Subject: [PATCH] refactor(aiCore): restructure test utilities and fix failing
 tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move test utilities from src/__tests__/ to test_utils/
- Fix ModelResolver tests for simplified API (2 params instead of 4)
- Fix generateImage/generateText tests with proper vi.fn() mocks
- Fix ExtensionRegistry.parseProviderId to check variants before aliases
- Add createProvider method overload for dynamic provider IDs
- Update ProviderExtension tests for runtime validation behavior
- Delete outdated tests: initialization.test.ts, extensions.integration.test.ts, executor-resolveModel.test.ts
- Remove 3 skipped tests for removed validate hook
- Add HubProvider.integration.test.ts
- All 359 tests passing, 0 skipped

+### 1.2 核心设计理念
+
+#### 1.2.1 关注点分离 (Separation of Concerns)
+
+- **Service Layer**: 业务逻辑、消息准备、工具调用
+- **AI Provider Layer**: Provider 适配、参数转换、插件构建
+- **Core Package**: 统一 API、Provider 管理、插件执行
+- **AI SDK Layer**: 实际的 LLM API 调用
+
+#### 1.2.2 类型安全优先
+
+- 端到端 TypeScript 类型推断
+- Provider Settings 自动关联
+- 编译时参数验证
+
+#### 1.2.3 可扩展性
+
+- 插件化架构 (AiPlugin)
+- Provider Extension 系统
+- 中间件机制

+### 2.2 关键时序说明
+
+#### 2.2.1 Provider 实例创建（LRU 缓存机制）
+
+```typescript
+// 场景 1: 首次请求 OpenAI (Cache Miss)
+const executor1 = await createExecutor('openai', { apiKey: 'sk-xxx' })
+// → extensionRegistry.createProvider('openai', { apiKey: 'sk-xxx' })
+// → 计算 hash: "abc123"
+// → LRU cache miss
+// → OpenAIExtension.factory() 创建新 provider
+// → 存入 LRU: cache.set("abc123", provider)
+
+// 场景 2: 相同配置的第二次请求 (Cache Hit)
+const executor2 = await createExecutor('openai', { apiKey: 'sk-xxx' })
+// → 计算 hash: "abc123" (相同)
+// → LRU cache hit!
+// → 直接返回缓存的 provider
+// → executor1 和 executor2 共享同一个 provider 实例
+
+// 场景 3: 不同配置 (Cache Miss + 新实例)
+const executor3 = await createExecutor('openai', {
+  apiKey: 'sk-yyy',  // 不同的 key
+  baseURL: 'https://custom.com/v1'
+})
+// → 计算 hash: "def456" (不同)
+// → LRU cache miss
+// → 创建新的独立 provider 实例
+// → 存入 LRU: cache.set("def456", provider2)
+```
+
+#### 2.2.2 插件执行顺序
+
+```typescript
+// 示例：启用 Reasoning + ToolUse + WebSearch
+plugins = [ReasoningPlugin, ToolUsePlugin, WebSearchPlugin]
+
+// 执行顺序：
+1. onRequestStart:    Reasoning → ToolUse → WebSearch
+2. transformParams:   Reasoning → ToolUse → WebSearch (链式)
+3. [AI SDK 调用]
+4. transformResult:   WebSearch → ToolUse → Reasoning (反向)
+5. onRequestEnd:      WebSearch → ToolUse → Reasoning (反向)
+```

