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

[Help needed] 160 method with "sent but not implemented" selectors
by Marcus Denker July 3, 2023

July 3, 2023

This is a not-that important cleanup: It would be nice if we would tag or fix all methods with "sent but not implementedâ selectors if you inspect: SystemNavigation new allSentNotImplementedSelectors you get 160 methods in Pharo12. - some are dead code -> we should remove those - some are methods used for tests - there might be some that are send to objects with a DNU handler -> we should tag them using the < #ignoreNotImplementedSelectors: #()> Pragma - some are bugs -> we should fix those Helo is welcome! If we fix them all we can add a release test and make sure that code like this never is merged. Marcus

[ANN] CBOR for Pharo
by Sven Van Caekenberghe June 23, 2023

June 23, 2023

[ANN] CBOR for Pharo https://github.com/svenvc/CBOR Concise Binary Object Representation (CBOR) is a binary data serialization format. CBOR is based on the JSON data model: a number of primitive types (integers, floats, booleans, strings and null), lists and maps (which represent objects or structures). Being binary, CBOR is more efficient than JSON, which is text based. CBOR also supports binary data and optional extensions (called tags). This implementation has native support for string and epoch based timestamps (DateAndTime) and big integers (Integer). This project contains encoding/decoding support for the half-precision, IEEE 754 16-bit (binary16) floating-point format.
