[Python-checkins] CVS: python/dist/src/Lib/test test_bool.py,1.1,1.2

[Guido van Rossum]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv8192/Lib/test

Modified Files:
	test_bool.py 
Log Message:
Implement an idea by Paul Rubin:

Change pickling format for bools to use a backwards compatible
encoding.  This means you can pickle True or False on Python 2.3
and Python 2.2 or before will read it back as 1 or 0.  The code
used for pickling bools before would create pickles that could
not be read in previous Python versions.
