Description Tomáš Hrnčiar 2021-11-11 09:24:28 UTC
python-altgraph fails to build with Python 3.11.0a2.

Traceback (most recent call last):
  File "/builddir/build/BUILD/altgraph-0.17/setup.py", line 432, in <module>
    metadata = parse_setup_cfg()
               ^^^^^^^^^^^^^^^^^
  File "/builddir/build/BUILD/altgraph-0.17/setup.py", line 216, in parse_setup_cfg
    fp = open(nm, "rU")
         ^^^^^^^^^^^^^^
ValueError: invalid mode: 'rU'

Changes in the Python API
    open(), io.open(), codecs.open() and fileinput.FileInput no longer accept 'U' (“universal newline”) in the file mode. This flag was deprecated since Python 3.3. In Python 3, the “universal newline” is used by default when a file is open in text mode. The newline parameter of open() controls how universal newlines works. (Contributed by Victor Stinner in bpo-37330.)

For all our attempts to build python-altgraph with Python 3.11, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.11/package/python-altgraph/

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 3.11:
https://copr.fedorainfracloud.org/coprs/g/python/python3.11/

Let us know here if you have any questions.

Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11.
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.

Turns out I already fixed this two years ago for Python 3.9 via an issue on this tracker :)

https://github.com/ronaldoussoren/altgraph/pull/14

Released in v0.17.1.

This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle.
Changing version to 36.

Hello,

This is the first reminder (step 3 from https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs).

If you know about this problem and are planning on fixing it, please acknowledge so by setting the bug status to ASSIGNED. If you don't have time to maintain this package, consider orphaning it, so maintainers of dependent packages realize the problem.
