# ==== Purpose ====
#
# Shut down replication initialized by include/rpl_init.inc.
#
# This syncs all servers, executes STOP SLAVE on all servers, executes
# CHANGE MASTER on all servers, and disconnects all connections
# configured by rpl_init.inc.
#
# It does not execute RESET MASTER or RESET SLAVE, because that would
# remove binlogs which are possibly useful debug information in case
# the test case later fails with a result mismatch. If you need that,
# source include/rpl_reset.inc before you source this file.
#
#
# ==== Usage ====
#
# [--let $rpl_only_running_threads= 1]
# [--let $rpl_debug= 1]
# [--let $rpl_group_replication= 1]
# [--let $rpl_gtid_utils= 1]
# [--let $rpl_assert_transaction_length= 1]
# --source include/rpl_end.inc
#
# Parameters:
# $rpl_skip_sync
# By default, all slaves are synced using rpl_sync.inc. Set this
# option to 1 to disable this behavior (note that you must
# manually sync all servers in this case). Normally you want to
# sync, but you need to disable sync if you use multi-source.
#
# $rpl_skip_delete_channels
# In multi-source repliation, to restore the SHOW SLAVE STATUS state,
# it is necessary to delete the channels that are created. By default,
# channels are deleted in multi-source. set it to 1, if channel deletion
# is not required.
#
# $rpl_only_running_threads
# If one or both of the IO and SQL threads is stopped, sync and
# stop only the threads that are running. See
# include/rpl_sync.inc and include/stop_slave.inc for details.
#
# $rpl_debug
# See include/rpl_init.inc
#
# $rpl_group_replication
# This checks for whether we have Group Replication enabled or not. Based
# on the check this parameter we execute change master or not in this
# inc file.
#
# $rpl_gtid_utils
# Source include/gtid_utils_end.inc on every server.
#
# $rpl_assert_transaction_length
# Source include/assert_transaction_length_all_logs.inc on every server.
#
# Note:
# This script will fail if Last_SQL_Error or Last_IO_Error is
# nonempty. If you expect an error in the SQL thread, you should
# normally call this script as follows:
#
# --source include/wait_for_slave_sql_error.inc
# --source include/stop_slave_io.inc
# RESET SLAVE;
# --let $rpl_only_running_threads= 1
# --source include/rpl_end.inc
#
#
# ==== Side effects ====
#
# Changes the current connection to 'default'.
