- # test case to make slave thread get ahead by 22 bytes
- source include/master-slave.inc;
- # first, cause a duplicate key problem on the slave
- create table t1(n int auto_increment primary key);
- sync_slave_with_master;
- insert into t1 values (2);
- connection master;
- insert into t1 values(NULL);
- insert into t1 values(NULL);
- save_master_pos;
- connection slave;
- sleep 3; # there is no way around this sleep - we have to wait until
- # the slave tries to run the query, fails and aborts slave thread
- delete from t1 where n = 2;
- start slave;
- sync_with_master;
- #now the buggy slave would be confused on the offset but it can replicate
- #in order to make it break, we need to stop/start the slave one more time
- stop slave;
- connection master;
- # to be able to really confuse the slave, we need some non-auto-increment
- # events in the log
- create table t2(n int);
- drop table t2;
- insert into t1 values(NULL);
- save_master_pos;
- connection slave;
- start slave;
- #now the truth comes out - if the slave is buggy, it will never sync because
- #the slave thread is not able to read events
- sync_with_master;
- select * from t1;
- #clean up
- connection master;
- drop table t1;
- sync_slave_with_master;
- # End of 4.1 tests
