  to get all flake8 passing

- Fixed a few edge cases which arise in the so-called "row switch"

2014-05-29T00:01:49+00:00

scenario, where an INSERT/DELETE can be turned into an UPDATE.
In this situation, a many-to-one relationship set to None, or
in some cases a scalar attribute set to None, may not be detected
as a net change in value, and therefore the UPDATE would not reset
what was on the previous row.   This is due to some as-yet
unresovled side effects of the way attribute history works in terms
of implicitly assuming None isn't really a "change" for a previously
un-set attribute.  See also :ticket:`3061`. fixes #3060

Detection of a primary key change within the process

of cascading a natural primary key update will succeed
even if the key is composite and only some of the
attributes have changed.

- move all of orm to use absolute imports

2012-06-23T18:45:47+00:00

- break out key mechanics of loading objects
into new "orm.loading" module, removing implementation
details from both mapper.py and query.py. is analogous
to persistence.py
- some other cleanup and old cruft removal
