| * | Add new infrastructure to support greater use of __slots__ | Mike Bayer | 2022-01-21 | 1 | -0/+15 |
| | | | | | | | | | | | | | | | | | | | | * Changed AliasedInsp to use __slots__ * Migrated all of strategy_options to use __slots__ for objects. Adds new infrastructure to traversals to support shallow copy, to dict and from dict based on internal traversal attributes. Load / _LoadElement then leverage this to provide clone / generative / getstate without the need for __dict__ or explicit attribute lists. Doing this change revealed that there are lots of things that trigger off of whether or not a class has a __visit_name__ attribute. so to suit that we've gone back to having Visitable, which is a better name than Traversible at this point (I think Traversible is mis-spelled too).

| * | remove internal use of metaclasses | Mike Bayer | 2022-01-11 | 1 | -0/+762 |
| All but one metaclass used internally can now be replaced using __init_subclass__(). Within this patch we remove: * events._EventMeta * sql.visitors.TraversibleType * sql.visitors.InternalTraversibleType * testing.fixtures.FindFixture * testing.fixtures.FindFixtureDeclarative * langhelpers.EnsureKWArgType * sql.functions._GenericMeta * sql.type_api.VisitableCheckKWArg (was a mixture of TraversibleType and EnsureKWArgType) The remaining internal class is MetaOptions used by the sql.Options object which is in turn currently mostly for ORM internal use, as this type implements class level overrides for the ``+`` operator. For declarative, removing DeclarativeMeta in place of an `__init_subclass__()` class would not be fully feasible as it would break backwards compatibility with applications that refer to this class explicitly, but also DeclarativeMeta intercepts class-level attribute set and delete operations which is a widely used pattern. An option for declarative base to use `__init_subclass__()` should be provided but this is out of scope for this particular change.
