+# README for Debian packaging contributors
+
+This documentation describes how to contribute to the official Debian packages
+of MariaDB. The packaging in Debian repositories is not identical to the packaging
+in mariadb.org repositories, but whatever is in Debian repositories will eventually
+be upstreamed.
+
+
+## Development environment and tools
+
+Use a recent version of Debian or Ubuntu as the environment for Debian packaging
+testing and development. Preferred environment is Debian Sid (unstable).
+
+Install the tool used to manage and build the source:
+
+    sudo apt-get install git-buildpackage
+
+
+## Getting the source
+
+The official Debian package source is hosted on the Debian Gitlab server under
+the MariaDB/MySQL packaging team at https://salsa.debian.org/mariadb-team/. You
+are welcome to fork it and make merge requests.
+
+To get the latest official Debian packaging source of `mariadb`, clone the
+source repository with all relevant branches (main branch `debian/latest`) to
+your local environment using _git-buildpackage_:
+
+    gbp clone https://salsa.debian.org/mariadb-team/mariadb-server.git
+
+If you have your own fork and SSH keys set up on Salsa, you can run:
+
+    gbp clone git@salsa.debian.org:<username>/mariadb-server.git
+
+
+The clone needs to be run only once. On later runs you can refresh your clone with
+relevant branches using:
+
+    gbp pull --force
+
+
+## Building the packages
+
+Build binaries, run testsuite and build Debian packages with:
+
+    gbp buildpackage
+
+On the first run git-buildpackage will complain if some of the build dependencies
+defined in debian/control are missing. Simply install those packages and run the
+build again.
+
+A quick command to install all dependencies:
+
+    sudo mk-build-deps -r -i debian/control -t "apt-get -y -o Debug::pkgProblemResolver=yes --no-install-recommends"
+
+If the build fails, the easiest way to clean up before a new run is
+
+    git clean -fdx && git reset --hard
+
+
+### Build options
+
+If you want to skip the mysql-test-run step (which takes a lot of time) set
+the following environment variable:
+
+    export DEB_BUILD_OPTIONS="nocheck"
+
+If you want to run the build in parallel on 2 CPUs and have verbose output:
+
+    export DEB_BUILD_OPTIONS="parallel=2 verbose"
+
+The options above can also be combined freely to get desired behavior.
+
+
+### Using special build environments
+
+If you want to ensure all build dependencies are clean, you can build inside a
+Docker or sbuild (Debian tool) environment.
+
+#### Build in Docker
+
+First make a working directory for the build artifacts. Inside that directory
+clone the repository. Then start a Docker session using whatever Debian/Ubuntu
+image you want with the command:
+
+    docker run -it -v ${PWD}:/build -w /build debian:sid bash
+
+This will start a session, where you are as the root user in the path /build
+inside the Docker container. Here you can `cd` into the source directory,
+install dependencies and start the build. Note that when you exit the session,
+everything will be lost apart from the files you had inside the mounted volume
+in `/build`.
+
+#### Build using sbuild
+
+If you prefer sbuild, you can build with something like:
+
+    gbp buildpackage --git-builder=sbuild -A -v -d unstable
+
+## Creating a feature or bugfix branch
+
+The repository layout follows the DEP-14 standard:
+https://dep-team.pages.debian.net/deps/dep14/
+
+All new features and also bug fixes are done only in the `debian/latest` branch.
+The release branches for Debian and Ubuntu are only used for security updates.
+
+To prepare the Salsa pull request, create a bugfix branch from master with:
+
+    git checkout -b bugfix/NNNNNN-example-name
+
+After this you can develop with all the usual git commit and push commands
+until you have in your fork at Salsa the desired change and you are ready
+to open the merge request.
+
+
+### Notes about how to make changes in the proper way
+
+First consider submitting your patch upstream. Upstream MariaDB makes frequent
+maintenance releases and any fix done upstream will therefore be included in
+Debian relatively quickly. You can send email to the developers mailing list
+or open a pull request at https://github.com/MariaDB/server.
+
+Follow these instructions if your fix is about packaging in Debian specifically.
+Start by using `gitk --all` or similar tool to browse the previous changes. Try
+to follow similar pattern in your new changes.
+
+Keep in mind that all changes must done only for files residing in the `debian/`
+sub-directory. If you need to create changes outside the `debian/` directory,
+then you need to create a patch file using the same pattern as the patches
+found in `debian/patches` and activated by a line in `debian/patches/series`.
+
+Do not bundle in your commit any changes to `debian/changelog`. The correct
+changelog entries will be created later by the maintainer using `git-dch` in an
+automated fashion.
+
+For an example of a patch adding commit see
+https://salsa.debian.org/mariadb-team/mariadb-server/-/commit/7972a38e
+
+
+# Quality assurance tips
+
+Ensure most packaging files are formatted correctly:
+
+    wrap-and-sort -av
+
+Check man pages for syntax errors:
+
+    LC_ALL=en_US.UTF-8 MANROFFSEQ='' MANWIDTH=80 man --warnings -E UTF-8 -l -Tutf8 -Z mariadb.1 >/dev/null
+
+Find spelling errors:
+
+    find * -type f | xargs spellintian
+
+
+# Debugging tips
+
+## Debug mariadb-test-run failures
+
+If the test suite is failing on Launchpad or some other CI system where you
+don't have access to the build artifacts, you can extend the debian/rules file
+to print out valuable information with the commands:
+
+    cd $(BUILDDIR)/mysql-test && find var/log/ -ls || true
+    cd $(BUILDDIR)/mysql-test && cat var/log/*.err || true
+    cd $(BUILDDIR)/mysql-test && tail -n 1000 var/log/*.log || true
+
+The `cd` is required on every line since it is a Makefile and the actual command
+needs to run in the correct directory. Also, the `|| true` at the end ensures
+the build will complete and not abort if any of those debug steps fail.
+
+## Debugging with gdb
+
+If the `mariadb-test-run` fails on a `mariadbd` crash it should produce a core
+dump file, from which a full stack trace can be produced with:
+
+    cd $(BUILDDIR)/mysql-test && gdb --batch --ex 'thr a a bt' var/log/*/mysqld.1/core || true
+
+To attach `gdb` on a running process and get a stack trace run:
+
+    gdb -p $(pgrep -x mariadbd) /usr/sbin/mariadbd
+    set height 0
+    set logging file /tmp/mysqld.log
+    set logging on
+    thread apply all backtrace full
+
+The readability of the stack traces depends on if symbols are available on the
+system. In Debian and Ubuntu all (C/C++) software is automatically built with
+debug symbols, but to save disk space they are distributed in separate packages
+(usually with `-dbg` or `-dbgsym` suffix) which users need to install in the
+rare case stack traces are needed. See the Debian and Ubuntu documentation on
+how to enable the repository that has the debug symbol packages.
+
+* https://wiki.ubuntu.com/Debug%20Symbol%20Packages
+* https://wiki.debian.org/HowToGetABacktrace
+
+## Debug build
+
+A debug build can be created using the following build flags:
+
+    -DCMAKE_BUILD_TYPE=Debug \
+    -DMYSQL_MAINTAINER_MODE=OFF \
+
+The latter flag ensures a build does not stop on warnings but continues to the
+end.
+
+A 'mariadbd' binary from a debug build can be started with argument '--debug' to
+be verbose about what is going on in the server. Debug binaries should not be
+used in production as they are slower than normal binaries.
+
+Core dumps and stack traces can be produced on any build running with
+`--core-file --stack-trace` and *debug builds are not needed to run `gdb`*.
+
+## Debugging a running server
+
+Linux distros come standard with tools like `strace` and `lsof` which can also
+be used to inspect what processes are doing (no need for debug build). For
+example to see what `mariadbd` is writing to the database files can be viewed
+with:
+
+    strace -ffp $(pgrep -x mariadbd) -e pwrite,write,fsync,fdatasync,sync,send,sendto,sendmsg
+    lsof -a -p $(pgrep -x mariadbd) | grep "/var/lib/mysql"
+
+## Compare changes between builds
+
+Diffoscope can be used to investigate small changes between recent builds:
+
+    docker run --rm -t -w $(pwd) -v $(pwd):$(pwd) registry.salsa.debian.org/reproducible-builds/diffoscope --html-dir report mariadb-server-1.deb mariadb-server-2.deb
+    firefox report/index.html
+
+## Test autopkgtest locally
+
+If Debian CI fails (or Ubuntu CI) one might need to debug the autopkgtests
+manually. The easiest way to do it is to start a Docker container that has
+access to the packaging source directory via a local mount:
+
+    laptop$ docker run -it -v ${PWD}:/build -w /build debian:sid bash
+    container$ apt update && apt install -y autopkgtest
+    container$ autopkgtest --no-built-binaries --shell-fail -- null
+
+Edit the files in `debian/tests` in your favorite code editor and re-run the
+`autopkgtest -- null` until the tests are passing. When the autopkgtests work
+the container can be shut down and the valid `debian/tests` committed in git.
+
+If you want to iterate on a single test, use `--test-name`, e.g.
+`autopkgtest --no-built-binaries --test-name=configuration-tracing -- null`.
+
+If you don't want to use the MariaDB binaries from Debian Sid but instead build
+them from the source tree to be used in autopkgtest directly, simply omit
+`--no-built-binaries` from the `autopkgtest` command.
+
+For more information please read:
+* https://manpages.debian.org/unstable/autopkgtest/autopkgtest.1.en.html
+* https://salsa.debian.org/ci-team/autopkgtest/-/tree/master/doc
+
+## Debug installation/upgrade
+
+To see what exactly the Debian maintainer scripts run, they can be made verbose with:
+
+    export DEBIAN_SCRIPT_DEBUG=1
+    apt install ...
+
+The source files of the Debian maintainer scripts are not the final ones, as the
+package building stage may make changes and additions to them. To view a
+maintainer script in the final form on an installed system run:
+
+    cat /var/lib/dpkg/info/mariadb-server.postinst
+
+To review the my.cnf status run:
+
+    find /etc/mysql/ -ls
+    update-alternatives --display my.cnf
+
+## Debug apt Depends/Conflicts/Breaks
+
+It can be quite frustrating to debug situations where `apt` (or `apt-get`) fails
+on an install or upgrade with an error message like:
+
+    The following packages have unmet dependencies:
+     mariadb-client : Depends: mariadb-client-10.5 but 1:10.5.12 is to be installed
+     mariadb-server : Depends: mariadb-server-10.5 but 1:10.5.12 is to be installed
+     mariadb-test : Depends: mariadb-client-10.5 but 1:10.5.12 is to be installed
+                    Depends: mariadb-server-10.5 but 1:10.5.12 is to be installed
+    E: Unable to correct problems, you have held broken packages.
+
+To make apt show debug information on what it tried to resolve and how it failed
+enable debug features by addin a file in `/etc/apt/apt.conf.d/` with:
+
+   Debug::pkgProblemResolver 1;
+   Debug::pkgDepCache::AutoInstall 1;
+   Debug::pkgDepCache::Marker 1;
+
+>lternatively append options directly to `apt` commands:
+
+    apt dist-upgrade -o Debug::pkgProblemResolver=1
+
+It can be also quite annoying to rebuild the entire package to debug small
+changes in the `debian/control` file. To have a much faster change->test->change
+cycle one can simply instruct `apt` to use a custom `Packages` file to read the
+`control` data.
+
+First ensure `apt` forgets all repositories:
+
+    rm /etc/apt/sources.list
+    apt clean
+    apt update
+
+Download a Packages file for so it can be edited:
+
+    curl -O http://ftp.debian.org/debian/dists/sid/main/binary-amd64/Packages.xz
+    unxz Packages.xz
+    cp Packages Packages.orig
+
+Open the file in an editor, scroll down to the MariadB packages and make any
+changes you want and then test them:
+
+    nano Packages
+    apt install --with-source ./Packages -s mariadb-server -o Debug::pkgDepCache::Marker=1 -o Debug::pkgDepCache::AutoInstall=1 -o Debug::pkgProblemResolver=1
+
+The example uses maximum verbosity but it is naturally not mandatory. When the
+solution has been found, compare to the original and transfer the changes into
+the actual debian/control in the MariaDB packaging:
+
+    diff -u Packages.orig Packages
+
+## Test install/upgrade with local package repository
+
+Normally the fastest way to test that the built *.deb files install and upgrade
+properly is simply to run `apt` directly on them inside a container that has
+access to the .deb files via a local mount:
+
+    laptop$ docker run -it -v ${PWD}:/build -w /build debian:sid bash
+    container$ apt update && apt install ./*.deb
+
+Some bugs however occur only when apt does various dependency resolving and can
+only be tested with an installation from an actual apt repository. The fastest
+way to get a directory with deb files served via a local repository is to run:
+
+    apt install apt-utils
+    apt-ftparchive packages . > Packages
+    apt-ftparchive release . > Release
+    echo 'deb [trusted=yes] file:/build/mariadb-bionic ./' >> /etc/apt/sources.list
+    apt update
+    apt install mariadb-server
+
+The example above assumes that the .deb files are in path `/build`.
+
+## Check Breaks/Replaces
+
+MariaDB is not only a massive package by itself, it also has several parallel
+major releases at any given time and also other variants (MySQL, Percona Server)
+the packaging might interact with.
+
+The standard Salsa-CI pipeline checks Breaks/Replaces for what is currently in
+the Debian repositories, but to check Breaks/Replaces across all known
+repositories one needs to run:
+
+    docker run -it -v ${PWD}:/build -w /build debian:sid bash
+    apt update
+    apt install --yes python3-junit.xml python3-debian apt-file
+    curl -O https://salsa.debian.org/salsa-ci-team/pipeline/-/raw/master/images/scripts/check_for_missing_breaks_replaces.py
+    chmod +x check_for_missing_breaks_replaces.py
+    apt install --no-install-recommends --yes gpg gpg-agent dirmngr ca-certificates curl debian-archive-keyring

+## Check reverse dependencies
+
+When making changes to the MariaDB packaging in Debian and Ubuntu, keep in mind
+that there are hundreds of packages that depend on MariaDB. Most of them can be
+found by running:
+
+    apt rdepends 'default-mysql*' 'default-libmysql*' 'mariadb*' 'libmariadb*'
+
+The separate command/package 'apt-rdepends' can also check for reverse
+build-dependencies.
+
+Please be diligent in all changes to not wreak havoc in Debian.

+# README for Debian package maintainers
+
+This file mostly applies to how the packaging work-flow works for the official
+Debian packages, but it may contain useful information also for anybody doing
+their own private .deb builds.
+
+## Version control
+
+This package is maintained by the MariaDB/MySQL team in Debian using the
+git-buildpackage tool and storing the git repositories on the Debian Gitlab
+instance Salsa. For details see https://salsa.debian.org/mariadb-team/.
+
+The official Ubuntu packages are also maintained by the same team using the same
+source repository.
+
+### Ensuring git contents match what has been uploaded to Debian/Ubuntu
+
+It is possible (but extremely rare) that somebody uploads a MariaDB package to
+Debian/Ubuntu and either does not use git at all, or simply forgets to push the
+same changes on git, or makes an error in tagging the release or something.
+Therefore, maintainers should check that the git contents match what has been
+uploaded to Debian/Ubuntu before making new changes on git.
+
+This can be done by using dgit. The example command below will fetch the latest
+mariadb-10.1 package available in Ubuntu 18.04 (Bionic) base archive, security
+archive or updates archive (whichever has a newer version):
+
+    dgit -d ubuntu clone mariadb-10.6 jammy,-security,-updates
+    cp -ra mariadb-10.6/* .
+    rm -rf mariadb-10.6
+
+You can then compare these two directories with a recursive diff or `git diff`.
+
+
+Another option is to manually check on packages.debian.org or packages.ubuntu.com
+what is the latest version, and download and extract it on top of the existing
+debian/ directory with:
+
+    curl -SL https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/mariadb-10.6/\
+    1:10.6.7-2ubuntu1.1/mariadb-10.6_10.6.7-2ubuntu1.1.debian.tar.xz -o - | tar xv --xz
+
+You can simply run `git diff` to see the report on differences.
+
+
+## Building from sources with git-buildpackage
+
+See README.Contributor for details.
+
+
+## Upgrading sources from upstream
+
+Upstream will publish maintenance releases at least 5 years after the major
+version release, and security updates are likely to come even after that as
+long as major distributions ship the version.
+
+See table at
+https://mariadb.com/kb/en/mariadb/development/mariadb-maintenance-policy/
+
+Release notes are available at
+https://mariadb.com/kb/en/mariadb/development/release-notes/
+
+
+### Steps to import new upstream version
+
+Download new source package:
+
+    git checkout 10.11
+    git pull --tags upstream 10.11
+    git tag -v mariadb-10.11.3
+    git checkout debian/latest
+    git merge -v mariadb-10.11.3
+
+Refresh patches:
+
+    while quilt push; do quilt refresh; done; quilt pop -a
+
+Simple offsets will be updated automatically. If there are any rejects, inspect
+the files and update the patches or discard the patch completely if you are
+_sure_ that it has been applied upstream.
+
+Generate new debian/changelog entry automatically with git-dch:
+
+    gbp dch -vR
+
+Edit the details to match correct release:
+
+    gedit debian/changelog &
+
+Commit to git:
+
+    git citool
+
+Build and test locally to verify it works:
+
+    gbp buildpackage
+
+Alternatively you can use Docker with something like this:
+
+    mkdir ccache buildout
+    docker run -it -v "${PWD}/buildout":/tmp/build -v "${PWD}/ccache":/.ccache \
+       -v "${PWD}/$PKG":/tmp/build/source -w /tmp/build/source \
+       -e DEB_BUILD_OPTIONS="$DEB_BUILD_OPTIONS" -e CCACHE_DIR=/var/cache/ccache \
+       --user=1001 registry.gitlab.com/mariadb/mariadb.org-build-containers:$PKG-debian-sid-build-env \
+       gbp buildpackage | tee latest.build
+
+If needed, add commits or amend the ones you made until the package is in
+perfect shape.
+
+Let Lintian automatically check as much as possible:
+
+    lintian -EvIL +pedantic --color=always *.changes
+
+Then proceed to make a source only build:
+
+    gbp buildpackage -S
+
+Test more with upload to Launchpad:
+
+    COMMIT_ID=`git log -n 1 --oneline | cut -d ' ' -f 1`
+    PKG=mariadb-10.6
+    backportpackage --yes -u ppa:mysql-ubuntu/$PKG -d groovy -S ~`date '+%s'`.$COMMIT_ID $PKG*.dsc
+
+When done, push to Salsa:
+
+    gbp push # gbp branches and tags
+    git push # master branch
+
+Wait until the Salsa CI pipeline finishes. If it did not either spot any
+regressions, proceed to tagging the commit:
+
+    gbp tag
+    gbp push
+
+Once you are sure there are no regressions, finally upload to Debian:
+
+    dput ftp-master *.changes
+
+After the upload, check that everything is OK at
+* https://tracker.debian.org/mariadb (Debian)
+* https://launchpad.net/ubuntu/+source/mariadb-10.6 (Ubuntu)
+
+## Maintaining translations
+
+Running `debconf-updatepo --verbose` will refresh the translation files.
+
+A call for translations can be initiated with e.g. `podebconf-report-po --call -v --smtp=smtp.kolumbus.fi`.
+
+### Launchpad testing matrix
+
+Since Launchpad only has Ubuntu releases, packages for specific Debian releases
+needs to be tested on the Ubuntu release which most closely matches the Debian
+release in question. The following matrix maps what package should be tested
+where:
+
+- 10.6 for sid on Launchpad lunar
+- 10.6 for kinetic on Launchpad kinetic
+- 10.6 for jammy on Launchpad jammy
+- 10.5 for bullseye on Launchpad hirsute (not available anymore)
+- 10.3 for focal on Launchpad focal
+- 10.3 for buster on Launchpad disco (not available anymore)
+- 10.1 for bionic on Launchpad bionic

+regressions before they spread out to too many users.
+
+Upload priority for 10.6
+- debian sid
+- ubuntu-22.10 kinetic
+- ubuntu-22.04 jammy
+
+Upload priority for 10.5
+- debian-11 bullseye

+- ubuntu-18.04 bionic
+- debian-9 stretch
+
+## Comparison to other distributions
+
+For tracking security release information, finding solutions for build errors
+on many architectures and for general quality control it can be useful to keep
+an eye on what packagers in other distributions do:
+
+Fedora:
+  * https://apps.fedoraproject.org/packages/mariadb/
+  * http://pkgs.fedoraproject.org/cgit/mariadb.git/
+OpenSUSE:
+  * https://build.opensuse.org/package/show/server:database/mariadb
+Arch Linux:

+=head1 NAME
+
+innotop - MySQL and InnoDB transaction/status monitor.
+
+=head1 SYNOPSIS
+
+To monitor servers normally:
+
+ innotop
+
+To monitor InnoDB status information from a file:
+
+ innotop /var/log/mysql/mysqld.err
+
+To run innotop non-interactively in a pipe-and-filter configuration:
+
+ innotop --count 5 -d 1 -n
+
+To monitor a database on another system using a particular username and password:
+
+ innotop -u <username> -p <password> -h <hostname>
+
+=head1 DESCRIPTION
+
+innotop monitors MySQL servers.  Each of its modes shows you a different aspect
+of what's happening in the server.  For example, there's a mode for monitoring
+replication, one for queries, and one for transactions.  innotop refreshes its
+data periodically, so you see an updating view.
+
+innotop has lots of features for power users, but you can start and run it with
+virtually no configuration.  If you're just getting started, see
+L<"QUICK-START">.  Press '?' at any time while running innotop for
+context-sensitive help.
+
+=head1 QUICK-START
+
+To start innotop, open a terminal or command prompt.  If you have installed
+innotop on your system, you should be able to just type "innotop" and press
+Enter; otherwise, you will need to change to innotop's directory and type "perl
+innotop".
+
+With no options specified, innotop will attempt to connect to a MySQL server on
+localhost using mariadb_read_default_group=client for other connection
+parameters.  If you need to specify a different username and password, use the
+-u and -p options, respectively.  To monitor a MySQL database on another
+host, use the -h option.
+
+After you've connected, innotop should show you something like the following:
+
+ [RO] Query List (? for help) localhost, 01:11:19, 449.44 QPS, 14/7/163 con/run
+
+ CXN        When   Load  QPS    Slow  QCacheHit  KCacheHit  BpsIn    BpsOut
+ localhost  Total  0.00  1.07k   697      0.00%     98.17%  476.83k  242.83k

