Hi!

While preparing the Python 3.15 migration we realized that some Python
packages were shipping broken metadata directories, which leads to
errors when trying to import these directories with code running on
Python 3.15.

To avoid shipping any additional broken directories, dh-python
7.20261019 now throws an error at build-time.

Unfortunately, icoextract is one of the affected packages and fails to
build with the latest dh-python [1].

Most of these errors can be fixed by being more strict with the files
considered for installation. I'll try to submit a patch for this ASAP.

Happy hacking,

Hi Maximiliano,

The traceback from the log shows there was a test failure because PIL
couldn't be imported. I just ran a fresh sbuild in unstable which picked
up the new dh-python with no issue, so I think error is part of the
Python 3.15 transition.

Should this be reassigned to src:pillow?

¡Hola James!

Right, pil was uploaded about the same time I triggered this build in
debusine, and the 3.15 version was built a bit later.

The relevant log is: https://debusine.debian.net/debian/r-python-python3.15/artifact/5126062/

Now building against the correct pil version. The error is:
W: dh_python3 fs:153: No merge driver for dist-info file top_level.txt
E: dh_python3 fs:172: Not everything in 'debian/python3-icoextract/usr/lib/python3.15/dist-packages/icoextract-0.3.0.dist-info' was able to be merged into 'debian/python3-icoextract/usr/lib/python3/dist-packages/icoextract-0.3.0.dist-info'.

You are right that this isn't a serious bug just yet, was it only
occurs when there are at least two python3 supported versions. I'm
changing the severity.
