+# Tests cases autovacuum-2.* test that root pages are allocated

+# autovacuum-2.1.*: Drop the tables that currently exist in the database.
+# autovacuum-2.2.*: Create some tables. Ensure that data pages can be
+#                   moved correctly to make space for new root-pages.
+# autovacuum-2.3.*: Drop one of the tables just created (not the last one),
+#                   and check that one of the other tables is moved to
+#                   the free root-page location.
+# autovacuum-2.4.*: Check that a table can be created correctly when the
+#                   root-page it requires is on the free-list.
+# autovacuum-2.5.*: Check that a table with indices can be dropped. This
+#                   is slightly tricky because dropping one of the
+#                   indices/table btrees could move the root-page of another.
+#                   The code-generation layer of SQLite overcomes this problem
+#                   by dropping the btrees in descending order of root-pages.

+# The following procedure runs with SQLite's IO error simulation 
+# enabled.
+#
+#   1) Start with a reasonably sized database. One that includes the
+#      pending-byte (locking) page.
+#
+#   2) Open a backup process. Set the cache-size for the destination
+#      database to 10 pages only.
+#
+#   3) Step the backup process N times to partially backup the database
+#      file. If an IO error is reported, then the backup process is
+#      concluded with a call to backup_finish().
+#
+#      If an IO error occurs, verify that:
+#
+#      * the call to backup_step() returns an SQLITE_IOERR_XXX error code.
+#
+#      * after the failed call to backup_step() but before the call to
+#        backup_finish() the destination database handle error code and 
+#        error message remain unchanged.
+#
+#      * the call to backup_finish() returns an SQLITE_IOERR_XXX error code.
+#
+#      * following the call to backup_finish(), the destination database
+#        handle has been populated with an error code and error message.
+#
+#   4) Write to the database via the source database connection. Check 
+#      that:
+#
+#      * If an IO error occurs while writing the source database, the
+#        write operation should report an IO error. The backup should 
+#        proceed as normal.
+#
+#      * If an IO error occurs while updating the backup, the write 
+#        operation should proceed normally. The error should be reported
+#        from the next call to backup_step() (in step 5 of this test
+#        procedure).
+#
+#   5) Step the backup process to finish the backup. If an IO error is 
+#      reported, then the backup process is concluded with a call to 
+#      backup_finish().
+#
+#      Test that if an IO error occurs, or if one occurred while updating
+#      the backup database during step 4, then the conditions listed
+#      under step 3 are all true.
+#
+#   6) Finish the backup process.
+#
+#   * If the backup succeeds (backup_finish() returns SQLITE_OK), then
+#     the contents of the backup database should match that of the
+#     source database.
+#
+#   * If the backup fails (backup_finish() returns other than SQLITE_OK), 
+#     then the contents of the backup database should be as they were 
+#     before the operation was started.
+#
+# The following factors are varied:
+#
+#   * Destination database is initially larger than the source database, OR
+#   * Destination database is initially smaller than the source database.
+#
+#   * IO errors are transient, OR
+#   * IO errors are persistent.
+#
+#   * Destination page-size is smaller than the source.

+#--------------------------------------------------------------------------
+# OVERVIEW
+#
+#   This test file attempts to verify that SQLite does not read past the 
+#   end of any in-memory buffers as a result of corrupted database page 
+#   images. Usually this happens because a field within a database page
+#   that contains an offset to some other structure within the same page
+#   is set to too large a value. A database page contains the following
+#   such fields:
+#
+#     1. The page header field that contains the offset to the first 
+#        free block of space.
+#
+#     2. The first two bytes of all but the last free block on the free-block
+#        list (the offset to the next free block).
+#
+#     3. The page header field containing the number of cells on the page
+#        (implicitly defines the offset to the final element in the cell offset
+#        array, which could potentially be off the end of the page).
+#
+#     4. The page header field containing the offset to the start of the cell
+#        content area.
+#
+#     5. The contents of the cell offset array.
+#
+#     6. The first few bytes of each cell determine the size of the cell
+#        stored within the page, and hence the offset to the final byte of
+#        the cell.
+#
+#   If any of the above fields are set to too large a value, then a buffer
+#   overread may occur. This test script creates and operates on various
+#   strategically corrupted database files to attempt to provoke such buffer
+#   overreads.
+#
+#   Very often, a buffer overread passes unnoticed, particularly in workstation
+#   environments. For this reason, this test script should be run using valgrind
+#   (or similar) in order to verify that no overreads occur.
+#
+# TEST PLAN
+# 
+#   Test cases corruptD-1.* are white-box tests. They attempt to corrupt
+#   one of the above fields, then exercise each part of the code in btree.c
+#   that uses said field.
+#   
+#   Offset variables 1, 2, 3 and 4 are all checked to make sure they
+#   will not result in buffer overruns as part of page initialization in
+#   sqlite3BtreeInitPage(). Offsets 5 and 6 cannot be tested as part of
+#   page initialization, as trying to do so causes a performance hit.

+** This program tests the ability of SQLite database to recover from a crash.

+**
+** The main process first constructs a test database, then starts creating
+** subprocesses that write to that database.  Each subprocess is killed off,
+** without a chance to clean up its database connection, after a random
+** delay.  This killing of the subprocesses simulates a crash or power
+** failure.  The next subprocess to open the database should rollback
+** whatever operation was in process at the time of the simulated crash.
+**
+** If any problems are encountered, an error is reported and the test stops.
+** If no problems are seen after a large number of tests, we assume that
+** the rollback mechanism is working.

+*************************************************************************
+**
+** This program is designed for fuzz-testing SQLite database files using
+** the -fsanitize=fuzzer option of clang.
+**
+** The -fsanitize=fuzzer option causes a main() to be inserted automatically.
+** That main() invokes LLVMFuzzerTestOneInput(D,S) to be invoked repeatedly.
+** Each D is a fuzzed database file.  The code in this file runs various
+** SQL statements against that database, trying to provoke a failure.
+**
+** For best results the seed database files should have these tables:
+**
+**   Table "t1" with columns "a" and "b"
+**   Tables "t2" and "t3 with the same number of compatible columns
+**       "t3" should have a column names "x"
+**   Table "t4" with a column "x" that is compatible with t3.x.
+**
+** Any of these tables can be virtual tables, for example FTS or RTree tables.
+**
+** To run this test:
+**
+**     mkdir dir
+**     cp dbfuzz2-seed*.db dir

+# This file implements regression tests for SQLite library.  The

+# ticket #842.
+#
+# Ticket #842 was a database corruption problem caused by a DELETE that
+# removed an index entry by not the main table entry.  To recreate the
+# problem do this:
+#
+#   (1) Create a table with an index.  Insert some data into that table.
+#   (2) Start a query on the table but do not complete the query.
+#   (3) Try to delete a single entry from the table.
+#
+# Step 3 will fail because there is still a read cursor on the table.
+# But the database is corrupted by the DELETE.  It turns out that the
+# index entry was deleted first, before the table entry.  And the index
+# delete worked.  Thus an entry was deleted from the index but not from
+# the table.
+#
+# The solution to the problem was to detect that the table is locked
+# before the index entry is deleted.

