Track guessed as N from the FAILING STEP — line 2 of 15, /tmp/test_nilpy_callsubst26 | diff -u test/test_nilpy_subscript_store_on_a_call_result.expected -, which names test/test_nilpy_subscript_store_on_a_call_result.expected. Not from the job's name or its src: those describe what the job is ABOUT, and this job's recipe spans 2 source file(s). The ranker reads frontmatter, so this line — not the body — decides who works it; correct it if the guess is wrong.

origin/master has advanced 1 commit(s) since this sha. Re-verify at current HEAD before acting — the callback is tagged to the sha that was tested, which may no longer be the state of the tree.

Repro

tools/testmgr.py --tier native --job 'test-core#src:test/test_nilpy_subscript_store_on_a_call_result.npy' at 67f0878f2e594f042e00005391b213922d8f1047

Range

The named sha 67f0878f2e59 CANNOT be the cause — it touches no buildable file (docs / tickets / tstate only). It is the sha that was TESTED, i.e. the upper bound of an untested range; the cause is somewhere below it.

bad 67f0878f2e59, last good e572bd42501e, 1 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.
