      Fix some failing tests on Windows · d2617343
      Vladislav Vaintroub authored
      - ensure that mtr supressions table is flushed before doing controlled crash and restart
      - use DBUG_SUICIDE() rather than abort() in partition tests - avoids a crash message/warning
      - disable  perfschema all_instances test on Windows- there are  legitimate reasons  for output to be different on  Unix (some different threads, some different locks), the differences are expected to grow in the future, e.g with threadpool.

      Bug #11766513 - 59641: Prepared XA transaction in system after hard crash · 0ff2a182
      Marko Mäkelä authored
      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.
