Elegant typehints' qualname overrides aren't processed in autodoc's show-inheritance option

[laymonage]

When using the :show-inheritance: option for automodule, autoclass, or autoexception directives, the qualname overrides specified for elegant_typehints are not processed by Sphinx. The :show-inheritance: option will make Sphinx also list the base classes (and link them) for each class. However, since the qualname_overrides aren't processed, using the :show-inheritance: option will throw errors for classes whose base classes' qualnames should be overridden.

For example, with the following rst file:

Exceptions
==========

.. automodule:: mypackage.exceptions
   :members:
   :show-inheritance:

and the following mypackage/exceptions.py:

import requests


class MyConnectionError(requests.ConnectionError):
    pass

This will throw an error because requests.ConnectionError's qualname is requests.exceptions.ConnectionError but the object inventory exposes requests.ConnectionError... which is the reason why we'd use qualname_overrides from elegant typehints. The expected behavior is that elegant typehints should handle this case as well.

P.s. on another note, this may actually be expected as it's not related to type hints. Still, I wonder if we can elevate the qualname overrides feature into something more general, maybe as its own extension.

Hey, thank you for the nice report. As mentioned in the docs:

Once either sphinx issue 4826 or sphinx-autodoc-typehints issue 38 are fixed, this part of the functionality will no longer be necessary

I created #19 to add this functionality, but it doesn’t work yet. IDK what I’m doing wrong.

Breakpoints don’t even hit that function …
