* Improve serializer behaviorMike Bayer2017-03-141-0/+3
| | | | | | | | | | Fix an issue where the Annotated system needs to have a __reduce__ method, also see why we can't default to HIGHEST_PROTOCOL. This latter part might not be a good idea until 1.2 for compatibility reasons. Change-Id: I0239e38259fc768c9e3b6c448c29161e271a969c Fixes: #3918

| | | | | | | | | | :class:`.Query` and in other situations where selects or joins were aliased (such as joined table inheritance) could fail if a user-defined :class:`.Column` subclass were used in the expression. In this case, the subclass would fail to propagate ORM-specific "annotations" along needed by the adaptation. The "expression annotations" system has been corrected to account for this case.

* - A large refactoring of the ``sqlalchemy.sql`` package has reorganizedMike Bayer2013-08-121-0/+182
the import structure of many core modules. ``sqlalchemy.schema`` and ``sqlalchemy.types`` remain in the top-level package, but are now just lists of names that pull from within ``sqlalchemy.sql``. Their implementations are now broken out among ``sqlalchemy.sql.type_api``, ``sqlalchemy.sql.sqltypes``, ``sqlalchemy.sql.schema`` and ``sqlalchemy.sql.ddl``, the last of which was moved from ``sqlalchemy.engine``. ``sqlalchemy.sql.expression`` is also a namespace now which pulls implementations mostly from ``sqlalchemy.sql.elements``, ``sqlalchemy.sql.selectable``, and ``sqlalchemy.sql.dml``. Most of the "factory" functions used to create SQL expression objects have been moved to classmethods or constructors, which are exposed in ``sqlalchemy.sql.expression`` using a programmatic system. Care has been taken such that all the original import namespaces remain intact and there should be no impact on any existing applications. The rationale here was to break out these very large modules into smaller ones, provide more manageable lists of function names, to greatly reduce "import cycles" and clarify the up-front importing of names, and to remove the need for redundant functions and documentation throughout the expression package.
