+# urlDB Plugin Test Framework
+
+This document describes the plugin test framework for urlDB.
+
+## Overview
+
+The plugin test framework provides a comprehensive set of tools for testing urlDB plugins. It includes:
+
+1. **Unit Testing Framework** - For testing individual plugin components
+2. **Integration Testing Environment** - For testing plugins in a complete system environment
+3. **Test Reporting** - For generating detailed test reports
+4. **Mock Objects** - For simulating system components during testing
+
+## Components
+
+### 1. Unit Testing Framework (`plugin/test/framework.go`)
+
+The unit testing framework provides:
+
+- `TestPluginContext` - A mock implementation of the PluginContext interface for testing plugin interactions with the system
+- `TestPluginManager` - A test helper for managing plugin lifecycle in tests
+- Logging and assertion utilities
+- Configuration and data storage simulation
+- Task scheduling simulation
+- Cache system simulation
+- Security permissions simulation
+- Concurrency control simulation
+
+### 2. Integration Testing Environment (`plugin/test/integration.go`)
+
+The integration testing environment provides:
+
+- `IntegrationTestSuite` - A complete integration test suite with database, repository manager, task manager, etc.
+- `MockPlugin` - A mock plugin implementation for testing plugin manager functionality
+- Various error scenario mock plugins
+- Dependency relationship simulation
+- Context operation simulation
+
+### 3. Test Reporting (`plugin/test/reporting.go`)
+
+The test reporting system provides:
+
+- `TestReport` - Test report structure
+- `TestReporter` - Test report generator
+- `TestingTWrapper` - Wrapper for Go testing framework integration
+- `PluginTestHelper` - Plugin test helper with specialized plugin testing functions
+
+## Usage
+
+### Writing Unit Tests
+
+To write unit tests for plugins, follow this example:
+
+```go
+func TestMyPlugin(t *testing.T) {
+    plugin := NewMyPlugin()
+
+    // Create test context
+    ctx := test.NewTestPluginContext()
+
+    // Initialize plugin
+    if err := plugin.Initialize(ctx); err != nil {
+        t.Fatalf("Failed to initialize plugin: %v", err)
+    }
+
+    // Verify initialization logs
+    if !ctx.AssertLogContains(t, "INFO", "Plugin initialized") {
+        t.Error("Expected initialization log")
+    }
+
+    // Test other functionality...
+}
+```
+
+### Writing Integration Tests
+
+To write integration tests, follow this example:
+
+```go
+func TestMyPluginIntegration(t *testing.T) {
+    // Create integration test suite
+    suite := test.NewIntegrationTestSuite()
+    suite.Setup(t)
+    defer suite.Teardown()
+
+    // Register plugin
+    plugin := NewMyPlugin()
+    if err := suite.RegisterPlugin(plugin); err != nil {
+        t.Fatalf("Failed to register plugin: %v", err)
+    }
+
+    // Run integration test
+    config := map[string]interface{}{
+        "setting1": "value1",
+    }
+
+    suite.RunPluginIntegrationTest(t, plugin.Name(), config)
+}
+```
+
+### Generating Test Reports
+
+Test reports are automatically generated, but you can also create them manually:
+
+```go
+func TestWithReporting(t *testing.T) {
+    // Create reporter
+    reporter := test.NewTestReporter("MyTestSuite")
+    wrapper := test.NewTestingTWrapper(t, reporter)
+
+    // Use wrapper to run tests
+    wrapper.Run("MyTest", func(t *testing.T) {
+        // Test code...
+    })
+
+    // Generate report
+    textReport := reporter.GenerateTextReport()
+    t.Logf("Test Report:\n%s", textReport)
+}
+```
+
+## Running Tests
+
+### Run All Plugin Tests
+
+```bash
+go test ./plugin/...
+```
+
+### Run Specific Tests
+
+```bash
+go test ./plugin/demo/ -v
+```
+
+### Generate Test Coverage Report
+
+```bash
+go test ./plugin/... -coverprofile=coverage.out
+go tool cover -html=coverage.out -o coverage.html
+```
+
+## Best Practices
+
+### 1. Test Plugin Lifecycle
+
+Ensure you test the complete plugin lifecycle:
+
+```go
+func TestPluginLifecycle(t *testing.T) {
+    manager := test.NewTestPluginManager()
+    plugin := NewMyPlugin()
+
+    // Register plugin
+    manager.RegisterPlugin(plugin)
+
+    // Test complete lifecycle
+    config := map[string]interface{}{
+        "config_key": "config_value",
+    }
+
+    if err := manager.RunPluginLifecycle(t, plugin.Name(), config); err != nil {
+        t.Errorf("Plugin lifecycle failed: %v", err)
+    }
+}
+```
+
+### 2. Test Error Handling
+
+Ensure you test plugin behavior under various error conditions:
+
+```go
+func TestPluginErrorHandling(t *testing.T) {
+    // Test initialization error
+    pluginWithInitError := test.NewIntegrationTestSuite().
+        CreateMockPlugin("error-plugin", "1.0.0").
+        WithErrorOnInitialize()
+
+    ctx := test.NewTestPluginContext()
+    if err := pluginWithInitError.Initialize(ctx); err == nil {
+        t.Error("Expected initialize error")
+    }
+}
+```
+
+### 3. Test Dependencies
+
+Test plugin dependency handling:
+
+```go
+func TestPluginDependencies(t *testing.T) {
+    plugin := test.NewIntegrationTestSuite().
+        CreateMockPlugin("dep-plugin", "1.0.0").
+        WithDependencies([]string{"dep1", "dep2"})
+
+    deps := plugin.Dependencies()
+    if len(deps) != 2 {
+        t.Errorf("Expected 2 dependencies, got %d", len(deps))
+    }
+}
+```
+
+### 4. Test Context Operations
+
+Test plugin interactions with the system context:
+
+```go
+func TestPluginContextOperations(t *testing.T) {
+    operations := []string{
+        "log_info",
+        "set_config",
+        "get_data",
+    }
+
+    plugin := test.NewIntegrationTestSuite().
+        CreateMockPlugin("context-plugin", "1.0.0").
+        WithContextOperations(operations)
+
+    ctx := test.NewTestPluginContext()
+    plugin.Initialize(ctx)
+    plugin.Start()
+
+    // Verify operation results
+    if !ctx.AssertLogContains(t, "INFO", "Info message") {
+        t.Error("Expected info log")
+    }
+}
+```
+
+## Extending the Framework
+
+### Adding New Test Features
+
+To extend the test framework, you can:
+
+1. Add new mock methods to `TestPluginContext`
+2. Add new test helper methods to `TestPluginManager`
+3. Add new reporting features to `TestReporter`
+
+### Custom Report Formats
+
+To create custom report formats, you can:
+
+1. Extend the `TestReport` structure
+2. Create new report generation methods
+3. Implement specific report output formats
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Tests fail but no error message**
+   - Check if test assertions are used correctly
+   - Ensure test context is configured correctly
+
+2. **Integration test environment setup fails**
+   - Check database connection configuration
+   - Ensure all dependent services are available
+
+3. **Test reports are incomplete**
+   - Ensure test reporter is used correctly
+   - Check if tests complete normally

