Add APScheduler BackgroundScheduler to on_startup that polls
takeover_service.poll_and_process_messages every 10 seconds. Added
redis and apscheduler dependencies. Added poll_and_process_messages,
fetch_unread_messages, and process_message methods to TakeoverService.
Scheduler initialization is graceful — Redis/Box IM failures do not
prevent app startup.
- Fix C1: check_takeover_enabled now uses owner_huihui_id to query Avatar first
- Fix C2: execute_takeover resolves owner_id via Avatar model (Authorization has no owner_id)
- Fix I1: add test for None case (no Avatar found)
- Fix I2: add test verifying filter arguments
- Fix I3: implement process_delayed_queue to scan and dispatch expired messages
Implement TakeoverService for avatar takeover chat feature:
- check_takeover_enabled: query Authorization for enabled takeover
- generate_reply: call local chat API via httpx to generate responses
- execute_takeover: get owner IM credentials, generate reply, send via BoxIM
- enqueue_delayed_message: Redis delayed queue with graceful degradation
- process_delayed_queue: placeholder for scheduled worker
Service degrades gracefully when Redis is unavailable.
Prevents stale signature values from leaking into the MD5 signing
calculation, matching the news_service.py pattern. Adds a test that
passes a stale signature in extra params and verifies the returned
signature is freshly computed.
Add BoxIMClient with get_credentials and send_p2p_message methods,
using Huihui platform MD5 signing mechanism (sorted keys, 24h timestamp,
12-char alphanumeric nonce). Includes full test coverage.
Add takeover_enabled, takeover_mode, and takeover_delay_seconds columns
to the Authorization model with a SQLite migration, and include them
in to_dict(). Test: test_takeover_model.py.
- Add POST /api/avatar/{id}/photo endpoint
- Save uploaded photos to UPLOAD_DIR/{avatar_id}/
- Update avatar.photo_url in database
- Import UPLOAD_DIR from knowledge router
