Description calabrese_p 2003-09-11 12:33:01 CDT 
There are a couple of changes to the mapping of Local Objects in the latest
version of the C++ specification (see ptc/03-03-10 for details - the spec is not
yet approved).

These can be summarized as:
  - CORBA::LocalObject now includes reference counting by default
  - The IDL compiler will generate appropriate conversion operations 
    to allow a pointer to a local object implementation to be 
    automatically converted to the corresponding _ptr or _var type.

Accept for tao-support
Comment 2 Ossama Othman 2004-09-21 13:35:25 CDT 
FYI, the reference counting change didn't make it into the latest C++ mapping
(03-06-03) that came 3 months after the mentioned draft (03-03-10).

I didn't see anything about the conversion operators in the latest C++ mapping
either.  Can someone please confirm?

Given these circumstances, I don't think that this bug should block bug 1278. 
In any case, this issue is orthogonal to CORBA 3.0.x conformance since it is a
C++ mapping issue, not a core CORBA spec issue.
Comment 3 calabrese_p 2004-09-21 14:23:26 CDT 
Note that the draft of 03-03-10 is actually subsequent to the approved spec
03-06-03.  I don't know where it stands in the approval process.  I had these
same questions a year ago and Jonathan Biggar explained it to me and assured me
that the new draft would eventually become an approved specification.  Now I
suspect it is stalled and/or forgotten.

I agree there is no dependency on the CORBA 3.0 spec/features.

Hi Paul,

I'm under the impression that the document numbers are in the format
year-month-number.  If that is the case, the document numbers indicate that the
latest C++ mapping was adopted 3 months after the draft (i.e. 2003 June document
3 versus 2003 March document 10).

In any case, I'm sure you're right about what's supposed to be going in the C++
mapping.  Hopefully, the new mapping will be much cleaner than the existing one.
Comment 5 Johnny Willemsen 2006-02-13 05:00:52 CST 
this still doesn't seem to be changed n the c++ mapping. Shouldn't we now close
this bug?
Comment 6 Johnny Willemsen 2006-02-13 12:49:31 CST 
Paul mailed the link below, a vary recent draft
 http://www.omg.org/docs/smsc/06-01-01.pdf
Comment 7 Johnny Willemsen 2006-06-09 03:35:12 CDT 
1.2 C++ mapping still isn't formal
Comment 8 Johnny Willemsen 2007-05-01 06:37:55 CDT 
changed to enhancement and updated version.
Comment 9 Johnny Willemsen 2008-04-02 02:48:17 CDT 
spec is now foraml, so we can implement this and it is now a bug because we are now not compliant to the c++ mapping
Comment 10 Johnny Willemsen 2008-04-24 09:29:17 CDT 
partly implemented, also noticed that CORBA::Object doesn't have add_ref/remove_ref, that is in localobject, we need to change CORBA::Object also to match the spec
