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

Hi Asgaroth, 

I'm using dmq and I haven't seen a msg get passed this:

    # Handles DMQ messages

    if (is_method("KDMQ")) {

        dmq_handle_message();

    }

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?

Joel.

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, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES

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