Description Karolina Surma 2025-01-28 11:16:11 UTC
python-praw fails to build with Python 3.14.0a4.

Two tests fail with:

__________________ TestReddit.test_check_for_async__disabled ___________________

self = <tests.unit.test_reddit.TestReddit object at 0x7f3af6207110>
caplog = <_pytest.logging.LogCaptureFixture object at 0x7f3af5e4ba80>

    def test_check_for_async__disabled(self, caplog):
        reddit = Reddit(check_for_async=False, **self.REQUIRED_DUMMY_SETTINGS)
        reddit._core.request = self.patch_request
>       loop = asyncio.get_event_loop()

tests/unit/test_reddit.py:65: 
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

self = <asyncio.unix_events._UnixDefaultEventLoopPolicy object at 0x7f3af5e652b0>

    def get_event_loop(self):
        """Get the event loop for the current context.
    
        Returns an instance of EventLoop or raises an exception.
        """
        if self._local._loop is None:
>           raise RuntimeError('There is no current event loop in thread %r.'
                               % threading.current_thread().name)
E           RuntimeError: There is no current event loop in thread 'MainThread'.

According to https://docs.python.org/dev/whatsnew/3.14.html#id3

Removed implicit creation of event loop by asyncio.get_event_loop(). It now raises a RuntimeError if there is no current event loop. (Contributed by Kumar Aditya in gh-126353.)

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14/fedora-rawhide-x86_64/08580950-python-praw/

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

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.

Comment 1 Aoife Moloney 2025-02-26 13:49:15 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.

Comment 3 Fedora Fails To Install 2025-06-20 19:51:15 UTC
Hello,

Please note that this comment was generated automatically by https://pagure.io/releng/blob/main/f/scripts/ftbfs-fti/follow-policy.py
If you feel that this output has mistakes, please open an issue at https://pagure.io/releng/

This package fails to install and maintainers are advised to take one of the following actions:

 - Fix this bug and close this bugzilla once the update makes it to the repository.
   (The same script that posted this comment will eventually close this bugzilla
   when the fixed package reaches the repository, so you don't have to worry about it.)

or

 - Move this bug to ASSIGNED if you plan on fixing this, but simply haven't done so yet.

or

 - Orphan the package if you no longer plan to maintain it.


If you do not take one of these actions, the process at https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs will continue.
This package may be orphaned in 7+ weeks.
This is the first reminder (step 3) from the policy.

Don't hesitate to ask for help on https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/ if you are unsure how to fix this bug.

Comment 4 Fedora Admin user for bugzilla script actions 2025-07-08 01:26:11 UTC
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

Comment 5 Fedora Fails To Install 2025-07-09 13:37:15 UTC
This package has been orphaned.

You can pick it up at https://src.fedoraproject.org/rpms/python-praw by clicking button "Take". If nobody picks it up, it will be retired and removed from a distribution.

Comment 6 Miro Hrončok 2025-08-18 21:10:37 UTC
Automation has figured out the package is retired in rawhide.

If you like it to be unretired, please open a ticket at https://pagure.io/releng/new_issue?template=package_unretirement
