Status of Python 3.13 support #1721
Description
Hello Folks,
Can you please help me understand the support status for the latest python?
It looks like we depend on cgi; apparently via webob and then via webtest which is used in production to validate incoming webhooks
However, cgi is no longer included in python 3.13.
While do have a test-suite running on 3.13 already python-package.yml; I'm not sure that we exercise the full webserving/webob path there.
The [latest PR checks run] (https://github.com/errbotio/errbot/actions/runs/14037314539/job/39298415722#step:5:256) does still show warnings about cgi
/home/runner/work/errbot/errbot/.tox/py/lib/python3.12/site-packages/webob/compat.py:5: DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13
from cgi import parse_headerAre we confident that CI exercises the cgi-ish code paths? Can we run fully on python 3.13

If the webserver doesn't work, the fix may be to depend on
legacy-cgi; python_version >= '3.13'nzlosh commentedon Apr 23, 2025
Good spotting!
I've not seen anyone mention they're actively working on 3.13 support.
legacy-cgisuggests new projects use ASGI or WSGI. PEP-0594 states the cgi module is poorly designed and hard to maintain. The CGI architecture is also criticised as inefficient.It seems to me that the best long term solution for the errbot project would be to migrate away from CGI to ASGI/WSGI, but this requires someone with the skills and time to volunteer and carry out the task to completion.

Thank you. Do you think it could be worth adding
legacy-cgito our dependencies as a stopgap?I can do that, or change things to flag max version is 3.12.
I wouldn't be capable of doing the refactor/migration in the foreseeable future.

If
legacy-cgiget 3.13 support, it seems like a reasonable stopgap until we hit a hard blocker.sijis commentedon May 23, 2025
@lbillinghamwrk if you create a PR to add that dependency for 3.12, I'll merge that in.
Long term, as @nzlosh suggested, a switch to ASGI/WSGI may be the best approach.

Thanks @sijis. I have opened #1729 to address this.
I've tested that
pip install .works on python 3.9 and 3.13.fix(deps): allow webtest to work on python 3.13
