The chatgpt.com/backend-api/codex endpoint has an intermittent failure mode where it accepts the connection but never emits a single stream event — the socket just hangs. Direct sequential probing reproduces it (0 events, no HTTP status), and a fresh reconnect then succeeds in ~2s. Today the only guard is the wall-clock stale timeout in interruptible_api_call, so a dead-on-arrival connection is held for the full stale window (90-900s depending on context / config) before the retry loop can reconnect — minutes of wasted wall time per stall, at a rate of ~20% of calls during affected windows. Add a TTFB watchdog scoped to the codex_responses path: - codex_runtime.run_codex_stream stamps agent._codex_stream_last_event_ts on *every* stream event (not just output-text deltas), so reasoning-only and tool-call-only turns are not mistaken for a stall. - interruptible_api_call resets that marker before the worker starts and, while it is still None, kills the connection once elapsed exceeds the TTFB cutoff (default 45s, tunable via HERMES_CODEX_TTFB_TIMEOUT_SECONDS, 0 disables). The raised TimeoutError flows through the existing retry path unchanged. Once any event has arrived the stream is healthy and only the existing wall-clock stale timeout applies, so legitimate long generations are never interrupted. Gated to codex_responses; the chat_completions non-stream, anthropic and bedrock branches have no first-event signal and are untouched. Adds tests/agent/test_codex_ttfb_watchdog.py covering the stall kill, the events-flowing pass-through, and the env-disable path. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
