Infer target skip reason from older binlogs #6577
Conversation
Remove an assert that is too aggressive. When reading old binlogs the TargetSkipReason is not known, so TargetSkipReason.None is a valid state. We can do a best effort and infer the skip reason for format version 13. Fixes #6563

This is saying that if the condition was not null, the condition was false, which doesn't sound right.

Yes, if the target was skipped because of the false condition, we store the condition which was false. If it was skipped for other reasons, the condition will be null.

And if the condition was true, but we skipped it for another reason, condition would still be null instead of true? That's confusing, but ok.

Yes, we only store the Condition if the target was skipped because of false condition ;)

I've filed #6587 to track the work of adding tests for playing back binlogs of each version. I've had the same thoughts. |
