# Bug#18364070 BACKPORT BUG#18236612 TO MYSQL-5.6
# Problem & Analysis : When Slave SQL thread detects that Master was restarted
# with the help of information sent by Master through 'FormatDescription'
# event, slave SQL drops all the opened temporary tables in order to have
# proper cleanup. While slave SQL thread is dropping the temporary tables, it
# is not decrementing Replica_open_temp_tables count.
# Fix: Decrement Replica_open_temp_tables count in this case.
# Steps to test:
# 1) Create a temporary table
# 2) Sync it with slave
# 3) Stop slave io thread
# 4) Kill Master which generates Format Description event
# 5) Restart Master again
# 6) Start slave io thread
# 7) Wait till SQL thread applies all events
# (which includes newly generated Format Description event)
# 8) Now verify that Replica_open_temp_tables has '0' value
# This same test steps with gtid enabled mode, works to test the following
# bug as well.
# Bug#18069107 SLAVE CRASHES WITH GTIDS,TEMP TABLE, STOP IO_THREAD, START SLAVE
# Problem & Analysis : When Slave SQL thread detects that Master was restarted

# generating DROP TEMPORARY statement for all these temporary tables,
