
+** [sqlite3_total_changes()] interface responds to internal changes only and
+** omits changes made by other database connections.  The
+** [PRAGMA data_version] command provides a mechanism to detect changes to
+** a single attached database that occur due to other database connections,
+** but omits changes implemented by the database connection on which it is
+** called.  This file control is the only mechanism to detect changes that
+** happen either internally or externally and that are associated with
+** a particular attached database.
+**
+** <li>[[SQLITE_FCNTL_CKPT_START]]
+** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
+** in wal mode before the client starts to copy pages from the wal
+** file to the database file.
+**
+** <li>[[SQLITE_FCNTL_CKPT_DONE]]
+** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
+** in wal mode after the client has finished copying pages from the wal
+** file to the database file, but before the *-shm file is updated to
+** record the fact that the pages have been checkpointed.
+** </ul>
+**
+** <li>[[SQLITE_FCNTL_EXTERNAL_READER]]
+** The EXPERIMENTAL [SQLITE_FCNTL_EXTERNAL_READER] opcode is used to detect
+** whether or not there is a database client in another process with a wal-mode
+** transaction open on the database or not. It is only available on unix.The
+** (void*) argument passed with this file-control should be a pointer to a
+** value of type (int). The integer value is set to 1 if the database is a wal
+** mode database and there exists at least one client in another process that
+** currently has an SQL transaction open on the database. It is set to 0 if
+** the database is not a wal-mode db, or if there is no such connection in any
+** other process. This opcode cannot be used to detect transactions opened
+** by clients within the current process, only within other processes.
+** </ul>
+**
+** <li>[[SQLITE_FCNTL_CKSM_FILE]]
+** Used by the cksmvfs VFS module only.

+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system.  The "vfs"
+** in the name of the object stands for "virtual file system".  See
+** the [VFS | VFS documentation] for further information.
+**
+** The VFS interface is sometimes extended by adding new methods onto
+** the end.  Each time such an extension occurs, the iVersion field
+** is incremented.  The iVersion value started out as 1 in
+** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
+** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
+** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
+** may be appended to the sqlite3_vfs object and the iVersion value
+** may increase again in future versions of SQLite.
+** Note that due to an oversight, the structure
+** of the sqlite3_vfs object changed in the transition from
+** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
+** and yet the iVersion field was not increased.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS.  mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer.  The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way.  The [sqlite3_vfs_find()] interface
+** searches the list.  Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify.  SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module.  The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file.  ^Whenever the
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()
+** call, depending on the object being opened:
+**
+** <ul>
+** <li>  [SQLITE_OPEN_MAIN_DB]
+** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
+** <li>  [SQLITE_OPEN_TEMP_DB]
+** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
+** <li>  [SQLITE_OPEN_TRANSIENT_DB]
+** <li>  [SQLITE_OPEN_SUBJOURNAL]
+** <li>  [SQLITE_OPEN_SUPER_JOURNAL]
+** <li>  [SQLITE_OPEN_WAL]
+** </ul>)^
+**
+** The file I/O implementation can use the object type flags to
+** change the way it deals with files.  For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op.  Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR.  Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen.  The xOpen method does not have to
+** allocate the structure; it should just fill it in.  Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
+** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
+** flag is never actually used and is not implemented in the built-in
+** VFSes of SQLite.  The file is named by the second argument and can be a
+** directory. The xAccess method returns [SQLITE_OK] on success or some
+** non-zero error code if there is an I/O error or if the name of
+** the file given in the second argument is illegal.  If SQLITE_OK
+** is returned, then non-zero or zero is written into *pResOut to indicate
+** whether or not the file is accessible.
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname.  The exact size of the output buffer
+** is also passed as a parameter to both  methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut.  The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given.  ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in
+** a 24-hour day).
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core.  These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce.  The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next.  Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next.  Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
+**
+** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
+** is not.  The sqlite3_shutdown() interface must only be called from a
+** single thread.  All open [database connections] must be closed and all
+** other SQLite resources must be deallocated prior to invoking
+** sqlite3_shutdown().
+**
+** Among other things, ^sqlite3_initialize() will invoke

+**
+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** ^If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically

+** are omitted and the application must call sqlite3_initialize() directly
+** prior to using any other SQLite interface.  For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface.  Future releases
+** of SQLite may require this.  In other words, the behavior exhibited
+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific

+**
+** Note that SQLite comes with several [built-in memory allocators]
+** that are perfectly adequate for the overwhelming majority of applications
+** and that this object is only useful to a tiny minority of applications
+** with specialized memory allocation requirements.  This object is
+** also used during testing of SQLite in order to specify an alternative
+** memory allocator that simulates memory out-of-memory conditions in
+** order to verify that SQLite recovers gracefully from such
+** conditions.
+**
+** The xMalloc, xRealloc, and xFree methods must work like the
+** malloc(), realloc() and free() functions from the standard C library.
+** ^SQLite guarantees that the second argument to
+** xRealloc is always a value returned by a prior call to xRoundup.
+**
+** xSize should return the allocated size of a memory allocation
+** previously obtained from xMalloc or xRealloc.  The allocated size
+** is always at least as big as the requested size but may be larger.
+**
+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size.  Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8.  Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0,
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator.  For example,

+** CAPI3REF: Convenience Routines For Running Queries
+** METHOD: sqlite3
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface.  A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns.  But
+** these numbers are not part of the result table itself.  These
+** numbers are obtained separately.  Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array.  The first M pointers point
+** to zero-terminated strings that  contain the names of the columns.
+** The remaining entries all point to query results.  NULL values result
+** in NULL pointers.  All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+**        Name        | Age
+**        -----------------------
+**        Alice       | 43
+**        Bob         | 28
+**        Cindy       | 21
+** </pre></blockquote>
+**
+** There are two columns (M==2) and three rows (N==3).  Thus the
+** result table has 8 entries.  Suppose the result table is stored
+** in an array named azResult.  Then azResult holds this content:
+**
+** <blockquote><pre>
+**        azResult&#91;0] = "Name";
+**        azResult&#91;1] = "Age";
+**        azResult&#91;2] = "Alice";
+**        azResult&#91;3] = "43";
+**        azResult&#91;4] = "Bob";
+**        azResult&#91;5] = "28";
+**        azResult&#91;6] = "Cindy";
+**        azResult&#91;7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**
+** After the application has finished with the result from sqlite3_get_table(),
+** it must pass the result table pointer to sqlite3_free_table() in order to
+** release the memory that was malloced.  Because of the way the
+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly.  Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around
+** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite.  It uses only the public
+** interface defined here.  As a consequence, errors that occur in the
+** wrapper layer outside of the internal [sqlite3_exec()] call are not
+** reflected in subsequent calls to [sqlite3_errcode()] or
+** [sqlite3_errmsg()].

+**

+** Memory corruption, a segmentation fault, or other severe error

+** ^If the X parameter to sqlite3_realloc(X,N)
+** is a NULL pointer then its behavior is identical to calling

+** ^If M is the size of the prior allocation, then min(N,M) bytes

+** METHOD: sqlite3
+** KEYWORDS: {authorizer callback}
+**
+** ^This routine registers an authorizer callback with a particular

+** ^The authorizer callback is invoked as SQL statements are being compiled
+** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
+** [sqlite3_prepare_v3()], [sqlite3_prepare16()], [sqlite3_prepare16_v2()],
+** and [sqlite3_prepare16_v3()].  ^At various
+** points during the compilation process, as logic is being created
+** to perform various actions, the authorizer callback is invoked to
+** see if those actions are allowed.  ^The authorizer callback should
+** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
+** specific action but allow the SQL statement to continue to be
+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
+** rejected with an error.  ^If the authorizer callback returns
+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
+** then the [sqlite3_prepare_v2()] or equivalent call that triggered
+** the authorizer will fail with an error message.
+**
+** When the callback returns [SQLITE_OK], that means the operation
+** requested is ok.  ^When the callback returns [SQLITE_DENY], the
+** [sqlite3_prepare_v2()] or equivalent call that triggered the
+** authorizer will fail with an error message explaining that
+** access is denied.
+**
+** ^The first parameter to the authorizer callback is a copy of the third
+** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. ^The third through sixth parameters
+** to the callback are either NULL pointers or zero-terminated strings
+** that contain additional details about the action to be authorized.
+** Applications must always be prepared to encounter a NULL pointer in any
+** of the third through the sixth parameters of the authorization callback.
+**
+** ^If the action code is [SQLITE_READ]
+** and the callback returns [SQLITE_IGNORE] then the
+** [prepared statement] statement is constructed to substitute
+** a NULL value in place of the table column that would have
+** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
+** return can be used to deny an untrusted user access to individual
+** columns of a table.
+** ^When a table is referenced by a [SELECT] but no column values are
+** extracted from that table (for example in a query like
+** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
+** is invoked once for that table with a column name that is an empty string.
+** ^If the action code is [SQLITE_DELETE] and the callback returns
+** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
+** [truncate optimization] is disabled and all rows are deleted individually.
+**
+** An authorizer is used when [sqlite3_prepare | preparing]
+** SQL statements from an untrusted source, to ensure that the SQL statements
+** do not try to access data they are not allowed to see, or that they do not
+** try to execute malicious statements that damage the database.  For
+** example, an application may allow a user to enter arbitrary
+** SQL queries for evaluation by a database.  But the application does
+** not want the user to be able to make arbitrary changes to the
+** database.  An authorizer could then be put in place while the
+** user-entered SQL is being [sqlite3_prepare | prepared] that
+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources
+** might also consider lowering resource limits using [sqlite3_limit()]
+** and limiting database size using the [max_page_count] [PRAGMA]
+** in addition to using an authorizer.
+**
+** ^(Only a single authorizer can be in place on a database connection

+**
+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument
+** begins with "file:", then the filename is interpreted as a URI. ^URI
+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the third argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default.  See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string
+** "localhost". ^If the authority is not an empty string or "localhost", an
+** error is returned to the caller. ^The fragment component of a URI, if
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character,
+** then it is interpreted as an absolute path. ^If the path does not begin
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path.
+** ^(On windows, the first component of an absolute path
+** is a drive specification (e.g. "C:").)^
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite and its built-in [VFSes] interpret the
+** following query parameters:
+**
+** <ul>
+**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+**     a VFS object that provides the operating system interface that should
+**     be used to access the database file on disk. ^If this option is set to
+**     an empty string the default VFS object is used. ^Specifying an unknown
+**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+**     present, then the VFS specified by the option takes precedence over
+**     the value passed as the fourth parameter to sqlite3_open_v2().
+**
+**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+**     "rwc", or "memory". Attempting to set it to any other value is
+**     an error)^.
+**     ^If "ro" is specified, then the database is opened for read-only
+**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
+**     third argument to sqlite3_open_v2(). ^If the mode option is set to
+**     "rw", then the database is opened for read-write (but not create)
+**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
+**     been set. ^Value "rwc" is equivalent to setting both
+**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
+**     set to "memory" then a pure [in-memory database] that never reads
+**     or writes from disk is used. ^It is an error to specify a value for
+**     the mode parameter that is less restrictive than that specified by
+**     the flags passed in the third parameter to sqlite3_open_v2().
+**
+**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+**     "private". ^Setting it to "shared" is equivalent to setting the
+**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is
+**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+**     a URI filename, its value overrides any behavior requested by setting
+**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+**
+**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
+**     [powersafe overwrite] property does or does not apply to the
+**     storage media on which the database file resides.
+**
+**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
+**     which if set disables file locking in rollback journal modes.  This
+**     is useful for accessing a database on a filesystem that does not
+**     support locking.  Caution:  Database corruption might result if two
+**     or more processes write to the same database and any one of those
+**     processes uses nolock=1.
+**
+**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
+**     parameter that indicates that the database file is stored on
+**     read-only media.  ^When immutable is set, SQLite assumes that the
+**     database file cannot be changed, even by a process with higher
+**     privilege, and so the database is opened read-only and all locking
+**     and change detection is disabled.  Caution: Setting the immutable
+**     property on a database file that does in fact change can result
+**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
+**     See also: [SQLITE_IOCAP_IMMUTABLE].
+**
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error.  Future versions of SQLite might understand additional query
+** parameters.  See "[query parameters with special meaning to SQLite]" for
+** additional information.

+**
+** These are utility routines, useful to [VFS|custom VFS implementations],
+** that check if a database file was a URI that contained a specific query
+** parameter, and if so obtains the value of that query parameter.
+**
+** The first parameter to these interfaces (hereafter referred to
+** as F) must be one of:
+** <ul>
+** <li> A database filename pointer created by the SQLite core and
+** passed into the xOpen() method of a VFS implemention, or
+** <li> A filename obtained from [sqlite3_db_filename()], or
+** <li> A new filename constructed using [sqlite3_create_filename()].
+** </ul>
+** If the F parameter is not one of the above, then the behavior is
+** undefined and probably undesirable.  Older versions of SQLite were
+** more tolerant of invalid F parameters than newer versions.
+**
+** If F is a suitable filename (as described in the previous paragraph)
+** and if P is the name of the query parameter, then
+** sqlite3_uri_parameter(F,P) returns the value of the P
+** parameter if it exists or a NULL pointer if P does not appear as a
+** query parameter on F.  If P is a query parameter of F and it
+** has no explicit value, then sqlite3_uri_parameter(F,P) returns
+** a pointer to an empty string.
+**
+** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
+** parameter and returns true (1) or false (0) according to the value
+** of P.  The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
+** value of query parameter P is one of "yes", "true", or "on" in any
+** case or if the value begins with a non-zero number.  The
+** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
+** query parameter P is one of "no", "false", or "off" in any case or
+** if the value begins with a numeric zero.  If P is not a query
+** parameter on F or if the value of P does not match any of the
+** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
+**
+** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
+** 64-bit signed integer and returns that integer, or D if P does not
+** exist.  If the value of P is something other than an integer, then
+** zero is returned.
+**
+** The sqlite3_uri_key(F,N) returns a pointer to the name (not
+** the value) of the N-th query parameter for filename F, or a NULL
+** pointer if N is less than zero or greater than the number of query
+** parameters minus 1.  The N value is zero-based so N should be 0 to obtain
+** the name of the first query parameter, 1 for the second parameter, and
+** so forth.
+**
+** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
+** sqlite3_uri_boolean(F,P,B) returns B.  If F is not a NULL pointer and
+** is not a database file pathname pointer that the SQLite core passed
+** into the xOpen VFS method, then the behavior of this routine is undefined
+** and probably undesirable.
+**
+** Beginning with SQLite [version 3.31.0] ([dateof:3.31.0]) the input F
+** parameter can also be the name of a rollback journal file or WAL file
+** in addition to the main database file.  Prior to version 3.31.0, these
+** routines would only work if F was the name of the main database file.
+** When the F parameter is the name of the rollback journal or WAL file,

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+** METHOD: sqlite3
+** CONSTRUCTOR: sqlite3_stmt
+**
+** To execute an SQL statement, it must first be compiled into a byte-code
+** program using one of these routines.  Or, in other words, these routines
+** are constructors for the [prepared statement] object.
+**
+** The preferred routine to use is [sqlite3_prepare_v2()].  The
+** [sqlite3_prepare()] interface is legacy and should be avoided.
+** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
+** for special purposes.
+**
+** The use of the UTF-8 interfaces is preferred, as SQLite currently
+** does all parsing using UTF-8.  The UTF-16 interfaces are provided
+** as a convenience.  The UTF-16 interfaces work by converting the
+** input text into UTF-8, then invoking the corresponding UTF-8 interface.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()].  The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
+** and sqlite3_prepare_v3()
+** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() use UTF-16.
+**
+** ^If the nByte argument is negative, then zSql is read up to the
+** first zero terminator. ^If nByte is positive, then it is the
+** number of bytes read from zSql.  ^If nByte is zero, then no prepared
+** statement is generated.
+** If the caller knows that the supplied string is nul-terminated, then
+** there is a small performance advantage to passing an nByte parameter that
+** is the number of bytes in the input string <i>including</i>
+** the nul-terminator.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql.  These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
+** to NULL.  ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
+** otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
+** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
+** are retained for backwards compatibility, but their use is discouraged.
+** ^In the "vX" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>
+**
+** <li>
+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes].  ^The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and the application would have to make a second call to [sqlite3_reset()]
+** in order to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.
+** </li>
+**
+** <li>
+** ^If the specific value bound to a [parameter | host parameter] in the
+** WHERE clause might influence the choice of query plan for a statement,
+** then the statement will be automatically recompiled, as if there had been
+** a schema change, on the first [sqlite3_step()] call following any change
+** to the [sqlite3_bind_text | bindings] of that [parameter].
+** ^The specific value of a WHERE-clause [parameter] might influence the
+** choice of query plan if the parameter is the left-hand side of a [LIKE]
+** or [GLOB] operator or if the parameter is compared to an indexed column
+** and the [SQLITE_ENABLE_STAT4] compile-time option is enabled.
+** </li>
+** </ol>
+**
+** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
+** the extra prepFlags parameter, which is a bit array consisting of zero or
+** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags.  ^The
+** sqlite3_prepare_v2() interface works exactly the same as
+** sqlite3_prepare_v3() with a zero prepFlags parameter.

+**
+** ^The third argument is the value to bind to the parameter.
+** ^If the third parameter to sqlite3_bind_text() or sqlite3_bind_text16()

+** ^The fifth argument to the BLOB and string binding interfaces controls
+** or indicates the lifetime of the object referenced by the third parameter.
+** These three options exist:
+** ^ (1) A destructor to dispose of the BLOB or string after SQLite has finished
+** with it may be passed. ^It is called to dispose of the BLOB or string even
+** if the call to the bind API fails, except the destructor is not called if
+** the third parameter is a NULL pointer or the fourth parameter is negative.
+** ^ (2) The special constant, [SQLITE_STATIC], may be passsed to indicate that
+** the application remains responsible for disposing of the object. ^In this
+** case, the object and the provided pointer to it must remain valid until
+** either the prepared statement is finalized or the same SQL parameter is
+** bound to something else, whichever occurs sooner.
+** ^ (3) The constant, [SQLITE_TRANSIENT], may be passed to indicate that the
+** object is to be copied prior to the return from sqlite3_bind_*(). ^The
+** object and pointer to it must remain valid until then. ^SQLite will then
+** manage the lifetime of its private copy.
+**
+** ^The sixth argument to sqlite3_bind_text64() must be one of
+** [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE]
+** to specify the encoding of the text in the third parameter.  If
+** the sixth argument to sqlite3_bind_text64() is not one of the
+** allowed values shown above, or if the text encoding is different
+** from the encoding specified by the sixth parameter, then the behavior
+** is undefined.
+**
+** ^The sqlite3_bind_zeroblob() routine binds a BLOB of length N that

+** (just an integer to hold its size) while it is being processed.
+** Zeroblobs are intended to serve as placeholders for BLOBs whose
+** content is later written using
+** [sqlite3_blob_open | incremental BLOB I/O] routines.
+** ^A negative value for the zeroblob results in a zero-length BLOB.
+**
+** ^The sqlite3_bind_pointer(S,I,P,T,D) routine causes the I-th parameter in
+** [prepared statement] S to have an SQL value of NULL, but to also be
+** associated with the pointer P of type T.  ^D is either a NULL pointer or
+** a pointer to a destructor function for P. ^SQLite will invoke the

+** P.  The T parameter should be a static string, preferably a string
+** literal. The sqlite3_bind_pointer() routine is part of the
+** [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^If any of the sqlite3_bind_*() routines are called with a NULL pointer
+** for the [prepared statement] or with a prepared statement for which

+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred.  sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** ^With the legacy interface, a more specific error code (for example,
+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement].  ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
+** be the case that the same database connection is being used by two or
+** more threads at the same moment in time.
+**
+** For all versions of SQLite up to and including 3.6.23.1, a call to
+** [sqlite3_reset()] was required after sqlite3_step() returned anything
+** other than [SQLITE_ROW] before any subsequent invocation of
+** sqlite3_step().  Failure to reset the prepared statement using
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
+** sqlite3_step().  But after [version 3.6.23.1] ([dateof:3.6.23.1],
+** sqlite3_step() began
+** calling [sqlite3_reset()] automatically in this circumstance rather
+** than returning [SQLITE_MISUSE].  This is not considered a compatibility
+** break because any application that ever receives an SQLITE_MISUSE error
+** is broken by definition.  The [SQLITE_OMIT_AUTORESET] compile-time option
+** can be used to restore the legacy behavior.
+**
+** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
+** API always returns a generic error code, [SQLITE_ERROR], following any
+** error other than [SQLITE_BUSY] and [SQLITE_MISUSE].  You must call
+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.
+** We admit that this is a goofy design.  The problem has been fixed
+** with the "v2" interface.  If you prepare all of your SQL statements
+** using [sqlite3_prepare_v3()] or [sqlite3_prepare_v2()]
+** or [sqlite3_prepare16_v2()] or [sqlite3_prepare16_v3()] instead
+** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,
+** then the more specific [error codes] are returned directly
+** by sqlite3_step().  The use of the "vX" interfaces is recommended.

+**
+** <b>Details:</b>
+**
+** ^These routines return information about a single column of the current
+** result row of a query.  ^In every case the first argument is a pointer
+** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
+** that was returned from [sqlite3_prepare_v2()] or one of its variants)
+** and the second argument is the index of the column for which information
+** should be returned. ^The leftmost column of the result set has the index 0.
+** ^The number of columns in the result can be determined using
+** [sqlite3_column_count()].
+**
+** If the SQL statement does not currently point to a valid row, or if the
+** column index is out of range, the result is undefined.
+** These routines may only be called when the most recent call to
+** [sqlite3_step()] has returned [SQLITE_ROW] and neither
+** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
+** If any of these routines are called after [sqlite3_reset()] or
+** [sqlite3_finalize()] or after [sqlite3_step()] has returned
+** something other than [SQLITE_ROW], the results are undefined.
+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
+** are called from a different thread while any of these routines
+** are pending, then the results are undefined.
+**
+** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
+** each return the value of a result column in a specific data format.  If
+** the result column is not initially in the requested format (for example,
+** if the query returns an integer but the sqlite3_column_text() interface
+** is used to extract the value) then an automatic type conversion is performed.
+**
+** ^The sqlite3_column_type() routine returns the
+** [SQLITE_INTEGER | datatype code] for the initial data type
+** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
+** The return value of sqlite3_column_type() can be used to decide which
+** of the first six interface should be used to extract the column value.
+** The value returned by sqlite3_column_type() is only meaningful if no
+** automatic type conversions have occurred for the value in question.
+** After a type conversion, the result of calling sqlite3_column_type()
+** is undefined, though harmless.  Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
+** or sqlite3_column_bytes16() interfaces can be used to determine the size
+** of that BLOB or string.
+**
+** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
+** the string to UTF-8 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
+**
+** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
+** the string to UTF-16 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes16() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
+**
+** ^The values returned by [sqlite3_column_bytes()] and
+** [sqlite3_column_bytes16()] do not include the zero terminators at the end
+** of the string.  ^For clarity: the values returned by
+** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
+** bytes in the string, not the number of characters.
+**
+** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even empty strings, are always zero-terminated.  ^The return
+** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
+**
+** ^Strings returned by sqlite3_column_text16() always have the endianness
+** which is native to the platform, regardless of the text encoding set
+** for the database.
+**
+** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object.  In a multithreaded environment,
+** an unprotected sqlite3_value object may only be used safely with
+** [sqlite3_bind_value()] and [sqlite3_result_value()].
+** If the [unprotected sqlite3_value] object returned by
+** [sqlite3_column_value()] is used in any other way, including calls
+** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
+** or [sqlite3_value_bytes()], the behavior is not threadsafe.
+** Hence, the sqlite3_column_value() interface
+** is normally only useful within the implementation of
+** [application-defined SQL functions] or [virtual tables], not within
+** top-level application code.
+**
+** These routines may attempt to convert the datatype of the result.
+** ^For example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to perform the
+** conversion automatically.  ^(The following table details the conversions
+** that are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
+**
+** <tr><td>  NULL    <td> INTEGER   <td> Result is 0

+** <tr><td>  NULL    <td>   BLOB    <td> Result is a NULL pointer

+** <tr><td> INTEGER  <td>   TEXT    <td> ASCII rendering of the integer
+** <tr><td> INTEGER  <td>   BLOB    <td> Same as INTEGER->TEXT

+** </blockquote>)^
+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+**      sqlite3_column_text16() is called.  A zero-terminator might
+**      need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+**      sqlite3_column_text16() is called.  The content must be converted
+**      to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+**      sqlite3_column_text() is called.  The content must be converted
+**      to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified.  Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** ^The pointers returned are valid until a type conversion occurs as
+** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
+** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
+** and BLOBs is freed automatically.  Do not pass the pointers returned
+** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** As long as the input parameters are correct, these routines will only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_column_blob()
+** <li> sqlite3_column_text()
+** <li> sqlite3_column_text16()
+** <li> sqlite3_column_bytes()
+** <li> sqlite3_column_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** CAPI3REF: Create Or Redefine SQL Functions

+**
+** ^These functions (collectively known as "function creation routines")
+** are used to add SQL functions or aggregates or to redefine the behavior
+** of existing SQL functions or aggregates. The only differences between
+** the three "sqlite3_create_function*" routines are the text encoding
+** expected for the second parameter (the name of the function being
+** created) and the presence or absence of a destructor callback for
+** the application data pointer. Function sqlite3_create_window_function()
+** is similar, but allows the user to supply the extra callback functions
+** needed by [aggregate window functions].
+**
+** ^The first parameter is the [database connection] to which the SQL
+** function is to be added.  ^If an application uses more than one database
+** connection then application-defined SQL functions must be added
+** to each database connection separately.
+**
+** ^The second parameter is the name of the SQL function to be created or
+** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
+** representation, exclusive of the zero-terminator.  ^Note that the name
+** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.
+** ^Any attempt to create a function with a longer name
+** will result in [SQLITE_MISUSE] being returned.
+**
+** ^The third parameter (nArg)
+** is the number of arguments that the SQL function or
+** aggregate takes. ^If this parameter is -1, then the SQL function or
+** aggregate may take any number of arguments between 0 and the limit
+** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
+** parameter is less than -1 or greater than 127 then the behavior is
+** undefined.
+**
+** ^The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters.  The application should set this parameter to
+** [SQLITE_UTF16LE] if the function implementation invokes
+** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
+** implementation invokes [sqlite3_value_text16be()] on an input, or
+** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
+** otherwise.  ^The same SQL function may be registered multiple times using
+** different preferred text encodings, with different implementations for
+** each encoding.
+** ^When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+**
+** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
+** to signal that the function will always return the same result given
+** the same inputs within a single SQL statement.  Most SQL functions are
+** deterministic.  The built-in [random()] SQL function is an example of a
+** function that is not deterministic.  The SQLite query planner is able to
+** perform additional optimizations on deterministic functions, so use
+** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
+**
+** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
+** flag, which if present prevents the function from being invoked from
+** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
+** index expressions, or the WHERE clause of partial indexes.
+**
+** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
+** all application-defined SQL functions that do not need to be
+** used inside of triggers, view, CHECK constraints, or other elements of
+** the database schema.  This flags is especially recommended for SQL
+** functions that have side effects or reveal internal application state.
+** Without this flag, an attacker might be able to modify the schema of
+** a database file to include invocations of the function with parameters
+** chosen by the attacker, which the application will then execute when
+** the database file is opened and read.
+**
+** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
+** function can gain access to this pointer using [sqlite3_user_data()].)^
+**
+** ^The sixth, seventh and eighth parameters passed to the three
+** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
+** pointers to C-language functions that implement the SQL function or
+** aggregate. ^A scalar SQL function requires an implementation of the xFunc
+** callback only; NULL pointers must be passed as the xStep and xFinal
+** parameters. ^An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
+** SQL function or aggregate, pass NULL pointers for all three function
+** callbacks.
+**
+** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue
+** and xInverse) passed to sqlite3_create_window_function are pointers to
+** C-language callbacks that implement the new function. xStep and xFinal
+** must both be non-NULL. xValue and xInverse may either both be NULL, in
+** which case a regular aggregate function is created, or must both be
+** non-NULL, in which case the new function may be used as either an aggregate
+** or aggregate window function. More details regarding the implementation
+** of aggregate window functions are
+** [user-defined window functions|available here].
+**
+** ^(If the final parameter to sqlite3_create_function_v2() or
+** sqlite3_create_window_function() is not NULL, then it is destructor for
+** the application data pointer. The destructor is invoked when the function
+** is deleted, either by being overloaded or when the database connection
+** closes.)^ ^The destructor is also invoked if the call to
+** sqlite3_create_function_v2() fails.  ^When the destructor callback is
+** invoked, it is passed a single argument which is a copy of the application
+** data pointer which was the fifth parameter to sqlite3_create_function_v2().
+**
+** ^It is permitted to register multiple implementations of the same
+** functions with the same name but with either differing numbers of
+** arguments or differing preferred text encodings.  ^SQLite will use
+** the implementation that most closely matches the way in which the
+** SQL function is used.  ^A function implementation with a non-negative
+** nArg parameter is a better match than a function implementation with

+** matches the database encoding is a better
+** match than a function where the encoding is different.
+** ^A function where the encoding difference is between UTF16le and UTF16be
+** is a closer match than a function where the encoding difference is
+** between UTF8 and UTF16.
+**
+** ^Built-in functions may be overloaded by new application-defined functions.

+**
+** <b>Details:</b>
+**
+** These routines extract type, size, and content information from
+** [protected sqlite3_value] objects.  Protected sqlite3_value objects
+** are used to pass parameter information into the functions that
+** implement [application-defined SQL functions] and [virtual tables].
+**
+** These routines work only with [protected sqlite3_value] objects.
+** Any attempt to use these routines on an [unprotected sqlite3_value]
+** is not threadsafe.
+**
+** ^These routines work just like the corresponding [column access functions]
+** except that these routines take a single [protected sqlite3_value] object
+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
+**
+** ^The sqlite3_value_text16() interface extracts a UTF-16 string
+** in the native byte-order of the host machine.  ^The
+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+** extract UTF-16 strings as big-endian and little-endian respectively.
+**
+** ^If [sqlite3_value] object V was initialized
+** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
+** and if X and Y are strings that compare equal according to strcmp(X,Y),
+** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
+** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer()
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^(The sqlite3_value_type(V) interface returns the
+** [SQLITE_INTEGER | datatype code] for the initial datatype of the
+** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
+** Other interfaces might change the datatype for an sqlite3_value object.
+** For example, if the datatype is initially SQLITE_INTEGER and
+** sqlite3_value_text(V) is called to extract a text value for that
+** integer, then subsequent calls to sqlite3_value_type(V) might return
+** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
+** occurs is undefined and may change from one release of SQLite to the next.
+**
+** ^(The sqlite3_value_numeric_type() interface attempts to apply
+** numeric affinity to the value.  This means that an attempt is
+** made to convert the value to an integer or floating point.  If
+** such a conversion is possible without loss of information (in other
+** words, if the value is a string that looks like a number)
+** then the conversion is performed.  Otherwise no conversion occurs.
+** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
+**
+** ^Within the [xUpdate] method of a [virtual table], the
+** sqlite3_value_nochange(X) interface returns true if and only if
+** the column corresponding to X is unchanged by the UPDATE operation
+** that the xUpdate method call was invoked to implement and if
+** and the prior [xColumn] method call that was invoked to extracted
+** the value for that column returned without setting a result (probably
+** because it queried [sqlite3_vtab_nochange()] and found that the column
+** was unchanging).  ^Within an [xUpdate] method, any value for which
+** sqlite3_value_nochange(X) is true will in all other respects appear
+** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
+** than within an [xUpdate] method call for an UPDATE statement, then
+** the return value is arbitrary and meaningless.
+**
+** ^The sqlite3_value_frombind(X) interface returns non-zero if the
+** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
+** interfaces.  ^If X comes from an SQL literal value, or a table column,
+** or an expression, then sqlite3_value_frombind(X) returns zero.
+**
+** Please pay particular attention to the fact that the pointer returned
+** from [sqlite3_value_blob()], [sqlite3_value_text()], or
+** [sqlite3_value_text16()] can be invalidated by a subsequent call to
+** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
+** or [sqlite3_value_text16()].
+**
+** These routines must be called from the same thread as
+** the SQL function that supplied the [sqlite3_value*] parameters.
+**
+** As long as the input parameter is correct, these routines can only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_value_blob()
+** <li> sqlite3_value_text()
+** <li> sqlite3_value_text16()
+** <li> sqlite3_value_text16le()
+** <li> sqlite3_value_text16be()
+** <li> sqlite3_value_bytes()
+** <li> sqlite3_value_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
+** set the return value of the application-defined function to be
+** a text string which is represented as UTF-8, UTF-16 native byte order,
+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** ^The sqlite3_result_text64() interface sets the return value of an
+** application-defined function to be a text string in an encoding
+** specified by the fifth (and last) parameter, which must be one
+** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
+** ^SQLite takes the text result from the application from
+** the 2nd parameter of the sqlite3_result_text* interfaces.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is negative, then SQLite takes result text from the 2nd parameter
+** through the first zero character.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined
+** function result.  If the 3rd parameter is non-negative, then it
+** must be the byte offset into the string where the NUL terminator would
+** appear if the string where NUL terminated.  If any NUL characters occur
+** in the string at a byte offset that is less than the value of the 3rd
+** parameter, then the resulting string will contain embedded NULs and the
+** result of expressions operating on strings with embedded NULs is undefined.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
+** function as the destructor on the text or BLOB result when it has
+** finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
+** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
+** assumes that the text or BLOB result is in constant space and does not
+** copy the content of the parameter nor call a destructor on the content
+** when it has finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
+** then SQLite makes a copy of the result into space obtained
+** from [sqlite3_malloc()] before it returns.
+**
+** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
+** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
+** when the encoding is not UTF8, if the input UTF16 begins with a
+** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
+** string and the rest of the string is interpreted according to the
+** byte-order specified by the BOM.  ^The byte-order specified by
+** the BOM at the beginning of the text overrides the byte-order
+** specified by the interface procedure.  ^So, for example, if
+** sqlite3_result_text16le() is invoked with text that begins
+** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
+** first two bytes of input are skipped and the remaining input
+** is interpreted as UTF16BE text.
+**
+** ^For UTF16 input text to the sqlite3_result_text16(),
+** sqlite3_result_text16be(), sqlite3_result_text16le(), and
+** sqlite3_result_text64() routines, if the text contains invalid
+** UTF16 characters, the invalid characters might be converted
+** into the unicode replacement character, U+FFFD.
+**
+** ^The sqlite3_result_value() interface sets the result of
+** the application-defined function to be a copy of the
+** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
+** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
+** so that the [sqlite3_value] specified in the parameter may change or
+** be deallocated after sqlite3_result_value() returns without harm.
+** ^A [protected sqlite3_value] object may always be used where an
+** [unprotected sqlite3_value] object is required, so either
+** kind of [sqlite3_value] object can be used with this interface.
+**
+** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
+** SQL NULL value, just like [sqlite3_result_null(C)], except that it
+** also associates the host-language pointer P or type T with that
+** NULL value such that the pointer can be retrieved within an
+** [application-defined SQL function] using [sqlite3_value_pointer()].
+** ^If the D parameter is not NULL, then it is a pointer to a destructor
+** for the P parameter.  ^SQLite invokes D with P as its only argument
+** when SQLite is finished with P.  The T parameter should be a static
+** string and preferably a string literal. The sqlite3_result_pointer()
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.

+** ^The eTextRep argument determines the encoding of strings passed

+** ^The [SQLITE_UTF16] and [SQLITE_UTF16_ALIGNED] values for eTextRep
+** force strings to be UTF16 with native byte order.
+** ^The [SQLITE_UTF16_ALIGNED] value for eTextRep forces strings to begin
+** on an even byte address.
+**
+** ^The fourth argument, pArg, is an application data pointer that is passed

+**
+** ^The fifth argument, xCompare, is a pointer to the collating function.
+** ^Multiple collating functions can be registered using the same name but
+** with different eTextRep parameters and SQLite will use whichever
+** function requires the least amount of data transformation.
+** ^If the xCompare argument is NULL then the collating function is
+** deleted.  ^When all collating functions having the same name are deleted,
+** that collation is no longer usable.
+**
+** ^The collating function callback is invoked with a copy of the pArg
+** application data pointer and with two strings in the encoding specified

+** if the first string is less than, equal to, or greater than the second,

+** given the same inputs.  If two or more collating functions are registered
+** to the same collation name (using different eTextRep values) then all
+** must give an equivalent answer when invoked with equivalent strings.
+** The collating function must obey the following properties for all

+** CAPI3REF: Virtual Table Indexing Information
+** KEYWORDS: sqlite3_index_info
+**
+** The sqlite3_index_info structure and its substructures is used as part
+** of the [virtual table] interface to
+** pass information into and receive the reply from the [xBestIndex]
+** method of a [virtual table module].  The fields under **Inputs** are the
+** inputs to xBestIndex and are read-only.  xBestIndex inserts its
+** results into the **Outputs** fields.
+**
+** ^(The aConstraint[] array records WHERE clause constraints of the form:
+**
+** <blockquote>column OP expr</blockquote>
+**
+** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
+** stored in aConstraint[].op using one of the
+** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
+** ^(The index of the column is stored in
+** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
+** expr on the right-hand side can be evaluated (and thus the constraint
+** is usable) and false if it cannot.)^
+**
+** ^The optimizer automatically inverts terms of the form "expr OP column"
+** and makes other simplifications to the WHERE clause in an attempt to
+** get as many WHERE clause terms into the form shown above as possible.
+** ^The aConstraint[] array only reports WHERE clause terms that are
+** relevant to the particular virtual table being queried.
+**
+** ^Information about the ORDER BY clause is stored in aOrderBy[].
+** ^Each term of aOrderBy records a column of the ORDER BY clause.
+**
+** The colUsed field indicates which columns of the virtual table may be
+** required by the current scan. Virtual table columns are numbered from
+** zero in the order in which they appear within the CREATE TABLE statement
+** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
+** the corresponding bit is set within the colUsed mask if the column may be
+** required by SQLite. If the table has at least 64 columns and any column
+** to the right of the first 63 is required, then bit 63 of colUsed is also
+** set. In other words, column iCol may be required if the expression
+** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
+** non-zero.
+**
+** The [xBestIndex] method must fill aConstraintUsage[] with information
+** about what parameters to pass to xFilter.  ^If argvIndex>0 then
+** the right-hand side of the corresponding aConstraint[] is evaluated
+** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
+** is true, then the constraint is assumed to be fully handled by the
+** virtual table and might not be checked again by the byte code.)^ ^(The
+** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
+** is left in its default setting of false, the constraint will always be
+** checked separately in byte code.  If the omit flag is change to true, then
+** the constraint may or may not be checked in byte code.  In other words,
+** when the omit flag is true there is no guarantee that the constraint will
+** not be checked again using byte code.)^
+**
+** ^The idxNum and idxPtr values are recorded and passed into the
+** [xFilter] method.
+** ^[sqlite3_free()] is used to free idxPtr if and only if
+** needToFreeIdxPtr is true.
+**
+** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
+** the correct order to satisfy the ORDER BY clause so that no separate
+** sorting step is required.
+**
+** ^The estimatedCost value is an estimate of the cost of a particular
+** strategy. A cost of N indicates that the cost of the strategy is similar
+** to a linear scan of an SQLite table with N rows. A cost of log(N)
+** indicates that the expense of the operation is similar to that of a
+** binary search on a unique indexed field of an SQLite table with N rows.
+**
+** ^The estimatedRows value is an estimate of the number of rows that
+** will be returned by the strategy.
+**
+** The xBestIndex method may optionally populate the idxFlags field with a
+** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+** assumes that the strategy may visit at most one row.
+**
+** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+** SQLite also assumes that if a call to the xUpdate() method is made as
+** part of the same statement to delete or update a virtual table row and the
+** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+** any database changes. In other words, if the xUpdate() returns
+** SQLITE_CONSTRAINT, the database contents must be exactly as they were
+** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+** the xUpdate method are automatically rolled back by SQLite.
+**
+** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
+** structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
+** If a virtual table extension is
+** used with an SQLite version earlier than 3.8.2, the results of attempting
+** to read or write the estimatedRows field are undefined (but are likely
+** to include crashing the application). The estimatedRows field should
+** therefore only be used if [sqlite3_libversion_number()] returns a
+** value greater than or equal to 3008002. Similarly, the idxFlags field
+** was added for [version 3.9.0] ([dateof:3.9.0]).
+** It may therefore only be used if
+** sqlite3_libversion_number() returns a value greater than or equal to
+** 3009000.

+** and Windows.
+**
+** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor

+** before calling sqlite3_initialize() or any other public sqlite3_
+** function that calls sqlite3_initialize().
+**
+** ^The sqlite3_mutex_alloc() routine allocates a new

+** routine returns NULL if it is unable to allocate the requested
+** mutex.  The argument to sqlite3_mutex_alloc() must one of these

+** The mutex implementation does not need to make a distinction

+** implementation is available on the host platform, the mutex subsystem
+** might return such a mutex in response to SQLITE_MUTEX_FAST.

+** use by SQLite only.  Applications that use SQLite mutexes should
+** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
+** SQLITE_MUTEX_RECURSIVE.
+**
+** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
+** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()

+**
+** ^The sqlite3_mutex_free() routine deallocates a previously

+** ^The xMutexInit method defined by this structure is invoked as
+** part of system initialization by the sqlite3_initialize() function.
+** ^The xMutexInit routine is called by SQLite exactly once for each
+** effective call to [sqlite3_initialize()].
+**
+** ^The xMutexEnd method defined by this structure is invoked as
+** part of system shutdown by the sqlite3_shutdown() function. The
+** implementation of this method is expected to release all outstanding
+** resources obtained by the mutex methods implementation, especially
+** those obtained by the xMutexInit method.  ^The xMutexEnd()
+** interface is invoked exactly once for each call to [sqlite3_shutdown()].
+**
+** ^(The remaining seven methods defined by this structure (xMutexAlloc,
+** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
+** xMutexNotheld) implement the following interfaces (respectively):

+** CAPI3REF: SQL Keyword Checking
+**
+** These routines provide access to the set of SQL language keywords
+** recognized by SQLite.  Applications can uses these routines to determine
+** whether or not a specific identifier needs to be escaped (for example,
+** by enclosing in double-quotes) so as not to confuse the parser.
+**
+** The sqlite3_keyword_count() interface returns the number of distinct
+** keywords understood by SQLite.
+**
+** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
+** makes *Z point to that keyword expressed as UTF8 and writes the number
+** of bytes in the keyword into *L.  The string that *Z points to is not
+** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
+** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
+** or L are NULL or invalid pointers then calls to
+** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
+**
+** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
+** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
+** if it is and zero if not.
+**
+** The parser used by SQLite is forgiving.  It is often possible to use
+** a keyword as an identifier as long as such use does not result in a
+** parsing ambiguity.  For example, the statement
+** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
+** creates a new table named "BEGIN" with three columns named
+** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
+** using keywords as identifiers.  Common techniques used to avoid keyword
+** name collisions include:
+** <ul>
+** <li> Put all identifier names inside double-quotes.  This is the official
+**      SQL way to escape identifier names.
+** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
+**      but it is what SQL Server does and so lots of programmers use this
+**      technique.
+** <li> Begin every identifier with the letter "Z" as no SQL keywords start
+**      with "Z".
+** <li> Include a digit somewhere in every identifier name.
+** </ul>
+**
+** Note that the number of keywords understood by SQLite can depend on
+** compile-time options.  For example, "VACUUM" is not a keyword if
+** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option.  Also,
+** new keywords may be added to future releases of SQLite.

+**
+** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
+** register an alternative page cache implementation by passing in an
+** instance of the sqlite3_pcache_methods2 structure.)^
+** In many applications, most of the heap memory allocated by
+** SQLite is used for the page cache.
+** By implementing a
+** custom page cache using this API, an application can better control
+** the amount of memory consumed by SQLite, the way in which
+** that memory is allocated and released, and the policies used to
+** determine exactly which parts of a database file are cached and for
+** how long.
+**
+** The alternative page cache mechanism is an
+** extreme measure that is only needed by the most demanding applications.
+** The built-in page cache is recommended for most uses.
+**
+** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config].  Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.)^
+**
+** [[the xInit() page cache method]]
+** ^(The xInit() method is called once for each effective
+** call to [sqlite3_initialize()])^
+** (usually only once during the lifetime of the process). ^(The xInit()
+** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
+** The intent of the xInit() method is to set up global data structures
+** required by the custom page cache implementation.
+** ^(If the xInit() method is NULL, then the
+** built-in default page cache is used instead of the application defined
+** page cache.)^
+**
+** [[the xShutdown() page cache method]]
+** ^The xShutdown() method is called by [sqlite3_shutdown()].
+** It can be used to clean up
+** any outstanding resources before process shutdown, if required.
+** ^The xShutdown() method may be NULL.
+**
+** ^SQLite automatically serializes calls to the xInit method,
+** so the xInit method need not be threadsafe.  ^The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  All other methods must be threadsafe
+** in multithreaded applications.
+**
+** ^SQLite will never invoke xInit() more than once without an intervening
+** call to xShutdown().
+**
+** [[the xCreate() page cache methods]]
+** ^SQLite invokes the xCreate() method to construct a new cache instance.
+** SQLite will typically create one cache instance for each open database file,
+** though this is not guaranteed. ^The
+** first parameter, szPage, is the size in bytes of the pages that must
+** be allocated by the cache.  ^szPage will always a power of two.  ^The
+** second parameter szExtra is a number of bytes of extra storage
+** associated with each page cache entry.  ^The szExtra parameter will
+** a number less than 250.  SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk.  The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+**
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a
+** single database page.  The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1.  After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact.  If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+**                 Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
+**                 NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^  In between the xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument.  If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single
+** call to xUnpin() unpins the page regardless of the number of prior calls
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible.  The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** See Also: [Using the SQLite Unlock Notification Feature].
+**
+** ^Shared-cache locks are released when a database connection concludes
+** its current transaction, either by committing it or rolling it back.
+**
+** ^When a connection (known as the blocked connection) fails to obtain a
+** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
+** identity of the database connection (the blocking connection) that
+** has locked the required resource is stored internally. ^After an
+** application receives an SQLITE_LOCKED error, it may call the
+** sqlite3_unlock_notify() method with the blocked connection handle as
+** the first argument to register for a callback that will be invoked
+** when the blocking connections current transaction is concluded. ^The
+** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
+** call that concludes the blocking connection's transaction.
+**
+** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
+** there is a chance that the blocking connection will have already
+** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
+** If this happens, then the specified callback is invoked immediately,
+** from within the call to sqlite3_unlock_notify().)^
+**
+** ^If the blocked connection is attempting to obtain a write-lock on a
+** shared-cache table, and more than one other connection currently holds
+** a read-lock on the same table, then SQLite arbitrarily selects one of
+** the other connections to use as the blocking connection.
+**
+** ^(There may be at most one unlock-notify callback registered by a
+** blocked connection. If sqlite3_unlock_notify() is called when the
+** blocked connection already has a registered unlock-notify callback,
+** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
+** called with a NULL pointer as its second argument, then any existing
+** unlock-notify callback is canceled. ^The blocked connections
+** unlock-notify callback may also be canceled by closing the blocked
+** connection using [sqlite3_close()].
+**
+** The unlock-notify callback is not reentrant. If an application invokes
+** any sqlite3_xxx API functions from within an unlock-notify callback, a
+** crash or deadlock may be the result.
+**
+** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
+** returns SQLITE_OK.
+**
+** <b>Callback Invocation Details</b>
+**
+** When an unlock-notify callback is registered, the application provides a
+** single void* pointer that is passed to the callback when it is invoked.
+** However, the signature of the callback function allows SQLite to pass
+** it an array of void* context pointers. The first argument passed to
+** an unlock-notify callback is a pointer to an array of void* pointers,
+** and the second is the number of entries in the array.
+**
+** When a blocking connection's transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just
+** SQLITE_LOCKED.)^

+** ^(A constraint on a virtual table of the form

+** that invokes the [xFilter|xFilter() method] once for each value
+** on the right-hand side of the IN operator.)^  Thus the virtual table
+** only sees a single value from the right-hand side of the IN operator
+** at a time.
+**
+** In some cases, however, it would be advantageous for the virtual
+** table to see all values on the right-hand of the IN operator all at
+** once.  The sqlite3_vtab_in() interfaces facilitates this in two ways:
+**
+** <ol>
+** <li><p>
+**   ^A call to sqlite3_vtab_in(P,N,-1) will return true (non-zero)

+**   is an [IN operator] that can be processed all at once.  ^In other words,
+**   sqlite3_vtab_in() with -1 in the third argument is a mechanism
+**   by which the virtual table can ask SQLite if all-at-once processing
+**   of the IN operator is even possible.
+**
+** <li><p>
+**   ^A call to sqlite3_vtab_in(P,N,F) with F==1 or F==0 indicates
+**   to SQLite that the virtual table does or does not want to process
+**   the IN operator all-at-once, respectively.  ^Thus when the third
+**   parameter (F) is non-negative, this interface is the mechanism by
+**   which the virtual table tells SQLite how it wants to process the
+**   IN operator.
+** </ol>
+**
+** ^The sqlite3_vtab_in(P,N,F) interface can be invoked multiple times
+** within the same xBestIndex method call.  ^For any given P,N pair,
+** the return value from sqlite3_vtab_in(P,N,F) will always be the same
+** within the same xBestIndex call.  ^If the interface returns true
+** (non-zero), that means that the constraint is an IN operator
+** that can be processed all-at-once.  ^If the constraint is not an IN
+** operator or cannot be processed all-at-once, then the interface returns
+** false.
+**
+** ^(All-at-once processing of the IN operator is selected if both of the

+** non-negative had F>=1.

+** <h3>Special sqlite_stat1 Handling</h3>
+**
+** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to
+** some of the rules above. In SQLite, the schema of sqlite_stat1 is:
+**  <pre>
+**  &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)
+**  </pre>
+**
+** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are
+** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes
+** are recorded for rows for which (idx IS NULL) is true. However, for such
+** rows a zero-length blob (SQL value X'') is stored in the changeset or
+** patchset instead of a NULL value. This allows such changesets to be
+** manipulated by legacy implementations of sqlite3changeset_invert(),
+** concat() and similar.
+**
+** The sqlite3changeset_apply() function automatically converts the
+** zero-length blob back to a NULL value when updating the sqlite_stat1
+** table. However, if the application calls sqlite3changeset_new(),
+** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset
+** iterator directly (including on a changeset iterator passed to a
+** conflict-handler callback) then the X'' value is returned. The application
+** must translate X'' to NULL itself if required.
+**
+** Legacy (older than 3.22.0) versions of the sessions module cannot capture
+** changes made to the sqlite_stat1 table. Legacy versions of the
+** sqlite3changeset_apply() function silently ignore any modifications to the
+** sqlite_stat1 table that are part of a changeset or patchset.

+** and *pnChangeset to the size of the changeset in bytes before returning
+** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
+** zero and return an SQLite error code.
+**
+** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
+** each representing a change to a single row of an attached table. An INSERT
+** change contains the values of each field of a new database row. A DELETE
+** contains the original values of each field of a deleted database row. An
+** UPDATE change contains the original values of each field of an updated
+** database row along with the updated values for each updated non-primary-key
+** column. It is not possible for an UPDATE change to represent a change that
+** modifies the values of primary key columns. If such a change is made, it
+** is represented in a changeset as a DELETE followed by an INSERT.
+**
+** Changes are not recorded for rows that have NULL values stored in one or
+** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+** no corresponding change is present in the changesets returned by this
+** function. If an existing row with one or more NULL values stored in
+** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+** only an INSERT is appears in the changeset. Similarly, if an existing row
+** with non-NULL PRIMARY KEY values is updated so that one or more of its
+** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+** DELETE change only.
+**
+** The contents of a changeset may be traversed using an iterator created
+** using the [sqlite3changeset_start()] API. A changeset may be applied to
+** a database with a compatible schema using the [sqlite3changeset_apply()]
+** API.
+**
+** Within a changeset generated by this function, all changes related to a
+** single table are grouped together. In other words, when iterating through
+** a changeset or when applying a changeset to a database, all changes related
+** to a single table are processed before moving on to the next table. Tables
+** are sorted in the same order in which they were attached (or auto-attached)
+** to the sqlite3_session object. The order in which the changes related to
+** a single table are stored is undefined.
+**
+** Following a successful call to this function, it is the responsibility of
+** the caller to eventually free the buffer that *ppChangeset points to using
+** [sqlite3_free()].
+**
+** <h3>Changeset Generation</h3>
+**
+** Once a table has been attached to a session object, the session object
+** records the primary key values of all new rows inserted into the table.
+** It also records the original primary key and other column values of any
+** deleted or updated rows. For each unique primary key value, data is only
+** recorded once - the first time a row with said primary key is inserted,
+** updated or deleted in the lifetime of the session.
+**
+** There is one exception to the previous paragraph: when a row is inserted,
+** updated or deleted, if one or more of its primary key columns contain a
+** NULL value, no record of the change is made.
+**
+** The session object therefore accumulates two types of records - those
+** that consist of primary key values only (created when the user inserts
+** a new record) and those that consist of the primary key values and the
+** original values of other table columns (created when the users deletes
+** or updates a record).
+**
+** When this function is called, the requested changeset is created using
+** both the accumulated records and the current contents of the database
+** file. Specifically:
+**
+** <ul>
+**   <li> For each record generated by an insert, the database is queried
+**        for a row with a matching primary key. If one is found, an INSERT
+**        change is added to the changeset. If no such row is found, no change
+**        is added to the changeset.
+**
+**   <li> For each record generated by an update or delete, the database is
+**        queried for a row with a matching primary key. If such a row is
+**        found and one or more of the non-primary key fields have been
+**        modified from their original values, an UPDATE change is added to
+**        the changeset. Or, if no such row is found in the table, a DELETE
+**        change is added to the changeset. If there is a row with a matching
+**        primary key in the database, but all fields contain their original
+**        values, no change is added to the changeset.
+** </ul>
+**
+** This means, amongst other things, that if a row is inserted and then later
+** deleted while a session object is active, neither the insert nor the delete
+** will be present in the changeset. Or if a row is deleted and then later a
+** row with the same primary key values inserted while a session object is
+** active, the resulting changeset will contain an UPDATE change instead of
+** a DELETE and an INSERT.
+**
+** When a session object is disabled (see the [sqlite3session_enable()] API),
+** it does not accumulate records when rows are inserted, updated or deleted.
+** This may appear to have some counter-intuitive effects if a single row
+** is written to more than once during a session. For example, if a row
+** is inserted while a session object is enabled, then later deleted while
+** the same session object is disabled, no INSERT record will appear in the
+** changeset, even though the delete took place while the session was disabled.
+** Or, if one field of a row is updated while a session is disabled, and
+** another field of the same row is updated while the session is enabled, the
+** resulting changeset will contain an UPDATE change that updates both fields.

+**
+** The fourth argument (xFilter) passed to these functions is the "filter
+** callback". If it is not NULL, then for each table affected by at least one
+** change in the changeset, the filter callback is invoked with
+** the table name as the second argument, and a copy of the context pointer
+** passed as the sixth argument as the first. If the "filter callback"
+** returns zero, then no attempt is made to apply any changes to the table.
+** Otherwise, if the return value is non-zero or the xFilter argument to
+** is NULL, all changes related to the table are attempted.
+**
+** For each table that is not excluded by the filter callback, this function
+** tests that the target database contains a compatible table. A table is
+** considered compatible if all of the following are true:
+**
+** <ul>
+**   <li> The table has the same name as the name recorded in the
+**        changeset, and
+**   <li> The table has at least as many columns as recorded in the
+**        changeset, and
+**   <li> The table has primary key columns in the same position as
+**        recorded in the changeset.
+** </ul>
+**
+** If there is no compatible table, it is not an error, but none of the
+** changes associated with the table are applied. A warning message is issued
+** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
+** one such warning is issued for each table in the changeset.
+**
+** For each change for which there is a compatible table, an attempt is made
+** to modify the table contents according to the UPDATE, INSERT or DELETE
+** change. If a change cannot be applied cleanly, the conflict handler
+** function passed as the fifth argument to sqlite3changeset_apply() may be
+** invoked. A description of exactly when the conflict handler is invoked for
+** each type of change is below.
+**
+** Unlike the xFilter argument, xConflict may not be passed NULL. The results
+** of passing anything other than a valid function pointer as the xConflict
+** argument are undefined.
+**
+** Each time the conflict handler function is invoked, it must return one
+** of [SQLITE_CHANGESET_OMIT], [SQLITE_CHANGESET_ABORT] or
+** [SQLITE_CHANGESET_REPLACE]. SQLITE_CHANGESET_REPLACE may only be returned
+** if the second argument passed to the conflict handler is either
+** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
+** returns an illegal value, any changes already made are rolled back and
+** the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different
+** actions are taken by sqlite3changeset_apply() depending on the value
+** returned by each invocation of the conflict-handler function. Refer to
+** the documentation for the three
+** [SQLITE_CHANGESET_OMIT|available return values] for details.
+**
+** <dl>
+** <dt>DELETE Changes<dd>
+**   For each DELETE change, the function checks if the target database
+**   contains a row with the same primary key value (or values) as the
+**   original row values stored in the changeset. If it does, and the values
+**   stored in all non-primary key columns also match the values stored in
+**   the changeset the row is deleted from the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the non-primary key fields contains a value different from the original
+**   row value stored in the changeset, the conflict-handler function is
+**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
+**   database table has more columns than are recorded in the changeset,
+**   only the values of those non-primary key fields are compared against
+**   the current database contents - any trailing database table columns
+**   are ignored.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
+**   (which can only happen if a foreign key constraint is violated), the
+**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
+**   passed as the second argument. This includes the case where the DELETE
+**   operation is attempted because an earlier call to the conflict handler
+**   function returned [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>INSERT Changes<dd>
+**   For each INSERT change, an attempt is made to insert the new row into
+**   the database. If the changeset row contains fewer fields than the
+**   database table, the trailing fields are populated with their default
+**   values.
+**
+**   If the attempt to insert the row fails because the database already
+**   contains a row with the same primary key values, the conflict handler
+**   function is invoked with the second argument set to
+**   [SQLITE_CHANGESET_CONFLICT].
+**
+**   If the attempt to insert the row fails because of some other constraint
+**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is
+**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
+**   This includes the case where the INSERT operation is re-attempted because
+**   an earlier call to the conflict handler function returned
+**   [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>UPDATE Changes<dd>
+**   For each UPDATE change, the function checks if the target database
+**   contains a row with the same primary key value (or values) as the
+**   original row values stored in the changeset. If it does, and the values
+**   stored in all modified non-primary key columns also match the values

+**
+**   If a row with matching primary key values is found, but one or more of
+**   the modified non-primary key fields contains a value different from an
+**   original row value stored in the changeset, the conflict-handler function
+**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
+**   UPDATE changes only contain values for non-primary key fields that are
+**   to be modified, only those fields need to match the original values to
+**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the UPDATE operation is attempted, but SQLite returns
+**   SQLITE_CONSTRAINT, the conflict-handler function is invoked with
+**   [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
+**   This includes the case where the UPDATE operation is attempted after

+** CAPI3REF: Rebasing changesets
+** EXPERIMENTAL
+**
+** Suppose there is a site hosting a database in state S0. And that
+** modifications are made that move that database to state S1 and a
+** changeset recorded (the "local" changeset). Then, a changeset based
+** on S0 is received from another site (the "remote" changeset) and
+** applied to the database. The database is then in state
+** (S1+"remote"), where the exact state depends on any conflict
+** resolution decisions (OMIT or REPLACE) made while applying "remote".
+** Rebasing a changeset is to update it to take those conflict
+** resolution decisions into account, so that the same conflicts
+** do not have to be resolved elsewhere in the network.
+**
+** For example, if both the local and remote changesets contain an
+** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
+**
+**   local:  INSERT INTO t1 VALUES(1, 'v1');
+**   remote: INSERT INTO t1 VALUES(1, 'v2');
+**
+** and the conflict resolution is REPLACE, then the INSERT change is
+** removed from the local changeset (it was overridden). Or, if the
+** conflict resolution was "OMIT", then the local changeset is modified
+** to instead contain:
+**
+**           UPDATE t1 SET b = 'v2' WHERE a=1;
+**
+** Changes within the local changeset are rebased as follows:
+**
+** <dl>
+** <dt>Local INSERT<dd>
+**   This may only conflict with a remote INSERT. If the conflict
+**   resolution was OMIT, then add an UPDATE change to the rebased
+**   changeset. Or, if the conflict resolution was REPLACE, add
+**   nothing to the rebased changeset.
+**
+** <dt>Local DELETE<dd>
+**   This may conflict with a remote UPDATE or DELETE. In both cases the
+**   only possible resolution is OMIT. If the remote operation was a
+**   DELETE, then add no change to the rebased changeset. If the remote
+**   operation was an UPDATE, then the old.* fields of change are updated
+**   to reflect the new.* values in the UPDATE.
+**
+** <dt>Local UPDATE<dd>
+**   This may conflict with a remote UPDATE or DELETE. If it conflicts
+**   with a DELETE, and the conflict resolution was OMIT, then the update
+**   is changed into an INSERT. Any undefined values in the new.* record
+**   from the update change are filled in using the old.* values from
+**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+**   the UPDATE change is simply omitted from the rebased changeset.
+**
+**   If conflict is with a remote UPDATE and the resolution is OMIT, then
+**   the old.* values are rebased using the new.* values in the remote
+**   change. Or, if the resolution is REPLACE, then the change is copied
+**   into the rebased changeset with updates to columns also updated by
+**   the conflicting remote UPDATE removed. If this means no columns would
+**   be updated, the change is omitted.
+** </dl>
+**
+** A local change may be rebased against multiple remote changes
+** simultaneously. If a single key is modified by multiple remote
+** changesets, they are combined as follows before the local changeset
+** is rebased:
+**
+** <ul>
+**    <li> If there has been one or more REPLACE resolutions on a
+**         key, it is rebased according to a REPLACE.
+**
+**    <li> If there have been no REPLACE resolutions on a key, then
+**         the local changeset is rebased according to the most recent
+**         of the OMIT resolutions.
+** </ul>
+**
+** Note that conflict resolutions from multiple remote changesets are
+** combined on a per-field basis, not per-row. This means that in the
+** case of multiple remote UPDATE operations, some fields of a single
+** local change may be rebased for REPLACE while others are rebased for
+** OMIT.
+**
+** In order to rebase a local changeset, the remote changeset must first
+** be applied to the local database using sqlite3changeset_apply_v2() and
+** the buffer of rebase information captured. Then:
+**
+** <ol>
+**   <li> An sqlite3_rebaser object is created by calling
+**        sqlite3rebaser_create().
+**   <li> The new object is configured with the rebase buffer obtained from
+**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+**        If the local changeset is to be rebased against multiple remote
+**        changesets, then sqlite3rebaser_configure() should be called
+**        multiple times, in the same order that the multiple
+**        sqlite3changeset_apply_v2() calls were made.
+**   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().

