From 518677116998e199bb003511d55ec86dc2dd984b Mon Sep 17 00:00:00 2001 From: openhands Date: Sat, 28 Feb 2026 19:02:51 +0000 Subject: [PATCH 1/6] tui: replay historical events on resume/switch (#v0.01) When resuming a conversation via --resume or switching via /history, historical events are now replayed through the ConversationVisualizer so the user sees the full conversation history in the TUI. Changes: - Add ConversationVisualizer.replay_events() for side-effect-free replay (skips critic handling, telemetry, plan panel refreshes; renders user messages inline) - Add ConversationRunner.replay_historical_events() with idempotence guard - Trigger replay in RunnerRegistry.get_or_create() for newly created runners - Add 7 unit tests covering replay order, empty/idempotent cases, and registry integration Verified: make lint, make test (1268 passed), make test-snapshots (59 passed) Co-authored-by: Ironbelly Ryan Co-authored-by: openhands --- openhands_cli/tui/core/conversation_runner.py | 22 ++++++ openhands_cli/tui/core/runner_registry.py | 4 + .../tui/widgets/richlog_visualizer.py | 48 ++++++++++++ .../core/test_conversation_runner_replay.py | 78 +++++++++++++++++++ tests/tui/core/test_runner_registry.py | 65 ++++++++++++++++ 5 files changed, 217 insertions(+) create mode 100644 tests/tui/core/test_conversation_runner_replay.py create mode 100644 tests/tui/core/test_runner_registry.py diff --git a/openhands_cli/tui/core/conversation_runner.py b/openhands_cli/tui/core/conversation_runner.py index 9d4182409..08eee3c49 100644 --- a/openhands_cli/tui/core/conversation_runner.py +++ b/openhands_cli/tui/core/conversation_runner.py @@ -80,6 +80,7 @@ def __init__( ) self._running = False + self._historical_events_replayed = False # State for reading (is_confirmation_active) and updating (set_running) self._state = state @@ -266,6 +267,27 @@ def pause_runner_without_blocking(self): if self.is_running: asyncio.create_task(self.pause()) + def replay_historical_events(self) -> int: + """Replay historical events from the conversation into the visualizer. + + Iterates conversation.state.events and renders them via the visualizer's + replay_events() method, which skips side effects (critic, telemetry). + + Returns: + Count of replayed events, or 0 if already replayed or empty. + """ + if self._historical_events_replayed: + return 0 + + self._historical_events_replayed = True + + events = list(self.conversation.state.events) + if not events: + return 0 + + self.visualizer.replay_events(events) + return len(events) + def get_conversation_summary(self) -> tuple[int, Text]: """Get a summary of the conversation for headless mode output. diff --git a/openhands_cli/tui/core/runner_registry.py b/openhands_cli/tui/core/runner_registry.py index 81389043f..7cbaddbc5 100644 --- a/openhands_cli/tui/core/runner_registry.py +++ b/openhands_cli/tui/core/runner_registry.py @@ -50,6 +50,10 @@ def get_or_create(self, conversation_id: uuid.UUID) -> ConversationRunner: ) self._runners[conversation_id] = runner + # Replay historical events for newly created runners (resume / switch). + # This is a no-op for brand-new conversations with no events. + runner.replay_historical_events() + if runner.conversation is not None: self._state.attach_conversation_state(runner.conversation.state) diff --git a/openhands_cli/tui/widgets/richlog_visualizer.py b/openhands_cli/tui/widgets/richlog_visualizer.py index 817e82e2c..ffbe7ac4f 100644 --- a/openhands_cli/tui/widgets/richlog_visualizer.py +++ b/openhands_cli/tui/widgets/richlog_visualizer.py @@ -10,6 +10,7 @@ from rich.text import Text from textual.widgets import Markdown +from openhands.sdk import TextContent from openhands.sdk.conversation.visualizer.base import ConversationVisualizerBase from openhands.sdk.event import ( ActionEvent, @@ -855,3 +856,50 @@ def _create_event_collapsible(self, event: Event) -> Collapsible | None: return self._make_collapsible( content_string, f"{agent_prefix}{title}", event ) + + def replay_events(self, events: list[Event]) -> None: + """Replay historical events into the UI without triggering side effects. + + Unlike on_event(), this skips critic handling, telemetry, and plan panel + refreshes.

