Sockets not working under heavy VM load?
by Pavel Krivanek Oct. 3, 2023

Oct. 3, 2023

Hi, we have some performance issues with Glorp over P3 and, after some investigation, I have a theory that could explain it. And I would like to know your opinion if it is correct. To reproduce this issue, you can try something easy. Just create a process with normal or higher priority that will try to read something from a socket. And, in parallel, do in a separate thread an operation that takes all the processor time for several seconds. ```` [ 5 seconds wait. Time now traceCr. ZnClient new url: 'https://www.google.com'; get. Time now traceCr. ] forkAt: 60. [1000 timesRepeat: [ 10000 factorial ] ] timeToRun ```` (you may try a different safe server address) The processes run in parallel until the time when the first process tries to obtain data from the socket. Then it hangs and waits until finishing of the second process. My theory is that the VM socket plugin is able to receive incoming data from the connection and save it into the buffer. In the meantime, the reading process is waiting on the socket semaphore. But it looks like the plugin is not able to release the semaphore while the VM is actually doing something. It needs to wait until the VM has nothing useful to do, and then it is finally able to release the semaphores so Pharo processes are resumed and can start to read. Is my theory right? Cheers, -- Pavel

GSoC idea: a code generation model for smalltalk
by Nicolas Anquetil Aug. 21, 2023

Aug. 21, 2023

hello, this paper : "An Empirical Comparison of Pre-Trained Models of Source Code" https://arxiv.org/pdf/2302.04026.pdf studied "19 recently-developed pre-trained models of source code" I am a complete noob in this domain, but wouldn't it be possible to use one of these to train it on smalltalk code and get an advanced code completion tool from that ? nicolas

Ephemerons in P11
by Guillermo Polito March 20, 2023

March 20, 2023

Hi all, For those that may not be following the day-to-day development, you may be interested in that Ephemeron support is now enabled in Pharo 11 for one week or so (VM version 10.0.0, Image build 627). Here are some takeaways and actions to take you may be interested in: To get the latest version: - ZeroConf works out of the box - You must update your VMs in the pharo launcher About compatibility: - old images will run on both the old and latest VMs - new images will only run on the latest VM You can read more on: https://github.com/pharo-project/pheps/blob/main/phep-0003.md Cheers, Guille

Pharo Issue tracker / github "projects" access
by Marcus Denker March 16, 2023

March 16, 2023

Hi, When we started with using github, real issue tracker use (e.g adding tags, closing issues if you are not the ownerâ¦) was only possible with write access to the repository. This new changed (I guess since a while) and we can now invite people to give you more access to make it easy to help. If you are interested â> send a mail to me. This of course makes sense mostly for people who already contributed some PRs. (I will document this on the pharo.org <http://pharo.org/> website and the github reposiitory so this will be east to discover) Marcus

This is the new VM that will be stable for Pharo 11 release, it is also compatible with Pharo 10 images but it is not the default for Pharo 10. It has a lot of changes and improvements, as it is the result of more than a year and a half of improvements, clean-ups, and bug fixes. Changelog v10.0.0 - Slang (Smalltalk to C Translator) - Introducing a C AST to ease the generation of C Code - Having a Pretty Printer for C AST - Translation Tests - Fixing Translation Issues - Clear separation between Slang and VM code - Improving Cast generation - Clean Up: - Remove Old Bytecode Set - Remove Old Block Implementation - Simplification of the Primitives - Removing Unused / Old Code / Dead Code - Cleanup / Removal of Old Unused primitives - Removing Old FFI Implementation - Removing MT Experiment from the code base (Kept in own branch) - Fixing Compilation Warnings - Improving Type annotations to fix bugs in the translation / compilation - Removing Conditional Code on Old Configurations / Features - Renaming Concepts to be inline with Common terminology - Remove Newspeak, Multiple Bytecode and Old Memory Managers - Removing Unused Plugins - Tests - GNUification Tests - Tests for Math primitives including overflow and conversion testing. - Tests for comparison primitives (Equals / Not Equals / Less than / Less or Equals / Greater Than / Greater or Equals) - Testing Primitives for objects Pinned in Memory - Testing Math Primitives for Immediate Classes (SmallFloats / SmallIntegers) - Improving Simulation Infrastructure - Using Sista Bytecode in all Tests - Updating Unicorn version - Improving Machine Code emulation - Testing Image Read / Image Write - Using the same memory map in Tests and Execution - Testing Ephemerons - Become Primitives - Ephemeron - Fix for large ammounts - Make it available - Testing Signal Finalizations - Fixing Become Errors. - Fixing XRay Primitive - Single-Instruction Multiple-Data (SIMD) initial Support: - Initialization of new objects using SIMD (ARM64) - Adding Bytecode Extensions to support SIMD instructions - Adding Vector Registers - Vector Register bytecodes - Auto Localization of Interpreter loop variables and edge detection simplifying development and minimizing code - ImageReader / ImageWriter reification needed for Permanent Space. - Improving the Memory Map of the VM (Using constant positions) - Dependencies Improvements Thanks a lot, and any doubt please let us know.
