+Up-to-date instructions on MariaDB building on Windows can be found in http://kb.askmonty.org/en/building-mariadb-on-windows. 
 
-2.5.10. Installing MySQL from Source on Windows
-
-   These instructions describe how to build binaries from source for
-   MySQL 5.1 on Windows. Instructions are provided for building
-   binaries from a standard source distribution or from the Bazaar
-   tree that contains the latest development source.
-
-Note
-
-   The instructions here are strictly for users who want to test
-   MySQL on Microsoft Windows from the latest source distribution or
-   from the Bazaar tree. For production use, we do not advise using a
-   MySQL server built by yourself from source. Normally, it is best
-   to use precompiled binary distributions of MySQL that are built
-   specifically for optimal performance on Windows by Oracle
-   Corporation. Instructions for installing binary distributions are
-   available in Section 2.5, "Installing MySQL on Windows."
-
-   To build MySQL on Windows from source, you must satisfy the
-   following system, compiler, and resource requirements:
-
-     * Windows 2000, Windows XP, or newer version.
-       Windows Vista is supported when using Visual Studio 2005
-       provided you have installed the following updates:
-
-          + Microsoft Visual Studio 2005 Professional Edition - ENU
-            Service Pack 1 (KB926601)
-            (http://support.microsoft.com/?kbid=926601)
-
-          + Security Update for Microsoft Visual Studio 2005
-            Professional Edition - ENU (KB937061)
-            (http://support.microsoft.com/?kbid=937061)
-
-          + Update for Microsoft Visual Studio 2005 Professional
-            Edition - ENU (KB932232)
-            (http://support.microsoft.com/?kbid=932232)
-
-     * CMake, which can be downloaded from http://www.cmake.org.
-       After installing, modify your path to include the cmake
-       binary.
-
-     * Microsoft Visual C++ 2005 Express Edition, Visual Studio .Net
-       2003 (7.1), or Visual Studio 2005 (8.0) compiler system.
-
-     * If you are using Visual C++ 2005 Express Edition, you must
-       also install an appropriate Platform SDK. More information and
-       links to downloads for various Windows platforms is available
-       from
-       http://www.microsoft.com/downloads/details.aspx?familyid=0baf2
-       b35-c656-4969-ace8-e4c0c0716adb.
-
-     * If you are compiling from a Bazaar tree or making changes to
-       the parser, you need bison for Windows, which can be
-       downloaded from
-       http://gnuwin32.sourceforge.net/packages/bison.htm. Download
-       the package labeled "Complete package, excluding sources".
-       After installing the package, modify your path to include the
-       bison binary and ensure that this binary is accessible from
-       Visual Studio.
-
-     * Cygwin might be necessary if you want to run the test script
-       or package the compiled binaries and support files into a Zip
-       archive. (Cygwin is needed only to test or package the
-       distribution, not to build it.) Cygwin is available from
-       http://cygwin.com.
-
-     * 3GB to 5GB of disk space.
-
-   The exact system requirements for Visual Studio can be found here:
-   http://msdn.microsoft.com/vstudio/Previous/2003/sysreqs/default.as
-   px and
-   http://msdn.microsoft.com/vstudio/products/sysreqs/default.aspx
-
-   You also need a MySQL source distribution for Windows, which can
-   be obtained two ways:
-
-     * Obtain a source distribution packaged by Oracle Corporation.
-       These are available from http://dev.mysql.com/downloads/.
-
-     * Package a source distribution yourself from the latest Bazaar
-       developer source tree. For instructions on pulling the latest
-       source files, see Section 2.3.3, "Installing from the
-       Development Source Tree."
-
-   If you find something not working as expected, or you have
-   suggestions about ways to improve the current build process on
-   Windows, please send a message to the win32 mailing list. See
-   Section 1.6.1, "MySQL Mailing Lists."
-
-2.5.10.1. Building MySQL from Source Using CMake and Visual Studio
-
-   You can build MySQL on Windows by using a combination of cmake and
-   Microsoft Visual Studio .NET 2003 (7.1), Microsoft Visual Studio
-   2005 (8.0), Microsoft Visual Studio 2008 (9.0) or Microsoft Visual
-   C++ 2005 Express Edition. You must have the appropriate Microsoft
-   Platform SDK installed.
-
-Note
-
-   To compile from the source code on Windows you must use the
-   standard source distribution (for example, mysql-5.1.46.tar.gz).
-   You build from the same distribution as used to build MySQL on
-   Unix, Linux and other platforms. Do not use the Windows Source
-   distributions as they do not contain the necessary configuration
-   script and other files.
-
-   Follow this procedure to build MySQL:
-
-    1. If you are installing from a packaged source distribution,
-       create a work directory (for example, C:\workdir), and unpack
-       the source distribution there using WinZip or another Windows
-       tool that can read .zip files. This directory is the work
-       directory in the following instructions.
-
-Note
-       You must run the commands in the win directory from the
-       top-level source directory. Do not change into the win
-       directory, as the commands will not be executed correctly.
-
-    2. Start a command shell. If you have not configured the PATH and
-       other environment variables for all command shells, you may be
-       able to start a command shell from the Start Menu within the
-       Windows Visual Studio menu that contains the necessary
-       environment changes.
-
-    3. Within the command shell, navigate to the work directory and
-       run the following command:
-C:\workdir>win\configure.js options
-       If you have associated the .js file extension with an
-       application such as a text editor, then you may need to use
-       the following command to force configure.js to be executed as
-       a script:
-C:\workdir>cscript win\configure.js options
-       These options are available for configure.js:
-
-          + WITH_INNOBASE_STORAGE_ENGINE: Enable the InnoDB storage
-            engine.
-
-          + WITH_PARTITION_STORAGE_ENGINE: Enable user-defined
-            partitioning.
-
-          + WITH_ARCHIVE_STORAGE_ENGINE: Enable the ARCHIVE storage
-            engine.
-
-          + WITH_BLACKHOLE_STORAGE_ENGINE: Enable the BLACKHOLE
-            storage engine.
-
-          + WITH_EXAMPLE_STORAGE_ENGINE: Enable the EXAMPLE storage
-            engine.
-
-          + WITH_FEDERATED_STORAGE_ENGINE: Enable the FEDERATED
-            storage engine.
-
-          + WITH_NDBCLUSTER_STORAGE_ENGINE (experimental): Enable the
-            NDBCLUSTER storage engine in the MySQL server; cause
-            binaries for the MySQL Cluster management and data node,
-            management client, and other programs to be built.
-            This option is supported only in MySQL Cluster NDB 7.0
-            (NDBCLUSTER storage engine versions 6.4.0 and later)
-            using the MySQL Cluster sources. It cannot be used to
-            enable clustering support in other MySQL source trees or
-            distributions.
-
-          + MYSQL_SERVER_SUFFIX=suffix: Server suffix, default none.
-
-          + COMPILATION_COMMENT=comment: Server comment, default
-            "Source distribution".
-
-          + MYSQL_TCP_PORT=port: Server port, default 3306.
-
-          + DISABLE_GRANT_OPTIONS: Disables the --bootstrap,
-            --skip-grant-tables, and --init-file options for mysqld.
-            This option is available as of MySQL 5.1.15.
-       For example (type the command on one line):
-C:\workdir>win\configure.js WITH_INNOBASE_STORAGE_ENGINE
-             WITH_PARTITION_STORAGE_ENGINE MYSQL_SERVER_SUFFIX=-pro
-
-    4. From the work directory, execute the win\build-vs9.bat
-       (Windows Visual Studio 2008), win\build-vs8.bat (Windows
-       Visual Studio 2005), or win\build-vs71.bat (Windows Visual
-       Stidion 2003) script, depending on the version of Visual
-       Studio you have installed. The script invokes CMake, which
-       generates the mysql.sln solution file.
-       You can also use the corresponding 64-bit file (for example
-       win\build-vs8_x64.bat or win\build-vs9_x64.bat) to build the
-       64-bit version of MySQL. However, you cannot build the 64-bit
-       version with Visual Studio Express Edition. You must use
-       Visual Studio 2005 (8.0) or higher.
-
-    5. From the work directory, open the generated mysql.sln file
-       with Visual Studio and select the proper configuration using
-       the Configuration menu. The menu provides Debug, Release,
-       RelwithDebInfo, MinRelInfo options. Then select Solution >
-       Build to build the solution.
-       Remember the configuration that you use in this step. It is
-       important later when you run the test script because that
-       script needs to know which configuration you used.
-
-    6. Test the server. The server built using the preceding
-       instructions expects that the MySQL base directory and data
-       directory are C:\mysql and C:\mysql\data by default. If you
-       want to test your server using the source tree root directory
-       and its data directory as the base directory and data
-       directory, you need to tell the server their path names. You
-       can either do this on the command line with the --basedir and
-       --datadir options, or by placing appropriate options in an
-       option file. (See Section 4.2.3.3, "Using Option Files.") If
-       you have an existing data directory elsewhere that you want to
-       use, you can specify its path name instead.
-       When the server is running in standalone fashion or as a
-       service based on your configuration, try to connect to it from
-       the mysql interactive command-line utility.
-       You can also run the standard test script, mysql-test-run.pl.
-       This script is written in Perl, so you'll need either Cygwin
-       or ActiveState Perl to run it. You may also need to install
-       the modules required by the script. To run the test script,
-       change location into the mysql-test directory under the work
-       directory, set the MTR_VS_CONFIG environment variable to the
-       configuration you selected earlier (or use the --vs-config
-       option), and invoke mysql-test-run.pl. For example (using
-       Cygwin and the bash shell):
-shell> cd mysql-test
-shell> export MTR_VS_CONFIG=debug
-shell> ./mysql-test-run.pl --force --timer
-shell> ./mysql-test-run.pl --force --timer --ps-protocol
-
-   When you are satisfied that the programs you have built are
-   working correctly, stop the server. Now you can install the
-   distribution. One way to do this is to use the make_win_bin_dist
-   script in the scripts directory of the MySQL source distribution
-   (see Section 4.4.2, "make_win_bin_dist --- Package MySQL
-   Distribution as ZIP Archive"). This is a shell script, so you must
-   have Cygwin installed if you want to use it. It creates a Zip
-   archive of the built executables and support files that you can
-   unpack in the location at which you want to install MySQL.
-
-   It is also possible to install MySQL by copying directories and
-   files directly:
-
-    1. Create the directories where you want to install MySQL. For
-       example, to install into C:\mysql, use these commands:
-C:\> mkdir C:\mysql
-C:\> mkdir C:\mysql\bin
-C:\> mkdir C:\mysql\data
-C:\> mkdir C:\mysql\share
-C:\> mkdir C:\mysql\scripts
-       If you want to compile other clients and link them to MySQL,
-       you should also create several additional directories:
-C:\> mkdir C:\mysql\include
-C:\> mkdir C:\mysql\lib
-C:\> mkdir C:\mysql\lib\debug
-C:\> mkdir C:\mysql\lib\opt
-       If you want to benchmark MySQL, create this directory:
-C:\> mkdir C:\mysql\sql-bench
-       Benchmarking requires Perl support. See Section 2.15, "Perl
-       Installation Notes."
-
-    2. From the work directory, copy into the C:\mysql directory the
-       following files and directories:
-C:\> cd \workdir
-C:\workdir> mkdir C:\mysql
-C:\workdir> mkdir C:\mysql\bin
-C:\workdir> copy client\Release\*.exe C:\mysql\bin
-C:\workdir> copy sql\Release\mysqld.exe C:\mysql\bin\mysqld.exe
-C:\workdir> xcopy scripts\*.* C:\mysql\scripts /E
-C:\workdir> xcopy share\*.* C:\mysql\share /E
-       If you want to compile other clients and link them to MySQL,
-       you should also copy several libraries and header files:
-C:\workdir> copy lib\Release\mysqlclient.lib C:\mysql\lib\debug
-C:\workdir> copy lib\Release\libmysql.* C:\mysql\lib\debug
-C:\workdir> copy lib\Release\zlib.* C:\mysql\lib\debug
-C:\workdir> copy lib\Release\mysqlclient.lib C:\mysql\lib\opt
-C:\workdir> copy lib\Release\libmysql.* C:\mysql\lib\opt
-C:\workdir> copy lib\Release\zlib.* C:\mysql\lib\opt
-C:\workdir> copy include\*.h C:\mysql\include
-C:\workdir> copy libmysql\libmysql.def C:\mysql\include
-
-Note
-       If you have compiled a Debug, rather than Release solution,
-       you can replace Release with Debug in the source file names
-       shown above.
-       If you want to benchmark MySQL, you should also do this:
-C:\workdir> xcopy sql-bench\*.* C:\mysql\bench /E
-
-   After installation, set up and start the server in the same way as
-   for binary Windows distributions. This includes creating the
-   system tables by running mysql_install_db. For more information,
-   see Section 2.5, "Installing MySQL on Windows."

+Putting testcases here
+~~~~~~~~~~~~~~~~~~~~~~
+
+When you work on re-verifying or re-classifying a bug (not fixing it),
+it's a good idea to put the mtr-parsable '.test' testcase here.
+Benefits:
+1) tests downloaded from the bugs db are sometimes close to
+mtr-parsable but not completely (for example if they contain
+/* comment */); when you re-verify or re-classify you run the test so
+may have to make it mtr-parsable; if you then put it in this suite,
+the developer who will work on this bug in a few weeks or months will
+not have to re-do the same download&fix, she/he can instead reuse your
+work.
+2) Others can see how their own work influences many unsolved
+bugs, by running this suite. If they find that they fix a bug in this
+suite, we won't later wonder "how come this bug doesn't happen
+anymore, what fixed it?".
+3) One can also run this suite with certain switches to see how they
+influence unsolved bugs:
+./mtr --suite=optimizer_unfixed_bugs \
+--mysqld=--optimizer_switch="firstmatch=off"
+
+Adding tests to this suite
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+One test file per bug, named bugNNNNN.test.
+Put the correct (not current and buggy) result file in r/, so that "[ pass ]"
+in mtr will mean that a bug looks like fixed.
+When you have fixed a bug, remove files from this suite.
+t/bug45219.test is an example.

+Binlog checksum testing
+=======================
+
+1. How it works.
+The script copies a <suite> to directory <suite>_checksum, 
+collects test case names for t/ directory (except tests from
+disabled def), randomly choose 90% of tests and add them 
+to disabled.def.
+It means that mtr will run only 10% of random tests from each 
+suite.
+At end the script run mtr:
+./mysql-test-run.pl --suite=aaa_checksum,bbb_checksum \
+    --mysqld=--binlog-checksum=CRC32 arg1 ... argN
+
+aaa,bbb 	- suite names from --suite option
+arg1,argN	- other command-line arguments of checksum.pl
+
+2. The options:
+
+--suite=suite1,suite2.  Mandatory option. The list of suites for 
+    binlog checksum testing.
+
+--percent=N, where N is 1..99. Percent of running tests.

+#
+#2.1 Please add a case when two subqueries  are used in the where clause
+#(or in select) of a 2-way join.
+#The first subquery is accessed after the first table, while the second
+#is accessed after the second table.
+#
+#2.2. Please add a test case when one non-correlated subquery contains
+#another non-correlated subquery.
+#Consider 4 subcases:
+#   both subqueries are materialized
+#   IN_EXIST transformations are applied to both subqueries
+#   outer subquery is materialized while the inner subquery  is not
+#(IN_EXIST transformation is applied to it)
+#   inner subqyery is materialized while the outer subquery  is not (
+#IN_EXIST transformation is applied to it)

+    first unlock the file and then lock it shared. A waiting exclusive
+    lock could step in here. For reasons described in Bug#38133 and

+    INSERT...SELECT) and in the review thread at
+    http://lists.mysql.com/commits/60721 it seems to be the better
+    option than not to unlock here.
+    If one day someone notices a way how to do file lock type changes
+    on Windows without unlocking before taking the new lock, please
+    change this code accordingly to fix the race condition.

+  The purpose of this file is to provide implementation of file IO routines on

+  functionality.
+
+  Compared to Windows CRT, this one 
+  - does not have the same file descriptor 
+  limitation (default is 16384 and can  be increased further, whereas CRT poses
+  a hard limit of 2048 file descriptors)
+  - the file operations are not serialized
+  - positional IO pread/pwrite is ported here.
+  - no text mode for files, all IO is "binary"
+
+  Naming convention:
+  All routines are prefixed with my_win_, e.g Posix open() is implemented with 
+  my_win_open()
+
+  Implemented are
+  - POSIX routines(e.g open, read, lseek ...)
+  - Some ANSI C stream routines (fopen, fdopen, fileno, fclose)
+  - Windows CRT equvalients (my_get_osfhandle, open_osfhandle)
+
+  Worth to note:
+  - File descriptors used here are located in a range that is not compatible 
+  with CRT on purpose. Attempt to use a file descriptor from Windows CRT library
+  range in my_win_* function will be punished with DBUG_ASSERT()
+
+  - File streams (FILE *) are actually from the C runtime. The routines provided
+  here are useful only in scernarios that use low-level IO with my_win_fileno()

-  An optimisation of _downheap suggested in Exercise 7.51 in "Data
-  Structures & Algorithms in C++" by Mark Allen Weiss, Second Edition

+  The queue can optionally store the position in queue in the element

+  in O(1) time.
+
+  Optimisation of _downheap() and queue_fix() is inspired by code done

+About HandlerSocket
+
+HandlerSocket is a NoSQL plugin for MySQL. It works as a daemon inside the
+mysqld process, accept tcp connections, and execute requests from clients.
+HandlerSocket does not support SQL queries. Instead, it supports simple CRUD
+operations on tables.
+
+Because of the following reasons, HandlerSocket is much faster than the
+mysqld/libmysql pair in some circumstances:
+
+  - HandlerSocket manipulates data without parsing SQL, which causes less
+    CPU usage.
+  - HandlerSocket reads many requests from clients and executes their
+    requests in bulk, which causes less CPU and disk usage.
+  - HandlerSocket client/server protocol is more compact than the 
+    mysql/libmysql pair, which causes less network usage.
+
+The current version of HandlerSocket only works with GNU/Linux. The source
+archive of HandlerSocket includes a C++ and a Perl client libraries.
+Here is a list of client libraries for other languages:
+
+  - PHP
+    http://openpear.org/package/Net_HandlerSocket
+    http://github.com/tz-lom/HSPHP
+    http://code.google.com/p/php-handlersocket/
+  - Java
+    http://code.google.com/p/hs4j/
+    http://code.google.com/p/handlersocketforjava/
+  - Python
+    http://pypi.python.org/pypi/python-handler-socket
+    https://code.launchpad.net/~songofacandy/+junk/pyhandlersocket
+  - Ruby
+    https://github.com/winebarrel/ruby-handlersocket
+    https://github.com/miyucy/handlersocket
+  - JavaScript

