Problem: the test waits for a 'DROP TEMPORARY TABLE' event to appear in the master's binlog, then checks on the slave whether the number of temporary tables has decreased. The slave does not sync, causing a race. Fix: check for the 'DROP TEMPORARY TABLE' event on slave instead of on master. mysql-test/suite/rpl/t/rpl_trunc_temp.test: - Fixed BUG#37493 by waiting for the event on the slave instead of on the master. - Added comments.

# ==== Purpose ====
|
|
#
|
|
# Verify that Slave_open_temp_tables is increased when a temporary
|
|
# table is opened on the slave, and decreased when a temporary table
|
|
# is closed on the slave, and that it is preserved during 'DELETE FROM
|
|
# table' and 'TRUNCATE table'.
|
|
#
|
|
# ==== Method ====
|
|
#
|
|
# Create a temporary table on master, insert rows, and try:
|
|
# - delete rows from the table
|
|
# - truncate the table
|
|
# - drop the table
|
|
