Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
On Windows (PowerShell/Windows Terminal), the queue-based modal used for
destructive slash command confirmations deadlocks because prompt_toolkit's
input channel becomes unresponsive when entered from the process_loop daemon
thread. Keystrokes never reach the key bindings, so response_queue.get()
blocks until the 120-second timeout expires.
Fix: fall back to _prompt_text_input (stdin-based) when:
1. sys.platform == 'win32' — Windows console doesn't support the modal reliably
2. Called from non-main thread — key bindings can't fire from daemon threads
3. self._app is not set — existing behavior for tests/non-interactive
This mirrors the thread-aware guard from _prompt_text_input (PR #23454).
9 new regression tests covering Windows detection, non-main thread fallback,
macOS/Linux modal preservation, and integration with _confirm_destructive_slash.
Fixes#30768
Surgical reapply of PR #30773. Original branch was many months stale (911
files / 146k LOC of unrelated reverts); the substantive ~30 LOC change in
cli.py plus the new test file were reapplied onto current main with the
contributor's authorship preserved via --author.
