Re: [Pharo-project] Strange behavior of Metacello in Pharo 2.0

Alexandre, Is "utterly fail" a technical term:)? Do you get a walkback? Do you get an error message?

Going to 4Gb or maybe 8Gb would be a great thing. > It is possible to have an image of at least 7GB (I have done this on my PC with 8GB real memory). Currently this requires tracing the image to a 64-bit object format with SystemTracer, and running the image on an interpreter VM compiled for the 64-bit format. I expect that this will work for Moose in a Pharo image, although performance of the garbage collector is likely to become an issue as the memory grows with lots of smaller objects, and the 64-bit interpreter VM will be significantly slower than a 32-bit Cog VM. If you want to try this with one of your images, I'll try to give you some help. I believe that Eliot has longer term plans for 64-bit object formats, VMs, and improved garbage collectors. Dave

[Pharo-project] How to filter out method extensions in Ring?

by HernÃ¡n Morales Durand

Hello all, You may help me on this one. I want to filter out method selectors which are extensions of a particular class. For example, in Pharo 1.4 the ArrayedCollection class has these selectors: ArrayedCollection selectors asSortedCollection I would want all of them except #writeOnGZIPByteStream: which is in "Compression" package. I did a try to Ring ArrayedCollection selectors asSortedCollection collect: [ : each | RGMethodDefinition class: ArrayedCollection selector: each ] with MethodReference I did : ... ( each category beginsWith: '*' ) not ... but it seems not supported in Ring? Any hints? Cheers, HernÃ¡n
