Jukka Zitting updated JCR-2786:
-------------------------------
Fix Version/s: 2.2.0
> Cluster sync not always done when calling session.refresh(..)
> -------------------------------------------------------------
>
> Key: JCR-2786
> URL: https://issues.apache.org/jira/browse/JCR-2786
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: clustering
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Fix For: 2.2.0
>
>
> Session.refresh(..) is supposed to synchronize cluster changes, but this
> doesn't always happen, specially if the syncDelay is low. The reason is a
> wrong assumption in ClusterNode.sync: The code there to avoid duplicate sync
> calls doesn't always work as expected. The following algorithm is used:
> int count = syncCount;
> syncLock.acquire();
> if (count == syncCount) {
> journalSync();
> syncCount++;
> }
> syncLock.release();
> The problem is that the background thread might be at the line "syncCount++"
> when Session.refresh(..) is called, so that the main thread believes
> journalSync was already called and thus doesn't call it.
