Hi guys, are there any plans to integrate this in Pharo? As I want to do some experiments with Magma I am specially interested in Pharo-1.1 for it. Regards, Andreas

Yes, i will put changesets into pharo issue tracker, to integrate it with Pharo as well.

I am also uploaded a slice of system changes with new classes & rest

of stuff into inbox:

CollectionsTests-Igor.Stasenko.169

Collections-Igor.Stasenko.370

Kernel-Igor.Stasenko.478

System-Igor.Stasenko.358

note, that despite of these changes, system are still using old

WeakRegistry instance,

and obviously 'WeakRegistry default' needs to be modified to be

replaced with new functionality.

These inbox changes are out of date with respect to the trunk, so

would need to be merged with care.

Yeah, i did not updated the image before applying changesets.

But aside from that, is there

any reason that your changes should *not* be moved into trunk now?

If no objections, then we should include them now.

There are a couple of doits, which should be invoked after loading changes:

WeakArray restartFinalizationProcess

and of couse

Smalltalk recreateSpecialObjectsArray

Btw, i found that in image i was using,

Smalltalk specialObjectsArray size

was 50

while in #recreateSpecialObjectsArray method there was already 55 entries

(and with weak finalization it should be 56).

This should already be updated in trunk:

Name: System-dtl.333 Author: dtl Time: 25 May 2010, 9:00:22.752 pm Ancestors: System-spd.332 Update SmalltalkImage>>recreateSpecialObjectsArray for support of Alien and improved finalization (Mantis 7473). Corresponding VM support is in SqS/VMMaker-dtl.175.

So after a #recreateSpecialObjectsArray the size is 56, and the last slot is used for WeakFinalizer if present in the image.

I think that everything is ready for your WeakFinalizer updates. Unless there are any other issues, please just go ahead and commit them to trunk.

:)

I understand that the VM changes are not yet available in the

official VMs, but this should be corrected the next time that new

VMs are distributed.

Dave

Thanks, David.