+# te_* commands:
+#
+#
+#   te_read_sql DB SELECT-STATEMENT
+#   te_read_tbl DB TABLENAME
+#
+# These two commands are used to read a dataset from the database. A dataset
+# consists of N rows of M named columns of values each, where each value has a
+# type (null, integer, real, text or blob) and a value within the types domain.
+# The tcl format for a "dataset" is a list of two elements:
+#
+#   * A list of the column names.
+#   * A list of data rows. Each row is itself a list, where each element is
+#     the contents of a column of the row. Each of these is a list of two
+#     elements, the type name and the actual value.
+#
+# For example, the contents of table [t1] as a dataset is:
+#
+#   CREATE TABLE t1(a, b);
+#   INSERT INTO t1 VALUES('abc', NULL);
+#   INSERT INTO t1 VALUES(43.1, 22);
+#
+#   {a b} {{{TEXT abc} {NULL {}}} {{REAL 43.1} {INTEGER 22}}}
+#
+# The [te_read_tbl] command returns a dataset read from a table. The
+# [te_read_sql] returns the dataset that results from executing a SELECT
+# command.
+#
+#
+#   te_tbljoin ?SWITCHES? LHS-TABLE RHS-TABLE
+#   te_join ?SWITCHES? LHS-DATASET RHS-DATASET
+#
+# This command joins the two datasets and returns the resulting dataset. If 
+# there are no switches specified, then the results is the cartesian product
+# of the two inputs.  The [te_tbljoin] command reads the left and right-hand
+# datasets from the specified tables. The [te_join] command is passed the
+# datasets directly.
+#
+# Optional switches are as follows:
+#
+#   -on SCRIPT
+#   -using COLUMN-LIST
+#   -left
+#
+# The -on option specifies a tcl script that is executed for each row in the
+# cartesian product of the two datasets. The script has 4 arguments appended
+# to it, in the following order:
+#
+#   * The list of column-names from the left-hand dataset.
+#   * A single row from the left-hand dataset (one "data row" list as 
+#     described above.
+#   * The list of column-names from the right-hand dataset.
+#   * A single row from the right-hand dataset.
+#
+# The script must return a boolean value - true if the combination of rows
+# should be included in the output dataset, or false otherwise.
+#
+# The -using option specifies a list of the columns from the right-hand
+# dataset that should be omitted from the output dataset.
+#
+# If the -left option is present, the join is done LEFT JOIN style. 
+# Specifically, an extra row is inserted if after the -on script is run there
+# exist rows in the left-hand dataset that have no corresponding rows in
+# the output. See the implementation for more specific comments.
+#
+#
+#   te_equals ?SWITCHES? COLNAME1 COLNAME2 <-on script args>

+# Test structure:
+#
+# fkey2-1.*: Simple tests to check that immediate and deferred foreign key 
+#            constraints work when not inside a transaction.
+#            
+# fkey2-2.*: Tests to verify that deferred foreign keys work inside
+#            explicit transactions (i.e that processing really is deferred).
+#
+# fkey2-3.*: Tests that a statement transaction is rolled back if an
+#            immediate foreign key constraint is violated.
+#
+# fkey2-4.*: Test that FK actions may recurse even when recursive triggers
+#            are disabled.
+#
+# fkey2-5.*: Check that if foreign-keys are enabled, it is not possible
+#            to write to an FK column using the incremental blob API.
+#
+# fkey2-6.*: Test that FK processing is automatically disabled when 
+#            running VACUUM.
+#
+# fkey2-7.*: Test using an IPK as the key in the child (referencing) table.
+#
+# fkey2-8.*: Test that enabling/disabling foreign key support while a 
+#            transaction is active is not possible.
+#
+# fkey2-9.*: Test SET DEFAULT actions.
+#
+# fkey2-10.*: Test errors.
+#
+# fkey2-11.*: Test CASCADE actions.
+#
+# fkey2-12.*: Test RESTRICT actions.
+#
+# fkey2-13.*: Test that FK processing is performed when a row is REPLACED by
+#             an UPDATE or INSERT statement.
+#
+# fkey2-14.*: Test the ALTER TABLE and DROP TABLE commands.
+#
+# fkey2-15.*: Test that if there are no (known) outstanding foreign key 
+#             constraint violations in the database, inserting into a parent
+#             table or deleting from a child table does not cause SQLite
+#             to check if this has repaired an outstanding violation.
+#
+# fkey2-16.*: Test that rows that refer to themselves may be inserted, 
+#             updated and deleted.
+#
+# fkey2-17.*: Test that the "count_changes" pragma does not interfere with
+#             FK constraint processing.
+# 
+# fkey2-18.*: Test that the authorization callback is invoked when processing
+#             FK constraints.
+#
+# fkey2-20.*: Test that ON CONFLICT clauses specified as part of statements
+#             do not affect the operation of FK constraints.
+#
+# fkey2-genfkey.*: Tests that were used with the shell tool .genfkey
+#            command. Recycled to test the built-in implementation.
+#
+# fkey2-dd08e5.*:  Tests to verify that ticket dd08e5a988d00decc4a543daa8d
+#                  has been fixed.

+# Test overview:
+# 
+#   The tests in this file are pseudo-randomly generated. They test
+#   the fts3 match expression parser via the test interface
+#   SQL function "fts3_exprtest" (see comments in fts3_expr.c).
+#
+#   Each test case works as follows:
+#   
+#     1. A random expression tree is generated using proc [random_expr_tree].
+#     2. The expression tree is converted to the text of an equivalent
+#        fts3 expression using proc [tree_to_expr].
+#     3. The test SQL function "fts3_exprtest" is used to parse the 
+#        expression text generated in step (2), returning a parsed expression
+#        tree.
+#     4. Test that the tree returned in step (3) matches that generated in 
+#        step (1).
+#
+#   In step (2), 4 different fts3 expressions are created from each 
+#   expression tree by varying the following boolean properties:
+#
+#     * Whether or not superflous parenthesis are included. i.e. if
+#       "a OR b AND (c OR d)" or "a OR (b AND (c OR d))" is generated.
+#
+#     * Whether or not explict AND operators are used. i.e. if
+#     "a OR b AND c" or "a OR b c" is generated.

