Description Miro Hrončok 2019-08-20 23:21:23 UTC

python-oslo-utils-3.40.3-3.fc32 failed to rebuild with Python 3.8.

See https://koji.fedoraproject.org/koji/buildinfo?buildID=1359867

The error is:

This issue is blocking the Python 3.8 rebuilds. If this package won't build with 3.8, it won't be installable, along with all its dependent packages, after the side tag is merged.
Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well. 


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/

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

Comment 1 Alfredo Moralejo 2019-08-21 16:33:35 UTC

Upstream fix for one of the issues https://review.opendev.org/#/c/677770/ . I will patch in distgit.

Still investigating second one.

Comment 2 Miro Hrončok 2019-08-21 16:35:10 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 3 Miro Hrončok 2019-08-21 17:29:14 UTC

(Python 3.8 has landed in the rawhide buildroot.)

Comment 4 Alfredo Moralejo 2019-08-22 15:48:08 UTC

Fixed in https://src.fedoraproject.org/rpms/python-oslo-utils/c/3eb1e84abf6cc0ea20333e70a20ba96bfdd6adce?branch=master
