Updated plugin compilation info?

by HernÃ¡n Morales Durand

Dear all, I wrote a stupid debugger plugin and generated the C code using: ProtoDebugInterpreterPlugin translateInDirectory: 'ProtoDebug' asFileReference doInlining: false. I remember time ago I modified a plugins.ext file and then copied necessary C headers to a directory (along with my generated .c from Slang) etc etc. Now where should I put my new .c file? Which command/script do you use to compile the VM with a new plugin? Cheers, HernÃ¡n

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

by Luc Fabresse

Hi Dave, I have no clue what this small (204K) file build/dist/pharo-vm/resources/img.image is. Anyone knows? Regarding you libgit issue, I guess this is because build/dist/lib/libgit2.so.1.4.4 is not there. On my side, if I use (as Guille wrote): $ cmake --build vmbuild --target install external libs are there. I agree that "install" is confusing here or I misunderstood.

About primitiveMethodXray

Hi In CoInterpreter we can find initializePrimitiveTable super initializePrimitiveTable. PrimNumberHashMultiply := 159. self assert: (PrimitiveTable at: PrimNumberHashMultiply + 1) = #primitiveHashMultiply. #(216 253) do: [:pidx| self assert: (PrimitiveTable at: pidx + 1) = #primitiveFail]. self assert: (PrimitiveTable at: 215 + 1) = #primitiveFlushCacheByMethod. PrimitiveTable at: 253 + 1 put: #primitiveCollectCogCodeConstituents; at: 215 + 1 put: #primitiveVoidVMStateForMethod; at: 216 + 1 put: #primitiveMethodXray There is a primitive primitiveMethodXray :) primitiveMethodXray "Lift the veil from a method and answer an integer describing the interior state of its machine code. Used for e.g. VM tests so they can verify they're testing what they think they're testing. 0 implies a vanilla method.

Thanks! That worked. I guess the build/dist/pharo-vm/resources/img.image - which I thought would be a minimal functional image - isnât. I was trying to get the startup .st code working first, and didnât try any other image. I get a bunch of stderr log messages about Â Cannot locate any of #('libgit2.1.4.4.dylib' 'libgit2.1.0.1.dylib' 'libgit2.1.0.0.dylib' 'libgit2.0.25.1.dylib').

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.

Nooby questio - getting hello world out of a headless vm

by David Mason

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. So Iâm trying for a simple Hello world on stdout/stderr. I assumed on headless Transcript would go to some useful place, so I tried, I have a hello.st ----- Transcript show: 'hello world!';cr. "(Smalltalk at: #Transcript) show: 'hello world!';cr." ----- and run-test: ----- #! /bin/sh # # Run it with a headless Pharo: # DIR=~/git/pharo-project/stackVM/build VM=$DIR/vm/Debug/Pharo.app/Contents/MacOS/Pharo #IMAGE=$DIR/dist/pharo-vm/resources/img.image IMAGE=img.image ls -l $VM $IMAGE grep .

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
