[JBoss JIRA] Created: (JGRP-457) Optimization: make threads return immediately if NAKACK has another active thread for the same sender

Optimization: make threads return immediately if NAKACK has another active thread for the same sender
-----------------------------------------------------------------------------------------------------
Key: JGRP-457
URL: http://jira.jboss.com/jira/browse/JGRP-457
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assigned To: Bela Ban
Priority: Minor
Fix For: 2.5
In NAKACK, when a thread places a message for sender S into the NakReceiverWindow NRW, it subsequently acquires a lock on NRW (lock by sender) and removes as many messages as possible and passes them up.
If many threads do this at the same time, all threads but one are blocked, and - when finally unblocked - usually return. This causes context switches and possibly cache flushing, so a better way would be to have the threads check whether another thread is already removing messages using a CAS operation *before* acquiring the lock.
The effect should be that no threads will wait on the lock unnecessarily, and thus fewer context switches, and more threads available to the pool.

[JBoss JIRA] (AS7-4657) Add resolve-expressions param to operation read-resource
by Michael Voegele (JIRA)
Michael Voegele created AS7-4657:
------------------------------------
Summary: Add resolve-expressions param to operation read-resource
Key: AS7-4657
URL: https://issues.jboss.org/browse/AS7-4657
Project: Application Server 7
Issue Type: Feature Request
Reporter: Michael Voegele
When reading a resource remotely, it would be nice to have the possibility to have expressions resolved.
Following does of course not work, as the code runs in a separate jvm.
{code:java}
private void readRecursive(ModelNode modelNode, String modelNodeName, Map<String, Object> map) {
switch (modelNode.getType()) {
...
case EXPRESSION:
// this would be great but won't work as it runs in a different jvm
// ModelNode expression = modelNode.resolve();
// readRecursive(expression, modelNodeName, map);
map.put(modelNodeName, modelNode.asString());
break;
...
}
{code}
Therefore a param resolve-expressions for the read-resource operation would be good.

I had a look around and found this related (in fact the same) bug report:
https://issues.apache.org/bugzilla/show_bug.cgi?id=43327
Looks like it may have been fixed for IPv6 addresses other than link-local.
Link-local addresses are used often for running on a local network segment.
