name: run-cpython-tests description: Run the CPython regression test suite in this repo via scripts/run_cpython_tests.sh with parallel execution, enforce a per-test timeout, capture output to cpython_full_test_run.log, and summarize failures from that log.

Run CPython tests

Run the full suite

• Run with full permissions, including network.
• Use a 3-minute per-test timeout and keep parallelism enabled (run_cpython_tests.sh already uses -j0).
• If the local cpython/ checkout is missing the target branch, re-run with FETCH_CPYTHON=1 to allow a network update.
• Capture output to a single log file while preserving the exit status:

Copyset -o pipefail
./scripts/run_cpython_tests.sh --timeout 180 2>&1 | tee cpython_full_test_run.log

Summarize failures from the log

• Locate failure anchors:

Copyrg -n "^(FAIL|ERROR|TIMEOUT|CRASHED|INTERRUPTED|LEAKED|ENV_CHANGED):" cpython_full_test_run.log

• Extract each failure block (look for the separator lines of ===) and classify the failure based on the first error line after the traceback.
• Use these categories in the summary:
  • FAIL: assertion mismatch or explicit test failure; call out the mismatched expectation.
  • ERROR: unexpected exception; report the exception type and message.
  • TIMEOUT: test exceeded 180 seconds; call out the hang/timeout.
  • CRASHED/FATAL: interpreter crash; mention the fatal error or signal.
  • LEAKED/ENV_CHANGED: resource leak or environment mutation; mention the resource.
• Summarize each failing test as: test_name: <category> - <short reason from output>.