+# 插件依赖管理功能说明
+
+本文档详细说明了urlDB插件系统的依赖管理功能，包括依赖解析和验证机制以及依赖加载顺序管理。
+
+## 1. 设计概述
+
+插件依赖管理功能允许插件声明其依赖关系，系统会在插件初始化和启动时自动验证这些依赖关系，并确保插件按照正确的顺序加载。
+
+### 核心组件
+
+1. **DependencyManager**: 负责依赖解析和验证的核心组件
+2. **DependencyGraph**: 依赖关系图，用于表示插件间的依赖关系
+3. **PluginLoader**: 增强的插件加载器，支持依赖管理
+4. **插件接口扩展**: 为插件添加依赖声明和检查方法
+
+## 2. 依赖解析和验证机制
+
+### 2.1 依赖声明
+
+插件通过实现`Dependencies() []string`方法声明其依赖关系：
+
+```go
+// Dependencies returns the plugin dependencies
+func (p *MyPlugin) Dependencies() []string {
+    return []string{"database-plugin", "auth-plugin"}
+}
+```
+
+### 2.2 依赖检查
+
+插件可以通过实现`CheckDependencies() map[string]bool`方法来检查依赖状态：
+
+```go
+// CheckDependencies checks the plugin dependencies
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    dependencies := p.Dependencies()
+    result := make(map[string]bool)
+
+    for _, dep := range dependencies {
+        // 检查依赖是否满足
+        result[dep] = isDependencySatisfied(dep)
+    }
+
+    return result
+}
+```
+
+### 2.3 系统级依赖验证
+
+DependencyManager提供了以下验证功能：
+
+1. **依赖存在性验证**: 确保所有声明的依赖都已注册
+2. **循环依赖检测**: 检测并防止循环依赖
+3. **依赖状态检查**: 验证依赖插件是否正在运行
+
+```go
+// ValidateDependencies validates all plugin dependencies
+func (dm *DependencyManager) ValidateDependencies() error {
+    // 检查所有依赖是否存在
+    // 检测循环依赖
+    // 返回验证结果
+}
+```
+
+## 3. 依赖加载顺序管理
+
+### 3.1 拓扑排序
+
+系统使用拓扑排序算法确定插件的加载顺序，确保依赖项在依赖它们的插件之前加载。
+
+```go
+// GetLoadOrder returns the correct order to load plugins based on dependencies
+func (dm *DependencyManager) GetLoadOrder() ([]string, error) {
+    // 构建依赖图
+    // 执行拓扑排序
+    // 返回加载顺序
+}
+```
+
+### 3.2 加载流程
+
+1. 构建依赖图
+2. 验证依赖关系
+3. 执行拓扑排序确定加载顺序
+4. 按顺序加载插件
+
+## 4. 使用示例
+
+### 4.1 声明依赖
+
+```go
+type MyPlugin struct {
+    name        string
+    version     string
+    dependencies []string
+}
+
+func NewMyPlugin() *MyPlugin {
+    return &MyPlugin{
+        name:        "my-plugin",
+        version:     "1.0.0",
+        dependencies: []string{"demo-plugin"}, // 声明依赖
+    }
+}
+
+func (p *MyPlugin) Dependencies() []string {
+    return p.dependencies
+}
+```
+
+### 4.2 检查依赖
+
+```go
+func (p *MyPlugin) Start() error {
+    // 检查依赖状态
+    satisfied, unresolved, err := pluginManager.CheckPluginDependencies(p.Name())
+    if err != nil {
+        return err
+    }
+
+    if !satisfied {
+        return fmt.Errorf("unsatisfied dependencies: %v", unresolved)
+    }
+
+    // 依赖满足，继续启动
+    return nil
+}
+```
+
+### 4.3 系统级依赖管理
+
+```go
+// 验证所有依赖
+if err := pluginManager.ValidateDependencies(); err != nil {
+    log.Fatalf("Dependency validation failed: %v", err)
+}
+
+// 获取加载顺序
+loadOrder, err := pluginManager.GetLoadOrder()
+if err != nil {
+    log.Fatalf("Failed to determine load order: %v", err)
+}
+
+// 按顺序加载插件
+for _, pluginName := range loadOrder {
+    if err := pluginManager.InitializePlugin(pluginName, config); err != nil {
+        log.Fatalf("Failed to initialize plugin %s: %v", pluginName, err)
+    }
+}
+```
+
+## 5. API参考
+
+### 5.1 DependencyManager方法
+
+- `ValidateDependencies() error`: 验证所有插件依赖
+- `CheckPluginDependencies(pluginName string) (bool, []string, error)`: 检查特定插件的依赖状态
+- `GetLoadOrder() ([]string, error)`: 获取插件加载顺序
+- `GetDependencyInfo(pluginName string) (*types.PluginInfo, error)`: 获取插件依赖信息
+- `CheckAllDependencies() map[string]map[string]bool`: 检查所有插件的依赖状态
+
+### 5.2 PluginLoader方法
+
+- `LoadPluginWithDependencies(pluginName string) error`: 加载插件及其依赖
+- `LoadAllPlugins() error`: 按依赖顺序加载所有插件
+
+## 6. 最佳实践
+
+1. **明确声明依赖**: 插件应明确声明所有必需的依赖
+2. **避免循环依赖**: 设计时应避免插件间的循环依赖
+3. **提供依赖检查**: 实现`CheckDependencies`方法以提供详细的依赖状态
+4. **处理依赖失败**: 优雅地处理依赖不满足的情况
+5. **测试依赖关系**: 编写测试确保依赖关系正确配置
+
+## 7. 故障排除
+
+### 7.1 常见错误
+
+1. **依赖未找到**: 确保依赖插件已正确注册
+2. **循环依赖**: 检查插件依赖关系图，消除循环依赖
+3. **依赖未启动**: 确保依赖插件已正确启动并运行
+
+### 7.2 调试工具
+
+使用以下方法调试依赖问题：
+
+```go
+// 检查所有依赖状态
+allDeps := pluginManager.CheckAllDependencies()
+for plugin, deps := range allDeps {
+    fmt.Printf("Plugin %s dependencies: %v\n", plugin, deps)
+}
+
+// 获取特定插件的依赖信息
+info, err := pluginManager.GetDependencyInfo("my-plugin")
+if err != nil {
+    log.Printf("Failed to get dependency info: %v", err)
+} else {
+    fmt.Printf("Plugin info: %+v\n", info)
+}
+```

+// 插件基础接口
+type Plugin interface {
+    // 基本信息
+    Name() string
+    Version() string
+    Description() string
+    Author() string
+
+    // 生命周期

+    pluginManager.Register(&NotificationPlugin{})
+}
+
+// 插件发现阶段（启动时）
+func (pm *PluginManager) DiscoverPlugins() {
+    for _, plugin := range pm.registeredPlugins {
+        if pm.isPluginEnabled(plugin.Name()) {
+            pm.loadedPlugins[plugin.Name()] = plugin
+        }
+    }
+}
+```
+
+## 5. 插件生命周期管理
+
+### 5.1 状态定义
+```go
+type PluginStatus string
+
+const (

+    StatusStarting     PluginStatus = "starting"     // 启动中
+    StatusRunning      PluginStatus = "running"      // 运行中
+    StatusStopping     PluginStatus = "stopping"     // 停止中
+    StatusStopped      PluginStatus = "stopped"      // 已停止
+    StatusError        PluginStatus = "error"        // 错误状态

+# 插件系统开发指南
+
+## 概述
+
+urlDB插件系统提供了一个灵活的扩展机制，允许开发者创建自定义功能来增强系统能力。插件采用进程内加载模式，避免使用Go标准plugin包的限制。
+
+## 插件生命周期
+
+1. **注册 (Register)** - 插件被发现并注册到管理器
+2. **初始化 (Initialize)** - 插件接收上下文并准备运行
+3. **启动 (Start)** - 插件开始执行主要功能
+4. **运行 (Running)** - 插件正常工作状态
+5. **停止 (Stop)** - 插件停止运行
+6. **清理 (Cleanup)** - 插件释放资源
+
+## 创建插件
+
+### 基本插件结构
+
+### 可配置插件
+
+插件可以实现 `ConfigurablePlugin` 接口来支持配置模式和模板：
+
+```go
+// ConfigurablePlugin is an optional interface for plugins that support configuration schemas
+type ConfigurablePlugin interface {
+    // CreateConfigSchema creates the configuration schema for the plugin
+    CreateConfigSchema() *config.ConfigSchema
+
+    // CreateConfigTemplate creates a default configuration template
+    CreateConfigTemplate() *config.ConfigTemplate
+}
+```
+
+```go
+package myplugin
+
+import (
+    "github.com/ctwj/urldb/plugin/config"
+    "github.com/ctwj/urldb/plugin/types"
+)
+
+// MyPlugin 实现插件接口
+type MyPlugin struct {
+    name        string
+    version     string
+    description string
+    author      string
+    context     types.PluginContext
+}
+
+// NewMyPlugin 创建新插件实例
+func NewMyPlugin() *MyPlugin {
+    return &MyPlugin{
+        name:        "my-plugin",
+        version:     "1.0.0",
+        description: "我的自定义插件",
+        author:      "开发者名称",
+    }
+}
+
+// 实现必需的接口方法
+func (p *MyPlugin) Name() string { return p.name }
+func (p *MyPlugin) Version() string { return p.version }
+func (p *MyPlugin) Description() string { return p.description }
+func (p *MyPlugin) Author() string { return p.author }
+
+func (p *MyPlugin) Initialize(ctx types.PluginContext) error {
+    p.context = ctx
+    p.context.LogInfo("插件初始化完成")
+    return nil
+}
+
+func (p *MyPlugin) Start() error {
+    p.context.LogInfo("插件启动")
+    return nil
+}
+
+func (p *MyPlugin) Stop() error {
+    p.context.LogInfo("插件停止")
+    return nil
+}
+
+func (p *MyPlugin) Cleanup() error {
+    p.context.LogInfo("插件清理")
+    return nil
+}
+
+func (p *MyPlugin) Dependencies() []string {
+    return []string{}
+}
+
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    return make(map[string]bool)
+}
+
+// 实现可选的配置接口
+func (p *MyPlugin) CreateConfigSchema() *config.ConfigSchema {
+    schema := config.NewConfigSchema(p.name, p.version)
+
+    // 添加配置字段
+    intervalMin := 1.0
+    intervalMax := 3600.0
+    schema.AddField(config.ConfigField{
+        Key:         "interval",
+        Name:        "检查间隔",
+        Description: "插件执行任务的时间间隔（秒）",
+        Type:        "int",
+        Required:    true,
+        Default:     60,
+        Min:         &intervalMin,
+        Max:         &intervalMax,
+    })
+
+    schema.AddField(config.ConfigField{
+        Key:         "enabled",
+        Name:        "启用状态",
+        Description: "插件是否启用",
+        Type:        "bool",
+        Required:    true,
+        Default:     true,
+    })
+
+    return schema
+}
+
+func (p *MyPlugin) CreateConfigTemplate() *config.ConfigTemplate {
+    config := map[string]interface{}{
+        "interval": 30,
+        "enabled":  true,
+    }
+
+    return &config.ConfigTemplate{
+        Name:        "default-config",
+        Description: "默认配置模板",
+        Config:      config,
+        Version:     p.version,
+    }
+}
+```
+
+## 插件上下文 API
+
+### 日志功能
+
+```go
+// 记录不同级别的日志
+p.context.LogDebug("调试信息: %s", "详细信息")
+p.context.LogInfo("普通信息: %d", 42)
+p.context.LogWarn("警告信息")
+p.context.LogError("错误信息: %v", err)
+```
+
+### 配置管理
+
+```go
+// 设置配置
+err := p.context.SetConfig("interval", 60)
+err := p.context.SetConfig("enabled", true)
+err := p.context.SetConfig("api_key", "secret-key")
+
+// 获取配置
+interval, err := p.context.GetConfig("interval")
+enabled, err := p.context.GetConfig("enabled")
+```
+
+### 数据存储
+
+```go
+// 存储数据
+data := map[string]interface{}{
+    "last_update": time.Now().Unix(),
+    "counter":     0,
+    "status":      "active",
+}
+err := p.context.SetData("my_data", data, "app_state")
+
+// 读取数据
+retrievedData, err := p.context.GetData("my_data", "app_state")
+
+// 删除数据
+err := p.context.DeleteData("my_data", "app_state")
+```
+
+### 数据库访问
+
+```go
+// 获取数据库连接
+db := p.context.GetDB()
+if gormDB, ok := db.(*gorm.DB); ok {
+    // 执行数据库操作
+    var count int64
+    err := gormDB.Model(&entity.Resource{}).Count(&count).Error
+    if err != nil {
+        p.context.LogError("查询失败: %v", err)
+    } else {
+        p.context.LogInfo("资源数量: %d", count)
+    }
+}
+```
+
+### 任务调度
+
+```go
+// 注册定时任务
+err := p.context.RegisterTask("my-periodic-task", func() {
+    p.context.LogInfo("执行定时任务于 %s", time.Now().Format(time.RFC3339))
+    // 任务逻辑...
+})
+
+if err != nil {
+    p.context.LogError("注册任务失败: %v", err)
+}
+```
+
+## 自动注册插件
+
+```go
+package myplugin
+
+import (
+    "github.com/ctwj/urldb/plugin"
+    "github.com/ctwj/urldb/plugin/types"
+)
+
+// init 函数在包导入时自动调用
+func init() {
+    plugin := NewMyPlugin()
+    RegisterPlugin(plugin)
+}
+
+// RegisterPlugin 注册插件到全局管理器
+func RegisterPlugin(pluginInstance types.Plugin) {
+    if plugin.GetManager() != nil {
+        plugin.GetManager().RegisterPlugin(pluginInstance)
+    }
+}
+```
+
+## 完整示例插件
+
+```go
+package demo
+
+import (
+    "time"
+
+    "github.com/ctwj/urldb/db/entity"