+  - Scala

+About HandlerSocket
+
+HandlerSocket is a NoSQL plugin for MySQL. It works as a daemon inside the
+mysqld process, accept tcp connections, and execute requests from clients.
+HandlerSocket does not support SQL queries. Instead, it supports simple CRUD
+operations on tables.
+
+Because of the following reasons, HandlerSocket is much faster than the
+mysqld/libmysql pair in some circumstances:
+
+  - HandlerSocket manipulates data without parsing SQL, which causes less
+    CPU usage.
+  - HandlerSocket reads many requests from clients and executes their
+    requests in bulk, which causes less CPU and disk usage.
+  - HandlerSocket client/server protocol is more compact than the 
+    mysql/libmysql pair, which causes less network usage.
+
+The current version of HandlerSocket only works with GNU/Linux. The source
+archive of HandlerSocket includes a C++ and a Perl client libraries.
+Here is a list of other language bindings:
+
+  - PHP
+    http://openpear.org/package/Net_HandlerSocket
+    http://github.com/tz-lom/HSPHP
+    http://code.google.com/p/php-handlersocket/
+  - Java

+1. Building Handlersocket
+
+ Handlersocket mainly consists of libhsclient, handlersocket, and C++/Perl clients. libhsclient is a common library shared from both client and server(plugin). handlersocket is a MySQL daemon plugin.
+ To build Handlersocket, you need both MySQL source code and MySQL binary. It is not required to pre-build MySQL source code, but source itself is needed because Handlersocket depends on MySQL header files that only MySQL source distribution contains. MySQL binary is just a normal MySQL binary distribution. You can use official MySQL binaries provided by Oracle.
+ Since Handlersocket uses daemon plugin interface supported from MySQL 5.1,
+MySQL 5.1 or higher version is required.
+ Please make sure that you use identical MySQL version between MySQL source
+and MySQL binary. Otherwise you might encounter serious problems (i.e. server
+crash, etc). 
+ Here are steps to build Handlersocket.
+
+* Get MySQL source code
+
+* Get MySQL binary
+
+* Build Handlersocket
+  $ ./autogen.sh
+  $ ./configure --with-mysql-source=/work/mysql-5.1.50 --with-mysql-bindir=/work/mysql-5.1.50-linux-x86_64-glibc23/bin  --with-mysql-plugindir=/work/mysql-5.1.50-linux-x86_64-glibc23/lib/plugin
+
+ --with-mysql-source refers to the top of MySQL source directory,
+--with-mysql-bindir refers to where MySQL binary executables (i.e.
+mysql_config) are located, and --with-mysql-plugindir refers to a plugin
+directory where plugin libraries (*.so) are installed.  
+
+  $ make
+  $ sudo make install
+
+ Both libhsclient and the handlersocket plugin will be installed.
+
+ 
+2. Using Handlersocket
+
+Append configuration options for handlersocket to my.cnf.
+
+  [mysqld]
+  loose_handlersocket_port = 9998
+    # the port number to bind to (for read requests)
+  loose_handlersocket_port_wr = 9999
+    # the port number to bind to (for write requests)
+  loose_handlersocket_threads = 16
+    # the number of worker threads (for read requests)
+  loose_handlersocket_threads_wr = 1
+    # the number of worker threads (for write requests)
+  open_files_limit = 65535
+    # to allow handlersocket accept many concurrent
+    # connections, make open_files_limit as large as
+    # possible.
+
+Log in to mysql as root, and execute the following query.
+
+  mysql> install plugin handlersocket soname 'handlersocket.so';
+
+If handlersocket.so is successfully installed, it starts
+accepting connections on port 9998 and 9999. Running
+'show processlist' should show handlersocket worker threads.
+
+-----------------------------------------------------------------
+On the client side, you need to install libhsclient for c++ apps
+and perl-Net-HandlerSocket for perl apps. They do not require
+MySQL to compile.
+
+  $ ./autogen.sh
+  $ ./configure --disable-handlersocket-server
+  $ make
+  $ sudo make install
+  $ cd perl-Net-HandlerSocket
+  $ perl Makefile.PL
+  $ make
+  $ sudo make install
+
+-----------------------------------------------------------------
+Alternatively, you can use the rpm installation. If your OS
+supports rpms, you can use the following commands to build and
+install handlersocket rpm packages.
+
+(Server side, installs HandlerSocket plugin)
+  $ ./autogen.sh
+  $ ./configure --with-mysql-source=/work/mysql-5.1.50 --with-mysql-bindir=/work/mysql-5.1.50-linux-x86_64-glibc23/bin  --with-mysql-plugindir=/work/mysql-5.1.50-linux-x86_64-glibc23/lib/plugin
+  $ make rpm_cli
+  $ sudo rpm -U dist/RPMS/*/libhsclient*.rpm
+  $ make rpm_c
+  $ sudo rpm -U dist/RPMS/*/handlersocket*.rpm
+
+(Client side, installs client libraries)
+  $ ./autogen.sh
+  $ ./configure --disable-handlersocket-server
+  $ make rpm_cli
+  $ sudo rpm -U dist/RPMS/*/libhsclient*.rpm
+  $ make rpm_perl
+  $ sudo rpm -U dist/RPMS/*/perl-Net-HandlerSocket*.rpm
+

+-----------------------------------------------------------------
+To open a connection to the handlersocket plugin, you need to
+create a Net::HandlerSocket object.
+
+  use Net::HandlerSocket;
+  my $args = { host => 'localhost', port => 9998 };
+  my $hs = new Net::HandlerSocket($args);
+
+-----------------------------------------------------------------
+Before executing table operations, you need to open an index to
+work with.
+
+  my $err = $hs->open_index(3, 'database1', 'table1', 'PRIMARY',
+    'f1,f2');
+  die $hs->get_error() if $res->[0] != 0;
+
+The first argument for open_index is an integer value which is
+used to identify an open table, which is only valid within the
+same Net::HandlerSocket object. The 4th argument is the name of
+index to open. If 'PRIMARY' is specified, the primary index is
+open. The 5th argument is a comma-separated list of column names.
+
+-----------------------------------------------------------------
+To read a record from a table using an index, call the
+execute_single method.
+
+  my $res = $hs->execute_single(3, '=', [ 'foo' ], 1, 0);
+  die $hs->get_error() if $res->[0] != 0;
+  shift(@$res);
+
+The first argument must be an integer which has specified as the
+first argument for open_index on the same Net::HandlerSocket
+object. The second argument specifies the search operation. The
+current version of handlersocket supports '=', '>=', '<=', '>',
+and '<'. The 3rd argument specifies the key to find, which must
+an arrayref whose length is equal to or smaller than the number
+of key columns of the index. The 4th and the 5th arguments
+specify the maximum number of records to be retrieved, and the
+number of records skipped before retrieving records. The columns
+to be retrieved are specified by the 5th argument for the
+corresponding open_index call.
+
+The execute_single method always returns an arrayref. The first
+element is the error code, which is 0 when no error is occured.
+The remaining are the field values. If more than one record is
+returned, it is flatten to an 1-dimensional array. For example,
+when 5 records that have 3 columns are returned, you can retrieve
+values using the following code.
+
+  die $hs->get_error() if $res->[0] != 0;
+  shift(@$res);
+  for (my $row = 0; $row < 5; ++$row) {
+    for (my $col = 0; $col < 3; ++$col) {
+      my $value = $res->[$row * 5 + $col];
+      # ...
+    }
+  }
+
+-----------------------------------------------------------------
+To update or delete records, you need to specify more arguments
+for the execute_single method. Note that the Net::HandlerSocket
+object must be connected to a handlersocket worker for write
+operations, which is port 9999 by default.
+(For safety, the port 9998 only allows read operations, and the
+port 9999 allows write operations also. The port 9999 allows
+read operations too, but slower than 9998 because of record
+locking etc.. Port numbers can be changed using the
+'handlersocket_port' and the 'handlersocket_port_wr'
+configuration options of mysqld.)
+
+  my $args = { host => 'localhost', port => 9999 };
+  my $hs = new Net::HandlerSocket($args);
+
+  my $res = $hs->execute_single(3, '=', [ 'bar' ], 1, 0, 'U',
+    [ 'fubar', 'hoge' ]);
+  die $hs->get_error() if $res->[0] != 0;
+  my $num_updated_rows = $res->[1];
+
+  my $res = $hs->execute_single(3, '=', [ 'baz' ], 1, 0, 'D');
+  die $hs->get_error() if $res->[0] != 0;
+  my $num_deleted_rows = $res->[1];
+
+The 6th argument for execute_single specifies the modification
+operation. The current version supports 'U' and 'D'. For the 'U'
+operation, the 7th argument specifies the new value for the row.
+The columns to be modified are specified by the 5th argument for
+the corresponding open_index call. For the 'D' operation, the
+7th argument can be omitted.
+
+-----------------------------------------------------------------
+The execute_single method can be used for inserting records also.
+
+  my $res = $hs->execute_single(3, '+', [ 'foo', 'bar', 'baz' ]);
+  die $hs->get_error() if $res->[0] != 0;
+  my $num_inserted_rows = $res->[1];
+
+The 3rd argument must be an arrayref whose elements correspond to
+the 5th argument for the corresponding open_index call. If there
+is a column which is not appeared in the 5th argument for the
+open_index, the default value for the column is set.
+
+-----------------------------------------------------------------
+Multiple operations can be executed in a single call. Executing
+multiple operations in a single call is much faster than
+executing them separatedly. 
+
+  my $rarr = $hs->execute_multi([
+    [ 0, '>=', [ 'foo' ], 5, 0 ],
+    [ 2, '=', [ 'bar' ], 1, 0 ],
+    [ 4, '<', [ 'baz' ], 10, 5 ],
+  ]);
+  for my $res (@$rarr) {
+    die $hs->get_error() if $res->[0] != 0;
+    shift(@$res);
+    # ...
+  }
+
+-----------------------------------------------------------------
+When an error is occured, the first element of the returned
+arrayref becomes a non-zero value. A negative value indicates
+that an I/O error is occured and the Net::HandlerSocket object
+should be disposed. A positive value means that the connection is
+still active and the Net::HandlerSocket object can be reused
+later.

+The HandlerSocket protocol
+
+----------------------------------------------------------------------------
+Basic syntax
+
+- The HandlerSocket protocol is line-based. Each line ends with LF(0x0a).
+- Each line consists a concatenation of tokens separated by HT(0x09).
+- A token is either NULL or an encoded string. Note that you need to
+  distinguish NULL from an empty string, as most DBMs does so.
+- NULL is expressed as a single NUL(0x00).
+- An encoded string is a string with the following encoding rules.
+  	- Characters in the range [0x10 - 0xff] are encoded as itselves.
+	- A character in the range [0x00 - 0x0f] is prefixed by 0x01 and
+	  shifted by 0x40. For example, 0x03 is encoded as 0x01 0x43.
+- Note that a string can be empty. A continuation of 0x09 0x09 means that
+  there is an empty string between them. A continuation of 0x09 0x0a means
+  that there is an empty string at the end of the line.
+
+----------------------------------------------------------------------------
+Request and Response
+
+- The HandlerSocket protocol is a simple request/response protocol. After a
+  connection is established, the client side sends a request, and then the
+  server side sends a response.
+- A request/response consists of a single line.
+- Requests can be pipelined; That is, you can send multiple requests (ie.
+  lines) at one time, and receive responses for them at one time.
+
+----------------------------------------------------------------------------
+'open_index' request
+
+The 'open_index' request has the following syntax.
+
+    P <indexid> <dbname> <tablename> <indexname> <columns> [<fcolumns>]
+
+- <indexid> is a number in decimal.
+- <dbname>, <tablename>, and <indexname> are strings. To open the primary
+  key, use PRIMARY as <indexname>.
+- <columns> is a comma-separated list of column names.
+- <fcolumns> is a comma-separated list of column names. This parameter is
+  optional.
+
+Once an 'open_index' request is issued, the HandlerSocket plugin opens the
+specified index and keep it open until the client connection is closed. Each
+open index is identified by <indexid>. If <indexid> is already open, the old
+open index is closed. You can open the same combination of <dbname>
+<tablename> <indexname> multple times, possibly with different <columns>.
+For efficiency, keep <indexid> small as far as possible.
+
+----------------------------------------------------------------------------
+Getting data
+
+The 'find' request has the following syntax.
+ 
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...]
+
+LIM is a sequence of the following parameters.
+
+    <limit> <offset>
+
+IN is a sequence of the following parameters.
+    
+    @ <icol> <ivlen> <iv1> ... <ivn>
+
+FILETER is a sequence of the following parameters.
+
+    <ftyp> <fop> <fcol> <fval>
+
+- <indexid> is a number. This number must be an <indexid> specified by a
+  'open_index' request executed previously on the same connection.
+- <op> specifies the comparison operation to use. The current version of
+  HandlerSocket supports '=', '>', '>=', '<', and '<='.
+- <vlen> indicates the length of the trailing parameters <v1> ... <vn>. This
+  must be smaller than or equal to the number of index columns specified by
+  the <columns> parameter of the corresponding 'open_index' request.
+- <v1> ... <vn> specify the index column values to fetch.
+- LIM is optional. <limit> and <offset> are numbers. When omitted, it works
+  as if 1 and 0 are specified. These parameter works like LIMIT of SQL.
+  These values don't include the number of records skipped by a filter.
+- IN is optional. It works like WHERE ... IN syntax of SQL. <icol> must be
+  smaller than or equal to the number of index columns specified by the
+  <columns> parameter of the corresponding 'open_index' request. If IN is
+  specified in a find request, the <icol>-th parameter value of <v1> ...
+  <vn> is ignored.
+  smaller than or equal to the number of index columns specified by the
+- FILTERs are optional. A FILTER specifies a filter. <ftyp> is either 'F'
+  (filter) or 'W' (while). <fop> specifies the comparison operation to use.
+  <fcol> must be smaller than or equal to the number of columns specified by
+  the <fcolumns> parameter of the corresponding 'open_index' request.
+  Multiple filters can be specified, and work as the logical AND of them.
+  The difference of 'F' and 'W' is that, when a record does not meet the
+  specified condition, 'F' simply skips the record, and 'W' stops the loop.
+
+----------------------------------------------------------------------------
+Updating/Deleting data
+
+The 'find_modify' request has the following syntax.
+
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...] MOD
+
+MOD is a sequence of the following parameters.
+
+    <mop> <m1> ... <mk>
+
+- <mop> is 'U' (update), '+' (increment), '-' (decrement), 'D' (delete),
+  'U?', '+?', '-?', or 'D?'. If the '?' suffix is specified, it returns
+  the contents of the records before modification (as if it's a 'find'
+  request), instead of the number of modified records.
+- <m1> ... <mk> specifies the column values to set. The length of <m1> ...
+  <mk> must be smaller than or equal to the length of <columns> specified by
+  the corresponding 'open_index' request. If <mop> is 'D', these parameters
+  are ignored. If <mop> is '+' or '-', values must be numeric. If <mop> is
+  '-' and it attempts to change column values from negative to positive or
+  positive to negative, it is not modified.
+
+----------------------------------------------------------------------------
+Inserting data
+
+The 'insert' request has the following syntax.
+
+    <indexid> + <vlen> <v1> ... <vn>
+
+- <vlen> indicates the length of the trailing parameters <v1> ... <vn>. This
+  must be smaller than or equal to the length of <columns> specified by the
+  corresponding 'open_index' request.
+- <v1> ... <vn> specify the column values to set. For columns not in
+  <columns>, the default values for each column are set.
+
+----------------------------------------------------------------------------
+Authentication
+
+The 'auth' request has the following syntax.
+
+    A <atyp> <akey>
+
+- <atyp> must be '1'
+- An 'auth' request succeeds iff <akey> is the correct secret specified by
+  the 'handlersocket_plain_secret' or 'handlersocket_plain_secret_rw'.
+- If an authentication is enabled for a listener, any other requests on a
+  connection fail before an 'auth' request succeeded on the connection.
+
+----------------------------------------------------------------------------
+Response syntax
+
+HandlerSocket returns a response of the following syntax for each request.
+
+    <errorcode> <numcolumns> <r1> ... <rn>
+
+- <errorcode> indicates whether the request has successfully executed or not.
+  '0' means success. Non-zero means an error.
+- <numcolumns> indicates the number of columns of the result set.
+- <r1> ... <rn> is the result set. The length of <r1> ... <rn> is always a
+  multiple of <numcolumns>. It is possible that <r1> ... <rn> is empty.
+
+If <errorcode> is non-zero, <numcolumns> is always 1 and <r1> indicates a
+human-readable error message, though sometimes <r1> is not provided.
+
+----------------------------------------------------------------------------
+Response for 'open_index'
+
+If 'open_index' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+    0 1
+
+----------------------------------------------------------------------------
+Response for 'find'
+
+If 'find' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+   0 <numcolumns> <r1> ... <rn>
+
+- <numcolumns> always equals to the length of <columns> of the corresponding
+  'open_index' request.
+- <r1> ... <rn> is the result set. If N rows are found, the length of <r1>
+  ... <rn> becomes ( <numcolumns> * N ).
+
+----------------------------------------------------------------------------
+Response for 'find_modify'
+
+If 'find_modify' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+   0 1 <nummod>
+
+- <nummod> is the number of modified rows.
+
+----------------------------------------------------------------------------
+Response for 'insert'
+
+If 'insert' is succeeded, HanderSocket returns a line of the following
+syntax.
+
+   0 1

+HandlerSocket version 0.01
+==========================
+
+The README is used to introduce the module and provide instructions on
+how to install the module, any machine dependencies it may have (for
+example C compilers and installed libraries) and any other information
+that should be provided before the module is installed.
+
+A README file is required for CPAN modules since CPAN extracts the
+README file from a module distribution so that people browsing the
+archive can use it get an idea of the modules uses. It is usually a
+good idea to provide version information here so that people can
+decide whether fixes for the module are worth downloading.
+
+INSTALLATION
+
+To install this module type the following:
+
+   perl Makefile.PL
+   make
+   make test
+   make install

+
+  --patch=file                write one patch file with changes
+  --copy=suffix               write changed copies with suffix
+  --diff=program              use diff program and options
+
+  --compat-version=version    provide compatibility with Perl version
+  --cplusplus                 accept C++ comments
+
+  --quiet                     don't output anything except fatal errors

