Bug#1001424: python-nest-asyncio: (autopkgtest) needs update for python3.10: TypeError: gather() got an unexpected keyword argument 'loop'

Version: 1.5.1-1
Severity: serious

Dear maintainer(s),

We are in the transition of adding python3.10 to the supported Python
versions [0]. With a recent upload of python3-defaults the autopkgtest
of python-nest-asyncio fails in testing when that autopkgtest is run
with the binary packages of python3-defaults from unstable. It passes
when run with only packages from testing. In tabular form:

pass fail
python3-defaults from testing 3.9.8-1
python-nest-asyncio from testing 1.5.1-1
all others from testing from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of python3-defaults
to testing [1]. https://docs.python.org/3/whatsnew/3.10.html lists
what's new in Python3.10, it may help to identify what needs to be updated.

Hi Paul,

thanks for the bug report - I have prepared an upload of a new upstream
version that includes a fix [2] for Python 3.10 support.
