problem with the generated skel-impl.c created 'destroy' fn.

["rajesh mirkhelkar" <rajmirk hotmail com>]

Hi,
I was trying to destroy the servant at the server end by calling the
function impl_module_object__destroy function. It still doesn't
destroy the servant ( i think ). The function
CORBA_Object_non_existent ((CORBA_Object)obj, ev) still returns FALSE.
after the destroy has been called.

After this when the client makes another query, it just hangs. (The client 
doesn't attempt to rebind to the stale IOR. If it does,
as expected, string_to_object(stale IOR) function fails).

Is this an ORBit bug. This question has been asked earlier too but no 
answers came forth.

Hi,

I just tested this with the "echo-server" and the "echo-client IOR_of_Server 
10000" and took the server down while the client was running. The client 
just hangs without any error message.

Looking at the CORBA 2.3 spec (The Standard Exceptions are described in more 
detail here) there should be either an OBJECT_NOT_EXIST exception when the 
server was not available anymore before sending the request and a TRANSIENT 
exception if the server died after the request has beend sent.

I guess that in the latter case there must be some kind of timeout to detect 
this kind of problem.. ?

Am I right, and if yes, is this a known problem with ORBit 0.5.x ??