(#v0.02) BUG-001 (High): --resume shows blank screen instead of conversation history - Add ensure_runner() to ConversationManager that eagerly calls RunnerRegistry.get_or_create(), triggering replay_historical_events() - Store _is_resume flag in OpenHandsApp.__init__ - Call ensure_runner() in _initialize_main_ui() after set_loaded_resources() and before _process_queued_inputs() (ordering constraint) BUG-002 (Medium): Rapid clicking in /history panel crashes the app - Wrap self.screen.get_selected_text() in on_mouse_up with try/except - KeyError from Toast widgets in transient lifecycle states is now caught - References upstream Textual issue #5646 BUG-003 (Medium): --resume last throws ValueError instead of resuming - Add 3-line normalization at top of handle_resume_logic(): detect args.resume.lower() == last, set args.last = True, args.resume = - Case-insensitive: last, LAST, Last all work BUG-004 (Low): UnicodeDecodeError in containerized terminals - Documented as upstream Textual issue in .dev/KNOWN_ISSUES.md - No code change; includes reproduction steps and workaround BUG-005 (Low): RequestsDependencyWarning on stderr at launch - Add targeted warnings.filterwarnings() before third-party imports - Add E402/I001 per-file-ignore for entrypoint.py in pyproject.toml Test coverage: - tests/test_entrypoint.py: 5 new tests (--resume last normalization) - tests/tui/test_auto_copy.py: 1 new test (exception-path for BUG-002) - tests/tui/core/test_conversation_manager.py: 2 new tests (ensure_runner) Files changed: 3 source, 1 config, 1

Also handles `SystemPromptEvent`, `PauseEvent`, `Condensation`, `CondensationRequest` (via `SharedEventHandler`), plus `UserRejectObservation` and `AgentErrorEvent` (→ tool call failed status). +- Skips `ConversationStateUpdateEvent` (internal state, not forwarded to client). + +**Path B: Streaming (`TokenBasedEventSubscriber` in `events/token_streamer.py`)** +- Used when `streaming_enabled=True` AND `not agent.llm.uses_responses_api()`. +- Two entry points from separate source threads: + 1. **Token-level**: `on_token(chunk)` from LLM streaming → `_schedule_update()` → `run_coroutine_threadsafe` → real-time `AgentMessageChunk` updates. + 2. **Event-level**: `sync_callback(event)` from SDK callback thread → `token_subscriber.unstreamed_event_handler(event)` — handles completed events after streaming finishes and resets header state for next response. +- Uses `ToolCallState` (`events/tool_state.py`) per streaming tool call to track incremental arg parsing with `has_valid_skeleton` gate (prevents flickering). + +**`SharedEventHandler` (`events/shared_event_handler.py`)** +- Shared logic used by both subscriber types via the `_ACPContext` protocol. +- Handles: `ThinkAction` → thought text, `FinishAction` → agent message, other actions → `start_tool_call(...)`, observations (except Think/Finish observations) → `send_tool_progress(...)`, `TaskTrackerObservation` → `AgentPlanUpdate`. + +### 1.5 Thread Bridging Pattern + +The SDK's `conversation.run()` is synchronous and executes in a worker thread.

Both default to `~/.openhands`. +- Additional env vars affect derived paths: `OPENHANDS_CONVERSATIONS_DIR` overrides the conversations directory (default: `{persistence_dir}/conversations`), and `OPENHANDS_WORK_DIR` overrides the working directory used for skill loading (default: `cwd`). +- `mcp.json` has no dedicated env override — it inherits `OPENHANDS_PERSISTENCE_DIR`. + +### 2.2 What Is Persisted vs. Derived at Runtime + +| Field | Persisted? | Source | +|---|---|---| +| `agent.llm` (model, api_key, base_url, timeout) | **Yes** — `agent_settings.json` | User setup or settings screen | +| `agent.condenser` | **Yes** — `agent_settings.json` | Created alongside LLM | +| `agent.tools` | **No** — derived | `base_state.json` (resume) or `get_default_cli_tools()` (new) | +| `agent.mcp_config` | **No** — derived | `~/.openhands/mcp.json` via `list_enabled_servers()` | +| `agent.agent_context` | **No** — derived | `load_project_skills(get_work_dir())` + OS description | +| `agent.critic` | **No** — derived | Auto-derived from `llm.base_url` pattern match | +| `agent.llm.litellm_extra_body` | **No** — derived | Added if using OpenHands proxy | +| Hooks (`HookConfig`) | **No** — read each time | `hooks.json` loaded in `setup_conversation()` | + +### 2.3 Why Tools Are in `base_state.json`, Not `agent_settings.json` + +Tools must match the conversation they were created with. From the code: + +> "When resuming a conversation, we should use the tools that were available when the conversation was created, not the current default tools. This ensures consistency and prevents issues with tools that weren't available in the original conversation (e.g., delegate tool)." + +The mechanism: +1. At conversation creation, the SDK writes `base_state.json` with the tool list. +2. On resume, `AgentStore._resolve_tools(session_id)` calls `get_persisted_conversation_tools(conversation_id)` which reads that file. +3. For new conversations, `get_default_cli_tools()` provides: `TerminalTool`, `FileEditorTool`, `TaskTrackerTool`, `DelegateTool`. + +### 2.4 Complete Load Chain + +``` +entrypoint.py: main() + └─ textual_app.main() + └─ OpenHandsApp.__init__() + ├─ CliSettings.load() # reads cli_config.json + │ └─ _migrate_legacy_settings() # auto-saves if migrated + ├─ ConversationContainer( + │ initial_confirmation_policy=..., + │ initial_critic_settings=cli_settings.critic) + ├─ RunnerFactory(env_overrides_enabled, critic_disabled, ...) + └─ ConversationManager(state, runner_factory, store_service, ...) + └─ RunnerRegistry(factory=runner_factory, ...) + + [User sends first message OR resume ID provided] + + RunnerRegistry.get_or_create(conversation_id) + └─ RunnerFactory.create(conversation_id, ...) + └─ ConversationRunner.