Update of /cvs-repository/Zope/lib/python/BTrees
In directory cvs.zope.org:/tmp/cvs-serv20512/lib/python/BTrees

Modified Files:
	BucketTemplate.c 
Log Message:
Collector #892:  Misleading error msg when initializing an OIBTree
from a dict with a float value.

Mapping_update():  This squashed errors raised by PyObject_SetItem(),
changing them to a "not a 2-tuple" TypeError instead.  Unclear why, since
2-tupleness was checked earlier.  Fixed by backporting part of the
ZODB4 BTree construction code, which doesn't have this problem.  Bonus:
it's faster now too.
