DCOM paper in lorikeet. This is the result of 1.5 months work (mainly
figuring out how things *really* work) at the end of 2004.
In general:
- Clearer distinction between COM and DCOM. DCOM is now merely
the glue between DCE/RPC+ORPC and COM. COM can also work without
DCOM now. This makes the code a lot clearer.
- Clearer distinction between NDR and DCOM. Before, NDR had a couple of
"if"s to cope with DCOM, which are now gone.
- Use "real" arguments rather then structures for function arguments in
COM, mainly because most of these calls are local so packing/unpacking
data for every call is too much overhead (both speed- and code-wise)
- Support several mechanisms to load class objects:
- from memory (e.g. part of the current executable, registered at start-up)
- from shared object files
- remotely
- Most things are now also named COM rather then DCOM because that's what it
really is. After an object is created, it no longer matters whether it
was created locally or remotely.
There is a very simple example class that contains
both a class factory and a class that implements the IStream interface.
It can be tested (locally only, remotely is broken at the moment)
by running the COM-SIMPLE smbtorture test.
Still to-do:
- Autogenerate parts of the class implementation code (using the coclass definitions in IDL)
- Test server-side
- Implement some of the common classes, add definitions for common interfaces.

less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a
huge change, as winbind_client.h was including system/filesys.h and
defining the old uint32 and uint16 types, as well as its own
pstring and fstring.

large commit. I thought this was worthwhile to get done for
consistency.

files don't need to match the type names in the generated headers
- with this type mapping we no longer need definitions for the
deprecated "int32", "uint8" etc form of types. We can now force
everyone to use the standard types int32_t, uint8_t etc.
- fixed all the code that used the deprecated types
- converted the IDL types "int64" and "uint64" to "dlong" and
"udlong". These are the 4 byte aligned 64 bit integers that
Microsoft internally define as two 32 bit integers in a
structure. After discussions with Ronnie Sahlberg we decided that
calling these "int64" was confusing, as it implied a true 8 byte
aligned type
- fixed all the cases where we incorrectly used things like
"NTTIME_hyper" in our C code. The generated API now uses a NTTIME for
those. The fact that it is hyper-aligned on the wire is not relevant
to the API, and should remain just a IDL property

- Work on server side and local COM support (should work, just no
example classes yet)
- Use vtables so that local and remote calls can be used transparently
- Generate 'proxies and stubs' rather then heavily modified code in client.pm and server.pm. proxies (client side code) are generated in proxy.pm, stubs (server side dispatchers) are generated in stubs.pm
- Support registering classes and interfaces
- DCOM interfaces no longer have to be in the same IDL file as their
base interface, which will allow us to split up dcom.idl

The thing that finally convinced me that minimal includes was worth
pursuing for rpc was a compiler (tcc) that failed to build Samba due
to reaching internal limits of the size of include files. Also the
fact that includes.h.gch was 16MB, which really seems excessive. This
patch brings it back to 12M, which is still too large, but
better. Note that this patch speeds up compile times for both the pch
and non-pch case.
This change also includes the addition iof a "depends()" option in our
IDL files, allowing you to specify that one IDL file depends on
another. This capability was needed for the auto-includes generation.
