Hi all, I've made a clean installation of kamailio 3.2.0 from 'http://deb.kamailio.org/kamailio32 squeeze main' repository, on a squeeze debian machine (2.6.32-5-686).

Installed also kamailio-presence-modules, same version.

I'm just using the default kamailio.cfg that comes with the package, with these minimal additions:

loadmodule "db_text.so" loadmodule "pua.so" loadmodule "pua_usrloc.so"

...

modparam("pua", "db_url", "text:///usr/share/kamailio/dbtext/kamailio") modparam("pua_usrloc", "default_domain", "192.168.142.130")

Inside the registration management logic I've added pua_set_publish() right before saving the location:

route[REGISTRAR] { if (is_method("REGISTER")) { ... pua_set_publish();

if (!save("location")) sl_reply_error();

exit; } }

When I first register (XLite 4.1 for Windows), pua_usrloc correctly gets the callback and is able to generate a PUBLISH request through pua.

But when there's an un-registration, or when the contact expires, even if the callbacks are correctly fired, the PUBLISH (which I'd expect with status 'closed') is not generated.

...

From the logs (debug level 4), an un-registration:

8(7652) DEBUG: usrloc [ul_callback.h:89]: contact=0xb50ae7cc, callback type 4/4, id 3 entered 8(7652) DEBUG: pua_usrloc [ul_publish.c:216]:DELETE type 8(7652) DEBUG: pua_usrloc [ul_publish.c:255]: uri= sip:20701090@192.168.142.130 8(7652) DEBUG: pua_usrloc [ul_publish.c:66]: publ: 8(7652) DEBUG: pua_usrloc [ul_publish.c:67]: uri= sip:20701090@192.168.142.130 8(7652) DEBUG: pua_usrloc [ul_publish.c:68]: id=UL_PUBLISH.NmY5Zjc2YjcwNzEwNTk4YTY1NzA2Y2Y0MWQyMGRhOGY. 8(7652) DEBUG: pua_usrloc [ul_publish.c:69]: expires= 0 8(7652) DEBUG: pua [send_publish.c:403]: pres_uri=sip:20701090@192.168.142.130 8(7652) DEBUG: pua [hash.c:121]: core_hash= 444 8(7652) DEBUG: pua [hash.c:174]: record not found 8(7652) DEBUG: pua [send_publish.c:444]: insert type 8(7652) DEBUG: pua [send_publish.c:448]: UPDATE_TYPE and no record found 8(7652) DEBUG: pua [send_publish.c:454]: request for a publish with expires 0 and no record found 8(7652) DEBUG: sl [sl.c:278]: reply in stateless mode (sl)

As an additional information, the pua table in /usr/share/kamailio/dbtext/kamailio/pua has not been populated.

The AOR was correctly displayed with 'ul show' while the registration was valid.

Any suggestion on what am I be doing wrong? Would it be worth testing the same scenario using mysql as DB?

Thanks in advance for your time.

can you switch to nightly builds from branch 3.2 just to be sure it is not related to something that was fixed since 3.2.0 was released? The repo are listed at:

http://www.kamailio.org/wiki/packages/debs#kamailio_32_-_nightly_builds

db_text is not really suitable for dealing with large data and write to disk when the sip server is shut down, maybe it is better to use db_sqlite for this case, at least you can check the content of the db table with sqlite tools.

Thanks Daniel,

I've switched and now have installed 3.2.1, and moved to sqlite too. I've spent some time to verify a change in behaviour, but I'm observing the same. Registering with a different device (e.g. sipp) gives the same result.

...

db_text is not really suitable for dealing with large data and write to disk when the sip server is shut down, maybe it is better to use db_sqlite for this case, at least you can check the content of the db table with sqlite tools.

My current goal is a proof of concept so I'm not concerned about performances - am I right in thinking that the problem in finding the presentity in pua's hash table is independent from the DB usage, or may it have an impact?