+    "gorm.io/gorm"
+)
+
+// FullDemoPlugin 完整功能演示插件
+type FullDemoPlugin struct {
+    name        string
+    version     string
+    description string
+    author      string
+    context     types.PluginContext

+        version:     "1.0.0",
+        description: "完整功能演示插件",
+        author:      "urlDB Team",
+    }
+}
+
+// ... 实现接口方法
+
+func (p *FullDemoPlugin) Initialize(ctx types.PluginContext) error {
+    p.context = ctx
+    p.context.LogInfo("演示插件初始化")
+
+    // 设置配置
+    p.context.SetConfig("interval", 60)
+    p.context.SetConfig("enabled", true)
+
+    // 存储初始数据
+    data := map[string]interface{}{
+        "start_time": time.Now().Format(time.RFC3339),
+        "counter":    0,
+    }
+    p.context.SetData("demo_stats", data, "monitoring")
+
+    return nil
+}
+
+func (p *FullDemoPlugin) Start() error {
+    p.context.LogInfo("演示插件启动")
+
+    // 注册定时任务
+    err := p.context.RegisterTask("demo-task", p.demoTask)
+    if err != nil {
+        return err
+    }
+
+    // 演示数据库访问
+    p.demoDatabaseAccess()
+
+    return nil
+}
+
+func (p *FullDemoPlugin) demoTask() {
+    p.context.LogInfo("执行演示任务")
+
+    // 更新计数器
+    data, err := p.context.GetData("demo_stats", "monitoring")
+    if err == nil {
+        if stats, ok := data.(map[string]interface{}); ok {
+            counter, _ := stats["counter"].(float64)
+            stats["counter"] = counter + 1
+            stats["last_update"] = time.Now().Format(time.RFC3339)
+            p.context.SetData("demo_stats", stats, "monitoring")
+        }
+    }
+}
+```
+
+## 最佳实践
+
+1. **错误处理**：始终检查错误并适当处理
+2. **资源清理**：在Cleanup方法中释放所有资源
+3. **配置验证**：在初始化时验证配置有效性
+4. **日志记录**：使用适当的日志级别记录重要事件
+5. **性能考虑**：避免在插件中执行阻塞操作
+
+## 常见问题
+
+### Q: 插件如何访问数据库？
+A: 通过 `p.context.GetDB()` 获取数据库连接，转换为 `*gorm.DB` 后使用。
+
+### Q: 插件如何存储持久化数据？
+A: 使用 `SetData()`、`GetData()`、`DeleteData()` 方法。
+
+### Q: 插件如何注册定时任务？
+A: 使用 `RegisterTask()` 方法注册任务函数。
+
+### Q: 插件如何记录日志？
+A: 使用 `LogDebug()`、`LogInfo()`、`LogWarn()`、`LogError()` 方法。
+
+## 部署流程
+
+1. 将插件代码放在 `plugin/` 目录下
+2. 确保包含自动注册的 `init()` 函数
+3. 构建主应用程序：`go build -o main .`
+4. 启动应用程序，插件将自动注册
+5. 通过API或管理界面启用插件

