The os.utime() docs for Python 2 (http://docs.python.org/2/library/os.html#os.utime) and 3 (http://docs.python.org/3/library/os.html#os.utime) both contain the sentence
"Whether a directory can be given for path depends on whether the operating system implements directories as files (for example, *Windows does not*)"
"Windoes does not" is wrong. CPython 2.7 on Windows 7:
>>> os.utime(".", (100, 100))
>>> os.stat(".").st_mtime
100.0
We should
- either name a specific system for which this does not work
- or remove this example.
Windows XP and newer support this operation via SetFileTime (http://msdn.microsoft.com/en-us/library/windows/desktop/ms724933%28v=vs.85%29.aspx): "Sets the date and time that the specified file or directory was created, last accessed, or last modified."
I have grepped myself through a couple of CPython source trees and found
posixmodule.c: if (!SetFileTime(hFile, NULL, &atime, &mtime)
in 2.5, 2.6, 2.7. I guess the statement comes from 2.4 times, where `SetFileTime` only appears in `PC/bdist_wininst/extract.c`.
So, do we just remove the hint or does someone have an example at hand for which combination of Python and platform this does not work for directories? Once we have a decision, I will be happy to provide the mini patch. |
