Current File : //usr/share/mysql-test/extra/rpl_tests/rpl_mts_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 ====
#
# See rpl_mixing_engines.inc.
#
# ==== Implementation ====
#
# This file has its own code for 'configure' and 'clean'. Other
# commands are delegated to rpl_mixing_engines.inc.
--let $rmcs_initial_commands= $commands
#
# Creates tables used throughout the test and changes the type of the
# mysql.slave_relay_log_info to Innodb.
#
