Subject [jira] Created: (JCR-188) Item states cached in UpdatableItemStateManager not discarded on logout
Date Tue, 16 Aug 2005 13:37:17 GMT
Item states cached in UpdatableItemStateManager not discarded on logout
-----------------------------------------------------------------------

         Key: JCR-188
         URL: http://issues.apache.org/jira/browse/JCR-188
     Project: Jackrabbit
        Type: Improvement
  Components: core  
    Reporter: Edgar Poce
    Priority: Minor


The SessionItemStateManager disposes only the TransientItemStateManager but not the UpdatableItemStateManager.
The latter doesn't release the resources and the cached items keep listening the overlayed
state events until the ReferenceMap do its magic. According to my tests in certain circumstances
it slows down jackrabbit very much. 

In the charts you can see the time it takes to jackrabbit to save each child node. The first
test uses a single session and the second creates a new session for each added node.

The patch I attach makes both tests take the same time. Opinions?
