Re: [Pharo-project] Kernel

by Pavel Krivanek

Hi, with some ugly hacks i tried to run InterpreterSimulator, I hope it will help you. Try this: Gofer new squeaksource: 'VMMaker'; package: 'VMMaker'; load. (skip warnings) Load patches. Regenerate image HazelTracer2 writeImage: 'hazel.image'. Open Transcript and run the simulator: (InterpreterSimulator new openOn: 'hazel.image') test for freshProcess with the code 4 factorial. [true] whileTrue: [Beeper primitiveBeep]. the is the result: 16r00022330 BlockClosure>>#newProcess 16r0023F7B0 HazelMissingVariable>>#doesNotUnderstand: 16r0023F80C Integer>>#factorial 16r0023F868 Integer>>#factorial 16r0023F8C4 Integer>>#factorial 16r0023F920 Integer>>#factorial 16r0023F97C Integer>>#factorial 16r0023F920 Integer>>#factorial 16r0023F8C4 Integer>>#factorial 16r0023F868 Integer>>#factorial 16r0023F80C Integer>>#factorial 16r0023F7B0 HazelMissingVariable>>#doesNotUnderstand:BEEP BEEP BEEP BEEP ... This shows how much we need working InterpreterSimulator for current images :-) It works quite long for Pharo-Kernel too and on Pharo-Core it interprets a few methods as well.

Re: [Pharo-project] about morphicSoundEventtcbkss0

by Adrian Lienhard

I can't figure out what these methods have been used for exactly (probably for some conversion, there are more such methods with weird names like layoutMorphbosfcepcbbochvimol0). They have no senders, and they have been in the image since at least 1998 (I checked in a 3.2 image). I don't think anybody will miss them ;) Cheers, Adrian On Mar 4, 2011, at 21:22 , stephane ducasse wrote: > Hi guys > > does anybody have an idea why SmartRefStream would need to refer to MorphicUnknownEvent? > > morphicSoundEventtcbkss0 > ^ MorphicUnknownEvent > > Stef (the Ultimate Random Refactorer)