+# Proc [do_matchinfo_test] is used to test the FTSX matchinfo() function.
+#
+# The first argument - $tn - is a test identifier. This may be either a
+# full identifier (i.e. "fts3matchinfo-1.1") or, if global var $testprefix
+# is set, just the numeric component (i.e. "1.1").
+#
+# The second argument is the name of an FTSX table. The third is the 
+# full text of a WHERE/MATCH expression to query the table for 
+# (i.e. "t1 MATCH 'abc'"). The final argument - $results - should be a
+# key-value list (serialized array) with matchinfo() format specifiers
+# as keys, and the results of executing the statement:
+#
+#   SELECT matchinfo($tbl, '$key') FROM $tbl WHERE $expr
+#
+# For example:
+#
+#   CREATE VIRTUAL TABLE t1 USING fts4;
+#   INSERT INTO t1 VALUES('abc');
+#   INSERT INTO t1 VALUES('def');
+#   INSERT INTO t1 VALUES('abc abc');
+#
+#   do_matchinfo_test 1.1 t1 "t1 MATCH 'abc'" {
+#     n {3 3}
+#     p {1 1}
+#     c {1 1}
+#     x {{1 3 2} {2 3 2}}
+#   }
+#
+# If the $results list contains keys mapped to "-" instead of a matchinfo()

+    This specification defines Cascading Style Sheets, level 2 (CSS2). CSS2 is a style sheet language that allows authors and users to attach style (e.g., fonts, spacing, and aural cues) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS2 simplifies Web authoring and site maintenance.
+
+    CSS2 builds on CSS1 (see [CSS1]) and, with very few exceptions, all valid CSS1 style sheets are valid CSS2 style sheets. CSS2 supports media-specific style sheets so that authors may tailor the presentation of their documents to visual browsers, aural devices, printers, braille devices, handheld devices, etc. This specification also supports content positioning, downloadable fonts, table layout, features for internationalization, automatic counters and numbering, and some properties related to user interface.

+# Brute force (random data) tests for FTS3.
+#
+
+#-------------------------------------------------------------------------
+#
+# The FTS3 tests implemented in this file focus on testing that FTS3
+# returns the correct set of documents for various types of full-text
+# query. This is done using pseudo-randomly generated data and queries.
+# The expected result of each query is calculated using Tcl code.
+#
+#   1. The database is initialized to contain a single table with three
+#      columns. 100 rows are inserted into the table. Each of the three
+#      values in each row is a document consisting of between 0 and 100
+#      terms. Terms are selected from a vocabulary of $G(nVocab) terms.
+#
+#   2. The following is performed 100 times:
+#
+#      a. A row is inserted into the database. The row contents are 
+#         generated as in step 1. The docid is a pseudo-randomly selected
+#         value between 0 and 1000000.
+# 
+#      b. A psuedo-randomly selected row is updated. One of its columns is
+#         set to contain a new document generated in the same way as the
+#         documents in step 1.
+# 
+#      c. A psuedo-randomly selected row is deleted.
+# 
+#      d. For each of several types of fts3 queries, 10 SELECT queries
+#         of the form:
+# 
+#           SELECT docid FROM <tbl> WHERE <tbl> MATCH '<query>'
+# 
+#         are evaluated. The results are compared to those calculated by
+#         Tcl code in this file. The patterns used for the different query
+#         types are:
+# 
+#           1.  query = <term>
+#           2.  query = <prefix>
+#           3.  query = "<term> <term>"
+#           4.  query = "<term> <term> <term>"
+#           5.  query = "<prefix> <prefix> <prefix>"
+#           6.  query = <term> NEAR <term>
+#           7.  query = <term> NEAR/11 <term> NEAR/11 <term>
+#           8.  query = <term> OR <term>
+#           9.  query = <term> NOT <term>
+#           10. query = <term> AND <term>
+#           11. query = <term> NEAR <term> OR <term> NEAR <term>
+#           12. query = <term> NEAR <term> NOT <term> NEAR <term>
+#           13. query = <term> NEAR <term> AND <term> NEAR <term>
+# 
+#         where <term> is a term psuedo-randomly selected from the vocabulary
+#         and prefix is the first 2 characters of such a term followed by
+#         a "*" character.
+#     
+#      Every second iteration, steps (a) through (d) above are performed
+#      within a single transaction. This forces the queries in (d) to
+#      read data from both the database and the in-memory hash table
+#      that caches the full-text index entries created by steps (a), (b)
+#      and (c) until the transaction is committed.
+#
+# The procedure above is run 5 times, using advisory fts3 node sizes of 50,
+# 500, 1000 and 2000 bytes.
+#
+# After the test using an advisory node-size of 50, an OOM test is run using
+# the database. This test is similar to step (d) above, except that it tests
+# the effects of transient and persistent OOM conditions encountered while
+# executing each query.

+#   6.* - Test the effects of messing with the schema of table xxx after

+#   
+#   7.* - Test that if content=xxx is specified and table xxx does not

+#         SELECT statements.
+#
+#   8.* - Test that if the content=xxx and prefix options are used together,

+#   9.* - Test using content=xxx where xxx is a virtual table.
+#

+*************************************************************************
+**
+** This is a utility program designed to aid running regressions tests on
+** the SQLite library using data from external fuzzers.
+**
+** This program reads content from an SQLite database file with the following
+** schema:
+**
+**     CREATE TABLE db(
+**       dbid INTEGER PRIMARY KEY, -- database id
+**       dbcontent BLOB            -- database disk file image
+**     );
+**     CREATE TABLE xsql(
+**       sqlid INTEGER PRIMARY KEY,   -- SQL script id
+**       sqltext TEXT                 -- Text of SQL statements to run
+**     );
+**     CREATE TABLE IF NOT EXISTS readme(
+**       msg TEXT -- Human-readable description of this test collection
+**     );
+**
+** For each database file in the DB table, the SQL text in the XSQL table
+** is run against that database.  All README.MSG values are printed prior
+** to the start of the test (unless the --quiet option is used).  If the
+** DB table is empty, then all entries in XSQL are run against an empty
+** in-memory database.
+**
+** This program is looking for crashes, assertion faults, and/or memory leaks.
+** No attempt is made to verify the output.  The assumption is that either all
+** of the database files or all of the SQL statements are malformed inputs,
+** generated by a fuzzer, that need to be checked to make sure they do not
+** present a security risk.
+**
+** This program also includes some command-line options to help with 
+** creation and maintenance of the source content database.  The command
+**
+**     ./fuzzcheck database.db --load-sql FILE...
+**
+** Loads all FILE... arguments into the XSQL table.  The --load-db option
+** works the same but loads the files into the DB table.  The -m option can
+** be used to initialize the README table.  The "database.db" file is created
+** if it does not previously exist.  Example:
+**
+**     ./fuzzcheck new.db --load-sql *.sql
+**     ./fuzzcheck new.db --load-db *.db
+**     ./fuzzcheck new.db -m 'New test cases'
+**
+** The three commands above will create the "new.db" file and initialize all
+** tables.  Then do "./fuzzcheck new.db" to run the tests.
+**
+** DEBUGGING HINTS:
+**
+** If fuzzcheck does crash, it can be run in the debugger and the content
+** of the global variable g.zTextName[] will identify the specific XSQL and
+** DB values that were running when the crash occurred.
+**
+** DBSQLFUZZ: (Added 2020-02-25)
+**
+** The dbsqlfuzz fuzzer includes both a database file and SQL to run against
+** that database in its input.  This utility can now process dbsqlfuzz
+** input files.  Load such files using the "--load-dbsql FILE ..." command-line
+** option.
+**
+** Dbsqlfuzz inputs are ordinary text.  The first part of the file is text
+** that describes the content of the database (using a lot of hexadecimal),
+** then there is a divider line followed by the SQL to run against the
+** database.  Because they are ordinary text, dbsqlfuzz inputs are stored
+** in the XSQL table, as if they were ordinary SQL inputs.  The isDbSql()
+** function can look at a text string and determine whether or not it is
+** a valid dbsqlfuzz input.

