######################################################################
# 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.
