Well that's news to me! This is not hosted under
fp.org so I'm a bit surprised.
It's not, we just hacked this when he started monitoring the Python 3 porting
progress. It's created by Fedora Python SIG without the involvement of Fedora Infra.

I think it was incomplete when I tried that, and I was able to find
one more dependency for the packages I introduced to package the
blockdiag family of packages.
The important bit is to check for both rawhide and rawhide-source.
This should get you a complete set. Except modularity, but that's another story.

Good to know!

A couple days ago I got stuck an extra half hour in a train because of
snow and cleaned up one of the blockdiag dependencies to get a feel
for it [1]. I guess my next question is how to incrementally build all
6 packages without breaking dependencies in Rawhide. Words like koji,
side and tag come to mind but I figured I could ask since I won't make
progress just yet (otherwise I'll browse the docs when I'm ready).
You don't really need a side tag when removing stuff. Just do it incrementally,
maybe with fedpkg chain-build. Let me know if you want more information or me to
do it. We can meet on IRC, but not until next week.
Also one reason why I replied to you (but still, many thanks to
everyone) is that this will remove 6 packages relying on python2-nose,
so I will be looking forward to the moment when %{_bindir}/nosetests
will refer to the py3 version :)
Nosetest is used by 171 Python 2 packages :(
Thanks,
Dridi
