Advent of Python 3.13
by Karolina Surma 30 Nov '23

30 Nov '23

Hello fellow Fedorans, As many of you know, there's an ongoing yearly effort of integrating a new Python version to Fedora taking place in Copr[0]. This time we aim to rebuild over 4000 packages and we couldn't possibly do it without you. There have already been over 300 of bugzillas[1] created for packages that fail to build with Python 3.13.0 alphas - and, I need to add, almost 90 of them already fixed. I'd love to thank everyone who jumped at the early bugzillas and helped drive the progress of the rebuild. We're grateful and appreciate your time and effort. As there's the end of the year coming, various advents of... start to appear. I'd like to propose (only half-jokingly) another one: Advent of Python 3.13. How would that work? We publish the status of rebuild online: https://befeleme.github.io/fedora-python-rebuild-status/ Look at a package you're familiar with and has got a red or orange dot 🔴/🟠 - meaning it fails to build. On the Build failures page[2] you can find links to the package in the rebuild Copr and if there's associated bugzilla blocking the main PYTHON3.13 tracker, the link to the ticket. What can you do? - Fix the package (preferably upstream first) - Let upstream know about the issue - If you know the issue comes from Rawhide and is unrelated to Python 3.13, find (or create) a F40FTBFS ticket and set it to block PYTHON3.13 tracker too. - If you've got no clue, ping me (ksurma) or mhroncok in the Matrix channel[3], we'll be happy to cooperate in digging into the issue - If a package is gray ⚪, it means we don't have all its dependencies built yet, so we haven't tried to build it. Feel free to ignore it, but any help with unblocking the dependencies will be welcome. Cheers, Karolina For curious minds - what's currently blocking the rebuild?

Thank you all for your help! I will retire the packages for pyo3 v0.15 from rawhide now. Fabio

Hi Folks, I'm seddik, I have joined Fedora Infrastructure Community in July 2020 as a contributor. So I'm helping with automation and monitoring tasks. I have a little experience on python programming, and would be happy to get involved as much as ever. Please feel free to help me with any documentation, or process related to fedora python contribution. I would love to help/ maintain a python application. I found these links : https://fedoraproject.org/wiki/SIGs/Python#Areas_of_contribution https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&… https://docs.fedoraproject.org/en-US/package-maintainers/How_to_Get_Sponsor… Regards, *Seddik * Nickname (irc / matrix ): *saibug*

I propose sphinx no longer Requires sphinxcontrib-{applehelp,devhelp,jsmath,htmlhelp,serializinghtml,qthelp}
by Miro Hrončok 22 Nov '23

22 Nov '23

Hello Pythonistas. In https://src.fedoraproject.org/rpms/python-sphinx/pull-request/59 I propose a change that would make the runtime requirements of: - python3-sphinxcontrib-applehelp - python3-sphinxcontrib-devhelp - python3-sphinxcontrib-jsmath - python3-sphinxcontrib-htmlhelp - python3-sphinxcontrib-serializinghtml - python3-sphinxcontrib-qthelp ...optional (Recommends) in python3-sphinx. Packages that need those would need to BuildRequire them specifically, as proposed in: - https://src.fedoraproject.org/rpms/xca/pull-request/1 - https://src.fedoraproject.org/rpms/python-django-haystack/pull-request/1 - https://src.fedoraproject.org/rpms/pykka/pull-request/3 - https://src.fedoraproject.org/rpms/extra-cmake-modules/pull-request/2 The change has been offered upstream, but I suppose it will take a while before it is actually landed there. Let me know if you think this needs more discussion before shipping it. (The change is only intended for Fedora 40+ and ELN.) -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Stale PEP 541 request
by Nils Philippsen 22 Nov '23

22 Nov '23

Hi! About three weeks ago, I filed a PEP 541 request for rpmautospec in the PyPI repo[1] – I believe, the name was blocked to prevent squatting – but so far there is no activity in the ticket other than mine. This blocks me from doing a release on PyPI (as per the Python Packaging Guidelines[2]), can anybody from the Python SIG help me out here? Thanks, Nils [1]: https://github.com/pypi/support/issues/3312 [2]: https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_pypi_par… -- Nils Philippsen / Senior Software Engineer / Red Hat PGP fingerprint: D0C1 1576 CDA6 5B6E BBAE 95B2 7D53 7FCA E9F6 395D

Rust bindings for Python (pyo3 versions <0.19, cpython) broken with Python 3.12
by Fabio Valentini 13 Nov '23

13 Nov '23

Hello Pythonistas and Rustaceans, TL;DR: Only PyO3 v0.19.2 (and later) will ever properly support Python 3.12. Port your Python projects to v0.19 **NOW**. Older versions of PyO3 (especially pyo3 v0.15, v0.16, v0.17, and v0.18) are *not* compatible with Python 3.12 due to some ABI changes in unicode strings and behavioural changes wrt/ "immortal" objects. This also affects all current versions of the "cpython" Rust bindings, with no timeline for Python 3.12 support. As far as I can tell, extensions that use pyo3 < v0.19 or the "cpython" bindings can (and likely will) not work as expected on Python 3.12 if they use the affected APIs (either by producing garbage data in strings that are passed over the FFI boundary, or by crashing). There are applications in Fedora that still rely on *ancient* versions of PyO3, potentially affected by this: - cpython: mercurial - pyo3 v0.15: fapolicy-analyzer, python-bcrypt, python-cryptography - pyo3 v0.16: python-y-py - pyo3 v0.17: unused compat packages, will be retired - pyo3 v0.18: matrix-synapse I *stongly* recommend to move all of these packages to pyo3 v0.19 in Rawhide as soon as possible. I will try to submit pull requests with the required changes for affected packages (except mercurial, since there's no version of the "cpython" crate that supports Python 3.12 in sight). There's already a few packages that depend on pyo3 v0.19, which I will rebuild in rawhide for pyo3 v0.19.2, which has much better support for Python 3.12 than v0.19.0 and v0.19.1 (breezy, python-rpds-py, orjson) unless there are any objections. As soon as no packages depend on the compat packages for old versions of pyo3 any longer, I will retire them from Rawhide (and F39, depending on the timing), since they will never work with Python 3.12 and nothing should use them. I've added <package>-maintainers(a)fedoraproject.org for all these packages to the CC of this message. Fabio Rust SIG / PyO3 maintainer in Fedora
