Wrong evaluation of rules and PseudoClock NPE
---------------------------------------------
Key: JBRULES-2457
URL: https://jira.jboss.org/jira/browse/JBRULES-2457
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 5.1.0.M1, 5.0.1.FINAL
Environment: Windows 7, Eclipse 3.4, Java 1.6.0_u18, JUnit 4
Reporter: Vítor Moreira
Assignee: Mark Proctor
I've got a DRL file, having the following rules:
- offline event for 3 minutes withou any online event meanwhile => send an offline notification
- online event after offline event (within 3 minute range) => send an online notification
I've also got an junit test:
- insert offline event
- pseudoclock advances 2m50s
- insert online event
- pseudoclock advances 15s
- check if there's any notification
And the result of the junit is:
1) NPE when clock advances 15s
java.lang.NullPointerException
at org.drools.util.LinkedList.remove(LinkedList.java:113)
at org.drools.common.Scheduler$DuractionJob.execute(Scheduler.java:71)
at org.drools.time.impl.PseudoClockScheduler$ScheduledJob.call(PseudoClockScheduler.java:219)
at org.drools.time.impl.PseudoClockScheduler.runCallBacks(PseudoClockScheduler.java:168)
at org.drools.time.impl.PseudoClockScheduler.advanceTime(PseudoClockScheduler.java:130)
2) When checking for a notification, it should have one online notification but has on offline notification
At the bottom of this issue, there are snippets of junit code and drools rule file.
Probably, the problem relies on Junit initialization code.

Ergonomics
----------
Key: JGRP-1052
URL: https://jira.jboss.org/jira/browse/JGRP-1052
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.0
The goal is to (a) reduce the number of properties needed and (b) determine the values dynamically.
Examples:
- Determine the best min/max size of a thread pool
- Find out what the best timeout values are for retransmission, e.g. based on average retransmission times
- Determine the optimal number of credits in FC
This is similar to the JVM setting where, starting with 1.5, the initial values can be set, but over time, the JVM dynamically changes them.
In the best case, a config contains only a list of protocols without any properties, and JGroups will figure out the correct values.

loading multiple sheets of single Excel book by one change-set xml
------------------------------------------------------------------
Key: JBRULES-2438
URL: https://jira.jboss.org/jira/browse/JBRULES-2438
Project: Drools
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: drools-core
Affects Versions: 5.0.1.FINAL
Reporter: Toshiya Kobayashi
Assignee: Mark Proctor
I'm trying to use rules via DecisionTable using change-set.
I wrote rules in multiple sheets of single Excel book.
Then I configured my change-set xml like:
...
<add>
<resource source='classpath:data/dtable.xls' type="DTABLE">
<decisiontable-conf input-type="XLS" worksheet-name="sheet1" />
</resource>
<resource source='classpath:data/dtable.xls' type="DTABLE">
<decisiontable-conf input-type="XLS" worksheet-name="sheet2" />
</resource>
</add>
...
But only rules of sheet1 were loaded.
As far as I observed source codes, KnowledgeAgentImpl.java puts resource into "Map<Resource, ResourceMapping> resources". But even if multiple resources are configured in change-set, it appears to me like those resources are considered as the same resource and eventually only one resource will be registered.

