[Zodb-checkins] CVS: Zope2/lib/python/ZODB - Connection.py:1.56

[jeremy@digicool.com]

Update of /cvs-repository/Zope2/lib/python/ZODB
In directory korak.digicool.com:/tmp/cvs-serv8648

Modified Files:
	Connection.py 
Log Message:
Remove many unused default argument definitions used as speed optimizations.

Many methods had default arguments that were used to bind a global or
builtin name, like type, None, or type(''), as a local name.  In many
cases, the names bound were not referenced in the method body
(presumably they used to be referenced).

commit_sub(): In this one case, delete the default arg anyway, because
    it's only used once.