+ localhost  Query  766446598  test  10.0.0.1  foo  00:02  INSERT INTO table (
+
+
+(This sample is truncated at the right so it will fit on a terminal when running
+'man innotop')
+
+If your server is busy, you'll see more output.  Notice the first line on the
+screen, which tells you that readonly is set to true ([RO]), what mode you're
+in and what server you're connected to.  You can change to other modes with
+keystrokes; press 'T' to switch to a list of InnoDB transactions, for example.
+
+Press the '?' key to see what keys are active in the current mode.  You can
+press any of these keys and innotop will either take the requested action or
+prompt you for more input.  If your system has Term::ReadLine support, you can
+use TAB and other keys to auto-complete and edit input.
+
+To quit innotop, press the 'q' key.
+
+=head1 OPTIONS
+
+innotop is mostly configured via its configuration file, but some of the
+configuration options can come from the command line.  You can also specify a
+file to monitor for InnoDB status output; see L<"MONITORING A FILE"> for more
+details.
+
+You can negate some options by prefixing the option name with --no.  For
+example, --noinc (or --no-inc) negates L<"--inc">.
+
+=over
+
+=item --color
+
+Enable or disable terminal coloring.  Corresponds to the L<"color"> config file
+setting.
+
+=item --config
+
+Specifies a configuration file to read.  This option is non-sticky, that is to
+say it does not persist to the configuration file itself.
+
+=item --count
+
+Refresh only the specified number of times (ticks) before exiting.  Each refresh
+is a pause for L<"interval"> seconds, followed by requesting data from MySQL
+connections and printing it to the terminal.
+
+=item --delay
+
+Specifies the amount of time to pause between ticks (refreshes).  Corresponds to
+the configuration option L<"interval">.
+
+=item --help
+
+Print a summary of command-line usage and exit.
+
+=item --host
+
+Host to connect to.
+
+=item --inc
+
+Specifies whether innotop should display absolute numbers or relative numbers
+(offsets from their previous values).  Corresponds to the configuration option
+L<"status_inc">.
+
+=item --mode
+
+Specifies the mode in which innotop should start.  Corresponds to the
+configuration option L<"mode">.
+
+=item --nonint
+
+Enable non-interactive operation.  See L<"NON-INTERACTIVE OPERATION"> for more.
+
+=item --password
+
+Password to use for connection.
+
+=item --port
+
+Port to use for connection.
+
+=item --skipcentral
+
+Don't read the central configuration file.
+
+=item --timestamp
+
+In -n mode, write a timestamp either before every screenful of output, or if
+the option is given twice, at the start of every line.  The format is controlled
+by the timeformat config variable.
+
+=item --user
+
+User to use for connection.
+
+=item --version
+
+Output version information and exit.
+
+=item --write
+
+Sets the configuration option L<"readonly"> to 0, making innotop write the
+running configuration to ~/.innotop/innotop.conf on exit, if no configuration
+file was loaded at start-up.
+
+=back
+
+=head1 HOTKEYS
+
+innotop is interactive, and you control it with key-presses.
+
+=over
+
+=item *
+
+Uppercase keys switch between modes.
+
+=item *
+
+Lowercase keys initiate some action within the current mode.
+
+=item *
+
+Other keys do something special like change configuration or show the
+innotop license.
+
+=back
+
+Press '?' at any time to see the currently active keys and what they do.
+
+=head1 MODES
+
+Each of innotop's modes retrieves and displays a particular type of data from
+the servers you're monitoring.  You switch between modes with uppercase keys.
+The following is a brief description of each mode, in alphabetical order.  To
+switch to the mode, press the key listed in front of its heading in the
+following list:
+
+=over
+
+=item A: Health Dashboard
+
+This mode displays a single table with one row per monitored server. The
+columns show essential overview information about the server's health, and
+coloration rules show whether replication is running or if there are any very
+long-running queries or excessive replication delay.
+
+=item B: InnoDB Buffers
+
+This mode displays information about the InnoDB buffer pool, page statistics,
+insert buffer, and adaptive hash index.  The data comes from SHOW INNODB STATUS.
+
+This mode contains the L<"buffer_pool">, L<"page_statistics">,
+L<"insert_buffers">, and L<"adaptive_hash_index"> tables by default.
+
+=item C: Command Summary
+
+This mode is similar to mytop's Command Summary mode.  It shows the
+L<"cmd_summary"> table, which looks something like the following:
+
+ Command Summary (? for help) localhost, 25+07:16:43, 2.45 QPS, 3 thd, 5.0.40
+ _____________________ Command Summary _____________________
+ Name                    Value    Pct     Last Incr  Pct
+ Select_scan             3244858  69.89%          2  100.00%
+ Select_range            1354177  29.17%          0    0.00%
+ Select_full_join          39479   0.85%          0    0.00%
+ Select_full_range_join     4097   0.09%          0    0.00%
+ Select_range_check            0   0.00%          0    0.00%
+
+The command summary table is built by extracting variables from
+L<"STATUS_VARIABLES">.  The variables must be numeric and must match the prefix
+given by the L<"cmd_filter"> configuration variable.  The variables are then
+sorted by value descending and compared to the last variable, as shown above.
+The percentage columns are percentage of the total of all variables in the
+table, so you can see the relative weight of the variables.
+
+The example shows what you see if the prefix is "Select_".  The default
+prefix is "Com_".  You can choose a prefix with the 's' key.
+
+It's rather like running SHOW VARIABLES LIKE "prefix%" with memory and
+nice formatting.
+
+Values are aggregated across all servers.  The Pct columns are not correctly
+aggregated across multiple servers.  This is a known limitation of the grouping
+algorithm that may be fixed in the future.
+
+=item D: InnoDB Deadlocks
+
+This mode shows the transactions involved in the last InnoDB deadlock.  A second
+table shows the locks each transaction held and waited for.  A deadlock is
+caused by a cycle in the waits-for graph, so there should be two locks held and
+one waited for unless the deadlock information is truncated.
+
+InnoDB puts deadlock information before some other information in the SHOW
+INNODB STATUS output.  If there are a lot of locks, the deadlock information can
+grow very large, and there is a limit on the size of the SHOW INNODB
+STATUS output.  A large deadlock can fill the entire output, or even be
+truncated, and prevent you from seeing other information at all.  If you are
+running innotop in another mode, for example T mode, and suddenly you don't see
+anything, you might want to check and see if a deadlock has wiped out the data
+you need.
+
+If it has, you can create a small deadlock to replace the large one.  Use the
+'w' key to 'wipe' the large deadlock with a small one.  This will not work
+unless you have defined a deadlock table for the connection (see L<"SERVER
+CONNECTIONS">).
+
+You can also configure innotop to automatically detect when a large deadlock
+needs to be replaced with a small one (see L<"auto_wipe_dl">).
+
+This mode displays the L<"deadlock_transactions"> and L<"deadlock_locks"> tables
+by default.
+
+=item F: InnoDB Foreign Key Errors
+
+This mode shows the last InnoDB foreign key error information, such as the
+table where it happened, when and who and what query caused it, and so on.
+
+InnoDB has a huge variety of foreign key error messages, and many of them are
+just hard to parse.  innotop doesn't always do the best job here, but there's
+so much code devoted to parsing this messy, unparseable output that innotop is
+likely never to be perfect in this regard.  If innotop doesn't show you what
+you need to see, just look at the status text directly.
+
+This mode displays the L<"fk_error"> table by default.
+
+=item I: InnoDB I/O Info
+
+This mode shows InnoDB's I/O statistics, including the I/O threads, pending I/O,
+file I/O miscellaneous, and log statistics.  It displays the L<"io_threads">,
+L<"pending_io">, L<"file_io_misc">, and L<"log_statistics"> tables by default.
+
+=item K: InnoDB Lock Waits
+
+This mode shows information from InnoDB plugin's transaction and locking tables.
+You can use it to find when a transaction is waiting for another, and kill the
+blocking transaction. It displays the L<"innodb_blocked_blocker>" table.
+
+=item L: Locks
+
+This mode shows information about current locks.  At the moment only InnoDB
+locks are supported, and by default you'll only see locks for which transactions
+are waiting.  This information comes from the TRANSACTIONS section of the InnoDB
+status text.  If you have a very busy server, you may have frequent lock waits;
+it helps to be able to see which tables and indexes are the "hot spot" for
+locks.  If your server is running pretty well, this mode should show nothing.
+
+You can configure MySQL and innotop to monitor not only locks for which a
+transaction is waiting, but those currently held, too.  You can do this with the
+InnoDB Lock Monitor (L<http://dev.mysql.com/doc/en/innodb-monitor.html>).  It's
+not documented in the MySQL manual, but creating the lock monitor with the
+following statement also affects the output of SHOW INNODB STATUS, which innotop
+uses:
+
+  CREATE TABLE innodb_lock_monitor(a int) ENGINE=INNODB;
+
+This causes InnoDB to print its output to the MySQL file every 16 seconds or so,
+as stated in the manual, but it also makes the normal SHOW INNODB STATUS output
+include lock information, which innotop can parse and display (that's the
+undocumented feature).
+
+This means you can do what may have seemed impossible: to a limited extent
+(InnoDB truncates some information in the output), you can see which transaction
+holds the locks something else is waiting for.  You can also enable and disable
+the InnoDB Lock Monitor with the key mappings in this mode.
+
+This mode displays the L<"innodb_locks"> table by default.  Here's a sample of
+the screen when one connection is waiting for locks another connection holds:
+
+ _________________________________ InnoDB Locks __________________________
+ CXN        ID  Type    Waiting  Wait   Active  Mode  DB    Table  Index
+ localhost  12  RECORD        1  00:10   00:10  X     test  t1     PRIMARY
+ localhost  12  TABLE         0  00:10   00:10  IX    test  t1
+ localhost  12  RECORD        1  00:10   00:10  X     test  t1     PRIMARY
+ localhost  11  TABLE         0  00:00   00:25  IX    test  t1
+ localhost  11  RECORD        0  00:00   00:25  X     test  t1     PRIMARY
+
+You can see the first connection, ID 12, is waiting for a lock on the PRIMARY
+key on test.t1, and has been waiting for 10 seconds.  The second connection
+isn't waiting, because the Waiting column is 0, but it holds locks on the same
+index.  That tells you connection 11 is blocking connection 12.
+
+=item M: Master/Slave Replication Status
+
+This mode shows the output of SHOW SLAVE STATUS and SHOW MASTER STATUS in three
+tables.  The first two divide the slave's status into SQL and I/O thread status,
+and the last shows master status.  Filters are applied to eliminate non-slave
+servers from the slave tables, and non-master servers from the master table.
+
+This mode displays the L<"slave_sql_status">, L<"slave_io_status">, and
+L<"master_status"> tables by default.
+
+=item O: Open Tables
+
+This section comes from MySQL's SHOW OPEN TABLES command.  By default it is
+filtered to show tables which are in use by one or more queries, so you can
+get a quick look at which tables are 'hot'.  You can use this to guess which
+tables might be locked implicitly.
+
+This mode displays the L<"open_tables"> mode by default.
+
+=item U: User Statistics
+
+This mode displays data that's available in Percona's enhanced version of MySQL
+(also known as Percona Server with XtraDB).  Specifically, it makes it easy to
+enable and disable the so-called "user statistics."  This feature gathers stats
+on clients, threads, users, tables, and indexes and makes them available as
+INFORMATION_SCHEMA tables.  These are invaluable for understanding what your
+server is doing.  They are also available in MariaDB.
+
+The statistics supported so far are only from the TABLE_STATISTICS and
+INDEX_STATISTICS tables added by Percona.  There are three views: one of table stats,
+one of index stats (which can be aggregated with the = key), and one of both.
+
+The server doesn't gather these stats by default.  You have to set the variable
+userstat_running to turn it on.  You can do this easily with innotop from U mode,
+with the 's' key.
+
+=item Q: Query List
+
+This mode displays the output from SHOW FULL PROCESSLIST, much like B<mytop>'s
+query list mode.  This mode does B<not> show InnoDB-related information.  This
+is probably one of the most useful modes for general usage.
+
+There is an informative header that shows general status information about
+your server.  You can toggle it on and off with the 'h' key.  By default,
+innotop hides inactive processes and its own process.  You can toggle these on
+and off with the 'i' and 'a' keys.
+
+You can EXPLAIN a query from this mode with the 'e' key.  This displays the
+query's full text, the results of EXPLAIN, and in newer MySQL versions, even
+the optimized query resulting from EXPLAIN EXTENDED.  innotop also tries to
+rewrite certain queries to make them EXPLAIN-able.  For example, INSERT/SELECT
+statements are rewritable.
+
+This mode displays the L<"q_header"> and L<"processlist"> tables by default.
+
+=item R: InnoDB Row Operations and Semaphores
+
+This mode shows InnoDB row operations, row operation miscellaneous, semaphores,
+and information from the wait array.  It displays the L<"row_operations">,
+L<"row_operation_misc">, L<"semaphores">, and L<"wait_array"> tables by default.
+
+=item S: Variables & Status
+
+This mode calculates statistics, such as queries per second, and prints them out
+in several different styles.  You can show absolute values, or incremental values
+between ticks.
+
+You can switch between the views by pressing a key.  The 's' key prints a
+single line each time the screen updates, in the style of B<vmstat>.  The 'g'
+key changes the view to a graph of the same numbers, sort of like B<tload>.
+The 'v' key changes the view to a pivoted table of variable names on the left,
+with successive updates scrolling across the screen from left to right.  You can
+choose how many updates to put on the screen with the L<"num_status_sets">
+configuration variable.
+
+Headers may be abbreviated to fit on the screen in interactive operation.  You
+choose which variables to display with the 'c' key, which selects from
+predefined sets, or lets you create your own sets.  You can edit the current set
+with the 'e' key.
+
+This mode doesn't really display any tables like other modes.  Instead, it uses
+a table definition to extract and format the data, but it then transforms the
+result in special ways before outputting it.  It uses the L<"var_status"> table
+definition for this.
+
+=item T: InnoDB Transactions
+
+This mode shows transactions from the InnoDB monitor's output, in B<top>-like
+format.  This mode is the reason I wrote innotop.
+
+You can kill queries or processes with the 'k' and 'x' keys, and EXPLAIN a query
+with the 'e' or 'f' keys.  InnoDB doesn't print the full query in transactions,
+so explaining may not work right if the query is truncated.
+
+The informational header can be toggled on and off with the 'h' key.  By
+default, innotop hides inactive transactions and its own transaction.  You can
+toggle this on and off with the 'i' and 'a' keys.
+
+This mode displays the L<"t_header"> and L<"innodb_transactions"> tables by
+default.
+
+=back
+
+=head1 INNOTOP STATUS
+
+The first line innotop displays is a "status bar" of sorts.  What it contains
+depends on the mode you're in, and what servers you're monitoring.  The first
+few words are always [RO] (if readonly is set to 1), the innotop mode, such as
+"InnoDB Txns" for T mode, followed by a reminder to press '?' for help at any
+time.
+
+=head2 ONE SERVER
+
+The simplest case is when you're monitoring a single server.  In this case, the
+name of the connection is next on the status line.  This is the name you gave
+when you created the connection -- most likely the MySQL server's hostname.
+This is followed by the server's uptime.
+
+If you're in an InnoDB mode, such as T or B, the next word is "InnoDB" followed
+by some information about the SHOW INNODB STATUS output used to render the
+screen.  The first word is the number of seconds since the last SHOW INNODB
+STATUS, which InnoDB uses to calculate some per-second statistics.  The next is
+a smiley face indicating whether the InnoDB output is truncated.  If the smiley
+face is a :-), all is well; there is no truncation.  A :^| means the transaction
+list is so long, InnoDB has only printed out some of the transactions.  Finally,
+a frown :-( means the output is incomplete, which is probably due to a deadlock
+printing too much lock information (see L<"D: InnoDB Deadlocks">).
+
+The next two words indicate the server's queries per second (QPS) and how many
+threads (connections) exist.  Finally, the server's version number is the last
+thing on the line.
+
+=head2 MULTIPLE SERVERS
+
+If you are monitoring multiple servers (see L<"SERVER CONNECTIONS">), the status
+line does not show any details about individual servers.  Instead, it shows the
+names of the connections that are active.  Again, these are connection names you
+specified, which are likely to be the server's hostname.  A connection that has
+an error is prefixed with an exclamation point.
+
+If you are monitoring a group of servers (see L<"SERVER GROUPS">), the status
+line shows the name of the group.  If any connection in the group has an
+error, the group's name is followed by the fraction of the connections that
+don't have errors.
+
+See L<"ERROR HANDLING"> for more details about innotop's error handling.
+
+=head2 MONITORING A FILE
+
+If you give a filename on the command line, innotop will not connect to ANY
+servers at all.  It will watch the specified file for InnoDB status output and
+use that as its data source.  It will always show a single connection called
+'file'.  And since it can't connect to a server, it can't determine how long the
+server it's monitoring has been up; so it calculates the server's uptime as time
+since innotop started running.
+
+=head1 SERVER ADMINISTRATION
+
+While innotop is primarily a monitor that lets you watch and analyze your
+servers, it can also send commands to servers.  The most frequently useful
+commands are killing queries and stopping or starting slaves.
+
+You can kill a connection, or in newer versions of MySQL kill a query but not a
+connection, from L<"Q: Query List"> and L<"T: InnoDB Transactions"> modes.
+Press 'k' to issue a KILL command, or 'x' to issue a KILL QUERY command.
+innotop will prompt you for the server and/or connection ID to kill (innotop
+does not prompt you if there is only one possible choice for any input).
+innotop pre-selects the longest-running query, or the oldest connection.
+Confirm the command with 'y'.
+
+In L<"M: Master/Slave Replication Status"> mode, you can start and stop slaves
+with the 'a' and 'o' keys, respectively.  You can send these commands to many
+slaves at once.  innotop fills in a default command of START SLAVE or STOP SLAVE
+for you, but you can actually edit the command and send anything you wish, such
+as SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1 to make the slave skip one binlog event
+when it starts.
+
+You can also ask innotop to calculate the earliest binlog in use by any slave
+and issue a PURGE MASTER LOGS on the master.  Use the 'b' key for this.  innotop
+will prompt you for a master to run the command on, then prompt you for the
+connection names of that master's slaves (there is no way for innotop to
+determine this reliably itself).  innotop will find the minimum binlog in use by
+these slave connections and suggest it as the argument to PURGE MASTER LOGS.
+
+in L<"U: User Statistics"> mode, you can use the 's' key to start and stop
+the collection of the statistics data for TABLE_STATISTICS and similar.
+
+=head1 SERVER CONNECTIONS
+
+When you create a server connection using '@', innotop asks you for a series of
+inputs, as follows:
+
+=over
+
+=item DSN
+
+A DSN is a Data Source Name, which is the initial argument passed to the DBI
+module for connecting to a server.  It is usually of the form
+
+ DBI:MariaDB:;mariadb_read_default_group=mysql;host=HOSTNAME
+
+Since this DSN is passed to the DBD::MariaDB driver, you should read the driver's
+documentation at L<https://metacpan.org/pod/DBD::MariaDB> for
+the exact details on all the options you can pass the driver in the DSN.  You
+can read more about DBI at L<http://dbi.perl.org/docs/>, and especially at
+L<http://search.cpan.org/~timb/DBI/DBI.pm>.
+
+The mariadb_read_default_group=mysql option lets the DBD driver read your MySQL
+options files, such as ~/.my.cnf on UNIX-ish systems.  You can use this to avoid
+specifying a username or password for the connection.
+
+=item InnoDB Deadlock Table
+
+This optional item tells innotop a table name it can use to deliberately create
+a small deadlock (see L<"D: InnoDB Deadlocks">).  If you specify this option,
+you just need to be sure the table doesn't exist, and that innotop can create
+and drop the table with the InnoDB storage engine.  You can safely omit or just
+accept the default if you don't intend to use this.
+
+=item Username
+
+innotop will ask you if you want to specify a username.  If you say 'y', it will
+then prompt you for a user name.  If you have a MySQL option file that specifies
+your username, you don't have to specify a username.
+
+The username defaults to your login name on the system you're running innotop on.
+
+=item Password
+
+innotop will ask you if you want to specify a password.  Like the username, the
+password is optional, but there's an additional prompt that asks if you want to
+save the password in the innotop configuration file.  If you don't save it in
+the configuration file, innotop will prompt you for a password each time it
+starts.  Passwords in the innotop configuration file are saved in plain text,
+not encrypted in any way.
+
+=back
+
+Once you finish answering these questions, you should be connected to a server.
+But innotop isn't limited to monitoring a single server; you can define many
+server connections and switch between them by pressing the '@' key.  See
+L<"SWITCHING BETWEEN CONNECTIONS">.
+
+=head1 SERVER GROUPS
+
+If you have multiple MySQL instances, you can put them into named groups, such
+as 'all', 'masters', and 'slaves', which innotop can monitor all together.
+
+You can choose which group to monitor with the '#' key, and you can press the
+TAB key to switch to the next group.  If you're not currently monitoring a
+group, pressing TAB selects the first group.
+
+To create a group, press the '#' key and type the name of your new group, then
+type the names of the connections you want the group to contain.
+
+=head1 SWITCHING BETWEEN CONNECTIONS
+
+innotop lets you quickly switch which servers you're monitoring.  The most basic
+way is by pressing the '@' key and typing the name(s) of the connection(s) you
+want to use.  This setting is per-mode, so you can monitor different connections
+in each mode, and innotop remembers which connections you choose.
+
+You can quickly switch to the 'next' connection in alphabetical order with the
+'n' key.  If you're monitoring a server group (see L<"SERVER GROUPS">) this will
+switch to the first connection.
+
+You can also type many connection names, and innotop will fetch and display data
+from them all.  Just separate the connection names with spaces, for example
+"server1 server2."  Again, if you type the name of a connection that doesn't
+exist, innotop will prompt you for connection information and create the
+connection.
+
+Another way to monitor multiple connections at once is with server groups.  You
+can use the TAB key to switch to the 'next' group in alphabetical order, or if
+you're not monitoring any groups, TAB will switch to the first group.
+
+innotop does not fetch data in parallel from connections, so if you are
+monitoring a large group or many connections, you may notice increased delay
+between ticks.
+
+When you monitor more than one connection, innotop's status bar changes.  See
+L<"INNOTOP STATUS">.
+
+=head1 ERROR HANDLING
+
+Error handling is not that important when monitoring a single connection, but is
+crucial when you have many active connections.  A crashed server or lost
+connection should not crash innotop.  As a result, innotop will continue to run
+even when there is an error; it just won't display any information from the
+connection that had an error.  Because of this, innotop's behavior might confuse
+you.  It's a feature, not a bug!
+
+innotop does not continue to query connections that have errors, because they
+may slow innotop and make it hard to use, especially if the error is a problem
+connecting and causes a long time-out.  Instead, innotop retries the connection
+occasionally to see if the error still exists.  If so, it will wait until some
+point in the future.  The wait time increases in ticks as the Fibonacci series,
+so it tries less frequently as time passes.
+
+Since errors might only happen in certain modes because of the SQL commands
+issued in those modes, innotop keeps track of which mode caused the error.  If
+you switch to a different mode, innotop will retry the connection instead of
+waiting.
+
+By default innotop will display the problem in red text at the bottom of the
+first table on the screen.  You can disable this behavior with the
+L<"show_cxn_errors_in_tbl"> configuration option, which is enabled by default.
+If the L<"debug"> option is enabled, innotop will display the error at the
+bottom of every table, not just the first.  And if L<"show_cxn_errors"> is
+enabled, innotop will print the error text to STDOUT as well.  Error messages
+might only display in the mode that caused the error, depending on the mode and
+whether innotop is avoiding querying that connection.
+
+=head1 NON-INTERACTIVE OPERATION
+
+You can run innotop in non-interactive mode, in which case it is entirely
+controlled from the configuration file and command-line options.  To start
+innotop in non-interactive mode, give the L"<--nonint"> command-line option.
+This changes innotop's behavior in the following ways:
+
+=over
+
+=item *
+
+Certain Perl modules are not loaded.  Term::Readline is not loaded, since
+innotop doesn't prompt interactively.  Term::ANSIColor and Win32::Console::ANSI
+modules are not loaded.  Term::ReadKey is still used, since innotop may have to
+prompt for connection passwords when starting up.
+
+=item *
+
+innotop does not clear the screen after each tick.
+
+=item *
+
+innotop does not persist any changes to the configuration file.
+
+=item *
+
+If L<"--count"> is given and innotop is in incremental mode (see L<"status_inc">
+and L<"--inc">), innotop actually refreshes one more time than specified so it
+can print incremental statistics.  This suppresses output during the first
+tick, so innotop may appear to hang.
+
+=item *
+
+innotop only displays the first table in each mode.  This is so the output can
+be easily processed with other command-line utilities such as awk and sed.  To
+change which tables display in each mode, see L<"TABLES">.  Since L<"Q: Query
+List"> mode is so important, innotop automatically disables the L<"q_header">
+table.  This ensures you'll see the L<"processlist"> table, even if you have
+innotop configured to show the q_header table during interactive operation.
+Similarly, in L<"T: InnoDB Transactions"> mode, the L<"t_header"> table is
+suppressed so you see only the L<"innodb_transactions"> table.
+
+=item *
+
+All output is tab-separated instead of being column-aligned with whitespace, and
+innotop prints the full contents of each table instead of only printing one
+screenful at a time.
+
+=item *
+
+innotop only prints column headers once instead of every tick (see
+L<"hide_hdr">).  innotop does not print table captions (see
+L<"display_table_captions">).  innotop ensures there are no empty lines in the
+output.
+
+=item *
+
+innotop does not honor the L<"shorten"> transformation, which normally shortens
+some numbers to human-readable formats.
+
+=item *
+
+innotop does not print a status line (see L<"INNOTOP STATUS">).
+
+=back
+
+=head1 CONFIGURING
+
+Nearly everything about innotop is configurable.  Most things are possible to
+change with built-in commands, but you can also edit the configuration file.
+
+While running innotop, press the '$' key to bring up the configuration editing
+dialog.  Press another key to select the type of data you want to edit:
+
+=over
+
+=item S: Statement Sleep Times
+
+Edits SQL statement sleep delays, which make innotop pause for the specified
+amount of time after executing a statement.  See L<"SQL STATEMENTS"> for a
+definition of each statement and what it does.  By default innotop does not
+delay after any statements.
+
+This feature is included so you can customize the side-effects caused by
+monitoring your server.  You may not see any effects, but some innotop users
+have noticed that certain MySQL versions under very high load with InnoDB
+enabled take longer than usual to execute SHOW GLOBAL STATUS.  If innotop calls
+SHOW FULL PROCESSLIST immediately afterward, the processlist contains more
+queries than the machine actually averages at any given moment.  Configuring
+innotop to pause briefly after calling SHOW GLOBAL STATUS alleviates this
+effect.
+
+Sleep times are stored in the L<"stmt_sleep_times"> section of the configuration
+file.  Fractional-second sleeps are supported, subject to your hardware's
+limitations.
+
+=item c: Edit Columns
+
+Starts the table editor on one of the displayed tables.  See L<"TABLE EDITOR">.
+An alternative way to start the table editor without entering the configuration
+dialog is with the '^' key.
+
+=item g: General Configuration
+
+Starts the configuration editor to edit global and mode-specific configuration
+variables (see L<"MODES">).  innotop prompts you to choose a variable from among
+the global and mode-specific ones depending on the current mode.
+
+=item k: Row-Coloring Rules
+
+Starts the row-coloring rules editor on one of the displayed table(s).  See
+L<"COLORS"> for details.
+
+=item p: Manage Plugins
+
+Starts the plugin configuration editor.  See L<"PLUGINS"> for details.
+
+=item s: Server Groups
+
+Lets you create and edit server groups.  See L<"SERVER GROUPS">.
+
+=item t: Choose Displayed Tables
+
+Lets you choose which tables to display in this mode.  See L<"MODES"> and
+L<"TABLES">.
+
+=back
+
+=head1 CONFIGURATION FILE
+
+innotop's default configuration file locations are $HOME/.innotop and
+/etc/innotop/innotop.conf, and they are looked for in that order.  If the first
+configuration file exists, the second will not be processed.  Those can be
+overridden with the L<"--config"> command-line option.  You can edit it by hand
+safely, however innotop reads the configuration file when it starts, and, if
+readonly is set to 0, writes it out again when it exits.  Thus, if readonly is
+set to 0, any changes you make by hand while innotop is running will be lost.
+
+innotop doesn't store its entire configuration in the configuration file.  It
+has a huge set of default configuration values that it holds only in memory,
+and the configuration file only overrides these defaults.  When you customize a
+default setting, innotop notices, and then stores the customizations into the
+file.  This keeps the file size down, makes it easier to edit, and makes
+upgrades easier.
+
+A configuration file is read-only be default.  You can override that with
+L<"--write">.  See L<"readonly">.
+
+The configuration file is arranged into sections like an INI file.  Each
+section begins with [section-name] and ends with [/section-name].  Each
+section's entries have a different syntax depending on the data they need to
+store.  You can put comments in the file; any line that begins with a #
+character is a comment.  innotop will not read the comments, so it won't write
+them back out to the file when it exits.  Comments in read-only configuration
+files are still useful, though.
+
+The first line in the file is innotop's version number.  This lets innotop
+notice when the file format is not backwards-compatible, and upgrade smoothly
+without destroying your customized configuration.
+
+The following list describes each section of the configuration file and the data
+it contains:
+
+=over
+
+=item general
+
+The 'general' section contains global configuration variables and variables that
+may be mode-specific, but don't belong in any other section.  The syntax is a
+simple key=value list.  innotop writes a comment above each value to help you
+edit the file by hand.
+
+=over
+
+=item S_func
+
+Controls S mode presentation (see L<"S: Variables & Status">).  If g, values are
+graphed; if s, values are like vmstat; if p, values are in a pivoted table.
+
+=item S_set
+
+Specifies which set of variables to display in L<"S: Variables & Status"> mode.
+See L<"VARIABLE SETS">.
+
+=item auto_wipe_dl
+
+Instructs innotop to automatically wipe large deadlocks when it notices them.
+When this happens you may notice a slight delay.  At the next tick, you will
+usually see the information that was being truncated by the large deadlock.
+
+=item charset
+
+Specifies what kind of characters to allow through the L<"no_ctrl_char">
+transformation.  This keeps non-printable characters from confusing a
+terminal when you monitor queries that contain binary data, such as images.
+
+The default is 'ascii', which considers anything outside normal ASCII to be a
+control character.  The other allowable values are 'unicode' and 'none'.  'none'
+considers every character a control character, which can be useful for
+collapsing ALL text fields in queries.
+
+=item cmd_filter
+
+This is the prefix that filters variables in L<"C: Command Summary"> mode.
+
+=item color
+
+Whether terminal coloring is permitted.
+
+=item cxn_timeout
+
+On MySQL versions 4.0.3 and newer, this variable is used to set the connection's
+timeout, so MySQL doesn't close the connection if it is not used for a while.
+This might happen because a connection isn't monitored in a particular mode, for
+example.
+
+=item debug
+
+This option enables more verbose errors and makes innotop more strict in some
+places.  It can help in debugging filters and other user-defined code.  It also
+makes innotop write a lot of information to L<"debugfile"> when there is a
+crash.
+
+=item debugfile
+
+A file to which innotop will write information when there is a crash.  See
+L<"FILES">.
+
+=item display_table_captions
+
+innotop displays a table caption above most tables.  This variable suppresses or
+shows captions on all tables globally.  Some tables are configured with the
+hide_caption property, which overrides this.
+
+=item global
+
+Whether to show GLOBAL variables and status.  innotop only tries to do this on
+servers which support the GLOBAL option to SHOW VARIABLES and SHOW STATUS.  In
+some MySQL versions, you need certain privileges to do this; if you don't have
+them, innotop will not be able to fetch any variable and status data.  This
+configuration variable lets you run innotop and fetch what data you can even
+without the elevated privileges.
+
+I can no longer find or reproduce the situation where GLOBAL wasn't allowed, but
+I know there was one.
+
+=item graph_char
+
+Defines the character to use when drawing graphs in L<"S: Variables & Status">
+mode.
+
+=item header_highlight
+
+Defines how to highlight column headers.  This only works if Term::ANSIColor is
+available.  Valid values are 'bold' and 'underline'.
+
+=item hide_hdr
+
+Hides column headers globally.
+
+=item interval
+
+The interval at which innotop will refresh its data (ticks).  The interval is
+implemented as a sleep time between ticks, so the true interval will vary
+depending on how long it takes innotop to fetch and render data.
+
+This variable accepts fractions of a second.
+
+=item mode
+
+The mode in which innotop should start.  Allowable arguments are the same as the
+key presses that select a mode interactively.  See L<"MODES">.
+
+=item num_digits
+
+How many digits to show in fractional numbers and percents.  This variable's
+range is between 0 and 9 and can be set directly from L<"S: Variables & Status">
+mode with the '+' and '-' keys.  It is used in the L<"set_precision">,
+L<"shorten">, and L<"percent"> transformations.
+
+=item num_status_sets
+
+Controls how many sets of status variables to display in pivoted L<"S: Variables
+& Status"> mode.  It also controls the number of old sets of variables innotop
+keeps in its memory, so the larger this variable is, the more memory innotop
+uses.
+
+=item plugin_dir
+
+Specifies where plugins can be found.  By default, innotop stores plugins in the
+'plugins' subdirectory of your innotop configuration directory.
+
+=item readonly
+
+Whether the configuration file is readonly.  This cannot be set interactively.
+
+=item show_cxn_errors
+
+Makes innotop print connection errors to STDOUT.  See L<"ERROR HANDLING">.
+
+=item show_cxn_errors_in_tbl
+
+Makes innotop display connection errors as rows in the first table on screen.
+See L<"ERROR HANDLING">.
+
+=item show_percent
+
+Adds a '%' character after the value returned by the L<"percent">
+transformation.
+
+=item show_statusbar
+
+Controls whether to show the status bar in the display.  See L<"INNOTOP
+STATUS">.
+
+=item skip_innodb
+
+Disables fetching SHOW INNODB STATUS, in case your server(s) do not have InnoDB
+enabled and you don't want innotop to try to fetch it.  This can also be useful
+when you don't have the SUPER privilege, required to run SHOW INNODB STATUS.
+
+=item spark
+
+Specifies how wide a spark chart is. There are two ASCII spark charts in A
+mode, showing QPS and User_threads_running.
+
+=item status_inc
+
+Whether to show absolute or incremental values for status variables.
+Incremental values are calculated as an offset from the last value innotop saw
+for that variable.  This is a global setting, but will probably become
+mode-specific at some point.  Right now it is honored a bit inconsistently; some
+modes don't pay attention to it.
+
+=item timeformat
+
+The C-style strftime()-compatible format for the timestamp line to be printed
+in -n mode when -t is set.
+
+=back
+
+=item plugins
+
+This section holds a list of package names of active plugins.  If the plugin
+exists, innotop will activate it.  See L<"PLUGINS"> for more information.
+
+=item filters
+
+This section holds user-defined filters (see L<"FILTERS">).  Each line is in the
+format filter_name=text='filter text' tbls='table list'.
+
+The filter text is the text of the subroutine's code.  The table list is a list
+of tables to which the filter can apply.  By default, user-defined filters apply
+to the table for which they were created, but you can manually override that by
+editing the definition in the configuration file.
+
+=item active_filters
+
+This section stores which filters are active on each table.  Each line is in the
+format table_name=filter_list.
+
+=item tbl_meta
+
+This section stores user-defined or user-customized columns (see L<"COLUMNS">).
+Each line is in the format col_name=properties, where the properties are a
+name=quoted-value list.
+
+=item connections
+
+This section holds the server connections you have defined.  Each line is in
+the format name=properties, where the properties are a name=value list.  The
+properties are self-explanatory, and the only one that is treated specially is
+'pass' which is only present if 'savepass' is set.  This section of the
+configuration file will be skipped if any DSN, username, or password
+command-line options are used.  See L<"SERVER CONNECTIONS">.

