📝 Walkthrough

Walkthrough

The find_wheel() function in src/fromager/finders.py was changed to restrict its directory scan to *.whl files instead of iterating over all directory entries, preventing non-wheel artifacts from being considered matches. Two unit tests were added in tests/test_finders.py: one ensuring a valid .whl is selected when non-wheel files are present, and one ensuring None is returned when only non-wheel files exist.

In `@src/fromager/finders.py`:
- Around line 141-143: The loop in src/fromager/finders.py that iterates over
downloads_dir.glob("*.whl") should skip non-file entries to avoid returning
directories named "*.whl"; update the loop in which "for filename in
downloads_dir.glob('*.whl')" is used to check filename.is_file() before doing
the startswith(base) match and only return filename when filename.is_file() and
str(filename.name).lower().startswith(base.lower()); this ensures only actual
wheel files are selected.
