[Zope3-checkins] CVS: Zope3/src/zope/security - checker.py:1.36

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/security
In directory cvs.zope.org:/tmp/cvs-serv13692/zope/security

Modified Files:
	checker.py 
Log Message:
When iterating over security-proxied sequences, Python failed to
recognize a ForbiddenAttributeError as an AttributeError. To work
around this, we now don't raise a ForbiddenAttribute for __iter__ if
the object doesn't have an __iter__ attribute.
