Assertion during graceful shutdown with wsrep_on=OFF

    XMLWordPrintable

Details

    Description

      A graceful shutdown of a galera node may result in assertion:

      mariadbd: /home/sciascid/Workspace/src/mariadb-server/sql/service_wsrep.cc:264: my_bool wsrep_thd_is_aborting(const THD*): Assertion `((&(&thd->LOCK_thd_data)->m_mutex)->count > 0 && pthread_equal(pthread_self(), (&(&thd->LOCK_thd_data)->m_mutex)->thread))' failed.

      This issue was originally found in 10.5, on MTR test galera_3nodes.inconsistency_shutdown. A simpler test was devised that reproduces on 10.4 as well:

      --source include/galera_cluster.inc
      		 
      --connect node_2a, 127.0.0.1, root, , test, $NODE_MYPORT_2
      		 
      --connection node_2a
      		 
      CREATE TABLE t1 (f1 INTEGER PRIMARY KEY);
      		 
      --connection node_2
      		 
      SET GLOBAL wsrep_on=OFF;
      		 
      --source include/shutdown_mysqld.inc
