| | | | | | | | | | | Add `ntpath.isreserved()`, which identifies reserved pathnames such as "NUL", "AUX" and "CON". Deprecate `pathlib.PurePath.is_reserved()`. --------- Co-authored-by: Eryk Sun <eryksun@gmail.com> Co-authored-by: Brett Cannon <brett@python.org> Co-authored-by: Steve Dower <steve.dower@microsoft.com>
* GH-44626, GH-105476: Fix `ntpath.isabs()` handling of part-absolute paths ↵Barney Gale2024-01-131-10/+3
| | | | | | | | | | | | | (#113829) On Windows, `os.path.isabs()` now returns `False` when given a path that starts with exactly one (back)slash. This is more compatible with other functions in `os.path`, and with Microsoft's own documentation. Also adjust `pathlib.PureWindowsPath.is_absolute()` to call `ntpath.isabs()`, which corrects its handling of partial UNC/device paths like `//foo`. Co-authored-by: Jon Foster <jon@jon-foster.co.uk>
* gh-82367: Use `FindFirstFile` Win32 API in `ntpath.realpath()` (GH-110298)박문식2023-10-051-6/+10
| | | | | | | * Use `FindFirstFile` Win32 API to fix a bug where `ntpath.realpath()` breaks out of traversing a series of paths where a (handled) `ERROR_ACCESS_DENIED` or `ERROR_SHARING_VIOLATION` occurs. * Update docs to reflect that `ntpath.realpath()` eliminates MS-DOS style names.

* bpo-46362: Ensure ntpath.abspath() uses the Windows API correctly (GH-30571)neonene2022-01-131-1/+1
| | | This makes ntpath.abspath()/getpath_abspath() follow normpath(), since some WinAPIs such as PathCchSkipRoot() require backslashed paths.
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-49/+63
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
* bpo-43757: Make pathlib use os.path.realpath() to resolve symlinks in a path ↵Barney Gale2021-04-281-1/+3
| | | | | (GH-25264) Also adds a new "strict" argument to realpath() to avoid changing the default behaviour of pathlib while sharing the implementation.

| | | | | | | directories if the basename of the current user's home directory doesn't match their username. (GH-18841) This makes `ntpath.expanduser()` match `pathlib.Path.expanduser()` in this regard, and is more in line with `posixpath.expanduser()`'s cautious approach. Also remove the near-duplicate implementation of `expanduser()` in pathlib, and by doing so fix a bug where KeyError could be raised when expanding another user's home directory.
