[GitHub] [couchdb] nickva opened a new pull request, #4623: Handle replicator instance start time during upgrades better
nickva opened a new pull request, #4623:
URL: https://github.com/apache/couchdb/pull/4623
During cluster upgrades from 3.2 to 3.3 when instance start time switched from being always `0` to an actual timestamp, replication jobs will crash when endpoints are upgraded. Replication jobs were started when endpoint emitted a `0` and then it becomes a non-`0` value which will crash the next checkpoint attempt.
After the crash jobs will restart and continue fine were they left off without rewinding. However they will make a logging mess while they crash. All four workers will exit the `{checkpoint_commit_failure,...}` error. This commit make it the checkpoint ignore mismatches if one of the instance start times is 0.

@big-r81 good idea, I thought it looked a bit smaller and better with shorter variables it's not a lot better. Reverted back to original names. Also added a comment indicated what is happening with the `<<"0">>` check there and why we're doing it.
