Upgrade to release 1.4.2: orm: - Added support for the declared_attr object to work in the context of dataclass fields. - Fixed issue in new ORM dataclasses functionality where dataclass fields on an abstract base or mixin that contained column or other mapping constructs would not be mapped if they also included a “default” key within the dataclasses.field() object. - Fixed regression where the Query.selectable accessor, which is a synonym for Query.__clause_element__(), got removed, it's now restored. - Fixed regression where use of an unnamed SQL expression such as a SQL function would raise a column targeting error if the query itself were using joinedload for an entity and was also being wrapped in a subquery by the joinedload eager loading process. - Fixed regression where the Query.filter_by() method would fail to locate the correct source entity if the Query.join() method had been used targeting an entity without any kind of ON clause. - Fixed regression where the SQL compilation of a Function would not work correctly if the object had been "annotated", which is an internal memoization process used mostly by the ORM. In particular it could affect ORM lazy loads which make greater use of this feature in 1.4. - Fixed regression where the ConcreteBase would fail to map at all when a mapped column name overlapped with the discriminator column name, producing an assertion error. The use case here did not function correctly in 1.3 as the polymorphic union would produce a query that ignored the discriminator column entirely, while emitting duplicate column warnings. As 1.4's architecture cannot easily reproduce this essentially broken behavior of 1.3 at the select() level right now, the use case now raises an informative error message instructing the user to use the .ConcreteBase._concrete_discriminator_name attribute to resolve the conflict. To assist with this configuration, .ConcreteBase._concrete_discriminator_name may be placed on the base class only where it will be automatically used by subclasses; previously this was not the case. engine: - Restored top level import for sqlalchemy.engine.reflection. This ensures that the base Inspector class is properly registered so that inspect() works for third party dialects that don't otherwise import this package. sql: - Fixed issue where using a func that includes dotted packagenames would fail to be cacheable by the SQL caching system due to a Python list of names that needed to be a tuple. - Fixed regression in the case() construct, where the "dictionary" form of argument specification failed to work correctly if it were passed positionally, rather than as a "whens" keyword argument. mypy: - Fixed issue in MyPy extension which crashed on detecting the type of a Column if the type were given with a module prefix like sa.Integer(). postgresql: - Rename the column name used by a reflection query that used a reserved word in some postgresql compatible databases.

meta-python
Introduction
This layer is intended to be the home of python modules for OpenEmbedded.
Dependencies
The meta-python layer depends on:
URI: git://git.openembedded.org/openembedded-core
layers: meta
branch: master
revision: HEAD
URI: git://git.openembedded.org/meta-openembedded
layers: meta-oe
branch: master
revision: HEAD
Please follow the recommended setup procedures of your OE distribution. For Angstrom that is: http://www.angstrom-distribution.org/building-angstrom, other distros should have similar online resources.
