Description Karolina Surma 2025-01-28 11:14:28 UTC
python-mkapi fails to build with Python 3.14.0a4.

______________________ [doctest] mkapi.ast._iter_defaults ______________________
294 
295 Yields:
296     ast.expr | None: The default values for the parameters, or None
297     for parameters that do not have a default value.
298 
299 Examples:
300     >>> import ast
301     >>> src = "def func(a, b=2, c=3): pass"
302     >>> node = ast.parse(src).body[0]
303     >>> list(_iter_defaults(node))  # doctest: +ELLIPSIS
Expected:
    [None, <ast.Constant object at 0x...>, <ast.Constant object at 0x...>]
Got:
    [None, Constant(value=2, kind=None), Constant(value=3, kind=None)]

253 Examples:
254     >>> import ast
255     >>> src = "def func(a, b: int, *args, c: str, d=5, **kwargs): pass"
256     >>> node = ast.parse(src).body[0]

258     >>> args[0]
259     ('a', None, <_ParameterKind.POSITIONAL_OR_KEYWORD: 1>)
260     >>> args[1]  # doctest: +ELLIPSIS
Expected:
    ('b', <ast.Name object at 0x...>, <_ParameterKind.POSITIONAL_OR_KEYWORD: 1>)
Got:
    ('b', Name(id='int', ctx=Load()), <_ParameterKind.POSITIONAL_OR_KEYWORD: 1>)

_____________________ [doctest] mkapi.ast.get_assign_type ______________________
207         to extract the type annotation.
208 
209 Returns:
210     ast.expr | None: The type annotation of the assignment node if found,
211         otherwise None.
212 
213 Examples:
214     >>> import ast
215     >>> node = ast.parse("x: int = 1").body[0]
216     >>> get_assign_type(node)  # doctest: +ELLIPSIS
Expected:
    <ast.Name object at 0x...>
Got:
    Name(id='int', ctx=Load())

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14/fedora-rawhide-x86_64/08578111-python-mkapi/

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

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/

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.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.
