17 00:00:00 2001 From: Leoyzen Date: Sun, 7 Jun 2026 17:32:42 +0800 Subject: [PATCH 04/51] feat(opencode): integrate OpenCodeSessionPoolIntegration and complete session-scoped event consumer refactor - Add OpenCodeSessionPoolIntegration to ServerState and create_app() - Use integration for session creation, message routing, and cleanup - Add close_session() to OpenCodeSessionPoolIntegration for proper cleanup - Update delete_session route to use integration.close_session() - Add backward compatibility when integration is not available - Fix CancelledError handling to not re-raise (matching old behavior) - Add conversation history preservation in CancelledError/ Exception handlers - Update test fixture to mock SessionPool for new architecture - Add session-scoped consumer tests Completes

Core changes: - process_tool_event(): Remove direct EventBus publish, always return combined ToolCallCompleteEvent. Caller decides routing. - _run_agentlet_core(): Add ToolCallStartEvent mapping for FunctionToolCallEvent and PartStartEvent(BaseToolCallPart), with deduplication by tool_call_id. Capture process_tool_event() return value and enqueue into local queue. - EventBusHooksAdapter: Disable before_tool_execute/after_tool_execute event publishing (now transparent passthroughs). Tool events come exclusively from the stream path. This fixes two observable bugs: 1. Missing ToolCallStartEvent in opencode TUI (start event wasn't mapped) 2.

The manual subscription in `subagent_tools.py` duplicates this and only adds filesystem output, which is not needed for frontend streaming. + +**Alternative considered**: Keep filesystem output as a side effect. Rejected because filesystem persistence should be explicit (e.g., a dedicated tool) rather than a side effect of event routing. + +### Decision 2: Remove manual `ctx.events.emit_event()` calls from `workers.py` and `pool.py` + +**Rationale**: `ctx.events.emit_event()` emits to the local `MessageNode` connection system, not directly to EventBus. In SessionPool mode, `run_stream()` already flows through TurnRunner which publishes to EventBus. The manual `emit_event()` calls create duplicate events in the local system. + +**Important**: We do NOT remove `SubAgentEvent` entirely. The protocol layer (both ACP and OpenCode) relies on `SubAgentEvent` for proper event attribution and routing. `SubAgentEvent` wrapping is still needed — it just shouldn't be done manually in the business layer. Instead, TurnRunner will handle this automatically when publishing to EventBus. + +**Note**: If TurnRunner does not currently wrap events in `SubAgentEvent`, this change reveals a gap that needs to be addressed separately. The business layer cleanup should proceed, and the protocol layer should be updated to handle raw child session events correctly (see Open Questions). + +### Decision 3: Use `session_pool.run_stream()` for sync mode, `receive_request()` for async mode + +**Rationale**: +- **Sync mode** (workers, tools that return results): Must block until completion and extract the final result. `session_pool.run_stream(child_session_id, prompt)` blocks, yields events, and allows extracting `final_content` from `StreamCompleteEvent`. Events naturally flow to EventBus via TurnRunner. +- **Async mode** (background tasks): Fire-and-forget is the desired behavior. `session_pool.receive_request(child_session_id, prompt)` starts the run in background and returns immediately. + +**Correction from initial design**: The initial design incorrectly proposed `receive_request()` for sync mode. This was identified as a critical flaw in review — `receive_request()` is fire-and-forget and cannot return a synchronous result to the calling agent. + +### Decision 4: Explicit non-SessionPool fallback + +**Rationale**: Some deployments may use agents standalone without SessionPool. We need a clear policy. + +**Decision**: Require SessionPool for subagent tools. If `session_pool` is None, raise a clear error. Standalone agent usage should use direct `agent.run()` instead of subagent tools. This simplifies the code by eliminating the dual-path branching. + +## Risks / Trade-offs + +| Risk | Level | Mitigation | +|------|-------|------------| +| Sync mode result extraction | High | Use `session_pool.run_stream()` which blocks and yields events; extract final content from `StreamCompleteEvent` | +| SubAgentEvent removal breaks protocol layer | High | **Do not remove SubAgentEvent** — TurnRunner should wrap events. If not yet implemented, add protocol-layer task to handle raw child events (see Open Questions) | +| Duplicate event processing | Medium | Parent consumer uses `scope="descendants"` and child consumers also receive events. This is existing behavior, not new.

The ACP converter and OpenCode event processor both rely on `SubAgentEvent` for proper attribution. This should be verified before implementing this change. + +2. **Should child consumers use `scope="session"` instead of `scope="descendants"`?** If parent consumer uses `scope="descendants"`, it receives all child events. If child consumers also exist, events are processed twice. Consider changing child consumers to `scope="session"` to avoid duplicate processing. + +3. **How should standalone agents work?** If SessionPool is required, standalone usage must be documented. Alternatively, a minimal fallback could be kept that runs the agent without event routing (for testing/CLI usage). \ No newline at end of file diff --git a/openspec/changes/archive/2026-06-07-cleanup-business-layer-event-routing/proposal.md b/openspec/changes/archive/2026-06-07-cleanup-business-layer-event-routing/proposal.md new file mode 100644 index 000000000..28b27a0e4 --- /dev/null +++ b/openspec/changes/archive/2026-06-07-cleanup-business-layer-event-routing/proposal.md @@ -0,0 +1,32 @@ +## Why + +The business layer maintains **three distinct event routing paths** for subagent events, creating redundancy and inconsistency.

