If you did it from the pool passed to you in the module init its safe if you made your own pool it must be destroyed. Like I said, everything you do in the init that has an undo must be called, including 3rd party libs you may be using. You are unloading the module from memory so nothing can linger.

[Freeswitch-dev] TraceMonkey
by Jan Berger 02 Jul '10

02 Jul '10

Hi, Was searching for updated JavaScript alternatives and found this Tamarin/TraceMonkey. Do anyone have experience with this version? They claim a 5-10 x speed increase compared to the older SpiderMonkey "Tamarin is a JavaScript <https://developer.mozilla.org/en/JavaScript> engine written in C++. It currently implements Adobe ActionScriptT 3 (a superset of ECMAScript Edition 3) and is embedded within the AdobeR FlashR Player versions 9 and later. Tamarin's jit-compiler, NanoJIT, is also used in TraceMonkey <https://wiki.mozilla.org/JavaScript:TraceMonkey> ergo SpiderMonkey, which is Mozilla's JavaScript engine in Firefox." https://developer.mozilla.org/en/Tamarin#Get_Involved! Is anyone interested in having a mod_tracemonkey for FreeSWITCH - or is someone already working on this? Jan

So in short - if a call executes a long script the other calls will be queued unable to process events - V8 is a joke as a scripting environment if you can't create multiple environments. I kind of see a poor IVR developer that accidentally made an ever loop and the entire companies phone system is down :-) Obviously - I can get around it using several processes, but processes are bloody expensive on any OS. --- Will have a chat with the Danes about this one - thanks.

The problem with v8 threading is really simple. 1. Google V8 only allows one context to execute at a time. 2. If you are using multiple context design, they must be executed using exactly the same thread via a single event loop. Failure to do this will result to a corrupt stack.

Hello! I've made one module with one api function and one app function. I added one extension to call my app. I only print a console message whitin the app function.
