# 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;

# 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":
