Bumps sqlalchemy from 1.4.34 to 1.4.36.

Release notes

Sourced from sqlalchemy's releases.

1.4.36

Released: April 26, 2022

orm

• [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

• [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

• [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.

  References: #7875

• [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
