Kristian Nielsen	04e114aec0	Fix sporadic failure of rpl.parallel_backup_xa_debug ... The test case set debug_sync=RESET without waiting for the server thread to receive the prior signal. This can cause the signal to be lost, the thread to not wake up, and thus the test to time out. Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org>	2025-03-13 18:58:12 +01:00
Monty	066f920484	MDEV-35110 Deadlock on Replica during BACKUP STAGE BLOCK_COMMIT on XA transactions ... This is an extension of MDEV-30423 "Deadlock on Replica during BACKUP STAGE BLOCK_COMMIT on XA transactions" The original commit in MDEV-30423 was not complete as some usage in XA of MDL_BACKUP_COMMIT locks did not set thd->backup_commit_lock. This is required to be set when using parallel replication. Fixed by ensuring that all usage of BACKUP_COMMIT lock i XA is uniform and all sets thd->backup_commit_lock. I also changed all locks to be MDL_EXPLICIT to keep also that part uniform. A regression test is added.	2024-10-28 13:29:21 +02:00
