Warn when declared_attr.cascading detected on mapped class

2017-06-06T21:16:58+00:00

A warning is emitted if the :attr:`.declared_attr.cascading` modifier
is used with a declarative attribute that is itself declared on
a class that is to be mapped, as opposed to a declarative mixin
class or ``__abstract__`` class.  The :attr:`.declared_attr.cascading`
modifier currently only applies to mixin/abstract classes.

Also add a test for @declared_attr.cascading when used on an attribute
on __abstract__.

Don't hard-evaluate non-ORM @declared_attr for AbstractConcreteBase

2017-05-26T17:28:15+00:00

Fixed bug where using :class:`.declared_attr` on an
:class:`.AbstractConcreteBase` where a particular return value were some
non-mapped symbol, including ``None``, would cause the attribute
to hard-evaluate just once and store the value to the object
dictionary, not allowing it to invoke for subclasses.   This behavior
is normal when :class:`.declared_attr` is on a mapped class, and
does not occur on a mixin or abstract class.  Since
:class:`.AbstractConcreteBase` is both "abstract" and actually
"mapped", a special exception case is made here so that the
"abstract" behavior takes precedence for :class:`.declared_attr`.

Protect against cls weakref becoming None

2017-05-08T22:36:57+00:00

Protected against testing "None" as a class in the case where
declarative classes are being garbage collected and new
automap prepare() operations are taking place concurrently, very
infrequently hitting a weakref that has not been fully acted upon
after gc.

Union the exclude_properties of the inheriting mapper in declarative

2017-01-30T22:28:22+00:00

Fixed bug where the "automatic exclude" feature of declarative that
ensures a column local to a single table inheritance subclass does
not appear as an attribute on other derivations of the base would
not take effect for multiple levels of subclassing from the base.

Support python3.6

Corrects some warnings and adds tox config.  Adds DeprecationWarning
to the error category.   Large sweep for string literals w/ backslashes
as this is common in docstrings

Remove some legacy dead code from the declared_attr logic

2016-10-16T14:45:54+00:00

The second 'if' condition was never called because the original
condition always returns.