Removing the `is not None` branch means it will always return `combined` — same behavior for standalone mode. | +| Event ordering in local queue may be wrong if multiple tool calls interleave | Low | Local `asyncio.Queue` is FIFO. Events are produced by a single `async for event in agent_run:` loop, so no interleaving is possible within a single run. | +| Test breakages from changed `process_tool_event()` behavior | Low | Update tests that mock or assert on direct EventBus publish. The red flag tests document current broken behavior and should be converted to positive assertions. | +| `EventBusHooksAdapter` disable causes unexpected side effects | Low | Only disabling `before_tool_execute` / `after_tool_execute` event publishing. The adapter remains as a capability wrapper. `before_run` is preserved unless verified redundant. | +| Performance: adding events to queue instead of direct publish adds latency | Very Low | Local queue operations are nanosecond-scale. EventBus publish still happens in TurnRunner, just slightly later. No measurable impact on user-facing latency. | + +## Migration Plan + +This is a bugfix with no migration needed: +- No configuration changes required +- No database schema changes +- No API contract changes +- Rollback: revert the two-file change + +## Open Questions + +1. **Does `EventBusHooksAdapter.before_run` serve any purpose after this change?** — `_stream_events()` already yields `RunStartedEvent` at the top. The hooks adapter's `before_run` may produce a duplicate. Verify if it can also be disabled. +2. **Should we add an integration test that exercises the full SessionPool → EventBus → opencode TUI path?** — The red flag tests cover the core logic, but an end-to-end test would prevent regression. +3. **Does the event_bus branch need `merge_queue_into_iterator`?** — The non-event_bus branch uses `merge_queue_into_iterator(stream, run_ctx.event_queue)` to merge injected prompts. The event_bus branch does not. In SessionPool mode, `run_ctx.event_queue` may contain injected prompts that need merging.

Other auxiliary paths (permission handling, list sessions) do not invoke the agent but still read from `ServerState` fields that duplicate SessionPool tracking. +- **State fields**: `ServerState` maintains `messages` (canonical message history, 56+ refs), `session_status`, `input_providers`, `pending_questions`, `todos`, `reverted_messages`.

The main message path (`message_routes.py:411`) performs the same mutation: `agent._input_provider = input_provider` on the shared agent.

Splitting into (A) route unification and (B) state consolidation allows incremental delivery, easier rollback, and validation at each milestone. +**Alternative considered**: Single PR with all changes. Rejected due to blast radius and difficulty of debugging failures across all subsystems simultaneously. + +### Decision 2: Streaming endpoints use `SessionPool.run_stream()` with turn lock, not `receive_request()` +**Rationale**: `summarize_session`, `_execute_slashed_command`, and `_execute_skill_command` need event-level access to incrementally build `MessageWithParts` and broadcast `PartDeltaEvent`s. `receive_request()` is fire-and-forget and returns a `RunHandle` (or `None`), denying the caller access to the event stream. For these endpoints, the correct entry point is `SessionPool.run_stream()` (which yields events from an EventBus subscription) or direct EventBus subscription. **Turn isolation is already enforced internally by `SessionPool.run_stream()`**; the caller should NOT acquire `SessionState.turn_lock` manually. +**Alternative considered**: Use `receive_request()` for all endpoints. Rejected because it would break event processing and response construction for streaming endpoints. +**Alternative considered**: Allow streaming endpoints to bypass turn isolation. Rejected because PydanticAI agents are not safe for concurrent runs and concurrent turns would corrupt agent state. + +### Decision 3: Slash commands become SessionPool streaming turns +**Rationale**: `_execute_slashed_command()` calls `agent.run_stream()` for ALL slash commands (both plain and skill) after executing `command.execute()`. Similarly, `_execute_skill_command()` streams via `agent.run_stream()`. Both MUST migrate to `SessionPool.run_stream()` for per-session agent isolation. There is no "non-streaming" slash command path in the current codebase. +**Alternative considered**: Route only skill commands through SessionPool and leave plain commands direct. Rejected because plain commands also invoke `agent.run_stream()` and would continue using the shared agent, perpetuating the state corruption bug. + +### Decision 4: Shell execution remains direct passthrough +**Rationale**: `session_routes.py` directly calls `agent.env.execute_command()`. Routing through the `bash` tool within a SessionPool turn would fundamentally change semantics — shell commands become LLM-mediated operations with latency and potential refusal. Users expect immediate deterministic execution. +**Alternative considered**: Route through SessionPool tool framework. Rejected because it is a UX-breaking product change, not an architecture refactor. + +### Decision 5: Permission handling uses `OpenCodeInputProvider` on `SessionState` +**Rationale**: `ACPInputProvider` uses ACP protocol event schemas that do not match OpenCode's `PermissionRequestEvent`/`PermissionReplyEvent`. OpenCode server already has `OpenCodeInputProvider`. The migration moves it from `ServerState.input_providers[session_id]` to `SessionState.input_provider`. +**Alternative considered**: Use `ACPInputProvider` and adapt events. Rejected because it would break OpenCode client's permission UI. + +### Decision 6: Session CRUD delegates to `SessionController` +**Rationale**: `ServerState.sessions` and `ServerState.session_status` are parallel in-memory caches. `SessionController` already maintains `SessionState` objects with the same metadata. OpenCode session routes should call `SessionController.get_or_create_session()`, `SessionPool.close_session()`, and read session status from `SessionController`. +**Alternative considered**: Keep `ServerState.sessions` as a read-only cache. Rejected because it perpetuates dual-state and risks stale data. + +### Decision 7: SSE event streaming uses EventBus subscriber with replay buffer +**Rationale**: