[Pharo-project] Class>>asRingDescription
by Fernando Olivero Sept. 15, 2011

Sept. 15, 2011

Veronica, i've started to adopt Ring in Gaucho. Very nice work, excellent tests also! A question, why does the following is true? Collection asRingDefinition methods isEmpty = true If you look at the following method, they should be added here right?, on the ring definition creation. Class>>asRingDefinition | ring | ring := (RGFactory current createClassNamed: self name) category: self category; superclassName: self superclass name; traitCompositionSource: self traitCompositionString; addInstanceVariables: self instVarNames; addClassVariables: self classVarNames; addPoolDictionaries: self poolDictionaryNames; comment: self organization classComment; stamp: self organization commentStamp; definitionSource: self definition; withMetaclass. ring theMetaClass traitCompositionSource: self theMetaClass traitCompositionString; definitionSource: self theMetaClass definition; addInstanceVariables: self theMetaClass instVarNames. ^ring I'm using the latest Pharo1.4 from Jenkins.

[Pharo-project] What is an abstract method?
by Alexandre Bergel Sept. 15, 2011

Sept. 15, 2011

Hi! Apparently, the following method is abstract: ArrayedCollection>>add: newObject self shouldNotImplement If I evaluate: (ArrayedCollection>>#add:) isAbstract => true This is not quite right. A method that is cancelled is not abstract. I propose to change CompiledMethod>>abstractMarkers ^ #(subclassResponsibility shouldNotImplement) into CompiledMethod>>abstractMarker ^ #shouldNotImplement Does it make sense?

[Pharo-project] Fuel or image segments (project files)
by Dimitry Golubovsky Sept. 15, 2011

Sept. 15, 2011

Hi, The application I am working on (which currently runs under Squeak VM on Android) will be migrated to Pharo. The current version heavily relies upon use of image segments (projects) which provides a simple (though slow) way to save/restore the application data not touching the image (the Squeak port is unable to save images anyway, Cog can do this, but I'd rater not touch the image) with versioning. Are image segments supported in Pharo Core same way? I saw a message about stopping the support of image segments in future versions of Pharo in favor of Fuel. What is current status of Fuel development? Is it usable? Thanks. -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] State of art for testing tools in Pharo?
by Simon Denier Sept. 15, 2011

Sept. 15, 2011

I would like to know what's the state of the art when it comes to tests in Pharo. What are the habits? The best practices? Is there any ongoing development? I stumble upon that this morning (through twitter) http://www.lshift.net/blog/2011/09/13/checking-squeak-quickly Especially, I am interested in the following topics: - any framework to perform BDD? What's the status of SSpec? I also saw that Sean was starting to play with Cucumber, I would be very interested to see that - developing a Seaside app in TDD/BDD mode? Is there a tutorial out there about that? I stumbled upon Seaside Testing, which looks like an interesting layer http://www.shaffer-consulting.com/david/Seaside/TestingComponents/TestingCo… -- Simon Denier

[Pharo-project] Debugger bug fix 1
by Michael Roberts Sept. 14, 2011

Sept. 14, 2011

So I found the bug with the first assignment. It is caused by a difference between squeak and Pharo in SortedCollection. (on my phone so will be brief) In Pharo the debugger map collection gets sorted and asked for an index for a given pc. It is supposed to answer 1 because there is no match and it is expected to be the first index for insertion. However when the asSortedCollection gets done the internal start index of the collection is 2. This manifests the bug. 2 is answered as the insertion position but this is a value internal to the collection. Squeak does not have this bug because it forces a reset of the start index to 1. Hope that makes sense. I don't know what the correct fix is. We copy the reset:1 type code to force the collection to have start from 1 property. We check semantics of index for insertion. Is it the position of the element of index relative to pointers? Or we change the debugger to calculate the offset (but this feels wrong) So this is an opportunity for some test cases and fixes around sorted collection if we know what the correct semantics are. This leak of '2' out of the collection is only wrong if 2 is a valid state. If that makes sense... Cheers Mike
