r76499 - in python/trunk: Lib/test/pickletester.py Modules/cPickle.c
|
|
Author: alexandre.vassalotti
Date: Tue Nov 24 18:53:23 2009
New Revision: 76499
Log:
Issue 7128: Removed reference to the non-existent copyreg module.
The reference to copyreg was a unnoticed leftover from the compatibility
support for the grand renaming of the standard library in Python 3. The
compatibility support was reverted in r63493, but not completely as this
patch shows.
Based on a patch by Amaury Forgeot d'Arc.
