Description Miro Hrončok 2020-01-29 22:23:01 UTC 
python-pybeam fails to build with Python 3.9.0a3. This is not related to Python 3.9, a test dependency is broken:

+ /usr/bin/python3 setup.py test
running test
WARNING: Testing via this command is deprecated and will be removed in a future version. Users looking for a generic test entry point independent of test runner are encouraged to use tox.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01199341-python-pybeam/

For all our attempts to build python-pybeam with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-pybeam/

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 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
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 Ben Cotton 2020-02-11 17:18:09 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.
Comment 2 Neal Gompa 2020-02-12 13:34:09 UTC 
This is currently broken in Rawhide and has broken rpmlint CI.

Error: 
 Problem: conflicting requests
  - nothing provides python3.8dist(construct) < 2.10 needed by python3-pybeam-0.5-4.fc32.noarch
Comment 3 Tomáš Chvátal 2020-02-12 16:52:42 UTC 
It actually builds and tests are passing with new construct; the only change I had to do on openSUSE is:

# do not block the new python-construct
sed -i -e ',<2.10' setup.py
Comment 4 Neal Gompa 2020-02-14 00:16:48 UTC 
Confirmed the same as well.


Sent PR upstream: https://github.com/matwey/pybeam/pull/12
Comment 5 Neal Gompa 2020-02-14 00:28:51 UTC 
Submitted packaging PR to fix this in Fedora: https://src.fedoraproject.org/rpms/python-pybeam/pull-request/3
Comment 6 Neal Gompa 2020-02-14 12:39:34 UTC 
The PR upstream has been merged, and upstream has issued version 0.6.

The packaging PR has been also merged, and new builds have been pushed into Fedora 32 and Rawhide to resolve this issue.

So I guess we're waiting for a Rawhide compose now?
Comment 7 Miro Hrončok 2020-02-14 13:28:55 UTC 
The push to master has triggered a build: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/build/1239608/ -- but it failed because the Koji repo was not accessible for a while. It needs to be manually triggered again from the package page at https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-pybeam/ (any Python SIG member can do that).
Comment 8 Neal Gompa 2020-02-15 10:47:57 UTC 
This issue is now completely resolved:

* Rawhide push: https://koji.fedoraproject.org/koji/buildinfo?buildID=1460916
* Fedora 32 push: https://koji.fedoraproject.org/koji/buildinfo?buildID=1460917
* Python 3.9 rebuild in COPR: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/build/1240662/