__init__() + └─ setup_conversation(conversation_id, ...) # module fn in setup.py + ├─ load_agent_specs(session_id, ...) + │ └─ AgentStore().load_or_create(session_id, ...) + │ │ + │ ├─ load_from_disk() → Agent from agent_settings.json + │ ├─ [if --override-with-envs] → apply LLM_API_KEY/MODEL/BASE_URL + │ └─ _apply_runtime_config(): + │ ├─ _resolve_tools() → base_state.json or defaults + │ ├─ _with_llm_metadata() → litellm_extra_body if proxy + │ ├─ _build_agent_context()→ skills + OS info + │ ├─ list_enabled_servers()→ mcp.json + │ ├─ _maybe_build_condenser() → re-tag condenser LLM metadata + │ └─ CliSettings.load() → get_default_critic() + │ → regex match → APIBasedCritic or None + ├─ HookConfig.load(get_work_dir()) → hooks.json + └─ Conversation(agent, workspace, persistence_dir, hook_config, ...) + └─ runner.replay_historical_events() # no-op for new; replays on resume/switch +``` + +### 2.5 Env Overrides + +When `--override-with-envs` is passed: +- `LLM_API_KEY`, `LLM_BASE_URL`, `LLM_MODEL` are read from environment. +- If persisted agent exists: partial override allowed (e.g., only API key). +- If no persisted agent: both `LLM_API_KEY` and `LLM_MODEL` required (raises `MissingEnvironmentVariablesError`). +- Overrides are **never persisted** to disk. + +### 2.6 Migration Path for New Settings Fields + +**`CliSettings` / `CriticSettings`**: Add field with default value.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements v0.03 tasklist (17 tasks, 3 phases, 5 milestones) derived from the v0.02 post-release adversarial review. Phase 0 — CI Green Baseline: - Fix ruff-format and pycodestyle E402 violations in entrypoint.py by collapsing the BUG-005 warnings.filterwarnings() call and adding # noqa: E402 to 7 third-party imports that follow it. The interleaved placement is intentional — the filter must be active before any transitive import of `requests`. - Snapshot mismatch (test_phase5_landing_screen) investigated: passes locally, CI failure is environment-specific (Python 3.12.12 vs 3.12.3 rendering delta). No SVG change required on this branch. Phase 1, M1 — Registry Replay Invariant: - Reorder get_or_create() so the runner is cached in self._runners ONLY after replay_historical_events() completes. If replay raises, no partially-initialized runner pollutes the registry. - Add docstring documenting main-thread constraint and cache invariant. - Add 2 new tests: replay failure leaves cache empty + exception propagates to caller. - Grep verification confirms replay_historical_events call sites match expectations (runner_registry.py call, conversation_runner.py def). Phase 1, M2 — Visualizer Replay Test Coverage: - Create tests/tui/widgets/test_richlog_visualizer_replay.py with 8 tests: T-1: single user message → Static widget with user-message CSS class T-2: observation event routes through _handle_observation_event T-3: multiple pairs render in correct order T-4: scroll_end(animate=False) called exactly once after all events T-5: empty event list → no widgets, no scroll, no exception T-6: critic handling intentionally omitted (regression guard) T-7: telemetry intentionally omitted (regression guard) T-8: plan panel refresh intentionally omitted (regression guard) Phase 1, M3 — Documentation Corrections: - Update ConversationManager class docstring to name ensure_runner() and reload_visualizer_configuration() as synchronous direct-call paths that bypass message-based dispatch for startup ordering reasons. - No exclusive-dispatch language ("only", "exclusively", "always") found in message-dispatch context across codebase or docs. Phase 2, M4 — Integration Validation: - Full suite: 1286 passed, 0 failures. - replay_events() branch coverage ~80% (key paths covered). - Grep constraint holds — no drift from Phase 1 baseline. Context — PR feedback addressed vs. pushed back: ADDRESSED (from v0.02 adversarial review): 1. Registry cache-before-replay ordering bug: The reviewer correctly identified that caching a runner before replay completes could leave a partially-initialized runner in the registry if replay throws. Fixed by reordering (T01.01) and adding regression tests (T01.02). 2. Missing replay test coverage: Zero tests existed for replay_events(). The reviewer's 8-scenario test matrix (T-1 through T-8) was adopted verbatim. These now guard rendering order, scroll behavior, and intentional side-effect omissions. 3. Misleading ConversationManager docstring: The reviewer flagged that the docstring implied message-based dispatch was the exclusive coordination mechanism, when ensure_runner() and reload_visualizer_configuration() are synchronous direct calls. Fixed with qualified language. 4. E402 lint violations: Pre-existing CI failure in entrypoint.py. Added noqa: E402 since the interleaving is intentional (BUG-005). PUSHED BACK (deferred or declined): 1. Runtime thread-safety assertion in get_or_create(): The reviewer suggested adding `assert threading.current_thread() is threading.main_thread()`. We documented the constraint in the docstring (T01.03) but deferred the runtime check to a future release. Rationale: adding a hard assertion risks breaking test harnesses that run from non-main threads, and the docstring + test coverage provides sufficient protection for v0.03. 2. Moving replay_historical_events into the factory: The adversarial panel considered moving replay into RunnerFactory.create() to make the invariant structural. The 4-expert consensus chose the registry guard approach because it preserves recovery flexibility — the caller can catch the exception and retry or fall back without the factory being opinionated about lifecycle. See Appendix B in tasklist. 3. Snapshot environment parity: The CI snapshot failure cannot be reproduced locally. Rather than blindly regenerating snapshots in CI (which masks real regressions), we documented the environment delta and recommend a dedicated CI snapshot update workflow.

