[GitHub] [activemq-artemis] franz1981 opened a new pull request #3687: ARTEMIS-3340 Atomic server restart and clean dirty activation: fix testFailbackTimeout
franz1981 opened a new pull request #3687:
URL: https://github.com/apache/activemq-artemis/pull/3687
It's going to fix intermittent failures of `testFailbackTimeout`:
- Server restart is now atomic with other server operations (start/stop): it won't make a racy stop to be lost. This is mostly affecting tests that try stop a server while being restarted
- Existing replication mechanism is very asynchronous by design and a live stop while backup data is not fully in sync can cause the backup to restart believing to have "good" in-sync data (because the activation sequence and NodeID are fine); this can affect both test that interrupt a syncing process mid-air AND real world.
The latter requires more attention in a separate JIRA, because if backup crash after written the right NodeID and activation sequence (and live was stopped/crashed, before incrementing the coordinated sequence) it can still be restarted and, if the data is good, believe to be a candidate to be live (maybe is correct, but need some deeper investigation!).
The current fix just reset the local activation sequence to let this broker restart without activating by accident.
