Re: [Freeswitch-users] Precompiled Windows Binaries
Carlos, Do you have any documentation or scripts for your builds? I'm interested in having a working automated build and installer build process, and I'm curious if there's any work you've done that can make my job easier. :) Thanks, Josh On Wed, Nov 4, 2009 at 6:51 AM, Carlos Talbot wrote: > > I usually try to update the svn file at least once a month.

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
One more addition added. The loader process now looks for the string ".primary" in the filename. If it exists, it loads the dll into the primary appdomain and executes to Load() routine on implementors of IPrimaryAppdomainExtension. I also added an example showing the use of this to display a WinForm logger. http://github.com/joshrivers/FreeSWITCH.Managed On Sat, Sep 26, 2009 at 10:28 PM, Josh Rivers wrote: > The ability to directly create swigtypes...that's huge!

The ability to directly create swigtypes...that's huge! I'd love to see some examples of how to use that. I've update my refactoring to include the changes to the trunk up through r14981. I've also checked in updated binaries that should work with the latest trunk builds(I hope?) A question occurred to me: would it make any sense to push the plugin loader into a separate DLL? That way we could keep the P/Invoke layer very cleanly separated from the loader/process host/abstraction layer structures.

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
I don't know what we'd want to write endpoints for, so I'll leave that one alone... ;) I do, however, agree with you on the event handler idea. My work on the module system is largely a precursor to putting in some work on a pub/sub event bus in managed code. I wanted some lifecycle and exception handling control that wasn't easy in the existing dll and I wanted to be able to create it without breaking stuff for other people. My question is this: is an event bus a good thing to put in mod_managed, or should it be an optional plugin that you load in?

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
Sorry for fading off for a few days. Having too much fun doing stuff! A few responses: On Thu, Sep 24, 2009 at 1:01 AM, Michael Giagnocavo wrote: > A few questions I have: > > Testability – is this even remotely practical? > I've seen three areas of testability: 1) Interop 2) Module Extensibility Framework 3) Modules and Plugins The interop testability picture is not an area I'm very familiar. I imagine you could write a native mod_managed.dll testing shim and test against that. I think this would have some limited value. It would confirm that interop layers behaved as expected, but not much more. The biggest values would be a) verifying that the api doesn't change accidentally, and b) providing a good way of adding bug-solution cases when the behavior of the core is causing a failure that we need to provide some padding around. The extensibility portion is very easy to write tests for. The module loader framework that I've refactored out of your code is completely stupid about the unmanaged code. It blindly passes the pointers through to the consumers that want them, and all of the module loader responsibilities are in managed code and mostly coded to interface. Very easy to mock and test. Finally the plugin testability story. Currently this is harder, since the plugins are written to talk to a lot of static methods and direct unmanaged types. As things evolve, I'd want to create a updated plugin interface that passes all the interop points by interface. The unit testing responsibility for an app or api plugin should primarily be that for a given set of inputs or responses, it makes a specified set of calls. That should be possible to mock and test in managed code if we provide a thin managed interface layer over the P/Invoke|SWIG layer. I'm currently writing a plugin that does just this, but I have the interface layer inside my code. Not everyone should have to write their own though? > Modularity – I agree there are two parts.

I hope I can clarify my intent, because I think I've been unclear on it so far. A) Philosophy: I have two principal concepts that are guiding me in my push towards modularity. 1) Single Responsibility Principal: "Each class or code file should only have one reason to change." I don't think I'm quite here in the code I've shown you, but it's getting closer. (I could definitely use help.) The idea here is that the class that monitors the plugin directory shouldn't also load the files. The class that loads the files shouldn't be responsible for configuring and creating app domains. Neither of those classes should have concrete logging code in them. The good thing about this is that you don't have to worry about breaking the loader when you change the watcher, and vice-versa. If we later decide to change the watcher so that it only checks for updates manually, we don't need to even let the loader know. 2) Open-Closed Principal: "Classes should be open for extension and closed for modification." The idea here is that once we've written a working class that has it's bugs ironed out and it's unit tests written, we shouldn't (ideally) ever need to change it. If we need a new behavior, we can just subclass the original, or implement the same interface, or whatever, and use the new class instead of the old one. If everything is nice an loosely coupled, we can just slide the new implementation in for improved behavior without changing the old one. What this means for the module system is that we can create new functionality without breaking old functionality. B) Actual uses: (Please note, that in most cases, I don't think that mod_managed needs to build out these functions, rather, I think mod_managed should "get out of the way" and let developers plug in what they want) 1) Commercial PBX Developer/Distributor: Case: Say I want to write my own FreeSWITCH distro/UI/packaged software on Windows, and I want to do all of my development in managed code and I don't care about plugins or anything. Answer: recompile my managed.dll with just a few changed lines in Loader.cs and your code controls everything coming into mod_managed. Ultimate power. Roll your own. Use it to launch a UI. Go nutz. 2) Complicated interwoven plugins: Case: I want to write a bunch of plugin dlls and have them all cross-communicate and share caches and statics. Answer: provide your own implementation of IModuleLoader and plug it into the registry. Now you can eliminate all of those pesky appdo

