+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

-   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."

-  Skip trailing space.
-
-  On most systems reading memory in larger chunks (ideally equal to the size of
-  the chinks that the machine physically reads from memory) causes fewer memory
-  access loops and hence increased performance.
-  This is why the 'int' type is used : it's closest to that (according to how
-  it's defined in C).
-  So when we determine the amount of whitespace at the end of a string we do
-  the following :
-    1. We divide the string into 3 zones :
-      a) from the start of the string (__start) to the first multiple
-        of sizeof(int)  (__start_words)
-      b) from the end of the string (__end) to the last multiple of sizeof(int)
-        (__end_words)
-      c) a zone that is aligned to sizeof(int) and can be safely accessed
-        through an int *
-    2. We start comparing backwards from (c) char-by-char. If all we find is
-       space then we continue
-    3. If there are elements in zone (b) we compare them as unsigned ints to a
-       int mask (SPACE_INT) consisting of all spaces
-    4. Finally we compare the remaining part (a) of the string char by char.
-       This covers for the last non-space unsigned int from 3. (if any)
-
-   This algorithm works well for relatively larger strings, but it will slow
-   the things down for smaller strings (because of the additional calculations
-   and checks compared to the naive method). Thus the barrier of length 20
-   is added.
-
-   @param     ptr   pointer to the input string
-   @param     len   the length of the string
-   @return          the last non-space character

+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.

+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

+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:
+

+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.
+

+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

+=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 file in your home directory (C<~/.mytop>). If present,
+B<mytop> will read it automatically. It is 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.

+     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).

+
+   - Data is stored together with the primary key (no secondary lookup

+
+   All the above is usually true for engines that store the row
+   data in the primary key index (e.g. in a b-tree), and use the primary

-    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.

+      join order, so it's not possible for SJ-Mat to be
+      SJ-Materialization-lookup, it is SJ-Materialization-Scan. The scan part
+      of this strategy will unpack value of it1.col=it2.col into it1.col

-  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     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

+  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.
 
-  bool use_default_impl; /* TRUE <=> shortcut all calls to default MRR impl */
+  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

+  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.

-    This does the following:

-       = (t_1||...||t_k||new_tree)
-     or
-       = (t_1||....||(t_j|| new_tree)||...||t_k),
-
-     where t_i, y are SEL_TREEs.
-    new_tree is combined with the first t_j it has a SEL_ARG on common
-    key with. As a consequence of this, choice of keys to do index_merge
-    read may depend on the order of conditions in WHERE part of the query.
+  DESCRIPTION
+    The function checks whether there is any range tree rt_i in this imerge

+    rt_i and the range part of the SEL_TREE tree.  
+    To check this the function calls the function sel_trees_have_common_keys.

+      is_last_check_pass OUT <=> no more calls of the function for this imerge
+
+  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), but not must 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.
+
+    When is_first_check==TRUE the function returns FALSE in the parameter
+    is_last_check_pass if there is no rt_j such that rt_j can be ored with rt,
+    but, at the same time, it's not true that rt_j must be ored with rt.
+    When is_first_check==FALSE the function always returns FALSE in the
+    parameter is_last_check_pass.    
+          
+  RETURN
+    1  The result of oring of rt_j and rt that must be ored returns the
+       the range tree with type==SEL_TREE::ALWAYS
+       (in this case the imerge m should be discarded)
+   -1  The function runs out of memory

+      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.
+
+    The imerges that the operation produces replace those in the list im1   
+

-  Perform OR operation on index_merge list and key tree.
+  Perform OR operation for each imerge from a list and the range part of a tree
 
+  SYNOPSIS
+    imerge_list_or_tree()
+      param       Context info for the operation
+      merges      The list of imerges to be ored with the range part of tree          
+      tree        SEL_TREE whose range part is to be ored with the imerges
+
+  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
+    1     if no imerges are produced
+    0     otherwise

+
+  DESCRIPTION
+    For each imerge from the list merges the function pushes the range part

+    More exactly if the imerge mi from the list represents the formula

+    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

+      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.

+  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.

