FS-3918: git commit: f91bdf12aa1854da04775933a40f444e613775b5
by Nuno Reis 02 Sep '13

02 Sep '13

Hi Ken. I've recently upgrade my FS environments to the latest stable 1.2.12. I've found that everytime i entered a conference it resulted in a segmentation fault. When digging on the problem i found that it is related with the commit referenced above. Basically i had to set the conference_moderator_pin channel variable when entering a conference otherwise i have a segmentation fault in FS. Regarding this issue my question is why did you make the mdpin pointer variable a const? I would like to hear about your thoughts on this. Thanks.

accessing key presses with outbound event socket
by Jamie McClelland 02 Sep '13

02 Sep '13

Hi all, Thanks again for your help in completing our simulataneous interpretation system using freeswitch[0]. I'm now trying to add the ability for users to enter the conference number they would like to join. I see lots of examples for doing this, but none that are using an outbound event socket. With event socket, I can capture dtmf digit events *after* the user enters the conference call. But I am having trouble first prompting the user to enter the conference number and then capturing their output and using it to determine which conference room to sent them to. I'm using fiorix's python event socket code [1]. So far I've been experimenting with the read command[2]. However, I'm not sure how to retrieve the digits pressed after calling this command. Is their a command that can query freeswitch to get the value of the variable I set with the read command? Any help would be greatly appreciated. jamie 0. http://lists.freeswitch.org/pipermail/freeswitch-dev/2013-February/006406.h… 1. https://github.com/fiorix/eventsocket 2. http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_read -- May First/People Link Growing networks to build a just world http://www.mayfirst.org https://support.mayfirst.org OpenPGP Key: http://current.workingdirectory.net/pages/identity/

Event dispatch overview
by Ola Bäckström 28 Aug '13

28 Aug '13

Hi all, I've been trying to control eavesdrop with events the last couple of days, but not succeeded. Since I needed to know more how events are dispatched internally to the different channels I've been diving into Freeswitch source code to get some insight. I thought I could share what I found, and hopefully get some comments or correction. Especially on what I did not find out ... in particular I haven't understood where/how the event dispatch to channels work, I call it "Magic" below... ** Overview of the Freeswitch event system (see the file src/include/switch_event.h for an overview in the code) 1. At the core there is an event dispatch queue. (see switch_events.c) 2. Subscribers can request to be notified when specific events are handled. All mod_xxx stuff does this, see mod_erlang_event, mod_dptools etc (see switch_event_bind(...) function, used to register a handler function for specific events) 3. Events can be created anywhere in any thread (see switch_event_create*-functions) and edited, by adding key-value pairs called headers (see switch_event_add_header(...) function). Example of this can be found in mod_event_test.c function torture_thread(...). 4. Such an "unsent" event can be put into the event dispatch queue (see switch_event_fire(...), that function calls switch_event_queue_dispatch(...) that finally calls switch_queue_push(...) to push it onto the queue) 5. Later... will all relevant subscribers will get their callback handler function called with the event. **Event handling inside a channel Each channel contains a couple of queues: event_queue, message_queue, signal_data_queue, private_event_queue, private_event_queue_pri. (see the type switch_core_session_t that equals the struct switch_core_session found in include/private/switch_core_pvt.h) To make sure an event ends up in one specific channel queue the correct headers must be added between step 3 and 4 above. (see switch_channel_event_set_data(...) ). Example of this can be found in switch_ivr_async.c function switch_ivr_broadcast(...), or in mod_dptools.c where all dialplan commands are implemented. Then by some unclear mechanism "Magic" will the event leave the central event dispatch queue and end up in one of the channel queues. **Core State machine Unclear what role it has, but switch_core_state_machine.c has a mechanism to call driver state handlers depending on the channel state. Events does not seem to be directly involved in those calls. Regards /Ola

Authoring Modules, moving mymodule.conf.xml to autoload config
by Joel Dodson 27 Aug '13

27 Aug '13

Hi, I'm writing a new module for some specific functionality we need. I've been going through the wiki page for Authoring Modules (http://wiki.freeswitch.org/wiki/Authoring_Freeswitch_Modules) and it's been helpful. I have mod_mymodule (copied from mod_skel) compiling and running locally. I've also been looking through mod_event_socket since my module will be very similar. I'm stuck now on getting the config file I've included in my module to be automagically added to the autoload_configs directory. I've added a conf directory to my module similarly to how event_socket does it. I've built my module (make mod_mymodule and make mod_mymodule-install) but mymodule.conf.xml still is not moved automatically into the autoload directory. I do have mod_mymodule included in modules.conf when I build and install. I've even tried running bootstrap.sh and configure again with my mod_mymodule in the source code. Do I need to manually copy over mymodule.conf.xml when I do a freeswitch install? Is there another file I need to add mod_mymodule to to get the config copied over automatically? I'm doing this on the latest 1.2 branch from github, I've tried it on master as well, same results. thanks, Joel
