Bug #38694 Race condition in replication thread shutdown The issue of the current bug is unguarded access to mi->slave_running by the shutdown thread calling end_slave() that is bug#29968 (alas happened not to be cross-linked with the current bug) Fixed: with removing the unguarded read of the running status and perform reading it in terminate_slave_thread() at time run_lock is taken (mostly bug#29968 backporting, still with some improvements over that patch - see the error reporting from terminate_slave_thread()). Issue of bug#38716 is fixed here for 5.0 branch as well. Note: There has been a separate artifact identified - a race condition between init_slave() and end_slave() - reported as Bug#44467. 2009-04-28 14:46:07 +03:00			`# Testing replication threads stopping concurrency issue`
