+# 🎯 三个"补丁"更新日志
+
+## 更新时间
+2026-04-05
+
+## 更新说明
+
+根据逍遥子的建议，为龙虾记忆同步系统添加了三个重要功能补丁，提升系统性能、可用性和安全性。
+
+---
+
+## 📦 补丁 1: 分块读取与流式传输
+
+### 问题
+- 如果龙虾的记忆文件（比如某些 Log 或向量快照）超过 50MB
+- 一次性 GET /api/diff 会让后端内存瞬间飙升
+
+### 解决方案
+- **流式读取**：使用 8KB 分块读取大文件，避免一次性加载到内存
+- **流式哈希计算**：直接从文件流计算哈希，无需加载完整内容
+- **差异对比限制**：大文件只显示头尾各 500 行，中间省略
+
+### 实现细节
+```python
+# services.py
+class FileScanner:
+    chunk_size = 8192  # 8KB 分块读取
+
+    def read_file_chunked(self, file_path: Path) -> str:
+        """分块读取文件"""
+        content_parts = []
+        with open(file_path, 'r', encoding='utf-8', errors='ignore') as f:
+            while True:
+                chunk = f.read(self.chunk_size)
+                if not chunk:
+                    break
+                content_parts.append(chunk)
+        return ''.join(content_parts)
+
+    def read_file_stream(self, file_path: str) -> Iterator[str]:
+        """流式读取文件（用于大文件传输）"""
+        with open(file_path, 'r', encoding='utf-8', errors='ignore') as f:
+            while True:
+                chunk = f.read(self.chunk_size)
+                if not chunk:
+                    break
+                yield chunk
+
+    def compute_hash_stream(self, file_path: Path) -> str:
+        """流式计算文件哈希（避免大文件内存问题）"""
+        hash_obj = hashlib.sha256()
+        with open(file_path, 'rb') as f:
+            while True:
+                chunk = f.read(self.chunk_size)
+                if not chunk:
+                    break
+                hash_obj.update(chunk)
+        return hash_obj.hexdigest()
+
+class DiffChecker:
+    def get_file_diff(self, local_content: str, db_content: str, max_lines: int = 1000) -> Dict:
+        """获取文件差异（支持大文件限制）"""
+        local_lines = local_content.split('\n')
+        db_lines = db_content.split('\n')
+
+        # 限制行数（大文件只显示头尾）
+        if len(local_lines) > max_lines:
+            local_head = local_lines[:max_lines//2]
+            local_tail = local_lines[-max_lines//2:]
+            local_lines = local_head + ['... (中间省略 {}) 行 ...'.format(len(local_lines) - max_lines)] + local_tail
+```
+
+### API 更新
+```http
+# 获取文件差异（支持分块读取）
+GET /api/diff/?lobster_id=daotong&file_path=large-file.log&chunked=true
+```
+
+---
+
+## 📦 补丁 2: .lobsterignore 机制
+
+### 问题
+- 临时文件（如 .DS_Store、日志缓存）不需要进数据库
+- 手动维护一个排除列表会更清爽
+
+### 解决方案
+- 创建 `.lobsterignore` 文件（类似 `.gitignore`）
+- 扫描时自动跳过匹配的文件
+- 提供默认忽略规则
+
+### 实现细节
+```python
+# services.py
+class IgnorePattern:
+    """.lobsterignore 模式匹配器"""
+
+    def __init__(self, base_dir: Path):
+        self.base_dir = base_dir
+        self.patterns = []
+        self.load_patterns()
+
+    def load_patterns(self):
+        """加载 .lobsterignore 文件"""
+        ignore_file = self.base_dir / '.lobsterignore'
+
+        if ignore_file.exists():
+            with open(ignore_file, 'r', encoding='utf-8') as f:
+                for line in f:
+                    line = line.strip()
+                    # 跳过空行和注释
+                    if line and not line.startswith('#'):
+                        self.patterns.append(line)
+
+        # 添加默认忽略规则
+        default_patterns = [
+            '.DS_Store', '.git', '.gitignore', '__pycache__',
+            'node_modules', '*.pyc', '*.pyo', '*.log',
+            '*.tmp', '*.temp', '*.bak', '.vscode', '.idea'
+        ]
+        for pattern in default_patterns:
+            if pattern not in self.patterns:
+                self.patterns.append(pattern)
+
+    def is_ignored(self, file_path: Path) -> bool:
+        """判断文件是否被忽略"""
+        relative_path = file_path.relative_to(self.base_dir)
+
+        for pattern in self.patterns:
+            # 匹配文件名
+            if fnmatch.fnmatch(file_path.name, pattern):
+                return True
+
+            # 匹配相对路径
+            if fnmatch.fnmatch(str(relative_path), pattern):
+                return True
+
+            # 匹配目录
+            if pattern.endswith('/') and fnmatch.fnmatch(str(relative_path.parent), pattern.rstrip('/')):
+                return True
+
+            # 递归匹配子目录
+            if pattern.startswith('*/'):
+                parts = str(relative_path).split(os.sep)
+                for i, part in enumerate(parts):
+                    if fnmatch.fnmatch(part, pattern[2:]):
+                        return True
+
+        return False

