Added keyword arguments to the :meth:`.MutableList.sort` function so that a key function as well as the "reverse" keyword argument can be provided. Fixes: #5114 Change-Id: Iefb29e1ccadfad6ecba558ce575029307001b88e
Fixed bug where using ``copy.copy()`` or ``copy.deepcopy()`` on :class:`.MutableList` would cause the items within the list to be duplicated, due to an inconsistency in how Python pickle and copy both make use of ``__getstate__()`` and ``__setstate__()`` regarding lists. In order to resolve, a ``__reduce_ex__`` method had to be added to :class:`.MutableList`. In order to maintain backwards compatibility with existing pickles based on ``__getstate__()``, the ``__setstate__()`` method remains as well; the test suite asserts that pickles made against the old version of the class can still be deserialized by the pickle module. Also modified sqlalchemy.testing.util.picklers to return picklers all the way through pickle.HIGHEST_PROTOCOL. Fixes: #4603 Change-Id: I7f78b9cfb89d59a706248536c553dc5e1d987b88
Implemented a new feature whereby the :class:`.AliasedClass` construct can now be used as the target of a :func:`.relationship`. This allows the concept of "non primary mappers" to no longer be necessary, as the :class:`.AliasedClass` is much easier to configure and automatically inherits all the relationships of the mapped class, as well as preserves the ability for loader options to work normally. - introduce new name for mapped_table, "persist_selectable". this is the selectable that selects against the local mapper and its superclasses, but does not include columns local only to subclasses. - relationship gains "entity" which is the mapper or aliasedinsp. - clarfiy name "entity" vs. "query_entity" in loader strategies.

Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

Fixed bug where using :meth:`.Mutable.associate_with` or :meth:`.Mutable.as_mutable` in conjunction with a class that has non- primary mappers set up with alternatively-named attributes would produce an attribute error. Since non-primary mappers are not used for persistence, the mutable extension now excludes non-primary mappers from its instrumentation steps. Change-Id: I2630d9f771a171aece03181ccf9159885f68f25e Fixes: #4215
Fixed regression in :class:`.ARRAY` datatype caused by :ticket:`3964`, which is essentially the same issue as that of :ticket:`3832`, where column attachment events for :class:`.ARRAY` would not be invoked. This breaks the use case of using declarative mixins that declare a :class:`.Column` which makes use of :meth:`.MutableList.as_mutable`. Change-Id: If8c57615860883837f6cf72661e46180a77778c1 Fixes: #4141
Implemented in-place mutation operators ``__ior__``, ``__iand__``, ``__ixor__`` and ``__isub__`` for :class:`.mutable.MutableSet` and ``__iadd__`` for :class:`.mutable.MutableList` so that change events are fired off when these mutator methods are used to alter the collection. Change-Id: Ib357a96d3b06c5deb6b53eb304a8b9f1dc9e9ede Fixes: #3853
Added new event handler :meth:`.AttributeEvents.modified` which is triggered when the func:`.attributes.flag_modified` function is invoked, which is common when using the :mod:`sqlalchemy.ext.mutable` extension module. Change-Id: Ic152f1d5c53087d780b24ed7f1f1571527b9e8fc Fixes: #3303
Fixed regression released in 1.1.8 due to :ticket:`3950` where the deeper search for information about column types in the case of a "schema type" or a :class:`.TypeDecorator` would produce an attribute error if the mapping also contained a :obj:`.column_property`. Change-Id: I38254834d3d79c9b339289a8163eb4789ec4c931 Fixes: #3956
