# ==== Purpose ====
|
|
#
|
|
# 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 $rpl_channel_name= 'NAME']
|
|
# [--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.
|
|
#
|
|
# $rpl_channel_name
|
|
# If set, a FOR CHANNEL $rpl_channel_name is added.
|
|
#
|
|
# $slave_timeout
|
|
# See include/wait_for_slave_param.inc
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
