# Test case1 verifies if the transaction statements will not be

# be rolled back on master after the master restarts when setting

# DEBUG POINT before binlog to make the master crash.

# Test case2 verifies if the transaction statements will be
|
|
# binlogged and replication will work fine, and the data will

# be recovered after the master restarts when setting DEBUG
|

# POINT after binlog, and before the date is committed to make
|
|
# the master crash.
