In case you missed it, I implemented _Py_CreateFile2() in bpo-46506 and rewrote
os.stat() based on it. Check it out in case you're interested in moving forward
with a PR in bpo-46506.
For this issue, follow_symlinks is fairly simple to support with
_Py_CreateFile2(). We may as well add fd support, since that's trivial to add.
For example:
if (path->fd != -1) {
hFile = _Py_get_osfhandle(path->fd);
} else {
Py_BEGIN_ALLOW_THREADS
hFile = _Py_CreateFile2(path->wide, FILE_WRITE_ATTRIBUTES, 0,
OPEN_EXISTING, NULL, follow_symlinks, NULL);
Py_END_ALLOW_THREADS
}
if (hFile == INVALID_HANDLE_VALUE) {
if (path->fd == -1) {
path_error(path);
}
return NULL;
}
One also has to define the following macros to declare follow_symlinks and fd
support: UTIME_HAVE_NOFOLLOW_SYMLINKS and PATH_UTIME_HAVE_FD.
To announce support in os.supports_follow_symlinks and os.supports_fd, it
should be conditioned on MS_WINDOWS, i.e. _add("MS_WINDOWS", "utime"). The os
module is frozen, so changing these two sets requires rebuilding Python.
