# Bug#76727: SLAVE ASSERTION IN UNPACK_ROW WITH ROLLBACK TO
# SAVEPOINT IN ERROR HANDLER
#
# Problem:
# ========
# "SAVEPOINT", "ROLLBACK TO savepoint" wipe out table map on slave during
# execution binary log events. For trigger the map is written to binary log once
# for all trigger body and if trigger contains "SAVEPOINT" or
# "ROLLBACK TO savepoint" statements any trigger's events after these
# statements will not have table map. This results in an assert on slave.
#
# Test:
# =====
# Test case 1:
# Create a trigger with exception handler which rollsback to a savepoint.
# Test proves that there will not be any assert during execution of rolling
# back to savepoint.
#
# Test case 2:
# Create a trigger which calls a procedure which in turn calls an exception
# handler which rollsback to a savepoint. Prove that it doesn't cause any
# assertion during execution.
#
# Test case 3:
# Create a simple trigger which creates a SAVEPOINT and ROLLSBACK to savepoint
# and doesn't follow with any other DML statement. Prove that it doesn't cause
# any assertion during execution.
#
# Test case 4:
# Create a trigger with SAVEPOINT and follows with a DML without ROLLBACK TO
# savepoint. Ensure that data is replicated properly.
#
# Test case 5:
# Create a trigger with SAVEPOINT and it does nothing. Do few DMLS following
# the trigger ensure that the data is replicated properly
#
# Test case 6:
# Create a stored function which creates a SAVEPOINT and ROLLSBACK to
# savepoint. Do few inserts following the stored function call and ensure that
# no assert is generated on slave and all the rows are replicated to slave.
#
# Test case 7:
# Create a stored function which creates a SAVEPOINT alone and follows with
# DMLS without ROLLBACK TO savepoint. Ensure that data is replicated properly.
#
# Test case 8:
# Create a stored function which has SAVEPOINT inside it and does noting. It
# should follow with other DMLs. Ensure that data is replicated properly.
