[Nice] Fwd: compatibility with rfc5766-turn-server

[Chunfeng Zhang]

Hi :
I have a question.
In agent.c, if we use full-mode, why nice always sends RFC3489 bind request
but not RFC5389 bind request?

static void
priv_add_new_candidate_discovery_stun (NiceAgent *agent,
    NiceSocket *socket, NiceAddress server,
    Stream *stream, guint component_id)
{
  CandidateDiscovery *cdisco;

  /* note: no need to check for redundant candidates, as this is
   *       done later on in the process */

  cdisco = g_slice_new0 (CandidateDiscovery);

  cdisco->type = NICE_CANDIDATE_TYPE_SERVER_REFLEXIVE;
  cdisco->nicesock = socket;
  cdisco->server = server;
  cdisco->stream = stream;
  cdisco->component = stream_find_component_by_id (stream, component_id);
  cdisco->agent = agent;
  *stun_agent_init (&cdisco->stun_agent, STUN_ALL_KNOWN_ATTRIBUTES,*
*      STUN_COMPATIBILITY_RFC3489,*
*      (agent->compatibility == NICE_COMPATIBILITY_OC2007 ||*
*       agent->compatibility == NICE_COMPATIBILITY_OC2007R2) ?*
*        STUN_AGENT_USAGE_NO_ALIGNED_ATTRIBUTES : 0);*

  nice_debug ("Agent %p : Adding new srv-rflx candidate discovery %p\n",
      agent, cdisco);

  agent->discovery_list = g_slist_append (agent->discovery_list, cdisco);
  ++agent->discovery_unsched_items;
}
