[kamailio] avpops: avp_copy add xavp (#7)
by Victor Seva 07 Oct '19

07 Oct '19

We have avp_copy on avpops module but we don’t have anything to copy xavps. ``` // copy all the content of an avp to a xavp $xavp(a[0]=>b) = $(avp(x)[*]); // deleting left content $xavp(a[0]=>b[*]) = $(avp(x)[*]); // copy xavp to a xavp with index $xavp(a[0]) = $xavp(b[1]); // all $xavp(a[*]) = $xavp(b[*]); // copy all content of a xavp to a avp $avp(x) = $xavp(a[0]=>b[*]); ``` --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/7

Outbound flow failure handling merged to master
by Hugh Waite 23 Nov '16

23 Nov '16

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

[kamailio] debugger: config test report (#8)
by Victor Seva 24 Jan '16

24 Jan '16

In testing environment It would be nice to be able to append sip headers `X-Kamailio-test` and `X-Kamailio-test-ID` as a way to identify a collection of request/responses related to a a single test. Be able to generate tests reports via debugger RPC command using the value of `X-Kamailio-test` as key. The content of report could be: * SIP message received * SIP messages sended * flow of config execution routes ( `start`, `end`, `exit` ) * list of the variable and its value --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/8

Re: [sr-dev] Is there a sense in calling run_onsend() after the msg_send() function?
by Lucian Balaceanu 08 Sep '15

08 Sep '15

Hi Daniel, I must admit this run_onsend() patch for stateful replies creation was not quite a success story. However, I think it serves a practical purpose, for example in Homer tracing and could be useful for the community. Again, I propose my past solution, with some questions: 1. I am unsure if the place I introduced the run_onsend call is appropriate since the buf used for msg_send is constructed build_res_buf_from_sip_req and build_res_buf_from_sip_res calls. 2. Also, we can maybe unite these if call branches I created: send_res = msg_send(&uas_rb->dst, buf, res_len); send_res = SEND_PR_BUFFER( uas_rb, buf, res_len ); 3. Do you think a get_send_socket snippet as follows should be inserted before the /*if (onsend_route_enabled(SIP_REPLY)){*/ : if(dst.send_sock == NULL) { dst.send_sock=get_send_socket(msg, &dst.to, dst.proto); if (dst.send_sock==0){ LM_ERR("cannot forward reply\n"); } } Thank you, Lucian On 10/29/2014 02:15 PM, Daniel-Constantin Mierla wrote: > Hello Lucian, > > I applied your patch with some fixes. > > I haven't checked with stateful replies, at some point a function from > core should be used.

TM possible deadlock
by Jason Penton 09 Apr '15

09 Apr '15

Hi All, I have been experiencing a deadlock when a timeout occurs on a t_relayed() INVITE. Going through the code I have noticed a possible chance of deadlock (without re-entrant enabled). Here is my thinking: t_should_relay_response() is called with REPLY_LOCK when the timer process fires on the fr_inv_timer (no response from the INVITE that was relayed, other than 100 provisional) and a 408 is generated. However, from within that function there are calls to run_failure_handlers() which in turn *could* try and lock the reply (viz. somebody having a t_reply() call in the cfg file - in failure route block). This would result in another lock on the same transaction's REPLY_LOCK.... Has anybody else experienced something like this? this is on master btw. Cheers Jason

Refreshing the Kamailio logo
by Daniel-Constantin Mierla 16 Feb '15

16 Feb '15

Hello, I was considering to discuss the state of Kamailio project logo for a while. The current state is ambiguous, to say at least - various logos in different places. When OpenSER was renamed in Kamailio we were trying to get something new, but due to the 'forks and dark waters' at that time, this process was never completing, meanwhile using an adaptation of old openser logo. However, there are no high resolution or other variants suitable for using in particular conditions (e.g., black and white, big posters). First, a question that we should decide on: shall we aim for a new logo or try to get someone to make proper graphics from the current shape? (for reference, the logo from http://www.kamailio.org/wp-images/kamailio-rock-logo.jpg). I would prefer to go for a new logo, but I admit that this process can become complex, a mater of tastes, not something we can decide on technical aspects. Therefore, if it ends up in something that doesn't seem to have the acceptance of major contributors (with coding, advertising/promoting, ...) to the project, then we stick with current for a while. My preference is based on the fact that Kamailio evolved over the time, has its own identity, so a fresh look of the logo would reflect that better. I am listing here the options, that people can express preference on: A) New logo A1) variant based on Kamailio World logo (used by twitter kamailioproject account and on some materials at various events). It was a backup variant so far as we had high resolution graphics that could be adapted to get a good image for big posters. Can be seen at: - http://www.kamailio.org/pub/kamailio-logos/variants/kamailio-from-world-log… - http://www.fredposner.com/1471/kamailio-at-astricon-2013/ A2) use a professional service for that. Kamailio World logo was made with 99designs.com service, which is quite good considering there will be many submissions to choose between, options can be visible by everyone. There might be other similar services, this is one I have experience with and worked fine in the past -- anyhow, it has to be something that all management and solution can be done online. Asipto can sponsor at least the bronze package if 99designs is going to be used, maybe others want to participate with extra funds to get a better package. A3) leverage on community, in case some companies have internal designers or some of you have such skills or friends. Perhaps this has the highest risk on escalating, given that is going to be some direct involvement in proposals and selection. B) Old logo B1) get someone to produce high resolution graphics from existing logo No matter what variant, who will do the work or financial contribution, will get credits via our web site. However, all the rights of the resulting logo will belong to the Kamailio project. To conclude, the order of my preferences: A2, A1, A3, B1 Looking forward to feedback from many of you!

by borikinternet 20 Jan '15

20 Jan '15

In this pull request I`d correct work with retrieved from RADIUS AV pairs for modules auth_radius, misc_radius and peering. Now this modules correctly put to $avp() all retrieved params: - integer name and integer value - integer name and string value - string name and integer value - string name and string value All above said and for SIP-AVP params too.