Cheers, Giacomo

Registering with a different device (e.g. sipp) gives the same result.

I tested with default config, where I enabled mysql and presence service, plus loaded and configured pua and pua_usrloc similar to your snippet. All seemed ok, I pasted the ngrep to the end of my reply, first for register and then for un-register.

In your case, is the publish for registration getting 200ok?

Well, the issue of using db_text might be with storing the xml documents (publish body) in presence table. db_text keeps a raw per line in a text file.

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Hi Daniel, Thanks for your feedback. Yes, using mysql and enabling presence made it work for un-registrations too. Just for the purpose of this scenario I'm sending the PUBLISH back to the same entity, and it's being handled as a presentity.

I still have a missing piece though (which is in fact the reason for this configuration): having PUBLISH requests triggered by the expiration of a contact.

When a contact expires, pua_usrloc is now logging:

Jan 19 10:12:03 debian6 /usr/sbin/kamailio[4359]: INFO: pua_usrloc [ul_publish.c:211]: should not send ul publish

(please see below for traces and details).

Since I'm marking a registration with pua_set_publish(), why is that flag not seen as true when usrloc fires an EXPIRE callback?

I've tried marking every REGISTER request with pua_set_publish(), and not just the first one, before calling save("location") but the result was the same.

Thanks again, Giacomo

can you switch to nightly builds from branch 3.2 just to be sure it is not related to something that was fixed since 3.2.0 was released?

In your case, is the publish for registration getting 200ok?

...

db_text is not really suitable for dealing with large data and write to disk when the sip server is shut down, maybe it is better to use db_sqlite for this case, at least you can check the content of the db table with sqlite tools.

Well, the issue of using db_text might be with storing the xml documents (publish body) in presence table. db_text keeps a raw per line in a text file.

Cheers, Daniel

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Hello,

Hi Daniel,

Thanks for your feedback. Yes, using mysql and enabling presence made it work for un-registrations too.

Just for the purpose of this scenario I'm sending the PUBLISH back to the same entity, and it's being handled as a presentity.

I still have a missing piece though (which is in fact the reason for this configuration): having PUBLISH requests triggered by the expiration of a contact.

When a contact expires, pua_usrloc is now logging:

Jan 19 10:12:03 debian6 /usr/sbin/kamailio[4359]: INFO: pua_usrloc [ul_publish.c:211]: should not send ul publish

(please see below for traces and details).

Since I'm marking a registration with pua_set_publish(), why is that flag not seen as true when usrloc fires an EXPIRE callback?

I've tried marking every REGISTER request with pua_set_publish(), and not just the first one, before calling save("location") but the result was the same.

the PUBLISH for registration expiration does not make sense, as PUBLISH has also an expire interval, so the record in the presence server should expire at the same time. A publish with update state to close will eventually hit the presence server when there is no record for it. Presence server will send notifications when the record in its table expires.

Cheers, Daniel

Thanks again,

Giacomo

Thanks Daniel,

can you switch to nightly builds from branch 3.2 just to be sure it

is not related to something that was fixed since 3.2.0 was released?

I've switched and now have installed 3.2.1, and moved to sqlite too.

I've spent some time to verify a change in behaviour, but I'm observing the same.

Registering with a different device (e.g. sipp) gives the same result.

I tested with default config, where I enabled mysql and presence service, plus loaded and configured pua and pua_usrloc similar to your snippet. All seemed ok, I pasted the ngrep to the end of my reply, first for register and then for un-register.

In your case, is the publish for registration getting 200ok?

...
db_text is not really suitable for dealing with large data and write

to disk when the sip server is shut down, maybe it is better to use db_sqlite for this case, at least you can check the content of the db table with sqlite tools.

My current goal is a proof of concept so I'm not concerned about performances -- am I right in thinking that the problem in finding the presentity in pua's hash table is independent from the DB usage, or may it have an impact?

Well, the issue of using db_text might be with storing the xml documents (publish body) in presence table. db_text keeps a raw per line in a text file.