+**
+** Non-streaming functions that accept changesets (or patchsets) as input
+** require that the entire changeset be stored in a single buffer in memory.
+** Similarly, those that return a changeset or patchset do so by returning
+** a pointer to a single large buffer allocated using sqlite3_malloc().
+** Normally this is convenient. However, if an application running in a
+** low-memory environment is required to handle very large changesets, the
+** large contiguous memory allocations required can become onerous.
+**
+** In order to avoid this problem, instead of a single large buffer, input
+** is passed to a streaming API functions by way of a callback function that
+** the sessions module invokes to incrementally request input data as it is
+** required. In all cases, a pair of API function parameters such as
+**
+**  <pre>
+**  &nbsp;     int nChangeset,
+**  &nbsp;     void *pChangeset,
+**  </pre>
+**
+** Is replaced by:

+**  <pre>
+**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+**  &nbsp;     void *pIn,
+**  </pre>
+**
+** Each time the xInput callback is invoked by the sessions module, the first
+** argument passed is a copy of the supplied pIn context pointer. The second
+** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no
+** error occurs the xInput method should copy up to (*pnData) bytes of data
+** into the buffer and set (*pnData) to the actual number of bytes copied
+** before returning SQLITE_OK. If the input is completely exhausted, (*pnData)
+** should be set to zero to indicate this. Or, if an error occurs, an SQLite
+** error code should be returned. In all cases, if an xInput callback returns
+** an error, all processing is abandoned and the streaming API function
+** returns a copy of the error code to the caller.
+**
+** In the case of sqlite3changeset_start_strm(), the xInput callback may be
+** invoked by the sessions module at any point during the lifetime of the
+** iterator. If such an xInput callback returns an error, the iterator enters
+** an error state, whereby all subsequent calls to iterator functions
+** immediately fail with the same error code as returned by xInput.
+**
+** Similarly, streaming API functions that return changesets (or patchsets)
+** return them in chunks by way of a callback function instead of via a
+** pointer to a single large buffer. In this case, a pair of parameters such
+** as:
+**
+**  <pre>
+**  &nbsp;     int *pnChangeset,
+**  &nbsp;     void **ppChangeset,
+**  </pre>
+**
+** Is replaced by:
+**
+**  <pre>
+**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+**  &nbsp;     void *pOut
+**  </pre>
+**
+** The xOutput callback is invoked zero or more times to return data to
+** the application. The first parameter passed to each call is a copy of the
+** pOut pointer supplied by the application. The second parameter, pData,
+** points to a buffer nData bytes in size containing the chunk of output
+** data being returned. If the xOutput callback successfully processes the
+** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
+** it should return some other SQLite error code. In this case processing
+** is immediately abandoned and the streaming API function returns a copy
+** of the xOutput error code to the application.
+**
+** The sessions module never invokes an xOutput callback with the third
+** parameter set to a value less than or equal to zero. Other than this,

+** EXTENSION API FUNCTIONS
+**
+** xUserData(pFts):
+**   Return a copy of the context pointer the extension function was
+**   registered with.
+**
+** xColumnTotalSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the FTS5 table. Or, if iCol is
+**   non-negative but less than the number of columns in the table, return
+**   the total number of tokens in column iCol, considering all rows in
+**   the FTS5 table.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+** xColumnCount(pFts):
+**   Return the number of columns in the table.
+**
+** xColumnSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the current row. Or, if iCol is
+**   non-negative but less than the number of columns in the table, set
+**   *pnToken to the number of tokens in column iCol of the current row.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+**   This function may be quite inefficient if used with an FTS5 table
+**   created with the "columnsize=0" option.
+**
+** xColumnText:
+**   This function attempts to retrieve the text of column iCol of the
+**   current document. If successful, (*pz) is set to point to a buffer
+**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+**   if an error occurs, an SQLite error code is returned and the final values
+**   of (*pz) and (*pn) are undefined.
+**
+** xPhraseCount:
+**   Returns the number of phrases in the current query expression.
+**
+** xPhraseSize:
+**   Returns the number of tokens in phrase iPhrase of the query. Phrases
+**   are numbered starting from zero.
+**
+** xInstCount:
+**   Set *pnInst to the total number of occurrences of all phrases within
+**   the query within the current row. Return SQLITE_OK if successful, or
+**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always returns 0.
+**
+** xInst:
+**   Query for the details of phrase match iIdx within the current row.
+**   Phrase matches are numbered starting from zero, so the iIdx argument
+**   should be greater than or equal to zero and smaller than the value
+**   output by xInstCount().
+**
+**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
+**   to the column in which it occurs and *piOff the token offset of the
+**   first token of the phrase. Returns SQLITE_OK if successful, or an error
+**   code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option.
+**
+** xRowid:
+**   Returns the rowid of the current row.
+**
+** xTokenize:
+**   Tokenize text using the tokenizer belonging to the FTS5 table.
+**
+** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+**   This API function is used to query the FTS table for phrase iPhrase
+**   of the current query. Specifically, a query equivalent to:
+**
+**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+**
+**   with $p set to a phrase equivalent to the phrase iPhrase of the
+**   current query is executed. Any column filter that applies to
+**   phrase iPhrase of the current query is included in $p. For each
+**   row visited, the callback function passed as the fourth argument
+**   is invoked. The context and API objects passed to the callback
+**   function may be used to access the properties of each matched row.
+**   Invoking Api.xUserData() returns a copy of the pointer passed as
+**   the third argument to pUserData.
+**
+**   If the callback function returns any value other than SQLITE_OK, the
+**   query is abandoned and the xQueryPhrase function returns immediately.
+**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+**   Otherwise, the error code is propagated upwards.
+**
+**   If the query runs to completion without incident, SQLITE_OK is returned.
+**   Or, if some error occurs before the query completes or is aborted by
+**   the callback, an SQLite error code is returned.
+**
+**
+** xSetAuxdata(pFts5, pAux, xDelete)
+**
+**   Save the pointer passed as the second argument as the extension function's
+**   "auxiliary data". The pointer may then be retrieved by the current or any
+**   future invocation of the same fts5 extension function made as part of
+**   the same MATCH query using the xGetAuxdata() API.
+**
+**   Each extension function is allocated a single auxiliary data slot for
+**   each FTS query (MATCH expression). If the extension function is invoked
+**   more than once for a single FTS query, then all invocations share a
+**   single auxiliary data context.
+**
+**   If there is already an auxiliary data pointer when this function is
+**   invoked, then it is replaced by the new pointer. If an xDelete callback
+**   was specified along with the original pointer, it is invoked at this
+**   point.
+**
+**   The xDelete callback, if one is specified, is also invoked on the
+**   auxiliary data pointer after the FTS5 query has finished.
+**
+**   If an error (e.g. an OOM condition) occurs within this function,
+**   the auxiliary data is set to NULL and an error code returned. If the
+**   xDelete parameter was not NULL, it is invoked on the auxiliary data
+**   pointer before returning.
+**
+**
+** xGetAuxdata(pFts5, bClear)
+**
+**   Returns the current auxiliary data pointer for the fts5 extension
+**   function. See the xSetAuxdata() method for details.
+**
+**   If the bClear argument is non-zero, then the auxiliary data is cleared
+**   (set to NULL) before this function returns. In this case the xDelete,
+**   if any, is not invoked.
+**
+**
+** xRowCount(pFts5, pnRow)
+**
+**   This function is used to retrieve the total number of rows in the table.
+**   In other words, the same value that would be returned by:
+**
+**        SELECT count(*) FROM ftstable;
+**
+** xPhraseFirst()
+**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
+**   method, to iterate through all instances of a single query phrase within
+**   the current row. This is the same information as is accessible via the
+**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+**   to use, this API may be faster under some circumstances. To iterate
+**   through instances of phrase iPhrase, use the following code:
+**
+**       Fts5PhraseIter iter;
+**       int iCol, iOff;
+**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+**           iCol>=0;
+**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+**       ){
+**         // An instance of phrase iPhrase at offset iOff of column iCol
+**       }
+**
+**   The Fts5PhraseIter structure is defined above. Applications should not
+**   modify this structure directly - it should only be used as shown above
+**   with the xPhraseFirst() and xPhraseNext() API methods (and by
+**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always iterates
+**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
+**
+** xPhraseNext()
+**   See xPhraseFirst above.
+**
+** xPhraseFirstColumn()
+**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+**   and xPhraseNext() APIs described above. The difference is that instead
+**   of iterating through all instances of a phrase in the current row, these
+**   APIs are used to iterate through the set of columns in the current row
+**   that contain one or more instances of a specified phrase. For example:
+**
+**       Fts5PhraseIter iter;
+**       int iCol;
+**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+**           iCol>=0;
+**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+**       ){
+**         // Column iCol contains at least one instance of phrase iPhrase
+**       }
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" option. If the FTS5 table is created with either
+**   "detail=none" "content=" option (i.e. if it is a contentless table),
+**   then this API always iterates through an empty set (all calls to
+**   xPhraseFirstColumn() set iCol to -1).
+**
+**   The information accessed using this API and its companion
+**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+**   (or xInst/xInstCount). The chief advantage of this API is that it is
+**   significantly more efficient than those alternatives when used with
+**   "detail=column" tables.
+**
+** xPhraseNextColumn()
+**   See xPhraseFirstColumn above.

+** CUSTOM AUXILIARY FUNCTIONS
+*************************************************************************/
+
+/*************************************************************************
+** CUSTOM TOKENIZERS
+**
+** Applications may also register custom tokenizer types. A tokenizer
+** is registered by providing fts5 with a populated instance of the
+** following structure. All structure methods must be defined, setting
+** any member of the fts5_tokenizer struct to NULL leads to undefined
+** behaviour. The structure methods are expected to function as follows:
+**
+** xCreate:
+**   This function is used to allocate and initialize a tokenizer instance.
+**   A tokenizer instance is required to actually tokenize text.
+**
+**   The first argument passed to this function is a copy of the (void*)
+**   pointer provided by the application when the fts5_tokenizer object
+**   was registered with FTS5 (the third argument to xCreateTokenizer()).
+**   The second and third arguments are an array of nul-terminated strings
+**   containing the tokenizer arguments, if any, specified following the
+**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
+**   to create the FTS5 table.
+**
+**   The final argument is an output variable. If successful, (*ppOut)
+**   should be set to point to the new tokenizer handle and SQLITE_OK
+**   returned. If an error occurs, some value other than SQLITE_OK should
+**   be returned. In this case, fts5 assumes that the final value of *ppOut
+**   is undefined.
+**
+** xDelete:
+**   This function is invoked to delete a tokenizer handle previously
+**   allocated using xCreate(). Fts5 guarantees that this function will
+**   be invoked exactly once for each successful call to xCreate().
+**
+** xTokenize:
+**   This function is expected to tokenize the nText byte string indicated
+**   by argument pText. pText may or may not be nul-terminated. The first
+**   argument passed to this function is a pointer to an Fts5Tokenizer object
+**   returned by an earlier call to xCreate().
+**
+**   The second argument indicates the reason that FTS5 is requesting
+**   tokenization of the supplied text. This is always one of the following
+**   four values:
+**
+**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
+**            or removed from the FTS table. The tokenizer is being invoked to
+**            determine the set of tokens to add to (or delete from) the
+**            FTS index.
+**
+**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed
+**            against the FTS index. The tokenizer is being called to tokenize
+**            a bareword or quoted string specified as part of the query.
+**
+**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
+**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
+**            followed by a "*" character, indicating that the last token
+**            returned by the tokenizer will be treated as a token prefix.
+**
+**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to
+**            satisfy an fts5_api.xTokenize() request made by an auxiliary
+**            function. Or an fts5_api.xColumnSize() request made by the same
+**            on a columnsize=0 database.
+**   </ul>
+**
+**   For each token in the input string, the supplied callback xToken() must
+**   be invoked. The first argument to it should be a copy of the pointer
+**   passed as the second argument to xTokenize(). The third and fourth
+**   arguments are a pointer to a buffer containing the token text, and the
+**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
+**   of the first byte of and first byte immediately following the text from
+**   which the token is derived within the input.
+**
+**   The second argument passed to the xToken() callback ("tflags") should
+**   normally be set to 0. The exception is if the tokenizer supports
+**   synonyms. In this case see the discussion below for details.
+**
+**   FTS5 assumes the xToken() callback is invoked for each token in the
+**   order that they occur within the input text.
+**
+**   If an xToken() callback returns any value other than SQLITE_OK, then
+**   the tokenization should be abandoned and the xTokenize() method should
+**   immediately return a copy of the xToken() return value. Or, if the
+**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
+**   if an error occurs with the xTokenize() implementation itself, it
+**   may abandon the tokenization and return any error code other than
+**   SQLITE_OK or SQLITE_DONE.
+**
+** SYNONYM SUPPORT
+**
+**   Custom tokenizers may also support synonyms. Consider a case in which a
+**   user wishes to query for a phrase such as "first place". Using the
+**   built-in tokenizers, the FTS5 query 'first + place' will match instances
+**   of "first place" within the document set, but not alternative forms
+**   such as "1st place". In some applications, it would be better to match
+**   all instances of "first place" or "1st place" regardless of which form
+**   the user specified in the MATCH query text.
+**
+**   There are several ways to approach this in FTS5:
+**
+**   <ol><li> By mapping all synonyms to a single token. In this case, using
+**            the above example, this means that the tokenizer returns the
+**            same token for inputs "first" and "1st". Say that token is in
+**            fact "first", so that when the user inserts the document "I won
+**            1st place" entries are added to the index for tokens "i", "won",
+**            "first" and "place". If the user then queries for '1st + place',
+**            the tokenizer substitutes "first" for "1st" and the query works
+**            as expected.
+**
+**       <li> By querying the index for all synonyms of each query term
+**            separately. In this case, when tokenizing query text, the
+**            tokenizer may provide multiple synonyms for a single term
+**            within the document. FTS5 then queries the index for each
+**            synonym individually. For example, faced with the query:
+**
+**   <codeblock>
+**     ... MATCH 'first place'</codeblock>
+**
+**            the tokenizer offers both "1st" and "first" as synonyms for the
+**            first token in the MATCH query and FTS5 effectively runs a query
+**            similar to:
+**
+**   <codeblock>
+**     ... MATCH '(first OR 1st) place'</codeblock>
+**
+**            except that, for the purposes of auxiliary functions, the query
+**            still appears to contain just two phrases - "(first OR 1st)"
+**            being treated as a single phrase.
+**
+**       <li> By adding multiple synonyms for a single term to the FTS index.
+**            Using this method, when tokenizing document text, the tokenizer
+**            provides multiple synonyms for each token. So that when a
+**            document such as "I won first place" is tokenized, entries are
+**            added to the FTS index for "i", "won", "first", "1st" and
+**            "place".
+**
+**            This way, even if the tokenizer does not provide synonyms
+**            when tokenizing query text (it should not - to do so would be
+**            inefficient), it doesn't matter if the user queries for
+**            'first + place' or '1st + place', as there are entries in the
+**            FTS index corresponding to both forms of the first token.
+**   </ol>
+**
+**   Whether it is parsing document or query text, any call to xToken that
+**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
+**   is considered to supply a synonym for the previous token. For example,
+**   when parsing the document "I won first place", a tokenizer that supports
+**   synonyms would call xToken() 5 times, as follows:
+**
+**   <codeblock>
+**       xToken(pCtx, 0, "i",                      1,  0,  1);
+**       xToken(pCtx, 0, "won",                    3,  2,  5);
+**       xToken(pCtx, 0, "first",                  5,  6, 11);
+**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
+**       xToken(pCtx, 0, "place",                  5, 12, 17);
+**</codeblock>
+**
+**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
+**   xToken() is called. Multiple synonyms may be specified for a single token
+**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence.
+**   There is no limit to the number of synonyms that may be provided for a
+**   single token.
+**
+**   In many cases, method (1) above is the best approach. It does not add
+**   extra data to the FTS index or require FTS5 to query for multiple terms,
+**   so it is efficient in terms of disk space and query speed. However, it
+**   does not support prefix queries very well. If, as suggested above, the
+**   token "first" is substituted for "1st" by the tokenizer, then the query:
+**
+**   <codeblock>
+**     ... MATCH '1s*'</codeblock>
+**
+**   will not match documents that contain the token "1st" (as the tokenizer
+**   will probably not map "1s" to any prefix of "first").
+**
+**   For full prefix support, method (3) may be preferred. In this case,
+**   because the index contains entries for both "first" and "1st", prefix
+**   queries such as 'fi*' or '1s*' will match correctly. However, because
+**   extra entries are added to the FTS index, this method uses more space
+**   within the database.
+**
+**   Method (2) offers a midpoint between (1) and (3). Using this method,
+**   a query such as '1s*' will match documents that contain the literal
+**   token "1st", but not "first" (assuming the tokenizer is not able to
+**   provide synonyms for prefixes). However, a non-prefix query like '1st'
+**   will match against "1st" and "first". This method does not require
+**   extra disk space, as no extra entries are added to the FTS index.
+**   On the other hand, it may require more CPU cycles to run MATCH queries,
+**   as separate queries of the FTS index are required for each synonym.
+**
+**   When using methods (2) or (3), it is important that the tokenizer only
+**   provide synonyms when tokenizing document text (method (2)) or query
+**   text (method (3)), not both. Doing so will not cause any errors, but is
+**   inefficient.

+**     the cursor being hinted.

+**     reduce network bandwidth.

+**
+** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
+** those functions are not available.  So we use only LockFile() and
+** UnlockFile().
+**
+** LockFile() prevents not just writing but also reading by other processes.
+** A SHARED_LOCK is obtained by locking a single randomly-chosen
+** byte out of a specific range of bytes. The lock byte is obtained at
+** random so two separate readers can probably access the file at the
+** same time, unless they are unlucky and choose the same lock byte.
+** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
+** There can only be one writer.  A RESERVED_LOCK is obtained by locking
+** a single byte of the file that is designated as the reserved lock byte.
+** A PENDING_LOCK is obtained by locking a designated byte different from
+** the RESERVED_LOCK byte.
+**
+** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
+** which means we can use reader/writer locks.  When reader/writer locks
+** are used, the lock is placed on the same range of bytes that is used
+** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
+** will support two or more Win95 readers or two or more WinNT readers.
+** But a single Win95 reader will lock out all WinNT readers and a single
+** WinNT reader will lock out all other Win95 readers.
+**
+** The following #defines specify the range of bytes used for locking.
+** SHARED_SIZE is the number of bytes available in the pool from which
+** a random byte is selected for a shared lock.  The pool of bytes for
+** shared locks begins at SHARED_FIRST.
+**
+** The same locking strategy and
+** byte ranges are used for Unix.  This leaves open the possibility of having
+** clients on win95, winNT, and unix all talking to the same shared file
+** and all locking correctly.  To do so would require that samba (or whatever
+** tool is being used for file sharing) implements locks correctly between
+** windows and unix.  I'm guessing that isn't likely to happen, but by
+** using the same locking range we are at least open to the possibility.
+**
+** Locking in windows is manditory.  For this reason, we cannot store
+** actual data in the bytes used for locking.  The pager never allocates
+** the pages involved in locking therefore.  SHARED_SIZE is selected so
+** that all locks will fit on a single page even at the minimum page size.
+** PENDING_BYTE defines the beginning of the locks.  By default PENDING_BYTE
+** is set high so that we don't have to allocate an unused page except
+** for very large databases.  But one should test the page skipping logic
+** by setting PENDING_BYTE low and running the entire regression suite.
+**
+** Changing the value of PENDING_BYTE results in a subtly incompatible
+** file format.  Depending on how it is changed, you might not notice
+** the incompatibility right away, even running a full regression test.
+** The default location of PENDING_BYTE is the first byte past the
+** 1GB boundary.

+** Lookaside malloc is a set of fixed-size buffers that can be used
+** to satisfy small transient memory allocation requests for objects
+** associated with a particular database connection.  The use of
+** lookaside malloc provides a significant performance enhancement
+** (approx 10%) by avoiding numerous malloc/free requests while parsing
+** SQL statements.
+**
+** The Lookaside structure holds configuration information about the
+** lookaside malloc subsystem.  Each available memory allocation in
+** the lookaside subsystem is stored on a linked list of LookasideSlot
+** objects.
+**
+** Lookaside allocations are only allowed for objects that are associated
+** with a particular database connection.  Hence, schema information cannot
+** be stored in lookaside because in shared cache mode the schema information
+** is shared by multiple database connections.  Therefore, while parsing
+** schema information, the Lookaside.bEnabled flag is cleared so that
+** lookaside allocations are not used to construct the schema objects.
+**
+** New lookaside allocations are only allowed if bDisable==0.  When
+** bDisable is greater than zero, sz is set to zero which effectively
+** disables lookaside without adding a new test for the bDisable flag
+** in a performance-critical path.  sz should be set by to szTrue whenever
+** bDisable changes back to zero.
+**
+** Lookaside buffers are initially held on the pInit list.  As they are
+** used and freed, they are added back to the pFree list.  New allocations
+** come off of pFree first, then pInit as a fallback.  This dual-list
+** allows use to compute a high-water mark - the maximum number of allocations
+** outstanding at any point in the past - by subtracting the number of
+** allocations on the pInit list from the total number of allocations.
+**
+** Enhancement on 2019-12-12:  Two-size-lookaside
+** The default lookaside configuration is 100 slots of 1200 bytes each.
+** The larger slot sizes are important for performance, but they waste
+** a lot of space, as most lookaside allocations are less than 128 bytes.
+** The two-size-lookaside enhancement breaks up the lookaside allocation
+** into two pools:  One of 128-byte slots and the other of the default size
+** (1200-byte) slots.   Allocations are filled from the small-pool first,
+** failing over to the full-size pool if that does not work.  Thus more
+** lookaside slots are available while also using less memory.
+** This enhancement can be omitted by compiling with
+** SQLITE_OMIT_TWOSIZE_LOOKASIDE.

+**     zName is the name of a test-only function implemented by in-line
+**     byte code rather than by the usual callbacks. The iFuncId
+**     parameter determines the function id.  The mFlags parameter is
+**     optional SQLITE_FUNC_ flags for this function.
+**
+**   DFUNCTION(zName, nArg, iArg, bNC, xFunc)
+**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
+**     adds the SQLITE_FUNC_SLOCHNG flag.  Used for date & time functions
+**     and functions like sqlite_version() that can change, but not during
+**     a single query.  The iArg is ignored.  The user-data is always set
+**     to a NULL pointer.  The bNC parameter is not used.
+**
+**   MFUNCTION(zName, nArg, xPtr, xFunc)
+**     For math-library functions.  xPtr is an arbitrary pointer.
+**
+**   PURE_DATE(zName, nArg, iArg, bNC, xFunc)
+**     Used for "pure" date/time functions, this macro is like DFUNCTION
+**     except that it does set the SQLITE_FUNC_CONSTANT flags.  iArg is
+**     ignored and the user-data for these functions is set to an
+**     arbitrary non-NULL pointer.  The bNC parameter is not used.
+**
+**   AGGREGATE(zName, nArg, iArg, bNC, xStep, xFinal)
+**     Used to create an aggregate function definition implemented by
+**     the C functions xStep and xFinal. The first four parameters
+**     are interpreted in the same way as the first 4 parameters to
+**     FUNCTION().
+**
+**   WAGGREGATE(zName, nArg, iArg, xStep, xFinal, xValue, xInverse)
+**     Used to create an aggregate function definition implemented by
+**     the C functions xStep and xFinal. The first four parameters
+**     are interpreted in the same way as the first 4 parameters to
+**     FUNCTION().
+**
+**   LIKEFUNC(zName, nArg, pArg, flags)
+**     Used to create a scalar function definition of a function zName
+**     that accepts nArg arguments and is implemented by a call to C
+**     function likeFunc. Argument pArg is cast to a (void *) and made
+**     available as the function user-data (sqlite3_user_data()). The
+**     FuncDef.flags variable is set to the value passed as the flags
+**     parameter.

+** database connections, even when the rest of the in-memory database

+** within the database. So that they appear as part of the callers
+** transaction, these accesses need to be made via the same database
+** connection as that used to execute SQL operations on the virtual table.
+**
+** All VTable objects that correspond to a single table in a shared
+** database schema are initially stored in a linked-list pointed to by
+** the Table.pVTable member variable of the corresponding Table object.
+** When an sqlite3_prepare() operation is required to access the virtual

+** database connection doing the preparing so as to use the correct
+** sqlite3_vtab* handle in the compiled query.

+** corresponding sqlite3 structure. They are then deleted/xDisconnected
+** next time a statement is prepared using said sqlite3*. This is done
+** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
+** Refer to comments above function sqlite3VtabUnlockList() for an
+** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect

+** changes due to the same operation are not backed out and no rollback

+** is returned.  REPLACE means that preexisting database rows that caused
+** a UNIQUE constraint violation are removed so that the new insert or

+**
+** Expr.x.pList is a list of arguments if the expression is an SQL function,

+**
+** If the expression is a subquery then Expr.iColumn holds an integer

+** then iTable is the address of a subroutine that computes the subquery.

+** The results of a SELECT can be distributed in several ways, as defined
+** by one of the following macros.  The "SRT" prefix means "SELECT Result
+** Type".
+**
+**     SRT_Union       Store results as a key in a temporary index
+**                     identified by pDest->iSDParm.
+**
+**     SRT_Except      Remove results from the temporary index pDest->iSDParm.
+**
+**     SRT_Exists      Store a 1 in memory cell pDest->iSDParm if the result
+**                     set is not empty.
+**
+**     SRT_Discard     Throw the results away.  This is used by SELECT
+**                     statements within triggers whose only purpose is
+**                     the side-effects of functions.
+**
+**     SRT_Output      Generate a row of output (using the OP_ResultRow
+**                     opcode) for each row in the result set.
+**
+**     SRT_Mem         Only valid if the result is a single column.
+**                     Store the first column of the first result row
+**                     in register pDest->iSDParm then abandon the rest
+**                     of the query.  This destination implies "LIMIT 1".
+**
+**     SRT_Set         The result must be a single column.  Store each
+**                     row of result as the key in table pDest->iSDParm.
+**                     Apply the affinity pDest->affSdst before storing
+**                     results.  Used to implement "IN (SELECT ...)".
+**
+**     SRT_EphemTab    Create an temporary table pDest->iSDParm and store
+**                     the result there. The cursor is left open after
+**                     returning.  This is like SRT_Table except that
+**                     this destination uses OP_OpenEphemeral to create
+**                     the table first.
+**
+**     SRT_Coroutine   Generate a co-routine that returns a new row of
+**                     results each time it is invoked.  The entry point
+**                     of the co-routine is stored in register pDest->iSDParm
+**                     and the result row is stored in pDest->nDest registers
+**                     starting with pDest->iSdst.
+**
+**     SRT_Table       Store results in temporary table pDest->iSDParm.
+**     SRT_Fifo        This is like SRT_EphemTab except that the table
+**                     is assumed to already be open.  SRT_Fifo has
+**                     the additional property of being able to ignore
+**                     the ORDER BY clause.
+**
+**     SRT_DistFifo    Store results in a temporary table pDest->iSDParm.
+**                     But also use temporary table pDest->iSDParm+1 as
+**                     a record of all prior results and ignore any duplicate
+**                     rows.  Name means:  "Distinct Fifo".
+**
+**     SRT_Queue       Store results in priority queue pDest->iSDParm (really
+**                     an index).  Append a sequence number so that all entries
+**                     are distinct.
+**
+**     SRT_DistQueue   Store results in priority queue pDest->iSDParm only if
+**                     the same record has never been stored before.  The
+**                     index at pDest->iSDParm+1 hold all prior stores.
+**
+**     SRT_Upfrom      Store results in the temporary table already opened by
+**                     pDest->iSDParm. If (pDest->iSDParm<0), then the temp
+**                     table is an intkey table - in this case the first
+**                     column returned by the SELECT is used as the integer
+**                     key. If (pDest->iSDParm>0), then the table is an index
+**                     table. (pDest->iSDParm) is the number of key columns in
+**                     each index record in this case.

+** This file contains the C functions that implement date and time
+** functions for SQLite.
+**
+** There is only one exported symbol in this file - the function
+** sqlite3RegisterDateTimeFunctions() found at the bottom of the file.
+** All other code has file scope.
+**
+** SQLite processes all times and dates as julian day numbers.  The
+** dates and times are stored as the number of days since noon
+** in Greenwich on November 24, 4714 B.C. according to the Gregorian
+** calendar system.
+**
+** 1970-01-01 00:00:00 is JD 2440587.5
+** 2000-01-01 00:00:00 is JD 2451544.5
+**
+** This implementation requires years to be expressed as a 4-digit number
+** which means that only dates between 0000-01-01 and 9999-12-31 can
+** be represented, even though julian day numbers allow a much wider
+** range of dates.
+**
+** The Gregorian calendar system is used for all dates and times,
+** even those that predate the Gregorian calendar.  Historians usually
+** use the julian calendar for dates prior to 1582-10-15 and for some
+** dates afterwards, depending on locale.  Beware of this difference.
+**
+** The conversion algorithms are implemented based on descriptions
+** in the following text:

+**
+** This version of the memory allocation subsystem omits all
+** use of malloc(). The application gives SQLite a block of memory
+** before calling sqlite3_initialize() from which allocations
+** are made and returned by the xMalloc() and xRealloc()
+** implementations. Once sqlite3_initialize() has been called,
+** the amount of memory available to SQLite is fixed and cannot
+** be changed.
+**
+** This version of the memory allocation subsystem is included
+** in the build only if SQLITE_ENABLE_MEMSYS5 is defined.
+**
+** This memory allocator uses the following algorithm:
+**
+**   1.  All memory allocation sizes are rounded up to a power of 2.
+**
+**   2.  If two adjacent free blocks are the halves of a larger block,
+**       then the two blocks are coalesced into the single larger block.
+**
+**   3.  New memory is allocated from the first available free block.
+**
+** This algorithm is described in: J. M. Robson. "Bounds for Some Functions
+** Concerning Dynamic Storage Allocation". Journal of the Association for
+** Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
+**
+** Let n be the size of the largest allocation divided by the minimum
+** allocation size (after rounding all sizes up to a power of 2.)  Let M
+** be the maximum amount of memory ever outstanding at one time.  Let
+** N be the total amount of memory available for allocation.  Robson
+** proved that this memory allocator will never breakdown due to
+** fragmentation as long as the following constraint holds:
+**
+**      N >=  M*(1 + log2(n)/2) - n + 1
+**
+** The sqlite3_status() logic tracks the maximum values of n and M so
+** that an application can, at any time, verify this constraint.

+/******************************************************************************
+*************************** Posix Advisory Locking ****************************
+**
+** POSIX advisory locks are broken by design.  ANSI STD 1003.1 (1996)
+** section 6.5.2.2 lines 483 through 490 specify that when a process
+** sets or clears a lock, that operation overrides any prior locks set
+** by the same process.  It does not explicitly say so, but this implies
+** that it overrides locks set by the same process using a different
+** file descriptor.  Consider this test case:
+**
+**       int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
+**       int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
+**
+** Suppose ./file1 and ./file2 are really the same file (because
+** one is a hard or symbolic link to the other) then if you set
+** an exclusive lock on fd1, then try to get an exclusive lock
+** on fd2, it works.  I would have expected the second lock to
+** fail since there was already a lock on the file due to fd1.
+** But not so.  Since both locks came from the same process, the
+** second overrides the first, even though they were on different
+** file descriptors opened on different file names.
+**
+** This means that we cannot use POSIX locks to synchronize file access
+** among competing threads of the same process.  POSIX locks will work fine
+** to synchronize access for threads in separate processes, but not
+** threads within the same process.
+**
+** To work around the problem, SQLite has to manage file locks internally
+** on its own.  Whenever a new database is opened, we have to find the
+** specific inode of the database file (the inode is determined by the
+** st_dev and st_ino fields of the stat structure that fstat() fills in)
+** and check for locks already existing on that inode.  When locks are
+** created or removed, we have to look at our own internal record of the
+** locks to see if another thread has previously set a lock on that same
+** inode.
+**
+** (Aside: The use of inode numbers as unique IDs does not work on VxWorks.
+** For VxWorks, we have to use the alternative unique ID system based on
+** canonical filename and implemented in the previous division.)
+**
+** The sqlite3_file structure for POSIX is no longer just an integer file
+** descriptor.  It is now a structure that holds the integer file
+** descriptor and a pointer to a structure that describes the internal
+** locks on the corresponding inode.  There is one locking structure
+** per inode, so if the same inode is opened twice, both unixFile structures
+** point to the same locking structure.  The locking structure keeps
+** a reference count (so we will know when to delete it) and a "cnt"
+** field that tells us its internal lock status.  cnt==0 means the
+** file is unlocked.  cnt==-1 means the file has an exclusive lock.
+** cnt>0 means there are cnt shared locks on the file.
+**
+** Any attempt to lock or unlock a file first checks the locking
+** structure.  The fcntl() system call is only invoked to set a
+** POSIX lock if the internal lock structure transitions between
+** a locked and an unlocked state.
+**
+** But wait:  there are yet more problems with POSIX advisory locks.
+**
+** If you close a file descriptor that points to a file that has locks,
+** all locks on that file that are owned by the current process are
+** released.  To work around this problem, each unixInodeInfo object
+** maintains a count of the number of pending locks on tha inode.
+** When an attempt is made to close an unixFile, if there are
+** other unixFile open on the same inode that are holding locks, the call
+** to close() the file descriptor is deferred until all of the locks clear.
+** The unixInodeInfo structure keeps a list of file descriptors that need to
+** be closed and that list is walked (and cleared) when the last lock
+** clears.
+**
+** Yet another problem:  LinuxThreads do not play well with posix locks.
+**
+** Many older versions of linux use the LinuxThreads library which is
+** not posix compliant.  Under LinuxThreads, a lock created by thread
+** A cannot be modified or overridden by a different thread B.
+** Only thread A can modify the lock.  Locking behavior is correct
+** if the appliation uses the newer Native Posix Thread Library (NPTL)
+** on linux - with NPTL a lock created by thread A can override locks
+** in thread B.  But there is no way to know at compile-time which
+** threading library is being used.  So there is no way to know at
+** compile-time whether or not thread A can override locks on thread B.
+** One has to do a run-time check to discover the behavior of the
+** current process.
+**
+** SQLite used to support LinuxThreads.  But support for LinuxThreads
+** was dropped beginning with version 3.7.0.  SQLite will still work with
+** LinuxThreads provided that (1) there is no more than one connection
+** per database file in the same process and (2) database connections
+** do not move across threads.

+  **
+  ** Symbols defined in os.h indentify the 'pending byte' and the 'reserved

+  ** range', a range of 510 bytes at a well known offset.
+  **
+  ** To obtain a SHARED lock, a read-lock is obtained on the 'pending
+  ** byte'.  If this is successful, 'shared byte range' is read-locked
+  ** and the lock on the 'pending byte' released.  (Legacy note:  When
+  ** SQLite was first developed, Windows95 systems were still very common,
+  ** and Widnows95 lacks a shared-lock capability.  So on Windows95, a
+  ** single randomly selected by from the 'shared byte range' is locked.
+  ** Windows95 is now pretty much extinct, but this work-around for the
+  ** lack of shared-locks on Windows95 lives on, for backwards
+  ** compatibility.)
+  **
+  ** A process may only obtain a RESERVED lock after it has a SHARED lock.
+  ** A RESERVED lock is implemented by grabbing a write-lock on the
+  ** 'reserved byte'.
+  **
+  ** A process may only obtain a PENDING lock after it has obtained a
+  ** SHARED lock. A PENDING lock is implemented by obtaining a write-lock
+  ** on the 'pending byte'. This ensures that no new SHARED locks can be
+  ** obtained, but existing SHARED locks are allowed to persist. A process
+  ** does not have to obtain a RESERVED lock on the way to a PENDING lock.
+  ** This property is used by the algorithm for rolling back a journal file
+  ** after a crash.
+  **
+  ** An EXCLUSIVE lock, obtained after a PENDING lock is held, is
+  ** implemented by obtaining a write-lock on the entire 'shared byte

+************************** Begin Proxy Locking ********************************
+**
+** Proxy locking is a "uber-locking-method" in this sense:  It uses the
+** other locking methods on secondary lock files.  Proxy locking is a
+** meta-layer over top of the primitive locking implemented above.  For
+** this reason, the division that implements of proxy locking is deferred
+** until late in the file (here) after all of the other I/O methods have
+** been defined - so that the primitive locking methods are available
+** as services to help with the implementation of proxy locking.
+**
+****
+**
+** The default locking schemes in SQLite use byte-range locks on the
+** database file to coordinate safe, concurrent access by multiple readers
+** and writers [http://sqlite.org/lockingv3.html].  The five file locking
+** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
+** as POSIX read & write locks over fixed set of locations (via fsctl),
+** on AFP and SMB only exclusive byte-range locks are available via fsctl
+** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
+** To simulate a F_RDLCK on the shared range, on AFP a randomly selected
+** address in the shared range is taken for a SHARED lock, the entire
+** shared range is taken for an EXCLUSIVE lock):
+**
+**      PENDING_BYTE        0x40000000
+**      RESERVED_BYTE       0x40000001
+**      SHARED_RANGE        0x40000002 -> 0x40000200
+**
+** This works well on the local file system, but shows a nearly 100x
+** slowdown in read performance on AFP because the AFP client disables
+** the read cache when byte-range locks are present.  Enabling the read
+** cache exposes a cache coherency problem that is present on all OS X
+** supported network file systems.  NFS and AFP both observe the
+** close-to-open semantics for ensuring cache coherency
+** [http://nfs.sourceforge.net/#faq_a8], which does not effectively
+** address the requirements for concurrent database access by multiple
+** readers and writers
+** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
+**
+** To address the performance and cache coherency issues, proxy file locking
+** changes the way database access is controlled by limiting access to a
+** single host at a time and moving file locks off of the database file
+** and onto a proxy file on the local file system.
+**
+**
+** Using proxy locks
+** -----------------
+**
+** C APIs
+**
+**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_SET_LOCKPROXYFILE,
+**                       <proxy_path> | ":auto:");
+**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_GET_LOCKPROXYFILE,
+**                       &<proxy_path>);
+**
+**
+** SQL pragmas
+**
+**  PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
+**  PRAGMA [database.]lock_proxy_file
+**
+** Specifying ":auto:" means that if there is a conch file with a matching
+** host ID in it, the proxy path in the conch file will be used, otherwise
+** a proxy path based on the user's temp dir
+** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
+** actual proxy file name is generated from the name and path of the
+** database file.  For example:
+**
+**       For database path "/Users/me/foo.db"
+**       The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
+**
+** Once a lock proxy is configured for a database connection, it can not
+** be removed, however it may be switched to a different proxy path via
+** the above APIs (assuming the conch file is not being held by another
+** connection or process).
+**
+**
+** How proxy locking works
+** -----------------------
+**
+** Proxy file locking relies primarily on two new supporting files:
+**
+**   *  conch file to limit access to the database file to a single host
+**      at a time
+**
+**   *  proxy file to act as a proxy for the advisory locks normally
+**      taken on the database
+**
+** The conch file - to use a proxy file, sqlite must first "hold the conch"
+** by taking an sqlite-style shared lock on the conch file, reading the
+** contents and comparing the host's unique host ID (see below) and lock
+** proxy path against the values stored in the conch.  The conch file is
+** stored in the same directory as the database file and the file name
+** is patterned after the database file name as ".<databasename>-conch".
+** If the conch file does not exist, or its contents do not match the
+** host ID and/or proxy path, then the lock is escalated to an exclusive
+** lock and the conch file contents is updated with the host ID and proxy
+** path and the lock is downgraded to a shared lock again.  If the conch
+** is held by another process (with a shared lock), the exclusive lock
+** will fail and SQLITE_BUSY is returned.
+**
+** The proxy file - a single-byte file used for all advisory file locks
+** normally taken on the database file.   This allows for safe sharing
+** of the database file for multiple readers and writers on the same
+** host (the conch ensures that they all use the same local lock file).
+**
+** Requesting the lock proxy does not immediately take the conch, it is
+** only taken when the first request to lock database file is made.
+** This matches the semantics of the traditional locking behavior, where
+** opening a connection to a database file does not take a lock on it.
+** The shared lock and an open file descriptor are maintained until
+** the connection to the database is closed.
+**
+** The proxy file and the lock file are never deleted so they only need
+** to be created the first time they are used.
+**
+** Configuration options
+** ---------------------
+**
+**  SQLITE_PREFER_PROXY_LOCKING
+**
+**       Database files accessed on non-local file systems are
+**       automatically configured for proxy locking, lock files are
+**       named automatically using the same logic as
+**       PRAGMA lock_proxy_file=":auto:"
+**
+**  SQLITE_PROXY_DEBUG
+**
+**       Enables the logging of error messages during host id file
+**       retrieval and creation
+**
+**  LOCKPROXYDIR
+**
+**       Overrides the default directory used for lock proxy files that
+**       are named automatically via the ":auto:" setting
+**
+**  SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
+**
+**       Permissions to use when creating a directory for storing the
+**       lock proxy files, only used when LOCKPROXYDIR is not set.
+**
+**
+** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
+** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
+** force proxy locking to be used for every database file opened, and 0
+** will force automatic proxy locking to be disabled for all database
+** files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or
+** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).

+** The idea is that this function works like a combination of
+** GetLastError() and FormatMessage() on Windows (or errno and
+** strerror_r() on Unix). After an error is returned by an OS
+** function, SQLite calls this function with zBuf pointing to
+** a buffer of nBuf bytes. The OS layer should populate the
+** buffer with a nul-terminated UTF-8 encoded error message
+** describing the last IO error to have occurred within the calling
+** thread.
+**
+** If the error message is too large for the supplied buffer,
+** it should be truncated. The return value of xGetLastError
+** is zero if the error message fits in the buffer, or non-zero
+** otherwise (if the message was truncated). If non-zero is returned,
+** then it is not necessary to include the nul-terminator character
+** in the output buffer.
+**
+** Not supplying an error message will have no adverse effect
+** on SQLite. It is fine to have an implementation that never
+** returns an error message:
+**
+**   int xGetLastError(sqlite3_vfs *pVfs, int nBuf, char *zBuf){
+**     assert(zBuf[0]=='\0');
+**     return 0;

+**
+** However if an error message is supplied, it will be incorporated
+** by sqlite into the error message available to the user using
+** sqlite3_errmsg(), possibly making IO errors easier to debug.

+** So the bitmap is usually sparse and has low cardinality.

+** to handle both cases well.
+**
+** The size of the bitmap is fixed when the object is created.

+**
+** This file implements the default page cache implementation (the
+** sqlite3_pcache interface). It also contains part of the implementation
+** of the SQLITE_CONFIG_PAGECACHE and sqlite3_release_memory() features.
+** If the default page cache implementation is overridden, then neither of
+** these two features are available.
+**
+** A Page cache line looks like this:
+**
+**  -------------------------------------------------------------
+**  |  database page content   |  PgHdr1  |  MemPage  |  PgHdr  |
+**  -------------------------------------------------------------
+**
+** The database page content is up front (so that buffer overreads tend to
+** flow harmlessly into the PgHdr1, MemPage, and PgHdr extensions).   MemPage
+** is the extension added by the btree.c module containing information such
+** as the database page number and how that database page is used.  PgHdr
+** is added by the pcache.c layer and contains information used to keep track
+** of which pages are "dirty".  PgHdr1 is an extension added by this
+** module (pcache1.c).  The PgHdr1 header is a subclass of sqlite3_pcache_page.
+** PgHdr1 contains information needed to look up a page by its page number.
+** The superclass sqlite3_pcache_page.pBuf points to the start of the
+** database page content and sqlite3_pcache_page.pExtra points to PgHdr.
+**
+** The size of the extension (MemPage+PgHdr+PgHdr1) can be determined at
+** runtime using sqlite3_config(SQLITE_CONFIG_PCACHE_HDRSZ, &size).  The
+** sizes of the extensions sum to 272 bytes on x64 for 3.8.10, but this
+** size can vary according to architecture, compile-time options, and
+** SQLite library version number.
+**
+** If SQLITE_PCACHE_SEPARATE_HEADER is defined, then the extension is obtained
+** using a separate memory allocation from the database page content.  This
+** seeks to overcome the "clownshoe" problem (also called "internal
+** fragmentation" in academic literature) of allocating a few bytes more
+** than a power of two with the memory allocator rounding up to the next
+** power of two, and leaving the rounded-up space unused.
+**
+** This module tracks pointers to PgHdr1 objects.  Only pcache.c communicates
+** with this module.  Information is passed back and forth as PgHdr1 pointers.
+**
+** The pcache.c and pager.c modules deal pointers to PgHdr objects.
+** The btree.c module deals with pointers to MemPage objects.
+**
+** SOURCE OF PAGE CACHE MEMORY:
+**
+** Memory for a page might come from any of three sources:
+**
+**    (1)  The general-purpose memory allocator - sqlite3Malloc()
+**    (2)  Global page-cache memory provided using sqlite3_config() with
+**         SQLITE_CONFIG_PAGECACHE.
+**    (3)  PCache-local bulk allocation.
+**
+** The third case is a chunk of heap memory (defaulting to 100 pages worth)
+** that is allocated when the page cache is created.  The size of the local
+** bulk allocation can be adjusted using
+**
+**     sqlite3_config(SQLITE_CONFIG_PAGECACHE, (void*)0, 0, N).
+**
+** If N is positive, then N pages worth of memory are allocated using a single
+** sqlite3Malloc() call and that memory is used for the first N pages allocated.
+** Or if N is negative, then -1024*N bytes of memory are allocated and used
+** for as many pages as can be accomodated.
+**
+** Only one of (2) or (3) can be used.  Once the memory available to (2) or
+** (3) is exhausted, subsequent allocations fail over to the general-purpose
+** memory allocator (1).
+**
+** Earlier versions of SQLite used only methods (1) and (2).  But experiments
+** show that method (3) with N==100 provides about a 5% performance boost for
+** common workloads.

+** Implementation of the sqlite3_pcache.xFetch method.

+** Fetch a page by key value.
+**
+** Whether or not a new page may be allocated by this function depends on
+** the value of the createFlag argument.  0 means do not allocate a new
+** page.  1 means allocate a new page if space is easily available.  2
+** means to try really hard to allocate a new page.
+**
+** For a non-purgeable cache (a cache used as the storage for an in-memory
+** database) there is really no difference between createFlag 1 and 2.  So
+** the calling function (pcache.c) will never have a createFlag of 1 on
+** a non-purgeable cache.
+**
+** There are three different approaches to obtaining space for a page,
+** depending on the value of parameter createFlag (which may be 0, 1 or 2).
+**
+**   1. Regardless of the value of createFlag, the cache is searched for a
+**      copy of the requested page. If one is found, it is returned.
+**
+**   2. If createFlag==0 and the page is not already in the cache, NULL is
+**      returned.
+**
+**   3. If createFlag is 1, and the page is not already in the cache, then
+**      return NULL (do not allocate a new page) if any of the following
+**      conditions are true:
+**
+**       (a) the number of pages pinned by the cache is greater than
+**           PCache1.nMax, or
+**
+**       (b) the number of pages pinned by the cache is greater than
+**           the sum of nMax for all purgeable caches, less the sum of
+**           nMin for all other purgeable caches, or
+**
+**   4. If none of the first three conditions apply and the cache is marked
+**      as purgeable, and if one of the following is true:
+**
+**       (a) The number of pages allocated for the cache is already
+**           PCache1.nMax, or
+**
+**       (b) The number of pages allocated for all purgeable caches is
+**           already equal to or greater than the sum of nMax for all
+**           purgeable caches,
+**
+**       (c) The system is under memory pressure and wants to avoid
+**           unnecessary pages cache entry allocations
+**
+**      then attempt to recycle a page from the LRU list. If it is the right
+**      size, return the recycled buffer. Otherwise, free the buffer and

+*************************************************************************
+**
+** This module implements an object we call a "RowSet".
+**
+** The RowSet object is a collection of rowids.  Rowids
+** are inserted into the RowSet in an arbitrary order.  Inserts
+** can be intermixed with tests to see if a given rowid has been
+** previously inserted into the RowSet.
+**
+** After all inserts are finished, it is possible to extract the
+** elements of the RowSet in sorted order.  Once this extraction
+** process has started, no new elements may be inserted.
+**
+** Hence, the primitive operations for a RowSet are:
+**
+**    CREATE
+**    INSERT
+**    TEST
+**    SMALLEST
+**    DESTROY
+**
+** The CREATE and DESTROY primitives are the constructor and destructor,
+** obviously.  The INSERT primitive adds a new element to the RowSet.
+** TEST checks to see if an element is already in the RowSet.  SMALLEST
+** extracts the least value from the RowSet.
+**
+** The INSERT primitive might allocate additional memory.  Memory is
+** allocated in chunks so most INSERTs do no allocation.  There is an
+** upper bound on the size of allocated memory.  No memory is freed
+** until DESTROY.
+**
+** The TEST primitive includes a "batch" number.  The TEST primitive
+** will only see elements that were inserted before the last change
+** in the batch number.  In other words, if an INSERT occurs between
+** two TESTs where the TESTs have the same batch nubmer, then the
+** value added by the INSERT will not be visible to the second TEST.
+** The initial batch number is zero, so if the very first TEST contains
+** a non-zero batch number, it will see all prior INSERTs.
+**
+** No INSERTs may occurs after a SMALLEST.  An assertion will fail if
+** that is attempted.
+**
+** The cost of an INSERT is roughly constant.  (Sometimes new memory
+** has to be allocated on an INSERT.)  The cost of a TEST with a new
+** batch number is O(NlogN) where N is the number of elements in the RowSet.
+** The cost of a TEST using the same batch number is O(logN).  The cost
+** of the first SMALLEST is O(NlogN).  Second and subsequent SMALLEST
+** primitives are constant time.  The cost of DESTROY is O(N).
+**
+** TEST and SMALLEST may not be used by the same RowSet.  This used to
+** be possible, but the feature was not used, so it was removed in order
+** to simplify the code.

+/******************* NOTES ON THE DESIGN OF THE PAGER ************************
+**
+** This comment block describes invariants that hold when using a rollback
+** journal.  These invariants do not apply for journal_mode=WAL,
+** journal_mode=MEMORY, or journal_mode=OFF.
+**
+** Within this comment block, a page is deemed to have been synced
+** automatically as soon as it is written when PRAGMA synchronous=OFF.
+** Otherwise, the page is not synced until the xSync method of the VFS
+** is called successfully on the file containing the page.
+**
+** Definition:  A page of the database file is said to be "overwriteable" if
+** one or more of the following are true about the page:
+**
+**     (a)  The original content of the page as it was at the beginning of
+**          the transaction has been written into the rollback journal and
+**          synced.
+**
+**     (b)  The page was a freelist leaf page at the start of the transaction.
+**
+**     (c)  The page number is greater than the largest page that existed in
+**          the database file at the start of the transaction.
+**
+** (1) A page of the database file is never overwritten unless one of the
+**     following are true:
+**
+**     (a) The page and all other pages on the same sector are overwriteable.
+**
+**     (b) The atomic page write optimization is enabled, and the entire
+**         transaction other than the update of the transaction sequence
+**         number consists of a single page change.
+**
+** (2) The content of a page written into the rollback journal exactly matches
+**     both the content in the database when the rollback journal was written
+**     and the content in the database at the beginning of the current
+**     transaction.
+**
+** (3) Writes to the database file are an integer multiple of the page size
+**     in length and are aligned on a page boundary.
+**
+** (4) Reads from the database file are either aligned on a page boundary and
+**     an integer multiple of the page size in length or are taken from the
+**     first 100 bytes of the database file.
+**
+** (5) All writes to the database file are synced prior to the rollback journal
+**     being deleted, truncated, or zeroed.
+**
+** (6) If a super-journal file is used, then all writes to the database file
+**     are synced prior to the super-journal being deleted.
+**
+** Definition: Two databases (or the same database at two points it time)
+** are said to be "logically equivalent" if they give the same answer to
+** all queries.  Note in particular the content of freelist leaf
+** pages can be changed arbitrarily without affecting the logical equivalence
+** of the database.
+**
+** (7) At any time, if any subset, including the empty set and the total set,
+**     of the unsynced changes to a rollback journal are removed and the
+**     journal is rolled back, the resulting database file will be logically
+**     equivalent to the database file at the beginning of the transaction.
+**
+** (8) When a transaction is rolled back, the xTruncate method of the VFS
+**     is called to restore the database file to the same size it was at
+**     the beginning of the transaction.  (In some VFSes, the xTruncate
+**     method is a no-op, but that does not change the fact the SQLite will
+**     invoke it.)
+**
+** (9) Whenever the database file is modified, at least one bit in the range
+**     of bytes from 24 through 39 inclusive will be changed prior to releasing
+**     the EXCLUSIVE lock, thus signaling other connections on the same
+**     database to flush their caches.
+**
+** (10) The pattern of bits in bytes 24 through 39 shall not repeat in less

+**
+**
+**  OPEN:
+**
+**    The pager starts up in this state. Nothing is guaranteed in this
+**    state - the file may or may not be locked and the database size is
+**    unknown. The database may not be read or written.
+**
+**    * No read or write transaction is active.
+**    * Any lock, or no lock at all, may be held on the database file.
+**    * The dbSize, dbOrigSize and dbFileSize variables may not be trusted.
+**
+**  READER:
+**
+**    In this state all the requirements for reading the database in
+**    rollback (non-WAL) mode are met. Unless the pager is (or recently
+**    was) in exclusive-locking mode, a user-level read transaction is
+**    open. The database size is known in this state.
+**
+**    A connection running with locking_mode=normal enters this state when
+**    it opens a read-transaction on the database and returns to state
+**    OPEN after the read-transaction is completed. However a connection
+**    running in locking_mode=exclusive (including temp databases) remains in
+**    this state even after the read-transaction is closed. The only way
+**    a locking_mode=exclusive connection can transition from READER to OPEN
+**    is via the ERROR state (see below).
+**
+**    * A read transaction may be active (but a write-transaction cannot).
+**    * A SHARED or greater lock is held on the database file.
+**    * The dbSize variable may be trusted (even if a user-level read
+**      transaction is not active). The dbOrigSize and dbFileSize variables
+**      may not be trusted at this point.
+**    * If the database is a WAL database, then the WAL connection is open.
+**    * Even if a read-transaction is not open, it is guaranteed that
+**      there is no hot-journal in the file-system.
+**
+**  WRITER_LOCKED:
+**
+**    The pager moves to this state from READER when a write-transaction
+**    is first opened on the database. In WRITER_LOCKED state, all locks
+**    required to start a write-transaction are held, but no actual
+**    modifications to the cache or database have taken place.
+**
+**    In rollback mode, a RESERVED or (if the transaction was opened with
+**    BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
+**    moving to this state, but the journal file is not written to or opened
+**    to in this state. If the transaction is committed or rolled back while
+**    in WRITER_LOCKED state, all that is required is to unlock the database
+**    file.
+**
+**    IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
+**    If the connection is running with locking_mode=exclusive, an attempt
+**    is made to obtain an EXCLUSIVE lock on the database file.
+**
+**    * A write transaction is active.
+**    * If the connection is open in rollback-mode, a RESERVED or greater
+**      lock is held on the database file.
+**    * If the connection is open in WAL-mode, a WAL write transaction
+**      is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
+**      called).
+**    * The dbSize, dbOrigSize and dbFileSize variables are all valid.
+**    * The contents of the pager cache have not been modified.
+**    * The journal file may or may not be open.
+**    * Nothing (not even the first header) has been written to the journal.
+**
+**  WRITER_CACHEMOD:
+**
+**    A pager moves from WRITER_LOCKED state to this state when a page is
+**    first modified by the upper layer. In rollback mode the journal file
+**    is opened (if it is not already open) and a header written to the
+**    start of it. The database file on disk has not been modified.
+**
+**    * A write transaction is active.
+**    * A RESERVED or greater lock is held on the database file.
+**    * The journal file is open and the first header has been written
+**      to it, but the header has not been synced to disk.
+**    * The contents of the page cache have been modified.
+**
+**  WRITER_DBMOD:
+**
+**    The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
+**    when it modifies the contents of the database file. WAL connections
+**    never enter this state (since they do not modify the database file,
+**    just the log file).
+**
+**    * A write transaction is active.
+**    * An EXCLUSIVE or greater lock is held on the database file.
+**    * The journal file is open and the first header has been written
+**      and synced to disk.
+**    * The contents of the page cache have been modified (and possibly
+**      written to disk).
+**
+**  WRITER_FINISHED:
+**
+**    It is not possible for a WAL connection to enter this state.
+**
+**    A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
+**    state after the entire transaction has been successfully written into the
+**    database file. In this state the transaction may be committed simply
+**    by finalizing the journal file. Once in WRITER_FINISHED state, it is
+**    not possible to modify the database further. At this point, the upper
+**    layer must either commit or rollback the transaction.
+**
+**    * A write transaction is active.
+**    * An EXCLUSIVE or greater lock is held on the database file.
+**    * All writing and syncing of journal and database data has finished.
+**      If no error occurred, all that remains is to finalize the journal to
+**      commit the transaction. If an error did occur, the caller will need
+**      to rollback the transaction.
+**
+**  ERROR:
+**
+**    The ERROR state is entered when an IO or disk-full error (including
+**    SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it
+**    difficult to be sure that the in-memory pager state (cache contents,
+**    db size etc.) are consistent with the contents of the file-system.
+**
+**    Temporary pager files may enter the ERROR state, but in-memory pagers
+**    cannot.
+**
+**    For example, if an IO error occurs while performing a rollback,
+**    the contents of the page-cache may be left in an inconsistent state.
+**    At this point it would be dangerous to change back to READER state
+**    (as usually happens after a rollback). Any subsequent readers might
+**    report database corruption (due to the inconsistent cache), and if
+**    they upgrade to writers, they may inadvertently corrupt the database
+**    file. To avoid this hazard, the pager switches into the ERROR state
+**    instead of READER following such an error.
+**
+**    Once it has entered the ERROR state, any attempt to use the pager
+**    to read or write data returns an error. Eventually, once all
+**    outstanding transactions have been abandoned, the pager is able to
+**    transition back to OPEN state, discarding the contents of the
+**    page-cache and any other in-memory state at the same time. Everything
+**    is reloaded from disk (and, if necessary, hot-journal rollback peformed)
+**    when a read-transaction is next opened on the pager (transitioning
+**    the pager into READER state). At that point the system has recovered
+**    from the error.
+**
+**    Specifically, the pager jumps into the ERROR state if:
+**
+**      1. An error occurs while attempting a rollback. This happens in
+**         function sqlite3PagerRollback().
+**
+**      2. An error occurs while attempting to finalize a journal file
+**         following a commit in function sqlite3PagerCommitPhaseTwo().
+**
+**      3. An error occurs while attempting to write to the journal or
+**         database file in function pagerStress() in order to free up
+**         memory.
+**
+**    In other cases, the error is returned to the b-tree layer. The b-tree
+**    layer then attempts a rollback operation. If the error condition
+**    persists, the pager enters the ERROR state via condition (1) above.
+**
+**    Condition (3) is necessary because it can be triggered by a read-only
+**    statement executed within a transaction. In this case, if the error
+**    code were simply returned to the user, the b-tree layer would not
+**    automatically attempt a rollback, as it assumes that an error in a
+**    read-only statement cannot leave the pager in an internally inconsistent
+**    state.
+**
+**    * The Pager.errCode variable is set to something other than SQLITE_OK.
+**    * There are one or more outstanding references to pages (after the
+**      last reference is dropped the pager should move back to OPEN state).
+**    * The pager is not an in-memory pager.
+**
+**
+** Notes:
+**
+**   * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
+**     connection is open in WAL mode. A WAL connection is always in one
+**     of the first four states.
+**
+**   * Normally, a connection open in exclusive mode is never in PAGER_OPEN
+**     state. There are two exceptions: immediately after exclusive-mode has
+**     been turned on (and before any read or write transactions are
+**     executed), and when the pager is leaving the "error state".
+**
+**   * See also: assert_pager_state().

