Summary:	Valuetypes have call-by-reference semantics in collocated calls

Description Nanbor Wang 2002-12-06 20:40:27 CST

Valuetypes should always be passed by value.  However, TAO's collocated 
invocations pass valuetypes as references.  I.e., servants can change the 
passed in parameters in collocated invocations, which is wrong.  

Need to change the IDL compiler to create a copy for both ThruPOA and Direct 
proxies.

Looks like this bug depends on 1391.

Comment 2 Jeff Parsons 2002-12-15 12:51:42 CST

Accepted. Maybe Boris can work on this.

The test TAO\tests\OBV\Collocated\Forward is failing because of this problem. I 
see this for example on Solaris, MSVC6 and Borland. On some builds this tests 
runs without problems, strange however.

I believe it will be easier to fix this problem once bug 1369 is fixed.

Comment 5 Johnny Willemsen 2005-03-15 03:23:03 CST

I wonder if this is now easier to fix with all refactoring that is currently 
done. This test is still failing.

Comment 9 Johnny Willemsen 2006-12-05 09:49:38 CST

to pool again

Comment 10 Jeff Parsons 2006-12-06 11:05:47 CST

We are talking only about IN arguments, right? In all other cases, don't we 
want the arguments to change when the servant modifies them?