+
+=head1 COMPATIBILITY
+
+This version of F<ppport.h> is designed to support operation with Perl
+installations back to 5.003, and has been tested up to 5.10.0.
+
+=head1 OPTIONS
+
+=head2 --help
+
+Display a brief usage summary.
+
+=head2 --version
+
+Display the version of F<ppport.h>.
+
+=head2 --patch=I<file>
+
+If this option is given, a single patch file will be created if
+any changes are suggested. This requires a working diff program
+to be installed on your system.
+
+=head2 --copy=I<suffix>
+
+If this option is given, a copy of each file will be saved with
+the given suffix that contains the suggested changes. This does
+not require any external programs. Note that this does not
+automagially add a dot between the original filename and the
+suffix. If you want the dot, you have to include it in the option
+argument.
+
+If neither C<--patch> or C<--copy> are given, the default is to
+simply print the diffs for each file. This requires either
+C<Text::Diff> or a C<diff> program to be installed.
+
+=head2 --diff=I<program>
+
+Manually set the diff program and options to use. The default
+is to use C<Text::Diff>, when installed, and output unified
+context diffs.
+
+=head2 --compat-version=I<version>
+
+Tell F<ppport.h> to check for compatibility with the given
+Perl version. The default is to check for compatibility with Perl
+version 5.003. You can use this option to reduce the output
+of F<ppport.h> if you intend to be backward compatible only
+down to a certain Perl version.
+
+=head2 --cplusplus
+
+Usually, F<ppport.h> will detect C++ style comments and
+replace them with C style comments for portability reasons.
+Using this option instructs F<ppport.h> to leave C++
+comments untouched.
+
+=head2 --quiet
+
+Be quiet. Don't print anything except fatal errors.
+
+=head2 --nodiag
+
+Don't output any diagnostic messages. Only portability
+alerts will be printed.
+
+=head2 --nohints
+
+Don't output any hints. Hints often contain useful portability
+notes. Warnings will still be displayed.
+
+=head2 --nochanges
+
+Don't suggest any changes. Only give diagnostic output and hints
+unless these are also deactivated.
+
+=head2 --nofilter
+
+Don't filter the list of input files. By default, files not looking
+like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped.
+
+=head2 --strip
+
+Strip all script and documentation functionality from F<ppport.h>.
+This reduces the size of F<ppport.h> dramatically and may be useful
+if you want to include F<ppport.h> in smaller modules without
+increasing their distribution size too much.
+
+The stripped F<ppport.h> will have a C<--unstrip> option that allows
+you to undo the stripping, but only if an appropriate C<Devel::PPPort>
+module is installed.
+
+=head2 --list-provided
+
+Lists the API elements for which compatibility is provided by
+F<ppport.h>. Also lists if it must be explicitly requested,
+if it has dependencies, and if there are hints or warnings for it.
+
+=head2 --list-unsupported
+
+Lists the API elements that are known not to be supported by
+F<ppport.h> and below which version of Perl they probably
+won't be available or work.
+
+=head2 --api-info=I<name>
+
+Show portability information for API elements matching I<name>.
+If I<name> is surrounded by slashes, it is interpreted as a regular
+expression.
+
+=head1 DESCRIPTION
+
+In order for a Perl extension (XS) module to be as portable as possible
+across differing versions of Perl itself, certain steps need to be taken.
+
+=over 4
+
+=item *
+
+Including this header is the first major one. This alone will give you
+access to a large part of the Perl API that hasn't been available in
+earlier Perl releases. Use
+
+    perl ppport.h --list-provided
+
+to see which API elements are provided by ppport.h.
+
+=item *
+
+You should avoid using deprecated parts of the API. For example, using
+global Perl variables without the C<PL_> prefix is deprecated. Also,
+some API functions used to have a C<perl_> prefix. Using this form is
+also deprecated. You can safely use the supported API, as F<ppport.h>
+will provide wrappers for older Perl versions.
+
+=item *
+
+If you use one of a few functions or variables that were not present in
+earlier versions of Perl, and that can't be provided using a macro, you
+have to explicitly request support for these functions by adding one or
+more C<#define>s in your source code before the inclusion of F<ppport.h>.
+
+These functions or variables will be marked C<explicit> in the list shown
+by C<--list-provided>.
+
+Depending on whether you module has a single or multiple files that
+use such functions or variables, you want either C<static> or global
+variants.
+
+For a C<static> function or variable (used only in a single source
+file), use:
+
+    #define NEED_function
+    #define NEED_variable
+
+For a global function or variable (used in multiple source files),
+use:
+
+    #define NEED_function_GLOBAL
+    #define NEED_variable_GLOBAL
+
+Note that you mustn't have more than one global request for the
+same function or variable in your project.

+
+To avoid namespace conflicts, you can change the namespace of the
+explicitly exported functions / variables using the C<DPPP_NAMESPACE>
+macro. Just C<#define> the macro before including C<ppport.h>:
+
+    #define DPPP_NAMESPACE MyOwnNamespace_
+    #include "ppport.h"
+
+The default namespace is C<DPPP_>.
+
+=back
+
+The good thing is that most of the above can be checked by running
+F<ppport.h> on your source code. See the next section for
+details.
+
+=head1 EXAMPLES
+
+To verify whether F<ppport.h> is needed for your module, whether you
+should make any changes to your code, and whether any special defines
+should be used, F<ppport.h> can be run as a Perl script to check your
+source code. Simply say:
+
+    perl ppport.h
+
+The result will usually be a list of patches suggesting changes
+that should at least be acceptable, if not necessarily the most
+efficient solution, or a fix for all possible problems.
+
+If you know that your XS module uses features only available in
+newer Perl releases, if you're aware that it uses C++ comments,
+and if you want all suggestions as a single patch file, you could
+use something like this:
+
+    perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
+
+If you only want your code to be scanned without any suggestions
+for changes, use:
+
+    perl ppport.h --nochanges
+
+You can specify a different C<diff> program or options, using
+the C<--diff> option:
+
+    perl ppport.h --diff='diff -C 10'
+
+This would output context diffs with 10 lines of context.
+
+If you want to create patched copies of your files instead, use:
+
+    perl ppport.h --copy=.new
+
+To display portability information for the C<newSVpvn> function,
+use:
+
+    perl ppport.h --api-info=newSVpvn
+
+Since the argument to C<--api-info> can be a regular expression,
+you can use
+
+    perl ppport.h --api-info=/_nomg$/
+
+to display portability information for all C<_nomg> functions or
+
+    perl ppport.h --api-info=/./
+
+to display information for all known API elements.
+
+=head1 BUGS

+=head1 SYNOPSIS
+
+B<mytop> [options]
+
+=head1 AVAILABILITY
+
+Base version from B<http://www.mysqlfanboy.com/mytop>.
+
+This version comes as part of the B<MariaDB> distribution. See B<http://mariadb.org/>.
+
+And older (the original) version B<mytop> is available from
+http://jeremy.zawodny.com/mysql/mytop/ it B<might> also be on CPAN as
+well.
+
+=head1 REQUIREMENTS
+
+In order for B<mytop> to function properly, you must have the
+following:
+
+  * Perl 5.005 or newer
+  * Getopt::Long
+  * DBI and DBD::mysql
+  * Term::ReadKey from CPAN
+
+Most systems are likely to have all of those installed--except for
+Term::ReadKey. You will need to pick that up from the CPAN. You can
+pick up Term::ReadKey here:
+
+    http://search.cpan.org/search?dist=TermReadKey
+
+And you obviously need access to a MySQL server (version 3.22.x or
+3.23.x) with the necessary security to run the I<SHOW PROCESSLIST> and
+I<SHOW STATUS> commands.
+
+If you are a Windows user, using ActiveState's Perl, you can use PPM
+(the Perl Package Manager) to install the MySQL and Term::ReadKey
+modules.
+
+=head2 Optional Color Support
+
+In additon, if you want a color B<mytop> (recommended), install
+Term::ANSIColor from the CPAN:
+
+    http://search.cpan.org/search?dist=ANSIColor
+
+Once you do, B<mytop> will automatically use it. However, color is not
+yet working on Windows. Patches welcome. :-)
+
+=head2 Optional Hi-Res Timing
+
+If you want B<mytop> to provide more accurate real-time
+queries-per-second statistics, install the Time::HiRes module from
+CPAN.  B<mytop> will automatically notice that you have it and use it
+rather than the standard timing mechanism.
+
+=head2 Platforms
+
+B<mytop> is known to work on:
+
+  * Linux (2.2.x, 2.4.x)
+  * FreeBSD (2.2, 3.x, 4.x)
+  * Mac OS X
+  * BSDI 4.x
+  * Solaris 2.x
+  * Windows NT 4.x (ActivePerl)
+
+If you find that it works on another platform, please let me
+know. Given that it is all Perl code, I expect it to be rather
+portable to Unix and Unix-like systems. Heck, it I<might> even work on
+Win32 systems.
+
+=head1 DESCRIPTION
+
+Help is always welcome in improving this software. Feel free to
+contact the author (see L<"AUTHOR"> below) with bug reports, fixes,
+suggestions, and comments. Additionally L<"BUGS"> will provide a list
+of things this software is not able to do yet.
+
+Having said that, here are the details on how it works and what you can
+do with it.
+
+=head2 The Basics
+
+B<mytop> was inspired by the system monitoring tool B<top>. I
+routinely use B<top> on Linux, FreeBSD, and Solaris. You are likely to
+notice features from each of them here.
+
+B<mytop> will connect to a MySQL server and periodically run the
+I<SHOW PROCESSLIST> and I<SHOW STATUS> commands and attempt to
+summarize the information from them in a useful format.
+
+=head2 The Display
+
+The B<mytop> display screen is really broken into two parts. The top 4
+lines (header) contain summary information about your MySQL
+server. For example, you might see something like:
+
+MySQL on localhost (4.0.13-log)                        up 1+11:13:00 [23:29:11]
+ Queries: 19.3M  qps:  160 Slow:     1.0         Se/In/Up/De(%):    00/80/03/17
+             qps now:  219 Slow qps: 0.0  Threads:    1 (   1/  16) 00/74/00/25
+ Key Efficiency: 99.3%  Bps in/out: 30.5k/162.8   Now in/out: 32.7k/ 3.3k
+
+The first line identifies the hostname of the server (localhost) and
+the version of MySQL it is running. The right had side shows the
+uptime of the MySQL server process in days+hours:minutes:seconds
+format (much like FreeBSD's top) as well as the current time.
+
+The second line displays the total number of queries the server has
+processed, the average number of queries per second, the number of
+slow queries, and the percentage of Select, Insert, Update, and Delete
+queries.
+
+The third real-time values. First is the number of queries per second,
+then the number of slow queries, followed by query precentages (like
+on the previous line).
+
+And the fourth line displays key buffer efficiency (how often keys are
+read from the buffer rather than disk) and the number of bytes that
+MySQL has sent and received, both over all and in the last cycle.
+
+You can toggle the header by hitting B<h> when running B<mytop>.
+
+The second part of the display lists as many threads as can fit on
+screen. By default they are sorted according to their idle time (least
+idle first). The display looks like:
+
+    Id     User       Host      Dbase   Time      Cmd Query or State
+    --     ----       ----      -----   ----      --- --------------
+    61  jzawodn  localhost      music      0    Query show processlist
+
+As you can see, the thread id, username, host from which the user is
+connecting, database to which the user is connected, number of seconds
+of idle time, the command the thread is executing, and the query info
+are all displayed.
+
+Often times the query info is what you are really interested in, so it
+is good to run B<mytop> in an xterm that is wider than the normal 80
+columns if possible.
+
+The thread display color-codes the threads if you have installed color
+support. The current color scheme only works well in a window with a
+dark (like black) background. The colors are selected according to the
+C<Command> column of the display:
+
+    Query   -  Yellow
+    Sleep   -  White
+    Connect -  Green
+    Slow    -  Bright
+    Long    -  Magenta
+
+Those are purely arbitrary and will be customizable in a future
+release. If they annoy you just start B<mytop> with the B<--nocolor>
+flag or adjust your config file appropriately.
+
+=head2 Arguments
+
+B<mytop> handles long and short command-line arguments. Not all
+options have both long and short formats, however. The long arguments
+have two dashes `--'. Short arguments only have one '-'.
+
+=over
+
+=item B<-u> or B<-user> username
+
+Username to use when logging in to the MySQL server. Default: ``root''.
+
+=item B<-p> or B<-pass> or B<-password> password
+
+Password to use when logging in to the MySQL server. Default: none.
+
+=item B<-h> or B<--host> hostname[:port]
+
+Hostname of the MySQL server. The hostname may be followed by an
+option port number. Note that the port is specified separate from the
+host when using a config file. Default: ``localhost''.
+
+=item B<--port> or B<-P> port
+
+If you're running MySQL on a non-standard port, use this to specify
+the port number. Default: 3306.
+
+=item B<-s> or B<--delay> seconds
+
+How long between display refreshes. Default: 5
+
+=item B<-d> or B<--db> or B<--database> database
+
+Use if you'd like B<mytop> to connect to a specific database by
+default. Default: ``test''.
+
+=item B<-b> or B<--batch> or B<--batchmode>
+
+In batch mode, mytop runs only once, does not clear the screen, and
+places no limit on the number of lines it will print. This is suitable
+for running periodically (perhaps from cron) to capture the
+information into a file for later viewing. You might use batch mode in
+a CGI script to occasionally display your MySQL server status on the
+web.
+
+Default: unset.
+
+=item B<-S> or B<--socket> /path/to/socket
+
+If you're running B<mytop> on the same host as MySQL, you may wish to
+have it use the MySQL socket directly rather than a standard TCP/IP
+connection. If you do,just specify one.
+
+Note that specifying a socket will make B<mytop> ignore any host
+and/or port that you might have specified. If the socket does not
+exist (or the file specified is not a socket), this option will be
+ignored and B<mytop> will use the hostname and port number instead.
+
+Default: none.
+
+=item B<--header> or B<--noheader>
+
+Sepcify if you want the header to display or not. You can toggle this
+with the B<h> key while B<mytop> is running.
+
+Default: header.
+
+=item B<--color> or B<--nocolor>
+
+Specify if you want a color display. This has no effect if you don't
+have color support available.
+
+Default: If you have color support, B<mytop> will try color unless you
+tell it not to.
+
+=item B<-i> or B<--idle> or B<--noi> or B<--noidle>
+
+Specify if you want idle (sleeping) threads to appear in the list. If
+sleeping threads are omitted, the default sorting order is reversed so
+that the longest running queries appear at the top of the list.
+
+Default: idle.
+
+=item B<--prompt> or B<--noprompt>
+
+Specify if you want to be prompted to type in your database password.
+This provides a little bit more security since it not only prevents
+the password from viewable in a process list, but also doesn't require
+the password to be stored in plain text in your ~/.mytop config file.
+You will B<only> be prompted if a password has not been specified in
+your config file or through another command line option.
+
+Default: noprompt.
+
+=item B<--resolve>
+
+If you have skip-resolve set on MySQL (to keep it from doing a reverse
+DNS lookup on each inbound connection), mytop can replace IP addresses
+with hostnames but toggling this option.
+
+Default: noresolve
+
+=back
+
+Command-line arguments will always take precedence over config file
+options. That happens because the config file is read I<BEFORE> the
+command-line arguments are applied.
+
+=head2 Config File
+
+Instead of always using bulky command-line parameters, you can also
+use a config files for the default value of your options.
+
+mytop will first read the [client] and [mytop] sections from your
+my.cnf files. After that it will read the (C<~/.mytop>) file from your
+home directory (if present). These are read I<before> any of your
+command-line arguments are processed, so your command-line arguments
+will override directives in the config file.
+
+
+Here is a sample config file C<~/.mytop> which implements the defaults
+described above.
+
+  user=root
+  pass=
+  host=localhost
+  db=test
+  delay=5
+  port=3306
+  slow=10
+  socket=
+  batchmode=0
+  header=1
+  color=1
+  idle=1
+  long=120
+
+Using a config file will help to ensure that your database password
+isn't visible to users on the command-line. Just make sure that the
+permissions on C<~/.mytop> are such that others cannot read it (unless
+you want them to, of course).
+
+You may have white space on either side of the C<=> in lines of the
+config file.
+
+=head2 Shortcut Keys
+
+The following keys perform various actions while B<mytop> is
+running. Those which have not been implemented are listed as
+such. They are included to give the user idea of what is coming.
+
+=over
+
+=item B<?>
+
+Display help.
+
+=item B<c>
+
+Show "command counters" based on the Com_* values in SHOW STATUS.
+This is a new feature.  Feedback welcome.
+
+=item B<C>
+
+Turn display color on and off. Default is on.
+
+=item B<d>
+
+Show only threads connected to a particular database.
+
+=item B<f>
+
+Given a thread id, display the entire query that thread was (and still
+may be) running.
+
+=item B<F>
+
+Disable all filtering (host, user, and db).
+
+=item B<h>
+
+Only show queries from a particular host.
+
+=item B<H>
+
+Toggle the header display. You can also specify either C<header=0> or
+C<header=1> in your config file to set the default behavior.
+
+=item B<i>
+
+Toggle the display of idle (sleeping) threads. If sleeping threads are
+filtered, the default sorting order is reversed so that the longest
+running queries appear at the top of the list.
+
+=item B<I>
+
+Switch to InnoDB Status mode.  The output of "SHOW INNODB STATUS" will
+be displayed every cycle.  In a future version, this may actually
+summarize that data rather than producing raw output.
+
+=item B<k>
+
+Kill a thread.
+
+=item B<m>
+
+Toggle modes. Currently this switches from `top' mode to `qps'
+(Queries Per Second Mode). In this mode, mytop will write out one
+integer per second. The number written reflects the number of queries
+executed by the server in the previous one second interval.
+
+More modes may be added in the future.
+
+=item B<o>
+
+Reverse the default sort order.
+
+=item B<p>
+
+Pause display.
+
+=item B<q>
+
+Quit B<mytop>
+
+=item B<r>
+
+Reset the server's status counters via a I<FLUSH STATUS> command.
+
+=item B<R>
+
+Togle IP reverse lookup. Default is on.
+
+=item B<s>
+
+Change the sleep time (number of seconds between display refreshes).
+
+=item B<S>
+
+Set the number of seconds a query will need to run before it is
+considered old and will be highlighted.
+
+=item B<u>
+
+Show only threads owned by a giver user.
+
+=back
+
+The B<s> key has a command-line counterpart: B<-s>.
+
+The B<h> key has two command-line counterparts: B<-header> and
+B<-noheader>.
+
+=head1 BUGS
+
+This is more of a BUGS + WishList.
+
+Some performance information is not available when talking to a
+version 3.22.x MySQL server. Additional information (about threads
+mostly) was added to the output of I<SHOW STATUS> in MySQL 3.23.x and
+B<mytop> makes use of it. If the information is not available, you
+will simply see zeros where the real numbers should be.
+
+Simply running this program will increase your overall counters (such
+as the number of queries run). But you may or may not view that as a
+bug.
+
+B<mytop> consumes too much CPU time when running (verified on older
+versions of Linux and FreeBSD). It's likely a problem related to
+Term::ReadKey. I haven't had time to investigate yet, so B<mytop> now
+automatically lowers its priority when you run it. You may also think
+about running B<mytop> on another workstation instead of your database
+server. However, C<mytop> on Solaris does B<not> have this problem.
+Newer versions of Linux and FreeBSD seem to have fixed this.
+
+You can't specify the maximum number of threads to list. If you have
+many threads and a tall xterm, B<mytop> will always try to display as
+many as it can fit.
+
+The size of most of the columns in the display has a small maximum
+width. If you have fairly long database/user/host names the display
+may appear odd. I have no good idea as to how best to deal with that
+yet. Suggestions are welcome.
+
+It'd be nice if you could just add B<mytop> configuration directives
+in your C<my.cnf> file instead of having a separate config file.
+
+You should be able to specify the columns you'd like to see in the
+display and the order in which they appear. If you only have one
+username that connects to your database, it's probably not worth
+having the User column appear, for example.

