Bug #74997 for X11-Protocol: X11::Auth fails when XAUTHORITY is for "localhost" instead of correct hostname

Distribution: X11-Protocol-0.56 Perl version: v5.14.2 built for i586-linux-thread-multi Platform: openSUSE 12.1, 32-bit Linux kernel 3.2.4 The function X11::Auth->get_by_host() tries to find the X11 magic cookie for the host name returned by Sys::Hostname::hostname(), but if the file referenced by the XAUTHORITY variable contains "localhost" as the hostname instead of the real hostname, the for loop does not find the correct authentication token, and the function returns an empty list. Using "localhost" instead of the actual hostname is probably openSUSE-specific, and they store this hostname to use for X11 authentication in the environment variable called XAUTHLOCALHOSTNAME. However, using "localhost" in there is perfectly valid, I think. A longer discussion of the issue can be found in the Novell Bugzilla as bug #746894 [1], where a proposed patch is also attached. This patch contains two independent attempts to fix this issue, and I think that either of them should be enough; and the second part might be suitable for inclusion in the upstream X11:Auth Perl module.
