# ==== Purpose ====
|
|
#
|
|
# Save the current binlog position on the master, just like the
|
|
# built-in mysqltest command save_master_pos. The advantage of this
|
|
# script is that the saved position is available to the test script.
|
|
#
|
|
# The script will generate a channel name automatically if the
|
|
# $rpl_multi_source is set but no $rpl_channel_name is specified. The
|
|
# automatically generated channel name is based on the server_id of
|
|
# the master to sync with.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# [--let $use_gtids= 1]
|
|
# [--let $rpl_debug= 1]
|
|
# [--let $rpl_channel_name= 'NAME']
|
|
# --source include/save_master_pos.inc
|
|
#
|
|
# Typically, you would use this script together with
|
|
# include/sync_io_with_master.inc
|
|
#
|
|
# Parameters:
|
|
#
|
|
# $use_gtids
|
|
# By default, this script saves the binlog file and offset. If
|
|
# $use_gtids is set, this script saves the gtids.
|
|
#
|
|
# $rpl_channel_name
|
|
# Uses this channel name rather than the default channel.
|
|
# When $rpl_multi_source is set and $rpl_channel_name is not set this
|
|
# include will guess the channel name based on master's server_id.
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
|

# Always save master positions, this will be useful to check missing GTIDs.
