* - The Postgresql :class:`.postgresql.ENUM` type will emit aMike Bayer2015-03-111-16/+26
| | | | | | | | | | | | DROP TYPE instruction when a plain ``table.drop()`` is called, assuming the object is not associated directly with a :class:`.MetaData` object. In order to accomodate the use case of an enumerated type shared between multiple tables, the type should be associated directly with the :class:`.MetaData` object; in this case the type will only be created at the metadata level, or if created directly. The rules for create/drop of Postgresql enumerated types have been highly reworked in general. fixes #3319

| | | | | - test_schema_2 is only on PG and doesn't need a drop all, omit this for now - py3k has exception.args[0], not message
* - restate sort_tables in terms of a more fine grainedMike Bayer2015-01-011-37/+227
| | | | | | | | | | | | | sort_tables_and_constraints function. - The DDL generation system of :meth:`.MetaData.create_all` and :meth:`.Metadata.drop_all` has been enhanced to in most cases automatically handle the case of mutually dependent foreign key constraints; the need for the :paramref:`.ForeignKeyConstraint.use_alter` flag is greatly reduced. The system also works for constraints which aren't given a name up front; only in the case of DROP is a name required for at least one of the constraints involved in the cycle. fixes #3282

* - A large refactoring of the ``sqlalchemy.sql`` package has reorganizedMike Bayer2013-08-121-0/+826
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.
