[Freeswitch-dev] Seeking collaborators for FreeSWITCH/Lua scripting toolkit
by Chad Phillips 22 Jan '16

22 Jan '16

Looking for folks in the FreeSWITCH community who would be interested in collaborating on an open source scripting toolkit I've written for FreeSWITCH/Lua. The basic idea is to have ready made solutions to common scripting needs, so as not to reinvent the wheel. The original project was written in 2010. A lot of it still works great, and there are some design flaws that I'd like to work out in the next release. Project code is here: https://github.com/thehunmonkgroup/jester Some background and reasoning for the project here: http://xylil.com/2016/01/20/jester-freeswitch-lua-and-my-quest-for-an-aweso… If anyone is interested in helping, please let me know! Chad

[Freeswitch-dev] Crash in v1.6.5
by Alex Balashov 02 Jan '16

Hi, I'm running v1.6.5:70b8c17, and recently ran into this crash scenario: (gdb) where #0 switch_core_session_get_channel (session=0x0) at src/switch_core_session.c:1357 #1 0x00007f955ec53ce9 in sofia_update_callee_id (session=0x0, profile=0x1a7ce80, sip=0x7f940c20b728, send=SWITCH_TRUE) at sofia.c:1086 #2 0x00007f955ec59e55 in our_sofia_event_callback (event=nua_i_update, status=200, phrase=0x7f9525d82270 "OK", nua=0x7f953c0120e0, profile=0x1a7ce80, nh=0x7f944fc705a0, sofia_private=0x7f944ef34460, sip=0x7f940c20b728, de=0x7f953c012d40, tags=0x7f9525d82260) at sofia.c:1594 #3 0x00007f955ec5f4fb in sofia_process_dispatch_event (dep=<value optimized out>) at sofia.c:1983 #4 0x00007f955ec60266 in sofia_msg_thread_run (thread=<value optimized out>, obj=0x7f955ebf5ad8) at sofia.c:2031 #5 0x00007f95625f899b in dummy_worker (opaque=0x1a732d0) at threadproc/unix/thread.c:151 #6 0x00007f95617a2a51 in start_thread () from /lib64/libpthread.so.0 #7 0x0000003acfae893d in clone () from /lib64/libc.so.6 Specifically, the crash was on an assertion that tried to dereference a null session pointer: #0 switch_core_session_get_channel (session=0x0) at src/switch_core_session.c:1357 1357 switch_assert(session->channel); However, while I am a C programmer, I don't know the first thing about FS internals and thus don't know what else to look for in this core dump so as to make a useful report. My assumption is that a check for NULL session pointer somewhere in frames 0/1 isn't really an adequate compensatory mechanism because the root of the problem lies elsewhere. I did manage to track down the definition of Sofia's 'sip_t' structure and, it looks to me like this happened while either generating a 200 OK response to an UPDATE request: (gdb) print sip->sip_request->rq_method $1 = sip_method_update And it doesn't appear to be in the course of processing a reply, because the status substructure seems blank: (gdb) print sip->sip_status $2 = (sip_status_t *) 0x0 However, I don't know how to get at the raw message buffer of the UPDATE request.
