      Description

      If SPIDER plugin is installed, XA COMMIT (or ROLLBACK) fails after XA recovery:

      The failure happens even if SPIDER itself is not involved in the transaction. It's enough just to have the plugin installed:

      --source include/have_innodb.inc
       
      install soname 'ha_spider.so';
       
      --connection default
      eval CREATE TABLE t1 (a INT) ENGINE=InnoDB;
       
      --connect (con1,localhost,root,,)
      XA START 'xa1';
      INSERT INTO t1 (a) VALUES (1),(2);
      XA END 'xa1';
      XA PREPARE 'xa1';
       
      --connection default
      --enable_reconnect
      --append_file $MYSQLTEST_VARDIR/tmp/mysqld.1.expect
      restart
      EOF
      --shutdown_server 0
      --source include/wait_until_disconnected.inc
      --source include/wait_until_connected_again.inc
      XA RECOVER;
      XA COMMIT 'xa1';
