Re: [Pharo-project] Memory usage

I'm sure I built a vm for 64 bits a few years back, maybe not a stack one, can't remember ya http://lists.squeakfoundation.org/pipermail/vm-dev/2010-January/003732.html On Tue, Jul 31, 2012 at 11:01 AM, David T.

[Pharo-project] We cannot remove package [was] Re: How to correctly remove a package for everywhere?

by Mariano Martinez Peck

So....again this problem. Please guys, this is a stop-the-world problem. We simply cannot remove packages. In http://code.google.com/p/pharo/issues/detail?id=6493 I removed lots of packages. The packages does not seem to appear, but classes are still present. For example, FLPackageStore is from the removed package FuelPackageLoader. However, if you browse that class it exists and it is under _UnpackagedPackage we really need to fix this.

Re: [Pharo-project] Memory usage

by John McIntosh

A few years back the interpreted virtual machine was fixed to allow an image to grow to the 4 GB limit. It is unclear to me if someone regressed the software to impose a 2GB limit again, or if the 2GB number mentioned is based on how things worked10 years ago?

Please do. I do have a few things I don't know how to solve :-( But, interestingly, sometimes things which looks like bugs in this browser are really like that in the system (such as overlapping packages?).

[Pharo-project] A VM-dev blog. (Was: Re: Going meta (VM development))

by Igor Stasenko

So, i registered a blog on wordpress and sent invitation to join to following people: Esteban, Dave, Eliot, Guillermo, Camillo, Dimitry, Sean. The blog address is dailyVMotion.wordpress.com The idea behind this blog is to brag about what you do, what you did or what you plan to do.. It don't have to be too technical or too precise (as documentation does), but just hold enough information to navigate in the VM sea and stay tuned. So, people can put notes, read others notes, comment, and then (the most important aspect) return back to things after a while once they find time to deal with it, instead of digging mail archives.. Not saying, that visitors can be more aware of what happens around VM. Note, this is NOT my private blog or something. All participants will have admin rights and all can post whatever they want there, of course if it related to VM. So, if you like the idea, then join :) P.S. I am not sure that i invited all today's Cog VM developers. So, if i miss someone, please forgive me, (it was not intentional) and let me know, so i can fix this :) -- Best regards, Igor Stasenko.
