commit 530fac10aaef5e38327c8704d657a2e67987f102 Author: Roger Dingledine <arma@torproject.org> Date: Sun Sep 21 19:12:20 2014 -0400 Use optimistic data even if we don't know exitnode->rs I think we should know the routerstatus for our exit relay, since we built a circuit to it. So I think this is just a code simplication. --- src/or/circuituse.c | 32 ++++++++++++++++---------------- 1 file changed, 16 insertions(+), 16 deletions(-) diff --git a/src/or/circuituse.c b/src/or/circuituse.c index cb2d7e2..c1a8152 100644 --- a/src/or/circuituse.c +++ b/src/or/circuituse.c @@ -2070,7 +2070,7 @@ static void link_apconn_to_circ(entry_connection_t *apconn, origin_circuit_t *circ, crypt_path_t *cpath) { - const node_t *exitnode; + const node_t *exitnode = NULL; /* add it into the linked list of streams on this circuit */ log_debug(LD_APP|LD_CIRC, "attaching new conn to circ. n_circ_id %u.", @@ -2104,22 +2104,22 @@ link_apconn_to_circ(entry_connection_t *apconn, origin_circuit_t *circ, circ->isolation_any_streams_attached = 1; connection_edge_update_circuit_isolation(apconn, circ, 0); + /* Compute the exitnode if possible, for logging below */ + if (cpath->extend_info) + exitnode = node_get_by_id(cpath->extend_info->identity_digest); + /* See if we can use optimistic data on this circuit */ - if (cpath->extend_info && - (exitnode = node_get_by_id(cpath->extend_info->identity_digest)) && - exitnode->rs) { - /* Okay; we know what exit node this is. */ - if (optimistic_data_enabled() && - circ->base_.purpose == CIRCUIT_PURPOSE_C_GENERAL) - apconn->may_use_optimistic_data = 1; - else - apconn->may_use_optimistic_data = 0; - log_info(LD_APP, "Looks like completed circuit to %s %s allow " - "optimistic data for connection to %s", - safe_str_client(node_describe(exitnode)), - apconn->may_use_optimistic_data ?
