           Summary: helma swarm funktioniert nicht mit aktuellen helma
           Product: Helma
           Version: 1.6.2
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Extensions
        AssignedTo: helma-dev@...
        ReportedBy: philipp.moser@...


Soeben auf twoday getestet. Die aktuelle helma Version funktioniert nicht mit
der aktuellen swarm Version
(https://dev.helma.org/svn/helma/extensions/helmaswarm/trunk/).

Wenn man den swarm aufdreht
{{{
cluster             = true
clusterWorkerID     = helma-lb-01
cacheImpl           = helma.swarm.SwarmCache
sessionManagerImpl  = helma.swarm.SwarmSessionManager
idGeneratorImpl     = helma.swarm.SwarmIDGenerator
swarm.name          = MySwarm
swarm.jgroups.stack = tcp
swarm.conf          = /home/helma/HelmaClusterConfig/swarm.conf
}}}

Jetty antwortet immer mit einem 500 Fehler:
{{{
<html><head><title>Error 500 cacheNode</title></head><body>
<h2>HTTP ERROR: 500</h2><pre>cacheNode</pre>
<p>RequestURI=/helma/twoday_net/www/</p>
<p><i><small><a href="http://jetty.mortbay.org">Powered by
Jetty://</a></small></i></p>
</body></html>
}}}

Sorry, I can't reproduce this. Can you provide a stack trace, or a test app?

Ok, I found the problem. HelmaSwarm just needs to be recompiled to work.

I'll put out a HelmaSwarm 1.0.1 which also has the discard_delivered_msgs=true
for pbcast.NAKACK to fix the potential memory leak you came up with:

Fixed with release 1.0.1 of helmaswarm:

http://adele.helma.org/download/helma/contrib/helmaswarm/

there's one remaining problem, though: If a swarm mixes instances of helma
1.6.2 and earlier 1.6 releases, initial session transfer at application startup
time will not work between the two. This is because of an incompatible change
in the helma 1.6.2 session class.

I'm sorry about this. There's not much I can do about it except pay more
attention to serialization issues in the future.

Yes, however the bug is fixed already.
