Remove the exception that InnoDB does not report auto-increment locks waits to the parallel replication. There was an assumption that these waits could not cause conflicts with in-order parallel replication and thus need not be reported. However, this assumption is wrong and it is possible to get conflicts that lead to hangs for the duration of --innodb-lock-wait-timeout. This can be seen with three transactions: 1. T1 is waiting for T3 on an autoinc lock 2. T2 is waiting for T1 to commit 3. T3 is waiting on a normal row lock held by T2 Here, T3 needs to be deadlock killed on the wait by T1. Note: This should be null-merged to 10.6, as a different fix is needed there due to InnoDB lock code changes. Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org> |
