[Pharo-project] WTF? why this can happen?
by Esteban Lorenzano May 21, 2012

May 21, 2012

Hi, "expanded" is a Set with just one element. executing (somewhere inside pier): expanded removeAll: expanded copy throws NotFound digging a bit, I found that the #scanFor: message answers 5 and real position of object in array is 1 (array size is 5, btw). in: scanFor: anObject "Scan the key array for the first slot containing either a nil (indicating an empty slot) or an element that matches anObject. Answer the index of that slot or raise an error if no slot is found. This method will be overridden in various subclasses that have different interpretations for matching elements." | index start | index := start := anObject hash \\ array size + 1. [ | element | ((element := array at: index) == nil or: [ element enclosedSetElement = anObject ]) ifTrue: [ ^index ]. (index := index \\ array size + 1) = start ] whileFalse. self errorNoFreeSpace this line: index := start := anObject hash \\ array size + 1. is answering 5... so method ends on first ifTrue: but... what the hell???????? any idea? thanks, Esteban

[Pharo-project] Browsing long methods
by Guillermo Polito May 21, 2012

May 21, 2012

Browsing a long method (lets say, of ~270KB of sourcecode) just hangs the image. Interrupting doesn't even give me control over my image again. It does no open a debugger, but info is printed in stdout, so I assume that my UIProcess died, but the event fetcher is still alive... One of the processes that get interrupted prints: SmallIdentityDictionary(SmallDictionary)>>at:ifAbsent: MorphExtension>>valueOfProperty:ifAbsent: MorphExtension>>valueOfProperty: ScrollBar(Morph)>>valueOfProperty: ScrollBar(Morph)>>theme ScrollBar>>normalThumbFillStyle ScrollBar>>adoptGradientColor: ScrollBar>>sliderColor: ScrollBar>>adoptPaneColor: PluggableMultiColumnListMorph(Morph)>>adoptPaneColor: in Block: [:m | m adoptPaneColor: paneColor] So I just changed #adoptPaneColor: in ScrollBar to do nothing, and I am able to interrupt again. So it makes me think here it is where the UIProcess gets killed... Now, for the browser stuff, it seems that TextComposer>>#composeAllLines never finishes. I'm still investigating, but any clue is helpful :). Guille

[Pharo-project] About process startups
by Guillermo Polito May 21, 2012

May 21, 2012

I'm playing with the process initialization for the bootstrap, and some things come to my mind. There are some classes that startup processes on the class side initialize, like WeakArray -> Finalization process Delay -> Timer event loop What it is not clear to me is if those processes should be installed when the class is initialized, or when it is startupped for the first time. Also, I can't stop thinking that the processes in the image are all spread and not clear. If I want to know where the processes are defined, it's kind of a mess. Is having specialized objects for our processes undesired by some reason I can't see? I'd like to have objects like MorphicUIProcess FinalizationProcess TimeEventProcess ... and so on Guille

[Pharo-project] Inspecting keys in Dictionaries
by Davide Varvello May 20, 2012

May 20, 2012

Hi, I'd like to inspect keys of a Dictionary but if I open an inspector on the dictionary and inspect a key, the inspector shows its value, instead I'd like it shows the key object. Is there an easy way to do it? Cheers Davide -- View this message in context: http://forum.world.st/Inspecting-keys-in-Dictionaries-tp4630944.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
