* WINE RPC TODO's (and a few TODONT's)
*
* - Ove's decreasingly incomplete widl is an IDL compiler for wine. For widl
* to be wine's only IDL compiler, a fair bit of work remains to be done.
* until then we have used some midl-generated stuff. (What?)
* widl currently doesn't generate stub/proxy files required by wine's (O)RPC
* capabilities -- nor does it make those lovely format strings :(
* The MS MIDL compiler does some really esoteric stuff. Of course Ove has
* started with the less esoteric stuff. There are also lots of nice
* comments in there if you want to flex your bison and help build this monster.
*
* - RPC has a quite featureful error handling mechanism; basically none of this is
* implemented right now. We also have deficiencies on the compiler side, where
* wine's __TRY / __EXCEPT / __FINALLY macros are not even used for RpcTryExcept & co,
* due to syntactic differences! (we can fix it with widl by using __TRY)
*
* - 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 an extent we already do).
*
* - Some transports are not yet implemented. The existing transport implementations
* are incomplete and may be bug-infested.
*
* - The various transports that we do support ought to be supported in a more
* object-oriented manner, as in DCE's RPC implementation, instead of cluttering
* up the code with conditionals like we do now.
*
* - Data marshalling: So far, only the beginnings of a full 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 challenging work,
* and has supposedly been "at the top of Greg's queue" for several months now.
*
* - 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 maybe a disconnect between the marshalling in the OLE DLL's
* and the marshalling going on here [TODO: well, is there or not?]
*
* - In-source API Documentation, at least for those functions which we have
* implemented, but preferably for everything we can document, would be nice,
* since some of this stuff is quite obscure.
*
* - Name services... [TODO: what about them]
*
* - 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.
*
* - Async RPC: Unimplemented.
*
* - XML/http RPC: Somewhere there's an XML fiend that wants to do this! Betcha
* we could use these as a transport for RPC's across computers without a
* permissions and/or licensing crisis.
*
* - The NT "ports" API, aka LPC. Greg claims this is on his radar. Might (or
* might not) enable users to get some kind of meaningful result out of
* NT-based native rpcrt4's. Commonly-used transport for self-to-self RPC's.
*
* - ...? 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 the
* wine-patches mailing list.
