[This bug is targeted to the upcoming trixie release]

The package build-depends or depends on python3-pkg-resources, which is
deprecated upstream. Details can be found at

https://setuptools.pypa.io/en/latest/pkg_resources.html

Use of pkg_resources is deprecated in favor of importlib.resources,
importlib.metadata and their backports (importlib_resources, importlib_metadata).
Some useful APIs are also provided by packaging (e.g. requirements and version
parsing). Users should refrain from new usage of pkg_resources and should work
to port to importlib-based solutions.

Python 3.12 in unstable provides both importlib_resources and
importlib_metadata, so no additional dependencies on those packages are needed.

The trac package still uses the pkg_resources module.

Raising the severity of this issue. At the end of the
year 2025, raising the severity again to serious.

If the package is a namespace package, then please lower
the severity again to normal.

We believe that the bug you reported is fixed in the latest version of
trac, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1083806@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Dear Maintainer,

I use Trac as a fastcgi service with lighttpd and I still run into an
import of pkg_resources when starting it. Log extract from my webserver
logs:

ModuleNotFoundError: No module named 'pkg_resources'
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/trac/web/fcgi_frontend.py", line 23, in <module>
    from trac.web.main import dispatch_request
  File "/usr/lib/python3/dist-packages/trac/web/main.py", line 39, in <module>
    from trac.env import open_environment
  File "/usr/lib/python3/dist-packages/trac/env.py", line 43, in <module>
    from trac.loader import load_components
  File "/usr/lib/python3/dist-packages/trac/loader.py", line 21, in <module>
    from pkg_resources import working_set, DistributionNotFound, \
                              VersionConflict, UnknownExtra


This can be fixed by changing the line in loader.py, and using
"from trac.pkg_resources ..." instead of "from pkg_resources ..."
