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

How to reinitialize SpCodePresenter commands?
by stephane ducasse Aug. 24, 2023

Aug. 24, 2023

Hi I wanted to extend SpCodePresenter so I created a new command and I added the new command manually in codeNavigationCommandsGroupWith: aPresenter | group | group := (CmCommandGroup named: 'Code search') asSpecGroup description: 'Search the system from code selection.'; beDisplayedAsSubMenu; yourself. self flag: #TODO. "This looks like a very bad way to do this :P" { KyoBrowseClassCommand . ^^^^ SpBrowseClassCommand. SpBrowseImplementorsCommand. SpBrowseSendersCommand. SpBrowseMethodReferencesCommand. SpBrowseMethodsMatchingStringInsensitiveCommand. SpBrowseMethodsMatchingStringSensitiveCommand. SpBrowseMethodsContainingStringCommand } do: [ :commandClass | group register: (commandClass forSpecContext: aPresenter) ]. ^ group My command worked but when I changed from KyoBrowseClassCommand class >> defaultShortcutKey ^ $k command mac | $k control win | $k control unix to KyoBrowseClassCommand class >> defaultShortcutKey ^ $k command mac , $b command mac | $k control win | $k control unix I could not open the playground So I reverted my changes but I cannot find the way to reinitialize SpCodePresenter S

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
