DCOM and Google's Summer of Code
Hello! I'm in trouble trying to estimate effort needed to implement marshalling interoperable with MS. Is it a right task for 2-2.5 months of Google's "Summer of Code"? Best regards, Ivan Pechorin.

I think DCOM is way above student level. There might be some other tasks.
Marcus, thank you for realistic estimation. I'm interested to work on Wine's DCOM in a long term. Please, could you suggest some intermediate tasks?

There's a page we're writing here: http://wiki.winehq.com/SummerOfCode It might prove interesting. DCOM is stupidly hard, although that said I'm a student myself and Rob only recently stopped being a student. Raw RPC is a bit easier but still ... I think the ASP or theming tasks might be fun. Alternatively, maybe some Direct3D work?

Mike, I need Wine's DCOM implemented to port some complex app to Linux. Google's offer is just a reason to start working on it a bit earlier than I planned.

Ah, I see. If you are definitely going to work on it, then maybe Rob and myself should create a wiki page with all the work that needs to be done. At the moment much work remains to be done. For instance: * Make the RPC runtime compatible with Microsofts marshalling format/DCE * Possibly implement the necessary parts of widl * Implement the OXID resolver, a proper endpoint mapper, maybe a proper ROT * Implement complex/simple pinging * Maybe implement IRemoteActivation/ISystemActivator You may wish to work with or contract CodeWeavers to help you with this project. thanks -mike

DCOM is a much larger project requiring some degree of infrastructure work that would be difficult for a person new to the Wine codebase and new to COM. So DCOM is probably out of reach, but the underlying protocol, DCE/RPC is probably right for 2-2.5 months of work. The work will involve parsing MIDL format strings and marshaling/unmarshaling data correctly to/from a buffer. The project should be easier for a new, but bright coder who hasn't yet built up a knowledge of Win32 / POSIX APIs than many other projects. I could provide a test program that exercises and certain number of Ndr types and say "make this work". We could vary the number of types to vary the amount of work. -- Rob Shearman

Robert, thank you for clarification. I'm interested in Wine's DCOM in a long term because I have a big task: I need to port to Linux some complex commercial middleware and a couple of apps based on it. These apps employ DCOM heavily.

It will be very helpful if you provide this test program. Robert, thank you for accurate and clear definition of an intermediate goal.