+
+## 📦 补丁 3: 操作溯源（Audit Log）
+
+### 问题
+- 万一哪天点错了，无法查到是哪次操作导致的
+- 需要记录操作历史，方便追溯问题
+
+### 解决方案
+- 新增 `SyncHistory` 模型
+- 记录每次同步操作的详细信息
+- 提供历史查询 API
+
+### 实现细节
+```python
+# models.py
+class SyncHistory(models.Model):
+    """同步操作历史记录"""

+    execution_time = models.FloatField(default=0, help_text='执行时间（秒）')
+    created_at = models.DateTimeField(auto_now_add=True, help_text='操作时间')
+
+# services.py
+class AuditLogger:
+    """操作日志记录器"""

+        status: str = 'success',
+        error_message: str = None,
+        execution_time: float = 0
+    ):
+        """记录同步操作"""

+        """获取操作历史"""
+        queryset = self.model.objects.all()
+        # 过滤和排序...
+```
+
+### 使用示例
+```python
+# views.py
+@api_view(['POST'])
+def sync_to_db(request):
+    """同步到数据库（带操作日志）"""
+    audit_logger = AuditLogger()

+        execution_time = time.time() - start_time
+
+        # 记录成功日志
+        audit_logger.log_sync_action(
+            lobster_id=lobster_id,
+            file_path=file_path,
+            action='sync_to_db',
+            old_version=old_version,
+            new_version=new_version,
+            old_hash=old_hash,

+        )
+
+    except Exception as e:
+        # 记录失败日志
+        audit_logger.log_sync_action(

+
+### API 更新
+```http
+# 获取操作历史
+GET /api/history/?lobster_id=daotong&file_path=MEMORY.md&limit=50
+```
+
+### 历史记录示例
+```json
+{
+  "success": true,
+  "data": [
+    {
+      "id": 1,
+      "lobster_id": "daotong",
+      "file_path": "MEMORY.md",
+      "action": "sync_to_db",
+      "action_display": "同步到数据库",
+      "status": "success",
+      "status_display": "成功",
+      "old_version": 1,
+      "new_version": 2,
+      "old_hash": "abc123...",

+      "created_at": "2026-04-05T12:00:00Z"
+    }
+  ]
+}
+```
+
+---
+
+## 📋 数据库迁移
+
+需要执行数据库迁移以创建 `SyncHistory` 表：
+
+```bash
+# 进入后端容器
+docker exec -it lobster-backend bash
+
+# 创建迁移
+python manage.py makemigrations memory_app
+python manage.py migrate
+```
+
+---
+
+## ✅ 完成检查清单
+
+- [x] 分块读取与流式传输（services.py）
+- [x] .lobsterignore 机制（services.py + .lobsterignore.example）
+- [x] 操作溯源（models.py + services.py + views.py + serializers.py）
+- [x] 新增 API 接口（urls.py）
+- [x] 更新文档（CHANGELOG.md）
+
+---
+
+## 🚀 下一步
+
+1. 执行数据库迁移
+2. 推送代码到远程仓库
+3. 更新前端界面（添加历史记录和忽略规则管理）

