[Freeswitch-users] mod_python post-processing after hangup

[Novak Joe]

Hi,

  I received loads of useful hints on IRC yesterday regarding this
problem, and as a result was able to come up with a decent solution
which just involves using the API and 'runtime' functions to run my
post-processing job in a thread after hangup.  I don't think it is
possible to pass objects via this method, but what I've worked out is
sufficient for my needs.

  I also updated the wiki to include this example in hopes of saving
the good souls at IRC from having to repeat this again.
  http://wiki.freeswitch.org/wiki/Mod_python#Run_something_in_a_thread_using_API

  I'd also appreciate it if someone could take a look at the wiki and
confirm that the example I've described is appropriate.

  If possible, I'd also like to add something about usage of the API
in general.  I spent a good amount of time searching about on my own,
but still ended up asking some pretty silly questions in this vein on
IRC.
  I'm still a bit shaky regarding what is what, as the word API
appears in many different places throughout the wiki but appears to
refer to several different APIs.  The mod_python API wiki entry refers
to the Lua entry, and the Lua entry simply provides an example of how
to instantiate a new API object, which is then followed by a lengthy
section titled API:
http://wiki.freeswitch.org/wiki/Mod_lua#API
  which doesn't mention the executeString method anywhere except in
the context of stream:write.

  The one I've actually been interested - I think! - is this guy,
http://www.freeswitch.org/docs/class_a_p_i.html

  If I can get confirmation/further_explanation of this, I'll be happy
to update the mod_python wiki accordingly, and hopefully stave off
this particular variety of confusion in future!

  Cheers,
   Joe