+  be set to 0 with clear_shapes() method and single value
+  can be changed with the invert_state() method.
+  Then the value of the relation can be calculated with the count() method.

+     The commit_ordered() method is called prior to the commit() method, after
+     the transaction manager has decided to commit (not rollback) the
+     transaction. Unlike commit(), commit_ordered() is called only when the
+     full transaction is committed, not for each commit of statement
+     transaction in a multi-statement transaction.
+
+     Not that like prepare(), commit_ordered() is only called when 2-phase
+     commit takes place. Ie. when no binary log and only a single engine
+     participates in a transaction, one commit() is called, no
+     commit_ordered(). So engines must be prepared for this.
+
+     The calls to commit_ordered() in multiple parallel transactions is
+     guaranteed to happen in the same order in every participating
+     handler. This can be used to ensure the same commit order among multiple
+     handlers (eg. in table handler and binlog). So if transaction T1 calls
+     into commit_ordered() of handler A before T2, then T1 will also call
+     commit_ordered() of handler B before T2.
+
+     Engines that implement this method should during this call make the
+     transaction visible to other transactions, thereby making the order of
+     transaction commits be defined by the order of commit_ordered() calls.
+
+     The intention is that commit_ordered() should do the minimal amount of
+     work that needs to happen in consistent commit order among handlers. To
+     preserve ordering, calls need to be serialised on a global mutex, so
+     doing any time-consuming or blocking operations in commit_ordered() will
+     limit scalability.
+
+     Handlers can rely on commit_ordered() calls to be serialised (no two
+     calls can run in parallel, so no extra locking on the handler part is
+     required to ensure this).
+
+     Note that commit_ordered() can be called from a different thread than the
+     one handling the transaction! So it can not do anything that depends on
+     thread local storage, in particular it can not call my_error() and
+     friends (instead it can store the error code and delay the call of
+     my_error() to the commit() method).
+
+     Similarly, since commit_ordered() returns void, any return error code
+     must be saved and returned from the commit() method instead.
+
+     The commit_ordered method is optional, and can be left unset if not
+     needed in a particular handler (then there will be no ordering guarantees
+     wrt. other engines and binary log).

+     The prepare_ordered method is optional. If set, it will be called after
+     successful prepare() in all handlers participating in 2-phase
+     commit. Like commit_ordered(), it is called only when the full
+     transaction is committed, not for each commit of statement transaction.
+
+     The calls to prepare_ordered() among multiple parallel transactions are
+     ordered consistently with calls to commit_ordered(). This means that
+     calls to prepare_ordered() effectively define the commit order, and that
+     each handler will see the same sequence of transactions calling into
+     prepare_ordered() and commit_ordered().
+
+     Thus, prepare_ordered() can be used to define commit order for handlers
+     that need to do this in the prepare step (like binlog). It can also be
+     used to release transaction's locks early in an order consistent with the
+     order transactions will be eventually committed.
+
+     Like commit_ordered(), prepare_ordered() calls are serialised to maintain
+     ordering, so the intention is that they should execute fast, with only
+     the minimal amount of work needed to define commit order. Handlers can
+     rely on this serialisation, and do not need to do any extra locking to
+     avoid two prepare_ordered() calls running in parallel.
+
+     Like commit_ordered(), prepare_ordered() is not guaranteed to be called
+     in the context of the thread handling the rest of the transaction. So it
+     cannot invoke code that relies on thread local storage, in particular it
+     cannot call my_error().
+
+     prepare_ordered() cannot cause a rollback by returning an error, all
+     possible errors must be handled in prepare() (the prepare_ordered()
+     method returns void). In case of some fatal error, a record of the error
+     must be made internally by the engine and returned from commit() later.
+
+     Note that for user-level XA SQL commands, no consistent ordering among
+     prepare_ordered() and commit_ordered() is guaranteed (as that would
+     require blocking all other commits for an indefinite time).

-  SYNOPSIS
-    Arg_comparator::can_compare_as_dates()
-    a, b          [in]  items to be compared
-    const_value   [out] converted value of the string constant, if any
-
-  DESCRIPTION
-    Check several cases when the DATE/DATETIME comparator should be used.
-    The following cases are checked:
-      1. Both a and b is a DATE/DATETIME field/function returning string or
-         int result.
-      2. Only a or b is a DATE/DATETIME field/function returning string or
-         int result and the other item (b or a) is an item with string result.
-         If the second item is a constant one then it's checked to be
-         convertible to the DATE/DATETIME type. If the constant can't be
-         converted to a DATE/DATETIME then the compare_datetime() comparator
-         isn't used and the warning about wrong DATE/DATETIME value is issued.
-      In all other cases (date-[int|real|decimal]/[int|real|decimal]-date)
-      the comparison is handled by other comparators.
-    If the datetime comparator can be used and one the operands of the
-    comparison is a string constant that was successfully converted to a
-    DATE/DATETIME type then the result of the conversion is returned in the
-    const_value if it is provided.  If there is no constant or
-    compare_datetime() isn't applicable then the *const_value remains
-    unchanged.

-  DESCRIPTION
+  @details
     Retrieves the correct DATETIME value from given item for comparison by the
     compare_datetime() function.
-    If item's result can be compared as longlong then its int value is used
-    and its string value is used otherwise. Strings are always parsed and
-    converted to int values by the get_date_from_str() function.
-    This allows us to compare correctly string dates with missed insignificant
-    zeros. If an item is a constant one then its value is cached and it isn't
-    get parsed again. An Item_cache_int object is used for caching values. It
-    seamlessly substitutes the original item.  The cache item is marked as
-    non-constant to prevent re-caching it again.  In order to compare
-    correctly DATE and DATETIME items the result of the former are treated as
-    a DATETIME with zero time (00:00:00).
 
-  RETURN
-    obtained value
+    If the value should be compared as time (TIME_RESULT), it's retrieved as
+    MYSQL_TIME. Otherwise it's read as a number/string and converted to time.
+    Constant items are cached, so the convertion is only done once for them.
+
+    Note the f_type behavior: if the item can be compared as time, then
+    f_type is this item's field_type(). Otherwise it's field_type() of
+    warn_item (which is the other operand of the comparison operator).
+    This logic provides correct string/number to date/time conversion
+    depending on the other operand (when comparing a string with a date, it's
+    parsed as a date, when comparing a string with a time it's parsed as a time)
+
+    If the item is a constant it is replaced by the Item_cache_int, that
+    holds the packed datetime value.
+
+  @return
+    MYSQL_TIME value, packed in a longlong, suitable for comparison.

-  Rewrite a single-column IN/ALL/ANY subselect
-
-  SYNOPSIS
-    Item_in_subselect::single_value_transformer()
-      join  Join object of the subquery (i.e. 'child' join).
-      func  Subquery comparison creator
-
-  DESCRIPTION
-    Rewrite a single-column subquery using rule-based approach. The subquery
-    
-       oe $cmp$ (SELECT ie FROM ... WHERE subq_where ... HAVING subq_having)
-    
-    First, try to convert the subquery to scalar-result subquery in one of
-    the forms:
-    
-       - oe $cmp$ (SELECT MAX(...) )  // handled by Item_singlerow_subselect
-       - oe $cmp$ <max>(SELECT ...)   // handled by Item_maxmin_subselect
-   
-    If that fails, the subquery will be handled with class Item_in_optimizer, 
-    Inject the predicates into subquery, i.e. convert it to:
-
-    - If the subquery has aggregates, GROUP BY, or HAVING, convert to
+/**
+  Prepare a single-column IN/ALL/ANY subselect for rewriting.
 
-       SELECT ie FROM ...  HAVING subq_having AND 
-                                   trigcond(oe $cmp$ ref_or_null_helper<ie>)
-                                   
-      the addition is wrapped into trigger only when we want to distinguish
-      between NULL and FALSE results.
+  @param join  Join object of the subquery (i.e. 'child' join).
 
-    - Otherwise (no aggregates/GROUP BY/HAVING) convert it to one of the
-      following:
+  @details
 
-      = If we don't need to distinguish between NULL and FALSE subquery:
-        
-        SELECT 1 FROM ... WHERE (oe $cmp$ ie) AND subq_where
+  Prepare a single-column subquery to be rewritten. Given the subquery.
 
-      = If we need to distinguish between those:
+  If the subquery has no tables it will be turned to an expression between
+  left part and SELECT list.
 
-        SELECT 1 FROM ...
-          WHERE  subq_where AND trigcond((oe $cmp$ ie) OR (ie IS NULL))
-          HAVING trigcond(<is_not_null_test>(ie))
+  In other cases the subquery will be wrapped with  Item_in_optimizer which
+  allow later to turn it to EXISTS or MAX/MIN.
 
-  RETURN
-    RES_OK     - OK, either subquery was transformed, or appopriate
-                 predicates where injected into it.
-    RES_REDUCE - The subquery was reduced to non-subquery
-    RES_ERROR  - Error
+  @retval false  The subquery was transformed
+  @retval true   Error

+    use subquery materialization at all.
+  - partial matching is either applicable or not, and this can be

+
+  A disk sweep read is a sequence of handler->rnd_pos(rowid) calls that made

+
+  We assume hard disk IO. The read is performed as follows:
+
+   1. The disk head is moved to the needed cylinder
+   2. The controller waits for the plate to rotate
+   3. The data is transferred
+
+  Time to do #3 is insignificant compared to #2+#1.
+
+  Time to move the disk head is proportional to head travel distance.
+
+  Time to wait for the plate to rotate depends on whether the disk head
+  was moved or not. 
+
+  If disk head wasn't moved, the wait time is proportional to distance
+  between the previous block and the block we're reading.
+
+  If the head was moved, we don't know how much we'll need to wait for the
+  plate to rotate. We assume the wait time to be a variate with a mean of
+  0.5 of full rotation time.
+
+  Our cost units are "random disk seeks". The cost of random disk seek is
+  actually not a constant, it depends one range of cylinders we're going
+  to access. We make it constant by introducing a fuzzy concept of "typical 
+  datafile length" (it's fuzzy as it's hard to tell whether it should
+  include index file, temp.tables etc). Then random seek cost is:
+
+    1 = half_rotation_cost + move_cost * 1/3 * typical_data_file_length

+  A Disk-Sweep implementation of MRR Interface (DS-MRR for short)
+
+  This is a "plugin"(*) for storage engines that allows to
+    1. When doing index scans, read table rows in rowid order;
+    2. when making many index lookups, do them in key order and don't
+       lookup the same key value multiple times;
+    3. Do both #1 and #2, when applicable.
+  These changes are expected to speed up query execution for disk-based 
+  storage engines running io-bound loads and "big" queries (ie. queries that
+  do joins and enumerate lots of records).
+
+  (*) - only conceptually. No dynamic loading or binary compatibility of any
+        kind.

+      (table records and range_ids)
+
+  The choice of strategy depends on MRR scan properties, table properties
+  (whether we're scanning clustered primary key), and @@optimizer_switch
+  settings.
+  
+  Key-Ordered Retrieval
+  ---------------------
+  The idea is: if MRR scan is essentially a series of lookups on 
+   
+    tbl.key=value1 OR tbl.key=value2 OR ... OR tbl.key=valueN
+  
+  then it makes sense to collect and order the set of lookup values, i.e.
+   
+     sort(value1, value2, .. valueN)
+
+  and then do index lookups in index order. This results in fewer index page
+  fetch operations, and we also can avoid making multiple index lookups for the
+  same value. That is, if value1=valueN we can easily discover that after
+  sorting and make one index lookup for them instead of two.
+
+  Rowid-Ordered Retrieval
+  -----------------------
+  If we do a regular index scan or a series of index lookups, we'll be hitting
+  table records at random. For disk-based engines, this is much slower than 
+  reading the same records in disk order. We assume that disk ordering of
+  rows is the same as ordering of their rowids (which is provided by 
+  handler::cmp_ref())
+  In order to retrieve records in different order, we must separate index
+  scanning and record fetching, that is, MRR scan uses the following steps:
+
+    1. Scan the index (and only index, that is, with HA_EXTRA_KEYREAD on) and 
+        fill a buffer with {rowid, range_id} pairs
+    2. Sort the buffer by rowid value
+    3. for each {rowid, range_id} pair in the buffer
+         get record by rowid and return the {record, range_id} pair
+    4. Repeat the above steps until we've exhausted the list of ranges we're
+       scanning.
+
+  Buffer space management considerations
+  --------------------------------------
+  With regards to buffer/memory management, MRR interface specifies that 
+   - SQL layer provides multi_range_read_init() with buffer of certain size.
+   - MRR implementation may use (i.e. have at its disposal till the end of 
+     the MRR scan) all of the buffer, or return the unused end of the buffer 
+     to SQL layer.
+
+  DS-MRR needs buffer in order to accumulate and sort rowids and/or keys. When
+  we need to accumulate/sort only keys (or only rowids), it is fairly trivial.
+
+  When we need to accumulate/sort both keys and rowids, efficient buffer use
+  gets complicated. We need to:
+   - First, accumulate keys and sort them
+   - Then use the keys (smaller values go first) to obtain rowids. A key is not
+     needed after we've got matching rowids for it.
+   - Make sure that rowids are accumulated at the front of the buffer, so that we
+     can return the end part of the buffer to SQL layer, should there be too
+     few rowid values to occupy the buffer.
+
+  All of these goals are achieved by using the following scheme:
+
+     |                    |   We get an empty buffer from SQL layer.   
+
+     |                  *-|    
+     |               *----|   First, we fill the buffer with keys. Key_buffer
+     |            *-------|   part grows from end of the buffer space to start
+     |         *----------|   (In this picture, the buffer is big enough to
+     |      *-------------|    accomodate all keys and even have some space left)
+
+     |      *=============|   We want to do key-ordered index scan, so we sort
+                              the keys
+
+     |-x      *===========|   Then we use the keys get rowids. Rowids are 
+     |----x      *========|   stored from start of buffer space towards the end.
+     |--------x     *=====|   The part of the buffer occupied with keys
+     |------------x   *===|   gradually frees up space for rowids. In this
+     |--------------x   *=|   picture we run out of keys before we've ran out
+     |----------------x   |   of buffer space (it can be other way as well).
+
+     |================x   |   Then we sort the rowids.
+                     
+     |                |~~~|   The unused part of the buffer is at the end, so
+                              we can return it to the SQL layer.
+
+     |================*       Sorted rowids are then used to read table records 
+                              in disk order

+    make_cond_for_index()
+      cond           The source condition
+      table          The table that is partially available
+      keyno          The index in the above table. Only fields covered by the index
+                     are available

+
+  DESCRIPTION
+    Get a part of the condition that can be checked when for the given table 
+    we have values only of fields covered by some index. The condition may
+    refer to other tables, it is assumed that we have values of all of their 
+    fields.
+
+    Example:

+         "cond(t1.field) AND cond(t2.key1) AND cond(t2.non_key) AND cond(t2.key2)",
+          t2, keyno(t2.key1)) 
+      will return
+        "cond(t1.field) AND cond(t2.key2)"