+#         statements with no WHERE clause.
+# 4.2.* - Check that the update-hook is invoked for rows modified by trigger
+#         bodies. Also that the database name is correctly reported when 
+#         an attached database is modified.
+# 4.3.* - Do some sorting, grouping, compound queries, population and 
+#         depopulation of indices, to make sure the update-hook is not 
+#         invoked incorrectly.

+# This file implements tests for JOINs.
+#
+# The test case output is all generated by PostgreSQL 14.  This test module
+# was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.

+# This file implements tests for JOINs.
+#
+# The test case output is all generated by PostgreSQL 14.  This test module
+# was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.

+# TESTRUNNER: slow
+#
+# This file implements tests for JOINs that use Bloom filters.
+#
+# The test case output is (mostly) all generated by PostgreSQL 14.  This
+# test module was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.
+#
+# A few extra tests that were not generated from postgresql output are
+# added at the end.

+# This file implements tests for JOINs that use Bloom filters.
+#
+# The test case output is (mostly) all generated by PostgreSQL 14.  This
+# test module was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.

+#
+# This file implements tests for JOINs
+#
+# The test case output is (mostly) all generated by PostgreSQL 14.  This
+# test module was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.
+#
+# A few extra tests that were not generated from postgresql output are
+# added at the end.

+# The tests in this file check that the following two bugs (both now fixed)
+# do not reappear.
+#
+# jrnlmode2-1.*: Demonstrate bug #3745:
+#
+#     In persistent journal mode, if:
+#
+#       * There is a persistent journal in the file-system, AND
+#       * there exists a connection with a shared lock on the db file, 
+#
+#     then a second connection cannot open a read-transaction on the database.
+#     The reason is because while determining that the persistent-journal is
+#     not a hot-journal, SQLite currently grabs an exclusive lock on the
+#     database file. If this fails because another connection has a shared
+#     lock, then SQLITE_BUSY is returned to the user.  
+#
+# jrnlmode2-2.*: Demonstrate bug #3751:
+#
+#     If a connection is opened in SQLITE_OPEN_READONLY mode, the underlying
+#     unix file descriptor on the database file is opened in O_RDONLY mode.
+#
+#     When SQLite queries the database file for the schema in order to compile
+#     the SELECT statement, it sees the empty journal in the file system, it
+#     attempts to obtain an exclusive lock on the database file (this is a
+#     bug). The attempt to obtain an exclusive (write) lock on a read-only file
+#     fails at the OS level. Under unix, fcntl() reports an EBADF - "Bad file
+#     descriptor" - error.

+**
+** The author disclaims copyright to this source code.  In place of
+** a legal notice, here is a blessing:
+**
+**    May you do good and not evil.

+*************************************************************************
+**
+** This file implements "key-value" performance test for SQLite.  The
+** purpose is to compare the speed of SQLite for accessing large BLOBs
+** versus reading those same BLOB values out of individual files in the
+** filesystem.
+**
+** Run "kvtest" with no arguments for on-line help, or see comments below.
+**
+** HOW TO COMPILE:
+**
+** (1) Gather this source file and a recent SQLite3 amalgamation with its
+**     header into the working directory.  You should have:
+**
+**          kvtest.c       >--- this file
+**          sqlite3.c      \___ SQLite
+**          sqlite3.h      /    amlagamation & header
+**
+** (2) Run you compiler against the two C source code files.
+**
+**    (a) On linux or mac:
+**
+**        OPTS="-DSQLITE_THREADSAFE=0 -DSQLITE_OMIT_LOAD_EXTENSION"
+**        gcc -Os -I. $OPTS kvtest.c sqlite3.c -o kvtest
+**
+**             The $OPTS options can be omitted.  The $OPTS merely omit
+**             the need to link against -ldl and -lpthread, or whatever
+**             the equivalent libraries are called on your system.
+**
+**    (b) Windows with MSVC:
+**
+**        cl -I. kvtest.c sqlite3.c
+**
+** USAGE:
+**
+** (1) Create a test database by running "kvtest init" with appropriate
+**     options.  See the help message for available options.
+**
+** (2) Construct the corresponding pile-of-files database on disk using
+**     the "kvtest export" command.
+**
+** (3) Run tests using "kvtest run" against either the SQLite database or
+**     the pile-of-files database and with appropriate options.
+**
+** For example:
+**
+**       ./kvtest init x1.db --count 100000 --size 10000
+**       mkdir x1
+**       ./kvtest export x1.db x1
+**       ./kvtest run x1.db --count 10000 --max-id 1000000
+**       ./kvtest run x1 --count 10000 --max-id 1000000
+*/
+static const char zHelp[] = 
+"Usage: kvtest COMMAND ARGS...\n"
+"\n"
+"   kvtest init DBFILE --count N --size M --pagesize X\n"
+"\n"

+# NOTES ON RECOVERING FROM A MALLOC FAILURE
+# 
+# The tests in this file test the behaviours described in the following
+# paragraphs. These tests test the behaviour of the system when malloc() fails
+# inside of a call to _prepare(), _step(), _finalize() or _reset(). The
+# handling of malloc() failures within ancillary procedures is tested
+# elsewhere.
+#
+# Overview:
+#
+# Executing a statement is done in three stages (prepare, step and finalize). A
+# malloc() failure may occur within any stage. If a memory allocation fails
+# during statement preparation, no statement handle is returned. From the users
+# point of view the system state is as if _prepare() had never been called.
+#
+# If the memory allocation fails during the _step() or _finalize() calls, then
+# the database may be left in one of two states (after finalize() has been
+# called):
+#
+#     * As if the neither _step() nor _finalize() had ever been called on
+#       the statement handle (i.e. any changes made by the statement are
+#       rolled back).
+#     * The current transaction may be rolled back. In this case a hot-journal
+#       may or may not actually be present in the filesystem.
+#
+# The caller can tell the difference between these two scenarios by invoking
+# _get_autocommit().
+#
+#
+# Handling of sqlite3_reset():
+#
+# If a malloc() fails while executing an sqlite3_reset() call, this is handled
+# in the same way as a failure within _finalize(). The statement handle
+# is not deleted and must be passed to _finalize() for resource deallocation.
+# Attempting to _step() or _reset() the statement after a failed _reset() will
+# always return SQLITE_NOMEM.
+#
+#
+# Other active SQL statements:
+#
+# The effect of a malloc failure on concurrently executing SQL statements,
+# particularly when the statement is executing with READ_UNCOMMITTED set and
+# the malloc() failure mandates statement rollback only. Currently, if
+# transaction rollback is required, all other vdbe's are aborted.
+#
+#     Non-transient mallocs in btree.c:
+#         * The Btree structure itself
+#         * Each BtCursor structure
+#
+#     Mallocs in pager.c:
+#         readMasterJournal()  - Space to read the master journal name
+#         pager_delmaster()    - Space for the entire master journal file
+#
+#         sqlite3pager_open()  - The pager structure itself
+#         sqlite3_pagerget()   - Space for a new page
+#         pager_open_journal() - Pager.aInJournal[] bitmap
+#         sqlite3pager_write() - For in-memory databases only: history page and
+#                                statement history page.
+#         pager_stmt_begin()   - Pager.aInStmt[] bitmap
+#
+# None of the above are a huge problem. The most troublesome failures are the
+# transient malloc() calls in btree.c, which can occur during the tree-balance
+# operation. This means the tree being balanced will be internally inconsistent
+# after the malloc() fails. To avoid the corrupt tree being read by a
+# READ_UNCOMMITTED query, we have to make sure the transaction or statement
+# rollback occurs before sqlite3_step() returns, not during a subsequent
+# sqlite3_finalize().

