Fix parsing of PEP 695 functions

[picnixz]

Supersedes #11796.

[picnixz]

Hum, there's a consistent CI failure here but I doubt it's related to my change.

[picnixz]

Some possibility: it's because we're running tests in parallel but I don't know why it would consistently fail =/

[AA-Turner]

We don't run tests in parallel on Windows or macOS, yet.

We don't run tests in parallel on Windows or macOS, yet.

This is extremely weird! I don't really know why it's like this then :( I'm trying some stuff here and there (I don't have a testing environment on Windows...)

[picnixz]

Ok, so even without the exec(), we still have the Windows failure:

tests/test_extensions/test_ext_intersphinx_cache.py::test_intersphinx_project_fixture PASSED [ 71%]
tests/test_extensions/test_ext_intersphinx_cache.py::test_load_mappings_cache FAILED [ 71%]

And it appears that the following doesn't create the environment correctly?

        with http_server(InventoryHandler, port=project.port):
            # clean build
            confoverrides = BASE_CONFIG | {'intersphinx_mapping': project.record}
            app = SphinxTestApp('dummy', srcdir=tmp_path, confoverrides=confoverrides)
            app.build()
            app.cleanup()

What's funny is that it's something I wrote. I will be offline until Saturday, so if you can investigate this I would be happy :(

[picnixz]

I'm not sure if the following error:

ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

actually happened before or after the failed assertion. Because the http_server context manager did not seem to fail (otherwise why would we have entry = project.make_entry()) but maybe http_server suppressed an exception?

[picnixz]

So now the CI works..?

The best kind of errors are transient...