+
+This section holds a list of which server group is active in each mode.  Each
+line is in the format mode_name=server_group.
+
+=item max_values_seen
+
+This section holds the maximum values seen for variables.  This is used to scale
+the graphs in L<"S: Variables & Status"> mode.  Each line is in the format
+name=value.

+=item active_columns
+
+This section holds table column lists.  Each line is in the format

+=head1 CUSTOMIZING
+
+You can customize innotop a great deal.  For example, you can:
+
+=over
+
+=item *
+
+Choose which tables to display, and in what order.
+
+=item *
+
+Choose which columns are in those tables, and create new columns.
+
+=item *
+
+Filter which rows display with built-in filters, user-defined filters, and
+quick-filters.
+
+=item *
+
+Sort the rows to put important data first or group together related rows.
+
+=item *
+
+Highlight rows with color.
+
+=item *
+
+Customize the alignment, width, and formatting of columns, and apply
+transformations to columns to extract parts of their values or format the values
+as you wish (for example, shortening large numbers to familiar units).
+
+=item *
+
+Design your own expressions to extract and combine data as you need.  This gives
+you unlimited flexibility.
+
+=back
+
+All these and more are explained in the following sections.
+
+=head2 TABLES
+
+A table is what you'd expect: a collection of columns.  It also has some other
+properties, such as a caption.  Filters, sorting rules, and colorization rules
+belong to tables and are covered in later sections.
+
+Internally, table meta-data is defined in a data structure called %tbl_meta.
+This hash holds all built-in table definitions, which contain a lot of default
+instructions to innotop.  The meta-data includes the caption, a list of columns
+the user has customized, a list of columns, a list of visible columns, a list of
+filters, color rules, a sort-column list, sort direction, and some information
+about the table's data sources.  Most of this is customizable via the table
+editor (see L<"TABLE EDITOR">).
+
+You can choose which tables to show by pressing the '$' key.  See L<"MODES"> and
+L<"TABLES">.
+
+The table life-cycle is as follows:

+=item *

+Each table begins with a data source, which is an array of hashes.  See below
+for details on data sources.
+
+=item *
+
+Each element of the data source becomes a row in the final table.
+
+=item *
+
+For each element in the data source, innotop extracts values from the source and
+creates a row.  This row is another hash, which later steps will refer to as
+$set.  The values innotop extracts are determined by the table's columns.  Each
+column has an extraction subroutine, compiled from an expression (see
+L<"EXPRESSIONS">).  The resulting row is a hash whose keys are named the same as
+the column name.
+
+=item *
+
+innotop filters the rows, removing those that don't need to be displayed.  See
+L<"FILTERS">.
+
+=item *
+
+innotop sorts the rows.  See L<"SORTING">.
+
+=item *
+
+innotop groups the rows together, if specified.  See L<"GROUPING">.
+
+=item *
+
+innotop colorizes the rows.  See L<"COLORS">.
+
+=item *
+
+innotop transforms the column values in each row.  See L<"TRANSFORMATIONS">.
+
+=item *
+
+innotop optionally pivots the rows (see L<"PIVOTING">), then filters and sorts
+them.
+
+=item *
+
+innotop formats and justifies the rows as a table.  During this step, innotop
+applies further formatting to the column values, including alignment, maximum
+and minimum widths.  innotop also does final error checking to ensure there are
+no crashes due to undefined values.  innotop then adds a caption if specified,
+and the table is ready to print.
+
+=back
+
+The lifecycle is slightly different if the table is pivoted, as noted above.  To
+clarify, if the table is pivoted, the process is extract, group, transform,
+pivot, filter, sort, create.  If it's not pivoted, the process is extract,
+filter, sort, group, color, transform, create.  This slightly convoluted process
+doesn't map all that well to SQL, but pivoting complicates things pretty
+thoroughly.  Roughly speaking, filtering and sorting happen as late as needed to
+effect the final result as you might expect, but as early as possible for
+efficiency.

+
+=head2 COLUMNS
+
+Columns belong to tables.  You can choose a table's columns by pressing the '^'
+key, which starts the L<"TABLE EDITOR"> and lets you choose and edit columns.
+Pressing 'e' from within the table editor lets you edit the column's properties:
+
+=over
+
+=item *
+
+hdr: a column header.  This appears in the first row of the table.
+
+=item *
+
+just: justification.  '-' means left-justified and '' means right-justified,
+just as with printf formatting codes (not a coincidence).
+
+=item *
+
+dec: whether to further align the column on the decimal point.
+
+=item *
+
+num: whether the column is numeric.  This affects how values are sorted
+(lexically or numerically).
+
+=item *
+
+label: a small note about the column, which appears in dialogs that help the
+user choose columns.
+
+=item *
+
+src: an expression that innotop uses to extract the column's data from its
+source (see L<"DATA SOURCES">).  See L<"EXPRESSIONS"> for more on expressions.
+
+=item *
+
+minw: specifies a minimum display width.  This helps stabilize the display,
+which makes it easier to read if the data is changing frequently.
+
+=item *
+
+maxw: similar to minw.
+
+=item *
+
+trans: a list of column transformations.  See L<"TRANSFORMATIONS">.
+
+=item *
+
+agg: an aggregate function.  See L<"GROUPING">.  The default is L<"first">.
+
+=item *
+
+aggonly: controls whether the column only shows when grouping is enabled on the
+table (see L<"GROUPING">).  By default, this is disabled.  This means columns
+will always be shown by default, whether grouping is enabled or not.  If a
+column's aggonly is set true, the column will appear when you toggle grouping on
+the table.  Several columns are set this way, such as the count column on
+L<"processlist"> and L<"innodb_transactions">, so you don't see a count when the
+grouping isn't enabled, but you do when it is.
+
+=item *
+
+agghide: the reverse of aggonly.  The column is hidden when grouping is enabled.
+
+=back
+
+=head2 FILTERS
+
+Filters remove rows from the display.  They behave much like a WHERE clause in
+SQL.  innotop has several built-in filters, which remove irrelevant information
+like inactive queries, but you can define your own as well.  innotop also lets
+you create quick-filters, which do not get saved to the configuration file, and
+are just an easy way to quickly view only some rows.
+
+You can enable or disable a filter on any table.  Press the '%' key (mnemonic: %
+looks kind of like a line being filtered between two circles) and choose which
+table you want to filter, if asked.  You'll then see a list of possible filters
+and a list of filters currently enabled for that table.  Type the names of
+filters you want to apply and press Enter.
+
+=head3 USER-DEFINED FILTERS
+
+If you type a name that doesn't exist, innotop will prompt you to create the
+filter.  Filters are easy to create if you know Perl, and not hard if you don't.
+What you're doing is creating a subroutine that returns true if the row should
+be displayed.  The row is a hash reference passed to your subroutine as $set.
+
+For example, imagine you want to filter the processlist table so you only see
+queries that have been running more than five minutes.  Type a new name for your
+filter, and when prompted for the subroutine body, press TAB to initiate your
+terminal's auto-completion.  You'll see the names of the columns in the
+L<"processlist"> table (innotop generally tries to help you with auto-completion
+lists).  You want to filter on the 'time' column.  Type the text "$set->{time} >
+300" to return true when the query is more than five minutes old.  That's all
+you need to do.
+
+In other words, the code you're typing is surrounded by an implicit context,
+which looks like this:
+
+ sub filter {
+    my ( $set ) = @_;
+    # YOUR CODE HERE
+ }
+
+If your filter doesn't work, or if something else suddenly behaves differently,
+you might have made an error in your filter, and innotop is silently catching
+the error.  Try enabling L<"debug"> to make innotop throw an error instead.
+
+=head3 QUICK-FILTERS
+
+innotop's quick-filters are a shortcut to create a temporary filter that doesn't
+persist when you restart innotop.  To create a quick-filter, press the '/' key.
+innotop will prompt you for the column name and filter text.  Again, you can use
+auto-completion on column names.  The filter text can be just the text you want
+to "search for."  For example, to filter the L<"processlist"> table on queries
+that refer to the products table, type '/' and then 'info product'.  Internally,
+the filter is compiled into a subroutine like this:
+
+ sub filter {
+    my ( $set ) = @_;
+    $set->{info} =~ m/product/;
+ }
+
+The filter text can actually be any Perl regular expression, but of course a
+literal string like 'product' works fine as a regular expression.
+
+What if you want the filter to discard matching rows, rather than showing
+matching rows?  If you're familiar with Perl regular expressions, you might
+guess how to do this.  You have to use a zero-width negative lookahead
+assertion.  If you don't know what that means, don't worry.  Let's filter out
+all rows where the command is Gandalf.  Type the following:
+
+ 1. /
+ 2. cmd ^(?!Gandalf)
+
+Behind the scenes innotop compiles the quick-filter into a specially tagged
+filter that is otherwise like any other filter.  It just isn't saved to the
+configuration file.
+
+To clear quick-filters, press the '\' key and innotop will clear them all at
+once.
+
+=head2 SORTING
+
+innotop has sensible built-in defaults to sort the most important rows to the
+top of the table.  Like anything else in innotop, you can customize how any
+table is sorted.
+
+To start the sort dialog, start the L<"TABLE EDITOR"> with the '^' key, choose a
+table if necessary, and press the 's' key.  You'll see a list of columns you can
+use in the sort expression and the current sort expression, if any.  Enter a
+list of columns by which you want to sort and press Enter.  If you want to
+reverse sort, prefix the column name with a minus sign.  For example, if you
+want to sort by column a ascending, then column b descending, type 'a -b'.  You
+can also explicitly add a + in front of columns you want to sort ascending, but
+it's not required.
+
+Some modes have keys mapped to open this dialog directly, and to quickly reverse
+sort direction.  Press '?' as usual to see which keys are mapped in any mode.
+
+=head2 GROUPING
+
+innotop can group, or aggregate, rows together (the terms are used
+interchangeably).  This is quite similar to an SQL GROUP BY clause.  You can
+specify to group on certain columns, or if you don't specify any, the entire set
+of rows is treated as one group.  This is quite like SQL so far, but unlike SQL,
+you can also select un-grouped columns.  innotop actually aggregates every
+column.  If you don't explicitly specify a grouping function, the default is
+'first'.  This is basically a convenience so you don't have to specify an
+aggregate function for every column you want in the result.
+
+You can quickly toggle grouping on a table with the '=' key, which toggles its
+aggregate property.  This property doesn't persist to the config file.
+
+The columns by which the table is grouped are specified in its group_by
+property.  When you turn grouping on, innotop places the group_by columns at the
+far left of the table, even if they're not supposed to be visible.  The rest of
+the visible columns appear in order after them.
+
+Two tables have default group_by lists and a count column built in:
+L<"processlist"> and L<"innodb_transactions">.  The grouping is by connection
+and status, so you can quickly see how many queries or transactions are in a
+given status on each server you're monitoring.  The time columns are aggregated
+as a sum; other columns are left at the default 'first' aggregation.
+
+By default, the table shown in L<"S: Variables & Status"> mode also uses
+grouping so you can monitor variables and status across many servers.  The
+default aggregation function in this mode is 'avg'.
+
+Valid grouping functions are defined in the %agg_funcs hash.  They include
+
+=over
+
+=item first
+
+Returns the first element in the group.
+
+=item count
+
+Returns the number of elements in the group, including undefined elements, much
+like SQL's COUNT(*).
+
+=item avg
+
+Returns the average of defined elements in the group.
+
+=item sum
+
+Returns the sum of elements in the group.
+
+=back
+
+Here's an example of grouping at work.  Suppose you have a very busy server with
+hundreds of open connections, and you want to see how many connections are in
+what status.  Using the built-in grouping rules, you can press 'Q' to enter
+L<"Q: Query List"> mode.  Press '=' to toggle grouping (if necessary, select the
+L<"processlist"> table when prompted).
+
+Your display might now look like the following:
+
+ Query List (? for help) localhost, 32:33, 0.11 QPS, 1 thd, 5.0.38-log
+
+ CXN        Cmd        Cnt  ID      User   Host           Time   Query
+ localhost  Query      49    12933  webusr localhost      19:38  SELECT * FROM
+ localhost  Sending Da 23     2383  webusr localhost      12:43  SELECT col1,
+ localhost  Sleep      120     140  webusr localhost    5:18:12
+ localhost  Statistics 12    19213  webusr localhost      01:19  SELECT * FROM
+
+That's actually quite a worrisome picture.  You've got a lot of idle connections
+(Sleep), and some connections executing queries (Query and Sending Data).
+That's okay, but you also have a lot in Statistics status, collectively spending
+over a minute.  That means the query optimizer is having a really hard time
+generating execution plans for your statements.  Something is wrong; it should
+normally take milliseconds to plan queries.  You might not have seen this pattern if you
+didn't look at your connections in aggregate.  (This is a made-up example, but
+it can happen in real life).
+
+=head2 PIVOTING
+
+innotop can pivot a table for more compact display, similar to a Pivot Table in
+a spreadsheet (also known as a crosstab).  Pivoting a table makes columns into
+rows.  Assume you start with this table:
+
+ foo bar
+ === ===
+ 1   3
+ 2   4
+
+After pivoting, the table will look like this:
+
+ name set0 set1
+ ==== ==== ====
+ foo  1    2
+ bar  3    4
+
+To get reasonable results, you might need to group as well as pivoting.
+innotop currently does this for L<"S: Variables & Status"> mode.
+
+=head2 COLORS
+
+By default, innotop highlights rows with color so you can see at a glance which
+rows are more important.  You can customize the colorization rules and add your
+own to any table.  Open the table editor with the '^' key, choose a table if
+needed, and press 'o' to open the color editor dialog.
+
+The color editor dialog displays the rules applied to the table, in the order
+they are evaluated.  Each row is evaluated against each rule to see if the rule
+matches the row; if it does, the row gets the specified color, and no further
+rules are evaluated.  The rules look like the following:
+
+ state  eq  Locked       black on_red
+ cmd    eq  Sleep        white
+ user   eq  system user  white
+ cmd    eq  Connect      white
+ cmd    eq  Binlog Dump  white
+ time   >   600          red
+ time   >   120          yellow
+ time   >   60           green
+ time   >   30           cyan
+
+This is the default rule set for the L<"processlist"> table.  In order of
+priority, these rules make locked queries black on a red background, "gray out"
+connections from replication and sleeping queries, and make queries turn from
+cyan to red as they run longer.
+
+(For some reason, the ANSI color code "white" is actually a light gray.  Your
+terminal's display may vary; experiment to find colors you like).
+
+You can use keystrokes to move the rules up and down, which re-orders their
+priority.  You can also delete rules and add new ones.  If you add a new rule,
+innotop prompts you for the column, an operator for the comparison, a value
+against which to compare the column, and a color to assign if the rule matches.
+There is auto-completion and prompting at each step.
+
+The value in the third step needs to be correctly quoted.  innotop does not try
+to quote the value because it doesn't know whether it should treat the value as
+a string or a number.  If you want to compare the column against a string, as
+for example in the first rule above, you should enter 'Locked' surrounded by
+quotes.  If you get an error message about a bareword, you probably should have
+quoted something.
+
+=head2 EXPRESSIONS
+
+Expressions are at the core of how innotop works, and are what enables you to
+extend innotop as you wish.  Recall the table lifecycle explained in
+L<"TABLES">.  Expressions are used in the earliest step, where it extracts
+values from a data source to form rows.
+
+It does this by calling a subroutine for each column, passing it the source data
+set, a set of current values, and a set of previous values.  These are all
+needed so the subroutine can calculate things like the difference between this
+tick and the previous tick.
+
+The subroutines that extract the data from the set are compiled from
+expressions.  This gives significantly more power than just naming the values to
+fill the columns, because it allows the column's value to be calculated from
+whatever data is necessary, but avoids the need to write complicated and lengthy
+Perl code.
+
+innotop begins with a string of text that can look as simple as a value's name
+or as complicated as a full-fledged Perl expression.  It looks at each
+'bareword' token in the string and decides whether it's supposed to be a key
+into the $set hash.  A bareword is an unquoted value that isn't already
+surrounded by code-ish things like dollar signs or curly brackets.  If innotop
+decides that the bareword isn't a function or other valid Perl code, it converts
+it into a hash access.  After the whole string is processed, innotop compiles a
+subroutine, like this:
+
+ sub compute_column_value {
+    my ( $set, $cur, $pre ) = @_;
+    my $val = # EXPANDED STRING GOES HERE
+    return $val;
+ }
+
+Here's a concrete example, taken from the header table L<"q_header"> in L<"Q:
+Query List"> mode.  This expression calculates the qps, or Queries Per Second,
+column's values, from the values returned by SHOW STATUS:
+
+ Questions/Uptime_hires
+
+innotop decides both words are barewords, and transforms this expression into
+the following Perl code:
+
+ $set->{Questions}/$set->{Uptime_hires}
+
+When surrounded by the rest of the subroutine's code, this is executable Perl
+that calculates a high-resolution queries-per-second value.
+
+The arguments to the subroutine are named $set, $cur, and $pre.  In most cases,
+$set and $cur will be the same values.  However, if L<"status_inc"> is set, $cur
+will not be the same as $set, because $set will already contain values that are
+the incremental difference between $cur and $pre.
+
+Every column in innotop is computed by subroutines compiled in the same fashion.
+There is no difference between innotop's built-in columns and user-defined
+columns.  This keeps things consistent and predictable.
+
+=head2 TRANSFORMATIONS
+
+Transformations change how a value is rendered.  For example, they can take a
+number of seconds and display it in H:M:S format.  The following transformations
+are defined:
+
+=over
+
+=item commify
+
+Adds commas to large numbers every three decimal places.
+
+=item distill
+
+Distills SQL into verb-noun-noun format for quick comprehension.
+
+=item dulint_to_int
+
+Accepts two unsigned integers and converts them into a single longlong.  This is
+useful for certain operations with InnoDB, which uses two integers as
+transaction identifiers, for example.
+
+=item fuzzy_time
+
+Converts a number of seconds into a friendly, readable value like "1h35m".
+
+=item no_ctrl_char
+
+Removes quoted control characters from the value.  This is affected by the
+L<"charset"> configuration variable.
+
+This transformation only operates within quoted strings, for example, values to
+a SET clause in an UPDATE statement.  It will not alter the UPDATE statement,
+but will collapse the quoted string to [BINARY] or [TEXT], depending on the
+charset.
+
+=item percent
+
+Converts a number to a percentage by multiplying it by two, formatting it with
+L<"num_digits"> digits after the decimal point, and optionally adding a percent
+sign (see L<"show_percent">).
+
+=item secs_to_time
+
+Formats a number of seconds as time in days+hours:minutes:seconds format.
+
+=item set_precision
+
+Formats numbers with L<"num_digits"> number of digits after the decimal point.
+
+=item shorten
+
+Formats a number as a unit of 1024 (k/M/G/T) and with L<"num_digits"> number of
+digits after the decimal point.
+
+=back
+
+=head2 TABLE EDITOR
+
+The innotop table editor lets you customize tables with keystrokes.  You start
+the table editor with the '^' key.  If there's more than one table on the
+screen, it will prompt you to choose one of them.  Once you do, innotop will
+show you something like this:
+
+ Editing table definition for Buffer Pool.  Press ? for help, q to quit.
+
+ name               hdr          label                  src
+ cxn                CXN          Connection from which  cxn
+ buf_pool_size      Size         Buffer pool size       IB_bp_buf_poo
+ buf_free           Free Bufs    Buffers free in the b  IB_bp_buf_fre
+ pages_total        Pages        Pages total            IB_bp_pages_t
+ pages_modified     Dirty Pages  Pages modified (dirty  IB_bp_pages_m
+ buf_pool_hit_rate  Hit Rate     Buffer pool hit rate   IB_bp_buf_poo
+ total_mem_alloc    Memory       Total memory allocate  IB_bp_total_m
+ add_pool_alloc     Add'l Pool   Additional pool alloca  IB_bp_add_poo
+
+The first line shows which table you're editing, and reminds you again to press
+'?' for a list of key mappings.  The rest is a tabular representation of the
+table's columns, because that's likely what you're trying to edit.  However, you
+can edit more than just the table's columns; this screen can start the filter
+editor, color rule editor, and more.
+
+Each row in the display shows a single column in the table you're editing, along
+with a couple of its properties such as its header and source expression (see
+L<"EXPRESSIONS">).
+
+The key mappings are Vim-style, as in many other places.  Pressing 'j' and 'k'
+moves the highlight up or down.  You can then (d)elete or (e)dit the highlighted
+column.  You can also (a)dd a column to the table.  This actually just activates
+one of the columns already defined for the table; it prompts you to choose from
+among the columns available but not currently displayed.  Finally, you can
+re-order the columns with the '+' and '-' keys.
+
+You can do more than just edit the columns with the table editor, you can also
+edit other properties, such as the table's sort expression and group-by
+expression.  Press '?' to see the full list, of course.
+
+If you want to really customize and create your own column, as opposed to just
+activating a built-in one that's not currently displayed, press the (n)ew key,
+and innotop will prompt you for the information it needs:
+
+=over
+
+=item *
+
+The column name: this needs to be a word without any funny characters, e.g. just
+letters, numbers and underscores.
+
+=item *
+
+The column header: this is the label that appears at the top of the column, in
+the table header.  This can have spaces and funny characters, but be careful not
+to make it too wide and waste space on-screen.
+
+=item *
+
+The column's data source: this is an expression that determines what data from
+the source (see L<"TABLES">) innotop will put into the column.  This can just be
+the name of an item in the source, or it can be a more complex expression, as
+described in L<"EXPRESSIONS">.
+
+=back
+
+Once you've entered the required data, your table has a new column.  There is no
+difference between this column and the built-in ones; it can have all the same
+properties and behaviors.  innotop will write the column's definition to the
+configuration file, so it will persist across sessions.
+
+Here's an example: suppose you want to track how many times your slaves have
+retried transactions.  According to the MySQL manual, the
+Slave_retried_transactions status variable gives you that data: "The total
+number of times since startup that the replication slave SQL thread has retried
+transactions. This variable was added in version 5.0.4."  This is appropriate to
+add to the L<"slave_sql_status"> table.
+
+To add the column, switch to the replication-monitoring mode with the 'M' key,
+and press the '^' key to start the table editor.  When prompted, choose
+slave_sql_status as the table, then press 'n' to create the column.  Type
+'retries' as the column name, 'Retries' as the column header, and
+'Slave_retried_transactions' as the source.  Now the column is created, and you
+see the table editor screen again.  Press 'q' to exit the table editor, and
+you'll see your column at the end of the table.
+
+=head1 VARIABLE SETS
+
+Variable sets are used in L<"S: Variables & Status"> mode to define more easily
+what variables you want to monitor.  Behind the scenes they are compiled to a
+list of expressions, and then into a column list so they can be treated just
+like columns in any other table, in terms of data extraction and
+transformations.  However, you're protected from the tedious details by a syntax
+that ought to feel very natural to you: a SQL SELECT list.
+
+The data source for variable sets, and indeed the entire S mode, is the
+combination of SHOW STATUS, SHOW VARIABLES, and SHOW INNODB STATUS.  Imagine
+that you had a huge table with one column per variable returned from those
+statements.  That's the data source for variable sets.  You can now query this
+data source just like you'd expect.  For example:
+
+ Questions, Uptime, Questions/Uptime as QPS
+
+Behind the scenes innotop will split that variable set into three expressions,
+compile them and turn them into a table definition, then extract as usual.  This
+becomes a "variable set," or a "list of variables you want to monitor."
+
+innotop lets you name and save your variable sets, and writes them to the
+configuration file.  You can choose which variable set you want to see with the
+'c' key, or activate the next and previous sets with the '>' and '<' keys.
+There are many built-in variable sets as well, which should give you a good
+start for creating your own.  Press 'e' to edit the current variable set, or
+just to see how it's defined.  To create a new one, just press 'c' and type its
+name.
+
+You may want to use some of the functions listed in L<"TRANSFORMATIONS"> to help
+format the results.  In particular, L<"set_precision"> is often useful to limit
+the number of digits you see.  Extending the above example, here's how:
+
+ Questions, Uptime, set_precision(Questions/Uptime) as QPS
+
+Actually, this still needs a little more work.  If your L<"interval"> is less
+than one second, you might be dividing by zero because Uptime is incremental in
+this mode by default.  Instead, use Uptime_hires:
+
+ Questions, Uptime, set_precision(Questions/Uptime_hires) as QPS
+
+This example is simple, but it shows how easy it is to choose which variables
+you want to monitor.
+
+=head1 PLUGINS
+
+innotop has a simple but powerful plugin mechanism by which you can extend
+or modify its existing functionality, and add new functionality.  innotop's
+plugin functionality is event-based: plugins register themselves to be called
+when events happen.  They then have a chance to influence the event.
+
+An innotop plugin is a Perl module (.pm) file placed in innotop's L<"plugin_dir">
+directory.  On UNIX systems, you can place a symbolic link to the module instead
+of putting the actual file there.  innotop automatically discovers files named C<*.pm>.  If
+there is a corresponding entry in the L<"plugins"> configuration file section,
+innotop loads and activates the plugin.
+
+The module must conform to innotop's plugin interface.  Additionally, the source
+code of the module must be written in such a way that innotop can inspect the
+file and determine the package name and description.
+
+=head2 Package Source Convention
+
+innotop inspects the plugin module's source to determine the Perl package name.
+It looks for a line of the form "package Foo;" and if found, considers the
+plugin's package name to be Foo.  Of course the package name can be a valid Perl
+package name such as Foo::Bar, with double colons (::) and so on.
+
+It also looks for a description in the source code, to make the plugin editor
+more human-friendly.  The description is a comment line of the form "#
+description: Foo", where "Foo" is the text innotop will consider to be the
+plugin's description.
+
+=head2 Plugin Interface
+
+The innotop plugin interface is quite simple: innotop expects the plugin to be
+an object-oriented module it can call certain methods on.  The methods are
+
+=over
+
+=item new(%variables)
+
+This is the plugin's constructor.  It is passed a hash of innotop's variables,
+which it can manipulate (see L<"Plugin Variables">).  It must return a reference
+to the newly created plugin object.
+
+At construction time, innotop has only loaded the general configuration and
+created the default built-in variables with their default contents (which is
+quite a lot).  Therefore, the state of the program is exactly as in the innotop
+source code, plus the configuration variables from the L<"general"> section in
+the config file.
+
+If your plugin manipulates the variables, it is changing global data, which is
+shared by innotop and all plugins.  Plugins are loaded in the order they're
+listed in the config file.  Your plugin may load before or after another plugin,
+so there is a potential for conflict or interaction between plugins if they
+modify data other plugins use or modify.
+
+=item register_for_events()
+
+This method must return a list of events in which the plugin is interested, if
+any.  See L<"Plugin Events"> for the defined events.  If the plugin returns an
+event that's not defined, the event is ignored.
+
+=item event handlers
+
+The plugin must implement a method named the same as each event for which it has
+registered.  In other words, if the plugin returns qw(foo bar) from
+register_for_events(), it must have foo() and bar() methods.  These methods are
+callbacks for the events.  See L<"Plugin Events"> for more details about each
+event.
+
+=back
+
+=head2 Plugin Variables
+
+The plugin's constructor is passed a hash of innotop's variables, which it can
+manipulate.  It is probably a good idea if the plugin object saves a copy of it
+for later use.  The variables are defined in the innotop variable
+%pluggable_vars, and are as follows:
+
+=over
+
+=item action_for
+
+A hashref of key mappings.  These are innotop's global hot-keys.
+
+=item agg_funcs
+
+A hashref of functions that can be used for grouping.  See L<"GROUPING">.
+
+=item config
+
+The global configuration hash.
+
+=item connections
+
+A hashref of connection specifications.  These are just specifications of how to
+connect to a server.
+
+=item dbhs
+
+A hashref of innotop's database connections.  These are actual DBI connection
+objects.
+
+=item filters
+
+A hashref of filters applied to table rows.  See L<"FILTERS"> for more.
+
+=item modes
+
+A hashref of modes.  See L<"MODES"> for more.
+
+=item server_groups
+
+A hashref of server groups.  See L<"SERVER GROUPS">.
+
+=item tbl_meta
+
+A hashref of innotop's table meta-data, with one entry per table (see
+L<"TABLES"> for more information).
+
+=item trans_funcs
+
+A hashref of transformation functions.  See L<"TRANSFORMATIONS">.
+
+=item var_sets
+
+A hashref of variable sets.  See L<"VARIABLE SETS">.
+
+=back
+
+=head2 Plugin Events
+
+Each event is defined somewhere in the innotop source code.  When innotop runs
+that code, it executes the callback function for each plugin that expressed its
+interest in the event.  innotop passes some data for each event.  The events are
+defined in the %event_listener_for variable, and are as follows:
+
+=over
+
+=item extract_values($set, $cur, $pre, $tbl)
+
+This event occurs inside the function that extracts values from a data source.
+The arguments are the set of values, the current values, the previous values,
+and the table name.
+
+=item set_to_tbl
+
+Events are defined at many places in this subroutine, which is responsible for
+turning an arrayref of hashrefs into an arrayref of lines that can be printed to
+the screen.  The events all pass the same data: an arrayref of rows and the name
+of the table being created.  The events are set_to_tbl_pre_filter,
+set_to_tbl_pre_sort,set_to_tbl_pre_group, set_to_tbl_pre_colorize,
+set_to_tbl_pre_transform, set_to_tbl_pre_pivot, set_to_tbl_pre_create,
+set_to_tbl_post_create.
+
+=item draw_screen($lines)
+
+This event occurs inside the subroutine that prints the lines to the screen.
+$lines is an arrayref of strings.
+
+=back
+
+=head2 Simple Plugin Example
+
+The easiest way to explain the plugin functionality is probably with a simple
+example.  The following module adds a column to the beginning of every table and
+sets its value to 1.  (If you copy and paste this example code, be sure to remove
+the first space from each line; lines such as '# description' must not start with
+whitespace).
+
+ use strict;
+ use warnings FATAL => 'all';
+
+ package Innotop::Plugin::Example;
+ # description: Adds an 'example' column to every table
+
+ sub new {
+    my ( $class, %vars ) = @_;
+    # Store reference to innotop's variables in $self
+    my $self = bless { %vars }, $class;
+
+    # Design the example column
+    my $col = {
+       hdr   => 'Example',
+       just  => '',
+       dec   => 0,
+       num   => 1,
+       label => 'Example',
+       src   => 'example', # Get data from this column in the data source
+       tbl   => '',
+       trans => [],
+    };
+
+    # Add the column to every table.
+    my $tbl_meta = $vars{tbl_meta};
+    foreach my $tbl ( values %$tbl_meta ) {
+       # Add the column to the list of defined columns
+       $tbl->{cols}->{example} = $col;
+       # Add the column to the list of visible columns
+       unshift @{$tbl->{visible}}, 'example';
+    }
+
+    # Be sure to return a reference to the object.
+    return $self;
+ }
+
+ # I'd like to be called when a data set is being rendered into a table, please.
+ sub register_for_events {
+    my ( $self ) = @_;
+    return qw(set_to_tbl_pre_filter);
+ }
+
+ # This method will be called when the event fires.
+ sub set_to_tbl_pre_filter {
+    my ( $self, $rows, $tbl ) = @_;
+    # Set the example column's data source to the value 1.
+    foreach my $row ( @$rows ) {
+       $row->{example} = 1;
+    }
+ }
+
+ 1;
+
+=head2 Plugin Editor
+
+The plugin editor lets you view the plugins innotop discovered and activate or
+deactivate them.  Start the editor by pressing $ to start the configuration
+editor from any mode.  Press the 'p' key to start the plugin editor.  You'll see
+a list of plugins innotop discovered.  You can use the 'j' and 'k' keys to move
+the highlight to the desired one, then press the * key to toggle it active or
+inactive.  Exit the editor and restart innotop for the changes to take effect.
+
+=head1 SQL STATEMENTS
+
+innotop uses a limited set of SQL statements to retrieve data from MySQL for
+display.  The statements are customized depending on the server version against
+which they are executed; for example, on MySQL 5 and newer, INNODB_STATUS
+executes "SHOW ENGINE INNODB STATUS", while on earlier versions it executes
+"SHOW INNODB STATUS".  The statements are as follows:
+
+ Statement           SQL executed
+ =================== ===============================
+ INDEX_STATISTICS    SELECT * FROM INFORMATION_SCHEMA.INDEX_STATISTICS
+ INNODB_STATUS       SHOW [ENGINE] INNODB STATUS
+ KILL_CONNECTION     KILL
+ KILL_QUERY          KILL QUERY
+ OPEN_TABLES         SHOW OPEN TABLES
+ PROCESSLIST         SHOW FULL PROCESSLIST
+ SHOW_MASTER_LOGS    SHOW MASTER LOGS
+ SHOW_MASTER_STATUS  SHOW MASTER STATUS
+ SHOW_SLAVE_STATUS   SHOW SLAVE STATUS
+ SHOW_STATUS         SHOW [GLOBAL] STATUS
+ SHOW_VARIABLES      SHOW [GLOBAL] VARIABLES
+ TABLE_STATISTICS    SELECT * FROM INFORMATION_SCHEMA.TABLE_STATISTICS
+
+=head1 DATA SOURCES
+
+Each time innotop extracts values to create a table (see L<"EXPRESSIONS"> and
+L<"TABLES">), it does so from a particular data source.  Largely because of the
+complex data extracted from SHOW INNODB STATUS, this is slightly messy.  SHOW
+INNODB STATUS contains a mixture of single values and repeated values that form
+nested data sets.
+
+Whenever innotop fetches data from MySQL, it adds two extra bits to each set:
+cxn and Uptime_hires.  cxn is the name of the connection from which the data
+came.  Uptime_hires is a high-resolution version of the server's Uptime status
+variable, which is important if your L<"interval"> setting is sub-second.
+
+Here are the kinds of data sources from which data is extracted:
+
+=over
+
+=item STATUS_VARIABLES
+
+This is the broadest category, into which the most kinds of data fall.  It
+begins with the combination of SHOW STATUS and SHOW VARIABLES, but other sources
+may be included as needed, for example, SHOW MASTER STATUS and SHOW SLAVE
+STATUS, as well as many of the non-repeated values from SHOW INNODB STATUS.
+
+=item DEADLOCK_LOCKS
+
+This data is extracted from the transaction list in the LATEST DETECTED DEADLOCK
+section of SHOW INNODB STATUS.  It is nested two levels deep: transactions, then
+locks.
+
+=item DEADLOCK_TRANSACTIONS
+
+This data is from the transaction list in the LATEST DETECTED DEADLOCK
+section of SHOW INNODB STATUS.  It is nested one level deep.
+
+=item EXPLAIN
+
+This data is from the result set returned by EXPLAIN.
+
+=item INNODB_BLOCKED_BLOCKER
+
+This data is from the INFORMATION_SCHEMA tables related to InnoDB locks and
+the processlist.
+
+=item INNODB_TRANSACTIONS
+
+This data is from the TRANSACTIONS section of SHOW INNODB STATUS.
+
+=item IO_THREADS
+
+This data is from the list of threads in the FILE I/O section of SHOW INNODB
+STATUS.
+
+=item INNODB_LOCKS
+
+This data is from the TRANSACTIONS section of SHOW INNODB STATUS and is nested
+two levels deep.
+
+=item MASTER_SLAVE
+
+This data is from the combination of SHOW MASTER STATUS and SHOW SLAVE STATUS.
+
+=item OPEN_TABLES
+
+This data is from SHOW OPEN TABLES.
+
+=item PROCESSLIST
+
+This data is from SHOW FULL PROCESSLIST.
+
+=item PROCESSLIST_STATS
+
+This data is from SHOW FULL PROCESSLIST and computes stats such as the maximum time
+a user query has been running, and how many user queries are running. A "user
+query" excludes replication threads.
+
+=item OS_WAIT_ARRAY
+
+This data is from the SEMAPHORES section of SHOW INNODB STATUS and is nested one
+level deep.  It comes from the lines that look like this:
+
+ --Thread 1568861104 has waited at btr0cur.c line 424 ....
+
+=back
+
+=head1 MYSQL PRIVILEGES
+
+=over
+
+=item *
+
+You must connect to MySQL as a user who has the SUPER privilege for many of the
+functions.
+
+=item *
+
+If you don't have the SUPER privilege, you can still run some functions, but you
+won't necessarily see all the same data.
+
+=item *
+
+You need the PROCESS privilege to see the list of currently running queries in Q
+mode.
+
+=item *
+
+You need special privileges to start and stop slave servers.
+
+=item *
+
+You need appropriate privileges to create and drop the deadlock tables if needed
+(see L<"SERVER CONNECTIONS">).
+
+=back
+
+=head1 SYSTEM REQUIREMENTS
+
+You need Perl to run innotop, of course.  You also need a few Perl modules: DBI,
+DBD::MariaDB,  Term::ReadKey, and Time::HiRes.  These should be included with most
+Perl distributions, but in case they are not, I recommend using versions
+distributed with your operating system or Perl distribution, not from CPAN.
+Term::ReadKey in particular has been known to cause problems if installed from
+CPAN.
+
+If you have Term::ANSIColor, innotop will use it to format headers more readably
+and compactly.  (Under Microsoft Windows, you also need Win32::Console::ANSI for
+terminal formatting codes to be honored).  If you install Term::ReadLine,
+preferably Term::ReadLine::Gnu, you'll get nice auto-completion support.
+
+I run innotop on Gentoo GNU/Linux, Debian and Ubuntu, and I've had feedback from
+people successfully running it on Red Hat, CentOS, Solaris, and Mac OSX.  I
+don't see any reason why it won't work on other UNIX-ish operating systems, but
+I don't know for sure.  It also runs on Windows under ActivePerl without
+problem.
+
+innotop has been used on MySQL versions 3.23.58, 4.0.27, 4.1.0, 4.1.22, 5.0.26,
+5.1.15, and 5.2.3.  If it doesn't run correctly for you, that is a bug that
+should be reported.
+
+=head1 FILES
+
+$HOMEDIR/.innotop and/or /etc/innotop are used to store
+configuration information.  Files include the configuration file innotop.conf,
+the core_dump file which contains verbose error messages if L<"debug"> is
+enabled, and the plugins/ subdirectory.
+
+=head1 GLOSSARY OF TERMS
+

