[Zope-Checkins] CVS: Zope/lib/python/zExceptions - TracebackSupplement.py:1.1.2.1.34.1

[Tres Seaver]

Update of /cvs-repository/Zope/lib/python/zExceptions
In directory cvs.zope.org:/tmp/cvs-serv32028/lib/python/zExceptions

Modified Files:
      Tag: tseaver-hasattr_geddon-branch
	TracebackSupplement.py 
Log Message:

  - Removed all uses of the 'hasattr' builtin from the core, where
    the object being tested derives (or might) from Persistent.
    XXX:  currently, this branch imports a 'safe_hasattr' from ZODB.utils,
    which adds a dependency on ZODB for some packages;  we probably
    need a better location, and perhas a C implementation?
