Thomas Mueller commented on JCR-3547:
-------------------------------------
The patch looks good, thanks!
Because it's quite a big change, I think somebody else should have a look as
well, specially the changes in the RepositoryContext and RepositoryImpl.
I also think it's a good idea to run the GC tests serially, but I wonder why
they didn't fail before when running concurrently, if they actually accessed
the same repository concurrently? Or don't they access the same repository? But
then they should still be able to run concurrently, right?

> URL: https://issues.apache.org/jira/browse/JCR-3547
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core
> Affects Versions: 2.4, 2.5
> Reporter: Shashank Gupta
> Attachments: GarbageCollector.java.patch,
> GC_prevent_concurrent_run_app2.patch, GC_prevent_concurrnet_run_app1.patch

> In mark phase, GC updates store.updateModifiedDateOnAccess with current time,
> so that datastore updates record’s lastModified timestamp upon subsequent
> read/scan.
> But GC doesn't reset it to 0. So even after GC completes, datastore will
> continue updating lastModified timestamp on read invocations and it will have
> performance impact.
