I am trying to write an (optional!) C extension for SQLAlchemy, and I
am struggling to make an extension type picklable *and* using the same
format as the pure Python version (so that computers with the C
extension can unpickle pickles from computers without it and
vice-versa). [...]
My last hope is to define __reduce__ on the Python
side too,
That seems reasonable.
and make it use a module-level "reconstructor" function as
follow:
def mypythontype_reconstructor(cls, state):
obj = object.__new__(cls, state):
....
return obj
Will this work? Any other idea?
If you're going to call object.__new__(cls, state) anyway, then just
return the object's type as the first item in __reduce__; no need to
create such global function
