Support overloading of accumulate functions: Add int (or long) based sum's, int based avarage's, etc
-----------------------------------------------------------------------------------------------------
Key: JBRULES-1075
URL: http://jira.jboss.com/jira/browse/JBRULES-1075
Project: JBoss Rules
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Drl Parser/Builder
Affects Versions: 4.0.0.GA
Reporter: Geoffrey De Smet
Assigned To: Edson Tirelli
Priority: Minor
Fix For: FUTURE
TTP nl10 solver has about a 3% performance increase when switching from sumDouble to sumLong (and possibly a bit more when switching to sumInteger)
There are 2 ways I see to implement this:
1) Force the user to explicitly declare he wants to use an integer based sum and add a sumInteger.
This is not so user-friendly. This is what I 've done in the patch.
2) Support overloading of accumulate functions based on the function arguments.
AFAIK drl is strongly typed (at least with the java dialect), so it should be theoretically possible for the drl parser to see
sum($myInteger)
and bind it to SumIntegerAccumulateFunction,
while binding
sum($myInteger.doubleValue())
to SumDoubleAccumulateFunction.
And added advantage is that the drl compiler will also mark some bugs as compiler errors. For example
sum($myString)

CLONE -Deadlock when logging trace
----------------------------------
Key: JBAS-4514
URL: http://jira.jboss.com/jira/browse/JBAS-4514
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: chris effenberger
Assigned To: Scott M Stark
SourceForge Submitter: genman .
This was caused when trace was enabled. I imagine it
was caused by the classloader trying to load a class
while it was being rendered (?) to disk. Probably not
a big issue, unless trace-logging is enabled.

[JBoss JIRA] Created: (JBCLUSTER-140) Examine need for a distributed service registry outside the AS

Examine need for a distributed service registry outside the AS
--------------------------------------------------------------
Key: JBCLUSTER-140
URL: http://jira.jboss.com/jira/browse/JBCLUSTER-140
Project: JBoss Clustering
Issue Type: Sub-task
Security Level: Public (Everyone can see)
Reporter: Brian Stansberry
Assigned To: Brian Stansberry
Fix For: Q3Y6
Is something like DRM needed outside the AS? If it is, do we want to use the JBoss Cache based version (creates JBC dependency.)
DRM is used in two ways:
1) To maintain a distributed registry of remote invocation targets.
2) To maintain a distributed registry of services, which is done by having the service register a meaningless token under its key rather than a target. This is used by HASingleton.
Need to examine whether this kind of thing is needed by Messaging, or whether simple listening for view changes is sufficient. Listening for view changes could be sufficient if each group member knew how to create a Remoting InvokerLocator for the other members based on the JGroups Address. But, this presupposes use of consistent ports across the cluster, and that the IP address used by JGroups is the one that Messaging traffic should use.
