# ==== Purpose ====
#
# Save the current position of the IO thread, just like
# save_master_pos.inc does for the master's position.
#
#
# ==== Usage ====
#
# [--let $use_gtids= 1]
# [--let $rpl_debug= 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_channel_name
# Uses this channel name rather than the default channel.
#
# $rpl_debug
# See include/rpl_init.inc
--let $include_filename= save_io_thread_pos.inc
--source include/begin_include_file.inc
if ($rpl_multi_source)
{
if ($rpl_channel_name == '')
{
--die ERROR IN TEST: when $rpl_multi_source is enabled, you must use $rpl_channel_name with save_io_thread_pos.inc
}
}
#
# Always save IO thread positions, this will be useful to check missing GTIDs.
