Subject [jira] [Created] (JCR-3345) ACL evaluation may return non-fresh results
Date Fri, 15 Jun 2012 16:02:42 GMT
Julian Reschke created JCR-3345:

             Summary: ACL evaluation may return non-fresh results
                 Key: JCR-3345
                 URL: https://issues.apache.org/jira/browse/JCR-3345
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core, security
    Affects Versions: 2.6
            Reporter: Julian Reschke
         Attachments: JCR-3345.test.patch

It appears that changes to access control entries are not always visible right away; in particular
not to the session that caused them.

EntryCollectorTest has recently been extended to run the existing set of tests under load
as well, and occasionally we see tests failing because of ACEs not yet being returned.

Increasing the load (see attached patch for the test) seems to make it easier to reproduce.

The underlying reason might be that this involves multiple sessions to be in sync.

Note that the cache in CachingEntryCollector doesn't seem to be the cause; disabling it by
commenting out all write operations to the cache (making everything a cache miss) doesn't
change the outcome.
