Marko Mäkelä fb5d579462 MDEV-13987 Hang in FLUSH TABLES...FOR EXPORT ... trx_purge_stop(): Release purge_sys->latch before attempting to wake up the purge threads, so that they can actually wake up. This is a regression of commit a13a636c74 which attempted to fix MDEV-11802 by ensuring that srv_purge_wakeup() will actually wait until all purge threads wake up. Due to the purge_sys->latch, the threads might never wake up, because some purge threads could end up waiting for purge_sys->latch in trx_undo_prev_version_build() while holding dict_operation_lock in shared mode. This in turn would block any DDL operations, the InnoDB master thread, and InnoDB shutdown.		2018-05-14 18:19:20 +03:00