Currently OpenCode SSE produces events from `ServerState.messages[session_id]`. This provides historical message replay for new SSE subscribers. EventBus alone does not buffer events for late subscribers. The migration adds a replay buffer (last N events) to EventBus or `SessionState`. +**Mitigation for bounded buffer**: For sessions with >N messages, new subscribers miss events older than the buffer. During Migration A, `ServerState.messages` is retained as fallback for full history. During Migration B, the message history API (`SessionPool.get_messages()`) provides full historical replay, making the bounded buffer a latency optimization (recent events from buffer) with full history from the API. +**Alternative considered**: Remove historical replay. Rejected because OpenCode clients rely on receiving message history when reconnecting. + +### Decision 8: Replace SessionPool-internal stack inspection with ContextVar; keep AG-UI inspection during Migration A +**Rationale**: `_should_bypass_session_pool()` serves two purposes: (1) deadlock prevention when `TurnRunner._run_turn_unlocked()` internally calls `agent.run_stream()`, and (2) AG-UI direct streaming bypass. Purpose (1) involves detecting SessionPool-internal frames (`_run_turn_unlocked`, `run_loop`, `run_turn`). Replacing this with a `ContextVar` set by TurnRunner before calling `agent._run_stream_once()` handles purpose (1) cleanly. + +**Why `_current_run_ctx_var` is insufficient**: `TurnRunner` already sets `_current_run_ctx_var` for RunContext propagation. However, this ContextVar carries the `RunContext` object (or `None`), not a boolean bypass flag. Reusing it would require `_should_bypass_session_pool()` to check `if _current_run_ctx_var.get() is not None`, but this check would incorrectly return `True` for ALL callers that set a RunContext — including standalone agent callers that are NOT inside SessionPool internals. A dedicated `_bypass_session_pool` ContextVar (boolean) is required to distinguish SessionPool-internal calls (bypass=True) from external calls (bypass=False or unset). + +For purpose (2), AG-UI still needs bypass during Migration A until the B0.4 audit confirms SessionPool compatibility. We use a hybrid approach: ContextVar for TurnRunner, stack inspection for AG-UI during Migration A. In Migration B (B5.1), AG-UI inspection is removed post-audit. +**Alternative considered**: Replace ALL stack inspection with ContextVar. Rejected because AG-UI doesn't set the ContextVar and would break. +**Alternative considered**: Keep all stack inspection. Rejected because SessionPool-internal frame detection is fragile and couples BaseAgent to orchestrator internals. + +### Decision 9: Feature flags for incremental rollout +**Rationale**: Each route category (slash commands, skill commands, init, summarize, MCP prompts) gets a startup-time configuration flag on `agentpool_config.session_pool.OpenCodeConfig` (e.g., `use_session_pool_for_commands: bool`). Flags default to `False` and are read from environment variables (`AGENTPOOL_USE_SESSION_POOL_FOR_COMMANDS`, etc.) at server initialization. Note: `OpenCodeConfig` is frozen (`ConfigDict(frozen=True)`), so flags are set once at startup and require restart to change. This enables gradual enablement in staging and A/B comparison across deployments. +**Alternative considered**: Atomic migration with branch rollback. Rejected because partial failures would require reverting all progress. + +### Decision 10: Post-stream cleanup via `finally` block for streaming endpoints +**Rationale**: `summarize_session` needs to call `compact_conversation()` after the stream completes. Streaming endpoints use `SessionPool.run_stream()` which yields events but does not expose a `RunHandle`. The cleanup is performed in a `finally` block after the `async for` loop over `run_stream()` completes, or by obtaining the per-session agent from `SessionController` after the stream and calling `compact_conversation()` on its conversation. + +### Decision 11: Fix `ensure_session` shared agent mutation +**Rationale**: `session_pool_integration.py` sets `target_agent._input_provider = input_provider` on the shared agent, corrupting state for all sessions. The fix is to store the input provider on `SessionState` only and ensure the per-session agent (via `SessionController.get_or_create_session_agent()`) receives its own input provider. +**Alternative considered**: Leave as pre-existing bug. Rejected because the migration actively exercises this code path and would make the bug more severe. + +### Decision 12: Model switching targets per-session agent via SessionPool +**Rationale**: `_process_message_locked` currently switches the shared agent's model, but SessionPool uses a per-session agent for native agents. The fix is to obtain the per-session agent via `SessionController.get_or_create_session_agent(session_id)` and call `set_model()` on it directly. +**Alternative considered**: Pass the desired model as a parameter to `SessionPool.receive_request()`. Rejected because it would require adding a new parameter to `receive_request()` and doesn't match existing API patterns. +**Alternative considered**: Leave as pre-existing bug. Rejected because it's in the critical message path and the migration must not regress behavior. + +## Risks / Trade-offs + +- **[Risk] Performance regression from EventBus subscription overhead for SSE** → **Mitigation**: EventBus is already used by ACP server; measured overhead is negligible. Subscriber creation is lazy. +- **[Risk] Breaking tests that rely on `ServerState.get_or_create_agent()`** → **Mitigation**: Search and update all test references. Add shim methods that delegate to `SessionPool` during Migration A. +- **[Risk] Slash command behavior change when injected as "asap" vs direct run** → **Mitigation**: "asap" drains before the next model request. Commands that need post-turn execution use `priority="when_idle"`. Add behavior parity tests. +- **[Risk] Message history API design delays Migration B** → **Mitigation**: Migration A delivers value independently. Migration B is blocked only on API design. +- **[Risk] Non-native agents share instances across sessions** → **Mitigation**: Document limitation. Per-session non-native agent support is a follow-up change. +- **[Risk] Double-locking: route-level lock + turn_lock** → **Mitigation**: