Hey Vitalie :) Thanks for suggesting Lua. We are keen on Lua but does it support multi-threading. I could see this http://stackoverflow.com/questions/2978120/multithreading-in-lua http://kotisivu.dnainternet.net/askok/bin/lanes/ But how stable is multi-threading in Lua ? Currently, we are using python stackless for running multi-threaded IVR in FreeSWITCH but we are not happy :( regards, Anita On Fri, Feb 24, 2012 at 2:29 AM, Vitalie Colosov <vetali100@gmail.com>wrote:
Why not to use powerful and fast lua scripts with DB access - example for DB select: ------------------------ subscriber = "1000"; my_field = ''; local dbh = assert(freeswitch.Dbh("db","fs_user","fs_password")); dbh:query("select my_field1 from my_table1 where subscriber = '"..subscriber.."'", function(row) my_field = row.my_field1; end); dbh:release(); --do whatever you need here!! ------------------------
obviously you need to configure ODBC for access, but this is described: http://wiki.freeswitch.org/wiki/Using_ODBC_in_the_core#CentOS_5.2

Hi
We are considering writing our own module for processing IVR in C. We are considering using mod_event_socket and then modify it to consume and produce the events internally instead of passing them to the socket. Is this a good idea?
I know FreeSWITCH already has a mod_dialplan_xml which can use mod_curl to communicate to the outside world for I/O and DB access. But ...
1) Does XML have all the power flexibility that will be needed for powerful IVR applications?
2) Does mod_dialplan_xml use a separate thread for each IVR execution ? What will be the overhead of interpreting the XML ?
3) Any more ideas ?
Thanks :)
regards, Anita
