Bug 745917 (EDG-13)

Hmmm, Martin, have you verified that the nodes are joining in a cluster? Any errors in the log?...etc.

Nodes joined in the cluster, no errors seen anywhere but will check once again.

Attaching log files with TRACE logging for both servers. I tried to put a key=key1 with value=value1 to node1 and retrieve it from node2.

The following configuration was used for both nodes:

{code:xml}
<cache-container name="default" default-cache="default" listener-executor="infinispan-listener">
                <transport executor="infinispan-transport" lock-timeout="240000"/>
                <distributed-cache owners="2" virtual-nodes="512" l1-lifespan="0" mode="SYNC" remote-timeout="30000" name="default" start="EAGER" batching="false" indexing="NONE">
                    <locking isolation="REPEATABLE_READ" striping="false" acquire-timeout="30000" concurrency-level="1000"/>
                    <transaction mode="NON_XA"/>
                    <rehashing enabled="true" timeout="600000"/>
                </distributed-cache>
                <distributed-cache mode="SYNC" name="namedCache"/>
            </cache-container>
{code} 

As a result of ISPN-1206, an issue has been found in AS7 which is leading to this problem:  AS7-1518

I verified this with the new build (JBossAS 7.1.0.Alpha1-SNAPSHOT from today, EDG6 SNAPSHOT including this JBossAS, Infinispan 5.0.0.FINAL) and it works fine already. Both the functional tests and ispncon test. Galder, we can close this IMHO.

It seems the issue appeared again. I tried EDG using JBossAS 7.0.1.Final and Infinispan 5.0.0.Final and performed the same ispncon test as before which failed. Also our functional tests for memcached are failing: https://hudson.qa.jboss.com/hudson/view/EDG6/job/edg-60-functional-tests-ispn-arq/95/#showFailuresLink

This was already working on 2011-08-12 with JBossAS snapshot from that day and Infinispan 5.0.0.Final. Today, I also tried JBossAS snapshot from 2011-08-12 with todays Infinispan snapshot (5.1.0-SNAPSHOT) and this worked well as well. So it's not in Infinspan itself but probably in JBossAS integration.

I ran our testsuite with a few more builds based on JBossAS with various HEADs. I found out that this problem is caused by this commit: https://github.com/jbossas/jboss-as/commit/a2fd1dbe6a1609f8532e53f571b22464d67a2833. The default cache for memcached is now named memcachedCache and this commit somehow overlooks it.

A bug in AS 7 code?

Paul, the commit I mentioned is exactly the opposite to the one which fixed AS7-1518 (which led to this JIRA being fixed): https://github.com/pferraro/jboss-as/commit/2122489b00e19e5afef6c95586329c0fcd04465d

OK - I think the source of the confusion is a semantic difference between the "default-cache" in AS7 and the <default> cache configuration concept in Infinispan.  In AS7, caches do not inherit their configuration from the cache identified as the default cache.  Instead, their configuration is inherited from an internal configuration definition that varies based on the cache mode.  The point of this AS-specific behavior is to simplify the process of switching default cache configurations for a given container, without needing to worry about inheritance.
Consequently, in AS7, calls to EmbeddedCacheManager.defineConfiguration(String, Configuration) should not expect inherit the configuration of the "default-cache".  Judging from your configuration above, it looks like this is what you're expecting.  

To be more specific, if the EDG code should use the 3-arg method:
manager.defineConfiguration(name, templateCache, configuration);
Where templateCache is the name of the cache configuration from which you'd like to inherit.

Thank you for the explanation, Paul. So this is not a real issue and we can get Infinispan to work by defining a named cache called "memcachedCache" in standalone.xml. The memcached module will use this cache as its default one.

Paul, haven't checked javadoc but can you make sure that differences in defineConfiguration semantics between AS7 and Infinispan are documented AS7's defineConfiguration implementation if they're not already?
