Description Karolina Surma 2025-05-14 08:32:10 UTC

python-jiter fails to build with Python 3.14.0b1.

This report is automated and not very verbose, but we'll try to get back here with details.

crates/jiter-python/tests/test_jiter.py .Fatal Python error: Segmentation fault

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14-b1/fedora-rawhide-x86_64/09031419-python-jiter/

For all our attempts to build python-jiter with Python 3.14, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/package/python-jiter/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14-b1/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.

Comment 1 Ben Beasley 2025-05-14 11:12:21 UTC

PyO3 0.25 is releasing today with Python 3.14 support. Once it has been fully released and is packaged, we can start to try porting Python extensions written in Rust to the new PyO3 version and see whether they have Python 3.14 issues of their own, or just needed a compatible PyO3.
