RFC: make ctrl-shift-d debug instead of duplicate (?)
by Tobias Pape 24 Jun '15

24 Jun '15

Hi, I am still a bit puzzled that debugIt has no keyboard shortcut. I think ctrl-shift-d (viz ctrl-d for doIt) would fit. In TextEditor and ParagraphEditor, this is used for Duplicate: duplicate: aKeyboardEvent "Paste the current selection over the prior selection, if it is non-overlapping and legal. ..." I have never used it and it seems to be non-obvious. Who is with me overtaking the shortcut for debugIt? Best regards -Tobias

Dear all, After seven month, I got the SqueakTrunkOnSpur job on jenkins back going so that we can see it is working before the release. Sadly, it is not: http://build.squeak.org/job/SqueakTrunkOnSpur/604/console (Some excerpts at the end) Can someone more knowledgeable than me please investigate?

Loading SOUL in Trunk
by marcel.taeumel 24 Jun '15

Hi, everyone! I am trying to load SOUL in the trunk: MCHttpRepository location: 'http://ss3.gemstone.com/ss/SOUL' user: '' password: '' There is a serious name clash with "Environment" but once fixed [1], it comes to the place were the Smalltalk term parser is not able to parse this term: '| newCollection newTerm count startIndex | newCollection := OrderedCollection new. count := 0. startIndex := ?env startUnify: ?length + 1. ?termPointerList listDo: [:aVarPointer | | var | var := (Variable name: ''temp'') setAddress: count. newCollection add: var. var unifyWith: aVarPointer smalltalkValue term inEnv: ?env myIndex: startIndex hisIndex: aVarPointer smalltalkValue envIndex inSource: false. count := count + 1]. ?head = ListTerm ListTermFunctor smalltalkValue ifTrue: [self halt. newCollection add: EmptyListConstant new. newTerm := SoulFactory current makeList new makeListCompound: newCollection] ifFalse: [newTerm := SoulFactory current makeCompound functor: ?head soulUp termSequence: (TermSequence terms: newCollection) astLink: ((HiddenVariable name: SoulFactory uniqueName) setAddress: ?length)]. newTerm definitionRepository: ?rep. ?TermPointer term unifyWith: newTerm inEnv: ?env myIndex: ?TermPointer envIndex hisIndex: startIndex inSource: true. true' It fails at the first "?env". It uses SmaCC and the SmalltalkTermParser looks like generated code. Any ideas how to fix this? Best, Marcel [1] Use this SOUL-Kernel-mt.mcz <http://forum.world.st/file/n4833873/SOUL-Kernel-mt.mcz> and add an empty SouleMethodCompiler >> #parser: .

4.6 regression: stepping Through locks the image solid
by Chris Muller 24 Jun '15

24 Jun '15

Today I noticed Preferences #serverMode. I've never used it, is this still useful? I decided to try setting it in one of my servers to see if it had any effect on its performance. Preferences serverMode "false" Preferences serverMode: true "DNU" Preferences setPreference: #serverMode toValue: true. "do it" Preferences serverMode "false. Huh?" Preferences setPreference: #serverMode toValue: true. "debug it" In the debugger, select Into + Into + Through. It works fine in the 4.5 image, but trunk locks up tightly. It may be due to called code entering a critical: section but I'm not sure. Based on what Marcel described re: extending "Processor activeProcess" to return the effective process, is definitely a suspect.. This is a pretty bad regression from 4.5, because Mutexes are very common and so the image should could easily lock just by normal debugging activity..

[OT] Vi Hart, doing a fun talk.
by Casey Ransberger 24 Jun '15

24 Jun '15

Does anyone recognize the redhead in the front row who seems to be wearing a valid Smalltalk expression on his chest? Or maybe it's Obj-C. Or maybe I'm just reading too much into his shirt. Anyway, if you've never seen any of Vi's videos, she's just absolutely brilliant, and worth paying attention to. She's making math popular. A brick at a time, but isn't that amazing? Thought some of the people here might really dig her. Sorry about being a little off-topic. Also, Bert actually has to watch this if he hasn't seen her videos. I'm requiring that. I won't ever tell you what to do again but this time is for real, man. Required:) https://www.youtube.com/watch?v=U9NhhnnWoTQ Cheers and such, --C

New Cog VMs available
by Eliot Miranda 21 Jun '15

21 Jun '15

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3386 CogVM binaries as per VMMaker.oscog-eem.1370/r3386 Add the ARMv5/ARMv6 Cog Spur JIT VM! Add explicit read barriers to primitives which access an argument as the receiver (i.e. the mirror primitives). Don't check if the actual receiver is used. Simplify failure where appropriate cuz the primitives will be retried. Add -fwrapv to all linux gcc builds (to insist on 2's complement arithmetic) and add makeallclean, making makeall do the dirty build. Provide a -exitonwarn command line switch for the Mac and Unix VMs to allow for CI testing of asserts. Unix: restore the SCCS revision after the version number in -version output. Spur: Remember to count shrink requests Cogit: Fix bug in rewriting compiler primitives on module unload, etc. The old code didn't change the assignment to the primitiveFunctionPointer, which is needed for correct management of failing primitive calls on Spur. Simplify the post compile hook to eliminate the label parameter; this is local to the Cogit. ARM Cogit: Use out-of-line literals for compactness. -- best, Eliot

64-bit image, please
by Chris Cunnington 19 Jun '15

19 Jun '15

Perhaps we could get a 64-bit image to play with? I recall reading it was forthcoming. [1] I have compiled a Linux Stack Spur 64 HT.[2] I’d hate to see WebAssembly [3][4] put Smalltalk in the browser before I know if my compiled stack vm works.
