Program to crash remote object. (1.15 KB, text/plain) 2002-09-23 15:36 UTC, James Henstridge	Details

Description James Henstridge 2002-09-23 01:22:23 UTC

I was trying to get my Python ORBit bindings to generate stubs in cases
where the corresponding typelibs have not been initialised.  I did this by
trying to get the interface def with ORBit_small_get_iinterface().

Unfortunately, when doing this on a remote object, they seem to die.  (I
killed my panel a few times, for instance).  I assume this isn't supposed
to be possible ...

Comment 1 James Henstridge 2002-09-23 01:42:11 UTC

Just for the record, I would expect the fucntion to return NULL/raise
an exception if it couldn't fullfil the request.  Not crash the remote
object.

Comment 2 James Henstridge 2002-09-23 15:35:39 UTC

Here is a sample trace from the echo-server example program in ORBit2.
 The test program (which I will attach shortly) was run with the IOR
of the echo server as an argument.