[JBoss JIRA] Created: (JBMESSAGING-1490) BridgeService should be JAAS aware

BridgeService should be JAAS aware
----------------------------------
Key: JBMESSAGING-1490
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1490
Project: JBoss Messaging
Issue Type: Feature Request
Affects Versions: 1.4.2.GA
Environment: n/a
Reporter: Nicholas Sayer
Assignee: Tim Fox
Priority: Optional
org.jboss.jms.server.bridge.BridgeService currently requires a username and password for the source and destination. It would be better if it could be configured with a JAAS login context name. This would allow username and password information to be set in, for example, a SecureIdentityLoginModule. For example:
<application-policy name = "JmsBridgeRealm">
<authentication>
<login-module code = "org.jboss.resource.security.SecureIdentityLoginModule" flag = "required">
<module-option name = "principal">${bridge.user}</module-option>
<module-option name = "userName">${bridge.user}</module-option>
<module-option name = "password">${bridge.encryptedPassword}</module-option>
<module-option name = "ignoreMissigingMCF">true</module-option>
<!-- it is a separate bug that you must set managedConnectionFactoryName to something regardless of setting ignoreMissingMCF to true -->
<module-option name = "managedConnectionFactoryName">jboss.nonexistent:service=NonExistent,name=NonExistent</module-option>
</login-module>
</authentication>
</application-policy>
There is undoubtedly a better way to accomplish this (probably to pass the JAAS context directly into the JMS connection factory used to vend connections for the bridge), but we're using this as a crude hack for now:
import java.util.Set;
import javax.security.auth.Subject;
import javax.security.auth.login.LoginContext;
import javax.security.auth.login.LoginException;
import javax.security.auth.login.CredentialNotFoundException;
import javax.resource.spi.security.PasswordCredential;
import org.jboss.jms.server.bridge.BridgeService;
public class JAASAwareBridgeService extends BridgeService {
private String sourceContext, targetContext;
public void setSourceLoginContext(String ctxName) { this.sourceContext = ctxName; }
public String getSourceLoginContext() { return this.sourceContext; }
public void setTargetLoginContext(String ctxName) { this.targetContext = ctxName; }
public String getTargetLoginContext() { return this.targetContext; }
public void start() throws Exception {
setupSourceCredentials();
setupTargetCredentials();
super.start();
}
private void setupSourceCredentials() throws LoginException {
PasswordCredential pc = getPasswordCredential(this.sourceContext);
super.setSourceUsername(pc.getUserName());
super.setSourcePassword(new String(pc.getPassword()));
}
private void setupTargetCredentials() throws LoginException {
PasswordCredential pc = getPasswordCredential(this.targetContext);
super.setTargetUsername(pc.getUserName());
super.setTargetPassword(new String(pc.getPassword()));
}
private static PasswordCredential getPasswordCredential(String contextName) throws LoginException {
LoginContext ctx = new LoginContext(contextName);
ctx.login();
Subject s = ctx.getSubject();
Set<PasswordCredential> creds = s.getPrivateCredentials(PasswordCredential.class);
if (creds.isEmpty())
throw new CredentialNotFoundException("Login context '" + contextName + "' subject has no PasswordCredential");
return creds.iterator().next(); // get 1st
}
}

[JBoss JIRA] Created: (JBMESSAGING-1478) inconsistent test suite performance

inconsistent test suite performance
-----------------------------------
Key: JBMESSAGING-1478
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1478
Project: JBoss Messaging
Issue Type: Bug
Components: Tests and Performance
Affects Versions: 1.4.0.SP3.CP04
Reporter: Aleksandar Kostadinov
Assignee: Tim Fox
I see inconsistent performance running the JBM test suite. Here I have 2 builds on the same physical machine (windows), using local disk storage so environment should be pretty stable.
The mysql database is shared but I doubt it is the culprit.
I run the test suite with the following options:
property( name: "functional.tests.database", value: dbname )
property( name: "stress.tests.database", value: dbname )
property( name: "clustering.tests.database", value: dbname )
property( name: "test.target", value: "report" )
property( name: "test.bind.address", value: properties["env.MYTESTIP_1"] )
property( name: "jboss.messaging.groupname", value: properties["env.BUILD_TAG"])
property( name: "jboss.messaging.datachanneludpaddress", value: properties["env.MCAST_ADDR"] )
property( name: "jboss.messaging.controlchanneludpaddress", value: properties["env.MCAST_ADDR"] )
Are there any other options I can add to increase isolation from other processes in the same LAN?
Would you be able to look at these 2 builds and based on the logs, say why is the first one taking longer and eventually timeout?