+    number of records in the partial intersection curr. In this case the

+    If the function cannot expect that the number of records in the extended

+  DESCRIPTION
+    This function takes range parts of two trees tree1 and tree2 and builds
+    a range tree for the conjunction of the formulas that these two range parts
+    represent.
+    More exactly: 
+    if the range part of tree1 represents the normalized formula 
+      R1_1 AND ... AND R1_k,
+    and the range part of tree2 represents the normalized formula
+      R2_1 AND ... AND R2_k,
+    then the range part of the result represents the formula:
+     RT = R_1 AND ... AND R_k, where R_i=(R1_i AND R2_i) for each i from [1..k]
+
+    The function assumes that tree1 is never equal to tree2. At the same
+    time the tree result can be the same as tree1 (but never as tree2).
+    If result==tree1 then rt replaces the range part of tree1 leaving
+    imerges as they are.

+      tree1           SEL_TREE for the first 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 MT1 AND MT2 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)
+
+  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
+    possible index merge plans are evaluated. If after this removal one
+    of the range trees in the index merge becomes empty the whole index merge
+    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
+    0 - otherwise

+  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 - they've got one JOIN_TAB, which can be accessed with one of
+  two methods:
+   - 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 or range analysis or other table data-
+     dependent inferences
+  // instead, get_delayed_table_estimates() runs optimization on the nest so that 
+  // we get an idea about temptable 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.

+    Get #output_rows and scan_time estimates for a "delayed" table. By

+    get #rows estimate for it, it has to call this function instead.
+
+    This function is expected to make different actions depending on the nature

+  1. compute materialize_strategy_cost based on the unmodified subquery

+  3. compute in_exists_strategy_cost based on the reoptimized plan

+       revert the subquery plan to the original one before reoptimizing
+     else
+       inject the IN=>EXISTS predicates into the new EXISTS subquery plan
+
+  The implementation itself is a bit more complicated because it takes into

+  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)

-
-  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.

+
+  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.

+                        the estimated number of records in the partial join 
 
   DESCRIPTION
-    The function initializes the cache structure. It supposed to be called
-    right after a constructor for the JOIN_CACHE_BNL.
-    The function allocates memory for the join buffer and for descriptors of
-    the record fields stored in the buffer.
+    At the first its invocation for the cache the function calculates the
+    maximum possible size of join buffer for the cache. If the parameter
+    optimize_buff_size true then this value does not exceed the size of the
+    space needed for the estimated number of records 'max_records' in the
+    partial join that joins tables from the first one through join_tab. This
+    value is also capped off by the value of join_tab->join_buffer_size_limit,
+    if it has been set a to non-zero value, and by the value of the system
+    parameter join_buffer_size - otherwise. After the calculation of the
+    interesting size the function saves the value in the field 'max_buff_size'
+    in order to use it directly at the next  invocations of the function.
 
   NOTES
-    The code of this function should have been included into the constructor
-    code itself. However the new operator for the class JOIN_CACHE_BNL would
-    never fail while memory allocation for the join buffer is not absolutely
-    unlikely to fail. That's why this memory allocation has to be placed in a
-    separate function that is called in a couple with a cache constructor.
-    It is quite natural to put almost all other constructor actions into
-    this function.     
-

+    The function allocates a lump of memory for the cache join buffer. 
+    Initially the function sets the size of the buffer buff_size equal to

+    the space intended to be used for the join buffers employed by the

+    to shrink the used buffers to make the occupied space fit the maximum
+    memory allowed to be used for all join buffers in total. After
+    this the function tries to allocate a join buffer for join_tab.
+    If it fails to do so, it decrements the requested size of the join
+    buffer, shrinks proportionally the join buffers used for the previous
+    tables and tries to allocate a buffer for join_tab. In the case of a
+    failure the function repeats its attempts with smaller and smaller
+    requested sizes of the buffer, but not more than 4 times.

