[Pharo-project] Subscript out of bounds: 1 on latest (hudson) Pharo 1.3

by Guillermo Polito

Hi! I want to load a 6 month old slice (SLICE-Issue-1907-SetWithNilTests-GuillermoPolito.2) from pharo inbox in latest 1.3(13204) from hudson using cog, and It opens a pre-debugger because of a Subscript out of bounds: 1. If I clic on it to debug, It throws me again the same error :(. It happens if there is the sources file or not. But the most strange is that if I download latest 1.3 from the bottom of the page: http://www.pharo-project.org/pharo-download It actually loads the Slice, but throws me a DNU if I dont have the sources file in the same folder: 19 May 2011 9:02:38 pm VM: unix - i686 - linux-gnu - Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.47] Image: Pharo1.3a [Latest update: #13201] UndefinedObject(Object)>>doesNotUnderstand: #keywords Receiver: nil Arguments and temporary variables: <<error during printing> Receiver's instance variables: nil CompiledMethod>>getSourceReplacingSelectorWith: Receiver: (TPrintTest>>#testPrintElementsOn "a CompiledMethod(842792960)") Arguments and temporary variables: newSelector: #testPrintElementsOn oldKeywords: nil newKeywords: nil args: nil newSelectorWithArgs: nil source: '' oldSelector: nil s: nil Receiver's instance variables: (TPrintTest>>#testPrintElementsOn "a CompiledMethod(842792960)") DictionaryTest class(Behavior)>>addTraitSelector:withMethod: Receiver: DictionaryTest Arguments and temporary variables: aSymbol: #testPrintElementsOn aCompiledMethod: (TPrintTest>>#testPrintElementsOn "a CompiledMethod(842792960)...etc... source: nil methodAndNode: nil Receiver's instance variables: superclass: CollectionRootTest methodDict: a MethodDictionary(size 192) format: 162 instanceVariables: #('emptyDict' 'nonEmptyDict' 'nonEmpty5ElementsNoDuplicates'...etc... organization: ('helpers' aValue anIndex anotherValue) ('requirement' anotherEle...etc... subclasses: {SmallDictionaryTest.

[Pharo-project] VW's ObjectRegistry similar in Pharo?

by Mariano Martinez Peck

Hi guys. We are doing graph traversal (for Fuel) and we would love a collection to be really fast and only support two simple operations: #add: and #includes: The idea is that each object we process of the graph we put it in the collection and then for each object we have to ask whether it is included or not (to avoid cycles and putting the same object more than once). VW seems to have ObjectRegistry (subclass of IdentitySet) which is more or less that. It is used by ObjectTracer, which in fact is what we want to do. And even more, Parcels uses that ;) (or an extension of that). So...I wonder, is there a special collection implementation ideal for this case? is something similar to ObjectRegistry available for pharo ? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] SIXX problem for ScaledDecimal

by Chris Cunningham

For ScaledDecimal, SIXX should definite store it as the underlying fraction. Storing it in the printed fashion does change the value of the ScaledDecimal. (1/3) asScaledDecimal: 2 gives 0.33s2 and (33/100) asScaledDecimal: 2 gives 0.33s2 yet 0.33s2 ~= ( (1/3) asScaledDecimal: 2 ) and ( (1/3) asScaledDecimal: 2 ) ~= ( (33/100) asScaledDecimal: 2 ) In other words, the ScaledDecimal is about the precise internal number and the scale to display it - which is NOT the scale that it is stored as. -Chris

[Pharo-project] problem with Dictionary and KeyNowFound

by Mariano Martinez Peck

So...it seems Pharo1.3 change Dictionary to throw KeyNotFound instead of Error. Now, my image freezes with a loop. I would appreciate some help. I couldn't really analyzed the problem. Fileine both FLPerson.st and ATest and run the test testDictionaryRehash. In such test, a the end there is a self shouldnt: [aDictionary at: newPerson1] raise: KeyNotFound. which raises the debugger pre-popup. if I try to click on the popup... -> loop/freeze. You can interrupt it and see more or less what is happening. Camillo, can you take a look? Thanks -- Mariano http://marianopeck.wordpress.com
