Hi,

I can see that it works properly on kamailio v5.0.7, I've no instances of v5.1.x. It may just be related to master branch, however, in this instance I'm trying to use the presence dmq features that are in master at the moment. It might be that I pulled an in-flight bug on master, not sure.

That said, just to make sure it's not some work-in-progress happening on master branch, give it a try on latest stable release (v5.1.4) to see if you find the same behavior. I haven't tried on master but on v5.1.4 I'm not seeing that behavior.

Are you manually replicating stuff using dmq functions or are you taking advantage of auto-replication using modparam enable_dmq=1 on certain modules?

Hi All,

I've come across and oddity whereby my is_method("KDMQ") checks
are not matching.

I'm testing with kamailio master:

version: kamailio 5.2.0-dev6 (x86_64/linux) a16272
flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS,

poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
id: a16272
compiled on 15:27:21 Jul 31 2018 with gcc 7.3.1

Sample routing logic:

request_route {
    route("InitialMessageChecks");
    exit;
}


route[InitialMessageChecks] {
    xlog("L_INFO", "Received message type $rm from $si:$sp on
$Ri:$Rp");

    if ( is_method("KDMQ") ) { xlog("L_INFO", "KDMQ check passed."); }
    if ( is_method("OPTIONS") ) { xlog("L_INFO", "OPTIONS check
passed."); }
    if ( is_method("SUBSCRIBE") ) { xlog("L_INFO", "SUBSCRIBE
check passed."); }

}

In the logs I am only receiving the 1st log line in the initial
message checks route for message types of KDMQ, eg:

INFO: <script>: Received message KDMQ from 1.1.1.1:5060
<http://1.1.1.1:5060> on 1.1.1.2:5060 <http://1.1.1.2:5060>
INFO: <script>: Received message KDMQ from 1.1.1.3:5060
<http://1.1.1.3:5060> on 1.1.1.2:5060 <http://1.1.1.2:5060>

I never seem to hit the is_method check log line when the method
type is KDMQ.

I do see the options/subscribe logs though:

INFO: <script>: OPTIONS check passed.
INFO: <script>: SUBSCRIBE check passed.

nothing for KDMQ.

Reason for asking is: this check never matches and breaks the dmq bus:

if ( is_method("KDMQ") ) {
    if ( dmq_is_from_node() ) {
        dmq_handle_message();
        exit;
    } else {
        exit;
    }
}

Any thoughts, or am I going crazy :)

Thanks

Hi,

This should fix:

https://github.com/kamailio/kamailio/pull/1611

Please confirm either way.

Cheers,

Charles

Hello,

I have checked and it is a problem with is_method() not matching "KDMQ" (there is no method definition to match when parsing the message first line). This is not a DMQ issue specifically, and 'if (method == "KDMQ")' works just fine. I'm sure it _used_ to work (in fact, it's documented!) - although I may be totally mistaken, since everywhere we use ‘method’.

I will try to see later if something changed anywhere in textops or core, but in the meantime I suggest using ‘method’ for now.

Cheers,

Charles
