Python 3.13 support

[mooninite]

Fedora bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=2308168

Short summary: Deluge GTK UI tries to import 'cgi' and it is no longer available in Python 3.13.

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

There are recommendations for its replacement in the above link.

I don't think supporting pre-release versions of python in production software is generally something that is done.

Can you not install 3.10 or 12 and create a venv to run deluge in?

Note that as https://peps.python.org/pep-0594/#deprecated-modules says, cgi module is already marked as deprecated in python 3.11, and even with python 3.12 (on Fedora 40, python3-3.12.5-1.fc40), you can already see the warning as:


$ python --version
Python 3.12.5
$ python -Wdefault /usr/bin/deluge-gtk
....
....
/usr/lib/python3.12/site-packages/deluge/httpdownloader.py:9: DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13

We use 3.10.

There is a proposed patch I would like to RFC.

Have you tested this to work without introducing a breaking change? I'd be very doubtful that until it 3.13 was finalized at least it would be merged, but you can (or if you can't I suppose I could on your behalf) make a PR to the https://github.com/deluge-torrent/deluge for Cas to consider.

Once again, we are using 3.10, so your proposed change while it make it work for you, would have to keep compatibility with our 3.7 and 3.10 tests at the very least.
