[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Re: HASingleton and partition merges

[bstansberry@jboss.com]

The complication with backporting is:

1) New config flag == change to mbean interface
2) Change to interface is illegal in a CP, hence have to create a new interface and new probably a trivial new class that exposes it (I'm too lazy to go beyond a StandardMBean approach.
3) Don't want to change deploy-hasingleton-service.xml to use this new class/interface, as that's too big a change for a CP (changing config file could break people who've already altered it.)

All this is resolvable, it's just extra hassle.  And the result is that a fix will be in the codebase, but to take advantage of it users will have to make manual configuration changes.


(BTW, users can't set the flag to true for HA-JMS per se.  They can set it to true for the jboss.ha:service=HASingletonDeployer service, which in essence means setting it to true for the entire deploy-hasingleton directory.  If they wanted the behavior only for HA-JMS and had other deploy-hasingleton content, they'd have to separate the content into another dir and create a parallel HASingletonController to deploy that dir.)
