bpo-43757: Make pathlib use os.path.realpath() to resolve symlinks in a path (GH-25264) 
Also adds a new "strict" argument to realpath() to avoid changing the default behaviour of pathlib while sharing the implementation.

bpo-39899: Don't double-check directory name if we're requesting the current user's home directory in ntpath.expanduser() (GH-25277) 2021-04-09 22:28:15 +01:00
Barney Gale 3f3d82b848
bpo-39899: os.path.expanduser(): don't guess other Windows users' home 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.

bpo-33721: Make some os.path functions and pathlib.Path methods be tolerant to invalid paths. (#7695) 
Such functions as os.path.exists(), os.path.lexists(), os.path.isdir(),
os.path.isfile(), os.path.islink(), and os.path.ismount() now return False
instead of raising ValueError or its subclasses UnicodeEncodeError
and UnicodeDecodeError for paths that contain characters or bytes
unrepresentative at the OS level.

Brian Curtin ae57cec791 Fix #16788. Add samestat to Lib/ntpath.py 2012-12-26 08:22:00 -06:00
Brian Curtin 490b32a397 Fix #11939. Set st_dev attribute on Windows to simplify os.path.samefile. 
By setting the st_dev attribute, we can then remove some Windows-specific
code and move os.path.samefile/sameopenfile/samestat to Lib/genericpath.py
so all platforms share the same implementation.

Brian Curtin 95d028fd18 Correction to 88e318166eaf - Issue #11583 
Rather than wrapping the C _isdir function in a Python function,
just import the C _isdir function directly. Additionally, add in the
docstring which was left out.

Brian Curtin 9c669ccc77 Fix #11583. Changed os.path.isdir to use GetFileAttributes instead of os.stat. 
By changing to the Windows GetFileAttributes API in nt._isdir we can figure
out if the path is a directory without opening the file via os.stat. This has
the minor benefit of speeding up os.path.isdir by at least 2x for regular
files and 10-15x improvements were seen on symbolic links (which opened the
file multiple times during os.stat). Since os.path.isdir is used in
several places on interpreter startup, we get a minor speedup in startup time.