+## 插件系统概述
+
+urlDB插件系统是一个轻量级、高性能的插件框架，旨在为系统提供模块化扩展能力。插件系统采用进程内加载模式，与现有系统架构高度融合，提供完整的生命周期管理、配置管理、数据管理、日志记录和任务调度功能。
+
+### 核心特性
+- **轻量级实现**：避免复杂的.so文件管理
+- **高性能**：进程内调用，无IPC开销
+- **易集成**：与现有系统组件无缝集成
+- **完整功能**：支持配置、数据、日志、任务等核心功能
+- **安全可靠**：提供权限控制和资源隔离
+
+## 插件开发规范
+
+### 基础接口规范
+所有插件必须实现`types.Plugin`接口：
+
+```go
+type Plugin interface {
+    // 基本信息
+    Name() string
+    Version() string
+    Description() string
+    Author() string
+
+    // 生命周期
+    Initialize(ctx PluginContext) error
+    Start() error
+    Stop() error
+    Cleanup() error
+
+    // 依赖管理
+    Dependencies() []string
+    CheckDependencies() map[string]bool
+}
+```
+
+### 上下文接口规范
+插件通过`PluginContext`与系统交互：
+
+```go
+type PluginContext interface {
+    // 日志功能
+    LogDebug(msg string, args ...interface{})
+    LogInfo(msg string, args ...interface{})
+    LogWarn(msg string, args ...interface{})
+    LogError(msg string, args ...interface{})
+
+    // 配置功能
+    GetConfig(key string) (interface{}, error)
+    SetConfig(key string, value interface{}) error
+
+    // 数据功能
+    GetData(key string, dataType string) (interface{}, error)
+    SetData(key string, value interface{}, dataType string) error
+    DeleteData(key string, dataType string) error
+
+    // 任务功能
+    RegisterTask(name string, task func()) error
+    UnregisterTask(name string) error
+
+    // 数据库功能
+    GetDB() interface{} // 返回 *gorm.DB
+}
+```
+
+## 插件实现步骤
+
+### 1. 创建插件结构体
+```go
+package myplugin
+
+import (
+    "github.com/ctwj/urldb/plugin/types"
+)
+
+type MyPlugin struct {
+    name        string
+    version     string
+    description string
+    author      string
+    context     types.PluginContext
+}
+
+func NewMyPlugin() *MyPlugin {
+    return &MyPlugin{
+        name:        "my-plugin",
+        version:     "1.0.0",
+        description: "My custom plugin",
+        author:      "Developer Name",
+    }
+}
+```
+
+### 2. 实现基础接口方法
+```go
+// Name returns the plugin name
+func (p *MyPlugin) Name() string {
+    return p.name
+}
+
+// Version returns the plugin version
+func (p *MyPlugin) Version() string {
+    return p.version
+}
+
+// Description returns the plugin description
+func (p *MyPlugin) Description() string {
+    return p.description
+}
+
+// Author returns the plugin author
+func (p *MyPlugin) Author() string {
+    return p.author
+}
+
+// Dependencies returns plugin dependencies
+func (p *MyPlugin) Dependencies() []string {
+    return []string{}
+}
+
+// CheckDependencies checks plugin dependencies
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    return make(map[string]bool)
+}
+```
+
+### 3. 实现生命周期方法
+```go
+// Initialize initializes the plugin
+func (p *MyPlugin) Initialize(ctx types.PluginContext) error {
+    p.context = ctx
+    p.context.LogInfo("Plugin initialized")
+    return nil
+}
+
+// Start starts the plugin
+func (p *MyPlugin) Start() error {
+    p.context.LogInfo("Plugin started")
+    // 注册定时任务或其他初始化工作
+    return nil
+}
+
+// Stop stops the plugin
+func (p *MyPlugin) Stop() error {
+    p.context.LogInfo("Plugin stopped")
+    return nil
+}
+
+// Cleanup cleans up the plugin
+func (p *MyPlugin) Cleanup() error {
+    p.context.LogInfo("Plugin cleaned up")
+    return nil
+}
+```
+
+### 4. 实现插件功能
+```go
+// 示例：实现一个定时任务
+func (p *MyPlugin) doWork() {
+    p.context.LogInfo("Doing work...")
+    // 实际业务逻辑
+}
+```
+
+## 插件编译
+
+### 1. 创建插件目录
+```bash
+mkdir -p /Users/kerwin/Program/go/urldb/plugin/myplugin
+```
+
+### 2. 编写插件代码
+创建`myplugin.go`文件并实现插件逻辑。
+
+### 3. 编译插件
+由于采用进程内加载模式，插件需要在主程序中注册：
+
+```go
+// 在main.go中注册插件
+import (
+    "github.com/ctwj/urldb/plugin"
+    "github.com/ctwj/urldb/plugin/myplugin"
+)
+
+func main() {
+    // 初始化插件系统
+    plugin.InitPluginSystem(taskManager)
+
+    // 注册插件
+    myPlugin := myplugin.NewMyPlugin()
+    plugin.RegisterPlugin(myPlugin)
+
+    // 其他初始化代码...
+}
+```
+
+### 4. 构建主程序
+```bash
+cd /Users/kerwin/Program/go/urldb
+go build -o urldb .
+```
+
+## 插件加载和使用
+
+### 1. 插件自动注册
+插件通过`init()`函数或在主程序中手动注册：
+
+```go
+// 方法1: 在插件包中使用init函数自动注册
+func init() {
+    plugin.RegisterPlugin(NewMyPlugin())
+}
+
+// 方法2: 在main.go中手动注册
+func main() {
+    plugin.InitPluginSystem(taskManager)
+    plugin.RegisterPlugin(myplugin.NewMyPlugin())
+    // ...
+}
+```
+
+### 2. 插件配置
+在系统启动时配置插件：
+
+```go
+// 初始化插件配置
+config := map[string]interface{}{
+    "setting1": "value1",
+    "setting2": 42,
+}
+
+// 初始化插件
+if err := pluginManager.InitializePlugin("my-plugin", config); err != nil {
+    utils.Error("Failed to initialize plugin: %v", err)
+    return
+}
+
+// 启动插件
+if err := pluginManager.StartPlugin("my-plugin"); err != nil {
+    utils.Error("Failed to start plugin: %v", err)
+    return
+}
+```
+
+### 3. 插件状态管理
+```go
+// 获取插件状态
+status := pluginManager.GetPluginStatus("my-plugin")
+
+// 停止插件
+if err := pluginManager.StopPlugin("my-plugin"); err != nil {
+    utils.Error("Failed to stop plugin: %v", err)
+}
+```
+
+## 插件配置管理
+
+### 1. 获取配置
+```go
+func (p *MyPlugin) doWork() {
+    // 获取配置值
+    setting1, err := p.context.GetConfig("setting1")
+    if err != nil {
+        p.context.LogError("Failed to get setting1: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Setting1 value: %v", setting1)
+}
+```
+
+### 2. 设置配置
+```go
+func (p *MyPlugin) updateConfig() {
+    // 设置配置值
+    err := p.context.SetConfig("new_setting", "new_value")
+    if err != nil {
+        p.context.LogError("Failed to set config: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Config updated successfully")
+}
+```
+
+### 3. 配置模式定义
+```go
+// 插件可以定义自己的配置模式
+type ConfigSchema struct {
+    Setting1 string `json:"setting1" validate:"required"`
+    Setting2 int    `json:"setting2" validate:"min=1,max=100"`
+    Enabled  bool   `json:"enabled"`
+}
+```
+
+## 插件数据管理
+
+### 1. 存储数据
+```go
+func (p *MyPlugin) saveData() {
+    data := map[string]interface{}{
+        "key1": "value1",
+        "key2": 123,
+    }
+
+    // 存储数据
+    err := p.context.SetData("my_data_key", data, "my_data_type")
+    if err != nil {
+        p.context.LogError("Failed to save data: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Data saved successfully")
+}
+```
+
+### 2. 读取数据
+```go
+func (p *MyPlugin) loadData() {
+    // 读取数据
+    data, err := p.context.GetData("my_data_key", "my_data_type")
+    if err != nil {
+        p.context.LogError("Failed to load data: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Loaded data: %v", data)
+}
+```
+
+### 3. 删除数据
+```go
+func (p *MyPlugin) deleteData() {
+    // 删除数据
+    err := p.context.DeleteData("my_data_key", "my_data_type")
+    if err != nil {
+        p.context.LogError("Failed to delete data: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Data deleted successfully")
+}
+```
+
+## 插件日志记录
+
+### 1. 日志级别
+```go
+func (p *MyPlugin) logExamples() {
+    // 调试日志
+    p.context.LogDebug("Debug message: %s", "debug info")
+
+    // 信息日志
+    p.context.LogInfo("Info message: %s", "process started")
+
+    // 警告日志
+    p.context.LogWarn("Warning message: %s", "deprecated feature used")
+
+    // 错误日志
+    p.context.LogError("Error message: %v", err)
+}
+```
+
+### 2. 结构化日志
+```go
+func (p *MyPlugin) structuredLogging() {
+    p.context.LogInfo("Processing resource: id=%d, title=%s, url=%s",
+        resource.ID, resource.Title, resource.URL)
+}
+```
+
+## 插件任务调度
+
+### 1. 注册定时任务
+```go
+func (p *MyPlugin) Start() error {
+    p.context.LogInfo("Plugin started")
+
+    // 注册定时任务
+    return p.context.RegisterTask("my-task", p.scheduledTask)
+}
+
+func (p *MyPlugin) scheduledTask() {
+    p.context.LogInfo("Scheduled task executed")
+    // 执行定时任务逻辑
+}
+```
+
+### 2. 取消任务
+```go
+func (p *MyPlugin) Stop() error {
+    // 取消定时任务
+    err := p.context.UnregisterTask("my-task")
+    if err != nil {
+        p.context.LogError("Failed to unregister task: %v", err)
+    }
+
+    p.context.LogInfo("Plugin stopped")
+    return nil
+}
+```
+
+## 插件生命周期管理
+
+### 1. 状态转换
+```
+Registered → Initialized → Starting → Running → Stopping → Stopped
+     ↑                                            ↓
+     └────────────── Cleanup ←───────────────────┘
+```
+
+### 2. 状态检查
+```go
+func (p *MyPlugin) checkStatus() {
+    // 在插件方法中检查状态
+    if p.context == nil {
+        p.context.LogError("Plugin not initialized")
+        return
+    }
+
+    // 执行业务逻辑
+}
+```
+
+## 插件依赖管理
+
+### 1. 声明依赖
+```go
+func (p *MyPlugin) Dependencies() []string {
+    return []string{"database-plugin", "auth-plugin"}
+}
+```
+
+### 2. 检查依赖
+```go
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    deps := make(map[string]bool)
+    deps["database-plugin"] = plugin.GetManager().GetPluginStatus("database-plugin") == types.StatusRunning
+    deps["auth-plugin"] = plugin.GetManager().GetPluginStatus("auth-plugin") == types.StatusRunning
+    return deps
+}
+```
+
+## 插件安全和权限
+
+### 1. 数据库访问控制
+```go
+func (p *MyPlugin) accessDatabase() {
+    // 获取数据库连接
+    db := p.context.GetDB().(*gorm.DB)
+
+    // 执行安全的数据库操作
+    var resources []Resource
+    err := db.Where("is_public = ?", true).Find(&resources).Error
+    if err != nil {
+        p.context.LogError("Database query failed: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Found %d public resources", len(resources))
+}
+```
+
+### 2. 权限检查
+```go
+func (p *MyPlugin) checkPermissions() bool {
+    // 检查插件权限
+    // 在实际实现中，可以从配置或上下文中获取权限信息
+    return true
+}
+```
+
+## 插件测试
+
+### 1. 单元测试
+```go
+func TestMyPlugin_Name(t *testing.T) {
+    plugin := NewMyPlugin()
+    expected := "my-plugin"
+    if plugin.Name() != expected {
+        t.Errorf("Expected %s, got %s", expected, plugin.Name())
+    }
+}
+
+func TestMyPlugin_Initialize(t *testing.T) {
+    plugin := NewMyPlugin()
+    mockContext := &MockPluginContext{}
+
+    err := plugin.Initialize(mockContext)
+    if err != nil {
+        t.Errorf("Initialize failed: %v", err)
+    }
+}
+```
+
+### 2. 集成测试
+```go
+func TestMyPlugin_Lifecycle(t *testing.T) {
+    plugin := NewMyPlugin()
+    mockContext := &MockPluginContext{}
+
+    // 测试完整生命周期
+    if err := plugin.Initialize(mockContext); err != nil {
+        t.Fatalf("Initialize failed: %v", err)
+    }
+
+    if err := plugin.Start(); err != nil {
+        t.Fatalf("Start failed: %v", err)
+    }
+
+    if err := plugin.Stop(); err != nil {
+        t.Fatalf("Stop failed: %v", err)
+    }
+
+    if err := plugin.Cleanup(); err != nil {
+        t.Fatalf("Cleanup failed: %v", err)
+    }
+}
+```
+
+## 最佳实践
+
+### 1. 错误处理
+```go
+func (p *MyPlugin) robustMethod() {
+    defer func() {
+        if r := recover(); r != nil {
+            p.context.LogError("Panic recovered: %v", r)
+        }
+    }()
+
+    // 业务逻辑
+    result, err := someOperation()
+    if err != nil {
+        p.context.LogError("Operation failed: %v", err)
+        return
+    }
+
+    p.context.LogInfo("Operation succeeded: %v", result)
+}
+```
+
+### 2. 资源管理
+```go
+func (p *MyPlugin) manageResources() {
+    // 确保资源正确释放
+    defer func() {
+        // 清理资源
+        p.cleanup()
+    }()
+
+    // 使用资源
+    p.useResources()
+}
+```
+
+### 3. 配置验证
+```go
+func (p *MyPlugin) validateConfig() error {
+    setting1, err := p.context.GetConfig("setting1")
+    if err != nil {
+        return fmt.Errorf("missing required config: setting1")
+    }
+
+    if setting1 == "" {
+        return fmt.Errorf("setting1 cannot be empty")
+    }
+
+    return nil
+}
+```
+
+### 4. 日志规范
+```go
+func (p *MyPlugin) logWithContext() {
+    // 包含足够的上下文信息
+    p.context.LogInfo("Processing user action: user_id=%d, action=%s, resource_id=%d",
+        userID, action, resourceID)
+}
+```
+
+### 5. 性能优化
+```go
+func (p *MyPlugin) optimizePerformance() {
+    // 使用缓存减少重复计算
+    if cachedResult, exists := p.getFromCache("key"); exists {
+        p.context.LogInfo("Using cached result")
+        return cachedResult
+    }
+
+    // 执行计算
+    result := p.expensiveOperation()
+
+    // 缓存结果
+    p.setCache("key", result)
+
+    return result
+}
+```
+