+** The Pager.eLock variable is almost always set to one of the
+** following locking-states, according to the lock currently held on
+** the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
+** This variable is kept up to date as locks are taken and released by
+** the pagerLockDb() and pagerUnlockDb() wrappers.
+**
+** If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
+** (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
+** the operation was successful. In these circumstances pagerLockDb() and
+** pagerUnlockDb() take a conservative approach - eLock is always updated
+** when unlocking the file, and only updated when locking the file if the
+** VFS call is successful. This way, the Pager.eLock variable may be set
+** to a less exclusive (lower) value than the lock that is actually held
+** at the system level, but it is never set to a more exclusive value.
+**
+** This is usually safe. If an xUnlock fails or appears to fail, there may
+** be a few redundant xLock() calls or a lock may be held for longer than
+** required, but nothing really goes wrong.
+**
+** The exception is when the database file is unlocked as the pager moves
+** from ERROR to OPEN state. At this point there may be a hot-journal file
+** in the file-system that needs to be rolled back (as part of an OPEN->SHARED
+** transition, by the same pager or any other). If the call to xUnlock()
+** fails at this point and the pager is left holding an EXCLUSIVE lock, this
+** can confuse the call to xCheckReservedLock() call made later as part
+** of hot-journal detection.
+**
+** xCheckReservedLock() is defined as returning true "if there is a RESERVED
+** lock held by this process or any others". So xCheckReservedLock may
+** return true because the caller itself is holding an EXCLUSIVE lock (but
+** doesn't know it because of a previous error in xUnlock). If this happens
+** a hot-journal may be mistaken for a journal being created by an active
+** transaction in another process, causing SQLite to read from the database
+** without rolling it back.
+**
+** To work around this, if a call to xUnlock() fails when unlocking the
+** database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
+** is only changed back to a real locking state after a successful call
+** to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
+** omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK
+** lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
+** lock on the database file before attempting to roll it back. See function
+** PagerSharedLock() for more detail.

+** An open page cache is an instance of struct Pager. A description of
+** some of the more important member variables follows:
+**
+** eState
+**
+**   The current 'state' of the pager object. See the comment and state
+**   diagram above for a description of the pager state.
+**
+** eLock
+**
+**   For a real on-disk database, the current lock held on the database file -
+**   NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
+**
+**   For a temporary or in-memory database (neither of which require any
+**   locks), this variable is always set to EXCLUSIVE_LOCK. Since such
+**   databases always have Pager.exclusiveMode==1, this tricks the pager
+**   logic into thinking that it already has all the locks it will ever
+**   need (and no reason to release them).
+**
+**   In some (obscure) circumstances, this variable may also be set to
+**   UNKNOWN_LOCK. See the comment above the #define of UNKNOWN_LOCK for
+**   details.
+**
+** changeCountDone
+**
+**   This boolean variable is used to make sure that the change-counter
+**   (the 4-byte header field at byte offset 24 of the database file) is
+**   not updated more often than necessary.
+**
+**   It is set to true when the change-counter field is updated, which
+**   can only happen if an exclusive lock is held on the database file.
+**   It is cleared (set to false) whenever an exclusive lock is
+**   relinquished on the database file. Each time a transaction is committed,
+**   The changeCountDone flag is inspected. If it is true, the work of
+**   updating the change-counter is omitted for the current transaction.
+**
+**   This mechanism means that when running in exclusive mode, a connection
+**   need only update the change-counter once, for the first transaction
+**   committed.
+**
+** setSuper
+**
+**   When PagerCommitPhaseOne() is called to commit a transaction, it may
+**   (or may not) specify a super-journal name to be written into the
+**   journal file before it is synced to disk.
+**
+**   Whether or not a journal file contains a super-journal pointer affects
+**   the way in which the journal file is finalized after the transaction is
+**   committed or rolled back when running in "journal_mode=PERSIST" mode.
+**   If a journal file does not contain a super-journal pointer, it is
+**   finalized by overwriting the first journal header with zeroes. If
+**   it does contain a super-journal pointer the journal file is finalized
+**   by truncating it to zero bytes, just as if the connection were
+**   running in "journal_mode=truncate" mode.
+**
+**   Journal files that contain super-journal pointers cannot be finalized
+**   simply by overwriting the first journal-header with zeroes, as the
+**   super-journal pointer could interfere with hot-journal rollback of any
+**   subsequently interrupted transaction that reuses the journal file.
+**
+**   The flag is cleared as soon as the journal file is finalized (either
+**   by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the
+**   journal file from being successfully finalized, the setSuper flag
+**   is cleared anyway (and the pager will move to ERROR state).
+**
+** doNotSpill
+**
+**   This variables control the behavior of cache-spills  (calls made by
+**   the pcache module to the pagerStress() routine to write cached data
+**   to the file-system in order to free up memory).
+**
+**   When bits SPILLFLAG_OFF or SPILLFLAG_ROLLBACK of doNotSpill are set,
+**   writing to the database from pagerStress() is disabled altogether.
+**   The SPILLFLAG_ROLLBACK case is done in a very obscure case that
+**   comes up during savepoint rollback that requires the pcache module
+**   to allocate a new page to prevent the journal file from being written
+**   while it is being traversed by code in pager_playback().  The SPILLFLAG_OFF
+**   case is a user preference.
+**
+**   If the SPILLFLAG_NOSYNC bit is set, writing to the database from
+**   pagerStress() is permitted, but syncing the journal file is not.
+**   This flag is set by sqlite3PagerWrite() when the file-system sector-size
+**   is larger than the database page-size in order to prevent a journal sync
+**   from happening in between the journalling of two pages on the same sector.
+**
+** subjInMemory
+**
+**   This is a boolean variable. If true, then any required sub-journal
+**   is opened as an in-memory journal file. If false, then in-memory
+**   sub-journals are only used for in-memory pager files.
+**
+**   This variable is updated by the upper layer each time a new
+**   write-transaction is opened.
+**
+** dbSize, dbOrigSize, dbFileSize
+**
+**   Variable dbSize is set to the number of pages in the database file.
+**   It is valid in PAGER_READER and higher states (all states except for
+**   OPEN and ERROR).
+**
+**   dbSize is set based on the size of the database file, which may be
+**   larger than the size of the database (the value stored at offset
+**   28 of the database header by the btree). If the size of the file
+**   is not an integer multiple of the page-size, the value stored in
+**   dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2).
+**   Except, any file that is greater than 0 bytes in size is considered
+**   to have at least one page. (i.e. a 1KB file with 2K page-size leads
+**   to dbSize==1).
+**
+**   During a write-transaction, if pages with page-numbers greater than
+**   dbSize are modified in the cache, dbSize is updated accordingly.
+**   Similarly, if the database is truncated using PagerTruncateImage(),
+**   dbSize is updated.
+**
+**   Variables dbOrigSize and dbFileSize are valid in states
+**   PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize
+**   variable at the start of the transaction. It is used during rollback,
+**   and to determine whether or not pages need to be journalled before
+**   being modified.
+**
+**   Throughout a write-transaction, dbFileSize contains the size of
+**   the file on disk in pages. It is set to a copy of dbSize when the
+**   write-transaction is first opened, and updated when VFS calls are made
+**   to write or truncate the database file on disk.
+**
+**   The only reason the dbFileSize variable is required is to suppress
+**   unnecessary calls to xTruncate() after committing a transaction. If,
+**   when a transaction is committed, the dbFileSize variable indicates
+**   that the database file is larger than the database image (Pager.dbSize),
+**   pager_truncate() is called. The pager_truncate() call uses xFilesize()
+**   to measure the database file on disk, and then truncates it if required.
+**   dbFileSize is not used when rolling back a transaction. In this case
+**   pager_truncate() is called unconditionally (which means there may be
+**   a call to xFilesize() that is not strictly required). In either case,
+**   pager_truncate() may cause the file to become smaller or larger.
+**
+** dbHintSize
+**
+**   The dbHintSize variable is used to limit the number of calls made to
+**   the VFS xFileControl(FCNTL_SIZE_HINT) method.
+**
+**   dbHintSize is set to a copy of the dbSize variable when a

+**
+** errCode
+**
+**   The Pager.errCode variable is only ever used in PAGER_ERROR state. It
+**   is set to zero in all other states. In PAGER_ERROR state, Pager.errCode
+**   is always set to SQLITE_FULL, SQLITE_IOERR or one of the SQLITE_IOERR_XXX
+**   sub-codes.
+**
+** syncFlags, walSyncFlags
+**
+**   syncFlags is either SQLITE_SYNC_NORMAL (0x02) or SQLITE_SYNC_FULL (0x03).
+**   syncFlags is used for rollback mode.  walSyncFlags is used for WAL mode
+**   and contains the flags used to sync the checkpoint operations in the
+**   lower two bits, and sync flags used for transaction commits in the WAL
+**   file in bits 0x04 and 0x08.  In other words, to get the correct sync flags
+**   for checkpoint operations, use (walSyncFlags&0x03) and to get the correct
+**   sync flags for transaction commit, use ((walSyncFlags>>2)&0x03).  Note
+**   that with synchronous=NORMAL in WAL mode, transaction commit is not synced
+**   meaning that the 0x04 and 0x08 bits are both zero.

+**     Journal file descriptor is simply closed. This destroys an
+**     in-memory journal.

+**   journalMode==TRUNCATE
+**     Journal file is truncated to zero bytes in size.
+**
+**   journalMode==PERSIST
+**     The first 28 bytes of the journal file are zeroed. This invalidates
+**     the first journal header in the file, and hence the entire journal
+**     file. An invalid journal file cannot be rolled back.
+**
+**   journalMode==DELETE
+**     The journal file is closed and deleted using sqlite3OsDelete().
+**
+**     If the pager is running in exclusive mode, this method of finalizing
+**     the journal file is never used. Instead, if the journalMode is
+**     DELETE and the pager is in exclusive mode, the method described under
+**     journalMode==PERSIST is used instead.
+**
+** After the journal is finalized, the pager moves to PAGER_READER state.
+** If running in non-exclusive rollback mode, the lock on the file is
+** downgraded to a SHARED_LOCK.
+**
+** SQLITE_OK is returned if no error occurs. If an error occurs during
+** any of the IO operations to finalize the journal file or unlock the
+** database then the IO error code is returned to the user. If the
+** operation to finalize the journal file fails, then the code still
+** tries to unlock the database file if not in exclusive mode. If the

+** the state it was in before we started making changes.
+**
+** The journal file format is as follows:
+**
+**  (1)  8 byte prefix.  A copy of aJournalMagic[].
+**  (2)  4 byte big-endian integer which is the number of valid page records
+**       in the journal.  If this value is 0xffffffff, then compute the
+**       number of page records from the journal size.
+**  (3)  4 byte big-endian integer which is the initial value for the
+**       sanity checksum.
+**  (4)  4 byte integer which is the number of pages to truncate the
+**       database to during a rollback.
+**  (5)  4 byte big-endian integer which is the sector size.  The header
+**       is this many bytes in size.
+**  (6)  4 byte big-endian integer which is the page size.
+**  (7)  zero padding out to the next sector size.
+**  (8)  Zero or more pages instances, each as follows:
+**        +  4 byte page number.
+**        +  pPager->pageSize bytes of data.
+**        +  4 byte checksum
+**
+** When we speak of the journal header, we mean the first 7 items above.
+** Each entry in the journal is an instance of the 8th item.
+**
+** Call the value from the second bullet "nRec".  nRec is the number of
+** valid page entries in the journal.  In most cases, you can compute the
+** value of nRec from the size of the journal file.  But if a power
+** failure occurred while the journal was being written, it could be the
+** case that the size of the journal file had already been increased but
+** the extra entries had not yet made it safely to disk.  In such a case,
+** the value of nRec computed from the file size would be too large.  For
+** that reason, we always use the nRec value in the header.
+**
+** If the nRec value is 0xffffffff it means that nRec should be computed
+** from the file size.  This value is used when the user selects the
+** no-sync option for the journal.  A power failure could lead to corruption
+** in this case.  But for things like temporary table (which will be
+** deleted when the power is restored) we don't care.
+**
+** If the file opened as the journal file is not a well-formed
+** journal file then all pages up to the first corrupted page are rolled
+** back (or no pages if the journal header is corrupted). The journal file
+** is then deleted and SQLITE_OK returned, just as if no corruption had
+** been encountered.
+**
+** If an I/O or malloc() error occurs, the journal-file is not deleted
+** and an error code is returned.
+**
+** The isHot parameter indicates that we are trying to rollback a journal
+** that might be a hot journal.  Or, it could be that the journal is
+** preserved because of JOURNALMODE_PERSIST or JOURNALMODE_TRUNCATE.
+** If the journal really is hot, reset the pager cache prior rolling
+** back any content.  If the journal is merely persistent, no reset is
+** needed.

+** The "level" in pgFlags & PAGER_SYNCHRONOUS_MASK sets the robustness

+** changing the number of syncs()s when writing the journals.
+** There are four levels:
+**
+**    OFF       sqlite3OsSync() is never called.  This is the default
+**              for temporary and transient files.
+**
+**    NORMAL    The journal is synced once before writes begin on the
+**              database.  This is normally adequate protection, but
+**              it is theoretically possible, though very unlikely,
+**              that an inopertune power failure could leave the journal
+**              in a state which would cause damage to the database
+**              when it is rolled back.
+**
+**    FULL      The journal is synced twice before writes begin on the
+**              database (with some additional information - the nRec field
+**              of the journal header - being written in between the two
+**              syncs).  If we assume that writing a
+**              single disk sector is atomic, then this mode provides
+**              assurance that the journal will not be corrupted to the
+**              point of causing damage to the database during rollback.
+**
+**    EXTRA     This is like FULL except that is also syncs the directory
+**              that contains the rollback journal after the rollback
+**              journal is unlinked.
+**
+** The above is for a rollback-journal mode.  For WAL mode, OFF continues
+** to mean that no syncs ever occur.  NORMAL means that the WAL is synced
+** prior to the start of checkpoint and that the database file is synced
+** at the conclusion of the checkpoint if the entire content of the WAL
+** was written back into the database.  But no sync operations occur for
+** an ordinary commit in NORMAL mode with WAL.  FULL means that the WAL
+** file is synced following each commit operation, in addition to the
+** syncs associated with NORMAL.  There is no difference between FULL
+** and EXTRA for WAL mode.
+**
+** Do not confuse synchronous=FULL with SQLITE_SYNC_FULL.  The
+** SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
+** using fcntl(F_FULLFSYNC).  SQLITE_SYNC_NORMAL means to do an
+** ordinary fsync() call.  There is no difference between SQLITE_SYNC_FULL
+** and SQLITE_SYNC_NORMAL on platforms other than MacOSX.  But the
+** synchronous=FULL versus synchronous=NORMAL setting determines when
+** the xSync primitive is called and is relevant to all platforms.
+**
+** Numeric values associated with these states are OFF==1, NORMAL=2,
+** and FULL=3.

+** Otherwise, a new page object is allocated and populated with data
+** read from the database file. In some cases, the pcache module may
+** choose not to allocate a new page object and may reuse an existing
+** object with no outstanding references.
+**
+** The extra data appended to a page is always initialized to zeros the
+** first time a page is loaded into memory. If the page requested is
+** already in the cache when this function is called, then the extra
+** data is left as it was when the page object was last used.
+**
+** If the database image is smaller than the requested page or if
+** the flags parameter contains the PAGER_GET_NOCONTENT bit and the
+** requested page is not already stored in the cache, then no
+** actual disk read occurs. In this case the memory image of the
+** page is initialized to all zeros.
+**
+** If PAGER_GET_NOCONTENT is true, it means that we do not care about
+** the contents of the page. This occurs in two scenarios:
+**
+**   a) When reading a free-list leaf page from the database, and
+**
+**   b) When a savepoint is being rolled back and we need to load
+**      a new page into the cache to be filled with the data read
+**      from the savepoint journal.
+**
+** If PAGER_GET_NOCONTENT is true, then the data returned is zeroed instead
+** of being read from the database. Additionally, the bits corresponding
+** to pgno in Pager.pInJournal (bitvec of pages already written to the
+** journal file) and the PagerSavepoint.pInSavepoint bitvecs of any open
+** savepoints are set. This means if the page is made writable at any
+** point in the future, using a call to sqlite3PagerWrite(), its contents
+** will not be journaled. This saves IO.
+**
+** The acquisition might fail for several reasons.  In all cases,
+** an appropriate error code is returned and *ppPage is set to NULL.
+**
+** See also sqlite3PagerLookup().  Both this routine and Lookup() attempt
+** to find a page in the in-memory cache first.  If the page is not already
+** in memory, this routine goes to disk to read it in whereas Lookup()
+** just returns 0.  This routine acquires a read-lock the first time it
+** has to go to disk, and could also playback an old journal if necessary.
+** Since Lookup() never goes to disk, it never has to deal with locks

+*************************************************************************
+**
+** This file contains the implementation of a write-ahead log (WAL) used in
+** "journal_mode=WAL" mode.
+**
+** WRITE-AHEAD LOG (WAL) FILE FORMAT
+**
+** A WAL file consists of a header followed by zero or more "frames".
+** Each frame records the revised content of a single page from the
+** database file.  All changes to the database are recorded by writing
+** frames into the WAL.  Transactions commit when a frame is written that
+** contains a commit marker.  A single WAL can and usually does record
+** multiple transactions.  Periodically, the content of the WAL is
+** transferred back into the database file in an operation called a
+** "checkpoint".
+**
+** A single WAL file can be used multiple times.  In other words, the
+** WAL can fill up with frames and then be checkpointed and then new
+** frames can overwrite the old ones.  A WAL always grows from beginning
+** toward the end.  Checksums and counters attached to each frame are
+** used to determine which frames within the WAL are valid and which
+** are leftovers from prior checkpoints.
+**
+** The WAL header is 32 bytes in size and consists of the following eight
+** big-endian 32-bit unsigned integer values:
+**
+**     0: Magic number.  0x377f0682 or 0x377f0683
+**     4: File format version.  Currently 3007000
+**     8: Database page size.  Example: 1024
+**    12: Checkpoint sequence number
+**    16: Salt-1, random integer incremented with each checkpoint
+**    20: Salt-2, a different random integer changing with each ckpt
+**    24: Checksum-1 (first part of checksum for first 24 bytes of header).
+**    28: Checksum-2 (second part of checksum for first 24 bytes of header).
+**
+** Immediately following the wal-header are zero or more frames. Each
+** frame consists of a 24-byte frame-header followed by a <page-size> bytes
+** of page data. The frame-header is six big-endian 32-bit unsigned
+** integer values, as follows:
+**
+**     0: Page number.
+**     4: For commit records, the size of the database image in pages
+**        after the commit. For all other records, zero.
+**     8: Salt-1 (copied from the header)
+**    12: Salt-2 (copied from the header)
+**    16: Checksum-1.
+**    20: Checksum-2.
+**
+** A frame is considered valid if and only if the following conditions are
+** true:
+**
+**    (1) The salt-1 and salt-2 values in the frame-header match
+**        salt values in the wal-header
+**
+**    (2) The checksum values in the final 8 bytes of the frame-header
+**        exactly match the checksum computed consecutively on the
+**        WAL header and the first 8 bytes and the content of all frames
+**        up to and including the current frame.
+**
+** The checksum is computed using 32-bit big-endian integers if the
+** magic number in the first 4 bytes of the WAL is 0x377f0683 and it
+** is computed using little-endian if the magic number is 0x377f0682.
+** The checksum values are always stored in the frame header in a
+** big-endian format regardless of which byte order is used to compute
+** the checksum.  The checksum is computed by interpreting the input as
+** an even number of unsigned 32-bit integers: x[0] through x[N].  The
+** algorithm used for the checksum is as follows:
+**
+**   for i from 0 to n-1 step 2:
+**     s0 += x[i] + s1;
+**     s1 += x[i+1] + s0;
+**   endfor
+**
+** Note that s0 and s1 are both weighted checksums using fibonacci weights
+** in reverse order (the largest fibonacci weight occurs on the first element
+** of the sequence being summed.)  The s1 value spans all 32-bit
+** terms of the sequence whereas s0 omits the final term.
+**
+** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the
+** WAL is transferred into the database, then the database is VFS.xSync-ed.
+** The VFS.xSync operations serve as write barriers - all writes launched
+** before the xSync must complete before any write that launches after the
+** xSync begins.
+**
+** After each checkpoint, the salt-1 value is incremented and the salt-2
+** value is randomized.  This prevents old and new frames in the WAL from
+** being considered valid at the same time and being checkpointing together
+** following a crash.
+**
+** READER ALGORITHM
+**
+** To read a page from the database (call it page number P), a reader
+** first checks the WAL to see if it contains page P.  If so, then the
+** last valid instance of page P that is a followed by a commit frame
+** or is a commit frame itself becomes the value read.  If the WAL
+** contains no copies of page P that are valid and which are a commit
+** frame or are followed by a commit frame, then page P is read from
+** the database file.
+**
+** To start a read transaction, the reader records the index of the last
+** valid frame in the WAL.  The reader uses this recorded "mxFrame" value
+** for all subsequent read operations.  New transactions can be appended
+** to the WAL, but as long as the reader uses its original mxFrame value
+** and ignores the newly appended content, it will see a consistent snapshot
+** of the database from a single point in time.  This technique allows
+** multiple concurrent readers to view different versions of the database
+** content simultaneously.
+**
+** The reader algorithm in the previous paragraphs works correctly, but
+** because frames for page P can appear anywhere within the WAL, the
+** reader has to scan the entire WAL looking for page P frames.  If the
+** WAL is large (multiple megabytes is typical) that scan can be slow,
+** and read performance suffers.  To overcome this problem, a separate
+** data structure called the wal-index is maintained to expedite the
+** search for frames of a particular page.
+**
+** WAL-INDEX FORMAT
+**
+** Conceptually, the wal-index is shared memory, though VFS implementations
+** might choose to implement the wal-index using a mmapped file.  Because
+** the wal-index is shared memory, SQLite does not support journal_mode=WAL
+** on a network filesystem.  All users of the database must be able to
+** share memory.
+**
+** In the default unix and windows implementation, the wal-index is a mmapped
+** file whose name is the database name with a "-shm" suffix added.  For that
+** reason, the wal-index is sometimes called the "shm" file.
+**
+** The wal-index is transient.  After a crash, the wal-index can (and should
+** be) reconstructed from the original WAL file.  In fact, the VFS is required
+** to either truncate or zero the header of the wal-index when the last
+** connection to it closes.  Because the wal-index is transient, it can
+** use an architecture-specific format; it does not have to be cross-platform.
+** Hence, unlike the database and WAL file formats which store all values
+** as big endian, the wal-index can store multi-byte values in the native
+** byte order of the host computer.
+**
+** The purpose of the wal-index is to answer this question quickly:  Given
+** a page number P and a maximum frame index M, return the index of the
+** last frame in the wal before frame M for page P in the WAL, or return
+** NULL if there are no frames for page P in the WAL prior to M.
+**
+** The wal-index consists of a header region, followed by an one or
+** more index blocks.
+**
+** The wal-index header contains the total number of frames within the WAL
+** in the mxFrame field.
+**
+** Each index block except for the first contains information on
+** HASHTABLE_NPAGE frames. The first index block contains information on
+** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and
+** HASHTABLE_NPAGE are selected so that together the wal-index header and
+** first index block are the same size as all other index blocks in the
+** wal-index.  The values are:
+**
+**   HASHTABLE_NPAGE      4096
+**   HASHTABLE_NPAGE_ONE  4062
+**
+** Each index block contains two sections, a page-mapping that contains the
+** database page number associated with each wal frame, and a hash-table
+** that allows readers to query an index block for a specific page number.
+** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
+** for the first index block) 32-bit page numbers. The first entry in the
+** first index-block contains the database page number corresponding to the
+** first frame in the WAL file. The first entry in the second index block
+** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
+** the log, and so on.
+**
+** The last index block in a wal-index usually contains less than the full
+** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
+** depending on the contents of the WAL file. This does not change the
+** allocated size of the page-mapping array - the page-mapping array merely
+** contains unused entries.
+**
+** Even without using the hash table, the last frame for page P
+** can be found by scanning the page-mapping sections of each index block
+** starting with the last index block and moving toward the first, and
+** within each index block, starting at the end and moving toward the
+** beginning.  The first entry that equals P corresponds to the frame
+** holding the content for that page.
+**
+** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
+** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
+** hash table for each page number in the mapping section, so the hash
+** table is never more than half full.  The expected number of collisions
+** prior to finding a match is 1.  Each entry of the hash table is an
+** 1-based index of an entry in the mapping section of the same
+** index block.   Let K be the 1-based index of the largest entry in
+** the mapping section.  (For index blocks other than the last, K will
+** always be exactly HASHTABLE_NPAGE (4096) and for the last index block
+** K will be (mxFrame%HASHTABLE_NPAGE).)  Unused slots of the hash table
+** contain a value of 0.
+**
+** To look for page P in the hash table, first compute a hash iKey on
+** P as follows:
+**
+**      iKey = (P * 383) % HASHTABLE_NSLOT
+**
+** Then start scanning entries of the hash table, starting with iKey
+** (wrapping around to the beginning when the end of the hash table is
+** reached) until an unused hash slot is found. Let the first unused slot
+** be at index iUnused.  (iUnused might be less than iKey if there was
+** wrap-around.) Because the hash table is never more than half full,
+** the search is guaranteed to eventually hit an unused entry.  Let
+** iMax be the value between iKey and iUnused, closest to iUnused,
+** where aHash[iMax]==P.  If there is no iMax entry (if there exists
+** no hash slot such that aHash[i]==p) then page P is not in the
+** current index block.  Otherwise the iMax-th mapping entry of the
+** current index block corresponds to the last entry that references
+** page P.
+**
+** A hash search begins with the last index block and moves toward the
+** first index block, looking for entries corresponding to page P.  On
+** average, only two or three slots in each index block need to be
+** examined in order to either find the last entry for page P, or to
+** establish that no such entry exists in the block.  Each index block
+** holds over 4000 entries.  So two or three index blocks are sufficient
+** to cover a typical 10 megabyte WAL file, assuming 1K pages.  8 or 10
+** comparisons (on average) suffice to either locate a frame in the
+** WAL or to establish that the frame does not exist in the WAL.  This
+** is much faster than scanning the entire 10MB WAL.
+**
+** Note that entries are added in order of increasing K.  Hence, one
+** reader might be using some value K0 and a second reader that started
+** at a later time (after additional transactions were added to the WAL
+** and to the wal-index) might be using a different value K1, where K1>K0.
+** Both readers can use the same hash table and mapping section to get
+** the correct result.  There may be entries in the hash table with
+** K>K0 but to the first reader, those entries will appear to be unused
+** slots in the hash table and so the first reader will get an answer as
+** if no values greater than K0 had ever been inserted into the hash table
+** in the first place - which is what reader one wants.  Meanwhile, the
+** second reader using K1 will see additional values that were inserted
+** later, which is exactly what reader two wants.
+**
+** When a rollback occurs, the value of K is decreased. Hash table entries
+** that correspond to frames greater than the new K value are removed
+** from the hash table at this point.

+** A copy of the following object occurs in the wal-index immediately

+** information used by checkpoint.
+**
+** nBackfill is the number of frames in the WAL that have been written
+** back into the database. (We call the act of moving content from WAL to
+** database "backfilling".)  The nBackfill number is never greater than
+** WalIndexHdr.mxFrame.  nBackfill can only be increased by threads
+** holding the WAL_CKPT_LOCK lock (which includes a recovery thread).
+** However, a WAL_WRITE_LOCK thread can move the value of nBackfill from
+** mxFrame back to zero when the WAL is reset.
+**
+** nBackfillAttempted is the largest value of nBackfill that a checkpoint
+** has attempted to achieve.  Normally nBackfill==nBackfillAtempted, however
+** the nBackfillAttempted is set before any backfilling is done and the
+** nBackfill is only set after all backfilling completes.  So if a checkpoint
+** crashes, nBackfillAttempted might be larger than nBackfill.  The
+** WalIndexHdr.mxFrame must never be less than nBackfillAttempted.
+**
+** The aLock[] field is a set of bytes used for locking.  These bytes should
+** never be read or written.
+**
+** There is one entry in aReadMark[] for each reader lock.  If a reader
+** holds read-lock K, then the value in aReadMark[K] is no greater than
+** the mxFrame for that reader.  The value READMARK_NOT_USED (0xffffffff)
+** for any aReadMark[] means that entry is unused.  aReadMark[0] is
+** a special case; its value is never used and it exists as a place-holder
+** to avoid having to offset aReadMark[] indexs by one.  Readers holding
+** WAL_READ_LOCK(0) always ignore the entire WAL and read all content
+** directly from the database.
+**
+** The value of aReadMark[K] may only be changed by a thread that
+** is holding an exclusive lock on WAL_READ_LOCK(K).  Thus, the value of
+** aReadMark[K] cannot changed while there is a reader is using that mark
+** since the reader will be holding a shared lock on WAL_READ_LOCK(K).
+**
+** The checkpointer may only transfer frames from WAL to database where
+** the frame numbers are less than or equal to every aReadMark[] that is
+** in use (that is, every aReadMark[j] for which there is a corresponding
+** WAL_READ_LOCK(j)).  New readers (usually) pick the aReadMark[] with the
+** largest value and will increase an unused aReadMark[] to mxFrame if there
+** is not already an aReadMark[] equal to mxFrame.  The exception to the
+** previous sentence is when nBackfill equals mxFrame (meaning that everything
+** in the WAL has been backfilled into the database) then new readers
+** will choose aReadMark[0] which has value 0 and hence such reader will
+** get all their all content directly from the database file and ignore
+** the WAL.
+**
+** Writers normally append new frames to the end of the WAL.  However,
+** if nBackfill equals mxFrame (meaning that all WAL content has been
+** written back into the database) and if no readers are using the WAL
+** (in other words, if there are no WAL_READ_LOCK(i) where i>0) then
+** the writer will first "reset" the WAL back to the beginning and start
+** writing new content beginning at frame 1.
+**
+** We assume that 32-bit loads are atomic and so no locks are needed in
+** order to read from any aReadMark[] entries.

+**
+*************************************************************************
+** This file implements an external (disk-based) database using BTrees.
+** For a detailed discussion of BTrees, refer to
+**
+**     Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
+**     "Sorting And Searching", pages 473-480. Addison-Wesley
+**     Publishing Company, Reading, Massachusetts.
+**
+** The basic idea is that each page of the file contains N database
+** entries and N+1 pointers to subpages.
+**
+**   ----------------------------------------------------------------
+**   |  Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
+**   ----------------------------------------------------------------
+**
+** All of the keys on the page that Ptr(0) points to have values less
+** than Key(0).  All of the keys on page Ptr(1) and its subpages have
+** values greater than Key(0) and less than Key(1).  All of the keys
+** on Ptr(N) and its subpages have values greater than Key(N-1).  And
+** so forth.
+**
+** Finding a particular key requires reading O(log(M)) pages from the
+** disk where M is the number of entries in the tree.
+**
+** In this implementation, a single file can hold one or more separate
+** BTrees.  Each BTree is identified by the index of its root page.  The
+** key and data for any entry are combined to form the "payload".  A
+** fixed amount of payload can be carried directly on the database
+** page.  If the payload is larger than the preset amount then surplus
+** bytes are stored on overflow pages.  The payload for an entry
+** and the preceding pointer are combined to form a "Cell".  Each
+** page has a small header which contains the Ptr(N) pointer and other
+** information such as the size of key and data.
+**
+** FORMAT DETAILS
+**
+** The file is divided into pages.  The first page is called page 1,
+** the second is page 2, and so forth.  A page number of zero indicates
+** "no such page".  The page size can be any power of 2 between 512 and 65536.
+** Each page can be either a btree page, a freelist page, an overflow
+** page, or a pointer-map page.
+**
+** The first page is always a btree page.  The first 100 bytes of the first
+** page contain a special header (the "file header") that describes the file.
+** The format of the file header is as follows:
+**
+**   OFFSET   SIZE    DESCRIPTION
+**      0      16     Header string: "SQLite format 3\000"

+**
+** The max embedded payload fraction is the amount of the total usable
+** space in a page that can be consumed by a single cell for standard
+** B-tree (non-LEAFDATA) tables.  A value of 255 means 100%.  The default
+** is to limit the maximum cell size so that at least 4 cells will fit
+** on one page.  Thus the default max embedded payload fraction is 64.
+**
+** If the payload for a cell is larger than the max payload, then extra
+** payload is spilled to overflow pages.  Once an overflow page is allocated,
+** as many bytes as possible are moved into the overflow pages without letting
+** the cell size drop below the min embedded payload fraction.
+**
+** The min leaf payload fraction is like the min embedded payload fraction
+** except that it applies to leaf nodes in a LEAFDATA tree.  The maximum
+** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
+** not specified in the header.
+**
+** Each btree pages is divided into three sections:  The header, the
+** cell pointer array, and the cell content area.  Page 1 also has a 100-byte
+** file header that occurs before the page header.
+**
+**      |----------------|
+**      | file header    |   100 bytes.  Page 1 only.
+**      |----------------|
+**      | page header    |   8 bytes for leaves.  12 bytes for interior nodes
+**      |----------------|
+**      | cell pointer   |   |  2 bytes per cell.  Sorted order.
+**      | array          |   |  Grows downward

+**      |----------------|
+**      | unallocated    |

+**      | cell content   |   |  Arbitrary order interspersed with freeblocks.
+**      | area           |   |  and free space fragments.
+**      |----------------|
+**
+** The page headers looks like this:
+**
+**   OFFSET   SIZE     DESCRIPTION
+**      0       1      Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
+**      1       2      byte offset to the first freeblock
+**      3       2      number of cells on this page
+**      5       2      first byte of the cell content area
+**      7       1      number of fragmented free bytes
+**      8       4      Right child (the Ptr(N) value).  Omitted on leaves.
+**
+** The flags define the format of this btree page.  The leaf flag means that
+** this page has no children.  The zerodata flag means that this page carries
+** only keys and no data.  The intkey flag means that the key is an integer
+** which is stored in the key size entry of the cell header rather than in
+** the payload area.
+**
+** The cell pointer array begins on the first byte after the page header.
+** The cell pointer array contains zero or more 2-byte numbers which are
+** offsets from the beginning of the page to the cell content in the cell
+** content area.  The cell pointers occur in sorted order.  The system strives
+** to keep free space after the last cell pointer so that new cells can
+** be easily added without having to defragment the page.
+**
+** Cell content is stored at the very end of the page and grows toward the
+** beginning of the page.
+**
+** Unused space within the cell content area is collected into a linked list of
+** freeblocks.  Each freeblock is at least 4 bytes in size.  The byte offset
+** to the first freeblock is given in the header.  Freeblocks occur in
+** increasing order.  Because a freeblock must be at least 4 bytes in size,
+** any group of 3 or fewer unused bytes in the cell content area cannot
+** exist on the freeblock chain.  A group of 3 or fewer free bytes is called
+** a fragment.  The total number of bytes in all fragments is recorded.
+** in the page header at offset 7.
+**
+**    SIZE    DESCRIPTION
+**      2     Byte offset of the next freeblock
+**      2     Bytes in this freeblock
+**
+** Cells are of variable length.  Cells are stored in the cell content area at
+** the end of the page.  Pointers to the cells are in the cell pointer array
+** that immediately follows the page header.  Cells is not necessarily
+** contiguous or in order, but cell pointers are contiguous and in order.
+**
+** Cell content makes use of variable length integers.  A variable
+** length integer is 1 to 9 bytes where the lower 7 bits of each
+** byte are used.  The integer consists of all bytes that have bit 8 set and
+** the first byte with bit 8 clear.  The most significant byte of the integer
+** appears first.  A variable-length integer may not be more than 9 bytes long.
+** As a special case, all 8 bytes of the 9th byte are used as data.  This
+** allows a 64-bit integer to be encoded in 9 bytes.
+**
+**    0x00                      becomes  0x00000000
+**    0x7f                      becomes  0x0000007f
+**    0x81 0x00                 becomes  0x00000080
+**    0x82 0x00                 becomes  0x00000100
+**    0x80 0x7f                 becomes  0x0000007f
+**    0x8a 0x91 0xd1 0xac 0x78  becomes  0x12345678
+**    0x81 0x81 0x81 0x81 0x01  becomes  0x10204081
+**
+** Variable length integers are used for rowids and to hold the number of
+** bytes of key and data in a btree cell.
+**
+** The content of a cell looks like this:
+**
+**    SIZE    DESCRIPTION
+**      4     Page number of the left child. Omitted if leaf flag is set.
+**     var    Number of bytes of data. Omitted if the zerodata flag is set.
+**     var    Number of bytes of key. Or the key itself if intkey flag is set.
+**      *     Payload
+**      4     First page of the overflow chain.  Omitted if no overflow
+**
+** Overflow pages form a linked list.  Each page except the last is completely
+** filled with data (pagesize - 4 bytes).  The last page can have as little
+** as 1 byte of data.
+**
+**    SIZE    DESCRIPTION
+**      4     Page number of next overflow page
+**      *     Data
+**
+** Freelist pages come in two subtypes: trunk pages and leaf pages.  The
+** file header points to the first in a linked list of trunk page.  Each trunk
+** page points to multiple leaf pages.  The content of a leaf page is
+** unspecified.  A trunk page looks like this:
+**
+**    SIZE    DESCRIPTION
+**      4     Page number of next trunk page

+**   1) When all data is deleted from a page and the page becomes
+**      a free-list leaf page, the page is not written to the database
+**      (as free-list leaf pages contain no meaningful data). Sometimes
+**      such a page is not even journalled (as it will not be modified,
+**      why bother journalling it?).
+**
+**   2) When a free-list leaf page is reused, its content is not read
+**      from the database or written to the journal file (why should it
+**      be, if it is not at all meaningful?).
+**
+** By themselves, these optimizations work fine and provide a handy
+** performance boost to bulk delete or insert operations. However, if
+** a page is moved to the free-list and then reused within the same
+** transaction, a problem comes up. If the page is not journalled when
+** it is moved to the free-list and it is also not journalled when it
+** is extracted from the free-list and reused, then the original data
+** may be lost. In the event of a rollback, it may not be possible
+** to restore the database to its original configuration.
+**
+** The solution is the BtShared.pHasContent bitvec. Whenever a page is
+** moved to become a free-list leaf page, the corresponding bit is
+** set in the bitvec. Whenever a leaf page is extracted from the free-list,

+** A CellArray object contains a cache of pointers and sizes for a
+** consecutive sequence of cells that might be held on multiple pages.
+**
+** The cells in this array are the divider cell or cells from the pParent
+** page plus up to three child pages.  There are a total of nCell cells.
+**
+** pRef is a pointer to one of the pages that contributes cells.  This is
+** used to access information such as MemPage.intKey and MemPage.pBt->pageSize
+** which should be common to all pages that contribute cells to this array.
+**
+** apCell[] and szCell[] hold, respectively, pointers to the start of each
+** cell and the size of each cell.  Some of the apCell[] pointers might refer
+** to overflow cells.  In other words, some apCel[] pointers might not point
+** to content area of the pages.
+**
+** A szCell[] of zero means the size of that cell has not yet been computed.
+**
+** The cells come from as many as four different pages:
+**
+**             -----------
+**             | Parent  |
+**             -----------
+**            /     |     \
+**           /      |      \
+**  ---------   ---------   ---------
+**  |Child-1|   |Child-2|   |Child-3|
+**  ---------   ---------   ---------
+**
+** The order of cells is in the array is for an index btree is:
+**
+**       1.  All cells from Child-1 in order
+**       2.  The first divider cell from Parent
+**       3.  All cells from Child-2 in order
+**       4.  The second divider cell from Parent
+**       5.  All cells from Child-3 in order
+**
+** For a table-btree (with rowids) the items 2 and 4 are empty because
+** content exists only in leaves and there are no divider cells.
+**
+** For an index btree, the apEnd[] array holds pointer to the end of page
+** for Child-1, the Parent, Child-2, the Parent (again), and Child-3,
+** respectively. The ixNx[] array holds the number of cells contained in
+** each of these 5 stages, and all stages to the left.  Hence:
+**
+**    ixNx[0] = Number of cells in Child-1.
+**    ixNx[1] = Number of cells in Child-1 plus 1 for first divider.
+**    ixNx[2] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
+**    ixNx[3] = Number of cells in Child-1 and Child-2 + both divider cells
+**    ixNx[4] = Total number of cells.
+**
+** For a table-btree, the concept is similar, except only apEnd[0]..apEnd[2]
+** are used and they point to the leaf pages only, and the ixNx value are:
+**
+**    ixNx[0] = Number of cells in Child-1.
+**    ixNx[1] = Number of cells in Child-1 and Child-2.
+**    ixNx[2] = Total number of cells.
+**
+** Sometimes when deleting, a child page can have zero cells.  In those
+** cases, ixNx[] entries with higher indexes, and the corresponding apEnd[]
+** entries, shift down.  The end result is that each ixNx[] entry should
+** be larger than the previous

+**       associated with the source database BtShared structure will always

+** 48-bits as required by the IEEE standard.  (This is the

+** the necessary byte swapping is carried out using a 64-bit integer
+** rather than a 64-bit float.  Frank assures us that the code here

+** indentation conventions, each case should be indented by 6 spaces.  But
+** that is a lot of wasted space on the left margin.  So the code within
+** the switch statement will break with convention and be flush-left. Another
+** big comment (similar to this one) will mark the point in the code where
+** we transition back to normal indentation.
+**
+** The formatting of each case is important.  The makefile for SQLite
+** generates two C files "opcodes.h" and "opcodes.c" by scanning this
+** file looking for lines that begin with "case OP_".  The opcodes.h files
+** will be filled with #defines that give unique integer values to each
+** opcode and the opcodes.c file is filled with an array of strings where
+** each string is the symbolic name for the corresponding opcode.  If the
+** case statement is followed by a comment of the form "/# same as ... #/"
+** that comment is used to determine the particular value of the opcode.
+**
+** Other keywords in the comment that follows each case are used to
+** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
+** Keywords include: in1, in2, in3, out2, out3.  See
+** the mkopcodeh.awk script for additional information.
+**
+** Documentation about VDBE opcodes is generated by scanning this file
+** for lines of that contain "Opcode:".  That line and all subsequent
+** comment lines are used in the generation of the opcode.html documentation
+** file.
+**
+** SUMMARY:
+**
+**     Formatting is important to scripts that scan this file.
+**     Do not deviate from the formatting style currently in use.

+** Synopsis: Scan-ahead up to P1 rows
+**
+** This opcode is a prefix opcode to OP_SeekGE.  In other words, this
+** opcode must be immediately followed by OP_SeekGE. This constraint is
+** checked by assert() statements.
+**
+** This opcode uses the P1 through P4 operands of the subsequent
+** OP_SeekGE.  In the text that follows, the operands of the subsequent
+** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4.   Only
+** the P1 and P2 operands of this opcode are also used, and  are called
+** This.P1 and This.P2.
+**
+** This opcode helps to optimize IN operators on a multi-column index
+** where the IN operator is on the later terms of the index by avoiding
+** unnecessary seeks on the btree, substituting steps to the next row
+** of the b-tree instead.  A correct answer is obtained if this opcode
+** is omitted or is a no-op.
+**
+** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which
+** is the desired entry that we want the cursor SeekGE.P1 to be pointing
+** to.  Call this SeekGE.P4/P5 row the "target".
+**
+** If the SeekGE.P1 cursor is not currently pointing to a valid row,
+** then this opcode is a no-op and control passes through into the OP_SeekGE.
+**
+** If the SeekGE.P1 cursor is pointing to a valid row, then that row
+** might be the target row, or it might be near and slightly before the
+** target row.  This opcode attempts to position the cursor on the target
+** row by, perhaps by invoking sqlite3BtreeStep() on the cursor
+** between 0 and This.P1 times.
+**
+** There are three possible outcomes from this opcode:<ol>
+**
+** <li> If after This.P1 steps, the cursor is still pointing to a place that
+**      is earlier in the btree than the target row, then fall through
+**      into the subsquence OP_SeekGE opcode.
+**
+** <li> If the cursor is successfully moved to the target row by 0 or more
+**      sqlite3BtreeNext() calls, then jump to This.P2, which will land just
+**      past the OP_IdxGT or OP_IdxGE opcode that follows the OP_SeekGE.
+**
+** <li> If the cursor ends up past the target row (indicating the the target
+**      row does not exist in the btree) then jump to SeekOP.P2.

+** This file contains code for the VdbeSorter object, used in concert with
+** a VdbeCursor to sort large numbers of keys for CREATE INDEX statements
+** or by SELECT statements with ORDER BY clauses that cannot be satisfied
+** using indexes and without LIMIT clauses.
+**
+** The VdbeSorter object implements a multi-threaded external merge sort
+** algorithm that is efficient even if the number of elements being sorted
+** exceeds the available memory.
+**
+** Here is the (internal, non-API) interface between this module and the
+** rest of the SQLite system:
+**
+**    sqlite3VdbeSorterInit()       Create a new VdbeSorter object.
+**
+**    sqlite3VdbeSorterWrite()      Add a single new row to the VdbeSorter
+**                                  object.  The row is a binary blob in the
+**                                  OP_MakeRecord format that contains both
+**                                  the ORDER BY key columns and result columns
+**                                  in the case of a SELECT w/ ORDER BY, or
+**                                  the complete record for an index entry
+**                                  in the case of a CREATE INDEX.
+**
+**    sqlite3VdbeSorterRewind()     Sort all content previously added.
+**                                  Position the read cursor on the
+**                                  first sorted element.
+**
+**    sqlite3VdbeSorterNext()       Advance the read cursor to the next sorted
+**                                  element.
+**
+**    sqlite3VdbeSorterRowkey()     Return the complete binary blob for the
+**                                  row currently under the read cursor.
+**
+**    sqlite3VdbeSorterCompare()    Compare the binary blob for the row
+**                                  currently under the read cursor against
+**                                  another binary blob X and report if
+**                                  X is strictly less than the read cursor.
+**                                  Used to enforce uniqueness in a
+**                                  CREATE UNIQUE INDEX statement.
+**
+**    sqlite3VdbeSorterClose()      Close the VdbeSorter object and reclaim
+**                                  all resources.
+**
+**    sqlite3VdbeSorterReset()      Refurbish the VdbeSorter for reuse.  This
+**                                  is like Close() followed by Init() only
+**                                  much faster.
+**
+** The interfaces above must be called in a particular order.  Write() can
+** only occur in between Init()/Reset() and Rewind().  Next(), Rowkey(), and
+** Compare() can only occur in between Rewind() and Close()/Reset(). i.e.
+**
+**   Init()
+**   for each record: Write()
+**   Rewind()
+**     Rowkey()/Compare()
+**   Next()
+**   Close()
+**
+** Algorithm:
+**
+** Records passed to the sorter via calls to Write() are initially held
+** unsorted in main memory. Assuming the amount of memory used never exceeds
+** a threshold, when Rewind() is called the set of records is sorted using
+** an in-memory merge sort. In this case, no temporary files are required
+** and subsequent calls to Rowkey(), Next() and Compare() read records
+** directly from main memory.
+**
+** If the amount of space used to store records in main memory exceeds the
+** threshold, then the set of records currently in memory are sorted and
+** written to a temporary file in "Packed Memory Array" (PMA) format.
+** A PMA created at this point is known as a "level-0 PMA". Higher levels
+** of PMAs may be created by merging existing PMAs together - for example
+** merging two or more level-0 PMAs together creates a level-1 PMA.
+**
+** The threshold for the amount of main memory to use before flushing
+** records to a PMA is roughly the same as the limit configured for the
+** page-cache of the main database. Specifically, the threshold is set to
+** the value returned by "PRAGMA main.page_size" multipled by
+** that returned by "PRAGMA main.cache_size", in bytes.
+**
+** If the sorter is running in single-threaded mode, then all PMAs generated
+** are appended to a single temporary file. Or, if the sorter is running in
+** multi-threaded mode then up to (N+1) temporary files may be opened, where
+** N is the configured number of worker threads. In this case, instead of
+** sorting the records and writing the PMA to a temporary file itself, the
+** calling thread usually launches a worker thread to do so. Except, if
+** there are already N worker threads running, the main thread does the work
+** itself.

+** The sorter is running in multi-threaded mode if (a) the library was built
+** with pre-processor symbol SQLITE_MAX_WORKER_THREADS set to a value greater
+** than zero, and (b) worker threads have been enabled at runtime by calling
+** "PRAGMA threads=N" with some value of N greater than 0.
+**
+** When Rewind() is called, any data remaining in memory is flushed to a
+** final PMA. So at this point the data is stored in some number of sorted
+** PMAs within temporary files on disk.
+**
+** If there are fewer than SORTER_MAX_MERGE_COUNT PMAs in total and the
+** sorter is running in single-threaded mode, then these PMAs are merged
+** incrementally as keys are retreived from the sorter by the VDBE.  The
+** MergeEngine object, described in further detail below, performs this
+** merge.
+**
+** Or, if running in multi-threaded mode, then a background thread is
+** launched to merge the existing PMAs. Once the background thread has
+** merged T bytes of data into a single sorted PMA, the main thread
+** begins reading keys from that PMA while the background thread proceeds
+** with merging the next T bytes of data. And so on.
+**
+** Parameter T is set to half the value of the memory threshold used
+** by Write() above to determine when to create a new PMA.
+**
+** If there are more than SORTER_MAX_MERGE_COUNT PMAs in total when
+** Rewind() is called, then a hierarchy of incremental-merges is used.
+** First, T bytes of data from the first SORTER_MAX_MERGE_COUNT PMAs on
+** disk are merged together. Then T bytes of data from the second set, and
+** so on, such that no operation ever merges more than SORTER_MAX_MERGE_COUNT
+** PMAs at a time. This done is to improve locality.
+**
+** If running in multi-threaded mode and there are more than
+** SORTER_MAX_MERGE_COUNT PMAs on disk when Rewind() is called, then more
+** than one background thread may be created. Specifically, there may be
+** one background thread for each temporary file on disk, and one background
+** thread to merge the output of each of the others to a single PMA for
+** the main thread to read from.

+**
+** The aReadr[] array contains a PmaReader object for each of the PMAs being

+**
+** The final (N/2) elements of aTree[] contain the results of comparing
+** pairs of PMA keys together. Element i contains the result of
+** comparing aReadr[2*i-N] and aReadr[2*i-N+1]. Whichever key is smaller, the
+** aTree element is set to the index of it.
+**
+** For the purposes of this comparison, EOF is considered greater than any
+** other key value. If the keys are equal (only possible with two EOF
+** values), it doesn't matter which index is stored.
+**
+** The (N/4) elements of aTree[] that precede the final (N/2) described
+** above contains the index of the smallest of each block of 4 PmaReaders
+** And so on. So that aTree[1] contains the index of the PmaReader that
+** currently points to the smallest key value. aTree[0] is unused.
+**
+** Example:
+**
+**     aReadr[0] -> Banana
+**     aReadr[1] -> Feijoa
+**     aReadr[2] -> Elderberry
+**     aReadr[3] -> Currant
+**     aReadr[4] -> Grapefruit
+**     aReadr[5] -> Apple
+**     aReadr[6] -> Durian
+**     aReadr[7] -> EOF
+**
+**     aTree[] = { X, 5   0, 5    0, 3, 5, 6 }
+**
+** The current element is "Apple" (the value of the key indicated by
+** PmaReader 5). When the Next() operation is invoked, PmaReader 5 will
+** be advanced to the next key in its segment. Say the next key is
+** "Eggplant":
+**
+**     aReadr[5] -> Eggplant
+**
+** The contents of aTree[] are updated first by comparing the new PmaReader
+** 5 key to the current key of PmaReader 4 (still "Grapefruit"). The PmaReader
+** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree.
+** The value of PmaReader 6 - "Durian" - is now smaller than that of PmaReader
+** 5, so aTree[3] is set to 6. Key 0 is smaller than key 6 (Banana<Durian),
+** so the value written into element 1 of the array is 0. As follows:
+**
+**     aTree[] = { X, 0   0, 6    0, 3, 5, 6 }
+**
+** In other words, each time we advance to the next sorter element, log2(N)
+** key comparison operations are required, where N is the number of segments
+** being merged (rounded up to the next power of 2).

+** This routine walks an expression tree and resolves references to
+** table columns and result-set columns.  At the same time, do error
+** checking on function usage and set a flag if any aggregate functions
+** are seen.
+**
+** To resolve table columns references we look for nodes (or subtrees) of the
+** form X.Y.Z or Y.Z or just Z where
+**
+**      X:   The name of a database.  Ex:  "main" or "temp" or
+**           the symbolic name assigned to an ATTACH-ed database.
+**
+**      Y:   The name of a table in a FROM clause.  Or in a trigger
+**           one of the special names "old" or "new".
+**
+**      Z:   The name of a column in table Y.
+**
+** The node at the root of the subtree is modified as follows:
+**
+**    Expr.op        Changed to TK_COLUMN
+**    Expr.pTab      Points to the Table object for X.Y
+**    Expr.iColumn   The column index in X.Y.  -1 for the rowid.
+**    Expr.iTable    The VDBE cursor number for X.Y
+**
+**
+** To resolve result-set references, look for expression nodes of the
+** form Z (with no X and Y prefix) where the Z matches the right-hand
+** size of an AS clause in the result-set of a SELECT.  The Z expression
+** is replaced by a copy of the left-hand side of the result-set expression.
+** Table-name and function resolution occurs on the substituted expression
+** tree.  For example, in:
+**
+**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
+**
+** The "x" term of the order by is replaced by "a+b" to render:
+**
+**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
+**
+** Function calls are checked to make sure that the function is
+** defined and that the correct number of arguments are specified.
+** If the function is an aggregate function, then the NC_HasAgg flag is
+** set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
+** If an expression contains aggregate functions then the EP_Agg
+** property on the expression is set.
+**
+** An error message is left in pParse if anything is amiss.  The number
+** if errors is returned.

+** This function is used by the implementation of the IN (...) operator.
+** The pX parameter is the expression on the RHS of the IN operator, which
+** might be either a list of expressions or a subquery.
+**
+** The job of this routine is to find or create a b-tree object that can
+** be used either to test for membership in the RHS set or to iterate through
+** all members of the RHS set, skipping duplicates.
+**
+** A cursor is opened on the b-tree object that is the RHS of the IN operator
+** and the *piTab parameter is set to the index of that cursor.
+**
+** The returned value of this function indicates the b-tree type, as follows:
+**
+**   IN_INDEX_ROWID      - The cursor was opened on a database table.
+**   IN_INDEX_INDEX_ASC  - The cursor was opened on an ascending index.
+**   IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
+**   IN_INDEX_EPH        - The cursor was opened on a specially created and
+**                         populated epheremal table.
+**   IN_INDEX_NOOP       - No cursor was allocated.  The IN operator must be
+**                         implemented as a sequence of comparisons.
+**
+** An existing b-tree might be used if the RHS expression pX is a simple
+** subquery such as:
+**
+**     SELECT <column1>, <column2>... FROM <table>
+**
+** If the RHS of the IN operator is a list or a more complex subquery, then
+** an ephemeral table might need to be generated from the RHS and then
+** pX->iTable made to point to the ephemeral table instead of an
+** existing table.  In this case, the creation and initialization of the
+** ephmeral table might be put inside of a subroutine, the EP_Subrtn flag
+** will be set on pX and the pX->y.sub fields will be set to show where
+** the subroutine is coded.
+**
+** The inFlags parameter must contain, at a minimum, one of the bits
+** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both.  If inFlags contains
+** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
+** membership test.  When the IN_INDEX_LOOP bit is set, the IN index will
+** be used to loop over all values of the RHS of the IN operator.
+**
+** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
+** through the set members) then the b-tree must not contain duplicates.
+** An epheremal table will be created unless the selected columns are guaranteed
+** to be unique - either because it is an INTEGER PRIMARY KEY or due to
+** a UNIQUE constraint or index.
+**
+** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
+** for fast set membership tests) then an epheremal table must
+** be used unless <columns> is a single INTEGER PRIMARY KEY column or an
+** index can be found with the specified <columns> as its left-most.
+**
+** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
+** if the RHS of the IN operator is a list (not a subquery) then this
+** routine might decide that creating an ephemeral b-tree for membership
+** testing is too expensive and return IN_INDEX_NOOP.  In that case, the
+** calling routine should implement the IN operator using a sequence
+** of Eq or Ne comparison operations.
+**
+** When the b-tree is being used for membership tests, the calling function
+** might need to know whether or not the RHS side of the IN operator
+** contains a NULL.  If prRhsHasNull is not a NULL pointer and
+** if there is any chance that the (...) might contain a NULL value at
+** runtime, then a register is allocated and the register number written
+** to *prRhsHasNull. If there is no chance that the (...) contains a
+** NULL value, then *prRhsHasNull is left unchanged.
+**
+** If a register is allocated and its location stored in *prRhsHasNull, then
+** the value in that register will be NULL if the b-tree contains one or more
+** NULL values, and it will be some non-NULL value if the b-tree contains no
+** NULL values.
+**
+** If the aiMap parameter is not NULL, it must point to an array containing
+** one element for each column returned by the SELECT statement on the RHS
+** of the IN(...) operator. The i'th entry of the array is populated with the
+** offset of the index column that matches the i'th column returned by the
+** SELECT. For example, if the expression and selected index are:
+**
+**   (?,?,?) IN (SELECT a, b, c FROM t1)
+**   CREATE INDEX i1 ON t1(b, c, a);
+**
+** then aiMap[] is populated with {2, 0, 1}.