+
+=item tick
+
+A tick is a refresh event, when innotop re-fetches data from connections and
+displays it.

+\& innotop
+.Ve
+.PP
+To monitor InnoDB status information from a file:
+.PP
+.Vb 1
+\& innotop /var/log/mysql/mysqld.err

+.Ve
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+innotop monitors MySQL servers.  Each of its modes shows you a different aspect
+of what's happening in the server.  For example, there's a mode for monitoring
+replication, one for queries, and one for transactions.  innotop refreshes its
+data periodically, so you see an updating view.
+.PP
+innotop has lots of features for power users, but you can start and run it with
+virtually no configuration.  If you're just getting started, see
+\&\*(L"QUICK-START\*(R".  Press '?' at any time while running innotop for
+context-sensitive help.
+.SH "QUICK-START"
+.IX Header "QUICK-START"
+To start innotop, open a terminal or command prompt.  If you have installed
+innotop on your system, you should be able to just type \*(L"innotop\*(R" and press
+Enter; otherwise, you will need to change to innotop's directory and type \*(L"perl
+innotop\*(R".
+.PP
+With no options specified, innotop will attempt to connect to a MySQL server on
+localhost using mariadb_read_default_group=client for other connection
+parameters.  If you need to specify a different username and password, use the
+\&\-u and \-p options, respectively.  To monitor a MySQL database on another
+host, use the \-h option.
+.PP
+After you've connected, innotop should show you something like the following:
+.PP

+If your server is busy, you'll see more output.  Notice the first line on the
+screen, which tells you that readonly is set to true ([\s-1RO\s0]), what mode you're
+in and what server you're connected to.  You can change to other modes with
+keystrokes; press 'T' to switch to a list of InnoDB transactions, for example.
+.PP
+Press the '?' key to see what keys are active in the current mode.  You can
+press any of these keys and innotop will either take the requested action or
+prompt you for more input.  If your system has Term::ReadLine support, you can
+use \s-1TAB\s0 and other keys to auto-complete and edit input.
+.PP
+To quit innotop, press the 'q' key.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+innotop is mostly configured via its configuration file, but some of the
+configuration options can come from the command line.  You can also specify a
+file to monitor for InnoDB status output; see \*(L"\s-1MONITORING A FILE\*(R"\s0 for more
+details.
+.PP
+You can negate some options by prefixing the option name with \-\-no.  For
+example, \-\-noinc (or \-\-no\-inc) negates \*(L"\-\-inc\*(R".
+.IP "\-\-color" 4
+.IX Item "--color"
+Enable or disable terminal coloring.  Corresponds to the \*(L"color\*(R" config file
+setting.
+.IP "\-\-config" 4
+.IX Item "--config"
+Specifies a configuration file to read.  This option is non-sticky, that is to
+say it does not persist to the configuration file itself.
+.IP "\-\-count" 4
+.IX Item "--count"
+Refresh only the specified number of times (ticks) before exiting.  Each refresh
+is a pause for \*(L"interval\*(R" seconds, followed by requesting data from MySQL
+connections and printing it to the terminal.
+.IP "\-\-delay" 4
+.IX Item "--delay"
+Specifies the amount of time to pause between ticks (refreshes).  Corresponds to
+the configuration option \*(L"interval\*(R".
+.IP "\-\-help" 4
+.IX Item "--help"
+Print a summary of command-line usage and exit.
+.IP "\-\-host" 4
+.IX Item "--host"
+Host to connect to.
+.IP "\-\-inc" 4
+.IX Item "--inc"
+Specifies whether innotop should display absolute numbers or relative numbers
+(offsets from their previous values).  Corresponds to the configuration option
+\&\*(L"status_inc\*(R".
+.IP "\-\-mode" 4
+.IX Item "--mode"
+Specifies the mode in which innotop should start.  Corresponds to the
+configuration option \*(L"mode\*(R".
+.IP "\-\-nonint" 4
+.IX Item "--nonint"
+Enable non-interactive operation.  See \*(L"NON-INTERACTIVE \s-1OPERATION\*(R"\s0 for more.
+.IP "\-\-password" 4
+.IX Item "--password"
+Password to use for connection.
+.IP "\-\-port" 4

+.IX Item "--version"
+Output version information and exit.
+.IP "\-\-write" 4
+.IX Item "--write"
+Sets the configuration option \*(L"readonly\*(R" to 0, making innotop write the
+running configuration to ~/.innotop/innotop.conf on exit, if no configuration
+file was loaded at start-up.
+.SH "HOTKEYS"
+.IX Header "HOTKEYS"
+innotop is interactive, and you control it with key-presses.
+.IP "\(bu" 4
+Uppercase keys switch between modes.
+.IP "\(bu" 4
+Lowercase keys initiate some action within the current mode.

+.PP
+Press '?' at any time to see the currently active keys and what they do.
+.SH "MODES"
+.IX Header "MODES"
+Each of innotop's modes retrieves and displays a particular type of data from
+the servers you're monitoring.  You switch between modes with uppercase keys.
+The following is a brief description of each mode, in alphabetical order.  To
+switch to the mode, press the key listed in front of its heading in the
+following list:
+.IP "A: Health Dashboard" 4
+.IX Item "A: Health Dashboard"
+This mode displays a single table with one row per monitored server. The
+columns show essential overview information about the server's health, and
+coloration rules show whether replication is running or if there are any very
+long-running queries or excessive replication delay.
+.IP "B: InnoDB Buffers" 4
+.IX Item "B: InnoDB Buffers"
+This mode displays information about the InnoDB buffer pool, page statistics,
+insert buffer, and adaptive hash index.  The data comes from \s-1SHOW INNODB STATUS.\s0
+.Sp
+This mode contains the \*(L"buffer_pool\*(R", \*(L"page_statistics\*(R",
+\&\*(L"insert_buffers\*(R", and \*(L"adaptive_hash_index\*(R" tables by default.
+.IP "C: Command Summary" 4
+.IX Item "C: Command Summary"
+This mode is similar to mytop's Command Summary mode.  It shows the
+\&\*(L"cmd_summary\*(R" table, which looks something like the following:
+.Sp
+.Vb 8
+\& Command Summary (? for help) localhost, 25+07:16:43, 2.45 QPS, 3 thd, 5.0.40

+\& Select_range_check            0   0.00%          0    0.00%
+.Ve
+.Sp
+The command summary table is built by extracting variables from
+\&\*(L"\s-1STATUS_VARIABLES\*(R"\s0.  The variables must be numeric and must match the prefix
+given by the \*(L"cmd_filter\*(R" configuration variable.  The variables are then
+sorted by value descending and compared to the last variable, as shown above.
+The percentage columns are percentage of the total of all variables in the
+table, so you can see the relative weight of the variables.
+.Sp
+The example shows what you see if the prefix is \*(L"Select_\*(R".  The default
+prefix is \*(L"Com_\*(R".  You can choose a prefix with the 's' key.
+.Sp
+It's rather like running \s-1SHOW VARIABLES LIKE \s0\*(L"prefix%\*(R" with memory and
+nice formatting.
+.Sp
+Values are aggregated across all servers.  The Pct columns are not correctly
+aggregated across multiple servers.  This is a known limitation of the grouping
+algorithm that may be fixed in the future.
+.IP "D: InnoDB Deadlocks" 4
+.IX Item "D: InnoDB Deadlocks"
+This mode shows the transactions involved in the last InnoDB deadlock.  A second
+table shows the locks each transaction held and waited for.  A deadlock is
+caused by a cycle in the waits-for graph, so there should be two locks held and
+one waited for unless the deadlock information is truncated.
+.Sp
+InnoDB puts deadlock information before some other information in the \s-1SHOW
+INNODB STATUS\s0 output.  If there are a lot of locks, the deadlock information can
+grow very large, and there is a limit on the size of the \s-1SHOW INNODB
+STATUS\s0 output.  A large deadlock can fill the entire output, or even be
+truncated, and prevent you from seeing other information at all.  If you are
+running innotop in another mode, for example T mode, and suddenly you don't see
+anything, you might want to check and see if a deadlock has wiped out the data
+you need.
+.Sp
+If it has, you can create a small deadlock to replace the large one.  Use the
+\&'w' key to 'wipe' the large deadlock with a small one.  This will not work
+unless you have defined a deadlock table for the connection (see \*(L"\s-1SERVER
+CONNECTIONS\*(R"\s0).
+.Sp
+You can also configure innotop to automatically detect when a large deadlock
+needs to be replaced with a small one (see \*(L"auto_wipe_dl\*(R").
+.Sp
+This mode displays the \*(L"deadlock_transactions\*(R" and \*(L"deadlock_locks\*(R" tables
+by default.
+.IP "F: InnoDB Foreign Key Errors" 4
+.IX Item "F: InnoDB Foreign Key Errors"
+This mode shows the last InnoDB foreign key error information, such as the
+table where it happened, when and who and what query caused it, and so on.
+.Sp
+InnoDB has a huge variety of foreign key error messages, and many of them are
+just hard to parse.  innotop doesn't always do the best job here, but there's
+so much code devoted to parsing this messy, unparseable output that innotop is
+likely never to be perfect in this regard.  If innotop doesn't show you what
+you need to see, just look at the status text directly.
+.Sp
+This mode displays the \*(L"fk_error\*(R" table by default.
+.IP "I: InnoDB I/O Info" 4
+.IX Item "I: InnoDB I/O Info"
+This mode shows InnoDB's I/O statistics, including the I/O threads, pending I/O,
+file I/O miscellaneous, and log statistics.  It displays the \*(L"io_threads\*(R",
+\&\*(L"pending_io\*(R", \*(L"file_io_misc\*(R", and \*(L"log_statistics\*(R" tables by default.
+.IP "K: InnoDB Lock Waits" 4
+.IX Item "K: InnoDB Lock Waits"
+This mode shows information from InnoDB plugin's transaction and locking tables.
+You can use it to find when a transaction is waiting for another, and kill the
+blocking transaction. It displays the "innodb_blocked_blocker" table.
+.IP "L: Locks" 4
+.IX Item "L: Locks"
+This mode shows information about current locks.  At the moment only InnoDB
+locks are supported, and by default you'll only see locks for which transactions
+are waiting.  This information comes from the \s-1TRANSACTIONS\s0 section of the InnoDB
+status text.  If you have a very busy server, you may have frequent lock waits;
+it helps to be able to see which tables and indexes are the \*(L"hot spot\*(R" for
+locks.  If your server is running pretty well, this mode should show nothing.
+.Sp
+You can configure MySQL and innotop to monitor not only locks for which a
+transaction is waiting, but those currently held, too.  You can do this with the
+InnoDB Lock Monitor (<http://dev.mysql.com/doc/en/innodb\-monitor.html>).  It's
+not documented in the MySQL manual, but creating the lock monitor with the
+following statement also affects the output of \s-1SHOW INNODB STATUS,\s0 which innotop
+uses:
+.Sp
+.Vb 1
+\&  CREATE TABLE innodb_lock_monitor(a int) ENGINE=INNODB;
+.Ve
+.Sp
+This causes InnoDB to print its output to the MySQL file every 16 seconds or so,
+as stated in the manual, but it also makes the normal \s-1SHOW INNODB STATUS\s0 output
+include lock information, which innotop can parse and display (that's the
+undocumented feature).
+.Sp
+This means you can do what may have seemed impossible: to a limited extent
+(InnoDB truncates some information in the output), you can see which transaction
+holds the locks something else is waiting for.  You can also enable and disable
+the InnoDB Lock Monitor with the key mappings in this mode.
+.Sp
+This mode displays the \*(L"innodb_locks\*(R" table by default.  Here's a sample of
+the screen when one connection is waiting for locks another connection holds:
+.Sp
+.Vb 7
+\& _\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_ InnoDB Locks _\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_\|_

+\& localhost  12  RECORD        1  00:10   00:10  X     test  t1     PRIMARY
+\& localhost  12  TABLE         0  00:10   00:10  IX    test  t1

