[Python-Dev] Special file "nul" in Windows and os.stat (original) (raw)

In order to keep the higher accuracy timestamps for normal files and to maintain the old behavior, my recommendation would be that the existing implementation of win32stat/win32wstat be extended to use FindFileFirst if GetFileAttributes* fails. I would be willing to do the legwork for such a patch if everyone agrees this is the appropriate solution.

That, in general, might be wrong. os.stat("*.txt") should fail, even though FindFirstFile will succeed when passed that string.

That was my primary motivation for not using FindFirstFile by default: it may succeed even if the string being passed does not denote a file name.

* As an aside, Martin, I find the argument that "hard-wiring is bad" to be against what is actually occurring in the posixmodule. For that matter, the SIFEXEC flag is hardwired to path in (*.bat, *.cmd, *.exe, *.com) despite the fact that the platform says it is really anything in the list of os.getenv('PATHEXT'), but I suppose that is a bug for another day.

No. See the source of the C library - the algorithm Python uses now is (or should be) the same as the one of the C library. Of course, you may argue that then msvcrt has the same bug.
