Making -1 default for Hot Rod server idle timeout?
by Galder Zamarreno
Hi all,
I was reading this thread (http://community.jboss.org/message/543377#543377) and was wondering whether idle timeout for Hot Rod should by default be -1. As I explained in the past, this parameter is used to handle any misbehaving clients that might be sending incomplete requests. Without an idle timeout, we couldn't catch those rogue clients.
However, this shouldn't really be the norm. If there's any suspicion of such things going on, users could restart the server with a positive idle timeout and iron out any issues.
Besides, it's pretty clear that the majority of users will be using one of the existing Hot Rod clients and hence the likelihood of seeing such issues is low.
Thoughts?

Oh bugger, had forgotten of that and V is completely out of our control. Hmmm, that's a bummer.

Maven build problems with EC2 demo
by Noel OConnor
Hi,
I'm trying to fix the assembly stage of the EC2 demo and I'm hitting a brick
wall due to my limited maven knowledge.
The EC2 demo builds two artifacts, a JAR file containing the demo code and a
WAR file which is a basic UI.
Both compile fine but when it comes to assembly into the infinispan-all.zip
the jars that both of these depend on are not bundled in the modules/lib and
the war is just a renamed copy of the jar.
The correctly assembled war is present in the demo/ec2/target directory but
the war contained in infinispan-all.zip is just a renamed copy of the jar.
Has anybody got some time to take a look ?
cheers

Infinispan GUI demo not building after maven repo changes
by galder＠redhat.com
Hi,
FAO jboss-dev list: Why wasn't apache-log4j/log4j group ported to new nexus repo? What are other projects depending on log4j 1.2.15 doing about this?
If you wipe your maven2 repo, you'll find that GUI demo does not build and this is related to the maven repo changes. Basically, the GUI demo depends on log4j 1.2.15 but we're not using the default one. Instead we're depending on http://repository.jboss.org/maven2/apache-log4j/log4j/1.2.15/
Now, the reason for that I suspect is the fact that if you depend on the standard log4j 1.2.15, you get dependency failures like this:
Missing:
----------
1) com.sun.jdmk:jmxtools:jar:1.2.1
Try downloading the file manually from:
http://java.sun.com/products/JavaManagement/download.html
Then, install it using the command:
mvn install:install-file -DgroupId=com.sun.jdmk -DartifactId=jmxtools -Dversion=1.2.1 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.sun.jdmk -DartifactId=jmxtools -Dversion=1.2.1 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.infinispan:infinispan-gui-demo:jar:4.1.0-SNAPSHOT
2) log4j:log4j:jar:1.2.15
3) com.sun.jdmk:jmxtools:jar:1.2.1
2) com.sun.jmx:jmxri:jar:1.2.1
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=com.sun.jmx -DartifactId=jmxri -Dversion=1.2.1 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.sun.jmx -DartifactId=jmxri -Dversion=1.2.1 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.infinispan:infinispan-gui-demo:jar:4.1.0-SNAPSHOT
2) log4j:log4j:jar:1.2.15
3) com.sun.jmx:jmxri:jar:1.2.1
----------
2 required artifacts are missing.
for artifact:
org.infinispan:infinispan-gui-demo:jar:4.1.0-SNAPSHOT
----------
As http://unitstep.net/blog/2009/05/18/resolving-log4j-1215-dependency-probl... explains, these appear to be optional dependencies that log4j should have set. Issues like this might explain why we ended up building and putting our own 1.2.15 version in the old repository.
The point is, what do we do about it? Any particular reason why the demo depends on version 1.2.15?

No idea tbh. I'll try to upgrade and see what happens. Bill, should we be upgrading to 2.0-beta-2?

R: Re: Removing dependencies from parent
by Sanne Grinovero
I'll be careful and propose a patch for review. I think it's worth to take
the risk better sooner than later ;) as I currently have to define several
exclusions in my app to prevent a jumbo package of unused jars.
Cheers,
Sanne

Yeah I'm fine with this, but these deps are needed by core and all of the
other modules in turn depend on core.

thoughts on RemoteCacheStore
by Mircea Markus
Hi,
1. Do we want this to be a CacheStore or CacheLoader only? Looking at TcpDelegatingCacheLoader it also does puts, guess we want to preserve the same behaviour - or?
2. load/loadAll/loadAllKeys operations cannot be implemented (hotrod does not support getKeys, and even so that would potentially be too costly)
3. at chacheStore level we have InternalCacheEntry, whilst RemoteCache operates with the actual key/value operations. This means that (at least on get) the expiration information is lost.
cheers,
Mircea