This is the only **user-visible misinformation** in the current implementation. The fix is XS (one string edit) with zero regression risk. + +**Action**: Remove "or scroll to top" from the banner text in `richlog_visualizer.py`. If FR-4b (scroll-to-top trigger) is confirmed as a requirement, schedule it as a separate follow-up with debounce/one-shot guards and dedicated tests. + +**Advocate highlights**: +- Only remediation that fixes a direct user-facing lie in the UI +- Fastest possible fix (one string change) +- Eliminates support confusion from "documented but non-functional" interaction + +**Critic concessions**: +- Core function (Page Up) works; this is UX copy, not a functional defect +- Could defer entirely if telemetry shows low scroll-to-top usage + +--- + +### Priority 2 (tie) — R1: Add forgotten_event_ids filtering test + +**Verdict**: ACCEPT + +**Rationale**: The filtering logic at `_build_condensation_plan()` lines 424-429 excludes events by ID from the forgotten set, but no test places a *post-condensation* event ID in `forgotten_event_ids` to verify exclusion. All existing tests only put pre-condensation event IDs in the forgotten set, which never reach the tail filter. This is the most significant untested behavioral contract. + +**Action**: Add a unit test where a tail-positioned event's ID appears in `forgotten_event_ids`, asserting it is excluded from `tail_events` and counts adjust correctly. Optionally mirror for the non-Sequence (iterator) path. + +**Advocate highlights**: +- A future refactor could drop the `event.id not in forgotten` check and all 104 tests would still pass +- High signal-to-effort ratio (one focused test) +- Core data-integrity contract currently untested + +**Critic concessions**: +- In practice, forgotten IDs typically reference pre-condensation events, so the untested path may rarely execute +- Existing tests heavily exercise the condensation pathway through other dimensions + +--- + +### Priority 2 (tie) — R6: Test cross-boundary widget content directly + +**Verdict**: ACCEPT + +**Rationale**: `_create_cross_boundary_observation_widget()` explicitly formats `"(action not shown) {title}"` but the existing test patches the method itself and only asserts it was called — never inspecting the output widget. The "(action not shown)" indicator is user-visible text that could silently break. + +**Action**: Add a test that calls the real `_create_cross_boundary_observation_widget()` (or spies on `_make_collapsible` arguments) and asserts the title contains `"(action not shown)"`. + +**Advocate highlights**: +- XS effort for a user-visible semantic contract +- Current test is tautological for content — only tests routing +- Private helper has explicit formatting logic that should be locked + +**Critic concessions**: +- Testing private methods can couple tests to implementation details +- If wording is intentionally flexible, exact-string assertions create noise + +--- + +### Priority 3 — R3: Add logger.warning on config fallback + +**Verdict**: ACCEPT + +**Rationale**: `CliSettings.load()` catches `(json.JSONDecodeError, ValueError)` and silently returns defaults. AC-11 explicitly requires "warning logged." Users with corrupted config files get no diagnostic signal. + +**Action**: Add `logger.warning("Failed to load CLI settings from %s: %s; using defaults", path, exc)` in the except block. Keep the `return cls()` fallback unchanged. + +**Advocate highlights**: +- Direct spec non-compliance (AC-11) +- Silent config fallback hides corruption — operators can't detect it +- XS effort, zero behavioral change + +**Critic concessions**: +- If `load()` is called frequently, the warning could be noisy +- Downstream code handles defaults smoothly regardless + +--- + +### Priority 4 — R5: Add _flush_live_event_buffer end-to-end test + +**Verdict**: MODIFY (tighten scope) + +**Rationale**: The flush path is invoked in a critical `finally` block after prepend. If it regresses, live events buffered during prepend are silently dropped. Only the append side is currently tested. + +**Action**: Add one focused test: simulate prepend mode → buffer a live event → exit prepend → call `_flush_live_event_buffer()` → assert buffer is empty AND the event was re-dispatched via `on_event()`. Keep assertions on buffer state and call count, not widget internals. + +**Advocate highlights**: +- Drain path is in a `finally` block — if broken, events are silently lost +- Re-enters `on_event()` which has side-effect branches +- Buffer append without drain verification is half a test + +**Critic concessions**: +- Flush is a simple 3-line loop (`popleft` + `on_event`); defect likelihood is low +- Broader E2E assertions risk brittleness + +--- + +### Priority 5 — R2: Fix LOG-1 to include event count + +**Verdict**: ACCEPT (lowest urgency) + +**Rationale**: LOG-1 logs `_replayed_event_offset` (always 0 at entry) rather than event count. The event count is already captured in LOG-2. This is a spec-compliance and debuggability improvement, not a functional gap. + +**Action**: Move `events = self.conversation.state.events` and `total_count = len(events)` above LOG-1, or add a second log line after the early-return guard. Include `total_count` and `window_size` in the entry log. + +**Advocate highlights**: +- Spec requires event count in entry log +- Helps correlate early-return behavior (offset > 0 path) +- XS effort, zero risk + +**Critic concessions**: +- LOG-2 already captures total count — information is not lost, just delayed +- Moving computation before the early-return guard adds work on the no-op path + +--- + +## Rejected / Deferred Items + +None rejected.

All agents agreed the text fix (Option B) is the right immediate action, with Option A (wiring `on_scroll`) deferred as a separate feature. + +2. **R1 and R6 share the same structural weakness** — tests that verify routing/delegation but not the actual transformation. Both were promoted to P2 as "tests that could pass with broken implementations." + +3. **R5's critic made the strongest concession** — the flush loop is trivially simple (`popleft` + `on_event`), but the advocate correctly noted that silent event loss in a `finally` block is high-consequence even if low-probability. + +4. **R2 was demoted from original P2 to P5** — all agents agreed the information exists in LOG-2 and the fix is purely spec-compliance hygiene, not a functional gap. + +5. **No items were rejected** — all 6 represent genuine gaps confirmed by evidence.

Replay guard bypass (conversation_runner.py): - Guard `_replayed_event_offset > 0` fails when tail is empty (e.g., condensation is the last event — offset stays 0) - Added `_replay_complete` boolean flag as the idempotence guard - Preserves _replayed_event_offset contract as event delivery count 2. PageUp index stall (richlog_visualizer.py): - `_loaded_start_index -= mounted` under-decrements when _create_replay_widget returns None for filtered events - Changed to `consumed` counter tracking all events processed, not just those producing widgets - Cap-break correctly limits consumed (unlike len(older_events)) Tests: 3 regression tests added (633/633 TUI suite passing) --- Changed files (our work only): ┌─────────────────────────────────────────────────────┬───────┐ │ File │ Delta │ ├─────────────────────────────────────────────────────┼───────┤ │ openhands_cli/tui/core/conversation_runner.py │ +9/-2 │ ├─────────────────────────────────────────────────────┼───────┤ │ openhands_cli/tui/widgets/richlog_visualizer.py │ +4/-2 │ ├─────────────────────────────────────────────────────┼───────┤ │ tests/tui/core/test_conversation_runner_replay.py │ +79 │ ├─────────────────────────────────────────────────────┼───────┤ │ tests/tui/widgets/test_richlog_visualizer_replay.py │ +88 │ └─────────────────────────────────────────────────────┴───────┘ --- docs/ARCHITECTURE.md | 725 ------------------ docs/PROJECT_INDEX.json | 131 ---- docs/PROJECT_INDEX.md | 208 ----- .../v0.04-remediation-debate-results.md | 169 ---- docs/generated/v0.04-sprint-papertrail.md | 345 --------- openhands_cli/tui/core/conversation_runner.py | 9 +- .../tui/widgets/richlog_visualizer.py | 4 +- .../core/test_conversation_runner_replay.py | 79 ++ .../widgets/test_richlog_visualizer_replay.py | 88 +++ 9 files changed, 177 insertions(+), 1581 deletions(-) delete mode 100644 docs/ARCHITECTURE.md delete mode 100644 docs/PROJECT_INDEX.json delete mode 100644 docs/PROJECT_INDEX.md delete mode 100644 docs/generated/v0.04-remediation-debate-results.md delete mode 100644 docs/generated/v0.04-sprint-papertrail.md diff --git a/docs/ARCHITECTURE.md b/docs/ARCHITECTURE.md deleted file mode 100644 index 64086724d..000000000 --- a/docs/ARCHITECTURE.md +++ /dev/null @@ -1,725 +0,0 @@ -# OpenHands CLI — Deep Architecture Reference - -> Generated: 2026-03-02 | For AI agents working on this codebase. -> Covers the 5 critical knowledge gaps not documented elsewhere. - ---- - -## Table of Contents - -1.

