To get the branch attributes, the code should be
similar to execution of
failure_route. In failure_route, the attributes are taken from winning
branch. In branch-failure, the attributes should be taken from current
branch. But in both cases is dealing with a branch structure.
the code in t_reply.c for branch failure handling already looks very
similar to failure handling. run_failure_handlers() use branch
on_failure = t->uac[picked_branch].on_failure;
whereas run_branch_failure_handlers() use branch
on_branch_failure = t->uac[picked_branch].on_branch_failure;
then both create faked request environment, run the route handler, and
restore the original environment.
why the faked request in case of branch failure does not include correct
$ru goes beyond my knowledge of tm module.
