Comment (by nickm):

 It looks like you're getting an error in travis CI:

 {{{
 src/test/test_dirvote.c:38:14: error: no previous extern declaration for
 non-static variable 'router_properties' [-Werror,-Wmissing-variable-
 declarations]

 digestmap_t *router_properties = NULL;
 }}}

 This error means that the compiler wants you either to declare
 `router_properties` as static, to make it clear that it can only be used
 inside of `test_dirvote.c`, or instead to make an extern declaration for
 `router_properties` in some header, to make it clear that other modules
 can use it too.

 Now I'm looking over the patch...