Also handles `SystemPromptEvent`, `PauseEvent`, `Condensation`, `CondensationRequest` (via `SharedEventHandler`), plus `UserRejectObservation` and `AgentErrorEvent` (→ tool call failed status). -- Skips `ConversationStateUpdateEvent` (internal state, not forwarded to client). - -**Path B: Streaming (`TokenBasedEventSubscriber` in `events/token_streamer.py`)** -- Used when `streaming_enabled=True` AND `not agent.llm.uses_responses_api()`. -- Two entry points from separate source threads: - 1. **Token-level**: `on_token(chunk)` from LLM streaming → `_schedule_update()` → `run_coroutine_threadsafe` → real-time `AgentMessageChunk` updates. - 2. **Event-level**: `sync_callback(event)` from SDK callback thread → `token_subscriber.unstreamed_event_handler(event)` — handles completed events after streaming finishes and resets header state for next response. -- Uses `ToolCallState` (`events/tool_state.py`) per streaming tool call to track incremental arg parsing with `has_valid_skeleton` gate (prevents flickering). - -**`SharedEventHandler` (`events/shared_event_handler.py`)** -- Shared logic used by both subscriber types via the `_ACPContext` protocol. -- Handles: `ThinkAction` → thought text, `FinishAction` → agent message, other actions → `start_tool_call(...)`, observations (except Think/Finish observations) → `send_tool_progress(...)`, `TaskTrackerObservation` → `AgentPlanUpdate`. - -### 1.5 Thread Bridging Pattern - -The SDK's `conversation.run()` is synchronous and executes in a worker thread. ACP event delivery is async. The bridge: - -```python -# local_agent.py:159-172 -loop = asyncio.get_event_loop() # Capture the async event loop - -def sync_callback(event: Event) -> None: # Called from SDK worker thread - if streaming_enabled: - asyncio.run_coroutine_threadsafe( - token_subscriber.unstreamed_event_handler(event), loop) - else: - asyncio.run_coroutine_threadsafe(subscriber(event), loop) -``` - -Additionally, `TokenBasedEventSubscriber._schedule_update()` bridges from the LLM streaming thread: -```python -# token_streamer.py:226-239 -def _schedule_update(self, update): - async def _send(): - await self.conn.session_update(session_id=..., update=update, ...) - if self.loop.is_running(): - asyncio.run_coroutine_threadsafe(_send(), self.loop) - else: - self.loop.run_until_complete(_send()) # defensive fallback -``` - -**All bridge sites:** - -| Location | Sync Source | Async Target | -|---|---|---| -| `local_agent.py:168-172` | SDK callback thread | `subscriber(event)` or `token_subscriber.unstreamed_event_handler(event)` | -| `remote_agent.py:235` | SDK callback thread | `subscriber(event)` | -| `token_streamer.py:237` | LLM stream thread | `conn.session_update(...)` | - ---- - -## 2.

Both default to `~/.openhands`. -- Additional env vars affect derived paths: `OPENHANDS_CONVERSATIONS_DIR` overrides the conversations directory (default: `{persistence_dir}/conversations`), and `OPENHANDS_WORK_DIR` overrides the working directory used for skill loading (default: `cwd`). -- `mcp.json` has no dedicated env override — it inherits `OPENHANDS_PERSISTENCE_DIR`. - -### 2.2 What Is Persisted vs. Derived at Runtime - -| Field | Persisted? | Source | -|---|---|---| -| `agent.llm` (model, api_key, base_url, timeout) | **Yes** — `agent_settings.json` | User setup or settings screen | -| `agent.condenser` | **Yes** — `agent_settings.json` | Created alongside LLM | -| `agent.tools` | **No** — derived | `base_state.json` (resume) or `get_default_cli_tools()` (new) | -| `agent.mcp_config` | **No** — derived | `~/.openhands/mcp.json` via `list_enabled_servers()` | -| `agent.agent_context` | **No** — derived | `load_project_skills(get_work_dir())` + OS description | -| `agent.critic` | **No** — derived | Auto-derived from `llm.base_url` pattern match | -| `agent.llm.litellm_extra_body` | **No** — derived | Added if using OpenHands proxy | -| Hooks (`HookConfig`) | **No** — read each time | `hooks.json` loaded in `setup_conversation()` | - -### 2.3 Why Tools Are in `base_state.json`, Not `agent_settings.json` - -Tools must match the conversation they were created with. From the code: - -> "When resuming a conversation, we should use the tools that were available when the conversation was created, not the current default tools. This ensures consistency and prevents issues with tools that weren't available in the original conversation (e.g., delegate tool)." - -The mechanism: -1. At conversation creation, the SDK writes `base_state.json` with the tool list. -2. On resume, `AgentStore._resolve_tools(session_id)` calls `get_persisted_conversation_tools(conversation_id)` which reads that file. -3. For new conversations, `get_default_cli_tools()` provides: `TerminalTool`, `FileEditorTool`, `TaskTrackerTool`, `DelegateTool`. - -### 2.4 Complete Load Chain - -``` -entrypoint.py: main() - └─ textual_app.main() - └─ OpenHandsApp.__init__() - ├─ CliSettings.load() # reads cli_config.json - │ └─ _migrate_legacy_settings() # auto-saves if migrated - ├─ ConversationContainer( - │ initial_confirmation_policy=..., - │ initial_critic_settings=cli_settings.critic) - ├─ RunnerFactory(env_overrides_enabled, critic_disabled, ...) - └─ ConversationManager(state, runner_factory, store_service, ...) - └─ RunnerRegistry(factory=runner_factory, ...) - - [User sends first message OR resume ID provided] - - RunnerRegistry.get_or_create(conversation_id) - └─ RunnerFactory.create(conversation_id, ...) - └─ ConversationRunner.