MDEV-19746: Galera test failures because of wsrep_slave_threads identification Problem was that tests select INFORMATION_SCHEMA.PROCESSLIST processes from user system user and empty state. Thus, there is not clear state for slave threads. Changes: - Added new status variables that store current amount of applier threads (wsrep_applier_thread_count) and rollbacker threads (wsrep_rollbacker_thread_count). This will make clear how many slave threads of certain type there is. - Added THD state "wsrep applier idle" when applier slave thread is waiting for work. This makes finding slave/applier threads easier. - Added force-restart option for mtr to always restart servers between tests to avoid race on start of the test - Added wait_condition_with_debug to wait until the passed statement returns true, or the operation times out. If operation times out, the additional error statement will be executed Changes to be committed: new file: mysql-test/include/force_restart.inc new file: mysql-test/include/wait_condition_with_debug.inc modified: mysql-test/mysql-test-run.pl modified: mysql-test/suite/galera/disabled.def modified: mysql-test/suite/galera/r/MW-336.result modified: mysql-test/suite/galera/r/galera_kill_applier.result modified: mysql-test/suite/galera/r/galera_var_slave_threads.result new file: mysql-test/suite/galera/t/MW-336.cnf modified: mysql-test/suite/galera/t/MW-336.test modified: mysql-test/suite/galera/t/galera_kill_applier.test modified: mysql-test/suite/galera/t/galera_parallel_autoinc_largetrx.test modified: mysql-test/suite/galera/t/galera_parallel_autoinc_manytrx.test modified: mysql-test/suite/galera/t/galera_var_slave_threads.test modified: mysql-test/suite/wsrep/disabled.def modified: mysql-test/suite/wsrep/r/variables.result modified: mysql-test/suite/wsrep/t/variables.test modified: sql/mysqld.cc modified: sql/wsrep_mysqld.cc modified: sql/wsrep_mysqld.h modified: sql/wsrep_thd.cc modified: sql/wsrep_var.cc 2019-07-11 06:13:58 +02:00			`# ==== Purpose ====`
