Accumulate should not call getResult() more then necessary
----------------------------------------------------------
Key: JBRULES-1471
URL: http://jira.jboss.com/jira/browse/JBRULES-1471
Project: JBoss Drools
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Reteoo
Reporter: Geoffrey De Smet
Assigned To: Edson Tirelli
Fix For: 5.0.0-M1
For this rule:
rule "roomCapacityTooSmall" // TODO it takes 50-90% of the performance of drools-solver
when
$period : Period();
$room : Room($capacity : capacity);
$totalStudentSize : Number(intValue > $capacity) from accumulate(
Exam(period == $period, room == $room, $studentSize : topicStudentSize),
sum($studentSize)
);
...
end
Outside drl, I update 2 out of 700 Exam objects and call fireAllRulesAndCalculateDecisionScore.
The drl never changes an Exam. Period and Room never change.
That results into this log:

There are 4 accumulate calls and 4 reverse calls. That might be accurate.
There are 8 getResult calls, that should only be 1.
Also, the getResult method creates a new Double instance each time:
return new Double( data.total );
It might be better to do
return Double.valueOf(data.total);
to allow the JVM to hot spot optimize it.

[JBoss JIRA] Created: (JBRULES-946) RuleBase serialization fails with StackOverflowError

RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: http://jira.jboss.com/jira/browse/JBRULES-946
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.0.MR2
Reporter: Alexandre Gattiker
Assigned To: Mark Proctor
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly fine and working.

[JBoss JIRA] Created: (JBMESSAGING-1490) BridgeService should be JAAS aware
by Nicholas Sayer (JIRA)
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
by Aleksandar Kostadinov (JIRA)
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?
