Subject [jira] Created: (DIR-178) Reliable hang of DS during query

Reliable hang of DS during query
--------------------------------

         Key: DIR-178
         URL: http://issues.apache.org/jira/browse/DIR-178
     Project: Directory
        Type: Bug
 Environment: DS 0.9.3, Windows, JDK 1.5
    Reporter: Jörg Henne
 Assigned to: Alex Karasulu 


When running the attached test, the directory server hangs after executing a slew of operations
when searching for objects.

First of all, some background on the test case:
The attached test case (in the form of an exported eclipse project) is, unfortunately, based
on quite a few classes. They are part of a project I am currently working on: an object to
ldap mapper with a similar approach as castor for XML or hibernate for RDBMS, albeit a lot
more modest in complexity (I'll, hopefully, one day be able to open-source it - for now it
is still much to immature). I have supplied all that stuff mainly for your reference.

To run the test case, please make sure that the constant "URL" in LDAPDirectoryTest points
to a valid directory. The URL the context points to must exist. It will, however, subsequently
create lots of nodes below it.

The hang seems to be related to some kind of deadlock, since it doesn't occur once the whole
test is run via a single context only. To achieve this, set the constant "ONE_CONTEXT" to
true (each LDAPDirectory uses its own set of contexts).

If you have any problems running the test, please don't hesitate to contact me.
