-=head1 NAME
-
-pt-log-player - Replay MySQL query logs.
-
-=head1 SYNOPSIS
-
-This tool is deprecated and will be removed in Percona Toolkit 2.2.
-
-Usage: pt-log-player [OPTION...] [DSN]
-
-pt-log-player splits and plays slow log files.
-
-Split slow.log on Thread_id into 16 session files, save in ./sessions:
-
-  pt-log-player --split Thread_id --session-files 16 --base-dir ./sessions slow.log
-
-Play all those sessions on host1, save results in ./results:
-
-  pt-log-player --play ./sessions --base-dir ./results h=host1
-
-Use L<pt-query-digest> to summarize the results:
-
-  pt-query-digest ./results/*
-
-=head1 RISKS
-
-The following section is included to inform users about the potential risks,
-whether known or unknown, of using this tool.  The two main categories of risks
-are those created by the nature of the tool (e.g. read-only tools vs. read-write
-tools) and those created by bugs.
-
-This tool is meant to load a server as much as possible, for stress-testing
-purposes.  It is not designed to be used on production servers.
-
-At the time of this release there is a bug which causes pt-log-player to
-exceed max open files during L<"--split">.
-
-The authoritative source for updated information is always the online issue
-tracking system.  Issues that affect this tool will be marked as such.  You can
-see a list of such issues at the following URL:
-L<http://www.percona.com/bugs/pt-log-player>.
-
-See also L<"BUGS"> for more information on filing bugs and getting help.
-
-=head1 DESCRIPTION
-
-pt-log-player does two things: it splits MySQL query logs into session files
-and it plays (executes) queries in session files on a MySQL server.  Only
-session files can be played; slow logs cannot be played directly without
-being split.
-
-A session is a group of queries from the slow log that all share a common
-attribute, usually Thread_id.  The common attribute is specified with
-L<"--split">.  Multiple sessions are saved into a single session file.
-See L<"--session-files">, L<"--max-sessions">, L<"--base-file-name"> and
-L<"--base-dir">.  These session files are played with L<"--play">.
-
-pt-log-player will L<"--play"> session files in parallel using N number of
-L<"--threads">.  (They're not technically threads, but we call them that
-anyway.)  Each thread will play all the sessions in its given session files.
-The sessions are played as fast as possible (there are no delays) because the
-goal is to stress-test and load-test the server.  So be careful using this
-script on a production server!
-
-Each L<"--play"> thread writes its results to a separate file.  These result
-files are in slow log format so they can be aggregated and summarized with
-L<pt-query-digest>.  See L<"OUTPUT">.
-
-=head1 OUTPUT
-
-Both L<"--split"> and L<"--play"> have two outputs: status messages printed to
-STDOUT to let you know what the script is doing, and session or result files
-written to separate files saved in L<"--base-dir">.  You can suppress all
-output to STDOUT for each with L<"--quiet">, or increase output with
-L<"--verbose">.
-
-The session files written by L<"--split"> are simple text files containing
-queries grouped into sessions.  For example:
-
-  -- START SESSION 10
-
-  use foo
-
-  SELECT col FROM foo_tbl
-
-The format of these session files is important: each query must be a single
-line separated by a single blank line.  And the "-- START SESSION" comment
-tells pt-log-player where individual sessions begin and end so that L<"--play">
-can correctly fake Thread_id in its result files.
-
-The result files written by L<"--play"> are in slow log format with a minimal
-header: the only attributes printed are Thread_id, Query_time and Schema.
-
-=head1 OPTIONS
-
-Specify at least one of L<"--play">, L<"--split"> or L<"--split-random">.
-
-L<"--play"> and L<"--split"> are mutually exclusive.
-
-This tool accepts additional command-line arguments.  Refer to the
-L<"SYNOPSIS"> and usage information for details.
-
-=over
-
-=item --ask-pass
-
-group: Play
-
-Prompt for a password when connecting to MySQL.
-
-=item --base-dir
-
-type: string; default: ./
-
-Base directory for L<"--split"> session files and L<"--play"> result file.
-
-=item --base-file-name
-
-type: string; default: session
-
-Base file name for L<"--split"> session files and L<"--play"> result file.
-
-Each L<"--split"> session file will be saved as <base-file-name>-N.txt, where
-N is a four digit, zero-padded session ID.  For example: session-0003.txt.
-
-Each L<"--play"> result file will be saved as <base-file-name>-results-PID.txt,
-where PID is the process ID of the executing thread.
-
-All files are saved in L<"--base-dir">.
