P.S. I wouldn’t like to change too much Gnutella::Packets just for the sake of experimentation.

Are you referring to the changes  ( or kind of changes ) like the ones I proposed…

If so, I understand ;-) It is usually a tight rope walk…

It really all depends on the tests… Exhaustive unit test suite which will tell me right away if I broke something…

What about CppUnit? CppUnit is a beauty… I started to pull Caltiko code into a test harness, but thought I would ask here first…

Separating out classes, and putting Unit Tests in is not simple but gives you a greater understanding… ( I could run some complex method into gdb and experiment with various  input …)

I have a copy of Mike Feather’s book and used some of the techniques he proposes.. painful, yes but invaluable ;-)