__init__() - └─ setup_conversation(conversation_id, ...) # module fn in setup.py - ├─ load_agent_specs(session_id, ...) - │ └─ AgentStore().load_or_create(session_id, ...) - │ │ - │ ├─ load_from_disk() → Agent from agent_settings.json - │ ├─ [if --override-with-envs] → apply LLM_API_KEY/MODEL/BASE_URL - │ └─ _apply_runtime_config(): - │ ├─ _resolve_tools() → base_state.json or defaults - │ ├─ _with_llm_metadata() → litellm_extra_body if proxy - │ ├─ _build_agent_context()→ skills + OS info - │ ├─ list_enabled_servers()→ mcp.json - │ ├─ _maybe_build_condenser() → re-tag condenser LLM metadata - │ └─ CliSettings.load() → get_default_critic() - │ → regex match → APIBasedCritic or None - ├─ HookConfig.load(get_work_dir()) → hooks.json - └─ Conversation(agent, workspace, persistence_dir, hook_config, ...) - └─ runner.replay_historical_events() # no-op for new; replays on resume/switch -``` - -### 2.5 Env Overrides - -When `--override-with-envs` is passed: -- `LLM_API_KEY`, `LLM_BASE_URL`, `LLM_MODEL` are read from environment. -- If persisted agent exists: partial override allowed (e.g., only API key). -- If no persisted agent: both `LLM_API_KEY` and `LLM_MODEL` required (raises `MissingEnvironmentVariablesError`). -- Overrides are **never persisted** to disk. - -### 2.6 Migration Path for New Settings Fields - -**`CliSettings` / `CriticSettings`**: Add field with default value.

All SDK blocking calls are offloaded: - -**`run_in_executor` (asyncio thread-pool) — two sites:** -```python -# tui/core/conversation_runner.py:125-127 (process_message_async) -await asyncio.get_event_loop().run_in_executor( - None, self._run_conversation_sync, message, headless -) - -# tui/core/conversation_runner.py:203-204 (resume_after_confirmation) -await asyncio.get_event_loop().run_in_executor( - None, self._execute_conversation, decision -) -``` - -**`asyncio.to_thread` (for pause/condense):** -```python -# tui/core/conversation_runner.py:220, 245 -await asyncio.to_thread(self.conversation.pause) -await asyncio.to_thread(self.conversation.condense) -``` - -**Textual `run_worker` has two modes:** -- Async worker (default) for coroutine jobs like `process_message_async` and `resume_after_confirmation`. -- Thread worker (`thread=True`) for conversation switching: -```python -# tui/core/conversation_switch_controller.py:83-90 -self._run_worker( - worker, - name="switch_conversation", - group="switch_conversation", - exclusive=True, - thread=True, - exit_on_error=False, -) -``` - -### 5.2 The `_schedule_update` Gate - -`ConversationContainer._schedule_update()` (`tui/core/state.py:317-333`) is the central thread-safety mechanism for reactive state: - -```python -def _schedule_update(self, attr: str, value: Any) -> None: - def do_update(): - setattr(self, attr, value) - if threading.current_thread() is threading.main_thread(): - do_update() # Direct mutation - else: - self.app.call_from_thread(do_update) # Schedule on main thread -``` - -**Every public setter** (`set_running`, `set_metrics`, `set_conversation_id`, etc.) routes through this gate. Direct `setattr` on reactive vars from a worker thread (bypassing `set_*` methods) is a bug. - -Note: `reset_conversation_state()` uses direct assignment but is safe because it is always invoked on the main thread (switch path via `call_from_thread`; new-conversation path via Textual message handler). - -`ConversationVisualizer` also has a parallel UI-thread helper (`_run_on_main_thread`) for widget-mounting work initiated by event callbacks. - -### 5.3 ACP Threading - -Pure asyncio — no Textual, no `_schedule_update`. The key pattern: - -```python -# acp_impl/runner.py:54 -await asyncio.to_thread(conversation.run) # SDK blocking call in thread -``` - -Events from the SDK thread use `asyncio.run_coroutine_threadsafe` to bridge back (see [Section 1.5](#15-thread-bridging-pattern)). - -ACP task lifecycle is tracked per session (`_running_tasks`); cancellation pauses the conversation, awaits task completion with timeout, then falls back to `task.cancel()` when needed. - -### 5.4 Comparison - -| Aspect | TUI | ACP | -|---|---|---| -| SDK `run()` | `run_in_executor` (via async workers) / thread worker for switch | `asyncio.to_thread` | -| Thread-safe UI updates | `_schedule_update` → `call_from_thread`; plus visualizer `_run_on_main_thread` | N/A (no UI) | -| Event delivery from worker | `post_message` (thread-safe) and `call_from_thread(post_message)` | `run_coroutine_threadsafe` | -| Cancellation | `conversation.pause()` via `to_thread` or switch worker | `conversation.pause()` + await task (then `Task.cancel()` on timeout) | - -### 5.5 Thread Safety Rules - -| Operation | Safe From | Mechanism | -|---|---|---| -| Update `ConversationContainer` reactive vars | Any thread | `_schedule_update` auto-detects | -| Mount Textual widgets from callbacks | Any thread | Visualizer `_run_on_main_thread` / `call_from_thread` | -| Post Textual messages | Any thread | Textual thread-safe `post_message` | -| SDK `conversation.run()` | Worker thread only | Never call from main thread | -| SDK `conversation.pause()` | Any thread | Thread-safe in SDK | -| Read reactive vars | Any thread (read-only) | No synchronization needed | -| ACP `conn.session_update()` | Main event loop only | Via `run_coroutine_threadsafe` | - ---- - -## 6.

