Analyzing Fuel Problem

Administrator

I had an object graph that was pulling in all sorts of unrelated classes when serialized with Fuel. I was trying to find the offending object, and came up with the following:
```
(FLAnalyzer newDefault analysisFor: root) clusterization globalsBucket
```

This worked, but I was wondering if that's "the right way" to do it...

Thanks.

Cheers,
Sean

Re: Analyzing Fuel Problem

Hi Sean,

Sorry for the delay on the answer. Yes, that's a good spot. Another thing I usually do is to put a halt in FLSerialization >> run. Just after #analysisStep for example, and then inspect the local variables.

Also, if you want to understand WHY an object is getting in, then you can also halt in #trace and #privateTrace: from FLAnalysis. That way you monitor which objects gets pushed into the analysis stack. You can do something like

self haltIf: [ anObject whateverConditionToHaltOnDesiredObject = true ].

Finally, there are more tools for debugging this kind of issue, but I don't know their state. You can read more about them here [1].

Best regards,
