18d845c9 - Fix _is_package_available reporting available without a version (#46125)

Fix _is_package_available reporting available without a version (#46125) * Fix _is_package_available reporting available without a version When find_spec resolves to a namespace package (e.g. a directory on sys.path that shadows an optional PyPI dependency), the metadata fallback returns getattr(package, "__version__", "N/A"). Returning (True, "N/A") then breaks downstream callers that pass the value to version.parse(). * Add regression test for namespace-shadow case in _is_package_available * Require missing __file__ as well to mark a package unavailable A versionless-but-installed package (e.g. rich) has no __version__ but still sets __file__; only a PEP 420 namespace package (a bare dir shadowing on sys.path) has neither. Gate on both so real installs and frozen builds stay available. * Consolidate _is_package_available edge case tests --------- Co-authored-by: bob <amailok2@gmail.com>
