Alexander Klimetschek updated SLING-2493:
-----------------------------------------
Affects Version/s: (was: JCR Resource 2.1.0)
> sling:vanityPaths: observation listener should be registered before initial
> scan to avoid missing changes
> ---------------------------------------------------------------------------------------------------------
>
> Key: SLING-2493
> URL: https://issues.apache.org/jira/browse/SLING-2493
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Reporter: Alexander Klimetschek
> Priority: Minor
> Attachments: SLING-2493.patch
>
>
> MapEntries [0] does first a scan in doInit() and then registers the event
> listener for sling:vanityPath nodes. Now if a observation event comes in
> between that, it gets lost - the old content was read in the initial scan and
> is cached.
> It looks like we had such a case while both bundle and content were updated
> "at the same time". Possibly the registerService() method could be blocked
> for a while if many other services are restarted in such a update scenario
> involving multiple bundles.
> I think the observation listener for such cases should always be registered
> *before* the initial scan.
