log-slave-updates and circul repl This is a test case fix for BUG#13861. mysql-test/r/rpl_dual_pos_advance.result: Fix for a test case for BUG#13861. mysql-test/t/rpl_dual_pos_advance.test: Fix for a test case for BUG#13861. master_pos_wait() requires slave sql thread running. But it is not guaranteed for this test case. As we use start slave until it may execute all events and shutdown before master_pos_wait() is started. On the other hand it is safe just to wait for slave to stop here, as start slave returns _after_ sql thread is started.

# 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.
