Problem: When using the delayed slave feature, and the SQL thread is delaying, and the user issues STOP SLAVE, the event we wait for was executed. It should not be executed. Fix: Check the return value from the delay function, slave.cc:slave_sleep(). If the return value is 1, it means the thread has been stopped, in this case we don't execute the statement. Also, refactored the test case for delayed slave a little: added the test script include/rpl_assert.inc, which asserts that a condition holds and prints a message if not. Made rpl_delayed_slave.test use this. The advantage is that the test file is much easier to read and maintain, because it is clear what is an assertion and what is not, and also the expected result can be found in the test file, you don't have to compare it to the result file.

# ==== Purpose ====
|
|
#
|
|
# Auxiliary file used by rpl_delayed_slave.test. This assumes that an
|
|
# 'INSERT INTO t1...' query has been executed on the master. It does
|
|
# this:
|
|
#
|
|
# - After half the delay, check the status. It should be delaying and
|
|
# the query should not have executed.
|
|
#
|
|
# - After one and a half delay, check the status. It should not be
|
|
# delaying and the query should be executed.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# --let $query_number= 4
|
|
# --source extra/rpl_tests/delayed_slave_wait_on_query.inc
|
|
#
|
|
# Parameters:
|
|
# $query_number
|
|
# The value of the 'b' column in t1 for the row inserted by the query
|
|
# we are waiting for.
|
