beabigegg 69b81d9241 feat: implement kanban real-time sync and fix workload cache
## Kanban Real-time Sync (NEW-002)
- Backend:
  - WebSocket endpoint: /ws/projects/{project_id}
  - Project room management in ConnectionManager
  - Redis Pub/Sub: project:{project_id}:tasks channel
  - Task CRUD event publishing (5 event types)
  - Redis connection retry with exponential backoff
  - Race condition fix in broadcast_to_project

- Frontend:
  - ProjectSyncContext for WebSocket management
  - Reconnection with exponential backoff (max 5 attempts)
  - Multi-tab event deduplication via event_id
  - Live/Offline connection indicator
  - Optimistic updates with rollback

- Spec:
  - collaboration spec: +1 requirement (Project Real-time Sync)
  - 7 new scenarios for real-time sync

## Workload Cache Fix (NEW-001)
- Added cache invalidation to all task endpoints:
  - create_task, update_task, update_task_status
  - delete_task, restore_task, assign_task
- Extended to clear heatmap cache as well

FastAPI 後端服務

系統需求

必要服務

服務 版本 說明
Python 3.11+ 執行環境
MySQL 8.0+ 主要資料庫
Redis 6.0+ Session 存儲

Redis Server 安裝

Redis Python 套件 (redis==5.0.1) 僅為客戶端,需另外安裝 Redis Server

macOS (Homebrew):

brew install redis
brew services start redis

Ubuntu/Debian:

sudo apt update
sudo apt install redis-server
sudo systemctl start redis-server
sudo systemctl enable redis-server

Docker:

docker run -d --name redis -p 6379:6379 redis:alpine

驗證安裝:

redis-cli ping
# 應回傳 PONG

環境建置

# 使用 Conda
conda env create -f environment.yml
conda activate pjctrl

# 或使用 pip
pip install -r requirements.txt

設定

複製並編輯環境變數:

cp .env.example .env

主要設定項目:

  • MYSQL_* - 資料庫連線
  • REDIS_* - Redis 連線
  • JWT_SECRET_KEY - JWT 簽名密鑰 (生產環境必須更換)
  • AUTH_API_URL - 外部認證 API

執行

# 開發模式
uvicorn app.main:app --reload --port 8000

# 生產模式
uvicorn app.main:app --host 0.0.0.0 --port 8000

資料庫遷移

# 升級至最新版本
alembic upgrade head

# 回滾一個版本
alembic downgrade -1

測試

pytest -v
