[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 22 Oct '12

22 Oct '12

Hello again! Another busy week in the land of FreeSWITCH. As you know we have been doing some work on the FreeSWITCH project's infrastructure. We are happy to report that this work is essentially complete. Thank you for your patience in this process. We've experienced intermittent outages but thanks to the efforts of Brian West and Raymond Chandler these have been kept to a minimum. We also thank Ken Rice for his hard work during this time. His knowledge and experience have been invaluable. Last week we had a very interesting discussion<http://wiki.freeswitch.org/wiki/FS_weekly_2012_10_17>from Chad Engler about his nodesl <https://github.com/englercj/node-esl> library - a connector between node.js and ESL <http://wiki.freeswitch.org/wiki/Esl>. Chad describes himself as a Web developer learning the telephony side of things. However, we were all impressed with how much knowledge he had with using ESL given the relatively short amount of time he's been working with it. This week<http://wiki.freeswitch.org/wiki/FS_weekly_2012_10_24>we will be looking in on some Windows-centric ways of handling real-time data and related PBX items. The following week, on October 31, we will be hearing from our friends over at Redshift Networks<http://www.redshiftnetworks.com/>. They will be giving us close-up look at some of the worldwide SIP attacks that are being perpetrated against FreeSWITCH and other IP telephony servers. On a personal note I would like to thank everyone who volunteered to be a technical reviewer of the new edition of the FreeSWITCH book<https://www.packtpub.com/freeswitch-1-0-6-build-robust-high-performance-tel…>. I was overwhelmed with just how many people who are willing to volunteer their time. Packt Publishing will be contacting those who've been selected for this important job. This is a great community and we are all glad to be a part of it. Take care and have a great week. -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

[Freeswitch-dev] Shell script equality tests and portability
by D'Arcy J.M. Cain 22 Oct '12

22 Oct '12

I have just started creating the NetBSD FreeSWITCH package. As mentioned in an earlier post (assuming the the moderator puts these through in the same order that I sent them) I have created the music and sounds packages. Now I am working on the core package. The first issue I came up with is equality testing in some of the shell scripts. The issue is the usage of "==" instead of "=". While the former works on some shells, it is not portable. I believe that the latter is portable. Shall I submit patches? -- D'Arcy J.M. Cain System Administrator, Vex.Net http://www.Vex.Net/ IM:darcy@Vex.Net

Re: [Freeswitch-dev] Share data between modules
by Peter Olsson 21 Oct '12

21 Oct '12

I believe the threading model in zmq is different, that it really doesn't work well together with FreeSWITCH's threading model. If I've understood this correctly, for instance when you send a message using zmq, the library takes for granted that this is always done from the same thread. However, inside FS it means it might be sent from different threads, since the event system inside FS has multiple threads to pop the queued events. Tony, probably has a more correct description - I've never even used zmq myself :) /Peter Från: freeswitch-dev-bounces(a)lists.freeswitch.org [mailto:freeswitch-dev-bounces@lists.freeswitch.org] För Juan Antonio Ibañez Santorum Skickat: den 17 oktober 2012 13:37 Till: freeswitch-dev(a)lists.freeswitch.org Ämne: Re: [Freeswitch-dev] Share data between modules Any idea to improve it? 2012/10/16 Anthony Minessale <anthony.minessale(a)gmail.com<mailto:anthony.minessale@gmail.com>> You should do that by firing events from your module so they are delivered via mode_event_zmq. Beware zmq is unstable in FS because its a threaded app and zmq is a different threading model.

[Freeswitch-dev] memory leak in freeswitch?
by rentmycoder rentmycoder 19 Oct '12

19 Oct '12

Hi guys, I've found a memory leak, and I need your great help to find why is this happening... The situation is simple: I execute a simple bash script using lua popen function as documented in wiki on an extension from the xml dialplan... After 1000 calls the memory usage gets 60Mb and after 10.000 calls, 120mb... Freeswitch becomes very unresponsive and after a time the sip profiles stop working... If I uncomment the popen call in lua, memory leak does not occure... The lua script: function shell(c) local o, h h = assert(io.popen(c,"r")) o = h:read("*all") h:close() return o end sesson:answer(); while(session.ready()) { local testvar=shell(/opt/test.sh) session:sleep(1000); } sesson:hangup(); The test.sh script: !#/bin/bash echo 12345678901234567890123456789012345678901234567890123456789012345678901234567890 Thats all... Tha script just writes to standard output and the lua script reads it into a variable... I would like to use this mechanism to communicate with an external process... This worked well with asterisk anyway... Question#1: what is the reason of this memory usage and how to fix it? Question#2: if not possible, how to communicate with an external process preferably via TCP? I've tried lua sockets, but same memory leaking occurred... Tested on: Freeswitch 1.2.3 on debian6 32bit, x86, 4GbRAM Stress test environment: another FS instance registers as a user and start calling target extension with a random (30-60 sec) call timeout... Monitors call count and if call count falls below 100, starts new calls as needed... So there are always 100 live concurrent incoming calls on the test system... which maximum length of 1 minute. Thanks a lot... John

[Freeswitch-dev] Share data between modules
by Juan Antonio Ibañez Santorum 17 Oct '12

17 Oct '12

Hello, Is there any way to share data (as a hash) between modules? I can see switch_core_set_variable() function but I think it cannot be used for that purpose. Regards