-
-=item --charset
-
-short form: -A; type: string; group: Play
-
-Default character set.  If the value is utf8, sets Perl's binmode on STDOUT to
-utf8, passes the mysql_enable_utf8 option to DBD::mysql, and runs SET NAMES UTF8
-after connecting to MySQL.  Any other value sets binmode on STDOUT without the
-utf8 layer, and runs SET NAMES after connecting to MySQL.
-
-=item --config
-
-type: Array
-
-Read this comma-separated list of config files; if specified, this must be the
-first option on the command line.
-
-=item --defaults-file
-
-short form: -F; type: string
-
-Only read mysql options from the given file.
-
-=item --dry-run
-
-Print which processes play which session files then exit.
-
-=item --filter
-
-type: string; group: Split
-
-Discard L<"--split"> events for which this Perl code doesn't return true.
-
-This option only works with L<"--split">.
-
-This option allows you to inject Perl code into the tool to affect how the
-tool runs.  Usually your code should examine C<$event> to decided whether
-or not to allow the event.  C<$event> is a hashref of attributes and values of
-the event being filtered.  Or, your code could add new attribute-value pairs
-to C<$event> for use by other options that accept event attributes as their
-value.  You can find an explanation of the structure of C<$event> at
-L<http://code.google.com/p/maatkit/wiki/EventAttributes>.
-
-There are two ways to supply your code: on the command line or in a file.
-If you supply your code on the command line, it is injected into the following
-subroutine where C<$filter> is your code:
-
-   sub {
-      PTDEBUG && _d('callback: filter');
-      my( $event ) = shift;
-      ( $filter ) && return $event;
-   }
-
-Therefore you must ensure two things: first, that you correctly escape any
-special characters that need to be escaped on the command line for your
-shell, and two, that your code is syntactically valid when injected into
-the subroutine above.
-
-Here's an example filter supplied on the command line that discards
-events that are not SELECT statements:
-
-  --filter '$event->{arg} =~ m/^select/i'
-
-The second way to supply your code is in a file.  If your code is too complex
-to be expressed on the command line that results in valid syntax in the
-subroutine above, then you need to put the code in a file and give the file
-name as the value to L<"--filter">.  The file should not contain a shebang
-(C<#!/usr/bin/perl>) line.  The entire contents of the file is injected into
-the following subroutine:
-
-   sub {
-      PTDEBUG && _d('callback: filter');
-      my( $event ) = shift;
-      $filter && return $event;
-   }
-
-That subroutine is almost identical to the one above except your code is
-not wrapped in parentheses.  This allows you to write multi-line code like:
-
-   my $event_ok;
-   if (...) {
-      $event_ok = 1;
-   }
-   else {
-      $event_ok = 0;
-   }
-   $event_ok
-
-Notice that the last line is not syntactically valid by itself, but it
-becomes syntactically valid when injected into the subroutine because it
-becomes:
-
-   $event_ok && return $event;
-
-If your code doesn't compile, the tool will die with an error.  Even if your
-code compiles, it may crash to tool during runtime if, for example, it tries
-a pattern match an undefined value.  No safeguards of any kind are provided so
-code carefully!
-
-=item --help
-
-Show help and exit.
-
-=item --host
-
-short form: -h; type: string; group: Play
-
-Connect to host.
-
-=item --iterations
-
-type: int; default: 1; group: Play
-
-How many times each thread should play all its session files.
-
-=item --max-sessions
-
-type: int; default: 5000000; group: Split
-
-Maximum number of sessions to L<"--split">.
-
-By default, C<pt-log-player> tries to split every session from the log file.
-For huge logs, however, this can result in millions of sessions.  This
-option causes only the first N number of sessions to be saved.  All sessions
-after this number are ignored, but sessions split before this number will
-continue to have their queries split even if those queries appear near the end
-of the log and after this number has been reached.
-
-=item --only-select
-
-group: Play
-
-Play only SELECT and USE queries; ignore all others.
-
-=item --password
-
-short form: -p; type: string; group: Play
-
-Password to use when connecting.
-
-=item --pid
-
-type: string
-
-Create the given PID file.  The file contains the process ID of the script.
-The PID file is removed when the script exits.  Before starting, the script
-checks if the PID file already exists.  If it does not, then the script creates
-and writes its own PID to it.  If it does, then the script checks the following:
-if the file contains a PID and a process is running with that PID, then
-the script dies; or, if there is no process running with that PID, then the
-script overwrites the file with its own PID and starts; else, if the file
-contains no PID, then the script dies.
-
-=item --play
-
-type: string; group: Play
-
-Play (execute) session files created by L<"--split">.
