From f4c21e89d7c6b578140e90c02b40eccb51ab8428 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Fri, 7 Sep 2012 00:41:03 +0200 Subject: [PATCH] real_path(): properly handle nonexistent top-level paths The change has two points: 1. Do not strip off a leading slash, because that erroneously turns an absolute path into a relative path. 2. Do not remove slashes from groups of multiple slashes; instead let chdir() handle them. It could be, for example, that it wants to leave leading double-slashes alone.
