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.
1. Fixes within the testscripts (affects rpl_ddl.test and rpl_ndb_ddl.test)
- slave connection is only an observer (-> AUTOCOMMIT = 0)
This removes the problem with the hanging test around DROP DATABASE (NDB). The hanging test around DROP DATABASE is a difference to InnoDB/MyISAm behaviour but fare
away of a clear bug. IMHO this behaviour does not violate the SQL standard and should be therefore simply accepted.
- removal of wrong comments
- CREATE/DROP TEMPORARY TABLE must not cause implicit commit of the current transaction.
NDB behaves here correct and InnoDB/Falcon wrong.
- Add a missing connection slave
- Reenable the test rpl_ndb_ddl.
2. Disable rpl_ddl.test because of Bug#26418.
3. Reenable rpl_ndb_ddl.test
4. Improvements (affect rpl_ddl.test and rpl_ndb_ddl.test)
- Better + extended comments which should prevent that somebody accidently destroys the logics of the test
- Replace SELECT's printing comments by "--echo" (decreases the number of auxiliary SQL commands)
- Remove the need for include/rpl_stmt_seq2.inc (was mostly redundant to rpl_stmt_seq.inc)
- Remove extra/rpl_tests/rpl_ndb_ddl.test (corrected extra/rpl_tests/rpl_ddl.test is sufficient)
- Shift assignment of values to $show_binlog, $manipulate (variables useful for debugging) into the toplevel scripts
- The temporary tables get now their storage engine from the variable $temp_engine_type. (more deterministic testing conditions)
- Add additional protocol line if the connection is switched (was partially missing)
- Add two DML commands for comparison purposes
