Another #PyConUS video that I care about, the #Python Steering Council keynote. I wasn't on stage this year! because I'm no longer on the SC 😂 but they did cover something I care about a lot: Free-threaded Python #PEP703

I've been pestering the SC a lot to say something about the state of it in 3.14, and boy, did they indulge me. Six and a half minutes of the 30 minute keynote is about the efforts to remove the GIL.

Oh look I made it to #PyConUS! Looking forward to talking _a lot_ about free-threaded Python (PEP 703) and not do any mandatory Steering Council or PSF Board things! 😅

Still more than happy to talk _about_ SC and PSF stuff though! But you will probably get a batch of look-how-cool-and-awesome about PEP 703 for free 😂

#Python #PEP703

You know how sometimes a little hobby side-project can get a bit out of hand? An unexpected performance regression on speed.python.org that only showed up on GCC 5 (and 7) led me to set up more rigorous tracking of Python performance when using different compilers. I'm still backfilling data but I think it's pretty awesome to see how much, and how consistently, free-threaded Python performance has improved since 3.13:

🧵🛞 I made a thing!

https://hugovk.github.io/free-threaded-wheels/ tracks how many of the top 360 PyPI packages have free-threaded wheels.

🟢 Green packages (currently 3%) offer has free-threaded wheels

⚪ Uncoloured packages (82%) offer pure-Python wheels

🟠 Orange packages (16%) have no wheels ready for free-threading (yet!)

See also Quansight Labs' https://py-free-threading.github.io/tracking/ for a smaller yet fine-grained tracker that also includes build tools.

🚀🧵🐍 Big thanks to @lysnikolaou of Quansight Labs for helping us get @pillow ready for free-threaded Python 3.13 (we did some work at the @europython sprints).

See https://labs.quansight.org/blog/free-threaded-python-rollout and https://py-free-threading.github.io to learn more.

We also upload nightly free-threaded (cp313t) wheels to help the community test:

And we'll upload them to PyPI as part of the Q3 release in October.

In Python, multithreading has historically faced challenges due to the Global Interpreter Lock (GIL). However, after years of ongoing efforts, the community has achieved a breakthrough with the acceptance of PEP 703.
This talk will delve into the GIL, its origins, and the reasons for its removal.

🐍🧪 Python 3.13.0 is due out in October 2024 and work is underway to implement *experimental support* for PEP 703 "Making the Global Interpreter Lock Optional in CPython".

As the Steering Council noted in their acceptance of the PEP, to succeed it's important to have community support.

I wrote a little guide on how you can help test out the beta in your project, and help us find bugs in CPython:

🎉 Please welcome our two newest Python core developers! 🎈🐍🎈

Sam Gross is the author of PEP 703 and leading the work to remove the GIL

Nikita Sobolev is the fourth most active contributor (since 2020) and was recently made a @ThePSF Fellow.
