Hi all!
I am using PJSIP 1.4.5 on Symbian platform with the pjsua interface, and I also specify the nameservers for pjsua.
If I have outstanding nameserver queries, when I call pjsua_destroy(), a bit later I get an assertation in file
os_core_symbian.cpp, line 848. This is the pj_mutex_lock() function. The caller function was on_timeout() in resolver.c.
It was easy to figure out, that the assertation is because the querry timeout entry is not removed from the timer, I did the following modification in
in resolver.c line 355, pj_dns_resolver_destroy():
/*
* Notify pending queries if requested, and cancel timer entries
*/
it = pj_hash_first(resolver->hquerybyid, &it_buf);
while (it) {
pj_dns_async_query *q = (pj_dns_async_query *)
pj_hash_this(resolver->hquerybyid, it);
pj_dns_async_query *cq;
if (notify && q->cb) {
(*q->cb)(q->user_data, PJ_ECANCELLED, NULL);
}
pj_timer_heap_cancel( resolver->timer, &q->timer_entry );
cq = q->child_head.next;
while (cq != (pj_dns_async_query*)&q->child_head) {
if (notify && cq->cb) {
(*cq->cb)(cq->user_data, PJ_ECANCELLED, NULL);
}
pj_timer_heap_cancel( resolver->timer, &cq->timer_entry );
cq = cq->next;
}
it = pj_hash_next(resolver->hquerybyid, it);
}
As you can see I canceled the outstanding timer entries, if there are any.
I hope this helps.
Br,
Gabor
