Python development on 8th October

by Kushal Das

Use setUpClass() and tearDownClass() in test_multiprocessing.

Each manager test class now uses a separate manager. Also, process pools are no longer created before starting any tests.

Note that warnings are written if the manager for a test case still has live objects when it is shutdown. This is true for a few test cases which fail to wait for all child processes to end. Files changed: - Lib/test/test_multiprocessing.py

Make mp_main an alias for main in all processes to simplify pickling of classes defined in main module Files changed: - Lib/multiprocessing/init.py - Lib/multiprocessing/init.py
