I would appreciate anyone interested in objects-as-methods on Cog pounding on the latest Cog VMs (http://www.mirandabanda.org/files/Cog/VM/VM.r2313/) as this involved substantial changes to method lookup/inline cacheing machinery and there could easily be bugs. The tests run, but they're insubstantial compared e.g. to a full coverage test. best Eliot On Sat, Sep 25, 2010 at 9:20 PM, < squeak-dev-noreply(a)lists.squeakfoundation.org> wrote: > > Eliot Miranda uploaded a new version of VMMaker to project VM Maker: > http://www.squeaksource.com/VMMaker/VMMaker-oscog.33.mcz > > ==================== Summary ==================== > > Name: VMMaker-oscog.33 > Author: eem > Time: 25 September 2010, 7:13:51 am > UUID: 733b7c50-b973-4ca0-9831-5c84d09032bf > Ancestors: VMMaker-oscog.32 > > OSCogVM: > Support object-as-method: > Eagerly evaluate the interpreter version of a primitive > to ease the object-as-method implementation and to > improve interpreter performance. > Refuse to enter anything that isn't a CompiledMethod > into the method-lookup cache to avoid open PICs having > to check for valid compiled methods. > Have various places check for isOopCOmpiledMethod: > rather than isCompiledMethod: to allow SmallIntegers to > be used as methods. > Interpreter: > Have various places check for isOopCOmpiledMethod: > rather than isCompiledMethod: to allow SmallIntegers to > be used as methods. > Slang: > support super sends by expanding them at translation > time.

[Pharo-project] MuTalk: Mutation Testing for Pharo Smalltalk
by Gabriel Brunstein Sept. 26, 2010

Sept. 26, 2010

Hi! I just want to let you know that MuTalk is available for Pharo-Dev versions 1.0 and 1.1 you can load it with monticello from http://www.squeaksource.com/MutationTesting MutationTesting-NicolasChillo.101 for loading last version in Pharo 1.1 (thanks to Francisco Ortiz PeÃ±aloza) MutationTesting-GabrielBrunstein.97 for loading last verion in Pharo 1.0 More info here: http://code.google.com/p/mutalk/ We developed it with Nicolas Chillo for our career thesis but we will continue working on it. Basically, Mutation Testing is a technique for measuring and improving tests quality. All suggestions are welcome. Bests, Gabriel PS: it doesn't work with CogVM but I think that this problem will be solved with Pharo 1.2 (we must adapt it to work there).

[Pharo-project] #copy and friends
by Schwab,Wilhelm K Sept. 26, 2010

Sept. 26, 2010

copy "Answer another instance just like the receiver. Subclasses typically override postCopy; they typically do not override shallowCopy. Copy is a template method in the sense of Design Patterns. So do not override it. Override shallowCopy instead. Pay attention that normally you should call postCopy of your superclass too." ^self shallowCopy postCopy shallowCopy "Answer a copy of the receiver which shares the receiver's instance variables. It should never be overridden. I'm invoked from the copy template method. Subclasses that need to specialize the copy should specialize the postCopy hook method." The references to #postCopy are probably valid, but the comments above can't both be correct. Right?? Bill

[Pharo-project] Implement Keyboard focus on a custom morph when have rounded corners
by nullPointer Sept. 25, 2010

Sept. 25, 2010

IÂ´m developing new widgets, integrateds in Polymorph. But when I try implement the keyboard focus appearance fails when the widget have rounded corners: http://forum.world.st/file/n2713899/RoundedCorner.png I imagine something miss, but I donÂ´t know what. I implement the keyboard focus with drawSubmorphsOn: aCanvas super drawSubmorphsOn: aCanvas. self hasKeyboardFocus ifTrue: [self drawKeyboardFocusOn: aCanvas]. Many thanks for the help :)) -- View this message in context: http://forum.world.st/Implement-Keyboard-focus-on-a-custom-morph-when-have-… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] Webpage for research paper about Pharo?
by StÃ©phane Ducasse Sept. 25, 2010

Sept. 25, 2010

guys all my papers are using Smalltalk (visualworks, squeak mainly so far) as a research vehicule. You can use them to do marketing around smalltalk because there are good papers in prestigious venues. Please do not have the time. Now pharo has the right to mention the papers using pharo on the pharo web site. Stef On Sep 25, 2010, at 12:20 AM, Sean P.

[Pharo-project] systemNavigation cleaning
by StÃ©phane Ducasse Sept. 25, 2010

Sept. 25, 2010

Hi all I'm cleaning SystemNavigation (no comment). Now I really SystemNavigation to be able to navigate a given environment (instance of SystemDictionary). Therefore I introduced an analyzedEnvironment and I will funnel most methods to use it. Now some queries are doing memory scanning (allBehaviorDo:) so I would like to use the following semantics for the method names all* will refer to methods that are not respecting the analyzedEnvironment but could scan the complete memory and I would like to introduce their pendant to convey the fact that they only take as input a given environment. Example allClasses vs classes This would allow us to have in place a nice infrastructure to load and analyse code in a separate environment and do atomica loading. This was done like that in VW30. What do you think. Stef

The problem is that I load the package Glorp and just after loading, I do a "changes" in the MC Browser and I see a lot of classes with a lot of changes and all of them like "revison changed".

I do not know. I would like to know whether the change propagates. can you do the following: - load the package - modify one method - save it - reload it in another image and you get them all dirty? In which image? do you see changes related to methodReference or timestamp? I know that the SUnit code niall sent us does not contain all the source code and that the binary is different from the source code. we should investigate that.

[Pharo-project] NativeBoost callbacks: double return values?
by Schwab,Wilhelm K Sept. 25, 2010

Sept. 25, 2010

Sig, Something that I would very much like to go on not really understanding<g> is that complexity of returning a double, and its further impact on callbacks. Aside from the usual myriad uses, my biggest interest in callbacks is for numerical analysis where double return values are very common. Is that something that you can make work by near magic? I don't really care if they require special handling, but it would be very nice if they are at least not very difficult to set up. Bill
