6899	_QuerySet.__nonzero__ returns True for empty query sets with cached results	Brodie Rao	nobody	"Given any sort of model with zero instances/rows, the following will currently occur:
{{{
#!python
>>> objects = Foo.objects.all()
>>> bool(objects)
False
>>> bool(objects)
True
}}}

`_QuerySet.__nonzero__` unconditionally returns `True` when the result cache is populated, even if nothing is in the cache (i.e. there are no results).

I'm attaching a patch that fixes this behavior, and a test case for it."		closed	Database layer (models, ORM)	queryset-refactor		fixed	qs-rf		Accepted	1	0	0	0	0	0