+\& localhost  11  RECORD        0  00:00   00:25  X     test  t1     PRIMARY
+.Ve
+.Sp
+You can see the first connection, \s-1ID 12,\s0 is waiting for a lock on the \s-1PRIMARY\s0
+key on test.t1, and has been waiting for 10 seconds.  The second connection
+isn't waiting, because the Waiting column is 0, but it holds locks on the same
+index.  That tells you connection 11 is blocking connection 12.
+.IP "M: Master/Slave Replication Status" 4
+.IX Item "M: Master/Slave Replication Status"
+This mode shows the output of \s-1SHOW SLAVE STATUS\s0 and \s-1SHOW MASTER STATUS\s0 in three
+tables.  The first two divide the slave's status into \s-1SQL\s0 and I/O thread status,
+and the last shows master status.  Filters are applied to eliminate non-slave
+servers from the slave tables, and non-master servers from the master table.
+.Sp
+This mode displays the \*(L"slave_sql_status\*(R", \*(L"slave_io_status\*(R", and
+\&\*(L"master_status\*(R" tables by default.
+.IP "O: Open Tables" 4
+.IX Item "O: Open Tables"
+This section comes from MySQL's \s-1SHOW OPEN TABLES\s0 command.  By default it is
+filtered to show tables which are in use by one or more queries, so you can
+get a quick look at which tables are 'hot'.  You can use this to guess which
+tables might be locked implicitly.
+.Sp
+This mode displays the \*(L"open_tables\*(R" mode by default.
+.IP "U: User Statistics" 4
+.IX Item "U: User Statistics"
+This mode displays data that's available in Percona's enhanced version of MySQL
+(also known as Percona Server with XtraDB).  Specifically, it makes it easy to
+enable and disable the so-called \*(L"user statistics.\*(R"  This feature gathers stats
+on clients, threads, users, tables, and indexes and makes them available as
+\&\s-1INFORMATION_SCHEMA\s0 tables.  These are invaluable for understanding what your
+server is doing.  They are also available in MariaDB.
+.Sp
+The statistics supported so far are only from the \s-1TABLE_STATISTICS\s0 and
+\&\s-1INDEX_STATISTICS\s0 tables added by Percona.  There are three views: one of table stats,
+one of index stats (which can be aggregated with the = key), and one of both.
+.Sp
+The server doesn't gather these stats by default.  You have to set the variable
+userstat_running to turn it on.  You can do this easily with innotop from U mode,
+with the 's' key.
+.IP "Q: Query List" 4
+.IX Item "Q: Query List"
+This mode displays the output from \s-1SHOW FULL PROCESSLIST,\s0 much like \fBmytop\fR's
+query list mode.  This mode does \fBnot\fR show InnoDB-related information.  This
+is probably one of the most useful modes for general usage.
+.Sp
+There is an informative header that shows general status information about
+your server.  You can toggle it on and off with the 'h' key.  By default,
+innotop hides inactive processes and its own process.  You can toggle these on
+and off with the 'i' and 'a' keys.
+.Sp
+You can \s-1EXPLAIN\s0 a query from this mode with the 'e' key.  This displays the
+query's full text, the results of \s-1EXPLAIN,\s0 and in newer MySQL versions, even
+the optimized query resulting from \s-1EXPLAIN EXTENDED. \s0 innotop also tries to
+rewrite certain queries to make them EXPLAIN-able.  For example, \s-1INSERT/SELECT\s0
+statements are rewritable.
+.Sp
+This mode displays the \*(L"q_header\*(R" and \*(L"processlist\*(R" tables by default.
+.IP "R: InnoDB Row Operations and Semaphores" 4
+.IX Item "R: InnoDB Row Operations and Semaphores"
+This mode shows InnoDB row operations, row operation miscellaneous, semaphores,
+and information from the wait array.  It displays the \*(L"row_operations\*(R",
+\&\*(L"row_operation_misc\*(R", \*(L"semaphores\*(R", and \*(L"wait_array\*(R" tables by default.
+.IP "S: Variables & Status" 4
+.IX Item "S: Variables & Status"
+This mode calculates statistics, such as queries per second, and prints them out
+in several different styles.  You can show absolute values, or incremental values
+between ticks.
+.Sp
+You can switch between the views by pressing a key.  The 's' key prints a
+single line each time the screen updates, in the style of \fBvmstat\fR.  The 'g'
+key changes the view to a graph of the same numbers, sort of like \fBtload\fR.
+The 'v' key changes the view to a pivoted table of variable names on the left,
+with successive updates scrolling across the screen from left to right.  You can
+choose how many updates to put on the screen with the \*(L"num_status_sets\*(R"
+configuration variable.
+.Sp
+Headers may be abbreviated to fit on the screen in interactive operation.  You
+choose which variables to display with the 'c' key, which selects from
+predefined sets, or lets you create your own sets.  You can edit the current set
+with the 'e' key.
+.Sp
+This mode doesn't really display any tables like other modes.  Instead, it uses
+a table definition to extract and format the data, but it then transforms the
+result in special ways before outputting it.  It uses the \*(L"var_status\*(R" table
+definition for this.
+.IP "T: InnoDB Transactions" 4
+.IX Item "T: InnoDB Transactions"
+This mode shows transactions from the InnoDB monitor's output, in \fBtop\fR\-like
+format.  This mode is the reason I wrote innotop.
+.Sp
+You can kill queries or processes with the 'k' and 'x' keys, and \s-1EXPLAIN\s0 a query
+with the 'e' or 'f' keys.  InnoDB doesn't print the full query in transactions,
+so explaining may not work right if the query is truncated.
+.Sp
+The informational header can be toggled on and off with the 'h' key.  By
+default, innotop hides inactive transactions and its own transaction.  You can
+toggle this on and off with the 'i' and 'a' keys.
+.Sp
+This mode displays the \*(L"t_header\*(R" and \*(L"innodb_transactions\*(R" tables by
+default.
+.SH "INNOTOP STATUS"
+.IX Header "INNOTOP STATUS"
+The first line innotop displays is a \*(L"status bar\*(R" of sorts.  What it contains
+depends on the mode you're in, and what servers you're monitoring.  The first
+few words are always [\s-1RO\s0] (if readonly is set to 1), the innotop mode, such as
+\&\*(L"InnoDB Txns\*(R" for T mode, followed by a reminder to press '?' for help at any
+time.
+.SS "\s-1ONE SERVER\s0"
+.IX Subsection "ONE SERVER"
+The simplest case is when you're monitoring a single server.  In this case, the
+name of the connection is next on the status line.  This is the name you gave
+when you created the connection \*(-- most likely the MySQL server's hostname.
+This is followed by the server's uptime.
+.PP
+If you're in an InnoDB mode, such as T or B, the next word is \*(L"InnoDB\*(R" followed
+by some information about the \s-1SHOW INNODB STATUS\s0 output used to render the
+screen.  The first word is the number of seconds since the last \s-1SHOW INNODB
+STATUS,\s0 which InnoDB uses to calculate some per-second statistics.  The next is
+a smiley face indicating whether the InnoDB output is truncated.  If the smiley
+face is a :\-), all is well; there is no truncation.  A :^| means the transaction
+list is so long, InnoDB has only printed out some of the transactions.  Finally,
+a frown :\-( means the output is incomplete, which is probably due to a deadlock
+printing too much lock information (see \*(L"D: InnoDB Deadlocks\*(R").
+.PP
+The next two words indicate the server's queries per second (\s-1QPS\s0) and how many
+threads (connections) exist.  Finally, the server's version number is the last
+thing on the line.
+.SS "\s-1MULTIPLE SERVERS\s0"
+.IX Subsection "MULTIPLE SERVERS"
+If you are monitoring multiple servers (see \*(L"\s-1SERVER CONNECTIONS\*(R"\s0), the status
+line does not show any details about individual servers.  Instead, it shows the
+names of the connections that are active.  Again, these are connection names you
+specified, which are likely to be the server's hostname.  A connection that has
+an error is prefixed with an exclamation point.
+.PP
+If you are monitoring a group of servers (see \*(L"\s-1SERVER GROUPS\*(R"\s0), the status
+line shows the name of the group.  If any connection in the group has an
+error, the group's name is followed by the fraction of the connections that
+don't have errors.
+.PP
+See \*(L"\s-1ERROR HANDLING\*(R"\s0 for more details about innotop's error handling.
+.SS "\s-1MONITORING A FILE\s0"
+.IX Subsection "MONITORING A FILE"
+If you give a filename on the command line, innotop will not connect to \s-1ANY\s0
+servers at all.  It will watch the specified file for InnoDB status output and
+use that as its data source.  It will always show a single connection called
+\&'file'.  And since it can't connect to a server, it can't determine how long the
+server it's monitoring has been up; so it calculates the server's uptime as time
+since innotop started running.
+.SH "SERVER ADMINISTRATION"
+.IX Header "SERVER ADMINISTRATION"
+While innotop is primarily a monitor that lets you watch and analyze your
+servers, it can also send commands to servers.  The most frequently useful
+commands are killing queries and stopping or starting slaves.
+.PP
+You can kill a connection, or in newer versions of MySQL kill a query but not a
+connection, from \*(L"Q: Query List\*(R" and \*(L"T: InnoDB Transactions\*(R" modes.
+Press 'k' to issue a \s-1KILL\s0 command, or 'x' to issue a \s-1KILL QUERY\s0 command.
+innotop will prompt you for the server and/or connection \s-1ID\s0 to kill (innotop
+does not prompt you if there is only one possible choice for any input).
+innotop pre-selects the longest-running query, or the oldest connection.
+Confirm the command with 'y'.
+.PP
+In \*(L"Slave Replication Status\*(R"\*(L" in \*(R"M: Master mode, you can start and stop slaves
+with the 'a' and 'o' keys, respectively.  You can send these commands to many
+slaves at once.  innotop fills in a default command of \s-1START SLAVE\s0 or \s-1STOP SLAVE\s0
+for you, but you can actually edit the command and send anything you wish, such
+as \s-1SET GLOBAL\s0 SQL_SLAVE_SKIP_COUNTER=1 to make the slave skip one binlog event
+when it starts.
+.PP
+You can also ask innotop to calculate the earliest binlog in use by any slave
+and issue a \s-1PURGE MASTER LOGS\s0 on the master.  Use the 'b' key for this.  innotop
+will prompt you for a master to run the command on, then prompt you for the
+connection names of that master's slaves (there is no way for innotop to
+determine this reliably itself).  innotop will find the minimum binlog in use by
+these slave connections and suggest it as the argument to \s-1PURGE MASTER LOGS.\s0
+.PP
+in \*(L"U: User Statistics\*(R" mode, you can use the 's' key to start and stop
+the collection of the statistics data for \s-1TABLE_STATISTICS\s0 and similar.
+.SH "SERVER CONNECTIONS"
+.IX Header "SERVER CONNECTIONS"
+When you create a server connection using '@', innotop asks you for a series of
+inputs, as follows:
+.IP "\s-1DSN\s0" 4
+.IX Item "DSN"
+A \s-1DSN\s0 is a Data Source Name, which is the initial argument passed to the \s-1DBI\s0
+module for connecting to a server.  It is usually of the form
+.Sp
+.Vb 1
+\& DBI:MariaDB:;mariadb_read_default_group=mysql;host=HOSTNAME
+.Ve
+.Sp
+Since this \s-1DSN\s0 is passed to the DBD::MariaDB driver, you should read the driver's
+documentation at <https://metacpan.org/pod/DBD::MariaDB> for
+the exact details on all the options you can pass the driver in the \s-1DSN. \s0 You
+can read more about \s-1DBI\s0 at <http://dbi.perl.org/docs/>, and especially at
+<http://search.cpan.org/~timb/DBI/DBI.pm>.
+.Sp
+The mariadb_read_default_group=mysql option lets the \s-1DBD\s0 driver read your MySQL
+options files, such as ~/.my.cnf on UNIX-ish systems.  You can use this to avoid
+specifying a username or password for the connection.
+.IP "InnoDB Deadlock Table" 4
+.IX Item "InnoDB Deadlock Table"
+This optional item tells innotop a table name it can use to deliberately create
+a small deadlock (see \*(L"D: InnoDB Deadlocks\*(R").  If you specify this option,
+you just need to be sure the table doesn't exist, and that innotop can create
+and drop the table with the InnoDB storage engine.  You can safely omit or just
+accept the default if you don't intend to use this.
+.IP "Username" 4
+.IX Item "Username"
+innotop will ask you if you want to specify a username.  If you say 'y', it will
+then prompt you for a user name.  If you have a MySQL option file that specifies
+your username, you don't have to specify a username.
+.Sp
+The username defaults to your login name on the system you're running innotop on.
+.IP "Password" 4
+.IX Item "Password"
+innotop will ask you if you want to specify a password.  Like the username, the
+password is optional, but there's an additional prompt that asks if you want to
+save the password in the innotop configuration file.  If you don't save it in
+the configuration file, innotop will prompt you for a password each time it
+starts.  Passwords in the innotop configuration file are saved in plain text,
+not encrypted in any way.
+.PP
+Once you finish answering these questions, you should be connected to a server.
+But innotop isn't limited to monitoring a single server; you can define many
+server connections and switch between them by pressing the '@' key.  See
+\&\*(L"\s-1SWITCHING BETWEEN CONNECTIONS\*(R"\s0.
+.SH "SERVER GROUPS"
+.IX Header "SERVER GROUPS"
+If you have multiple MySQL instances, you can put them into named groups, such
+as 'all', 'masters', and 'slaves', which innotop can monitor all together.
+.PP
+You can choose which group to monitor with the '#' key, and you can press the
+\&\s-1TAB\s0 key to switch to the next group.  If you're not currently monitoring a
+group, pressing \s-1TAB\s0 selects the first group.
+.PP
+To create a group, press the '#' key and type the name of your new group, then
+type the names of the connections you want the group to contain.
+.SH "SWITCHING BETWEEN CONNECTIONS"
+.IX Header "SWITCHING BETWEEN CONNECTIONS"
+innotop lets you quickly switch which servers you're monitoring.  The most basic
+way is by pressing the '@' key and typing the name(s) of the connection(s) you
+want to use.  This setting is per-mode, so you can monitor different connections
+in each mode, and innotop remembers which connections you choose.
+.PP
+You can quickly switch to the 'next' connection in alphabetical order with the
+\&'n' key.  If you're monitoring a server group (see \*(L"\s-1SERVER GROUPS\*(R"\s0) this will
+switch to the first connection.
+.PP
+You can also type many connection names, and innotop will fetch and display data
+from them all.  Just separate the connection names with spaces, for example
+\&\*(L"server1 server2.\*(R"  Again, if you type the name of a connection that doesn't
+exist, innotop will prompt you for connection information and create the
+connection.
+.PP
+Another way to monitor multiple connections at once is with server groups.  You
+can use the \s-1TAB\s0 key to switch to the 'next' group in alphabetical order, or if
+you're not monitoring any groups, \s-1TAB\s0 will switch to the first group.
+.PP
+innotop does not fetch data in parallel from connections, so if you are
+monitoring a large group or many connections, you may notice increased delay
+between ticks.
+.PP
+When you monitor more than one connection, innotop's status bar changes.  See
+\&\*(L"\s-1INNOTOP STATUS\*(R"\s0.
+.SH "ERROR HANDLING"
+.IX Header "ERROR HANDLING"
+Error handling is not that important when monitoring a single connection, but is
+crucial when you have many active connections.  A crashed server or lost
+connection should not crash innotop.  As a result, innotop will continue to run
+even when there is an error; it just won't display any information from the
+connection that had an error.  Because of this, innotop's behavior might confuse
+you.  It's a feature, not a bug!
+.PP
+innotop does not continue to query connections that have errors, because they
+may slow innotop and make it hard to use, especially if the error is a problem
+connecting and causes a long time-out.  Instead, innotop retries the connection
+occasionally to see if the error still exists.  If so, it will wait until some
+point in the future.  The wait time increases in ticks as the Fibonacci series,
+so it tries less frequently as time passes.
+.PP
+Since errors might only happen in certain modes because of the \s-1SQL\s0 commands
+issued in those modes, innotop keeps track of which mode caused the error.  If
+you switch to a different mode, innotop will retry the connection instead of
+waiting.
+.PP
+By default innotop will display the problem in red text at the bottom of the
+first table on the screen.  You can disable this behavior with the
+\&\*(L"show_cxn_errors_in_tbl\*(R" configuration option, which is enabled by default.
+If the \*(L"debug\*(R" option is enabled, innotop will display the error at the
+bottom of every table, not just the first.  And if \*(L"show_cxn_errors\*(R" is
+enabled, innotop will print the error text to \s-1STDOUT\s0 as well.  Error messages
+might only display in the mode that caused the error, depending on the mode and
+whether innotop is avoiding querying that connection.
+.SH "NON-INTERACTIVE OPERATION"
+.IX Header "NON-INTERACTIVE OPERATION"
+You can run innotop in non-interactive mode, in which case it is entirely
+controlled from the configuration file and command-line options.  To start
+innotop in non-interactive mode, give the L\*(L"<\-\-nonint\*(R"> command-line option.
+This changes innotop's behavior in the following ways:
+.IP "\(bu" 4
+Certain Perl modules are not loaded.  Term::Readline is not loaded, since
+innotop doesn't prompt interactively.  Term::ANSIColor and Win32::Console::ANSI
+modules are not loaded.  Term::ReadKey is still used, since innotop may have to
+prompt for connection passwords when starting up.
+.IP "\(bu" 4
+innotop does not clear the screen after each tick.
+.IP "\(bu" 4
+innotop does not persist any changes to the configuration file.
+.IP "\(bu" 4
+If \*(L"\-\-count\*(R" is given and innotop is in incremental mode (see \*(L"status_inc\*(R"
+and \*(L"\-\-inc\*(R"), innotop actually refreshes one more time than specified so it
+can print incremental statistics.  This suppresses output during the first
+tick, so innotop may appear to hang.
+.IP "\(bu" 4
+innotop only displays the first table in each mode.  This is so the output can
+be easily processed with other command-line utilities such as awk and sed.  To
+change which tables display in each mode, see \*(L"\s-1TABLES\*(R"\s0.  Since \*(L"Q: Query
+List\*(R" mode is so important, innotop automatically disables the \*(L"q_header\*(R"
+table.  This ensures you'll see the \*(L"processlist\*(R" table, even if you have
+innotop configured to show the q_header table during interactive operation.
+Similarly, in \*(L"T: InnoDB Transactions\*(R" mode, the \*(L"t_header\*(R" table is
+suppressed so you see only the \*(L"innodb_transactions\*(R" table.
+.IP "\(bu" 4
+All output is tab-separated instead of being column-aligned with whitespace, and
+innotop prints the full contents of each table instead of only printing one
+screenful at a time.
+.IP "\(bu" 4
+innotop only prints column headers once instead of every tick (see
+\&\*(L"hide_hdr\*(R").  innotop does not print table captions (see
+\&\*(L"display_table_captions\*(R").  innotop ensures there are no empty lines in the
+output.
+.IP "\(bu" 4
+innotop does not honor the \*(L"shorten\*(R" transformation, which normally shortens
+some numbers to human-readable formats.
+.IP "\(bu" 4
+innotop does not print a status line (see \*(L"\s-1INNOTOP STATUS\*(R"\s0).
+.SH "CONFIGURING"
+.IX Header "CONFIGURING"
+Nearly everything about innotop is configurable.  Most things are possible to
+change with built-in commands, but you can also edit the configuration file.
+.PP
+While running innotop, press the '$' key to bring up the configuration editing
+dialog.  Press another key to select the type of data you want to edit:
+.IP "S: Statement Sleep Times" 4
+.IX Item "S: Statement Sleep Times"
+Edits \s-1SQL\s0 statement sleep delays, which make innotop pause for the specified
+amount of time after executing a statement.  See \*(L"\s-1SQL STATEMENTS\*(R"\s0 for a
+definition of each statement and what it does.  By default innotop does not
+delay after any statements.
+.Sp
+This feature is included so you can customize the side-effects caused by
+monitoring your server.  You may not see any effects, but some innotop users
+have noticed that certain MySQL versions under very high load with InnoDB
+enabled take longer than usual to execute \s-1SHOW GLOBAL STATUS. \s0 If innotop calls
+\&\s-1SHOW FULL PROCESSLIST\s0 immediately afterward, the processlist contains more
+queries than the machine actually averages at any given moment.  Configuring
+innotop to pause briefly after calling \s-1SHOW GLOBAL STATUS\s0 alleviates this
+effect.
+.Sp
+Sleep times are stored in the \*(L"stmt_sleep_times\*(R" section of the configuration
+file.  Fractional-second sleeps are supported, subject to your hardware's
+limitations.
+.IP "c: Edit Columns" 4
+.IX Item "c: Edit Columns"
+Starts the table editor on one of the displayed tables.  See \*(L"\s-1TABLE EDITOR\*(R"\s0.
+An alternative way to start the table editor without entering the configuration
+dialog is with the '^' key.
+.IP "g: General Configuration" 4
+.IX Item "g: General Configuration"
+Starts the configuration editor to edit global and mode-specific configuration
+variables (see \*(L"\s-1MODES\*(R"\s0).  innotop prompts you to choose a variable from among
+the global and mode-specific ones depending on the current mode.

+.SH "CONFIGURATION FILE"
+.IX Header "CONFIGURATION FILE"
+innotop's default configuration file locations are \f(CW$HOME\fR/.innotop and
+/etc/innotop/innotop.conf, and they are looked for in that order.  If the first
+configuration file exists, the second will not be processed.  Those can be
+overridden with the \*(L"\-\-config\*(R" command-line option.  You can edit it by hand
+safely, however innotop reads the configuration file when it starts, and, if
+readonly is set to 0, writes it out again when it exits.  Thus, if readonly is
+set to 0, any changes you make by hand while innotop is running will be lost.
+.PP
+innotop doesn't store its entire configuration in the configuration file.  It
+has a huge set of default configuration values that it holds only in memory,
+and the configuration file only overrides these defaults.  When you customize a
+default setting, innotop notices, and then stores the customizations into the
+file.  This keeps the file size down, makes it easier to edit, and makes
+upgrades easier.
+.PP
+A configuration file is read-only be default.  You can override that with
+\&\*(L"\-\-write\*(R".  See \*(L"readonly\*(R".
+.PP
+The configuration file is arranged into sections like an \s-1INI\s0 file.  Each
+section begins with [section\-name] and ends with [/section\-name].  Each
+section's entries have a different syntax depending on the data they need to
+store.  You can put comments in the file; any line that begins with a #
+character is a comment.  innotop will not read the comments, so it won't write
+them back out to the file when it exits.  Comments in read-only configuration
+files are still useful, though.
+.PP
+The first line in the file is innotop's version number.  This lets innotop
+notice when the file format is not backwards-compatible, and upgrade smoothly
+without destroying your customized configuration.
+.PP
+The following list describes each section of the configuration file and the data
+it contains:
+.IP "general" 4
+.IX Item "general"
+The 'general' section contains global configuration variables and variables that
+may be mode-specific, but don't belong in any other section.  The syntax is a
+simple key=value list.  innotop writes a comment above each value to help you
+edit the file by hand.

+Instructs innotop to automatically wipe large deadlocks when it notices them.
+When this happens you may notice a slight delay.  At the next tick, you will
+usually see the information that was being truncated by the large deadlock.
+.IP "charset" 4
+.IX Item "charset"
+Specifies what kind of characters to allow through the \*(L"no_ctrl_char\*(R"
+transformation.  This keeps non-printable characters from confusing a
+terminal when you monitor queries that contain binary data, such as images.
+.Sp
+The default is 'ascii', which considers anything outside normal \s-1ASCII\s0 to be a
+control character.  The other allowable values are 'unicode' and 'none'.  'none'

+Whether terminal coloring is permitted.
+.IP "cxn_timeout" 4
+.IX Item "cxn_timeout"
+On MySQL versions 4.0.3 and newer, this variable is used to set the connection's
+timeout, so MySQL doesn't close the connection if it is not used for a while.
+This might happen because a connection isn't monitored in a particular mode, for
+example.
+.IP "debug" 4
+.IX Item "debug"
+This option enables more verbose errors and makes innotop more strict in some

+innotop displays a table caption above most tables.  This variable suppresses or
+shows captions on all tables globally.  Some tables are configured with the
+hide_caption property, which overrides this.
+.IP "global" 4
+.IX Item "global"
+Whether to show \s-1GLOBAL\s0 variables and status.  innotop only tries to do this on
+servers which support the \s-1GLOBAL\s0 option to \s-1SHOW VARIABLES\s0 and \s-1SHOW STATUS. \s0 In
+some MySQL versions, you need certain privileges to do this; if you don't have

+.SH "CUSTOMIZING"
+.IX Header "CUSTOMIZING"
+You can customize innotop a great deal.  For example, you can:
+.IP "\(bu" 4
+Choose which tables to display, and in what order.
+.IP "\(bu" 4
+Choose which columns are in those tables, and create new columns.
+.IP "\(bu" 4
+Filter which rows display with built-in filters, user-defined filters, and
+quick-filters.
+.IP "\(bu" 4
+Sort the rows to put important data first or group together related rows.
+.IP "\(bu" 4
+Highlight rows with color.
+.IP "\(bu" 4
+Customize the alignment, width, and formatting of columns, and apply
+transformations to columns to extract parts of their values or format the values
+as you wish (for example, shortening large numbers to familiar units).
+.IP "\(bu" 4
+Design your own expressions to extract and combine data as you need.  This gives
+you unlimited flexibility.
+.PP
+All these and more are explained in the following sections.
+.SS "\s-1TABLES\s0"
+.IX Subsection "TABLES"
+A table is what you'd expect: a collection of columns.  It also has some other
+properties, such as a caption.  Filters, sorting rules, and colorization rules
+belong to tables and are covered in later sections.
+.PP
+Internally, table meta-data is defined in a data structure called \f(CW%tbl_meta\fR.
+This hash holds all built-in table definitions, which contain a lot of default
+instructions to innotop.  The meta-data includes the caption, a list of columns
+the user has customized, a list of columns, a list of visible columns, a list of
+filters, color rules, a sort-column list, sort direction, and some information
+about the table's data sources.  Most of this is customizable via the table
+editor (see \*(L"\s-1TABLE EDITOR\*(R"\s0).
+.PP
+You can choose which tables to show by pressing the '$' key.  See \*(L"\s-1MODES\*(R"\s0 and
+\&\*(L"\s-1TABLES\*(R"\s0.
+.PP
+The table life-cycle is as follows:
+.IP "\(bu" 4
+Each table begins with a data source, which is an array of hashes.  See below
+for details on data sources.
+.IP "\(bu" 4
+Each element of the data source becomes a row in the final table.
+.IP "\(bu" 4
+For each element in the data source, innotop extracts values from the source and
+creates a row.  This row is another hash, which later steps will refer to as
+\&\f(CW$set\fR.  The values innotop extracts are determined by the table's columns.  Each
+column has an extraction subroutine, compiled from an expression (see
+\&\*(L"\s-1EXPRESSIONS\*(R"\s0).  The resulting row is a hash whose keys are named the same as
+the column name.
+.IP "\(bu" 4
+innotop filters the rows, removing those that don't need to be displayed.  See
+\&\*(L"\s-1FILTERS\*(R"\s0.
+.IP "\(bu" 4
+innotop sorts the rows.  See \*(L"\s-1SORTING\*(R"\s0.
+.IP "\(bu" 4
+innotop groups the rows together, if specified.  See \*(L"\s-1GROUPING\*(R"\s0.
+.IP "\(bu" 4
+innotop colorizes the rows.  See \*(L"\s-1COLORS\*(R"\s0.
+.IP "\(bu" 4
+innotop transforms the column values in each row.  See \*(L"\s-1TRANSFORMATIONS\*(R"\s0.
+.IP "\(bu" 4
+innotop optionally pivots the rows (see \*(L"\s-1PIVOTING\*(R"\s0), then filters and sorts
+them.
+.IP "\(bu" 4
+innotop formats and justifies the rows as a table.  During this step, innotop
+applies further formatting to the column values, including alignment, maximum
+and minimum widths.  innotop also does final error checking to ensure there are
+no crashes due to undefined values.  innotop then adds a caption if specified,
+and the table is ready to print.
+.PP
+The lifecycle is slightly different if the table is pivoted, as noted above.  To
+clarify, if the table is pivoted, the process is extract, group, transform,
+pivot, filter, sort, create.  If it's not pivoted, the process is extract,
+filter, sort, group, color, transform, create.  This slightly convoluted process
+doesn't map all that well to \s-1SQL,\s0 but pivoting complicates things pretty
+thoroughly.  Roughly speaking, filtering and sorting happen as late as needed to
+effect the final result as you might expect, but as early as possible for
+efficiency.

