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:

Let us know here if you have any questions.

Comment 1 Ben Cotton 2019-08-13 17:04:54 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 2 Ben Cotton 2019-08-13 18:33:59 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to 31.

Comment 3 Miro Hrončok 2019-08-14 22:24:20 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:

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 4 Miro Hrončok 2019-08-21 16:34:34 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-

Comment 5 Miro Hrončok 2019-08-21 17:29:07 UTC
(Python 3.8 has landed in the rawhide buildroot.)

Comment 6 Elliott Sales de Andrade 2019-08-25 22:32:14 UTC
According to koschei, this was due to things other than Python 3.8 (NumPy and Matplotlib changes.)

Comment 7 Antony Lee 2019-09-13 16:27:10 UTC
mplcursors maintainer here.  I can tag a new release, but would prefer if someone could confirm that the current HEAD would pass the fedora build first.

Comment 8 Elliott Sales de Andrade 2019-09-14 00:18:09 UTC
Here are scratch builds of master (bec334245409ab89eb9cf3967328a568fa3d44b6) on Fedora 31 (Python 3.7) and Fedora Rawhide (Python 3.8)

Both pass, so it should be good to go.

Comment 9 Antony Lee 2019-09-15 23:59:31 UTC
0.3.0 has been released to PyPI.

Comment 10 Elliott Sales de Andrade 2019-09-17 08:13:17 UTC
Updated and rebuilt.