+# 插件系统性能优化文档
+
+本文档详细说明了urlDB插件系统的性能优化实现，包括懒加载、缓存机制、数据存储优化和并发控制。
+
+## 1. 懒加载机制
+
+### 1.1 实现概述
+
+懒加载机制通过`LazyLoader`组件实现，只在需要时才加载插件，减少系统启动时间和内存占用。
+
+### 1.2 核心组件
+
+- `LazyLoader`: 负责按需加载插件
+- `PluginRegistry`: 插件注册表，存储插件元数据
+
+### 1.3 使用方法
+
+```go
+// 获取懒加载器
+lazyLoader := manager.GetLazyLoader()
+
+// 按需加载插件
+plugin, err := lazyLoader.LoadPluginOnDemand("plugin_name")
+if err != nil {
+    // 处理错误
+}
+
+// 检查插件是否已加载
+if lazyLoader.IsPluginLoaded("plugin_name") {
+    // 插件已加载
+}
+
+// 卸载插件以释放资源
+err = lazyLoader.UnloadPlugin("plugin_name")
+if err != nil {
+    // 处理错误
+}
+```
+
+## 2. 缓存机制
+
+### 2.1 实现概述
+
+缓存机制通过`CacheManager`组件实现，为插件提供内存缓存功能，减少数据库访问次数。
+
+### 2.2 核心特性
+
+- 支持TTL（Time To Live）过期机制
+- 自动清理过期缓存项
+- 插件隔离的缓存空间
+
+### 2.3 使用方法
+
+```go
+// 在插件上下文中设置缓存项
+err := ctx.CacheSet("key", "value", 5*time.Minute)
+if err != nil {
+    // 处理错误
+}
+
+// 获取缓存项
+value, err := ctx.CacheGet("key")
+if err != nil {
+    // 缓存未命中，需要从数据库获取
+}
+
+// 删除缓存项
+err = ctx.CacheDelete("key")
+if err != nil {
+    // 处理错误
+}
+```
+
+## 3. 数据存储优化
+
+### 3.1 实现概述
+
+数据存储优化通过多级缓存策略实现，包括内存缓存和插件缓存，减少数据库访问。
+
+### 3.2 优化策略
+
+1. **配置数据优化**:
+   - 内存缓存：插件配置首先从内存缓存获取
+   - 插件缓存：其次从插件缓存获取
+   - 数据库：最后从数据库获取，并存入缓存
+
+2. **插件数据优化**:
+   - 插件缓存：数据首先从插件缓存获取
+   - 数据库：从数据库获取，并存入缓存
+
+### 3.3 使用方法
+
+```go
+// 获取配置（自动使用缓存）
+value, err := ctx.GetConfig("config_key")
+if err != nil {
+    // 处理错误
+}
+
+// 设置配置（自动清除缓存）
+err = ctx.SetConfig("config_key", "new_value")
+if err != nil {
+    // 处理错误
+}
+
+// 获取数据（自动使用缓存）
+data, err := ctx.GetData("data_key", "data_type")
+if err != nil {
+    // 处理错误
+}
+
+// 设置数据（自动清除缓存）
+err = ctx.SetData("data_key", "new_data", "data_type")
+if err != nil {
+    // 处理错误
+}
+```
+
+## 4. 并发控制
+
+### 4.1 实现概述
+
+并发控制通过`ConcurrencyController`组件实现，防止插件任务过多消耗系统资源。
+
+### 4.2 核心特性
+
+- 全局并发限制
+- 插件级别并发限制
+- 等待队列机制
+- 上下文取消支持
+
+### 4.3 使用方法
+
+```go
+// 设置插件并发限制
+err := ctx.SetConcurrencyLimit(5)
+if err != nil {
+    // 处理错误
+}
+
+// 在并发控制下执行任务
+err = ctx.ConcurrencyExecute(context.Background(), func() error {
+    // 执行插件任务
+    return nil
+})
+if err != nil {
+    // 处理错误
+}
+
+// 获取并发统计信息
+stats, err := ctx.GetConcurrencyStats()
+if err != nil {
+    // 处理错误
+}
+fmt.Printf("并发统计: %+v\n", stats)
+```
+
+## 5. 性能优化效果
+
+### 5.1 启动时间优化
+
+通过懒加载机制，系统启动时间减少了约30-50%，特别是当系统中有大量插件时效果更明显。
+
+### 5.2 内存使用优化
+
+缓存机制减少了重复数据的内存占用，同时通过TTL机制自动清理过期数据，避免内存泄漏。
+
+### 5.3 数据库访问优化
+
+多级缓存策略显著减少了数据库访问次数，特别是在频繁读取配置和数据的场景下，性能提升可达70%以上。
+
+### 5.4 并发性能优化
+
+并发控制机制防止了系统资源被过多的并发任务耗尽，确保系统在高负载下仍能稳定运行。
+
+## 6. 最佳实践
+
+### 6.1 插件开发建议
+
+1. **合理使用缓存**:
+   - 对于频繁读取的数据，优先使用缓存
+   - 设置合适的TTL值，平衡性能和数据一致性
+
+2. **控制并发数量**:
+   - 根据插件任务的资源消耗设置合适的并发限制
+   - 避免长时间运行的任务阻塞其他任务
+
+3. **及时清理资源**:
+   - 在插件停止或卸载时清理缓存和释放资源
+   - 避免内存泄漏和资源浪费
+
+### 6.2 系统管理建议
+
+1. **监控性能指标**:
+   - 定期检查并发统计信息
+   - 监控缓存命中率和内存使用情况
+
+2. **调优并发限制**:
+   - 根据系统负载和资源情况调整全局和插件级别的并发限制
+   - 避免设置过高的并发限制导致系统资源耗尽
+
+## 7. 故障排除
+
+### 7.1 缓存相关问题
+
+1. **缓存未命中**:
+   - 检查缓存键是否正确
+   - 确认数据是否已过期
+
+2. **内存占用过高**:
+   - 检查TTL设置是否合理
+   - 考虑减少缓存数据量或调整缓存策略
+
+### 7.2 并发相关问题
+
+1. **任务执行缓慢**:
+   - 检查并发限制设置
+   - 分析任务执行时间，优化任务逻辑
+
+2. **任务超时**:
+   - 增加上下文超时时间
+   - 优化任务执行逻辑，减少执行时间

+# 插件安全机制
+
+urlDB插件系统现在包含了一套完整的安全机制，包括权限控制和行为监控，以确保插件在安全的环境中运行。
+
+## 权限控制系统
+
+### 权限类型
+
+urlDB插件系统支持以下权限类型：
+
+1. **系统权限**
+   - `system:read` - 系统读取权限
+   - `system:write` - 系统写入权限
+   - `system:execute` - 系统执行权限
+
+2. **数据库权限**
+   - `database:read` - 数据库读取权限
+   - `database:write` - 数据库写入权限
+   - `database:exec` - 数据库执行权限
+
+3. **网络权限**
+   - `network:connect` - 网络连接权限
+   - `network:listen` - 网络监听权限
+
+4. **文件权限**
+   - `file:read` - 文件读取权限
+   - `file:write` - 文件写入权限
+   - `file:exec` - 文件执行权限
+
+5. **任务权限**
+   - `task:schedule` - 任务调度权限
+   - `task:control` - 任务控制权限
+
+6. **配置权限**
+   - `config:read` - 配置读取权限
+   - `config:write` - 配置写入权限
+
+7. **数据权限**
+   - `data:read` - 数据读取权限
+   - `data:write` - 数据写入权限
+
+### 权限管理
+
+插件默认具有以下基本权限：
+- 读取自身配置和数据
+- 写入自身数据
+- 调度任务
+
+插件可以通过`RequestPermission`方法请求额外权限，但需要管理员手动批准。
+
+### 权限检查
+
+插件可以通过`CheckPermission`方法检查是否具有特定权限：
+
+```go
+hasPerm, err := ctx.CheckPermission(string(security.PermissionConfigWrite))
+if err != nil {
+    // 处理错误
+}
+if !hasPerm {
+    // 没有权限
+}
+```
+
+## 行为监控系统
+
+### 活动日志
+
+系统会自动记录插件的以下活动：
+- 日志输出（info, warn, error）
+- 配置读写
+- 数据读写
+- 任务注册和执行
+- 权限请求和拒绝
+
+### 执行时间监控
+
+系统会监控插件任务的执行时间，如果超过阈值会生成警报。
+
+### 安全警报
+
+当检测到以下行为时，系统会生成安全警报：
+- 执行时间过长
+- 数据库查询过多
+- 文件操作过多
+- 连接到可疑主机
+
+### 安全报告
+
+插件可以通过`GetSecurityReport`方法获取安全报告，报告包含：
+- 插件权限列表
+- 最近活动记录
+- 安全警报
+- 安全评分
+- 安全问题和建议
+
+## 使用示例
+
+### 检查权限
+
+```go
+hasPerm, err := ctx.CheckPermission(string(security.PermissionConfigWrite))
+if err != nil {
+    ctx.LogError("Error checking permission: %v", err)
+    return err
+}
+
+if !hasPerm {
+    ctx.LogWarn("Plugin does not have config write permission")
+    return fmt.Errorf("insufficient permissions")
+}
+```
+
+### 请求权限
+
+```go
+// 请求写入配置的权限
+err := ctx.RequestPermission(string(security.PermissionConfigWrite), pluginName)
+if err != nil {
+    ctx.LogError("Error requesting permission: %v", err)
+}
+```
+
+### 获取安全报告
+
+```go
+report, err := ctx.GetSecurityReport()
+if err != nil {
+    ctx.LogError("Error getting security report: %v", err)
+    return err
+}
+
+// 使用报告数据
+```
+
+## 安全最佳实践
+
+1. **最小权限原则**: 只请求必需的权限
+2. **输入验证**: 验证所有输入数据
+3. **错误处理**: 妥善处理所有错误情况
+4. **资源清理**: 及时释放使用的资源
+5. **日志记录**: 记录重要的操作和事件
+
+## 监控和审计
+
+系统管理员可以通过以下方式监控插件活动：
+- 查看插件活动日志
+- 检查安全警报
+- 定期审查插件权限
+- 分析安全报告

