Description Karolina Surma 2023-10-23 12:05:13 UTC
python-bottle fails to build with Python 3.13.0a1.

+ /usr/bin/python3 setup.py build '--executable=/usr/bin/python3 -sP'
Traceback (most recent call last):
  File "/builddir/build/BUILD/bottle-0.12.25/setup.py", line 10, in <module>
    import bottle
  File "/builddir/build/BUILD/bottle-0.12.25/bottle.py", line 37, in <module>
    import base64, cgi, email.utils, functools, hmac, itertools, mimetypes,\
ModuleNotFoundError: No module named 'cgi'

According to https://docs.python.org/3.13/whatsnew/3.13.html

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

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.

Issue is known upstream and there is an issue in the tracker indeed: https://github.com/bottlepy/bottle/issues/1403

There is some discussion there, but no solutions out yet. The solution (as per issue) may not be too obvious as bottle has a "zero dependencies" design goal so just using `multipart` would not fit into this.

Waiting to see if anything will move there (will ping the issue)

Comment 2 Aoife Moloney 2024-02-15 23:00:22 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle.
Changing version to 40.
