# Some errors that cause the slave SQL thread to stop are not shown in
|
|
# the Slave_SQL_Error column of "SHOW SLAVE STATUS". Instead, the error
|
|
# is only in the server's error log.
|
|
#
|
|
# Two failures and their respective reporting are verified:
|
|
#
|
|
# 1 - Failures during slave thread initialization
|
|
# 2 - Failures while processing queries passed through the init_slave
|
|
# option.
|
|
#
|
|
# In order to check the first type of failure, we inject a fault in the
|
|
# SQL/IO Threads through SET GLOBAL debug.
|
|
#
|
|
# To check the second type, we set @@global.init_slave to an invalid
|
|
# command thus preventing the initialization of the SQL Thread.
|
|
#
|
|
# Obs:
|
|
# 1 - Note that testing failures while initializing the relay log position
|
|
# is hard as the same function is called before the code reaches the point
|
|
# that we want to test.
|
|
#
|
|
# 2 - This test does not target failures that are reported while applying
|
|
# events such as duplicate keys, errors while reading the relay-log.bin*,
|
|
# etc. Such errors are already checked on other tests.