+*************************************************************************
+** This file contains code associated with the ANALYZE command.
+**
+** The ANALYZE command gather statistics about the content of tables
+** and indices.  These statistics are made available to the query planner
+** to help it make better decisions about how to perform queries.
+**
+** The following system tables are or have been supported:
+**
+**    CREATE TABLE sqlite_stat1(tbl, idx, stat);
+**    CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample);
+**    CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample);
+**    CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample);
+**
+** Additional tables might be added in future releases of SQLite.
+** The sqlite_stat2 table is not created or used unless the SQLite version
+** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled
+** with SQLITE_ENABLE_STAT2.  The sqlite_stat2 table is deprecated.
+** The sqlite_stat2 table is superseded by sqlite_stat3, which is only
+** created and used by SQLite versions 3.7.9 through 3.29.0 when
+** SQLITE_ENABLE_STAT3 defined.  The functionality of sqlite_stat3
+** is a superset of sqlite_stat2 and is also now deprecated.  The
+** sqlite_stat4 is an enhanced version of sqlite_stat3 and is only
+** available when compiled with SQLITE_ENABLE_STAT4 and in SQLite
+** versions 3.8.1 and later.  STAT4 is the only variant that is still
+** supported.
+**
+** For most applications, sqlite_stat1 provides all the statistics required
+** for the query planner to make good choices.
+**
+** Format of sqlite_stat1:
+**
+** There is normally one row per index, with the index identified by the
+** name in the idx column.  The tbl column is the name of the table to
+** which the index belongs.  In each such row, the stat column will be
+** a string consisting of a list of integers.  The first integer in this
+** list is the number of rows in the index.  (This is the same as the
+** number of rows in the table, except for partial indices.)  The second
+** integer is the average number of rows in the index that have the same
+** value in the first column of the index.  The third integer is the average
+** number of rows in the index that have the same value for the first two
+** columns.  The N-th integer (for N>1) is the average number of rows in
+** the index which have the same value for the first N-1 columns.  For
+** a K-column index, there will be K+1 integers in the stat column.  If
+** the index is unique, then the last integer will be 1.
+**
+** The list of integers in the stat column can optionally be followed
+** by the keyword "unordered".  The "unordered" keyword, if it is present,
+** must be separated from the last integer by a single space.  If the
+** "unordered" keyword is present, then the query planner assumes that
+** the index is unordered and will not use the index for a range query.
+**
+** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat
+** column contains a single integer which is the (estimated) number of
+** rows in the table identified by sqlite_stat1.tbl.
+**
+** Format of sqlite_stat2:
+**
+** The sqlite_stat2 is only created and is only used if SQLite is compiled
+** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between
+** 3.6.18 and 3.7.8.  The "stat2" table contains additional information
+** about the distribution of keys within an index.  The index is identified by
+** the "idx" column and the "tbl" column is the name of the table to which
+** the index belongs.  There are usually 10 rows in the sqlite_stat2
+** table for each index.
+**
+** The sqlite_stat2 entries for an index that have sampleno between 0 and 9
+** inclusive are samples of the left-most key value in the index taken at
+** evenly spaced points along the index.  Let the number of samples be S
+** (10 in the standard build) and let C be the number of rows in the index.
+** Then the sampled rows are given by:
+**
+**     rownumber = (i*C*2 + C)/(S*2)
+**
+** For i between 0 and S-1.  Conceptually, the index space is divided into
+** S uniform buckets and the samples are the middle row from each bucket.
+**
+** The format for sqlite_stat2 is recorded here for legacy reference.  This
+** version of SQLite does not support sqlite_stat2.  It neither reads nor
+** writes the sqlite_stat2 table.  This version of SQLite only supports
+** sqlite_stat3.
+**
+** Format for sqlite_stat3:
+**
+** The sqlite_stat3 format is a subset of sqlite_stat4.  Hence, the
+** sqlite_stat4 format will be described first.  Further information
+** about sqlite_stat3 follows the sqlite_stat4 description.
+**
+** Format for sqlite_stat4:
+**
+** As with sqlite_stat2, the sqlite_stat4 table contains histogram data
+** to aid the query planner in choosing good indices based on the values
+** that indexed columns are compared against in the WHERE clauses of
+** queries.
+**
+** The sqlite_stat4 table contains multiple entries for each index.
+** The idx column names the index and the tbl column is the table of the
+** index.  If the idx and tbl columns are the same, then the sample is
+** of the INTEGER PRIMARY KEY.  The sample column is a blob which is the
+** binary encoding of a key from the index.  The nEq column is a
+** list of integers.  The first integer is the approximate number
+** of entries in the index whose left-most column exactly matches
+** the left-most column of the sample.  The second integer in nEq
+** is the approximate number of entries in the index where the
+** first two columns match the first two columns of the sample.
+** And so forth.  nLt is another list of integers that show the approximate
+** number of entries that are strictly less than the sample.  The first
+** integer in nLt contains the number of entries in the index where the
+** left-most column is less than the left-most column of the sample.
+** The K-th integer in the nLt entry is the number of index entries
+** where the first K columns are less than the first K columns of the
+** sample.  The nDLt column is like nLt except that it contains the
+** number of distinct entries in the index that are less than the
+** sample.
+**
+** There can be an arbitrary number of sqlite_stat4 entries per index.
+** The ANALYZE command will typically generate sqlite_stat4 tables
+** that contain between 10 and 40 samples which are distributed across
+** the key space, though not uniformly, and which include samples with
+** large nEq values.
+**
+** Format for sqlite_stat3 redux:
+**
+** The sqlite_stat3 table is like sqlite_stat4 except that it only
+** looks at the left-most column of the index.  The sqlite_stat3.sample
+** column contains the actual value of the left-most column instead
+** of a blob encoding of the complete index key as is found in
+** sqlite_stat4.sample.  The nEq, nLt, and nDLt entries of sqlite_stat3
+** all contain just a single integer which is the same as the first
+** integer in the equivalent columns in sqlite_stat4.

+** values for use by OP_Param opcodes in triggers.  Hence, if the
+** input column is a VIRTUAL table, put it after all the other columns.
+**
+** In the following, N means "normal column", S means STORED, and

+**
+**        CREATE TABLE ex(N,S,V,N,S,V,N,S,V);

+**    OUTPUTS:    0 1 6 2 3 7 4 5 8

+**
+**   3.  The primary key for the row to be deleted must be stored in a
+**       sequence of nPk memory cells starting at iPk.  If nPk==0 that means
+**       that a search record formed from OP_MakeRecord is contained in the

+**   iDataCur already points to the row to delete. If eMode is ONEPASS_OFF
+**   then this function must seek iDataCur to the entry identified by iPk
+**   and nPk before reading from it.
+**
+**   If eMode is ONEPASS_MULTI, then this call is being made as part
+**   of a ONEPASS delete that affects multiple rows. In this case, if
+**   iIdxNoSeek is a valid cursor number (>=0) and is not the same as
+**   iDataCur, then its position should be preserved following the delete
+**   operation. Or, if iIdxNoSeek is not a valid cursor number, the
+**   position of iDataCur should be preserved instead.
+**
+** iIdxNoSeek:
+**   If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,
+**   then it identifies an index cursor (from within array of cursors

+** Deferred and Immediate FKs
+** --------------------------
+**
+** Foreign keys in SQLite come in two flavours: deferred and immediate.
+** If an immediate foreign key constraint is violated,
+** SQLITE_CONSTRAINT_FOREIGNKEY is returned and the current
+** statement transaction rolled back. If a
+** deferred foreign key constraint is violated, no action is taken
+** immediately. However if the application attempts to commit the
+** transaction before fixing the constraint violation, the attempt fails.
+**
+** Deferred constraints are implemented using a simple counter associated
+** with the database handle. The counter is set to zero each time a
+** database transaction is opened. Each time a statement is executed
+** that causes a foreign key violation, the counter is incremented. Each
+** time a statement is executed that removes an existing violation from
+** the database, the counter is decremented. When the transaction is
+** committed, the commit fails if the current value of the counter is
+** greater than zero. This scheme has two big drawbacks:
+**
+**   * When a commit fails due to a deferred foreign key constraint,
+**     there is no way to tell which foreign constraint is not satisfied,
+**     or which row it is not satisfied for.
+**
+**   * If the database contains foreign key violations when the
+**     transaction is opened, this may cause the mechanism to malfunction.
+**
+** Despite these problems, this approach is adopted as it seems simpler
+** than the alternatives.
+**
+** INSERT operations:
+**
+**   I.1) For each FK for which the table is the child table, search
+**        the parent table for a match. If none is found increment the
+**        constraint counter.
+**
+**   I.2) For each FK for which the table is the parent table,
+**        search the child table for rows that correspond to the new
+**        row in the parent table. Decrement the counter for each row
+**        found (as the constraint is now satisfied).
+**
+** DELETE operations:
+**
+**   D.1) For each FK for which the table is the child table,
+**        search the parent table for a row that corresponds to the
+**        deleted row in the child table. If such a row is not found,
+**        decrement the counter.
+**
+**   D.2) For each FK for which the table is the parent table, search
+**        the child table for rows that correspond to the deleted row
+**        in the parent table. For each found increment the counter.
+**
+** UPDATE operations:
+**
+**   An UPDATE command requires that all 4 steps above are taken, but only
+**   for FK constraints for which the affected columns are actually
+**   modified (values must be compared at runtime).
+**
+** Note that I.1 and D.1 are very similar operations, as are I.2 and D.2.
+** This simplifies the implementation a bit.
+**
+** For the purposes of immediate FK constraints, the OR REPLACE conflict
+** resolution is considered to delete rows before the new row is inserted.
+** If a delete caused by OR REPLACE violates an FK constraint, an exception
+** is thrown, even if the FK constraint would be satisfied after the new
+** row is inserted.
+**
+** Immediate constraints are usually handled similarly. The only difference
+** is that the counter used is stored as part of each individual statement
+** object (struct Vdbe). If, after the statement has run, its immediate
+** constraint counter is greater than zero,
+** it returns SQLITE_CONSTRAINT_FOREIGNKEY
+** and the statement transaction is rolled back. An exception is an INSERT
+** statement that inserts a single row only (no triggers). In this case,
+** instead of using a counter, an exception is thrown immediately if the
+** INSERT violates a foreign key constraint. This is necessary as such
+** an INSERT does not open a statement transaction.
+**
+** TODO: How should dropping a table be handled? How should renaming a
+** table be handled?
+**
+**
+** Query API Notes
+** ---------------
+**
+** Before coding an UPDATE or DELETE row operation, the code-generator
+** for those two operations needs to know whether or not the operation
+** requires any FK processing and, if so, which columns of the original
+** row are required by the FK processing VDBE code (i.e. if FKs were
+** implemented using triggers, which of the old.* columns would be
+** accessed). No information is required by the code-generator before
+** coding an INSERT operation. The functions used by the UPDATE/DELETE
+** generation code to query for this information are:
+**
+**   sqlite3FkRequired() - Test to see if FK processing is required.
+**   sqlite3FkOldmask()  - Query for the set of required old.* columns.
+**
+**
+** Externally accessible module functions
+** --------------------------------------
+**
+**   sqlite3FkCheck()    - Check for foreign key violations.
+**   sqlite3FkActions()  - Code triggers for ON UPDATE/ON DELETE actions.
+**   sqlite3FkDelete()   - Delete an FKey structure.
+*/
+
+/*
+** VDBE Calling Convention
+** -----------------------
+**
+** Example:
+**
+**   For the following INSERT statement:
+**
+**     CREATE TABLE t1(a, b INTEGER PRIMARY KEY, c);
+**     INSERT INTO t1 VALUES(1, 2, 3.1);
+**
+**   Register (x):        2    (type integer)
+**   Register (x+1):      1    (type integer)
+**   Register (x+2):      NULL (type NULL)
+**   Register (x+3):      3.1  (type real)
+*/
+
+/*
+** A foreign key constraint requires that the key columns in the parent
+** table are collectively subject to a UNIQUE or PRIMARY KEY constraint.
+** Given that pParent is the parent table for foreign key constraint pFKey,
+** search the schema for a unique index on the parent key columns.
+**
+** If successful, zero is returned. If the parent key is an INTEGER PRIMARY
+** KEY column, then output variable *ppIdx is set to NULL. Otherwise, *ppIdx
+** is set to point to the unique index.
+**
+** If the parent key consists of a single column (the foreign key constraint
+** is not a composite foreign key), output variable *paiCol is set to NULL.
+** Otherwise, it is set to point to an allocated array of size N, where
+** N is the number of columns in the parent key. The first element of the
+** array is the index of the child table column that is mapped by the FK
+** constraint to the parent table column stored in the left-most column
+** of index *ppIdx. The second element of the array is the index of the
+** child table column that corresponds to the second left-most column of
+** *ppIdx, and so on.
+**
+** If the required index cannot be found, either because:
+**
+**   1) The named parent key columns do not exist, or
+**
+**   2) The named parent key columns do exist, but are not subject to a
+**      UNIQUE or PRIMARY KEY constraint, or
+**
+**   3) No parent key columns were provided explicitly as part of the
+**      foreign key definition, and the parent table does not have a
+**      PRIMARY KEY, or
+**
+**   4) No parent key columns were provided explicitly as part of the
+**      foreign key definition, and the PRIMARY KEY of the parent table
+**      consists of a different number of columns to the child key in
+**      the child table.
+**
+** then non-zero is returned, and a "foreign key mismatch" error loaded
+** into pParse. If an OOM error occurs, non-zero is returned and the
+** pParse->db->mallocFailed flag is set.

+**    insert into TABLE (IDLIST) default values
+**
+** The IDLIST following the table name is always optional.  If omitted,
+** then a list of all (non-hidden) columns for the table is substituted.
+** The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
+** is omitted.
+**
+** For the pSelect parameter holds the values to be inserted for the
+** first two forms shown above.  A VALUES clause is really just short-hand
+** for a SELECT statement that omits the FROM clause and everything else
+** that follows.  If the pSelect parameter is NULL, that means that the
+** DEFAULT VALUES form of the INSERT statement is intended.
+**
+** The code generated follows one of four templates.  For a simple
+** insert with data coming from a single-row VALUES clause, the code executes
+** once straight down through.  Pseudo-code follows (we call this
+** the "1st template"):
+**
+**         open write cursor to <table> and its indices
+**         put VALUES clause expressions into registers
+**         write the resulting record into <table>
+**         cleanup
+**
+** The three remaining templates assume the statement is of the form
+**
+**   INSERT INTO <table> SELECT ...
+**
+** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
+** in other words if the SELECT pulls all columns from a single table
+** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
+** if <table2> and <table1> are distinct tables but have identical
+** schemas, including all the same indices, then a special optimization
+** is invoked that copies raw records from <table2> over to <table1>.
+** See the xferOptimization() function for the implementation of this
+** template.  This is the 2nd template.
+**
+**         open a write cursor to <table>
+**         open read cursor on <table2>
+**         transfer all records in <table2> over to <table>
+**         close cursors
+**         foreach index on <table>
+**           open a write cursor on the <table> index
+**           open a read cursor on the corresponding <table2> index
+**           transfer all records from the read to the write cursors
+**           close cursors
+**         end foreach
+**
+** The 3rd template is for when the second template does not apply
+** and the SELECT clause does not read from <table> at any time.
+** The generated code follows this template:
+**
+**         X <- A
+**         goto B
+**      A: setup for the SELECT
+**         loop over the rows in the SELECT
+**           load values into registers R..R+n
+**           yield X
+**         end loop
+**         cleanup after the SELECT
+**         end-coroutine X
+**      B: open write cursor to <table> and its indices
+**      C: yield X, at EOF goto D
+**         insert the select result into <table> from R..R+n
+**         goto C
+**      D: cleanup
+**
+** The 4th template is used if the insert statement takes its
+** values from a SELECT but the data is being inserted into a table
+** that is also read as part of the SELECT.  In the third form,
+** we have to use an intermediate table to store the results of
+** the select.  The template is like this:
+**
+**         X <- A
+**         goto B
+**      A: setup for the SELECT
+**         loop over the tables in the SELECT
+**           load value into register R..R+n
+**           yield X
+**         end loop
+**         cleanup after the SELECT
+**         end co-routine R
+**      B: open temp table
+**      L: yield X, at EOF goto M
+**         insert row from R..R+n into temp table
+**         goto L
+**      M: open write cursor to <table> and its indices
+**         rewind temp table
+**      C: loop over rows of intermediate table
+**           transfer values form intermediate table into <table>
+**         end loop

+** Generate code to do constraint checks prior to an INSERT or an UPDATE
+** on table pTab.
+**
+** The regNewData parameter is the first register in a range that contains
+** the data to be inserted or the data after the update.  There will be
+** pTab->nCol+1 registers in this range.  The first register (the one
+** that regNewData points to) will contain the new rowid, or NULL in the
+** case of a WITHOUT ROWID table.  The second register in the range will
+** contain the content of the first table column.  The third register will
+** contain the content of the second table column.  And so forth.
+**
+** The regOldData parameter is similar to regNewData except that it contains
+** the data prior to an UPDATE rather than afterwards.  regOldData is zero
+** for an INSERT.  This routine can distinguish between UPDATE and INSERT by
+** checking regOldData for zero.
+**
+** For an UPDATE, the pkChng boolean is true if the true primary key (the
+** rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
+** might be modified by the UPDATE.  If pkChng is false, then the key of
+** the iDataCur content table is guaranteed to be unchanged by the UPDATE.
+**
+** For an INSERT, the pkChng boolean indicates whether or not the rowid
+** was explicitly specified as part of the INSERT statement.  If pkChng
+** is zero, it means that the either rowid is computed automatically or
+** that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
+** pkChng will only be true if the INSERT statement provides an integer
+** value for either the rowid column or its INTEGER PRIMARY KEY alias.
+**
+** The code generated by this routine will store new index entries into
+** registers identified by aRegIdx[].  No index entry is created for
+** indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
+** the same as the order of indices on the linked list of indices
+** at pTab->pIndex.
+**
+** (2019-05-07) The generated code also creates a new record for the
+** main table, if pTab is a rowid table, and stores that record in the
+** register identified by aRegIdx[nIdx] - in other words in the first
+** entry of aRegIdx[] past the last index.  It is important that the
+** record be generated during constraint checks to avoid affinity changes
+** to the register content that occur after constraint checks but before
+** the new record is inserted.
+**
+** The caller must have already opened writeable cursors on the main
+** table and all applicable indices (that is to say, all indices for which
+** aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
+** inserting or updating a rowid table, or the cursor for the PRIMARY KEY
+** index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor
+** for the first index in the pTab->pIndex list.  Cursors for other indices
+** are at iIdxCur+N for the N-th element of the pTab->pIndex list.
+**
+** This routine also generates code to check constraints.  NOT NULL,
+** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
+** then the appropriate action is performed.  There are five possible
+** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
+**
+**  Constraint type  Action       What Happens
+**  ---------------  ----------   ----------------------------------------
+**  any              ROLLBACK     The current transaction is rolled back and
+**                                sqlite3_step() returns immediately with a
+**                                return code of SQLITE_CONSTRAINT.
+**
+**  any              ABORT        Back out changes from the current command
+**                                only (do not do a complete rollback) then
+**                                cause sqlite3_step() to return immediately
+**                                with SQLITE_CONSTRAINT.
+**
+**  any              FAIL         Sqlite3_step() returns immediately with a
+**                                return code of SQLITE_CONSTRAINT.  The
+**                                transaction is not rolled back and any
+**                                changes to prior rows are retained.
+**
+**  any              IGNORE       The attempt in insert or update the current
+**                                row is skipped, without throwing an error.
+**                                Processing continues with the next row.
+**                                (There is an immediate jump to ignoreDest.)
+**
+**  NOT NULL         REPLACE      The NULL value is replace by the default
+**                                value for that column.  If the default value
+**                                is NULL, the action is the same as ABORT.
+**
+**  UNIQUE           REPLACE      The other row that conflicts with the row
+**                                being inserted is removed.
+**
+**  CHECK            REPLACE      Illegal.  The results in an exception.
+**
+** Which action to take is determined by the overrideError parameter.
+** Or if overrideError==OE_Default, then the pParse->onError parameter
+** is used.  Or if pParse->onError==OE_Default then the onError value
+** for the constraint is used.

+**     In this case rows are being delivered sorted order. The ephermal
+**     table is not required. Instead, the current set of values
+**     is compared against previous row. If they match, the new row
+**     is not distinct and control jumps to VM address addrRepeat. Otherwise,
+**     the VM program proceeds with processing the new row.
+**

+**     in an array of registers used to store the previous result row so that
+**     it can be compared to the next. The caller must ensure that this
+**     register is initialized to NULL.  (The fixDistinctOpenEph() routine
+**     will take care of this initialization.)
+**
+**   WHERE_DISTINCT_UNIQUE:
+**     In this case it has already been determined that the rows are distinct.
+**     No special action is required. The return value is zero.
+**
+** Parameter pEList is the list of expressions used to generated the

+** of recursive-query, marked with the SrcList->a[].fg.isRecursive flag.
+**
+** The setup-query runs once to generate an initial set of rows that go
+** into a Queue table.  Rows are extracted from the Queue table one by
+** one.  Each row extracted from Queue is output to pDest.  Then the single
+** extracted row (now in the iCurrent table) becomes the content of the
+** recursive-table for a recursive-query run.  The output of the recursive-query
+** is added back into the Queue table.  Then another row is extracted from Queue
+** and the iteration continues until the Queue table is empty.
+**
+** If the compound query operator is UNION then no duplicate rows are ever
+** inserted into the Queue table.  The iDistinct table keeps a copy of all rows
+** that have ever been inserted into Queue and causes duplicates to be
+** discarded.  If the operator is UNION ALL, then duplicates are allowed.
+**
+** If the query has an ORDER BY, then entries in the Queue table are kept in
+** ORDER BY order and the first entry is extracted for each cycle.  Without
+** an ORDER BY, the Queue table is just a FIFO.
+**
+** If a LIMIT clause is provided, then the iteration stops after LIMIT rows
+** have been output to pDest.  A LIMIT of zero means to output no rows and a
+** negative LIMIT means to output all rows.  If there is also an OFFSET clause
+** with a positive value, then the first OFFSET outputs are discarded rather
+** than being sent to pDest.  The LIMIT count does not begin until after OFFSET
+** rows have been skipped.

+**
+** We assume a query of the following form:
+**
+**      <selectA>  <operator>  <selectB>  ORDER BY <orderbylist>
+**
+** <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT.  The idea
+** is to code both <selectA> and <selectB> with the ORDER BY clause as
+** co-routines.  Then run the co-routines in parallel and merge the results
+** into the output.  In addition to the two coroutines (called selectA and
+** selectB) there are 7 subroutines:
+**
+**    outA:    Move the output of the selectA coroutine into the output
+**             of the compound query.
+**
+**    outB:    Move the output of the selectB coroutine into the output
+**             of the compound query.  (Only generated for UNION and
+**             UNION ALL.  EXCEPT and INSERTSECT never output a row that
+**             appears only in B.)
+**
+**    AltB:    Called when there is data from both coroutines and A<B.
+**
+**    AeqB:    Called when there is data from both coroutines and A==B.
+**
+**    AgtB:    Called when there is data from both coroutines and A>B.
+**
+**    EofA:    Called when data is exhausted from selectA.
+**
+**    EofB:    Called when data is exhausted from selectB.
+**
+** The implementation of the latter five subroutines depend on which
+** <operator> is used:
+**
+**
+**             UNION ALL         UNION            EXCEPT          INTERSECT
+**          -------------  -----------------  --------------  -----------------
+**   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
+**
+**   AeqB:   outA, nextA         nextA             nextA         outA, nextA
+**
+**   AgtB:   outB, nextB      outB, nextB          nextB            nextB
+**
+**   EofA:   outB, nextB      outB, nextB          halt             halt
+**
+**   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
+**
+** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
+** causes an immediate jump to EofA and an EOF on B following nextB causes
+** an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
+** following nextX causes a jump to the end of the select processing.
+**
+** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
+** within the output subroutine.  The regPrev register set holds the previously
+** output value.  A comparison is made against this value and the output
+** is skipped if the next results would be the same as the previous.
+**
+** The implementation plan is to implement the two coroutines and seven
+** subroutines first, then put the control logic at the bottom.  Like this:
+**
+**          goto Init
+**     coA: coroutine for left query (A)
+**     coB: coroutine for right query (B)
+**    outA: output one row of A
+**    outB: output one row of B (UNION and UNION ALL only)
+**    EofA: ...
+**    EofB: ...
+**    AltB: ...
+**    AeqB: ...
+**    AgtB: ...
+**    Init: initialize coroutine registers
+**          yield coA
+**          if eof(A) goto EofA
+**          yield coB
+**          if eof(B) goto EofB
+**    Cmpr: Compare A, B
+**          Jump AltB, AeqB, AgtB
+**     End: ...
+**
+** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
+** actually called using Gosub and they do not Return.  EofA and EofB loop
+** until all data is exhausted then jump to the "end" labe.  AltB, AeqB,
+** and AgtB jump to either L2 or to one of EofA or EofB.

+**
+** Suppose the original expression integer constant.  Even though the table
+** has the nullRow flag set, because the expression is an integer constant,
+** it will not be NULLed out.  So instead, we insert an OP_IfNullRow opcode
+** that checks to see if the nullRow flag is set on the table.  If the nullRow
+** flag is set, then the value in the register is set to NULL and the original
+** expression is bypassed.  If the nullRow flag is not set, then the original
+** expression runs to populate the register.
+**
+** Example where this is needed:
+**
+**      CREATE TABLE t1(a INTEGER PRIMARY KEY, b INT);
+**      CREATE TABLE t2(x INT UNIQUE);
+**
+**      SELECT a,b,m,x FROM t1 LEFT JOIN (SELECT 59 AS m,x FROM t2) ON b=x;
+**
+** When the subquery on the right side of the LEFT JOIN is flattened, we
+** have to add OP_IfNullRow in front of the OP_Integer that implements the
+** "m" value of the subquery so that a NULL will be loaded instead of 59
+** when processing a non-matched row of the left.

+** This routine attempts to flatten subqueries as a performance optimization.
+** This routine returns 1 if it makes changes and 0 if no flattening occurs.
+**
+** To understand the concept of flattening, consider the following
+** query:
+**
+**     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
+**
+** The default way of implementing this query is to execute the
+** subquery first and store the results in a temporary table, then
+** run the outer query on that temporary table.  This requires two
+** passes over the data.  Furthermore, because the temporary table
+** has no indices, the WHERE clause on the outer query cannot be
+** optimized.
+**
+** This routine attempts to rewrite queries such as the above into
+** a single flat select, like this:
+**
+**     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
+**
+** The code generated for this simplification gives the same result
+** but only has to scan the data once.  And because indices might
+** exist on the table t1, a complete scan of the data might be
+** avoided.
+**
+** Flattening is subject to the following constraints:
+**
+**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
+**        The subquery and the outer query cannot both be aggregates.
+**
+**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
+**        (2) If the subquery is an aggregate then
+**        (2a) the outer query must not be a join and
+**        (2b) the outer query must not use subqueries
+**             other than the one FROM-clause subquery that is a candidate
+**             for flattening.  (This is due to ticket [2f7170d73bf9abf80]
+**             from 2015-02-09.)
+**
+**   (3)  If the subquery is the right operand of a LEFT JOIN then
+**        (3a) the subquery may not be a join and
+**        (3b) the FROM clause of the subquery may not contain a virtual
+**             table and
+**        (3c) the outer query may not be an aggregate.
+**        (3d) the outer query may not be DISTINCT.
+**        See also (26) for restrictions on RIGHT JOIN.
+**
+**   (4)  The subquery can not be DISTINCT.
+**
+**  (**)  At one point restrictions (4) and (5) defined a subset of DISTINCT
+**        sub-queries that were excluded from this optimization. Restriction
+**        (4) has since been expanded to exclude all DISTINCT subqueries.
+**
+**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
+**        If the subquery is aggregate, the outer query may not be DISTINCT.
+**
+**   (7)  The subquery must have a FROM clause.  TODO:  For subqueries without
+**        A FROM clause, consider adding a FROM clause with the special
+**        table sqlite_once that consists of a single row containing a
+**        single NULL.
+**
+**   (8)  If the subquery uses LIMIT then the outer query may not be a join.
+**
+**   (9)  If the subquery uses LIMIT then the outer query may not be aggregate.
+**
+**  (**)  Restriction (10) was removed from the code on 2005-02-05 but we
+**        accidently carried the comment forward until 2014-09-15.  Original
+**        constraint: "If the subquery is aggregate then the outer query
+**        may not use LIMIT."
+**
+**  (11)  The subquery and the outer query may not both have ORDER BY clauses.
+**
+**  (**)  Not implemented.  Subsumed into restriction (3).  Was previously
+**        a separate restriction deriving from ticket #350.
+**
+**  (13)  The subquery and outer query may not both use LIMIT.
+**
+**  (14)  The subquery may not use OFFSET.
+**
+**  (15)  If the outer query is part of a compound select, then the
+**        subquery may not use LIMIT.
+**        (See ticket #2339 and ticket [02a8e81d44]).
+**
+**  (16)  If the outer query is aggregate, then the subquery may not
+**        use ORDER BY.  (Ticket #2942)  This used to not matter
+**        until we introduced the group_concat() function.
+**
+**  (17)  If the subquery is a compound select, then
+**        (17a) all compound operators must be a UNION ALL, and
+**        (17b) no terms within the subquery compound may be aggregate
+**              or DISTINCT, and
+**        (17c) every term within the subquery compound must have a FROM clause
+**        (17d) the outer query may not be
+**              (17d1) aggregate, or
+**              (17d2) DISTINCT
+**        (17e) the subquery may not contain window functions, and
+**        (17f) the subquery must not be the RHS of a LEFT JOIN.
+**        (17g) either the subquery is the first element of the outer
+**              query or there are no RIGHT or FULL JOINs in any arm
+**              of the subquery.  (This is a duplicate of condition (27b).)
+**
+**        The parent and sub-query may contain WHERE clauses. Subject to
+**        rules (11), (13) and (14), they may also contain ORDER BY,
+**        LIMIT and OFFSET clauses.  The subquery cannot use any compound
+**        operator other than UNION ALL because all the other compound
+**        operators have an implied DISTINCT which is disallowed by
+**        restriction (4).
+**
+**        Also, each component of the sub-query must return the same number
+**        of result columns. This is actually a requirement for any compound
+**        SELECT statement, but all the code here does is make sure that no
+**        such (illegal) sub-query is flattened. The caller will detect the
+**        syntax error and return a detailed message.
+**
+**  (18)  If the sub-query is a compound select, then all terms of the
+**        ORDER BY clause of the parent must be copies of a term returned
+**        by the parent query.
+**
+**  (19)  If the subquery uses LIMIT then the outer query may not
+**        have a WHERE clause.
+**
+**  (20)  If the sub-query is a compound select, then it must not use
+**        an ORDER BY clause.  Ticket #3773.  We could relax this constraint
+**        somewhat by saying that the terms of the ORDER BY clause must
+**        appear as unmodified result columns in the outer query.  But we
+**        have other optimizations in mind to deal with that case.
+**
+**  (21)  If the subquery uses LIMIT then the outer query may not be
+**        DISTINCT.  (See ticket [752e1646fc]).
+**
+**  (22)  The subquery may not be a recursive CTE.
+**
+**  (23)  If the outer query is a recursive CTE, then the sub-query may not be
+**        a compound query.  This restriction is because transforming the
+**        parent to a compound query confuses the code that handles
+**        recursive queries in multiSelect().
+**
+**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
+**        The subquery may not be an aggregate that uses the built-in min() or
+**        or max() functions.  (Without this restriction, a query like:
+**        "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily
+**        return the value X for which Y was maximal.)
+**
+**  (25)  If either the subquery or the parent query contains a window
+**        function in the select list or ORDER BY clause, flattening
+**        is not attempted.
+**
+**  (26)  The subquery may not be the right operand of a RIGHT JOIN.
+**        See also (3) for restrictions on LEFT JOIN.
+**
+**  (27)  The subquery may not contain a FULL or RIGHT JOIN unless it
+**        is the first element of the parent query.  This must be the
+**        the case if:
+**        (27a) the subquery is not compound query, and
+**        (27b) the subquery is a compound query and the RIGHT JOIN occurs
+**              in any arm of the compound query.  (See also (17g).)
+**
+**  (28)  The subquery is not a MATERIALIZED CTE.
+**
+**  (29)  Either the subquery is not the right-hand operand of a join with an
+**        ON or USING clause nor the right-hand operand of a NATURAL JOIN, or
+**        the right-most table within the FROM clause of the subquery
+**        is not part of an outer join.
+**
+**
+** In this routine, the "p" parameter is a pointer to the outer query.
+** The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
+** uses aggregates.
+**
+** If flattening is not attempted, this routine is a no-op and returns 0.
+** If flattening is attempted this routine returns 1.
+**
+** All of the expression analysis must occur on both the outer query and
+** the subquery before this routine runs.

+** The WHERE-clause constant propagation optimization.

+** If the WHERE clause contains terms of the form COLUMN=CONSTANT or
+** CONSTANT=COLUMN that are top-level AND-connected terms that are not
+** part of a ON clause from a LEFT JOIN, then throughout the query
+** replace all other occurrences of COLUMN with CONSTANT.
+**
+** For example, the query:
+**
+**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
+**
+** Is transformed into
+**
+**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=39 AND t3.c=39
+**
+** Return true if any transformations where made and false if not.
+**
+** Implementation note:  Constant propagation is tricky due to affinity
+** and collating sequence interactions.  Consider this example:
+**
+**    CREATE TABLE t1(a INT,b TEXT);
+**    INSERT INTO t1 VALUES(123,'0123');
+**    SELECT * FROM t1 WHERE a=123 AND b=a;
+**    SELECT * FROM t1 WHERE a=123 AND b=123;
+**
+** The two SELECT statements above should return different answers.  b=a
+** is alway true because the comparison uses numeric affinity, but b=123
+** is false because it uses text affinity and '0123' is not the same as '123'.
+** To work around this, the expression tree is not actually changed from
+** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
+** and the "123" value is hung off of the pLeft pointer.  Code generator
+** routines know to generate the constant "123" instead of looking up the
+** column value.  Also, to avoid collation problems, this optimization is
+** only attempted if the "a=123" term uses the default BINARY collation.
+**
+** 2021-05-25 forum post 6a06202608: Another troublesome case is...
+**
+**    CREATE TABLE t1(x);
+**    INSERT INTO t1 VALUES(10.0);
+**    SELECT 1 FROM t1 WHERE x=10 AND x LIKE 10;
+**
+** The query should return no rows, because the t1.x value is '10.0' not '10'
+** and '10.0' is not LIKE '10'.  But if we are not careful, the first WHERE
+** term "x=10" will cause the second WHERE term to become "10 LIKE 10",
+** resulting in a false positive.  To avoid this, constant propagation for
+** columns with BLOB affinity is only allowed if the constant is used with
+** operators ==, <=, <, >=, >, or IS in a way that will cause the correct
+** type conversions to occur.  See logic associated with the bHasAffBlob flag

+**           it is allowed by putting the extra terms on the HAVING clause.
+**           The added HAVING clause is pointless if the subquery lacks
+**           a GROUP BY clause.  But such a HAVING clause is also harmless
+**           so there does not appear to be any reason to add extra logic
+**           to suppress it. **)
+**
+**   (2) The inner query is the recursive part of a common table expression.
+**
+**   (3) The inner query has a LIMIT clause (since the changes to the WHERE
+**       clause would change the meaning of the LIMIT).
+**
+**   (4) The inner query is the right operand of a LEFT JOIN and the
+**       expression to be pushed down does not come from the ON clause
+**       on that LEFT JOIN.
+**
+**   (5) The WHERE clause expression originates in the ON or USING clause
+**       of a LEFT JOIN where iCursor is not the right-hand table of that
+**       left join.  An example:
+**
+**           SELECT *
+**           FROM (SELECT 1 AS a1 UNION ALL SELECT 2) AS aa
+**           JOIN (SELECT 1 AS b2 UNION ALL SELECT 2) AS bb ON (a1=b2)
+**           LEFT JOIN (SELECT 8 AS c3 UNION ALL SELECT 9) AS cc ON (b2=2);
+**
+**       The correct answer is three rows:  (1,1,NULL),(2,2,8),(2,2,9).
+**       But if the (b2=2) term were to be pushed down into the bb subquery,
+**       then the (1,1,NULL) row would be suppressed.
+**
+**   (6) Window functions make things tricky as changes to the WHERE clause
+**       of the inner query could change the window over which window
+**       functions are calculated. Therefore, do not attempt the optimization
+**       if:
+**
+**     (6a) The inner query uses multiple incompatible window partitions.
+**
+**     (6b) The inner query is a compound and uses window-functions.
+**
+**     (6c) The WHERE clause does not consist entirely of constants and
+**          copies of expressions found in the PARTITION BY clause of
+**          all window-functions used by the sub-query. It is safe to
+**          filter out entire partitions, as this does not change the
+**          window over which any window-function is calculated.
+**
+**   (7) The inner query is a Common Table Expression (CTE) that should
+**       be materialized.  (This restriction is implemented in the calling
+**       routine.)
+**
+** Return 0 if no changes are made and non-zero if one or more WHERE clause

+** The VACUUM command is used to clean up the database,

+**
+**   (1)  Create a new transient database file
+**   (2)  Copy all content from the database being vacuumed into
+**        the new transient database file
+**   (3)  Copy content from the transient database back into the
+**        original database.
+**
+** The transient database requires temporary disk space approximately
+** equal to the size of the original database.  The copy operation of
+** step (3) requires additional temporary disk space approximately equal
+** to the size of the original database for the rollback journal.
+** Hence, temporary disk space that is approximately 2x the size of the
+** original database is required.  Every page of the database is written
+** approximately 3 times:  Once for step (2) and twice for step (3).
+** Two writes per page are required in step (3) because the original
+** database content must be written into the rollback journal prior to
+** overwriting the database with the vacuumed content.
+**
+** Only 1x temporary space and only 1x writes would be required if
+** the copy of step (3) were replaced by deleting the original database
+** and renaming the transient database as the original.  But that will
+** not work if other processes are attached to the original database.
+** And a power loss in between deleting the original and renaming the
+** transient would cause the database file to appear to be deleted

+** clause subexpression is separated from the others by AND operators,
+** usually, or sometimes subexpressions separated by OR.
+**
+** All WhereTerms are collected into a single WhereClause structure.
+** The following identity holds:
+**
+**        WhereTerm.pWC->a[WhereTerm.idx] == WhereTerm
+**
+** When a term is of the form:
+**
+**              X <op> <expr>
+**
+** where X is a column name and <op> is one of certain operators,
+** then WhereTerm.leftCursor and WhereTerm.u.leftColumn record the
+** cursor number and column number for X.  WhereTerm.eOperator records
+** the <op> using a bitmask encoding defined by WO_xxx below.  The
+** use of a bitmask encoding for the operator allows us to search
+** quickly for terms that match any of several different operators.
+**
+** A WhereTerm might also be two or more subterms connected by OR:
+**
+**         (t1.X <op> <expr>) OR (t1.Y <op> <expr>) OR ....
+**
+** In this second case, wtFlag has the TERM_ORINFO bit set and eOperator==WO_OR
+** and the WhereTerm.u.pOrInfo field points to auxiliary information that
+** is collected about the OR clause.
+**
+** If a term in the WHERE clause does not match either of the two previous
+** categories, then eOperator==0.  The WhereTerm.pExpr field is still set
+** to the original subexpression content and wtFlags is set up appropriately
+** but no other fields in the WhereTerm object are meaningful.
+**
+** When eOperator!=0, prereqRight and prereqAll record sets of cursor numbers,
+** but they do so indirectly.  A single WhereMaskSet structure translates
+** cursor number into bits and the translated bit is stored in the prereq
+** fields.  The translation is used in order to maximize the number of
+** bits that will fit in a Bitmask.  The VDBE cursor numbers might be
+** spread out over the non-negative integers.  For example, the cursor
+** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45.  The WhereMaskSet
+** translates these sparse cursor numbers into consecutive integers
+** beginning with 0 in order to make the best possible use of the available
+** bits in the Bitmask.  So, in the example above, the cursor numbers
+** would be mapped into integers 0 through 7.
+**
+** The number of terms in a join is limited by the number of bits
+** in prereqRight and prereqAll.  The default is 64 bits, hence SQLite
+** is only able to process joins with 64 or fewer tables.

+** Disable a term in the WHERE clause.  Except, do not disable the term

+**
+** Consider the term t2.z='ok' in the following queries:
+**
+**   (1)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x WHERE t2.z='ok'
+**   (2)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x AND t2.z='ok'
+**   (3)  SELECT * FROM t1, t2 WHERE t1.a=t2.x AND t2.z='ok'
+**
+** The t2.z='ok' is disabled in the in (2) because it originates
+** in the ON clause.  The term is disabled in (3) because it is not part
+** of a LEFT OUTER JOIN.  In (1), the term is not disabled.
+**
+** Disabling a term causes that term to not be tested in the inner loop
+** of the join.  Disabling is an optimization.  When terms are satisfied
+** by indices, we disable them to prevent redundant tests in the inner
+** loop.  We would get the correct results if nothing were ever disabled,
+** but joins might run a little slower.  The trick is to disable as much
+** as we can without disabling too much.  If we disabled in (1), we'd get
+** the wrong answer.  See ticket #813.
+**
+** If all the children of a term are disabled, then that term is also
+** automatically disabled.  In this way, terms get disabled if derived

+** Suppose the WHERE clause is this:  a==5 AND b IN (1,2,3) AND c>5 AND c<10
+** The index has as many as three equality constraints, but in this
+** example, the third "c" value is an inequality.  So only two

+** a==5 and b IN (1,2,3).  The current values for a and b will be stored
+** in consecutive registers and the index of the first register is returned.
+**
+** In the example above nEq==2.  But this subroutine works for any value
+** of nEq including 0.  If nEq==0, this routine is nearly a no-op.
+** The only thing it does is allocate the pLevel->iMem memory cell and
+** compute the affinity string.
+**
+** The nExtraReg parameter is 0 or 1.  It is 0 if all WHERE clause constraints
+** are == or IN and are covered by the nEq.  nExtraReg is 1 if there is
+** an inequality constraint (such as the "c>=5 AND c<10" in the example) that
+** occurs after the nEq quality constraints.
+**
+** This routine allocates a range of nEq+nExtraReg memory cells and returns
+** the index of the first memory cell in that range. The code that
+** calls this routine will use that memory range to store keys for

+**                          ^^^^^^^^^^^^^^^^^^^^
+**
+** This routine analyzes terms such as the middle term in the above example.
+** A WhereOrTerm object is computed and attached to the term under
+** analysis, regardless of the outcome of the analysis.  Hence:
+**
+**     WhereTerm.wtFlags   |=  TERM_ORINFO
+**     WhereTerm.u.pOrInfo  =  a dynamically allocated WhereOrTerm object
+**
+** The term being analyzed must have two or more of OR-connected subterms.
+** A single subterm might be a set of AND-connected sub-subterms.
+** Examples of terms under analysis:
+**
+**     (A)     t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
+**     (B)     x=expr1 OR expr2=x OR x=expr3
+**     (C)     t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
+**     (D)     x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
+**     (E)     (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
+**     (F)     x>A OR (x=A AND y>=B)
+**
+** CASE 1:
+**
+** If all subterms are of the form T.C=expr for some single column of C and
+** a single table T (as shown in example B above) then create a new virtual
+** term that is an equivalent IN expression.  In other words, if the term
+** being analyzed is:
+**
+**      x = expr1  OR  expr2 = x  OR  x = expr3
+**
+** then create a new virtual term like this:
+**
+**      x IN (expr1,expr2,expr3)
+**
+** CASE 2:
+**
+** If there are exactly two disjuncts and one side has x>A and the other side
+** has x=A (for the same x and A) then add a new virtual conjunct term to the
+** WHERE clause of the form "x>=A".  Example:
+**
+**      x>A OR (x=A AND y>B)    adds:    x>=A
+**
+** The added conjunct can sometimes be helpful in query planning.
+**
+** CASE 3:
+**
+** If all subterms are indexable by a single table T, then set
+**
+**     WhereTerm.eOperator              =  WO_OR
+**     WhereTerm.u.pOrInfo->indexable  |=  the cursor number for table T
+**
+** A subterm is "indexable" if it is of the form
+** "T.C <op> <expr>" where C is any column of table T and
+** <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
+** A subterm is also indexable if it is an AND of two or more
+** subsubterms at least one of which is indexable.  Indexable AND
+** subterms have their eOperator set to WO_AND and they have
+** u.pAndInfo set to a dynamically allocated WhereAndTerm object.
+**
+** From another point of view, "indexable" means that the subterm could
+** potentially be used with an index if an appropriate index exists.
+** This analysis does not consider whether or not the index exists; that
+** is decided elsewhere.  This analysis only looks at whether subterms
+** appropriate for indexing exist.
+**
+** All examples A through E above satisfy case 3.  But if a term
+** also satisfies case 1 (such as B) we know that the optimizer will
+** always prefer case 1, so in that case we pretend that case 3 is not
+** satisfied.
+**
+** It might be the case that multiple tables are indexable.  For example,
+** (E) above is indexable on tables P, Q, and R.
+**
+** Terms that satisfy case 3 are candidates for lookup by using
+** separate indices to find rowids for each subterm and composing
+** the union of all rowids using a RowSet object.  This is similar
+** to "bitmap indices" in other database engines.
+**
+** OTHERWISE:
+**
+** If none of cases 1, 2, or 3 apply, then leave the eOperator set to
+** zero.  This term is not useful for search.

+**     cost = nRow * 3.0                    // full-table scan
+**     cost = nRow * K                      // scan of covering index
+**     cost = nRow * (K+3.0)                // scan of non-covering index
+**
+** where K is a value between 1.1 and 3.0 set based on the relative
+** estimated average size of the index and table records.
+**
+** For an index scan, where nVisit is the number of index rows visited
+** by the scan, and nSeek is the number of seek operations required on
+** the index b-tree:
+**
+**     cost = nSeek * (log(nRow) + K * nVisit)          // covering index
+**     cost = nSeek * (log(nRow) + (K+3.0) * nVisit)    // non-covering index
+**
+** Normally, nSeek is 1. nSeek values greater than 1 come about if the
+** WHERE clause includes "x IN (....)" terms used in place of "x=?". Or when
+** implicit "x IN (SELECT x FROM tbl)" terms are added for skip-scans.
+**
+** The estimated values (nRow, nVisit, nSeek) often contain a large amount
+** of uncertainty.  For this reason, scoring is designed to pick plans that
+** "do the least harm" if the estimates are inaccurate.  For example, a
+** log(nRow) factor is omitted from a non-covering index scan in order to
+** bias the scoring in favor of using an index, since the worst-case
+** performance of using an index is far better than the worst-case performance
+** of a full table scan.

+** Generate the beginning of the loop used for WHERE clause processing.
+** The return value is a pointer to an opaque structure that contains
+** information needed to terminate the loop.  Later, the calling routine
+** should invoke sqlite3WhereEnd() with the return value of this function
+** in order to complete the WHERE clause processing.
+**
+** If an error occurs, this routine returns NULL.
+**
+** The basic idea is to do a nested loop, one loop for each table in
+** the FROM clause of a select.  (INSERT and UPDATE statements are the
+** same as a SELECT with only a single table in the FROM clause.)  For
+** example, if the SQL is this:
+**
+**       SELECT * FROM t1, t2, t3 WHERE ...;
+**
+** Then the code generated is conceptually like the following:
+**
+**      foreach row1 in t1 do       \    Code generated
+**        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
+**          foreach row3 in t3 do   /
+**            ...
+**          end                     \    Code generated
+**        end                        |-- by sqlite3WhereEnd()
+**      end                         /
+**
+** Note that the loops might not be nested in the order in which they
+** appear in the FROM clause if a different order is better able to make
+** use of indices.  Note also that when the IN operator appears in
+** the WHERE clause, it might result in additional nested loops for
+** scanning through all values on the right-hand side of the IN.
+**
+** There are Btree cursors associated with each table.  t1 uses cursor
+** number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
+** And so forth.  This routine generates code to open those VDBE cursors
+** and sqlite3WhereEnd() generates the code to close them.
+**
+** The code that sqlite3WhereBegin() generates leaves the cursors named
+** in pTabList pointing at their appropriate entries.  The [...] code
+** can use OP_Column and OP_Rowid opcodes on these cursors to extract
+** data from the various tables of the loop.
+**
+** If the WHERE clause is empty, the foreach loops must each scan their
+** entire tables.  Thus a three-way join is an O(N^3) operation.  But if
+** the tables have indices and there are terms in the WHERE clause that
+** refer to those indices, a complete table scan can be avoided and the
+** code will run much faster.  Most of the work of this routine is checking
+** to see if there are indices that can be used to speed up the loop.
+**
+** Terms of the WHERE clause are also used to limit which rows actually
+** make it to the "..." in the middle of the loop.  After each "foreach",
+** terms of the WHERE clause that use only terms in that loop and outer
+** loops are evaluated and if false a jump is made around all subsequent
+** inner loops (or around the "..." if the test occurs within the inner-
+** most loop)
+**
+** OUTER JOINS
+**
+** An outer join of tables t1 and t2 is conceptally coded as follows:
+**
+**    foreach row1 in t1 do
+**      flag = 0
+**      foreach row2 in t2 do
+**        start:
+**          ...
+**          flag = 1
+**      end
+**      if flag==0 then
+**        move the row2 cursor to a null row
+**        goto start
+**      fi
+**    end
+**
+** ORDER BY CLAUSE PROCESSING
+**
+** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
+** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
+** if there is one.  If there is no ORDER BY clause or if this routine
+** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
+**
+** The iIdxCur parameter is the cursor number of an index.  If
+** WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
+** to use for OR clause processing.  The WHERE clause should use this
+** specific cursor.  If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
+** the first cursor in an array of cursors for all indices.  iIdxCur should
+** be used to compute the appropriate cursor depending on which index is
+** used.

+** SELECT REWRITING
+**
+**   Any SELECT statement that contains one or more window functions in
+**   either the select list or ORDER BY clause (the only two places window
+**   functions may be used) is transformed by function sqlite3WindowRewrite()
+**   in order to support window function processing. For example, with the
+**   schema:
+**
+**     CREATE TABLE t1(a, b, c, d, e, f, g);
+**
+**   the statement:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
+**
+**   is transformed to:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   The flattening optimization is disabled when processing this transformed
+**   SELECT statement. This allows the implementation of the window function
+**   (in this case max()) to process rows sorted in order of (c, d), which
+**   makes things easier for obvious reasons. More generally:
+**
+**     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to
+**       the sub-query.
+**
+**     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
+**
+**     * Terminals from each of the expression trees that make up the
+**       select-list and ORDER BY expressions in the parent query are
+**       selected by the sub-query. For the purposes of the transformation,
+**       terminals are column references and aggregate functions.
+**
+**   If there is more than one window function in the SELECT that uses
+**   the same window declaration (the OVER bit), then a single scan may
+**   be used to process more than one window function. For example:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
+**            min(e) OVER (PARTITION BY c ORDER BY d)
+**     FROM t1;
+**
+**   is transformed in the same way as the example above. However:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
+**            min(e) OVER (PARTITION BY a ORDER BY b)
+**     FROM t1;
+**
+**   Must be transformed to:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
+**           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
+**         ) ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   so that both min() and max() may process rows in the order defined by
+**   their respective window declarations.
+**
+** INTERFACE WITH SELECT.C
+**
+**   When processing the rewritten SELECT statement, code in select.c calls
+**   sqlite3WhereBegin() to begin iterating through the results of the
+**   sub-query, which is always implemented as a co-routine. It then calls
+**   sqlite3WindowCodeStep() to process rows and finish the scan by calling
+**   sqlite3WhereEnd().
+**
+**   sqlite3WindowCodeStep() generates VM code so that, for each row returned
+**   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
+**   When the sub-routine is invoked:
+**
+**     * The results of all window-functions for the row are stored
+**       in the associated Window.regResult registers.
+**
+**     * The required terminal values are stored in the current row of
+**       temp table Window.iEphCsr.
+**
+**   In some cases, depending on the window frame and the specific window
+**   functions invoked, sqlite3WindowCodeStep() caches each entire partition
+**   in a temp table before returning any rows. In other cases it does not.
+**   This detail is encapsulated within this file, the code generated by
+**   select.c is the same in either case.
+**
+** BUILT-IN WINDOW FUNCTIONS
+**
+**   This implementation features the following built-in window functions:
+**
+**     row_number()
+**     rank()
+**     dense_rank()
+**     percent_rank()
+**     cume_dist()
+**     ntile(N)
+**     lead(expr [, offset [, default]])
+**     lag(expr [, offset [, default]])
+**     first_value(expr)
+**     last_value(expr)
+**     nth_value(expr, N)
+**
+**   These are the same built-in window functions supported by Postgres.
+**   Although the behaviour of aggregate window functions (functions that
+**   can be used as either aggregates or window funtions) allows them to
+**   be implemented using an API, built-in window functions are much more
+**   esoteric. Additionally, some window functions (e.g. nth_value())
+**   may only be implemented by caching the entire partition in memory.
+**   As such, some built-in window functions use the same API as aggregate
+**   window functions and some are implemented directly using VDBE
+**   instructions. Additionally, for those functions that use the API, the
+**   window frame is sometimes modified before the SELECT statement is
+**   rewritten. For example, regardless of the specified window frame, the
+**   row_number() function always uses:
+**
+**     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+**
+**   See sqlite3WindowUpdate() for details.
+**
+**   As well as some of the built-in window functions, aggregate window
+**   functions min() and max() are implemented using VDBE instructions if
+**   the start of the window frame is declared as anything other than
+**   UNBOUNDED PRECEDING.

+**   in the WindowCodeArg.pMWin list.
+**

+**   variable indicates when rows may be removed from the temp table (in
+**   order to reduce memory requirements - it would always be safe just
+**   to leave them there). Possible values for eDelete are:
+**
+**      WINDOW_RETURN_ROW:
+**        An input row can be discarded after it is returned to the caller.
+**
+**      WINDOW_AGGINVERSE:
+**        An input row can be discarded after the window functions xInverse()
+**        callbacks have been invoked in it.

+**        An input row can be discarded after the window functions xStep()
+**        callbacks have been invoked in it.
+**
+** start,current,end
+**   Consider a window-frame similar to the following:
+**
+**     (ORDER BY a, b GROUPS BETWEEN 2 PRECEDING AND 2 FOLLOWING)
+**
+**   The windows functions implmentation caches the input rows in a temp
+**   table, sorted by "a, b" (it actually populates the cache lazily, and
+**   aggressively removes rows once they are no longer required, but that's
+**   a mere detail). It keeps three cursors open on the temp table. One
+**   (current) that points to the next row to return to the query engine
+**   once its window function values have been calculated. Another (end)
+**   points to the next row to call the xStep() method of each window function
+**   on (so that it is 2 groups ahead of current). And a third (start) that
+**   points to the next row to call the xInverse() method of each window
+**   function on.
+**
+**   Each cursor (start, current and end) consists of a VDBE cursor
+**   (WindowCsrAndReg.csr) and an array of registers (starting at
+**   WindowCodeArg.reg) that always contains a copy of the peer values
+**   read from the corresponding cursor.
+**

+**     }
+**     while( !eof csrCurrent ){
+**       RETURN_ROW
+**     }
+**
+** For the most part, the patterns above are adapted to support UNBOUNDED by
+** assuming that it is equivalent to "infinity PRECEDING/FOLLOWING" and
+** CURRENT ROW by assuming that it is equivilent to "0 PRECEDING/FOLLOWING".
+** This is optimized of course - branches that will never be taken and
+** conditions that are always true are omitted from the VM code. The only
+** exceptional case is:
+**
+**   ROWS BETWEEN <expr1> FOLLOWING AND UNBOUNDED FOLLOWING
+**
+**     ... loop started by sqlite3WhereBegin() ...
+**     if( new partition ){
+**       Gosub flush
+**     }
+**     Insert new row into eph table.
+**     if( first row of partition ){
+**       Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+**       regStart = <expr1>
+**     }else{
+**       AGGSTEP
+**     }
+**   }
+**   flush:
+**     AGGSTEP
+**     while( 1 ){
+**       if( (regStart--)<=0 ){
+**         AGGINVERSE
+**         if( eof ) break
+**       }
+**       RETURN_ROW
+**     }
+**     while( !eof csrCurrent ){
+**       RETURN_ROW
+**     }
+**
+** Also requiring special handling are the cases:
+**
+**   ROWS BETWEEN <expr1> PRECEDING AND <expr2> PRECEDING
+**   ROWS BETWEEN <expr1> FOLLOWING AND <expr2> FOLLOWING
+**
+** when (expr1 < expr2). This is detected at runtime, not by this function.
+** To handle this case, the pseudo-code programs depicted above are modified
+** slightly to be:
+**
+**     ... loop started by sqlite3WhereBegin() ...
+**     if( new partition ){
+**       Gosub flush
+**     }
+**     Insert new row into eph table.
+**     if( first row of partition ){
+**       Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+**       regEnd = <expr2>
+**       regStart = <expr1>
+**       if( regEnd < regStart ){
+**         RETURN_ROW
+**         delete eph table contents
+**         continue
+**       }
+**     ...
+**
+** The new "continue" statement in the above jumps to the next iteration
+** of the outer loop - the one started by sqlite3WhereBegin().
+**
+** The various GROUPS cases are implemented using the same patterns as
+** ROWS. The VM code is modified slightly so that:
+**
+**   1. The else branch in the main loop is only taken if the row just
+**      added to the ephemeral table is the start of a new group. In
+**      other words, it becomes:
+**
+**         ... loop started by sqlite3WhereBegin() ...
+**         if( new partition ){
+**           Gosub flush
+**         }
+**         Insert new row into eph table.
+**         if( first row of partition ){
+**           Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+**           regEnd = <expr2>
+**           regStart = <expr1>
+**         }else if( new group ){
+**           ...
+**         }
+**       }
+**
+**   2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
+**      AGGINVERSE step processes the current row of the relevant cursor and
+**      all subsequent rows belonging to the same group.
+**
+** RANGE window frames are a little different again. As for GROUPS, the
+** main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
+** deal in groups instead of rows. As for ROWS and GROUPS, there are three
+** basic cases:
+**
+**   RANGE BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
+**
+**     ... loop started by sqlite3WhereBegin() ...
+**       if( new partition ){
+**         Gosub flush
+**       }
+**       Insert new row into eph table.
+**       if( first row of partition ){
+**         Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+**         regEnd = <expr2>
+**         regStart = <expr1>
+**       }else{
+**         AGGSTEP
+**         while( (csrCurrent.key + regEnd) < csrEnd.key ){
+**           RETURN_ROW
+**           while( csrStart.key + regStart) < csrCurrent.key ){
+**             AGGINVERSE
+**           }
+**         }
+**       }
+**     }
+**     flush:
+**       AGGSTEP
+**       while( 1 ){
+**         RETURN ROW
+**         if( csrCurrent is EOF ) break;
+**           while( csrStart.key + regStart) < csrCurrent.key ){
+**             AGGINVERSE
+**           }
+**         }
+**       }
+**
+** In the above notation, "csr.key" means the current value of the ORDER BY
+** expression (there is only ever 1 for a RANGE that uses an <expr> FOLLOWING
+** or <expr PRECEDING) read from cursor csr.

+** various aspects of the generated parser.
+**    YYCODETYPE         is the data type used to store the integer codes
+**                       that represent terminal and non-terminal symbols.
+**                       "unsigned char" is used if there are fewer than
+**                       256 symbols.  Larger types otherwise.
+**    YYNOCODE           is a number of type YYCODETYPE that is not used for
+**                       any terminal or nonterminal symbol.
+**    YYFALLBACK         If defined, this indicates that one or more tokens
+**                       (also known as: "terminal symbols") have fall-back
+**                       values which should be used if the original symbol
+**                       would not parse.  This permits keywords to sometimes
+**                       be used as identifiers, for example.
+**    YYACTIONTYPE       is the data type used for "action codes" - numbers
+**                       that indicate what to do in response to the next
+**                       token.
+**    sqlite3ParserTOKENTYPE     is the data type used for minor type for terminal
+**                       symbols.  Background: A "minor type" is a semantic
+**                       value associated with a terminal or non-terminal
+**                       symbols.  For example, for an "ID" terminal symbol,
+**                       the minor type might be the name of the identifier.
+**                       Each non-terminal can have a different minor type.
+**                       Terminal symbols all have the same minor type, though.
+**                       This macros defines the minor type for terminal
+**                       symbols.
+**    YYMINORTYPE        is the data type used for all minor types.
+**                       This is typically a union of many types, one of
+**                       which is sqlite3ParserTOKENTYPE.  The entry in the union
+**                       for terminal symbols is called "yy0".
+**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
+**                       zero the stack is dynamically sized using realloc()
+**    sqlite3ParserARG_SDECL     A static variable declaration for the %extra_argument
+**    sqlite3ParserARG_PDECL     A parameter declaration for the %extra_argument
+**    sqlite3ParserARG_PARAM     Code to pass %extra_argument as a subroutine parameter
+**    sqlite3ParserARG_STORE     Code to store %extra_argument into yypParser
+**    sqlite3ParserARG_FETCH     Code to extract %extra_argument from yypParser
+**    sqlite3ParserCTX_*         As sqlite3ParserARG_ except for %extra_context
+**    YYERRORSYMBOL      is the code number of the error symbol.  If not
+**                       defined, then do no error processing.
+**    YYNSTATE           the combined number of states.
+**    YYNRULE            the number of rules in the grammar
+**    YYNTOKEN           Number of terminal symbols
+**    YY_MAX_SHIFT       Maximum value for shift actions
+**    YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
+**    YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
+**    YY_ERROR_ACTION    The yy_action[] code for syntax error
+**    YY_ACCEPT_ACTION   The yy_action[] code for accept
+**    YY_NO_ACTION       The yy_action[] code for no-op
+**    YY_MIN_REDUCE      Minimum value for reduce actions
+**    YY_MAX_REDUCE      Maximum value for reduce actions

+/* Next are the tables used to determine what action to take based on the
+** current state and lookahead token.  These tables are used to implement
+** functions that take a state number and lookahead value and return an
+** action integer.
+**
+** Suppose the action integer is N.  Then the action is determined as
+** follows
+**
+**   0 <= N <= YY_MAX_SHIFT             Shift N.  That is, push the lookahead
+**                                      token onto the stack and goto state N.
+**
+**   N between YY_MIN_SHIFTREDUCE       Shift to an arbitrary state then
+**     and YY_MAX_SHIFTREDUCE           reduce by rule N-YY_MIN_SHIFTREDUCE.
+**
+**   N == YY_ERROR_ACTION               A syntax error has occurred.
+**
+**   N == YY_ACCEPT_ACTION              The parser accepts its input.
+**
+**   N == YY_NO_ACTION                  No such action.  Denotes unused
+**                                      slots in the yy_action[] table.
+**
+**   N between YY_MIN_REDUCE            Reduce by rule N-YY_MIN_REDUCE
+**     and YY_MAX_REDUCE
+**
+** The action table is constructed as a single large table named yy_action[].
+** Given state S and lookahead X, the action is computed as either:
+**
+**    (A)   N = yy_action[ yy_shift_ofst[S] + X ]
+**    (B)   N = yy_default[S]
+**
+** The (A) formula is preferred.  The B formula is used instead if
+** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
+**
+** The formulas above are for computing the action when the lookahead is
+** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
+** a reduce action) then the yy_reduce_ofst[] array is used in place of
+** the yy_shift_ofst[] array.
+**
+** The following are the tables generated in this section:
+**
+**  yy_action[]        A single table containing all actions.
+**  yy_lookahead[]     A table containing the lookahead for each entry in
+**                     yy_action.  Used to detect hash collisions.
+**  yy_shift_ofst[]    For each state, the offset into yy_action for
+**                     shifting terminals.
+**  yy_reduce_ofst[]   For each state, the offset into yy_action for
+**                     shifting non-terminals after a reduce.
+**  yy_default[]       Default action for each state.

