Current File : //usr/share/mysql-test/extra/rpl_tests/rpl_crash_safe.inc
# ==== Purpose ====
#
# This file is an engine to process commands like
# rpl_mixing_engines.inc. It has the same set of commands, and in
# addition the extra command 'recovery'. The 'configure' and 'clean'
# commands are also extended version of the same commands in
# rpl_mixing_engines.inc.
#
# ==== Usage ====
#
# --let $commands= command1 command2 ...
# --let $database_name= name
# --let $failure= d,debug_flag
# [--let $verbose= 1]
# --source include/rpl_mixing_engines.inc
#
# Parameters:
#
# $commands, $database_name, $verbose
# See rpl_mixing_engines.inc.
#
# $failure
# This debug symbol will be set. See the implementation for
# details.
#
# ==== Implementation ====
#
# This file has its own code for 'configure' and 'clean'. For other
# commands, this file first configures the server according to
# $failure, and then delegates the commands to rpl_mixing_engines.inc.
#
# Creates tables used throughout the test and changes the type of the
# mysql.slave_relay_log_info to Innodb.
#
