Hi, I am having a problem connecting to LDAP database from dialplan using lua script. When I run the below script from xml dialplan it causing a coredump and Freeswitch crashes. The coredump looks like: Core was generated by `/usr/local/freeswitch/bin/freeswitch -nonat -nc -heavy-timer'. Program terminated with signal 11, Segmentation fault. #0 0x00002aaab6ff1720 in ldap_set_option () from /usr/lib64/libldap-2.3.so.0 (gdb) bt #0 0x00002aaab6ff1720 in ldap_set_option () from /usr/lib64/libldap-2.3.so.0 #1 0x00002aaab6dbb68a in lualdap_open_simple () from /usr/local/lib/lua/5.1/lualdap.so #2 0x00002aaab6b91704 in luaD_precall (L=0x14e12740, func=<value optimized out>, nresults=-1) at ldo.c:319 #3 0x00002aaab6b9a4a4 in luaV_execute (L=0x14e12740, nexeccalls=1) at lvm.c:587 #4 0x00002aaab6b91b4e in luaD_call (L=0x14e12740, func=0x14e12b20, nResults=0) at ldo.c:377 #5 0x00002aaab6b912a7 in luaD_rawrunprotected (L=0x14e12740, f=0x2aaab6b8ed40 <f_call>, ud=0x409f4e00) at ldo.c:116 #6 0x00002aaab6b91325 in luaD_pcall (L=0xffffffffb002d5d0, func=0, u=0x2aaab002d5b8, old_top=46912585783072, ef=0) at ldo.c:463 #7 0x00002aaab6b8ebc5 in lua_pcall (L=0x14e12740, nargs=0, nresults=0, errfunc=<value optimized out>) at lapi.c:821 #8 0x00002aaab6b76d61 in docall (L=0x14e12740, narg=0, clear=1, perror=0) at mod_lua.cpp:91 #9 0x00002aaab6b77194 in lua_parse_and_execute (L=0x14e12740, input_code=0x2aaab004c220 "ldapdirectory.lua") at mod_lua.cpp:183 #10 0x00002aaab6b77e92 in lua_function (session=0x14e5bb68, data=<value optimized out>) at mod_lua.cpp:414 #11 0x00002b027ace8cd9 in switch_core_session_exec (session=0x14e5bb68, application_interface=0x2aaaac0622d8, arg=0x14d75968 "ldapdirectory.lua") at src/switch_core_session.c:2048 #12 0x00002b027ace9176 in switch_core_session_execute_application_get_flags (session=0xffffffffb002d5d0, app=0x14d758e8 "lua", arg=0x14d75968 "ldapdirectory.lua", flags=0x0) at src/switch_core_session.c:1962 #13 0x00002b027ad57a1a in CoreSession::execute (this=0x14d74d60, app=0x14d758e8 "lua", data=0x14d75968 "ldapdirectory.lua") at src/switch_cpp.cpp:658 #14 0x00002aaab6b861c0 in _wrap_CoreSession_execute (L=0x2aaaac002050) at mod_lua_wrap.cpp:5678 #15 0x00002aaab6b91704 in luaD_precall (L=0x2aaaac002050, func=<value optimized out>, nresults=0) at ldo.c:319 #16 0x00002aaab6b9a4a4 in luaV_execute (L=0x2aaaac002050, nexeccalls=1) at lvm.c:587 #17 0x00002aaab6b91b4e in luaD_call (L=0x2aaaac002050, func=0x2aaaac012400, nResults=0) at ldo.c:377 #18 0x00002aaab6b912a7 in luaD_rawrunprotected (L=0x2aaaac002050, f=0x2aaab6b8ed40 <f_call>, ud=0x409f5800) at ldo.c:116 #19 0x00002aaab6b91325 in luaD_pcall (L=0xffffffffb002d5d0, func=0, u=0x2aaab002d5b8, old_top=46912585783072, ef=0) at ldo.c:463 #20 0x00002aaab6b8ebc5 in lua_pcall (L=0x2aaaac002050, nargs=0, nresults=0, errfunc=<value optimized out>) at lapi.c:821 #21 0x00002aaab6b76d61 in docall (L=0x2aaaac002050, narg=0, clear=1, perror=0) at mod_lua.cpp:91 #22 0x00002aaab6b77194 in lua_parse_and_execute (L=0x2aaaac002050, input_code=0x14de5e00 "helloworld.lua") at mod_lua.cpp:183 #23 0x00002aaab6b77e92 in lua_function (session=0x14e5bb68, data=<value optimized out>) at mod_lua.cpp:414 #24 0x00002b027ace8cd9 in switch_core_session_exec (session=0x14e5bb68, application_interface=0x2aaaac0622d8, arg=0x14e2f368 "helloworld.lua") at src/switch_core_session.c:2048 #25 0x00002b027ace9176 in switch_core_session_execute_application_get_flags (session=0xffffffffb002d5d0, app=0x14e2f360 "lua", arg=0x14e2f368 "helloworld.lua", flags=0x0) at src/switch_core_session.c:1962 #26 0x00002b027acec4ad in switch_core_session_run (session=0x14e5bb68) at src/switch_core_state_machine.c:176 #27 0x00002b027ace8720 in switch_core_session_thread (thread=<value optimized out>, obj=0x14e5bb68) at src/switch_core_session.c:1271 #28 0x0000003ce900673d in start_thread () from /lib64/libpthread.so.0 #29 0x0000003ce84d44bd in clone () from /lib64/libc.so.6 However if I run the same lua script from fs_cli it works fine.