-  DESCRIPTION
-    This function is invoked from MRR implementation to check if an index
-    tuple matches the index condition. It is used in the case where the index
-    condition actually depends on both columns of the used index and columns
-    from previous tables.
-    
-    Accessing columns of the previous tables requires special handling with
-    BKA. The idea of BKA is to collect record combinations in a buffer and 
-    then do a batch of ref access lookups, i.e. by the time we're doing a
-    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.
-
-  NOTE
-    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

+}
 
-  NOTES
-    The function produces all matching extensions for the records in the 
-    join buffer following the path of the Batched Key Access 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.
-    The Batched Key Access algorithm assumes that key accesses are batched.
-    In other words it assumes that, first, either keys themselves or the
-    corresponding rowids (primary keys) are accumulated in a buffer, then
-    data rows from  join_tab are fetched for all of them. When a row is
-    fetched it is always returned with a reference to the key by which it
-    has been accessed.
-    When key values are batched we can save on the number of the server 
-    requests for index lookups. For the remote engines, like NDB cluster, it
-    essentially reduces the number of round trips between the server and
-    the engine when performing a join operation. 
-    When the rowids for the keys are batched we can optimize the order
-    in what we fetch the data for this rowids. The performance benefits of
-    this optimization can be significant for such engines as MyISAM, InnoDB.
-    What is exactly batched are hidden behind implementations of
-    MRR handler interface that is supposed to be appropriately chosen
-    for each engine. If for a engine no specific implementation of the MRR
-    interface is supllied then the default implementation is used. This
-    implementation actually follows the path of Nested Loops Join algorithm.
-    In this case BKA join surely will demonstrate a worse performance than
-    NL join.

-  DESCRIPTION
-    The function reads key fields from the current record in the join buffer.
-    and builds the key value out of these fields that will be used to access
-    the 'join_tab' table. Some of key fields may belong to previous caches.
-    They are accessed via record references to the record parts stored in the
-    previous join buffers. The other key fields always are placed right after
-    the flag fields of the record.
-    If the key is embedded, which means that its value can be read directly
-    from the join buffer, then *key is set to the beginning of the key in
-    this buffer. Otherwise the key is built in the join_tab->ref->key_buff.
-    The function returns the length of the key if it succeeds ro read it.
-    If is assumed that the functions starts reading at the position of
-    the record length which is provided for each records in a BKA cache.
-    After the key is built the 'pos' value points to the first position after
-    the current record.

   DESCRIPTION
-    The function initializes the cache structure. It supposed to be called

-    The function allocates memory for the join buffer and for descriptors of

+    table to be used and initializes this hash table within the join buffer

-  NOTES
-    The code of this function should have been included into the constructor
-    code itself. However the new operator for the class JOIN_CACHE_BKA_UNIQUE
-    would never fail while memory allocation for the join buffer is not 
-    absolutely unlikely to fail. That's why this memory allocation has to be
-    placed in a separate function that is called in a couple with a cache 
-    constructor.
-    It is quite natural to put almost all other constructor actions into
-    this function.

-    Possible optimization:

   DESCRIPTION
-    This function can be used only when the table join_tab can be accessed
-    by keys built over the fields of previous join tables.
-    The function retrieves all keys from the hash table of the join buffer
-    built for partial join records from the buffer. For each of these keys
-    the function performs an index lookup and tries to match records yielded
-    by this lookup with records from the join buffer attached to the key.
-    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 does not assume that matching records are necessarily
-    returned with references to the keys by which they were found. If the call
-    of the function multi_range_read_init returns flags with
-    HA_MRR_NO_ASSOCIATION then a search for the key built from the returned
-    record is carried on. The search is performed by probing in in the hash
-    table of the join buffer.
-    This function currently is called only from the function join_records.

+
+  SYNOPSIS
+    get_next_key()
+      key    pointer to the buffer where the key value is to be placed
+
+  DESCRIPTION
+    The function reads key fields from the current record in the join buffer.
+    and builds the key value out of these fields that will be used to access
+    the 'join_tab' table. Some of key fields may belong to previous caches.
+    They are accessed via record references to the record parts stored in the
+    previous join buffers. The other key fields always are placed right after
+    the flag fields of the record.
+    If the key is embedded, which means that its value can be read directly
+    from the join buffer, then *key is set to the beginning of the key in
+    this buffer. Otherwise the key is built in the join_tab->ref->key_buff.
+    The function returns the length of the key if it succeeds ro read it.
+    If is assumed that the functions starts reading at the position of
+    the record length which is provided for each records in a BKA cache.
+    After the key is built the 'pos' value points to the first position after
+    the current record.
+    The function just skips the records with MATCH_IMPOSSIBLE in the
+    match flag field if there is any. 
+    The function returns 0 if the initial position is after the beginning
+    of the record fields for last record from the join buffer. 
+
+  RETURN VALUE

