[NSWI080] Middleware Assignment 2

[Vlastimil Dort]

Dear students,

In reaction to questions some of you had about the second assignment:

1) Servant destruction

The C++11 mapping say less  than the old C++ mapping about destruction 
of servants that are no longer needed. In the old mapping, the servants 
keep an internal reference count, while in the new mapping, the type 
CORBA::servant_traits<T>::ref_type behaves like std::shared_ptr.

Keep in mind that when an object is activated, the POA will keep 
additional reference(s) to the servant. In order to allow the servant to 
be destroyed, it has to be deactivated first (using poa->deactivate_object).

2) Valgrind

If you use the Valgrind tool, you may encounter some values or messages 
reported, which are related to the ORB implementation rather than your 
code. This tool may be helpful for diagnosing memory problems, but 
cannot tell you if your code is correct or not, and you have to use your 
judgement in interpreting the output.