+#--------------------------------------------------------------------------
+# NOTES ON TEST IMPLEMENTATION
+#
+# The tests in this file are implemented differently from those in other
+# files. Instead, tests are specified using three primitives: SQL, PREP and
+# TEST. Each primitive has a single argument. Primitives are processed in
+# the order they are specified in the file.
+#
+# A TEST primitive specifies a TCL script as its argument. When a TEST
+# directive is encountered the Tcl script is evaluated. Usually, this Tcl
+# script contains one or more calls to [do_test].
+#
+# A PREP primitive specifies an SQL script as its argument. When a PREP
+# directive is encountered the SQL is evaluated using database connection
+# [db].
+#
+# The SQL primitives are where the action happens. An SQL primitive must
+# contain a single, valid SQL statement as its argument. When an SQL
+# primitive is encountered, it is evaluated one or more times to test the
+# behaviour of the system when malloc() fails during preparation or
+# execution of said statement. The Nth time the statement is executed,
+# the Nth malloc is said to fail. The statement is executed until it
+# succeeds, i.e. (M+1) times, where M is the number of mallocs() required
+# to prepare and execute the statement.
+#
+# Each time an SQL statement fails, the driver program (see proc [run_test]
+# below) figures out if a transaction has been automatically rolled back.
+# If not, it executes any TEST block immediately proceeding the SQL
+# statement, then reexecutes the SQL statement with the next value of N.
+#
+# If a transaction has been automatically rolled back, then the driver
+# program executes all the SQL specified as part of SQL or PREP primitives
+# between the current SQL statement and the most recent "BEGIN". Any 
+# TEST block immediately proceeding the SQL statement is evaluated, and
+# then the SQL statement reexecuted with the incremented N value.
+#
+# That make any sense? If not, read the code in [run_test] and it might.
+#
+# Extra restriction imposed by the implementation:
+#
+# * If a PREP block starts a transaction, it must finish it.
+# * A PREP block may not close a transaction it did not start.
+#
+#--------------------------------------------------------------------------
+
+
+# These procs are used to build up a "program" in global variable
+# ::run_test_script. At the end of this file, the proc [run_test] is used
+# to execute the program (and all test cases contained therein).

+#
+# A "configuration" is a set of options passed to [./configure] and [make]
+# to build the SQLite library in a particular fashion. A "platform" is a

+# that the tests will be run on as part of the release procedure. Each 
+# "test" is a combination of a configuration and a makefile target (e.g.
+# "fulltest"). The program may be invoked as follows:
+#
+set USAGE {
+$argv0 script ?-msvc? CONFIGURATION TARGET
+    Given a configuration and make target, return a bash (or, if -msvc
+    is specified, batch) script to execute the test. The first argument
+    passed to the script must be a directory containing SQLite source code.
+
+$argv0 configurations
+    List available configurations.
+
+$argv0 platforms
+    List available platforms.
+
+$argv0 tests ?-nodebug? PLATFORM
+    List tests in a specified platform. If the -nodebug switch is

+** The author disclaims copyright to this source code.  In place of
+** a legal notice, here is a blessing:
+**
+**    May you do good and not evil.
+**    May you find forgiveness for yourself and forgive others.
+**    May you share freely, never taking more than you give.
+**
+*************************************************************************
+**
+** This file implements a program used for fuzz-testing the session
+** module.
+**
+** Usage:
+**
+**      sessionfuzz setup         -- Generate starter test cases
+**      sessionfuzz run FILE ...  -- Run a test fuzz on FILE
+**      sesssiofuzz run SQLAR ... -- Run all test cases in the SQL Archive
+**
+** Compiling:
+**
+**    (1) Have a version of SQLite that supports SQLITE_ENABLE_MEMDB
+**        in the local directory.
+**    (2) Run:
+**
+**          gcc -Wall -O3 -o sessionfuzz sessionfuzz.c -lz
+**
+** Use with AFL (American Fuzzy Lop - http://lcamtuf.coredump.cx/afl/)
+**
+**    (1) ./afl-gcc -O3 -o sessionfuzz sessionfuzz.c -lz
+**    (2) mkdir session-init session-run session-cases
+**    (3) cd session-init; ../sessionfuzz setup; cd ..
+**    (4) ./afl -i session-init -o session-run -- ./sessionfuzz run @@
+**    ... let the previous step run for a while.  Weeks, maybe.
+**    (5) ./afl-cmin -i session-run -o session-cases
+**
+** The afl-cmin command on step (5) writes a minimal set of test cases
+** for coverage into the session-cases directory.  Gather the cases written
+** there into an SQL Archive using a command like this:
+**
+**     sqlite3 session-cases.db -Ac session-cases
+**
+** Then repeat the test using:
+**
+**     ./sessionfuzz run session-cases.db

+# This file implements tests of the "skip-scan" query strategy. In 
+# particular, this file verifies that use of all columns of an index
+# is always preferred over the use of a skip-scan on some columns of
+# the same index.  Because of difficulties in scoring a skip-scan,
+# the skip-scan can sometimes come out with a lower raw score when
+# using STAT4.  But the query planner should detect this and use the
+# full index rather than the skip-scan.

+#   + When deleting rows that span overflow pages. This is faster

+# the connection issues a ROLLBACK immediately to abandon the current
+# transaction.
+#
+# If everything is working correctly, the "SELECT count(*)" statements 
+# should never return a value other than 0. The "INSERT" statement 
+# executed by the writer adds a row with "b IS NULL" to the table, but
+# the subsequent UPDATE statement sets its "b" value to an integer
+# immediately afterwards.
+#
+# However, before the race-condition was fixed, if the reader's SELECT
+# statement hit an error (say an SQLITE_LOCKED) at the same time as the
+# writer was executing the UPDATE statement, then it could incorrectly
+# rollback the statement-transaction belonging to the UPDATE statement.
+# The UPDATE statement would still be reported as successful to the user,
+# but it would have no effect on the database contents.
+# 
+# Note that it has so far only proved possible to hit this race-condition
+# when using an ATTACHed database. There doesn't seem to be any reason
+# for this, other than that operating on an ATTACHed database means there
+# are a few more mutex grabs and releases during the window of time open
+# for the race-condition. Maybe this encourages the scheduler to context
+# switch or something...

+# This file implements regression tests for SQLite library.

+# This file implements tests to verify that ticket [b72787b1a7] has been

+#
+#     The sqlite3ExpirePreparedStatements routine marks all statements
+#     as expired. This includes statements that are not expired.
+#
+#     Steps to reproduce:
+#
+#        * Prepare a statement (A)
+#        * Alter the schema to invalidate cookie in A
+#        * Prepare a statement (B)
+#        * Run B and have A run as part of B
+#        * A will find a bad cookie and cause *all* statements
+#          to be expired including the currently running B by calling
+#          sqlite3ExpirePreparedStatements
+#        * When control returns to B it will then abort 
+#
+#     The bug is that sqlite3ExpirePreparedStatements expires all statements.
+#     Note that B was prepared after the schema change and hence is perfectly
+#     valid and then is marked as expired while running.

