Recent speed improvements in Pharo 9 debugger; remaining key/mouse event latencies
by Shaping May 25, 2020

May 25, 2020

Hi all. Within the last hour or so, the folks on Pharo Discord#Spec (notably @Stepharo, @Esteban Lorenzano, @Steven Costiou, @stephan and anyone else I left out) fixed most of the speed problem in the NewTools debugger in Pharo 9. Its stepping action when stepping into and returning from a method (when rendering a new code pane before selecting the next evaluable) is nearly as fast as stepping within one method. The remaining latency is tiny and much more tolerable compared to what it was. The latency is longest on larger methods that need more rendering time. The cause seems to be speed of rendering with the FreeType2 library or possibly a Morphic bug (but that may have been what was fixed to create the current speed up). The P9 debugger is workable for me. Iâm closer to a port. The only serious remaining latency problems are the already described ones following key events (insert, delete, cursor moves) and mouse clicks. The #Spec folks say that this will be fixed when the event-machinery remaining in the VM is moved to the image. Can someone estimate when this will happen? I would like to beta-test and contribute.

Refactorings/code rewriting
by stephan May 25, 2020

May 25, 2020

When creating Spec2 presenters, I noticed the automated refactorings (create accessors) don't all work. Do we need changes to the slots, or to the rewrite rules there? Stephan

[Mm10s] 2020-05-25
by Esteban Lorenzano May 25, 2020

May 25, 2020

### Last week: * PR to remove enlumineur UI and tests from Pharo because it is not working and is causing problems with the Spec2 0.6 merge. * [Spec2] new merge with P9 * [newtools] profile inspector to see why StHeaderBar rendering is so slow in morphic (and it was because of the use of some font not standard). * [spec2] optimise a bit the application os styles by keeping the defined font instead look for it each time. This speeds up StDebugger a lot :) * [vm] compiling the vm on fedora 32. Some problems around, but I got it building (more or less, I needed to use clang). Now, I have problems with the load of modules (like libgit2). * [spec2] fix a bug on gtk in which labels and images where not responding to events defined in #eventHandler. * [spec2] fix a bug that was preventing some commands on GtkMillerAdapter to be executed correctly * [spec2] fix a bug on toolbar buttons (gtk side) that was causing the vm to crash because sometimes I keep invalid references (this may cause problems later?). * [spec2] code: I made a HUGE refactor on how interactionModel works (now they are real objects, and users need to use one of the existent or implement their own) ### This week (starting 2020-05-25): - work with the new inspector. - fixes on Gtk backend - finish (If possible) the Fedora 32 build

[CfP] MPLR 2020 - 17th International Conference on Managed Programming Languages & Runtimes
by Stefan Marr May 25, 2020

May 25, 2020

======================================================================== Call for Papers MPLR 2020 - 17th International Conference on Managed Programming Languages & Runtimes November 4-6, 2020 in Manchester, United Kingdom https://mplr2020.cs.manchester.ac.uk/ Follow us @MPLR_Conf ======================================================================== The 17th International Conference on Managed Programming Languages & Runtimes (MPLR, formerly ManLang) is a premier forum for presenting and discussing novel results in all aspects of managed programming languages and runtime systems, which serve as building blocks for some of the most important computing systems in use, ranging from small-scale (embedded and real-time systems) to large-scale (cloud-computing and big-data platforms) and anything in between (desktop, mobile, IoT, and wearable applications). This year, MPLR will be held in Manchester, UK, as permitted considering Health and safety concerns. For up-to-date details, check out the conference website: https://mplr2020.cs.manchester.ac.uk/ and follow us on Twitter @MPLR_Conf. The areas of interest include but are not limited to: * Languages and Compilers - Managed languages (e.g., Java, Scala, JavaScript, Python, Ruby, C#, F#, Clojure, Groovy, Kotlin, R, Smalltalk, Racket, Rust, Go, etc.) - Domain-specific languages - Language design - Compilers and interpreters - Type systems and program logics - Language interoperability - Parallelism, distribution, and concurrency * Virtual Machines - Managed runtime systems (e.g., JVM, Android Runtime (ART), V8, LLVM, .NET CLR, RPython, GraalVM, etc.) - VM design and optimization - VMs for mobile and embedded devices - VMs for real-time applications - Memory management and garbage collection - Hardware/software co-design * Techniques, Tools, and Applications - Static and dynamic program analysis - Testing and debugging - Refactoring - Program understanding - Program synthesis - Security and privacy - Performance analysis and monitoring - Compiler and program verification Submission Categories --------------------- MPLR accepts four types of submissions: 1. Regular research papers describing novel contributions involving managed language platforms. Research papers will be evaluated based on their relevance, novelty, technical rigor, and contribution to the state-of-the-art. Format: up to 12 pages, excluding bibliography and appendix 2. Work-in-progress research papers describing promising new ideas, with perhaps less maturity than full Papers. Work-in-progress papers will be evaluated with an emphasis on novelty and the potential of the new ideas instead of technical rigor and experimental results. Format: up to 6 pages, excluding bibliography and appendix 3. Industry and tool papers presenting technical challenges and solutions for managed language platforms in the context of deployed applications and systems. Industry and tool papers will be evaluated on their relevance, usefulness, and results. Suitability for demonstration and availability will also be considered for tool papers. Format: up to 6 pages, excluding bibliography and appendix 4. Posters They will be evaluated similarly to work-in-progress papers. Posters can accompany any submission as a way to provide additional demonstration and discussion opportunities. Format: poster and 1-page abstract MPLR 2020 submissions must conform to the ACM Policy on Prior Publication and Simultaneous Submissions and to the SIGPLAN Republication Policy. See http://www.sigplan.org/Resources/Policies/Republication/ Author Instructions ------------------- Submissions need to use the ACM `acmart` format with the `sigconf` style: https://www.acm.org/publications/proceedings-template If you are using LaTeX, submissions need to use the 'acmart' document class with the 'sigconf' option. For reviewing, please include page numbers in your submission using the LaTeX command `\settopmatter{printfolios=true}`. The standard settings of a 9 point font size and the Libertine/Biolinum font family are to be kept. All submissions need to be in PDF format. MPLR uses single-blind reviewing, i.e., author names are generally included in submissions. Please also ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes are legible. Submission Site: https://mplr2020.cs.manchester.ac.uk/submissions/ Important Dates --------------- Submission Deadline: 12 August 2020 Author Notification: 14 September 2020 Camera Ready: 05 October 2020 Conference Dates: 04-06 November 2020 All deadlines are 23:59 AoE (UTC-12h). AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work. COVID-19 -------- Given the uncertainties of the current situation, we want to assure you that MPRL is going to happen. To increase the likelihood of having a physical conference, we are planning it for November. If this wonât be possible, we are preparing a virtual MPLR, learning from the conferences taking place right now and over the summer. In either case, the submission and reviewing process will happen as outlined to ensure timely feedback and continuity for our research work.
