While working on #6784, I've looked at _pickle.c and found it quite... daunting: 6500 lines and 185kB. I have been working on a bit of cleanup, and I'd like some comments on this.
I'm working on adapting
_pickle.c into the following structure:
_pickle.c takes care of the module initialization
_pickle/*.c are helper files for this (global functions/definitions)
_pickle/PicklerObject contains all files that relate to the Pickler
class - initialization, all functions, etc, and
_pickle/PicklerObject/picklers/*.c contains all pickling functions,
split out into groups (corresponding to pickletools.StackObjects)
This should end in a tree where every .c module lists the relevant dependencies (and as such should be compilable on itself).
Currently, I'm at the point where PicklerObject roughly has the structure I want (although not every file is compilable on itself yet). As such, I feel this is the right moment to ask if it would be seen as an useful improvement in trunk, and to see if anyone has suggestions for improvements.
