      Fix test failure on test MW-86 and remove MW-360 test. · 5017c261
      Jan Lindström authored
      Merged from mysql-wsrep-bugs following:
      
      GCF-1058 MTR test galera.MW-86 fails on repeated runs
      Wait for the sync point sync.wsrep_apply_cb to be reached before
      executing the test and clearing the debug flag sync.wsrep_apply_cb.
      
      The race scenario:
      
      Intended behavior:
      node2: set sync.wsrep_apply_cb in order to start waiting in the background INSERT
      node1: INSERT start
      node2 (background): INSERT start
      node1: INSERT end
      node2: send signal to background INSERT: "stop waiting and continue executing"
      node2: clear sync.wsrep_apply_cb as no longer needed
      node2 (background): consume the signal
      node2 (background): INSERT end
      node2: DROP TABLE
      node2: check no pending signals are left - ok
      
      What happens occasionally (unexpected):
      node2: set sync.wsrep_apply_cb in order to start waiting in the background INSERT
      node1: INSERT start
      node2 (background): INSERT start
      node1: INSERT end
      // The background INSERT still has _not_ reached the place where it starts
      // waiting for the signal:
      // DBUG_EXECUTE_IF("sync.wsrep_apply_cb", "now wait_for...");
      node2: send signal to background INSERT: "stop waiting and continue executing"
      node2: clear sync.wsrep_apply_cb as no longer needed
      // The background INSERT reaches DBUG_EXECUTE_IF("sync.wsrep_apply_cb", ...)
      // but sync.wsrep_apply_cb has already been cleared and the "wait" code is not
      // executed. The signal remains unconsumed.
      node2 (background): INSERT end
      node2: DROP TABLE
      node2: check no pending signals are left - failure, signal.wsrep_apply_cb is
      pending (not consumed)
      
      Remove MW-360 test case as it is not intended for MariaDB (uses
      MySQL GTID).
