[sr-dev] new tmx function t_reuse_branch()

as per daniel's suggestion, i wrote a new tmx function t_reuse_branch(), which can currently be called from branch-failure route: /** * Creates new "main" branch by making copy of branch-failure branch. * Currently the following branch attributes are included: * request-uri, ruid, path, instance, and branch flags. */ static int w_t_reuse_branch(struct sip_msg* msg, char *p1, char *p2) { struct cell *t; int branch; if (msg == NULL) return -1; /* first get the transaction */ if (_tmx_tmb.t_check(msg, 0) == -1) return -1; if ((t = _tmx_tmb.t_gett()) == 0) { LM_ERR("no transaction\n"); return -1; } switch (get_route_type()) { case BRANCH_FAILURE_ROUTE: /* use the reason of the winning reply */ if ((branch = _tmx_tmb.t_get_picked_branch()) < 0) { LM_CRIT("no picked branch (%d) for a final response" " in MODE_ONFAILURE\n", branch); return -1; } rewrite_uri(msg, &(t->uac[branch].uri)); set_ruid(msg, &(t->uac[branch].ruid)); if (t->uac[branch].path.len) { set_path_vector(msg, &(t->uac[branch].path)); } else { reset_path_vector(msg); } setbflagsval(0, t->uac[branch].flags); set_instance(msg, &(t->uac[branch].instance)); return 1; default: LM_ERR("unsupported route_type %d\n", get_route_type()); return -1; } } the new "main" branch does not include destination uri and socket, because i didn't find them in struct ua_client. unless someone adds them to struct ua_clients, they thus need to be set separately from htable after calling t_reuse_branch(). is it ok that i commit the above function to tmx module? in addition, i would like to add $T_reply_bf (branch flags) pv, since i need to test some of the branch flags in other parts of branch-failure route. -- juha
