  /home/jugmac00/Projects/my-all-repos/output_zope/morepath/morepath/.tox/py311/lib/python3.11/site-packages/webob/compat.py:5: DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13
    from cgi import parse_header

Also see:
https://peps.python.org/pep-0594/#cgi

And yes I know - it will take a couple of years until anybody will use 3.14 :-)

Anyhow, seeing the same deprecation warnings with every test run is slightly annoying. If you are ok with the suggested replacement (see pep), I'd create a PR.

webob has bigger problems with cgi than just the parse_header method but that being said I don’t see a big problem with the suggested fix. I would require a little due diligence to ensure that they are actually compatible apis.

Bitter rant: due diligence because the pep isn’t very trustworthy in its analyses from the perspective of the maintainer of a very popular library that’s apparently using a library so unpopular that it’s getting dropped from the stdlib.

Any update for this issue?

The title could now be changed to "ImportError: no such module cgi" :'D

Anyway, the cgi.py of 3.11 at least, contains ~1k lines in one file, of which ~700 lines are actually relevant, there is some unbelievable CGI html output garbage and some logging methods so I can understand why people want it gone, is it license-wise possible to vendor the 3.11 / 3.12 version into WebOb compat?

And with all due respect to Martijn for proposing those replacements; those replacement strategies are already in use in cgi.py as far as I can see and what remains... are those 700 lines of code.

In case there's interest, I've tested installing the legacy-cgi package with Python 3.13.0a3 and all tests pass. Branch is here: https://github.com/spiqueras/webob/tree/py3.13

Python 3.13.0b1 is out, and the cgi removal is "official" now.
