Compiler+Decompiler together have a serious 'bad case' bug
by Klaus D. Witzel 27 Jul '06

27 Jul '06

http://bugs.impara.de/view.php?id=2921 You can provoke the emergency console by having Decompiler fail with self error:'bad case' in #send:super:numargs. The following trivial, innocent looking code snippet does it in 3.8 and 3.9: | x y | x := y := 0. {'a'. 'b'. 'c'} do: [:c| (c string halt; endsWith: 'd') ifTrue: [x:= 1 + x] ifFalse: [y:= 1 + y]] Strange, why should Decompiler be involved in a halt situation, and then, why should it refuse to decompile code? /Klaus

aCompiledMethod>>#= puzzle
by Klaus D. Witzel 26 Jul '06

26 Jul '06

This is a puzzle. I will donate EUR 50 to the Squeak project ( http://www.squeak.org/Donate/ ) if you post a satisfying answer here in squeak-dev. Input: any two instances of CompiledMethod and a series of questions and answers. You can ask other / more questions, except a question like "is <this> the answer" where <this> means your guess. Q1: do the 2 methods have equivalent header? A: no Q2: do the 2 have same bytecode size? A: no Q3: do the 2 have the same literals? A: yes Q4: do the 2 send different messages? A: no Q5: do the 2 send messages to diffent temps or instVars or other? A: no Q6: given any input, do the 2 return the same result? A: yes Q7: given any input, do the 2 perform the same sequence of message sends? A: yes Q8: does the one with *more* bytecodes run faster? A: yes So the 2 differ in bytecodes and performance. Q: what's the name of the *longer*, in terms of bytecodes, method? With name it is meant, under what name is the method known in the field (in the public). A: your solution to the puzzle /Klaus

Re: [Newbies] Splitting strings
by ncellier＠ifrance.com 26 Jul '06

26 Jul '06

I see at least two alternatives: - Stream - VBRegex If you have a single separator string, then Stream already has the upToAll: method (leave stream positioned before occurence...) | testString sep subStrings inputStream | testString := 'split that string in this language'. sep := 'th'. subStrings := Array new writeStream. inputStream := testString readStream. [inputStream atEnd] whileFalse: [ subStrings nextPut: (inputStream upToAll: sep). inputStream throughAll: sep]. ^subStrings contents VBRegex is more powerfull of course (it can match several different separators at once). I let you inquire about it. Nicolas Damien Pollet: > Hi, > > is there anything like ruby's String#split in Smalltalk?
