Hi guys. I am since yesterday trying to find something and I cannot. So at
this point I need external eyes :)
I have this little code:
anObject := ClassWith2Var new.
sharedObject := ClassWith1Var new.
sharedObject var1: 'nose'.
anObject var1: Date today.
anObject var2: sharedObject.
serializedObjects := FuelMareaSerializer new serializeAndWriteObject:
anObject to: 'aFileName'.
anObject := nil.
sharedObject := nil.
3 timesRepeat: [Smalltalk garbageCollect].
serializedObjects inspect.
What is important here is that FuelMareaSerializer new
serializeAndWriteObject: anObject to: 'aFileName' answers a
WeakOrderedCollection with each object of the serialized graph (taking
anObject as the root)
Now, if I print the tempVar serializedObjects I see:
a WeakOrderedCollection(ClassWith1Var ClassWith2Var Date DateAndTime
Duration a ClassWith1Var a ClassWith2Var 3 August 2011
2011-08-03T00:00:00+02:00 0:02:00:00 1:00:00:00 86400 2455777 'nose' 0 7200)
WHYYYY?? why are all there if I put a nil to both, anObject and
sharedObejct. This WeakOrderedCollection should be with all nils (except
classes). Why are not being garbage collected?
If I explore, for example the tempVar sharedObejct, which is at
serializedObjects at: 6 and then I put explore pointers I ONLY see the
array of the WeakOrderedCollection pointing to it. I don't understand.
Any help is really appreaciated.
