stubgen timeout on building docs on MacOS

stubgen timeout on building docs on MacOS

python -m mypy.stubgen -m mypackage -o ./stubs --include-docstrings

The stubgen tool always reports a timeout waiting for queued package properties. The timeout happens in the following code block:

-> moduleinspect.py

(155) def _get_from_queue(self) -> ModuleProperties | str | None:

It seems the subprocess never queues package properties.

To Reproduce

This error occurs on MacOS only.

python -m mypy.stubgen -m mypackage -o ./stubs --include-docstrings

Expected Behavior

It should work as smooth as on Windows and Linux, outputting the stub file without further issues.

Actual Behavior

Your Environment

• Mypy version used: 1.7.0+dev
• Mypy command-line flags: --include-docstrings -p myextmodule
• Mypy configuration options from mypy.ini (and other config files):
• Python version used: cp3.11
• Platform: MacOS

Inizia da mypy/moduleinspect.py, in particolare da ModuleInspect._get_from_queue(), e riproduci il problema con il comando stubgen fornito su macOS. Confronta il comportamento di subprocess e queue con Windows o Linux, quindi verifica che il comando termini e scriva gli stub previsti senza timeout.
