Description

Hi.

The following usage example of using traits in pipelines does not work:



  • src/Theon.groovy :

    class Theon implements TraitOr {

        def bar() { 42 }

    }


  • src/TraitOr.groovy :

    trait TraitOr {

        def foo() { bar() }

    }


  • vars/test.groovy

    import Theon

    def foobar () {

        new Theon().bar()

    }

    //foobar() // uncomment to test invocation with standard Groovy interpreter

I get the following stracktrace (with Jenkins plugins: "Pipeline"==2.5, "Pipeline: Groovy"==2.39 and "Pipeline: Shared Groovy Libraries"=2.8), whereas it works fine in Groovy standard interpreter 2.4.8 with Java8:

Finished: FAILURE

With only basic knowledge of the "groovy-cps" implementation, I naively tried to write a minimal test case in Groovy, but the following code (inspired by AbstractGroovyCpsTest.groovy) fails to reproduce the issue I see in Jenkins :

@​Grab(group='com.cloudbees', module='groovy-cps', version='1.18')



import org.codehaus.groovy.control.CompilerConfiguration

import com.cloudbees.groovy.cps.*

import com.cloudbees.groovy.cps.impl.*



def cc = new CompilerConfiguration()

cc.addCompilationCustomizers(new CpsTransformer())

cc.scriptBaseClass = SerializableScript.class.name



String code = """

import Theon

def foobar () {

    new Theon().bar()

}

foobar()

"""

Script script = new GroovyShell(new GroovyClassLoader(this.class.classLoader), binding, cc).parse(code)

try {

    script.run()

} catch (CpsCallableInvocation inv) {

    println(inv.invoke(null, null, Continuation.HALT).run(10000).replay())

}

(I think this code fails to use a CPS-transformed version of the Theon & TraitOr classes)

What do you think: is this a "groovy-cps" issue or a "workflow-cps-plugin" issue ?

Hi.



The following usage example of using traits in pipelines does not work:


    

    	
  • src/Theon.groovy :

    

    class Theon implements TraitOr {

        def bar() { 42 }

    }
    

    • 




    

    	
  • src/TraitOr.groovy :

    

    trait TraitOr {

        def foo() { bar() }

    }

    

    •

    def foobar () {

Finished: FAILURE





With only basic knowledge of the "groovy-cps" implementation, I naively tried to write a minimal test case in Groovy, but the following code (inspired by AbstractGroovyCpsTest.groovy) fails to reproduce the issue I see in Jenkins :




@Grab(group='com.cloudbees', module='groovy-cps', version='1.18')



import org.codehaus.groovy.control.CompilerConfiguration

import com.cloudbees.groovy.cps.*

import com.cloudbees.groovy.cps.impl.*



def cc = new CompilerConfiguration()

cc.addCompilationCustomizers(new CpsTransformer())

cc.scriptBaseClass = SerializableScript.class.name



String code = """

import Theon

def foobar () {

    new Theon().bar()

}

foobar()

"""

Script script = new GroovyShell(new GroovyClassLoader(this.class.classLoader), binding, cc).parse(code)

try {

    script.run()

} catch (CpsCallableInvocation inv) {

    println(inv.invoke(null, null, Continuation.HALT).run(10000).replay())

}





(I think this code fails to use a CPS-transformed version of the Theon & TraitOr classes)



What do you think: is this a "groovy-cps" issue or a "workflow-cps-plugin" issue ?

Research direction

Reproduce the failure with src/Theon.groovy, src/TraitOr.groovy, and vars/test.groovy, then inspect the CpsTransformer.visitArrayExpression stack-trace location. Compare the pipeline behavior with the standard Groovy interpreter; done means the trait example compiles and its invocation works without the reported UnsupportedOperationException.