+# The problem in ticket #1433 was that the dependencies on the right-hand

+#
+#         t1.x IN (1,t2.b,3)
+#
+# the optimizer was missing the fact that the right-hand side of the IN

+# Expr.pRight field rather than Expr.pList and Expr.pSelect.  
+#
+# Such a bug could be verifed using a less elaborate test case.  But
+# this test case (from the original bug poster) exercises so many different
+# parts of the system all at once, that it seemed like a good one to
+# include in the test suite.

+# NOTE:  Yes, in spite of the name of this file (tkt1443.test) this

+# This file implements tests to verify that table column values
+# are pulled out of the database correctly.
+#
+# Long ago, the OP_Column opcode was sufficient to pull out the
+# value of a table column.  But then we added the ALTER TABLE ADD COLUMN
+# feature.  An added column might not actually exist in every row,
+# and so the OP_Column opcode has to contain a default value.  Later
+# still we added a feature whereby a REAL value with no fractional
+# part is stored in the database file as an integer to save space.
+# After extracting the value, we have to call OP_RealAffinity to
+# convert it back to a REAL.
+#
+# The sqlite3ExprCodeGetColumn() routine was added to take care of
+# all of the complications above.  The tests in this file attempt
+# to verify that sqlite3ExprCodeGetColumn() is used instead of a
+# raw OP_Column in all places where a table column is extracted from
+# the database.

+# Test Outline:
+#
+#   tkt-2409-1.*: Cause a cache-spill during an INSERT that is within
+#       a db transaction but does not start a statement transaction.
+#       Verify that the transaction is automatically rolled back
+#       and SQLITE_IOERR_BLOCKED is returned
+#
+#       UPDATE: As of the pcache modifications, failing to upgrade to
+#       an exclusive lock when attempting a cache-spill is no longer an
+#       error. The pcache module allocates more space and keeps working
+#       in memory if this occurs.
+#
+#   tkt-2409-2.*: Cause a cache-spill while updating the change-counter
+#       during a database COMMIT. Verify that the transaction is not
+#       rolled back and SQLITE_BUSY is returned.
+#
+#   tkt-2409-3.*: Similar to 2409-1.*, but using many INSERT statements
+#       within a transaction instead of just one.
+#
+#       UPDATE: Again, pcache now just keeps working in main memory.
+#
+#   tkt-2409-4.*: Similar to 2409-1.*, but rig it so that the
+#       INSERT statement starts a statement transaction. Verify that
+#       SQLITE_BUSY is returned and the transaction is not rolled back.
+#
+#       UPDATE: This time, SQLITE_BUSY is not returned. pcache just uses

+# The ORDER BY matching algorithm is three steps:
+# 
+#   (1)  If the ORDER BY term is an integer constant i, then
+#        sort by the i-th column of the result set.
+# 
+#   (2)  If the ORDER BY term is an identifier (not x.y or x.y.z
+#        but simply x) then look for a column alias with the same
+#        name.  If found, then sort by that column.
+# 
+#   (3)  Evaluate the term as an expression and sort by the
+#        value of the expression.
+# 
+# For a compound SELECT the rules are modified slightly.
+# In the third rule, the expression must exactly match one
+# of the result columns.  The sequences of three rules is
+# attempted first on the left-most SELECT.  If that doesn't
+# work, we move to the right, one by one.
+#
+# Rule (3) is not in standard SQL - it is an SQLite extension,
+# though one copied from PostgreSQL.  The rule for compound
+# queries where a search is made of SELECTs to the right
+# if the left-most SELECT does not match is not a part of
+# standard SQL either.  This extension is unique to SQLite
+# as far as we know.
+#
+# Rule (2) was added by the changes ticket #2822.  Prior to
+# that changes, SQLite did not support rule (2), making it
+# technically in violation of standard SQL semantics.  
+# No body noticed because rule (3) has the same effect as
+# rule (2) except in some obscure cases.
+#

+# Regression testing of FOR EACH ROW table triggers
+#
+# 1. Trigger execution order tests. 
+# These tests ensure that BEFORE and AFTER triggers are fired at the correct
+# times relative to each other and the triggering statement. 
+#
+# trigger2-1.1.*: ON UPDATE trigger execution model.
+# trigger2-1.2.*: DELETE trigger execution model.
+# trigger2-1.3.*: INSERT trigger execution model.
+#
+# 2. Trigger program execution tests.
+# These tests ensure that trigger programs execute correctly (ie. that a
+# trigger program can correctly execute INSERT, UPDATE, DELETE * SELECT
+# statements, and combinations thereof).
+#
+# 3. Selective trigger execution 
+# This tests that conditional triggers (ie. UPDATE OF triggers and triggers
+# with WHEN clauses) are fired only fired when they are supposed to be.
+#
+# trigger2-3.1: UPDATE OF triggers
+# trigger2-3.2: WHEN clause
+#
+# 4. Cascaded trigger execution 
+# Tests that trigger-programs may cause other triggers to fire. Also that a 
+# trigger-program is never executed recursively.
+# 
+# trigger2-4.1: Trivial cascading trigger
+# trigger2-4.2: Trivial recursive trigger handling 
+#
+# 5. Count changes behaviour.
+# Verify that rows altered by triggers are not included in the return value
+# of the "count changes" interface.
+#
+# 6. ON CONFLICT clause handling
+# trigger2-6.1[a-f]: INSERT statements
+# trigger2-6.2[a-f]: UPDATE statements
+#
+# 7. & 8. Triggers on views fire correctly.

+**     checkpoint_starvation_1
+**     checkpoint_starvation_2
+*/
+
+/*
+** Both test cases involve 1 writer/checkpointer thread and N reader threads.
+** 
+** Each reader thread performs a series of read transactions, one after 
+** another. Each read transaction lasts for 100 ms.
+**
+** The writer writes transactions as fast as possible. It uses a callback
+** registered with sqlite3_wal_hook() to try to keep the WAL-size limited to 
+** around 50 pages.
+**
+** In test case checkpoint_starvation_1, the auto-checkpoint uses 
+** SQLITE_CHECKPOINT_PASSIVE. In checkpoint_starvation_2, it uses RESTART.
+** The expectation is that in the first case the WAL file will grow very 
+** large, and in the second will be limited to the 50 pages or thereabouts.
+** However, the overall transaction throughput will be lower for 
+** checkpoint_starvation_2, as every checkpoint will block for up to 200 ms

