# 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 Slave_open_temp_tables count.
|
|
# Fix: Decrement Slave_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 Slave_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

# with the help of information sent by Master through 'FormatDescription'

# proper cleanup. When Gtid mode is on and while slave SQL thread is
|
|
# generating DROP TEMPORARY statement for all these temporary tables,

# server is hitting an assert DEBUG_ASSERT(gtid.spec_type != UNDEF_GROUP)
