Summary:ASTERISK-09843: Incorrect notify handling when hints contain multiple devices

Description:There's a logic flaw in transmit_state_notify():

When sending a state notification, the hints for the extension are checked to see if the device is offline; if so it overrides the state notification to say "not online".

The problem: if your hint contains multiple devices, _any_ of these being offline will override the state. The state should only be overridden if _all_ the hinted devices are offline.

This breaks BLFs for Polycom devices (and anything else using pidf/xpidf notifications) when you have multiple devices hinted.

This was introduced by the fix for ASTERISK-9259.


Patch attached.

Well, ok - patch _would_ be attached, but it's asking me to sign the license agreement. There is already one on file under Vadacom Ltd. Signing again requires going through all the corporate procedures, at which point your name will be mud with my CEO - "What, they *lost* the agreement!?"

I'll happy upload the patch when this is fixed.

We have a new system in place.  New uploads require agreeing to the license through the web site.  If you have any questions or concerns, feel free to talk to the person at Digium in charge of legal matters - Michelle Petrone (mpetrone@digium.com).

Hi Russell,

I am aware of the new system - and think it's a great idea for those who don't already have a disclaimer - makes things easier for both sides.

I work for a company. As in most companies, we're not in the business of giving extremely liberal (in favor of Digium) copyright licenses away for free, so getting the original disclaimer done was quite an involved process, involving CEO, legal, etc. This took me about two weeks to get organized and signed-off on the first time around.

Suggesting I go through this entire process again is just ludicrous - I'm trying to _give you code_!

Hi Russel, hi Nic,

did you aleready master the issue about the license? I´m really hungry for the patch written by Nic. I´ve got the same problem here with some "snom 300" and multiple hints to them. It would be a great favour for me!

btw: Does this bug still exist in asterisk version 1.4?

Thanks for your work!

By: Nic Bellamy (nic_bellamy) 2007-07-19 15:58:13

Nearly there with the license - discussed it with KPF @ Digium and my management, and there some actual changes in the v3.0 license that make legal sense. Going through the process of getting it approved internally at the moment. I was hoping to have it sorted in time to get the patch into 1.2.22, but that got fast tracked due to a number of security issues.

And yes, from reading the code, the bug does also affect 1.4 and trunk.

Hola! Did you get the licensing situation sorted out?

By: Nic Bellamy (nic_bellamy) 2007-10-29 18:09:14

Thanks for the reminder - I just prodded my boss again, and have just gotten approval, so I've submitted my request.

Awaiting confirmation that it's accepted.

License accepted, and a patch for the latest 1.2 and 1.4 branches attached.

closes issue ASTERISK-8547 - where the [catname](!) and [catname](othercat1,othercat2,...) notation gets dropped across a ConfigUpdate (or any other thing that would cause a config file to be written). While I was at it, I also cleaned up some of the destroy routines to free up comments, which was not being done. Made sure the new struct I introduced is also cleaned up properly at destruction time. My code handles multiple template inclusions. Many thanks to ssokol for his patch, which, while not literally used in the final merge, served as a foundation for the fix.

If someone were to delete the files used by an existing MOH class, and then
issue a reload, further use of that class could result in a crash due to
dividing by zero.  This set of changes fixes up some places to prevent this
from happening.
