  Bug#20901025: SLAVE ASSERTION IN UNPACK_ROW WITH ROLLBACK TO
  SAVEPOINT IN ERROR HANDLER
parent 33ab30df
# ==== Purpose ====
#
# Waits until the slave SQL thread has been synced, i.e., all events
# have been copied over to slave. This is like mtr's built-in command
# sync_slave_with_master, but more flexible (e.g., you can set a
# custom timeout and you can force it to use GTIDs instead of filename
# and offset).
#
#
# ==== Usage ====
#
# [--let $sync_slave_connection= <connection_name>]
# [--let $use_gtids= 1]
# [--let $slave_timeout= NUMBER]
# [--let $rpl_debug= 1]
# --source include/sync_slave_io_with_master.inc
#
# Must be called on the master. Will change connection to the slave.
#
# Parameters:
#
# $use_gtids
# If set, uses GTIDs instead of filename and offset for positions.
#
# $sync_slave_connection
# By default, this script switches connection to 'slave'. If
# $sync_slave_connection is set, then '$sync_slave_connection' is
# used instead of 'slave'.
#
# $slave_timeout
# See include/wait_for_slave_param.inc.
#
# $rpl_debug
# See include/rpl_init.inc
--let $include_filename= sync_slave_sql_with_master.inc
--source include/begin_include_file.inc
save_master_pos;
--let $rpl_connection_name= slave
if ($sync_slave_connection)

# 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 rolls back 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 rolls back to a savepoint. Prove that it doesn't cause any
# assertion during execution.
#
# Test case 3:
# Create a simple trigger which does SAVEPOINT and ROLLBACK 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 does SAVEPOINT and ROLLBACK 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.
