Add Query.lazy_load_from attribute for sharding

2018-06-04T16:30:05+00:00

Added new attribute :attr:`.Query.lazy_loaded_from` which is populated
with an :class:`.InstanceState` that is using this :class:`.Query` in
order to lazy load a relationship.  The rationale for this is that
it serves as a hint for the horizontal sharding feature to use, such that
the identity token of the state can be used as the default identity token
to use for the query within id_chooser().

Also repaired an issue in the :meth:`.Result.with_post_criteria`
method added in I899808734458e25a023142c2c5bb37cbed869479
for :ticket:`4128` where the "unbake subquery loaders" version was calling
the post crtieria functions given the :class:`.Result` as the argument
rather than applying them to the :class:`.Query`.

Enable multi-level selectin polymorphic loading

selectin polymorphic loading

2017-06-05T15:27:00+00:00

Added a new style of mapper-level inheritance loading
"polymorphic selectin".  This style of loading
emits queries for each subclass in an inheritance
hierarchy subsequent to the load of the base
object type, using IN to specify the desired
primary key values.

Fixes: #3948

Allow metadata.reflect() to recover from unreflectable tables

2017-05-22T19:51:07+00:00

Added support for views that are unreflectable due to stale
table definitions, when calling :meth:`.MetaData.reflect`; a warning
is emitted for the table that cannot respond to ``DESCRIBE``
but the operation succeeds.  The MySQL dialect now
raises UnreflectableTableError which is in turn caught by
MetaData.reflect().  Reflecting the view standalone raises
this error directly.

Add safe_reraise() + warnings only to Connection._autorollback

2017-03-27T15:14:24+00:00

Added an exception handler that will warn for the "cause" exception on
Py2K when the "autorollback" feature of :class:`.Connection` itself
raises an exception. In Py3K, the two exceptions are naturally reported
by the interpreter as one occurring during the handling of the other.
This is continuing with the series of changes for rollback failure
handling that were last visited as part of :ticket:`2696` in 1.0.12.

Support hybrids/composites with bulk updates

2017-03-22T21:44:56+00:00

The :meth:`.Query.update` method can now accommodate both
hybrid attributes as well as composite attributes as a source
of the key to be placed in the SET clause.   For hybrids, an
additional decorator :meth:`.hybrid_property.update_expression`
is supplied for which the user supplies a tuple-returning function.
