# ==== 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.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# [--let $use_gtids= 1]
|
|
# [--let $rpl_debug= 1]
|
|
# [--let $force_empty_channel_name= 1]
|
|
# --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_debug
|
|
# See include/rpl_init.inc
|
|
#
|
|
# $force_empty_channel_name
|
|
# Set it to 1 if you want to explicitly say that channel_name is
|
|
# empty channel name (equal to '') and not unspecified.
|
|
#
|
|
|
|
--let $include_filename= save_master_pos.inc
|
|
--source include/begin_include_file.inc
|
|
|
|
#
|
|
# Always save master positions, this will be useful to check missing GTIDs.
|
|
