[orm] [bug] [regression] Fixed regression where the change made for #7861, released in
version 1.4.33, that brought the Insert construct to be partially
recognized as an ORM-enabled statement did not properly transfer the
correct mapper / mapped table state to the Session, causing the
Session.get_bind() method to fail for a Session that was
bound to engines and/or connections using the Session.binds
parameter.
[orm] [declarative] [bug] Modified the DeclarativeMeta metaclass to pass cls.__dict__
into the declarative scanning process to look for attributes, rather than
the separate dictionary passed to the type's __init__() method. This
allows user-defined base classes that add attributes within an
__init_subclass__() to work as expected, as __init_subclass__() can
only affect the cls.__dict__ itself and not the other dictionary. This
is technically a regression from 1.3 where __dict__ was being used.
[engine] [bug] Fixed a memory leak in the C extensions which could occur when calling upon
named members of Row when the member does not exist under Python
3; in particular this could occur during NumPy transformations when it
attempts to call members such as .__array__, but the issue was
surrounding any AttributeError thrown by the Row object. This
issue does not apply to version 2.0 which has already transitioned to
Cython. Thanks much to Sebastian Berg for identifying the problem.
[engine] [bug] Added a warning regarding a bug which exists in the Result.columns()
method when passing 0 for the index in conjunction with a Result
that will return a single ORM entity, which indicates that the current
behavior of Result.columns() is broken in this case as the
Result object will yield scalar values and not Row
objects. The issue will be fixed in 2.0, which would be a
backwards-incompatible change for code that relies on the current broken
