Hi!
While rebuilding the python related packages against the Python 3.15rc1
version we found that python-cliff builds, but then causes
python-osc-lib to break [1].
This is because the `get_distributions_by_modules` function tries to
read the package metadata, and starting from Python 3.15 this operation
fails when the metadata isn't present (previously invalid reads returned
None). [2]
I've worked around this problem by returning an empty dictionary if the
values can't be read. This is not a proper fix, but simply ignoring data
that was already invalid.
I applied this fix in the sandbox [3] to be able to build the packages
that depend on python-cliff, please consider applying the patch to
support the upcoming 3.15 version.
Happy hacking,

Description: Gracefully handle metadata errors in packages_distributions
In Python 3.15, importlib.metadata.packages_distributions() raises
MetadataNotFound if any distribution directory on sys.path has missing or
incomplete metadata.
