Analysis ======== Point in time recovery using mysqlbinlog containing queries operating on temporary tables results in an error. While writing the query log event in the binary log, the thread id used for execution of DROP TABLE and DELETE commands were incorrect. The thread variable 'thread_specific_used' is used to determine whether a specific thread id is to used while executing the statements i.e using 'SET @@session.pseudo_thread_id'. This variable was not set correctly for DROP TABLE query and was never set for DELETE query. The thread id is important for temporary tables since the tables are session specific. DROP TABLE and DELETE queries executed using a wrong thread id resulted in errors while applying the queries generated by mysqlbinlog utility. Fix === Set the 'thread_specific_used' THD variable for DROP TABLE and DELETE queries. ReviewBoard: 21833
