[Serusers] Turn off forking in SER?

[Vitaly Nikolaev]

Not as far as I know. I realized serial forking by sequence of
failure_routes and exec_dset

Like:

 

route[1]{

        xlog("L_ALERT", "\n(%ci:%is) entering route[1] (%ru)\n");

        if ((isflagset(5)) || (isflagset(6))) {

                xlog("L_ALERT", "\n(%ci:%is) (rt1) at least one of the
participants is NATed->record_route\n");

                xlog("L_ALERT", "\n(%ci:%is) (rt1) -->setting up reply
processing ->onreply_route[1]");

                t_on_reply("1");

                if (method=="INVITE") {

                        xlog("L_ALERT", "\n(%ci:%is) (rt1) INVITE
request-->force_rtp_proxy, set NATED-INVITE flag(7)");

                        force_rtp_proxy();

                        append_hf("P-hint: rt1, request forced to rtp
proxy\r\n");

                        setflag(7);

                };

        };

 

        consume_credentials();

        if(method=="INVITE") {

                t_on_reply("1");

                t_on_failure("1");

        }

        record_route();

        consume_credentials();

 

        xlog("L_ALERT", "\n(%ci:%is) (rt1) relaying message ... (%tu)");

        if (!t_relay()) {

                log(1, "(rt1) t_relay error occured\n");

                sl_reply_error();

        };

}

 

onreply_route[1] {

        xlog("L_ALERT", "\n(%ci:%is) onreply_route[1] entered\n");

 

        if ((isflagset(5)) || (isflagset(6))) {

                xlog("L_ALERT", "\n(%ci:%is) (or1) transaction was sent
to a NATED client -> fix nated contact\n");

                fix_nated_contact();

                append_hf("P-hint: or1, fixed NAT contact for
response\r\n");

        }

 

        if ( (status=~"100") ) {

                xlog("L_ALERT", "\n(%ci:%is) (or1) status 100
received\n");

        };

 

        if ( (status=~"180") ) {

                xlog("L_ALERT", "\n(%ci:%is) (or1) status 180
received\n");

        };

 

        if ( (status=~"202") ) {

                xlog("L_ALERT", "\n(%ci:%is) (or1) status 202
received\n");

        };

 

        if ( (status=~"200" || status=~"183") ) {

                xlog("L_ALERT", "\n(%ci:%is) (or1) status 2xx or 183");

                if ( isflagset(7) ) {

                        xlog("L_ALERT", "\n(%ci:%is) (or1) marked(7) as
NATED-INVITE -> force_rtp_proxy \n");

                        force_rtp_proxy();

                        append_hf("P-hint: or1, response forced to rtp
proxy\r\n");

                };

        };

}      

 

failure_route[1] {

        xlog("L_ALERT", "\n(%ci:%is) failureroute[1] entered\");

        exec_dset("/usr/local/ser/bin/getroute_a 3");

        if (uri=~"sip:[loop|stop]@sip.frontlineglobal.net") {

              xlog("L_ALERT", "\n(%ci:%is) STOP DETECTED");

              break;

        }

        t_on_failure("2");

        t_on_reply("1");

        xlog("L_ALERT", "\n(%ci:%is) (fr1) relaying message ...(%tu)");

        append_branch();

        if (!t_relay()) {

                xlog("L_ALERT", "\n(%ci:%is) (fr1) t_relay error
occured\n");

        };

}

failure_route[2] {

        xlog("L_ALERT", "\n(%ci:%is) failureroute[2] entered\");

        exec_dset("/usr/local/ser/bin/getroute_a 3");

        if (uri=~"sip:[loop|stop]@sip.frontlineglobal.net") {

              xlog("L_ALERT", "\n(%ci:%is) STOP DETECTED");

              break;

        }

        t_on_failure("3");

        t_on_reply("1");

        xlog("L_ALERT", "\n(%ci:%is) (fr2) relaying message ...(%tu)");

        append_branch();

        if (!t_relay()) {

                xlog("L_ALERT", "\n(%ci:%is) (fr2) t_relay error
occured\n");

        };

}

 

... etc

 

 

So far it doing what I want :-)

 

And this is kind of combination paraller and serial forking 

 

Btw, serial is not really forking.. this is more steps.. or I
misunderstand your question ?

Is it possible, with the present implementation of SER, by means only of
the ser.cfg file, to get SER to use serial forking in place of parallel
forking?  

thanks,
bert
