[Freeswitch-users] mod_managed users?

Hello Lukasz,
Thanks for testing mod_managed. I apologize for the problems you've encountered, and I'll try to sort them out for you.
A few things first:
- Scripting support: This is made to allow "true" scripts, as invoked as an EXE - similar to the Lua and spidermonkey support. So, without a Main(), it won't compile as an EXE. If you aren't using it as a script, then an empty Main method will work fine.
- Entry points must be public for Mono. I'll update the demo code to make sure that Main is public. This is a bug in Mono's lightweight code generation -- it won't skip the JIT access checks.
As to the main problem of your DLL not working, can you send me the full source code, or all the logging output from loading it? Try "managedreload my.dll" to reload the DLL and see how it is registering them. It should output something like "Registering API FullName with Aliases fullname, shortname".
Thanks,
Michael

Hi,
I've just tried new mod_managed under Win32 and I get a weird behavior.
I try the example below:
public class DemoScript : IApiPlugin
{
public void Execute(ApiContext context)
{
context.Stream.Write(string.Format("DemoScripts executed with
args '{0}' and event type {1}.",
context.Arguments, context.Event == null ? "<none>" :
context.Event.GetEventType()));
}
public void ExecuteBackground(ApiBackgroundContext context)
{
Log.WriteLine(LogLevel.Notice, "DemoScripts on a background
thread #({0}), with args '{1}'.",
System.Threading.Thread.CurrentThread.ManagedThreadId,
context.Arguments);
}
}
It's just like the ApiDemo from Demo.cs
So When I copy DemoScript.csx to managed dir the console log is:
"
freeswitch at Zwierko-laptop> Loading

static 'Main' method
suitable for an entry point
"
Adding
"
public static void Main()
{
}
"
solves the issue. Is this how it's supposed to work?
Another strange thing is that when I compile this class to DLL (release)
it does not work at all...
freeswitch at Zwierko-laptop> Loading
c:\Users\Zwierko\Projects\fs\svn\Debug\mod\managed\FSScripts.dll from

API CALL [managed(DemoScript 111)] output:

DemoScript not found.
2009-07-28 21:13:03.542000 [ERR] mod_managed.cpp:393 Execute failed for
DemoScript 111 (unknown module or exception).
And another issue with scripts. I use script code as example:
"
public class ScriptDemo
{
static void Main()
{
switch (FreeSWITCH.Script.ContextType)
{
case ScriptContextType.Api:
{
var ctx = FreeSWITCH.Script.GetApiContext();
ctx.Stream.Write("Script executing as API with args:
" + ctx.Arguments);
break;
}
case ScriptContextType.ApiBackground:
{
var ctx = FreeSWITCH.Script.GetApiBackgroundContext();
Log.WriteLine(LogLevel.Notice, "Executing as
APIBackground with args: " + ctx.Arguments);
break;
}
case ScriptContextType.App:
{
var ctx = FreeSWITCH.Script.GetAppContext();
Log.WriteLine(LogLevel.Notice, "Executing as App
with args: " + ctx.Arguments);
break;
}
}
}
}
"
console log is as follows:

Again, am I doing something wrong in here?
Thanks, for any feedback
