[sr-dev] [LCR] next_gw() doesn't update $ru

[Iñaki Baz Castillo]

Hi, in failure route I call next_gw(), it success and the request is
sent to a second gateway (inspecting with ngrep I see that the sent
request has the gw IP as RURI).
But if I print (xlog) $ru it still shows the previously selected gw
(the first one).

This is, the behaviour is correct but $ru is not updated in the script process.

I show an example which hopefully would show the issue (xlogs).
Basically the script invokes ROUTE_GW which uses LCR to select the
first gw, sets FAILURE_ROUTE_GW and calls ROUTE_DEFAULT (in which
t_relay is done). FAILURE_ROUTE block also sets FAILURE_ROUTE block,
uses LCR to select a new gw and calls to ROUTE_DEFAULT:
