Re: Jackrabbit 1.0 RC3 and references to versions

[Marcel Reutegger]

Hi Alvaro,

thanks for testing the rc3 release of jackrabbit.
I've slightly rewritten your test case and added it to the 
o.a.j.core.query.DerefTest test class in jackrabbit (I hope you don't 
mind...)

The test runs fine in trunk also against the rc3.

Could you please check that you are working with a clean index. rc3 is 
not 100% compatible with any previous 'release'. You have to delete all 
the indexes and let jackrabbit re-index the workspaces.
If I remember correctly this is also mentioned in the release notes, but 
I'm not sure.

regards
 marcel

Hi all,
 I have downloaded jackrabbit-1.0-rc3 and tested with my application. 
Almost everything works fine but i have discovered a problem with 
jcr:deref queries (yes I am "jcr:deref-boy"  :- )).
In my application there are several nodes that have a reference property 
to a version of a particular node (actually a reference to 
jcr:frozenNode). Prior to 1.0-rc3 version works fine, but with the last 
release a query searching for this nodes returns 0 results.
 I don't know if it is correct to use references to nodes in the version 
workspace or it is a problem of the Query Manager.

I have tested it with version 0.9-rc1-incubating and with some 
house-made versions and it worked well.

Here is a a JUnit method that tests this issue:


   public void testVersionDerefSearch() throws Exception {              
Session currentSession = JCRUtil.currentSession();
       Node myRootNode = currentSession.getRootNode().addNode("root");
       currentSession.save();
       try {
           Node referenced = myRootNode.addNode("referenced");           
           referenced.addMixin("mix:versionable");
           currentSession.save();
           Version version = referenced.checkin();
           Node referencedVersionNode = version.getNode("jcr:frozenNode");
           Value referenceValue = 
currentSession.getValueFactory().createValue(referencedVersionNode);
           Node referencer  = myRootNode.addNode("referencer");
           referencer.setProperty("aReference",referenceValue);
           currentSession.save();
           String 
query="/"+myRootNode.getPath()+"/[EMAIL PROTECTED]/jcr:deref(@aReference,'*')"; 

           QueryManager qm = 
currentSession.getWorkspace().getQueryManager();
           Query q = qm.createQuery(query, Query.XPATH);
           QueryResult qr =  q.execute();
           NodeIterator ni = qr.getNodes();
           assertEquals("Must find one result in query",1,ni.getSize());
           while (ni.hasNext()) {
               Node node = (Node) ni.next();
               
assertTrue(node.getProperty("jcr:frozenUuid").getString().equals(referenced.getUUID())); 

           }                  } finally {
           myRootNode.remove();
       }
   }