-
-The argument to play must be a comma-separated list of session files
-created by L<"--split"> or a directory.  If the argument is a directory,
-ALL files in that directory will be played.
-
-=item --port
-
-short form: -P; type: int; group: Play
-
-Port number to use for connection.
-
-=item --print
-
-group: Play
-
-Print queries instead of playing them; requires L<"--play">.
-
-You must also specify L<"--play"> with L<"--print">.  Although the queries
-will not be executed, L<"--play"> is required to specify which session files to
-read.
-
-=item --quiet
-
-short form: -q
-
-Do not print anything; disables L<"--verbose">.
-
-=item --[no]results
-
-default: yes
-
-Print L<"--play"> results to files in L<"--base-dir">.
-
-=item --session-files
-
-type: int; default: 8; group: Split
-
-Number of session files to create with L<"--split">.
-
-The number of session files should either be equal to the number of
-L<"--threads"> you intend to L<"--play"> or be an even multiple of
-L<"--threads">.  This number is important for maximum performance because it:
-
-  * allows each thread to have roughly the same amount of sessions to play
-  * avoids having to open/close many session files
-  * avoids disk IO overhead by doing large sequential reads
-
-You may want to increase this number beyond L<"--threads"> if each session
-file becomes too large.  For example, splitting a 20G log into 8 sessions
-files may yield roughly eight 2G session files.
-
-See also L<"--max-sessions">.
-
-=item --set-vars
-
-type: string; group: Play; default: wait_timeout=10000
-
-Set these MySQL variables.  Immediately after connecting to MySQL, this string
-will be appended to SET and executed.
-
-=item --socket
-
-short form: -S; type: string; group: Play
-
-Socket file to use for connection.
-
-=item --split
-
-type: string; group: Split
-
-Split log by given attribute to create session files.
-
-Valid attributes are any which appear in the log: Thread_id, Schema,
-etc.
-
-=item --split-random
-
-group: Split
-
-Split log without an attribute, write queries round-robin to session files.
-
-This option, if specified, overrides L<"--split"> and causes the log to be
-split query-by-query, writing each query to the next session file in round-robin
-style.  If you don't care about "sessions" and just want to split a lot into
-N many session files and the relation or order of the queries does not matter,
-then use this option.
-
-=item --threads
-
-type: int; default: 2; group: Play
-
-Number of threads used to play sessions concurrently.
-
-Specifies the number of parallel processes to run.  The default is 2.  On
-GNU/Linux machines, the default is the number of times 'processor' appears in
-F</proc/cpuinfo>.  On Windows, the default is read from the environment.
-In any case, the default is at least 2, even when there's only a single
-processor.
-
-See also L<"--session-files">.
-
-=item --type
-
-type: string; group: Split
-
-The type of log to L<"--split"> (default slowlog).  The permitted types are
-
-=over
-
-=item binlog
-
-Split the output of running C<mysqlbinlog> against a binary log file.
-Currently, splitting binary logs does not always work well depending
-on what the binary logs contain.  Be sure to check the session files
-after splitting to ensure proper L<"OUTPUT">.
-
-If the binary log contains row-based replication data, you need to run
-C<mysqlbinlog> with options C<--base64-output=decode-rows --verbose>,
-else invalid statements will be written to the session files.
-
-=item genlog
-
-Split a general log file.
-
-=item slowlog
-
-Split a log file in any variation of MySQL slow-log format.
-
-=back
-
-=item --user
-
-short form: -u; type: string; group: Play
-
-User for login if not current user.
-
-=item --verbose
-
-short form: -v; cumulative: yes; default: 0
-
-Increase verbosity; can be specified multiple times.
-
-This option is disabled by L<"--quiet">.
-
-=item --version
-
-Show version and exit.
-
-=item --[no]warnings
-
-default: no; group: Play
-
-Print warnings about SQL errors such as invalid queries to STDERR.

-
-=head1 DSN OPTIONS
-
-These DSN options are used to create a DSN.  Each option is given like
-C<option=value>.  The options are case-sensitive, so P and p are not the
-same option.  There cannot be whitespace before or after the C<=> and
-if the value contains whitespace it must be quoted.  DSN options are
-comma-separated.  See the L<percona-toolkit> manpage for full details.

-=head1 ENVIRONMENT
-
-The environment variable C<PTDEBUG> enables verbose debugging output to STDERR.
-To enable debugging and capture all output to a file, run the tool like:
-
-   PTDEBUG=1 pt-log-player ... > FILE 2>&1
-
-Be careful: debugging output is voluminous and can generate several megabytes
-of output.
-
