           Summary: std.path.isabs broken for Windows
           Product: D
           Version: 1.030
          Platform: PC
               URL: http://www.digitalmars.com/d/1.0/phobos/std_path.html
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: darkuranium gmail.com


std.path.isabs(char[]) falsely reports paths as relative when they are, indeed,
absolute. For example:

isabs("/test") => 0 (should be 1)
isabs("\test") => 0 (should be 1)

Here is the program I used to test this -- see the comments in the source for
instructions (they are importaint):
http://paste.dprogramming.com/dpavbrtf

As you can see, although all paths are reported as relative, they are indeed
absolute.
This is visible by the fact that main.d cannot find test-rel which lies in the
same dir as the program itself.
It can, however find test-abs, which lies the root of the drive.

The drives are lacking. In Windows terminology, does a drive-less path still
qualify as absolute? (I looked around MSDN, couldn't find a good definition.)

It's tricky.  Windows accepts such paths, and they are absolute to the current
drive, but relative to the entire filesystem.  Since the same path (like
"\foo\bar\baz.txt") can refer to different files based on what the current
drive is set to, I guess it's still relative, in which case Phobos is right.

I'll close this considering that isabs is correct as is.
