[JBoss JIRA] Created: (JGRP-1193) Simplify RspFilter interface

by Vladimir Blagojevic (JIRA)

Simplify RspFilter interface ---------------------------- Key: JGRP-1193 URL: https://jira.jboss.org/jira/browse/JGRP-1193 Project: JGroups Issue Type: Task Affects Versions: 2.9, 2.8, 2.7 Reporter: Vladimir Blagojevic Assignee: Vladimir Blagojevic Fix For: 3.0 RspFilter interface although having only two methods in its contract has been a source of some confusion regarding the semantics of response filtering. In order to simplify and make response filtering semantics easier to understand and implement a new RspFilter has been proposed for 3.0. RspFilterResult responseReceived(Object response, Address sender); RspFilterResult is an enum with four states where each state is essentially a combination of two boolean variables: validResponse and needMoreResponses.

by Bela Ban (JIRA)

Harden merge ------------ Key: JGRP-1026 URL: https://jira.jboss.org/jira/browse/JGRP-1026 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.9 Make sure that no merge is ever left hanging, e.g. due to the crash of the merge coordinator after the initial phase. This could prevent furthur merges. Analyze the code and make sure that eventually merges are always completed or aborted. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-2211) StatefulKnowledgeSession leaves threads running

by Edson Tirelli (JIRA)

StatefulKnowledgeSession leaves threads running ----------------------------------------------- Key: JBRULES-2211 URL: https://jira.jboss.org/jira/browse/JBRULES-2211 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL, 5.0.0.FINAL Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 5.1.0.M1 Hi all, I've downloaded Drools fusion sample and started to make some changes to the code (first of all wipe out the UI so I can test it easier). I tried to get to a minimal set so I can run a console main class and see what happens but I am facing a strange behaviour. As soon as I start pushing events into the WorkingMemoryEntryPoint ("StockTick stream") a Thread - not daemonized since it blocks shutdown from ending - is spawned and this prevents my JVM from shutting down (obviously if I call System.exit(0) it will but I am avoiding this). I've tried both to halt and dispose the session that this entry point belongs but with no success. Does anyone know how could I get rid of this thread? ================== Hi Edson! as I've already mentioned I've modified the sample so, if you get the StockTick sample and replace the Main class this will run fine. The sample shuts down fine but as I saw it sets the JFrame uses frame.setDefaultCloseOperation( WindowConstants.EXIT_ON_CLOSE ); which in turn makes the trick. Below the code of my modified main class: package org.drools.examples.broker; import org.drools.KnowledgeBase; import org.drools.KnowledgeBaseConfiguration; import org.drools.KnowledgeBaseFactory; import org.drools.builder.KnowledgeBuilder; import org.drools.builder.KnowledgeBuilderFactory; import org.drools.builder.ResourceType; import org.drools.conf.EventProcessingOption; import org.drools.examples.broker.model.Company; import org.drools.examples.broker.model.CompanyRegistry; import org.drools.examples.broker.model.StockTick; import org.drools.io.ResourceFactory; import org.drools.runtime.StatefulKnowledgeSession; import org.drools.runtime.rule.WorkingMemoryEntryPoint; public class Main { private static final String RULES_FILE = "/broker.drl"; static StatefulKnowledgeSession session; static WorkingMemoryEntryPoint tickStream; /** * @param args */ public static void main(String[] args) throws Exception { // set up and show main window CompanyRegistry companies = new CompanyRegistry(); KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder(); try { builder.add( ResourceFactory.newInputStreamResource( Main.class.getResourceAsStream( RULES_FILE ) ), ResourceType.DRL); } catch ( Exception e ) { e.printStackTrace(); } if( builder.hasErrors() ) { System.err.println(builder.getErrors()); System.exit( 0 ); } KnowledgeBaseConfiguration conf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); conf.setOption( EventProcessingOption.STREAM ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( conf ); kbase.addKnowledgePackages( builder.getKnowledgePackages() ); session = kbase.newStatefulKnowledgeSession(); session.setGlobal( "services", new BrokerServices() { public void log(String message) { System.out.println(message); } }); for( Company company : companies.getCompanies() ) { session.insert( company ); } session.fireAllRules(); tickStream = session.getWorkingMemoryEntryPoint( "StockTick stream" ); for (int i=10;i>0;i--) { tickStream.insert(new StockTick("RHT", i*10, System.currentTimeMillis())); session.getAgenda().getAgendaGroup( "evaluation" ).setFocus(); session.fireAllRules(); } session.dispose(); session.halt(); System.out.println("Still running..."); } } regards, Rafael Ribeiro -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
