# Requires statement logging -- source include/master-slave.inc # 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). save_master_pos; connection slave; sync_with_master; stop slave; reset master; reset slave; # 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).