Evaluate removing route-level `state.get_session_lock(session_id)` once routes are pure SessionPool delegates. Document decision. +- **[Trade-off] ServerState becomes thinner** → `ServerState` will lose agent resolution and some state fields. This is intentional. + +## Migration Plan + +### Migration A: Route Unification + +1. **Phase A1 (Prep)**: Replace `_should_bypass_session_pool()` with `ContextVar`. Verify `input_provider` on `SessionState` is populated correctly (already present in `core.py:86`). Add `SessionController.list_sessions()`, `list_pending_questions()`, `list_pending_permissions()`. Add feature flags on `agentpool_config.session_pool.OpenCodeConfig`. Add shim methods on `ServerState`. Mark `get_or_create_agent()` deprecated. +2. **Phase A2 (Core Routes)**: Verify `send_message` and `send_message_async` already use `SessionPool.receive_request()`. Fix `OpenCodeStreamAdapter` finalization bug. Fix model switching to target per-session agent. Fix `ensure_session` shared agent mutation. +3. **Phase A3 (Streaming Routes)**: Migrate `summarize_session`, `_execute_slashed_command`, `_execute_skill_command` to use `SessionPool.run_stream()` or EventBus subscription (not `receive_request()`). These endpoints need event-level access. +4. **Phase A4 (Fire-and-Forget Routes)**: Migrate `init_session`, MCP prompt commands to use `SessionPool.receive_request()` behind feature flags. Handle background `RunHandle` lifecycle via `SessionController._runs`. +5. **Phase A5 (Permissions)**: Migrate permission handling to `OpenCodeInputProvider` on `SessionState`. Add fast-path Future resolution (HTTP POST sets `asyncio.Future` on `OpenCodeInputProvider`, SSE endpoint awaits it). Update global listing endpoints to query `SessionController`. +6. **Phase A6 (Shell)**: Replace `state.agent.env.execute_command()` with standalone `Env`/`ProcessManager`. Keep direct execution semantics. +7. **Phase A7 (Session CRUD)**: Migrate `list_sessions`, `abort_session`, `get_or_load_session` to use `SessionController`. For `abort_session`, expose per-session agent from `SessionController` for `interrupt()` calls. +8. **Phase A8 (Cleanup)**: Remove `ServerState._session_agents`, `get_or_create_agent()`. Remove route-level locks if redundant. +9. **Phase A9 (Tests)**: Update all OpenCode server tests. Add behavior parity tests. Add integration tests for each migrated endpoint. +10. **Phase A10 (Verification)**: Run full integration test suite. Manual end-to-end tests. Performance benchmarks. Concurrency tests. + +### Migration B: State Consolidation (Blocked on Prerequisite APIs) + +1. **Phase B0 (Prerequisite Design)**: Design message history API. Design global permission/question listing APIs. Design EventBus replay buffer. AG-UI audit. OpenCode client compatibility audit. Decide fate of `todos` endpoints. Contingency planning for audit failures. +2. **Phase B1 (Message History API)**: Implement `SessionPool.get_messages()`, `append_message()`, `truncate_messages()`, `copy_messages()`. +3. **Phase B2 (EventBus Replay)**: Add bounded replay buffer. Implement subscriber replay protocol. +4. **Phase B3 (SSE Migration)**: Update SSE to use EventBus + replay. Verify `OpenCodeEventAdapter`. +5. **Phase B4 (State Cleanup)**: Migrate `share_session()`, `revert_session()`, `get_or_load_session()` to message history API. Remove `messages`, `reverted_messages`, `session_status`, `input_providers`, `pending_questions`, `todos` from `ServerState`. +6. **Phase B5 (BaseAgent Final Cleanup)**: Remove AG-UI bypass post-audit. Remove legacy fallback paths. +7. **Phase B6 (Tests)**: Integration tests for message history API, replay buffer, SSE. +8. **Phase B7 (Verification)**: Manual end-to-end tests.

Note: `use_session_pool` (default `True`, global master switch) already exists in `OpenCodeConfig` at `agentpool_config/session_pool.py:55`; verify it is present and functional. Read values from environment variables (`AGENTPOOL_USE_SESSION_POOL_FOR_*`) when `OpenCodeConfig` is instantiated (via `default_factory` during manifest loading). Document env vars in `docs/configuration/index.md`. +- [ ] A1.5 Define generic `PendingQuestion` and `PendingPermission` Protocol types (or ABCs) in `agentpool/models/` with fields: `id`, `session_id`, `tool_name`, `content`, `created_at`. These are used by `SessionController` APIs. Also define concrete dataclasses `OpenCodePendingQuestion` and `OpenCodePendingPermission` in `agentpool_server/opencode_server/models/question_permission.py` that implement these Protocols. Re-export them via `agentpool_server/opencode_server/models/__init__.py` for route imports. +- [ ] A1.6 Add `SessionController.list_pending_questions() -> list[PendingQuestion]` and `list_pending_permissions() -> list[PendingPermission]` stub methods using the generic Protocol types +- [ ] A1.7 Update `OpenCodeInputProvider` in `input_provider.py` to use the generic `PendingQuestion`/`PendingPermission` Protocol types instead of OpenCode-specific types. Add `event_bus: EventBus` parameter to the constructor (alongside existing `state: ServerState` and `session_id: str`) for future Migration B use — do NOT remove `state` during Migration A. Keep `self.state.broadcast_event()` calls as-is during Migration A because SSE endpoints still consume from `state.event_subscribers`. The `event_bus` parameter is stored on the provider but unused until Migration B when SSE migrates to EventBus-only. Replace `self.state.pending_questions` dict access with an internal `dict[str, PendingQuestion]` stored on the provider instance. Add `get_pending_questions() -> list[PendingQuestion]` method to return all pending questions from the internal dict. Add `cancel_pending_questions() -> list[str]` method to cancel all pending questions and return their IDs (replaces `ServerState.cancel_session_pending_questions()`). +- [ ] A1.8 Add `SessionController.get_session_agent(session_id)` method that returns the per-session agent for native agents, or the shared singleton for non-native agents (with a warning log). Raises `KeyError` if the session has no associated agent. Also set `session.is_per_session_agent: bool` when creating the agent (True for native agents where `session.agent` is a unique instance, False for non-native shared singletons). Add `ServerState` shim methods: `get_session()`, `list_sessions()`, `get_session_status()` that delegate to `SessionController`. Store a direct `SessionController` reference on `ServerState` during initialization: add `session_controller: SessionController | None = field(default=None, repr=False)` to the `ServerState` dataclass. Update the production call site that constructs `ServerState` (in `server.py`) to pass the `SessionController`. Tests that construct `ServerState` without passing `session_controller` will use the default `None` and continue to work during Migration A. **These shim methods are temporary and removed in Migration B when ServerState is fully cleaned up.