I can imagine multiple problems: 1- some packages override some methods of the core which are reseted on update. That could be fixed but would require some work from package maintainers 2- some updates require that no window are displayed (like Polymorph updates) There are probably others -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."

This is excellent news. I loaded a complete set of development tools into the latest Pharo and it seems to work perfectly. Nothing missing.

Yes, it loads without problems and it does not have overrides.

Re: [Pharo-project] GC limitations?

That said, some debugging lead me to a situation I really do not enjoy: objects that I think should be gc'd are happily living in my image. I _think_ I have gagged workspace variables (they truly are more trouble than they are worth). Dolphin sometimes has "zombie" views that can lurk in a broken/invisible state but still hold onto other objects. Is there anything like that here? I know about the various #become: tricks, and do not like to resort to them; I would like to understand what is holding onto the would-be garbage. > > Can the Squeak/Pharo gc collect objects with cyclic references?

From the class comment: I can search for reasons why a certain object isn't garbage collected. I'm a quick port of a VisualWorks program written by Hans-Martin Mosner. Call me as shown below. I'll search for a path from a global variable to the given object, presenting it in a small morphic UI.
