Re: [Pharo-project] out of memory - cog on windows

by Tudor Girba

Hi, I am back with some more input on the matter. We played with it, and found that basically any image that goes beyond something like 200MB limit (or maybe it's the number of objects), will not open on Windows. I would need some help on this. Has nobody else hit this wall, or is it that I am doing something wrong? One scenario that we used to reproduce the problem looks like this: 1. Take a Moose image: http://hudson.moosetechnology.org/job/moose-latest-dev/lastSuccessfulBuild/… 2. Run: 1 to: 3 do: [ :i | MooseScripts createModelForConfigurationOfMoose ] This will basically create some 850000 objects and will get the image to some 400+MB 3. Save and quit the image 4. Reopen it A ready-made image with the result of this can be found here: http://dl.dropbox.com/u/18323746/Tmp/moose-case-study-windows-problem.zip This works well on Mac, but on Windows when you reopen the image, you get the out of memory message.

Thanks for your excellent point. I think it is somehow related to that. Please look the attached screenshot. All the windows for exploring objects are from the incorrect CM, and the windows showing the code is from the correct CM. Its weird because it seems those incorrect CM are pointed from closures inside the correct CM? what is even worst, is that even after removing those correct CM, and doing a GC etc...they still don't disappear. > Nicolas > > > -- > > Best regards, > > Igor Stasenko AKA sig. > > > > > > -- Mariano http://marianopeck.wordpress.com

Hi Peck, Instead of running the Gofer script, can I download the each package and load it in my Pharo.

I see now both both classes used the same Trait, thus the apparent duplication of methods. Is there a way to see just those methods of a class which are not part of a Trait that's being used? I tried deleting the portion of the class definition "uses: TEasilyThemed", but it reappears when saving the class. -- View this message in context: http://forum.world.st/Parent-of-ExampleBuilderMorph-tp3510422p3510990.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
