[JBoss JIRA] Created: (JBRULES-2318) (Un)Marshalling should respect times of scheduled activations

by Maciej Prochniak (JIRA)

(Un)Marshalling should respect times of scheduled activations ------------------------------------------------------------- Key: JBRULES-2318 URL: https://jira.jboss.org/jira/browse/JBRULES-2318 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-core (expert), drools-core (fusion) Affects Versions: 5.1.0.M1 Reporter: Maciej Prochniak Assignee: Mark Proctor Currently, ScheduledAgendaItems are marshalled as normal activations. In result, after unmarshalling these items are fired immediately (after fireAllRules). This affects rules with specified duration and also evaluation of temporal operators in fusion -- 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-2381) NPE during usage after serialize/deserialize

by Justin Waugh (JIRA)

NPE during usage after serialize/deserialize -------------------------------------------- Key: JBRULES-2381 URL: https://jira.jboss.org/jira/browse/JBRULES-2381 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Environment: Windows XP / Server 2003, JDK 1.6 Reporter: Justin Waugh Assignee: Mark Proctor Attachments: test.zip In our application we are often removing and adding new rules. We also have a requirement to serialize state so that we can continue across restarts. We've seen a few problems related to the state of the knowledgebase after serializing/deserializing related to removing rules. Both are NPE's, and from debugging into Drools, both seem to be a case of a deserialized transient value not being wired up correctly. In one case the reader field of ClassFieldReader is not wired, so the InternalReadAccessor is null, and in the other the expression field of EvalCondition is left null. I have not been able to reproduce in a simple test case the first problem, though it is easily reproduceable in our live system, but I was able to reproduce the second, and I've attached a test case to demonstrate it. Both only happen with the combination of removing rules and serialization/deserialization. If the rules are never removed, the problems do not exhibit themselves. Here are the 2 stack traces: java.lang.NullPointerException at org.drools.base.ClassFieldReader.getValueType(ClassFieldReader.java:96) at org.drools.reteoo.CompositeObjectSinkAdapter.addObjectSink(CompositeObjectSinkAdapter.java:98) at org.drools.reteoo.ObjectSource.addObjectSink(ObjectSource.java:143) at org.drools.reteoo.AlphaNode.attach(AlphaNode.java:116) at org.drools.reteoo.AlphaNode.attach(AlphaNode.java:120) at org.drools.reteoo.builder.BuildUtils.attachNode(BuildUtils.java:160) at org.drools.reteoo.builder.PatternBuilder.attachAlphaNodes(PatternBuilder.java:295) at org.drools.reteoo.builder.PatternBuilder.attachPattern(PatternBuilder.java:117) at org.drools.reteoo.builder.PatternBuilder.build(PatternBuilder.java:70) at org.drools.reteoo.builder.GroupElementBuilder$AndBuilder.build(GroupElementBuilder.java:126) at org.drools.reteoo.builder.GroupElementBuilder.build(GroupElementBuilder.java:73) at org.drools.reteoo.builder.ReteooRuleBuilder.addSubRule(ReteooRuleBuilder.java:153) at org.drools.reteoo.builder.ReteooRuleBuilder.addRule(ReteooRuleBuilder.java:126) at org.drools.reteoo.ReteooBuilder.addRule(ReteooBuilder.java:118) at org.drools.reteoo.ReteooRuleBase.addRule(ReteooRuleBase.java:362) at org.drools.common.AbstractRuleBase.addRule(AbstractRuleBase.java:618) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:662) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:290) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:488) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25) java.lang.NullPointerException at org.drools.rule.EvalCondition.createContext(EvalCondition.java:110) at org.drools.reteoo.EvalConditionNode.createMemory(EvalConditionNode.java:231) at org.drools.common.ConcurrentNodeMemories.createNodeMemory(ConcurrentNodeMemories.java:96) at org.drools.common.ConcurrentNodeMemories.getNodeMemory(ConcurrentNodeMemories.java:75) at org.drools.common.AbstractWorkingMemory.getNodeMemory(AbstractWorkingMemory.java:1534) at org.drools.reteoo.EvalConditionNode.doRemove(EvalConditionNode.java:263) at org.drools.common.BaseNode.remove(BaseNode.java:95) at org.drools.reteoo.RuleTerminalNode.doRemove(RuleTerminalNode.java:360) at org.drools.common.BaseNode.remove(BaseNode.java:95) at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:248) at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:366) at org.drools.common.AbstractRuleBase.removeRule(AbstractRuleBase.java:712) at org.drools.common.AbstractRuleBase.removePackage(AbstractRuleBase.java:640) at org.drools.impl.KnowledgeBaseImpl.removeKnowledgePackage(KnowledgeBaseImpl.java:166) -- 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

So the node takes a configuration of a changeset.

The test dowloads a binary package from guvnor, containing one trivial rule. Then it creates a StatefulKnowledgeSession and insert 500 facts. The drl file uploaded on guvnor is: -------------------------- package mytest.debug.rules declare PerUserCount num : long profile : String end rule "Event" dialect "java" when e: PerUserCount() then System.out.println("Possible spammer [p=" + e.getProfile() + "] : count = " + e.getNum()); end ---------------------------- When calling fireAll, i get an exception. Note that: 1) The exception does not show up right away-- it only comes after some of those facts got processed 2) If i change the dialect from default 'mvel" to "java" it works fine: Exception in thread "main" java.lang.NoClassDefFoundError: mytest/debug/rules/PerUserCount at ASMAccessorImpl_7377369041259611028980.getValue(Unknown Source) at org.mvel2.optimizers.dynamic.DynamicGetAccessor.getValue(DynamicGetAccessor.java:66) at org.mvel2.ast.ASTNode.getReducedValueAccelerated(ASTNode.java:99) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:102) at org.mvel2.compiler.ExecutableAccessor.getValue(ExecutableAccessor.java:41) at ASMAccessorImpl_7157329411259611028970.getValue(Unknown Source) at org.mvel2.optimizers.dynamic.DynamicGetAccessor.getValue(DynamicGetAccessor.java:66) at org.mvel2.ast.ASTNode.getReducedValueAccelerated(ASTNode.java:99) at org.mvel2.MVELRuntime.execute(MVELRuntime.java:85) at org.mvel2.compiler.CompiledExpression.getValue(CompiledExpression.java:107) at org.mvel2.MVEL.executeExpression(MVEL.java:978) at org.drools.base.mvel.MVELConsequence.evaluate(MVELConsequence.java:87) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:934) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:885) at org.drools.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1086) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:660) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:627) at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:183) at com.drools.debug.Test.runIteration(Test.java:132) at com.drools.debug.Test.startTest(Test.java:73) at com.drools.debug.Test.main(Test.java:196) Caused by: java.lang.ClassNotFoundException: mytest.debug.rules.PerUserCount at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:402) ... 23 more -- 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
