What issue are you seeing?

Codex sandbox appears to hang after multi-file Black runs complete.

Environment:

  • Repo: /home/tomek/haymaker
  • Python: .venv/bin/python 3.12.13
  • Black: 26.5.1
  • Command: timeout 20 .venv/bin/python -m black --check --fast --target-version py312 --workers 1 haymaker/supervisor.py tests/test_supervisor.py

Observed:

  • Black prints: "All done! ... 2 files would be left unchanged."
  • The process then does not exit.
  • timeout kills it after 20s with exit code 124.
  • Same behavior with: --workers 1 BLACK_NUM_WORKERS=1 BLACK_CACHE_DIR=/tmp/haymaker-black-cache --no-cache .venv/bin/black instead of python -m black

Control:

  • Running Black on one file exits normally: .venv/bin/python -m black --check --fast --target-version py312 haymaker/supervisor.py
  • Running Black one file at a time exits normally.
  • The hang seems specific to multi-file Black invocation inside the Codex sandbox.

Expected:

  • Codex sandbox should allow the completed Black process to exit normally.
  • Multi-file formatter commands should not hang after successful completion.

Impact:

  • Agents repeatedly waste time diagnosing or working around a standard formatting command.
  • It also makes validation unreliable because a successful Black result is converted into timeout failure.

The actionable ask is: “Please investigate process-pool / child-process shutdown behavior in the Codex sandbox for completed multi-file Black runs.”

What steps can reproduce the bug?

Uploaded thread: 019e82aa-faaf-78e2-abdc-c25455637c21

What is the expected behavior?

codex being able to run a simple 'black' command on all project files.
