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

Need help with conda package - launcher script
by Orion Poplawski 09 Oct '23

09 Oct '23

With the update to conda 23.5.2 and using the pyproject macros, the conda package is no longer producing the /usr/bin/conda-env launcher script which is causing problems. I don't know how I can get that back with the current build system. Any help would be greatly appreciated. Thanks. -- Orion Poplawski he/him/his - surely the least important thing about me IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

16 packages still need a Python 3.12 rebuild, final freeze in 6 days
by Miro Hrončok 02 Oct '23

02 Oct '23

Hello packagers, here is the list of packages that still need a Python 3.12 rebuild for Fedora 39+. Packages on this list have broken dependencies and hence the users of Fedora Linux 39+ cannot install them at all. Moreover, users of Fedora Linux 37 or 38 with the listed packages installed are unable to upgrade to Fedora Linux 39+. We need to either rebuild those packages in Fedora Linux 39+ or retire+obsolete them to clear the upgrade path. Package retirement is not a "punishment" for not fixing the package, it is merely a way to allow our users to upgrade. When a retired package is fixed after Fedora Linux 39 final release, it can be added back to the distribution. The Fedora 39 Final Freeze starts on 2023-10-03 14:00 UTC -- that leaves only 6 days to push updates via Bodhi, meaning they will not be autopushed in time. Please, if you are planning to fix the packages, set low karma limits and ask another packager to test it and add karma. Request freeze exceptions when needed: https://qa.fedoraproject.org/blockerbugs/propose_bug I plan to propose "mass" retirement of the remaining packages without a requested freeze exception and a clear path forward a couple days after the freeze starts, so we have time to ship an updated fedora-obsolete-packages.

Maintainers NEEDINFOed last week. The fix of FTBFS is trivial (BR python3-setuptools, as described in https://bugzilla.redhat.com/2155030 in December 2022).

I'd normally just go ahead and merge the branches myself, but the "fix" was to remove all the tests and add redundant manual Requires, so I am reluctant to do that. python-pyside2 ============== https://bugzilla.redhat.com/2155447 https://bugzilla.redhat.com/2220452 https://bugreports.qt.io/browse/PYSIDE-2388 (WONTFIX) Upstream no longer cares about this pyside2 version.
