* chore: add pytest-asyncio in auto mode
* test: migrate channel and stream tests to native async
Convert run_async() wrapper tests to plain 'async def test_*' under
pytest-asyncio auto mode. collect_events() in stream_v3_fakes becomes a
coroutine awaited at every call site.
* test: migrate command and model/middleware tests to native async
Convert run_async() wrappers (import, alias, and fixture forms) to plain
'async def test_*'. Multi-call tests merge onto one loop as sequential
awaits; none asserted on loop identity.
* test: migrate TUI, notifier, gateway, and session tests to native async
TUI/notifier/gateway files convert run_async wrappers to plain async
tests. test_sessions.py's unittest.TestCase classes move to
unittest.IsolatedAsyncioTestCase (pytest-asyncio does not await async
methods on plain TestCase; converting blindly would have made ~70 tests
silently vacuous). Its setUpClass keeps a one-shot asyncio.run() since
IsolatedAsyncioTestCase has no async class-level hook. TestLoadingWidget
in test_tui_widgets.py drops its TestCase base for the same reason.
* test: replace direct asyncio.run() calls with native async tests
Convert tests that called asyncio.run() (directly or via a local _run
helper) to plain 'async def test_*'; delete the local helpers.
* test: drop undeclared anyio markers and delete run_async helper
The @pytest.mark.anyio tests relied on anyio being a transitive dep of
httpx; auto-mode pytest-asyncio collects them natively. run_async() and
its fixture are unreferenced after the migration, so remove them —
pytest-asyncio's per-test loop teardown covers the pending-task
cancellation the helper existed for (verified: full suite runs with no
'Event loop is closed' errors or destroyed-task warnings).
* feat: Implement async sub-agent auto-notification system
- Added async notifier functionality to handle notifications for sub-agents reaching terminal states.
- Introduced `AsyncTaskNotification` dataclass for structured notification data.
- Implemented `watch_run_and_notify` to monitor agent runs and enqueue notifications.
- Created `spawn_watcher` to manage watcher tasks and ensure proper cancellation of previous watchers.
- Developed `consume_notifications` to process notifications, deduplicate them, and format messages for LLM.
- Added tests for notification handling, including draining, deduplication, and formatting.
- Patched deepagents to integrate the new watcher functionality into start and update tools.
* Enhance async notifier with per-thread notification routing and error handling
- Introduced `origin_cli_thread_id` to `AsyncTaskNotification` for routing notifications back to the originating CLI session.
- Implemented per-thread notification queues to handle notifications based on the originating thread.
- Updated `has_pending_notifications` and `drain_notifications` to respect thread-specific queues.
- Enhanced `watch_run_and_notify` to detect in-band error events from the SSE stream and handle clean exits.
- Modified tests to verify the new notification routing behavior and ensure proper handling of notifications across threads.
- Added a fixture to restore the async watcher patch state in tests to prevent state leakage.
- Updated deepagents patching to capture the main agent's CLI thread ID for notification routing.
* feat: Enhance async notifier with thread-specific watcher management and notification filtering
* test: Enhance notification draining logic for cleaner test setup
* refactor: Remove summary field from AsyncTaskNotification and update related tests
* feat: Enhance async notification handling with target thread ID support
* Refactor async notifier and middleware for improved task management
- Removed the no-op shutdown watcher loop from async_notifier.py as it is no longer needed.
- Updated watch_run_and_notify to clarify notification handling and race conditions.
- Cleaned up shutdown handling in commands.py, interactive.py, and tui_interactive.py by removing obsolete shutdown watcher calls.
- Deleted the deepagents async watcher patch from patches.py, transitioning to a new middleware approach.
- Introduced AsyncWatcherMiddleware to handle async task notifications directly during tool calls.
- Updated tests to validate the new middleware functionality and ensure proper watcher spawning and cancellation.
- Enhanced test coverage for async watcher middleware, including edge cases and error handling.
* feat(tests): add fixture to reset notifier state before each test
