CogVM binaries as per VMMaker.oscog-eem.302/r2749
by Eliot Miranda 29 Oct '13

29 Oct '13

are in http://www.mirandabanda.org/files/Cog/VM/VM.r2749/. CogVM binaries as per VMMaker.oscog-eem.302/r2749 Fix bad performance regression that on certain platforms (linux) results in all send misses causing a discarded PIC creation followed by a slow hash lookup. Fix bug when assigning to some context inst vars from generated methods. Add accessors to document the context inst var access scheme. Fix a compiler warning comparing an error code in cog:selector: Update the BitBltPlugin to include the fast Arm ASM option. Fix type errors in the Cogit that prevent the Cogit working when compiled with clang. Specifically void * pointers are not comparable. Make sure that fetchPointer:ofObject: & isIntegerValue: are declared in cointerp.h. Update the Newspeak version of the VMProfileLinuxSupportPlugin. Improve robustness of the nscogbuild/unixbuild mvm scripts. Add the linux policy change dance to sqUnixVMProfile.c (cf sqUnixHeartbeat.c). Fix a bail_out typo. Change the VMProfileLinuxSupportPlugin to follow symlinks, answering pairs of module name, dereferenced symlink or nil. Fix 3 (!!) bugs in primitiveDLSymInLibrary. -- best, Eliot

MNU: Parser >> #contents
by Frank Shearar 29 Oct '13

29 Oct '13

I'm running with Compiler-nice.274. What's weirder is in that top stack frame (Compiler >> #evaluate:in:to:notifying:ifFailed:logged: the following all show up as red, because they're references to instvars that don't exist: class, sourceStream, context, requestor. That's because the CompiledMethod that's running is not actually the right CompiledMethod! It's from some ancient pre-CompilationCue Compiler instance. Or at least so I suspect because that Compiler instance has a nil 'cue' instvar. If it helps, the PointerFinder says this of the offending context: globals: Environment declarations: IdentityDictionary #World -> PasteUpMorph submorphs: Array 1: SystemWindow model: ObjectExplorer currentSelection: ObjectExplorerWrapper item: CompiledMethod In contrast, PointerFinder on: (Compiler >> #evaluate:in:to:notifying:ifFail:logged:) says: CLASS: SmalltalkImage class superclass: Object class subclasses: Array 445: Compiler class methodDict: MethodDictionary array: Array 39: CompiledMethod.

Call for Participation in the Smalltalk Devroom at FOSDEM2014
by Stephan Eggermont 29 Oct '13

29 Oct '13

Call for Participation in the Smalltalk Devroom at FOSDEM 2014. http://www.fosdem.org, please forward " A devroom for the Pharo, Squeak, Amber, GST, Etoilé, Seaside, Moose Smalltalk projects & Newspeak as derived language. Smalltalk environments offer a very high development productivity, unmatched by their successors. Come do some pair programming with us and experience yourself the advantages of a real OO environment" The meetup will take place Saturday, February 1, 2014, from 9AM until 5PM, building AW. This room has 72 seats, a VGA video projector and wireless internet. More information will be available later. If there are volunteers to record video content, the FOSDEM organization kindly offered to provide needed equipment & instructions. Please let me know if you would be willing to spend some time pointing a camera at a speaker. Proposals on content and format are welcome. People interested in running a session should send me an email at stephan ( @ ) stack ( dot ) nl with 'FOSDEM2014’ in the subject and the following information: - Their name - The project they are associated with - A short bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A abstract describing the session in further detail. - The desired length of the session. - The desired time slot in which they want to hold the session. I will send out updates on a regular basis to the lists and anyone stating his interest. Suggested values for the duration are 55min, 25min, 6m40 (Pecha Kucha). The desired time slot is meant to help you prevent conflicts with other dev rooms in which you might have a talk or your travel arrangements. There are alternative, non smalltalk-specific tracks available: lightning talk and the main track The deadline for submissions is December 31, 23:00 GMT+1. Devroom related URLs: http://www.pharo-project.org http://www.squeak.org/ http://etoileos.com/ http://www.seaside.st/ http://smalltalk.gnu.org/ http://www.moosetechnology.org http://amber-lang.net http://newspeaklanguage.org/ http://www.esug.org First proposal already arrived: Stefan Marr proposed: I could give a presentation on SOM (Simple Object Machine) Smalltalk. I would especially go into detail of the Truffle-based and the RPython (PyPy) based implementations to show modern ways of language implementations with the goal of achieving high performance.
