* WINE RPC TODO's (and a few TODONT's)
*
* - widl is like MIDL for wine. For wine to be a useful RPC platform, quite
* a bit of work needs to be done here. widl currently doesn't generate stubs
* for RPC invocation -- it will need to; this is tricky because the MIDL compiler
* does some really weird stuff. Then again, we don't necessarily have to
* make widl work like MIDL, so it could be worse. Lately Ove has been working on
* some widl enhancements.
*
* - RPC has a quite featureful error handling mechanism; basically none of this is
* implemented right now.
*
* - There are several different memory allocation schemes for MSRPC.
* I don't even understand what they all are yet, much less have them
* properly implemented. Surely we are supposed to be doing something with
* the user-provided allocation/deallocation functions, but so far,
* I don't think we are doing this...
*
* - MSRPC provides impersonation capabilities which currently are not possible
* to implement in wine. At the very least we should implement the authorization
* API's & gracefully ignore the irrelevant stuff (to a small extent we already do).
*
* - Some transports are not yet implemented. The existing transport implementations
* are incomplete and many seem to be buggy
*
* - The various transports that we do support ought to be supported in a more
* object-oriented manner, like in DCE's RPC implementation, instead of cluttering
* up the code with conditionals like we do now.
*
* - Data marshalling: So far, only the very beginnings of an implementation
* exist in wine. NDR protocol itself is documented, but the MS API's to
* convert data-types in memory into NDR are not. This is a bit of a challenge,
* but it is at the top of Greg's queue and should be improving soon.
*
* - ORPC is RPC for OLE; once we have a working RPC framework, we can
* use it to implement out-of-process OLE client/server communications.
* ATM there is a 100% disconnect between the marshalling in the OLE DLL's
* and the marshalling going on here. This is a good thing, since marshalling
* doesn't work yet. But once it does, obviously there will be the opportunity
* to implement out-of-process OLE using wine's rpcrt4 or some derivative.
* This may require some collaboration between the RPC workers and the OLE
* workers, of course.
*
* - In-source API Documentation, at least for those functions which we have
* implemented, but preferably for everything we can document, would be nice.
* Some stuff is undocumented by Microsoft and we are guessing how to implement
* (in these cases we should document the behavior we implemented, or, if there
* is no implementation, at least hazard some kind of guess, and put a few
* question marks after it ;) ).
*
* - Stubs. Lots of stuff is defined in Microsoft's headers, including undocumented
* stuff. So let's make a stub-farm and populate it with as many rpcrt4 api's as
* we can stand, so people don't get unimplemented function exceptions.
*
* - Name services: this part hasn't even been started.
*
* - Concurrency: right now I have not tested more than one request at a time;
* we are supposed to be able to do this, and to queue requests which exceed the
* concurrency limit.
*
* - Protocol Towers: Totally unimplemented.... I think.
*
* - Context Handle Rundown: whatever that is.
*
* - Nested RPC's: Totally unimplemented.
*
* - Statistics: we are supposed to be keeping various counters. we aren't.
*
* - Connectionless RPC: unimplemented (DNE in win9x so not a top priority)
*
* - XML RPC: Dunno if microsoft does it... but we'd might as well just for kicks.
*
* - ...? More stuff I haven't thought of. If you think of more RPC todo's drop me
* an e-mail <gmturner007@ameritech.net> or send a patch to wine-patches.
