Some of the test cases reference to binlog position and these position numbers are written into result explicitly. It is difficult to maintain if log event format changes. There are a couple of cases explicit position number appears, we handle them in different ways A. 'CHANGE MASTER ...' with MASTER_LOG_POS or/and RELAY_LOG_POS options Use --replace_result to mask them. B. 'SHOW BINLOG EVENT ...' Replaced by show_binlog_events.inc or wait_for_binlog_event.inc. show_binlog_events.inc file's function is enhanced by given $binlog_file and $binlog_limit. C. 'SHOW SLAVE STATUS', 'show_slave_status.inc' and 'show_slave_status2.inc' For the test cases just care a few items in the result of 'SHOW SLAVE STATUS', only the items related to each test case are showed. 'show_slave_status.inc' is rebuild, only the given items in $status_items will be showed. 'check_slave_is_running.inc' and 'check_slave_no_error.inc' and 'check_slave_param.inc' are auxiliary files helping to show running status and error information easily.
