queries if query was killed Since we rely on thd->is_error() to decide whether we should COMMIT or ROLLBACK after a query execution, check the query 'killed' state and throw an error before calling ha_autocommit_or_rollback(), not after. The patch was tested manually. For reliable results, the test case would have to KILL QUERY while a DELETE/UPDATE query in another thread is still running. I don't see a way to achieve this kind of synchronization in our test suite (no debug_sync in 5.1).
