Re: Nooby questio - getting hello world out of a headless vm

Hi Guille, Iâm just trying to run the img.image that comes with the pharo-project install. All I want at this stage is to execute `Transcript show: âhello worldâ;cr.` (and have that show on std-out or std-err) and exit. ../Dave On Sep 15, 2022, 8:53 AM -0400, Guillermo Polito <guillermopolito(a)gmail.com>, wrote: > Hi Dave, > > a couple of quick hints that could lead us to a solution: > > - what image are you running on top? what version? > - is the image source file close to the image/VM? > - if the process seems frozen, you can send it the SIGUSR1 signal so it dumps a log of the execution > Â Â kill -SIGUSR1 pid > > That dumps > Â - the native stack > Â - the smalltalk stacks > > That would show you quickly where the problem is, very probably there is an infinite recursion in pharo code. > > G > > > El 14 sept 2022, a las 20:16, David Mason <dmason(a)ryerson.ca> escribiÃ³: > > > > Hi, > > > > Iâve built a stackVM straight out of the box from the instructions atÂ https://github.com/pharo-project/pharo-vmÂ to run some experiments.

Re: Nooby questio - getting hello world out of a headless vm

by Guillermo Polito

Hi Dave, a couple of quick hints that could lead us to a solution: - what image are you running on top? what version? - is the image source file close to the image/VM? - if the process seems frozen, you can send it the SIGUSR1 signal so it dumps a log of the execution kill -SIGUSR1 pid That dumps - the native stack - the smalltalk stacks That would show you quickly where the problem is, very probably there is an infinite recursion in pharo code.

A/B Testing the latest VM on the Pharo repository PRs

by Guillermo Polito

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
