_compat_pickle.py (8749B)


  1. # This module is used to map the old Python 2 names to the new names used in
  2. # Python 3 for the pickle module. This needed to make pickle streams
  3. # generated with Python 2 loadable by Python 3.
  4. # This is a copy of lib2to3.fixes.fix_imports.MAPPING. We cannot import
  5. # lib2to3 and use the mapping defined there, because lib2to3 uses pickle.
  6. # Thus, this could cause the module to be imported recursively.
