- # Clean up old slave's binlogs.
- # The slave is started with --log-slave-updates
- # and this test does SHOW BINLOG EVENTS on the slave's
- # binlog. But previous tests can influence the current test's
- # binlog (e.g. a temporary table in the previous test has not
- # been explicitly deleted, and at the beginning of the current
- # test the slave immediately writes DROP TEMPORARY TABLE this_old_table).
- # We wait for the slave to have written all he wants to the binlog
- # (otherwise RESET MASTER may come too early).

- # We are going to read the slave's binlog which contains file_id (for some LOAD
- # DATA INFILE); to make it repeatable (not influenced by other tests), we need
- # to stop and start the slave, to be sure file_id will start from 1.
- # This can be done with 'server_stop slave', but
- # this would require the manager, so most of the time the test will be skipped
- # :(
- # To workaround this, I (Guilhem) add a (empty) rpl_log-slave.opt (because when
- # mysql-test-run finds such a file it restarts the slave before doing the
- # test). That's not very elegant but I could find no better way, sorry.

- # We need an extra update before doing save_master_pos.
- # Otherwise, an unlikely scenario may occur:
- # * When the master's binlog_dump thread reads the end of master-bin.001,
- # it send the rotate event which is at this end, plus a fake rotate event
- # because it's starting to read a new binlog.
- # save_master_pos will record the position of the first of the two rotate
- # (because the fake one is not in the master's binlog anyway).
- # * Later the slave waits for the position of the first rotate event,
- # and it may quickly stop (in 'slave stop') without having received the fake
- # one.
- # So, depending on a few milliseconds, we end up with 2 rotate events in the
- # relay log or one, which influences the output of SHOW SLAVE STATUS, making
- # it not predictable and causing random test failures.
- # To make it predictable, we do a useless update now, but which has the
- # interest of making the slave catch both rotate events.