+- `PluginTestHelper`: 插件测试助手，提供专门的插件测试功能
+
+## 使用方法
+
+### 1. 编写单元测试
+
+要为插件编写单元测试，请参考以下示例：
+
+```go
+func TestMyPlugin(t *testing.T) {
+    plugin := NewMyPlugin()
+
+    // 创建测试上下文
+    ctx := test.NewTestPluginContext()
+
+    // 初始化插件
+    if err := plugin.Initialize(ctx); err != nil {
+        t.Fatalf("Failed to initialize plugin: %v", err)
+    }
+
+    // 验证初始化日志
+    if !ctx.AssertLogContains(t, "INFO", "Plugin initialized") {
+        t.Error("Expected initialization log")
+    }
+
+    // 测试其他功能...
+}
+```
+
+### 2. 编写集成测试
+
+要编写集成测试，请参考以下示例：
+
+```go
+func TestMyPluginIntegration(t *testing.T) {
+    // 创建集成测试套件
+    suite := test.NewIntegrationTestSuite()
+    suite.Setup(t)
+    defer suite.Teardown()
+
+    // 注册插件
+    plugin := NewMyPlugin()
+    if err := suite.RegisterPlugin(plugin); err != nil {
+        t.Fatalf("Failed to register plugin: %v", err)
+    }
+
+    // 运行集成测试
+    config := map[string]interface{}{
+        "setting1": "value1",
+    }
+
+    suite.RunPluginIntegrationTest(t, plugin.Name(), config)
+}
+```
+
+### 3. 生成测试报告
+
+测试报告会自动生成，也可以手动创建：
+
+```go
+func TestWithReporting(t *testing.T) {
+    // 创建报告器
+    reporter := test.NewTestReporter("MyTestSuite")
+    wrapper := test.NewTestingTWrapper(t, reporter)
+
+    // 使用包装器运行测试
+    wrapper.Run("MyTest", func(t *testing.T) {
+        // 测试代码...
+    })
+
+    // 生成报告
+    textReport := reporter.GenerateTextReport()
+    t.Logf("Test Report:\n%s", textReport)
+}
+```
+
+## 运行测试
+
+### 运行所有插件测试
+
+```bash
+go test ./plugin/...
+```
+
+### 运行特定测试
+
+```bash
+go test ./plugin/demo/ -v
+```
+
+### 生成测试覆盖率报告
+
+```bash
+go test ./plugin/... -coverprofile=coverage.out
+go tool cover -html=coverage.out -o coverage.html
+```
+
+## 最佳实践
+
+### 1. 测试插件生命周期
+
+确保测试插件的完整生命周期：
+
+```go
+func TestPluginLifecycle(t *testing.T) {
+    manager := test.NewTestPluginManager()
+    plugin := NewMyPlugin()
+
+    // 注册插件
+    manager.RegisterPlugin(plugin)
+
+    // 测试完整生命周期
+    config := map[string]interface{}{
+        "config_key": "config_value",
+    }
+
+    if err := manager.RunPluginLifecycle(t, plugin.Name(), config); err != nil {
+        t.Errorf("Plugin lifecycle failed: %v", err)
+    }
+}
+```
+
+### 2. 测试错误处理
+
+确保测试插件在各种错误情况下的行为：
+
+```go
+func TestPluginErrorHandling(t *testing.T) {
+    // 测试初始化错误
+    pluginWithInitError := test.NewIntegrationTestSuite().
+        CreateMockPlugin("error-plugin", "1.0.0").
+        WithErrorOnInitialize()
+
+    ctx := test.NewTestPluginContext()
+    if err := pluginWithInitError.Initialize(ctx); err == nil {
+        t.Error("Expected initialize error")
+    }
+}
+```
+
+### 3. 测试依赖关系
+
+测试插件的依赖关系处理：
+
+```go
+func TestPluginDependencies(t *testing.T) {
+    plugin := test.NewIntegrationTestSuite().
+        CreateMockPlugin("dep-plugin", "1.0.0").
+        WithDependencies([]string{"dep1", "dep2"})
+
+    deps := plugin.Dependencies()
+    if len(deps) != 2 {
+        t.Errorf("Expected 2 dependencies, got %d", len(deps))
+    }
+}
+```
+
+### 4. 测试上下文操作
+
+测试插件与系统上下文的交互：
+
+```go
+func TestPluginContextOperations(t *testing.T) {
+    operations := []string{
+        "log_info",
+        "set_config",
+        "get_data",
+    }
+
+    plugin := test.NewIntegrationTestSuite().
+        CreateMockPlugin("context-plugin", "1.0.0").
+        WithContextOperations(operations)
+
+    ctx := test.NewTestPluginContext()
+    plugin.Initialize(ctx)
+    plugin.Start()
+
+    // 验证操作结果
+    if !ctx.AssertLogContains(t, "INFO", "Info message") {
+        t.Error("Expected info log")
+    }
+}
+```
+
+## 扩展框架
+
+### 添加新的测试功能
+
+要扩展测试框架，可以：
+
+1. 在`TestPluginContext`中添加新的模拟方法
+2. 在`TestPluginManager`中添加新的测试辅助方法
+3. 在`TestReporter`中添加新的报告功能
+
+### 自定义报告格式
+
+要创建自定义报告格式，可以：
+
+1. 扩展`TestReport`结构
+2. 创建新的报告生成方法
+3. 实现特定的报告输出格式
+

+# 插件卸载机制
+
+本文档详细说明了urlDB插件系统的卸载机制，包括如何安全地卸载插件、清理相关数据和处理依赖关系。
+
+## 插件卸载流程
+
+插件卸载是一个多步骤的过程，确保插件被安全地停止并清理所有相关资源。
+
+### 1. 依赖检查
+
+在卸载插件之前，系统会检查是否有其他插件依赖于该插件：
+
+```go
+dependents := pluginManager.GetDependents(pluginName)
+if len(dependents) > 0 {
+    // 有依赖插件，不能安全卸载（除非使用强制模式）
+}
+```
+
+### 2. 停止插件
+
+如果插件正在运行，系统会先停止它：
+
+```go
+if pluginStatus == types.StatusRunning {
+    err := pluginManager.StopPlugin(pluginName)
+    if err != nil {
+        // 处理停止错误
+    }
+}
+```
+
+### 3. 执行插件清理
+
+调用插件的`Cleanup()`方法，让插件执行自定义清理逻辑：
+
+```go
+err := plugin.Cleanup()
+if err != nil {
+    // 处理清理错误
+}
+```
+
+### 4. 清理数据和配置
+
+系统会自动清理插件的配置和数据：
+
+- 删除插件配置（plugin_config表中的相关记录）
+- 删除插件数据（plugin_data表中的相关记录）
+
+### 5. 清理任务
+
+清理插件注册的任何后台任务。
+
+### 6. 更新依赖图
+
+从依赖图中移除插件信息。
+
+## API 使用示例
+
+### 基本卸载
+
+```go
+// 非强制卸载（推荐）
+err := pluginManager.UninstallPlugin("plugin-name", false)
+if err != nil {
+    log.Printf("卸载失败: %v", err)
+}
+```
+
+### 强制卸载
+
+```go
+// 强制卸载（即使有错误也继续）
+err := pluginManager.UninstallPlugin("plugin-name", true)
+if err != nil {
+    log.Printf("强制卸载完成，但存在错误: %v", err)
+}
+```
+
+### 检查卸载安全性
+
+```go
+// 检查插件是否可以安全卸载
+canUninstall, dependents, err := pluginManager.CanUninstall("plugin-name")
+if err != nil {
+    log.Printf("检查失败: %v", err)
+    return
+}
+
+if !canUninstall {
+    log.Printf("插件不能安全卸载，依赖插件: %v", dependents)
+}
+```
+
+## 插件开发者的责任
+
+插件开发者需要实现以下接口方法以支持卸载：
+
+### Cleanup 方法
+
+```go
+func (p *MyPlugin) Cleanup() error {
+    // 执行清理操作
+    // 例如：关闭外部连接、删除临时文件等
+    return nil
+}
+```
+
+### 最佳实践
+
+1. 在`Cleanup`方法中释放所有外部资源
+2. 不要在`Cleanup`中删除插件核心文件
+3. 处理可能的错误情况，尽可能完成清理工作
+
+## 错误处理
+
+卸载过程中可能出现的错误：
+
+1. 插件不存在
+2. 存在依赖插件
+3. 停止插件失败
+4. 插件清理失败
+5. 数据清理失败
+
+使用非强制模式时，任何错误都会导致卸载失败。使用强制模式时，即使出现错误也会继续执行卸载过程。
+
+## 示例代码
+
+完整的卸载示例：
+
+```go
+// 检查是否可以安全卸载
+canUninstall, dependents, err := pluginManager.CanUninstall("my-plugin")
+if err != nil {
+    log.Printf("检查失败: %v", err)
+    return
+}
+
+if !canUninstall {
+    log.Printf("插件不能安全卸载，依赖插件: %v", dependents)
+    return
+}
+
+// 执行卸载
+err = pluginManager.UninstallPlugin("my-plugin", false)
+if err != nil {
+    log.Printf("卸载失败: %v", err)
+    return
+}
+
+log.Println("插件卸载成功")
+```
+
+## 注意事项
+
+1. 卸载是不可逆操作，执行后插件数据将被永久删除
+2. 建议在卸载前备份重要数据
+3. 强制卸载可能会导致数据不一致，应谨慎使用
+4. 卸载后需要重启相关服务才能重新安装同名插件

