Phase 13.1. The test runner script crashed on UnicodeEncodeError at line 185
(the summary table print). Without this fix, the test suite cannot run to
completion. Fix: sys.stdout.reconfigure(encoding='utf-8', errors='replace')
at the start of main(). This is the FIRST action of Phase 13 -- without it,
no other test verification is possible.
The crash was triggered by box-drawing characters (U+2502 etc.) in the
summary table being printed to a Windows console using cp1252 encoding.
The reconfigure enables UTF-8 output on Windows and is a no-op on
Linux/macOS where stdout is already UTF-8 by default.
The os._exit(2) change in 719c5e27 introduced a regression: the watchdog's daemon thread continues running through pytest's interpreter shutdown. On EVERY batch (even ones that complete successfully in 17s), the watchdog's time.sleep(30.0) elapses during finalization and the thread calls os._exit(2) just as pytest is wrapping up. Result: every batch was reported as 'Batch N failed' by run_tests_batched.py, even ones with '126 passed in 17.14s'.
Revert watchdog to os._exit(0) — its original purpose (force-exit any stuck pytest at 30s) doesn't need a non-zero code; it's a sledgehammer, not a signal. The runner does its own failure detection.
Update scripts/run_tests_batched.py to:
- Use subprocess.run(timeout=180) per batch
- Catch TimeoutExpired as a batch failure (with elapsed time + reason printed)
- Catch CalledProcessError as a batch failure (preserved from before)
- Print elapsed time for every batch (pass or fail) so hang behavior is visible
- Print a final summary that lists all FAILED FILES (not batches) for easy re-running
- Add --batch-size and --timeout CLI flags
- Add 1-space indentation + type hints per project style
Verified: ast.parse OK; --help works; test_conftest_watchdog 3/3 pass.
