.. changelog::
:version: 1.4.22
:released: July 21, 2021
.. change::
:tags: bug, sql
🎟️ 6786
Fixed issue where use of the :paramref:`_sql.case.whens` parameter passing
a dictionary positionally and not as a keyword argument would emit a 2.0
deprecation warning, referring to the deprecation of passing a list
positionally. The dictionary format of "whens", passed positionally, is
still supported and was accidentally marked as deprecated.
.. change::
:tags: bug, orm
🎟️ 6775
Fixed issue in new :meth:`_schema.Table.table_valued` method where the
resulting :class:`_sql.TableValuedColumn` construct would not respond
correctly to alias adaptation as is used throughout the ORM, such as for
eager loading, polymorphic loading, etc.
.. change::
:tags: bug, orm
🎟️ 6769
Fixed issue where usage of the :meth:`_result.Result.unique` method with an
ORM result that included column expressions with unhashable types, such as
``JSON`` or ``ARRAY`` using non-tuples would silently fall back to using
the ``id()`` function, rather than raising an error. This now raises an
error when the :meth:`_result.Result.unique` method is used in a 2.0 style
ORM query. Additionally, hashability is assumed to be True for result
values of unknown type, such as often happens when using SQL functions of
unknown return type; if values are truly not hashable then the ``hash()``
itself will raise.
For legacy ORM queries, since the legacy :class:`_orm.Query` object
uniquifies in all cases, the old rules remain in place, which is to use
``id()`` for result values of unknown type as this legacy uniquing is
mostly for the purpose of uniquing ORM entities and not column values.
.. change::
:tags: orm, bug
🎟️ 6771
Fixed an issue where clearing of mappers during things like test suite
teardowns could cause a "dictionary changed size" warning during garbage
collection, due to iteration of a weak-referencing dictionary. A ``list()``
has been applied to prevent concurrent GC from affecting this operation.
.. change::
:tags: bug, sql
🎟️ 6770
Fixed issue where type-specific bound parameter handlers would not be
called upon in the case of using the :meth:`_sql.Insert.values` method with
the Python ``None`` value; in particular, this would be noticed when using
the :class:`_types.JSON` datatype as well as related PostgreSQL specific
types such as :class:`_postgresql.JSONB` which would fail to encode the
Python ``None`` value into JSON null, however the issue was generalized to
any bound parameter handler in conjunction with this specific method of
:class:`_sql.Insert`.
.. change::
:tags: bug, engine
🎟️ 6740
Added some guards against ``KeyError`` in the event system to accommodate
the case that the interpreter is shutting down at the same time
:meth:`_engine.Engine.dispose` is being called, which would cause stack
trace warnings.
.. change::
:tags: bug, orm, regression
🎟️ 6793
Fixed critical caching issue where the ORM's persistence feature using
INSERT..RETURNING would cache an incorrect query when mixing the "bulk
save" and standard "flush" forms of INSERT.
