| | | | | | | that the "id" passed from the pickler is turned into a string to prevent against bytes being parsed on Py3K, as well as that ``relationship()`` and ``orm.join()`` constructs are now properly serialized. [ticket:2698] and some other observed issues.

* - refactor of pathing mechanics, to address #2614, #2617Mike Bayer2012-12-011-0/+8
| | | | | | | | | | | | | | | | | | | - paths now store Mapper + MapperProperty now instead of string key, so that the parent mapper for the property is known, supports same-named properties on multiple subclasses - the Mapper within the path is now always relevant to the property to the right of it. PathRegistry does the translation now, instead of having all the outside users of PathRegistry worry about it, to produce a path that is much more consistent. Paths are now consistent with mappings in all cases. Special logic to get at "with_polymorphic" structures and such added also. - AliasedClass now has two modes, "use_mapper_path" and regular; "use_mapper_path" is for all those situations where we put an AliasedClass in for a plain class internally, and want it to "path" with the plain mapper. - The AliasedInsp is now the first class "entity" for an AliasedClass, and is passed around internally and used as attr._parententity and such. it is the AliasedClass analogue for Mapper.

multiple aliases of the same class (will add tests in [ticket:1218]) - Added a new extension sqlalchemy.ext.serializer. Provides Serializer/Deserializer "classes" which mirror Pickle/Unpickle, as well as dumps() and loads(). This serializer implements an "external object" pickler which keeps key context-sensitive objects, including engines, sessions, metadata, Tables/Columns, and mappers, outside of the pickle stream, and can later restore the pickle using any engine/metadata/session provider. This is used not for pickling regular object instances, which are pickleable without any special logic, but for pickling expression objects and full Query objects, such that all mapper/engine/session dependencies can be restored at unpickle time.
