Hi,

I screwed up python-async-timeout in Fedora 34 by pushing it from 3.x to 4.x.
I should not have bumped the major without significant more testing and
talking to people. I rushed it through and caused lots of breakage.

So first, I really do want to apologise for the mess I caused. And I'll
make sure it won't happen again. I will do some community service by
doing a bunch of outstanding package reviews we currently have open.


The biggest issues is breaking python-aiohttp. I've spend some time in
looking at bumping python-aiohttp to 3.8.x to match it up with
python-async-timeout 4, but both the python-aiohttp test cases fail as
well as my own $dayjob code using it.

There are a four more (known) packages that fail based on the API change
that could probably be fixed, but there would also be other python code
outside fedora that might fail on the API change. And since my attempted
use of the newer version of python-aiohttp in fedora 34 is also causing
issues, I think the safer choice is to roll back python-async-timeout
from 4.x to 3.x using Epoch.

An alternative could be to fixup python-aiohttp 3.7.x to work with
async-timout 4.x, but that still involves two API changes inflicted on
others as well:

- Support timeout.deadline
- Port timeout.timeout property that returns a relative timeout
  based on the timeout object creation time to the absolute
  timeout.deadline instead.

Although possibly a wrapper patch could be written to handle this to
give 3.x API compatibility back. But it would still require package
requirements that require < 4 to be respun to allow version 4.

Another alternative is to investigate why python-aiohttp 3.8.x %check
fails on wait_from() et all in f34/f35 but not in rawhide and port what
is needed there back to f35/f34. I looked at this briefly, and it is not
clear to me what is failing, and I would need help to look into this.


I do think undoing python-async-timeout with an Epoch is ugly but the
best path forward. I think due to the pythondist specific requires, we
would not need to carry the epoch into f35 or rawhide to preserve EVR?

I am looking for some guidance to ensure I don't break things even more
and I apologise for the extra work that I have and am causing everyone.

Paul
