Description Karolina Surma 2024-01-05 10:38:17 UTC
python-CacheControl fails to build with Python 3.13.0a2.

+ /usr/bin/pytest
ImportError while loading conftest '/builddir/build/BUILD/cachecontrol-0.13.1/tests/conftest.py'.
tests/conftest.py:12: in <module>

    from cgi import parse_header
E   ModuleNotFoundError: No module named 'cgi'

According to https://docs.python.org/3.13/whatsnew/3.13.html module cgi was removed:

PEP 594: Remove the cgi and cgitb modules, deprecated in Python 3.11.

cgi.FieldStorage can typically be replaced with urllib.parse.parse_qsl() for GET and HEAD requests, and the email.message module or multipart PyPI project for POST and PUT.

cgi.parse() can be replaced by calling urllib.parse.parse_qs() directly on the desired query string, except for multipart/form-data input, which can be handled as described for cgi.parse_multipart().

cgi.parse_multipart() can be replaced with the functionality in the email package (e.g. email.message.EmailMessage and email.message.Message) which implements the same MIME RFCs, or with the multipart PyPI project.

cgi.parse_header() can be replaced with the functionality in the email package, which implements the same MIME RFCs. For example, with email.message.EmailMessage:

from email.message import EmailMessage
msg = EmailMessage()
msg['content-type'] = 'application/json; charset="utf8"'
main, params = msg.get_content_type(), msg['content-type'].params

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.13/fedora-rawhide-x86_64/06865731-python-CacheControl/

For all our attempts to build python-CacheControl with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/python-CacheControl/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.

/usr/lib/python3.13/site-packages/cherrypy/lib/httputil.py:15: in <module>
    from cgi import parse_header

This is a problem in cherrypy.

Comment 2 Miro Hrončok 2024-01-05 10:56:34 UTC
I've opened https://github.com/cherrypy/cherrypy/issues/2014

Comment 3 Aoife Moloney 2024-02-15 23:09:04 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle.
Changing version to 40.

Comment 4 Miro Hrončok 2024-02-27 17:51:39 UTC
There is an open PR in https://src.fedoraproject.org/rpms/python-cherrypy/pull-request/19
