Issue 5665: name disambiguation for AMI interface & poller names is confusing (corba-rtf)
Source: Floorboard Software (Mr. Jonathan Biggar, jon@floorboard.com)
Nature: Uncategorized Issue
Severity: 
Summary: The rule for generating a unique AMI_ callback or poller name is to
stuff additional "AMI_" strings until the name is unique.  However,
consider the following IDL:


// IDL
module M {


    interface A {
    };


    interface AMI_A {
    };


};


this apparently maps to the implied IDL:


// implied IDL
module M {


    interface A {
    };


    interface AMI_AMI_A { // callback interface for A
    };


    interface AMI_A {
    };


    interface AMI_AMI_AMI_A {  // callback interface for AMI_A
    };
};



however, if I switch the order of declaration of A and AMI_A, the names
of the associated callback interfaces change.


Not only that, but if I split the IDL into two files:



// File 1
module M {


    interface A {
    };
};


// File 2
module M {
    interface AMI_A {
    };


};


and try to compile them separately, the generated code will fail.


I don't think there is any solution to this problem other than to
declare it an error to use an IDL identifier that begins with "AMI_" if
it causes a name clash.


The same problem applies to the AMI poller valuetypes.

Resolution: Resolution: Insert the requirement that any IDL that is meant to be used for AMI should not have any
Revised Text: In formal/02-06-01 make the following changes: 

In section 22.6 insert the following paragraph immediately following the first paragraph: 

" Due to the way in which identifier names are generated in the implied IDL, in order to avoid name clashes, any IDL that is meant to be used with Asynchronous Messaging must not contain any identifiers that have the string "AMI_" as a prefix."

I would simply reserve all identifiers that begin with AMI --
that's the cleanest solution.


Cheers,

The following resolution will appear in a vote in the near future if
there is no serious technical objection to it.
