cluster feature - bug ?

Hi

I try to use cluster feature. I run two very simple applications. The first 
application create nodes. The second application delete nodes. If I run them 
separately, works fine. But if I run them simultaneously, sometimes  I get 
exceptions like this:

and repository doesn't work anymore. If I try to run it, I get exception when 
nodes are created:

The exception is thrown always for the same node(e.g. 33 nodes are created 
fine but when 34. is created exception is thrown)

If I remove the index directory, I get exception when repository is 
initialized:

I hope to have 1.3 ready for release already by the end of March,
assuming no unexpected delays with JCR-755 that's driving the release.

The fix for JCR-756 cluster issue was unfortunately too complex to be
included in the 1.2.3 patch release, and therefore we don't even have
a simple patch that you could apply yourself to the 1.2 release
branch. If you're interested, you can checkout and build the latest
svn trunk where the fix is already included. Note that such snapshot
builds should only be used for development and testing, not deployed
in production.

BR,

Jukka Zitting

Hi,

I noticed that the fix was postponed to version 1.3. Could someone tell me 
when 1.3 will be released and where I can find sources containing that fix ?

The fix to JCR-756 hasn't yet been applied to the 1.2 branch.

Dominique, could you isolate the JCR-756 fix from the 509624 commit
and apply it to the 1.2 branch?

Hi,

I can still reproduce that problem with version from branch 1.2
(http://svn.apache.org/repos/asf/jackrabbit/branches/1.2).
Did I check out correct sources ?

Re: cluster feature - bug ?

Posted by Dominique Pfister <do...@day.com>.

Hi Rafał,

just wanted to let you know that I could fix the problem you reported
(and some other problems as well!) thanks to the test classes you
provided:

  https://issues.apache.org/jira/browse/JCR-756

Your input was indeed very helpful to track down this issue, thanks again!

Kind regards
Dominique

Yes. The official 1.2.2 release built from that branch was just
approved and is on it's way to the Apache download mirrors. I'll send
the public release announcement tomorrow.

Re: cluster feature - bug ?

Posted by Dominique Pfister <do...@day.com>.

Hi Rafał,

The NullPointerException during Remove has been resolved in branch 1.2.2:

  https://issues.apache.org/jira/browse/JCR-712

As for the other exception(s), this looks like a concurrency issue,
that might be resolved
if the first one is. Anyway, thank you for the small, isolated test
applications that I will gladly test against the not yet released
1.2.2.

Kind regards
Dominique
