Bulk close for 1.0.9
> Diff reads too many nodes
> -------------------------
>
> Key: OAK-2345
> URL: https://issues.apache.org/jira/browse/OAK-2345
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: core, mongomk
> Affects Versions: 1.0.8, 1.1.2, 1.1.3
> Reporter: Marcel Reutegger
> Assignee: Marcel Reutegger
> Fix For: 1.0.9, 1.1.4
>
>
> DocumentNodeStore.diffManyChildren() may read too many nodes when there is an
> inactive cluster node with an old _lastRev on the root document. This is a
> regression introduced with the fix for OAK-2232.
> The fix assumes an inactive cluster node does not have a revision range with
> an old revision seen at a current timestamp. The DocumentNodeStore will in
> fact purge revisions from the range in the RevisionComparator after an hour.
> But on startup the first background read may populate the RevisionComparator
> with a revision, which is potentially very old (e.g. if the clusterId is not
> used anymore).
