A couple of lines down it says: "The pointer returned by readdir() points to data which may be overwritten by another call to readdir() on the same directory stream. This data is not overwritten by another call to readdir() on a different directory stream."
This explicitly says that implementations cannot use a static dirent structure.
Ah, right. I read over this several times, and still managed to miss that point. Thanks.
Of course, the most natural implementation associates the storage for the result with the DIR*, so it's probably not a real problem...
If this were a problem on some platform I'd expect it to be so ancient that it doesn't offer readdir_r either.
Sure - I would have just removed Py_BEGIN_ALLOW_THREADS on systems which don't have readdir_r. But this is now unnecessary. Regards, Martin