** +- [ ] A1.9 Verify `SessionState.is_per_session_agent` field (already exists in `agentpool/orchestrator/core.py:79`) is set to `True` by `SessionController.get_or_create_session_agent()` when creating native per-session agents. No code changes needed if already implemented; add regression test if missing. +- [ ] A1.10 Add `SessionController.list_sessions() -> list[SessionState]` stub method (returns `list(self._sessions.values())`) so shim methods in A1.8 can compile immediately +- [ ] A1.11 Add `warnings.warn("Use SessionController.get_or_create_session_agent()", DeprecationWarning)` to `ServerState.get_or_create_agent()` (already has deprecation docstring; this adds the runtime warning) +- [ ] A1.12 Replace TOCTOU `get_session() is None` + `create_session()` patterns with `SessionController.get_or_create_session()` in route handlers. **IMPORTANT**: Only replace patterns that call `session_pool.create_session()` (on the `SessionPool` instance) or `session_pool.sessions.get_or_create_session()` directly. Do NOT replace calls to `integration.create_session()` / `self.create_session()` (on `OpenCodeSessionPoolIntegration`) — these are OpenCode-specific and also start the `SessionStatusBridge` and `_event_consumer_loop`, which `SessionController.get_or_create_session()` does NOT do. The integration methods are refactored separately in A1.14. +- [ ] A1.13 Modify `SessionController.get_or_create_session()` to return `tuple[SessionState, bool]` where the bool indicates whether the session was newly created (True) or already existed (False). Update all existing call sites of `get_or_create_session()` to unpack the tuple. **IMPORTANT**: Also update `SessionPool.create_session()` (in `agentpool/orchestrator/core.py:1481`) to unpack the tuple returned by `self.sessions.get_or_create_session()` and return just the `SessionState` for backward compatibility with non-OpenCode callers (ACP, teams, base_agent, etc.). +- [ ] A1.14 Refactor `OpenCodeSessionPoolIntegration.create_session()` (and any other integration methods that start bridge/consumer) to: (1) call `SessionController.get_or_create_session()` and check the returned boolean, then (2) start `SessionStatusBridge` and `_event_consumer_loop` only if the session was newly created. Ensure bridge/consumer startup is NOT skipped during the A1.12 migration. +- [ ] A1.15 In OpenCode server routes, after calling `SessionController.get_or_create_session()`, unpack the returned tuple: `session, was_created = SessionController.get_or_create_session(...)`. Set `session.input_provider = OpenCodeInputProvider(state=state, session_id=session_id, event_bus=session_pool.event_bus)` for OpenCode sessions. The `was_created` boolean can be used by routes to conditionally run setup logic. Do NOT modify generic `SessionController.get_or_create_session()` — keep protocol-specific initialization in protocol routes. +- [ ] A1.16 Inventory all tests touching `ServerState` dicts — run `pytest --collect-only` filtered by `opencode_server`; output the test list to `tests/opencode_server_test_inventory.md` for reference during Migration A +- [ ] A1.17 Add test: `BaseAgent.run_stream()` emits `DeprecationWarning` and delegates to `SessionPool` (already implemented; this test prevents regression) +- [ ] A1.18 Define feature flag interaction logic: category flags (`use_session_pool_for_*`) are only evaluated when the global `use_session_pool` flag is `True`. If `use_session_pool=False`, all SessionPool routing is disabled regardless of category flags. Document this in `agentpool_config/session_pool.py` and `docs/configuration/index.md`. +- [ ] A1.19 Add `scope: str = "session"` as a **keyword-only** parameter after `*prompts` in `SessionPool.run_stream()` signature: `async def run_stream(self, session_id: str, *prompts: str, scope: str = "session", **kwargs: Any)`. Pass `scope` through to `self.event_bus.subscribe(session_id, scope=scope)`. This allows streaming endpoints that invoke subagents to call `run_stream(session_id, "prompt", scope="descendants")` without breaking existing call sites. Update all existing call sites of `run_stream()` to use the default (no code change needed for backward compatibility). + +### A2. Fix Pre-Existing Bugs in Core Routes + +- [ ] A2.1 Fix shared agent `_input_provider` mutation in `session_pool_integration.py` (both `ensure_session` at line 162 and `_create_and_persist_session` at line 250) and `message_routes.py:411`. Store input provider on `SessionState` only and ensure per-session agents receive their own input provider via `SessionController`. +- [ ] A2.2 Fix model switching in `_process_message_locked`: obtain per-session agent from `SessionController.get_or_create_session_agent(session_id)` and call `set_model()` on it directly +- [ ] A2.3 Fix orphaned `OpenCodeStreamAdapter` in `_process_message_locked`: the adapter is created at line 368 but neither `process_stream()` nor `convert_event()` is ever called in that function, so `adapter.finalize()` (line 541) produces a `StepFinishPart` with zero tokens. The background `_event_consumer_loop` uses its own separate `EventProcessorContext` and adapter. Fix: connect the adapter in `_process_message_locked` to the event flow by either (a) passing it to the event consumer loop so the same adapter instance receives events, or (b) calling `adapter.convert_event()` in the consumer loop for events belonging to this session. After the fix, `run_handle.complete_event.wait()` guarantees the turn has finished before `adapter.finalize()` is called. Add test verifying adapter receives all events before finalize and that finalize produces non-zero tokens. +- [ ] A2.4 Add route-level `state.get_session_lock(session_id)` for ALL endpoints that