by Stefan Marr March 2, 2016

March 2, 2016

Call for Papers: ICOOOLPSâ16 ============================ 11th Workshop on Implementation, Compilation, Optimization of OO Languages, Programs and Systems Co-located with ECOOP July 18, 2016, Rome, Italy URL: http://2016.ecoop.org/track/ICOOOLPS-2016 Twitter: @ICOOOLPS The ICOOOLPS workshop series brings together researchers and practitioners working in the field of language implementation and optimization. The goal of the workshop is to discuss emerging problems and research directions as well as new solutions to classic performance challenges. The topics of interest for the workshop include techniques for the implementation and optimization of a wide range of languages including but not limited to object-oriented ones. Furthermore, meta-compilation techniques or language-agnostic approaches are welcome, too. A non-exclusive list of topics follows: - implementation and optimization of fundamental languages features (from automatic memory management to zero-overhead metaprogramming) - runtime systems technology (libraries, virtual machines) - static, adaptive, and speculative optimizations and compiler techniques - meta-compilation techniques and language-agnostic approaches for the efficient implementation of languages - compilers (intermediate representations, offline and online optimizations,...) - empirical studies on language usage, benchmark design, and benchmarking methodology - resource-sensitive systems (real-time, low power, mobile, cloud) - studies on design choices and tradeoffs (dynamic vs. static compilation, heuristics vs. programmer input,...) - tooling support, debuggability and observability of languages as well as their implementations ### Workshop Format and Submissions This workshop welcomes the presentation and discussion of new ideas and emerging problems that give a chance for interaction and exchange. More mature work is welcome as part of a mini-conference format, too. We aim to interleave interactive brainstorming and demonstration sessions between the formal presentations to foster an active exchange of ideas. The workshop papers will be published either in the ACM DL or in the Dagstuhl LIPIcs ECOOP Workshop proceedings. Until further notice, please use the ACM SIGPLAN template with a 10pt font size: http://www.sigplan.org/Resources/Author/ - position and work-in-progress paper: 1-4 pages - technical paper: max. 10 pages - demos and posters: 1-page abstract For the submission, please use the HotCRP system: http://ssw.jku.at/icooolps/ ### Important Dates - abstract submission: April 11, 2016 - paper submission: April 15, 2016 - notification: May 13, 2016 - all deadlines: Anywhere on Earth (AoE), i.e., GMT/UTCâ12:00 hour - workshop: July 18th, 2016 ### Program Committee Edd Barrett, Kingâs College London, UK Clement Bera, Inria Lille, France Maxime Chevalier-Boisvert, UniversitÃ© de MontrÃ©al, Canada Tim Felgentreff, Hasso Plattner Institute, Germany Roland Ducournau, LIRMM, UniversitÃ© de Montpellier, France Elisa Gonzalez Boix, Vrije Universiteit Brussel, Belgium David Gregg, Trinity College Dublin, Ireland Matthias Grimmer, Johannes Kepler University Linz, Austria Michael Haupt, Oracle, Germany Richard Jones, University of Kent, UK Tomas Kalibera, Northeastern University, USA Hidehiko Masuhara, Tokyo Institute of Technology, Japan Tiark Rompf, Purdue University, USA Jennifer B.

[Issue tracker] Please check old issues to prepare for release!
by Marcus Denker March 1, 2016

March 1, 2016

Hello, As you might now, we are in the process of getting Pharo5 stable for a release. One of the things that is always important is to clean the issue tracker: over the year that the new release in in development, lots of issue accumulate. Please, just for the issue you have either opened yourself or where you have been involved in the discussion: -> Is the issue still relevant? Maybe it has been fixed? -> Is it really important to stay open? Sometimes things are just not worth itâ¦ -> Is this really an issue tracker entry? What I mean here is that an issue tracker is not a wish-list. There are so many things I want, but adding an issue is often not helping. âIt would be nice ifââ¦ -> Bugs: Can it be reproduced? How? -> Features: We are in freeze. Likely it should be moved to the âPharo 6â Milestone. We are at 521 open issue as of now, I am sure we can get that number down till we release. At some point (soon) we will make a real âshow stopperâ list for the issue that we have to fix before we can release. Marcus

New Cog VMs available
by Eliot Miranda March 1, 2016

March 1, 2016

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3632. These include 64-bit VMs whose Smalltalk execution and FFI are functional. However, their SocketPlugin is more than somewhat broken. Executing the SocketPlugin tests results in a hard lockup, at least on Mac OS X. This is my next focus for 64-bits. ------------------------------------------------------------------------ CogVM binaries as per VMMaker.oscog-eem.1700/r3632 General: Fix serious bug in jitted perform: primitive. Thanks to Stephane Rollandin for finding and to Levente Uzoni for diagnosing the bug. If the argument count is one greater than the max number of register arguments (2 in Spur, hence perform:with:with:) then the code to remove the receiver and arguments from the stack neglects to remove the receiver and selector. Spur: Fix special selector arithmetic and comparison in the 64-bit Cogit. My original code for genJumpNotSmallIntegersIn:andScratchReg: merely jumped if the tags differed, hence not jumping if both arguments were SmallFloat64s (or both Characters). The new code requires an additional scratch register; hence add genJumpNotSmallIntegersIn:andScratch:scratch:. Fix bug in markAndTraceWeaklingsFrom:. Fields of weaklings may be immediate so must use followOopField:ofObject: not followObjField:ofObject:. Fix https://pharo.fogbugz.com/f/cases/17536/VM-Crash-when-adding-an-iVar-to-a-s… . When weaklings (and when ephemerons) are scan-marked forwarders must be coped with. 64-bit VMs: Fix a bug in printHex: for 64-bits (faulty arithmetic). ThreadedFFIPlugin: Fix the remaining 64-bit issues in the ThreadedFFIPlugin. The X64SysVFFIPlugin now passes the test suite. Hence include the FFI plugin in 64-bit VMs. Make the SqueakFFIPrims plugin internal in the Mac pharo builds. Mac VMs: Have the Mac OS X build install Localizable.strings. Add versions for Newspeak, Pharo and Squeak. Rename the key to SelectImagePanePrompt. Temporarily disable the Serial plugin in the Pharo Mac VM until we can track down the relevant platforms/iOS support for the Pharo extensions. Fix argument access on the iOS platform (Mac OS VMs). _,,,^..^,,,_ best, Eliot

Hi, The Pharo Days 2016 are at the end of this month. We are really looking forward to seeing as many of you as possible. The official registration is not yet online, but we need attendance numbers to plan ahead. We therefor ask you to complete the following Doodle if you plan on coming: http://doodle.com/poll/rsc86cqzxbgwr9tr There are 3 time slots: first day, social diner on the first evening, and second day. The schedule and list of talks is not yet final, but a draft is already available: http://pharodays2016.pharo.org At least one slot is not yet defined, feel free to make a suggestion for a topic you would find interesting. In the afternoon, you have the opportunity to do informal, demo style presentations of your work to small groups. Regards, The Pharo Board

removing of TestReviver
by Pavel Krivanek March 1, 2016

March 1, 2016

Hi, TestReviver that is a part of HudsonBuildTools20 and it is a tool that can process Fuel files generated by CI server. It is an UI tool dependent on Spec so it adds some mess to headless images without GUI that need to use HudsonBuildTools for SUnit reports. I propose to remove it from the standard image and move it to a separate SmalltalkHub project. It is not used directly in Pharo and will be easy to load it from the Catalog by people who need such functionality. Cheers, -- Pavel