+  KeyTupleFormat
+  ~~~~~~~~~~~~~~
+  The code in this file (and elsewhere) makes operations on key value tuples.
+  Those tuples are stored in the following format:
+  
+  The tuple is a sequence of key part values. The length of key part value
+  depends only on its type (and not depends on the what value is stored)
+  
+    KeyTuple: keypart1-data, keypart2-data, ...
+  
+  The value of each keypart is stored in the following format:
+  
+    keypart_data: [isnull_byte] keypart-value-bytes
+
+  If a keypart may have a NULL value (key_part->field->real_maybe_null() can
+  be used to check this), then the first byte is a NULL indicator with the 
+  following valid values:
+    1  - keypart has NULL value.
+    0  - keypart has non-NULL value.
+
+  <questionable-statement> If isnull_byte==1 (NULL value), then the following
+  keypart->length bytes must be 0.
+  </questionable-statement>
+
+  keypart-value-bytes holds the value. Its format depends on the field type.
+  The length of keypart-value-bytes may or may not depend on the value being
+  stored. The default is that length is static and equal to 
+  KEY_PART_INFO::length.
+  
+  Key parts with (key_part_flag & HA_BLOB_PART) have length depending of the 
+  value:
+  
+     keypart-value-bytes: value_length value_bytes
+
+  The value_length part itself occupies HA_KEY_BLOB_LENGTH=2 bytes.

+  and table record

+  While objects of the class SEL_ARG represent ranges for indexes or
+  index infixes (including ranges for index prefixes and index suffixes),
+  objects of the class SEL_TREE represent AND/OR formulas of such ranges.
+  Currently an AND/OR formula represented by a SEL_TREE object can have
+  at most three levels: 
+
+    <SEL_TREE formula> ::= 
+      [ <SEL_RANGE_TREE formula> AND ]
+      [ <SEL_IMERGE formula> [ AND <SEL_IMERGE formula> ...] ]
+
+    <SEL_RANGE_TREE formula> ::=
+      <SEL_ARG formula> [ AND  <SEL_ARG_formula> ... ]
+
+    <SEL_IMERGE formula> ::=  
+      <SEL_RANGE_TREE formula> [ OR <SEL_RANGE_TREE formula> ]
+
+  As we can see from the above definitions:
+   - SEL_RANGE_TREE formula is a conjunction of SEL_ARG formulas
+   - SEL_IMERGE formula is a disjunction of SEL_RANGE_TREE formulas
+   - SEL_TREE formula is a conjunction of a SEL_RANGE_TREE formula
+     and SEL_IMERGE formulas. 
+  It's required above that a SEL_TREE formula has at least one conjunct.
+
+  Usually we will consider normalized SEL_RANGE_TREE formulas where we use
+  TRUE as conjunct members for those indexes whose SEL_ARG trees are empty.
+  
+  We will call an SEL_TREE object simply 'tree'. 
+  The part of a tree that represents SEL_RANGE_TREE formula is called
+  'range part' of the tree while the remaining part is called 'imerge part'. 
+  If a tree contains only a range part then we call such a tree 'range tree'.
+  Components of a range tree that represent SEL_ARG formulas are called ranges.
+  If a tree does not contain any range part we call such a tree 'imerge tree'.
+  Components of the imerge part of a tree that represent SEL_IMERGE formula
+  are called imerges.
+
+  Usually we'll designate:
+    SEL_TREE formulas         by T_1,...,T_k
+    SEL_ARG formulas          by R_1,...,R_k
+    SEL_RANGE_TREE formulas   by RT_1,...,RT_k
+    SEL_IMERGE formulas       by M_1,...,M_k
+  Accordingly we'll use:
+    t_1,...,t_k - to designate trees representing T_1,...,T_k
+    r_1,...,r_k - to designate ranges representing R_1,...,R_k 
+    rt_1,...,r_tk - to designate range trees representing RT_1,...,RT_k
+    m_1,...,m_k - to designate imerges representing M_1,...,M_k
+
+  SEL_TREE objects are usually built from WHERE conditions or
+  ON expressions.
+  A SEL_TREE object always represents an inference of the condition it is
+  built from. Therefore, if a row satisfies a SEL_TREE formula it also
+  satisfies the condition it is built from.
+
+  The following transformations of tree t representing SEL_TREE formula T 
+  yield a new tree t1 thar represents an inference of T: T=>T1.  
+    (1) remove any of SEL_ARG tree from the range part of t
+    (2) remove any imerge from the tree t 
+    (3) remove any of SEL_ARG tree from any range tree contained
+        in any imerge of tree   
+ 
+  Since the basic blocks of any SEL_TREE objects are ranges, SEL_TREE
+  objects in many cases can be effectively used to filter out a big part
+  of table rows that do not satisfy WHERE/IN conditions utilizing
+  only single or multiple range index scans.
+
+  A single range index scan is constructed for a range tree that contains
+  only one SEL_ARG object for an index or an index prefix.
+  An index intersection scan can be constructed for a range tree
+  that contains several SEL_ARG objects. Currently index intersection
+  scans are constructed only for single-point ranges.
+  An index merge scan is constructed for a imerge tree that contains only
+  one imerge. If range trees of this imerge contain only single-point merges
+  than a union of index intersections can be built.
+
+  Usually the tree built by the range optimizer for a query table contains
+  more than one range in the range part, and additionally may contain some
+  imerges in the imerge part. The range optimizer evaluates all of them one
+  by one and chooses the range or the imerge that provides the cheapest
+  single or multiple range index scan of the table.  According to rules 
+  (1)-(3) this scan always filter out only those rows that do not satisfy
+  the query conditions. 
+
+  For any condition the SEL_TREE object for it is built in a bottom up
+  manner starting from the range trees for the predicates. The tree_and
+  function builds a tree for any conjunction of formulas from the trees
+  for its conjuncts. The tree_or function builds a tree for any disjunction
+  of formulas from the trees for its disjuncts.

+
+  DESCRIPTION
+    The function performs OR operation on this imerge m and the range part
+    of the SEL_TREE tree rt. It always replaces this imerge with the result
+    of the operation.
+ 
+    The operation can be performed in two different modes: with
+    is_first_check_pass==TRUE and is_first_check_pass==FALSE, transforming
+    this imerge differently.
+
+    Given this imerge represents the formula
+      RT_1 OR ... OR RT_k:
+
+    1. In the first mode, when is_first_check_pass==TRUE :
+      1.1. If rt must be ored(see the function sel_trees_must_be_ored) with
+           some rt_j (there may be only one such range tree in the imerge)
+           then the function produces an imerge representing the formula
+             RT_1 OR ... OR (RT_j OR RT) OR ... OR RT_k,
+           where the tree for (RT_j OR RT) is built by oring the pairs
+           of SEL_ARG trees for the corresponding indexes
+      1.2. Otherwise the function produces the imerge representing the formula:
+           RT_1 OR ... OR RT_k OR RT.
+
+    2. In the second mode, when is_first_check_pass==FALSE :
+      2.1. For each rt_j in the imerge that can be ored (see the function
+           sel_trees_can_be_ored) with rt the function replaces rt_j for a
+           range tree such that for each index for which ranges are defined
+           in both in rt_j and rt  the tree contains the  result of oring of
+           these ranges.
+      2.2. In other cases the function does not produce any imerge.

+      im2               The second imerge list for the operation
+     
+  DESCRIPTION
+    Assuming that the first imerge list represents the formula
+      F1= M1_1 AND ... AND M1_k1 
+    while the second imerge list represents the formula 
+      F2= M2_1 AND ... AND M2_k2,
+    where M1_i= RT1_i_1 OR ... OR RT1_i_l1i (i in [1..k1])
+    and M2_i = RT2_i_1 OR ... OR RT2_i_l2i (i in [1..k2]),
+    the function builds a list of imerges for some formula that can be 
+    inferred from the formula (F1 OR F2).
+
+    More exactly the function builds imerges for the formula (M1_1 OR M2_1).
+    Note that
+      (F1 OR F2) = (M1_1 AND ... AND M1_k1) OR (M2_1 AND ... AND M2_k2) =
+      AND (M1_i OR M2_j) (i in [1..k1], j in [1..k2]) =>
+      M1_1 OR M2_1.
+    So (M1_1 OR M2_1) is indeed an inference formula for (F1 OR F2).
+
+    To build imerges for the formula (M1_1 OR M2_1) the function invokes,
+    possibly twice, the method SEL_IMERGE::or_sel_imerge_with_checks
+    for the imerge m1_1.
+    At its first invocation the method SEL_IMERGE::or_sel_imerge_with_checks
+    performs OR operation on the imerge m1_1 and the range tree rt2_1_1 by
+    calling SEL_IMERGE::or_sel_tree_with_checks with is_first_pass_check==TRUE.
+    The resulting imerge of the operation is ored with the next range tree of
+    the imerge m2_1. This oring continues until the last range tree from
+    m2_1 has been ored. 
+    At its second invocation the method SEL_IMERGE::or_sel_imerge_with_checks
+    performs the same sequence of OR operations, but now calling
+    SEL_IMERGE::or_sel_tree_with_checks with is_first_pass_check==FALSE.

+
+  DESCRIPTION
+    For each imerge mi from the list 'merges' the function performes OR
+    operation with mi and the range part of 'tree' rt, producing one or
+    two imerges.
+
+    Given the merge mi represent the formula RTi_1 OR ... OR RTi_k, 
+    the function forms the merges by the following rules:
+ 
+    1. If rt cannot be ored with any of the trees rti the function just
+       produces an imerge that represents the formula
+         RTi_1 OR ... RTi_k OR RT.
+    2. If there exist a tree rtj that must be ored with rt the function
+       produces an imerge the represents the formula
+         RTi_1 OR ... OR (RTi_j OR RT) OR ... OR RTi_k,
+       where the range tree for (RTi_j OR RT) is constructed by oring the
+       SEL_ARG trees that must be ored.
+    3. For each rti_j that can be ored with rt the function produces
+       the new tree rti_j' and substitutes rti_j for this new range tree.
+
+    In any case the function removes mi from the list and then adds all
+    produced imerges.
+
+    To build imerges by rules 1-3 the function calls the method
+    SEL_IMERGE::or_sel_tree_with_checks, possibly twice. With the first
+    call it passes TRUE for the third parameter of the function.
+    At this first call imerges by rules 1-2 are built. If the call
+    returns FALSE as the return value of its fourth parameter then the
+    function are called for the second time. At this call the imerge
+    of rule 3 is produced.
+
+    If a call of SEL_IMERGE::or_sel_tree_with_checks returns 1 then
+    then it means that the produced tree contains an always true
+    range tree and the whole imerge can be discarded.
+    
   RETURN
-    0     OK, result is stored in *im1.
-    other Error

+    rt of 'tree' into the imerge. 
+    More exactly if the imerge mi from the list represents the formula
+      RTi_1 OR ... OR RTi_k 
+    the function bulds a new imerge that represents the formula
+      (RTi_1 AND RT) OR ... OR (RTi_k AND RT)
+    and adds this imerge to the list merges.
+    To perform this pushdown operation the function calls the method
+    SEL_IMERGE::and_sel_tree. 
+    For any imerge mi the new imerge is not created if for each pair of
+    trees rti_j and rt the intersection of the indexes with defined ranges
+    is empty.
+    If the result of the pushdown operation for the imerge mi returns an
+    imerge with no trees then then not only nothing is added to the list 
+    merges but mi itself is removed from the list. 
+
+  TODO
+    Optimize the code in order to not create new SEL_IMERGE and new SER_TREE
+    objects when 'replace' is TRUE. (Currently this function is called always
+    with this parameter equal to TRUE.)
+    
+  RETURN
+    1    if no imerges are left in the list merges             
+    0    otherwise

+    merge_same_index_scans()
+      param           Context info for the operation
+      imerge   IN/OUT SEL_IMERGE from which imerge_trp has been extracted          
+      imerge_trp      The index merge plan where index scans for the same
+                      indexes are to be merges
+      read_time       The upper bound for the cost of the plan to be evaluated
+
+  DESRIPTION
+    For the given index merge plan imerge_trp extracted from the SEL_MERGE
+    imerge the function looks for range scans with the same indexes and merges
+    them into SEL_ARG trees. Then for each such SEL_ARG tree r_i the function
+    creates a range tree rt_i that contains only r_i. All rt_i are joined
+    into one index merge that replaces the original index merge imerge.
+    The function calls get_best_disjunct_quick for the new index merge to
+    get a new index merge plan that contains index scans only for different
+    indexes.
+    If there are no index scans for the same index in the original index
+    merge plan the function does not change the original imerge and returns
+    imerge_trp as its result.

+  RETURN

+    conditions. These indexes always have the same prefixes and the
+    components of this prefixes are exactly those used in these range
+    conditions.
+    Range conditions over clustered primary key (cpk) is always used only
+    as the condition that filters out some rowids retrieved by the scans

+  On Estimation of the Number of Records in an Index Intersection 
+  ===============================================================
+
+  Consider query Q over table t. Let C be the WHERE condition of  this query,
+  and, idx1(a1_1,...,a1_k1) and idx2(a2_1,...,a2_k2) be some indexes defined
+  on table t.
+  Let rt1 and rt2 be the range trees extracted by the range optimizer from C
+  for idx1 and idx2 respectively.
+  Let #t be the estimate of the number of records in table t provided for the
+  optimizer. 
+  Let #r1 and #r2 be the estimates of the number of records in the range trees
+  rt1 and rt2, respectively, obtained by the range optimizer.
+
+  We need to get an estimate for the number of records in the index 
+  intersection of rt1 and rt2. In other words, we need to estimate the
+  cardinality of the set of records that are in both trees. Let's designate
+  this number by #r.
+
+  If we do not make any assumptions then we can only state that
+     #r<=min(#r1,#r2).
+  With this estimate we can't say that the index intersection scan will be 
+  cheaper than the cheapest index scan.
+
+  Let Rt1 and Rt2 be AND/OR conditions representing rt and rt2 respectively.
+  The probability that a record belongs to rt1 is sel(Rt1)=#r1/#t.
+  The probability that a record belongs to rt2 is sel(Rt2)=#r2/#t.
+
+  If we assume that the values in columns of idx1 and idx2 are independent
+  then #r/#t=sel(Rt1&Rt2)=sel(Rt1)*sel(Rt2)=(#r1/#t)*(#r2/#t).
+  So in this case we have: #r=#r1*#r2/#t.
+
+  The above assumption of independence of the columns in idx1 and idx2 means
+  that:
+  - all columns are different
+  - values from one column do not correlate with values from any other column.
+
+  We can't help with the case when column correlate with each other.
+  Yet, if they are assumed to be uncorrelated the value of #r theoretically can
+  be evaluated . Unfortunately this evaluation, in general, is rather complex.
+
+  Let's consider two indexes idx1:(dept, manager),  idx2:(dept, building)
+  over table 'employee' and two range conditions over these indexes:
+    Rt1: dept=10 AND manager LIKE 'S%'
+    Rt2: dept=10 AND building LIKE 'L%'.
+  We can state that:
+    sel(Rt1&Rt2)=sel(dept=10)*sel(manager LIKE 'S%')*sel(building LIKE 'L%')
+    =sel(Rt1)*sel(Rt2)/sel(dept=10).
+  sel(Rt1/2_0:dept=10) can be estimated if we know the cardinality #r1_0 of
+  the range for sub-index idx1_0 (dept) of the index idx1 or the cardinality
+  #rt2_0 of the same range for sub-index idx2_0(dept) of the index idx2.
+  The current code does not make an estimate either for #rt1_0, or for #rt2_0,
+  but it can be adjusted to provide those numbers.
+  Alternatively, min(rec_per_key) for (dept) could be used to get an upper 
+  bound for the value of sel(Rt1&Rt2). Yet this statistics is not provided
+  now.  
+ 
+  Let's consider two other indexes idx1:(dept, last_name), 
+  idx2:(first_name, last_name) and two range conditions over these indexes:
+    Rt1: dept=5 AND last_name='Sm%'
+    Rt2: first_name='Robert' AND last_name='Sm%'.
+
+  sel(Rt1&Rt2)=sel(dept=5)*sel(last_name='Sm5')*sel(first_name='Robert')
+  =sel(Rt2)*sel(dept=5)
+  Here max(rec_per_key) for (dept) could be used to get an upper bound for
+  the value of sel(Rt1&Rt2).
+  
+  When the intersected indexes have different major columns, but some
+  minor column are common the picture may be more complicated.
+
+  Let's consider the following range conditions for the same indexes as in
+  the previous example:
+    Rt1: (Rt11: dept=5 AND last_name='So%') 
+         OR 
+         (Rt12: dept=7 AND last_name='Saw%')
+    Rt2: (Rt21: first_name='Robert' AND last_name='Saw%')
+         OR
+         (Rt22: first_name='Bob' AND last_name='So%')
+  Here we have:
+  sel(Rt1&Rt2)= sel(Rt11)*sel(Rt21)+sel(Rt22)*sel(dept=5) +
+                sel(Rt21)*sel(dept=7)+sel(Rt12)*sel(Rt22)
+  Now consider the range condition:
+    Rt1_0: (dept=5 OR dept=7)
+  For this condition we can state that:
+  sel(Rt1_0&Rt2)=(sel(dept=5)+sel(dept=7))*(sel(Rt21)+sel(Rt22))=
+  sel(dept=5)*sel(Rt21)+sel(dept=7)*sel(Rt21)+
+  sel(dept=5)*sel(Rt22)+sel(dept=7)*sel(Rt22)=
+  sel(dept=5)*sel(Rt21)+sel(Rt21)*sel(dept=7)+
+  sel(Rt22)*sel(dept=5)+sel(dept=7)*sel(Rt22) >
+  sel(Rt11)*sel(Rt21)+sel(Rt22)*sel(dept=5)+
+  sel(Rt21)*sel(dept=7)+sel(Rt12)*sel(Rt22) >
+  sel(Rt1 & Rt2) 
+
+ We've just demonstrated for an example what is intuitively almost obvious
+ in general. We can  remove the ending parts fromrange trees getting less
+ selective range conditions for sub-indexes.
+ So if not a most major component with the number k of an index idx is
+ encountered in the index with which we intersect we can use the sub-index
+ idx_k-1 that includes the components of idx up to the i-th component and
+ the range tree for idx_k-1 to make an upper bound estimate for the number
+  of records in the index intersection.
+ The range tree for idx_k-1 we use here is the subtree of the original range
+  tree for idx that contains only parts from the first k-1 components.
+
+  As it was mentioned above the range optimizer currently does not provide
+  an estimate for the number of records in the ranges for sub-indexes.
+  However, some reasonable upper bound estimate can be obtained.
+
+  Let's consider the following range tree:
+    Rt: (first_name='Robert' AND last_name='Saw%')
+        OR
+        (first_name='Bob' AND last_name='So%')