perform multi-phase operations (stream + post-process): `summarize_session`, `_execute_slashed_command`, `_execute_skill_command`. These endpoints call `SessionPool.run_stream()` and then perform post-stream work (e.g., `compact_conversation`, `state.broadcast_event()`). Without route-level locks, concurrent requests could interleave. **Lock ordering rule**: route-level lock is acquired FIRST, then `SessionPool.run_stream()` acquires `turn_lock` internally. This ordering is safe because route-level locks are per-session and `turn_lock` is also per-session — a single thread of execution holds both, so no circular wait can occur. Evaluate removal only for single-phase endpoints (e.g., `send_message` which is fully handled by SessionPool). Document the decision in `docs/opencode-server/locks.md`. +- [ ] A2.5 Remove dead `agent.session_id` fallback in `StreamEventEmitter._emit()`: `_emit()` should read `session_id` from `run_ctx.session_id` directly and not check `getattr(self._context.agent, "session_id", None)` first. Add test verifying `_emit()` uses `run_ctx.session_id`. + +### A3. Migrate Streaming Endpoints (Need Event-Level Access) + +- [ ] A3.1 Migrate `summarize_session()` to use `SessionPool.run_stream()` (not `receive_request()`) behind `use_session_pool_for_summarize` flag — endpoint needs `PartStartEvent`, `PartDeltaEvent`, `StreamCompleteEvent` to build text parts and extract token usage. Turn isolation is handled internally by SessionPool. +- [ ] A3.2 Add post-stream cleanup for `summarize_session()`: after `SessionPool.run_stream()` completes (async for loop finishes), obtain the per-session agent via `SessionController.get_or_create_session_agent(session_id)`, get `agent.conversation`, and call `compact_conversation(pipeline, agent.conversation)` in a `finally` block or after loop exit. Add test verifying compact_conversation runs after stream completion. +- [ ] A3.3 Migrate `_execute_slashed_command()` to use `SessionPool.run_stream(session_id, scope="descendants", ...)` behind `use_session_pool_for_commands` flag — plain slash commands call `command.execute()` and then `agent.run_stream()` to process the loaded skill context. The entire function must route through SessionPool. Use `scope="descendants"` because slash commands may invoke subagent tools that create child sessions; child session events must be visible in the parent stream. Turn isolation is handled internally by SessionPool. +- [ ] A3.4 Migrate `_execute_skill_command()` to use `SessionPool.run_stream(session_id, scope="descendants", ...)` behind `use_session_pool_for_skills` flag — same adapter pattern as slash skill commands. Use `scope="descendants"` because skill commands may invoke subagent tools that create child sessions. Turn isolation is handled internally by SessionPool. +- [ ] A3.5 Implement `OpenCodeEventBridge` in `agentpool_server/opencode_server/event_bridge.py`: instantiate one bridge per `ServerState` in `ServerState.__post_init__()` only when `self.session_controller is not None` (skip bridge creation in tests that don't pass a controller). Pass `self` and `self.session_controller` to the bridge constructor. Routes access it via `state.event_bridge.broadcast_event(event)` instead of `state.broadcast_event(event)`. The bridge method: (1) calls the original `state.broadcast_event(event)` to maintain backward compatibility with `state.event_subscribers` (which SSE still consumes from during Migration A), (2) converts OpenCode protocol events (`MessageUpdatedEvent`, `PartUpdatedEvent`, `SessionStatusEvent`, etc.) to `RichAgentStreamEvent` wrappers, (3) republishes them to EventBus via `session_pool.event_bus.publish(session_id, wrapped_event)`. During Migration A, the bridge ensures EventBus contains both agent events and protocol events *in preparation for* Migration B (when SSE will migrate to EventBus-only). SSE subscribers continue to receive events through `state.event_subscribers`, not EventBus. Add test verifying bridge republishes protocol events to EventBus. +- [ ] A3.6 Add behavior parity tests for streaming endpoints comparing legacy vs SessionPool paths + +### A4.

Migrate Session CRUD and Cleanup + +- [ ] A7.1 Migrate `get_or_load_session()` to use `SessionController.get_or_create_session_agent()` instead of `ServerState.get_or_create_agent()` +- [ ] A7.2 Define `SessionInfo` DTO in `agentpool_server/opencode_server/models/session_info.py` with fields: `session_id: str`, `status: str`, `created_at: float`, `last_activity: float`, `message_count: int`. Re-export via `agentpool_server/opencode_server/models/__init__.py`. Update the existing `SessionController.list_sessions()` stub (added in A1.10) to return `list[SessionInfo]` with conversion logic from `SessionState` to `SessionInfo`. **For `message_count` during Migration A**: read from `ServerState.messages[session_id]` since `SessionState` does not yet track message history (this is temporary until Migration B implements `SessionPool.get_messages()`). Update `ServerState.list_sessions()` shim (added in A1.8) to delegate to the updated method. Migrate `list_sessions` route to use the DTO. +- [ ] A7.3 Use `SessionController.get_session_agent(session_id)` (added in A1.8) in route handlers. For non-native (shared) agents, the method returns the shared instance with a warning log. Raises `KeyError` if the session has no associated agent (e.g., session was created but no turn has run yet). +- [ ] A7.4 Migrate `abort_session` to use `SessionController.get_session_agent(session_id)` and call `interrupt()` for native agents only. Use `session.is_per_session_agent` (True for native agents with dedicated instances, False for non-native shared singletons) to determine whether `interrupt()` is safe. For non-native shared agents (`session.is_per_session_agent == False`), cancel the RunHandle without calling `interrupt()` (to avoid killing all sessions using that agent). Obtain the active `run_id` from `session.current_run_id` via `SessionController.get_session(session_id)`, then cancel the associated `RunHandle` via `SessionPool.cancel_run(run_id)`. +- [ ] A7.5 Remove `ServerState._session_agents` cache entirely +- [ ] A7.6 Remove deprecated `ServerState.get_or_create_agent()` entirely +- [ ] A7.7 Audit `ServerState` for any remaining direct agent references; replace with SessionPool delegation + +### A8.

