:meth:`.MutableBase.coerce` method to be used, even though
the code seemed to indicate this intent, so this now works
and a brief example is added. As a side-effect,
the mechanics of this event handler have been changed so that
new :class:`.MutableComposite` types no longer add per-type
global event handlers. Also in 0.7.10

become an externally usable package but still remains within the main sqlalchemy parent package.
in this system, we use kind of an ugly hack to get the noseplugin imported outside of the
"sqlalchemy" package, while still making it available within sqlalchemy for usage by
third party libraries.
have enough of its state set up to work
correctly within the unpickle() event established
by the mutable object extension, if the object
needed ORM attribute access within
__eq__() or similar. [ticket:2362]
expired after an insert or update operation, instead
of regenerated in place. This ensures that a
column value which is expired within a flush
will be loaded first, before the composite
is regenerated using that value. [ticket:2309]
- [bug] The fix in [ticket:2309] also emits the
"refresh" event when the composite value is
loaded on access, even if all column
values were already present, as is appropriate.
This fixes the "mutable" extension which relies
upon the "load" event to ensure the _parents
dictionary is up to date, fixes [ticket:2308].
Thanks to Scott Torborg for the test case here.
if None or a non-corresponding type were set,
an error would be raised. None is now accepted
which assigns None to all attributes,
illegal values raise ValueError.
access to the cls/self.tables/classes registries
- express orm/_base.py ORMTest in terms of engine/_base.py TablesTest,
factor out common steps into TablesTest, remove AltEngineTest as a
separate class. will further consolidate these base classes
- add pickle/unpickle events to ORM events. these are needed
for the mutable extension.
- finish mutable extension documentation, consolidate examples,
add full descriptions
- streamline interfaces, get Mutable/MutableComposite to be as minimal
in usage as possible
- docs for mutable, warnings regrarding mapper events being global
- move MutableType/mutable=True outwards, move orm tests to its
own module, note in all documentation
- still need more events/tests for correct pickling support of
composites, mutables. in the case of composites its needed
even without mutation. see [ticket:2009]