+### 环境准备
+
+#### 1. 安装 Docker
+
+**Ubuntu / Debian:**
+```bash
+# 更新包索引
+sudo apt-get update
+
+# 安装依赖
+sudo apt-get install -y ca-certificates curl gnupg lsb-release
+
+# 添加 Docker 官方 GPG key
+sudo mkdir -p /etc/apt/keyrings
+curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
+
+# 添加 Docker 仓库
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+
+# 安装 Docker
+sudo apt-get update
+sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
+
+# 验证安装
+docker --version
+docker compose version
+```
+
+**CentOS / RHEL:**
+```bash
+# 安装依赖
+sudo yum install -y yum-utils device-mapper-persistent-data lvm2
+
+# 添加 Docker 仓库
+sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
+
+# 安装 Docker
+sudo yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
+
+# 启动 Docker
+sudo systemctl start docker
+sudo systemctl enable docker
+```
+
+**macOS:**
+```bash
+# 使用 Homebrew 安装
+brew install --cask docker
+
+# 启动 Docker Desktop
+open -a Docker
+```
+
+#### 2. 配置 Docker 用户组（可选）
+
+```bash
+# 将当前用户添加到 docker 组
+sudo usermod -aG docker $USER
+
+# 重新登录或运行
+newgrp docker
+
+# 验证
+docker ps
+```
+
+### 安装部署
+
+#### 1. 克隆项目
+
+```bash
+# 克隆仓库
+git clone https://xjp.datalibstar.com/daotong/lobster-memory-sync.git
+cd lobster-memory-sync
+```
+
+#### 2. 配置环境变量
+
+创建 `.env` 文件（可选，用于覆盖默认配置）：
+
+```bash
+# 数据库配置
+DB_NAME=lobster_memory
+DB_USER=postgres
+DB_PASSWORD=your_secure_password
+
+# 龙虾记忆目录路径
+LOBSTER_MEMORY_BASE=/path/to/lobster/memory
+
+# 前端配置
+REACT_APP_API_URL=http://localhost:8087/api
+
+# 端口配置
+FRONTEND_PORT=8086
+BACKEND_PORT=8087
+POSTGRES_PORT=5432
+```
+
+#### 3. 修改 docker-compose.yml
+
+根据实际环境修改以下配置：
+
+```yaml
+services:
+  backend:
+    volumes:
+      # 挂载龙虾记忆目录（只读）
+      - /home/node/.openclaw/workspace/daotong:/app/memory_files:ro
+```
+
+**注意事项：**
+- 将 `/home/node/.openclaw/workspace/daotong` 替换为实际的龙虾记忆目录路径
+- 使用 `:ro` 只读挂载，确保安全性
+
+#### 4. 构建并启动服务
+
+```bash
+# 构建镜像
+docker-compose build
+
+# 启动所有服务（后台运行）
+docker-compose up -d
+
+# 查看服务状态
+docker-compose ps
+
+# 查看日志
+docker-compose logs -f
+```
+
+#### 5. 初始化数据库
+
+```bash
+# 等待数据库启动
+sleep 10
+
+# 执行数据库迁移
+docker-compose exec backend python manage.py migrate
+
+# 创建超级用户（可选）
+docker-compose exec backend python manage.py createsuperuser
+```
+
+### 验证部署
+
+#### 1. 检查服务状态
+
+```bash
+# 查看所有容器状态
+docker-compose ps
+
+# 预期输出：
+# NAME                    STATUS
+# lobster-postgres        Up
+# lobster-backend         Up
+# lobster-frontend        Up
+```
+
+#### 2. 测试后端 API
+
+```bash
+# 测试 API 健康检查
+curl http://localhost:8087/api/
+
+# 测试文件扫描
+curl "http://localhost:8087/api/scan/?lobster_id=daotong"
+```
+
+#### 3. 访问前端
+
+打开浏览器访问：
+- http://localhost:8086
+
+**预期效果：**
+- 能够看到文件树展示
+- 能够点击文件查看差异对比
+- 能够执行同步操作
+
+### 生产环境配置
+
+#### 1. 使用环境变量文件
+
+创建 `.env.production` 文件：
+
+```bash
+# 生产环境配置
+DB_NAME=lobster_memory_prod
+DB_USER=postgres
+DB_PASSWORD=<强密码>
+DB_HOST=postgres
+
+# 龙虾记忆目录
+LOBSTER_MEMORY_BASE=/var/lib/lobster/memory
+
+# 前端 API 地址
+REACT_APP_API_URL=https://api.yourdomain.com/api
+
+# 端口配置
+FRONTEND_PORT=8086
+BACKEND_PORT=8087
+POSTGRES_PORT=5432
+```
+
+#### 2. 配置 Nginx 反向代理
+
+创建 `nginx.conf`：
+
+```nginx
+upstream backend {
+    server localhost:8087;
+}
+
+upstream frontend {
+    server localhost:8086;
+}
+
+server {
+    listen 80;
+    server_name yourdomain.com;
