attempt number one, doesn't detect though if the label in the order by is not directly present there.
still not locating more nested expressions, may need to match on name
magic accessors to the rescue
- some tweaks to try to help out mssql+pyodbc support a bit, py3k is really
not happening too well (I need to stick with linux + freetds 0.91, I know)
Merge branch 'master' into ticket_1068
test tweak
- fdb is now official, [ticket:2504]
- restore the rollback cleanup handler, pg8000 is mostly obsolete
as a dialect and the firebird drivers need it
Merge branch 'master' into ticket_1068
- add changelog/migration note
- inline the label check
- remove the ``__iter__()`` with notimplemented since it interferes
with legitimate iterable detection, [ticket:2726]
Fixed bug whereby using :meth:`.MetaData.reflect` across a remote
schema as well as a local schema could produce wrong results
in the case where both schemas had a table of the same name.
[ticket:2728]
Fixed bug whereby joining a select() of a table "A" with multiple
foreign key paths to a table "B", to that table "B", would fail
to produce the "ambiguous join condition" error that would be
reported if you join table "A" directly to "B"; it would instead
produce a join condition with multiple criteria.
[ticket:2738]
- clean up some of the requires for cross-schema reflection
- add oracle profile counts
Fixed bug where :class:`.MutableDict` didn't report a change event
when ``clear()`` was called.
[ticket:2730]
The ``deferrable`` keyword argument on :class:`.ForeignKey` and
:class:`.ForeignKeyConstraint` will not render the ``DEFERRABLE`` keyword
on the MySQL dialect.  For a long time we left this in place because
a non-deferrable foreign key would act very differently than a deferrable
one, but some environments just disable FKs on MySQL, so we'll be less
opinionated here. [ticket:2721]
