Warnings for @declared_attr.cascading

2017-09-26T15:36:08+00:00

A warning is emitted if a subclass attempts to override an attribute
that was declared on a superclass using ``@declared_attr.cascading``
that the overridden attribute will be ignored. This use
case cannot be fully supported down to further subclasses without more
complex development efforts, so for consistency the "cascading" is
honored all the way down regardless of overriding attributes.

A warning is emitted if the ``@declared_attr.cascading`` attribute is
used with a special declarative name such as ``__tablename__``, as this
has no effect.

Ensure that documenation refers to the current inconsistency that
__tablename__ can be overridden by subclasses however
@declared_attr.cascading cannot.

Add multivalued insert context for defaults

2017-09-16T16:52:25+00:00

Added a new method :class:`.DefaultExecutionContext.current_parameters`
which is used within a function-based default value generator in
order to retrieve the current parameters being passed to the statement.
The new function differs from the ``.current_parameters`` attribute in
that it also provides for optional grouping of parameters that
correspond to a multi-valued "insert" construct.  Previously it was not
possible to identify the subset of parameters that were relevant to
the function call.

Add next(), next() to ResultProxy

2017-09-15T18:03:27+00:00

Added ``__next__()`` and ``next()`` methods to :class:`.ResultProxy`,
so that the ``next()`` builtin function works on the object directly.
:class:`.ResultProxy` has long had an ``__iter__()`` method which already
allows it to respond to the ``iter()`` builtin.   The implementation
for ``__iter__()`` is unchanged, as performance testing has indicated
that iteration using a ``__next__()`` method with ``StopIteration``
is about 20% slower in both Python 2.7 and 3.6.