+**
+**   (1) START     At the beginning or end of an SQL statement.  This routine

+**                 in any other state.

+**   (2) NORMAL    We are in the middle of statement which ends with a single
+**                 semicolon.
+**
+**   (3) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of
+**                 a statement.
+**
+**   (4) CREATE    The keyword CREATE has been seen at the beginning of a
+**                 statement, possibly preceded by EXPLAIN and/or followed by
+**                 TEMP or TEMPORARY
+**
+**   (5) TRIGGER   We are in the middle of a trigger definition that must be
+**                 ended by a semicolon, the keyword END, and another semicolon.
+**
+**   (6) SEMI      We've seen the first semicolon in the ";END;" that occurs at
+**                 the end of a trigger definition.
+**
+**   (7) END       We've seen the ";END" of the ";END;" that occurs at the end
+**                 of a trigger definition.
+**
+** Transitions between states above are determined by tokens extracted
+** from the input.  The following tokens are significant:
+**
+**   (0) tkSEMI      A semicolon.
+**   (1) tkWS        Whitespace.
+**   (2) tkOTHER     Any other SQL token.
+**   (3) tkEXPLAIN   The "explain" keyword.
+**   (4) tkCREATE    The "create" keyword.
+**   (5) tkTEMP      The "temp" or "temporary" keyword.
+**   (6) tkTRIGGER   The "trigger" keyword.
+**   (7) tkEND       The "end" keyword.
+**
+** Whitespace never causes a state transition and is always ignored.
+** This means that a SQL string of all whitespace is invalid.
+**
+** If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
+** to recognize the end of a trigger can be omitted.  All we have to do

+** This function is used to parse both URIs and non-URI filenames passed by the

+** URIs specified as part of ATTACH statements.
+**
+** The first argument to this function is the name of the VFS to use (or
+** a NULL to signify the default VFS) if the URI does not contain a "vfs=xxx"
+** query parameter. The second argument contains the URI (or non-URI filename)
+** itself. When this function is called the *pFlags variable should contain
+** the default flags to open the database handle with. The value stored in
+** *pFlags may be updated before returning if the URI filename contains
+** "cache=xxx" or "mode=xxx" query parameters.
+**
+** If successful, SQLITE_OK is returned. In this case *ppVfs is set to point to
+** the VFS that should be used to open the database file. *pzFile is set to
+** point to a buffer containing the name of the file to open.  The value
+** stored in *pzFile is a database name acceptable to sqlite3_uri_parameter()
+** and is in the same format as names created using sqlite3_create_filename().
+** The caller must invoke sqlite3_free_filename() (not sqlite3_free()!) on
+** the value returned in *pzFile to avoid a memory leak.
+**
+** If an error occurs, then an SQLite error code is returned and *pzErrMsg
+** may be set to point to a buffer containing an English language error
+** message. It is the responsibility of the caller to eventually release
+** this buffer by calling sqlite3_free().

+**

+**       (in which case SQLITE_CORE is not defined), or

+**       SQLite (in which case SQLITE_ENABLE_FTS3 is defined).
+*/
+
+/* The full-text index is stored in a series of b+tree (-like)
+** structures called segments which map terms to doclists.  The
+** structures are like b+trees in layout, but are constructed from the
+** bottom up in optimal fashion and are not updatable.  Since trees
+** are built from the bottom up, things will be described from the
+** bottom up.
+**
+**
+**** Varints ****
+** The basic unit of encoding is a variable-length integer called a
+** varint.  We encode variable-length integers in little-endian order
+** using seven bits * per byte as follows:
+**
+** KEY:
+**         A = 0xxxxxxx    7 bits of data and one flag bit
+**         B = 1xxxxxxx    7 bits of data and one flag bit
+**
+**  7 bits - A
+** 14 bits - BA
+** 21 bits - BBA
+** and so on.
+**
+** This is similar in concept to how sqlite encodes "varints" but
+** the encoding is not the same.  SQLite varints are big-endian
+** are are limited to 9 bytes in length whereas FTS3 varints are
+** little-endian and can be up to 10 bytes in length (in theory).
+**
+** Example encodings:
+**
+**     1:    0x01
+**   127:    0x7f
+**   128:    0x81 0x00
+**
+**
+**** Document lists ****
+** A doclist (document list) holds a docid-sorted list of hits for a
+** given term.  Doclists hold docids and associated token positions.
+** A docid is the unique integer identifier for a single document.
+** A position is the index of a word within the document.  The first
+** word of the document has a position of 0.
+**
+** FTS3 used to optionally store character offsets using a compile-time
+** option.  But that functionality is no longer supported.
+**
+** A doclist is stored like this:
+**
+** array {
+**   varint docid;          (delta from previous doclist)
+**   array {                (position list for column 0)
+**     varint position;     (2 more than the delta from previous position)
+**   }
+**   array {
+**     varint POS_COLUMN;   (marks start of position list for new column)
+**     varint column;       (index of new column)
+**     array {
+**       varint position;   (2 more than the delta from previous position)
+**     }
+**   }
+**   varint POS_END;        (marks end of positions for this document.
+** }
+**
+** Here, array { X } means zero or more occurrences of X, adjacent in
+** memory.  A "position" is an index of a token in the token stream
+** generated by the tokenizer. Note that POS_END and POS_COLUMN occur
+** in the same logical place as the position element, and act as sentinals
+** ending a position list array.  POS_END is 0.  POS_COLUMN is 1.
+** The positions numbers are not stored literally but rather as two more
+** than the difference from the prior position, or the just the position plus
+** 2 for the first position.  Example:
+**
+**   label:       A B C D E  F  G H   I  J K
+**   value:     123 5 9 1 1 14 35 0 234 72 0
+**
+** The 123 value is the first docid.  For column zero in this document
+** there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
+** at D signals the start of a new column; the 1 at E indicates that the
+** new column is column number 1.  There are two positions at 12 and 45
+** (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
+** 234 at I is the delta to next docid (357).  It has one position 70
+** (72-2) and then terminates with the 0 at K.
+**
+** A "position-list" is the list of positions for multiple columns for
+** a single docid.  A "column-list" is the set of positions for a single
+** column.  Hence, a position-list consists of one or more column-lists,
+** a document record consists of a docid followed by a position-list and
+** a doclist consists of one or more document records.
+**
+** A bare doclist omits the position information, becoming an
+** array of varint-encoded docids.
+**
+**** Segment leaf nodes ****
+** Segment leaf nodes store terms and doclists, ordered by term.  Leaf
+** nodes are written using LeafWriter, and read using LeafReader (to
+** iterate through a single leaf node's data) and LeavesReader (to
+** iterate through a segment's entire leaf layer).  Leaf nodes have
+** the format:
+**
+** varint iHeight;             (height from leaf level, always 0)
+** varint nTerm;               (length of first term)
+** char pTerm[nTerm];          (content of first term)
+** varint nDoclist;            (length of term's associated doclist)
+** char pDoclist[nDoclist];    (content of doclist)
+** array {
+**                             (further terms are delta-encoded)
+**   varint nPrefix;           (length of prefix shared with previous term)
+**   varint nSuffix;           (length of unshared suffix)
+**   char pTermSuffix[nSuffix];(unshared suffix of next term)
+**   varint nDoclist;          (length of term's associated doclist)
+**   char pDoclist[nDoclist];  (content of doclist)
+** }
+**
+** Here, array { X } means zero or more occurrences of X, adjacent in
+** memory.
+**
+** Leaf nodes are broken into blocks which are stored contiguously in
+** the %_segments table in sorted order.  This means that when the end
+** of a node is reached, the next term is in the node with the next
+** greater node id.
+**
+** New data is spilled to a new leaf node when the current node
+** exceeds LEAF_MAX bytes (default 2048).  New data which itself is
+** larger than STANDALONE_MIN (default 1024) is placed in a standalone
+** node (a leaf node with a single term and doclist).  The goal of
+** these settings is to pack together groups of small doclists while
+** making it efficient to directly access large doclists.  The
+** assumption is that large doclists represent terms which are more
+** likely to be query targets.
+**
+** TODO(shess) It may be useful for blocking decisions to be more
+** dynamic.  For instance, it may make more sense to have a 2.5k leaf
+** node rather than splitting into 2k and .5k nodes.  My intuition is
+** that this might extend through 2x or 4x the pagesize.
+**
+**
+**** Segment interior nodes ****
+** Segment interior nodes store blockids for subtree nodes and terms
+** to describe what data is stored by the each subtree.  Interior
+** nodes are written using InteriorWriter, and read using
+** InteriorReader.  InteriorWriters are created as needed when
+** SegmentWriter creates new leaf nodes, or when an interior node
+** itself grows too big and must be split.  The format of interior
+** nodes:
+**
+** varint iHeight;           (height from leaf level, always >0)
+** varint iBlockid;          (block id of node's leftmost subtree)
+** optional {
+**   varint nTerm;           (length of first term)
+**   char pTerm[nTerm];      (content of first term)
+**   array {
+**                                (further terms are delta-encoded)
+**     varint nPrefix;            (length of shared prefix with previous term)
+**     varint nSuffix;            (length of unshared suffix)
+**     char pTermSuffix[nSuffix]; (unshared suffix of next term)
+**   }
+** }
+**
+** Here, optional { X } means an optional element, while array { X }
+** means zero or more occurrences of X, adjacent in memory.
+**
+** An interior node encodes n terms separating n+1 subtrees.  The
+** subtree blocks are contiguous, so only the first subtree's blockid
+** is encoded.  The subtree at iBlockid will contain all terms less
+** than the first term encoded (or all terms if no term is encoded).
+** Otherwise, for terms greater than or equal to pTerm[i] but less
+** than pTerm[i+1], the subtree for that term will be rooted at
+** iBlockid+i.  Interior nodes only store enough term data to
+** distinguish adjacent children (if the rightmost term of the left
+** child is "something", and the leftmost term of the right child is
+** "wicked", only "w" is stored).
+**
+** New data is spilled to a new interior node at the same height when
+** the current node exceeds INTERIOR_MAX bytes (default 2048).
+** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
+** interior nodes and making the tree too skinny.  The interior nodes
+** at a given height are naturally tracked by interior nodes at
+** height+1, and so on.
+**
+**
+**** Segment directory ****
+** The segment directory in table %_segdir stores meta-information for
+** merging and deleting segments, and also the root node of the
+** segment's tree.
+**
+** The root node is the top node of the segment's tree after encoding
+** the entire segment, restricted to ROOT_MAX bytes (default 1024).
+** This could be either a leaf node or an interior node.  If the top
+** node requires more than ROOT_MAX bytes, it is flushed to %_segments
+** and a new root interior node is generated (which should always fit
+** within ROOT_MAX because it only needs space for 2 varints, the
+** height and the blockid of the previous root).
+**
+** The meta-information in the segment directory is:
+**   level               - segment level (see below)
+**   idx                 - index within level
+**                       - (level,idx uniquely identify a segment)
+**   start_block         - first leaf node
+**   leaves_end_block    - last leaf node
+**   end_block           - last block (including interior nodes)
+**   root                - contents of root node
+**
+** If the root node is a leaf node, then start_block,
+** leaves_end_block, and end_block are all 0.
+**
+**
+**** Segment merging ****
+** To amortize update costs, segments are grouped into levels and
+** merged in batches.  Each increase in level represents exponentially
+** more documents.
+**
+** New documents (actually, document updates) are tokenized and
+** written individually (using LeafWriter) to a level 0 segment, with
+** incrementing idx.  When idx reaches MERGE_COUNT (default 16), all
+** level 0 segments are merged into a single level 1 segment.  Level 1
+** is populated like level 0, and eventually MERGE_COUNT level 1
+** segments are merged to a single level 2 segment (representing
+** MERGE_COUNT^2 updates), and so on.
+**
+** A segment merge traverses all segments at a given level in
+** parallel, performing a straightforward sorted merge.  Since segment
+** leaf nodes are written in to the %_segments table in order, this
+** merge traverses the underlying sqlite disk structures efficiently.
+** After the merge, all segment blocks from the merged level are
+** deleted.
+**
+** MERGE_COUNT controls how often we merge segments.  16 seems to be
+** somewhat of a sweet spot for insertion performance.  32 and 64 show
+** very similar performance numbers to 16 on insertion, though they're
+** a tiny bit slower (perhaps due to more overhead in merge-time
+** sorting).  8 is about 20% slower than 16, 4 about 50% slower than
+** 16, 2 about 66% slower than 16.
+**
+** At query time, high MERGE_COUNT increases the number of segments
+** which need to be scanned and merged.  For instance, with 100k docs
+** inserted:
+**
+**    MERGE_COUNT   segments
+**       16           25
+**        8           12
+**        4           10
+**        2            6
+**
+** This appears to have only a moderate impact on queries for very
+** frequent terms (which are somewhat dominated by segment merge
+** costs), and infrequent and non-existent terms still seem to be fast
+** even with many segments.
+**
+** TODO(shess) That said, it would be nice to have a better query-side
+** argument for MERGE_COUNT of 16.  Also, it is possible/likely that
+** optimizations to things like doclist merging will swing the sweet
+** spot around.
+**
+**
+**
+**** Handling of deletions and updates ****
+** Since we're using a segmented structure, with no docid-oriented
+** index into the term index, we clearly cannot simply update the term
+** index when a document is deleted or updated.  For deletions, we
+** write an empty doclist (varint(docid) varint(POS_END)), for updates
+** we simply write the new doclist.  Segment merges overwrite older
+** data for a particular docid with newer data, so deletes or updates
+** will eventually overtake the earlier data and knock it out.  The
+** query logic likewise merges doclists so that newer data knocks out
+** older data.

+** config=xxx option (i.e. "xxx"). This function queries the database for
+** a table of that name. If found, the output variables are populated
+** as follows:

+**   *pnCol:   Set to the number of columns table xxx has,
+**
+**   *pnStr:   Set to the total amount of space required to store a copy
+**             of each columns name, including the nul-terminator.
+**
+**   *pazCol:  Set to point to an array of *pnCol strings. Each string is
+**             the name of the corresponding column in table xxx. The array
+**             and its contents are allocated using a single allocation. It
+**             is the responsibility of the caller to free this allocation
+**             by eventually passing the *pazCol value to sqlite3_free().
+**
+** If the table cannot be found, an error code is returned and the output
+** variables are undefined. Or, if an OOM is encountered, SQLITE_NOMEM is

+**      where "*" may match any single token. The position list in this case
+**      is populated as for "A * C" before returning.
+**
+**   2. NEAR is treated as AND. If the expression is "x NEAR y", it is

+** By default, this module parses the legacy syntax that has been
+** traditionally used by fts3. Or, if SQLITE_ENABLE_FTS3_PARENTHESIS
+** is defined, then it uses the new syntax. The differences between
+** the new and the old syntaxes are:
+**
+**  a) The new syntax supports parenthesis. The old does not.
+**
+**  b) The new syntax supports the AND and NOT operators. The old does not.
+**
+**  c) The old syntax supports the "-" token qualifier. This is not
+**     supported by the new syntax (it is replaced by the NOT operator).
+**
+**  d) When using the old syntax, the OR operator has a greater precedence
+**     than an implicit AND. When using the new, both implicity and explicit
+**     AND operators have a higher precedence than OR.
+**
+** If compiled with SQLITE_TEST defined, then this module exports the
+** symbol "int sqlite3_fts3_enable_parentheses". Setting this variable
+** to zero causes the module to use the old syntax. If it is set to
+** non-zero the new syntax is activated. This is so both syntaxes can
+** be tested using a single build of testfixture.
+**
+** The following describes the syntax supported by the fts3 MATCH
+** operator in a similar format to that used by the lemon parser
+** generator. This module does not use actually lemon, it uses a
+** custom parser.
+**
+**   query ::= andexpr (OR andexpr)*.
+**
+**   andexpr ::= notexpr (AND? notexpr)*.
+**
+**   notexpr ::= nearexpr (NOT nearexpr|-TOKEN)*.
+**   notexpr ::= LP query RP.
+**
+**   nearexpr ::= phrase (NEAR distance_opt nearexpr)*.
+**
+**   distance_opt ::= .
+**   distance_opt ::= / INTEGER.

+** Database Format of R-Tree Tables
+** --------------------------------
+**
+** The data structure for a single virtual r-tree table is stored in three
+** native SQLite tables declared as follows. In each case, the '%' character
+** in the table name is replaced with the user-supplied name of the r-tree
+** table.
+**
+**   CREATE TABLE %_node(nodeno INTEGER PRIMARY KEY, data BLOB)
+**   CREATE TABLE %_parent(nodeno INTEGER PRIMARY KEY, parentnode INTEGER)
+**   CREATE TABLE %_rowid(rowid INTEGER PRIMARY KEY, nodeno INTEGER, ...)
+**
+** The data for each node of the r-tree structure is stored in the %_node
+** table. For each node that is not the root node of the r-tree, there is
+** an entry in the %_parent table associating the node with its parent.
+** And for each row of data in the table, there is an entry in the %_rowid
+** table that maps from the entries rowid to the id of the node that it
+** is stored on.  If the r-tree contains auxiliary columns, those are stored
+** on the end of the %_rowid table.
+**
+** The root node of an r-tree always exists, even if the r-tree table is
+** empty. The nodeno of the root node is always 1. All other nodes in the
+** table must be the same size as the root node. The content of each node
+** is formatted as follows:
+**
+**   1. If the node is the root node (node 1), then the first 2 bytes
+**      of the node contain the tree depth as a big-endian integer.
+**      For non-root nodes, the first 2 bytes are left unused.
+**
+**   2. The next 2 bytes contain the number of entries currently
+**      stored in the node.
+**
+**   3. The remainder of the node contains the node entries. Each entry
+**      consists of a single 8-byte integer followed by an even number
+**      of 4-byte coordinates. For leaf nodes the integer is the rowid
+**      of a record. For internal nodes it is the node number of a
+**      child page.

+*************************************************************************
+**
+**
+** OVERVIEW
+**
+**  The RBU extension requires that the RBU update be packaged as an
+**  SQLite database. The tables it expects to find are described in
+**  sqlite3rbu.h.  Essentially, for each table xyz in the target database
+**  that the user wishes to write to, a corresponding data_xyz table is
+**  created in the RBU database and populated with one row for each row to
+**  update, insert or delete from the target table.
+**
+**  The update proceeds in three stages:
+**
+**  1) The database is updated. The modified database pages are written
+**     to a *-oal file. A *-oal file is just like a *-wal file, except
+**     that it is named "<database>-oal" instead of "<database>-wal".
+**     Because regular SQLite clients do not look for file named
+**     "<database>-oal", they go on using the original database in
+**     rollback mode while the *-oal file is being generated.
+**
+**     During this stage RBU does not update the database by writing
+**     directly to the target tables. Instead it creates "imposter"
+**     tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
+**     to update each b-tree individually. All updates required by each
+**     b-tree are completed before moving on to the next, and all
+**     updates are done in sorted key order.
+**
+**  2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
+**     location using a call to rename(2). Before doing this the RBU
+**     module takes an EXCLUSIVE lock on the database file, ensuring
+**     that there are no other active readers.
+**
+**     Once the EXCLUSIVE lock is released, any other database readers
+**     detect the new *-wal file and read the database in wal mode. At
+**     this point they see the new version of the database - including
+**     the updates made as part of the RBU update.
+**
+**  3) The new *-wal file is checkpointed. This proceeds in the same way
+**     as a regular database checkpoint, except that a single frame is
+**     checkpointed each time sqlite3rbu_step() is called. If the RBU
+**     handle is closed before the entire *-wal file is checkpointed,
+**     the checkpoint progress is saved in the RBU database and the
+**     checkpoint can be resumed by another RBU client at some point in
+**     the future.
+**
+** POTENTIAL PROBLEMS
+**
+**  The rename() call might not be portable. And RBU is not currently
+**  syncing the directory after renaming the file.
+**
+**  When state is saved, any commit to the *-oal file and the commit to
+**  the RBU update database are not atomic. So if the power fails at the
+**  wrong moment they might get out of sync. As the main database will be
+**  committed before the RBU update database this will likely either just
+**  pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE

+** SUMMARY
+**
+** Writing a transaction containing a large number of operations on
+** b-tree indexes that are collectively larger than the available cache
+** memory can be very inefficient.
+**
+** The problem is that in order to update a b-tree, the leaf page (at least)
+** containing the entry being inserted or deleted must be modified. If the
+** working set of leaves is larger than the available cache memory, then a
+** single leaf that is modified more than once as part of the transaction
+** may be loaded from or written to the persistent media multiple times.
+** Additionally, because the index updates are likely to be applied in
+** random order, access to pages within the database is also likely to be in
+** random order, which is itself quite inefficient.
+**
+** One way to improve the situation is to sort the operations on each index
+** by index key before applying them to the b-tree. This leads to an IO
+** pattern that resembles a single linear scan through the index b-tree,
+** and all but guarantees each modified leaf page is loaded and stored
+** exactly once. SQLite uses this trick to improve the performance of
+** CREATE INDEX commands. This extension allows it to be used to improve
+** the performance of large transactions on existing databases.
+**
+** Additionally, this extension allows the work involved in writing the
+** large transaction to be broken down into sub-transactions performed
+** sequentially by separate processes. This is useful if the system cannot
+** guarantee that a single update process will run for long enough to apply
+** the entire update, for example because the update is being applied on a
+** mobile device that is frequently rebooted. Even after the writer process
+** has committed one or more sub-transactions, other database clients continue
+** to read from the original database snapshot. In other words, partially
+** applied transactions are not visible to other clients.
+**
+** "RBU" stands for "Resumable Bulk Update". As in a large database update
+** transmitted via a wireless network to a mobile device. A transaction
+** applied using this extension is hence refered to as an "RBU update".
+**
+**
+** LIMITATIONS
+**
+** An "RBU update" transaction is subject to the following limitations:
+**
+**   * The transaction must consist of INSERT, UPDATE and DELETE operations
+**     only.
+**
+**   * INSERT statements may not use any default values.
+**
+**   * UPDATE and DELETE statements must identify their target rows by
+**     non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
+**     KEY fields may not be updated or deleted. If the table being written
+**     has no PRIMARY KEY, affected rows must be identified by rowid.
+**
+**   * UPDATE statements may not modify PRIMARY KEY columns.
+**
+**   * No triggers will be fired.
+**
+**   * No foreign key violations are detected or reported.
+**
+**   * CHECK constraints are not enforced.
+**
+**   * No constraint handling mode except for "OR ROLLBACK" is supported.
+**
+**
+** PREPARATION
+**
+** An "RBU update" is stored as a separate SQLite database. A database
+** containing an RBU update is an "RBU database". For each table in the
+** target database to be updated, the RBU database should contain a table
+** named "data_<target name>" containing the same set of columns as the
+** target table, and one more - "rbu_control". The data_% table should
+** have no PRIMARY KEY or UNIQUE constraints, but each column should have
+** the same type as the corresponding column in the target database.
+** The "rbu_control" column should have no type at all. For example, if
+** the target database contains:
+**
+**   CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
+**
+** Then the RBU database should contain:
+**
+**   CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
+**
+** The order of the columns in the data_% table does not matter.
+**
+** Instead of a regular table, the RBU database may also contain virtual
+** tables or view named using the data_<target> naming scheme.
+**
+** Instead of the plain data_<target> naming scheme, RBU database tables
+** may also be named data<integer>_<target>, where <integer> is any sequence
+** of zero or more numeric characters (0-9). This can be significant because
+** tables within the RBU database are always processed in order sorted by
+** name. By judicious selection of the <integer> portion of the names
+** of the RBU tables the user can therefore control the order in which they
+** are processed. This can be useful, for example, to ensure that "external
+** content" FTS4 tables are updated before their underlying content tables.
+**
+** If the target database table is a virtual table or a table that has no
+** PRIMARY KEY declaration, the data_% table must also contain a column
+** named "rbu_rowid". This column is mapped to the tables implicit primary
+** key column - "rowid". Virtual tables for which the "rowid" column does
+** not function like a primary key value cannot be updated using RBU. For
+** example, if the target db contains either of the following:
+**
+**   CREATE VIRTUAL TABLE x1 USING fts3(a, b);
+**   CREATE TABLE x1(a, b)
+**
+** then the RBU database should contain:
+**
+**   CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
+**
+** All non-hidden columns (i.e. all columns matched by "SELECT *") of the
+** target table must be present in the input table. For virtual tables,
+** hidden columns are optional - they are updated by RBU if present in
+** the input table, or not otherwise. For example, to write to an fts4
+** table with a hidden languageid column such as:
+**
+**   CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
+**
+** Either of the following input table schemas may be used:
+**
+**   CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
+**   CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
+**
+** For each row to INSERT into the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain integer value 0. The
+** other columns should be set to the values that make up the new record
+** to insert.
+**
+** If the target database table has an INTEGER PRIMARY KEY, it is not
+** possible to insert a NULL value into the IPK column. Attempting to
+** do so results in an SQLITE_MISMATCH error.
+**
+** For each row to DELETE from the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain integer value 1. The
+** real primary key values of the row to delete should be stored in the
+** corresponding columns of the data_% table. The values stored in the
+** other columns are not used.
+**
+** For each row to UPDATE from the target database as part of the RBU
+** update, the corresponding data_% table should contain a single record
+** with the "rbu_control" column set to contain a value of type text.
+** The real primary key values identifying the row to update should be
+** stored in the corresponding columns of the data_% table row, as should
+** the new values of all columns being update. The text value in the
+** "rbu_control" column must contain the same number of characters as
+** there are columns in the target database table, and must consist entirely
+** of 'x' and '.' characters (or in some special cases 'd' - see below). For
+** each column that is being updated, the corresponding character is set to
+** 'x'. For those that remain as they are, the corresponding character of the
+** rbu_control value should be set to '.'. For example, given the tables
+** above, the update statement:
+**
+**   UPDATE t1 SET c = 'usa' WHERE a = 4;
+**
+** is represented by the data_t1 row created by:
+**
+**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
+**
+** Instead of an 'x' character, characters of the rbu_control value specified
+** for UPDATEs may also be set to 'd'. In this case, instead of updating the
+** target table with the value stored in the corresponding data_% column, the
+** user-defined SQL function "rbu_delta()" is invoked and the result stored in
+** the target table column. rbu_delta() is invoked with two arguments - the
+** original value currently stored in the target table column and the
+** value specified in the data_xxx table.
+**
+** For example, this row:
+**
+**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
+**
+** is similar to an UPDATE statement such as:
+**
+**   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
+**
+** Finally, if an 'f' character appears in place of a 'd' or 's' in an
+** ota_control string, the contents of the data_xxx table column is assumed
+** to be a "fossil delta" - a patch to be applied to a blob value in the
+** format used by the fossil source-code management system. In this case
+** the existing value within the target database table must be of type BLOB.
+** It is replaced by the result of applying the specified fossil delta to
+** itself.
+**
+** If the target database table is a virtual table or a table with no PRIMARY
+** KEY, the rbu_control value should not include a character corresponding
+** to the rbu_rowid value. For example, this:
+**
+**   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control)
+**       VALUES(NULL, 'usa', 12, '.x');
+**
+** causes a result similar to:
+**
+**   UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
+**
+** The data_xxx tables themselves should have no PRIMARY KEY declarations.
+** However, RBU is more efficient if reading the rows in from each data_xxx
+** table in "rowid" order is roughly the same as reading them sorted by
+** the PRIMARY KEY of the corresponding target database table. In other
+** words, rows should be sorted using the destination table PRIMARY KEY
+** fields before they are inserted into the data_xxx tables.
+**
+** USAGE
+**
+** The API declared below allows an application to apply an RBU update
+** stored on disk to an existing target database. Essentially, the
+** application:
+**
+**     1) Opens an RBU handle using the sqlite3rbu_open() function.
+**
+**     2) Registers any required virtual table modules with the database
+**        handle returned by sqlite3rbu_db(). Also, if required, register
+**        the rbu_delta() implementation.
+**
+**     3) Calls the sqlite3rbu_step() function one or more times on
+**        the new handle. Each call to sqlite3rbu_step() performs a single
+**        b-tree operation, so thousands of calls may be required to apply
+**        a complete update.
+**
+**     4) Calls sqlite3rbu_close() to close the RBU update handle. If
+**        sqlite3rbu_step() has been called enough times to completely
+**        apply the update to the target database, then the RBU database
+**        is marked as fully applied. Otherwise, the state of the RBU
+**        update application is saved in the RBU database for later
+**        resumption.
+**
+** See comments below for more detail on APIs.
+**
+** If an update is only partially applied to the target database by the
+** time sqlite3rbu_close() is called, various state information is saved
+** within the RBU database. This allows subsequent processes to automatically
+** resume the RBU update from where it left off.
+**
+** To remove all RBU extension state information, returning an RBU database
+** to its original contents, it is sufficient to drop all tables that begin
+** with the prefix "rbu_"
+**
+** DATABASE LOCKING
+**
+** An RBU update may not be applied to a database in WAL mode. Attempting
+** to do so is an error (SQLITE_ERROR).
+**
+** While an RBU handle is open, a SHARED lock may be held on the target
+** database file. This means it is possible for other clients to read the
+** database, but not to write it.
+**
+** If an RBU update is started and then suspended before it is completed,
+** then an external client writes to the database, then attempting to resume
+** the suspended RBU update is also an error (SQLITE_BUSY).

+** The new object is registered as a non-default VFS with SQLite before
+** returning.
+**
+** Part of the RBU implementation uses a custom VFS object. Usually, this
+** object is created and deleted automatically by RBU.
+**
+** The exception is for applications that also use zipvfs. In this case,
+** the custom VFS must be explicitly created by the user before the RBU
+** handle is opened. The RBU VFS should be installed so that the zipvfs
+** VFS uses the RBU VFS, which in turn uses any other VFS layers in use
+** (for example multiplexor) to access the file-system. For example,
+** to assemble an RBU enabled VFS stack that uses both zipvfs and
+** multiplexor (error checking omitted):
+**
+**     // Create a VFS named "multiplex" (not the default).
+**     sqlite3_multiplex_initialize(0, 0);
+**
+**     // Create an rbu VFS named "rbu" that uses multiplexor. If the
+**     // second argument were replaced with NULL, the "rbu" VFS would
+**     // access the file-system via the system default VFS, bypassing the
+**     // multiplexor.
+**     sqlite3rbu_create_vfs("rbu", "multiplex");
+**
+**     // Create a zipvfs VFS named "zipvfs" that uses rbu.
+**     zipvfs_create_vfs_v3("zipvfs", "rbu", 0, xCompressorAlgorithmDetector);
+**
+**     // Make zipvfs the default VFS.
+**     sqlite3_vfs_register(sqlite3_vfs_find("zipvfs"), 1);
+**
+** Because the default VFS created above includes a RBU functionality, it
+** may be used by RBU clients. Attempting to use RBU with a zipvfs VFS stack
+** that does not include the RBU layer results in an error.
+**
+** The overhead of adding the "rbu" VFS to the system is negligible for
+** non-RBU users. There is no harm in an application accessing the
+** file-system via "rbu" all the time, even if it only uses RBU functionality

+/**************************************************************************
+** Beginning of RBU VFS shim methods. The VFS shim modifies the behaviour
+** of a standard VFS in the following ways:
+**
+** 1. Whenever the first page of a main database file is read or
+**    written, the value of the change-counter cookie is stored in
+**    rbu_file.iCookie. Similarly, the value of the "write-version"
+**    database header field is stored in rbu_file.iWriteVer. This ensures
+**    that the values are always trustworthy within an open transaction.
+**
+** 2. Whenever an SQLITE_OPEN_WAL file is opened, the (rbu_file.pWalFd)
+**    member variable of the associated database file descriptor is set
+**    to point to the new file. A mutex protected linked list of all main
+**    db fds opened using a particular RBU VFS is maintained at
+**    rbu_vfs.pMain to facilitate this.
+**
+** 3. Using a new file-control "SQLITE_FCNTL_RBU", a main db rbu_file
+**    object can be marked as the target database of an RBU update. This
+**    turns on the following extra special behaviour:
+**
+** 3a. If xAccess() is called to check if there exists a *-wal file
+**     associated with an RBU target database currently in RBU_STAGE_OAL
+**     stage (preparing the *-oal file), the following special handling
+**     applies:
+**
+**      * if the *-wal file does exist, return SQLITE_CANTOPEN. An RBU
+**        target database may not be in wal mode already.
+**
+**      * if the *-wal file does not exist, set the output parameter to
+**        non-zero (to tell SQLite that it does exist) anyway.
+**
+**     Then, when xOpen() is called to open the *-wal file associated with
+**     the RBU target in RBU_STAGE_OAL stage, instead of opening the *-wal
+**     file, the rbu vfs opens the corresponding *-oal file instead.
+**
+** 3b. The *-shm pages returned by xShmMap() for a target db file in
+**     RBU_STAGE_OAL mode are actually stored in heap memory. This is to
+**     avoid creating a *-shm file on disk. Additionally, xShmLock() calls
+**     are no-ops on target database files in RBU_STAGE_OAL mode. This is
+**     because assert() statements in some VFS implementations fail if
+**     xShmLock() is called before xShmMap().
+**
+** 3c. If an EXCLUSIVE lock is attempted on a target database file in any
+**     mode except RBU_STAGE_DONE (all work completed and checkpointed), it
+**     fails with an SQLITE_BUSY error. This is to stop RBU connections
+**     from automatically checkpointing a *-wal (or *-oal) file from within
+**     sqlite3_close().
+**
+** 3d. In RBU_STAGE_CAPTURE mode, all xRead() calls on the wal file, and
+**     all xWrite() calls on the target database file perform no IO.
+**     Instead the frame and page numbers that would be read and written
+**     are recorded. Additionally, successful attempts to obtain exclusive
+**     xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target
+**     database file are recorded. xShmLock() calls to unlock the same
+**     locks are no-ops (so that once obtained, these locks are never
+**     relinquished). Finally, calls to xSync() on the target database
+**     file fail with SQLITE_INTERNAL errors.

+** Page paths:
+**
+**   The value of the 'path' column describes the path taken from the
+**   root-node of the b-tree structure to each page. The value of the
+**   root-node path is '/'.
+**
+**   The value of the path for the left-most child page of the root of
+**   a b-tree is '/000/'. (Btrees store content ordered from left to right
+**   so the pages to the left have smaller keys than the pages to the right.)
+**   The next to left-most child of the root page is
+**   '/001', and so on, each sibling page identified by a 3-digit hex
+**   value. The children of the 451st left-most sibling have paths such
+**   as '/1c2/000/, '/1c2/001/' etc.
+**
+**   Overflow pages are specified by appending a '+' character and a
+**   six-digit hexadecimal value to the path to the cell they are linked
+**   from. For example, the three overflow pages in a chain linked from
+**   the left-most cell of the 450th child of the root page are identified
+**   by the paths:
+**
+**      '/1c2/000+000000'         // First page in overflow chain
+**      '/1c2/000+000001'         // Second page in overflow chain
+**      '/1c2/000+000002'         // Third page in overflow chain
+**
+**   If the paths are sorted using the BINARY collation sequence, then
+**   the overflow pages associated with a cell will appear earlier in the
+**   sort-order than its child page:
+**
+**      '/1c2/000/'               // Left-most child of 451st child of root

+**
+** This file contains an implementation of the "sqlite_dbpage" virtual table.
+**
+** The sqlite_dbpage virtual table is used to read or write whole raw
+** pages of the database file.  The pager interface is used so that
+** uncommitted changes and changes recorded in the WAL file are correctly
+** retrieved.
+**
+** Usage example:
+**
+**    SELECT data FROM sqlite_dbpage('aux1') WHERE pgno=123;
+**
+** This is an eponymous virtual table so it does not need to be created before
+** use.  The optional argument to the sqlite_dbpage() table name is the
+** schema for the database file that is to be read.  The default schema is
+** "main".
+**
+** The data field of sqlite_dbpage table can be updated.  The new
+** value must be a BLOB which is the correct page size, otherwise the
+** update fails.  Rows may not be deleted or inserted.

+** RECORD FORMAT:
+**
+** The following record format is similar to (but not compatible with) that
+** used in SQLite database files. This format is used as part of the
+** change-set binary format, and so must be architecture independent.
+**
+** Unlike the SQLite database record format, each field is self-contained -
+** there is no separation of header and data. Each field begins with a
+** single byte describing its type, as follows:
+**
+**       0x00: Undefined value.
+**       0x01: Integer value.
+**       0x02: Real value.
+**       0x03: Text value.
+**       0x04: Blob value.
+**       0x05: SQL NULL value.
+**
+** Note that the above match the definitions of SQLITE_INTEGER, SQLITE_TEXT
+** and so on in sqlite3.h. For undefined and NULL values, the field consists
+** only of the single type byte. For other types of values, the type byte
+** is followed by:
+**
+**   Text values:
+**     A varint containing the number of bytes in the value (encoded using
+**     UTF-8). Followed by a buffer containing the UTF-8 representation
+**     of the text value. There is no nul terminator.
+**
+**   Blob values:
+**     A varint containing the number of bytes in the value, followed by
+**     a buffer containing the value itself.
+**
+**   Integer values:
+**     An 8-byte big-endian integer value.
+**
+**   Real values:
+**     An 8-byte big-endian IEEE 754-2008 real value.
+**
+** Varint values are encoded in the same way as varints in the SQLite
+** record format.
+**
+** CHANGESET FORMAT:
+**
+** A changeset is a collection of DELETE, UPDATE and INSERT operations on
+** one or more tables. Operations on a single table are grouped together,
+** but may occur in any order (i.e. deletes, updates and inserts are all
+** mixed together).
+**
+** Each group of changes begins with a table header:
+**
+**   1 byte: Constant 0x54 (capital 'T')
+**   Varint: Number of columns in the table.
+**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
+**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
+**
+** Followed by one or more changes to the table.
+**
+**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
+**   1 byte: The "indirect-change" flag.
+**   old.* record: (delete and update only)
+**   new.* record: (insert and update only)
+**
+** The "old.*" and "new.*" records, if present, are N field records in the
+** format described above under "RECORD FORMAT", where N is the number of
+** columns in the table. The i'th field of each record is associated with
+** the i'th column of the table, counting from left to right in the order
+** in which columns were declared in the CREATE TABLE statement.
+**
+** The new.* record that is part of each INSERT change contains the values
+** that make up the new row. Similarly, the old.* record that is part of each
+** DELETE change contains the values that made up the row that was deleted
+** from the database. In the changeset format, the records that are part
+** of INSERT or DELETE changes never contain any undefined (type byte 0x00)
+** fields.
+**
+** Within the old.* record associated with an UPDATE change, all fields
+** associated with table columns that are not PRIMARY KEY columns and are
+** not modified by the UPDATE change are set to "undefined". Other fields
+** are set to the values that made up the row before the UPDATE that the
+** change records took place. Within the new.* record, fields associated
+** with table columns modified by the UPDATE change contain the new
+** values. Fields associated with table columns that are not modified
+** are set to "undefined".
+**
+** PATCHSET FORMAT:
+**
+** A patchset is also a collection of changes. It is similar to a changeset,
+** but leaves undefined those fields that are not useful if no conflict
+** resolution is required when applying the changeset.
+**
+** Each group of changes begins with a table header:
+**
+**   1 byte: Constant 0x50 (capital 'P')
+**   Varint: Number of columns in the table.
+**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
+**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
+**
+** Followed by one or more changes to the table.
+**
+**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
+**   1 byte: The "indirect-change" flag.
+**   single record: (PK fields for DELETE, PK and modified fields for UPDATE,
+**                   full record for INSERT).
+**
+** As in the changeset format, each field of the single record that is part
+** of a patchset change is associated with the correspondingly positioned
+** table column, counting from left to right within the CREATE TABLE
+** statement.
+**
+** For a DELETE change, all fields within the record except those associated
+** with PRIMARY KEY columns are omitted. The PRIMARY KEY fields contain the
+** values identifying the row to delete.
+**
+** For an UPDATE change, all fields except those associated with PRIMARY KEY
+** columns and columns that are modified by the UPDATE are set to "undefined".
+** PRIMARY KEY fields contain the values identifying the table row to update,
+** and fields associated with modified columns contain the new column values.
+**
+** The records associated with INSERT changes are in the same format as for
+** changesets. It is not possible for a record associated with an INSERT
+** change to contain a field set to "undefined".
+**
+** REBASE BLOB FORMAT:
+**
+** A rebase blob may be output by sqlite3changeset_apply_v2() and its
+** streaming equivalent for use with the sqlite3_rebaser APIs to rebase
+** existing changesets. A rebase blob contains one entry for each conflict
+** resolved using either the OMIT or REPLACE strategies within the apply_v2()
+** call.
+**
+** The format used for a rebase blob is very similar to that used for
+** changesets. All entries related to a single table are grouped together.
+**
+** Each group of entries begins with a table header in changeset format:
+**
+**   1 byte: Constant 0x54 (capital 'T')
+**   Varint: Number of columns in the table.
+**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
+**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
+**
+** Followed by one or more entries associated with the table.
+**
+**   1 byte: Either SQLITE_INSERT (0x12), DELETE (0x09).
+**   1 byte: Flag. 0x01 for REPLACE, 0x00 for OMIT.
+**   record: (in the record format defined above).
+**
+** In a rebase blob, the first field is set to SQLITE_INSERT if the change
+** that caused the conflict was an INSERT or UPDATE, or to SQLITE_DELETE if
+** it was a DELETE. The second field is set to 0x01 if the conflict
+** resolution strategy was REPLACE, or 0x00 if it was OMIT.
+**
+** If the change that caused the conflict was a DELETE, then the single
+** record is a copy of the old.* record from the original changeset. If it
+** was an INSERT, then the single record is a copy of the new.* record. If
+** the conflicting change was an UPDATE, then the single record is a copy
+** of the new.* record with the PK fields filled in based on the original
+** old.* record.

+** EXTENSION API FUNCTIONS
+**
+** xUserData(pFts):
+**   Return a copy of the context pointer the extension function was
+**   registered with.
+**
+** xColumnTotalSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the FTS5 table. Or, if iCol is
+**   non-negative but less than the number of columns in the table, return
+**   the total number of tokens in column iCol, considering all rows in
+**   the FTS5 table.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+** xColumnCount(pFts):
+**   Return the number of columns in the table.
+**
+** xColumnSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the current row. Or, if iCol is
+**   non-negative but less than the number of columns in the table, set
+**   *pnToken to the number of tokens in column iCol of the current row.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+**   This function may be quite inefficient if used with an FTS5 table
+**   created with the "columnsize=0" option.
+**
+** xColumnText:
+**   This function attempts to retrieve the text of column iCol of the
+**   current document. If successful, (*pz) is set to point to a buffer
+**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+**   if an error occurs, an SQLite error code is returned and the final values
+**   of (*pz) and (*pn) are undefined.
+**
+** xPhraseCount:
+**   Returns the number of phrases in the current query expression.
+**
+** xPhraseSize:
+**   Returns the number of tokens in phrase iPhrase of the query. Phrases
+**   are numbered starting from zero.
+**
+** xInstCount:
+**   Set *pnInst to the total number of occurrences of all phrases within
+**   the query within the current row. Return SQLITE_OK if successful, or
+**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always returns 0.
+**
+** xInst:
+**   Query for the details of phrase match iIdx within the current row.
+**   Phrase matches are numbered starting from zero, so the iIdx argument
+**   should be greater than or equal to zero and smaller than the value
+**   output by xInstCount().
+**
+**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
+**   to the column in which it occurs and *piOff the token offset of the
+**   first token of the phrase. Returns SQLITE_OK if successful, or an error
+**   code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option.
+**
+** xRowid:
+**   Returns the rowid of the current row.
+**
+** xTokenize:
+**   Tokenize text using the tokenizer belonging to the FTS5 table.
+**
+** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+**   This API function is used to query the FTS table for phrase iPhrase
+**   of the current query. Specifically, a query equivalent to:
+**
+**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+**
+**   with $p set to a phrase equivalent to the phrase iPhrase of the
+**   current query is executed. Any column filter that applies to
+**   phrase iPhrase of the current query is included in $p. For each
+**   row visited, the callback function passed as the fourth argument
+**   is invoked. The context and API objects passed to the callback
+**   function may be used to access the properties of each matched row.
+**   Invoking Api.xUserData() returns a copy of the pointer passed as
+**   the third argument to pUserData.
+**
+**   If the callback function returns any value other than SQLITE_OK, the
+**   query is abandoned and the xQueryPhrase function returns immediately.
+**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+**   Otherwise, the error code is propagated upwards.
+**
+**   If the query runs to completion without incident, SQLITE_OK is returned.
+**   Or, if some error occurs before the query completes or is aborted by
+**   the callback, an SQLite error code is returned.
+**
+**
+** xSetAuxdata(pFts5, pAux, xDelete)
+**
+**   Save the pointer passed as the second argument as the extension function's
+**   "auxiliary data". The pointer may then be retrieved by the current or any
+**   future invocation of the same fts5 extension function made as part of
+**   the same MATCH query using the xGetAuxdata() API.
+**
+**   Each extension function is allocated a single auxiliary data slot for
+**   each FTS query (MATCH expression). If the extension function is invoked
+**   more than once for a single FTS query, then all invocations share a
+**   single auxiliary data context.
+**
+**   If there is already an auxiliary data pointer when this function is
+**   invoked, then it is replaced by the new pointer. If an xDelete callback
+**   was specified along with the original pointer, it is invoked at this
+**   point.
+**
+**   The xDelete callback, if one is specified, is also invoked on the
+**   auxiliary data pointer after the FTS5 query has finished.
+**
+**   If an error (e.g. an OOM condition) occurs within this function,
+**   the auxiliary data is set to NULL and an error code returned. If the
+**   xDelete parameter was not NULL, it is invoked on the auxiliary data
+**   pointer before returning.
+**
+**
+** xGetAuxdata(pFts5, bClear)
+**
+**   Returns the current auxiliary data pointer for the fts5 extension
+**   function. See the xSetAuxdata() method for details.
+**
+**   If the bClear argument is non-zero, then the auxiliary data is cleared
+**   (set to NULL) before this function returns. In this case the xDelete,
+**   if any, is not invoked.
+**
+**
+** xRowCount(pFts5, pnRow)
+**
+**   This function is used to retrieve the total number of rows in the table.
+**   In other words, the same value that would be returned by:
+**
+**        SELECT count(*) FROM ftstable;
+**
+** xPhraseFirst()
+**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
+**   method, to iterate through all instances of a single query phrase within
+**   the current row. This is the same information as is accessible via the
+**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+**   to use, this API may be faster under some circumstances. To iterate
+**   through instances of phrase iPhrase, use the following code:
+**
+**       Fts5PhraseIter iter;
+**       int iCol, iOff;
+**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+**           iCol>=0;
+**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+**       ){
+**         // An instance of phrase iPhrase at offset iOff of column iCol
+**       }
+**
+**   The Fts5PhraseIter structure is defined above. Applications should not
+**   modify this structure directly - it should only be used as shown above
+**   with the xPhraseFirst() and xPhraseNext() API methods (and by
+**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always iterates
+**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
+**
+** xPhraseNext()
+**   See xPhraseFirst above.
+**
+** xPhraseFirstColumn()
+**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+**   and xPhraseNext() APIs described above. The difference is that instead
+**   of iterating through all instances of a phrase in the current row, these
+**   APIs are used to iterate through the set of columns in the current row
+**   that contain one or more instances of a specified phrase. For example:
+**
+**       Fts5PhraseIter iter;
+**       int iCol;
+**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+**           iCol>=0;
+**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+**       ){
+**         // Column iCol contains at least one instance of phrase iPhrase
+**       }
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" option. If the FTS5 table is created with either
+**   "detail=none" "content=" option (i.e. if it is a contentless table),
+**   then this API always iterates through an empty set (all calls to
+**   xPhraseFirstColumn() set iCol to -1).
+**
+**   The information accessed using this API and its companion
+**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+**   (or xInst/xInstCount). The chief advantage of this API is that it is
+**   significantly more efficient than those alternatives when used with
+**   "detail=column" tables.
+**
+** xPhraseNextColumn()
+**   See xPhraseFirstColumn above.

+** CUSTOM AUXILIARY FUNCTIONS
+*************************************************************************/
+
+/*************************************************************************
+** CUSTOM TOKENIZERS
+**
+** Applications may also register custom tokenizer types. A tokenizer
+** is registered by providing fts5 with a populated instance of the
+** following structure. All structure methods must be defined, setting
+** any member of the fts5_tokenizer struct to NULL leads to undefined
+** behaviour. The structure methods are expected to function as follows:
+**
+** xCreate:
+**   This function is used to allocate and initialize a tokenizer instance.
+**   A tokenizer instance is required to actually tokenize text.
+**
+**   The first argument passed to this function is a copy of the (void*)
+**   pointer provided by the application when the fts5_tokenizer object
+**   was registered with FTS5 (the third argument to xCreateTokenizer()).
+**   The second and third arguments are an array of nul-terminated strings
+**   containing the tokenizer arguments, if any, specified following the
+**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
+**   to create the FTS5 table.
+**
+**   The final argument is an output variable. If successful, (*ppOut)
+**   should be set to point to the new tokenizer handle and SQLITE_OK
+**   returned. If an error occurs, some value other than SQLITE_OK should
+**   be returned. In this case, fts5 assumes that the final value of *ppOut
+**   is undefined.
+**
+** xDelete:
+**   This function is invoked to delete a tokenizer handle previously
+**   allocated using xCreate(). Fts5 guarantees that this function will
+**   be invoked exactly once for each successful call to xCreate().
+**
+** xTokenize:
+**   This function is expected to tokenize the nText byte string indicated
+**   by argument pText. pText may or may not be nul-terminated. The first
+**   argument passed to this function is a pointer to an Fts5Tokenizer object
+**   returned by an earlier call to xCreate().
+**
+**   The second argument indicates the reason that FTS5 is requesting
+**   tokenization of the supplied text. This is always one of the following
+**   four values:
+**
+**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
+**            or removed from the FTS table. The tokenizer is being invoked to
+**            determine the set of tokens to add to (or delete from) the
+**            FTS index.
+**
+**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed
+**            against the FTS index. The tokenizer is being called to tokenize
+**            a bareword or quoted string specified as part of the query.
+**
+**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
+**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
+**            followed by a "*" character, indicating that the last token
+**            returned by the tokenizer will be treated as a token prefix.
+**
+**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to
+**            satisfy an fts5_api.xTokenize() request made by an auxiliary
+**            function. Or an fts5_api.xColumnSize() request made by the same
+**            on a columnsize=0 database.
+**   </ul>
+**
+**   For each token in the input string, the supplied callback xToken() must
+**   be invoked. The first argument to it should be a copy of the pointer
+**   passed as the second argument to xTokenize(). The third and fourth
+**   arguments are a pointer to a buffer containing the token text, and the
+**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
+**   of the first byte of and first byte immediately following the text from
+**   which the token is derived within the input.
+**
+**   The second argument passed to the xToken() callback ("tflags") should
+**   normally be set to 0. The exception is if the tokenizer supports
+**   synonyms. In this case see the discussion below for details.
+**
+**   FTS5 assumes the xToken() callback is invoked for each token in the
+**   order that they occur within the input text.
+**
+**   If an xToken() callback returns any value other than SQLITE_OK, then
+**   the tokenization should be abandoned and the xTokenize() method should
+**   immediately return a copy of the xToken() return value. Or, if the
+**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
+**   if an error occurs with the xTokenize() implementation itself, it
+**   may abandon the tokenization and return any error code other than
+**   SQLITE_OK or SQLITE_DONE.
+**
+** SYNONYM SUPPORT
+**
+**   Custom tokenizers may also support synonyms. Consider a case in which a
+**   user wishes to query for a phrase such as "first place". Using the
+**   built-in tokenizers, the FTS5 query 'first + place' will match instances
+**   of "first place" within the document set, but not alternative forms
+**   such as "1st place". In some applications, it would be better to match
+**   all instances of "first place" or "1st place" regardless of which form
+**   the user specified in the MATCH query text.
+**
+**   There are several ways to approach this in FTS5:
+**
+**   <ol><li> By mapping all synonyms to a single token. In this case, using
+**            the above example, this means that the tokenizer returns the
+**            same token for inputs "first" and "1st". Say that token is in
+**            fact "first", so that when the user inserts the document "I won
+**            1st place" entries are added to the index for tokens "i", "won",
+**            "first" and "place". If the user then queries for '1st + place',
+**            the tokenizer substitutes "first" for "1st" and the query works
+**            as expected.
+**
+**       <li> By querying the index for all synonyms of each query term
+**            separately. In this case, when tokenizing query text, the
+**            tokenizer may provide multiple synonyms for a single term
+**            within the document. FTS5 then queries the index for each
+**            synonym individually. For example, faced with the query:
+**
+**   <codeblock>
+**     ... MATCH 'first place'</codeblock>
+**
+**            the tokenizer offers both "1st" and "first" as synonyms for the
+**            first token in the MATCH query and FTS5 effectively runs a query
+**            similar to:
+**
+**   <codeblock>
+**     ... MATCH '(first OR 1st) place'</codeblock>
+**
+**            except that, for the purposes of auxiliary functions, the query
+**            still appears to contain just two phrases - "(first OR 1st)"
+**            being treated as a single phrase.
+**
+**       <li> By adding multiple synonyms for a single term to the FTS index.
+**            Using this method, when tokenizing document text, the tokenizer
+**            provides multiple synonyms for each token. So that when a
+**            document such as "I won first place" is tokenized, entries are
+**            added to the FTS index for "i", "won", "first", "1st" and
+**            "place".
+**
+**            This way, even if the tokenizer does not provide synonyms
+**            when tokenizing query text (it should not - to do so would be
+**            inefficient), it doesn't matter if the user queries for
+**            'first + place' or '1st + place', as there are entries in the
+**            FTS index corresponding to both forms of the first token.
+**   </ol>
+**
+**   Whether it is parsing document or query text, any call to xToken that
+**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
+**   is considered to supply a synonym for the previous token. For example,
+**   when parsing the document "I won first place", a tokenizer that supports
+**   synonyms would call xToken() 5 times, as follows:
+**
+**   <codeblock>
+**       xToken(pCtx, 0, "i",                      1,  0,  1);
+**       xToken(pCtx, 0, "won",                    3,  2,  5);
+**       xToken(pCtx, 0, "first",                  5,  6, 11);
+**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
+**       xToken(pCtx, 0, "place",                  5, 12, 17);
+**</codeblock>
+**
+**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
+**   xToken() is called. Multiple synonyms may be specified for a single token
+**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence.
+**   There is no limit to the number of synonyms that may be provided for a
+**   single token.
+**
+**   In many cases, method (1) above is the best approach. It does not add
+**   extra data to the FTS index or require FTS5 to query for multiple terms,
+**   so it is efficient in terms of disk space and query speed. However, it
+**   does not support prefix queries very well. If, as suggested above, the
+**   token "first" is substituted for "1st" by the tokenizer, then the query:
+**
+**   <codeblock>
+**     ... MATCH '1s*'</codeblock>
+**
+**   will not match documents that contain the token "1st" (as the tokenizer
+**   will probably not map "1s" to any prefix of "first").
+**
+**   For full prefix support, method (3) may be preferred. In this case,
+**   because the index contains entries for both "first" and "1st", prefix
+**   queries such as 'fi*' or '1s*' will match correctly. However, because
+**   extra entries are added to the FTS index, this method uses more space
+**   within the database.
+**
+**   Method (2) offers a midpoint between (1) and (3). Using this method,
+**   a query such as '1s*' will match documents that contain the literal
+**   token "1st", but not "first" (assuming the tokenizer is not able to
+**   provide synonyms for prefixes). However, a non-prefix query like '1st'
+**   will match against "1st" and "first". This method does not require
+**   extra disk space, as no extra entries are added to the FTS index.
+**   On the other hand, it may require more CPU cycles to run MATCH queries,
+**   as separate queries of the FTS index are required for each synonym.
+**
+**   When using methods (2) or (3), it is important that the tokenizer only
+**   provide synonyms when tokenizing document text (method (2)) or query
+**   text (method (3)), not both. Doing so will not cause any errors, but is
+**   inefficient.

+** various aspects of the generated parser.
+**    fts5YYCODETYPE         is the data type used to store the integer codes
+**                       that represent terminal and non-terminal symbols.
+**                       "unsigned char" is used if there are fewer than
+**                       256 symbols.  Larger types otherwise.
+**    fts5YYNOCODE           is a number of type fts5YYCODETYPE that is not used for
+**                       any terminal or nonterminal symbol.
+**    fts5YYFALLBACK         If defined, this indicates that one or more tokens
+**                       (also known as: "terminal symbols") have fall-back
+**                       values which should be used if the original symbol
+**                       would not parse.  This permits keywords to sometimes
+**                       be used as identifiers, for example.
+**    fts5YYACTIONTYPE       is the data type used for "action codes" - numbers
+**                       that indicate what to do in response to the next
+**                       token.
+**    sqlite3Fts5ParserFTS5TOKENTYPE     is the data type used for minor type for terminal
+**                       symbols.  Background: A "minor type" is a semantic
+**                       value associated with a terminal or non-terminal
+**                       symbols.  For example, for an "ID" terminal symbol,
+**                       the minor type might be the name of the identifier.
+**                       Each non-terminal can have a different minor type.
+**                       Terminal symbols all have the same minor type, though.
+**                       This macros defines the minor type for terminal
+**                       symbols.
+**    fts5YYMINORTYPE        is the data type used for all minor types.
+**                       This is typically a union of many types, one of
+**                       which is sqlite3Fts5ParserFTS5TOKENTYPE.  The entry in the union
+**                       for terminal symbols is called "fts5yy0".
+**    fts5YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
+**                       zero the stack is dynamically sized using realloc()
+**    sqlite3Fts5ParserARG_SDECL     A static variable declaration for the %extra_argument
+**    sqlite3Fts5ParserARG_PDECL     A parameter declaration for the %extra_argument
+**    sqlite3Fts5ParserARG_PARAM     Code to pass %extra_argument as a subroutine parameter
+**    sqlite3Fts5ParserARG_STORE     Code to store %extra_argument into fts5yypParser
+**    sqlite3Fts5ParserARG_FETCH     Code to extract %extra_argument from fts5yypParser
+**    sqlite3Fts5ParserCTX_*         As sqlite3Fts5ParserARG_ except for %extra_context
+**    fts5YYERRORSYMBOL      is the code number of the error symbol.  If not
+**                       defined, then do no error processing.
+**    fts5YYNSTATE           the combined number of states.
+**    fts5YYNRULE            the number of rules in the grammar
+**    fts5YYNFTS5TOKEN           Number of terminal symbols
+**    fts5YY_MAX_SHIFT       Maximum value for shift actions
+**    fts5YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
+**    fts5YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
+**    fts5YY_ERROR_ACTION    The fts5yy_action[] code for syntax error
+**    fts5YY_ACCEPT_ACTION   The fts5yy_action[] code for accept
+**    fts5YY_NO_ACTION       The fts5yy_action[] code for no-op
+**    fts5YY_MIN_REDUCE      Minimum value for reduce actions

+**
+** Suppose the action integer is N.  Then the action is determined as

+**
+**   0 <= N <= fts5YY_MAX_SHIFT             Shift N.  That is, push the lookahead

+**
+**   N between fts5YY_MIN_REDUCE            Reduce by rule N-fts5YY_MIN_REDUCE
+**     and fts5YY_MAX_REDUCE
+**
+** The action table is constructed as a single large table named fts5yy_action[].
+** Given state S and lookahead X, the action is computed as either:
+**
+**    (A)   N = fts5yy_action[ fts5yy_shift_ofst[S] + X ]
+**    (B)   N = fts5yy_default[S]
+**
+** The (A) formula is preferred.  The B formula is used instead if
+** fts5yy_lookahead[fts5yy_shift_ofst[S]+X] is not equal to X.
+**
+** The formulas above are for computing the action when the lookahead is
+** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
+** a reduce action) then the fts5yy_reduce_ofst[] array is used in place of
+** the fts5yy_shift_ofst[] array.
+**
+** The following are the tables generated in this section:
+**
+**  fts5yy_action[]        A single table containing all actions.
+**  fts5yy_lookahead[]     A table containing the lookahead for each entry in
+**                     fts5yy_action.  Used to detect hash collisions.
+**  fts5yy_shift_ofst[]    For each state, the offset into fts5yy_action for
+**                     shifting terminals.
+**  fts5yy_reduce_ofst[]   For each state, the offset into fts5yy_action for
+**                     shifting non-terminals after a reduce.
+**  fts5yy_default[]       Default action for each state.

