Issue with case sensitivity on MacOS X

[astrofrog]

Astropy has M_bol and m_bol objects in the same sub-package, and this causes issues when using sphinx-automodapi because MacOS X is case-insensitive meaning that the .rst pages for each of these objects will conflict:

Hit this too. Perhaps there could be an option which causes file names to be rewritten (say, appending an underscore after each capital letter)?

Apple should just make their stuff be case sensitive. I don't see how we can fix this.

[bsipocz]

@pllim - I think we could maybe add a warning on osx, if there was any such sphinx warnings that say that some of the above might have been caused due to case sensitivity. As I recall it was a bit of a puzzle when we first run into the problem, such a warning would save a bit of time for anyone freshly running into it.

This has bitten me again, now with pyvo where we have classes like pyvo.auth.authsession.AuthSession. This generates warnings like these (via autodoc):

WARNING: autodoc: failed to import method 'AuthSession.add_security_method_for_url' from module 'pyvo.auth'; the following exception was raised:
Traceback (most recent call last):
  File "/Users/bsipocz/.pyenv/versions/3.11.0/lib/python3.11/site-packages/sphinx/util/inspect.py", line 440, in safe_getattr
    return getattr(obj, name, *defargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The above exception was the direct cause of the following exception:

and an rst file like this:

AuthSession
===========

.. currentmodule:: pyvo.auth

.. autoclass:: AuthSession
   :show-inheritance:

   .. rubric:: Methods Summary

   .. autosummary::

      ~AuthSession.add_security_method_for_url
      ~AuthSession.delete
      ~AuthSession.get

   .. automethod:: delete
   .. automethod:: get
   .. automethod:: post
   .. automethod:: put
   .. automethod:: update_from_capabilities

[bsipocz]

Note, this case is someone different from the m_bol vs M_bol, as there is only one AuthSession class, and it's exposed in the auth.AuthSession namespace, there is no need for having anything for the authsession.py module...

[bsipocz]

OK, same stuff different phrasing: sphinx-doc/sphinx#1495

[bsipocz]

And here is a patch that maybe useful for us, too?: scikit-learn/scikit-learn#13022

Hello!

I think I got the same issue as @bsipocz where I am using macos with sphinx-automodapi v0.14.1 and sphinx 5.3.0.

In my package I have a module pyswgo.io.eventsource which contains the class EventSource with a (static) method called is_compatible and when I compile the docs I get for example

WARNING: autodoc: failed to import method 'EventSource.is_compatible' from module 'pyswgo.io'; the following exception was raised:
Traceback (most recent call last):
  File "/Users/michele/Applications/mambaforge/envs/pyswgo/lib/python3.9/site-packages/sphinx/util/inspect.py", line 376, in safe_getattr
    return getattr(obj, name, *defargs)
AttributeError: module 'pyswgo.io.EventSource' has no attribute 'is_compatible'

/Users/michele/Applications/SWGO/irf-production/docs/api/pyswgo.io.EventSource.rst:30:<autosummary>:1: WARNING: py:obj reference target not found: pyswgo.io.EventSource.EventSource.is_compatible

Is this the same issue?

I know of the existence of the autosummary_filename_map and I naïvely tested it as

autosummary_filename_map = {"pyswgo.io.eventsource.Eventsource": "EventSource"}

right after the extensions dictionary in conf.py, but to no use.

Is there any news about this issue?

If for some reason my problem is of a different nature I will gladly bother your with a new issue :)

[bsipocz]

I tried a bit of autosummary_filename_map but it didn't work out of the box for the pyvo case above, and I haven't dug deep enough yet to see what needed to be fixed for automodapi to allow it to work.
To be practical, ultimately I may just go ahead and rename or merge the files that have the same names as the single class they contain.
