[jboss-jira] [JBoss JIRA] Assigned: (JGRP-1084) MessageDispatched to have marshalling callback after real_dest have been calculated

MessageDispatched to have marshalling callback after real_dest have been calculated ----------------------------------------------------------------------------------- Key: JGRP-1084 URL: https://jira.jboss.org/jira/browse/JGRP-1084 Project: JGroups Issue Type: Feature Request Reporter: Galder Zamarreno Assignee: Vladimir Blagojevic Fix For: 2.9 A week ago filled I ISPN-237 jira in order for dist commands that should only affect the local machine not to go remove. While investigating your stress test, I've found out that JGroups' MessageDispatcher.castMessage already does that! if(tmp != null && tmp.getOpt(Channel.LOCAL).equals(Boolean.FALSE)) { if(local_addr == null) { local_addr=tmp.getAddress(); } if(local_addr != null) { real_dests.removeElement(local_addr); } } That code empties the real_dests if the target is the local address. So, you're probably wondering why I filled ISPN-237? It's because marshalling happens before the code above gets executed. In fact, it happens at the beginning of ReplicationTask.call() and the JGroups optimization happens when castMessage() is called from ReplicationTask.call(). So, I think my fix for ISPN-237 is not optimal. JGroups already knows when the call should stay local, so ISPN should need to do this calculation again, it's wasteful code. The real fix would be to somehow be able to do marshalling only if the code in MessageDispatcher.castMessage() said that real_dests was not empty. Bela, do you think JGroups could be enhanced to have a callback after the code shown above where we can invoke marshalling?