AppDomains, and In-Process Remoting in the last week. My refactoring had the following goals (in no particular order) - Testability - I'd really like to see a decent unit test suite on the more module so that we can change it with confidence.

It's very hard to do isolation testing with classes making direct calls out to a static Log class that in turn pinvokes out to unmanaged code. 2) I'd like to allow folk to make changes to the default behavior (optimally) without recompiling managed.dll. One thing at issue here is that there are two principal purposes for managed.dll. The first is to provide an interface into unmanaged code. The second is a module/plugin extensibility framework. The first purpose should absolutely provide the thinnest layer possible. The second purpose is very likely to need a lot of change and adaptation as people come up with development models that they would like to follow in using freeswitch. The extensibility framework should be mostly managed code, coded to interfaces for mock-ability and testabiliy. It should also be able to just push it out of the way and hook your own extensibilty framework in instead. > Going away from the core as far as adding .NET specific features (like > look at the static ManagedSession.Originate that takes hangup delegates, or > the “nice” wrapper for Log (Write and WeiteLine, with an enum instead of a > string) are keeping close to the core, just adding a tiny bit of API > cleanup.

I would like to see these things made available by interface rather than concrete implementation. It's currently not possible to test a plugin without loading it into FS. That precludes automated testing, and leaves a pretty big round-trip to test a tweak. I'm a sloppy coder too, so I'm always introducing interesting regressions, and that's why I like doing my testing without having to bring up a full process :) > Things like making a published SOAP interface for FS seem not really > related to mod_managed.

Although there is a slippery slope since we're building in an extensibility model. I don't think a WCF host, or a winforms host, or any of that should be baked in. Rather, I think we should provide the hooks for adding such a thing. If somebody wants to build ESL via WCF, why should they need to leave managed code? If the module system is general enough, then such a thing should just be a module. (BTW, I think WCF-Mono is getting there http://www.mono-project.com/WCF_Development) Absolutely, everything in mod_managed and managed.dll should run on mono and the CLR. However, there shouldn't be any reason that a Win-only developer can't build a complete FS application framework that plugs in and only runs on Windows. > As for all the rest of it, can we talk interactively, perhaps with other > users interested in mod_managed?

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
I'm only concerned with the difference in treatment.
public class CrashFreeSWITCH : ILoadNotificationPlugin
{
public bool Load()
{
ThreadPool.QueueUserWorkItem((o) => { throw new
NotImplementedException(); });
return true;
}
}
Crashes the entire switch, terminating all calls and disconnecting from the
PSTN.
public class CrashFreeSWITCH : ILoadNotificationPlugin
{
public bool Load()
{
throw new NotImplementedException();
return true;
}
}
Logs a message to the console and doesn't load the module, while leaving the
switch operating.
In my experience, exceptions in multi-threaded code: a) happen, b) are hard
to diagnose. Is the best behavior for the environment to crash, providing no
diagnostic information? That's hard in development, and even harder in
production. I suppose 'terminate switch on fault' should be an option, to
allow the operating system to restart the whole process on fault conditions,
but if that is the intended result, shouldn't any fault do the same thing?
What if the billing was happening in my second code block?
Normally, I'd trap the ThreadException and UnhandledExceptions in my
application, so that my code could choose the correct actions to perform
should the application get into an unknown state. This can include
terminating the whole application, but also logging diagnostic information,
trying to save uncommitted data, and sending notifications of the failure.
Is 'crash if it's a thread, but not if it's not' good because it's the way
the module works now, or is it a better design for a reason I'm not
understanding?

Re: [Freeswitch-users] Implementing h extension in FS
You should be able to handle hangups in one of two ways:1) Register a hangup
handler in your script or dialplan. This will execute a script on the hangup
of the call.
2) Use the Event Socket Layer(ESL) to listen to hangup events and then
perform your actions there.
You can find more about these options in the wiki.

