We noticed during porting that mod _webdav gave an invalid response on PROPFIND request at depth one where the dav:response entry containing the properties for the target resource was missing.

Looking at the code, mod_webdav assumes that while iterating over the entries in the target collection using readdir(), there should be a dot entry to get properties for the target resource. If the usage of readdir should be POSIX compatible I belive this assumption is a bit to strict. According to IEEE Std 1003.1 2004.

"If entries for dot or dot-dot exist, one entry shall be returned for dot and one entry shall be returned for dot-dot; otherwise, they shall not be returned."

This has also been noted for the GNU C library.

"Portability Note: On some systems readdir may not return entries for . and .., even though these are always valid file names in any directory. See File Name Resolution."

To remain compatible it would be nice to have this assumption removed