+  Let #r be the number of records in Rt. Let f_1 be the fan-out of column
+  last_name:
+    f_1 = rec_per_key[first_name]/rec_per_key[last_name].
+  The the number of records in the range tree:
+    Rt_0:  (first_name='Robert' OR first_name='Bob')
+  for the sub-index (first_name) is not greater than max(#r*f_1, #t).
+  Strictly speaking, we can state only that it's not greater than 
+  max(#r*max_f_1, #t), where
+    max_f_1= max_rec_per_key[first_name]/min_rec_per_key[last_name].
+  Yet, if #r/#t is big enough (and this is the case of an index intersection,
+  because using this index range with a single index scan is cheaper than
+  the cost of the intersection when #r/#t is small) then almost safely we
+  can use here f_1 instead of max_f_1.
+
+  The above considerations can be used in future development. Now, they are
+  used partly in the function that provides a rough upper bound estimate for
+  the number of records in an index intersection that follow below.

+
+    The function assumes that tree1 is never equal to tree2. At the same

+  SYNOPSIS
+    tree_and()
+      param           Context info for the operation
+      tree1           SEL_TREE for the first conjunct          
+      tree2           SEL_TREE for the second conjunct
+
+  DESCRIPTION
+    This function builds a tree for the formula (A AND B) out of the trees
+    tree1 and tree2 that has been built for the formulas A and B respectively.
+
+    In a general case
+      tree1 represents the formula RT1 AND MT1,
+        where RT1 = R1_1 AND ... AND R1_k1, MT1=M1_1 AND ... AND M1_l1;
+      tree2 represents the formula RT2 AND MT2 
+        where RT2 = R2_1 AND ... AND R2_k2, MT2=M2_1 AND ... AND M2_l2.
+
+    The result tree will represent the formula of the the following structure:
+      RT AND RT1MT2 AND RT2MT1, such that
+        rt is a tree obtained by range intersection of trees tree1 and tree2,
+        RT1MT2 = RT1M2_1 AND ... AND RT1M2_l2,
+        RT2MT1 = RT2M1_1 AND ... AND RT2M1_l1,
+        where rt1m2_i (i=1,...,l2) is the result of the pushdown operation
+        of range tree rt1 into imerge m2_i, while rt2m1_j (j=1,...,l1) is the
+        result of the pushdown operation of range tree rt2 into imerge m1_j.
+
+    RT1MT2/RT2MT is empty if MT2/MT1 is empty.
+ 
+    The range intersection of two range trees is produced by the function
+    and_range_trees. The pushdown of a range tree to a imerge is performed
+    by the function imerge_list_and_tree. This function may produce imerges
+    containing only one range tree. Such trees are intersected with rt and 
+    the result of intersection is returned as the range part of the result
+    tree, while the corresponding imerges are removed altogether from its
+    imerge part. 
+    
+  NOTE
+    The pushdown operation of range trees into imerges is needed to be able
+    to construct valid imerges for the condition like this:
+      key1_p1=c1 AND (key1_p2 BETWEEN c21 AND c22 OR key2 < c2)
+
+  NOTE
+    Currently we do not support intersection between indexes and index merges.
+    When this will be supported the list of imerges for the result tree
+    should include also imerges from M1 and M2. That's why an extra parameter
+    is added to the function imerge_list_and_tree. If we call the function
+    with the last parameter equal to FALSE then MT1 and MT2 will be preserved
+    in the imerge list of the result tree. This can lead to the exponential
+    growth of the imerge list though. 
+    Currently the last parameter of imerge_list_and_tree calls is always
+    TRUE.
+
+  RETURN
+    The result tree, if a success
+    0 - otherwise.

     A SEL_ARG* tree cannot be used to construct quick select if it has
     tree->part != 0. (e.g. it could represent "keypart2 < const").
-
-    WHY THIS FUNCTION IS NEEDED
     
     Normally we allow construction of SEL_TREE objects that have SEL_ARG
-    trees that do not allow quick range select construction. For example for
-    " keypart1=1 AND keypart2=2 " the execution will proceed as follows:
+    trees that do not allow quick range select construction.
+    For example:
+    for " keypart1=1 AND keypart2=2 " the execution will proceed as follows:
     tree1= SEL_TREE { SEL_ARG{keypart1=1} }
     tree2= SEL_TREE { SEL_ARG{keypart2=2} } -- can't make quick range select
                                                from this
     call tree_and(tree1, tree2) -- this joins SEL_ARGs into a usable SEL_ARG
                                    tree.
-    
-    There is an exception though: when we construct index_merge SEL_TREE,
-    any SEL_ARG* tree that cannot be used to construct quick range select can
-    be removed, because current range analysis code doesn't provide any way
-    that tree could be later combined with another tree.
-    Consider an example: we should not construct
-    st1 = SEL_TREE { 
-      merges = SEL_IMERGE { 
-                            SEL_TREE(t.key1part1 = 1), 
-                            SEL_TREE(t.key2part2 = 2)   -- (*)
-                          } 
-                   };
-    because 
-     - (*) cannot be used to construct quick range select, 
-     - There is no execution path that would cause (*) to be converted to 
-       a tree that could be used.
-
-    The latter is easy to verify: first, notice that the only way to convert
-    (*) into a usable tree is to call tree_and(something, (*)).
-
-    Second look at what tree_and/tree_or function would do when passed a
-    SEL_TREE that has the structure like st1 tree has, and conlcude that 
-    tree_and(something, (*)) will not be called.
 
+    Another example:
+    tree3= SEL_TREE { SEL_ARG{key1part1 = 1} }
+    tree4= SEL_TREE { SEL_ARG{key2part2 = 2} }  -- can't make quick range select
+                                               from this
+    call tree_or(tree3, tree4) -- creates a SEL_MERGE ot of which no index
+    merge can be constructed, but it is potentially useful, as anding it with
+    tree5= SEL_TREE { SEL_ARG{key2part1 = 3} } creates an index merge that
+    represents the formula
+      key1part1=1 AND key2part1=3 OR key2part1=3 AND key2part2=2 
+    for which an index merge can be built. 
+
+    Any final SEL_TREE may contain SEL_ARG trees for which no quick select
+    can be built. Such SEL_ARG trees should be removed from the range part
+    before different range scans are evaluated. Such SEL_ARG trees also should
+    be removed from all range trees of each index merge before different

+    must be discarded.

+  Build a SEL_TREE for a disjunction out of such trees for the disjuncts
+
+  SYNOPSIS
+    tree_or()
+      param           Context info for the operation
+      tree1           SEL_TREE for the first disjunct          
+      tree2           SEL_TREE for the second disjunct
+
+  DESCRIPTION
+    This function builds a tree for the formula (A OR B) out of the trees
+    tree1 and tree2 that has been built for the formulas A and B respectively.
+
+    In a general case
+      tree1 represents the formula RT1 AND MT1,
+        where RT1=R1_1 AND ... AND R1_k1, MT1=M1_1 AND ... AND M1_l1;
+      tree2 represents the formula RT2 AND MT2 
+        where RT2=R2_1 AND ... AND R2_k2, MT2=M2_1 and ... and M2_l2.
+
+    The function constructs the result tree according the formula
+      (RT1 OR RT2) AND (MT1 OR RT1) AND (MT2 OR RT2) AND (MT1 OR MT2)
+    that is equivalent to the formula (RT1 AND MT1) OR (RT2 AND MT2).
+
+    To limit the number of produced imerges the function considers
+    a weaker formula than the original one:
+      (RT1 AND M1_1) OR (RT2 AND M2_1) 
+    that is equivalent to:
+      (RT1 OR RT2)                  (1)
+        AND 
+      (M1_1 OR M2_1)                (2)
+        AND
+      (M1_1 OR RT2)                 (3)
+        AND
+      (M2_1 OR RT1)                 (4)
+
+    For the first conjunct (1) the function builds a tree with a range part
+    and, possibly, one imerge. For the other conjuncts (2-4)the function
+    produces sets of imerges. All constructed imerges are included into the
+    result tree.
+    
+    For the formula (1) the function produces the tree representing a formula  
+    of the structure RT [AND M], such that:
+     - the range tree rt contains the result of oring SEL_ARG trees from rt1
+       and rt2
+     - the imerge m consists of two range trees rt1 and rt2.
+    The imerge m is added if it's not true that rt1 and rt2 must be ored
+    If rt1 and rt2 can't be ored rt is empty and only m is produced for (1).
+
+    To produce imerges for the formula (2) the function calls the function
+    imerge_list_or_list passing it the merge parts of tree1 and tree2 as
+    parameters.
+
+    To produce imerges for the formula (3) the function calls the function
+    imerge_list_or_tree passing it the imerge m1_1 and the range tree rt2 as
+    parameters. Similarly, to produce imerges for the formula (4) the function
+    calls the function imerge_list_or_tree passing it the imerge m2_1 and the
+    range tree rt1.
+
+    If rt1 is empty then the trees for (1) and (4) are empty.
+    If rt2 is empty then the trees for (1) and (3) are empty.
+    If mt1 is empty then the trees for (2) and (3) are empty.
+    If mt2 is empty then the trees for (2) and (4) are empty.
+
+  RETURN
+    The result tree for the operation if a success

-  Recursively calculate estimate of # rows that will be retrieved by
-  key scan on key idx.
-  SYNOPSIS
-    check_quick_keys()
-      param         Parameter from test_quick select function.
-      idx           Number of key to use in PARAM::keys in list of used keys
-                    (param->real_keynr[idx] holds the key number in table)
-      key_tree      SEL_ARG tree being examined.
-      min_key       Buffer with partial min key value tuple
-      min_key_flag
-      max_key       Buffer with partial max key value tuple
-      max_key_flag
-
-  NOTES
-    The function does the recursive descent on the tree via SEL_ARG::left,
-    SEL_ARG::right, and SEL_ARG::next_key_part edges. The #rows estimates
-    are calculated using records_in_range calls at the leaf nodes and then
-    summed.
-
-    param->min_key and param->max_key are used to hold prefixes of key value
-    tuples.
-
-    The side effects are:
-
-    param->max_key_part is updated to hold the maximum number of key parts used
-      in scan minus 1.
-
-    param->range_count is incremented if the function finds a range that
-      wasn't counted by the caller.
-
-    param->is_ror_scan is cleared if the function detects that the key scan is
-      not a Rowid-Ordered Retrieval scan ( see comments for is_key_scan_ror
-      function for description of which key scans are ROR scans)
-
-  RETURN
-    #records      E(#records) for given subtree
-    HA_POS_ERROR  if subtree cannot be used for record retrieval

   SYNOPSIS
     check_group_min_max_predicates()
-    cond              tree (or subtree) describing all or part of the WHERE
-                      clause being analyzed
-    min_max_arg_item  the field referenced by the MIN/MAX function(s)
-    min_max_arg_part  the keypart of the MIN/MAX argument if any
+    cond        [in]  the expression tree being analyzed
+    min_max_arg [in]  the field referenced by the MIN/MAX function(s)
+    image_type  [in]
+    has_min_max_arg [out] true if the subtree being analyzed references min_max_arg
+    has_other_arg   [out] true if the subtree being analyzed references a column
+                          other min_max_arg
 
   DESCRIPTION
     The function walks recursively over the cond tree representing a WHERE
     clause, and checks condition (SA3) - if a field is referenced by a MIN/MAX
     aggregate function, it is referenced only by one of the following
-    predicates: {=, !=, <, <=, >, >=, between, is null, is not null}.
+    predicates $FUNC$:
+    {=, !=, <, <=, >, >=, between, is [not] null, multiple equal}.
+    In addition the function checks that the WHERE condition is equivalent to
+    "cond1 AND cond2" where :
+    cond1 - does not use min_max_column at all.
+    cond2 - is an AND/OR tree with leaves in form
+    "$FUNC$(min_max_column[, const])".
 
   RETURN
     TRUE  if cond passes the test

+  This file contains optimizations for semi-join subqueries.
+  
+  Contents
+  --------
+  1. What is a semi-join subquery
+  2. General idea about semi-join execution
+  2.1 Correlated vs uncorrelated semi-joins
+  2.2 Mergeable vs non-mergeable semi-joins
+  3. Code-level view of semi-join processing
+  3.1 Conversion
+  3.1.1 Merged semi-join TABLE_LIST object
+  3.1.2 Non-merged semi-join data structure
+  3.2 Semi-joins and query optimization
+  3.2.1 Non-merged semi-joins and join optimization
+  3.2.2 Merged semi-joins and join optimization
+  3.3 Semi-joins and query execution
+
+  1. What is a semi-join subquery
+  -------------------------------
+  We use this definition of semi-join:
+
+    outer_tbl SEMI JOIN inner_tbl ON cond = {set of outer_tbl.row such that
+                                             exist inner_tbl.row, for which 
+                                             cond(outer_tbl.row,inner_tbl.row)
+                                             is satisfied}
+  
+  That is, semi-join operation is similar to inner join operation, with
+  exception that we don't care how many matches a row from outer_tbl has in
+  inner_tbl.
+
+  In SQL terms: a semi-join subquery is an IN subquery that is an AND-part of
+  the WHERE/ON clause.
+
+  2. General idea about semi-join execution
+  -----------------------------------------
+  We can execute semi-join in a way similar to inner join, with exception that
+  we need to somehow ensure that we do not generate record combinations that
+  differ only in rows of inner tables.
+  There is a number of different ways to achieve this property, implemented by
+  a number of semi-join execution strategies.
+  Some strategies can handle any semi-joins, other can be applied only to
+  semi-joins that have certain properties that are described below:
+
+  2.1 Correlated vs uncorrelated semi-joins
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Uncorrelated semi-joins are special in the respect that they allow to
+   - execute the subquery (possible as it's uncorrelated)
+   - somehow make sure that generated set does not have duplicates
+   - perform an inner join with outer tables.
+  
+  or, rephrasing in SQL form:
+
+  SELECT ... FROM ot WHERE ot.col IN (SELECT it.col FROM it WHERE uncorr_cond)
+    ->
+  SELECT ... FROM ot JOIN (SELECT DISTINCT it.col FROM it WHERE uncorr_cond)
+
+  2.2 Mergeable vs non-mergeable semi-joins
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Semi-join operation has some degree of commutability with inner join
+  operation: we can join subquery's tables with ouside table(s) and eliminate
+  duplicate record combination after that:
+
+    ot1 JOIN ot2 SEMI_JOIN{it1,it2} (it1 JOIN it2) ON sjcond(ot2,it*) ->
+              |
+              +-------------------------------+
+                                              v
+    ot1 SEMI_JOIN{it1,it2} (it1 JOIN it2 JOIN ot2) ON sjcond(ot2,it*)
+ 
+  In order for this to work, subquery's top-level operation must be join, and
+  grouping or ordering with limit (grouping or ordering with limit are not
+  commutative with duplicate removal). In other words, the conversion is
+  possible when the subquery doesn't have GROUP BY clause, any aggregate
+  functions*, or ORDER BY ... LIMIT clause.
+
+  Definitions:
+  - Subquery whose top-level operation is a join is called *mergeable semi-join*
+  - All other kinds of semi-join subqueries are considered non-mergeable.
+
+  *- this requirement is actually too strong, but its exceptions are too
+  complicated to be considered here.
+
+  3. Code-level view of semi-join processing
+  ------------------------------------------
+  
+  3.1 Conversion and pre-optimization data structures
+  ---------------------------------------------------
+  * When doing JOIN::prepare for the subquery, we detect that it can be
+    converted into a semi-join and register it in parent_join->sj_subselects
+
+  * At the start of parent_join->optimize(), the predicate is converted into 
+    a semi-join node. A semi-join node is a TABLE_LIST object that is linked
+    somewhere in parent_join->join_list (either it is just present there, or
+    it is a descendant of some of its members).
+  
+  There are two kinds of semi-joins:
+  - Merged semi-joins
+  - Non-merged semi-joins
+   
+  3.1.1 Merged semi-join TABLE_LIST object
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Merged semi-join object is a TABLE_LIST that contains a sub-join of 
+  subquery tables and the semi-join ON expression (in this respect it is 
+  very similar to nested outer join representation)
+  Merged semi-join represents this SQL:
+
+    ... SEMI JOIN (inner_tbl1 JOIN ... JOIN inner_tbl_n) ON sj_on_expr
+  
+  Semi-join objects of this kind have TABLE_LIST::sj_subq_pred set.
+ 
+  3.1.2 Non-merged semi-join data structure
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Non-merged semi-join object is a leaf TABLE_LIST object that has a subquery
+  that produces rows. It is similar to a base table and represents this SQL:
+    
+    ... SEMI_JOIN (SELECT non_mergeable_select) ON sj_on_expr
+  
+  Subquery items that were converted into semi-joins are removed from the WHERE
+  clause. (They do remain in PS-saved WHERE clause, and they replace themselves
+  with Item_int(1) on subsequent re-executions).
+
+  3.2 Semi-joins and join optimization
+  ------------------------------------
+  
+  3.2.1 Non-merged semi-joins and join optimization
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  For join optimization purposes, non-merged semi-join nests are similar to
+  base tables. Each such nest is represented by one one JOIN_TAB, which has 
+  two possible access strategies:
+   - full table scan (representing SJ-Materialization-Scan strategy)
+   - eq_ref-like table lookup (representing SJ-Materialization-Lookup)
+
+  Unlike regular base tables, non-merged semi-joins have:
+   - non-zero JOIN_TAB::startup_cost, and
+   - join_tab->table->is_filled_at_execution()==TRUE, which means one
+     cannot do const table detection, range analysis or other dataset-dependent
+     optimizations.
+     Instead, get_delayed_table_estimates() will run optimization for the
+     subquery and produce an E(materialized table size).
+  
+  3.2.2 Merged semi-joins and join optimization
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+   - optimize_semijoin_nests() does pre-optimization 
