#
# Issues STOP SLAVE on the current connection. Then waits until both
# the IO and SQL threads have stopped, or until a timeout is reached.
#
# Please use this instead of 'STOP SLAVE', to reduce the risk of races
# in test cases.
#
# This will fail if the slave IO or SQL thread has an error. If you
# expect an error in the IO thread, use
# include/wait_for_slave_io_error.inc and include/stop_slave_sql.inc.
#
#
# ==== Usage ====
#
# [--let $rpl_only_running_threads= 1]
# [--let $slave_timeout= NUMBER]
# [--let $rpl_debug= 1]
# --source include/stop_slave.inc
#
# Parameters:
# $rpl_only_running_threads
# By default, this script executes STOP SLAVE unconditionally.
# This generates a warnings if one or both slave threads are
# already stopped. If $rpl_only_running_threads is set, this
# script checks which slave threads are running, and issues either
# STOP SLAVE, STOP SLAVE SQL_THREAD, STOP SLAVE IO_THREAD, or
# nothing.
#
# $slave_timeout
# See include/wait_for_slave_param.inc
#
# $rpl_debug
# See include/rpl_init.inc
--let $include_filename= stop_slave.inc
