Subject [jira] Commented: (JS2-589) PermissionManagerImpl use of ThreadLocal for caching causes inconsistent results
Date Thu, 28 Sep 2006 18:25:51 GMT
    [ http://issues.apache.org/jira/browse/JS2-589?page=comments#action_12438520 ] 
            
David Sean Taylor commented on JS2-589:
---------------------------------------

So the threads are being reused by the application server. I assumed that the app server would
clear the thread local. Guess not.
The goal for the caching was to reuse permissions on a per request basis. Would it help if
we cleared the thread local cache at the end of the request pipeline?
Its either that or find a way to sync up the thread local caches...

> PermissionManagerImpl uses ThreadLocal for permission caching.  This means that once
the permissions are loaded for one thread (ex. thread 1), they are there until someone changes
the permissions using the PermissionManager (on that thread).  If permissions are edited on
another thread (thread 2), thread 1 never gets updated.  So permissions are inconsistent until
the portal is restarted.
