A/B Testing the latest VM on the Pharo repository PRs
by Guillermo Polito Sept. 14, 2022

Sept. 14, 2022

Hi all, TL;DR; I propose we start testing the latest VMs on PRs to the Pharo repository in a "semi-randomâ way. The idea is to earn some confidence while having a small impact on all of you. ==== We need to slowly start pushing the latest VM version, right now hosted in the pharoX branch of the VM repository. This branch so far has all our latest work on the VM for at least one year. Some highlights Interpreter variable auto-localization (Feat/automatic localizationÂ pharo-vm#371 <https://github.com/pharo-project/pharo-vm/pull/371>) Slang cleanups and improvements (Clean slang warningsÂ pharo-vm#413 <https://github.com/pharo-project/pharo-vm/pull/413>, Fix while statement printingÂ pharo-vm#265 <https://github.com/pharo-project/pharo-vm/pull/265>, CastÂ pharo-vm#230 <https://github.com/pharo-project/pharo-vm/pull/230>, Clean slang warningsÂ pharo-vm#413 <https://github.com/pharo-project/pharo-vm/pull/413>, Switch translation to CAST, and testsÂ pharo-vm#311 <https://github.com/pharo-project/pharo-vm/pull/311>, Add several CAST translations and testsÂ pharo-vm#307 <https://github.com/pharo-project/pharo-vm/pull/307>, Fix type inference testsÂ pharo-vm#291 <https://github.com/pharo-project/pharo-vm/pull/291>) SIMD support in the JIT (Speed up object initialization in AArch64 using SIMD instructionsÂ pharo-vm#421 <https://github.com/pharo-project/pharo-vm/pull/421>, SIMD bytecodesÂ pharo-vm#444 <https://github.com/pharo-project/pharo-vm/pull/444>) Initial work on the perm space (Composed image formatÂ pharo-vm#377 <https://github.com/pharo-project/pharo-vm/pull/377>, Composed image format: C translationÂ pharo-vm#388 <https://github.com/pharo-project/pharo-vm/pull/388>, Refactoring of Snapshot and Loading of ImagesÂ pharo-vm#372 <https://github.com/pharo-project/pharo-vm/pull/372>, Perm space on imageÂ pharo-vm#416 <https://github.com/pharo-project/pharo-vm/pull/416>, New & old remembered setsÂ pharo-vm#418 <https://github.com/pharo-project/pharo-vm/pull/418>) Many many bugfixes â¦ To not disrupt anybodyâs work, I propose to make some kind of AB testing on the CI, only impacting PRs to the Pharo repository. odd builds (1,3,5,â¦) use the latest VM even builds (2,4,6,â¦) use the stable VM This will make sure that: the latest VM will be tested in a complex scenario (load code, run testsâ¦) people that have a problem can re-run their builds to get a stable run Iâve made the following PR that follows this idea https://github.com/pharo-project/pharo/pull/11678 G

Equality/Hash Modification and Image Rehashing
by sean＠clipperadams.com Sept. 7, 2022

Sept. 7, 2022

>From Pharo Discord: IIUC when I change the comparison behavior of a class (i.e. reimplement #= and #hash), sets containing those objects start acting oddly e.g. happily storing duplicates of equal objects and failing to find objects they contain. A solution seems to be Set allSubInstances do: #rehash. Is my understanding correct? If so, I find it odd that I've been using and researching Smalltalk for well over a decade and I never remember reading/hearing about this. I wonder if it can be baked into the IDE somehow e.g. via a critic... And stephan responded: > The mailing list posts about that I remember were at the time where the number of object bits used for the hash were increased. --- Following up on his clue, I found [this old post](https://lists.pharo.org/empathy/thread/LKCE5UXYPXPLVOGNZYW64BWHYJY5NM… "this old post"), which seems to confirm my suspicion. This seems like a serious trap for users to fall into (Iâm having flashbacks to my C++ days lol). So, can/should we somehow handle this in the IDE? Something like a refactoring (that has a confirmation window) that gives you the choice to rehash image collections when redefining these methods? In a 1GB image, \`Set allSubInstances do: #rehash\` is almost instantaneous and \`Dictionary allSubInstances do: #rehash\` takes several seconds.

Smalltalks Workshop 2022: call for papers!
by Mariano Martinez Peck Sept. 5, 2022

Sept. 5, 2022

Greetings everyone, This year, in addition to traditional technical talks, FAST has organized a Workshop [1] where researchers are invited to submit papers, which will be evaluated by specialized reviewers. We have chosen the Workshop format to let authors get early qualified feedback of their work without preventing them from presenting in other conferences or publications, since this format does not imply exclusive submission. [1] https://smalltalks2022.fast.org.ar/registration/call-for-papers Greetings, -- Mariano Martinez Peck Email: marianopeck(a)gmail.com Twitter: @MartinezPeck LinkedIn: www.linkedin.com/in/mariano-martinez-peck <https://www.linkedin.com/in/mariano-mart%C3%ADnez-peck/> Blog: https://marianopeck.wordpress.com/

Change notification: squeaksource.com migration to new service provider today
by David T. Lewis Aug. 31, 2022

Aug. 31, 2022

As part of an overall project to move squeak.org services to a new service provider (hetzner.com) the https://squeaksource.com server will be migrated today, 31 August, beginning at 20:00 UTC. Due to time required for DNS updates to propagate, the change will take effect over a number of hours (expect up to one day). This is the general purpose squeaksource.com server, and does not affect http://source.squeak.org, which will be migrated separately at a later date. What you need to know: For most people, no change will be noticed. Read access to repositories will continue with little or no interruption. If you are committing updates to existing projects, there is a risk of those updates being committed to the "wrong" server during the transition period. No data or files will be lost, but some updates may need to be re-applied. The squeaksource.com administrator will be watching for this and will either fix any missing updates or request the affected project administrator to do so. If you are a project administrator or if you are planning to create a new project on squeaksource.com, please avoid making changes during the transition period. In the event of problems, please report the concern here on the squeak-dev list. If you do not have access to that list, you can report the concern to lewis(a)mail.msen.com. Dave

Platform Packages vs. Git Branches
by sean＠clipperadams.com Aug. 30, 2022

Aug. 30, 2022

Iâve always supported multiple platforms (e.g. different Pharo versions) via packages like MyProject-Plaform-Pharo9. Thinking back, the primary reason is that is how I saw it done by other projects. Also, I adopted the practice well before git was in wide use in the Pharo world. However, Jan Bliznicenko recently suggested an alternate workflow which sounds like how Pharo itself is managed: use git branches, with the primary branch supporting only latest Pharo, and other branches only getting critical bug fixes backported. Not sure how that would work for projects that support other dialects e.g. Gemstone and Squeak, since there would then be multiple âlatest versionsâ. Iâm interested in opinions about these options as I feel that Magritte is an important community asses and want to keep it compatible on as many platforms as possible (with as little work as possible)! I also get the feeling that many people keep ancient systems in production, and I wonder which they would prefer - a project that is stable on a Pharo version (more or less) when that version is released or having the latest commits, especially bug fixes. Thoughts?