+** Details:
+**
+** The %_data table managed by this module,
+**
+**     CREATE TABLE %_data(id INTEGER PRIMARY KEY, block BLOB);
+**
+** , contains the following 5 types of records. See the comments surrounding
+** the FTS5_*_ROWID macros below for a description of how %_data rowids are
+** assigned to each fo them.
+**
+** 1. Structure Records:
+**
+**   The set of segments that make up an index - the index structure - are
+**   recorded in a single record within the %_data table. The record consists
+**   of a single 32-bit configuration cookie value followed by a list of
+**   SQLite varints. If the FTS table features more than one index (because
+**   there are one or more prefix indexes), it is guaranteed that all share
+**   the same cookie value.
+**
+**   Immediately following the configuration cookie, the record begins with
+**   three varints:
+**
+**     + number of levels,
+**     + total number of segments on all levels,
+**     + value of write counter.
+**
+**   Then, for each level from 0 to nMax:
+**
+**     + number of input segments in ongoing merge.
+**     + total number of segments in level.
+**     + for each segment from oldest to newest:
+**         + segment id (always > 0)
+**         + first leaf page number (often 1, always greater than 0)
+**         + final leaf page number
+**
+** 2. The Averages Record:
+**
+**   A single record within the %_data table. The data is a list of varints.
+**   The first value is the number of rows in the index. Then, for each column
+**   from left to right, the total number of tokens in the column for all
+**   rows of the table.
+**
+** 3. Segment leaves:
+**
+**   TERM/DOCLIST FORMAT:
+**
+**     Most of each segment leaf is taken up by term/doclist data. The
+**     general format of term/doclist, starting with the first term
+**     on the leaf page, is:
+**
+**         varint : size of first term
+**         blob:    first term data
+**         doclist: first doclist
+**         zero-or-more {
+**           varint:  number of bytes in common with previous term
+**           varint:  number of bytes of new term data (nNew)
+**           blob:    nNew bytes of new term data
+**           doclist: next doclist
+**         }
+**
+**     doclist format:
+**
+**         varint:  first rowid
+**         poslist: first poslist
+**         zero-or-more {
+**           varint:  rowid delta (always > 0)
+**           poslist: next poslist
+**         }
+**
+**     poslist format:
+**
+**         varint: size of poslist in bytes multiplied by 2, not including
+**                 this field. Plus 1 if this entry carries the "delete" flag.
+**         collist: collist for column 0
+**         zero-or-more {
+**           0x01 byte
+**           varint: column number (I)
+**           collist: collist for column I
+**         }
+**
+**     collist format:
+**
+**         varint: first offset + 2
+**         zero-or-more {
+**           varint: offset delta + 2
+**         }
+**
+**   PAGE FORMAT
+**
+**     Each leaf page begins with a 4-byte header containing 2 16-bit
+**     unsigned integer fields in big-endian format. They are:
+**
+**       * The byte offset of the first rowid on the page, if it exists
+**         and occurs before the first term (otherwise 0).
+**
+**       * The byte offset of the start of the page footer. If the page
+**         footer is 0 bytes in size, then this field is the same as the
+**         size of the leaf page in bytes.
+**
+**     The page footer consists of a single varint for each term located
+**     on the page. Each varint is the byte offset of the current term
+**     within the page, delta-compressed against the previous value. In
+**     other words, the first varint in the footer is the byte offset of
+**     the first term, the second is the byte offset of the second less that
+**     of the first, and so on.
+**
+**     The term/doclist format described above is accurate if the entire
+**     term/doclist data fits on a single leaf page. If this is not the case,
+**     the format is changed in two ways:
+**
+**       + if the first rowid on a page occurs before the first term, it
+**         is stored as a literal value:
+**
+**             varint:  first rowid
+**
+**       + the first term on each page is stored in the same way as the
+**         very first term of the segment:
+**
+**             varint : size of first term
+**             blob:    first term data
+**
+** 5. Segment doclist indexes:
+**
+**   Doclist indexes are themselves b-trees, however they usually consist of
+**   a single leaf record only. The format of each doclist index leaf page
+**   is:
+**
+**     * Flags byte. Bits are:
+**         0x01: Clear if leaf is also the root page, otherwise set.
+**
+**     * Page number of fts index leaf page. As a varint.
+**
+**     * First rowid on page indicated by previous field. As a varint.
+**
+**     * A list of varints, one for each subsequent termless page. A
+**       positive delta if the termless page contains at least one rowid,
+**       or an 0x00 byte otherwise.
+**
+**   Internal doclist index nodes are:
+**
+**     * Flags byte. Bits are:
+**         0x01: Clear for root page, otherwise set.
+**
+**     * Page number of first child page. As a varint.
+**
+**     * Copy of first rowid on page indicated by previous field. As a varint.
+**
+**     * A list of delta-encoded varints - the first rowid on each subsequent
+**       child page.

+** NOTES ON TRANSACTIONS:
+**
+** SQLite invokes the following virtual table methods as transactions are
+** opened and closed by the user:
+**
+**     xBegin():    Start of a new transaction.
+**     xSync():     Initial part of two-phase commit.
+**     xCommit():   Final part of two-phase commit.
+**     xRollback(): Rollback the transaction.
+**
+** Anything that is required as part of a commit that may fail is performed
+** in the xSync() callback. Current versions of SQLite ignore any errors
+** returned by xCommit().
+**
+** And as sub-transactions are opened/closed:
+**
+**     xSavepoint(int S):  Open savepoint S.
+**     xRelease(int S):    Commit and close savepoint S.
+**     xRollbackTo(int S): Rollback to start of savepoint S.
+**
+** During a write-transaction the fts5_index.c module may cache some data
+** in-memory. It is flushed to disk whenever xSync(), xRelease() or
+** xSavepoint() is called. And discarded whenever xRollback() or xRollbackTo()
+** is called.
+**
+** Additionally, if SQLITE_DEBUG is defined, an instance of the following

+** is not required, but it is used in the assert() statements executed by
+** function fts5CheckTransactionState() (see below).

+** Implementation of the xBestIndex method for FTS5 tables. Within the

+**   1. A MATCH constraint against the table column.
+**   2. A MATCH constraint against the "rank" column.
+**   3. A MATCH constraint against some other column.
+**   4. An == constraint against the rowid column.
+**   5. A < or <= constraint against the rowid column.
+**   6. A > or >= constraint against the rowid column.
+**
+** Within the ORDER BY, the following are supported:
+**
+**   5. ORDER BY rank [ASC|DESC]
+**   6. ORDER BY rowid [ASC|DESC]
+**
+** Information for the xFilter call is passed via both the idxNum and
+** idxStr variables. Specifically, idxNum is a bitmask of the following
+** flags used to encode the ORDER BY clause:
+**
+**     FTS5_BI_ORDER_RANK
+**     FTS5_BI_ORDER_ROWID
+**     FTS5_BI_ORDER_DESC
+**
+** idxStr is used to encode data from the WHERE clause. For each argument
+** passed to the xFilter method, the following is appended to idxStr:
+**
+**   Match against table column:            "m"
+**   Match against rank column:             "r"
+**   Match against other column:            "M<column-number>"
+**   LIKE  against other column:            "L<column-number>"
+**   GLOB  against other column:            "G<column-number>"
+**   Equality constraint against the rowid: "="
+**   A < or <= against the rowid:           "<"
+**   A > or >= against the rowid:           ">"
+**
+** This function ensures that there is at most one "r" or "=". And that if
+** there exists an "=" then there is no "<" or ">".
+**
+** Costs are assigned as follows:
+**
+**  a) If an unusable MATCH operator is present in the WHERE clause, the
+**     cost is unconditionally set to 1e50 (a really big number).
+**
+**  a) If a MATCH operator is present, the cost depends on the other
+**     constraints also present. As follows:
+**
+**       * No other constraints:         cost=1000.0
+**       * One rowid range constraint:   cost=750.0
+**       * Both rowid range constraints: cost=500.0
+**       * An == rowid constraint:       cost=100.0
+**
+**  b) Otherwise, if there is no MATCH:
+**
+**       * No other constraints:         cost=1000000.0
+**       * One rowid range constraint:   cost=750000.0
+**       * Both rowid range constraints: cost=250000.0
+**       * An == rowid constraint:       cost=10.0
+**
+** Costs are not modified by the ORDER BY clause.

+** that allows an application to run multiple statements of SQL
+** without having to use a lot of C code.

+** ^The sqlite3_exec() interface runs zero or more UTF-8 encoded,

+** argument.  ^If the callback function of the 3rd argument to

+** coming out of the evaluated SQL statements.  ^The 4th argument to
+** sqlite3_exec() is relayed through to the 1st argument of each
+** callback invocation.  ^If the callback pointer to sqlite3_exec()
+** is NULL, then no callback is ever invoked and result rows are
+** ignored.
+**
+** ^If an error occurs while evaluating the SQL statements passed into
+** sqlite3_exec(), then execution of the current statement stops and
+** subsequent statements are skipped.  ^If the 5th parameter to sqlite3_exec()
+** is not NULL then any error message is written into memory obtained
+** from [sqlite3_malloc()] and passed back through the 5th parameter.
+** To avoid memory leaks, the application should invoke [sqlite3_free()]
+** on error message strings returned through the 5th parameter of
+** sqlite3_exec() after the error message string is no longer needed.
+** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
+** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
+** NULL before returning.
+**
+** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
+** routine returns SQLITE_ABORT without invoking the callback again and
+** without running any subsequent SQL statements.
+**
+** ^The 2nd argument to the sqlite3_exec() callback function is the
+** number of columns in the result.  ^The 3rd argument to the sqlite3_exec()
+** callback is an array of pointers to strings obtained as if from
+** [sqlite3_column_text()], one for each column.  ^If an element of a
+** result row is NULL then the corresponding string pointer for the
+** sqlite3_exec() callback is a NULL pointer.  ^The 4th argument to the
+** sqlite3_exec() callback is an array of pointers to strings where each
+** entry represents the name of corresponding result column as obtained
+** from [sqlite3_column_name()].
+**
+** ^If the 2nd parameter to sqlite3_exec() is a NULL pointer, a pointer

+** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
+** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
+** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
+** to NULL.
+**
+** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
+** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
+** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
+** flag may be ORed in to indicate that only the data of the file
+** and not its inode needs to be synced.
+**
+** The integer values to xLock() and xUnlock() are one of
+** <ul>
+** <li> [SQLITE_LOCK_NONE],
+** <li> [SQLITE_LOCK_SHARED],
+** <li> [SQLITE_LOCK_RESERVED],
+** <li> [SQLITE_LOCK_PENDING], or
+** <li> [SQLITE_LOCK_EXCLUSIVE].
+** </ul>
+** xLock() increases the lock. xUnlock() decreases the lock.
+** The xCheckReservedLock() method checks whether any database connection,
+** either in this process or in some other process, is holding a RESERVED,
+** PENDING, or EXCLUSIVE lock on the file.  It returns true
+** if such a lock exists and false otherwise.
+**
+** The xFileControl() method is a generic interface that allows custom
+** VFS implementations to directly control an open file using the
+** [sqlite3_file_control()] interface.  The second "op" argument is an
+** integer opcode.  The third argument is a generic pointer intended to
+** point to a structure that may contain arguments or space in which to
+** write return values.  Potential uses for xFileControl() might be
+** functions to enable blocking locks with timeouts, to change the
+** locking strategy (for example to use dot-file locks), to inquire
+** about the status of a lock, or to break stale locks.  The SQLite
+** core reserves all opcodes less than 100 for its own use.
+** A [file control opcodes | list of opcodes] less than 100 is available.
+** Applications that define a custom xFileControl method should use opcodes
+** greater than 100 to avoid conflicts.  VFS implementations should
+** return [SQLITE_NOTFOUND] for file control opcodes that they do not
+** recognize.
+**
+** The xSectorSize() method returns the sector size of the
+** device that underlies the file.  The sector size is the
+** minimum write that can be performed without disturbing
+** other bytes in the file.  The xDeviceCharacteristics()

+** The SQLITE_IOCAP_ATOMIC property means that all writes of

+** CAPI3REF: Standard File Control Opcodes

+**
+** These integer constants are opcodes for the xFileControl method
+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
+** interface.
+**
+** <ul>
+** <li>[[SQLITE_FCNTL_LOCKSTATE]]
+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and is only available when the SQLITE_TEST
+** compile-time option is used.
+**
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction.  This hint is not guaranteed to be accurate but it
+** is often close.  The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
+** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
+** implements [sqlite3_deserialize()] to set an upper bound on the size
+** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
+** If the integer pointed to is negative, then it is filled in with the
+** current limit.  Otherwise the limit is set to the larger of the value
+** of the integer pointed to and the current database size.  The integer
+** pointed to is set to the new limit.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
+**
+** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
+** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with the journal file (either
+** the [rollback journal] or the [write-ahead log]) for a particular database
+** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** No longer in use.
+**
+** <li>[[SQLITE_FCNTL_SYNC]]
+** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
+** sent to the VFS immediately before the xSync method is invoked on a
+** database file descriptor. Or, if the xSync method is not invoked
+** because the user has configured SQLite with
+** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
+** of the xSync method. In most cases, the pointer argument passed with
+** this file-control is NULL. However, if the database file is being synced
+** as part of a multi-database commit, the argument points to a nul-terminated
+** string containing the transactions super-journal file name. VFSes that
+** do not need this signal should silently ignore this opcode. Applications
+** should not call [sqlite3_file_control()] with this opcode as doing so may
+** disrupt the operation of the specialized VFSes that do require it.
+**
+** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
+** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
+** and sent to the VFS after a transaction has been committed immediately
+** but before the database is unlocked. VFSes that do not need this signal
+** should silently ignore this opcode. Applications should not call
+** [sqlite3_file_control()] with this opcode as doing so may disrupt the
+** operation of the specialized VFSes that do require it.
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs.  By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry.  This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted.  The values are changed for all database connections
+** within the same process.  The argument is a pointer to an array of two
+** integers where the first integer is the new retry count and the second
+** integer is the delay.  If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated.  The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
+** write ahead log ([WAL file]) and shared memory
+** files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes.  Setting persistent WAL mode causes those files to persist after
+** close.  Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable.  The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode.  If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode.  If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done.  As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything.  Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented.  This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_VFS_POINTER]]
+** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
+** [VFSes] currently in use.  ^(The argument X in
+** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
+** of type "[sqlite3_vfs] **".  This opcodes will set *X
+** to a pointer to the top-level VFS.)^
+** ^When there are multiple VFS shims in the stack, this opcode finds the
+** upper-most shim only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument.  ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
+** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement if result string is NULL, or that returns a copy
+** of the result string if the string is non-NULL.
+** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connection's busy-handler callback. The argument is of type (void**)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connection's
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses.  The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()].  The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map.  The
+** pointer is overwritten with the old value.  The limit is not changed if
+** the value originally pointed to is negative, and so the current limit
+** can be queried by passing in a pointer to a negative number.  This
+** file-control is used internally to implement [PRAGMA mmap_size].
+**
+** <li>[[SQLITE_FCNTL_TRACE]]
+** The [SQLITE_FCNTL_TRACE] file control provides advisory information
+** to the VFS about what the higher layers of the SQLite stack are doing.
+** This file control is used by some VFS activity tracing [shims].
+** The argument is a zero-terminated string.  Higher layers in the
+** SQLite stack may generate instances of this file control if
+** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
+**
+** <li>[[SQLITE_FCNTL_HAS_MOVED]]
+** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
+** pointer to an integer and it writes a boolean into that integer depending
+** on whether or not the file has been renamed, moved, or deleted since it
+** was first opened.
+**
+** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
+** underlying native file handle associated with a file handle.  This file
+** control interprets its argument as a pointer to a native file handle and
+** writes the resulting value there.
+**
+** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to swap the file handle with the one
+** pointed to by the pArg argument.  This capability is used during testing
+** and only needs to be supported when SQLITE_TEST is defined.
+**
+** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
+** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
+** be advantageous to block on the next WAL lock if the lock is not immediately
+** available.  The WAL subsystem issues this signal during rare
+** circumstances in order to fix a problem with priority inversion.
+** Applications should <em>not</em> use this file-control.
+**
+** <li>[[SQLITE_FCNTL_ZIPVFS]]
+** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
+** VFS should return SQLITE_NOTFOUND for this opcode.
+**
+** <li>[[SQLITE_FCNTL_RBU]]
+** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
+** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
+** this opcode.
+**
+** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
+** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
+** the file descriptor is placed in "batch write mode", which
+** means all subsequent write operations will be deferred and done
+** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
+** that do not support batch atomic writes will return SQLITE_NOTFOUND.
+** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
+** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
+** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
+** no VFS interface calls on the same [sqlite3_file] file descriptor
+** except for calls to the xWrite method and the xFileControl method
+** with [SQLITE_FCNTL_SIZE_HINT].
+**
+** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
+** This file control returns [SQLITE_OK] if and only if the writes were
+** all performed successfully and have been committed to persistent storage.
+** ^Regardless of whether or not it is successful, this file control takes
+** the file descriptor out of batch write mode so that all subsequent
+** write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
+** ^This file control takes the file descriptor out of batch write mode
+** so that all subsequent write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
+** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
+** to block for up to M milliseconds before failing when attempting to
+** obtain a file lock using the xLock or xShmLock methods of the VFS.
+** The parameter is a pointer to a 32-bit signed integer that contains
+** the value that M is to be set to. Before returning, the 32-bit signed
+** integer is overwritten with the previous value of M.
+**
+** <li>[[SQLITE_FCNTL_DATA_VERSION]]
+** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
+** a database file.  The argument is a pointer to a 32-bit unsigned integer.
+** The "data version" for the pager is written into the pointer.  The
+** "data version" changes whenever any change occurs to the corresponding
+** database file, either through SQL statements on the same database
+** connection or through transactions committed by separate database
+** connections possibly in other processes. The [sqlite3_total_changes()]
+** interface can be used to find if any database on the connection has changed,
+** but that interface responds to changes on TEMP as well as MAIN and does
+** not provide a mechanism to detect changes to MAIN only.  Also, the
+** [sqlite3_total_changes()] interface responds to internal changes only and
+** omits changes made by other database connections.  The
+** [PRAGMA data_version] command provides a mechanism to detect changes to
+** a single attached database that occur due to other database connections,
+** but omits changes implemented by the database connection on which it is
+** called.  This file control is the only mechanism to detect changes that
+** happen either internally or externally and that are associated with
+** a particular attached database.
+**
+** <li>[[SQLITE_FCNTL_CKPT_START]]
+** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
+** in wal mode before the client starts to copy pages from the wal
+** file to the database file.
+**
+** <li>[[SQLITE_FCNTL_CKPT_DONE]]
+** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
+** in wal mode after the client has finished copying pages from the wal
+** file to the database file, but before the *-shm file is updated to
+** record the fact that the pages have been checkpointed.
+** </ul>
+**
+** <li>[[SQLITE_FCNTL_EXTERNAL_READER]]
+** The EXPERIMENTAL [SQLITE_FCNTL_EXTERNAL_READER] opcode is used to detect
+** whether or not there is a database client in another process with a wal-mode
+** transaction open on the database or not. It is only available on unix.The
+** (void*) argument passed with this file-control should be a pointer to a
+** value of type (int). The integer value is set to 1 if the database is a wal
+** mode database and there exists at least one client in another process that
+** currently has an SQL transaction open on the database. It is set to 0 if
+** the database is not a wal-mode db, or if there is no such connection in any
+** other process. This opcode cannot be used to detect transactions opened
+** by clients within the current process, only within other processes.
+** </ul>
+**
+** <li>[[SQLITE_FCNTL_CKSM_FILE]]
+** Used by the cksmvfs VFS module only.

+/*
+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system.  The "vfs"
+** in the name of the object stands for "virtual file system".  See
+** the [VFS | VFS documentation] for further information.
+**
+** The VFS interface is sometimes extended by adding new methods onto
+** the end.  Each time such an extension occurs, the iVersion field
+** is incremented.  The iVersion value started out as 1 in
+** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
+** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
+** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
+** may be appended to the sqlite3_vfs object and the iVersion value
+** may increase again in future versions of SQLite.
+** Note that due to an oversight, the structure
+** of the sqlite3_vfs object changed in the transition from
+** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
+** and yet the iVersion field was not increased.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS.  mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer.  The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way.  The [sqlite3_vfs_find()] interface
+** searches the list.  Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify.  SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module.  The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file.  ^Whenever the
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()
+** call, depending on the object being opened:
+**
+** <ul>
+** <li>  [SQLITE_OPEN_MAIN_DB]
+** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
+** <li>  [SQLITE_OPEN_TEMP_DB]
+** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
+** <li>  [SQLITE_OPEN_TRANSIENT_DB]
+** <li>  [SQLITE_OPEN_SUBJOURNAL]
+** <li>  [SQLITE_OPEN_SUPER_JOURNAL]
+** <li>  [SQLITE_OPEN_WAL]
+** </ul>)^
+**
+** The file I/O implementation can use the object type flags to
+** change the way it deals with files.  For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op.  Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR.  Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen.  The xOpen method does not have to
+** allocate the structure; it should just fill it in.  Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
+** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
+** flag is never actually used and is not implemented in the built-in
+** VFSes of SQLite.  The file is named by the second argument and can be a
+** directory. The xAccess method returns [SQLITE_OK] on success or some
+** non-zero error code if there is an I/O error or if the name of
+** the file given in the second argument is illegal.  If SQLITE_OK
+** is returned, then non-zero or zero is written into *pResOut to indicate
+** whether or not the file is accessible.
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname.  The exact size of the output buffer
+** is also passed as a parameter to both  methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut.  The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given.  ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in
+** a 24-hour day).
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core.  These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce.  The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next.  Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next.  Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+** These routines are designed to aid in process initialization and
+** shutdown on embedded systems.  Workstation applications using
+** SQLite normally do not need to invoke either of these routines.
+**
+** A call to sqlite3_initialize() is an "effective" call if it is
+** the first time sqlite3_initialize() is invoked during the lifetime of
+** the process, or if it is the first time sqlite3_initialize() is invoked
+** following a call to sqlite3_shutdown().  ^(Only an effective call
+** of sqlite3_initialize() does any initialization.  All other calls
+** are harmless no-ops.)^
+**
+** A call to sqlite3_shutdown() is an "effective" call if it is the first
+** call to sqlite3_shutdown() since the last sqlite3_initialize().  ^(Only
+** an effective call to sqlite3_shutdown() does any deinitialization.
+** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
+**
+** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
+** is not.  The sqlite3_shutdown() interface must only be called from a
+** single thread.  All open [database connections] must be closed and all
+** other SQLite resources must be deallocated prior to invoking
+** sqlite3_shutdown().
+**
+** Among other things, ^sqlite3_initialize() will invoke
+** sqlite3_os_init().  Similarly, ^sqlite3_shutdown()
+** will invoke sqlite3_os_end().
+**
+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** ^If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically
+** initialized when [sqlite3_open()] is called if it has not be initialized
+** already.  ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
+** compile-time option, then the automatic calls to sqlite3_initialize()
+** are omitted and the application must call sqlite3_initialize() directly
+** prior to using any other SQLite interface.  For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface.  Future releases
+** of SQLite may require this.  In other words, the behavior exhibited
+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific
+** initialization of the SQLite library.  The sqlite3_os_end()
+** routine undoes the effect of sqlite3_os_init().  Typical tasks
+** performed by these routines include allocation or deallocation
+** of static resources, initialization of global variables,
+** setting up a default [sqlite3_vfs] module, or setting up
+** a default configuration using [sqlite3_config()].
+**
+** The application should never invoke either sqlite3_os_init()
+** or sqlite3_os_end() directly.  The application should only invoke
+** sqlite3_initialize() and sqlite3_shutdown().  The sqlite3_os_init()
+** interface is called automatically by sqlite3_initialize() and

+** An instance of this object defines the interface between SQLite

+**
+** This object is used in only one place in the SQLite interface.
+** A pointer to an instance of this object is the argument to
+** [sqlite3_config()] when the configuration option is
+** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
+** By creating an instance of this object
+** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
+** during configuration, an application can specify an alternative
+** memory allocation subsystem for SQLite to use for all of its
+** dynamic memory needs.
+**
+** Note that SQLite comes with several [built-in memory allocators]
+** that are perfectly adequate for the overwhelming majority of applications
+** and that this object is only useful to a tiny minority of applications
+** with specialized memory allocation requirements.  This object is
+** also used during testing of SQLite in order to specify an alternative
+** memory allocator that simulates memory out-of-memory conditions in
+** order to verify that SQLite recovers gracefully from such
+** conditions.
+**
+** The xMalloc, xRealloc, and xFree methods must work like the
+** malloc(), realloc() and free() functions from the standard C library.
+** ^SQLite guarantees that the second argument to
+** xRealloc is always a value returned by a prior call to xRoundup.
+**
+** xSize should return the allocated size of a memory allocation
+** previously obtained from xMalloc or xRealloc.  The allocated size
+** is always at least as big as the requested size but may be larger.
+**
+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size.  Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8.  Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0,
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator.  For example,
+** it might allocate any required mutexes or initialize internal data
+** structures.  The xShutdown method is invoked (indirectly) by
+** [sqlite3_shutdown()] and should deallocate any resources acquired
+** by xInit.  The pAppData pointer is used as the only parameter to
+** xInit and xShutdown.
+**
+** SQLite holds the [SQLITE_MUTEX_STATIC_MAIN] mutex when it invokes
+** the xInit method, so the xInit method need not be threadsafe.  The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  For all other methods, SQLite
+** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
+** [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
+** it is by default) and so the methods are automatically serialized.
+** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other
+** methods must be threadsafe or else make their own arrangements for
+** serialization.

+** on database connection D. ^Inserts into [WITHOUT ROWID] tables are not
+** recorded. ^If no successful [INSERT]s into rowid tables have ever occurred

+** ^(If an [INSERT] occurs within a trigger then this routine will

+**
+** ^The first argument to the busy handler is a copy of the void* pointer which

+** CAPI3REF: Convenience Routines For Running Queries
+** METHOD: sqlite3
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface.  A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns.  But
+** these numbers are not part of the result table itself.  These
+** numbers are obtained separately.  Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array.  The first M pointers point
+** to zero-terminated strings that  contain the names of the columns.
+** The remaining entries all point to query results.  NULL values result
+** in NULL pointers.  All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+**        Name        | Age
+**        -----------------------
+**        Alice       | 43
+**        Bob         | 28
+**        Cindy       | 21
+** </pre></blockquote>
+**
+** There are two columns (M==2) and three rows (N==3).  Thus the
+** result table has 8 entries.  Suppose the result table is stored
+** in an array named azResult.  Then azResult holds this content:
+**
+** <blockquote><pre>
+**        azResult&#91;0] = "Name";
+**        azResult&#91;1] = "Age";
+**        azResult&#91;2] = "Alice";
+**        azResult&#91;3] = "43";
+**        azResult&#91;4] = "Bob";
+**        azResult&#91;5] = "28";
+**        azResult&#91;6] = "Cindy";
+**        azResult&#91;7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**

+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly.  Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around
+** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite.  It uses only the public

+** specific action but allow the SQL statement to continue to be
+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be

+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
+** then the [sqlite3_prepare_v2()] or equivalent call that triggered

+** When the callback returns [SQLITE_OK], that means the operation

+** access is denied.
+**
+** ^The first parameter to the authorizer callback is a copy of the third
+** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. ^The third through sixth parameters
+** to the callback are either NULL pointers or zero-terminated strings
+** that contain additional details about the action to be authorized.
+** Applications must always be prepared to encounter a NULL pointer in any
+** of the third through the sixth parameters of the authorization callback.
+**
+** ^If the action code is [SQLITE_READ]

+** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
+** return can be used to deny an untrusted user access to individual
+** columns of a table.
+** ^When a table is referenced by a [SELECT] but no column values are

+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources

+**
+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument
+** begins with "file:", then the filename is interpreted as a URI. ^URI
+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the third argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default.  See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string
+** "localhost". ^If the authority is not an empty string or "localhost", an
+** error is returned to the caller. ^The fragment component of a URI, if
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character,
+** then it is interpreted as an absolute path. ^If the path does not begin
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path.
+** ^(On windows, the first component of an absolute path
+** is a drive specification (e.g. "C:").)^
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite and its built-in [VFSes] interpret the
+** following query parameters:
+**
+** <ul>
+**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+**     a VFS object that provides the operating system interface that should
+**     be used to access the database file on disk. ^If this option is set to
+**     an empty string the default VFS object is used. ^Specifying an unknown
+**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+**     present, then the VFS specified by the option takes precedence over
+**     the value passed as the fourth parameter to sqlite3_open_v2().
+**
+**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+**     "rwc", or "memory". Attempting to set it to any other value is
+**     an error)^.
+**     ^If "ro" is specified, then the database is opened for read-only
+**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
+**     third argument to sqlite3_open_v2(). ^If the mode option is set to
+**     "rw", then the database is opened for read-write (but not create)
+**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
+**     been set. ^Value "rwc" is equivalent to setting both
+**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
+**     set to "memory" then a pure [in-memory database] that never reads
+**     or writes from disk is used. ^It is an error to specify a value for
+**     the mode parameter that is less restrictive than that specified by
+**     the flags passed in the third parameter to sqlite3_open_v2().
+**
+**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+**     "private". ^Setting it to "shared" is equivalent to setting the
+**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is
+**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+**     a URI filename, its value overrides any behavior requested by setting
+**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+**
+**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
+**     [powersafe overwrite] property does or does not apply to the
+**     storage media on which the database file resides.
+**
+**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
+**     which if set disables file locking in rollback journal modes.  This
+**     is useful for accessing a database on a filesystem that does not
+**     support locking.  Caution:  Database corruption might result if two
+**     or more processes write to the same database and any one of those
+**     processes uses nolock=1.
+**
+**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
+**     parameter that indicates that the database file is stored on
+**     read-only media.  ^When immutable is set, SQLite assumes that the
+**     database file cannot be changed, even by a process with higher
+**     privilege, and so the database is opened read-only and all locking
+**     and change detection is disabled.  Caution: Setting the immutable
+**     property on a database file that does in fact change can result
+**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
+**     See also: [SQLITE_IOCAP_IMMUTABLE].
+**
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error.  Future versions of SQLite might understand additional query
+** parameters.  See "[query parameters with special meaning to SQLite]" for
+** additional information.

+** CAPI3REF: Obtain Values For URI Parameters
+**
+** These are utility routines, useful to [VFS|custom VFS implementations],
+** that check if a database file was a URI that contained a specific query
+** parameter, and if so obtains the value of that query parameter.
+**
+** The first parameter to these interfaces (hereafter referred to
+** as F) must be one of:
+** <ul>
+** <li> A database filename pointer created by the SQLite core and
+** passed into the xOpen() method of a VFS implemention, or
+** <li> A filename obtained from [sqlite3_db_filename()], or
+** <li> A new filename constructed using [sqlite3_create_filename()].
+** </ul>
+** If the F parameter is not one of the above, then the behavior is
+** undefined and probably undesirable.  Older versions of SQLite were
+** more tolerant of invalid F parameters than newer versions.
+**
+** If F is a suitable filename (as described in the previous paragraph)
+** and if P is the name of the query parameter, then
+** sqlite3_uri_parameter(F,P) returns the value of the P
+** parameter if it exists or a NULL pointer if P does not appear as a
+** query parameter on F.  If P is a query parameter of F and it
+** has no explicit value, then sqlite3_uri_parameter(F,P) returns
+** a pointer to an empty string.
+**
+** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
+** parameter and returns true (1) or false (0) according to the value
+** of P.  The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
+** value of query parameter P is one of "yes", "true", or "on" in any
+** case or if the value begins with a non-zero number.  The
+** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
+** query parameter P is one of "no", "false", or "off" in any case or
+** if the value begins with a numeric zero.  If P is not a query
+** parameter on F or if the value of P does not match any of the
+** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
+**
+** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
+** 64-bit signed integer and returns that integer, or D if P does not
+** exist.  If the value of P is something other than an integer, then
+** zero is returned.
+**
+** The sqlite3_uri_key(F,N) returns a pointer to the name (not
+** the value) of the N-th query parameter for filename F, or a NULL
+** pointer if N is less than zero or greater than the number of query
+** parameters minus 1.  The N value is zero-based so N should be 0 to obtain
+** the name of the first query parameter, 1 for the second parameter, and
+** so forth.
+**
+** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
+** sqlite3_uri_boolean(F,P,B) returns B.  If F is not a NULL pointer and
+** is not a database file pathname pointer that the SQLite core passed
+** into the xOpen VFS method, then the behavior of this routine is undefined
+** and probably undesirable.
+**
+** Beginning with SQLite [version 3.31.0] ([dateof:3.31.0]) the input F
+** parameter can also be the name of a rollback journal file or WAL file
+** in addition to the main database file.  Prior to version 3.31.0, these
+** routines would only work if F was the name of the main database file.
+** When the F parameter is the name of the rollback journal or WAL file,
+** it has access to all the same query parameters as were found on the

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+** METHOD: sqlite3
+** CONSTRUCTOR: sqlite3_stmt
+**
+** To execute an SQL statement, it must first be compiled into a byte-code
+** program using one of these routines.  Or, in other words, these routines
+** are constructors for the [prepared statement] object.
+**
+** The preferred routine to use is [sqlite3_prepare_v2()].  The
+** [sqlite3_prepare()] interface is legacy and should be avoided.
+** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
+** for special purposes.
+**
+** The use of the UTF-8 interfaces is preferred, as SQLite currently
+** does all parsing using UTF-8.  The UTF-16 interfaces are provided
+** as a convenience.  The UTF-16 interfaces work by converting the
+** input text into UTF-8, then invoking the corresponding UTF-8 interface.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()].  The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
+** and sqlite3_prepare_v3()
+** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() use UTF-16.
+**
+** ^If the nByte argument is negative, then zSql is read up to the
+** first zero terminator. ^If nByte is positive, then it is the
+** number of bytes read from zSql.  ^If nByte is zero, then no prepared
+** statement is generated.
+** If the caller knows that the supplied string is nul-terminated, then
+** there is a small performance advantage to passing an nByte parameter that
+** is the number of bytes in the input string <i>including</i>
+** the nul-terminator.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql.  These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
+** to NULL.  ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];

+**
+** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),

+** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
+** are retained for backwards compatibility, but their use is discouraged.
+** ^In the "vX" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>
+**
+** <li>
+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes].  ^The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and the application would have to make a second call to [sqlite3_reset()]
+** in order to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.
+** </li>
+**
+** <li>
+** ^If the specific value bound to a [parameter | host parameter] in the
+** WHERE clause might influence the choice of query plan for a statement,
+** then the statement will be automatically recompiled, as if there had been
+** a schema change, on the first [sqlite3_step()] call following any change
+** to the [sqlite3_bind_text | bindings] of that [parameter].
+** ^The specific value of a WHERE-clause [parameter] might influence the
+** choice of query plan if the parameter is the left-hand side of a [LIKE]
+** or [GLOB] operator or if the parameter is compared to an indexed column
+** and the [SQLITE_ENABLE_STAT4] compile-time option is enabled.
+** </li>
+** </ol>
+**
+** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
+** the extra prepFlags parameter, which is a bit array consisting of zero or
+** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags.  ^The

+** ^With the "v2" interface, any of the other [result codes] or
+** [extended result codes] might be returned as well.

+** or occurs outside of an explicit transaction, then you can retry the
+** statement.  If the statement is not a [COMMIT] and occurs within an
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** ^[SQLITE_DONE] means that the statement has finished executing
+** successfully.  sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred.  sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** ^With the legacy interface, a more specific error code (for example,

+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement].  ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
+** be the case that the same database connection is being used by two or
+** more threads at the same moment in time.

+** other than [SQLITE_ROW] before any subsequent invocation of
+** sqlite3_step().  Failure to reset the prepared statement using
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
+** sqlite3_step().  But after [version 3.6.23.1] ([dateof:3.6.23.1],
+** sqlite3_step() began
+** calling [sqlite3_reset()] automatically in this circumstance rather

+**
+** ^These routines return information about a single column of the current
+** result row of a query.  ^In every case the first argument is a pointer
+** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
+** that was returned from [sqlite3_prepare_v2()] or one of its variants)
+** and the second argument is the index of the column for which information
+** should be returned. ^The leftmost column of the result set has the index 0.
+** ^The number of columns in the result can be determined using
+** [sqlite3_column_count()].
+**
+** If the SQL statement does not currently point to a valid row, or if the
+** column index is out of range, the result is undefined.
+** These routines may only be called when the most recent call to
+** [sqlite3_step()] has returned [SQLITE_ROW] and neither
+** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
+** If any of these routines are called after [sqlite3_reset()] or
+** [sqlite3_finalize()] or after [sqlite3_step()] has returned
+** something other than [SQLITE_ROW], the results are undefined.
+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
+** are called from a different thread while any of these routines
+** are pending, then the results are undefined.
+**
+** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
+** each return the value of a result column in a specific data format.  If
+** the result column is not initially in the requested format (for example,
+** if the query returns an integer but the sqlite3_column_text() interface
+** is used to extract the value) then an automatic type conversion is performed.
+**
+** ^The sqlite3_column_type() routine returns the
+** [SQLITE_INTEGER | datatype code] for the initial data type
+** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
+** The return value of sqlite3_column_type() can be used to decide which
+** of the first six interface should be used to extract the column value.
+** The value returned by sqlite3_column_type() is only meaningful if no
+** automatic type conversions have occurred for the value in question.
+** After a type conversion, the result of calling sqlite3_column_type()
+** is undefined, though harmless.  Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
+** or sqlite3_column_bytes16() interfaces can be used to determine the size
+** of that BLOB or string.
+**
+** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
+** the string to UTF-8 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
+**
+** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
+** the string to UTF-16 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes16() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
+**
+** ^The values returned by [sqlite3_column_bytes()] and
+** [sqlite3_column_bytes16()] do not include the zero terminators at the end
+** of the string.  ^For clarity: the values returned by
+** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
+** bytes in the string, not the number of characters.
+**
+** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even empty strings, are always zero-terminated.  ^The return
+** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
+**
+** ^Strings returned by sqlite3_column_text16() always have the endianness
+** which is native to the platform, regardless of the text encoding set
+** for the database.
+**
+** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object.  In a multithreaded environment,
+** an unprotected sqlite3_value object may only be used safely with
+** [sqlite3_bind_value()] and [sqlite3_result_value()].
+** If the [unprotected sqlite3_value] object returned by
+** [sqlite3_column_value()] is used in any other way, including calls
+** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
+** or [sqlite3_value_bytes()], the behavior is not threadsafe.
+** Hence, the sqlite3_column_value() interface
+** is normally only useful within the implementation of
+** [application-defined SQL functions] or [virtual tables], not within
+** top-level application code.
+**
+** These routines may attempt to convert the datatype of the result.
+** ^For example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to perform the
+** conversion automatically.  ^(The following table details the conversions
+** that are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
+**
+** <tr><td>  NULL    <td> INTEGER   <td> Result is 0

+** <tr><td>  NULL    <td>   TEXT    <td> Result is a NULL pointer
+** <tr><td>  NULL    <td>   BLOB    <td> Result is a NULL pointer

+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+**      sqlite3_column_text16() is called.  A zero-terminator might
+**      need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+**      sqlite3_column_text16() is called.  The content must be converted
+**      to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+**      sqlite3_column_text() is called.  The content must be converted
+**      to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified.  Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** ^The pointers returned are valid until a type conversion occurs as
+** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
+** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
+** and BLOBs is freed automatically.  Do not pass the pointers returned
+** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** As long as the input parameters are correct, these routines will only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_column_blob()
+** <li> sqlite3_column_text()
+** <li> sqlite3_column_text16()
+** <li> sqlite3_column_bytes()
+** <li> sqlite3_column_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+**
+** ^These functions (collectively known as "function creation routines")
+** are used to add SQL functions or aggregates or to redefine the behavior
+** of existing SQL functions or aggregates. The only differences between
+** the three "sqlite3_create_function*" routines are the text encoding

+** created) and the presence or absence of a destructor callback for
+** the application data pointer. Function sqlite3_create_window_function()
+** is similar, but allows the user to supply the extra callback functions
+** needed by [aggregate window functions].
+**
+** ^The first parameter is the [database connection] to which the SQL
+** function is to be added.  ^If an application uses more than one database
+** connection then application-defined SQL functions must be added
+** to each database connection separately.
+**
+** ^The second parameter is the name of the SQL function to be created or
+** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
+** representation, exclusive of the zero-terminator.  ^Note that the name
+** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.
+** ^Any attempt to create a function with a longer name
+** will result in [SQLITE_MISUSE] being returned.
+**
+** ^The third parameter (nArg)
+** is the number of arguments that the SQL function or
+** aggregate takes. ^If this parameter is -1, then the SQL function or
+** aggregate may take any number of arguments between 0 and the limit
+** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
+** parameter is less than -1 or greater than 127 then the behavior is
+** undefined.
+**
+** ^The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters.  The application should set this parameter to
+** [SQLITE_UTF16LE] if the function implementation invokes
+** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
+** implementation invokes [sqlite3_value_text16be()] on an input, or
+** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
+** otherwise.  ^The same SQL function may be registered multiple times using
+** different preferred text encodings, with different implementations for
+** each encoding.
+** ^When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+**
+** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
+** to signal that the function will always return the same result given
+** the same inputs within a single SQL statement.  Most SQL functions are
+** deterministic.  The built-in [random()] SQL function is an example of a
+** function that is not deterministic.  The SQLite query planner is able to
+** perform additional optimizations on deterministic functions, so use
+** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
+**
+** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
+** flag, which if present prevents the function from being invoked from
+** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
+** index expressions, or the WHERE clause of partial indexes.
+**
+** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
+** all application-defined SQL functions that do not need to be
+** used inside of triggers, view, CHECK constraints, or other elements of
+** the database schema.  This flags is especially recommended for SQL
+** functions that have side effects or reveal internal application state.
+** Without this flag, an attacker might be able to modify the schema of
+** a database file to include invocations of the function with parameters
+** chosen by the attacker, which the application will then execute when
+** the database file is opened and read.
+**
+** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
+** function can gain access to this pointer using [sqlite3_user_data()].)^
+**
+** ^The sixth, seventh and eighth parameters passed to the three
+** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
+** pointers to C-language functions that implement the SQL function or
+** aggregate. ^A scalar SQL function requires an implementation of the xFunc
+** callback only; NULL pointers must be passed as the xStep and xFinal
+** parameters. ^An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
+** SQL function or aggregate, pass NULL pointers for all three function
+** callbacks.
+**
+** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue
+** and xInverse) passed to sqlite3_create_window_function are pointers to
+** C-language callbacks that implement the new function. xStep and xFinal
+** must both be non-NULL. xValue and xInverse may either both be NULL, in
+** which case a regular aggregate function is created, or must both be
+** non-NULL, in which case the new function may be used as either an aggregate
+** or aggregate window function. More details regarding the implementation
+** of aggregate window functions are
+** [user-defined window functions|available here].
+**
+** ^(If the final parameter to sqlite3_create_function_v2() or
+** sqlite3_create_window_function() is not NULL, then it is destructor for
+** the application data pointer. The destructor is invoked when the function
+** is deleted, either by being overloaded or when the database connection
+** closes.)^ ^The destructor is also invoked if the call to
+** sqlite3_create_function_v2() fails.  ^When the destructor callback is
+** invoked, it is passed a single argument which is a copy of the application
+** data pointer which was the fifth parameter to sqlite3_create_function_v2().
+**
+** ^It is permitted to register multiple implementations of the same
+** functions with the same name but with either differing numbers of
+** arguments or differing preferred text encodings.  ^SQLite will use
+** the implementation that most closely matches the way in which the
+** SQL function is used.  ^A function implementation with a non-negative
+** nArg parameter is a better match than a function implementation with
+** a negative nArg.  ^A function where the preferred text encoding
+** matches the database encoding is a better
+** match than a function where the encoding is different.
+** ^A function where the encoding difference is between UTF16le and UTF16be
+** is a closer match than a function where the encoding difference is
+** between UTF8 and UTF16.
+**
+** ^Built-in functions may be overloaded by new application-defined functions.
+**
+** ^An application-defined function is permitted to call other

+**
+** <b>Details:</b>
+**
+** These routines extract type, size, and content information from
+** [protected sqlite3_value] objects.  Protected sqlite3_value objects
+** are used to pass parameter information into the functions that
+** implement [application-defined SQL functions] and [virtual tables].
+**
+** These routines work only with [protected sqlite3_value] objects.
+** Any attempt to use these routines on an [unprotected sqlite3_value]
+** is not threadsafe.
+**
+** ^These routines work just like the corresponding [column access functions]
+** except that these routines take a single [protected sqlite3_value] object
+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
+**
+** ^The sqlite3_value_text16() interface extracts a UTF-16 string
+** in the native byte-order of the host machine.  ^The
+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+** extract UTF-16 strings as big-endian and little-endian respectively.
+**
+** ^If [sqlite3_value] object V was initialized
+** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
+** and if X and Y are strings that compare equal according to strcmp(X,Y),
+** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
+** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer()
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^(The sqlite3_value_type(V) interface returns the
+** [SQLITE_INTEGER | datatype code] for the initial datatype of the
+** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
+** Other interfaces might change the datatype for an sqlite3_value object.
+** For example, if the datatype is initially SQLITE_INTEGER and
+** sqlite3_value_text(V) is called to extract a text value for that
+** integer, then subsequent calls to sqlite3_value_type(V) might return
+** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
+** occurs is undefined and may change from one release of SQLite to the next.
+**
+** ^(The sqlite3_value_numeric_type() interface attempts to apply
+** numeric affinity to the value.  This means that an attempt is
+** made to convert the value to an integer or floating point.  If
+** such a conversion is possible without loss of information (in other
+** words, if the value is a string that looks like a number)
+** then the conversion is performed.  Otherwise no conversion occurs.
+** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
+**
+** ^Within the [xUpdate] method of a [virtual table], the
+** sqlite3_value_nochange(X) interface returns true if and only if
+** the column corresponding to X is unchanged by the UPDATE operation
+** that the xUpdate method call was invoked to implement and if
+** and the prior [xColumn] method call that was invoked to extracted
+** the value for that column returned without setting a result (probably
+** because it queried [sqlite3_vtab_nochange()] and found that the column
+** was unchanging).  ^Within an [xUpdate] method, any value for which
+** sqlite3_value_nochange(X) is true will in all other respects appear
+** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
+** than within an [xUpdate] method call for an UPDATE statement, then
+** the return value is arbitrary and meaningless.
+**
+** ^The sqlite3_value_frombind(X) interface returns non-zero if the
+** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
+** interfaces.  ^If X comes from an SQL literal value, or a table column,
+** or an expression, then sqlite3_value_frombind(X) returns zero.
+**
+** Please pay particular attention to the fact that the pointer returned
+** from [sqlite3_value_blob()], [sqlite3_value_text()], or
+** [sqlite3_value_text16()] can be invalidated by a subsequent call to
+** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
+** or [sqlite3_value_text16()].
+**
+** These routines must be called from the same thread as
+** the SQL function that supplied the [sqlite3_value*] parameters.
+**
+** As long as the input parameter is correct, these routines can only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_value_blob()
+** <li> sqlite3_value_text()
+** <li> sqlite3_value_text16()
+** <li> sqlite3_value_text16le()
+** <li> sqlite3_value_text16be()
+** <li> sqlite3_value_bytes()
+** <li> sqlite3_value_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** Refer to the [SQL parameter] documentation for additional information.
+**
+** ^The sqlite3_result_blob() interface sets the result from
+** an application-defined function to be the BLOB whose content is pointed

+** third parameter.
+**
+** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
+** interfaces set the result of the application-defined function to be
+** a BLOB containing all zero bytes and N bytes in size.
+**
+** ^The sqlite3_result_double() interface sets the result from
+** an application-defined function to be a floating point value specified
+** by its 2nd argument.
+**
+** ^The sqlite3_result_error() and sqlite3_result_error16() functions
+** cause the implemented SQL function to throw an exception.
+** ^SQLite uses the string pointed to by the
+** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
+** as the text of an error message.  ^SQLite interprets the error
+** message string from sqlite3_result_error() as UTF-8. ^SQLite
+** interprets the string from sqlite3_result_error16() as UTF-16 using
+** the same [byte-order determination rules] as [sqlite3_bind_text16()].
+** ^If the third parameter to sqlite3_result_error()
+** or sqlite3_result_error16() is negative then SQLite takes as the error
+** message all text up through the first zero character.
+** ^If the third parameter to sqlite3_result_error() or
+** sqlite3_result_error16() is non-negative then SQLite takes that many
+** bytes (not characters) from the 2nd parameter as the error message.
+** ^The sqlite3_result_error() and sqlite3_result_error16()
+** routines make a private copy of the error message text before
+** they return.  Hence, the calling function can deallocate or
+** modify the text after they return without harm.
+** ^The sqlite3_result_error_code() function changes the error code
+** returned by SQLite as a result of an error in a function.  ^By default,
+** the error code is SQLITE_ERROR.  ^A subsequent call to sqlite3_result_error()
+** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
+**
+** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
+** error indicating that a string or BLOB is too long to represent.
+**
+** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
+** error indicating that a memory allocation failed.
+**
+** ^The sqlite3_result_int() interface sets the return value
+** of the application-defined function to be the 32-bit signed integer
+** value given in the 2nd argument.
+** ^The sqlite3_result_int64() interface sets the return value
+** of the application-defined function to be the 64-bit signed integer
+** value given in the 2nd argument.
+**
+** ^The sqlite3_result_null() interface sets the return value
+** of the application-defined function to be NULL.
+**
+** ^The sqlite3_result_text(), sqlite3_result_text16(),
+** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
+** set the return value of the application-defined function to be
+** a text string which is represented as UTF-8, UTF-16 native byte order,
+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** ^The sqlite3_result_text64() interface sets the return value of an
+** application-defined function to be a text string in an encoding
+** specified by the fifth (and last) parameter, which must be one
+** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
+** ^SQLite takes the text result from the application from
+** the 2nd parameter of the sqlite3_result_text* interfaces.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is negative, then SQLite takes result text from the 2nd parameter
+** through the first zero character.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined
+** function result.  If the 3rd parameter is non-negative, then it
+** must be the byte offset into the string where the NUL terminator would
+** appear if the string where NUL terminated.  If any NUL characters occur
+** in the string at a byte offset that is less than the value of the 3rd
+** parameter, then the resulting string will contain embedded NULs and the
+** result of expressions operating on strings with embedded NULs is undefined.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
+** function as the destructor on the text or BLOB result when it has
+** finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
+** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
+** assumes that the text or BLOB result is in constant space and does not
+** copy the content of the parameter nor call a destructor on the content
+** when it has finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
+** then SQLite makes a copy of the result into space obtained
+** from [sqlite3_malloc()] before it returns.
+**
+** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
+** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
+** when the encoding is not UTF8, if the input UTF16 begins with a
+** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
+** string and the rest of the string is interpreted according to the
+** byte-order specified by the BOM.  ^The byte-order specified by
+** the BOM at the beginning of the text overrides the byte-order
+** specified by the interface procedure.  ^So, for example, if
+** sqlite3_result_text16le() is invoked with text that begins
+** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
+** first two bytes of input are skipped and the remaining input
+** is interpreted as UTF16BE text.
+**
+** ^For UTF16 input text to the sqlite3_result_text16(),
+** sqlite3_result_text16be(), sqlite3_result_text16le(), and
+** sqlite3_result_text64() routines, if the text contains invalid
+** UTF16 characters, the invalid characters might be converted
+** into the unicode replacement character, U+FFFD.
+**
+** ^The sqlite3_result_value() interface sets the result of
+** the application-defined function to be a copy of the
+** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
+** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
+** so that the [sqlite3_value] specified in the parameter may change or
+** be deallocated after sqlite3_result_value() returns without harm.
+** ^A [protected sqlite3_value] object may always be used where an
+** [unprotected sqlite3_value] object is required, so either
+** kind of [sqlite3_value] object can be used with this interface.
+**
+** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
+** SQL NULL value, just like [sqlite3_result_null(C)], except that it

+** NULL value such that the pointer can be retrieved within an

+**
+** The sqlite3_index_info structure and its substructures is used as part
+** of the [virtual table] interface to
+** pass information into and receive the reply from the [xBestIndex]
+** method of a [virtual table module].  The fields under **Inputs** are the
+** inputs to xBestIndex and are read-only.  xBestIndex inserts its
+** results into the **Outputs** fields.
+**
+** ^(The aConstraint[] array records WHERE clause constraints of the form:
+**
+** <blockquote>column OP expr</blockquote>
+**
+** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
+** stored in aConstraint[].op using one of the
+** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
+** ^(The index of the column is stored in
+** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
+** expr on the right-hand side can be evaluated (and thus the constraint
+** is usable) and false if it cannot.)^
+**
+** ^The optimizer automatically inverts terms of the form "expr OP column"
+** and makes other simplifications to the WHERE clause in an attempt to
+** get as many WHERE clause terms into the form shown above as possible.
+** ^The aConstraint[] array only reports WHERE clause terms that are
+** relevant to the particular virtual table being queried.
+**
+** ^Information about the ORDER BY clause is stored in aOrderBy[].
+** ^Each term of aOrderBy records a column of the ORDER BY clause.
+**
+** The colUsed field indicates which columns of the virtual table may be
+** required by the current scan. Virtual table columns are numbered from
+** zero in the order in which they appear within the CREATE TABLE statement
+** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
+** the corresponding bit is set within the colUsed mask if the column may be
+** required by SQLite. If the table has at least 64 columns and any column
+** to the right of the first 63 is required, then bit 63 of colUsed is also
+** set. In other words, column iCol may be required if the expression
+** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
+** non-zero.
+**
+** The [xBestIndex] method must fill aConstraintUsage[] with information
+** about what parameters to pass to xFilter.  ^If argvIndex>0 then
+** the right-hand side of the corresponding aConstraint[] is evaluated
+** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
+** is true, then the constraint is assumed to be fully handled by the
+** virtual table and might not be checked again by the byte code.)^ ^(The
+** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
+** is left in its default setting of false, the constraint will always be
+** checked separately in byte code.  If the omit flag is change to true, then
+** the constraint may or may not be checked in byte code.  In other words,
+** when the omit flag is true there is no guarantee that the constraint will
+** not be checked again using byte code.)^
+**
+** ^The idxNum and idxPtr values are recorded and passed into the
+** [xFilter] method.
+** ^[sqlite3_free()] is used to free idxPtr if and only if
+** needToFreeIdxPtr is true.
+**
+** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
+** the correct order to satisfy the ORDER BY clause so that no separate
+** sorting step is required.
+**
+** ^The estimatedCost value is an estimate of the cost of a particular
+** strategy. A cost of N indicates that the cost of the strategy is similar
+** to a linear scan of an SQLite table with N rows. A cost of log(N)
+** indicates that the expense of the operation is similar to that of a
+** binary search on a unique indexed field of an SQLite table with N rows.
+**
+** ^The estimatedRows value is an estimate of the number of rows that
+** will be returned by the strategy.
+**
+** The xBestIndex method may optionally populate the idxFlags field with a
+** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+** assumes that the strategy may visit at most one row.
+**
+** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+** SQLite also assumes that if a call to the xUpdate() method is made as
+** part of the same statement to delete or update a virtual table row and the
+** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+** any database changes. In other words, if the xUpdate() returns
+** SQLITE_CONSTRAINT, the database contents must be exactly as they were
+** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+** the xUpdate method are automatically rolled back by SQLite.
+**
+** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
+** structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
+** If a virtual table extension is
+** used with an SQLite version earlier than 3.8.2, the results of attempting
+** to read or write the estimatedRows field are undefined (but are likely
+** to include crashing the application). The estimatedRows field should
+** therefore only be used if [sqlite3_libversion_number()] returns a
+** value greater than or equal to 3008002. Similarly, the idxFlags field
+** was added for [version 3.9.0] ([dateof:3.9.0]).

+** ^The xMutexEnd method defined by this structure is invoked as
+** part of system shutdown by the sqlite3_shutdown() function. The
+** implementation of this method is expected to release all outstanding
+** resources obtained by the mutex methods implementation, especially
+** those obtained by the xMutexInit method.  ^The xMutexEnd()
+** interface is invoked exactly once for each call to [sqlite3_shutdown()].

+** CAPI3REF: SQL Keyword Checking
+**
+** These routines provide access to the set of SQL language keywords
+** recognized by SQLite.  Applications can uses these routines to determine
+** whether or not a specific identifier needs to be escaped (for example,
+** by enclosing in double-quotes) so as not to confuse the parser.
+**
+** The sqlite3_keyword_count() interface returns the number of distinct
+** keywords understood by SQLite.
+**
+** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
+** makes *Z point to that keyword expressed as UTF8 and writes the number
+** of bytes in the keyword into *L.  The string that *Z points to is not
+** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
+** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
+** or L are NULL or invalid pointers then calls to
+** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
+**
+** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
+** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
+** if it is and zero if not.
+**
+** The parser used by SQLite is forgiving.  It is often possible to use
+** a keyword as an identifier as long as such use does not result in a
+** parsing ambiguity.  For example, the statement
+** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
+** creates a new table named "BEGIN" with three columns named
+** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
+** using keywords as identifiers.  Common techniques used to avoid keyword
+** name collisions include:
+** <ul>
+** <li> Put all identifier names inside double-quotes.  This is the official
+**      SQL way to escape identifier names.
+** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
+**      but it is what SQL Server does and so lots of programmers use this
+**      technique.
+** <li> Begin every identifier with the letter "Z" as no SQL keywords start
+**      with "Z".
+** <li> Include a digit somewhere in every identifier name.
+** </ul>
+**
+** Note that the number of keywords understood by SQLite can depend on
+** compile-time options.  For example, "VACUUM" is not a keyword if
+** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option.  Also,
+** new keywords may be added to future releases of SQLite.

