Restores erroneous deletions of `__slots__` metadata from `Undefined` types that breaks various serialization/copy mechanisms on Python >= 3.6. Also: * fix ChainedUndefined to raise AttributeError on unimplemented dunder methods to...
The `jinja2.utils.missing` singleton instance cannot be pickled since pickle cannot find `MissingType` due to the `jinja2.utils.MissingType` attribute not existing: ```python import pickle import jinja2.utils pickle.dumps(jinja2.utils.missing) ``` Running the above code...
