I now agree. > Yes I'm happy to start putting an exception based error propagation together. Thanks very much for being willing to actively lead this effort. > Perhaps it would be good for Hazen and Alan to start looking in more detail at implementing the error code propagation? If there are tools to help with that, then maybe it will be easier than I suspect. I am now confident of the return code method because of the 'warn_unused_result' gcc attribute capability, but let's not even start the substantial work required for this alternative unless it is made necessary because you run into some showstopper issue with the C exception-based alternative. > I started putting a plmalloc and similar set of functions together today. I'll drop those round for comments asap. Good idea, and I look forward to seeing what you come up with for the design of plmalloc and similar. Also, I would be happy to help propagate the use of plmalloc and similar throughout our code base immediately in this release cycle thus effectively getting rid of all those cases where we have previously been lazy about checking for memory allocation errors.
