* - Added a new extension suite :mod:`sqlalchemy.ext.baked`. ThisMike Bayer2015-03-116-128/+207
| | | | | | | | simple but unusual system allows for a dramatic savings in Python overhead for the construction and processing of orm :class:`.Query` objects, from query construction up through rendering of a string SQL statement. fixes #3054
* - Added a new entry ``"entity"`` to the dictionaries returned byMike Bayer2015-03-111-2/+8
| | | | | | | | | :attr:`.Query.column_descriptions`. This refers to the primary ORM mapped class or aliased class that is referred to by the expression. Compared to the existing entry for ``"type"``, it will always be a mapped entity, even if extracted from a column expression, or None if the given expression is a pure core expression. references #3320
* - Added a new event suite :class:`.QueryEvents`. TheMike Bayer2015-03-102-5/+63
| | | | | | | | | | | :meth:`.QueryEvents.before_compile` event allows the creation of functions which may place additional modifications to :class:`.Query` objects before the construction of the SELECT statement. It is hoped that this event be made much more useful via the advent of a new inspection system that will allow for detailed modifications to be made against :class:`.Query` objects in an automated fashion. fixes #3317
* - The subquery wrapping which occurs when joined eager loadingMike Bayer2015-03-101-1/+1
| | | | | | | | | is used with a one-to-many query that also features LIMIT, OFFSET, or DISTINCT has been disabled in the case of a one-to-one relationship, that is a one-to-many with :paramref:`.relationship.uselist` set to False. This will produce more efficient queries in these cases. fixes #3249
* - Fixed bug where the session attachment error "object is alreadyMike Bayer2015-03-101-7/+7
| | | | | | | attached to session X" would fail to prevent the object from also being attached to the new session, in the case that execution continued after the error raise occurred. fixes #3301

* - squash-merge the final row_proc integration branch. this isMike Bayer2015-03-017-88/+152
| | | | | | | | | | | | | | | a much more modest outcome than what we started with. 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.
* - Fixed bugs in ORM object comparisons where comparison ofMike Bayer2015-02-201-3/+4
| | | | | | | | | | 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
* - remove the need for a recursive call hereMike Bayer2015-02-201-5/+12

* - Fixed bug where internal assertion would fail in the case whereMike Bayer2015-02-201-2/+5
| | | | | | | | an ``after_rollback()`` handler for a :class:`.Session` incorrectly adds state to that :class:`.Session` within the handler, and the task to warn and remove this state (established by :ticket:`2389`) attempts to proceed. fixes #3309
* - Mapped state internals have been reworked to allow for a 50% reductionMike Bayer2015-02-187-77/+149
| | | | | | | | in callcounts specific to the "expiration" of objects, as in the "auto expire" feature of :meth:`.Session.commit` and for :meth:`.Session.expire_all`, as well as in the "cleanup" step which occurs when object states are garbage collected. fixes #3307

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

This allows sessions that rely upon either customized :meth:`.Session.get_bind` schemes or "bound" metadata to work in all relevant cases. fixes #3227 fixes #3242 fixes #1326

* | | - The "wildcard" loader options, in particular the one set up byMike Bayer2015-01-134-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the :func:`.orm.load_only` option to cover all attributes not explicitly mentioned, now takes into account the superclasses of a given entity, if that entity is mapped with inheritance mapping, so that attribute names within the superclasses are also omitted from the load. Additionally, the polymorphic discriminator column is unconditionally included in the list, just in the same way that primary key columns are, so that even with load_only() set up, polymorphic loading of subtypes continues to function correctly. fixes #3287

This is typically only an issue on an interpreter like Pypy where the cursor isn't immediately GC'ed, and can in some circumstances lead to transactions/ locks being open longer than is desirable. fixes #3285
