Failure to parse some repos

[fanboimsft]

I have installed all the listed dependencies but still get an error while parsing some repos:

Apr 04 06:46:59 parsing arch
Apr 04 06:46:59 ERROR: failed: unsupported callable
Apr 04 06:47:27 parsing ataraxia
Apr 04 06:47:27 ERROR: failed: unsupported callable

It doesn't happen with every repo, for example AUR works fine:

Apr 04 06:47:13 parsing aur
Apr 04 06:47:26 done
Apr 04 06:47:30 parsing calculate
Apr 04 06:47:30 done

I don't see any other errors in the logs

Try with --fatal to get a backtrace. Which python version do you have?

I have Python 3.11.2

--fatal log:

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

Please provide more information about your system.

Also, does this work for you?

import inspect
inspect.getfullargspec(object.__init__)

It's a custom fork of KISS Linux, recompiling python without the "--without-doc-strings" flag fixed the issue.

Thanks for helping me figure this out!

[AMDmi3]

I doubt --without-doc-strings was the cause, as in the python source it looks like it just effectively replaces builtin docstrings with empty strings, so it shouldn't introduce any semantic changes. But it could be some other custom flag.
Regardless, I've removed the problematic code which is no longer needed.