+.SS "\s-1COLUMNS\s0"
+.IX Subsection "COLUMNS"
+Columns belong to tables.  You can choose a table's columns by pressing the '^'
+key, which starts the \*(L"\s-1TABLE EDITOR\*(R"\s0 and lets you choose and edit columns.
+Pressing 'e' from within the table editor lets you edit the column's properties:
+.IP "\(bu" 4
+hdr: a column header.  This appears in the first row of the table.
+.IP "\(bu" 4
+just: justification.  '\-' means left-justified and '' means right-justified,
+just as with printf formatting codes (not a coincidence).
+.IP "\(bu" 4
+dec: whether to further align the column on the decimal point.
+.IP "\(bu" 4
+num: whether the column is numeric.  This affects how values are sorted
+(lexically or numerically).
+.IP "\(bu" 4
+label: a small note about the column, which appears in dialogs that help the
+user choose columns.
+.IP "\(bu" 4
+src: an expression that innotop uses to extract the column's data from its
+source (see \*(L"\s-1DATA SOURCES\*(R"\s0).  See \*(L"\s-1EXPRESSIONS\*(R"\s0 for more on expressions.
+.IP "\(bu" 4
+minw: specifies a minimum display width.  This helps stabilize the display,
+which makes it easier to read if the data is changing frequently.
+.IP "\(bu" 4
+maxw: similar to minw.
+.IP "\(bu" 4
+trans: a list of column transformations.  See \*(L"\s-1TRANSFORMATIONS\*(R"\s0.
+.IP "\(bu" 4
+agg: an aggregate function.  See \*(L"\s-1GROUPING\*(R"\s0.  The default is \*(L"first\*(R".
+.IP "\(bu" 4
+aggonly: controls whether the column only shows when grouping is enabled on the
+table (see \*(L"\s-1GROUPING\*(R"\s0).  By default, this is disabled.  This means columns
+will always be shown by default, whether grouping is enabled or not.  If a
+column's aggonly is set true, the column will appear when you toggle grouping on
+the table.  Several columns are set this way, such as the count column on
+\&\*(L"processlist\*(R" and \*(L"innodb_transactions\*(R", so you don't see a count when the
+grouping isn't enabled, but you do when it is.
+.IP "\(bu" 4
+agghide: the reverse of aggonly.  The column is hidden when grouping is enabled.
+.SS "\s-1FILTERS\s0"
+.IX Subsection "FILTERS"
+Filters remove rows from the display.  They behave much like a \s-1WHERE\s0 clause in
+\&\s-1SQL. \s0 innotop has several built-in filters, which remove irrelevant information
+like inactive queries, but you can define your own as well.  innotop also lets
+you create quick-filters, which do not get saved to the configuration file, and
+are just an easy way to quickly view only some rows.
+.PP
+You can enable or disable a filter on any table.  Press the '%' key (mnemonic: %
+looks kind of like a line being filtered between two circles) and choose which
+table you want to filter, if asked.  You'll then see a list of possible filters
+and a list of filters currently enabled for that table.  Type the names of
+filters you want to apply and press Enter.
+.PP
+\fIUSER-DEFINED \s-1FILTERS\s0\fR
+.IX Subsection "USER-DEFINED FILTERS"
+.PP
+If you type a name that doesn't exist, innotop will prompt you to create the
+filter.  Filters are easy to create if you know Perl, and not hard if you don't.
+What you're doing is creating a subroutine that returns true if the row should
+be displayed.  The row is a hash reference passed to your subroutine as \f(CW$set\fR.
+.PP
+For example, imagine you want to filter the processlist table so you only see
+queries that have been running more than five minutes.  Type a new name for your
+filter, and when prompted for the subroutine body, press \s-1TAB\s0 to initiate your
+terminal's auto-completion.  You'll see the names of the columns in the
+\&\*(L"processlist\*(R" table (innotop generally tries to help you with auto-completion
+lists).  You want to filter on the 'time' column.  Type the text \*(L"$set\->{time} >
+300\*(R" to return true when the query is more than five minutes old.  That's all
+you need to do.
+.PP
+In other words, the code you're typing is surrounded by an implicit context,
+which looks like this:
+.PP
+.Vb 4
+\& sub filter {
+\&    my ( $set ) = @_;
+\&    # YOUR CODE HERE
+\& }
+.Ve
+.PP
+If your filter doesn't work, or if something else suddenly behaves differently,
+you might have made an error in your filter, and innotop is silently catching
+the error.  Try enabling \*(L"debug\*(R" to make innotop throw an error instead.
+.PP
+\fIQUICK-FILTERS\fR
+.IX Subsection "QUICK-FILTERS"
+.PP
+innotop's quick-filters are a shortcut to create a temporary filter that doesn't
+persist when you restart innotop.  To create a quick-filter, press the '/' key.
+innotop will prompt you for the column name and filter text.  Again, you can use
+auto-completion on column names.  The filter text can be just the text you want
+to \*(L"search for.\*(R"  For example, to filter the \*(L"processlist\*(R" table on queries
+that refer to the products table, type '/' and then 'info product'.  Internally,
+the filter is compiled into a subroutine like this:
+.PP
+.Vb 4
+\& sub filter {
+\&    my ( $set ) = @_;
+\&    $set\->{info} =~ m/product/;
+\& }
+.Ve
+.PP
+The filter text can actually be any Perl regular expression, but of course a
+literal string like 'product' works fine as a regular expression.
+.PP
+What if you want the filter to discard matching rows, rather than showing
+matching rows?  If you're familiar with Perl regular expressions, you might
+guess how to do this.  You have to use a zero-width negative lookahead
+assertion.  If you don't know what that means, don't worry.  Let's filter out
+all rows where the command is Gandalf.  Type the following:
+.PP
+.Vb 2
+\& 1. /
+\& 2. cmd ^(?!Gandalf)
+.Ve
+.PP
+Behind the scenes innotop compiles the quick-filter into a specially tagged
+filter that is otherwise like any other filter.  It just isn't saved to the
+configuration file.
+.PP
+To clear quick-filters, press the '\e' key and innotop will clear them all at
+once.
+.SS "\s-1SORTING\s0"
+.IX Subsection "SORTING"
+innotop has sensible built-in defaults to sort the most important rows to the
+top of the table.  Like anything else in innotop, you can customize how any
+table is sorted.
+.PP
+To start the sort dialog, start the \*(L"\s-1TABLE EDITOR\*(R"\s0 with the '^' key, choose a
+table if necessary, and press the 's' key.  You'll see a list of columns you can
+use in the sort expression and the current sort expression, if any.  Enter a
+list of columns by which you want to sort and press Enter.  If you want to
+reverse sort, prefix the column name with a minus sign.  For example, if you
+want to sort by column a ascending, then column b descending, type 'a \-b'.  You
+can also explicitly add a + in front of columns you want to sort ascending, but
+it's not required.
+.PP
+Some modes have keys mapped to open this dialog directly, and to quickly reverse
+sort direction.  Press '?' as usual to see which keys are mapped in any mode.
+.SS "\s-1GROUPING\s0"
+.IX Subsection "GROUPING"
+innotop can group, or aggregate, rows together (the terms are used
+interchangeably).  This is quite similar to an \s-1SQL GROUP BY\s0 clause.  You can
+specify to group on certain columns, or if you don't specify any, the entire set
+of rows is treated as one group.  This is quite like \s-1SQL\s0 so far, but unlike \s-1SQL,\s0
+you can also select un-grouped columns.  innotop actually aggregates every
+column.  If you don't explicitly specify a grouping function, the default is
+\&'first'.  This is basically a convenience so you don't have to specify an
+aggregate function for every column you want in the result.
+.PP
+You can quickly toggle grouping on a table with the '=' key, which toggles its
+aggregate property.  This property doesn't persist to the config file.
+.PP
+The columns by which the table is grouped are specified in its group_by
+property.  When you turn grouping on, innotop places the group_by columns at the
+far left of the table, even if they're not supposed to be visible.  The rest of
+the visible columns appear in order after them.
+.PP
+Two tables have default group_by lists and a count column built in:
+\&\*(L"processlist\*(R" and \*(L"innodb_transactions\*(R".  The grouping is by connection
+and status, so you can quickly see how many queries or transactions are in a
+given status on each server you're monitoring.  The time columns are aggregated
+as a sum; other columns are left at the default 'first' aggregation.
+.PP
+By default, the table shown in \*(L"S: Variables & Status\*(R" mode also uses
+grouping so you can monitor variables and status across many servers.  The
+default aggregation function in this mode is 'avg'.
+.PP
+Valid grouping functions are defined in the \f(CW%agg_funcs\fR hash.  They include
+.IP "first" 4
+.IX Item "first"
+Returns the first element in the group.
+.IP "count" 4
+.IX Item "count"
+Returns the number of elements in the group, including undefined elements, much
+like \s-1SQL\s0's \s-1COUNT\s0(*).
+.IP "avg" 4
+.IX Item "avg"
+Returns the average of defined elements in the group.
+.IP "sum" 4
+.IX Item "sum"
+Returns the sum of elements in the group.
+.PP
+Here's an example of grouping at work.  Suppose you have a very busy server with
+hundreds of open connections, and you want to see how many connections are in
+what status.  Using the built-in grouping rules, you can press 'Q' to enter
+\&\*(L"Q: Query List\*(R" mode.  Press '=' to toggle grouping (if necessary, select the
+\&\*(L"processlist\*(R" table when prompted).
+.PP
+Your display might now look like the following:
+.PP
+.Vb 1
+\& Query List (? for help) localhost, 32:33, 0.11 QPS, 1 thd, 5.0.38\-log
+\&
+\& CXN        Cmd        Cnt  ID      User   Host           Time   Query
+\& localhost  Query      49    12933  webusr localhost      19:38  SELECT * FROM
+\& localhost  Sending Da 23     2383  webusr localhost      12:43  SELECT col1,
+\& localhost  Sleep      120     140  webusr localhost    5:18:12
+\& localhost  Statistics 12    19213  webusr localhost      01:19  SELECT * FROM
+.Ve
+.PP
+That's actually quite a worrisome picture.  You've got a lot of idle connections
+(Sleep), and some connections executing queries (Query and Sending Data).
+That's okay, but you also have a lot in Statistics status, collectively spending
+over a minute.  That means the query optimizer is having a really hard time
+generating execution plans for your statements.  Something is wrong; it should
+normally take milliseconds to plan queries.  You might not have seen this pattern if you
+didn't look at your connections in aggregate.  (This is a made-up example, but
+it can happen in real life).
+.SS "\s-1PIVOTING\s0"
+.IX Subsection "PIVOTING"
+innotop can pivot a table for more compact display, similar to a Pivot Table in
+a spreadsheet (also known as a crosstab).  Pivoting a table makes columns into
+rows.  Assume you start with this table:
+.PP
+.Vb 4
+\& foo bar
+\& === ===
+\& 1   3
+\& 2   4
+.Ve
+.PP
+After pivoting, the table will look like this:
+.PP
+.Vb 4
+\& name set0 set1
+\& ==== ==== ====
+\& foo  1    2
+\& bar  3    4
+.Ve
+.PP
+To get reasonable results, you might need to group as well as pivoting.
+innotop currently does this for \*(L"S: Variables & Status\*(R" mode.
+.SS "\s-1COLORS\s0"
+.IX Subsection "COLORS"
+By default, innotop highlights rows with color so you can see at a glance which
+rows are more important.  You can customize the colorization rules and add your
+own to any table.  Open the table editor with the '^' key, choose a table if
+needed, and press 'o' to open the color editor dialog.
+.PP
+The color editor dialog displays the rules applied to the table, in the order
+they are evaluated.  Each row is evaluated against each rule to see if the rule
+matches the row; if it does, the row gets the specified color, and no further
+rules are evaluated.  The rules look like the following:
+.PP
+.Vb 9
+\& state  eq  Locked       black on_red
+\& cmd    eq  Sleep        white
+\& user   eq  system user  white
+\& cmd    eq  Connect      white
+\& cmd    eq  Binlog Dump  white
+\& time   >   600          red
+\& time   >   120          yellow
+\& time   >   60           green
+\& time   >   30           cyan
+.Ve
+.PP
+This is the default rule set for the \*(L"processlist\*(R" table.  In order of
+priority, these rules make locked queries black on a red background, \*(L"gray out\*(R"
+connections from replication and sleeping queries, and make queries turn from
+cyan to red as they run longer.
+.PP
+(For some reason, the \s-1ANSI\s0 color code \*(L"white\*(R" is actually a light gray.  Your
+terminal's display may vary; experiment to find colors you like).
+.PP
+You can use keystrokes to move the rules up and down, which re-orders their
+priority.  You can also delete rules and add new ones.  If you add a new rule,
+innotop prompts you for the column, an operator for the comparison, a value
+against which to compare the column, and a color to assign if the rule matches.
+There is auto-completion and prompting at each step.
+.PP
+The value in the third step needs to be correctly quoted.  innotop does not try
+to quote the value because it doesn't know whether it should treat the value as
+a string or a number.  If you want to compare the column against a string, as
+for example in the first rule above, you should enter 'Locked' surrounded by
+quotes.  If you get an error message about a bareword, you probably should have
+quoted something.
+.SS "\s-1EXPRESSIONS\s0"
+.IX Subsection "EXPRESSIONS"
+Expressions are at the core of how innotop works, and are what enables you to
+extend innotop as you wish.  Recall the table lifecycle explained in
+\&\*(L"\s-1TABLES\*(R"\s0.  Expressions are used in the earliest step, where it extracts
+values from a data source to form rows.
+.PP
+It does this by calling a subroutine for each column, passing it the source data
+set, a set of current values, and a set of previous values.  These are all
+needed so the subroutine can calculate things like the difference between this
+tick and the previous tick.
+.PP
+The subroutines that extract the data from the set are compiled from
+expressions.  This gives significantly more power than just naming the values to
+fill the columns, because it allows the column's value to be calculated from
+whatever data is necessary, but avoids the need to write complicated and lengthy
+Perl code.
+.PP
+innotop begins with a string of text that can look as simple as a value's name
+or as complicated as a full-fledged Perl expression.  It looks at each
+\&'bareword' token in the string and decides whether it's supposed to be a key
+into the \f(CW$set\fR hash.  A bareword is an unquoted value that isn't already
+surrounded by code-ish things like dollar signs or curly brackets.  If innotop
+decides that the bareword isn't a function or other valid Perl code, it converts
+it into a hash access.  After the whole string is processed, innotop compiles a
+subroutine, like this:
+.PP
+.Vb 5
+\& sub compute_column_value {
+\&    my ( $set, $cur, $pre ) = @_;
+\&    my $val = # EXPANDED STRING GOES HERE
+\&    return $val;
+\& }
+.Ve
+.PP
+Here's a concrete example, taken from the header table \*(L"q_header\*(R" in \*(L"Q:
+Query List\*(R" mode.  This expression calculates the qps, or Queries Per Second,
+column's values, from the values returned by \s-1SHOW STATUS:\s0
+.PP
+.Vb 1
+\& Questions/Uptime_hires
+.Ve
+.PP
+innotop decides both words are barewords, and transforms this expression into
+the following Perl code:
+.PP
+.Vb 1
+\& $set\->{Questions}/$set\->{Uptime_hires}
+.Ve
+.PP
+When surrounded by the rest of the subroutine's code, this is executable Perl
+that calculates a high-resolution queries-per-second value.
+.PP
+The arguments to the subroutine are named \f(CW$set\fR, \f(CW$cur\fR, and \f(CW$pre\fR.  In most cases,
+\&\f(CW$set\fR and \f(CW$cur\fR will be the same values.  However, if \*(L"status_inc\*(R" is set, \f(CW$cur\fR
+will not be the same as \f(CW$set\fR, because \f(CW$set\fR will already contain values that are
+the incremental difference between \f(CW$cur\fR and \f(CW$pre\fR.
+.PP
+Every column in innotop is computed by subroutines compiled in the same fashion.
+There is no difference between innotop's built-in columns and user-defined
+columns.  This keeps things consistent and predictable.
+.SS "\s-1TRANSFORMATIONS\s0"
+.IX Subsection "TRANSFORMATIONS"
+Transformations change how a value is rendered.  For example, they can take a
+number of seconds and display it in H:M:S format.  The following transformations
+are defined:
+.IP "commify" 4
+.IX Item "commify"
+Adds commas to large numbers every three decimal places.
+.IP "distill" 4
+.IX Item "distill"
+Distills \s-1SQL\s0 into verb-noun-noun format for quick comprehension.
+.IP "dulint_to_int" 4
+.IX Item "dulint_to_int"
+Accepts two unsigned integers and converts them into a single longlong.  This is
+useful for certain operations with InnoDB, which uses two integers as
+transaction identifiers, for example.
+.IP "fuzzy_time" 4
+.IX Item "fuzzy_time"
+Converts a number of seconds into a friendly, readable value like \*(L"1h35m\*(R".
+.IP "no_ctrl_char" 4
+.IX Item "no_ctrl_char"
+Removes quoted control characters from the value.  This is affected by the
+\&\*(L"charset\*(R" configuration variable.
+.Sp
+This transformation only operates within quoted strings, for example, values to
+a \s-1SET\s0 clause in an \s-1UPDATE\s0 statement.  It will not alter the \s-1UPDATE\s0 statement,
+but will collapse the quoted string to [\s-1BINARY\s0] or [\s-1TEXT\s0], depending on the
+charset.
+.IP "percent" 4
+.IX Item "percent"
+Converts a number to a percentage by multiplying it by two, formatting it with

+.Ve
+.PP
+The first line shows which table you're editing, and reminds you again to press
+\&'?' for a list of key mappings.  The rest is a tabular representation of the
+table's columns, because that's likely what you're trying to edit.  However, you
+can edit more than just the table's columns; this screen can start the filter
+editor, color rule editor, and more.
+.PP
+Each row in the display shows a single column in the table you're editing, along
+with a couple of its properties such as its header and source expression (see
+\&\*(L"\s-1EXPRESSIONS\*(R"\s0).
+.PP
+The key mappings are Vim-style, as in many other places.  Pressing 'j' and 'k'
+moves the highlight up or down.  You can then (d)elete or (e)dit the highlighted
+column.  You can also (a)dd a column to the table.  This actually just activates
+one of the columns already defined for the table; it prompts you to choose from
+among the columns available but not currently displayed.  Finally, you can
+re-order the columns with the '+' and '\-' keys.
+.PP
+You can do more than just edit the columns with the table editor, you can also
+edit other properties, such as the table's sort expression and group-by
+expression.  Press '?' to see the full list, of course.
+.PP
+If you want to really customize and create your own column, as opposed to just
+activating a built-in one that's not currently displayed, press the (n)ew key,
+and innotop will prompt you for the information it needs:
+.IP "\(bu" 4
+The column name: this needs to be a word without any funny characters, e.g. just
+letters, numbers and underscores.
+.IP "\(bu" 4
+The column header: this is the label that appears at the top of the column, in
+the table header.  This can have spaces and funny characters, but be careful not
+to make it too wide and waste space on-screen.
+.IP "\(bu" 4
+The column's data source: this is an expression that determines what data from
+the source (see \*(L"\s-1TABLES\*(R"\s0) innotop will put into the column.  This can just be
+the name of an item in the source, or it can be a more complex expression, as
+described in \*(L"\s-1EXPRESSIONS\*(R"\s0.
+.PP
+Once you've entered the required data, your table has a new column.  There is no
+difference between this column and the built-in ones; it can have all the same
+properties and behaviors.  innotop will write the column's definition to the
+configuration file, so it will persist across sessions.
+.PP
+Here's an example: suppose you want to track how many times your slaves have
+retried transactions.  According to the MySQL manual, the
+Slave_retried_transactions status variable gives you that data: \*(L"The total
+number of times since startup that the replication slave \s-1SQL\s0 thread has retried
+transactions. This variable was added in version 5.0.4.\*(R"  This is appropriate to
+add to the \*(L"slave_sql_status\*(R" table.
+.PP
+To add the column, switch to the replication-monitoring mode with the 'M' key,
+and press the '^' key to start the table editor.  When prompted, choose
+slave_sql_status as the table, then press 'n' to create the column.  Type
+\&'retries' as the column name, 'Retries' as the column header, and
+\&'Slave_retried_transactions' as the source.  Now the column is created, and you
+see the table editor screen again.  Press 'q' to exit the table editor, and
+you'll see your column at the end of the table.
+.SH "VARIABLE SETS"
+.IX Header "VARIABLE SETS"
+Variable sets are used in \*(L"S: Variables & Status\*(R" mode to define more easily
+what variables you want to monitor.  Behind the scenes they are compiled to a
+list of expressions, and then into a column list so they can be treated just
+like columns in any other table, in terms of data extraction and
+transformations.  However, you're protected from the tedious details by a syntax
+that ought to feel very natural to you: a \s-1SQL SELECT\s0 list.
+.PP
+The data source for variable sets, and indeed the entire S mode, is the
+combination of \s-1SHOW STATUS, SHOW VARIABLES,\s0 and \s-1SHOW INNODB STATUS. \s0 Imagine
+that you had a huge table with one column per variable returned from those
+statements.  That's the data source for variable sets.  You can now query this
+data source just like you'd expect.  For example:
+.PP
+.Vb 1
+\& Questions, Uptime, Questions/Uptime as QPS
+.Ve
+.PP
+Behind the scenes innotop will split that variable set into three expressions,
+compile them and turn them into a table definition, then extract as usual.  This
+becomes a \*(L"variable set,\*(R" or a \*(L"list of variables you want to monitor.\*(R"
+.PP
+innotop lets you name and save your variable sets, and writes them to the
+configuration file.  You can choose which variable set you want to see with the
+\&'c' key, or activate the next and previous sets with the '>' and '<' keys.
+There are many built-in variable sets as well, which should give you a good
+start for creating your own.  Press 'e' to edit the current variable set, or
+just to see how it's defined.  To create a new one, just press 'c' and type its
+name.
+.PP
+You may want to use some of the functions listed in \*(L"\s-1TRANSFORMATIONS\*(R"\s0 to help
+format the results.  In particular, \*(L"set_precision\*(R" is often useful to limit
+the number of digits you see.  Extending the above example, here's how:
+.PP
+.Vb 1
+\& Questions, Uptime, set_precision(Questions/Uptime) as QPS
+.Ve
+.PP
+Actually, this still needs a little more work.  If your \*(L"interval\*(R" is less
+than one second, you might be dividing by zero because Uptime is incremental in
+this mode by default.  Instead, use Uptime_hires:
+.PP
+.Vb 1
+\& Questions, Uptime, set_precision(Questions/Uptime_hires) as QPS
+.Ve
+.PP
+This example is simple, but it shows how easy it is to choose which variables
+you want to monitor.
+.SH "PLUGINS"
+.IX Header "PLUGINS"
+innotop has a simple but powerful plugin mechanism by which you can extend
+or modify its existing functionality, and add new functionality.  innotop's
+plugin functionality is event-based: plugins register themselves to be called
+when events happen.  They then have a chance to influence the event.
+.PP
+An innotop plugin is a Perl module (.pm) file placed in innotop's \*(L"plugin_dir\*(R"
+directory.  On \s-1UNIX\s0 systems, you can place a symbolic link to the module instead
+of putting the actual file there.  innotop automatically discovers files named \f(CW\*(C`*.pm\*(C'\fR.  If
+there is a corresponding entry in the \*(L"plugins\*(R" configuration file section,
+innotop loads and activates the plugin.
+.PP
+The module must conform to innotop's plugin interface.  Additionally, the source
+code of the module must be written in such a way that innotop can inspect the
+file and determine the package name and description.
+.SS "Package Source Convention"
+.IX Subsection "Package Source Convention"
+innotop inspects the plugin module's source to determine the Perl package name.
+It looks for a line of the form \*(L"package Foo;\*(R" and if found, considers the
+plugin's package name to be Foo.  Of course the package name can be a valid Perl
+package name such as Foo::Bar, with double colons (::) and so on.
+.PP
+It also looks for a description in the source code, to make the plugin editor
+more human-friendly.  The description is a comment line of the form \*(L"#
+description: Foo\*(R", where \*(L"Foo\*(R" is the text innotop will consider to be the
+plugin's description.
+.SS "Plugin Interface"
+.IX Subsection "Plugin Interface"
+The innotop plugin interface is quite simple: innotop expects the plugin to be
+an object-oriented module it can call certain methods on.  The methods are
+.IP "new(%variables)" 4
+.IX Item "new(%variables)"
+This is the plugin's constructor.  It is passed a hash of innotop's variables,
+which it can manipulate (see \*(L"Plugin Variables\*(R").  It must return a reference
+to the newly created plugin object.
+.Sp
+At construction time, innotop has only loaded the general configuration and
+created the default built-in variables with their default contents (which is
+quite a lot).  Therefore, the state of the program is exactly as in the innotop
+source code, plus the configuration variables from the \*(L"general\*(R" section in
+the config file.
+.Sp
+If your plugin manipulates the variables, it is changing global data, which is
+shared by innotop and all plugins.  Plugins are loaded in the order they're
+listed in the config file.  Your plugin may load before or after another plugin,
+so there is a potential for conflict or interaction between plugins if they
+modify data other plugins use or modify.
+.IP "\fIregister_for_events()\fR" 4
+.IX Item "register_for_events()"
+This method must return a list of events in which the plugin is interested, if
+any.  See \*(L"Plugin Events\*(R" for the defined events.  If the plugin returns an
+event that's not defined, the event is ignored.
+.IP "event handlers" 4
+.IX Item "event handlers"
+The plugin must implement a method named the same as each event for which it has
+registered.  In other words, if the plugin returns qw(foo bar) from
+\&\fIregister_for_events()\fR, it must have \fIfoo()\fR and \fIbar()\fR methods.  These methods are
+callbacks for the events.  See \*(L"Plugin Events\*(R" for more details about each
+event.
+.SS "Plugin Variables"
+.IX Subsection "Plugin Variables"
+The plugin's constructor is passed a hash of innotop's variables, which it can
+manipulate.  It is probably a good idea if the plugin object saves a copy of it
+for later use.  The variables are defined in the innotop variable
+\&\f(CW%pluggable_vars\fR, and are as follows:
+.IP "action_for" 4
+.IX Item "action_for"
+A hashref of key mappings.  These are innotop's global hot-keys.
+.IP "agg_funcs" 4
+.IX Item "agg_funcs"

+objects.

+A hashref of variable sets.  See \*(L"\s-1VARIABLE SETS\*(R"\s0.
+.SS "Plugin Events"
+.IX Subsection "Plugin Events"
+Each event is defined somewhere in the innotop source code.  When innotop runs
+that code, it executes the callback function for each plugin that expressed its
+interest in the event.  innotop passes some data for each event.  The events are
+defined in the \f(CW%event_listener_for\fR variable, and are as follows:
+.ie n .IP "extract_values($set, $cur, $pre, $tbl)" 4
+.el .IP "extract_values($set, \f(CW$cur\fR, \f(CW$pre\fR, \f(CW$tbl\fR)" 4
+.IX Item "extract_values($set, $cur, $pre, $tbl)"
+This event occurs inside the function that extracts values from a data source.
+The arguments are the set of values, the current values, the previous values,
+and the table name.
+.IP "set_to_tbl" 4
+.IX Item "set_to_tbl"
+Events are defined at many places in this subroutine, which is responsible for
+turning an arrayref of hashrefs into an arrayref of lines that can be printed to
+the screen.  The events all pass the same data: an arrayref of rows and the name
+of the table being created.  The events are set_to_tbl_pre_filter,
+set_to_tbl_pre_sort,set_to_tbl_pre_group, set_to_tbl_pre_colorize,
+set_to_tbl_pre_transform, set_to_tbl_pre_pivot, set_to_tbl_pre_create,
+set_to_tbl_post_create.
+.IP "draw_screen($lines)" 4
+.IX Item "draw_screen($lines)"
+This event occurs inside the subroutine that prints the lines to the screen.
+\&\f(CW$lines\fR is an arrayref of strings.
+.SS "Simple Plugin Example"
+.IX Subsection "Simple Plugin Example"
+The easiest way to explain the plugin functionality is probably with a simple
+example.  The following module adds a column to the beginning of every table and
+sets its value to 1.  (If you copy and paste this example code, be sure to remove
+the first space from each line; lines such as '# description' must not start with

+.IX Header "DATA SOURCES"
+Each time innotop extracts values to create a table (see \*(L"\s-1EXPRESSIONS\*(R"\s0 and
+\&\*(L"\s-1TABLES\*(R"\s0), it does so from a particular data source.  Largely because of the
+complex data extracted from \s-1SHOW INNODB STATUS,\s0 this is slightly messy.  \s-1SHOW
+INNODB STATUS\s0 contains a mixture of single values and repeated values that form
+nested data sets.
+.PP
+Whenever innotop fetches data from MySQL, it adds two extra bits to each set:
+cxn and Uptime_hires.  cxn is the name of the connection from which the data
+came.  Uptime_hires is a high-resolution version of the server's Uptime status

+.SH "SYSTEM REQUIREMENTS"
+.IX Header "SYSTEM REQUIREMENTS"
+You need Perl to run innotop, of course.  You also need a few Perl modules: \s-1DBI,\s0
+DBD::MariaDB,  Term::ReadKey, and Time::HiRes.  These should be included with most
+Perl distributions, but in case they are not, I recommend using versions
+distributed with your operating system or Perl distribution, not from \s-1CPAN.\s0
+Term::ReadKey in particular has been known to cause problems if installed from
+\&\s-1CPAN.\s0
+.PP
+If you have Term::ANSIColor, innotop will use it to format headers more readably
+and compactly.  (Under Microsoft Windows, you also need Win32::Console::ANSI for
+terminal formatting codes to be honored).  If you install Term::ReadLine,
+preferably Term::ReadLine::Gnu, you'll get nice auto-completion support.
+.PP
+I run innotop on Gentoo GNU/Linux, Debian and Ubuntu, and I've had feedback from
+people successfully running it on Red Hat, CentOS, Solaris, and Mac \s-1OSX.  I\s0
+don't see any reason why it won't work on other UNIX-ish operating systems, but
+I don't know for sure.  It also runs on Windows under ActivePerl without
+problem.
+.PP
+innotop has been used on MySQL versions 3.23.58, 4.0.27, 4.1.0, 4.1.22, 5.0.26,
+5.1.15, and 5.2.3.  If it doesn't run correctly for you, that is a bug that
+should be reported.
+.SH "FILES"
+.IX Header "FILES"
+\&\f(CW$HOMEDIR\fR/.innotop and/or /etc/innotop are used to store
+configuration information.  Files include the configuration file innotop.conf,
+the core_dump file which contains verbose error messages if \*(L"debug\*(R" is
+enabled, and the plugins/ subdirectory.
+.SH "GLOSSARY OF TERMS"

+mariadb-report v4.0 Oct 23 2015
+mariadb-report makes an easy-to-read report of important MySQL/MariaDB status values.
+
+Command line options (abbreviations work):
+   --user USER       Connect to MySQL as USER
+   --password PASS   Use PASS or prompt for MySQL user's password
+   --host ADDRESS    Connect to MySQL at ADDRESS
+   --port PORT       Connect to MySQL at PORT
+   --socket SOCKET   Connect to MySQL at SOCKET
+   --no-mycnf        Don't read ~/.my.cnf
+   --infile FILE     Read status values from FILE instead of MySQL
+   --outfile FILE    Write report to FILE
+   --email ADDRESS   Email report to ADDRESS (doesn't work on Windows)
+   --flush-status    Issue FLUSH STATUS; after getting current values
+   --relative X      Generate relative reports. If X is an integer,
+                     reports are live from the MySQL server X seconds apart.
+                     If X is a list of infiles (file1 file2 etc.),
+                     reports are generated from the infiles in the order
+                     that they are given.
+   --report-count N  Collect N number of live relative reports (default 1)
+   --detach          Fork and detach from terminal (run in background)
+   --help            Prints this
+   --debug           Print debugging information

+.SH "NAME"
+.LP 
+mysqlreport \- Makes a friendly report of important MySQL status values
+.SH "SYNTAX"
+.LP 
+mysqlreport [\fIoptions\fP]
+.SH "DESCRIPTION"
+.LP 
+mysqlreport makes a friendly report of important MySQL status values. Actually,
+it makes a friendly report of nearly every status value from SHOW STATUS.
+Unlike SHOW STATUS which simply dumps over 100 values to screen in one long
+list, mysqlreport interprets and formats the values and presents the basic
+values and many more inferred values in a human\-readable format. Numerous
+example reports are available at the mysqlreport web page at
+http://hackmysql.com/mysqlreport.
+
+The benefit of mysqlreport is that it allows you to very quickly see a wide
+array of performance indicators for your MySQL server which would otherwise
+need to be calculated by hand from all the various SHOW STATUS values. For
+example, the Index Read Ratio is an important value but it's not present in
+SHOW STATUS; it's an inferred value (the ratio of Key_reads to
+Key_read_requests).
+
+This documentation outlines all the command line options in mysqlreport, most
+of which control which reports are printed. This document does not address
+how to interpret these reports; that topic is covered in the document Guide
+To Understanding mysqlreport at http://hackmysql.com/mysqlreportguide.
+
+.SH "OPTIONS"
+Technically, command line options are in the form \-\-option, but \-option works
+too. All options can be abbreviated if the abbreviation is unique. For example,
+option \-\-host can be abbreviated \-\-ho but not \-\-h because \-\-h is ambiguous: it
+could mean \-\-host or \-\-help.
+
+.LP 
+
+.TP 
+\fB\-\-help\fR
+Output help information and exit.
+
+.TP 
+\fB\-\-user USER\fR
+
+.TP 
+\fB\-\-password\fR
+As of version 2.3 \-\-password can take the password on the
+command line like "\-\-password FOO". Using \-\-password
+alone without giving a password on the command line
+causes mysqlreport to prompt for a password.
+
+.TP 
+\fB\-\-host ADDRESS\fR
+
+.TP 
+\fB\-\-port PORT\fR
+
+.TP
+\fB\-\-socket SOCKET\fR
+
+.TP 
+\fB\-\-no\-mycnf\fR
+\-\-no\-mycnf makes mysqlreport not read ~/.my.cnf which it does by default
+otherwise. \-\-user and \-\-password always override values from ~/.my.cnf.
+
+.TP 
+\fB\-\-dtq\fR
+Print Distribution of Total Queries (DTQ) report (under
+Total in Questions report). Queries (or Questions) can
+be divided into four main areas: DMS (see \-\-dms below),
+Com_ (see \-\-com below), COM_QUIT (see COM_QUIT and
+Questions at http://hackmysql.com/com_quit), and
+Unknown. \-\-dtq lists the number of queries in each of
+these areas in descending order.
+
+.TP 
+\fB\-\-dms\fR
+Print Data Manipulation Statements (DMS) report (under
+DMS in Questions report). DMS are those from the MySQL
+manual section 13.2. Data Manipulation Statements.
+(Currently, mysqlreport considers only SELECT, INSERT,
+REPLACE, UPDATE, and DELETE.) Each DMS is listed in
+descending order by count.
+
+.TP 
+\fB\-\-com N\fR
+Print top N number of non\-DMS Com_ status values in
+descending order (after DMS in Questions report). If N
+is not given, default is 3. Such non\-DMS Com_ values
+include Com_change_db, Com_show_tables, Com_rollback,
+etc.
+
+.TP 
+\fB\-\-sas\fR
+Print report for Select_ and Sort_ status values (after
+Questions report). See MySQL Select and Sort Status
+Variables at http://hackmysql.com/selectandsort.
+
+.TP
+\fB\-\-tab\fR
+Print Threads, Aborted, and Bytes status reports (after
+Created temp report). As of mysqlreport v2.3 the
+Threads report reports on all Threads_ status values.
+
+.TP
+\fB\-\-qcache\fR
+Print Query Cache report.
+.TP
+\fB\-\-all\fR
+Equivalent to "\-\-dtq \-\-dms \-\-com 3 \-\-sas \-\-qcache".
+(Notice \-\-tab is not invoked by \-\-all.)
+
+.TP
+\fB\-\-infile FILE\fR
+Instead of getting SHOW STATUS values from MySQL, read
+values from FILE. FILE is often a copy of the output of
+SHOW STATUS including formatting characters (|, +, \-).
+mysqlreport expects FILE to have the format
+" value number " where value is only alpha and
+underscore characters (A\-Z and _) and number is a
+positive integer. Anything before, between, or after
+value and number is ignored. mysqlreport also needs
+the following MySQL server variables: version,
+table_cache, max_connections, key_buffer_size,
+query_cache_size. These values can be specified in
+INFILE in the format "name = value" where name is one
+of the aforementioned server variables and value is a
+positive integer with or without a trailing M and
+possible periods (for version). For example, to specify
+an 18M key_buffer_size: key_buffer_size = 18M. Or, a
+256 table_cache: table_cache = 256. The M implies
+Megabytes not million, so 18M means 18,874,368 not
+18,000,000. If these server variables are not specified
+the following defaults are used (respectively) which
+may cause strange values to be reported: 0.0.0, 64,
+100, 8M, 0.
+
+.TP
+\fB\-\-outfile FILE\fR  
+After printing the report to screen, print the report
+to FILE too. Internally, mysqlreport always writes the
+report to a temp file first: /tmp/mysqlreport.PID on
+*nix, c:\mysqlreport.PID on Windows (PID is the
+script's process ID). Then it prints the temp file to
+screen. Then if \-\-outfile is specified, the temp file
+is copied to OUTFILE. After \-\-email (below), the temp
+file is deleted.
+
+.TP
+\fB\-\-email ADDRESS\fR
+After printing the report to screen, email the report
+to ADDRESS. This option requires sendmail in
+/usr/sbin/, therefore it does not work on Windows.
+/usr/sbin/sendmail can be a sym link to qmail, for
+example, or any MTA that emulates sendmail's \-t
+command line option and operation. The FROM: field is
+"mysqlreport", SUBJECT: is "MySQL status report".
+
+.TP
+\fB\-\-flush\-status\fR
+Execute a "FLUSH STATUS;" after generating the reports.
+If you do not have permissions in MySQL to do this an
+error from DBD::MariaDB::st will be printed after the
+reports.

