cpython-withatomic / Lib / _compat_pickle.py

# This module is used to map the old Python 2 names to the new names used in
# Python 3 for the pickle module.  This needed to make pickle streams
# generated with Python 2 loadable by Python 3.

# This is a copy of lib2to3.fixes.fix_imports.MAPPING.  We cannot import
# lib2to3 and use the mapping defined there, because lib2to3 uses pickle.
# Thus, this could cause the module to be imported recursively.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
