################################################################################ # BUG#20980932 MYSQLBINLOG GENERATES 'ROLLBACK' AFTER FD EVENT CAUSING 1782 # ERRRO # # mysqlbinlog prints "ROLLBACK" at the end of binlog file. The ROLLBACK # caused the error that "@@SESSION.GTID_NEXT cannot be set to ANONYMOUS # when @@GLOBAL.GTID_MODE = ON." # # It happened in below two cases: # - Case1. Binlog file doesn't include any data related events. # e.g. The binlog only includes: # Format_description_log_event # Rotate_log_event # # and mysqlbinlog output: # BINLOG '... the binary of Format_description_log_event ...' # ROLLBACK # # - Case2. Relay log file includes a Format_description_log_event of master # which is generated at starting server. # e.g. the relay log includes: # Format_description_log_event of relay log # Format_description_log_event of master(generated when starting server) # # and mysqlbinlog output: # BINLOG '... the binary of relay log's Format_description_log_event' # ROLLBACK # BINLOG '... the binary of master's Format_description_log_event' # # To fix it: # - ROLLBACK is not printed if there is no uncomplete transaction at the end # of a binlog. # - Format_description_log_event of relay log is not output as a 'BINLOG'. # - SET @@SESSION.GTID_NEXT = 'AUTOMATIC' is always printed out at the end of # a binlog. It is after the 'ROLLBACK' if the last transaction is # uncomplete. # # This test verify above two cases work well. ################################################################################ --source include/have_gtid.inc --source include/have_binlog_format_row.inc --echo # --echo # Verify Case2 works well --echo # --source include/master-slave.inc --let $master_file1 = query_get_value(SHOW MASTER STATUS, File, 1) --let $MASTER_DATADIR=`select @@datadir` --source include/rpl_connection_slave.inc --let $SLAVE_DATADIR=`select @@datadir` --let $relay_file1 = query_get_value(SHOW SLAVE STATUS, Relay_Log_File, 1) --exec $MYSQL_BINLOG --force-if-open $SLAVE_DATADIR/$relay_file1 | $MYSQL -uroot -S$MASTER_MYSOCK --exec $MYSQL_BINLOG --force-if-open $SLAVE_DATADIR/$relay_file1 | $MYSQL -uroot -S$SLAVE_MYSOCK --echo # --echo # Verify Case1 works well --echo # --source include/rpl_connection_master.inc FLUSH BINARY LOGS; --let $master_file2 = query_get_value(SHOW MASTER STATUS, File, 1) --exec $MYSQL_BINLOG --force-if-open $MASTER_DATADIR/$master_file1 $MASTER_DATADIR/$master_file2 | $MYSQL -uroot -S$SLAVE_MYSOCK --source include/rpl_end.inc
