[Mono-list] Unload AppDomain containing GTK Window

[Adrian Stern]

Hello

Since the Flashplugin is not very stable and on top of that leaks memory in long term use we try to run this critical part in a seperate AppDomain.
While creating and interacting with this window works fine, unloading the updomain causes the whole app to crash.

Since the unload works when i remove the Gtk.Window from the marshal object i can confirm this problem to be Gtk related (GTK Sharp)
Run on Ubuntu 11.4 and 12.4. This Bug seems to be known since 2004.

Running this sample every x seconds (loop) should just open a new window every x seconds while closing and destroying the other.

Any idey how i could accomplish this?

What i do:
#################################################
##### Class to run in other AppDomain and ist proxy class
#################################################

public class Fanta
{
  string s;

 // commenting this line out will cause the example to work!
  Gtk.Window w = new Gtk.Window(Gtk.WindowType.Toplevel);

  public Fanta(){ s = "blubb"; }

  public void echoS(){ Console.WriteLine( s );}
}

public class FantaProxy : MarshalByRefObject
{
  Fanta f = new Fanta();

  public void echoS(){
    f.GetType().InvokeMember("echoS", BindingFlags.InvokeMethod, null, f, null );
  }
}

#################################################
##### Code which causes the app to exit
#################################################

// d is a gobal AppDomain
// fp is FantaProxy  Type (also global)

d = AppDomain.CreateDomain( "FantaD");
string currentAssemblyPath = Assembly.GetExecutingAssembly().Location;
fp = d.CreateInstanceFromAndUnwrap( currentAssemblyPath, "AppDomainTest.FantaProxy" ) as FantaProxy;
fp.echoS();
AppDomain.Unload( d );