+/*
+** This file implements an eponymous, read-only table-valued function
+** (a virtual table) designed to be used for testing.  We are not aware
+** of any practical real-world use case for the virtual table.
+**
+** This virtual table originated in the TH3 test suite.  It is still used
+** there, but has now been copied into the public SQLite source tree and
+** reused for a variety of testing purpose.  The name "vt02" comes from the
+** fact that there are many different testing virtual tables in TH3, of which
+** this one is the second.
+**
+** ## SUBJECT TO CHANGE
+**
+** Because this virtual table is intended for testing, its interface is not
+** guaranteed to be stable across releases.  Future releases may contain
+** changes in the vt02 design and interface.
+**
+** ## OVERVIEW
+**
+** The vt02 table-valued function has 10000 rows with 5 data columns.
+** Column X contains all integer values between 0 and 9999 inclusive.
+** Columns A, B, C, and D contain the individual base-10 digits associated
+** with each X value:
+**
+**      X     A  B  C  D
+**      ----  -  -  -  -
+**      0     0  0  0  0
+**      1     0  0  0  1
+**      2     0  0  0  2
+**              ...
+**      4998  4  9  9  8
+**      4999  4  9  9  9
+**      5000  5  0  0  0
+**              ...
+**      9995  9  9  9  5
+**      9996  9  9  9  6
+**      9997  9  9  9  7
+**
+** The xBestIndex method recognizes a variety of equality constraints
+** and attempts to optimize its output accordingly.
+**
+**      x=...
+**      a=...
+**      a=... AND b=...
+**      a=... AND b=... AND c=...
+**      a=... AND b=... AND c=... AND d=...
+**
+** Various ORDER BY constraints are also recognized and consumed.  The
+** OFFSET constraint is recognized and consumed.
+**
+** ## TABLE-VALUED FUNCTION
+**
+** The vt02 virtual table is eponymous and has two hidden columns, meaning
+** that it can functions a table-valued function.  The two hidden columns
+** are "flags" and "logtab", in that order.  The "flags" column can be set
+** to an integer where various bits enable or disable behaviors of the
+** virtual table.  The "logtab" can set to the name of an ordinary SQLite
+** table into which is written information about each call to xBestIndex.
+**
+** The bits of "flags" are as follows:
+**
+**       0x01           Ignore the aConstraint[].usable flag.  This might
+**                      result in the xBestIndex method incorrectly using
+**                      unusable entries in the aConstraint[] array, which
+**                      should result in the SQLite core detecting and
+**                      reporting that the virtual table is not behaving
+**                      to spec.
+**
+**       0x02           Do not set the orderByConsumed flag, even if it
+**                      could be set.
+**
+**       0x04           Do not consume the OFFSET constraint, if there is
+**                      one.  Instead, let the generated byte-code visit
+**                      and ignore the first few columns of output.
+**
+**       0x08           Use sqlite3_mprintf() to allocate an idxStr string.
+**                      The string is never used, but allocating it does
+**                      test the idxStr deallocation logic inside of the
+**                      SQLite core.
+**
+**       0x10           Cause the xBestIndex method to generate an idxNum
+**                      that xFilter does not understand, thus causing
+**                      the OP_VFilter opcode to raise an error.
+**
+**       0x20           Set the omit flag for all equality constraints on
+**                      columns X, A, B, C, and D that are used to limit
+**                      the search.
+**
+**       0x40           Add all constraints against X,A,B,C,D to the
+**                      vector of results sent to xFilter.  Only the first
+**                      few are used, as required by idxNum.
+**
+** Because these flags take effect during xBestIndex, the RHS of the
+** flag= constraint must be accessible.  In other words, the RHS of flag=
+** needs to be an integer literal, not another column of a join or a
+** bound parameter.
+**
+** ## LOGGING OUTPUT
+**
+** If the "logtab" columns is set, then each call to the xBestIndex method
+** inserts multiple rows into the table identified by "logtab".  These
+** rows collectively show the content of the sqlite3_index_info object and
+** other context associated with the xBestIndex call.
+**
+** If the table named by "logtab" does not previously exist, it is created
+** automatically.  The schema for the logtab table is like this:
+**
+**   CREATE TEMP TABLE vt02_log(
+**     bi INT,         -- BestIndex call counter
+**     vn TEXT,        -- Variable Name
+**     ix INT,         -- Index or value
+**     cn TEXT,        -- Column Name
+**     op INT,         -- Opcode or "DESC" value
+**     ux INT,         -- "Usable" flag
+**     ra BOOLEAN,     -- Right-hand side Available.
+**     rhs ANY,        -- Right-Hand Side value
+**     cs TEXT         -- Collating Sequence for this constraint
+**  );
+**
+** Because logging happens during xBestIindex, the RHS value of "logtab" must
+** be known to xBestIndex, which means it must be a string literal, not a
+** column in a join, or a bound parameter.
+** 
+** ## VIRTUAL TABLE SCHEMA
+**
+**    CREATE TABLE vt02(
+**      x INT,              -- integer between 0 and 9999 inclusive
+**      a INT,              -- The 1000s digit
+**      b INT,              -- The 100s digit
+**      c INT,              -- The 10s digit
+**      d INT,              -- The 1s digit
+**      flags INT HIDDEN,   -- Option flags
+**      logtab TEXT HIDDEN, -- Name of table into which to log xBestIndex
+**    );
+**
+** ## COMPILING AND RUNNING
+**
+** This file can also be compiled separately as a loadable extension
+** for SQLite (as long as the -DTH3_VERSION is not defined).  To compile as a
+** loadable extension do his:
+**
+**    gcc -Wall -g -shared -fPIC -I. -DSQLITE_DEBUG vt02.c -o vt02.so
+**
+** Or on Windows:
+**
+**    cl vt02.c -link -dll -out:vt02.dll
+**
+** Then load into the CLI using:
+**
+**    .load ./vt02 sqlite3_vt02_init
+**
+** ## IDXNUM SUMMARY
+**
+** The xBestIndex method communicates the query plan to xFilter using
+** the idxNum value, as follows:
+**

+
+#
+# These are 'warm-body' tests of database recovery used while developing

+#
+# walcrash-1.*: Recover a database.
+# walcrash-2.*: Recover a database where the failed transaction spanned more
+#               than one page.
+# walcrash-3.*: Recover multiple databases where the failed transaction 
+#               was a multi-file transaction.

+# This test case demonstrates a flaw in the wal-index manipulation that
+# existed at one point: If a process crashes mid-transaction, it may have
+# already added some entries to one of the hash-tables in the wal-index.
+# If the transaction were to be explicitly rolled back at this point, the
+# hash-table entries would be removed as part of the rollback. However,
+# if the process crashes, the transaction is implicitly rolled back and
+# the rogue entries remain in the hash table.
+#
+# Normally, this causes no problem - readers can tell the difference 
+# between committed and uncommitted entries in the hash table. However,
+# if it happens often enough that all slots in the hash-table become 
+# non-zero, the next process that attempts to read or write the hash
+# table falls into an infinite loop.
+#
+# Even if run with an SQLite version affected by the bug, this test case
+# only goes into an infinite loop if SQLite is compiled without SQLITE_DEBUG
+# defined. If SQLITE_DEBUG is defined, the program is halted by a failing
+# assert() before entering the infinite loop.
+#
+# walcrash2-1.1: Create a database. Commit a transaction that adds 8 frames
+#                to the WAL (and 8 entry to the first hash-table in the 
+#                wal-index).
+#
+# walcrash2-1.2: Have an external process open a transaction, add 8 entries
+#                to the wal-index hash-table, then crash. Repeat this 1023
+#                times (so that the wal-index contains 8192 entries - all
+#                slots are non-zero).
+#
+# walcrash2-1.3: Using a new database connection, attempt to query the

