           Summary: Temp file layout tests fail on Linux
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: deanm at chromium.org

For example, these tests fail due to a platform difference in their use of the
builtin PHP sys_get_temp_dir.  See the comments at:

http://us.php.net/sys_get_temp_dir

"""This function does not always add trailing slash. This behaviour is
inconsistent across systems, so you have keep an eye on it."""

When running layout tests on Linux, sys_get_temp_dir does not return a trailing
slash.  We can see an example of the failure via strace:

[pid 13932] open("/tmppreflightCacheTimeout.txt",
O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)

The solution is just to always append a trailing slash, on some platforms this
might result in /tmp//blah, but that shouldn't be a problem.
