As a workaround, build --without mypyc. Anyway, this might need a fix in mypy. > Anyway, this might need a fix in mypy. mypy has been updated to avoid deprecated C APIs: https://github.com/python/mypy/commit/c41dbd00718c1e873b7797ed7bf00126fd544df5 There is no release yet including this change. That patch touches files that don't even exist in what we have packaged. I am waiting this out. If desired, we can change the tomli bcond to be dependent on Python version. I decided to disable mypyc on 3.15 in the spec file so we don't have to deal with this now. https://src.fedoraproject.org/rpms/python-tomli/pull-request/28 |
python-tomli fails to build with Python 3.15.0a3. This looks like it may not be an issue in tomli, but rather python-mypy?

You can follow these instructions to test locally in mock if your package builds with Python 3.15: https://copr.fedorainfracloud.org/coprs/g/python/python3.15/ Let us know here if you have any questions. Python 3.15 is planned to be included in Fedora 45. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.15. 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.
