Repository: deshaw/pyflyby
Base commit: c25497f (image tag)
Issue: tidy-imports --black fails with no pyproject.toml (PyInf#11819) When using --black outside of a tree with a pyproject.toml, tidy-imports 1.8.9 crashes with the attached traceback. tidy-imports 1.8.6 doesn't exhibit this issue. Started happening after commit - https://github.com/deshaw/pyflyby/commit/8c10f4971d328fc985b0910f1397b4c36a67c318 ``` > tidy-imports --black /var/tmp/a.py --no-remove-unused Traceback (most recent call last): File "/usr/local/python/python-3.11/std/lib64/python3.11/site-packages/pyflyby/_cmdline.py", line 391, in process_actions action(m)

Files to edit

lib/python/pyflyby/_importstmt.py

Approach: Read the read_black_config function to understand how it handles the result from find_pyproject_toml, then determine the minimal fix.

Finish summary: Fixed the `tidy-imports --black` crash when no `pyproject.toml` exists. The `read_black_config()` function in `_importstmt.py` was passing `None` (returned by `find_pyproject_toml` when no config file exists) directly to `parse_pyproject_toml()`, causing a `TypeError: expected str, bytes or os.PathLike object, not NoneType`. Added a `None` check to return an empty config dict `{}` in that case. Both specification tests and all 32 tests in `test_importstmt.py` now pass.
