[JBoss JIRA] Created: (JBRULES-2079) ruleBase.addPackage(packageBuilder.getPackage()); should fail-fast with a clear error message if the packageBuilder has any errors

by Geoffrey De Smet (JIRA)

ruleBase.addPackage(packageBuilder.getPackage()); should fail-fast with a clear error message if the packageBuilder has any errors ---------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2079 URL: https://jira.jboss.org/jira/browse/JBRULES-2079 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.0.CR1 Reporter: Geoffrey De Smet Assignee: Mark Proctor Priority: Minor Fix For: 5.1.0.M1 After you 've build your package with packageBuilder, you've either called the hasErrors() method and done something about it or you didn't check the hasErrors() method because you didn't know (or want to know) it existed and you expect it to throw an exception because hasErrors() returns true. The principle of least surpise. You don't expect that it continues like everything is cool (while it's not) and crashes the moment you fire your first rules. The exception should be a runtime exception and the message should at least mention the first of the errors. The exception should probably contain a list of all errors of course too as a property.

[JBoss JIRA] Created: (JBRULES-2253) ClassNotFound when ASM optimizer kicks in in MVEL consequence

by Michael Neale (JIRA)

ClassNotFound when ASM optimizer kicks in in MVEL consequence ------------------------------------------------------------- Key: JBRULES-2253 URL: https://jira.jboss.org/jira/browse/JBRULES-2253 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Reporter: Michael Neale Assignee: Michael Neale Priority: Critical Fix For: 5.1.0.M1 (ok if the subject is really confusing, perhaps this bug isn't for you). In chasing down JBRULES-2234 I found this. Instructions (apologies for relying on Guvnor to reproduce): To reproduce is not easy, but here are some instructions: * Run latest Guvnor (if you are able to, if not, then the rest is moot !). * Import the attached repo (unzip it first). * browse to KnowledgeBases/org/acme/insurance/pricing/ - press "build package" * shut it down, restart (flushes caches etc...) Then: * browse to KnowledgeBases/org/acme/insurance/pricing/Test Scenarios * open PolicyQuotePackageTest * run it: Now you should see an exception like this: Caused by: java.lang.NoClassDefFoundError: org/acme/insurance/Policy at ASMAccessorImpl_62408281250565694450.setValue(Unknown Source) at org.mvel2.optimizers.dynamic.DynamicSetAccessor.setValue(DynamicSetAccessor.java:74) at org.mvel2.compiler.CompiledAccExpression.setValue(CompiledAccExpression.java:47) at org.mvel2.MVEL.executeSetExpression(MVEL.java:962) at org.mvel2.ast.WithNode$ParmValuePair.eval(WithNode.java:242) at org.mvel2.ast.WithNode.getReducedValueAccelerated(WithNode.java:67) at org.mvel2.ast.InterceptorWrapper.getReducedValueAccelerated(InterceptorWrapper.java:38) at org.mvel2.MVELRuntime.execute(MVELRuntime.java:85) at org.mvel2.compiler.CompiledExpression.getValue(CompiledExpression.java:104) at org.mvel2.MVEL.executeExpression(MVEL.java:995) at org.drools.base.mvel.MVELConsequence.evaluate(MVELConsequence.java:91) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:966) This is due to it loading a previously serialized version of the KB. If it was to run off a freshly compiled one, its all fine. Also, if I tell MVEL to NOT use ASM optimizer, it works fine (using reflection). So clearly the stuff is available to the classpath in the right places... its only to do with ASM in mvel post deserialization. (and for that to happen, MVEL has to execute the compiled expression enough to kick in the JIT). MVELCompilationUnit in drools is worth examining too... still not sure where the problem lies. -- 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-2179) better integration of ruleflow and AgendaFilter

by Michal Bali (JIRA)

better integration of ruleflow and AgendaFilter ----------------------------------------------- Key: JBRULES-2179 URL: https://jira.jboss.org/jira/browse/JBRULES-2179 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-core (expert) Affects Versions: 5.0.1.FINAL Reporter: Michal Bali Assignee: Mark Proctor Fix For: 5.1.0.M1 Attachments: agendaFilterWithRuleflow.zip Hi, I am creating this issue so that it won't be lost. See this post for more information: http://lists.jboss.org/pipermail/rules-users/2009-May/009110.html My original email with one reply message is pasted below: -------------------------------------------------------------- If a rule is not allowed to fire by an AgendaFilter the whole ruleflow stops. I've created a small test case (attached). It contains: - one DRL file with one dummy rule that is in some ruleflow-group. - one RF file with three nodes ('start', 'ruleflow group' and 'end') - a program that starts the process, and calls fireAllRules with custom agenda filter. Once the program is executed the ruleflow will stop inside the ruleflow-group. If I remove the agenda filter it works as expected (the ruleflow finishes). Tested with Drools 5.0.1. Best regards, Michal ---------------------------------------- Final reply from Mark: It seems like a reasonable request, that if all the rules have been cancelled, fired or filtered that the ruleflow-group should be de-activated so the flow can continue. We'll look into it for 5.1. --------------------------------------- Thanking you in advance, Michal -- 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-2243) Add support to source code assets to reference each other

by Edson Tirelli (JIRA)

Add support to source code assets to reference each other --------------------------------------------------------- Key: JBRULES-2243 URL: https://jira.jboss.org/jira/browse/JBRULES-2243 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-api, drools-compiler, drools-core, drools-eclipse Affects Versions: 5.0.1.FINAL, 5.0.0.FINAL Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 5.1.0.M1 One asset defined in one DRL should be usable from other DRLs. So we need a way to import them from one file into another, in a similar way as #includes works in C++ or "import" in java, etc. So, if I declare a type in DRL1.drl: declare XYZ ... end I can then use it in rules in DRL2.drl: uses "DRL1.drl" rule "ABC" when XYZ(...) then end Same for any other assets like functions. This feature will require proper dependency management to avoid circular dependencies, classloader issues, etc. Also, the IDE will require update to be able to properly reflect these situations without raising false errors. -- 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
