assert_secure(path) click to toggle source

assert_secure checks that if a path exists it has minimally writable permissions. If not, it prints an error and exits. It only works on POSIX systems. Patches for other systems are welcome.

871:         abort "#{path} is insecure (#{'%o' % mode}). It may not be group or world writable. Exiting."
