Hi Brandon, The test failure in https://jira.mariadb.org/browse/MDEV-28776 (the one with 10 failed retries after deadlock, not the freebsd failures) seems like it could be something serious. But it has been very difficult to track down. I believe you have tried different things, and I also tried hard to reproduce it, so far without success. But it's still failing occasionally in actual buildbot runs. What do you think about pushing the below to the different branches? It makes the test case log InnoDB information about deadlocks encountered. This way, when it fails the next time in buildbot we can see 1) what kind of InnoDB deadlock is triggering the problem, if any; and 2) if it actually gets a deadlock inside InnoDB 10 times in a row, or if it is something else. - Kristian. ----------------------------------------------------------------------- Author: Kristian Nielsen <knielsen@knielsen-hq.org> Date: Sun Jul 9 15:18:03 2023 +0200 MDEV-28776: rpl.rpl_mark_optimize_tbl_ddl fails with timeout on sync_with_master This commit just extends the testcase to include some more information when the test failure occurs. The failure has so far only been reproducible in buildbot runs.
