Problem: After START SLAVE, the Slave_IO_Status column of SHOW SLAVE STATUS goes from No to Yes asynchronously. That caused sporadic failures on pushbuild in rpl_stm_until since the test contains SHOW SLAVE STATUS right after START SLAVE. Fix: Wait until Slave_IO_Status becomes Yes after each START SLAVE. mysql-test/include/wait_for_slave_io_to_start.inc: Macro that waits until the Slave_IO_Running field of SHOW SLAVE STATUS becomes Yes. mysql-test/suite/rpl/r/rpl_stm_until.result: updated result file mysql-test/suite/rpl/t/rpl_stm_until.test: - Added wait_for_slave_io_to_start after each start slave. - Removed unused initialization of test variable $VERSION - Added comments.

# ==== Purpose ====
|
|
#
|
|
# Verify that START SLAVE UNTIL replicates until the given binlog
|
|
# position but not longer. Verify that START SLAVE UNTIL with various
|
|
# incorrect arguments gives an error.
|
|
#
|
|
# ==== Method ====
|
|
#
|
|
# On master, create a table and insert some rows. On slave, START
|
|
# SLAVE UNTIL so that it reads one event at a time, and check the
|
|
# table and the slave status each time.
|
|
#
|
|
# Then, on slave, run START SLAVE UNTIL with incorrect arguments and
|
|
# verify that it gives an error.
|
|
