Summary: Bug in presence when using fallback2db
Initial Comment:
Hi,
While using the presence module, I run this scenario:
a. user1 SUBSCRIBE's to presence of user2
(subscription is now pending)
b. user2 allows user1 in pres-rules
(refreshWatchers is called, subscription is now active. user1 receives a NOTIFY
from presence server with user2's current tuple and Subscription-State: active)
c. user2 PUBLISH'es a new presence tuple
-- at this point presence server should NOTIFY user1 of the new presence but it
doesn't (that's the bug).
My modparams:
modparam("presence|presence_xml", "db_url", "mysql://r...@localhost/opensips")
modparam("presence", "server_address", "sip:presence.example.com:10500")
modparam("presence", "fallback2db", 1)
modparam("presence", "clean_period", 30)
What I see in the debug trace is that get_subs_dialog (from notify.c) can't
find any dialogs in the database, and all those in the subs hash are flagged
NO_UPDATEDB_FLAG. This is probably what's causing the problem.
Strangely, in the above scenario if user1 un-SUBSCRIBEs and re-SUBSCRIBEs to
user2's presence - it does receive notifications.
Regards,
Oren K.

Hi Anca,
I've attached a debug-log and wireshark pcap file to the post. The pcap
file also contains the XCAP PUTs to change the presence rules. The only
error in the log comes from presence_xml not being able to extract a tuple
node because our client uses <pdm:person> for the presence (Same bug
happened to us when we tried with <tuple> so that's not the issue). The
things that strike me odd in presence_bug.log are:
(after step b. user2 allows user1 in pres-rules)
line 634: DBG:presence:update_pw_dialogs: found 1 matching dialogs
the module finds the watcher dialog and updates it due to refreshWatchers.
user1 receives a NOTIFY with Subscription-State:active. Now step c. user2
PUBLISH'es a new presence tuple:
line 919: DBG:core:parse_msg: method: <PUBLISH>
everything looks okay BUT:
line 1087: DBG:presence:get_subs_db: The query for subscribtion for [uri]=
sip:us...@openims.summit-tech.ca for [event]= presence returned no result
line 1110: DBG:presence:get_subs_dialog: s->db_flag== UPDATEDB_FLAG
line 1111: DBG:presence:get_subs_dialog: found 0 dialogs( 0 in database
and 0 in hash_table)
line 1112: DBG:presence:publ_notify: Could not find subs_dialog
..suddenly there are no subscribers?
Thanks.

Hi Oren,
I have just downloaded myself the release and tested and the scenario that
you described works.
Do you notice any error in your log file?
regards,
Anca
