Hi
I have a quite fun bug. I load some code and suddenly the packageOrganizer is wiped out and contains worng information. I checked checked checked no success so far and I would love to have something to say notify me when any change happen to the dictionary of packageOrganizer.
I has similar thoughts about tracking the object's changes. It could possibly done by replacing a reference to an object by proxy, which intercepts all messages sent to it and then, sending the same message to wrapped object, and after that, compares a object's contents with its hollow copy (which made beforehead). Then , if change is detected - notify a listener.
So, this is quite easy to implement.. but integrating it into a debugger is a lil bit another story :)
The proxy gives problems with identity, but indeed change tracking is solvable as in <http://scg.unibe.ch/archive/papers/Reng08aTransMemory.pdf>. I guess what Stef wants is more something like <http://scg.unibe.ch/archive/papers/Lien09aCompass.pdf>. Lukas -- Lukas Renggli www.lukas-renggli.ch