+# Test cases for query planning decisions.
+
+
+#
+# The tests in this file demonstrate the behaviour of the query planner
+# in determining the order in which joined tables are scanned.
+#
+# Assume there are two tables being joined - t1 and t2. Each has a cost
+# if it is the outer loop, and a cost if it is the inner loop. As follows:
+#
+#   t1(outer) - cost of scanning t1 as the outer loop.
+#   t1(inner) - cost of scanning t1 as the inner loop.
+#   t2(outer) - cost of scanning t2 as the outer loop.
+#   t2(inner) - cost of scanning t2 as the inner loop.
+#
+# Depending on the order in which the planner nests the scans, the total
+# cost of the join query is one of:

+# Test structure:
+#
+# without_rowid3-1.*: Simple tests to check that immediate and deferred foreign key 
+#            constraints work when not inside a transaction.
+#            
+# without_rowid3-2.*: Tests to verify that deferred foreign keys work inside
+#            explicit transactions (i.e that processing really is deferred).
+#
+# without_rowid3-3.*: Tests that a statement transaction is rolled back if an
+#            immediate foreign key constraint is violated.
+#
+# without_rowid3-4.*: Test that FK actions may recurse even when recursive triggers
+#            are disabled.
+#
+# without_rowid3-5.*: Check that if foreign-keys are enabled, it is not possible
+#            to write to an FK column using the incremental blob API.
+#
+# without_rowid3-6.*: Test that FK processing is automatically disabled when 
+#            running VACUUM.
+#
+# without_rowid3-7.*: Test using an IPK as the key in the child (referencing) table.
+#
+# without_rowid3-8.*: Test that enabling/disabling foreign key support while a 
+#            transaction is active is not possible.
+#
+# without_rowid3-9.*: Test SET DEFAULT actions.
+#
+# without_rowid3-10.*: Test errors.
+#
+# without_rowid3-11.*: Test CASCADE actions.
+#
+# without_rowid3-12.*: Test RESTRICT actions.
+#
+# without_rowid3-13.*: Test that FK processing is performed when a row is REPLACED by
+#             an UPDATE or INSERT statement.
+#
+# without_rowid3-14.*: Test the ALTER TABLE and DROP TABLE commands.
+#
+# without_rowid3-15.*: Test that if there are no (known) outstanding foreign key 
+#             constraint violations in the database, inserting into a parent
+#             table or deleting from a child table does not cause SQLite
+#             to check if this has repaired an outstanding violation.
+#
+# without_rowid3-16.*: Test that rows that refer to themselves may be inserted, 
+#             updated and deleted.
+#
+# without_rowid3-17.*: Test that the "count_changes" pragma does not interfere with
+#             FK constraint processing.
+# 
+# without_rowid3-18.*: Test that the authorization callback is invoked when processing
+#             FK constraints.
+#
+# without_rowid3-20.*: Test that ON CONFLICT clauses specified as part of statements
+#             do not affect the operation of FK constraints.
+#
+# without_rowid3-genfkey.*: Tests that were used with the shell tool .genfkey
+#            command. Recycled to test the built-in implementation.
+#
+# without_rowid3-dd08e5.*:  Tests to verify that ticket dd08e5a988d00decc4a543daa8d
+#                  has been fixed.

+# Regression testing of FOR EACH ROW table triggers on WITHOUT ROWID
+# tables.
+#
+# 1. Trigger execution order tests. 
+# These tests ensure that BEFORE and AFTER triggers are fired at the correct
+# times relative to each other and the triggering statement. 
+#
+# without_rowid4-1.1.*: ON UPDATE trigger execution model.
+# without_rowid4-1.2.*: DELETE trigger execution model.
+# without_rowid4-1.3.*: INSERT trigger execution model.
+#
+# 2. Trigger program execution tests.
+# These tests ensure that trigger programs execute correctly (ie. that a
+# trigger program can correctly execute INSERT, UPDATE, DELETE * SELECT
+# statements, and combinations thereof).
+#
+# 3. Selective trigger execution 
+# This tests that conditional triggers (ie. UPDATE OF triggers and triggers
+# with WHEN clauses) are fired only fired when they are supposed to be.
+#
+# without_rowid4-3.1: UPDATE OF triggers
+# without_rowid4-3.2: WHEN clause
+#
+# 4. Cascaded trigger execution 
+# Tests that trigger-programs may cause other triggers to fire. Also that a 
+# trigger-program is never executed recursively.
+# 
+# without_rowid4-4.1: Trivial cascading trigger
+# without_rowid4-4.2: Trivial recursive trigger handling 
+#
+# 5. Count changes behaviour.
+# Verify that rows altered by triggers are not included in the return value
+# of the "count changes" interface.
+#
+# 6. ON CONFLICT clause handling
+# without_rowid4-6.1[a-f]: INSERT statements
+# without_rowid4-6.2[a-f]: UPDATE statements

+/*
+** This C program extracts all "words" from an input document and adds them
+** to an SQLite database.  A "word" is any contiguous sequence of alphabetic
+** characters.  All digits, punctuation, and whitespace characters are 
+** word separators.  The database stores a single entry for each distinct
+** word together with a count of the number of occurrences of that word.
+** A fresh database is created automatically on each run.
+**
+**     wordcount DATABASE INPUTFILE
+**
+** The INPUTFILE name can be omitted, in which case input it taken from
+** standard input.
+**
+** Option:
+**
+**
+** Modes:
+**
+** Insert mode means:
+**    (1) INSERT OR IGNORE INTO wordcount VALUES($new,1)
+**    (2) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new -- if (1) is a noop
+**
+** Update mode means:
+**    (1) INSERT OR IGNORE INTO wordcount VALUES($new,0)
+**    (2) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new
+**
+** Replace mode means:
+**    (1) REPLACE INTO wordcount
+**        VALUES($new,ifnull((SELECT cnt FROM wordcount WHERE word=$new),0)+1);
+**
+** Upsert mode means:
+**    (1) INSERT INTO wordcount VALUES($new,1)
+**            ON CONFLICT(word) DO UPDATE SET cnt=cnt+1
+**
+** Select mode means:
+**    (1) SELECT 1 FROM wordcount WHERE word=$new
+**    (2) INSERT INTO wordcount VALUES($new,1) -- if (1) returns nothing
+**    (3) UPDATE wordcount SET cnt=cnt+1 WHERE word=$new  --if (1) return TRUE
+**
+** Delete mode means:
+**    (1) DELETE FROM wordcount WHERE word=$new
+**
+** Query mode means:
+**    (1) SELECT cnt FROM wordcount WHERE word=$new
+**
+** Note that delete mode and query mode are only useful for preexisting
+** databases.  The wordcount table is created using IF NOT EXISTS so this
+** utility can be run multiple times on the same database file.  The
+** --without-rowid, --nocase, and --pagesize parameters are only effective
+** when creating a new database and are harmless no-ops on preexisting
+** databases.
