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

Bắt đầu với mypy/moduleinspect.py, đặc biệt là ModuleInspect._get_from_queue(), và tái hiện lỗi bằng lệnh stubgen được cung cấp trên macOS. So sánh hành vi của subprocess và queue với Windows hoặc Linux, sau đó xác minh rằng lệnh hoàn tất và ghi các stub mong đợi mà không bị timeout.
