Hi Daniel,
I was wondering, did you find some way in which this was causing the issue?
Theoretically, if the module is loaded successfully then peer_list cannot
be null...
(dmq.c)
static int mod_init(void)
{
...
/* load peer list - the list containing the module callbacks for
dmq */
peer_list = init_peer_list();
if(peer_list==NULL) {
LM_ERR("cannot initialize peer list\n");
return -1;
}
...
Also, peer_list should always contain the local notification peer, added
during startup and prior to run_init_callbacks() ever being called:
...
/**
* add the dmq notification peer.
* the dmq is a peer itself so that it can receive node
notifications
*/
if(add_notification_peer()<0) {
LM_ERR("cannot add notification peer\n");
return -1;
}
...
Am I missing something obvious?
Best,
Charles

dmq: safety check for peer_list when calling the callbacks
- can result in crashing if it is not set
