# 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;
