* - start trying to move things into __slots__. This seems to reduce theslotsMike Bayer2015-01-0411-96/+132
| | | | | size of the many per-column objects we're hitting, but somehow the overall memory is hardly being reduced at all in initial testing
* - use a different bitwise approach here that doesn't require iteratingMike Bayer2015-01-033-6/+16
| | | | through all possible set values
* - The :class:`.mysql.SET` type has been overhauled to no longerMike Bayer2015-01-032-51/+116
| | | | | | | | | | | | | | assume that the empty string, or a set with a single empty string value, is in fact a set with a single empty string; instead, this is by default treated as the empty set. In order to handle persistence of a :class:`.mysql.SET` that actually wants to include the blank value ``''`` as a legitimate value, a new bitwise operational mode is added which is enabled by the :paramref:`.mysql.SET.retrieve_as_bitwise` flag, which will persist and retrieve values unambiguously using their bitflag positioning. Storage and retrieval of unicode values for driver configurations that aren't converting unicode natively is also repaired. fixes #3283
* - tighten the inspection in _ColumnEntity to reduce unnecessaryMike Bayer2015-01-031-14/+14

* - test failures:Mike Bayer2015-01-022-2/+1
| | | | | - 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
* - repair drop_all_tablesMike Bayer2015-01-021-1/+1
|
* - restate sort_tables in terms of a more fine grainedMike Bayer2015-01-0110-75/+441
| | | | | | | | | | | | | 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
* - Added a new accessor :attr:`.Table.foreign_key_constraints`Mike Bayer2015-01-011-0/+27
| | | | | to complement the :attr:`.Table.foreign_keys` collection, as well as :attr:`.ForeignKeyConstraint.referred_table`.

| | | | | | | | | | | | | | VARBINARY(max) for large text/binary types. The MSSQL dialect will now respect this based on version detection, as well as the new ``deprecate_large_types`` flag. fixes #3039

| * - The SQLite dialect, when using the :class:`.sqlite.DATE`,Mike Bayer2014-12-051-1/+59
| | | | | | | | | | | | | | | | | | | | | | | | :class:`.sqlite.TIME`, or :class:`.sqlite.DATETIME` types, and given a ``storage_format`` that only renders numbers, will render the types in DDL as ``DATE_CHAR``, ``TIME_CHAR``, and ``DATETIME_CHAR``, so that despite the lack of alpha characters in the values, the column will still deliver the "text affinity". Normally this is not needed, as the textual values within the default storage formats already imply text. fixes #3257

| * - The engine-level error handling and wrapping routines will nowMike Bayer2014-12-055-18/+93
| | | | | | | | | | | | | | | | | | take effect in all engine connection use cases, including when user-custom connect routines are used via the :paramref:`.create_engine.creator` parameter, as well as when the :class:`.Connection` encounters a connection error on revalidation. fixes #3266
| * - New Oracle DDL features for tables, indexes: COMPRESS, BITMAP.Mike Bayer2014-12-042-10/+165

| * - Added support for CTEs under Oracle. This includes some tweaksMike Bayer2014-12-044-61/+138
| | | | | | | | | | | | | | to the aliasing syntax, as well as a new CTE feature :meth:`.CTE.suffix_with`, which is useful for adding in special Oracle-specific directives to the CTE. fixes #3220
| * - Updated the "supports_unicode_statements" flag to True for MySQLdbMike Bayer2014-12-042-3/+2
| | | | | | | | | | | | | | | | | | and Pymysql under Python 2. This refers to the SQL statements themselves, not the parameters, and affects issues such as table and column names using non-ASCII characters. These drivers both appear to support Python 2 Unicode objects without issue in modern versions. fixes #3121
| * - The :meth:`.Operators.match` operator is now handled such that theMike Bayer2014-12-048-9/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | return type is not strictly assumed to be boolean; it now returns a :class:`.Boolean` subclass called :class:`.MatchType`. The type will still produce boolean behavior when used in Python expressions, however the dialect can override its behavior at result time. In the case of MySQL, while the MATCH operator is typically used in a boolean context within an expression, if one actually queries for the value of a match expression, a floating point value is returned; this value is not compatible with SQLAlchemy's C-based boolean processor, so MySQL's result-set behavior now follows that of the :class:`.Float` type. A new operator object ``notmatch_op`` is also added to better allow dialects to define the negation of a match operation. fixes #3263
| * - The :meth:`.PGDialect.has_table` method will now query againstMike Bayer2014-12-042-1/+6
| | | | | | | | | | | | | | | | | | | | | | ``pg_catalog.pg_table_is_visible(c.oid)``, rather than testing for an exact schema match, when the schema name is None; this so that the method will also illustrate that temporary tables are present. Note that this is a behavioral change, as Postgresql allows a non-temporary table to silently overwrite an existing temporary table of the same name, so this changes the behavior of ``checkfirst`` in that unusual scenario. fixes #3264