+
+    # 重定向到 HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name yourdomain.com;
+
+    # SSL 证书配置
+    ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+
+    # 前端静态资源
+    location / {
+        proxy_pass http://frontend;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+
+    # 后端 API
+    location /api/ {
+        proxy_pass http://backend/api/;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+#### 3. 启用 HTTPS
+
+使用 Let's Encrypt 获取免费 SSL 证书：
+
+```bash
+# 安装 certbot
+sudo apt-get install certbot python3-certbot-nginx
+
+# 获取证书
+sudo certbot --nginx -d yourdomain.com
+
+# 自动续期
+sudo certbot renew --dry-run
+```
+
+#### 4. 配置数据库备份
+
+创建备份脚本 `backup.sh`：
+
+```bash
+#!/bin/bash
+
+BACKUP_DIR="/var/backups/lobster-memory"
+DATE=$(date +%Y%m%d_%H%M%S)
+BACKUP_FILE="$BACKUP_DIR/backup_$DATE.sql"
+
+# 创建备份目录
+mkdir -p $BACKUP_DIR
+
+# 执行备份
+docker-compose exec -T postgres pg_dump -U postgres lobster_memory > $BACKUP_FILE
+
+# 压缩备份
+gzip $BACKUP_FILE
+
+# 删除 7 天前的备份
+find $BACKUP_DIR -name "backup_*.sql.gz" -mtime +7 -delete
+
+echo "Backup completed: ${BACKUP_FILE}.gz"
+```
+
+添加定时任务：
+
+```bash
+# 编辑 crontab
+crontab -e
+
+# 每天凌晨 2 点执行备份
+0 2 * * * /path/to/backup.sh
+```
+
+### 更新部署
+
+#### 1. 拉取最新代码
+
+```bash
+git pull origin master
+```
+
+#### 2. 重新构建镜像
+
+```bash
+docker-compose build
+```
+
+#### 3. 重启服务
+
+```bash
+docker-compose up -d
+```
+
+#### 4. 执行数据库迁移（如有）
+
+```bash
+docker-compose exec backend python manage.py migrate
+```
+
+### 监控与维护
+
+#### 查看服务日志
+
+```bash
+# 查看所有服务日志
+docker-compose logs -f
+
+# 查看特定服务日志
+docker-compose logs -f backend
+docker-compose logs -f frontend
+docker-compose logs -f postgres
+
+# 查看最近 100 行日志
+docker-compose logs --tail=100 backend
+```
+
+#### 查看资源使用
+
+```bash
+# 查看容器资源使用情况
+docker stats
+
+# 查看磁盘使用
+docker system df
+
+# 清理未使用的资源
+docker system prune -a
+```
+
+#### 数据库维护
+
+```bash
+# 进入数据库容器
+docker-compose exec postgres psql -U postgres -d lobster_memory
+
+# 备份数据库
+docker-compose exec postgres pg_dump -U postgres lobster_memory > backup.sql
+
+# 恢复数据库
+docker-compose exec -T postgres psql -U postgres lobster_memory < backup.sql
+```
+
+### 故障排查
+
+#### 问题 1：容器启动失败
+
+```bash
+# 查看容器日志
+docker-compose logs backend
+
+# 检查端口占用
+sudo netstat -tulpn | grep -E '8086|8087|5432'
+
+# 重新构建镜像
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+#### 问题 2：数据库连接失败
+
+```bash
+# 检查数据库容器状态
+docker-compose ps postgres
+
+# 查看数据库日志
+docker-compose logs postgres
+
+# 测试数据库连接
+docker-compose exec postgres psql -U postgres -d lobster_memory -c "SELECT version();"
+```
+
+#### 问题 3：前端无法访问后端 API
+
+```bash
+# 检查后端服务状态
+curl http://localhost:8087/api/
+
+# 检查前端配置
+docker-compose logs frontend
+
+# 验证环境变量
+docker-compose exec frontend env | grep REACT_APP_API_URL
+```
+
+#### 问题 4：文件扫描失败
+
+```bash
+# 检查龙虾记忆目录挂载
+docker-compose exec backend ls -la /app/memory_files
+
+# 检查目录权限
+ls -ld /home/node/.openclaw/workspace/daotong
+
+# 重新挂载
+docker-compose down
+docker-compose up -d
+```
+
+### 卸载
+
+```bash
+# 停止并删除容器
+docker-compose down
+
+# 删除数据卷
+docker-compose down -v
+
+# 删除镜像
+docker rmi lobster-memory-sync-backend lobster-memory-sync-frontend
+
+# 删除项目目录
+cd ..
+rm -rf lobster-memory-sync
+```
+
+### 常见问题 (FAQ)
+
+**Q: 如何修改默认端口？**
+A: 在 `docker-compose.yml` 中修改对应的端口映射，例如：