Cheers, Daniel

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Ah thanks Daniel, So I had a wrong expectation on the behaviour of pua_usrloc. It does make sense that the PUBLISH already carries its expiry and so the expiration moment is implicit and should/can be handled elsewhere.

I think what confused me were two things: the pua_usrloc documentation and the fact that pua_usrloc does register for EXPIRE callbacks with usrloc.

I'm referring to: "The pua_usrloc module is the connector between the usrloc and pua modules. It creates the environment to send PUBLISH requests for user location records, on specific events (e.g., when new record is added in usrloc, a PUBLISH with status open (online) is issued; when expires, it sends closed (offline))."

Thanks for clarifying this.

Regards, Giacomo

Hello,

On 1/19/12 11:22 AM, Giacomo Vacca wrote: Hi Daniel, Thanks for your feedback. Yes, using mysql and enabling presence made it work for un-registrations too. Just for the purpose of this scenario I'm sending the PUBLISH back to the same entity, and it's being handled as a presentity.

I still have a missing piece though (which is in fact the reason for this configuration): having PUBLISH requests triggered by the expiration of a contact.

When a contact expires, pua_usrloc is now logging:

Jan 19 10:12:03 debian6 /usr/sbin/kamailio[4359]: INFO: pua_usrloc [ul_publish.c:211]: should not send ul publish

(please see below for traces and details).

Since I'm marking a registration with pua_set_publish(), why is that flag not seen as true when usrloc fires an EXPIRE callback?

I've tried marking every REGISTER request with pua_set_publish(), and not just the first one, before calling save("location") but the result was the same.

Cheers, Daniel

Thanks again, Giacomo

can you switch to nightly builds from branch 3.2 just to be sure it is not related to something that was fixed since 3.2.0 was released?

In your case, is the publish for registration getting 200ok?

db_text is not really suitable for dealing with large data and write to disk when the sip server is shut down, maybe it is better to use db_sqlite for this case, at least you can check the content of the db table with sqlite tools.

Well, the issue of using db_text might be with storing the xml documents (publish body) in presence table. db_text keeps a raw per line in a text file.

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Hi Giacomo,

On 1/19/12 11:49 AM, Giacomo Vacca wrote:

...

Ah thanks Daniel,

So I had a wrong expectation on the behaviour of pua_usrloc.

It does make sense that the PUBLISH already carries its expiry and so the expiration moment is implicit and should/can be handled elsewhere.

I think what confused me were two things: the pua_usrloc documentation and the fact that pua_usrloc does register for EXPIRE callbacks with usrloc.

I'm referring to:

"The pua_usrloc module is the connector between the usrloc and pua modules. It creates the environment to send PUBLISH requests for user location records, on specific events (e.g., when new record is added in usrloc, a PUBLISH with status open (online) is issued; when expires, it sends closed (offline))."

perhaps the documentation is misleading a bit with its phrasing. It send offline (closed) when it is an un-register, before the expiration. I haven't looked in the code, but based on log messages and correlated with the expired carried by PUBLISH, the behavior is correct over all.

There is another aspect, usrloc cleans up expired records on timer, so usrloc callback can be executed later than actual expiration. A publish at that time could be late. Of course, presence does cleanup on timer as well, but it may be more accurate to handle expiration there. It is like when an UA with presence support disappears from networks, without sending any PUBLISH updates.

Cheers, DAniel

Hi Daniel,

Thanks for your feedback. Yes, using mysql and enabling presence made it work for un-registrations too.

Just for the purpose of this scenario I'm sending the PUBLISH back to the same entity, and it's being handled as a presentity.

I still have a missing piece though (which is in fact the reason for this configuration): having PUBLISH requests triggered by the expiration of a contact.

When a contact expires, pua_usrloc is now logging:

Jan 19 10:12:03 debian6 /usr/sbin/kamailio[4359]: INFO: pua_usrloc [ul_publish.c:211]: should not send ul publish

(please see below for traces and details).

