[Mono-dev] removing schema:import with empty namespace
Hello Lluis, The attached WS produces wsdl with empty namespace in schema:import declaration. This causes problems in consumption of this wsdl by MS wsdl tool. The attached diff fixes that (by simple removing of imports with empty namespaces). Please review.

[Mono-dev] XSP null reference exception
I had XSP running for a bit then I got a call saying the site was unresponsive, I tried it myself and yeah it was like it would accept the socket but do nothing with the new connection. I looked at the XSP windows and found the output below: Unhandled Exception: System.NullReferenceException: A null value was found where an object instance was required. in 0x0 unknown method in (wrapper managed-to-native) System.Object:__icall_wrapper_mono_ldvirtfn (object,intptr) in 0x002ad Mono.WebServer.ApplicationServer:RunServer () in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void () I dont know what caused it, and don't know if its reproducible, I have been running that same site with a pretty high load for a few weeks now and never saw that error before, right now it actually had almost no load. I am on 1.1.9.2 on that machine on gentoo 64bit but will be upgrading to 1.1.10 this afternoon. --Carlos ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
RE: [Mono-dev] COM Interop in Mono
First, thanks a ton to Jonathan Pryor, Paolo Molaro, and Lluis Sanchez (and any others) for their help. So, previously I was able to create a class from an interop assembly and use that class in managed (casting, calling methods, etc. successfully interacting with the underlying COM object). That was only for COM objects whose coclass metadata was defined in the interop assembly. Now, arbitrary COM interfaces can be handled, even if the object is not a coclass or if the coclass is not defined in the interop assembly. In other words, a COM interface can be marshaled back to managed as long as that interface is defined in an interop assembly. I'll described the process (I'll post code later, it's too ugly right now as I just got it working). It begins with a method/property returning a parameter/value that is marked to be marshalled as an interface (meaning COM interface). This will invoke the marshaller. At this point, all that is assumed is that the pointer is a COM interface. The managed method has a target interface for the pointer. This target interface is queried for a GuidAttribute. The guid is then used to call QueryInterface on the underlying COM object to verify that the object does indeed support that interface. I created new class, ComProxy, that derives from RealProxy. An instance of ComProxy is created for type System.__ComObject, and the COM interface pointer is stored in the ComProxy object in an IntPtr field. Next, GetTransparentProxy is called on the ComProxy object. This transparent proxy is then cast to the target interface. ComProxy also implements System.Runtime.Remoting.IRemotingTypeInfo, which has a method CanCastTo. This method is called the first time the transparent proxy is cast to a new type. In this method, it is verified that the underlying COM object supports an interface via the method mentioned previously (calling QI with the interface GUID). If a cast can proceed, then special logic occurs because the object is a transparent proxy. The interface is added to the interface table, and the additional methods are added to the vtable. Normally, these vtable slots are filled with trampolines for remoting calls. However, in the COM case I emit trampolines that call the underlying COM object. So, much is done yet much remains ;-). If anyone has any questions please ask. TODO: 1. A lot of marshalling code. Currently, the System.Object type is not marshalled at all. This needs implemented for VARIANT, IUnknown, and IDispatch types. 2. Currently I'm not even going through the default marshalling code. I need to use this and adjust it for COM rules rather than pinvoke rules when using COM Interop. 3. Add finalizer logic so that COM objects will be released during finalization. Need to look into the thread issues with this, as finalization may not occur on the thread that the COM object was created on. 4. Right now, I store the IUnknown pointer. I really need an array/list of pointers that are indexed by interface. Thus, I only need to QueryInterface for each interface once. I do it on every method call currently. 5. Try this with XPCOM, or a cross platform COM solution. 6. Connection points/events. 7.

Should that not be included at this point, or should it be put inside of an #ifdef? On #mono there was some concern about different levels of support across platforms. Also, if I leave this inside of mono for now, any advice on that? Should I stick all my routines at the bottom of the file for example, or tag them all with a comment, etc.?

I don't think this stuff should be moved to a library, at least not until it's windows-only.

[Mono-dev] Interop question, C++ string marshaling
Hi all, is there standard way of C++ string marshaling. I'm trying to write wrapper of the C++ library in C#. And what is the best recommended way to do such wrapping in Mono if I have library in C++? Is it better to export everything as the C structures + functions with extern C__declspec(dllexport ) or classes are also supported quite well? (the finalcode should be clean and easy readable and portable of course). What is Is it better to use StdCall or Cdecl? I started with Cdecl but later did not manage to make callback work wit Cdecl here: typedef void (__stdcall *LogHandler) ( const char *message);static LogHandler log_handler = 0; I plan to make all interface C++ / C# code to be generatable, could you please point me for some some good recommented examples of using SWIG or similar library for such C# = C++ interops which are implemented? Thanks in advance, --Gena ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
