…s in a path Removes a pathlib-specific implementation of `realpath()` that's mostly copied from `ntpath` and `posixpath`.
… when a new `strict=True` keyword-only argument is passed.
There was a problem hiding this comment.
Pull request overview
This PR adds a strict keyword-only parameter to os.path.realpath() to control error handling when encountering non-existent paths or symlink loops. When strict=True, OSError is raised for these conditions; when strict=False (default), the function behaves as before, resolving paths as far as possible.
Key changes:
- Added
strictparameter toos.path.realpath()in both POSIX and Windows implementations - Refactored
pathlib.Path.resolve()to useos.path.realpath()instead of custom resolution logic - Added comprehensive test coverage for strict mode behavior in both test suites
- Updated documentation with clear explanation of the new parameter