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
The question is whether the CLR should take down the whole phone server due
to an unhandled exception...definitely the CLR should terminate...but
shouldn't it just log the exception to the console, not crash the core?

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
I have a new thought on the crashes...I'm able to crash FreeSWITCH any time
I like, just by having an exception in a thread.
public class CrashFreeSWITCH : ILoadNotificationPlugin
{
public bool Load()
{
ThreadPool.QueueUserWorkItem((o) => { throw new
NotImplementedException(); });
return true;
}
}
Perhaps Application.ThreadException or AppDomain.UnhandledException need to
be trapped?

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
It does from a fresh start of FreeSWITCH. I've noticed, although not really
confirmed, a race condition between the unload and reload of managed code.
It seems that threads started in the newly submodule are terminated along
with the threads for the old, unloading submodule. Is that what you are
seeing as well?

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
A new discovery:public bool Load()
{
ThreadPool.QueueUserWorkItem((o) =>
{
Log.WriteLine(LogLevel.Notice, "Thread Starting. ");
EventConsumer con = new EventConsumer("all", "");
while (true)
{
Event ev = con.pop(0);
if (ev == null) continue;
Log.WriteLine(LogLevel.Notice, "Event: " +
ev.serialized_string);
}
});
return true;
}
Does not crash. (Adding the null check prevents crash.) The backgrounded
loop runs fine. Looks like the event object goes straight to pinvokes, so a
null result just crashes?
I like the idea of a 'startup-script' for mod_managed. It would also be
excellent if there was an event or message informing the background code to
terminate nicely when the module reloads.

Re: [Freeswitch-users] Using mod_managed to create full FreeSWITCH modules
Thanks for the response Raffaele, I've successfully gotten the plugins to work. What I'm looking for is a way to write a lower-level FreeSWITCH module, as is implied by the wiki document. Mostly I'm trying to get something that runs stably in it's own thread from switch startup. Josh On Mon, Sep 7, 2009 at 11:00 PM, Raffaele P.

Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
Thanks for the response!
I have tried putting a long-running loop here, but then it blocks anything
else managed from happening:
public class TestLoop : ILoadNotificationPlugin
{
public bool Load()
{
EventConsumer con = new EventConsumer("all", "");
while (true)
{
Event ev = con.pop(0);
Log.WriteLine(LogLevel.Notice, "Event: " +
ev.serialized_string);
freeswitch.msleep(100);
}
}
}
However, if I fork off a thread here, freeswitch crashes:
public class TestLoop : ILoadNotificationPlugin
{
public bool Load()
{
ThreadPool.QueueUserWorkItem((o) =>
{
Log.WriteLine(LogLevel.Notice, "Thread Starting. ");
EventConsumer con = new EventConsumer("all", "");
while (true)
{
Event ev = con.pop(0);
Log.WriteLine(LogLevel.Notice, "Event: " +
ev.serialized_string);
freeswitch.msleep(100);
}
});
return true;
}
}
It doesn't look like this is a good place to start a long-running process?
Thanks!
Josh

[Freeswitch-users] Using mod_managed to create full FreeSWITCH modules
The wiki says: mod_managed exposes nearly the entire FreeSWITCH C API (courtesy of SWIG). This allows creation of not just API functions and call apps, but any type of module that FreeSWITCH supports (codecs, endpoints, etc.). The types are in the FreeSWITCH.Native namespace. FreeSWITCH.Native. The FreeSWITCH.Native.freeswitch type contains static members to access all the functions. Does anybody have a starting point they can share for a non-API/APP managed module. I'd like to build something that runs in the SWITCH_MODULE_SHUTDOWN_FUNCTION/SWITCH_MODULE_SHUTDOWN_FUNCTION/SWITCH_MODULE_SHUTDOWN_FUNCTION lifecycle. How can this be done? Thanks!

[Freeswitch-users] mod_managed ILoadNotificationPlugin
What is the purpose if the ILoadNotificationPlugin? I thought it could be used to start off background code, but code run from that point seems to be terminated when the method returns. Does it only exist to check dependencies? ___ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
Re: [Freeswitch-users] Subscribing to events in managed C# / .NET
Is there a way to start this when FreeSWITCH starts? The lua and perl
modules have a 'startup-script' configuration preference. Is there something
similar in mod_managed? Or is there a way to have an api command executed at
a startup?
Exactly what I was after - thank you!
