Maintainer rework of #45580 (issue #54036) on top of the contributor's cherry-pick, which targeted spectrum-ts 3.1.0 while main pins 8.0.0: Sidecar (primary detection, new): - stream-staleness.mjs: pure decision rules, executable under node. * classifyProbeRejection: only a not-found-shaped rejection of the synthetic-id read counts as a completed round-trip (ALIVE); any other rejection is INCONCLUSIVE — never alive. The original /probe treated ANY rejection as alive, which was too loose. * shouldProbe: probe only after 10+ min of stream silence (configurable via PHOTON_STREAM_SILENCE_PROBE_MS; <=0 disables) with a cooldown. * isZombieSuspect: zombie only on silence past threshold AND a probe-proven live channel. Silence alone NEVER degrades (shared lines can be quiet for hours); inconclusive probes NEVER degrade (network may be down — the iterator will throw and the re-subscribe loop recovers on its own). - index.mjs: track last inbound-iterator yield (noteInboundYield), run a 30s watchdog tick, and on a confirmed zombie feed markStreamDegraded -> the existing exit-75 restart path. /healthz gains a stream.staleness block (silentForMs, threshold, lastProbeOutcome, zombieSuspected). /probe reworked to strict semantics: 200 only on a proven round-trip, 503 with outcome hung|inconclusive otherwise. Adapter (second layer, reworked): - _probe_once returns tri-state alive|hung|inconclusive; only a hung sidecar HTTP call counts toward the respawn counter — inconclusive resets nothing and triggers nothing. - default probe_interval_seconds 60 -> 600 (conservative; avoid restart storms on quiet lines). - _monitor_sidecar_health surfaces zombieSuspected from /healthz as a warning; the fatal UPSTREAM_STREAM_DEGRADED path is unchanged and fires when the sidecar escalates. Tests: test_zombie_stream_watchdog.py executes the real node decision module and drives the adapter against mocked /healthz responses; test_presence_watchdog.py updated for the tri-state probe. Also adds contributor mappings for nickkarhan (#53283) and vaibhavjnf (#45580). |