+**
+** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
+** register an alternative page cache implementation by passing in an
+** instance of the sqlite3_pcache_methods2 structure.)^
+** In many applications, most of the heap memory allocated by
+** SQLite is used for the page cache.
+** By implementing a
+** custom page cache using this API, an application can better control
+** the amount of memory consumed by SQLite, the way in which
+** that memory is allocated and released, and the policies used to
+** determine exactly which parts of a database file are cached and for
+** how long.
+**
+** The alternative page cache mechanism is an
+** extreme measure that is only needed by the most demanding applications.
+** The built-in page cache is recommended for most uses.
+**
+** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config].  Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.)^
+**
+** [[the xInit() page cache method]]
+** ^(The xInit() method is called once for each effective
+** call to [sqlite3_initialize()])^
+** (usually only once during the lifetime of the process). ^(The xInit()
+** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
+** The intent of the xInit() method is to set up global data structures
+** required by the custom page cache implementation.
+** ^(If the xInit() method is NULL, then the
+** built-in default page cache is used instead of the application defined
+** page cache.)^
+**
+** [[the xShutdown() page cache method]]
+** ^The xShutdown() method is called by [sqlite3_shutdown()].
+** It can be used to clean up
+** any outstanding resources before process shutdown, if required.
+** ^The xShutdown() method may be NULL.
+**
+** ^SQLite automatically serializes calls to the xInit method,
+** so the xInit method need not be threadsafe.  ^The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  All other methods must be threadsafe
+** in multithreaded applications.
+**
+** ^SQLite will never invoke xInit() more than once without an intervening
+** call to xShutdown().
+**
+** [[the xCreate() page cache methods]]
+** ^SQLite invokes the xCreate() method to construct a new cache instance.
+** SQLite will typically create one cache instance for each open database file,
+** though this is not guaranteed. ^The
+** first parameter, szPage, is the size in bytes of the pages that must
+** be allocated by the cache.  ^szPage will always a power of two.  ^The
+** second parameter szExtra is a number of bytes of extra storage
+** associated with each page cache entry.  ^The szExtra parameter will
+** a number less than 250.  SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk.  The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+**
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a
+** single database page.  The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1.  After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact.  If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+**                 Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
+**                 NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^  In between the xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument.  If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single
+** call to xUnpin() unpins the page regardless of the number of prior calls
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible.  The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** CAPI3REF: Unlock Notification
+** METHOD: sqlite3
+**
+** ^When running in shared-cache mode, a database operation may fail with
+** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
+** individual tables within the shared-cache cannot be obtained. See
+** [SQLite Shared-Cache Mode] for a description of shared-cache locking.
+** ^This API may be used to register a callback that SQLite will invoke
+** when the connection currently holding the required lock relinquishes it.
+** ^This API is only available if the library was compiled with the
+** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
+**
+** See Also: [Using the SQLite Unlock Notification Feature].
+**
+** ^Shared-cache locks are released when a database connection concludes
+** its current transaction, either by committing it or rolling it back.
+**
+** ^When a connection (known as the blocked connection) fails to obtain a
+** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
+** identity of the database connection (the blocking connection) that
+** has locked the required resource is stored internally. ^After an
+** application receives an SQLITE_LOCKED error, it may call the
+** sqlite3_unlock_notify() method with the blocked connection handle as
+** the first argument to register for a callback that will be invoked
+** when the blocking connections current transaction is concluded. ^The
+** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
+** call that concludes the blocking connection's transaction.
+**
+** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
+** there is a chance that the blocking connection will have already
+** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
+** If this happens, then the specified callback is invoked immediately,
+** from within the call to sqlite3_unlock_notify().)^
+**
+** ^If the blocked connection is attempting to obtain a write-lock on a
+** shared-cache table, and more than one other connection currently holds
+** a read-lock on the same table, then SQLite arbitrarily selects one of
+** the other connections to use as the blocking connection.
+**
+** ^(There may be at most one unlock-notify callback registered by a
+** blocked connection. If sqlite3_unlock_notify() is called when the
+** blocked connection already has a registered unlock-notify callback,
+** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
+** called with a NULL pointer as its second argument, then any existing
+** unlock-notify callback is canceled. ^The blocked connections
+** unlock-notify callback may also be canceled by closing the blocked
+** connection using [sqlite3_close()].
+**
+** The unlock-notify callback is not reentrant. If an application invokes
+** any sqlite3_xxx API functions from within an unlock-notify callback, a
+** crash or deadlock may be the result.
+**
+** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
+** returns SQLITE_OK.
+**
+** <b>Callback Invocation Details</b>
+**
+** When an unlock-notify callback is registered, the application provides a
+** single void* pointer that is passed to the callback when it is invoked.
+** However, the signature of the callback function allows SQLite to pass
+** it an array of void* context pointers. The first argument passed to
+** an unlock-notify callback is a pointer to an array of void* pointers,
+** and the second is the number of entries in the array.
+**
+** When a blocking connection's transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just
+** SQLITE_LOCKED.)^

+** within the same xBestIndex call.  ^If the interface returns true
+** (non-zero), that means that the constraint is an IN operator
+** that can be processed all-at-once.  ^If the constraint is not an IN
+** operator or cannot be processed all-at-once, then the interface returns

+**  <pre>
+**  &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)
+**  </pre>
+**
+** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are
+** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes
+** are recorded for rows for which (idx IS NULL) is true. However, for such
+** rows a zero-length blob (SQL value X'') is stored in the changeset or
+** patchset instead of a NULL value. This allows such changesets to be
+** manipulated by legacy implementations of sqlite3changeset_invert(),
+** concat() and similar.
+**
+** The sqlite3changeset_apply() function automatically converts the
+** zero-length blob back to a NULL value when updating the sqlite_stat1
+** table. However, if the application calls sqlite3changeset_new(),
+** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset
+** iterator directly (including on a changeset iterator passed to a
+** conflict-handler callback) then the X'' value is returned. The application
+** must translate X'' to NULL itself if required.
+**
+** Legacy (older than 3.22.0) versions of the sessions module cannot capture
+** changes made to the sqlite_stat1 table. Legacy versions of the
+** sqlite3changeset_apply() function silently ignore any modifications to the
+** sqlite_stat1 table that are part of a changeset or patchset.

+** and *pnChangeset to the size of the changeset in bytes before returning
+** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
+** zero and return an SQLite error code.
+**
+** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
+** each representing a change to a single row of an attached table. An INSERT
+** change contains the values of each field of a new database row. A DELETE
+** contains the original values of each field of a deleted database row. An
+** UPDATE change contains the original values of each field of an updated
+** database row along with the updated values for each updated non-primary-key
+** column. It is not possible for an UPDATE change to represent a change that
+** modifies the values of primary key columns. If such a change is made, it
+** is represented in a changeset as a DELETE followed by an INSERT.
+**
+** Changes are not recorded for rows that have NULL values stored in one or
+** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+** no corresponding change is present in the changesets returned by this
+** function. If an existing row with one or more NULL values stored in
+** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+** only an INSERT is appears in the changeset. Similarly, if an existing row
+** with non-NULL PRIMARY KEY values is updated so that one or more of its
+** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+** DELETE change only.
+**
+** The contents of a changeset may be traversed using an iterator created
+** using the [sqlite3changeset_start()] API. A changeset may be applied to
+** a database with a compatible schema using the [sqlite3changeset_apply()]
+** API.
+**
+** Within a changeset generated by this function, all changes related to a
+** single table are grouped together. In other words, when iterating through
+** a changeset or when applying a changeset to a database, all changes related
+** to a single table are processed before moving on to the next table. Tables
+** are sorted in the same order in which they were attached (or auto-attached)
+** to the sqlite3_session object. The order in which the changes related to
+** a single table are stored is undefined.
+**
+** Following a successful call to this function, it is the responsibility of
+** the caller to eventually free the buffer that *ppChangeset points to using
+** [sqlite3_free()].
+**
+** <h3>Changeset Generation</h3>
+**
+** Once a table has been attached to a session object, the session object
+** records the primary key values of all new rows inserted into the table.
+** It also records the original primary key and other column values of any
+** deleted or updated rows. For each unique primary key value, data is only
+** recorded once - the first time a row with said primary key is inserted,
+** updated or deleted in the lifetime of the session.
+**
+** There is one exception to the previous paragraph: when a row is inserted,
+** updated or deleted, if one or more of its primary key columns contain a
+** NULL value, no record of the change is made.
+**
+** The session object therefore accumulates two types of records - those
+** that consist of primary key values only (created when the user inserts
+** a new record) and those that consist of the primary key values and the
+** original values of other table columns (created when the users deletes
+** or updates a record).
+**
+** When this function is called, the requested changeset is created using
+** both the accumulated records and the current contents of the database
+** file. Specifically:
+**
+** <ul>
+**   <li> For each record generated by an insert, the database is queried
+**        for a row with a matching primary key. If one is found, an INSERT
+**        change is added to the changeset. If no such row is found, no change
+**        is added to the changeset.
+**
+**   <li> For each record generated by an update or delete, the database is
+**        queried for a row with a matching primary key. If such a row is
+**        found and one or more of the non-primary key fields have been
+**        modified from their original values, an UPDATE change is added to
+**        the changeset. Or, if no such row is found in the table, a DELETE
+**        change is added to the changeset. If there is a row with a matching
+**        primary key in the database, but all fields contain their original
+**        values, no change is added to the changeset.
+** </ul>
+**
+** This means, amongst other things, that if a row is inserted and then later
+** deleted while a session object is active, neither the insert nor the delete
+** will be present in the changeset. Or if a row is deleted and then later a
+** row with the same primary key values inserted while a session object is
+** active, the resulting changeset will contain an UPDATE change instead of
+** a DELETE and an INSERT.
+**
+** When a session object is disabled (see the [sqlite3session_enable()] API),
+** it does not accumulate records when rows are inserted, updated or deleted.
+** This may appear to have some counter-intuitive effects if a single row
+** is written to more than once during a session. For example, if a row
+** is inserted while a session object is enabled, then later deleted while
+** the same session object is disabled, no INSERT record will appear in the
+** changeset, even though the delete took place while the session was disabled.
+** Or, if one field of a row is updated while a session is disabled, and
+** another field of the same row is updated while the session is enabled, the
+** resulting changeset will contain an UPDATE change that updates both fields.

+** considered compatible if all of the following are true:
+**
+** <ul>
+**   <li> The table has the same name as the name recorded in the
+**        changeset, and
+**   <li> The table has at least as many columns as recorded in the
+**        changeset, and
+**   <li> The table has primary key columns in the same position as
+**        recorded in the changeset.
+** </ul>
+**
+** If there is no compatible table, it is not an error, but none of the
+** changes associated with the table are applied. A warning message is issued
+** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
+** one such warning is issued for each table in the changeset.
+**
+** For each change for which there is a compatible table, an attempt is made
+** to modify the table contents according to the UPDATE, INSERT or DELETE
+** change. If a change cannot be applied cleanly, the conflict handler
+** function passed as the fifth argument to sqlite3changeset_apply() may be
+** invoked. A description of exactly when the conflict handler is invoked for
+** each type of change is below.
+**
+** Unlike the xFilter argument, xConflict may not be passed NULL. The results
+** of passing anything other than a valid function pointer as the xConflict
+** argument are undefined.
+**
+** Each time the conflict handler function is invoked, it must return one
+** of [SQLITE_CHANGESET_OMIT], [SQLITE_CHANGESET_ABORT] or
+** [SQLITE_CHANGESET_REPLACE]. SQLITE_CHANGESET_REPLACE may only be returned
+** if the second argument passed to the conflict handler is either
+** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
+** returns an illegal value, any changes already made are rolled back and
+** the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different
+** actions are taken by sqlite3changeset_apply() depending on the value
+** returned by each invocation of the conflict-handler function. Refer to
+** the documentation for the three
+** [SQLITE_CHANGESET_OMIT|available return values] for details.
+**
+** <dl>
+** <dt>DELETE Changes<dd>
+**   For each DELETE change, the function checks if the target database
+**   contains a row with the same primary key value (or values) as the
+**   original row values stored in the changeset. If it does, and the values
+**   stored in all non-primary key columns also match the values stored in
+**   the changeset the row is deleted from the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the non-primary key fields contains a value different from the original
+**   row value stored in the changeset, the conflict-handler function is
+**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
+**   database table has more columns than are recorded in the changeset,
+**   only the values of those non-primary key fields are compared against
+**   the current database contents - any trailing database table columns
+**   are ignored.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
+**   (which can only happen if a foreign key constraint is violated), the
+**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
+**   passed as the second argument. This includes the case where the DELETE
+**   operation is attempted because an earlier call to the conflict handler
+**   function returned [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>INSERT Changes<dd>
+**   For each INSERT change, an attempt is made to insert the new row into
+**   the database. If the changeset row contains fewer fields than the
+**   database table, the trailing fields are populated with their default
+**   values.
+**
+**   If the attempt to insert the row fails because the database already
+**   contains a row with the same primary key values, the conflict handler
+**   function is invoked with the second argument set to
+**   [SQLITE_CHANGESET_CONFLICT].
+**
+**   If the attempt to insert the row fails because of some other constraint
+**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is
+**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
+**   This includes the case where the INSERT operation is re-attempted because
+**   an earlier call to the conflict handler function returned
+**   [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>UPDATE Changes<dd>
+**   For each UPDATE change, the function checks if the target database
+**   contains a row with the same primary key value (or values) as the
+**   original row values stored in the changeset. If it does, and the values
+**   stored in all modified non-primary key columns also match the values
+**   stored in the changeset the row is updated within the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the modified non-primary key fields contains a value different from an
+**   original row value stored in the changeset, the conflict-handler function
+**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
+**   UPDATE changes only contain values for non-primary key fields that are
+**   to be modified, only those fields need to match the original values to
+**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the UPDATE operation is attempted, but SQLite returns
+**   SQLITE_CONSTRAINT, the conflict-handler function is invoked with
+**   [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
+**   This includes the case where the UPDATE operation is attempted after
+**   an earlier call to the conflict handler function returned
+**   [SQLITE_CHANGESET_REPLACE].

+**
+** It is safe to execute SQL statements, including those that write to the
+** table that the callback related to, from within the xConflict callback.
+** This can be used to further customize the application's conflict
+** resolution strategy.
+**
+** All changes made by these functions are enclosed in a savepoint transaction.
+** If any other error (aside from a constraint failure when attempting to
+** write to the target database) occurs, then the savepoint transaction is
+** rolled back, restoring the target database to its original state, and an
+** SQLite error code returned.
+**
+** If the output parameters (ppRebase) and (pnRebase) are non-NULL and
+** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
+** may set (*ppRebase) to point to a "rebase" that may be used with the

+** CAPI3REF: Rebasing changesets
+** EXPERIMENTAL
+**
+** Suppose there is a site hosting a database in state S0. And that
+** modifications are made that move that database to state S1 and a
+** changeset recorded (the "local" changeset). Then, a changeset based
+** on S0 is received from another site (the "remote" changeset) and
+** applied to the database. The database is then in state
+** (S1+"remote"), where the exact state depends on any conflict
+** resolution decisions (OMIT or REPLACE) made while applying "remote".
+** Rebasing a changeset is to update it to take those conflict
+** resolution decisions into account, so that the same conflicts
+** do not have to be resolved elsewhere in the network.
+**
+** For example, if both the local and remote changesets contain an
+** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
+**
+**   local:  INSERT INTO t1 VALUES(1, 'v1');
+**   remote: INSERT INTO t1 VALUES(1, 'v2');
+**
+** and the conflict resolution is REPLACE, then the INSERT change is
+** removed from the local changeset (it was overridden). Or, if the
+** conflict resolution was "OMIT", then the local changeset is modified
+** to instead contain:
+**
+**           UPDATE t1 SET b = 'v2' WHERE a=1;
+**
+** Changes within the local changeset are rebased as follows:
+**
+** <dl>
+** <dt>Local INSERT<dd>
+**   This may only conflict with a remote INSERT. If the conflict
+**   resolution was OMIT, then add an UPDATE change to the rebased
+**   changeset. Or, if the conflict resolution was REPLACE, add
+**   nothing to the rebased changeset.
+**
+** <dt>Local DELETE<dd>
+**   This may conflict with a remote UPDATE or DELETE. In both cases the
+**   only possible resolution is OMIT. If the remote operation was a
+**   DELETE, then add no change to the rebased changeset. If the remote
+**   operation was an UPDATE, then the old.* fields of change are updated
+**   to reflect the new.* values in the UPDATE.
+**
+** <dt>Local UPDATE<dd>
+**   This may conflict with a remote UPDATE or DELETE. If it conflicts
+**   with a DELETE, and the conflict resolution was OMIT, then the update
+**   is changed into an INSERT. Any undefined values in the new.* record
+**   from the update change are filled in using the old.* values from
+**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+**   the UPDATE change is simply omitted from the rebased changeset.
+**
+**   If conflict is with a remote UPDATE and the resolution is OMIT, then
+**   the old.* values are rebased using the new.* values in the remote
+**   change. Or, if the resolution is REPLACE, then the change is copied
+**   into the rebased changeset with updates to columns also updated by
+**   the conflicting remote UPDATE removed. If this means no columns would
+**   be updated, the change is omitted.
+** </dl>
+**
+** A local change may be rebased against multiple remote changes
+** simultaneously. If a single key is modified by multiple remote
+** changesets, they are combined as follows before the local changeset
+** is rebased:
+**
+** <ul>
+**    <li> If there has been one or more REPLACE resolutions on a
+**         key, it is rebased according to a REPLACE.
+**
+**    <li> If there have been no REPLACE resolutions on a key, then
+**         the local changeset is rebased according to the most recent
+**         of the OMIT resolutions.
+** </ul>
+**
+** Note that conflict resolutions from multiple remote changesets are
+** combined on a per-field basis, not per-row. This means that in the
+** case of multiple remote UPDATE operations, some fields of a single
+** local change may be rebased for REPLACE while others are rebased for
+** OMIT.
+**
+** In order to rebase a local changeset, the remote changeset must first
+** be applied to the local database using sqlite3changeset_apply_v2() and
+** the buffer of rebase information captured. Then:
+**
+** <ol>
+**   <li> An sqlite3_rebaser object is created by calling
+**        sqlite3rebaser_create().
+**   <li> The new object is configured with the rebase buffer obtained from
+**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+**        If the local changeset is to be rebased against multiple remote
+**        changesets, then sqlite3rebaser_configure() should be called
+**        multiple times, in the same order that the multiple
+**        sqlite3changeset_apply_v2() calls were made.

+** Non-streaming functions that accept changesets (or patchsets) as input
+** require that the entire changeset be stored in a single buffer in memory.
+** Similarly, those that return a changeset or patchset do so by returning
+** a pointer to a single large buffer allocated using sqlite3_malloc().
+** Normally this is convenient. However, if an application running in a
+** low-memory environment is required to handle very large changesets, the
+** large contiguous memory allocations required can become onerous.
+**
+** In order to avoid this problem, instead of a single large buffer, input
+** is passed to a streaming API functions by way of a callback function that
+** the sessions module invokes to incrementally request input data as it is
+** required. In all cases, a pair of API function parameters such as
+**
+**  <pre>
+**  &nbsp;     int nChangeset,
+**  &nbsp;     void *pChangeset,
+**  </pre>
+**
+** Is replaced by:
+**
+**  <pre>
+**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+**  &nbsp;     void *pIn,
+**  </pre>
+**
+** Each time the xInput callback is invoked by the sessions module, the first
+** argument passed is a copy of the supplied pIn context pointer. The second
+** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no
+** error occurs the xInput method should copy up to (*pnData) bytes of data
+** into the buffer and set (*pnData) to the actual number of bytes copied
+** before returning SQLITE_OK. If the input is completely exhausted, (*pnData)
+** should be set to zero to indicate this. Or, if an error occurs, an SQLite
+** error code should be returned. In all cases, if an xInput callback returns
+** an error, all processing is abandoned and the streaming API function
+** returns a copy of the error code to the caller.
+**
+** In the case of sqlite3changeset_start_strm(), the xInput callback may be
+** invoked by the sessions module at any point during the lifetime of the
+** iterator. If such an xInput callback returns an error, the iterator enters
+** an error state, whereby all subsequent calls to iterator functions
+** immediately fail with the same error code as returned by xInput.
+**
+** Similarly, streaming API functions that return changesets (or patchsets)
+** return them in chunks by way of a callback function instead of via a
+** pointer to a single large buffer. In this case, a pair of parameters such
+** as:
+**
+**  <pre>
+**  &nbsp;     int *pnChangeset,
+**  &nbsp;     void **ppChangeset,
+**  </pre>
+**
+** Is replaced by:
+**
+**  <pre>
+**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+**  &nbsp;     void *pOut
+**  </pre>
+**
+** The xOutput callback is invoked zero or more times to return data to
+** the application. The first parameter passed to each call is a copy of the
+** pOut pointer supplied by the application. The second parameter, pData,
+** points to a buffer nData bytes in size containing the chunk of output
+** data being returned. If the xOutput callback successfully processes the
+** supplied data, it should return SQLITE_OK to indicate success. Otherwise,

+** EXTENSION API FUNCTIONS
+**
+** xUserData(pFts):
+**   Return a copy of the context pointer the extension function was
+**   registered with.
+**
+** xColumnTotalSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the FTS5 table. Or, if iCol is
+**   non-negative but less than the number of columns in the table, return
+**   the total number of tokens in column iCol, considering all rows in
+**   the FTS5 table.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+** xColumnCount(pFts):
+**   Return the number of columns in the table.
+**
+** xColumnSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the current row. Or, if iCol is
+**   non-negative but less than the number of columns in the table, set
+**   *pnToken to the number of tokens in column iCol of the current row.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is
+**   returned.
+**
+**   This function may be quite inefficient if used with an FTS5 table
+**   created with the "columnsize=0" option.
+**
+** xColumnText:
+**   This function attempts to retrieve the text of column iCol of the
+**   current document. If successful, (*pz) is set to point to a buffer
+**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+**   if an error occurs, an SQLite error code is returned and the final values
+**   of (*pz) and (*pn) are undefined.
+**
+** xPhraseCount:
+**   Returns the number of phrases in the current query expression.
+**
+** xPhraseSize:
+**   Returns the number of tokens in phrase iPhrase of the query. Phrases
+**   are numbered starting from zero.
+**
+** xInstCount:
+**   Set *pnInst to the total number of occurrences of all phrases within
+**   the query within the current row. Return SQLITE_OK if successful, or
+**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always returns 0.
+**
+** xInst:
+**   Query for the details of phrase match iIdx within the current row.
+**   Phrase matches are numbered starting from zero, so the iIdx argument
+**   should be greater than or equal to zero and smaller than the value
+**   output by xInstCount().
+**
+**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
+**   to the column in which it occurs and *piOff the token offset of the
+**   first token of the phrase. Returns SQLITE_OK if successful, or an error
+**   code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option.
+**
+** xRowid:
+**   Returns the rowid of the current row.
+**
+** xTokenize:
+**   Tokenize text using the tokenizer belonging to the FTS5 table.
+**
+** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+**   This API function is used to query the FTS table for phrase iPhrase
+**   of the current query. Specifically, a query equivalent to:
+**
+**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+**
+**   with $p set to a phrase equivalent to the phrase iPhrase of the
+**   current query is executed. Any column filter that applies to
+**   phrase iPhrase of the current query is included in $p. For each
+**   row visited, the callback function passed as the fourth argument
+**   is invoked. The context and API objects passed to the callback
+**   function may be used to access the properties of each matched row.
+**   Invoking Api.xUserData() returns a copy of the pointer passed as
+**   the third argument to pUserData.
+**
+**   If the callback function returns any value other than SQLITE_OK, the
+**   query is abandoned and the xQueryPhrase function returns immediately.
+**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+**   Otherwise, the error code is propagated upwards.
+**
+**   If the query runs to completion without incident, SQLITE_OK is returned.
+**   Or, if some error occurs before the query completes or is aborted by
+**   the callback, an SQLite error code is returned.
+**
+**
+** xSetAuxdata(pFts5, pAux, xDelete)
+**
+**   Save the pointer passed as the second argument as the extension function's
+**   "auxiliary data". The pointer may then be retrieved by the current or any
+**   future invocation of the same fts5 extension function made as part of
+**   the same MATCH query using the xGetAuxdata() API.
+**
+**   Each extension function is allocated a single auxiliary data slot for
+**   each FTS query (MATCH expression). If the extension function is invoked
+**   more than once for a single FTS query, then all invocations share a
+**   single auxiliary data context.
+**
+**   If there is already an auxiliary data pointer when this function is
+**   invoked, then it is replaced by the new pointer. If an xDelete callback
+**   was specified along with the original pointer, it is invoked at this
+**   point.
+**
+**   The xDelete callback, if one is specified, is also invoked on the
+**   auxiliary data pointer after the FTS5 query has finished.
+**
+**   If an error (e.g. an OOM condition) occurs within this function,
+**   the auxiliary data is set to NULL and an error code returned. If the
+**   xDelete parameter was not NULL, it is invoked on the auxiliary data
+**   pointer before returning.
+**
+**
+** xGetAuxdata(pFts5, bClear)
+**
+**   Returns the current auxiliary data pointer for the fts5 extension
+**   function. See the xSetAuxdata() method for details.
+**
+**   If the bClear argument is non-zero, then the auxiliary data is cleared
+**   (set to NULL) before this function returns. In this case the xDelete,
+**   if any, is not invoked.
+**
+**
+** xRowCount(pFts5, pnRow)
+**
+**   This function is used to retrieve the total number of rows in the table.
+**   In other words, the same value that would be returned by:
+**
+**        SELECT count(*) FROM ftstable;
+**
+** xPhraseFirst()
+**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
+**   method, to iterate through all instances of a single query phrase within
+**   the current row. This is the same information as is accessible via the
+**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+**   to use, this API may be faster under some circumstances. To iterate
+**   through instances of phrase iPhrase, use the following code:
+**
+**       Fts5PhraseIter iter;
+**       int iCol, iOff;
+**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+**           iCol>=0;
+**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+**       ){
+**         // An instance of phrase iPhrase at offset iOff of column iCol
+**       }
+**
+**   The Fts5PhraseIter structure is defined above. Applications should not
+**   modify this structure directly - it should only be used as shown above
+**   with the xPhraseFirst() and xPhraseNext() API methods (and by
+**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created
+**   with either "detail=none" or "detail=column" and "content=" option
+**   (i.e. if it is a contentless table), then this API always iterates
+**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
+**
+** xPhraseNext()
+**   See xPhraseFirst above.
+**
+** xPhraseFirstColumn()
+**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+**   and xPhraseNext() APIs described above. The difference is that instead
+**   of iterating through all instances of a phrase in the current row, these
+**   APIs are used to iterate through the set of columns in the current row
+**   that contain one or more instances of a specified phrase. For example:
+**
+**       Fts5PhraseIter iter;
+**       int iCol;
+**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+**           iCol>=0;
+**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+**       ){
+**         // Column iCol contains at least one instance of phrase iPhrase
+**       }
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" option. If the FTS5 table is created with either
+**   "detail=none" "content=" option (i.e. if it is a contentless table),
+**   then this API always iterates through an empty set (all calls to
+**   xPhraseFirstColumn() set iCol to -1).
+**
+**   The information accessed using this API and its companion
+**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+**   (or xInst/xInstCount). The chief advantage of this API is that it is
+**   significantly more efficient than those alternatives when used with
+**   "detail=column" tables.
+**
+** xPhraseNextColumn()
+**   See xPhraseFirstColumn above.

+** CUSTOM AUXILIARY FUNCTIONS
+*************************************************************************/
+
+/*************************************************************************
+** CUSTOM TOKENIZERS
+**
+** Applications may also register custom tokenizer types. A tokenizer
+** is registered by providing fts5 with a populated instance of the
+** following structure. All structure methods must be defined, setting
+** any member of the fts5_tokenizer struct to NULL leads to undefined
+** behaviour. The structure methods are expected to function as follows:
+**
+** xCreate:
+**   This function is used to allocate and initialize a tokenizer instance.
+**   A tokenizer instance is required to actually tokenize text.
+**
+**   The first argument passed to this function is a copy of the (void*)
+**   pointer provided by the application when the fts5_tokenizer object
+**   was registered with FTS5 (the third argument to xCreateTokenizer()).
+**   The second and third arguments are an array of nul-terminated strings
+**   containing the tokenizer arguments, if any, specified following the
+**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
+**   to create the FTS5 table.
+**
+**   The final argument is an output variable. If successful, (*ppOut)
+**   should be set to point to the new tokenizer handle and SQLITE_OK
+**   returned. If an error occurs, some value other than SQLITE_OK should
+**   be returned. In this case, fts5 assumes that the final value of *ppOut
+**   is undefined.
+**
+** xDelete:
+**   This function is invoked to delete a tokenizer handle previously
+**   allocated using xCreate(). Fts5 guarantees that this function will
+**   be invoked exactly once for each successful call to xCreate().
+**
+** xTokenize:
+**   This function is expected to tokenize the nText byte string indicated
+**   by argument pText. pText may or may not be nul-terminated. The first
+**   argument passed to this function is a pointer to an Fts5Tokenizer object
+**   returned by an earlier call to xCreate().
+**
+**   The second argument indicates the reason that FTS5 is requesting
+**   tokenization of the supplied text. This is always one of the following
+**   four values:
+**
+**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
+**            or removed from the FTS table. The tokenizer is being invoked to
+**            determine the set of tokens to add to (or delete from) the
+**            FTS index.
+**
+**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed
+**            against the FTS index. The tokenizer is being called to tokenize
+**            a bareword or quoted string specified as part of the query.
+**
+**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
+**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
+**            followed by a "*" character, indicating that the last token
+**            returned by the tokenizer will be treated as a token prefix.
+**
+**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to
+**            satisfy an fts5_api.xTokenize() request made by an auxiliary
+**            function. Or an fts5_api.xColumnSize() request made by the same
+**            on a columnsize=0 database.
+**   </ul>
+**
+**   For each token in the input string, the supplied callback xToken() must
+**   be invoked. The first argument to it should be a copy of the pointer
+**   passed as the second argument to xTokenize(). The third and fourth
+**   arguments are a pointer to a buffer containing the token text, and the
+**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
+**   of the first byte of and first byte immediately following the text from
+**   which the token is derived within the input.
+**
+**   The second argument passed to the xToken() callback ("tflags") should
+**   normally be set to 0. The exception is if the tokenizer supports
+**   synonyms. In this case see the discussion below for details.
+**
+**   FTS5 assumes the xToken() callback is invoked for each token in the
+**   order that they occur within the input text.
+**
+**   If an xToken() callback returns any value other than SQLITE_OK, then
+**   the tokenization should be abandoned and the xTokenize() method should
+**   immediately return a copy of the xToken() return value. Or, if the
+**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
+**   if an error occurs with the xTokenize() implementation itself, it
+**   may abandon the tokenization and return any error code other than
+**   SQLITE_OK or SQLITE_DONE.
+**
+** SYNONYM SUPPORT
+**
+**   Custom tokenizers may also support synonyms. Consider a case in which a
+**   user wishes to query for a phrase such as "first place". Using the
+**   built-in tokenizers, the FTS5 query 'first + place' will match instances
+**   of "first place" within the document set, but not alternative forms
+**   such as "1st place". In some applications, it would be better to match
+**   all instances of "first place" or "1st place" regardless of which form
+**   the user specified in the MATCH query text.
+**
+**   There are several ways to approach this in FTS5:
+**
+**   <ol><li> By mapping all synonyms to a single token. In this case, using
+**            the above example, this means that the tokenizer returns the
+**            same token for inputs "first" and "1st". Say that token is in
+**            fact "first", so that when the user inserts the document "I won
+**            1st place" entries are added to the index for tokens "i", "won",
+**            "first" and "place". If the user then queries for '1st + place',
+**            the tokenizer substitutes "first" for "1st" and the query works
+**            as expected.
+**
+**       <li> By querying the index for all synonyms of each query term
+**            separately. In this case, when tokenizing query text, the
+**            tokenizer may provide multiple synonyms for a single term
+**            within the document. FTS5 then queries the index for each
+**            synonym individually. For example, faced with the query:
+**
+**   <codeblock>
+**     ... MATCH 'first place'</codeblock>
+**
+**            the tokenizer offers both "1st" and "first" as synonyms for the
+**            first token in the MATCH query and FTS5 effectively runs a query
+**            similar to:
+**
+**   <codeblock>
+**     ... MATCH '(first OR 1st) place'</codeblock>
+**
+**            except that, for the purposes of auxiliary functions, the query
+**            still appears to contain just two phrases - "(first OR 1st)"
+**            being treated as a single phrase.
+**
+**       <li> By adding multiple synonyms for a single term to the FTS index.
+**            Using this method, when tokenizing document text, the tokenizer
+**            provides multiple synonyms for each token. So that when a
+**            document such as "I won first place" is tokenized, entries are
+**            added to the FTS index for "i", "won", "first", "1st" and
+**            "place".
+**
+**            This way, even if the tokenizer does not provide synonyms
+**            when tokenizing query text (it should not - to do so would be
+**            inefficient), it doesn't matter if the user queries for
+**            'first + place' or '1st + place', as there are entries in the
+**            FTS index corresponding to both forms of the first token.
+**   </ol>
+**
+**   Whether it is parsing document or query text, any call to xToken that
+**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
+**   is considered to supply a synonym for the previous token. For example,
+**   when parsing the document "I won first place", a tokenizer that supports
+**   synonyms would call xToken() 5 times, as follows:
+**
+**   <codeblock>
+**       xToken(pCtx, 0, "i",                      1,  0,  1);
+**       xToken(pCtx, 0, "won",                    3,  2,  5);
+**       xToken(pCtx, 0, "first",                  5,  6, 11);
+**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
+**       xToken(pCtx, 0, "place",                  5, 12, 17);
+**</codeblock>
+**
+**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
+**   xToken() is called. Multiple synonyms may be specified for a single token
+**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence.
+**   There is no limit to the number of synonyms that may be provided for a
+**   single token.
+**
+**   In many cases, method (1) above is the best approach. It does not add
+**   extra data to the FTS index or require FTS5 to query for multiple terms,
+**   so it is efficient in terms of disk space and query speed. However, it
+**   does not support prefix queries very well. If, as suggested above, the
+**   token "first" is substituted for "1st" by the tokenizer, then the query:
+**
+**   <codeblock>
+**     ... MATCH '1s*'</codeblock>
+**
+**   will not match documents that contain the token "1st" (as the tokenizer
+**   will probably not map "1s" to any prefix of "first").
+**
+**   For full prefix support, method (3) may be preferred. In this case,
+**   because the index contains entries for both "first" and "1st", prefix
+**   queries such as 'fi*' or '1s*' will match correctly. However, because
+**   extra entries are added to the FTS index, this method uses more space
+**   within the database.
+**
+**   Method (2) offers a midpoint between (1) and (3). Using this method,
+**   a query such as '1s*' will match documents that contain the literal
+**   token "1st", but not "first" (assuming the tokenizer is not able to
+**   provide synonyms for prefixes). However, a non-prefix query like '1st'
+**   will match against "1st" and "first". This method does not require
+**   extra disk space, as no extra entries are added to the FTS index.
+**   On the other hand, it may require more CPU cycles to run MATCH queries,
+**   as separate queries of the FTS index are required for each synonym.
+**
+**   When using methods (2) or (3), it is important that the tokenizer only
+**   provide synonyms when tokenizing document text (method (2)) or query
+**   text (method (3)), not both. Doing so will not cause any errors, but is
+**   inefficient.

+// This function is uses a caesar-cypher by default
+// and is used within the UserAuthentication module to encode
+// the password.
+//
+// The provided functions can be used as an overload to the sqlite_crypt
+// function through the use of the RegisterFunc on the connection.
+//
+// Because the functions can serv a purpose to an end-user
+// without using the UserAuthentication module
+// the functions are default compiled in.
+//
+// From SQLITE3 - user-auth.txt
+// The sqlite_user.pw field is encoded by a built-in SQL function
+// "sqlite_crypt(X,Y)".  The two arguments are both BLOBs.  The first argument
+// is the plaintext password supplied to the sqlite3_user_authenticate()
+// interface.  The second argument is the sqlite_user.pw value and is supplied
+// so that the function can extract the "salt" used by the password encoder.
+// The result of sqlite_crypt(X,Y) is another blob which is the value that
+// ends up being stored in sqlite_user.pw.  To verify credentials X supplied
+// by the sqlite3_user_authenticate() routine, SQLite runs:
+//
+//     sqlite_user.pw == sqlite_crypt(X, sqlite_user.pw)
+//
+// To compute an appropriate sqlite_user.pw value from a new or modified
+// password X, sqlite_crypt(X,NULL) is run.  A new random salt is selected
+// when the second argument is NULL.
+//
+// The built-in version of of sqlite_crypt() uses a simple Caesar-cypher
+// which prevents passwords from being revealed by searching the raw database
+// for ASCII text, but is otherwise trivally broken.  For better password
+// security, the database should be encrypted using the SQLite Encryption
+// Extension or similar technology.  Or, the application can use the

+
+Package errors provides simple error handling primitives.
+
+`go get github.com/pkg/errors`
+
+The traditional error handling idiom in Go is roughly akin to
+```go
+if err != nil {
+        return err
+}
+```
+which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
+
+## Adding context to an error
+
+The errors.Wrap function returns a new error that adds context to the original error. For example
+```go
+_, err := ioutil.ReadAll(r)
+if err != nil {
+        return errors.Wrap(err, "read failed")
+}
+```
+## Retrieving the cause of an error
+
+Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
+```go
+type causer interface {
+        Cause() error
+}
+```
+`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
+```go
+switch err := errors.Cause(err).(type) {
+case *MyError:
+        // handle specifically
+default:
+        // unknown error
+}
+```
+
+[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).
+
+## Roadmap
+
+With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
+
+- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
+- 1.0. Final release.
+
+## Contributing
+
+Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports. 
+
+Before sending a PR, please discuss your change by raising an issue.

+// Package errors provides simple error handling primitives.
+//
+// The traditional error handling idiom in Go is roughly akin to
+//
+//     if err != nil {
+//             return err
+//     }
+//
+// which when applied recursively up the call stack results in error reports
+// without context or debugging information. The errors package allows
+// programmers to add context to the failure path in their code in a way
+// that does not destroy the original value of the error.
+//
+// Adding context to an error
+//
+// The errors.Wrap function returns a new error that adds context to the
+// original error by recording a stack trace at the point Wrap is called,
+// together with the supplied message. For example
+//
+//     _, err := ioutil.ReadAll(r)
+//     if err != nil {
+//             return errors.Wrap(err, "read failed")
+//     }
+//
+// If additional control is required, the errors.WithStack and
+// errors.WithMessage functions destructure errors.Wrap into its component
+// operations: annotating an error with a stack trace and with a message,
+// respectively.
+//
+// Retrieving the cause of an error
+//
+// Using errors.Wrap constructs a stack of errors, adding context to the
+// preceding error. Depending on the nature of the error it may be necessary
+// to reverse the operation of errors.Wrap to retrieve the original error
+// for inspection. Any error value which implements this interface
+//
+//     type causer interface {
+//             Cause() error
+//     }
+//
+// can be inspected by errors.Cause. errors.Cause will recursively retrieve
+// the topmost error that does not implement causer, which is assumed to be
+// the original cause. For example:
+//
+//     switch err := errors.Cause(err).(type) {
+//     case *MyError:
+//             // handle specifically
+//     default:
+//             // unknown error
+//     }
+//
+// Although the causer interface is not exported by this package, it is
+// considered a part of its stable public interface.
+//
+// Formatted printing of errors
+//
+// All error values returned from this package implement fmt.Formatter and can
+// be formatted by the fmt package. The following verbs are supported:
+//
+//     %s    print the error. If the error has a Cause it will be
+//           printed recursively.
+//     %v    see %s
+//     %+v   extended format. Each Frame of the error's StackTrace will
+//           be printed in detail.
+//
+// Retrieving the stack trace of an error or wrapper
+//
+// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
+// invoked. This information can be retrieved with the following interface:
+//
+//     type stackTracer interface {
+//             StackTrace() errors.StackTrace
+//     }
+//
+// The returned errors.StackTrace type is defined as
+//
+//     type StackTrace []Frame
+//
+// The Frame type represents a call site in the stack trace. Frame supports
+// the fmt.Formatter interface that can be used for printing information about
+// the stack trace of this error. For example:
+//
+//     if err, ok := err.(stackTracer); ok {
+//             for _, f := range err.StackTrace() {
+//                     fmt.Printf("%+s:%d\n", f, f)
+//             }
+//     }
+//
+// Although the stackTracer interface is not exported by this package, it is
+// considered a part of its stable public interface.
+//
+// See the documentation for Frame.Format for more details.

+# Unicode Text Segmentation for Go
+
+[![Godoc Reference](https://img.shields.io/badge/godoc-reference-blue.svg)](https://godoc.org/github.com/rivo/uniseg)
+[![Go Report](https://img.shields.io/badge/go%20report-A%2B-brightgreen.svg)](https://goreportcard.com/report/github.com/rivo/uniseg)
+
+This Go package implements Unicode Text Segmentation according to [Unicode Standard Annex #29](http://unicode.org/reports/tr29/) (Unicode version 12.0.0).
+
+At this point, only the determination of grapheme cluster boundaries is implemented.
+
+## Background
+
+In Go, [strings are read-only slices of bytes](https://blog.golang.org/strings). They can be turned into Unicode code points using the `for` loop or by casting: `[]rune(str)`. However, multiple code points may be combined into one user-perceived character or what the Unicode specification calls "grapheme cluster". Here are some examples:
+
+|String|Bytes (UTF-8)|Code points (runes)|Grapheme clusters|
+|-|-|-|-|
+|Käse|6 bytes: `4b 61 cc 88 73 65`|5 code points: `4b 61 308 73 65`|4 clusters: `[4b],[61 308],[73],[65]`|
+|🏳️‍🌈|14 bytes: `f0 9f 8f b3 ef b8 8f e2 80 8d f0 9f 8c 88`|4 code points: `1f3f3 fe0f 200d 1f308`|1 cluster: `[1f3f3 fe0f 200d 1f308]`|
+|🇩🇪|8 bytes: `f0 9f 87 a9 f0 9f 87 aa`|2 code points: `1f1e9 1f1ea`|1 cluster: `[1f1e9 1f1ea]`|
+
+This package provides a tool to iterate over these grapheme clusters. This may be used to determine the number of user-perceived characters, to split strings in their intended places, or to extract individual characters which form a unit.
+
+## Installation
+
+```bash
+go get github.com/rivo/uniseg
+```
+
+## Basic Example
+
+```go
+package uniseg
+
+import (
+	"fmt"
+
+	"github.com/rivo/uniseg"
+)
+
+func main() {
+	gr := uniseg.NewGraphemes("👍🏼!")
+	for gr.Next() {
+		fmt.Printf("%x ", gr.Runes())
+	}
+	// Output: [1f44d 1f3fc] [21]
+}
+```

+Package `journald` offers Go implementation of systemd Journal's native API for logging. Key features are:
+
+* based on a connection-less socket
+* work with messages of any size and type
+* client can use any number of separate sockets
+
+## Installation
+
+Install the package with:
+
+```shell
+go get github.com/ssgreg/journald
+```
+
+## Usage: The Best Way
+
+The Best Way to use structured logs (systemd Journal, etc.) is [logf](https://github.com/ssgreg/logf) - the fast, asynchronous, structured logger in Go with zero allocation count and it's journald driver [logfjournald](https://github.com/ssgreg/logfjournald). This driver uses `journald` package.
+The following example creates the new `logf` logger with `logfjournald` appender.
+
+```go
+package main
+
+import (
+    "runtime"
+
+    "github.com/ssgreg/logf"
+    "github.com/ssgreg/logfjournald"
+)
+
+func main() {
+    // Create journald Appender with default journald Encoder.
+    appender, appenderClose := logfjournald.NewAppender(logfjournald.NewEncoder.Default())
+    defer appenderClose()
+
+    // Create ChannelWriter with journald Encoder.
+    writer, writerClose := logf.NewChannelWriter(logf.ChannelWriterConfig{
+        Appender: appender,
+    })
+    defer writerClose()
+
+    // Create Logger with ChannelWriter.
+    logger := logf.NewLogger(logf.LevelInfo, writer)
+
+    logger.Info("got cpu info", logf.Int("count", runtime.NumCPU()))
+}
+```
+
+The JSON representation of the journal entry this generates:
+
+```json
+{
+  "TS": "2018-11-01T07:25:18Z",
+  "PRIORITY": "6",
+  "LEVEL": "info",
+  "MESSAGE": "got cpu info",
+  "COUNT": "4",
+}
+```
+
+## Usage: AS-IS
+
+Let's look at what the `journald` provides as Go APIs for logging:
+
+```go
+package main
+
+import (
+    "github.com/ssgreg/journald"
+)
+
+func main() {
+    journald.Print(journald.PriorityInfo, "Hello World!")
+}
+```
+
+The JSON representation of the journal entry this generates:
+
+```json
+{
+    "PRIORITY": "6",
+    "MESSAGE":  "Hello World!",
+    "_PID":     "3965",
+    "_COMM":    "simple",
+    "...":      "..."
+}
+```
+
+The primary reason for using the Journal's native logging APIs is not just plain logs: it is to allow passing additional structured log messages from the program into the journal. This additional log data may the be used to search the journal for, is available for consumption for other programs, and might help the administrator to track down issues beyond what is expressed in the human readable message text. Here's an example how to do that with `journals.Send`:
+
+```go
+package main
+
+import (
+    "os"
+    "runtime"
+
+    "github.com/ssgreg/journald"
+)
+
+func main() {
+    journald.Send("Hello World!", journald.PriorityInfo, map[string]interface{}{
+        "HOME":        os.Getenv("HOME"),
+        "TERM":        os.Getenv("TERM"),
+        "N_GOROUTINE": runtime.NumGoroutine(),
+        "N_CPUS":      runtime.NumCPU(),
+        "TRACE":       runtime.ReadTrace(),
+    })
+}
+```
+
+This will write a log message to the journal much like the earlier examples. However, this times a few additional, structured fields are attached:
+
+```json
+{
+    "PRIORITY":     "6",
+    "MESSAGE":      "Hello World!",
+    "HOME":         "/root",
+    "TERM":         "xterm",
+    "N_GOROUTINE":  "2",
+    "N_CPUS":       "4",
+    "TRACE":        [103,111,32,49,46,56,32,116,114,97,99,101,0,0,0,0],
+    "_PID":         "4037",
+    "_COMM":        "send",
+    "...":          "..."
+}
+```
+
+Our structured message includes seven fields. The first two we passed are well-known fields:
+
+1. `MESSAGE=` is the actual human readable message part of the structured message.
+1. `PRIORITY=` is the numeric message priority value as known from BSD syslog formatted as an integer string.
+
+Applications may relatively freely define additional fields as they see fit (we defined four pretty arbitrary ones in our example). A complete list of the currently well-known fields is available [here](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html).
+

+# Multi Progress Bar
+
+[![GoDoc](https://pkg.go.dev/badge/github.com/vbauerster/mpb)](https://pkg.go.dev/github.com/vbauerster/mpb/v6)
+[![Build Status](https://travis-ci.org/vbauerster/mpb.svg?branch=master)](https://travis-ci.org/vbauerster/mpb)
+[![Go Report Card](https://goreportcard.com/badge/github.com/vbauerster/mpb)](https://goreportcard.com/report/github.com/vbauerster/mpb)
+
+**mpb** is a Go lib for rendering progress bars in terminal applications.
+
+## Features
+
+- **Multiple Bars**: Multiple progress bars are supported
+- **Dynamic Total**: Set total while bar is running
+- **Dynamic Add/Remove**: Dynamically add or remove bars
+- **Cancellation**: Cancel whole rendering process
+- **Predefined Decorators**: Elapsed time, [ewma](https://github.com/VividCortex/ewma) based ETA, Percentage, Bytes counter
+- **Decorator's width sync**: Synchronized decorator's width among multiple bars
+
+## Usage
+
+#### [Rendering single bar](_examples/singleBar/main.go)
+
+```go
+package main
+
+import (
+    "math/rand"
+    "time"

+
+    total := 100
+    name := "Single Bar:"
+    // adding a single bar, which will inherit container's width
+    bar := p.Add(int64(total),
+        // progress bar filler with customized style

+        bar.Increment()
+    }
+    // wait for our bar to complete and flush
+    p.Wait()
+}
+```
+
+#### [Rendering multiple bars](_examples/multiBars/main.go)
+
+```go

+# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]
+
+Simple wrappers for primitive types to enforce atomic access.
+
+## Installation
+
+```shell
+$ go get -u go.uber.org/atomic@v1
+```
+
+### Legacy Import Path
+
+As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
+of using this package. If you are using Go modules, this package will fail to
+compile with the legacy import path path `github.com/uber-go/atomic`.
+
+We recommend migrating your code to the new import path but if you're unable
+to do so, or if your dependencies are still using the old import path, you
+will have to add a `replace` directive to your `go.mod` file downgrading the
+legacy import path to an older version.
+
+```
+replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
+```
+
+You can do so automatically by running the following command.
+
+```shell
+$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
+```
+
+## Usage
+
+The standard library's `sync/atomic` is powerful, but it's easy to forget which
+variables must be accessed atomically. `go.uber.org/atomic` preserves all the
+functionality of the standard library, but wraps the primitive types to
+provide a safer, more convenient API.
+
+```go
+var atom atomic.Uint32
+atom.Store(42)
+atom.Sub(2)
+atom.CAS(40, 11)
+```
+
+See the [documentation][doc] for a complete API specification.
+

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+  // Structured context as loosely typed key-value pairs.
+  "url", url,
+  "attempt", 3,
+  "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+  // Structured context as strongly typed Field values.
+  zap.String("url", url),
+  zap.Int("attempt", 3),
+  zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive &mdash; they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users *choose* when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages &mdash; it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.<sup
+id="anchor-versions">[1](#footnote-versions)</sup>
+
+Log a message and 10 fields:
+
+{{.BenchmarkAddingFields}}
+
+Log a message with a logger that already has 10 fields of context:
+
+{{.BenchmarkAccumulatedContext}}
+
+Log a static string, without any context or `printf`-style templating:
+
+{{.BenchmarkWithoutFields}}
+
+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors &mdash;
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+# Changelog
+All notable changes to this project will be documented in this file.
+
+This project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+
+## 1.23.0 (24 Aug 2022)
+
+Enhancements:
+* [#1147][]: Add a `zapcore.LevelOf` function to determine the level of a
+  `LevelEnabler` or `Core`.
+* [#1155][]: Add `zap.Stringers` field constructor to log arrays of objects
+  that implement `String() string`.
+
+[#1147]: https://github.com/uber-go/zap/pull/1147
+[#1155]: https://github.com/uber-go/zap/pull/1155
+
+
+## 1.22.0 (8 Aug 2022)
+
+Enhancements:
+* [#1071][]: Add `zap.Objects` and `zap.ObjectValues` field constructors to log
+  arrays of objects. With these two constructors, you don't need to implement
+  `zapcore.ArrayMarshaler` for use with `zap.Array` if those objects implement
+  `zapcore.ObjectMarshaler`.
+* [#1079][]: Add `SugaredLogger.WithOptions` to build a copy of an existing
+  `SugaredLogger` with the provided options applied.
+* [#1080][]: Add `*ln` variants to `SugaredLogger` for each log level.
+  These functions provide a string joining behavior similar to `fmt.Println`.
+* [#1088][]: Add `zap.WithFatalHook` option to control the behavior of the
+  logger for `Fatal`-level log entries. This defaults to exiting the program.
+* [#1108][]: Add a `zap.Must` function that you can use with `NewProduction` or
+  `NewDevelopment` to panic if the system was unable to build the logger.
+* [#1118][]: Add a `Logger.Log` method that allows specifying the log level for
+  a statement dynamically.
+
+Thanks to @cardil, @craigpastro, @sashamelentyev, @shota3506, and @zhupeijun
+for their contributions to this release.

+## v1.5.0 (22 Jul 2017)
+
+Enhancements:
+
+* [#460][] and [#470][]: Support errors produced by `go.uber.org/multierr`.
+* [#465][]: Support user-supplied encoders for logger names.
+
+Bugfixes:
+
+* [#477][]: Fix a bug that incorrectly truncated deep stacktraces.
+
+Thanks to @richard-tunein and @pavius for their contributions to this release.
+
+## v1.4.1 (08 Jun 2017)
+
+This release fixes two bugs.
+
+Bugfixes:
+
+* [#435][]: Support a variety of case conventions when unmarshaling levels.
+* [#444][]: Fix a panic in the observer.
+
+## v1.4.0 (12 May 2017)
+
+This release adds a few small features and is fully backward-compatible.
+
+Enhancements:
+
+* [#424][]: Add a `LineEnding` field to `EncoderConfig`, allowing users to
+  override the Unix-style default.
+* [#425][]: Preserve time zones when logging times.
+* [#431][]: Make `zap.AtomicLevel` implement `fmt.Stringer`, which makes a
+  variety of operations a bit simpler.
+
+## v1.3.0 (25 Apr 2017)
+
+This release adds an enhancement to zap's testing helpers as well as the
+ability to marshal an AtomicLevel. It is fully backward-compatible.
+
+Enhancements:
+
+* [#415][]: Add a substring-filtering helper to zap's observer. This is
+  particularly useful when testing the `SugaredLogger`.
+* [#416][]: Make `AtomicLevel` implement `encoding.TextMarshaler`.
+
+## v1.2.0 (13 Apr 2017)
+
+This release adds a gRPC compatibility wrapper. It is fully backward-compatible.
+
+Enhancements:
+
+* [#402][]: Add a `zapgrpc` package that wraps zap's Logger and implements
+  `grpclog.Logger`.
+
+## v1.1.0 (31 Mar 2017)
+
+This release fixes two bugs and adds some enhancements to zap's testing helpers.
+It is fully backward-compatible.
+
+Bugfixes:
+
+* [#385][]: Fix caller path trimming on Windows.
+* [#396][]: Fix a panic when attempting to use non-existent directories with
+  zap's configuration struct.
+
+Enhancements:
+
+* [#386][]: Add filtering helpers to zaptest's observing logger.
+
+Thanks to @moitias for contributing to this release.
+
+## v1.0.0 (14 Mar 2017)
+
+This is zap's first stable release. All exported APIs are now final, and no
+further breaking changes will be made in the 1.x release series. Anyone using a
+semver-aware dependency manager should now pin to `^1`.
+
+Breaking changes:
+
+* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without
+  casting from `[]byte` to `string`.
+* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`,
+  `zap.Logger`, and `zap.SugaredLogger`.
+* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to
+  clash with other testing helpers.
+
+Bugfixes:
+
+* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier
+  for tab-separated console output.
+* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to
+  work with concurrency-safe `WriteSyncer` implementations.
+* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux
+  systems.
+* [#373][]: Report the correct caller from zap's standard library
+  interoperability wrappers.
+
+Enhancements:
+
+* [#348][]: Add a registry allowing third-party encodings to work with zap's
+  built-in `Config`.
+* [#327][]: Make the representation of logger callers configurable (like times,
+  levels, and durations).
+* [#376][]: Allow third-party encoders to use their own buffer pools, which
+  removes the last performance advantage that zap's encoders have over plugins.
+* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple
+  `WriteSyncer`s and lock the result.
+* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in
+  Go 1.9).
+* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it
+  easier for particularly punctilious users to unit test their application's
+  logging.
+
+Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their
+contributions to this release.
+
+## v1.0.0-rc.3 (7 Mar 2017)
+
+This is the third release candidate for zap's stable release. There are no
+breaking changes.
+
+Bugfixes:
+
+* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs
+  rather than `[]uint8`.
+
+Enhancements:
+
+* [#307][]: Users can opt into colored output for log levels.
+* [#353][]: In addition to hijacking the output of the standard library's
+  package-global logging functions, users can now construct a zap-backed
+  `log.Logger` instance.
+* [#311][]: Frames from common runtime functions and some of zap's internal
+  machinery are now omitted from stacktraces.
+
+Thanks to @ansel1 and @suyash for their contributions to this release.
+
+## v1.0.0-rc.2 (21 Feb 2017)
+
+This is the second release candidate for zap's stable release. It includes two
+breaking changes.
+
+Breaking changes:
+
+* [#316][]: Zap's global loggers are now fully concurrency-safe
+  (previously, users had to ensure that `ReplaceGlobals` was called before the
+  loggers were in use). However, they must now be accessed via the `L()` and
+  `S()` functions. Users can update their projects with
+
+  ```
+  gofmt -r "zap.L -> zap.L()" -w .
+  gofmt -r "zap.S -> zap.S()" -w .
+  ```
+* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid
+  JSON and YAML struct tags on all config structs. This release fixes the tags
+  and adds static analysis to prevent similar bugs in the future.
+
+Bugfixes:
+
+* [#321][]: Redirecting the standard library's `log` output now
+  correctly reports the logger's caller.
+
+Enhancements:
+
+* [#325][] and [#333][]: Zap now transparently supports non-standard, rich
+  errors like those produced by `github.com/pkg/errors`.
+* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is
+  now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) ->
+  zap.NewNop()' -w .`.
+* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a
+  more informative error.
+
+Thanks to @skipor and @chapsuk for their contributions to this release.
+
+## v1.0.0-rc.1 (14 Feb 2017)
+
+This is the first release candidate for zap's stable release. There are multiple
+breaking changes and improvements from the pre-release version. Most notably:
+
+* **Zap's import path is now "go.uber.org/zap"** &mdash; all users will
+  need to update their code.
+* User-facing types and functions remain in the `zap` package. Code relevant
+  largely to extension authors is now in the `zapcore` package.
+* The `zapcore.Core` type makes it easy for third-party packages to use zap's
+  internals but provide a different user-facing API.
+* `Logger` is now a concrete type instead of an interface.
+* A less verbose (though slower) logging API is included by default.
+* Package-global loggers `L` and `S` are included.
+* A human-friendly console encoder is included.
+* A declarative config struct allows common logger configurations to be managed
+  as configuration instead of code.
+* Sampling is more accurate, and doesn't depend on the standard library's shared
+  timer heap.
+
+## v0.1.0-beta.1 (6 Feb 2017)
+
+This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and
+upgrade at their leisure. Since this is the first tagged release, there are no
+backward compatibility concerns and all functionality is new.
+
+Early zap adopters should pin to the 0.1.x minor version until they're ready to
+upgrade to the upcoming stable release.

+# Frequently Asked Questions
+
+## Design
+
+### Why spend so much effort on logger performance?
+
+Of course, most applications won't notice the impact of a slow logger: they
+already take tens or hundreds of milliseconds for each operation, so an extra
+millisecond doesn't matter.
+
+On the other hand, why *not* make structured logging fast? The `SugaredLogger`
+isn't any harder to use than other logging packages, and the `Logger` makes
+structured logging possible in performance-sensitive contexts. Across a fleet
+of Go microservices, making each application even slightly more efficient adds
+up quickly.
+
+### Why aren't `Logger` and `SugaredLogger` interfaces?
+
+Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and
+`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points
+out][go-proverbs], "The bigger the interface, the weaker the abstraction."
+Interfaces are also rigid &mdash; *any* change requires releasing a new major
+version, since it breaks all third-party implementations.
+
+Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much
+abstraction, and it lets us add methods without introducing breaking changes.
+Your applications should define and depend upon an interface that includes
+just the methods you use.
+
+### Why are some of my logs missing?
+
+Logs are dropped intentionally by zap when sampling is enabled. The production
+configuration (as returned by `NewProductionConfig()` enables sampling which will
+cause repeated logs within a second to be sampled. See more details on why sampling
+is enabled in [Why sample application logs](https://github.com/uber-go/zap/blob/master/FAQ.md#why-sample-application-logs).
+
+### Why sample application logs?
+
+Applications often experience runs of errors, either because of a bug or
+because of a misbehaving user. Logging errors is usually a good idea, but it
+can easily make this bad situation worse: not only is your application coping
+with a flood of errors, it's also spending extra CPU cycles and I/O logging
+those errors. Since writes are typically serialized, logging limits throughput
+when you need it most.
+
+Sampling fixes this problem by dropping repetitive log entries. Under normal
+conditions, your application writes out every entry. When similar entries are
+logged hundreds or thousands of times each second, though, zap begins dropping
+duplicates to preserve throughput.
+
+### Why do the structured logging APIs take a message in addition to fields?
+
+Subjectively, we find it helpful to accompany structured context with a brief
+description. This isn't critical during development, but it makes debugging
+and operating unfamiliar systems much easier.
+
+More concretely, zap's sampling algorithm uses the message to identify
+duplicate entries. In our experience, this is a practical middle ground
+between random sampling (which often drops the exact entry that you need while
+debugging) and hashing the complete entry (which is prohibitively expensive).
+
+### Why include package-global loggers?
+
+Since so many other logging packages include a global logger, many
+applications aren't designed to accept loggers as explicit parameters.
+Changing function signatures is often a breaking change, so zap includes
+global loggers to simplify migration.
+
+Avoid them where possible.
+
+### Why include dedicated Panic and Fatal log levels?
+
+In general, application code should handle errors gracefully instead of using
+`panic` or `os.Exit`. However, every rule has exceptions, and it's common to
+crash when an error is truly unrecoverable. To avoid losing any information
+&mdash; especially the reason for the crash &mdash; the logger must flush any
+buffered entries before the process exits.
+
+Zap makes this easy by offering `Panic` and `Fatal` logging methods that
+automatically flush before exiting. Of course, this doesn't guarantee that
+logs will never be lost, but it eliminates a common error.
+
+See the discussion in uber-go/zap#207 for more details.
+
+### What's `DPanic`?
+
+`DPanic` stands for "panic in development." In development, it logs at
+`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to
+catch errors that are theoretically possible, but shouldn't actually happen,
+*without* crashing in production.
+
+If you've ever written code like this, you need `DPanic`:
+
+```go
+if err != nil {
+  panic(fmt.Sprintf("shouldn't ever get here: %v", err))
+}
+```
+
+## Installation
+
+### What does the error `expects import "go.uber.org/zap"` mean?
+
+Either zap was installed incorrectly or you're referencing the wrong package
+name in your code.
+
+Zap's source code happens to be hosted on GitHub, but the [import
+path][import-path] is `go.uber.org/zap`. This gives us, the project
+maintainers, the freedom to move the source code if necessary. However, it
+means that you need to take a little care when installing and using the
+package.
+
+If you follow two simple rules, everything should work: install zap with `go
+get -u go.uber.org/zap`, and always import it in your code with `import
+"go.uber.org/zap"`. Your code shouldn't contain *any* references to
+`github.com/uber-go/zap`.
+
+## Usage
+
+### Does zap support log rotation?
+
+Zap doesn't natively support rotating log files, since we prefer to leave this
+to an external program like `logrotate`.
+
+However, it's easy to integrate a log rotation package like
+[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`.
+
+```go
+// lumberjack.Logger is already safe for concurrent use, so we don't need to
+// lock it.
+w := zapcore.AddSync(&lumberjack.Logger{
+  Filename:   "/var/log/myapp/foo.log",
+  MaxSize:    500, // megabytes
+  MaxBackups: 3,
+  MaxAge:     28, // days
+})
+core := zapcore.NewCore(
+  zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()),
+  w,
+  zap.InfoLevel,
+)
+logger := zap.New(core)
+```
+
+## Extensions
+
+We'd love to support every logging need within zap itself, but we're only
+familiar with a handful of log ingestion systems, flag-parsing packages, and
+the like. Rather than merging code that we can't effectively debug and
+support, we'd rather grow an ecosystem of zap extensions.
+
+We're aware of the following extensions, but haven't used them ourselves:
+
+| Package | Integration |
+| --- | --- |
+| `github.com/tchap/zapext` | Sentry, syslog |
+| `github.com/fgrosse/zaptest` | Ginkgo |
+| `github.com/blendle/zapdriver` | Stackdriver |
+| `github.com/moul/zapgorm` | Gorm |
+| `github.com/moul/zapfilter` | Advanced filtering rules |

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+  // Structured context as loosely typed key-value pairs.
+  "url", url,
+  "attempt", 3,
+  "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+  // Structured context as strongly typed Field values.
+  zap.String("url", url),
+  zap.Int("attempt", 3),
+  zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive &mdash; they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users _choose_ when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages &mdash; it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.<sup

+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors &mdash;
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+
+// Package zap provides fast, structured, leveled logging.
+//
+// For applications that log in the hot path, reflection-based serialization
+// and string formatting are prohibitively expensive - they're CPU-intensive
+// and make many small allocations. Put differently, using json.Marshal and
+// fmt.Fprintf to log tons of interface{} makes your application slow.
+//
+// Zap takes a different approach. It includes a reflection-free,
+// zero-allocation JSON encoder, and the base Logger strives to avoid
+// serialization overhead and allocations wherever possible. By building the
+// high-level SugaredLogger on that foundation, zap lets users choose when
+// they need to count every allocation and when they'd prefer a more familiar,
+// loosely typed API.
+//
+// # Choosing a Logger
+//
+// In contexts where performance is nice, but not critical, use the
+// SugaredLogger. It's 4-10x faster than other structured logging packages and
+// supports both structured and printf-style logging. Like log15 and go-kit,
+// the SugaredLogger's structured logging APIs are loosely typed and accept a
+// variadic number of key-value pairs. (For more advanced use cases, they also
+// accept strongly typed fields - see the SugaredLogger.With documentation for
+// details.)
+//
+//	sugar := zap.NewExample().Sugar()
+//	defer sugar.Sync()
+//	sugar.Infow("failed to fetch URL",
+//	  "url", "http://example.com",
+//	  "attempt", 3,
+//	  "backoff", time.Second,
+//	)
+//	sugar.Infof("failed to fetch URL: %s", "http://example.com")
+//
+// By default, loggers are unbuffered. However, since zap's low-level APIs
+// allow buffering, calling Sync before letting your process exit is a good
+// habit.
+//
+// In the rare contexts where every microsecond and every allocation matter,
+// use the Logger. It's even faster than the SugaredLogger and allocates far
+// less, but it only supports strongly-typed, structured logging.
+//
+//	logger := zap.NewExample()
+//	defer logger.Sync()
+//	logger.Info("failed to fetch URL",
+//	  zap.String("url", "http://example.com"),
+//	  zap.Int("attempt", 3),
+//	  zap.Duration("backoff", time.Second),
+//	)
+//
+// Choosing between the Logger and SugaredLogger doesn't need to be an
+// application-wide decision: converting between the two is simple and
+// inexpensive.
+//
+//	logger := zap.NewExample()
+//	defer logger.Sync()
+//	sugar := logger.Sugar()
+//	plain := sugar.Desugar()
+//
+// # Configuring Zap
+//
+// The simplest way to build a Logger is to use zap's opinionated presets:
+// NewExample, NewProduction, and NewDevelopment. These presets build a logger
+// with a single function call:
+//
+//	logger, err := zap.NewProduction()
+//	if err != nil {
+//	  log.Fatalf("can't initialize zap logger: %v", err)
+//	}
+//	defer logger.Sync()
+//
+// Presets are fine for small projects, but larger projects and organizations
+// naturally require a bit more customization. For most users, zap's Config
+// struct strikes the right balance between flexibility and convenience. See
+// the package-level BasicConfiguration example for sample code.
+//
+// More unusual configurations (splitting output between files, sending logs
+// to a message queue, etc.) are possible, but require direct use of
+// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
+// example for sample code.
+//
+// # Extending Zap
+//
+// The zap package itself is a relatively thin wrapper around the interfaces
+// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
+// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
+// exception aggregation service, like Sentry or Rollbar) typically requires
+// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
+// interfaces. See the zapcore documentation for details.
+//
+// Similarly, package authors can use the high-performance Encoder and Core
+// implementations in the zapcore package to build their own loggers.
+//
+// # Frequently Asked Questions
+//
+// An FAQ covering everything from installation errors to design decisions is
+// available at https://github.com/uber-go/zap/blob/master/FAQ.md.

