* Memoize load_path in all cases, run quick populators for path changeMike Bayer2016-10-171-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | Adds a new variant to the "isnew" state within entity loading for isnew=False, but the load path is new. This is to address the use case of an entity appearing in multiple places in the row in a more generalized way than the fixes in [ticket:3431], [ticket:3811] in that loading.py will be able to tell the populator that this row is not "isnew" but is a "new" path for the entity. For the moment, the new information is only being applied to the use of "quick" populators so that simple column loads can take place on top of a deferred loader from elsewhere in the row. As part of this change, state.load_path() will now always be populated with the "path" that was in effect when this state was originally loaded, which for multi-path loads of the same entity is still non-deterministic. Ideally there'd be some kind of "here's all the paths that loaded this state and how" type of data structure though it's not clear if that could be done while maintaining performance.

* Check for __clause_element__() in ORM insert/updateMike Bayer2016-10-051-1/+1
| | | | | | | | | | | | | | | | ORM attributes can now be assigned any object that is has a ``__clause_element__()`` attribute, which will result in inline SQL the way any :class:`.ClauseElement` class does. This covers other mapped attributes not otherwise transformed by further expression constructs. As part of this, it was considered that we could add __clause_element__() to ClauseElement, however this causes endless loops in a "while" pattern and this pattern has been identified in third party libraries. Add a test to ensure we never make that change. Change-Id: I9e15b3f1c4883fd3909acbf7dc81d034c6e3ce1d Fixes: #3802

* Ensure @compiles calls down to the original compilation schemeMike Bayer2016-06-291-2/+15
| | | | | | | | | | | | | | | Made a slight behavioral change in the ``sqlalchemy.ext.compiler`` extension, whereby the existing compilation schemes for an established construct would be removed if that construct was itself didn't already have its own dedicated ``__visit_name__``. This was a rare occurrence in 1.0, however in 1.1 :class:`.postgresql.ARRAY` subclasses :class:`.sqltypes.ARRAY` and has this behavior. As a result, setting up a compilation handler for another dialect such as SQLite would render the main :class:`.postgresql.ARRAY` object no longer compilable.

* Propagate hybrid properties / infoMike Bayer2016-04-181-1/+12
| | | | | | | | | | | Keystone and others depend on the .property attribute being "mirrored" when a @hybrid_property is linked directly to a mapped attribute. Restore this linkage and also create a defined behavior for the .info dictionary; it is that of the hybrid itself. Add this behavioral change to the migration notes.

* Honor hybrid property / method docstringsMike Bayer2016-04-181-5/+25
| | | | | | | | | | | | The docstring specified on a hybrid property or method is now honored at the class level, allowing it to work with tools like Sphinx autodoc. The mechanics here necessarily involve some wrapping of expressions to occur for hybrid properties, which may cause them to appear differently using introspection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From [PEP 479](https://www.python.org/dev/peps/pep-0479/) the correct way to terminate a generator is to return (which implicitly raises StopIteration) rather than raise StopIteration. Without this change using sqlalchemy in python 3.5 or greater results in these warnings PendingDeprecationWarning: generator '__iter__' raised StopIteration which this commit should remove.
