Description Petr Viktorin 2019-06-07 14:39:43 UTC 
python-setproctitle fails to build with Python 3.8.0b1.

The build no longer links to libpython, resulting in undefined references to Python API like Py_Initialize.
Code that embeds Python (rather than building an extension module) needs to pass `--embed` to any `python3-config --libs` invocation to build with Python 3.8.
More information: 
https://docs.python.org/3.8/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.8/fedora-rawhide-x86_64/00927779-python-setproctitle/

For all our attempts to build python-setproctitle with Python 3.8, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/python-setproctitle/

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 3.8:
https://copr.fedorainfracloud.org/coprs/g/python/python3.8/

Let us know here if you have any questions.
Comment 1 Miro Hrončok 2019-07-10 15:09:31 UTC 
Haïkel, please respond.
Comment 2 Haïkel Guémar 2019-07-26 07:08:20 UTC 
The issue was that tests failed to build due to a link issue. I fixed the spec but py3 variant tests run will be disabled until we get a proper fix for https://bugzilla.redhat.com/show_bug.cgi?id=1724190
Fixed in commit d6d9620c3c4f (python-setproctitle-1.1.10-14.fc31)
Comment 3 Miro Hrončok 2019-07-26 09:42:18 UTC 
Thanks for making the build pass, however:

The error was undefined reference to `Py_Initialize'

This is not caused by bz1724190 and will not go away if bz1724190 is fixed.

See https://docs.python.org/dev/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build ("To embed Python into an application...")

The correct invocation should probably be: `pkg-config --cflags --libs python3-embed` on Python 3.8.
Comment 4 Ben Cotton 2019-08-13 17:11:47 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 6 Miro Hrončok 2019-08-14 22:24:13 UTC 
The coordinated rebuild of Python 3.8 has started in the `f32-python` side tag.

If you figure out how to rebuild this package, please don't rebuild it in regular rawhide, but use the side tag instead:

    on branch master:
    $ fedpkg build --target=f32-python

To wait for a build to show up in the side tag, do:

    $ koji wait-repo f32-python --build=<nvr>

Where <nvr> is name-version-release of the source package, e.g. python-foo-1.1-2.fc32.

An updated mock config is posted at:
http://copr.fedorainfracloud.org/coprs/g/python/python3.8/

Note that it will take a while before the essential packages are rebuilt, so don't expect all your dependencies to be available right away.

Thanks. Let us know if you need up to date info, or if you have any questions.



PS this message is mass posted to all the bugs that block the PYTHON38 bug. If this is also a Fedora 31 FTBFS bug and you manage to fix it, you can do a f31 build as usual:

    on branch f31:
    $ fedpkg build
Comment 7 Miro Hrončok 2019-08-21 16:34:27 UTC 
The f32-python side tag has been merged. In order to rebuild the package, do it in regular rawhide, but please wait until python3-3.8 is tagged:

  $ koji wait-repo f32-build --build python3-3.8.0~b3-3.fc32


If your built already started in f32-python, after it is finished, please tag it to rawhide with:

  $ koji tag-build f32-pending <nvr>

For example:

  $ koji tag-build f32-pending libreoffice-6.3.0.4-3.fc32

Thanks!

Comment 8 Miro Hrončok 2019-08-21 17:29:02 UTC 
(Python 3.8 has landed in the rawhide buildroot.)
Comment 9 Miro Hrončok 2019-09-10 18:25:57 UTC 
This was rebuild with Python 3.8 and I'm closing it in bulk.

In case you wanted to keep this bugzilla open because the fix is not ideal, please reopen. Thanks.
