Edit File: stop_slave.inc

# ==== 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 $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