[Freeswitch-dev] questions on the new mod_sms
by Seven Du 07 Oct '11

07 Oct '11

Fatastic! I cannot help to try the new mod_sms, and here's some quick questions for developers and I'm seeing what can I help with testing/coding etc. to speed this up. 1) I see no event when I use the chat app "fire" with /event all in fs_cli, is there a problem or unfinished code? 2) Also I see nothing when I use the "send" app, I guess a catch all chatplan with <action application="send" data=""/> would have the same effect as before(when no mod_sms). I tried with a. unload mod_sms, two US send text messages to each other without problem b. load mod_sms, I see this log but nothing happened 2011-09-24 10:03:48.921888 [INFO] mod_sms.c:299 Processing text message 1004->1001 in context default Chatplan: 1001 parsing [default->demo] continue=false Chatplan: 1001(a)192.168.7.2 Regex (PASS) [demo] to(1001(a)192.168.7.2) =~ /^(.*)$/ break=on-false Chatplan: 1001(a)192.168.7.2 Action send() 2) How to get variables in lua? will there be an event object like session in dialplan based ? 3) also I see the chat api also hit the chatplan, is that supposed to? Sorry for so many questions, thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

Hi, I'm writing some part of dialplan in lua and after bridge a have to execute an application. I receive this: "Channel is hungup, aborting execution of application: antani-postdial". Of course i've tried all the kind of app interface flags.my dialstring contains right variable:2011-10-07 13:07:51.817103 [DEBUG] switch_event.c:1168 Parsing variable [continue_on_fail]=[true]2011-10-07 13:07:51.817103 [DEBUG] switch_event.c:1168 Parsing variable [hangup_after_bridge]=[false] p.s. in the docs i can find "SAF_ZOMBIE_EXEC" but it's not in my switch_types.h what can i do to exec my postdial application in my lua? dialstring="{ignore_early_media=true,originate_timeout=90,continue_on_fail=true,hangup_after_bridge=false}"..dialstringlocal sessionB = freeswitch.Session(dialstring);freeswitch.bridge(session, sessionB)session:execute("antani-postdial", i); Thank you! =) E' nata indoona: chiama, videochiama e messaggia Gratis.

[Freeswitch-dev] MOH in async mode is possible?
by Vu Quang Hoa 07 Oct '11

07 Oct '11

Hi everyone, I've been trying ways to provide MOH in background of Lua script (searching and found few way) but none of them really satisfied me. I think it may implement in the same way of record_session function. So I need your advises if it is possible or not? It's a really good idea? Thank you! vutamhoan

[Freeswitch-dev] memory pool
by succer110＠tiscali.it 03 Oct '11

03 Oct '11

Hi! I'm a new fs module developer :) In the page "authoring freeswitch module" i read that "there's still times when using traditional C memory management is a better plan." How can i recognize that cases? >From what i have understood using memory pool from apr i can forget to call switch_core_destroy_memory_pool unless i specifically want it. Am i Right? Is possibile to specify the dimension of the memory pool i want to create? Which is the standard dimension? Thankyou =) E' nata indoona: chiama, videochiama e messaggia Gratis.
