In developing a cPickle module for IronPython that's as compatible as possible with CPython, these questions have come up:
- Where are object.__reduce__ and object.__reduce_ex__ defined, and how does copy_reg._reduce_ex fit into the picture? PEP 307 states that the default __reduce__ implementation for new-style classes implemented in Python is copy_reg._reduce. However, in Python 2.4.3 dir(copy_reg) indicates that it has no _reduce method. (Tangentially, is there a way to inspect a method_descriptor object to determine the function it's bound to?) - When the optional constructor argument is passed to copy_reg.pickle, where is it stored and how is it used by pickle? - What does copy_reg.constructor() do?
