-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Sjors Gielen on 1/25/2009 6:46 AM: > Hey all, > > In Cygwin (the CVS version), it seems paths starting with two slashes > are "special paths" for accessing remote machines or bypassing the mount > table. > > This however is incompatible with Linux, where i.e. //etc is a valid > path. See, for example: (`ls` indicators removed for readability) Not only is it perfectly compatible with Linux, but it is allowed by POSIX. This is a design decision that all portable programs must be aware of - you cannot blindly use '//' to mean '/', and not just because of cygwin. http://www.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_266 http://www.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12 "A pathname that begins with two successive <slash> characters may be interpreted in an implementation-defined manner, although more than two leading <slash> characters shall be treated as a single <slash> character." > > Therefore, I'm suggesting to remove "//" as a > special path from conv_to_win32_path. Won't happen. We've intentionally defined it as a synonym for Windows \\server\share notation. - -- Don't work too hard, make some time for fun as well!
