HI
I just did simple test-case: add user and delete user on kamailio 3.3
on 101 , I added 103, the watcher tables shows:
select * from watchers;
+----+------------------------+------------------+----------------+----------+--------+--------+---------------+
| id | presentity_uri | watcher_username | watcher_domain |
event | status | reason | inserted_time |
+----+------------------------+------------------+----------------+----------+--------+--------+---------------+
| 1 | sip:103@192.168.122.32 | 101 | 192.168.122.32 |
presence | 2 | | 1339772803 |
+----+------------------------+------------------+----------------+----------+--------+--------+---------------+
then I deleted the 103 from the contact list, the watcher table
still shows the same.
It seems a strange behavior, should this to be deleted from the db?
what's the expected behavior on the watchers table for delete/adding
user?
In my previos email testing case, there is terminated status=3 in
db, when will this item will be deleted?

From the http://tools.ietf.org/html/rfc3857#section-4.7.1, there is
nowhere to go if it it is in the terminated status.

just FYI, there were some discussions before regarding the deletion, state
machine.