+   - during join optimization, the join has one JOIN_TAB (or is it POSITION?) 
+     array, and suffix-based detection is used, see advance_sj_state()
+   - after join optimization is done, get_best_combination() switches 
+     the data-structure to prefix-based, multiple JOIN_TAB ranges format.
+
+  3.3 Semi-joins and query execution
+  ----------------------------------
+  * Join executor has hooks for all semi-join strategies.
+    TODO elaborate.

+EqualityPropagationAndSjmNests
+******************************
+
+Equalities are used for:
+P1. Equality propagation 
+P2. Equality substitution [for a certain join order]
+
+The equality propagation is not affected by SJM nests. In fact, it is done 
+before we determine the execution plan, i.e. before we even know we will use
+SJM-nests for execution.
+
+The equality substitution is affected. 
+
+Substitution without SJMs
+=========================
+When one doesn't have SJM nests, tables have a strict join order:
+
+  ---------------------------------> 
+    t1 -- t2 -- t3 -- t4 --- t5 
+
+
+       ?  ^
+           \
+            --(part-of-WHERE)
+
+
+parts WHERE/ON and ref. expressions are attached at some point along the axis.
+Expression is allowed to refer to a table column if the table is to the left of
+the attachment point. For any given expression, we have a goal: 
+
+  "Move leftmost allowed attachment point as much as possible to the left"
+
+Substitution with SJMs - task setting
+=====================================
+
+When SJM nests are present, there is no global strict table ordering anymore:
+
+   
+  ---------------------------------> 
+
+    ot1 -- ot2 --- sjm -- ot4 --- ot5 
+                   |
+                   |                Main execution
+   - - - - - - - - - - - - - - - - - - - - - - - -                 
+                   |                 Materialization
+      it1 -- it2 --/    
+
+
+Besides that, we must take into account that
+ - values for outer table columns, otN.col, are inaccessible at
+   materialization step                                           (SJM-RULE)
+ - values for inner table columns, itN.col, are inaccessible at Main execution
+   step, except for SJ-Materialization-Scan and columns that are in the 
+   subquery's select list.                                        (SJM-RULE)
+
+Substitution with SJMs - solution
+=================================
+
+First, we introduce global strict table ordering like this:
+
+  ot1 - ot2 --\                    /--- ot3 -- ot5 
+               \--- it1 --- it2 --/
+
+Now, let's see how to meet (SJM-RULE).
+
+SJ-Materialization is only applicable for uncorrelated subqueries. From this, it
+follows that any multiple equality will either
+1. include only columns of outer tables, or
+2. include only columns of inner tables, or
+3. include columns of inner and outer tables, joined together through one 
+   of IN-equalities.
+
+Cases #1 and #2 can be handled in the same way as with regular inner joins.
+
+Case #3 requires special handling, so that we don't construct violations of
+(SJM-RULE). Let's consider possible ways to build violations.
+
+Equality propagation starts with the clause in this form
+
+   top_query_where AND subquery_where AND in_equalities
+
+First, it builds multi-equalities. It can also build a mixed multi-equality
+
+  multiple-equal(ot1.col, ot2.col, ... it1.col, itN.col) 
+
+Multi-equalities are pushed down the OR-clauses in top_query_where and in
+subquery_where, so it's possible that clauses like this one are built:
+
+   subquery_cond OR (multiple-equal(it1.col, ot1.col,...) AND ...)
+   ^^^^^^^^^^^^^                                 \
+         |                                        this must be evaluated
+         \- can only be evaluated                 at the main phase.
+            at the materialization phase
+
+Finally, equality substitution is started. It does two operations:
+
+
+1. Field reference substitution 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+(In the code, this is Item_field::replace_equal_field)
+
+This is a process of replacing each reference to "tblX.col" 
+with the first element of the multi-equality.          (REF-SUBST-ORIG)
+
+This behaviour can cause problems with Semi-join nests. Suppose, we have a
+condition: 
+
+  func(it1.col, it2.col)
+
+and a multi-equality(ot1.col, it1.col). Then, reference to "it1.col" will be 
+replaced with "ot1.col", constructing a condition
+   
+   func(ot1.col, it2.col)
+
+which will be a violation of (SJM-RULE).
+
+In order to avoid this, (REF-SUBST-ORIG) is amended as follows: 
+
+- references to tables "itX.col" that are inner wrt some SJM nest, are
+  replaced with references to the first inner table from the same SJM nest.
+
+- references to top-level tables "otX.col" are replaced with references to
+  the first element of the multi-equality, no matter if that first element is
+  a column of a top-level table or of table from some SJM nest.
+                                                              (REF-SUBST-SJM)
+
+  The case where the first element is a table from an SJM nest $SJM is ok, 
+  because it can be proven that $SJM uses SJ-Materialization-Scan, and 
+  "unpacks" correct column values to the first element during the main
+  execution phase.
+
+2. Item_equal elimination
+~~~~~~~~~~~~~~~~~~~~~~~~~
+(In the code: eliminate_item_equal) This is a process of taking 
+
+  multiple-equal(a,b,c,d,e)
+
+and replacing it with an equivalent expression which is an AND of pair-wise 
+equalities:
+
+  a=b AND a=c AND ...
+
+The equalities are picked such that for any given join prefix (t1,t2...) the
+subset of equalities that can be evaluated gives the most restrictive
+filtering. 
+
+Without SJM nests, it is sufficient to compare every multi-equality member
+with the first one:
+
+  elem1=elem2 AND elem1=elem3 AND elem1=elem4 ... 
+
+When SJM nests are present, we should take care not to construct equalities
+that violate the (SJM-RULE). This is achieved by generating separate sets of
+equalites for top-level tables and for inner tables. That is, for the join
+order 
+
+  ot1 - ot2 --\                    /--- ot3 -- ot5 
+               \--- it1 --- it2 --/
+
+we will generate
+   ot1.col=ot2.col
+   ot1.col=ot3.col
+   ot1.col=ot5.col
+   it2.col=it1.col
+
+
+2.1 The problem with Item_equals and ORs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+As has been mentioned above, multiple equalities are pushed down into OR
+clauses, possibly building clauses like this:
+
+   func(it.col2) OR multiple-equal(it1.col1, it1.col2, ot1.col)      (1)
+
+where the first part of the clause has references to inner tables, while the
+second has references to the top-level tables, which is a violation of
+(SJM-RULE).
+
+AND-clauses of this kind do not create problems, because make_cond_for_table()
+will take them apart. OR-clauses will not be split. It is possible to
+split-out the part that's dependent on the inner table:
+
+   func(it.col2) OR it1.col1=it1.col2
+
+but this is a less-restrictive condition than condition (1). Current execution
+scheme will still try to generate the "remainder" condition:
+
+   func(it.col2) OR it1.col1=ot1.col
+
+which is a violation of (SJM-RULE).
+
+QQ: "ot1.col=it1.col" is checked at the upper level. Why was it not removed
+here?
+AA: because has a proper subset of conditions that are found on this level.
+    consider a join order of  ot, sjm(it)
+    and a condition
+      ot.col=it.col AND ( ot.col=it.col='foo' OR it.col2='bar')
+
+    we will produce: 
+       table ot:  nothing
+       table it:  ot.col=it.col AND (ot.col='foo' OR it.col2='bar')
+                                     ^^^^        ^^^^^^^^^^^^^^^^       
+                                      |          \ the problem is that 
+                                      |            this part condition didnt
+                                      |            receive a substitution
+                                      |
+                                      +--- it was correct to subst, 'ot' is 
+                                           the left-most.
+
+
+Does it make sense to push "inner=outer" down into ORs?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Yes. Consider the query:
+
+  select * from ot 
+  where ot.col in (select it.col from it where (it.col='foo' OR it.col='bar'))
+
+here, it may be useful to infer that 
+
+   (ot.col='foo' OR ot.col='bar')       (CASE-FOR-SUBST)
+
+and attach that condition to the table 'ot'.
+
+Possible solutions for Item_equals and ORs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Solution #1
+~~~~~~~~~~~
+Let make_cond_for_table() chop analyze the OR clauses it has produced and
+discard them if they violate (SJM-RULE). This solution would allow to handle
+cases like (CASE-FOR-SUBST) at the expense of making semantics of
+make_cond_for_table() complicated.
+
+Solution #2
+~~~~~~~~~~~
+Before the equality propagation phase, none of the OR clauses violate the
+(SJM-RULE). This way, if we remember which tables the original equality
+referred to, we can only generate equalities that refer to the outer (or inner)
+tables. Note that this will disallow handling of cases like (CASE-FOR-SUBST).
+
+Currently, solution #2 is implemented.

+                                materialization and scan the materialized table.
+
+  @retval TRUE   If subquery types allow materialization.
+  @retval FALSE  Otherwise.
+
+  @details
+    This is a temporary fix for BUG#36752.
+    
+    There are two subquery materialization strategies:
+
+    1. Materialize and do index lookups in the materialized table. See 
+       BUG#36752 for description of restrictions we need to put on the
+       compared expressions.
+
+    2. Materialize and then do a full scan of the materialized table. At the
+       moment, this strategy's applicability criteria are even stricter than
+       in #1.
+
+       This is so because of the following: consider an uncorrelated subquery
+       
+       ...WHERE (ot1.col1, ot2.col2 ...) IN (SELECT ie1,ie2,... FROM it1 ...)
+
+       and a join order that could be used to do sjm-materialization: 
+          
+          SJM-Scan(it1, it1), ot1, ot2
+       
+       IN-equalities will be parts of conditions attached to the outer tables:
+
+         ot1:  ot1.col1 = ie1 AND ... (C1)
+         ot2:  ot1.col2 = ie2 AND ... (C2)
+       
+       besides those there may be additional references to ie1 and ie2
+       generated by equality propagation. The problem with evaluating C1 and
+       C2 is that ie{1,2} refer to subquery tables' columns, while we only have 
+       current value of materialization temptable. Our solution is to 
+        * require that all ie{N} are table column references. This allows 
+          to copy the values of materialization temptable columns to the
+          original table's columns (see setup_sj_materialization for more
+          details)
+        * require that compared columns have exactly the same type. This is
+          a temporary measure to avoid BUG#36752-type problems.

+  Convert semi-join subquery predicates into semi-join join nests
+
+  SYNOPSIS
+    convert_join_subqueries_to_semijoins()
+ 
+  DESCRIPTION
+
+    Convert candidate subquery predicates into semi-join join nests. This 
+    transformation is performed once in query lifetime and is irreversible.
+    
+    Conversion of one subquery predicate
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+    We start with a join that has a semi-join subquery:
+
+      SELECT ...
+      FROM ot, ...
+      WHERE oe IN (SELECT ie FROM it1 ... itN WHERE subq_where) AND outer_where
+
+    and convert it into a semi-join nest:
+
+      SELECT ...
+      FROM ot SEMI JOIN (it1 ... itN), ...
+      WHERE outer_where AND subq_where AND oe=ie
+
+    that is, in order to do the conversion, we need to 
+
+     * Create the "SEMI JOIN (it1 .. itN)" part and add it into the parent
+       query's FROM structure.
+     * Add "AND subq_where AND oe=ie" into parent query's WHERE (or ON if
+       the subquery predicate was in an ON expression)
+     * Remove the subquery predicate from the parent query's WHERE
+
+    Considerations when converting many predicates
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+    A join may have at most MAX_TABLES tables. This may prevent us from
+    flattening all subqueries when the total number of tables in parent and
+    child selects exceeds MAX_TABLES.
+    We deal with this problem by flattening children's subqueries first and
+    then using a heuristic rule to determine each subquery predicate's
+    "priority".

+  RETURN 
+    FALSE  OK

+  Pull tables out of semi-join nests, if possible
+
+  SYNOPSIS
+    pull_out_semijoin_tables()
+      join  The join where to do the semi-join flattening
+
+  DESCRIPTION
+    Try to pull tables out of semi-join nests.
+     
+    PRECONDITIONS
+    When this function is called, the join may have several semi-join nests
+    but it is guaranteed that one semi-join nest does not contain another.
+   
+    ACTION
+    A table can be pulled out of the semi-join nest if
+     - It is a constant table, or
+     - It is accessed via eq_ref(outer_tables)
+
+    POSTCONDITIONS
+     * Tables that were pulled out have JOIN_TAB::emb_sj_nest == NULL
+     * Tables that were not pulled out have JOIN_TAB::emb_sj_nest pointing 
+       to semi-join nest they are in.
+     * Semi-join nests' TABLE_LIST::sj_inner_tables is updated accordingly
+
+    This operation is (and should be) performed at each PS execution since
+    tables may become/cease to be constant across PS reexecutions.
+    
+  NOTE
+    Table pullout may make uncorrelated subquery correlated. Consider this
+    example:
+    
+     ... WHERE oe IN (SELECT it1.primary_key WHERE p(it1, it2) ... ) 
+    
+    here table it1 can be pulled out (we have it1.primary_key=oe which gives
+    us functional dependency). Once it1 is pulled out, all references to it1
+    from p(it1, it2) become references to outside of the subquery and thus
+    make the subquery (i.e. its semi-join nest) correlated.
+    Making the subquery (i.e. its semi-join nest) correlated prevents us from
+    using Materialization or LooseScan to execute it. 
+
+  RETURN 
+    0 - OK
+    1 - Out of memory error

+  Fix semi-join strategies for the picked join order
+
+  SYNOPSIS
+    fix_semijoin_strategies_for_picked_join_order()
+      join  The join with the picked join order
+
+  DESCRIPTION
+    Fix semi-join strategies for the picked join order. This is a step that
+    needs to be done right after we have fixed the join order. What we do
+    here is switch join's semi-join strategy description from backward-based
+    to forwards based.
+    
+    When join optimization is in progress, we re-consider semi-join
+    strategies after we've added another table. Here's an illustration.
+    Suppose the join optimization is underway:
+
+    1) ot1  it1  it2 
+                 sjX  -- looking at (ot1, it1, it2) join prefix, we decide
+                         to use semi-join strategy sjX.
+
+    2) ot1  it1  it2  ot2 
+                 sjX  sjY -- Having added table ot2, we now may consider
+                             another semi-join strategy and decide to use a 
+                             different strategy sjY. Note that the record
+                             of sjX has remained under it2. That is
+                             necessary because we need to be able to get
+                             back to (ot1, it1, it2) join prefix.
+      what makes things even worse is that there are cases where the choice
+      of sjY changes the way we should access it2. 
+
+    3) [ot1  it1  it2  ot2  ot3]
+                  sjX  sjY  -- This means that after join optimization is
+                               finished, semi-join info should be read
+                               right-to-left (while nearly all plan refinement
+                               functions, EXPLAIN, etc proceed from left to 
+                               right)
+
+    This function does the needed reversal, making it possible to read the
+    join and semi-join order from left to right.

+
+      EXAMPLE
+
+      Consider the query:
+        SELECT * FROM ot WHERE ot.col1 IN (SELECT it.col2 FROM it)
+      
+      Suppose it's executed with SJ-Materialization-scan. We choose to do scan

+        table    access method      condition
+         it      materialize+scan    -
+         ot      (whatever)          ot1.col1=it.col2 (C2)
+
+      The condition C2 refers to current row of table it. The problem is
+      that by the time we evaluate C2, we would have finished with scanning
+      it itself and will be scanning the temptable. 
+
+      At the moment, our solution is to copy back: when we get the next
+      temptable record, we copy its columns to their corresponding columns
+      in the record buffers for the source tables.

+  SYNOPSIS
+    setup_semijoin_dups_elimination()
+      join           Join to process
+      options        Join options (needed to see if join buffering will be 
+                     used or not)
+      no_jbuf_after  Another bit of information re where join buffering will
+                     be used.
+
+  DESCRIPTION
+    Setup the strategies to eliminate semi-join duplicates. ATM there are 4
+    strategies:
+
+    1. DuplicateWeedout (use of temptable to remove duplicates based on rowids
+                         of row combinations)
+    2. FirstMatch (pick only the 1st matching row combination of inner tables)
+    3. LooseScan (scanning the sj-inner table in a way that groups duplicates
+                  together and picking the 1st one)
+    4. SJ-Materialization.
+    
+    The join order has "duplicate-generating ranges", and every range is
+    served by one strategy or a combination of FirstMatch with with some
+    other strategy.
+    
+    "Duplicate-generating range" is defined as a range within the join order
+    that contains all of the inner tables of a semi-join. All ranges must be
+    disjoint, if tables of several semi-joins are interleaved, then the ranges
+    are joined together, which is equivalent to converting
+      SELECT ... WHERE oe1 IN (SELECT ie1 ...) AND oe2 IN (SELECT ie2 )
+    to
+      SELECT ... WHERE (oe1, oe2) IN (SELECT ie1, ie2 ... ...)
+    .
+
+    Applicability conditions are as follows:
+
+    DuplicateWeedout strategy
+    ~~~~~~~~~~~~~~~~~~~~~~~~~
+
+      (ot|nt)*  [ it ((it|ot|nt)* (it|ot))]  (nt)*

