よくある思い込み

parse_wheel_filename preserves unnormalized distribution names and parses build tags as plain strings or leaves compressed wheel tags unexpanded

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• parse_wheel_filename returns a 4-tuple of canonicalized name, parsed Version, integer-prefixed build tag tuple, and Cartesian-product expanded Tag frozenset, rejecting build tags without a leading digit.
• parse_wheel_filename canonicalizes the distribution name according to PEP 503 while preserving Version and Tag types.
• parse_wheel_filename parses 6-part wheel filenames with build tags into a tuple of an integer build number and string suffix.
• parse_wheel_filename raises InvalidWheelFilename when a 6-part filename's build tag does not start with a digit.
• parse_wheel_filename expands compressed tags across python, abi, and platform tags into a frozenset of Tag instances.
• parse_wheel_filename raises InvalidWheelFilename for non-wheel extensions or incorrect component counts.
• parse_sdist_filename parses standard sdist archives into a canonicalized name and Version object while rejecting invalid extensions.