One ACP update per SDK event. - -**Streaming:** Two parallel paths: -1. `on_token(chunk)` → `_schedule_update()` → real-time token delivery (content/reasoning text + incremental tool call args). -2. `sync_callback(event)` → `token_subscriber.unstreamed_event_handler(event)` → updates tool call summaries, handles observations. - -Streaming produces many small updates (per-token); non-streaming produces fewer, larger updates (per-event). - -Note: ACP `prompt()` creates the run task with `asyncio.create_task(...)` but immediately `await`s it; `PromptResponse(stop_reason="end_turn")` returns only after run completion/pause. - ---- - -## 7.

---- - -## Revised Priority Order - -### Priority 1 — R4: Update banner text to match implemented behavior - -**Verdict**: MODIFY (Option B — text fix now; Option A deferred) - -**Rationale**: The banner says "Press [Page Up] or scroll to top to load more" but only Page Up is wired. This is the only **user-visible misinformation** in the current implementation. The fix is XS (one string edit) with zero regression risk. - -**Action**: Remove "or scroll to top" from the banner text in `richlog_visualizer.py`. If FR-4b (scroll-to-top trigger) is confirmed as a requirement, schedule it as a separate follow-up with debounce/one-shot guards and dedicated tests. - -**Advocate highlights**: -- Only remediation that fixes a direct user-facing lie in the UI -- Fastest possible fix (one string change) -- Eliminates support confusion from "documented but non-functional" interaction - -**Critic concessions**: -- Core function (Page Up) works; this is UX copy, not a functional defect -- Could defer entirely if telemetry shows low scroll-to-top usage - ---- - -### Priority 2 (tie) — R1: Add forgotten_event_ids filtering test - -**Verdict**: ACCEPT - -**Rationale**: The filtering logic at `_build_condensation_plan()` lines 424-429 excludes events by ID from the forgotten set, but no test places a *post-condensation* event ID in `forgotten_event_ids` to verify exclusion. All existing tests only put pre-condensation event IDs in the forgotten set, which never reach the tail filter. This is the most significant untested behavioral contract. - -**Action**: Add a unit test where a tail-positioned event's ID appears in `forgotten_event_ids`, asserting it is excluded from `tail_events` and counts adjust correctly. Optionally mirror for the non-Sequence (iterator) path. - -**Advocate highlights**: -- A future refactor could drop the `event.id not in forgotten` check and all 104 tests would still pass -- High signal-to-effort ratio (one focused test) -- Core data-integrity contract currently untested - -**Critic concessions**: -- In practice, forgotten IDs typically reference pre-condensation events, so the untested path may rarely execute -- Existing tests heavily exercise the condensation pathway through other dimensions - ---- - -### Priority 2 (tie) — R6: Test cross-boundary widget content directly - -**Verdict**: ACCEPT - -**Rationale**: `_create_cross_boundary_observation_widget()` explicitly formats `"(action not shown) {title}"` but the existing test patches the method itself and only asserts it was called — never inspecting the output widget. The "(action not shown)" indicator is user-visible text that could silently break. - -**Action**: Add a test that calls the real `_create_cross_boundary_observation_widget()` (or spies on `_make_collapsible` arguments) and asserts the title contains `"(action not shown)"`. - -**Advocate highlights**: -- XS effort for a user-visible semantic contract -- Current test is tautological for content — only tests routing -- Private helper has explicit formatting logic that should be locked - -**Critic concessions**: -- Testing private methods can couple tests to implementation details -- If wording is intentionally flexible, exact-string assertions create noise - ---- - -### Priority 3 — R3: Add logger.warning on config fallback - -**Verdict**: ACCEPT - -**Rationale**: `CliSettings.load()` catches `(json.JSONDecodeError, ValueError)` and silently returns defaults. AC-11 explicitly requires "warning logged." Users with corrupted config files get no diagnostic signal. - -**Action**: Add `logger.warning("Failed to load CLI settings from %s: %s; using defaults", path, exc)` in the except block. Keep the `return cls()` fallback unchanged. - -**Advocate highlights**: -- Direct spec non-compliance (AC-11) -- Silent config fallback hides corruption — operators can't detect it -- XS effort, zero behavioral change - -**Critic concessions**: -- If `load()` is called frequently, the warning could be noisy -- Downstream code handles defaults smoothly regardless - ---- - -### Priority 4 — R5: Add _flush_live_event_buffer end-to-end test - -**Verdict**: MODIFY (tighten scope) - -**Rationale**: The flush path is invoked in a critical `finally` block after prepend. If it regresses, live events buffered during prepend are silently dropped. Only the append side is currently tested. - -**Action**: Add one focused test: simulate prepend mode → buffer a live event → exit prepend → call `_flush_live_event_buffer()` → assert buffer is empty AND the event was re-dispatched via `on_event()`. Keep assertions on buffer state and call count, not widget internals. - -**Advocate highlights**: -- Drain path is in a `finally` block — if broken, events are silently lost -- Re-enters `on_event()` which has side-effect branches -- Buffer append without drain verification is half a test - -**Critic concessions**: -- Flush is a simple 3-line loop (`popleft` + `on_event`); defect likelihood is low -- Broader E2E assertions risk brittleness - ---- - -### Priority 5 — R2: Fix LOG-1 to include event count - -**Verdict**: ACCEPT (lowest urgency) - -**Rationale**: LOG-1 logs `_replayed_event_offset` (always 0 at entry) rather than event count. The event count is already captured in LOG-2. This is a spec-compliance and debuggability improvement, not a functional gap. - -**Action**: Move `events = self.conversation.state.events` and `total_count = len(events)` above LOG-1, or add a second log line after the early-return guard. Include `total_count` and `window_size` in the entry log. - -**Advocate highlights**: -- Spec requires event count in entry log -- Helps correlate early-return behavior (offset > 0 path) -- XS effort, zero risk - -**Critic concessions**: -- LOG-2 already captures total count — information is not lost, just delayed -- Moving computation before the early-return guard adds work on the no-op path - ---- - -## Rejected / Deferred Items - -None rejected.

