From f53f4da9c68941fe70a3ca9e3fc792c8acf69c0c Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 8 May 2012 16:51:47 +0200 Subject: [PATCH] block: simplify path_is_absolute On Windows, all the logic is already in is_windows_drive and is_windows_drive_prefix. On POSIX, there is no need to look out for colons. The win32 code changes the behaviour in some cases, we could have something like "d:foo.img". The old code would treat it as relative path, the new one as absolute. Now the path is absolute, because to go from c:/program files/blah to d:foo.img you cannot say c:/program files/blah/d:foo.img. You have to say d:foo.img. But you could also say it's relative because (I think, at least it was like that in DOS 15 years ago) d:foo.img is relative to the current path of drive D. Considering how path_is_absolute is used by path_combine, I think it's better to treat it as absolute.
