The test case was failing because it contained instructions
to close/reopen files, when they were in use. This raises
problems in windows. Example of such instruction:
---exec echo "failure" > $MYSQLD_SLAVE_DATADIR/$file
The test also contains commands that are not platform
agnostic. Example:
--exec cat $MYSQLD_SLAVE_DATADIR/master.backup > \
$MYSQLD_SLAVE_DATADIR/master.info
We fix this by just truncating the necessary file and write
"failure" into it (ie, without closing the file). The
platform specific instruction is removed from the test
case as it seems redundant.

# 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.
