- 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.
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.
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
just the identity map lookup + expired check, the other
which does the load unconditionally. All the refresh/deferred load
calls use the unconditional load method, query.get() and
LoadLazyAttribute call the identity check by itself first. m2o
lazyloads for object already in the identity map callcounts are
now cut in half, since no Query object is created.
outside of "sqlalchemy" and under "test/".
Rationale:
- coverage plugin works without issue, without need for an awkward
additional package install
- command line for "nosetests" isn't polluted with SQLAlchemy options
[ticket:1949]
- more docs for engine, pool, DDL events
- update DDL sequences documentation to use events
- update DDL() docstring to refer to execute_if()
- document parameters for DDLElement.execute_if()
- add retval=True flag to Engine.on_before_execute(), on_before_cursor_execute().
wrap the function if retval=False, check for appropriate usage of the flag, add
tests.
- remove ScopedSession.mapper and tests entirely
- remove ExtensionCarrier and tests
- change remaining tests that use MapperExtension to use MapperEvents