+    
+  DESCRIPTION
+    This function is invoked from MRR implementation to check if an index
+    tuple matches the index condition. It is used in the case where the index
+    condition actually depends on both columns of the used index and columns
+    from previous tables.
+   
+  NOTES 
+    Accessing columns of the previous tables requires special handling with
+    BKA. The idea of BKA is to collect record combinations in a buffer and 
+    then do a batch of ref access lookups, i.e. by the time we're doing a
+    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

+  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

+      key_ref next_key; // offset backward from the beginning of hash table
+      cache_ref *last_rec // offset from the beginning of the buffer
+    }

       - 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

+          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.
-    The other valid settings of join_cache_level lay in the interval 1..8.
-    If join_cache_level==1|2 then join buffer is used only for inner joins
-    with 'JT_ALL' access method.  
-    If join_cache_level==3|4 then join buffer is used for any join operation
-    (inner join, outer join, semi-join) with 'JT_ALL' access method.
-    If 'JT_ALL' access method is used to read rows of the joined table then
-    always a JOIN_CACHE_BNL object is employed.
+    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

+      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_BKA_UNIQUE object is employed. 
+    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.

+    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 level to an odd number results in denial of usage of any join
+    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_BKA_UNIQUE when the joined table is accessed through
+    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.

+
+  SYNOPSIS

+      join                join whose tables are to be checked             
+      options             options of the join
+      no_jbuf_after       don't use join buffering after table with this number
+                          (The tables are assumed to be numbered in
+                          first_linear_tab(join, WITHOUT_CONST_TABLES),
+                          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
+    denied for a table the function recalls check_join_cache_usage()
+    starting from this table. The pointer to the table from which the check
+    has to be restarted is returned in join->return_val (see the description
+    of check_join_cache_usage).

-  DESCRIPTION
-    This is a join execution function that does materialization of a join
-    suborder before joining it to the rest of the join.
-
-    The table pointed by join_tab is the first of the materialized tables.
-    This function first creates the materialized table and then switches to
-    joining the materialized table with the rest of the join.
-
-    The materialized table can be accessed in two ways:
-     - index lookups
-     - full table scan
-
-  RETURN
-    One of enum_nested_loop_state values

-  DESCRIPTION
-    Extract the condition that can be checked after reading the table
-    specified in 'used_table', given that current-field values for tables
-    specified in 'tables' bitmap are available.
-
-    The function assumes that
-      - Constant parts of the condition has already been checked.
-      - Condition that could be checked for tables in 'tables' has already 
-        been checked.
-        
-    The function takes into account that some parts of the condition are
-    guaranteed to be true by employed 'ref' access methods (the code that
-    does this is located at the end, search down for "EQ_FUNC").

+  @brief
+
+  Check if
+   - @table uses "ref"-like access 
+   - it is based on "@field=certain_item" equality
+   - the equality will be true for any record returned by the access method
+  and return the certain_item if yes.
+  
+  @detail
+  
+  Equality won't necessarily hold if:
+   - the used index covers only part of the @field. 
+     Suppose, we have a CHAR(5) field and INDEX(field(3)). if you make a lookup
+     for 'abc', you will get both record with 'abc' and with 'abcde'.
+   - The type of access is actually ref_or_null, and so @field can be either 
+     a value or NULL.
+
+  @return 
+    Item that the field will be equal to

-  For the second algorithm the accumulation of records allows to optimize

-  The class JOIN_CACHE_BKA_UNIQUE supports the variant of the BKA join algorithm
-  that submits only distinct keys to the MRR interface. The records in the join
-  buffer of a cache of this class 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 occurance 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, then go key entries. 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. When a key is passed to the MRR interface it can be passed either with
-  an association link containing a reference to the header of the record chain
-  attached to the corresponding key entry in the hash table, or without any
-  association link. When the next record is returned by a call to the MRR 
-  function multi_range_read_next without any association (because if was not
-  passed  together with the key) then the key value is extracted from the
-  returned record and searched for it in the hash table. If there is any records
-  with such key the chain of them will be yielded as the result of this search.
-
-  The following picture represents a typical layout for the info stored in the
-  join buffer of a join cache object of the JOIN_CACHE_BKA_UNIQUE class.