+ Also, MySQL carries the "FOSS License Exception" specified in README
+ .
+ Quoting from README:
+ .
+ MySQL FOSS License Exception We want free and open source
+ software applications under certain licenses to be able to use
+ specified GPL-licensed MySQL client libraries despite the fact
+ that not all such FOSS licenses are compatible with version
+ 2 of the GNU General Public License.  Therefore there are
+ special exceptions to the terms and conditions of the GPLv2
+ as applied to these client libraries, which are identified
+ and described in more detail in the FOSS License Exception at
+ <http://www.mysql.com/about/legal/licensing/foss-exception.html>.
+ .
+ The text of the Above URL is quoted below, as of Aug 17, 2011.

+ > Oracle's MySQL Client Libraries (also referred to as "MySQL Drivers"
+ > or "MySQL Connectors") with their FOSS applications. MySQL Client
+ > Libraries are typically licensed pursuant to version 2 of the General
+ > Public License ("GPL"), but this exception permits distribution of

+License: Artistic
+ The "Artistic License"
+ .
+ Preamble
+ .
+ The intent of this document is to state the conditions under which a
+ Package may be copied, such that the Copyright Holder maintains some
+ semblance of artistic control over the development of the package,
+ while giving the users of the package the right to use and distribute
+ the Package in a more-or-less customary fashion, plus the right to make
+ reasonable modifications.
+ .
+ Definitions:
+ .
+ "Package" refers to the collection of files distributed by the
+ Copyright Holder, and derivatives of that collection of files
+ created through textual modification.
+ .
+ "Standard Version" refers to such a Package if it has not been
+ modified, or has been modified in accordance with the wishes
+ of the Copyright Holder as specified below.
+ .
+ "Copyright Holder" is whoever is named in the copyright or
+ copyrights for the package.
+ .
+ "You" is you, if you're thinking about copying or distributing
+ this Package.
+ .
+ "Reasonable copying fee" is whatever you can justify on the
+ basis of media cost, duplication charges, time of people involved,
+ and so on.  (You will not be required to justify it to the
+ Copyright Holder, but only to the computing community at large
+ as a market that must bear the fee.)
+ .
+ "Freely Available" means that no fee is charged for the item
+ itself, though there may be fees involved in handling the item.
+ It also means that recipients of the item may redistribute it
+ under the same conditions they received it.
+ .
+ 1. You may make and give away verbatim copies of the source form of the
+ Standard Version of this Package without restriction, provided that you
+ duplicate all of the original copyright notices and associated disclaimers.
+ .
+ 2. You may apply bug fixes, portability fixes and other modifications
+ derived from the Public Domain or from the Copyright Holder.  A Package
+ modified in such a way shall still be considered the Standard Version.
+ .
+ 3. You may otherwise modify your copy of this Package in any way, provided
+ that you insert a prominent notice in each changed file stating how and
+ when you changed that file, and provided that you do at least ONE of the
+ following:
+ .
+     a) place your modifications in the Public Domain or otherwise make them
+     Freely Available, such as by posting said modifications to Usenet or
+     an equivalent medium, or placing the modifications on a major archive
+     site such as uunet.uu.net, or by allowing the Copyright Holder to include
+     your modifications in the Standard Version of the Package.
+ .
+     b) use the modified Package only within your corporation or organization.
+ .
+     c) rename any non-standard executables so the names do not conflict
+     with standard executables, which must also be provided, and provide
+     a separate manual page for each non-standard executable that clearly
+     documents how it differs from the Standard Version.
+ .
+     d) make other distribution arrangements with the Copyright Holder.
+ .
+ 4. You may distribute the programs of this Package in object code or
+ executable form, provided that you do at least ONE of the following:
+ .
+     a) distribute a Standard Version of the executables and library files,
+     together with instructions (in the manual page or equivalent) on where
+     to get the Standard Version.
+ .
+     b) accompany the distribution with the machine-readable source of
+     the Package with your modifications.
+ .
+     c) give non-standard executables non-standard names, and clearly
+     document the differences in manual pages (or equivalent), together
+     with instructions on where to get the Standard Version.
+ .
+     d) make other distribution arrangements with the Copyright Holder.
+ .
+ 5. You may charge a reasonable copying fee for any distribution of this
+ Package.  You may charge any fee you choose for support of this
+ Package.  You may not charge a fee for this Package itself.  However,
+ you may distribute this Package in aggregate with other (possibly
+ commercial) programs as part of a larger (possibly commercial) software
+ distribution provided that you do not advertise this Package as a
+ product of your own.  You may embed this Package's interpreter within
+ an executable of yours (by linking); this shall be construed as a mere
+ form of aggregation, provided that the complete Standard Version of the
+ interpreter is so embedded.
+ .
+ 6. The scripts and library files supplied as input to or produced as
+ output from the programs of this Package do not automatically fall
+ under the copyright of this Package, but belong to whoever generated
+ them, and may be sold commercially, and may be aggregated with this
+ Package.  If such scripts or library files are aggregated with this
+ Package via the so-called "undump" or "unexec" methods of producing a
+ binary executable image, then distribution of such an image shall
+ neither be construed as a distribution of this Package nor shall it
+ fall under the restrictions of Paragraphs 3 and 4, provided that you do
+ not represent such an executable image as a Standard Version of this
+ Package.
+ .
+ 7. C subroutines (or comparably compiled subroutines in other
+ languages) supplied by you and linked into this Package in order to
+ emulate subroutines and variables of the language defined by this
+ Package shall not be considered part of this Package, but are the
+ equivalent of input as in Paragraph 6, provided these subroutines do
+ not change the language in any way that would cause it to fail the
+ regression tests for the language.
+ .
+ 8. Aggregation of this Package with a commercial distribution is always
+ permitted provided that the use of this Package is embedded; that is,
+ when no overt attempt is made to make this Package's interfaces visible
+ to the end user of the commercial distribution.  Such use shall not be
+ construed as a distribution of this Package.
+ .
+ 9. The name of the Copyright Holder may not be used to endorse or promote
+ products derived from this software without specific prior written permission.
+ .

+The libmariadb3.symbols files is used to track the libmariadb3 ABI.
+
+If a symbol is removed or changed, the Debian build will fail unless the same change has also explicitly been made in the libmariadb3.symbols file.
+
+If a symbol is added, the Debian build will issue a warning like:

+
+When this happens, please add the symbol to the libmariadb3.symbols file.
+Unlike the automatic diff above, don't use the server version for the symbols.
+
+Instead use the client library version, which can be viewed with:
+
+  $ grep 'SET(CPACK_PACKAGE_VERSION_' libmariadb/CMakeLists.txt 
+  SET(CPACK_PACKAGE_VERSION_MAJOR 3)
+  SET(CPACK_PACKAGE_VERSION_MINOR 1)
+  SET(CPACK_PACKAGE_VERSION_PATCH 7)
+
+In this example, the line to add would be:
+
+  mariadb_get_infov@libmariadb_3 3.1.7
+
+
+Remember to not break the ABI in a stable release!

+mariadb (1:10.11.2-1) unstable; urgency=medium
+
+  MariaDB 10.11.2 was released on February 16th 2023 by the MariaDB Foundation
+  (https://mariadb.org/mariadb-10-11-2-ga-now-available/). This is the first
+  release in the 10.11 series to be announced GA (general availability). The
+  10.11 series has long-term support with commitment from the MariaDB Foundation
+  (https://mariadb.org/about/#maintenance-policy) to publish maintenance
+  versions with fixes to software defects and security vulnerabilities until
+  February 2028.
+
+  The previous major releases (10.7, 10.8, 10.9, 10.10) were not long-terms
+  supported versions and thus not imported to Debian. To learn what is new in
+  10.11 it is recommended to read all the release notes:
+
+  * https://mariadb.com/kb/en/changes-improvements-in-mariadb-1011/
+  * https://mariadb.com/kb/en/changes-improvements-in-mariadb-1010/
+  * https://mariadb.com/kb/en/changes-improvements-in-mariadb-109/
+  * https://mariadb.com/kb/en/changes-improvements-in-mariadb-108/
+  * https://mariadb.com/kb/en/changes-improvements-in-mariadb-107/
+
+  Noteable new features:
+  - New datatypes UUID and INET4
+  - New functions SFORMAT (text formatting), NATURAL_SORT_KEY, RANDOM_BYTES and
+    several related to JSON
+  - New keyword AUTO in system versioned tables for partitioning
+    (https://mariadb.com/kb/en/system-versioned-tables/#automatically-creating-partitions)
+  - Unicode Collation Algorithm (UCA) upgrade to 14.0.0
+  - New privileges 'READ ONLY ADMIN' and 'GRANT TO PUBLIC'
+    (https://mariadb.org/grant-to-public-in-mariadb/)
+  - password_reuse_check plugin (part of mariadb-server package)
+  - Hashicorp Key Management Plugin for implementing encryption using keys
+    stored in the Hashicorp Vault KMS (mariadb-plugin-hashicorp-key-management
+    package)
+
+  Important packaging change: Compression libraries have been split into
+  separate packages named mariadb-provider-plugin-(bzip2/lz4/lzma/lzo/snappy).
+  If a non-zlib compression algorithm was used in InnoDB or Mroonga before
+  upgrading to 10.11, those tables will be unreadable until the appropriate
+  compression library is installed.
+
+  Things to consider when upgrading from 10.6 to 10.11 are listed on the page
+  https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/.
+
+  New server variables in 10.11 (compared to 10.6):
+  - binlog-alter-two-phase: When set, split ALTER at binary logging into 2
+    statements: START ALTER and COMMIT/ROLLBACK ALTER. Defaults to 'FALSE'.
+  - innodb-log-file-buffering: Whether the file system cache for ib_logfile0 is
+    enabled
+  - optimizer-extra-pruning-depth: If the optimizer needs to enumerate join
+    prefix of this size or larger, then it will try aggressively prune away the
+    search space.
+  - log-slow-min-examined-row-limit: Don't write queries to slow log that
+    examine fewer rows than that
+  - log-slow-query: Log slow queries to a table or log file. Defaults logging to
+    a file 'hostname'-slow.log or a table mysql.slow_log if --log-output=TABLE
+    is used. Must be enabled to activate other slow log options.
+  - log-slow-query-file: Log slow queries to given log file. Defaults logging to
+    'hostname'-slow.log. Must be enabled to activate other slow log options
+  - log-slow-query-time: Log all queries that have taken more than
+    log_slow_query_time seconds to execute to the slow query log file. The
+    argument will be treated as a decimal value with microsecond precision
+  - slave-max-statement-time: A query that has taken more than
+    slave_max_statement_time seconds to run on the slave will be aborted. The
+    argument will be treated as a decimal value with microsecond precision. A
+    value of 0 (default) means no timeout
+  - system-versioning-insert-history: Allows direct inserts into ROW_START and
+    ROW_END columns if secure_timestamp allows changing @@timestamp
+  - wsrep-allowlist: Allowed IP addresses split by comma delimiter
+  - wsrep-status-file: wsrep status output filename
+
+  Changed behavior in server variables in 10.11 (compared to 10.6):
+  - explicit-defaults-for-timestamp: enabled by default
+  - optimizer-prune-level: defaults to 2 (instead of 1)
+  - old-mode: new options IGNORE_INDEX_ONLY_FOR_JOIN and COMPAT_5_1_CHECKSUM
+  - wsrep-mode: new option BF_ABORT_MARIABACKUP
+  - read-only: changing value requires 'READ ONLY ADMIN' privilege
+
+  One of the most important performance related server variables
+  'innodb_log_file_size' is now dynamic so it can be changed without having to
+  restart the server.
+
+  Removed in 10.11 (compared to 10.6):
+  - innodb-log-write-ahead-size: the physical block size of the underlying
+    storage is instead detected and used
+  - wsrep-replicate-myisam: use wsrep_mode instead
+  - wsrep-strict-ddl: use wsrep_mode instead
+
+  Deprecated server variables:
+  - innodb_change_buffering
+  - innodb-buffer-pool-chunk-size: defaults to 0 (instead of 134217728) in
+    server variables because the server automatically sizes it
+  - keep_files_on_create:	orphan files are now deleted automatically, so this
+    setting should never be needed
+
+  Note also that the MariaDB client settings have changed to now use SSL/TLS
+  by default.

+mariadb (1:10.11.1-1) unstable; urgency=medium
+
+  Version suffixed packages (e.g. mariadb-server-10.6) have now been deprecated
+  as it made maintenance complicated and there was no known use cases or users
+  of the naming scheme, as multiple different major version MariaDB server
+  packages could not be co-installed anyway and source or the 'mariadb-server'
+  and 'mariadb-client' packages is easiest controlled by repositories and
+  package versioning, not versions in package *names*.

+   or video from https://peertube.debian.social/videos/watch/bb80cf53-d9ba-4ed9-b472-a21238fb67f5.
+
+   Quick summary:
+   - Service name is now 'mariadb', e.g. /etc/init.d/mariadb and systemctl mariadb
+   - The main server binary is now running as 'mariadbd' instead of old 'mysqld'
+   - Many commands are now mariadb-* instead of old mysql*, but old names
+     continue to work as symlinks
+   - Referencing the /etc/mysql/debian.cnf file is not advised anymore. It will
+     be deprecated in a future Debian release and has been obsolete anyway for
+     several years now since MariaDB in Debian introduced Unix socket
+     authentication for the root account in 2015.
+
+   MariaDB 10.5 has been tested to be backwards compatible with all previous
+   versions of MariaDB and all previous versions of MySQL up until version 5.7.
+   Note that MySQL 8.0 introduces significant backwards incompatible changes
+   compared to MySQL 5.7, and thus in-place binary upgrades from MySQL 8.0 to
+   MariaDB 10.5 are not possible, but sysadmins need to upgrade by exporting and
+   importing SQL dumps of their databases.
+
+   If you encounter any bugs, please make sure your bug report is of highest
+   standards so we can quickly reproduce and fix the issue. Even better if you
+   find the solution yourself, and can submit it as a Merge Request at
+   https://salsa.debian.org/mariadb-team/mariadb-10.5/
+
+   If you appreciate the Debian packaging work done, please star us on Salsa!

+
+mariadb-10.1 (10.1.20-1) unstable; urgency=low
+
+    MariaDB is now the default MySQL variant in Debian, at version 10.1. The
+    Stretch release introduces a new mechanism for switching the default
+    variant, using metapackages created from the 'mysql-defaults' source
+    package. For example, installing the metapackage 'default-mysql-server' will
+    install 'mariadb-server-10.1'. Users who had 'mysql-server-5.5' or
+    'mysql-server-5.6' will have it removed and replaced by the MariaDB
+    equivalent. Similarly, installing 'default-mysql-client' will install
+    'mariadb-client-10.1'.
+
+    Note that the database binary data file formats are not backwards
+    compatible, so once you have upgraded to MariaDB 10.1 you will not be able
+    to switch back to any previous version of MariaDB or MySQL unless you have a
+    proper database dump. Therefore, before upgrading, please make backups of
+    all important databases with an appropriate tool such as 'mysqldump'.
+
+    The 'virtual-mysql-*' and 'default-mysql-*' packages will continue to exist.
+    MySQL continues to be maintained in Debian, in the unstable release. See the
+    page https://wiki.debian.org/Teams/MySQL more information about the
+    mysql-related software available in Debian.

+* MYSQL WON'T START OR STOP?
+============================
+
+The most common reasons the server does not start are:
+- AppArmor is enforced and something is wrong with the confinement profile.
+- Process supervisor scripts (init, systemd etc) fail to execute normally.
+- The configuration in /etc/mysql/... is wrong and prevents server from running.
+
+First check the contents of syslog (or systemd journal) and then check the
+logs at /var/log/mysql/ for any hints of what might be wrong.
+
+Examples:
+  grep mysql /var/log/syslog
+  journalctl -u mariadb
+
+
+* NEW SERVICE NAME, PROCESS AND BINARY NAMES IN MARIADB 10.5
+============================================================
+
+Starting form MariaDB 10.5, the default SysV init service name is 'mariadb',
+and can be accessed at path /etc/init.d/mariadb. The alias 'mysql' is only
+created on upgrades.
+
+On systemd services both 'mariadb' and alias 'mysql' are available all the time.
+
+Note that the new daemon name is 'mariadbd' instead of 'mysqld' and also most
+of the binaries have been renamed to mariadb-something, yet the old mysql-something
+name has been kept as a symbolic link to the new name for backwards compatibility.
+
+
+* NATIVE SYSTEMD SERVICE INTRODUCED IN MARIADB 10.1
+===================================================
+
+From MariaDB 10.1 onward the upstream mariadb.service and mariadb@.service are
+used to provide the full systemd experience. Some features available in
+traditional /etc/init.d/mysql have been changed. For details see
+https://mariadb.com/kb/en/mariadb/systemd/
+
+
+* MIXING PACKAGES FROM MARIADB.ORG AND OFFICIAL DEBIAN REPOSITORIES
+==================================================================
+
+Please note that the MariaDB packaging in official Debian repositories are of
+a completely new generation compared to the legacy packaging used in MariaDB.org
+repositories. You cannot mix and match MariaDB 10.1 packages from official
+Debian (or Ubuntu) repositories with packages from MariaDB.org repositories.
+Packages from the MariaDB.org repositories include the revision string '+maria'.
+
+If a MariaDB.org repository is enabled, learn to use apt pinning properly.
+
+Please do not file bugs in Debian regarding packages with '+maria' in the
+revision string.
+
+
+* ROOT USER AUTHENTICATION VIA UNIX SOCKET
+==========================================
+
+On new installs no root password is set and no debian-sys-maint user is
+created anymore. Instead the MariaDB root account is set to be authenticated
+using the Unix socket, e.g. any mysqld invocation by root or via sudo will
+let the user see the mysqld prompt.
+
+You may never ever delete the mysql user "root". Although it has no password
+is set, the unix_auth plugin ensure that it can only be run locally as the root
+user.
+
+The credentials in /etc/mysql/debian.cnf specify the user which is used by the
+init scripts to stop the server and perform log rotation. This used to be the
+debian-sys-maint user which is no longer used as root can run directly.
+
+If you have start/stop problems make sure that the /etc/mysql/debian.cnf file
+specifies the root user and no password. In the long run please stop using that
+file as is has been obsoleted.
+
+
+* MARIADB IS SECURE BY DEFAULT
+==============================
+
+MariaDB in Debian is secure by default, because:
+
+- It only listens to the localhost socket and cannot be accessed remotely unless
+  the sysadmin changes the configuration in /etc/mysql to allow so.
+- There is no debian-sys-maint with password in /etc/mysql/debian.cnf anymore.
+- There is no root account with password anymore. The system admin needs to
+  create one themselves if they need it. With no password, all issues related
+  to password management and password leaking are gone. Sysadmins can access
+  the database without a password simply by running 'sudo mysql' thanks to
+  socket based authentication, which detects the system root user and allows
+  them to use the mysqld console as the mysql root user. For details see
+  https://www.slideshare.net/ottokekalainen/less-passwords-more-security-unix-socket-authentication-and-other-mariadb-hardening-tips
+- There is no test database nor test accounts in the out-of-the-box Debian
+  installation.
+
+Therefore there is also no need to run the 'mysql_secure_installation'. In fact
+that script will try to do things that are already prevented, and might fail.
+
+
+* WHAT TO DO AFTER UPGRADES
+===========================
+
+The privilege tables are automatically updated so all there is left is read
+the release notes on https://mariadb.com/kb/en/release-notes/ to see if any
+changes affect custom apps.
+
+There should not be any need to run 'mysql_upgrade' manually, as the upgrade
+scripts do that automatically.
+
+
+* WHAT TO DO AFTER INSTALLATION
+===============================
+
+The MySQL manual describes certain steps to do at this stage in a separate
+chapter. They are not necessary as the Debian packages does them
+automatically.
+
+There should not be any need to run 'mysql_install_db' manually, as the install
+scripts do that automatically.
+
+The only thing that is left over for the admin is
+ - creating new users and databases
+ - read the rest of this text
+
+
+* NETWORKING
+============
+
+For security reasons, the Debian package has enabled networking only on the
+loop-back device using "bind-address" in /etc/mysql/my.cnf.  Check with
+"netstat -tlnp" where it is listening. If your connection is aborted
+immediately check your firewall rules or network routes.
+
+* WHERE IS THE DOCUMENTATION?
+=============================
+
+https://mariadb.com/kb
+
+
+* PASSWORDS
+===========
+
+It is recommended you create additional admin users for your database
+administration needs in addition to the default root user.
+
+If your local Unix account is the one you want to have local super user
+access on your database with you can create the following account that will
+only work for the local Unix user connecting to the database locally.
+
+  sudo /usr/bin/mysql -e "GRANT ALL ON *.* TO '$USER'@'localhost' IDENTIFIED VIA unix_socket WITH GRANT OPTION"
+
+To create a local machine account username=USERNAME with a password:
+
+  sudo /usr/bin/mysql -e "GRANT ALL ON *.* TO 'USERNAME'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION"
+
+To create a USERNAME user with password 'password' admin user that can access
+the DB server over the network:
+
+  sudo /usr/bin/mysql -e "GRANT ALL ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION"
+
+Scripts should run as a user who have the required grants and be identified via unix_socket.
+
+It is wise to run scripts as the "mysql" system user. Like root,
+mysql@localhost is created by default to have all privileges in MariaDB
+and to use unix_socket authentication. But scripts running under "mysql"
+won't have system-wide root so they won't be able to corrupt your system.
+
+If you are too tired to type the password in every time and unix_socket auth
+doesn't suit your needs, you can store it in the file $HOME/.my.cnf. It should
+be chmod 0600 (-rw------- username usergroup .my.cnf) to ensure that nobody else
+can read it.  Every other configuration parameter can be stored there, too.
+
+For more information in the MariaDB manual in/usr/share/doc/mariadb-doc or
+https://mariadb.com/kb/en/configuring-mariadb-with-mycnf/.
+
+
+* FURTHER NOTES ON REPLICATION
+==============================
+
+If the MySQL server is acting as a replication slave, you should not
+set --tmpdir to point to a directory on a memory-based file system or to
+a directory that is cleared when the server host restarts. A replication
+slave needs some of its temporary files to survive a machine restart so
+that it can replicate temporary tables or LOAD DATA INFILE operations. If
+files in the temporary file directory are lost when the server restarts,
+replication fails.
+
+
+* DOWNGRADING
+=============
+
+Unsupported. Period.
+
+You might get lucky downgrading a few minor versions without issued. Take a
+backup first. If you break it you get to keep both pieces. Do a restore from
+backup or upgrade to the previous version.
+
+If doing a major version downgrade, take a mysqldump/maria-backup consistent
+backup using the current version and reload after downgrading and purging
+existing databases.
+
+
+* BACKUPS
+=========
+
+Backups save jobs. Don't get caught without one.

+Subject: [PATCH] Properly introduce wsrep_sst_backup script in project
+ packaging
+
+The script wsrep_sst_backup was introduced on MariaDB 10.3 in commit
+9b2fa2a. The new script was automatically included in RPM packages but not
+in Debian packages (which started to fail on waring about stray file).
+
+Include wsrep_sst_backup in the mariadb-server-10.{3..8} package, and
+also include a stub man page so that packaging of a new script is complete.

+Subject: [PATCH] Fix a stack overflow in pinbox allocator
+
+MariaDB supports a "wait-free concurrent allocator based on pinning addresses".
+In `lf_pinbox_real_free()` it tries to sort the pinned addresses for better
+performance to use binary search during "real free". `alloca()` was used to
+allocate stack memory and copy addresses.
+
+To prevent a stack overflow when allocating the stack memory the function checks
+if there's enough stack space. However, the available stack size was calculated
+inaccurately which eventually caused database crash due to stack overflow.
+
+The crash was seen on MariaDB 10.6.11 but the same code defect exists on all
+MariaDB versions.
+
+A similar issue happened previously and the fix in fc2c1e43 was to add a
+`ALLOCA_SAFETY_MARGIN` which is 8192 bytes. However, that safety margin is not
+enough during high connection workloads.
+
+MySQL also had a similar issue and the fix
+https://github.com/mysql/mysql-server/commit/b086fda was to remove the use of
+`alloca` and replace qsort approach by a linear scan through all pointers (pins)
+owned by each thread.
+
+This commit is mostly the same as it is the only way to solve this issue as:
+1. Frame sizes in different architecture can be different.
+2. Number of active (non-null) pinned addresses varies, so the frame
+   size for the recursive sorting function `msort_with_tmp` is also hard
+   to predict.
+3. Allocating big memory blocks in stack doesn't seem to be a very good
+   practice.
+
+For further details see the mentioned commit in MySQL and the inline comments.
+
+All new code of the whole pull request, including one or several files
+that are either new files or modified ones, are contributed under the
+BSD-new license. I am contributing on behalf of my employer Amazon Web
+Services, Inc.

+# Merged in RocksDB 6.19.3, but not updated into MariaDB yet
+Bug: https://github.com/facebook/rocksdb/issues/7035
+Author: Otto Kekäläinen <otto@kekalainen.net>
+Subject: Make RocksDB build reproducible
+
+The RocksDB binary included a string with the build timestamp:
+> rocksdb_build_git_date:@2021-05-23·16:04:38@
+
+As this changes from build to build, it makes the builds unreproducible.
+Simply removing it solves the issue.
+
+This temporary fix can be removed when a proper fix already done in upstream
+lands in MariaDB when the RocksDB submodule is updated to a newer release.

+Usage: /usr/bin/mariadb [OPTIONS] [database]
+
+Default options are read from the following files in the given order:
+/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf 
+The following groups are read: mysql mariadb-client client client-server client-mariadb
+The following options may be given as the first argument:
+--print-defaults          Print the program argument list and exit.
+--no-defaults             Don't read default options from any option file.
+The following specify which files/extra groups are read (specified before remaining options):
+--defaults-file=#         Only read default options from the given file #.
+--defaults-extra-file=#   Read this file after the global files are read.
+--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
+
+  -?, --help          Display this help and exit.
+  -I, --help          Synonym for -?
+  --abort-source-on-error 
+                      Abort 'source filename' operations in case of errors
+  --auto-rehash       Enable automatic rehashing. One doesn't need to use
+                      'rehash' to get table and field completion, but startup
+                      and reconnecting may take a longer time. Disable with
+                      --disable-auto-rehash.
+                      (Defaults to on; use --skip-auto-rehash to disable.)
+  -A, --no-auto-rehash 
+                      No automatic rehashing. One has to use 'rehash' to get
+                      table and field completion. This gives a quicker start of
+                      mysql and disables rehashing on reconnect.
+  --auto-vertical-output 
+                      Automatically switch to vertical output mode if the
+                      result is wider than the terminal width.
+  -B, --batch         Don't use history file. Disable interactive behavior.
+                      (Enables --silent.)
+  --binary-as-hex     Print binary data as hex
+  --character-sets-dir=name 
+                      Directory for character set files.
+  --column-type-info  Display column type information.
+  -c, --comments      Preserve comments. Send comments to the server. The
+                      default is --skip-comments (discard comments), enable
+                      with --comments.
+  -C, --compress      Use compression in server/client protocol.
+  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
+  --debug-check       Check memory and open file usage at exit.
+  -T, --debug-info    Print some debug info at exit.
+  -D, --database=name Database to use.
+  --default-character-set=name

+  -s, --silent        Be more silent. Print results with a tab as separator,
+                      each row on new line.
+  -S, --socket=name   The socket file to use for connection.
+  --ssl               Enable SSL for connection (automatically enabled with
+                      other flags).
+                      (Defaults to on; use --skip-ssl to disable.)