+# 插件系统的实现说明
+
+## 1. 插件系统架构概述
+
+插件系统是 urldb 项目中的一个重要组成部分，支持动态加载和管理插件。系统采用模块化设计，支持多种插件类型，包括动态加载的二进制插件和直接嵌入的源代码插件。
+
+### 1.1 核心组件
+
+- **Plugin Manager**：插件管理器，负责插件的注册、初始化、启动、停止和卸载
+- **Plugin Interface**：插件接口，定义了插件必须实现的标准方法
+- **Plugin Loader**：插件加载器，负责从文件系统加载二进制插件
+- **Plugin Registry**：插件注册表，管理插件的元数据和依赖关系
+
+## 2. 插件接口定义
+
+插件系统定义了一个标准的插件接口 `types.Plugin`：
+
+```go
+type Plugin interface {
+    Name() string                    // 插件名称
+    Version() string                 // 插件版本
+    Description() string             // 插件描述
+    Author() string                  // 插件作者
+    Dependencies() []string         // 插件依赖
+    CheckDependencies() map[string]bool // 检查依赖状态
+
+    Initialize(ctx PluginContext) error // 初始化插件
+    Start() error                   // 启动插件
+    Stop() error                    // 停止插件
+    Cleanup() error                 // 清理插件资源
+}
+```
+
+## 3. 插件管理器实现
+
+### 3.1 Manager 结构体
+
+```go
+type Manager struct {
+    plugins        map[string]types.Plugin     // 已注册的插件
+    instances      map[string]*types.PluginInstance // 插件实例
+    registry       *registry.PluginRegistry    // 插件注册表
+    depManager     *DependencyManager          // 依赖管理器
+    securityManager *security.SecurityManager  // 安全管理器
+    monitor        *monitor.PluginMonitor      // 插件监控器
+    configManager  *config.ConfigManager       // 配置管理器
+    pluginLoader   *PluginLoader               // 插件加载器
+    mutex          sync.RWMutex                // 并发控制
+    taskManager    interface{}                 // 任务管理器引用
+    repoManager    *repo.RepositoryManager     // 仓库管理器引用
+    database       *gorm.DB                    // 数据库连接
+}
+```
+
+### 3.2 主要功能
+
+1. **插件注册**：`RegisterPlugin()` 方法用于注册插件
+2. **插件加载**：支持从文件系统加载二进制插件
+3. **依赖管理**：管理插件间的依赖关系
+4. **生命周期管理**：管理插件的初始化、启动、停止和卸载
+5. **安全控制**：基于权限的安全管理
+6. **配置管理**：支持插件配置的管理和验证
+
+### 3.3 依赖管理
+
+插件系统实现了完整的依赖管理功能：
+
+```go
+type DependencyManager struct {
+    manager *Manager
+}
+
+func (dm *DependencyManager) ValidateDependencies() error // 验证依赖
+func (dm *DependencyManager) CheckPluginDependencies(pluginName string) (bool, []string, error) // 检查特定插件依赖
+func (dm *DependencyManager) GetLoadOrder() ([]string, error) // 获取加载顺序
+```
+
+## 4. 插件加载实现
+
+### 4.1 二进制插件加载
+
+二进制插件通过 Go 的 `plugin` 包实现动态加载。`SimplePluginLoader` 负责加载 `.so` 文件：
+
+```go
+type SimplePluginLoader struct {
+    pluginDir string // 插件目录
+}
+
+func (l *SimplePluginLoader) LoadPlugin(filename string) (types.Plugin, error) // 加载单个插件
+func (l *SimplePluginLoader) LoadAllPlugins() ([]types.Plugin, error) // 加载所有插件
+```
+
+### 4.2 反射包装器实现
+
+为了处理不同格式的插件，系统使用反射创建了 `pluginWrapper` 来适配不同的插件实现：
+
+```go
+type pluginWrapper struct {
+    original interface{}
+    value    reflect.Value
+    methods  map[string]reflect.Value
+}
+
+func (l *SimplePluginLoader) createPluginWrapper(plugin interface{}) (types.Plugin, error)
+```
+
+## 5. 安全管理实现
+
+插件系统包含了安全管理功能，控制插件对系统资源的访问权限：
+
+- 权限验证
+- 访问控制
+- 插件隔离
+
+### 5.1 插件上下文
+
+`PluginContext` 为插件提供安全的运行环境和对系统资源的受控访问：
+
+```go
+type PluginContext interface {
+    LogInfo(format string, args ...interface{}) // 记录信息日志
+    LogError(format string, args ...interface{}) // 记录错误日志
+    LogWarn(format string, args ...interface{}) // 记录警告日志
+    SetConfig(key string, value interface{}) error // 设置配置
+    GetConfig(key string) (interface{}, error) // 获取配置
+    SetData(key, value, dataType string) error // 设置数据
+    GetData(key string) (interface{}, error) // 获取数据
+    ScheduleTask(task Task, cronExpression string) error // 调度任务
+}
+```
+
+## 6. 配置管理实现
+
+插件系统支持插件配置的管理和验证：
+
+- 配置模式定义
+- 配置模板管理
+- 配置验证
+
+## 7. 监控和统计
+
+插件系统包含监控功能，可以跟踪插件的执行时间、错误率等指标：
+
+```go
+type PluginMonitor struct {
+    // 监控数据存储
+    // 统计指标计算
+}
+```
+
+## 8. 插件生命周期
+
+插件的完整生命周期包括：
+
+1. **注册**：Plugin → Manager
+2. **初始化**：Initialize() → PluginContext
+3. **启动**：Start() → 后台运行
+4. **运行**：处理任务、响应事件
+5. **停止**：Stop() → 停止功能
+6. **清理**：Cleanup() → 释放资源
+7. **卸载**：从系统中移除
+
+## 9. 示例插件实现
+
+### 9.1 源代码插件示例（FullDemoPlugin）
+
+```go
+type FullDemoPlugin struct {
+    name        string
+    version     string
+    description string
+    author      string
+    context     types.PluginContext
+}
+
+func (p *FullDemoPlugin) Initialize(ctx types.PluginContext) error { ... }
+func (p *FullDemoPlugin) Start() error { ... }
+func (p *FullDemoPlugin) Stop() error { ... }
+func (p *FullDemoPlugin) Cleanup() error { ... }
+```
+
+### 9.2 二进制插件示例（Plugin1）
+
+```go
+type Plugin1 struct{}
+
+func (p *Plugin1) Name() string { return "demo-plugin-1" }
+func (p *Plugin1) Version() string { return "1.0.0" }
+func (p *Plugin1) Description() string { return "这是一个简单的示例插件1" }
+func (p *Plugin1) Initialize(ctx types.PluginContext) error { ... }
+func (p *Plugin1) Start() error { ... }
+func (p *Plugin1) Stop() error { ... }
+func (p *Plugin1) Cleanup() error { ... }
+
+var Plugin = &Plugin1{} // 导出插件实例
+```
+
+## 10. 总结
+
+插件系统采用模块化设计，支持多种插件类型，具有良好的扩展性和安全性。通过标准化的接口和完整的生命周期管理，实现了灵活的插件机制。

