| * | | | Make pg8000 version detection more robustTony Locke2014-12-161-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pg8000 uses Versioneer, which means that development versions have version strings that don't fit into the dotted triple number format. Released versions will always fit the triple format though.
| * | | | pg8000 client_encoding in create_engine()Tony Locke2014-12-161-7/+54
| | | | | | | | | | | | | | | | | | | | | | | | | The pg8000 dialect now supports the setting of the PostgreSQL parameter client_encoding from create_engine().

The work of create_row_processor() for ColumnProperty objects is essentially done at query setup time combined with some lookups in _instance_processor(). - to allow this change for deferred columns, deferred columns no longer search for themselves in the result. If they've been set up as deferred without any explicit directive to undefer them, then this is what was asked for. if we don't do this, then we're stuck with this performance penalty for all deferred columns which in the vast majority of typical use cases (e.g. loading large, legacy tables or tables with many/large very seldom used values) won't be present in the result and won't be accessed at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subclass, the value returned by the descriptor is not available because the superclass is already mapped with the InstrumentedAttribute, until the subclass is mapped. We add a setattr() to set up that attribute so that the __mapper_args__ hook and possibly others have access to the "cascaded" version of the attribute within the call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dialect on a type where MySQL does not support CAST; MySQL only supports CAST on a subset of datatypes. SQLAlchemy has for a long time just omitted the CAST for unsupported types in the case of MySQL. While we don't want to change this now, we emit a warning to show that it's taken place. A warning is also emitted when a CAST is used with an older MySQL version (< 4) that doesn't support CAST at all, it's skipped in this case as well. fixes #3237

* | | | - The MySQL dialect now renders TIMESTAMP with NULL / NOT NULL inMike Bayer2015-02-051-48/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | all cases, so that MySQL 5.6.6 with the ``explicit_defaults_for_timestamp`` flag enabled will will allow TIMESTAMP to continue to work as expected when ``nullable=False``. Existing applications are unaffected as SQLAlchemy has always emitted NULL for a TIMESTAMP column that is ``nullable=True``. fixes #3155

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | :meth:`.Connection.invalidate` method, or an invalidation due to a database disconnect, would fail if the ``isolation_level`` parameter had been used with :meth:`.Connection.execution_options`; the "finalizer" that resets the isolation level would be called on the no longer opened connection. fixes #3302
* | | | - A warning is emitted if the ``isolation_level`` parameter is usedMike Bayer2015-02-044-8/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with :meth:`.Connection.execution_options` when a :class:`.Transaction` is in play; DBAPIs and/or SQLAlchemy dialects such as psycopg2, MySQLdb may implicitly rollback or commit the transaction, or not change the setting til next transaction, so this is never safe. - Added new parameter :paramref:`.Session.connection.execution_options` which may be used to set up execution options on a :class:`.Connection` when it is first checked out, before the transaction has begun. This is used to set up options such as isolation level on the connection before the transaction starts. - added new documentation section detailing best practices for setting transaction isolation with sessions. fixes #3296

* | | | - Repaired support for Postgresql UUID types in conjunction withMike Bayer2015-02-011-3/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the ARRAY type when using psycopg2. The psycopg2 dialect now employs use of the psycopg2.extras.register_uuid() hook so that UUID values are always passed to/from the DBAPI as UUID() objects. The :paramref:`.UUID.as_uuid` flag is still honored, except with psycopg2 we need to convert returned UUID objects back into strings when this is disabled. fixes #2940
* | | | - Added support for the :class:`postgresql.JSONB` datatype whenMike Bayer2015-01-311-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | using psycopg2 2.5.4 or greater, which features native conversion of JSONB data so that SQLAlchemy's converters must be disabled; additionally, the newly added psycopg2 extension ``extras.register_default_jsonb`` is used to establish a JSON deserializer passed to the dialect via the ``json_deserializer`` argument. Also repaired the Postgresql integration tests which weren't actually round-tripping the JSONB type as opposed to the JSON type. Pull request courtesy Mateusz Susik. - Repaired the use of the "array_oid" flag when registering the HSTORE type with older psycopg2 versions < 2.4.3, which does not support this flag, as well as use of the native json serializer hook "register_default_json" with user-defined ``json_deserializer`` on psycopg2 versions < 2.5, which does not include native json.

Additionally, naming conventions for check constraints that don't include the ``%(constraint_name)s`` token will now work for :class:`.SchemaType`- generated constraints, such as those of :class:`.Boolean` and :class:`.Enum`; this stopped working in 0.9.7 due to :ticket:`3067`. fixes #3299

Also repaired support for column type via FK transmission in a similar way when target columns had a different key and were referenced using link_to_name. fixes #3298

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | consists mainly of adjusting fixtures to ensure connections are closed explicitly. psycopg2cffi also handles unicode bind parameter names differently than psycopg2, and seems to possibly have a little less control over floating point values at least in one test which is marked as a "fail", though will see if it runs differently on linux than osx.. - changelog for psycopg2cffi, fixes #3052

In particular we are removing post_insert() which doesn't appear to be used based on a survey of prominent third party dialects.

Any visit method that accepts keyword arguments (e.g. ``**kw``) will in most cases receive a keyword argument ``type_expression``, referring to the expression object that the type is contained within. For columns in DDL, the dialect's compiler class may need to alter its ``get_column_specification()`` method to support this as well. The ``UserDefinedType.get_col_spec()`` method will also receive ``type_expression`` if it provides ``**kw`` in its argument signature. fixes #3074
