(This is a mass bug update. Forgive me if things are not 100% accurate for this one.)

At this moment, your package still requires Python 3.6. This will cause broken upgrades to Fedora 29. Please prioritize this rebuild.

Let me know if you need help from the Python maintenance team figuring out why the package FTBFS.

Consider orphaning the package if you don't have time for it.

Consider retiring the package if upstream is dead and nothing depends on it in Fedora.

If you are blocked by other packages (I've recently tried to set the Bugzilla metadata to reflect that), consider helping there as well. Thank you.

This might be an unittest regression introduced by https://github.com/python/cpython/pull/4496

I'll try to prep a shorter reproducer and will open upstream bug.

Hi,

I already reproduced it with Python 3.7 locally. I hope I will propose a patch in upstream soon.

Actually, ryu does some not so common things in test_lib.add_method, not sure if this is supported, but a fix might be:

diff --git a/ryu/tests/test_lib.py b/ryu/tests/test_lib.py
index 380297b..b30a144 100644
--- a/ryu/tests/test_lib.py

Or rather:

I just did patch in upstream rye code to fix this issue: https://github.com/osrg/ryu/pull/75

Patch for ryu is merged. Master branch should build fine on py 3.7 now.
I will now ask ryu developers when new version with this fix can be released.

Could you please backport the patch?

There is PR do bump python-ryu to 4.27 in rawhide: https://src.fedoraproject.org/rpms/python-ryu/pull-request/4 - this should works fine with py37
