Bug#1009115: pythonpy: (autopkgtest) needs update for python3.10: cannot import name 'Iterable' from 'collections'

Thu, 07 Apr 2022 04:15:18 -0700 

Source: pythonpy
Version: 0.4.11b-3
Severity: serious
Tags: sid bookworm
User: debian...@lists.debian.org
Usertags: needs-update
User: debian-pyt...@lists.debian.org
Usertags: python3.10
Control: affects -1 src:python3-defaults

Dear maintainer(s),
We are in the transition of making python3.10 the default Python versions [0]. With a recent upload of python3-defaults the autopkgtest of pythonpy 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    3.10.4-1
pythonpy               from testing    0.4.11b-3
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. https://docs.python.org/3.9/library/collections.html says: 
"""
Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9. 
"""
Time to move on.
