Facundo Batista <facu...@taniquetil.com.ar> added the comment: Making a copy of f_locals values to return a dictionary that doesn't hold references to the locals of the frame is not that simple (for me, at least):
- shallow copy: we'll return always a new dict, with the values being a copy of locals; this is simpler, but what about other objects that are referenced in in those values? For example, in locals exists a list A which holds a reference to object B; the new dict we return will have copy of A, but this copy will still reference B. - deep copy: we'll return a new dict with a deep copy of all values; this is safer, but what about memory? In any case, how we could do a deep copy here? calling Python's code copy.deepcopy()? I want to add a fourth option to JP's initial ones: - have other attribute, something like f_locals_weak that is a list of tuples [(name, value), ...], being the values a weak reference to the real locals. What do you think?