Since I'm marking a registration with pua_set_publish(), why is that flag not seen as true when usrloc fires an EXPIRE callback?

I've tried marking every REGISTER request with pua_set_publish(), and not just the first one, before calling save("location") but the result was the same.

the PUBLISH for registration expiration does not make sense, as PUBLISH has also an expire interval, so the record in the presence server should expire at the same time. A publish with update state to close will eventually hit the presence server when there is no record for it. Presence server will send notifications when the record in its table expires.

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Thanks Daniel. What I'd like to achieve is this: given a cluster of kamailio-based proxy/registrar, notify a separate entity whenever a contact is inserted or removed (either by deletion or expiration).

I'd like this separate entity to be stateless (i.e. don't manage expiry time), avoid using a DB as shared information and have asynchronous notifications.

This is why I thought pua_usrloc could help me, without the need of a full presence server in the architecture to manage expiry times for presentities.

What do you think could be used to achieve this?

...

From my point of view the ideal solution is implementing reg-info events (RFC 3680), where the separate entity mentioned above acts as watcher for reg-info events on all kamailio instances.

But I'm really looking at a simpler, lighter solution.

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

Hi Giacomo,

I patched few days ago to make pua_usrloc sending the PUBLISH also for location record expiration.

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=bdbacf55... http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=266fa4e2...

The idea is to set a branch flag for marking the contact for publishing -- pua_set_publish() can be still used actually, it sets also the branch flag internally, if the module parameter specifying the flag is set -- alternative is to use directly setbflag(index).

I was out of office and couldn't try it yet, maybe you can test and report if it is working fine.

You have to install devel version, either from git or from nightly debs:

I'd like this separate entity to be stateless (i.e. don't manage expiry time), avoid using a DB as shared information and have asynchronous notifications.

This is why I thought pua_usrloc could help me, without the need of a full presence server in the architecture to manage expiry times for presentities.

What do you think could be used to achieve this?

From my point of view the ideal solution is implementing reg-info events (RFC 3680), where the separate entity mentioned above acts as watcher for reg-info events on all kamailio instances.

But I'm really looking at a simpler, lighter solution.

Hi Giacomo,

I think what confused me were two things: the pua_usrloc documentation and the fact that pua_usrloc does register for EXPIRE callbacks with usrloc.

Cheers, DAniel

Hello,

I still have a missing piece though (which is in fact the reason for this configuration): having PUBLISH requests triggered by the expiration of a contact.

When a contact expires, pua_usrloc is now logging:

Jan 19 10:12:03 debian6 /usr/sbin/kamailio[4359]: INFO: pua_usrloc [ul_publish.c:211]: should not send ul publish

(please see below for traces and details).

Since I'm marking a registration with pua_set_publish(), why is that flag not seen as true when usrloc fires an EXPIRE callback?

I've tried marking every REGISTER request with pua_set_publish(), and not just the first one, before calling save("location") but the result was the same.

Cheers, Daniel

New subject: pua_usrloc, PUBLISH not send when contact is deleted or expires

As promised test results for pua_usrloc: it's working correctly (devel version from git, Linux debian 2.6.32-5-686). Please see below traces and logs extracts (just for the purpose of the test the PUBLISH is sent to localhost as configured).

Module configuration was:

modparam("pua", "db_url", DBURL); # mysql modparam("pua_usrloc", "default_domain", "127.0.0.1") modparam("pua_usrloc", "branch_flag", 9)

Just for completeness I've verified that pua_usrloc keeps working OK for contact deletes.

Thanks! Giacomo ---

Hi Giacomo,

I patched few days ago to make pua_usrloc sending the PUBLISH also for location record expiration.

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=bdbacf55... http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=266fa4e2...

I was out of office and couldn't try it yet, maybe you can test and report if it is working fine.

You have to install devel version, either from git or from nightly debs:
