[Pharo-project] Combining Regular Monticello with Github/FileTree
by Sven Van Caekenberghe Dec. 2, 2012

Dec. 2, 2012

Hi, Before I get too frustrated trying, a quick question: is it possible to combine regular monticello with github/filetree ? I have STON both in ss3 as on github, but it seems I cannot compare my in-image ss3 version with a filetree/github repository on disk: it reports everything as changed (maybe due to meta data differences, I don't know). How do I know the difference between the ss3 version and the filetree version ? I guess I could just save the filetree version and let git decide ? But maybe, then everything will be different as well ? Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] STON Update
by Sven Van Caekenberghe Dec. 1, 2012

Dec. 1, 2012

Hi, Based on feedback by Norbert Hartl, Stuart Herring and Dale Hendrichs (thank you) I improved the current STON version a bit. http://ss3.gemstone.com/ss/STON https://github.com/svenvc/ston Changelog: A nasty cycle bug was fixed Performance was improved, especially for large structures. Some implementation changes (recursion done using a stack, stonProcessSubObjects: optimized using stonContainsSubObjects) I did some stress/performance testing/tuning. Using STONTestMap classTreeExtended. to generate a structure mimicing the class hierarchy, with objects for all classes, about 7000 in my image and all methods, about 64000 in my image, with super/subclass and method owner links to create cycles. This results in a 7 Mb .ston file. The normal code, serializes this in 28 seconds and materializes it in 11.5 seconds. The 'fast' versions (using ZnBuffered[Write|Read]Streams and Fuel Large Datastructures) does it in 1.1 and 3.8 seconds respectively. New users are always welcome.

[Pharo-project] CogVM crash code
by Jon Anderson Dec. 1, 2012

Dec. 1, 2012

Hi all, I don't post to lists often, but I thought some of you might be interested in these few lines of code that crash the CogVM on both Linux and Windows. File-in the Smalltalk code below, then evaluate [nil crashCogVM]. The code uses [1-1] but it could use [1+1] or [56+98]. I put the code on nil, but that is not important either. I think the important thing is that the primitive (+ or -) is evaluated but the result is not assigned into any variable. Also important is that the code is put into a loop that I assume has been JIT optimized. The image I used is Pharo 1.4 one-click with latest update #14459. This code does not crash StackVM. Have fun! - Jon. !UndefinedObject methodsFor: 'crash' stamp: 'JonKAnderson 11/29/2012 17:26'! crashCogVM " Evaluate [ nil crashCogVM ]" | i | i := 20. 1 to: i do: [:d | 1-1 ] ! !

[Pharo-project] About ArrayedCollection and at:/put:
by Igor Stasenko Dec. 1, 2012

Dec. 1, 2012

It says: "I am an abstract collection of elements with a fixed range of integers (from 1 to n>=0) as external keys." now that leaves me clueless, why then it does not defines (introduces) a protocol: #at: and #at:put: at least as an abstract one , i.e. subclassResponsibility is it because they are already in Object protocol? And because subclasses (like Array) using default #at: implementation? I don't know, but i think Object should not have #at:/#at:put: protocol.. because: - it applicable only to variable subclasses - many classes have own implementation of it - the behavior behind this is to access a variable fields . while other classes use this protocol for higher abstractions (like dictionaries) so, to my thinking, Object should not define this protocol.. for this purpose we having #basicAt:/put: methods. btw, just an idea to clarify things even more, we could rename them to variableAt: [put:] (or any other name which properly tells that method provides an access to variable fields of object). -- Best regards, Igor Stasenko.

[Pharo-project] Changes in announcements
by Ezequiel Lamonica Dec. 1, 2012

Dec. 1, 2012

Hi, I was reviewing with Esteban about the lack of some announcements in the system and some bugs in other ones. I've been working on that for this week. This is the list: -MethodRename -Snapshot -Session (i don't know if this is necessary) -VariableAdded (one for every kind) -VariableRemoved (one for every kind) -Protocols (add/modif/remove/rename) -TraitComposition - When a package is created, the announcement is not released This only happens when a class is created with that category. -When I modify a class and also I change its category, then only class recategorized announcement is sent -Package removed is not sent

[Pharo-project] Trying Athens
by Casimiro de Almeida Barreto Nov. 30, 2012

Nov. 30, 2012

I've had strange problem with Pharo 2.0: it times out at Gofer. For instance: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSeaside30'; load. Will spend the 30secs timeout & then give-me a debugger window complaining that could not connect. But network is OK and Pharo 1.4 does not have this problem. Besides, Pharo 2.0 updates OK (so, again, there's no network problem). CdAB

[Pharo-project] Indent code
by Torsten Bergmann Nov. 30, 2012

Nov. 30, 2012

When I select a few lines of text in Pharo 2.0 code editor and hit TAB it is not indented as in other IDE's. Instead it is deleted similar to when one hits space key. Usually TAB in IDE code editors is used to indent a selected block of text and SHIFT+TAB is used for the reverse (outdent). Is this a bug or just handled differently? Thx T.
