# Test case1 verifies if the transaction statements will not be
# binlogged and replication will work fine, but the data will
# 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.
#
# Test case3 verifies if the halfly binlogged transaction 
# statements will be trimmed from the crashed binlog file
# and the data will not be recovered successfully after
# the master restarts when setting DEBUG POINT in the
# middle of binlog to make the master crash
#
# Test case4 verifies if the halfly binlogged non-transaction
# statement will be trimmed from the crashed binlog file
# and the data will not be recovered successfully after
# the master restarts when setting DEBUG POINT in the
# middle of binlog to make the master crash.
