Bug#20627 - INSERT DELAYED does not honour auto_increment_* variables INSERT DELAYED ignored an explicitly set INSERT_ID and session specific auto_increment_* variables. The problem was that the inserts are done by a system thread, which does not have access to the session variables of the user thread. On a proposal of Guilhem I fixed it so that the variables are copied to the data structure for every delayed row. The system thread sets its session variables from these values. mysql-test/r/delayed.result: Bug#20830 - INSERT DELAYED does not honour SET INSERT_ID Bug#20627 - INSERT DELAYED does not honour auto_increment_* variables Turned some sleeps into FLUSH TABLEs. Added test cases. mysql-test/t/delayed.test: Bug#20830 - INSERT DELAYED does not honour SET INSERT_ID Bug#20627 - INSERT DELAYED does not honour auto_increment_* variables Turned some sleeps into FLUSH TABLEs. Added test cases. sql/sql_insert.cc: Bug#20830 - INSERT DELAYED does not honour SET INSERT_ID Bug#20627 - INSERT DELAYED does not honour auto_increment_* variables Added auto_increment/insert_id related variables to 'delayed_row'. The session values are copied to 'delayed_row' by the user thread. The delayed insert thread copies them to his session variables.
