48 // Notes for Windows path impl:
49 // The MAX_PATH is 260, but 253 is the practical limit due to some API bugs
50 // See http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247.aspx for good information
51 // about windows paths.
52 // That same page puts a bunch of restrictions on allowed characters in a path.
53 // `\foo.txt` means "relative to current drive", but will not be considered to be absolute here
54 // as `∃P | P.join("\foo.txt") != "\foo.txt"`.
55 // `C:` is interesting, that means "the current directory on drive C".
56 // Long absolute paths need to have \\?\ prefix (or, for UNC, \\?\UNC\). I think that can be
57 // ignored for now, though, and only added in a hypothetical .to_pwstr() function.
58 // However, if a path is parsed that has \\?\, this needs to be preserved as it disables the
59 // processing of "." and ".." components and / as a separator.
60 // Experimentally, \\?\foo is not the same thing as \foo.
61 // Also, \\foo is not valid either (certainly not equivalent to \foo).
62 // Similarly, C:\\Users is not equivalent to C:\Users, although C:\Users\\foo is equivalent
63 // to C:\Users\foo. In fact the command prompt treats C:\\foo\bar as UNC path. But it might be
64 // best to just ignore that and normalize it to C:\foo\bar.
66 // Based on all this, I think the right approach is to do the following:
67 // * Require valid utf-8 paths. Windows API may use WCHARs, but we don't, and utf-8 is convertible
68 // to UTF-16 anyway (though does Windows use UTF-16 or UCS-2? Not sure).
69 // * Parse the prefixes \\?\UNC\, \\?\, and \\.\ explicitly.
70 // * If \\?\UNC\, treat following two path components as server\share. Don't error for missing
72 // * If \\?\, parse disk from following component, if present. Don't error for missing disk.
73 // * If \\.\, treat rest of path as just regular components. I don't know how . and .. are handled
74 // here, they probably aren't, but I'm not going to worry about that.
75 // * Else if starts with \\, treat following two components as server\share. Don't error for missing
77 // * Otherwise, attempt to parse drive from start of path.
79 // The only error condition imposed here is valid utf-8. All other invalid paths are simply
80 // preserved by the data structure; let the Windows API error out on them.
