[Python-Dev] No longer enable Py_TRACE_REFS by default in debug build (original) (raw)

If reducing the Python memory footprint is an argument for disabling PyTRACEREFS, it is a weak argument because there is larger overhead in the debug build.

I think what Victor is argueing is rather that we have better ways to debug memory problems these days, so we might be able to get rid of a relict that no-one is using (or should be using) anymore and that has its drawbacks (such as a very different ABI and higher memory load).

I don't really have an opinion here, but I can at least say that I never found a use case for Py_TRACE_REFS myself and therefore certainly wouldn't miss it.
