Serhiy Storchaka 404fa924c3 Issue #16841: Set st_dev on Windows as unsigned long to match its DWORD type. 2013-01-02 18:22:23 +02:00
Victor Stinner e4110dc11f Issue #9644: Fix the encoding used by os.statvfs(): use the filesystem encoding 
with the surrogateescape error handler, instead of UTF-8 in strict mode.

Brian Curtin e3d0b65118 Set st_dev on Windows as unsigned long to match its DWORD type, related to the change to fix #11939. 2013-01-01 12:21:35 -06:00
Brian Curtin 87e63a273c st_dev/st_rdev should be unsigned long as dwVolumeSerialNumber, which it is set to, is a DWORD. This was fixed in #11939 and the overflow was mentioned in #10657 and seen by me on some machines. 2012-12-31 11:59:48 -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.

Victor Stinner 4e7d2d481a Issue #15478: Oops, fix regression in os.open() on Windows 
os.open() uses _wopen() which sets errno, not the Windows error code.
 2012-11-05 01:20:58 +01:00
Victor Stinner afe1706457 Issue #15478: Use source filename in OSError, not destination filename 
And other fixes for Windows:

 * rename, replace and link require arguments of the same type on Windows
 * readlink only supports unicode filenames on Windows
 * os.open() specifies the filename on OSError

Victor Stinner b024e84597 Issue #15478: Use path_error() in more posix functions, especially in Windows 
implementation

Victor Stinner 266f882dca Issue #15478: Fix compilation on Windows 2012-10-30 02:27:11 +01:00
Victor Stinner 292c835548 Issue #15478: Raising an OSError doesn't decode or encode the filename anymore 
Pass the original filename argument to OSError constructor, instead of trying
to encode it to or decode it from the filesystem encoding. This change avoids
an additionnal UnicodeDecodeError on Windows if the filename cannot be decoded
from the filesystem encoding (ANSI code page).

Victor Stinner 591c1cca32 Remove dead code 
os.urandom() has now one unique implementation, posix_urandom() which
calls _PyOS_URandom(). _PyOS_URandom() uses RAND_pseudo_bytes() on VMS.

Larry Hastings 9cf065cfdc Issue #14626: Large refactoring of functions / parameters in the os module. 
Many functions now support "dir_fd" and "follow_symlinks" parameters;
some also support accepting an open file descriptor in place of of a path
string.  Added os.support_* collections as LBYL helpers.  Removed many
functions only previously seen in 3.3 alpha releases (often starting with
"f" or "l", or ending with "at").  Originally suggested by Serhiy Storchaka;
implemented by Larry Hastings.

Changed shutil.copystat to use st_atime_ns and st_mtime_ns from os.stat
and ns= parameter to utime--it once again preserves exact metadata on Linux!

Charles-François Natali 7794090251 Following Nick's suggestion, rename posix.fdlistdir() to posix.flistdir(), to

Brian Curtin 569b494320 Fix #13327. utimensat now has the atime and mtime arguments set as optional,

it has a `flags` value at the end of the argument list (which
retains its 0 default).

Brian Curtin c8be84077b Correct completely broken os.stat behavior on Windows XP. 
After 1a3e8db28d49, Windows XP could not os.stat at all due to raising
immediately when GetFinalPathNameByHandle wasn't available (pre-Vista).
The proper behavior in that situation is to just not attempt a traversal
rather than outright rejecting.

This change additionally handles a failed malloc by setting the error code
and returning false.

Patch by Hirokazu Yamamoto.

Brian Curtin 3e86c99f90 Merge from 3.2 for Issue #12084. 2011-06-13 16:00:35 -05:00
Brian Curtin d25aef55c8 Fix #12084. os.stat on Windows wasn't working properly with relative symlinks. 
Use of DeviceIoControl to obtain the symlink path via the reparse tag was
removed. The code now uses GetFinalPathNameByHandle in the case of a
symbolic link and works properly given the added test which creates a symbolic
link and calls os.stat on it from multiple locations.

Victor Stinner also noticed an issue with os.lstat following the os.stat
code path when being passed bytes. The posix_lstat function was adjusted to
properly hook up win32_lstat instead of the previous STAT macro (win32_stat).

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 9a82eaade3 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.
