|
# This test verifies the options --sync-relay-log-info and --relay-log-recovery by
|
|
# crashing the slave in two different situations:
|
|
# (case-1) - Corrupt the relay log with changes which were not processed by
|
|
# the SQL Thread and crashes it.
|
|
# (case-2) - Corrupt the master.info with wrong coordinates and crashes it.
|
|
#
|
|
# Case 1:
|
|
# 1 - Stops the SQL Thread
|
|
# 2 - Inserts new records into the master.
|
|
# 3 - Corrupts the relay-log.bin* which most likely has such changes.
|
|
# 4 - Crashes the slave
|
|
# 5 - Verifies if the slave is sync with the master which means that the information
|
|
# loss was circumvented by the recovery process.
|
|
#
|
|
# Case 2:
|
|
# 1 - Stops the SQL/IO Threads
|
|
# 2 - Inserts new records into the master.
|
|
# 3 - Corrupts the master.info with wrong coordinates.
|
|
# 4 - Crashes the slave
|
|
# 5 - Verifies if the slave is sync with the master which means that the information
|
|
# loss was circumvented by the recovery process.