-  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.

+  Skip trailing space.
+
+  On most systems reading memory in larger chunks (ideally equal to the size of
+  the chinks that the machine physically reads from memory) causes fewer memory
+  access loops and hence increased performance.
+  This is why the 'int' type is used : it's closest to that (according to how
+  it's defined in C).
+  So when we determine the amount of whitespace at the end of a string we do
+  the following :
+    1. We divide the string into 3 zones :
+      a) from the start of the string (__start) to the first multiple
+        of sizeof(int)  (__start_words)
+      b) from the end of the string (__end) to the last multiple of sizeof(int)
+        (__end_words)
+      c) a zone that is aligned to sizeof(int) and can be safely accessed
+        through an int *
+    2. We start comparing backwards from (c) char-by-char. If all we find is
+       space then we continue
+    3. If there are elements in zone (b) we compare them as unsigned ints to a
+       int mask (SPACE_INT) consisting of all spaces
+    4. Finally we compare the remaining part (a) of the string char by char.
+       This covers for the last non-space unsigned int from 3. (if any)
+
+   This algorithm works well for relatively larger strings, but it will slow
+   the things down for smaller strings (because of the additional calculations
+   and checks compared to the naive method). Thus the barrier of length 20
+   is added.
+
+   @param     ptr   pointer to the input string
+   @param     len   the length of the string
+   @return          the last non-space character

+\pard\sb100\sa100\b0\fs20 Version 2, June 1991 \par

+\pard Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.\fs24  \par

+\pard\s2\sb100\sa100\b Preamble\par

+\pard\sb100\sa100\b0\fs20 The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. \par

+When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. \par

+To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. \par

+For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. \par

+We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. \par

+Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. \par

+Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. \par

+The precise terms and conditions for copying, distribution and modification follow.\fs24  \par

+\pard\s2\sb100\sa100\b TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\par

+\pard\sb100\sa100\b0\fs20 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". \par

+Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. \par

+1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. \par

+You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. \par

+2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: \par

+\pard\fi-360\li720\sb100\sa100\tx720\f1\'b7\tab\f0 a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. \par

+\pard\fi-360\li720\sb100\sa100\f1\'b7\tab\f0 b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. \par

+\f1\'b7\tab\f0 c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) \par

+\pard These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. \par

+\pard\sb100\sa100 Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. \par

+In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. \par

+3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: \par

+\pard\fi-360\li720\sb100\sa100\tx720\f1\'b7\tab\f0 a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, \par

+\pard\fi-360\li720\sb100\sa100\f1\'b7\tab\f0 b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, \par

+\f1\'b7\tab\f0 c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) \par

+\pard The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. \par

+\pard\sb100\sa100 If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. \par

+4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. \par

+5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. \par

+6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. \par

+7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. \par

+If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. \par

+It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. \par

+This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. \par

+8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. \par

+9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. \par

+Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. \par

+10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. \par

+NO WARRANTY \par

+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. \par

+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. \par

+\pard\s2\sb100\sa100\b\fs24 END OF TERMS AND CONDITIONS \par

+How to Apply These Terms to Your New Programs\fs20\par

+\pard\sb100\sa100\b0 If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. \par

+To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. \par

+\pard one line to give the program's name and an idea of what it does. Copyright (C) yyyy name of author This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. \par

+\pard\sb100\sa100 Also add information on how to contact you by electronic and paper mail. \par

+If the program is interactive, make it output a short notice like this when it starts in an interactive mode: \par

+\pard Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. \par

+\pard\sb100\sa100 The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c' ; they could even be mouse-clicks or menu items--whatever suits your program. \par

+You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: \par

+\pard Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. signature of Ty Coon , 1 April 1989 Ty Coon, President of Vice \par

+\pard\sb100\sa100 This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.\par