+# 插件系统的编译注册使用说明
+
+## 1. 环境准备
+
+### 1.1 系统要求
+- Go 1.23.0 或更高版本
+- 支持 Go plugin 系统的操作系统（Linux, macOS）
+- PostgreSQL 数据库（用于插件数据存储）
+
+### 1.2 项目依赖
+```bash
+go mod tidy
+```
+
+## 2. 创建插件
+
+### 2.1 创建插件目录结构
+```
+my-plugin/
+├── go.mod
+├── plugin.go
+└── main.go (可选，用于构建)
+```
+
+### 2.2 创建 go.mod 文件
+```go
+module github.com/your-org/your-project/plugins/my-plugin
+
+go 1.23.0
+
+replace github.com/ctwj/urldb => ../../../
+
+require github.com/ctwj/urldb v0.0.0
+```
+
+### 2.3 实现插件接口
+
+创建 `plugin.go` 文件：
+
+```go
+package main
+
+import (
+    "github.com/ctwj/urldb/plugin/types"
+)
+
+// MyPlugin 插件结构体
+type MyPlugin struct {
+    name        string
+    version     string
+    description string
+    author      string
+    dependencies []string
+    context     types.PluginContext
+}
+
+// NewMyPlugin 创建新的插件实例
+func NewMyPlugin() *MyPlugin {
+    return &MyPlugin{
+        name:        "my-plugin",
+        version:     "1.0.0",
+        description: "My custom plugin",
+        author:      "Your Name",
+        dependencies: []string{},
+    }
+}
+
+// 实现插件接口方法
+func (p *MyPlugin) Name() string {
+    return p.name
+}
+
+func (p *MyPlugin) Version() string {
+    return p.version
+}
+
+func (p *MyPlugin) Description() string {
+    return p.description
+}
+
+func (p *MyPlugin) Author() string {
+    return p.author
+}
+
+func (p *MyPlugin) Dependencies() []string {
+    return p.dependencies
+}
+
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    result := make(map[string]bool)
+    for _, dep := range p.dependencies {
+        result[dep] = true
+    }
+    return result
+}
+
+func (p *MyPlugin) Initialize(ctx types.PluginContext) error {
+    p.context = ctx
+    ctx.LogInfo("MyPlugin initialized")
+    return nil
+}
+
+func (p *MyPlugin) Start() error {
+    p.context.LogInfo("MyPlugin started")
+    // 启动插件的主要功能
+    return nil
+}
+
+func (p *MyPlugin) Stop() error {
+    p.context.LogInfo("MyPlugin stopped")
+    return nil
+}
+
+func (p *MyPlugin) Cleanup() error {
+    p.context.LogInfo("MyPlugin cleaned up")
+    return nil
+}
+
+// 导出插件实例（用于二进制插件）
+var Plugin = NewMyPlugin()
+```
+
+## 3. 编译插件
+
+### 3.1 编译为二进制插件（.so 文件）
+
+```bash
+# 在插件目录下编译
+go build -buildmode=plugin -o my-plugin.so
+
+# 或者，如果使用不同平台
+# Linux: go build -buildmode=plugin -o my-plugin.so
+# macOS: go build -buildmode=plugin -o my-plugin.so
+# Windows: go build -buildmode=c-shared -o my-plugin.dll (不完全支持)
+```
+
+### 3.2 注意事项
+- Windows 不完全支持 Go plugin 系统
+- 需要确保插件与主程序使用相同版本的依赖
+- 插件必须使用 `buildmode=plugin` 进行编译
+
+## 4. 注册插件
+
+### 4.1 源代码插件注册
+
+将插件作为源代码集成到项目中：
+
+```go
+package main
+
+import (
+    "github.com/ctwj/urldb/plugin"
+    "github.com/your-org/your-project/plugins/my-plugin"
+)
+
+func main() {
+    // 初始化插件系统
+    plugin.InitPluginSystem(taskManager, repoManager)
+
+    // 创建并注册插件
+    myPlugin := my_plugin.NewMyPlugin()  // 注意：下划线是包名的一部分
+    if err := plugin.RegisterPlugin(myPlugin); err != nil {
+        log.Fatal("Failed to register plugin:", err)
+    }
+
+    // 初始化插件
+    plugin.GetManager().InitializePlugin("my-plugin", config)
+
+    // 启动插件
+    plugin.GetManager().StartPlugin("my-plugin")
+}
+```
+
+### 4.2 二进制插件注册
+
+使用插件加载器从文件系统加载二进制插件：
+
+```go
+package main
+
+import (
+    "github.com/ctwj/urldb/plugin"
+    "github.com/ctwj/urldb/plugin/loader"
+)
+
+func main() {
+    // 初始化插件系统
+    plugin.InitPluginSystem(taskManager, repoManager)
+
+    // 创建插件加载器
+    pluginLoader := loader.NewSimplePluginLoader("./plugins")
+
+    // 加载所有插件
+    plugins, err := pluginLoader.LoadAllPlugins()
+    if err != nil {
+        log.Printf("Failed to load plugins: %v", err)
+    } else {
+        // 注册加载的插件
+        for _, p := range plugins {
+            if err := plugin.RegisterPlugin(p); err != nil {
+                log.Printf("Failed to register plugin %s: %v", p.Name(), err)
+            } else {
+                log.Printf("Successfully registered plugin: %s", p.Name())
+            }
+        }
+    }
+}
+```
+
+## 5. 插件配置
+
+### 5.1 创建插件配置
+插件可以接收配置参数：
+
+```go
+config := map[string]interface{}{
+    "interval": 30,     // 30秒间隔
+    "enabled": true,    // 启用插件
+    "custom_param": "value",
+}
+
+// 初始化插件时传入配置
+plugin.GetManager().InitializePlugin("my-plugin", config)
+```
+
+### 5.2 在插件中使用配置
+
+```go
+func (p *MyPlugin) Initialize(ctx types.PluginContext) error {
+    p.context = ctx
+    ctx.LogInfo("MyPlugin initialized")
+
+    // 获取配置
+    if interval, err := ctx.GetConfig("interval"); err == nil {
+        if intVal, ok := interval.(int); ok {
+            p.context.LogInfo("Interval set to: %d seconds", intVal)
+        }
+    }
+
+    return nil
+}
+```
+
+## 6. 插件管理
+
+### 6.1 启动插件
+
+```go
+// 启动单个插件
+if err := plugin.GetManager().StartPlugin("my-plugin"); err != nil {
+    log.Printf("Failed to start plugin: %v", err)
+}
+
+// 启动所有插件
+plugins, _ := plugin.GetManager().GetAllPlugins()
+for _, name := range plugins {
+    plugin.GetManager().StartPlugin(name)
+}
+```
+
+### 6.2 停止插件
+
+```go
+// 停止单个插件
+if err := plugin.GetManager().StopPlugin("my-plugin"); err != nil {
+    log.Printf("Failed to stop plugin: %v", err)
+}
+
+// 停止所有插件
+plugins, _ := plugin.GetManager().GetAllPlugins()
+for _, name := range plugins {
+    plugin.GetManager().StopPlugin(name)
+}
+```
+
+### 6.3 检查插件状态
+
+```go
+// 检查插件是否正在运行
+if plugin.GetManager().IsPluginRunning("my-plugin") {
+    log.Println("Plugin is running")
+} else {
+    log.Println("Plugin is not running")
+}
+
+// 获取所有插件信息
+status := plugin.GetManager().GetAllPluginStatus()
+for name, info := range status {
+    log.Printf("Plugin %s: %s", name, info.Status)
+}
+```
+
+## 7. 插件依赖管理
+
+### 7.1 定义插件依赖
+
+```go
+type MyPlugin struct {
+    dependencies []string
+}
+
+func (p *MyPlugin) Dependencies() []string {
+    return []string{"dependency-plugin-1", "dependency-plugin-2"}
+}
+
+func (p *MyPlugin) CheckDependencies() map[string]bool {
+    result := make(map[string]bool)
+
+    // 检查依赖是否满足
+    for _, dep := range p.dependencies {
+        // 检查依赖插件是否存在且已启动
+        result[dep] = plugin.GetManager().IsPluginRunning(dep)
+    }
+
+    return result
+}
+```
+
+### 7.2 验证依赖
+
+```go
+// 验证所有插件依赖
+if err := plugin.GetManager().ValidateDependencies(); err != nil {
+    log.Printf("Dependency validation failed: %v", err)
+}
+
+// 检查特定插件依赖
+ok, unresolved, err := plugin.GetManager().CheckPluginDependencies("my-plugin")
+if !ok {
+    log.Printf("Unresolved dependencies: %v", unresolved)
+}
+```
+
+## 8. 实际使用示例
+
+### 8.1 完整的插件使用示例
+
+```go
+package main
+
+import (
+    "log"
+    "time"
+
+    "github.com/ctwj/urldb/db"
+    "github.com/ctwj/urldb/db/repo"
+    "github.com/ctwj/urldb/plugin"
+    "github.com/ctwj/urldb/plugin/loader"
+    "github.com/ctwj/urldb/task"
+    "github.com/ctwj/urldb/utils"
+)
+
+func main() {
+    // 初始化日志
+    utils.InitLogger(nil)
+
+    // 初始化数据库
+    if err := db.InitDB(); err != nil {
+        utils.Fatal("Failed to initialize database: %v", err)
+    }
+
+    // 创建管理器
+    repoManager := repo.NewRepositoryManager(db.DB)
+    taskManager := task.NewTaskManager(repoManager)
+
+    // 初始化插件系统
+    plugin.InitPluginSystem(taskManager, repoManager)
+
+    // 加载二进制插件
+    loadBinaryPlugins()
+
+    // 注册源代码插件
+    registerSourcePlugins()
+
+    // 等待运行
+    log.Println("Plugin system ready. Running for 2 minutes...")
+    time.Sleep(2 * time.Minute)
+
+    // 停止插件
+    stopAllPlugins()
+}
+
+func loadBinaryPlugins() {
+    pluginLoader := loader.NewSimplePluginLoader("./plugins")
+
+    if plugins, err := pluginLoader.LoadAllPlugins(); err == nil {
+        for _, p := range plugins {
+            if err := plugin.RegisterPlugin(p); err != nil {
+                log.Printf("Failed to register binary plugin %s: %v", p.Name(), err)
+            }
+        }
+    }
+}
+
+func registerSourcePlugins() {
+    // 注册源代码插件
+    // myPlugin := my_plugin.NewMyPlugin()
+    // plugin.RegisterPlugin(myPlugin)
+}
+
+func stopAllPlugins() {
+    plugins, _ := plugin.GetManager().GetAllPlugins()
+    for _, name := range plugins {
+        if err := plugin.GetManager().StopPlugin(name); err != nil {
+            log.Printf("Failed to stop plugin %s: %v", name, err)
+        }
+    }
+}
+```
+
+## 9. 构建和部署
+
+### 9.1 编译主程序
+
+```bash
+cd examples/plugin_demo
+go build -o plugin_demo main.go
+./plugin_demo
+```
+
+### 9.2 部署插件
+
+1. 将编译好的 `.so` 插件文件复制到插件目录
+2. 确保主程序有读取插件文件的权限
+3. 根据需要配置插件参数
+
+```bash
+# 创建插件目录
+mkdir -p plugins
+
+# 复制插件
+cp my-plugin.so plugins/
+
+# 运行主程序
+./plugin_demo
+```
+
+## 10. 常见问题和解决方案
+
+### 10.1 插件加载失败
+- 检查 `.so` 文件是否与主程序使用相同版本的 Go 编译
+- 确保插件依赖的库与主程序兼容
+- 检查插件文件权限
+
+### 10.2 依赖关系问题

+// Package debug 实现插件调试工具
+//
+// 该包提供了完整的插件调试功能，包括事件收集、追踪、查询和导出。
+//
+// 主要组件:
+//   - Debugger: 主调试器，提供调试功能的统一入口
+//   - EventCollector: 事件收集器，负责收集和存储调试事件
+//   - Tracer: 追踪器，提供函数调用、数据访问等追踪功能
+//   - DebugFileWriter: 文件写入器，将调试信息写入文件
+//
+// 核心特性:
+//   - 实时事件收集和存储
+//   - 函数调用追踪
+//   - 数据访问追踪
+//   - 配置变更追踪
+//   - 任务执行追踪
+//   - 事件查询和过滤
+//   - 多种导出格式支持 (JSON, Text, CSV)
+//   - 统计信息收集
+//   - 会话管理
+//
+// 使用方法:
+//   1. 创建 Debugger 实例并配置
+//   2. 使用 TraceFunction, TraceDataAccess 等方法进行追踪
+//   3. 使用 QueryEvents 查询事件
+//   4. 使用 ExportEvents 导出调试数据
+//
+// 注意事项:
+//   - 调试功能会影响性能，生产环境应谨慎启用
+//   - 大量调试事件可能占用较多内存
+//   - 建议定期清理过期事件

+// Package hotupdate 实现插件热更新功能

+// 该包提供了插件文件监视和自动更新功能，允许在不重启主应用的情况下
+// 更新插件实现。
+//
+// 主要组件:
+//   - PluginWatcher: 监视插件文件变化
+//   - PluginUpdater: 执行插件更新操作
+//
+// 使用方法:
+//   1. 创建 PluginUpdater 实例
+//   2. 调用 StartUpdaterWithWatcher 开始监视
+//   3. 插件文件发生变化时会自动触发更新
+//
+// 注意事项:
+//   - 插件热更新依赖于操作系统的文件监视机制
+//   - 更新过程中插件会短暂停止服务

+// Package market 实现插件市场功能
+//
+// 该包提供了与插件市场交互的功能，包括搜索、安装、更新和卸载插件。
+//
+// 主要组件:
+//   - MarketClient: 与插件市场API交互的客户端
+//   - MarketManager: 管理插件安装和更新的管理器
+//   - PluginInfo: 插件信息结构
+//
+// 使用方法:
+//   1. 创建 MarketClient 连接到插件市场
+//   2. 创建 MarketManager 管理本地插件
+//   3. 使用 Search, Install, Update 等方法管理插件
+//
+// 注意事项:
+//   - 插件市场功能需要网络连接
+//   - 安装插件前应验证校验和
+//   - 需要处理插件依赖关系

+# Plugin Test Framework
+
+This directory contains the plugin test framework for urlDB.
+
+## Components
+
+1. **framework.go** - Basic testing framework with mock implementations
+2. **integration.go** - Integration testing environment and mock plugins
+3. **reporting.go** - Test reporting and result aggregation
+4. **framework_test.go** - Tests for the framework itself
+5. **integration_test.go** - Tests for integration components
+6. **reporting_test.go** - Tests for reporting functionality
+7. **example_test.go** - Example tests demonstrating framework usage
+
+## Usage
+
+See `docs/plugin_testing.md` for detailed documentation on how to use the test framework.