OpenCode server to SessionPool This commit implements Migration A of the OpenCode-to-SessionPool migration plan, migrating non-chat endpoints to use SessionPool behind feature flags while preserving full backward compatibility. Core Changes: - ContextVar bypass mechanism in BaseAgent for SessionPool internal calls - 5 category feature flags (commands, skills, init, summarize, mcp) in OpenCodeConfig - Generic PendingQuestion/PendingPermission Protocol types - SessionController listing APIs + ServerState shim methods - get_or_create_session() now returns tuple[SessionState, bool] Streaming Routes (SessionPool.run_stream()): - summarize_session: migrated behind use_session_pool_for_summarize flag - slash commands: migrated behind use_session_pool_for_commands flag - skill commands: migrated behind use_session_pool_for_skills flag - OpenCodeEventBridge for dual-path event broadcasting (SSE + EventBus) Fire-and-Forget Routes (SessionPool.receive_request()): - init_session: migrated behind use_session_pool_for_init flag - MCP prompt commands: migrated behind use_session_pool_for_mcp flag Session CRUD: - SessionInfo DTO for typed session listings - abort_session: agent-aware (native vs non-native) via SessionController - Removed deprecated ServerState methods (get_or_create_agent, _session_agents, remove_session_agent) Bug Fixes: - Fixed shared agent _input_provider mutation (now stored on SessionState) - Fixed model switching to target per-session agent - Fixed orphaned OpenCodeStreamAdapter event processing - Added route-level locks for multi-phase endpoints Other: - Shell execution uses standalone Env/ProcessManager - Permissions and questions migrated to SessionState.input_provider - 55 migration-specific tests added, all passing - 7 obsolete test files removed - Full backward compatibility: all flags default to False Refs: migrate-opencode-to-sessionpool plan --- docs/audit/agui-bypass-audit.md | 222 +++++ docs/audit/opencode-client-audit.md | 163 ++++ docs/configuration/index.md | 10 + docs/decisions/todos-endpoints.md | 105 +++ docs/design/eventbus-replay.md | 271 ++++++ docs/design/message-history-api.md | 346 ++++++++ docs/design/permission-question-api.md | 294 +++++++ .../migrate-opencode-to-sessionpool/tasks.md | 12 +- scripts/qa_test_server.py | 169 ++++ src/agentpool/agents/base_agent.py | 35 +- src/agentpool/models/__init__.py | 3 + src/agentpool/models/pending_interaction.py | 56 ++ src/agentpool/orchestrator/core.py | 135 ++- src/agentpool_config/session_pool.py | 50 ++ .../opencode_server/event_bridge.py | 137 +++ .../opencode_server/input_provider.py | 23 +- .../opencode_server/models/__init__.py | 8 + .../models/question_permission.py | 60 ++ .../opencode_server/models/session_info.py | 26 + .../opencode_server/routes/agent_routes.py | 5 +- .../opencode_server/routes/config_routes.py | 11 -

This was introduced so that protocol layers (opencode server, ACP server) could distinguish events belonging to child sessions from those of the parent session. + +However, this design has several problems: + +1. **Runner layer overreach**: The runner should not know about subagent hierarchies. Its job is to execute agents and emit raw events. Session hierarchy is a protocol-layer concern. + +2. **Event transparency loss**: Components like `BackgroundTaskProvider._task_sync` expect to match raw completion events (`StreamCompleteEvent`, `ToolCallStartEvent`) from the event stream. When these are wrapped inside `SubAgentEvent`, the match logic fails, causing the lead agent to hang waiting for a result that was already emitted. + +3. **Redundancy**: Both opencode and ACP servers already use `scope="descendants"` to subscribe to child session events on the EventBus. They receive child events directly — the `SubAgentEvent` wrapping is an extra layer that duplicates what the EventBus scope mechanism already provides. + +4. **ACP complexity**: The ACP event converter has three subagent display modes (inline, tool_box, legacy) that depend on `SubAgentEvent` to extract `source_name` and `depth`.

Subject: [PATCH 26/51] fix(agent): add fallback for inject_prompt when session_id is missing When BackgroundTaskProvider completes a background task and calls ctx.agent.inject_prompt(notice), if the agent has no active run context and no fixed session_id (common for shared agents), the message was silently dropped. This fix adds a fallback mechanism in BaseAgent.inject_prompt: 1. When effective_session_id is None but session_pool exists, search for the most recently active session associated with this agent 2. Route the message to that session via session_pool.receive_request to trigger auto-resume Changes: - SessionController.find_sessions_by_agent_name(): new method to find active sessions for a given agent - BaseAgent.inject_prompt(): added fallback in both native and legacy paths when effective_session_id is None - test_shared_agent_inject_prompt_fallback_triggers_auto_resume: new integration test simulating the BackgroundTaskProvider scenario --- src/agentpool/agents/base_agent.py | 50 ++++++++--- src/agentpool/orchestrator/core.py | 13 +++ .../orchestrator/test_integration_redflags.py | 85 +++++++++++++++++++ 3 files changed, 137 insertions(+), 11 deletions(-) diff --git a/src/agentpool/agents/base_agent.py b/src/agentpool/agents/base_agent.py index b85d39fdd..9eb133b34 100644 --- a/src/agentpool/agents/base_agent.py +++ b/src/agentpool/agents/base_agent.py @@ -73,7 +73,9 @@ from agentpool_config.mcp_server import MCPServerConfig # Union type for state updates emitted via state_updated signal - type StateUpdate = ModeInfo | ModelInfo | AvailableCommandsUpdate | ConfigOptionChanged | ToastInfo + type StateUpdate = ( + ModeInfo | ModelInfo | AvailableCommandsUpdate | ConfigOptionChanged | ToastInfo + ) # ContextVar for per-execution isolation of _current_run_ctx (RFC-0021 compliance) @@ -276,8 +278,7 @@ def __init__( self._input_provider = input_provider if input_provider is not None: warnings.warn( - "BaseAgent._input_provider is deprecated.