+        (1)                 (2)               (3)
+
+       (1) - Prefix of OuterTables (those that participate in 
+             IN-equality and/or are correlated with subquery) and outer 
+             Non-correlated tables.
+       (2) - The handled range. The range starts with the first sj-inner
+             table, and covers all sj-inner and outer tables 
+             Within the range,  Inner, Outer, outer non-correlated tables
+             may follow in any order.
+       (3) - The suffix of outer non-correlated tables.

+      (1) - Prefix of outer and non-correlated tables
+      (2) - The handled range, which may contain only inner and
+            non-correlated tables.
+      (3) - The suffix of outer non-correlated tables.
+
+    LooseScan strategy 
+    ~~~~~~~~~~~~~~~~~~
+
+     (ot|ct|nt) [ loosescan_tbl (ot|nt|it)* it ]  (ot|nt)*

+        (1)           (2)          (3)              (4)
+     
+      (1) - Prefix that may contain any outer tables. The prefix must contain
+            all the non-trivially correlated outer tables. (non-trivially means
+            that the correlation is not just through the IN-equality).
+      
+      (2) - Inner table for which the LooseScan scan is performed.
+
+      (3) - The remainder of the duplicate-generating range. It is served by 
+            application of FirstMatch strategy, with the exception that
+            outer IN-correlated tables are considered to be non-correlated.
+
+      (4) - THe suffix of outer and outer non-correlated tables.
+
+  
+  The choice between the strategies is made by the join optimizer (see
+  advance_sj_state() and fix_semijoin_strategies_for_picked_join_order()).
+  This function sets up all fields/structures/etc needed for execution except
+  for setup/initialization of semi-join materialization which is done in

+    FD_q's (A) is set initially from RL's (A): FD_q.(A) := RL.(A).
+    It's necessary to adjust FD_q.(A) at this point because in the following
+    course FD_q is going to be dumped to RL.
+    Generally FD_q is derived from a received FD_m (roughly FD_q := FD_m) 
+    in queue_event and the master's (A) is installed.
+    At one step with the assignment the Relay-Log's checksum alg is set to 
+    a new value: RL.(A) := FD_q.(A). If the slave service is stopped
+    the last time assigned RL.(A) will be passed over to the restarting
+    service (to the current execution point).
+    RL.A is a "codec" to verify checksum in queue_event() almost all the time
+    the first fake Rotate event.
+    Starting from this point IO thread will executes the following checksum
+    warmup sequence  of actions:
+
+    FD_q.A := RL.A,
+    A_m^0 := master.@@global.binlog_checksum,
+    {queue_event(R_f): verifies(R_f, A_m^0)},

+                        FD_q := FD_m, RL.A := FD_q.A)}
+
+    See legends definition on MYSQL_BIN_LOG::relay_log_checksum_alg
+    docs lines (binlog.h).
+    In above A_m^0 - the value of master's
+    @@binlog_checksum determined in the upcoming handshake (stored in
+    mi->checksum_alg_before_fd).
+
+
+    After the warm-up sequence IO gets to "normal" checksum verification mode
+    to use RL.A in 
+    
+    {queue_event(E_m): verifies(E_m, RL.A)}

+  @brief
+  Merge a derived table/view into the embedding select
+
+  @param thd     thread handle
+  @param lex     LEX of the embedding query.
+  @param derived reference to the derived table.
+
+  @details
+  This function merges the given derived table / view into the parent select
+  construction. Any derived table/reference to view occurred in the FROM
+  clause of the embedding select is represented by a TABLE_LIST structure a
+  pointer to which is passed to the function as in the parameter 'derived'.
+  This structure contains  the number/map, alias, a link to SELECT_LEX of the
+  derived table and other info. If the 'derived' table is used in a nested join
+  then additionally the structure contains a reference to the ON expression
+  for this join.
+
+  The merge process results in elimination of the derived table (or the
+  reference to a view) such that:
+    - the FROM list of the derived table/view is wrapped into a nested join
+      after which the nest is added to the FROM list of the embedding select
+    - the WHERE condition of the derived table (view) is ANDed with the ON
+      condition attached to the table.
+
+  @note
+  Tables are merged into the leaf_tables list, original derived table is removed
+  from this list also. SELECT_LEX::table_list list is left untouched.
+  Where expression is merged with derived table's on_expr and can be found after
+  the merge through the SELECT_LEX::table_list.
+
+  Examples of the derived table/view merge:
+
+  Schema:
+  Tables: t1(f1), t2(f2), t3(f3)
+  View v1: SELECT f1 FROM t1 WHERE f1 < 1
+
+  Example with a view:
+    Before merge:
+
+    The query (Q1): SELECT f1,f2 FROM t2 LEFT JOIN v1 ON f1 = f2
+
+       (LEX of the main query)
+                 |
+           (select_lex)
+                 |
+         (FROM table list)
+                 |
+            (join list)= t2, v1
+                             / \
+                            /  (on_expr)= (f1 = f2)
+                            |
+                    (LEX of the v1 view)
+                            |
+                       (select_lex)= SELECT f1 FROM t1 WHERE f1 < 1
+
+
+    After merge:
+
+    The rewritten query Q1 (Q1'):
+      SELECT f1,f2 FROM t2 LEFT JOIN (t1) ON ((f1 = f2) and (f1 < 1))
+
+        (LEX of the main query)
+                   |

+                                   (on_expr)= (f1 = f2) and (f1 < 1)

-  fill derived table
-
-  SYNOPSIS
-    mysql_derived_filling()
-    thd			Thread handle
-    lex                 LEX for this thread
-    unit                node that contains all SELECT's for derived tables
-    orig_table_list     TABLE_LIST for the upper SELECT
-
-  IMPLEMENTATION
-    Derived table is resolved with temporary table. It is created based on the
-    queries defined. After temporary table is filled, if this is not EXPLAIN,
-    then the entire unit / node is deleted. unit is deleted if UNION is used
-    for derived table and node is deleted is it is a  simple SELECT.
-    If you use this function, make sure it's not called at prepare.
-    Due to evaluation of LIMIT clause it can not be used at prepared stage.
-
-  RETURN
-    FALSE  OK
-    TRUE   Error

+
+  SYNOPSIS
+    create_key_arg_fields()
+
+  DESCRIPTION
+    The function creates descriptors of the record fields stored in the join
+    buffer that are used to build access keys to the joined table. These
+    fields are put into the buffer ahead of other records fields stored in
+    the buffer. Such placement helps to optimize construction of access keys.
+    For each field that is used to build access keys to the joined table but
+    is stored in some other join cache buffer the function saves a pointer
+    to the the field descriptor. The array of such pointers are placed in the
+    the join cache structure just before the array of pointers to the
+    blob fields blob_ptr.
+    Any field stored in a join cache buffer that is used to construct keys
+    to access tables associated with other join caches is called a referenced
+    field. It receives a unique number that is saved by the function in the
+    member 'referenced_field_no' of the CACHE_FIELD descriptor for the field.
+    This number is used as index to the array of offsets to the referenced
+    fields that are saved and put in the join cache buffer after all record
+    fields.
+    The function also finds out whether that the keys to access join_tab
+    can be considered as embedded and, if so, sets the flag 'use_emb_key' in
+    this join cache appropriately. 
+     
+  NOTES.
+    When a key to access the joined table 'join_tab' is constructed the array
+    of pointers to the field descriptors for the external fields is looked
+    through. For each of this pointers we find out in what previous key cache
+    the referenced field is stored. The value of 'referenced_field_no'
+    provides us with the index into the array of offsets for referenced 
+    fields stored in the join cache. The offset read by the the index allows
+    us to read the field without reading all other fields of the record 
+    stored the join cache buffer. This optimizes the construction of keys
+    to access 'join_tab' when some key arguments are stored in the previous
+    join caches.

+  NOTES
+    The function does not do anything if no key is used to join the records

+  SYNOPSIS
+    check_emb_key_usage()
+
+  DESCRIPTION
+    The function checks some conditions at which the key values can be read
+    directly from the join buffer. This is possible when the key values can be
+    composed by concatenation of the record fields stored in the join buffer.
+    Sometimes when the access key is multi-component the function has to re-order
+    the fields written into the join buffer to make keys embedded. If key 
+    values for the key access are detected as embedded then 'use_emb_key'
+    is set to TRUE.
+
+  EXAMPLE
+    Let table t2 has an index defined on the columns a,b . Let's assume also
+    that the columns t2.a, t2.b as well as the columns t1.a, t1.b are all
+    of the integer type. Then if the query
+      SELECT COUNT(*) FROM t1, t2 WHERE t1.a=t2.a and t1.b=t2.b  
+    is executed with a join cache in such a way that t1 is the driving
+    table then the key values to access table t2 can be read directly
+    from the join buffer.
+  
+  NOTES
+    In some cases key values could be read directly from the join buffer but
+    we still do not consider them embedded. In the future we'll expand the
+    the class of keys which we identify as embedded.
+
+  NOTES
+    The function returns FALSE if no key is used to join the records

+
+  DESCRIPTION
+    The functions extends all records from the join buffer by the matched
+    records from join_tab. In the case of outer join operation it also
+    adds null complementing extensions for the records from the join buffer
+    that have no match. 
+    No extensions are generated for the last record from the buffer if
+    skip_last is true.  
+
+  NOTES
+    The function must make sure that if linked join buffers are used then
+    a join buffer cannot be refilled again until all extensions in the
+    buffers chained to this one are generated.
+    Currently an outer join operation with several inner tables always uses
+    at least two linked buffers with the match join flags placed in the
+    first buffer. Any record composed of rows of the inner tables that
+    matches a record in this buffer must refer to the position of the
+    corresponding match flag.
+
+  IMPLEMENTATION
+    When generating extensions for outer tables of an outer join operation
+    first we generate all extensions for those records from the join buffer
+    that have matches, after which null complementing extension for all
+    unmatched records from the join buffer are generated.

+
+  SYNOPSIS
+    join_matching_records()
+      skip_last    do not look for matches for the last partial join record 
+
+  DESCRIPTION
+    The function retrieves rows of the join_tab table and checks whether they
+    match partial join records from the join buffer. If a match is found
+    the function will call the sub_select function trying to look for matches
+    for the remaining join operations.
+    This function currently is called only from the function join_records.    
+    If the value of skip_last is true the function writes the partial join
+    record from the record buffer into the join buffer to save its value for
+    the future processing in the caller function.
+
+  NOTES
+    If employed by BNL or BNLH join algorithms the function performs a full
+    scan of join_tab for each refill of the join buffer. If BKA or BKAH
+    algorithms are used then the function iterates only over those records
+    from join_tab that can be accessed by keys built over records in the join
+    buffer. To apply a proper method of iteration the function just calls
+    virtual iterator methods (open, next, close) of the member join_tab_scan.
+    The member can be either of the JOIN_TAB_SCAN or JOIN_TAB_SCAN_MMR type.
+    The class JOIN_TAB_SCAN provides the iterator methods for BNL/BNLH join
+    algorithms. The class JOIN_TAB_SCAN_MRR provides the iterator methods
+    for BKA/BKAH join algorithms.
+    When the function looks for records from the join buffer that would
+    match a record from join_tab it iterates either over all records in
+    the buffer or only over selected records. If BNL join operation is
+    performed all records are checked for the match. If BNLH or BKAH
+    algorithm is employed to join join_tab then the function looks only
+    through the records with the same join key as the record from join_tab.
+    With the BKA join algorithm only one record from the join buffer is checked
+    for a match for any record from join_tab. To iterate over the candidates
+    for a match the virtual function get_next_candidate_for_match is used,
+    while the virtual function prepare_look_for_matches is called to prepare
+    for such iteration proccess.     
+
+  NOTES
+    The function produces all matching extensions for the records in the 
+    join buffer following the path of the employed blocked algorithm. 
+    When an outer join operation is performed all unmatched records from
+    the join buffer must be extended by null values. The function 
+    'join_null_complements' serves this purpose.

+  NOTES 
+    Accessing columns of the previous tables requires special handling with

+    lookup its previous-records-combination is not in prev_table->record[0]
+    but somewhere in the join buffer.    
+    We need to get it from there back into prev_table(s)->record[0] before we
+    can evaluate the index condition, and that's why we need this function
+    instead of regular IndexConditionPushdown.
+
+  NOTES
+    Possible optimization:
+    Before we unpack the record from a previous table
+    check if this table is used in the condition.
+    If so then unpack the record otherwise skip the unpacking.
+    This should be done by a special virtual method

+  The class JOIN_CACHE_HASHED is the base class for the classes
+  JOIN_CACHE_HASHED_BNL and JOIN_CACHE_HASHED_BKA. The first of them supports
+  an implementation of Block Nested Loop Hash (BNLH) Join Algorithm,
+  while the second is used for a variant of the BKA Join algorithm that performs
+  only one lookup for any records from join buffer with the same key value. 
+  For a join cache of this class the records from the join buffer that have
+  the same access key are linked into a chain attached to a key entry structure
+  that either itself contains the key value, or, in the case when the keys are
+  embedded, refers to its occurrence in one of the records from the chain.
+  To build the chains with the same keys a hash table is employed. It is placed
+  at the very end of the join buffer. The array of hash entries is allocated
+  first at the very bottom of the join buffer, while key entries are placed
+  before this array.
+  A hash entry contains a header of the list of the key entries with the same
+  hash value. 
+  Each key entry is a structure of the following type:
+    struct st_join_cache_key_entry {
+      union { 
+        uchar[] value;
+        cache_ref *value_ref; // offset from the beginning of the buffer
+      } hash_table_key;
+      key_ref next_key; // offset backward from the beginning of hash table
+      cache_ref *last_rec // offset from the beginning of the buffer
+    }
+  The references linking the records in a chain are always placed at the very
+  beginning of the record info stored in the join buffer. The records are 
+  linked in a circular list. A new record is always added to the end of this 
+  list.
+
+  The following picture represents a typical layout for the info stored in the
+  join buffer of a join cache object of the JOIN_CACHE_HASHED class.

+  A base class for in-memory buffer used by DS-MRR implementation. Common
+  properties:
+  - The buffer is last-in-first-out, i.e. elements that are written last are
+    read first.
+  - The buffer contains fixed-size elements. The elements are either atomic
+    byte sequences or pairs of them.
+  - The buffer resides in the memory provided by the user. It is possible to
+     = dynamically (ie. between write operations) add ajacent memory space to
+       the buffer
+     = dynamically remove unused space from the buffer.
+    The intent of this is to allow to have two buffers on adjacent memory
+    space, one is being read from (and so its space shrinks), while the other 
+    is being written to (and so it needs more and more space).
+
+  There are two concrete classes, Forward_lifo_buffer and Backward_lifo_buffer.

-  Remove the predicates pushed down into the subquery
-
-  SYNOPSIS
-    JOIN::remove_subq_pushed_predicates()
-      where   IN  Must be NULL
-              OUT The remaining WHERE condition, or NULL
-
-  DESCRIPTION
-    Given that this join will be executed using (unique|index)_subquery,
-    without "checking NULL", remove the predicates that were pushed down
-    into the subquery.
-
-    If the subquery compares scalar values, we can remove the condition that
-    was wrapped into trig_cond (it will be checked when needed by the subquery
-    engine)
-
-    If the subquery compares row values, we need to keep the wrapped
-    equalities in the WHERE clause: when the left (outer) tuple has both NULL
-    and non-NULL values, we'll do a full table scan and will rely on the
-    equalities corresponding to non-NULL parts of left tuple to filter out
-    non-matching records.
-
-    TODO: We can remove the equalities that will be guaranteed to be true by the
-    fact that subquery engine will be using index lookup. This must be done only
-    for cases where there are no conversion errors of significance, e.g. 257
-    that is searched in a byte. But this requires homogenization of the return 
-    codes of all Field*::store() methods.

-  Index lookup-based subquery: save some flags for EXPLAIN output
-
-  SYNOPSIS
-    save_index_subquery_explain_info()
-      join_tab  Subquery's join tab (there is only one as index lookup is
-                only used for subqueries that are single-table SELECTs)
-      where     Subquery's WHERE clause
-
-  DESCRIPTION
-    For index lookup-based subquery (i.e. one executed with
-    subselect_uniquesubquery_engine or subselect_indexsubquery_engine),
-    check its EXPLAIN output row should contain 
-      "Using index" (TAB_INFO_FULL_SCAN_ON_NULL) 
-      "Using Where" (TAB_INFO_USING_WHERE)
-      "Full scan on NULL key" (TAB_INFO_FULL_SCAN_ON_NULL)
-    and set appropriate flags in join_tab->packed_info.

+  Check whether a join buffer can be used to join the specified table   
+
+  SYNOPSIS
+    check_join_cache_usage()
+      tab                 joined table to check join buffer usage for
+      options             options of the join
+      no_jbuf_after       don't use join buffering after table with this number
+      prev_tab            previous join table
+
+  DESCRIPTION
+    The function finds out whether the table 'tab' can be joined using a join
+    buffer. This check is performed after the best execution plan for 'join'
+    has been chosen. If the function decides that a join buffer can be employed
+    then it selects the most appropriate join cache object that contains this
+    join buffer.
+    The result of the check and the type of the the join buffer to be used
+    depend on:
+      - the access method to access rows of the joined table
+      - whether the join table is an inner table of an outer join or semi-join
+      - whether the optimizer switches
+          outer_join_with_cache, semijoin_with_cache, join_cache_incremental,
+          join_cache_hashed, join_cache_bka,
+        are set on or off
+      - the join cache level set for the query
+      - the join 'options'.
+
+    In any case join buffer is not used if the number of the joined table is
+    greater than 'no_jbuf_after'. It's also never used if the value of
+    join_cache_level is equal to 0.
+    If the optimizer switch outer_join_with_cache is off no join buffer is
+    used for outer join operations.
+    If the optimizer switch semijoin_with_cache is off no join buffer is used
+    for semi-join operations.
+    If the optimizer switch join_cache_incremental is off no incremental join
+    buffers are used.
+    If the optimizer switch join_cache_hashed is off then the optimizer uses
+    neither BNLH algorithm, nor BKAH algorithm to perform join operations.
+
+    If the optimizer switch join_cache_bka is off then the optimizer uses
+    neither BKA algorithm, nor BKAH algorithm to perform join operation.
+    The valid settings for join_cache_level lay in the interval 0..8.
+    If it set to 0 no join buffers are used to perform join operations.
+    Currently we differentiate between join caches of 8 levels:
+      1 : non-incremental join cache used for BNL join algorithm
+      2 : incremental join cache used for BNL join algorithm
+      3 : non-incremental join cache used for BNLH join algorithm
+      4 : incremental join cache used for BNLH join algorithm
+      5 : non-incremental join cache used for BKA join algorithm
+      6 : incremental join cache used for BKA join algorithm 
+      7 : non-incremental join cache used for BKAH join algorithm 
+      8 : incremental join cache used for BKAH join algorithm
+    If the value of join_cache_level is set to n then no join caches of
+    levels higher than n can be employed.
+
+    If the optimizer switches outer_join_with_cache, semijoin_with_cache,
+    join_cache_incremental, join_cache_hashed, join_cache_bka are all on
+    the following rules are applied.
+    If join_cache_level==1|2 then join buffer is used for inner joins, outer
+    joins and semi-joins with 'JT_ALL' access method. In this case a
+    JOIN_CACHE_BNL object is employed.
+    If join_cache_level==3|4 and then join buffer is used for a join operation
+    (inner join, outer join, semi-join) with 'JT_REF'/'JT_EQREF' access method
+    then a JOIN_CACHE_BNLH object is employed. 
+    If an index is used to access rows of the joined table and the value of
+    join_cache_level==5|6 then a JOIN_CACHE_BKA object is employed. 
+    If an index is used to access rows of the joined table and the value of
+    join_cache_level==7|8 then a JOIN_CACHE_BKAH object is employed. 
+    If the value of join_cache_level is odd then creation of a non-linked 
+    join cache is forced.
+
+    Currently for any join operation a join cache of the  level of the
+    highest allowed and applicable level is used.
+    For example, if join_cache_level is set to 6 and the optimizer switch
+    join_cache_bka is off, while the optimizer switch join_cache_hashed is
+    on then for any inner join operation with JT_REF/JT_EQREF access method
+    to the joined table the BNLH join algorithm will be used, while for
+    the table accessed by the JT_ALL methods the BNL algorithm will be used.
+
+    If the function decides that a join buffer can be used to join the table
+    'tab' then it sets the value of tab->use_join_buffer to TRUE and assigns
+    the selected join cache object to the field 'cache' of the previous
+    join table. 
+    If the function creates a join cache object it tries to initialize it. The
+    failure to do this results in an invocation of the function that destructs
+    the created object.
+    If the function decides that but some reasons no join buffer can be used
+    for a table it calls the function revise_cache_usage that checks
+    whether join cache should be denied for some previous tables. In this case
+    a pointer to the first table for which join cache usage has been denied
+    is passed in join->return_val (see the function set_join_cache_denial).
+    
+    The functions changes the value the fields tab->icp_other_tables_ok and
+    tab->idx_cond_fact_out to FALSE if the chosen join cache algorithm 
+    requires it.
+ 
+  NOTES
+    An inner table of a nested outer join or a nested semi-join can be currently
+    joined only when a linked cache object is employed. In these cases setting
+    join_cache_incremental to 'off' results in denial of usage of any join
+    buffer when joining the table.
+    For a nested outer join/semi-join, currently, we either use join buffers for
+    all inner tables or for none of them. 
+    Some engines (e.g. Falcon) currently allow to use only a join cache
+    of the type JOIN_CACHE_BKAH when the joined table is accessed through
+    an index. For these engines setting the value of join_cache_level to 5 or 6
+    results in that no join buffer is used to join the table. 
+  
+  RETURN VALUE
+    cache level if cache is used, otherwise returns 0
+
+  TODO
+    Support BKA inside SJ-Materialization nests. When doing this, we'll need
+    to only store sj-inner tables in the join buffer.

+                          next_linear_tab(join, WITH_CONST_TABLES) order).
+
+  DESCRIPTION
+    For each table after the first non-constant table the function checks
+    whether the table can be joined using a join buffer. If the function decides
+    that a join buffer can be employed then it selects the most appropriate join
+    cache object that contains this join buffer whose level is not greater
+    than join_cache_level set for the join. To make this check the function
+    calls the function check_join_cache_usage for every non-constant table.
+
+  NOTES
+    In some situations (e.g. for nested outer joins, for nested semi-joins) only
+    incremental buffers can be used. If it turns out that for some inner table
+    no join buffer can be used then any inner table of an outer/semi-join nest
+    cannot use join buffer. In the case when already chosen buffer must be

+  IMPLEMENTATION
     The function is implemented by a recursive procedure.  On the recursive
     ascent all attributes are calculated, all outer joins that can be
     converted are replaced and then all unnecessary braces are removed.
     As join list contains join tables in the reverse order sequential
     elimination of outer joins does not require extra recursive calls.
 
+  SEMI-JOIN NOTES
+    Remove all semi-joins that have are within another semi-join (i.e. have

+
+  EXAMPLES
     Here is an example of a join query with invalid cross references:

+  Fill the join buffer with partial records, retrieve all full  matches for them   
+
+  SYNOPSIS
+    sub_select_cache()
+      join     pointer to the structure providing all context info for the query
+      join_tab the first next table of the execution plan to be retrieved
+      end_records  true when we need to perform final steps of the retrieval
+
+  DESCRIPTION
+    For a given table Ti= join_tab from the sequence of tables of the chosen 
+    execution plan T1,...,Ti,...,Tn the function just put the partial record
+    t1,...,t[i-1] into the join buffer associated with table Ti unless this
+    is the last record added into the buffer. In this case,  the function 
+    additionally finds all matching full records for all partial
+    records accumulated in the buffer, after which it cleans the buffer up.
+    If a partial join record t1,...,ti is extended utilizing a dynamic
+    range scan then it is not put into the join buffer. Rather all matching
+    records are found for it at once by the function sub_select.
+
+  NOTES
+    The function implements the algorithmic schema for both Blocked Nested
+    Loop Join and Batched Key Access Join. The difference can be seen only at
+    the level of of the implementation of the put_record and join_records

+  SYNOPSIS
+    cmp_buffer_with_ref()
+      tab      Join tab of the accessed table
+      table    The table to read.  This is usually tab->table, except for 
+               semi-join when we might need to make a lookup in a temptable
+               instead.
+      tab_ref  The structure with methods to collect index lookup tuple. 
+               This is usually table->ref, except for the case of when we're 
+               doing lookup into semi-join materialization table.
+
+  DESCRIPTION 
+    Used by eq_ref access method: create the index lookup key and check if 
+    we've used this key at previous lookup (If yes, we don't need to repeat
+    the lookup - the record has been already fetched)
 
+  RETURN 
+    TRUE   No cached record for the key, or failed to create the key (due to
+           out-of-domain error)
+    FALSE  The created key is the same as the previous one (and the record 
+           is already in table->record)

+     that are about to be injected into the query.
+  2. Expand if necessary the original KEYUSE array JOIN::keyuse to

-   Replace all views that only use one table with the table itself.  This
-   allows us to treat the view as a simple table and even update it (it is a
-   kind of optimization).
+  @brief
+  Create field translation for mergeable derived table/view.
 
-   @note 
+  @param thd  Thread handle
 
-   This optimization is potentially dangerous as it makes views
-   masquerade as base tables: Views don't have the pointer TABLE_LIST::table
-   set to non-@c NULL.
+  @details
+  Create field translation for mergeable derived table/view.
 
-   We may have the case where a view accesses tables not normally accessible
-   in the current Security_context (only in the definer's
-   Security_context). According to the table's GRANT_INFO (TABLE::grant),
-   access is fulfilled, but this is implicitly meant in the definer's security
-   context. Hence we must never look at only a TABLE's GRANT_INFO without
-   looking at the one of the referring TABLE_LIST.

-  There is one problem with aliases for command-line options.
-  Plugin initialization works like this
-
-     for all plugins:
-       prepare command-line options
-       initialize command-line option variables to the default values
-       parse command line, assign values as necessary
-
-     for all plugins:
-       call the plugin initialization function
-
-  it means, we cannot have maria* and aria* command-line options to use
-  the same underlying variables - because after assigning maria* values,
-  MySQL will put there default values again preparing for parsing aria*
-  values. So, maria* values will be lost.
-
-  So, we create separate set of variables for maria* options,
-  and take both values into account in ha_maria_init().
-
-  When the command line was parsed, we patch maria* options
-  to use the same variables as aria* options so that
-  set @@maria_some_var would have the same value as @@aria_some_var
-  without forcing us to copy the values around all the time.