+  --binary-mode       Binary mode allows certain character sequences to be
+                      processed as data that would otherwise be treated with a
+                      special meaning by the parser. Specifically, this switch
+                      turns off parsing of all client commands except \C and
+                      DELIMITER in non-interactive mode (i.e., when binary mode
+                      is combined with either 1) piped input, 2) the --batch
+                      mysql option, or 3) the 'source' command). Also, in
+                      binary mode, occurrences of '\r\n' and ASCII '\0' are
+                      preserved within strings, whereas by default, '\r\n' is
+                      translated to '\n' and '\0' is disallowed in user input.
+  --connect-expired-password 
+                      Notify the server that this client is prepared to handle
+                      expired password sandbox mode even if --batch was
+                      specified.

+Starts the MariaDB database server.
+
+Usage: /usr/sbin/mariadbd [OPTIONS]
+
+Default options are read from the following files in the given order:
+/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf 
+The following groups are read: mysqld server mysqld-10.11 mariadb mariadb-10.11 mariadbd mariadbd-10.11 client-server galera
+The following options may be given as the first argument:
+--print-defaults          Print the program argument list and exit.
+--no-defaults             Don't read default options from any option file.
+The following specify which files/extra groups are read (specified before remaining options):
+--defaults-file=#         Only read default options from the given file #.
+--defaults-extra-file=#   Read this file after the global files are read.
+--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.
+
+  --allow-suspicious-udfs 
+                      Allows use of user-defined functions (UDFs) consisting of
+                      only one symbol xxx() without corresponding xxx_init() or
+                      xxx_deinit(). That also means that one can load any
+                      function from any library, for example exit() from
+                      libc.so
+  --alter-algorithm[=name] 
+                      Specify the alter table algorithm. One of: DEFAULT, COPY,
+                      INPLACE, NOCOPY, INSTANT
+  --analyze-sample-percentage=# 
+                      Percentage of rows from the table ANALYZE TABLE will
+                      sample to collect table statistics. Set to 0 to let
+                      MariaDB decide what percentage of rows to sample.
+  -a, --ansi          Use ANSI SQL syntax instead of MySQL syntax. This mode
+                      will also set transaction isolation level 'serializable'.
+  --aria-block-size=# Block size to be used for Aria index pages.
+  --aria-checkpoint-interval=# 
+                      Interval between tries to do an automatic checkpoints. In
+                      seconds; 0 means 'no automatic checkpoints' which makes
+                      sense only for testing.
+  --aria-checkpoint-log-activity=# 
+                      Number of bytes that the transaction log has to grow
+                      between checkpoints before a new checkpoint is written to
+                      the log.
+  --aria-encrypt-tables 
+                      Encrypt tables (only for tables with ROW_FORMAT=PAGE
+                      (default) and not FIXED/DYNAMIC)
+  --aria-force-start-after-recovery-failures=# 
+                      Number of consecutive log recovery failures after which
+                      logs will be automatically deleted to cure the problem; 0
+                      (the default) disables the feature.
+  --aria-group-commit=name 
+                      Specifies Aria group commit mode. Possible values are
+                      "none" (no group commit), "hard" (with waiting to actual
+                      commit), "soft" (no wait for commit (DANGEROUS!!!))
+  --aria-group-commit-interval=# 
+                      Interval between commits in microseconds (1/1000000 sec).
+                      0 stands for no waiting for other threads to come and do
+                      a commit in "hard" mode and no sync()/commit at all in
+                      "soft" mode.  Option has only an effect if
+                      aria_group_commit is used
+  --aria-log-dir-path=name 
+                      Path to the directory where to store transactional log
+  --aria-log-file-size=# 
+                      Limit for transaction log size
+  --aria-log-purge-type=name 
+                      Specifies how Aria transactional log will be purged. One
+                      of: immediate, external, at_flush
+  --aria-max-sort-file-size=# 
+                      Don't use the fast sort index method to created index if
+                      the temporary file would get bigger than this.
+  --aria-page-checksum 
+                      Maintain page checksums (can be overridden per table with
+                      PAGE_CHECKSUM clause in CREATE TABLE)
+                      (Defaults to on; use --skip-aria-page-checksum to disable.)
+  --aria-pagecache-age-threshold=# 
+                      This characterizes the number of hits a hot block has to
+                      be untouched until it is considered aged enough to be
+                      downgraded to a warm block. This specifies the percentage
+                      ratio of that number of hits to the total number of
+                      blocks in the page cache.
+  --aria-pagecache-buffer-size=# 
+                      The size of the buffer used for index blocks for Aria
+                      tables. Increase this to get better index handling (for
+                      all reads and multiple writes) to as much as you can
+                      afford.
+  --aria-pagecache-division-limit=# 
+                      The minimum percentage of warm blocks in key cache
+  --aria-pagecache-file-hash-size=# 
+                      Number of hash buckets for open and changed files.  If
+                      you have a lot of Aria files open you should increase
+                      this for faster flush of changes. A good value is
+                      probably 1/10 of number of possible open Aria files.
+  --aria-recover-options[=name] 
+                      Specifies how corrupted tables should be automatically
+                      repaired. Any combination of: NORMAL, BACKUP, FORCE, 
+                      QUICK, OFF
+  Use 'ALL' to set all combinations.
+  --aria-repair-threads=# 
+                      Number of threads to use when repairing Aria tables. The
+                      value of 1 disables parallel repair.
+  --aria-sort-buffer-size=# 
+                      The buffer that is allocated when sorting the index when
+                      doing a REPAIR or when creating indexes with CREATE INDEX
+                      or ALTER TABLE.
+  --aria-stats-method=name 
+                      Specifies how Aria index statistics collection code
+                      should treat NULLs. One of: nulls_unequal, nulls_equal, 
+                      nulls_ignored
+  --aria-sync-log-dir=name 
+                      Controls syncing directory after log file growth and new
+                      file creation. One of: NEVER, NEWFILE, ALWAYS
+  --auto-increment-increment[=#] 
+                      Auto-increment columns are incremented by this
+  --auto-increment-offset[=#] 
+                      Offset added to Auto-increment columns. Used when
+                      auto-increment-increment != 1
+  --autocommit        Set default value for autocommit (0 or 1)
+                      (Defaults to on; use --skip-autocommit to disable.)
+  --automatic-sp-privileges 
+                      Creating and dropping stored procedures alters ACLs
+                      (Defaults to on; use --skip-automatic-sp-privileges to disable.)
+  --back-log=#        The number of outstanding connection requests MariaDB can
+                      have. This comes into play when the main MariaDB thread
+                      gets very many connection requests in a very short time
+                      (Automatically configured unless set explicitly)
+  -b, --basedir=name  Path to installation directory. All paths are usually
+                      resolved relative to this
+  --big-tables        Old variable, which if set to 1, allows large result sets
+                      by saving all temporary sets to disk, avoiding 'table
+                      full' errors. No longer needed, as the server now handles
+                      this automatically.
+  --bind-address=name IP address to bind to. Several addresses may be
+                      specified, separated by a comma (,).
+  --binlog-alter-two-phase 
+                      When set, split ALTER at binary logging into 2
+                      statements: START ALTER and COMMIT/ROLLBACK ALTER
+  --binlog-annotate-row-events 
+                      Tells the master to annotate RBR events with the
+                      statement that caused these events
+                      (Defaults to on; use --skip-binlog-annotate-row-events to disable.)
+  --binlog-cache-size=# 
+                      The size of the transactional cache for updates to
+                      transactional engines for the binary log. If you often
+                      use transactions containing many statements, you can
+                      increase this to get more performance
+  --binlog-checksum=name 
+                      Type of BINLOG_CHECKSUM_ALG. Include checksum for log
+                      events in the binary log. One of: NONE, CRC32
+  --binlog-commit-wait-count=# 
+                      If non-zero, binlog write will wait at most
+                      binlog_commit_wait_usec microseconds for at least this
+                      many commits to queue up for group commit to the binlog.
+                      This can reduce I/O on the binlog and provide increased
+                      opportunity for parallel apply on the slave, but too high
+                      a value will decrease commit throughput.
+  --binlog-commit-wait-usec=# 
+                      Maximum time, in microseconds, to wait for more commits
+                      to queue up for binlog group commit. Only takes effect if
+                      the value of binlog_commit_wait_count is non-zero.
+  --binlog-direct-non-transactional-updates 
+                      Causes updates to non-transactional engines using
+                      statement format to be written directly to binary log.
+                      Before using this option make sure that there are no
+                      dependencies between transactional and non-transactional
+                      tables such as in the statement INSERT INTO t_myisam
+                      SELECT * FROM t_innodb; otherwise, slaves may diverge
+                      from the master.
+  --binlog-do-db=name Tells the master it should log updates for the specified
+                      database, and exclude all others not explicitly
+                      mentioned.
+  --binlog-expire-logs-seconds=# 
+                      If non-zero, binary logs will be purged after
+                      binlog_expire_logs_seconds seconds; It and
+                      expire_logs_days are linked, such that changes in one are
+                      converted into the other. Possible purges happen at
+                      startup and at binary log rotation.
+  --binlog-file-cache-size=# 
+                      The size of file cache for the binary log
+  --binlog-format=name 
+                      What form of binary logging the master will use: either
+                      ROW for row-based binary logging, STATEMENT for
+                      statement-based binary logging, or MIXED. MIXED is
+                      statement-based binary logging except for those
+                      statements where only row-based is correct: those which
+                      involve user-defined functions (i.e. UDFs) or the UUID()
+                      function; for those, row-based binary logging is
+                      automatically used.
+  --binlog-ignore-db=name 
+                      Tells the master that updates to the given database
+                      should not be logged to the binary log.
+  --binlog-optimize-thread-scheduling 
+                      Run fast part of group commit in a single thread, to
+                      optimize kernel thread scheduling. On by default. Disable
+                      to run each transaction in group commit in its own
+                      thread, which can be slower at very high concurrency.
+                      This option is mostly for testing one algorithm versus
+                      the other, and it should not normally be necessary to
+                      change it.
+                      (Defaults to on; use --skip-binlog-optimize-thread-scheduling to disable.)
+  --binlog-row-event-max-size=# 
+                      The maximum size of a row-based binary log event in
+                      bytes. Rows will be grouped into events smaller than this
+                      size if possible. The value has to be a multiple of 256.
+  --binlog-row-image=name 
+                      Controls whether rows should be logged in 'FULL',
+                      'NOBLOB' or 'MINIMAL' formats. 'FULL', means that all
+                      columns in the before and after image are logged.
+                      'NOBLOB', means that mysqld avoids logging blob columns
+                      whenever possible (eg, blob column was not changed or is
+                      not part of primary key). 'MINIMAL', means that a PK
+                      equivalent (PK columns or full row if there is no PK in
+                      the table) is logged in the before image, and only
+                      changed columns are logged in the after image. (Default:
+                      FULL).
+  --binlog-row-metadata=name 
+                      Controls whether metadata is logged using FULL , MINIMAL
+                      format and NO_LOG.FULL causes all metadata to be logged;
+                      MINIMAL means that only metadata actually required by
+                      slave is logged; NO_LOG NO metadata will be
+                      logged.Default: NO_LOG.
+  --binlog-stmt-cache-size=# 
+                      The size of the statement cache for updates to
+                      non-transactional engines for the binary log. If you
+                      often use statements updating a great number of rows, you
+                      can increase this to get more performance.
+  --bootstrap         Used by mysql installation scripts.
+  --bulk-insert-buffer-size=# 
+                      Size of tree cache used in bulk insert optimisation. Note
+                      that this is a limit per thread!
+  --character-set-client-handshake 
+                      Don't ignore client side character set value sent during
+                      handshake.
+                      (Defaults to on; use --skip-character-set-client-handshake to disable.)
+  --character-set-filesystem=name 
+                      Set the filesystem character set.
+  -C, --character-set-server=name 
+                      Set the default character set.
+  --character-sets-dir=name 
+                      Directory where character sets are
+  -r, --chroot=name   Chroot mysqld daemon during startup.
+  --collation-server=name 
+                      Set the default collation.
+  --column-compression-threshold=# 
+                      Minimum column data length eligible for compression
+  --column-compression-zlib-level=# 
+                      zlib compression level (1 gives best speed, 9 gives best
+                      compression)
+  --column-compression-zlib-strategy=name 
+                      The strategy parameter is used to tune the compression
+                      algorithm. Use the value DEFAULT_STRATEGY for normal
+                      data, FILTERED for data produced by a filter (or
+                      predictor), HUFFMAN_ONLY to force Huffman encoding only
+                      (no string match), or RLE to limit match distances to one
+                      (run-length encoding). Filtered data consists mostly of
+                      small values with a somewhat random distribution. In this
+                      case, the compression algorithm is tuned to compress them
+                      better. The effect of FILTERED is to force more Huffman
+                      coding and less string matching; it is somewhat
+                      intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
+                      RLE is designed to be almost as fast as HUFFMAN_ONLY, but
+                      give better compression for PNG image data. The strategy
+                      parameter only affects the compression ratio but not the
+                      correctness of the compressed output even if it is not
+                      set appropriately. FIXED prevents the use of dynamic
+                      Huffman codes, allowing for a simpler decoder for special
+                      applications.
+  --column-compression-zlib-wrap 
+                      Generate zlib header and trailer and compute adler32
+                      check value. It can be used with storage engines that
+                      don't provide data integrity verification to detect data
+                      corruption.
+  --completion-type=name 
+                      The transaction completion type. One of: NO_CHAIN, CHAIN,

+  --concurrent-insert[=name] 
+                      Use concurrent insert with MyISAM. One of: NEVER, AUTO, 
+                      ALWAYS
+  --connect-timeout=# The number of seconds the mysqld server is waiting for a

+  --debug-no-thread-alarm 
+                      Disable system thread alarm calls. Disabling it may be

+  --debug-sporadic-binlog-dump-fail 
+                      Option used by mysql-test for debugging and testing of
+                      replication.
+  --default-password-lifetime=# 
+                      This defines the global password expiration policy. 0
+                      means automatic password expiration is disabled. If the
+                      value is a positive integer N, the passwords must be
+                      changed every N days. This behavior can be overridden
+                      using the password expiration options in ALTER USER.
+  --default-regex-flags=name 
+                      Default flags for the regex library. Any combination of: 
+                      DOTALL, DUPNAMES, EXTENDED, EXTENDED_MORE, EXTRA, 
+                      MULTILINE, UNGREEDY
+  Use 'ALL' to set all combinations.

+  --default-week-format=# 
+                      The default week format used by WEEK() functions
+  --delay-key-write[=name] 
+                      Specifies how MyISAM tables handles CREATE TABLE
+                      DELAY_KEY_WRITE. If set to ON, the default, any DELAY KEY
+                      WRITEs are honored. The key buffer is then flushed only
+                      when the table closes, speeding up writes. MyISAM tables
+                      should be automatically checked upon startup in this
+                      case, and --external locking should not be used, as it
+                      can lead to index corruption. If set to OFF, DELAY KEY
+                      WRITEs are ignored, while if set to ALL, all new opened
+                      tables are treated as if created with DELAY KEY WRITEs
+                      enabled.
+  --delayed-insert-limit=# 
+                      After inserting delayed_insert_limit rows, the INSERT
+                      DELAYED handler will check if there are any SELECT
+                      statements pending. If so, it allows these to execute
+                      before continuing.
+  --delayed-insert-timeout=# 
+                      How long a INSERT DELAYED thread should wait for INSERT

+                      What size queue (in rows) should be allocated for
+                      handling INSERT DELAYED. If the queue becomes full, any
+                      client that does INSERT DELAYED will wait until there is
+                      room in the queue again
+  --des-key-file=name Load keys for des_encrypt() and des_encrypt from given
+                      file.
+  --disconnect-on-expired-password 
+                      This variable controls how the server handles clients
+                      that are not aware of the sandbox mode. If enabled, the
+                      server disconnects the client, otherwise the server puts
+                      the client in a sandbox mode.
+  --div-precision-increment=#

+                      The optimizer will use existing index statistics instead
+                      of doing index dives for equality ranges if the number of
+                      equality ranges for the index is larger than or equal to

+                      be untouched until it is considered aged enough to be

+  --key-cache-file-hash-size=# 
+                      Number of hash buckets for open and changed files.  If
+                      you have a lot of MyISAM files open you should increase
+                      this for faster flush of changes. A good value is
+                      probably 1/10 of number of possible open MyISAM files.
+  --key-cache-segments=# 
+                      The number of segments in a key cache
+  -L, --language=name Client error messages in given language. May be given as

+                      Timeout in seconds to wait for a lock before returning an
+                      error.
+  --log-basename=name Basename for all log files and the .pid file. This sets
+                      all log file names at once (in 'datadir') and is normally
+                      the only option you need for specifying log files. Sets
+                      names for --log-bin, --log-bin-index, --relay-log,
+                      --relay-log-index, --general-log-file,
+                      --log-slow-query-file, --log-error-file, and --pid-file
+  --log-bin[=name]    Log update queries in binary format. Optional argument
+                      should be name for binary log. If not given
+                      'datadir'/'log-basename'-bin or 'datadir'/mysql-bin will
+                      be used (the later if --log-basename is not specified).
+                      We strongly recommend to use either --log-basename or
+                      specify a filename to ensure that replication doesn't
+                      stop if the real hostname of the computer changes.
+  --log-bin-compress  Whether the binary log can be compressed
+  --log-bin-compress-min-len[=#] 
+                      Minimum length of sql statement(in statement mode) or
+                      record(in row mode)that can be compressed.
+  --log-bin-index=name 
+                      File that holds the names for last binary log files.
+  --log-bin-trust-function-creators 
+                      If set to FALSE (the default), then when --log-bin is

+                      allowed only to users having the SUPER privilege and only
+                      if this stored function (trigger) may not break binary
+                      logging. Note that if ALL connections to this server
+                      ALWAYS use row-based binary logging, the security issues
+                      do not exist and the binary logging cannot break, so you
+                      can safely set this to TRUE
+  --log-ddl-recovery=name 
+                      Path to file used for recovery of DDL statements after a
+                      crash
+  --log-disabled-statements=name 
+                      Don't log certain types of statements to general log. Any
+                      combination of: slave, sp
+  Use 'ALL' to set all combinations.
+  --log-error[=name]  Log errors to file (instead of stdout).  If file name is
+                      not specified then 'datadir'/'log-basename'.err or the
+                      'pid-file' path with extension .err is used
+  --log-isam[=name]   Log all MyISAM changes to file.
+  --log-output=name   How logs should be written. Any combination of: NONE, 
+                      FILE, TABLE
+  Use 'ALL' to set all combinations.
+  --log-queries-not-using-indexes 
+                      Log queries that are executed without benefit of any
+                      index to the slow log if it is open. Same as

+  --log-short-format  Don't log extra information to update and slow-query
+                      logs.
+  --log-slave-updates Tells the slave to log the updates from the slave thread
+                      to the binary log. You will need to turn it on if you
+                      plan to daisy-chain the slaves.
+  --log-slow-admin-statements 
+                      Log slow OPTIMIZE, ANALYZE, ALTER and other
+                      administrative statements to the slow log if it is open. 
+                      Resets or sets the option 'admin' in
+                      log_slow_disabled_statements
+                      (Defaults to on; use --skip-log-slow-admin-statements to disable.)
+  --log-slow-disabled-statements=name 
+                      Don't log certain types of statements to slow log. Any
+                      combination of: admin, call, slave, sp
+  Use 'ALL' to set all combinations.
+  --log-slow-filter=name 
+                      Log only certain types of queries to the slow log. If
+                      variable empty all kind of queries are logged.  All types
+                      are bound by slow_query_time, except 'not_using_index'
+                      which is always logged if enabled. Any combination of:

+                      Tells the slave thread to not replicate to the specified
+                      database. To specify more than one database to ignore,
+                      use the directive multiple times, once for each database.
+                      This option will not work if you use cross database
+                      updates. If you need cross database updates to work, make
+                      sure you have 3.23.28 or later, and use
+                      replicate-wild-ignore-table=db_name.%. 
+  --replicate-ignore-table=name 
+                      Tells the slave thread to not replicate to the specified
+                      table. To specify more than one table to ignore, use the
+                      directive multiple times, once for each table. This will
+                      work for cross-database updates, in contrast to
+                      replicate-ignore-db.
+  --replicate-rewrite-db=name 
+                      Updates to a database with a different name than the
+                      original. Example:
+                      replicate-rewrite-db=master_db_name->slave_db_name.
+  --replicate-same-server-id 
+                      In replication, if set to 1, do not skip events having
+                      our server id. Default value is 0 (to break infinite
+                      loops in circular replication). Can't be set to 1 if
+                      --log-slave-updates is used.
+  --replicate-wild-do-table=name 
+                      Tells the slave thread to restrict replication to the
+                      tables that match the specified wildcard pattern. To
+                      specify more than one table, use the directive multiple
+                      times, once for each table. This will work for
+                      cross-database updates. Example:
+                      replicate-wild-do-table=foo%.bar% will replicate only
+                      updates to tables in all databases that start with foo
+                      and whose table names start with bar.
+  --replicate-wild-ignore-table=name 
+                      Tells the slave thread to not replicate to the tables
+                      that match the given wildcard pattern. To specify more
+                      than one table to ignore, use the directive multiple
+                      times, once for each table. This will work for
+                      cross-database updates. Example:
+                      replicate-wild-ignore-table=foo%.bar% will not do updates
+                      to tables in databases that start with foo and whose
+                      table names start with bar.
+  --report-host=name  Hostname or IP of the slave to be reported to the master
+                      during slave registration. Will appear in the output of
+                      SHOW SLAVE HOSTS. Leave unset if you do not want the
+                      slave to register itself with the master. Note that it is
+                      not sufficient for the master to simply read the IP of
+                      the slave off the socket once the slave connects. Due to
+                      NAT and other routing issues, that IP may not be valid
+                      for connecting to the slave from the master or other
+                      hosts
+  --report-password=name 
+                      The account password of the slave to be reported to the
+                      master during slave registration
+  --report-port=#     Port for connecting to slave reported to the master
+                      during slave registration. Set it only if the slave is
+                      listening on a non-default port or if you have a special
+                      tunnel from the master or other clients to the slave. If
+                      not sure, leave this option unset
+  --report-user=name  The account user name of the slave to be reported to the
+                      master during slave registration
+  --require-secure-transport 
+                      When this option is enabled, connections attempted using
+                      insecure transport will be rejected. Secure transports
+                      are SSL/TLS, Unix sockets or named pipes.

+  --rpl-semi-sync-master-wait-point=name 
+                      Should transaction wait for semi-sync ack after having
+                      synced binlog, or after having committed in storage

+  --rpl-semi-sync-slave-kill-conn-timeout[=#] 
+                      Timeout for the mysql connection used to kill the slave
+                      io_thread's connection on master. This timeout comes into
+                      play when stop slave is executed.
+  --rpl-semi-sync-slave-trace-level=# 
+                      The tracing level for semi-sync replication.
+  --safe-mode         Skip some optimize stages (for testing). Deprecated.
+  --safe-user-create  Don't allow new user creation by the user who has no

+  --secure-auth       Disallow authentication for accounts that have old
+                      (pre-4.1) passwords
+                      (Defaults to on; use --skip-secure-auth to disable.)
+  --secure-file-priv=name

+  --secure-timestamp=name 
+                      Restricts direct setting of a session timestamp. Possible
+                      levels are: YES - timestamp cannot deviate from the
+                      system clock, REPLICATION - replication thread can adjust
+                      timestamp to match the master's, SUPER - a user with this
+                      privilege and a replication thread can adjust timestamp,
+                      NO - historical behavior, anyone can modify session
+                      timestamp
+  --sequence[=name]   Enable or disable SEQUENCE plugin. One of: ON, OFF, FORCE
+                      (don't start if the plugin fails to load),
+                      FORCE_PLUS_PERMANENT (like FORCE, but the plugin can not

+  --server-id=#       Uniquely identifies the server instance in the community
+                      of replication partners
+  --session-track-schema 
+                      Track changes to the default schema.

+                      Track changes to the transaction attributes. OFF to
+                      disable; STATE to track just transaction state (Is there
+                      an active transaction? Does it have any data? etc.);
+                      CHARACTERISTICS to track transaction state and report all

+                      Show user and password in SHOW SLAVE HOSTS on this
+                      master.
+  --silent-startup    Don't print [Note] to the error log during startup.
+  --skip-grant-tables Start without grant tables. This gives all users FULL
+                      ACCESS to all tables.
+  --skip-host-cache   Don't cache host names.
+  --skip-name-resolve Don't resolve hostnames. All hostnames are IP's or

+  --slave-ddl-exec-mode=name 
+                      How replication events should be executed. Legal values
+                      are STRICT and IDEMPOTENT (default). In IDEMPOTENT mode,
+                      replication will not stop for DDL operations that are
+                      idempotent. This means that CREATE TABLE is treated as
+                      CREATE TABLE OR REPLACE and DROP TABLE is treated as DROP
+                      TABLE IF EXISTS.
+  --slave-domain-parallel-threads=# 
+                      Maximum number of parallel threads to use on slave for
+                      events in a single replication domain. When using
+                      multiple domains, this can be used to limit a single
+                      domain from grabbing all threads and thus stalling other
+                      domains. The default of 0 means to allow a domain to grab
+                      as many threads as it wants, up to the value of
+                      slave_parallel_threads.
+  --slave-exec-mode=name 
+                      How replication events should be executed. Legal values
+                      are STRICT (default) and IDEMPOTENT. In IDEMPOTENT mode,
+                      replication will not stop for operations that are
+                      idempotent. For example, in row based replication
+                      attempts to delete rows that doesn't exist will be
+                      ignored. In STRICT mode, replication will stop on any
+                      unexpected difference between the master and the slave.
+  --slave-load-tmpdir=name 
+                      The location where the slave should put its temporary

+  --slave-max-allowed-packet=# 
+                      The maximum packet length to sent successfully from the

+  --slave-max-statement-time=# 
+                      A query that has taken more than slave_max_statement_time
+                      seconds to run on the slave will be aborted. The argument
+                      will be treated as a decimal value with microsecond
+                      precision. A value of 0 (default) means no timeout
+  --slave-net-timeout=# 
+                      Number of seconds to wait for more data from any
+                      master/slave connection before aborting the read
+  --slave-parallel-max-queued=# 
+                      Limit on how much memory SQL threads should use per
+                      parallel replication thread when reading ahead in the
+                      relay log looking for opportunities for parallel
+                      replication. Only used when --slave-parallel-threads > 0.
+  --slave-parallel-mode=name 
+                      Controls what transactions are applied in parallel when
+                      using --slave-parallel-threads. Possible values:
+                      "optimistic" tries to apply most transactional DML in
+                      parallel, and handles any conflicts with rollback and
+                      retry. "conservative" limits parallelism in an effort to
+                      avoid any conflicts. "aggressive" tries to maximise the
+                      parallelism, possibly at the cost of increased conflict
+                      rate. "minimal" only parallelizes the commit steps of
+                      transactions. "none" disables parallel apply completely.
+  --slave-parallel-threads=# 
+                      If non-zero, number of threads to spawn to apply in
+                      parallel events on the slave that were group-committed on
+                      the master or were logged with GTID in different
+                      replication domains. Note that these threads are in
+                      addition to the IO and SQL threads, which are always
+                      created by a replication slave
+  --slave-parallel-workers=# 
+                      Alias for slave_parallel_threads
+  --slave-run-triggers-for-rbr=name 
+                      Modes for how triggers in row-base replication on slave
+                      side will be executed. Legal values are NO (default),
+                      YES, LOGGING and ENFORCE. NO means that trigger for RBR
+                      will not be running on slave. YES and LOGGING means that
+                      triggers will be running on slave, if there was not
+                      triggers running on the master for the statement. LOGGING
+                      also means results of that the executed triggers work
+                      will be written to the binlog. ENFORCE means that
+                      triggers will always be run on the slave, even if there
+                      are triggers on the master. ENFORCE implies LOGGING.
+  --slave-skip-errors=name 
+                      Tells the slave thread to continue replication when a
+                      query event returns an error from the provided list
+  --slave-sql-verify-checksum 
+                      Force checksum verification of replication events after
+                      reading them from relay log. Note: Events are always
+                      checksum-verified by slave on receiving them from the
+                      network before writing them to the relay log
+                      (Defaults to on; use --skip-slave-sql-verify-checksum to disable.)
+  --slave-transaction-retries=# 
+                      Number of times the slave SQL thread will retry a

+  --slave-transaction-retry-errors=name 
+                      Tells the slave thread to retry transaction for
+                      replication when a query event returns an error from the
+                      provided list. Deadlock error, elapsed lock wait timeout,

+  --slave-type-conversions=name 
+                      Set of slave type conversions that are enabled. If the
+                      variable is empty, no conversions are allowed and it is
+                      expected that the types match exactly. Any combination