Removing `ClaudeAgentConfig`, `AGUIAgentConfig`, `CodexAgentConfig` from the union will cause type errors that guide the rest of the cleanup. This is safer than deleting implementation files first. +**Alternative considered**: Delete implementation files first, then fix config. Rejected because it leads to cascading import errors that are harder to trace. + +### Decision 2: Keep `file` agent as config-only mechanism +**Rationale**: `file_agents` is not a runtime agent type but a YAML config loading mechanism that reads agent definitions from files. It has no dedicated agent implementation. Removing it would break config inheritance patterns. +**Alternative considered**: Remove entirely. Rejected because it would break legitimate config composition use cases. + +### Decision 3: Remove deprecated code before agent types +**Rationale**: Deprecated code (`MCPManager`, `ToolManager`, `AgentHooks`, `connect_to()`, etc.) has no production callers and minimal test coverage. Removing it first reduces noise when refactoring agent types. +**Alternative considered**: Remove agents first. Rejected because deprecated code imports may reference agent types, creating circular cleanup work. + +### Decision 4: Do not create migration shim for removed agents +**Rationale**: This is a major version bump change. Users with claude/agui/codex configs will need to update their YAML. A shim would perpetuate the debt we're trying to eliminate. +**Alternative considered**: Add deprecation warnings for one release cycle. Rejected because it defeats the purpose of a clean break. + +### Decision 5: Remove orphaned dependencies in a single `pyproject.toml` pass +**Rationale**: Dependencies like `claude-sdk`, `agui-sdk`, `codex-sdk`, and `tiktoken` will have no importers after agent removal. A single pass keeps the dependency graph clean. +**Alternative considered**: Remove incrementally. Rejected because it creates intermediate broken states. + +## Risks / Trade-offs + +- **[Risk]** Import chains from core modules to removed agents may be non-obvious → **Mitigation**: Use type checker (mypy) and test suite to catch all references.

Patterns +#### ProtocolEventConsumerMixin + +`ProtocolEventConsumerMixin` (in `src/agentpool_server/mixins.py`) provides a reusable event consumer lifecycle for protocol servers. It extracts the common pattern of subscribing to the `EventBus`, running an async consumer loop, and cleaning up on shutdown. + +**Why it exists**: Before this mixin, OpenCode and ACP each implemented their own event consumer loop independently. The code was duplicated, and ACP's implementation was missing features like `SpawnSessionStart` handling and recursive child subscription. The mixin centralizes the loop mechanics while letting each protocol define its own event conversion. + +**Which protocols use it**: +- **ACP** (`acp_server/handler.py`): Adopted in Phase 1. Uses `scope="descendants"` to receive child events through the parent consumer. `_on_spawn_session_start` is a no-op because ACP does not create child consumers. +- **OpenCode** (`opencode_server/session_pool_integration.py`): NOT yet adopted (Phase 2, future change). The mixin interface was designed to be compatible with OpenCode's needs (ToolPart registration, child consumer creation, `OpenCodeEventAdapter`). +- **AG-UI / OpenAI API**: NOT yet adopted. Can adopt the mixin when subagent event forwarding is needed. + +**Key hooks**: +- `_before_consumer_loop(session_id)`: Set up per-session context (e.g. create an event converter). +- `_handle_event(session_id, event)`: Convert and deliver the event. May raise `ConsumerShutdown` to stop the loop. +- `_on_spawn_session_start(session_id, event)`: React to subagent spawning. Default is no-op. +- `_after_consumer_loop(session_id)`: Clean up per-session context. Only called if the consumer actually started. + +**Thread safety**: `start_event_consumer` is idempotent and serializes concurrent calls for the same session via per-session locks. + #### MessageNode Abstraction All processing units (Agents, Teams) inherit from `MessageNode[TInputType, TOutput]`. This provides: - Unified interface for message processing via `process()` diff --git a/openspec/changes/auto-subscribe-subagent-events/design.md b/openspec/changes/auto-subscribe-subagent-events/design.md index e8f0be692..b82bcd5fd 100644 --- a/openspec/changes/auto-subscribe-subagent-events/design.md +++ b/openspec/changes/auto-subscribe-subagent-events/design.md @@ -1,83 +1,138 @@ ## Context -当前 AgentPool 中所有子代理委派机制在切换到 SessionPool 路径时，事件路由存在问题： +当前 AgentPool 有两个协议服务器需要消费 SessionPool 的 EventBus 事件： -- **SessionPool 路径**（`session_pool.process_prompt()`）：事件通过 EventBus 发布，但**没有人将 EventBus 事件转发给前端** -- **Legacy 路径**（`node.run_stream()`）：业务层手动将事件包装为 `SubAgentEvent` 发射给前端，**正常工作** +- **OpenCode Server** (`session_pool_integration.py`): 已有完整的事件消费者实现，包括递归子代理订阅和 SpawnSessionStart 处理 +- **ACP Server** (`handler.py`): 只有基础的事件消费者，缺少 SpawnSessionStart 检测、递归订阅、统一的错误处理 -受影响的委派机制包括： -- `BackgroundTaskProvider` — 后台任务（`_task_async` 使用 SessionPool 路径） -- `DelegationProvider` — 同步委派（当前使用 Legacy 路径，但计划切换到 SessionPool） -- 任何使用 SessionPool 运行子代理的工具或流程 -
