- # This test checks that in a dual-head setup
- # A->B->A, where A has --log-slave-updates (why would it?
- # assume that there is a C as slave of A),
- # then the Exec_master_log_pos of SHOW SLAVE STATUS does
- # not stay too low on B(BUG#13023 due to events ignored because
- # of their server id).
- # It also will test BUG#13861.
- source include/master-slave.inc;
- # set up "dual head"
- connection slave;
- reset master;
- connection master;
- --replace_result $SLAVE_MYPORT SLAVE_PORT
- eval change master to master_host="127.0.0.1",master_port=$SLAVE_MYPORT,master_user="root";
- start slave;
- # now we test it
- connection slave;
- create table t1 (n int);
- save_master_pos;
- connection master;
- sync_with_master;
- # Now test BUG#13861. This will be enabled when Guilhem fixes this
- # bug.
- # stop slave
- # create table t2 (n int); # create one ignored event
- # save_master_pos;
- # connection slave;
- # sync_with_master;
- # connection slave;
- # show tables;
- # save_master_pos;
- # create table t3 (n int);
- # connection master;
- # bug is that START SLAVE UNTIL may stop too late, we test that by
- # asking it to stop before creation of t3.
- # start slave until master_log_file="slave-bin.000001",master_log_pos=195;
- # wait until it's started (the position below is the start of "CREATE
- # TABLE t2") (otherwise wait_for_slave_to_stop may return at once)
- # select master_pos_wait("slave-bin.000001",137);
- # wait_for_slave_to_stop;
- # then BUG#13861 causes t3 to show up below (because stopped too
- # late).
- # show tables;
- # start slave;
- # BUG#13023 is that Exec_master_log_pos may stay too low "forever":
- connection master;
- create table t4 (n int); # create 3 ignored events
- create table t5 (n int);
- create table t6 (n int);
- save_master_pos;
- connection slave;
- sync_with_master;
- connection slave;
- save_master_pos;

- # then BUG#13023 caused hang below ("master" looks behind, while it's
- # not in terms of updates done).

- show tables;
