+ failing statements Implicit DROP event for temporary table is not getting LOG_EVENT_THREAD_SPECIFIC_F flag, because, in the previous executed statement in the same thread, which might even be a failed statement, the thread_specific_used flag is set to FALSE (in mysql_reset_thd_for_next_command) and not set to TRUE before connection is shutdown. This means that implicit DROP event will take the FALSE value from thread_specific_used and will not set LOG_EVENT_THREAD_SPECIFIC_F in the event header. As a consequence, mysqlbinlog will not print the pseudo_thread_id from the DROP event, because one of the requirements for the printout is that this flag is set to TRUE. We fix this by setting thread_specific_used whenever we are binlogging a DROP in close_temporary_tables, and resetting it to its previous value afterward.

# ==== Purpose ====
|
|
#
|
|
# Test if statements used temporary tables are binlogged correctly
|
|
#
|
|
# ==== Method ====
|
|
#
|
|
# Use two connections, use temporary tables on both of them, and by
|
|
# switching connections between statements, the test can check if the
|
|
# statements are logged with the correct thread id.
|
|
#
|
|
# The statements current tested include:
|
|
# CREATE TEMPORARY TABLE
|
|
# CREATE TEMPORARY TABLE LIKE
|
|
# INSERT
|
|
# REPLACE
|
|
# UPDATE
|
|
# INSERT SELECT
|
|
# TRUNCATE
|
|
#
|
|
# Note: When adding new query statements, please add them between the
|
|
# two 'flush logs'. And aslo please make sure the connection is
|
|
# switched between each statement.