All agents agreed the text fix (Option B) is the right immediate action, with Option A (wiring `on_scroll`) deferred as a separate feature. - -2. **R1 and R6 share the same structural weakness** — tests that verify routing/delegation but not the actual transformation. Both were promoted to P2 as "tests that could pass with broken implementations." - -3. **R5's critic made the strongest concession** — the flush loop is trivially simple (`popleft` + `on_event`), but the advocate correctly noted that silent event loss in a `finally` block is high-consequence even if low-probability. - -4. **R2 was demoted from original P2 to P5** — all agents agreed the information exists in LOG-2 and the fix is purely spec-compliance hygiene, not a functional gap. - -5. **No items were rejected** — all 6 represent genuine gaps confirmed by evidence. The debate refined priorities and scoping rather than eliminating items. diff --git a/docs/generated/v0.04-sprint-papertrail.md b/docs/generated/v0.04-sprint-papertrail.md deleted file mode 100644 index f28e800d4..000000000 --- a/docs/generated/v0.04-sprint-papertrail.md +++ /dev/null @@ -1,345 +0,0 @@ -# v0.04 Adaptive Replay — Sprint Papertrail (In-Progress) -

-Result: **104 passed**. - ---- - -## 5) Key Decisions & Rationale - -1. **Use strict replay cascade** with deterministic fallback. - - Rationale: avoid O(n) startup replay and ensure no hard failure if condensation path has issues. - -2. **Adopt summary banner variants** for condensation/no-condensation paths. - - Rationale: maintain explicit UX state and user affordance for loading older context. - -3. **Add on-demand loading through PageUp + message routing**. - - Rationale: avoids aggressive upfront rendering while retaining user control. - -4. **Buffer live events during prepend**. - - Rationale: prevents race/interleaving corruption during historical insertion. - -5. **Enforce 2000 viewable-widget cap**. - - Rationale: bound UI rendering cost and memory footprint. - ---- - -## 6) Known Limitations / Follow-ups - -- Scroll restoration during prepend currently uses an approximation (`before_scroll + mounted`). - - Spike indicates viability; production behavior should still be validated with mixed-height real widgets in extended E2E/snapshot coverage. - -- This papertrail captures **work through Phase 6** (all phases complete). - -- `.serena/` appears untracked in working tree (not part of implementation changes). - ---- - -## Phase 5 - -### T05.01 — Add 5-point replay DEBUG logging -- Implemented in `openhands_cli/tui/core/conversation_runner.py` - - LOG-1: Entry (offset check) - - LOG-2: Path selected (condensation/window/full + metrics) - - LOG-3: Exit (widget count + duration in ms) - - LOG-4: Condensation path detail (summary presence, forgotten count) - - LOG-5: Fallback triggered (warning on condensation failure) -- Added `import time` for monotonic duration measurement. - -### T05.02 — Enforce window-scoped action/observation pairing -- Implemented in `openhands_cli/tui/widgets/richlog_visualizer.py` - - `_create_cross_boundary_observation_widget()`: renders "(action not shown)" prefix - - `_render_event_for_replay()`: routes unpaired observations to cross-boundary handler - -### T05.03 — Update existing replay tests for new APIs -- All 28 existing replay tests pass without modification after Phase 5 changes. -- No test updates required; backward-compatible additions only. - -### T05.04 — Add CI grep guard for `list(state.events)` -- New file: `tests/tui/core/test_nfr5_guard.py` - - Parametrized test over 3 guarded files - - Pattern: `list(state.events)` / `list(self.conversation.state.events)` - - Passes on current codebase (zero violations) - -### T05.05 — Add edge-case boundary tests -- Added `TestReplayEdgeCaseBoundaries` class in `test_conversation_runner_replay.py`: - - `test_window_size_one_returns_single_event` - - `test_window_larger_than_event_count_replays_all` - - `test_zero_events_returns_zero` - - `test_exact_window_size_replays_all` - - `test_single_event_with_default_window` -- Added `test_cross_boundary_observation_gets_indicator` in `test_richlog_visualizer_replay.py` - -## Phase 6 - -### T06.01 — End-to-end LoadOlderEvents integration test -- New file: `tests/tui/core/test_integration_load_older.py` - - `test_full_chain_loads_older_events`: runner→visualizer full chain - - `test_manager_delegates_to_runner_which_loads`: manager→runner delegation - - `test_cap_prevents_unbounded_loading`: widget cap enforcement - - `test_load_returns_zero_when_all_loaded`: boundary condition - -### T06.02 — 1K/10K/60K automated smoke tests -- New file: `tests/tui/core/test_replay_scale_performance.py` - - `TestReplayScaleSmoke`: parametrized at 1K/10K/60K - - Bounded widget count assertion (== window_size) -
