- Increased codex websocket first event timeout default to 300 seconds.
- Increased default stream idle and first event timeout thresholds to 300 seconds.
- Updated stream timeout test expectations to match new 300s global default.
- Kept zero timeout resolutions distinct from missing first-event policy so the iterator does not fall back to the idle watchdog.
- Added deterministic coverage for an SSE response that opens before local prompt prefill emits its first event.
- Added a per-model first-event watchdog policy and disabled it for local OpenAI-compatible backends while retaining inter-event stall detection.
- Applied the policy to Responses and chat-completions transports with regression coverage for resolver and runtime precedence.
Fixes#6524
- Implement `drainMicrotasksUntil` helper to manage async race conditions during tests.
- Add fake timer validation to ensure the first-item watchdog is cleared when the upstream source rejects.
- Restore real timers in `afterEach` to prevent test contamination.
- Added a terminal-aware async iterator that enforces a post-completion grace window, then ends iteration and optionally aborts the request.
- Wrapped OpenAI completions streaming with terminal detection of finish-reason and usage payloads so iteration stops once a response is logically complete.
- Stopped OpenAI Responses stream consumption at terminal response events instead of waiting for connection close timeouts.
- Scoped Anthropic provider session state by base URL and model so strict-tools/fast-mode fallback state no longer leaks across unrelated endpoints or models, and fast-mode re-arming clears all matching scoped entries.
- Dropped stale strict fallback error messages after successful retries and only enabled adaptive thinking display for models that advertise support, avoiding unsupported-model 400 errors.
- Updated idle stream iteration to close the upstream iterator on non-continuing exits (including consumer early break) and added coverage for upstream closure behavior.
Always route OpenAI-family providers through getOpenAIStreamFirstEventTimeoutMs so PI_OPENAI_STREAM_FIRST_EVENT_TIMEOUT_MS wins even when callers pass per-call streamIdleTimeoutMs. The OpenAI helper now floors the first-event budget at the caller-resolved idle (which already encompasses per-call streamIdleTimeoutMs or PI_OPENAI_STREAM_IDLE_TIMEOUT_MS upstream), and explicit env disables ("0") on either knob continue to drop the watchdog.
Fixes#1603
OpenAI-compatible local servers can spend longer than the generic first-event budget processing large prompts before they emit response headers or SSE frames. The OpenAI-specific idle timeout now also acts as the OpenAI-family first-event floor unless an explicit OpenAI first-event timeout is configured.
Added regression coverage for OpenAI Responses request setup so a lower generic first-event watchdog no longer undercuts PI_OPENAI_STREAM_IDLE_TIMEOUT_MS.
Fixes#1603
- Replaced external watchdog timers with per-request SDK timeouts for first-event budget across OpenAI, Anthropic, and Azure providers.
- Keyed Python shared kernels by (sessionId, cwd) to prevent cross-directory state bleed.
- Deduplicated concurrent cold-start session acquisition for JS and Python executors.
- Moved `isOpenAIResponsesProgressEvent` to shared module and scoped display output routing per run for interleaved async cells.
- Refactored console-table tests to build explicit RuntimeHooks and pass them to JsRuntime.run.
- Refactored image coercion tests to pass explicit RuntimeHooks into JsRuntime.displayValue instead of constructor hooks.
- Added comprehensive test coverage for stream timeout behavior including first-event timeouts, idle timeouts, and watchdog cleanup.
- Added tests for streamSimple per-call timeout options forwarding to OpenAI-family providers.
- Added tests verifying that no-progress status events do not reset first-progress deadline.
- Added tests confirming external watchdog timers are cleared when iteration exits before progress.
- Restored per-provider stream watchdog with idle and first-event timeout support, progress-event filtering, and per-provider timeout overrides via `getStreamIdleTimeoutMs()` and `getStreamFirstEventTimeoutMs()`.
- Fixed silent multi-hour hangs on Codex WebSocket and z.ai/GLM-via-OpenRouter subagent runs by filtering keepalive frames from idle watchdog resets.
- Added `isOpenAICompletionsProgressChunk` export and progress-event filtering to multiple providers (Anthropic, OpenAI Responses/Completions, Azure OpenAI, Codex) to prevent keepalive frames from resetting idle timeouts.
- Un-deprecated `StreamOptions.streamIdleTimeoutMs` and wired it into all built-in providers and lazy stream forwarder with environment variable fallback support.
Removed OMP-owned first-event and idle watchdogs from provider stream consumption while preserving caller abort handling. Updated provider stream tests to assert slow/silent streams wait for provider output or caller abort instead of surfacing watchdog errors.
Fixes#1392
- Added optional per-provider fallback parameters to stream timeout helper functions so callers can widen default watchdog values safely.
- Threaded provider-specific lazy stream limits into stream creation and set Google Gemini CLI to a 300000ms first-event fallback by default.
- Added tests covering fallback defaults, env precedence, and global-default behavior for both idle and first-event timeouts.
