* - sort of working, not saving on much, eager loading of courserow_proc_integration_2Mike Bayer2015-02-284-121/+105

|
* - OK this version not working for polymorphic or bundles yet,Mike Bayer2015-02-284-45/+97
| | | | | | but for large loads it ties master, for many short loads it is slightly faster. if the code can be made clearer then it's a win
* - wrong! I didn't have the cprocs on the master test. we are barelyMike Bayer2015-02-281-0/+5
| | | | | | | slower. we do save on single queries, however. - but...wrong! we still can't do this approach for eager loads. we don't have context.outer_adapter available when we set up "quick" here, so this can't work.

* - polymorphic loading, working very rudimentallyrow_proc_integrationMike Bayer2015-02-265-79/+173
| | | | | | | | | | | running orm2010, the whole approach adds callcounts. code is more complex, less reliable, pretty much a total bust. will try to see if create_row_processor can remain but be called against either "result" or a context namespace ahead of time, and if this somehow can be used to simplify the need to call upon strategy lookup twice.

| | | | | | | | | | many-to-one ``!= None`` would fail if the source were an aliased class, or if the query needed to apply special aliasing to the expression due to aliased joins or polymorphic querying; also fixed bug in the case where comparing a many-to-one to an object state would fail if the query needed to apply special aliasing due to aliased joins or polymorphic querying. fixes #3310

|
* - A warning is emitted when :func:`.cast` is used with the MySQLMike Bayer2015-02-093-29/+66
| | | | | | | | | | | 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 Bayer2015-02-055-77/+215
| | | | | | | | | | | | | | | | | | 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
* | - Fixed bug in :class:`.Connection` and pool where theMike Bayer2015-02-045-0/+41
| | | | | | | | | | | | | | | | | | :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 Bayer2015-02-049-15/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | - Fixed bug in lazy loading SQL construction whereby a complexMike Bayer2015-02-024-17/+101
| | | | | | | | | | | | | | | | primaryjoin that referred to the same "local" column multiple times in the "column that points to itself" style of self-referential join would not be substituted in all cases.

* | - Repaired support for Postgresql UUID types in conjunction withMike Bayer2015-02-013-9/+75
| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
