Comment:

 The addition of this check in `rend_cache_store_v2_desc_as_dir()` broke
 some unit tests:
 {{{
 +  if (!public_server_mode(options)) {
 +    log_warn(LD_BUG, "rend_cache_store_v2_desc_as_dir() called but we're
 "
 +             "not a public relay. Refusing.");
 +    return -1;
    }
 }}}

 My branch `ticket18332_028_01` fixes that in a "questionable ugly way". We
 could remove that check actually since it's made in the
 `directory_handle_command_post` prior to ever calling the store function
 and it's the only code path that goes into it.

 It also broke that test and I don't know why:

 {{{
 routerlist/pick_directory_server_impl: [forking]
   FAIL src/test/test_routerlist.c:328:
 assert(tor_memeq(rs->identity_digest, router3_id, DIGEST_LEN))
   [pick_directory_server_impl FAILED]
 }}}
