Add with_for_update() support in session.refresh()

2017-05-24T20:23:56+00:00

Session.refresh() is still hardcoded to legacy lockmode,
come up with a new API so that the newer argument style
works with it.

Added new argument :paramref:`.with_for_update` to the
:meth:`.Session.refresh` method.  When the :meth:`.Query.with_lockmode`
method were deprecated in favor of :meth:`.Query.with_for_update`,
the :meth:`.Session.refresh` method was never updated to reflect
the new option.

Add new configuration, inspection for baked queries

2017-05-17T21:08:23+00:00

Added new flag :paramref:`.Session.enable_baked_queries` to the
:class:`.Session` to allow baked queries to be disabled
session-wide, reducing memory use.   Also added new :class:`.Bakery`
wrapper so that the bakery returned by :paramref:`.BakedQuery.bakery`
can be inspected.

Emit after_rollback() event before snapshot removal

2017-03-14T19:40:31+00:00

The state of the :class:`.Session` is now present when the
:meth:`.SessionEvents.after_rollback` event is emitted, that is,  the
attribute state of objects prior to their being expired.   This is now
consistent with the  behavior of the
:meth:`.SessionEvents.after_commit` event which  also emits before the
attribute state of objects is expired.

Ensure session.no_autoflush uses finally

2017-01-04T17:12:52+00:00

The :attr:`.Session.no_autoflush` context manager now ensures that
the autoflush flag is reset within a "finally" block, so that if
an exception is raised within the block, the state still resets
appropriately.  Pull request courtesy Emin Arakelian.

Restore object to the identity_map upon delete() unconditionally

2016-10-27T13:51:50+00:00

Fixed regression caused by :ticket:`2677` whereby calling
:meth:`.Session.delete` on an object that was already flushed as
deleted in that session would fail to set up the object in the
identity map (or reject the object), causing flush errors as the
object were in a state not accommodated by the unit of work.
The pre-1.1 behavior in this case has been restored, which is that
the object is put back into the identity map so that the DELETE
statement will be attempted again, which emits a warning that the number
of expected rows was not matched (unless the row were restored outside
of the session).
