Currently, rpl_semi_sync is failing in PB due to the warning message: "Slave SQL: slave SQL thread is being stopped in the middle of " "applying of a group having updated a non-transaction table; " "waiting for the group completion ..." The problem started happening after the fix for BUG#11762407 what was automatically suppressing some warning messages. To fix the current issue, we suppress the aforementioned warning message and exploit the opportunity to make the sentence clearer.

# BUG#23300: Slow query log on slave does not log slow replicated statements
|
|
#
|
|
# Description:
|
|
# The slave should log slow queries replicated from master when
|
|
# --log-slow-slave-statements is used.
|
|
#
|
|
# Test is implemented as follows:
|
|
# i) stop slave
|
|
# ii) On slave, set long_query_time to a small value.
|
|
# ii) start slave so that long_query_time variable is picked by sql thread
|
|
# iii) On master, do one short time query and one long time query, on slave
|
|
# and check that slow query is logged to slow query log but fast query
|
|
# is not.
|
|
# iv) On slave, check that slow queries go into the slow log and fast dont,
|
|
# when issued through a regular client connection
|
|
# v) On slave, check that slow queries go into the slow log and fast dont
|
|
# when we use SET TIMESTAMP= 1 on a regular client connection.
|
|
# vi) check that when setting slow_query_log= OFF in a connection 'extra2'
|
|
# prevents logging slow queries in a connection 'extra'
|
|
#
|
|
# OBS:
|
|
# This test only runs for statement binlogging format because on row format
|
|
# slow queries do not get slow query logged.
|
|
# Note that due to the sleep() command the insert is written to the binary
|
|
# log in row format.
|
|

# Prepare slave for different long_query_time we need to stop the slave
|
|
# and restart it as long_query_time variable is dynamic and, after
|
|
# setting it, it only takes effect on new connections.
