Hi PyPy developers and users, Out of curiosity, are you aware of users of PyPy2.7 not related to RPython and internal PyPy ? Do you have stats about such usage ? Best regards, Pierre

Free-threading and PyPy ?
by PIERRE AUGIER 18 Nov '24

18 Nov '24

Hi, With 3.13, CPython now has an experimental free-threaded mode (PEP 703). I understood from the PEP that the free-threaded mode is pushed in particular by some people working in AI/deep learning (for example with a team working at Meta on PyTorch). I also see that some work is being done in adapting the ecosystem to this new feature https://py-free-threading.github.io/ We will see what will happen in CPython, but if I understood correctly, this mode could become the default in few years for CPython. I now that PyPy devs are currently working on Python 3.11 support (and not yet 3.13!), but I was wondering about the technical feasibility of supporting the free-threaded mode in PyPy? I'm just guessing but it could be very difficult isn't it? Do you think it would be even possible to do that with PyPy? Best regards, Pierre

Minor Bug Report for PyPy
by Denil Bouafia 07 Nov '24

07 Nov '24

Hi PyPy Support, I'm a frequent user of PyPy, and I wanted to let you know about a minor bug I recently encountered. I believe sharing this information might be helpful for your ongoing development and troubleshooting efforts. The code in code1.py, when run, correctly prints "starting" and "done." However, a similar version of this code in code2.py enters an endless loop instead of printing "starting" and finishing as expected. This issue appears to be specific to PyPy and does not occur in standard Python. PyPy version : PyPy 7.3.17 with GCC Apple LLVM 15.0.0 (clang-1500.1.0.2.5) Python 3.10.14 IDE : VSCode Please let me know if you need any further details or logs to investigate this. I appreciate all the work your team puts into maintaining and improving PyPy, and I’m happy to help however I can. Thank you for your time! Best regards, Denil Bouafia
