############################################################################### # Bug#18542111:ADD A TEST CASE TO TEST THE BINLOG TRANSACTION CACHE SIZE TO # 32768 # # Problem: # ======== # When the binlog's IO_CACHE grows up to exact 32768 bytes it # causes binlog events to get corrupt, if this transaction # precedes with a transaction whose IO_CACHE size is >32768. # # Test: # ===== # Create a transaction whose size is 37000 so that the event's size exceeds # 32768 and its contents are flushed to a file. Following this transaction # add a second transaction whose cache size is exactly 32768. # # During execution of third replace statement no assert should be caused. # Slave should be in sync with master. ############################################################################### --source include/have_binlog_format_row.inc --source include/have_innodb.inc --source include/master-slave.inc --connection master DROP TABLE IF EXISTS t1; CREATE TABLE t1(a varchar(40000))ENGINE=INNODB; INSERT INTO t1 VALUES (REPEAT('a',37000)); INSERT INTO t1 VALUES (REPEAT('b',32552)); --sync_slave_with_master --connection master --let $diff_tables=master:t1,slave:t1 --source include/diff_tables.inc DROP TABLE t1; --source include/rpl_end.inc
