The documentation for socket.AddressFamily (unlike to SocketType) isn't generated in html page by pydoc.

May be issue20654 is similar to this issue.

I couldn't reproduce this issue. I'm attaching HTML output of both socket.AddressFamily and socket.SocketType enum types.

Try "./python -m pydoc -w socket".

I found the culprit. The AddressFamily is not registered in _socket module. I created a preliminary patch to show the culprit.

"I found the culprit. The AddressFamily is not registered in _socket module. I created a preliminary patch to show the culprit."

That's not surprising, this type is created in socket (socket.py), not in _socket (the C module). Your patch is wrong.

Ah, now I see what is wrong.

Actually AddressFamily is missing in text output of pydoc too. Because "AddressFamily" is not included in the __all__ list. SocketType is included, but this is different SocketType, SocketType from _socket (see issue20386).

Here is a patch which fixes this issue.

I suggested to not document new enums of the socket module (ex: AddressFamily, SocketType) when they were added. I don't think that they should be part of Python public API.

We should discuss this suggestion on Python-Dev. It affects the use of enums in other modules.

As I said in msg209237:
------------------------------------------------------------------------------------
> The containers are there to help with discoverability.  If you want to know what
> all the (common) AF values are you can either do
> 
>     [name for name in dir(socket) if name.isupper() and name.startswith('AF_')]
> 
> or
> 
>     list(socket.AddressFamily)
------------------------------------------------------------------------------------

The Enum classes have been documented, so they should be in __all__.
