Hello,

going further with the instrumentation to get debugging for non trivial language I stumble upon the following errors: "Produced region is inconsistent"

I understand that the trace annotations are not in line with what is expected but I fail to understand how this happens.

Let me be more specific, with the following dsl code everything is fine:

InExpression (for all @EXPRESSION.Value as value) {
    if (value.valueString in ('foo', 'bar')) {
          // save value
    }
}

Now here is my problem:
1) I carefully checked my stacktrace and no of the method are missing the @Traced
2) What happens exactly, I see the result but I fail to understand the process
3) How can I unit test this. It is pretty tedious to have to start eclipse.

Many thanks for your help




However uncommenting the save valuer statement in the if yield to 
8337014 [Worker-21] ERROR org.eclipse.xtext.generator.trace.internal.AbstractTraceForURIProvider  - Produced region is inconsistent with parent, this: TraceRegion [myOffset=699, myLength=49] associations={
  LocationData [TextRegionWithLineInformation [153:22][lineNumber=5, endLineNumber=7]][path=Conditions-1.0.0.wkfs]
},
...

What is interesting is that in the first case the region are clearly whereas not in the second case because the code of the save (createOrUpdate) is outside of the ]03,02]

Hmmmm your questions getting more and more advanced and
I don't have the time to create an example to reproduce your stufff.

Regarding unit tests:
Can you post a stacktrace of where the error happens

Hello Cristian,

thanks for looking at it. Here is some more information and the full strack trace. (just a note to say that it works for toy examples)

	@Traced def dispatch  generate(IfStatement statement, GeneratorContext context) {
		'''
			if («statement.condition.generate(context)») {
			    «statement.then.generate( context)»        //This calls the block statement code below, if remove everything goes fine
			} «IF statement.^else!==null»else {
						    «statement.^else.generate(context)»
			}«ENDIF»
		'''
	}



	@Traced def dispatch  generate(BlockStatement statement, GeneratorContext context) {
		'''
			«FOR s : statement.statements»
				int i = 0;                //<--- This is not the real code, normally at this we can treat any statement but just putting a hardcoded statement reproduces the problem
			«ENDFOR»
		'''
	}

The exception already shows tostring of the regions so you should see the inconsistency there

You should be able to combine GeneratorNodeProcessor and the traceregion serializer in a unit test

And as I tried to hint. A simple reproduce example with just the problem would help me
(And possible you) so having an example with and if else and a hard coded for only would help
And maybe Understand if this is a bug or something else.

The interesting point is that this is a offf by one issue so
Are you on windows or a Unix like os?

What happens if you do the if else and the for all in one line including the ''''''

Hello Christian,

thanks for the unit test. I got the hint don't worry I will try to build a simple and reproducible unit test.
As for the other question, I am on windows. By the way, how did you detect the off by one with the trace?

[myOffset=581, myLength=132]
[myOffset=699, myLength=15]

581+132 = 713
699 + 15 = 714

maybe similar issue to https://github.com/eclipse/xtext-core/issues/483 ? which xtext version do you use?

Thanks for the explanation, using 2.12

ok I can confirm that the problems comes from the for loop, removing and externalizing it solves the problem for that portion of code.
However I can reproduce it with a
«IF statement.^else!==null»else {
    «statement.^else.generate(context)»
}«ENDIF»


So I guess the problem is more general.
Will move to 2.13 that may take some time.

btw could not reproduce with

Model:
	ifStatement=IfStatement;

IfStatement:
	'if' condition=BooleanLiteral
	then=BlockStatement
	('else'
	else=BlockStatement)?;

BooleanLiteral:
	value?="true" | {BooleanLiteral} "false";

BlockStatement:
	{BlockStatement} "{"
	statements+=Literal*
	"}";

Literal:
	value=ID;



class MyDslGenerator extends AbstractGenerator {
	
	@TracedAccessors(MyDslFactory)
	static class MyDslTraceExtension {
		
	}
	
	@Inject extension MyDslTraceExtension

	override void doGenerate(Resource resource, IFileSystemAccess2 fsa, IGeneratorContext context) {
		val model = resource.contents.head as Model
		
		fsa.generateTracedFile("test.txt", model,'''
			«model.ifStatement.generate(context)»
		''')
	}
	
	@Traced def dispatch  generate(IfStatement statement, IGeneratorContext context) {
		'''
			if («statement.condition.generate(context)») {
			    «statement.then.generate( context)»        //This calls the block statement code below, if remove everything goes fine
			} «IF statement.^else!==null»else {
						    «statement.^else.generate(context)»
			}«ENDIF»
		'''
	}
	
	@Traced def dispatch  generate(BlockStatement statement, IGeneratorContext context) {
		'''
			«FOR s : statement.statements»
				int i = 0;                //<--- This is not the real code, normally at this we can treat any statement but just putting a hardcoded statement reproduces the problem
			«ENDFOR»
		'''
	}
	
	@Traced def dispatch  generate(BooleanLiteral statement, IGeneratorContext context) {
		'''«statement._value»'''
	}
	
}	



if true
{
	x
	y
	z
} else {
	a
	b
	c

Still have the problem with 2.13, and according to your test, it is something peculiar in my setting. Will try to build a minimum viable unit test to reproduce

Hello,

still trying to create the unit test regarding the serialisation
		val CompositeGeneratorNode rootNote = tracingSugar.trace(expr, expr.generateBody(context))
		val GeneratorNodeProcessor.Result result = processor.process(rootNote)

		val OutputStream outputStream = new BufferedOutputStream(new FileOutputStream("trace.txt"));
		serializer.writeTraceRegionTo(result.traceRegion, outputStream)
		outputStream.close


The generated file is not readable and the process does not generate an exception (with the production code)
Am I missing something?

shouldnt the call to the serializer already fail?
simply calling the whole doGenerate is not an option?

and the file extension should be ._trace
and it should already fail there

and againthe question: my example works on your machine?

No actually the simple example does not work and also yields an exception when I open the ._trace. Interestingly enough I do not get the exception during code generation.

yes but you should be able to have a look at the trace file tree at least. the problems is that the uris to source and target file will be invalid in your test i think.
can you share anything that lets me easly reproduce. even with calling the generator?

Sorry false alarm. Actually the problem in the small example was comming from the fact that I had two dsl files and the target test.txt is hardcoded. When I put a random file name. It works without exception

Indeed, and now I am completly confused, I cannot reproduce the error at all (included with my code). I am ... lost. Will redo it step by step...
