* - 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

* | - A warning is emitted if the ``isolation_level`` parameter is usedMike Bayer2015-02-041-8/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bayer2015-02-021-14/+18

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | improved in conjunction with loader directives such as :func:`.joinedload` and :func:`.contains_eager` such that if two :meth:`.PropComparator.of_type` modifiers of the same base type/path are encountered, they will be joined together into a single "polymorphic" entity, rather than replacing the entity of type A with the one of type B. E.g. a joinedload of ``A.b.of_type(BSub1)->BSub1.c`` combined with joinedload of ``A.b.of_type(BSub2)->BSub2.c`` will create a single joinedload of ``A.b.of_type((BSub1, BSub2)) -> BSub1.c, BSub2.c``, without the need for the ``with_polymorphic`` to be explicit in the query. fixes #3256

A warning is emitted when the old relationship is replaced, however if the mapping were already used for querying, the old relationship would still be referenced within some registries. fixes #3251
