Bug #11766513 - 59641: Prepared XA transaction in system after hard crash causes future shutdown hang InnoDB would hang on shutdown if any XA transactions exist in the system in the PREPARED state. This has been masked by the fact that MySQL would roll back any PREPARED transaction on shutdown, in the spirit of Bug #12161 Xa recovery and client disconnection. [mysql-test-run] do_shutdown_server: Interpret --shutdown_server 0 as a request to kill the server immediately without initiating a shutdown procedure. xid_cache_insert(): Initialize XID_STATE::rm_error in order to avoid a bogus error message on XA ROLLBACK of a recovered PREPARED transaction. innobase_commit_by_xid(), innobase_rollback_by_xid(): Free the InnoDB transaction object after rolling back a PREPARED transaction. trx_get_trx_by_xid(): Only consider transactions whose trx->is_prepared flag is set. The MySQL layer seems to prevent attempts to roll back connected transactions that are in the PREPARED state from another connection, but it is better to play it safe. The is_prepared flag was introduced in the InnoDB Plugin. trx_n_prepared: A new counter, counting the number of InnoDB transactions in the PREPARED state. logs_empty_and_mark_files_at_shutdown(): On shutdown, allow trx_n_prepared transactions to exist in the system. trx_undo_free_prepared(), trx_free_prepared(): New functions, to free the memory objects of PREPARED transactions on shutdown. This is not needed in the built-in InnoDB, because it would collect all allocated memory on shutdown. The InnoDB Plugin needs this because of innodb_use_sys_malloc. trx_sys_close(): Invoke trx_free_prepared() on all remaining transactions.