+// The GET request returns a JSON description of the current logging level like:

+// A SugaredLogger wraps the base Logger functionality in a slower, but less

+// method.
+//
+// Unlike the Logger, the SugaredLogger doesn't insist on structured logging.
+// For each log level, it exposes four methods:
+//
+//   - methods named after the log level for log.Print-style logging
+//   - methods ending in "w" for loosely-typed structured logging
+//   - methods ending in "f" for log.Printf-style logging
+//   - methods ending in "ln" for log.Println-style logging
+//
+// For example, the methods for InfoLevel are:
+//
+//	Info(...any)           Print-style logging
+//	Infow(...any)          Structured logging (read as "info with")
+//	Infof(string, ...any)  Printf-style logging
+//	Infoln(...any)         Println-style logging

+// mix of strongly-typed Field objects and loosely-typed key-value pairs. When
+// processing pairs, the first element of the pair is used as the field key
+// and the second as the field value.
+//
+// For example,

+# Contributing to Go
+
+Go is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+## Filing issues
+
+When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
+
+1.  What version of Go are you using (`go version`)?
+2.  What operating system and processor architecture are you using?
+3.  What did you do?
+4.  What did you expect to see?
+5.  What did you see instead?
+
+General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
+The gophers there will answer or ask you to file an issue if you've tripped over a bug.
+
+## Contributing code

+This subrepository holds experimental and deprecated (in the `old`

+
+The idea for this subrepository originated as the `pkg/exp` directory

+# Checking Go Package API Compatibility
+
+The `apidiff` tool in this directory determines whether two versions of the same
+package are compatible. The goal is to help the developer make an informed
+choice of semantic version after they have changed the code of their module.
+
+`apidiff` reports two kinds of changes: incompatible ones, which require
+incrementing the major part of the semantic version, and compatible ones, which
+require a minor version increment. If no API changes are reported but there are
+code changes that could affect client code, then the patch version should
+be incremented.
+
+Because `apidiff` ignores package import paths, it may be used to display API
+differences between any two packages, not just different versions of the same
+package.
+
+The current version of `apidiff` compares only packages, not modules.
+
+
+## Compatibility Desiderata
+
+Any tool that checks compatibility can offer only an approximation. No tool can
+detect behavioral changes; and even if it could, whether a behavioral change is
+a breaking change or not depends on many factors, such as whether it closes a
+security hole or fixes a bug. Even a change that causes some code to fail to
+compile may not be considered a breaking change by the developers or their
+users. It may only affect code marked as experimental or unstable, for
+example, or the break may only manifest in unlikely cases.
+
+For a tool to be useful, its notion of compatibility must be relaxed enough to
+allow reasonable changes, like adding a field to a struct, but strict enough to
+catch significant breaking changes. A tool that is too lax will miss important
+incompatibilities, and users will stop trusting it; one that is too strict may
+generate so much noise that users will ignore it.
+
+To a first approximation, this tool reports a change as incompatible if it could
+cause client code to stop compiling. But `apidiff` ignores five ways in which
+code may fail to compile after a change. Three of them are mentioned in the
+[Go 1 Compatibility Guarantee](https://golang.org/doc/go1compat).
+
+### Unkeyed Struct Literals
+
+Code that uses an unkeyed struct literal would fail to compile if a field was
+added to the struct, making any such addition an incompatible change. An example:
+
+```
+// old
+type Point struct { X, Y int }
+
+// new
+type Point struct { X, Y, Z int }
+
+// client
+p := pkg.Point{1, 2} // fails in new because there are more fields than expressions
+```
+Here and below, we provide three snippets: the code in the old version of the
+package, the code in the new version, and the code written in a client of the package,
+which refers to it by the name `pkg`. The client code compiles against the old
+code but not the new.
+
+### Embedding and Shadowing
+
+Adding an exported field to a struct can break code that embeds that struct,
+because the newly added field may conflict with an identically named field
+at the same struct depth. A selector referring to the latter would become
+ambiguous and thus erroneous.
+
+
+```
+// old
+type Point struct { X, Y int }
+
+// new
+type Point struct { X, Y, Z int }
+
+// client
+type z struct { Z int }
+
+var v struct {
+    pkg.Point
+    z
+}
+
+_ = v.Z // fails in new
+```
+In the new version, the last line fails to compile because there are two embedded `Z`
+fields at the same depth, one from `z` and one from `pkg.Point`.
+
+
+### Using an Identical Type Externally
+
+If it is possible for client code to write a type expression representing the
+underlying type of a defined type in a package, then external code can use it in
+assignments involving the package type, making any change to that type incompatible.
+```
+// old
+type Point struct { X, Y int }
+
+// new
+type Point struct { X, Y, Z int }
+
+// client
+var p struct { X, Y int } = pkg.Point{} // fails in new because of Point's extra field
+```
+Here, the external code could have used the provided name `Point`, but chose not
+to. I'll have more to say about this and related examples later.
+
+### unsafe.Sizeof and Friends
+
+Since `unsafe.Sizeof`, `unsafe.Offsetof` and `unsafe.Alignof` are constant
+expressions, they can be used in an array type literal:
+
+```
+// old
+type S struct{ X int }
+
+// new
+type S struct{ X, y int }
+
+// client
+var a [unsafe.Sizeof(pkg.S{})]int = [8]int{} // fails in new because S's size is not 8
+```
+Use of these operations could make many changes to a type potentially incompatible.
+
+
+### Type Switches
+
+A package change that merges two different types (with same underlying type)
+into a single new type may break type switches in clients that refer to both
+original types:
+
+```
+// old
+type T1 int
+type T2 int
+
+// new
+type T1 int
+type T2 = T1
+
+// client
+switch x.(type) {
+case T1:
+case T2:
+} // fails with new because two cases have the same type
+```
+This sort of incompatibility is sufficiently esoteric to ignore; the tool allows
+merging types.
+
+## First Attempt at a Definition
+
+Our first attempt at defining compatibility captures the idea that all the
+exported names in the old package must have compatible equivalents in the new
+package.
+
+A new package is compatible with an old one if and only if:
+- For every exported package-level name in the old package, the same name is
+  declared in the new at package level, and
+- the names denote the same kind of object (e.g. both are variables), and
+- the types of the objects are compatible.
+
+We will work out the details (and make some corrections) below, but it is clear
+already that we will need to determine what makes two types compatible. And
+whatever the definition of type compatibility, it's certainly true that if two
+types are the same, they are compatible. So we will need to decide what makes an
+old and new type the same. We will call this sameness relation _correspondence_.
+
+## Type Correspondence
+
+Go already has a definition of when two types are the same:
+[type identity](https://golang.org/ref/spec#Type_identity).
+But identity isn't adequate for our purpose: it says that two defined
+types are identical if they arise from the same definition, but it's unclear
+what "same" means when talking about two different packages (or two versions of
+a single package).
+
+The obvious change to the definition of identity is to require that old and new
+[defined types](https://golang.org/ref/spec#Type_definitions)
+have the same name instead. But that doesn't work either, for two
+reasons. First, type aliases can equate two defined types with different names:
+
+```
+// old
+type E int
+
+// new
+type t int
+type E = t
+```
+Second, an unexported type can be renamed:
+
+```
+// old
+type u1 int
+var V u1
+
+// new
+type u2 int
+var V u2
+```
+Here, even though `u1` and `u2` are unexported, their exported fields and
+methods are visible to clients, so they are part of the API. But since the name
+`u1` is not visible to clients, it can be changed compatibly. We say that `u1`
+and `u2` are _exposed_: a type is exposed if a client package can declare variables of that type.
+
+We will say that an old defined type _corresponds_ to a new one if they have the
+same name, or one can be renamed to the other without otherwise changing the
+API. In the first example above, old `E` and new `t` correspond. In the second,
+old `u1` and new `u2` correspond.
+
+Two or more old defined types can correspond to a single new type: we consider
+"merging" two types into one to be a compatible change. As mentioned above,
+code that uses both names in a type switch will fail, but we deliberately ignore
+this case. However, a single old type can correspond to only one new type.
+
+So far, we've explained what correspondence means for defined types. To extend
+the definition to all types, we parallel the language's definition of type
+identity. So, for instance, an old and a new slice type correspond if their
+element types correspond.
+
+## Definition of Compatibility
+
+We can now present the definition of compatibility used by `apidiff`.
+
+### Package Compatibility
+
+> A new package is compatible with an old one if:
+>1. Each exported name in the old package's scope also appears in the new
+>package's scope, and the object (constant, variable, function or type) denoted
+>by that name in the old package is compatible with the object denoted by the
+>name in the new package, and
+>2. For every exposed type that implements an exposed interface in the old package,
+> its corresponding type should implement the corresponding interface in the new package.
+>
+>Otherwise the packages are incompatible.
+
+As an aside, the tool also finds exported names in the new package that are not
+exported in the old, and marks them as compatible changes.
+
+Clause 2 is discussed further in "Whole-Package Compatibility."
+
+### Object Compatibility
+
+This section provides compatibility rules for constants, variables, functions
+and types.
+
+#### Constants
+
+>A new exported constant is compatible with an old one of the same name if and only if
+>1. Their types correspond, and
+>2. Their values are identical.
+
+It is tempting to allow changing a typed constant to an untyped one. That may
+seem harmless, but it can break code like this:
+
+```
+// old
+const C int64 = 1
+
+// new
+const C = 1
+
+// client
+var x = C          // old type is int64, new is int
+var y int64 = x // fails with new: different types in assignment
+```
+
+A change to the value of a constant can break compatibility if the value is used
+in an array type:
+
+```
+// old
+const C = 1
+
+// new
+const C = 2
+
+// client
+var a [C]int = [1]int{} // fails with new because [2]int and [1]int are different types
+```
+Changes to constant values are rare, and determining whether they are compatible
+or not is better left to the user, so the tool reports them.
+
+#### Variables
+
+>A new exported variable is compatible with an old one of the same name if and
+>only if their types correspond.
+
+Correspondence doesn't look past names, so this rule does not prevent adding a
+field to `MyStruct` if the package declares `var V MyStruct`. It does, however, mean that
+
+```
+var V struct { X int }
+```
+is incompatible with
+```
+var V struct { X, Y int }
+```
+I discuss this at length below in the section "Compatibility, Types and Names."
+
+#### Functions
+
+>A new exported function or variable is compatible with an old function of the
+>same name if and only if their types (signatures) correspond.
+
+This rule captures the fact that, although many signature changes are compatible
+for all call sites, none are compatible for assignment:
+
+```
+var v func(int) = pkg.F
+```
+Here, `F` must be of type `func(int)` and not, for instance, `func(...int)` or `func(interface{})`.
+
+Note that the rule permits changing a function to a variable. This is a common
+practice, usually done for test stubbing, and cannot break any code at compile
+time.
+
+#### Exported Types
+
+> A new exported type is compatible with an old one if and only if their
+> names are the same and their types correspond.
+
+This rule seems far too strict. But, ignoring aliases for the moment, it demands only
+that the old and new _defined_ types correspond. Consider:
+```
+// old
+type T struct { X int }
+
+// new
+type T struct { X, Y int }
+```
+The addition of `Y` is a compatible change, because this rule does not require
+that the struct literals have to correspond, only that the defined types
+denoted by `T` must correspond. (Remember that correspondence stops at type
+names.)
+
+If one type is an alias that refers to the corresponding defined type, the
+situation is the same:
+
+```
+// old
+type T struct { X int }
+
+// new
+type u struct { X, Y int }
+type T = u
+```
+Here, the only requirement is that old `T` corresponds to new `u`, not that the
+struct types correspond. (We can't tell from this snippet that the old `T` and
+the new `u` do correspond; that depends on whether `u` replaces `T` throughout
+the API.)
+
+However, the following change is incompatible, because the names do not
+denote corresponding types:
+
+```
+// old
+type T = struct { X int }
+
+// new
+type T = struct { X, Y int }
+```
+### Type Literal Compatibility
+
+Only five kinds of types can differ compatibly: defined types, structs,
+interfaces, channels and numeric types. We only consider the compatibility of
+the last four when they are the underlying type of a defined type. See
+"Compatibility, Types and Names" for a rationale.
+
+We justify the compatibility rules by enumerating all the ways a type
+can be used, and by showing that the allowed changes cannot break any code that
+uses values of the type in those ways.
+
+Values of all types can be used in assignments (including argument passing and
+function return), but we do not require that old and new types are assignment
+compatible. That is because we assume that the old and new packages are never
+used together: any given binary will link in either the old package or the new.
+So in describing how a type can be used in the sections below, we omit
+assignment.
+
+Any type can also be used in a type assertion or conversion. The changes we allow
+below may affect the run-time behavior of these operations, but they cannot affect
+whether they compile. The only such breaking change would be to change
+the type `T` in an assertion `x.T` so that it no longer implements the interface
+type of `x`; but the rules for interfaces below disallow that.
+
+> A new type is compatible with an old one if and only if they correspond, or
+> one of the cases below applies.
+
+#### Defined Types
+
+Other than assignment, the only ways to use a defined type are to access its
+methods, or to make use of the properties of its underlying type. Rule 2 below
+covers the latter, and rules 3 and 4 cover the former.
+
+> A new defined type is compatible with an old one if and only if all of the
+> following hold:
+>1. They correspond.
+>2. Their underlying types are compatible.
+>3. The new exported value method set is a superset of the old.
+>4. The new exported pointer method set is a superset of the old.
+
+An exported method set is a method set with all unexported methods removed.
+When comparing methods of a method set, we require identical names and
+corresponding signatures.
+
+Removing an exported method is clearly a breaking change. But removing an
+unexported one (or changing its signature) can be breaking as well, if it
+results in the type no longer implementing an interface. See "Whole-Package
+Compatibility," below.
+
+#### Channels
+
+> A new channel type is compatible with an old one if
+>  1. The element types correspond, and
+>  2. Either the directions are the same, or the new type has no direction.
+
+Other than assignment, the only ways to use values of a channel type are to send
+and receive on them, to close them, and to use them as map keys. Changes to a
+channel type cannot cause code that closes a channel or uses it as a map key to
+fail to compile, so we need not consider those operations.
+
+Rule 1 ensures that any operations on the values sent or received will compile.
+Rule 2 captures the fact that any program that compiles with a directed channel
+must use either only sends, or only receives, so allowing the other operation
+by removing the channel direction cannot break any code.
+
+
+#### Interfaces
+
+> A new interface is compatible with an old one if and only if:
+> 1. The old interface does not have an unexported method, and it corresponds
+>    to the new interfaces (i.e. they have the same method set), or
+> 2. The old interface has an unexported method and the new exported method set is a
+>    superset of the old.
+
+Other than assignment, the only ways to use an interface are to implement it,
+embed it, or call one of its methods. (Interface values can also be used as map
+keys, but that cannot cause a compile-time error.)
+
+Certainly, removing an exported method from an interface could break a client
+call, so neither rule allows it.
+
+Rule 1 also disallows adding a method to an interface without an existing unexported
+method. Such an interface can be implemented in client code. If adding a method
+were allowed, a type that implements the old interface could fail to implement
+the new one:
+
+```
+type I interface { M1() }         // old
+type I interface { M1(); M2() }   // new
+
+// client
+type t struct{}
+func (t) M1() {}
+var i pkg.I = t{} // fails with new, because t lacks M2
+```
+
+Rule 2 is based on the observation that if an interface has an unexported
+method, the only way a client can implement it is to embed it.
+Adding a method is compatible in this case, because the embedding struct will
+continue to implement the interface. Adding a method also cannot break any call
+sites, since no program that compiles could have any such call sites.
+
+#### Structs
+
+> A new struct is compatible with an old one if all of the following hold:
+> 1. The new set of top-level exported fields is a superset of the old.
+> 2. The new set of _selectable_ exported fields is a superset of the old.
+> 3. If the old struct is comparable, so is the new one.
+
+The set of selectable exported fields is the set of exported fields `F`
+such that `x.F` is a valid selector expression for a value `x` of the struct
+type. `F` may be at the top level of the struct, or it may be a field of an
+embedded struct.
+
+Two fields are the same if they have the same name and corresponding types.
+
+Other than assignment, there are only four ways to use a struct: write a struct
+literal, select a field, use a value of the struct as a map key, or compare two
+values for equality. The first clause ensures that struct literals compile; the
+second, that selections compile; and the third, that equality expressions and
+map index expressions compile.
+
+#### Numeric Types
+
+> A new numeric type is compatible with an old one if and only if they are
+> both unsigned integers, both signed integers, both floats or both complex
+> types, and the new one is at least as large as the old on both 32-bit and
+> 64-bit architectures.
+
+Other than in assignments, numeric types appear in arithmetic and comparison
+expressions. Since all arithmetic operations but shifts (see below) require that
+operand types be identical, and by assumption the old and new types underly
+defined types (see "Compatibility, Types and Names," below), there is no way for
+client code to write an arithmetic expression that compiles with operands of the
+old type but not the new.
+
+Numeric types can also appear in type switches and type assertions. Again, since
+the old and new types underly defined types, type switches and type assertions
+that compiled using the old defined type will continue to compile with the new
+defined type.
+
+Going from an unsigned to a signed integer type is an incompatible change for
+the sole reason that only an unsigned type can appear as the right operand of a
+shift. If this rule is relaxed, then changes from an unsigned type to a larger
+signed type would be compatible. See [this
+issue](https://github.com/golang/go/issues/19113).
+
+Only integer types can be used in bitwise and shift operations, and for indexing
+slices and arrays. That is why switching from an integer to a floating-point
+type--even one that can represent all values of the integer type--is an
+incompatible change.
+
+
+Conversions from floating-point to complex types or vice versa are not permitted
+(the predeclared functions real, imag, and complex must be used instead). To
+prevent valid floating-point or complex conversions from becoming invalid,
+changing a floating-point type to a complex type or vice versa is considered an
+incompatible change.
+
+Although conversions between any two integer types are valid, assigning a
+constant value to a variable of integer type that is too small to represent the
+constant is not permitted. That is why the only compatible changes are to
+a new type whose values are a superset of the old. The requirement that the new
+set of values must include the old on both 32-bit and 64-bit machines allows
+conversions from `int32` to `int` and from `int` to `int64`, but not the other
+direction; and similarly for `uint`.
+
+Changing a type to or from `uintptr` is considered an incompatible change. Since
+its size is not specified, there is no way to know whether the new type's values
+are a superset of the old type's.
+
+## Whole-Package Compatibility
+
+Some changes that are compatible for a single type are not compatible when the
+package is considered as a whole. For example, if you remove an unexported
+method on a defined type, it may no longer implement an interface of the
+package. This can break client code:
+
+```
+// old
+type T int
+func (T) m() {}
+type I interface { m() }
+
+// new
+type T int // no method m anymore
+
+// client
+var i pkg.I = pkg.T{} // fails with new because T lacks m
+```
+
+Similarly, adding a method to an interface can cause defined types
+in the package to stop implementing it.
+
+The second clause in the definition for package compatibility handles these
+cases. To repeat:
+> 2. For every exposed type that implements an exposed interface in the old package,
+> its corresponding type should implement the corresponding interface in the new package.
+Recall that a type is exposed if it is part of the package's API, even if it is
+unexported.
+
+Other incompatibilities that involve more than one type in the package can arise
+whenever two types with identical underlying types exist in the old or new
+package. Here, a change "splits" an identical underlying type into two, breaking
+conversions:
+
+```
+// old
+type B struct { X int }
+type C struct { X int }
+
+// new
+type B struct { X int }
+type C struct { X, Y int }
+
+// client
+var b B
+_ = C(b) // fails with new: cannot convert B to C
+```
+Finally, changes that are compatible for the package in which they occur can
+break downstream packages. That can happen even if they involve unexported
+methods, thanks to embedding.
+
+The definitions given here don't account for these sorts of problems.
+
+
+## Compatibility, Types and Names 
+
+The above definitions state that the only types that can differ compatibly are
+defined types and the types that underly them. Changes to other type literals
+are considered incompatible. For instance, it is considered an incompatible
+change to add a field to the struct in this variable declaration:
+
+```
+var V struct { X int }
+```
+or this alias definition:
+```
+type T = struct { X int }
+```
+
+We make this choice to keep the definition of compatibility (relatively) simple.
+A more precise definition could, for instance, distinguish between
+
+```
+func F(struct { X int })
+```
+where any changes to the struct are incompatible, and
+
+```
+func F(struct { X, u int })
+```
+where adding a field is compatible (since clients cannot write the signature,
+and thus cannot assign `F` to a variable of the signature type). The definition
+should then also allow other function signature changes that only require
+call-site compatibility, like
+
+```
+func F(struct { X, u int }, ...int)
+```
+The result would be a much more complex definition with little benefit, since
+the examples in this section rarely arise in practice.

+// gorelease is an experimental tool that helps module authors avoid common
+// problems before releasing a new version of a module.
+//
+// Usage:
+//
+//	gorelease [-base={version|none}] [-version=version]
+//
+// Examples:
+//
+//	# Compare with the latest version and suggest a new version.
+//	gorelease
+//
+//	# Compare with a specific version and suggest a new version.
+//	gorelease -base=v1.2.3
+//
+//	# Compare with the latest version and check a specific new version for compatibility.
+//	gorelease -version=v1.3.0
+//
+//	# Compare with a specific version and check a specific new version for compatibility.
+//	gorelease -base=v1.2.3 -version=v1.3.0
+//
+// gorelease analyzes changes in the public API and dependencies of the main
+// module. It compares a base version (set with -base) with the currently
+// checked out revision. Given a proposed version to release (set with
+// -version), gorelease reports whether the changes are consistent with
+// semantic versioning. If no version is proposed with -version, gorelease
+// suggests the lowest version consistent with semantic versioning.
+//
+// If there are no visible changes in the module's public API, gorelease
+// accepts versions that increment the minor or patch version numbers. For
+// example, if the base version is "v2.3.1", gorelease would accept "v2.3.2" or
+// "v2.4.0" or any prerelease of those versions, like "v2.4.0-beta". If no
+// version is proposed, gorelease would suggest "v2.3.2".
+//
+// If there are only backward compatible differences in the module's public
+// API, gorelease only accepts versions that increment the minor version. For
+// example, if the base version is "v2.3.1", gorelease would accept "v2.4.0"
+// but not "v2.3.2".
+//
+// If there are incompatible API differences for a proposed version with
+// major version 1 or higher, gorelease will exit with a non-zero status.
+// Incompatible differences may only be released in a new major version, which
+// requires creating a module with a different path. For example, if
+// incompatible changes are made in the module "example.com/mod", a
+// new major version must be released as a new module, "example.com/mod/v2".
+// For a proposed version with major version 0, which allows incompatible
+// changes, gorelease will describe all changes, but incompatible changes
+// will not affect its exit status.
+//
+// For more information on semantic versioning, see https://semver.org.
+//
+// Note: gorelease does not accept build metadata in releases (like
+// v1.0.0+debug). Although it is valid semver, the Go tool and other tools in
+// the ecosystem do not support it, so its use is not recommended.
+//
+// gorelease accepts the following flags:
+//
+// -base=version: The version that the current version of the module will be
+// compared against. This may be a version like "v1.5.2", a version query like
+// "latest", or "none". If the version is "none", gorelease will not compare the
+// current version against any previous version; it will only validate the
+// current version. This is useful for checking the first release of a new major
+// version. The version may be preceded by a different module path and an '@',
+// like -base=example.com/mod/v2@v2.5.2. This is useful to compare against
+// an earlier major version or a fork. If -base is not specified, gorelease will
+// attempt to infer a base version from the -version flag and available released
+// versions.
+//
+// -version=version: The proposed version to be released. If specified,
+// gorelease will confirm whether this version is consistent with changes made
+// to the module's public API. gorelease will exit with a non-zero status if the
+// version is not valid.
+//
+// gorelease is eventually intended to be merged into the go command
+// as "go release". See golang.org/issues/26420.

+// IDEAS:
+// * Should we suggest versions at all or should -version be mandatory?
+// * Verify downstream modules have licenses. May need an API or library
+//   for this. Be clear that we can't provide legal advice.
+// * Internal packages may be relevant to submodules (for example,
+//   golang.org/x/tools/internal/lsp is imported by golang.org/x/tools).
+//   gorelease should detect whether this is the case and include internal
+//   directories in comparison. It should be possible to opt out or specify
+//   a different list of submodules.
+// * Decide what to do about build constraints, particularly GOOS and GOARCH.
+//   The API may be different on some platforms (e.g., x/sys).
+//   Should gorelease load packages in multiple configurations in the same run?
+//   Is it a compatible change if the same API is available for more platforms?
+//   Is it an incompatible change for fewer?
+//   How about cgo? Is adding a new cgo dependency an incompatible change?
+// * Support splits and joins of nested modules. For example, if we are
+//   proposing to tag a particular commit as both cloud.google.com/go v0.46.2
+//   and cloud.google.com/go/storage v1.0.0, we should ensure that the sets of
+//   packages provided by those modules are disjoint, and we should not report
+//   the packages moved from one to the other as an incompatible change (since
+//   the APIs are still compatible, just with a different module split).
+
+// TODO(jayconrod):
+// * Clean up overuse of fmt.Errorf.
+// * Support migration to modules after v2.x.y+incompatible. Requires comparing
+//   packages with different module paths.
+// * Error when packages import from earlier major version of same module.
+//   (this may be intentional; look for real examples first).
+// * Mechanism to suppress error messages.

+This directory contains most tests for gorelease. Each test runs gorelease (the
+`runRelease` function) with a given set of flags in a temporary directory
+populated with files specified in the test itself or files from the module test
+proxy. The output is compared against a golden `want` file specified in the
+test.
+
+## Test flags
+
+A specific test may be run with a command like:
+
+    go test -run=TestRelease/basic/v0_patch_suggest
+
+where `basic/v0_patch_suggest` matches the file
+`testdata/basic/v0_patch_suggest.test`.
+
+The `-u` flag adds or updates the `want` file in each test to match the output.
+This is useful for fixing tests after an intended change in behavior.
+
+    go test -run=TestRelease/basic/v0_patch_suggest -u
+
+The `-testwork` flag instructs the test framework to leave the test's temporary
+directory and module proxy in place after running the test. This is useful
+for debugging.
+
+## Test format
+
+Tests are written in `.test` files in `testdata` subdirectories. Each `.test`
+file is a valid txtar file (see `golang.org/x/tools/txtar`). The comment section
+contains the test parameters, which are a series of `key=value` pairs. Blank
+lines and comments starting with `#` are allowed in this section. Valid keys
+are:
+
+* `mod`: sets the module path. Must be specified together with `version`. Copies
+  the content of a module out of the test proxy into a temporary directory
+  where `gorelease` is run.
+* `version`: specified together with `mod`, it sets the version to retrieve from
+  the test proxy. See more information below.
+* `base`: the value of the `-base` flag passed to `gorelease`.
+* `release`: the value of the `-version` flag passed to `gorelease`.
+* `dir`: the directory where `gorelease` should be invoked. Useful when the test
+  describes a whole repository, and `gorelease` should be invoked in a
+  subdirectory.
+* `error`: true if the test expects a hard error. False by default.
+* `success`: true if the test expects a report to be printed with no errors
+  or diagnostics. True by default.
+* `skip`: non-empty if the test should be skipped. The value is a string passed
+  to `t.Skip`.
+* `proxyVersions`: empty if the test should include all `mod/` entries in the
+  proxy, or else a comma-separated list of the modpath@version's it should
+  include.
+
+Test archives have a file named `want`, containing the expected output of the
+test. A test will fail if the actual output differs from `want`.
+
+If the `mod` and `version` parameters are not set, other files will be extracted
+to the temporary directory where `gorelease` runs.
+
+## Populating module contents
+
+When building a test in `testdata/`, there are two ways to populate the module
+directory being tested:
+
+### Option 1: inline
+
+You can inline files in the `.test` folder as described in
+https://pkg.go.dev/golang.org/x/tools/txtar#hdr-Txtar_format. For example,
+
+```
+-- some.file --
+the contents
+of the file
+```
+
+### Option 2: specify an existing file
+
+Often, multiple tests want to share the same setup - the same files. So, users
+can write these common files in `testdata/mod/`, and use one of these files as
+the module directory contents.
+
+To specify a file in `testdata/mod/` to use as the module contents.
+
+## Module format
+
+Tests run with `GOPROXY` set to a local URL that points to a test proxy. The
+test proxy serves modules described by `.txt` files in the `testdata/mod/`
+subdirectory.
+
+Each module is a txtar archive named `$modpath_$version.txt` where `$modpath`
+is the module path (with slashes replaced with underscores) and `$version` is
+the version. If the archive contains a file named `.mod`, that will be used to
+respond to `.mod` requests; otherwise, `go.mod` will be used (`.mod` is only
+necessary for modules that lack `go.mod` files). If the archive contains a
+file named `.info`, that will be used to respond to `.info` requests; otherwise,
+`.info` is synthesized from the version. All other files in the archive are
+packed into a `.zip` file to satisfy `.zip` requests.

+Module example.com/basic tests basic functionality of gorelease.
+It verifies that versions are correctly suggested or verified after
+various changes.
+
+All revisions are stored in the mod directory. The same series of
+changes is made across three major versions, v0, v1, and v2:
+
+vX.0.1 - simple package
+vX.1.0 - compatible change: add a function and a package
+vX.1.1 - internal change: function returns different value
+vX.1.2 - incompatible change: delete a function and a package

+Tests in this directory cover scenarios where errors in a package are fixed.
+
+v1.0.0 is used as the base version for all tests.
+It has an error: the return type of bad.Broken is undefined.
+
+Each test fixes the error and may make other changes (compatible or not).
+Note that fixing a type error in the API appears to be an incompatible change.

+Modules example.com/internalcompat/{a,b} are copies. One could be a fork
+of the other. An external package p exposes a type from a package q
+within the same module.
+
+gorelease should not report differences between these packages. The types
+are distinct, but they correspond (in apidiff terminology), which is the
+important property when considering differences between modules.
+
+There are three use cases to consider:
+
+1. One module substitutes for the other via a `replace` directive.
+   Only the replacement module is used, and the package paths are effectively
+   identical, so the types are not distinct.
+2. One module subsititutes for the other by rewriting `import` statements
+   globally. All references to the original type become references to the
+   new type, so there is no conflict.
+3. One module substitutes for the other by rewriting some `import` statements
+   but not others (for example, those within a specific consumer package).
+   In this case, the types are distinct, and even if there are no changes,
+   the types are not compatible.

+// The txtar command writes or extracts a text-based file archive in the format
+// provided by the golang.org/x/tools/txtar package.
+//
+// The default behavior is to read a comment from stdin and write the archive
+// file containing the recursive contents of the named files and directories,
+// including hidden files, to stdout. Any non-flag arguments to the command name
+// the files and/or directories to include, with the contents of directories
+// included recursively. An empty argument list is equivalent to ".".
+//
+// The --extract (or -x) flag instructs txtar to instead read the archive file
+// from stdin and extract all of its files to corresponding locations relative
+// to the current, writing the archive's comment to stdout.
+//
+// Archive files are by default extracted only to the current directory or its
+// subdirectories. To allow extracting outside the current directory, use the
+// --unsafe flag.
+//
+// Shell variables in paths are expanded (using os.Expand) if the corresponding
+// variable is set in the process environment. When writing an archive, the
+// variables (before expansion) are preserved in the archived paths.

+# Contributing to Go
+
+Go is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+## Filing issues
+
+When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
+
+1.  What version of Go are you using (`go version`)?
+2.  What operating system and processor architecture are you using?
+3.  What did you do?
+4.  What did you expect to see?
+5.  What did you see instead?
+
+General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
+The gophers there will answer or ask you to file an issue if you've tripped over a bug.
+
+## Contributing code
+
+Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
+before sending patches.
+
+Unless otherwise noted, the Go source files are distributed under
+the BSD-style license found in the LICENSE file.

+# Go Sync
+
+[![Go Reference](https://pkg.go.dev/badge/golang.org/x/sync.svg)](https://pkg.go.dev/golang.org/x/sync)
+
+This repository provides Go concurrency primitives in addition to the
+ones provided by the language and "sync" and "sync/atomic" packages.
+
+## Download/Install
+
+The easiest way to install is to run `go get -u golang.org/x/sync`. You can
+also manually git clone the repository to `$GOPATH/src/golang.org/x/sync`.
+
+## Report Issues / Send Patches
+
+This repository uses Gerrit for code changes. To learn how to submit changes to
+this repository, see https://golang.org/doc/contribute.html.
+
+The main issue tracker for the sync repository is located at
+https://github.com/golang/go/issues. Prefix your issue with "x/sync:" in the
+subject line, so it is easy to find.

+# Contributing to Go
+
+Go is an open source project.
+
+It is the work of hundreds of contributors. We appreciate your help!
+
+## Filing issues
+
+When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
+
+1.  What version of Go are you using (`go version`)?
+2.  What operating system and processor architecture are you using?
+3.  What did you do?
+4.  What did you expect to see?
+5.  What did you see instead?
+
+General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
+The gophers there will answer or ask you to file an issue if you've tripped over a bug.
+
+## Contributing code

+# The plan9 package provides access to the raw system call
+# interface of the underlying operating system.  Porting Go to
+# a new architecture/operating system combination requires
+# some manual effort, though there are tools that automate
+# much of the process.  The auto-generated files have names
+# beginning with z.
+#
+# This script runs or (given -n) prints suggested commands to generate z files
+# for the current system.  Running those commands is not automatic.
+# This script is documentation more than anything else.
+#
+# * asm_${GOOS}_${GOARCH}.s
+#
+# This hand-written assembly file implements system call dispatch.
+# There are three entry points:
+#
+# 	func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+# 	func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
+# 	func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+#
+# The first and second are the standard ones; they differ only in
+# how many arguments can be passed to the kernel.
+# The third is for low-level use by the ForkExec wrapper;
+# unlike the first two, it does not call into the scheduler to
+# let it know that a system call is running.
+#
+# * syscall_${GOOS}.go
+#
+# This hand-written Go file implements system calls that need
+# special handling and lists "//sys" comments giving prototypes
+# for ones that can be auto-generated.  Mksyscall reads those
+# comments to generate the stubs.
+#
+# * syscall_${GOOS}_${GOARCH}.go
+#
+# Same as syscall_${GOOS}.go except that it contains code specific
+# to ${GOOS} on one particular architecture.
+#
+# * types_${GOOS}.c
+#
+# This hand-written C file includes standard C headers and then
+# creates typedef or enum names beginning with a dollar sign
+# (use of $ in variable names is a gcc extension).  The hardest
+# part about preparing this file is figuring out which headers to
+# include and which symbols need to be #defined to get the
+# actual data structures that pass through to the kernel system calls.
+# Some C libraries present alternate versions for binary compatibility
+# and translate them on the way in and out of system calls, but
+# there is almost always a #define that can get the real ones.
+# See types_darwin.c and types_linux.c for examples.
+#
+# * zerror_${GOOS}_${GOARCH}.go
+#
+# This machine-generated file defines the system's error numbers,
+# error strings, and signal numbers.  The generator is "mkerrors.sh".
+# Usually no arguments are needed, but mkerrors.sh will pass its
+# arguments on to godefs.

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "linux"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go
+
+### New Build System (currently for `GOOS == "linux"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts/programs cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to a new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
+for the old system). This program takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you may need to update the
+parsing in mksysnum.
+
+### mksyscall.go
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, and then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+and a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include <errno.h>`, and the
+signal numbers and strings are generated from `#include <signal.h>`. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+### internal/mkmerge
+
+This program is used to extract duplicate const, func, and type declarations
+from the generated architecture-specific files listed below, and merge these
+into a common file for each OS.
+
+The merge is performed in the following steps:
+1. Construct the set of common code that is idential in all architecture-specific files.
+2. Write this common code to the merged file.
+3. Remove the common code from all architecture-specific files.
+
+
+## Generated files
+
+### `zerrors_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).

+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`

+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+	* The parameter lists must give a name for each argument.
+	  This includes return parameters.
+	* The parameter lists must give a type for each argument:
+	  the (x, y, z int) shorthand is not allowed.
+	* If the return parameter is an error number, it must be named err.
+	* If go func name needs to be different than its libc name,
+	* or the function is not in libc, name could be specified
+	* at the end, after "=" sign, like
+	  //sys	getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go
+func asyscall(...) (n int, err error) {
+	 // Pointer Creation
+	 r1, e1 := callasyscall(...)
+	 // Type Conversion

+// data can be written to the socket, processed by the kernel, and then read
+// back as hash output or ciphertext.
+//
+// Here is an example of using an AF_ALG socket with SHA1 hashing.
+// The initial socket setup process is as follows:
+//
+//	// Open a socket to perform SHA1 hashing.
+//	fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
+//	addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}

+//	// manually using unix.Syscall.

+//
+// Once a file descriptor has been returned from Accept, it may be used to
+// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
+// may be re-used repeatedly with subsequent Write and Read operations.
+//
+// When hashing a small byte slice or string, a single Write and Read may
+// be used:
+//
+//	// Assume hashfd is already configured using the setup process.
+//	hash := os.NewFile(hashfd, "sha1")
+//	// Hash an input string and read the results. Each Write discards
+//	// previous hash state. Read always reads the current state.
+//	b := make([]byte, 20)
+//	for i := 0; i < 2; i++ {
+//	    io.WriteString(hash, "Hello, world.")
+//	    hash.Read(b)

+//	// 2ae01472317d1935a84797ec1983ae243fc6aa28
+//
+// For hashing larger byte slices, or byte streams such as those read from
+// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
+// the hash digest instead of creating a new one for a given chunk and finalizing it.
+//

+mkwinsyscall generates windows system call bodies
+
+It parses all files specified on command line containing function
+prototypes (like syscall_windows.go) and prints system call bodies
+to standard output.
+
+The prototypes are marked by lines beginning with "//sys" and read
+like func declarations if //sys is replaced by func, but:
+
+  - The parameter lists must give a name for each argument. This
+    includes return parameters.
+
+  - The parameter lists must give a type for each argument:
+    the (x, y, z int) shorthand is not allowed.
+
+  - If the return parameter is an error number, it must be named err.
+
+  - If go func name needs to be different from its winapi dll name,
+    the winapi name could be specified at the end, after "=" sign, like
+    //sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
+
+  - Each function that returns err needs to supply a condition, that
+    return value of winapi will be tested against to detect failure.
+    This would set err to windows "last-error", otherwise it will be nil.
+    The value can be provided at end of //sys declaration, like
+    //sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
+    and is [failretval==0] by default.
+
+  - If the function name ends in a "?", then the function not existing is non-
+    fatal, and an error will be returned instead of panicking.
+
+Usage:
+
+	mkwinsyscall [flags] [path ...]
+
+The flags are:
+
+	-output
+		Specify output file name (outputs to console if blank).
+	-trace
+		Generate print statement after every syscall.

+## ev-signed-file.exe

+This was generated with:
+
+  int main(void)
+  {
+      puts("Hello Gophers!");
+      return 0;
+  }
+
+And then a simple clang/mingw compilation:
+
+  i686-w64-mingw32-gcc -Os -s a.c
+
+After, it was copied to a Windows computer where it was signed with an EV
+certificate using:
+
+  signtool sign /sha1 <ID of certificate> /fd sha256 /tr http://timestamp.digicert.com /td sha256 /d "Go Project EV Signing Test" a.exe

+# Icinga DB
+
+Icinga DB is a set of components for publishing, synchronizing and
+visualizing monitoring data in the Icinga ecosystem, consisting of:
+
+* The Icinga DB daemon, which synchronizes monitoring data between a Redis server and a database
+* Icinga 2 with its [Icinga DB feature](https://icinga.com/docs/icinga-2/latest/doc/14-features/#icinga-db) enabled,
+  responsible for publishing the data to the Redis server, i.e. configuration and its runtime updates, check results,
+  state changes, downtimes, acknowledgements, notifications, and other events such as flapping
+* And Icinga Web with the
+  [Icinga DB Web](https://icinga.com/docs/icinga-db-web) module enabled,
+  which connects to both Redis and the database to display and work with the most up-to-date data

+# Installing Icinga DB
+
+The recommended way to install Icinga DB is to use prebuilt packages for
+all supported platforms from our official release repository.
+Please follow the steps listed for your target operating system,
+which guide you through setting up the repository and installing Icinga DB.
+
+To upgrade an existing Icinga DB installation to a newer version,
+see the [Upgrading](04-Upgrading.md) documentation for the necessary steps.
+
+![Icinga DB Daemon](images/icingadb-daemon.png)
+
+Before installing Icinga DB, make sure you have installed [Icinga 2](https://icinga.com/docs/icinga-2),
+set up a Redis server, and enabled the `icingadb` feature.
+The Icinga 2 installation documentation covers all the necessary steps.
+Additionally, Icinga offers the `icingadb-redis` package for all supported operating systems,
+which ships an up-to-date Redis server version and is pre-configured for the Icinga DB components.
+
+!!! tip
+
+    Although Icinga DB can run anywhere in an Icinga environment,
+    we recommend to install it where the corresponding Icinga 2 node and Redis server is running to
+    keep latency between the components low.
+
+<!-- {% else %} -->
+## Adding Icinga Package Repository
+
+The recommended way to install Icinga DB is to use prebuilt packages from our official release repository.
+
+!!! tip
+
+    If you install Icinga DB on a node that has Icinga 2 or Icinga Web installed via packages,
+    proceed to [installing the Icinga DB package](#installing-icinga-db-web-package) as
+    the repository is already configured.
+
+Here's how to add the official release repository:
+
+<!-- {% if amazon_linux %} -->
+<!-- {% if not icingaDocs %} -->
+### Amazon Linux 2 Repository
+<!-- {% endif %} -->
+!!! info
+
+    A paid repository subscription is required for Amazon Linux 2 repositories. Get more information on
+    [icinga.com/subscription](https://icinga.com/subscription).
+
+    Don't forget to fill in the username and password section with appropriate credentials in the local .repo file.

+<!-- {% if amazon_linux %} -->
+<!-- {% if not icingaDocs %} -->
+#### Amazon Linux 2
+<!-- {% endif %} -->
+```bash
+yum install icingadb
+```
+<!-- {% endif %} -->
+
+<!-- {% if centos %} -->
+<!-- {% if not icingaDocs %} -->
+#### CentOS
+<!-- {% endif %} -->
+!!! info
+
+    Note that installing Icinga DB is only supported on CentOS 7 as CentOS 8 is EOL.
+
+```bash
+yum install icingadb
+```
+<!-- {% endif %} -->
+
+<!-- {% if debian or ubuntu %} -->
+<!-- {% if not icingaDocs %} -->
+#### Debian / Ubuntu
+<!-- {% endif %} -->

+<!-- {% if not icingaDocs %} -->
+#### SLES
+<!-- {% endif %} -->
+```bash
+zypper install icingadb
+```
+<!-- {% endif %} -->
+
+## Setting up the Database
+
+A MySQL (≥5.5), MariaDB (≥10.1), or PostgreSQL (≥9.6) database is required to run Icinga DB.
+Please follow the steps listed for your target database,
+which guide you through setting up the database and user and importing the schema.
+
+![Icinga DB Database](images/icingadb-database.png)
+
+!!! info
+
+    In high availability setups, all Icinga DB instances must write to the same database.
+
+### Setting up a MySQL or MariaDB Database
+
+If you use a version of MySQL < 5.7 or MariaDB < 10.2, the following server options must be set:
+
+```
+innodb_file_format=barracuda
+innodb_file_per_table=1
+innodb_large_prefix=1
+```
+
+Set up a MySQL database for Icinga DB:
+
+```
+# mysql -u root -p
+
+CREATE DATABASE icingadb;
+CREATE USER 'icingadb'@'localhost' IDENTIFIED BY 'CHANGEME';
+GRANT ALL ON icingadb.* TO 'icingadb'@'localhost';
+```
+
+After creating the database, import the Icinga DB schema using the following command:
+
+```
+mysql -u root -p icingadb </usr/share/icingadb/schema/mysql/schema.sql
+```
+
+### Setting up a PostgreSQL Database
+
+Set up a PostgreSQL database for Icinga DB:
+
+```
+# su -l postgres
+
+createuser -P icingadb
+createdb -E UTF8 --locale en_US.UTF-8 -T template0 -O icingadb icingadb
+psql icingadb <<<'CREATE EXTENSION IF NOT EXISTS citext;'
+```
+
+The `CREATE EXTENSION` command requires the `postgresql-contrib` package.
+
+Edit `pg_hba.conf`, insert the following before everything else:
+
+```
+local all icingadb           md5
+host  all icingadb 0.0.0.0/0 md5
+host  all icingadb      ::/0 md5
+```
+
+To apply these changes, run `systemctl reload postgresql`.
+
+After creating the database, import the Icinga DB schema using the following command:
+
+```
+psql -U icingadb icingadb < /usr/share/icingadb/schema/pgsql/schema.sql
+```
+
+## Configuring Icinga DB
+
+Icinga DB installs its configuration file to `/etc/icingadb/config.yml`,
+pre-populating most of the settings for a local setup. Before running Icinga DB,
+adjust the Redis and database credentials and, if necessary, the connection configuration.
+The configuration file explains general settings.
+All available settings can be found under [Configuration](03-Configuration.md).
+
+## Running Icinga DB
+
+The `icingadb` package automatically installs the necessary systemd unit files to run Icinga DB.
+Please run the following command to enable and start its service:
+
+```bash
+systemctl enable --now icingadb
+```
+
+## Installing Icinga DB Web
+
+With Icinga 2, Redis, Icinga DB and the database fully set up, it is now time to install Icinga DB Web,
+which connects to both Redis and the database to display and work with the monitoring data.
+
+![Icinga DB Web](images/icingadb-web.png)
+
+The Icinga DB Web package is also included in the Icinga repository, and since it is already set up,
+you have completed the instructions here and can proceed to
+<!-- {% if amazon_linux %} -->

+| dump-signals      | Dump signals received from Icinga.                                             |
+| heartbeat         | Icinga heartbeats received through Redis.                                      |
+| high-availability | Manages responsibility of Icinga DB instances.                                 |
+| history-sync      | Synchronization of history entries from Redis to MySQL.                        |
+| overdue-sync      | Calculation and synchronization of the overdue status of checkables.           |

+| runtime-updates   | Runtime updates of config objects after the initial config synchronization.    |
+| telemetry         | Reporting of Icinga DB status to Icinga 2 via Redis (for monitoring purposes). |
+
+## Retention
+
+By default, no historical data is deleted, which means that the longer the data is retained,
+the more disk space is required to store it.  History retention is an optional feature that allows to
+limit the number of days that historical data is available for each history category.
+There are separate options for the full history tables used to display history information in the web interface and
+SLA tables which store the minimal information required for SLA reporting,
+allowing to keep this information for longer with a smaller storage footprint.
+
+| Option       | Description                                                                                                                                                                                                   |
+|--------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| history-days | **Optional.** Number of days to retain historical data for all history categories. Use `options` in order to enable retention only for specific categories or to override the retention days configured here. |
+| sla-days     | **Optional.** Number of days to retain historical data for SLA reporting.                                                                                                                                     |
+| options      | **Optional.** Map of history category to number of days to retain its data. Available categories are `acknowledgement`, `comment`, `downtime`, `flapping`, `notification`, `sla` and `state`.                 |
+
+## Appendix
+
+### Duration String
+
+A duration string is a sequence of decimal numbers and a unit suffix, such as `"20s"`.
+Valid units are `"ms"`, `"s"`, `"m"` and `"h"`.

+
+## Upgrading to Icinga DB RC2
+
+Icinga DB RC2 is a complete rewrite compared to RC1. Because of this, a lot has changed in the Redis and database
+schema, which is why they have to be deleted and recreated. The configuration file has changed from `icingadb.ini`
+to `config.yml`. Instead of the INI format, we are now using YAML and have introduced more configuration options. We
+have also changed the packages of `icingadb-redis`, which is why the Redis CLI commands are now prefixed with `icingadb`
+instead of just `icinga`, i.e. the Redis CLI is now accessed via `icingadb-redis-cli`.
+
+Please follow the steps below to upgrade to Icinga DB RC2:
+
+1. Stop Icinga 2 and Icinga DB.
+2. Flush your Redis instances using `icinga-redis-cli flushall` (note the `icinga` prefix as we did not
+   upgrade `icingadb-redis` yet) and stop them afterwards.
+3. Upgrade Icinga 2 to version 2.13.2 or newer.
+4. Remove the `icinga-redis` package where installed as it may conflict with `icingadb-redis`.
+5. Install Icinga DB Redis (`icingadb-redis`) on your primary Icinga 2 nodes to version 6.2.6 or newer.
+6. Upgrade Icinga DB to RC2.
+7. Drop the Icinga DB MySQL database and recreate it using the provided schema.
+8. Start Icinga DB Redis, Icinga 2 and Icinga DB.

+# Distributed Setups
+
+## High Availability
+
+High availability functionality is built directly into Icinga DB and
+can be deployed without additional third-party components.
+
+![Icinga DB HA](images/icingadb-ha.png)
+
+First, you need an Icinga 2 high availability setup with two master nodes, such as described
+[here](https://icinga.com/docs/icinga-2/latest/doc/06-distributed-monitoring#high-availability-master-with-agents).
+
+Each of the master nodes must have the Icinga DB feature enabled and
+have their own dedicated Redis server set up for it, so that each node writes the monitoring data separately.
+The setup steps per node are no different from a single node setup and can be found in the
+[Icinga 2 installation documentation](https://icinga.com/docs/icinga-2/latest/doc/02-installation).
+Each Redis server will always have the complete data available as long as
+its corresponding Icinga 2 master is running and writing to its Redis.
+This is because the Icinga 2 master nodes synchronize their data and events with each other as long as
+they are connected,
+and each takes over the entire configuration in case the other node or their connection to each other fails.
+
+For each Redis server you need to set up its own dedicated Icinga DB instance that connects to it,
+but the Icinga DB instances must write to the same database, which of course can be replicated or a cluster.
+So the steps from the standard
+[Icinga DB installation documentation](https://icinga.com/docs/icinga-db/latest/doc/02-installation)
+can be followed. However, as mentioned, the database only needs to be set up once.
+
+All in all, an Icinga DB HA environment involves setting up two Icinga 2 master nodes, two Redis servers,
+two Icinga DB instances and one database.
+
+Please read the note about the [environment ID](#environment-id),
+which is common to all Icinga DB components and generated by Icinga 2's Icinga DB feature.
+
+There is only one Icinga DB instance at a time,
+which is responsible for performing database operations in the following areas:
+
+* Synchronizing configuration, also across Icinga 2 restarts.
+* Performing configuration runtime updates made via the Icinga 2 API.
+* Updating recent host and service states.
+* Flagging hosts and services that are overdue for updates.
+* Deleting history items that have exceeded their configured retention time.
+
+However, both Icinga DB instances write all events relevant to the history of hosts and services to the database.
+This way, no data is lost if one of the Icinga 2 masters is unavailable or if their connection to each other fails.
+
+Which Icinga DB instance is responsible is determined by a specific database operation that
+can only be performed by one instance first.
+In the case of concurrent operations, simply put, only one wins via a locking mechanism.
+Of course, this is only true if the environment is healthy.
+Icinga DB is not trying to be responsible if its corresponding Redis server is unavailable or
+Icinga 2 is not writing data to Redis.
+If Icinga 2 or Redis become unavailable for more than 60 seconds,
+Icinga DB releases responsibility so the other instance can take over.
+
+## Multiple Environments
+
+Icinga DB supports synchronization of monitoring data from multiple different Icinga environments into
+a single database. This allows Icinga DB Web to provide a centralized view of the data.
+Although everything is prepared in Icinga DB, there is no full support in Icinga DB Web yet.
+As soon as it is ready, the documentation will be adapted and the feature will be explained in more detail.
+
+![Icinga DB Envs](images/icingadb-envs.png)
+
+## Environment ID
+
+!!! important
+
+    Icinga 2 generates a unique environment ID from its CA certificate when it is first started with the
+    Icinga DB feature enabled. The ID is used in all Icinga DB components to separate data from
+    multiple different environments and is written to the file `/var/lib/icinga2/icingadb.env` by Icinga 2.
+
+    It is strictly recommended not to change this ID afterwards, as all data would be resynchronized and
+    the old ones would remain in the database, resulting in duplicate data. As long as the file remains,
+    Icinga 2 will not regenerate the environment ID. This is also true if the CA is changed to avoid duplicate data.
+    Special care should be taken if you add or redeploy the master node(s) and
+    as a result or over time the CA has changed, which would result in a new environment ID.
+    If this is the case, make sure you copy the file between your Icinga 2 masters to get a consistent ID.
+
+    For high-availability setups, it is a good idea to enable the Icinga DB feature on the secondary master after
+    you have successfully connected from/to the primary master so that the certificates are set up properly.
+    The secondary master will then generate the same environment ID since it is working with the same CA certificate.
+
+    In any case make sure that the file `/var/lib/icinga2/icingadb.env` does not change over time and
+    is the same on all Icinga 2 master nodes per environment.

+# Migration from IDO
+
+Migrating from the IDO feature to Icinga DB starts by setting up Icinga DB. To
+do so, please follow the [installation instructions]. The Icinga DB feature can
+be enabled in parallel to the IDO, allowing you to perform the migration while
+the IDO is still running.
+
+After setting up Icinga DB, all Icinga objects and their current state should
+already show up in Icinga DB Web as this information is synced from Icinga 2.
+At this point, the old host and service history is missing in Icinga DB. If it
+is desired to keep it, this information has to be migrated explicitly from the
+old IDO database. To do so, follow the instructions below.
+
+## History
+
+To migrate history data from the [IDO] database, the Icinga DB Migration
+commandline tool is provided. If you have installed Icinga DB from our
+packages, it is automatically installed as well.
+
+### Preparing the Configuration
+
+Please take the [example configuration] as a starting point and copy it to the
+host you will perform the migration on.  The following sections will guide you
+through how to adjust it for your needs.
+
+#### Environment ID
+
+Icinga DB allows writing multiple Icinga environments to the same database.
+Thus, you have to tell the migration tool for which environment you want to
+migrate the history. On each Icinga 2 node that has the Icinga DB feature
+enabled, the environment ID is written to the file
+`/var/lib/icinga2/icingadb.env`. Please use the contents of this file for the
+`env` option in the section `icinga2`.
+
+#### Database Connection
+
+The migration tool needs to access both the IDO and the Icinga DB databases.
+Please specify the connection details in the corresponding `ido` and `icingadb`
+sections of the configuration.
+
+Both the IDO and Icinga DB support MySQL and PostgreSQL. You can migrate from
+and to both types, including from one type to the other.
+
+#### Input Time Range
+
+The migration tool allows you to restrict the time range of the history events
+to be migrated. This is controlled by the options `from` and `to` in the `ido`
+section of the configuration. Both options can be set to Unix timestamps.
+
+It is recommended to set the `to` option to a cutoff time at which the history
+in the Icinga DB database switches from migrated events to events written
+directly by Icinga DB. If you kept running the IDO in parallel to Icinga DB and
+do not do this, there will be duplicate events for the time both were running.
+
+You can query the time of the first history event written by Icinga DB by
+running this query in its database:
+
+```
+SELECT MIN(event_time)/1000 FROM history;
+```
+
+In case you had trouble setting up Icinga DB or this is not the first time you
+are setting up Icinga DB, please make sure to double-check this timestamp and
+adjust it accordingly if it is not what you expect.
+
+!!! tip
+
+    You can convert between Unix timestamps and a human-readable format using the `date` command:
+
+    * Unix timestamp to readable date: `date -d @1667219820`
+    * Current date/time to Unix timestamp: `date +%s`
+    * Specific date/time to Unix timestamp: `date -d '2022-01-01 00:00:00' +%s`
+    * Relative date/time to Unix timestamp: `date -d '-1 year' +%s`
+
+Similarly, you can use `from` to limit how much old history gets migrated.
+
+### Cache Directory
+
+Choose a (not necessarily yet existing) directory for Icinga DB Migration's
+internal cache. If either there isn't much to migrate or the migration
+process won't be interrupted by a reboot (of the machine
+Icinga DB migration/database runs on), `mktemp -d` is enough.
+
+### Run the Migration
+
+To start the actual migration, execute the following command:
+
+```shell
+icingadb-migrate -c icingadb-migration.yml -t ~/icingadb-migration.cache
+```
+
+In case this command was interrupted, you can run it again. It will continue
+where it left off and reuse the cache if it is still present.
+
+!!! tip
+
+    If there is much to migrate, use e.g. tmux to
+    protect yourself against SSH connection losses.
