Re: [SR-Users] simple test case: add user/delete user on kamailio 3.3 presence server
HI Since my previous email has attachment , it is still waiting for the approval. So here is again the text part ( please see the email below) According to the trace, here is the call flow for this case: 101(.224) --- proxy (.32) --- 103 (.1) 101/103 are jitsi 1.1 nightly build client, the configure is to use SIMPLE/xcap on clients. the call flow for 101 adding 103 as contact 101 proxy 103 | | | user-add-103 | | | | | | xcap put pres/rls | | |--------------------------> | | | | | | SUBSCRIBE (presence/103) | | |---------------------------> | | | 202 ok | | |<----------------------------| | | NOTIFY( presenc/pending) | | |<----------------------------| | | | NOTIFY ( winfo/101 pending) | | |---------------------------------->| | 200 ok | | |--------------------------> | | | | 200 OK | | |<----------------------------------| | | auth window pop | | user accept | | SUBSRIBE(presence/101) | | |<----------------------------------| | | 202 OK | | |---------------------------------->| | NOTIFY (winfo,103 active) | | |<-------------------------- | | | 200 ok | | |--------------------------> | | | | NOTIFY (presence/101) | | |---------------------------------> | | | 200 OK | | |<----------------------------------| | NOTIFY (presence/103 open) | | |<-------------------------- | | ****** ( missing part) | 200 ok | | |--------------------------> | | As on the 103, auth windows pop up, then click ok to accept (thus it will added 101 as contact), in this case it does not do any xcap operation? Is it the correct call flow? Thanks min On 06/19/2012 04:49 PM, Min Wang wrote:
Hi
Here is another similar case which does not work. maybe it is related the above issue as well.
Jitsi 1.1 client: 101/103 , with xcap as storage proxy: kamailio 3.3 ip network is: 192.168.122.0
the setup is like the following:
101(.224) --- proxy (.32) --- 103 (.1)
After all presence related db are truncated, kamailio was restart. then bring 101,103 online.
On 101 add 103, 103 prompt up authorization window, click ok. now on 103, I can see 101 online status
but on 101, I can not see 103 status <----the first trace file: the jitsi-101-add-103-confirm-2.pcap
(it is grey, even manually change 103 status from online to away etc, on 101, the 103 always showed grey. <--- second trace file: jitsi-101-103-change.pcap)
Please see the attached pcap files.
the watcher table shows:

Hello,
you have to share the content of the messages sent, providing just the url is not enough to see what happens.
watchers table is for the list of contacts and their global status in regard to presentity, active_watchers is for keeping the presence dialogs.
Cheers, Daniel

Hi
(1) I tested more. It is due to the difference between bria 3 and jitsi while handling the adding/removing contact:
if contact is added/removed:
for jitsi, it send out:
PUT /xcap-root/resource-lists/users/sip:101@192.168.122.32/index PUT /xcap-root/pres-rules/users/sip:101@192.168.122.32/presrules
for bria 3, it only send out
PUT /xcap-root/resource-lists/users/101@192.168.122.32/contacts-resource-list.xml HTTP/1.0. PUT /xcap-root/resource-lists/users/101@192.168.122.32/contacts-resource-list.xml
it does NOT send out the pres-rules.
Is it the good behavior ( from RFC point of view) ? should I call the pres_update_watchers even though its is for resource-lists?
(2) BTW, what is the exact purpose of watcher table?
e.g: on 101, if delete 103, watcher table become:
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 1 1340096051 2 sip:101@192.168.122.32 103 192.168.122.32 presence 3 terminated 1340096181
it is item 2 become terminated instead of item 1. If watcher table is for subscription, then seems item 1 should be terminated? Look at the code, it seems somehow serve as mixed role of subscription/auth/xcap purpose, not for subscription state?
and is the active_watcher mainly for the state machine of http://tools.ietf.org/html/rfc3857#section-4.7.1?
thanks.

then I deleted the 103 from the contact list, the watcher table still shows the same. For local storage, I'd expect an unsubscribe (subscribe with Expires=0) from 101 to 103. The obvious work-flow would be to set it to "terminated" in watchers table, and in case of a subsequent re-subscribe it should be changed back to "pending" state, although the state-machine doesn't indicate a transition from "terminated" back to "pending". Isn't this the case?
For xcap storage, there are other ways to block/remove a contact on/from the list. As Iñaki pointed out in http://lists.opensips.org/pipermail/devel/2009-August/003868.html, the xcap server needs to notify the sip server about the change, which in turn will notify the other party (103) that it's no longer allowed to see 101's state. If the xcap_server module of kamailio is used, there is the following code snippet in some examples floating around on the internet:
switch($rm) { case "PUT": xcaps_put("$var(uri)", "$hu", "$rb"); if($xcapuri(u=>auid)=~"pres-rules") { pres_update_watchers("$var(uri)", "presence"); pres_refresh_watchers("$var(uri)", "presence", 1); }
So, shouldn't this update the watchers accordingly? Anyways, also in this case the watcher state should change to "terminated", and in case of a re-subscribe it should go back to pending if xcap rules are allowing this.
Maybe someone with good xcap_server/presence insights could elaborate on that? to summarize, you say that when the contact is removed from the buddy list, the watcher table is not updated to state terminated by pres_update_watchers(...)?
