Bug 1898727

python-poetry-core fails to build with Python 3.10.0a2.

        try:
            wheel_data = decode(zip.read("extended-0.1.dist-info/WHEEL"))
    
>           assert (
                re.match(
                    """(?m)^\
    Wheel-Version: 1.0
    Generator: poetry {}
    Root-Is-Purelib: false
    Tag: cp[23]\\d-cp[23]\\dm?u?-.+
    $""".format(
                        __version__
                    ),
                    wheel_data,
                )
                is not None
            )
E           AssertionError: assert None is not None
E            +  where None = <function match at 0x7efe31006940>('(?m)^Wheel-Version: 1.0\nGenerator: poetry 1.0.0\nRoot-Is-Purelib: false\nTag: cp[23]\\d-cp[23]\\dm?u?-.+\n$', 'Wheel-Version: 1.0\nGenerator: poetry 1.0.0\nRoot-Is-Purelib: false\nTag: cp3_10-cp3_10-manylinux2014_x86_64\n')
E            +    where <function match at 0x7efe31006940> = re.match
E            +    and   '(?m)^Wheel-Version: 1.0\nGenerator: poetry 1.0.0\nRoot-Is-Purelib: false\nTag: cp[23]\\d-cp[23]\\dm?u?-.+\n$' = <built-in method format of str object at 0x7efe2f79a5d0>('1.0.0')
E            +      where <built-in method format of str object at 0x7efe2f79a5d0> = '(?m)^Wheel-Version: 1.0\nGenerator: poetry {}\nRoot-Is-Purelib: false\nTag: cp[23]\\d-cp[23]\\dm?u?-.+\n$'.format


This is closely related to bz1891840 but a bit different.

The test asserts the following regex:  cp[23]\\d-cp[23]\\dm?u?-.+

But that doe snot work with double digit Python minor version. Regardless if this ends up cp3_10 or cp310.


I've reported it to upstream: https://github.com/python-poetry/poetry-core/issues/110



For the build logs, see:

For all our attempts to build python-poetry-core with Python 3.10, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/python-poetry-core/

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 3.10:
https://copr.fedorainfracloud.org/coprs/g/python/python3.10/

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
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.