+## 3. 核心组件详解
+
+### 3.1 ApiService Layer
+
+#### 文件位置
+`src/renderer/src/services/ApiService.ts`
+
+#### 核心职责
+
+1. **消息准备和转换**
+2. **MCP 工具集成**
+3. **知识库搜索注入**
+4. **API Key 轮换**
+5. **调用 ModernAiProvider**
+
+#### 关键函数详解
+
+##### 3.1.1 `transformMessagesAndFetch()`
+
+**签名**:
+```typescript
+async function transformMessagesAndFetch(
+  request: {
+    messages: Message[]
+    assistant: Assistant
+    blockManager: BlockManager
+    assistantMsgId: string
+    callbacks: StreamProcessorCallbacks
+    topicId?: string
+    options: {
+      signal?: AbortSignal
+      timeout?: number
+      headers?: Record<string, string>
+    }
+  },
+  onChunkReceived: (chunk: Chunk) => void
+): Promise<void>
+```
+
+**执行流程**:
+
+```typescript
+// Step 1: 消息准备
+const { modelMessages, uiMessages } =
+  await ConversationService.prepareMessagesForModel(messages, assistant)
+
+// modelMessages: 转换为 LLM 理解的格式
+// uiMessages: 保留原始 UI 消息（用于某些特殊场景）
+
+// Step 2: 替换 prompt 变量
+assistant.prompt = await replacePromptVariables(
+  assistant.prompt,
+  assistant.model?.name
+)
+// 例如: "{model_name}" → "GPT-4"
+
+// Step 3: 注入知识库搜索
+await injectUserMessageWithKnowledgeSearchPrompt({
+  modelMessages,
+  assistant,
+  assistantMsgId,
+  topicId,
+  blockManager,
+  setCitationBlockId
+})
+
+// Step 4: 发起实际请求
+await fetchChatCompletion({
+  messages: modelMessages,
+  assistant,
+  topicId,
+  requestOptions,
+  uiMessages,
+  onChunkReceived
+})
+```
+
+##### 3.1.2 `fetchChatCompletion()`
+
+**关键代码分析**:
+
+```typescript
+export async function fetchChatCompletion({
+  messages,
+  assistant,
+  requestOptions,
+  onChunkReceived,
+  topicId,
+  uiMessages
+}: FetchChatCompletionParams) {
+
+  // 1. Provider 准备 + API Key 轮换
+  const baseProvider = getProviderByModel(assistant.model || getDefaultModel())
+  const providerWithRotatedKey = {
+    ...baseProvider,
+    apiKey: getRotatedApiKey(baseProvider)  // ✅ 多 key 负载均衡
+  }
+
+  // 2. 创建 AI Provider 实例
+  const AI = new ModernAiProvider(
+    assistant.model || getDefaultModel(),
+    providerWithRotatedKey
+  )
+
+  // 3. 获取 MCP 工具
+  const mcpTools: MCPTool[] = []
+  if (isPromptToolUse(assistant) || isSupportedToolUse(assistant)) {
+    mcpTools.push(...(await fetchMcpTools(assistant)))
+  }
+
+  // 4. 构建 AI SDK 参数
+  const {
+    params: aiSdkParams,
+    modelId,
+    capabilities,
+    webSearchPluginConfig
+  } = await buildStreamTextParams(messages, assistant, provider, {
+    mcpTools,
+    webSearchProviderId: assistant.webSearchProviderId,
+    requestOptions
+  })
+
+  // 5. 构建中间件配置
+  const middlewareConfig: AiSdkMiddlewareConfig = {
+    streamOutput: assistant.settings?.streamOutput ?? true,
+    onChunk: onChunkReceived,
+    model: assistant.model,
+    enableReasoning: capabilities.enableReasoning,
+    isPromptToolUse: usePromptToolUse,
+    isSupportedToolUse: isSupportedToolUse(assistant),
+    isImageGenerationEndpoint: isDedicatedImageGenerationModel(assistant.model),
+    webSearchPluginConfig,
+    enableWebSearch: capabilities.enableWebSearch,
+    enableGenerateImage: capabilities.enableGenerateImage,
+    enableUrlContext: capabilities.enableUrlContext,
+    mcpTools,
+    uiMessages,
+    knowledgeRecognition: assistant.knowledgeRecognition
+  }
+
+  // 6. 调用 AI.completions()
+  await AI.completions(modelId, aiSdkParams, {
+    ...middlewareConfig,
+    assistant,
+    topicId,
+    callType: 'chat',
+    uiMessages
+  })
+}
+```
+
+**API Key 轮换机制**:
+
+```typescript
+function getRotatedApiKey(provider: Provider): string {
+  const keys = provider.apiKey.split(',').map(k => k.trim()).filter(Boolean)
+
+  if (keys.length === 1) return keys[0]
+
+  const keyName = `provider:${provider.id}:last_used_key`
+  const lastUsedKey = window.keyv.get(keyName)
+
+  const currentIndex = keys.indexOf(lastUsedKey)
+  const nextIndex = (currentIndex + 1) % keys.length
+  const nextKey = keys[nextIndex]
+
+  window.keyv.set(keyName, nextKey)
+  return nextKey
+}
+
+// 使用场景：
+// provider.apiKey = "sk-key1,sk-key2,sk-key3"
+// 请求 1 → 使用 sk-key1
+// 请求 2 → 使用 sk-key2
+// 请求 3 → 使用 sk-key3
+// 请求 4 → 使用 sk-key1 (轮回)
+```
+
+### 3.2 ModernAiProvider Layer
+
+#### 文件位置
+`src/renderer/src/aiCore/index_new.ts`
+
+#### 核心职责
+
+1. **Provider 配置转换** (Cherry Provider → AI SDK Config)
+2. **插件构建** (根据 capabilities)
+3. **Trace 集成** (OpenTelemetry)
+4. **调用 RuntimeExecutor**
+5. **流式数据适配** (AI SDK Stream → Cherry Chunk)
+
+#### 构造函数详解
+
+```typescript
+constructor(modelOrProvider: Model | Provider, provider?: Provider) {
+  if (this.isModel(modelOrProvider)) {
+    // 情况 1: new ModernAiProvider(model, provider)
+    this.model = modelOrProvider
+    this.actualProvider = provider
+      ? adaptProvider({ provider, model: modelOrProvider })
+      : getActualProvider(modelOrProvider)
+
+    // 同步或异步创建 config
+    const configOrPromise = providerToAiSdkConfig(
+      this.actualProvider,
+      modelOrProvider
+    )
+    this.config = configOrPromise instanceof Promise
+      ? undefined
+      : configOrPromise
+  } else {
+    // 情况 2: new ModernAiProvider(provider)
+    this.actualProvider = adaptProvider({ provider: modelOrProvider })
+  }
+
+  this.legacyProvider = new LegacyAiProvider(this.actualProvider)
+}
+```
+
+#### completions() 方法详解
+
+```typescript
+public async completions(
+  modelId: string,
+  params: StreamTextParams,
+  providerConfig: ModernAiProviderConfig
+) {
+  // 1. 确保 config 已准备
+  if (!this.config) {
+    this.config = await Promise.resolve(
+      providerToAiSdkConfig(this.actualProvider, this.model!)
+    )
+  }
+
+  // 2. Claude Code OAuth 特殊处理
+  if (this.actualProvider.id === 'anthropic' &&
+      this.actualProvider.authType === 'oauth') {
+    const claudeCodeSystemMessage = buildClaudeCodeSystemModelMessage(
+      params.system
+    )
+    params.system = undefined
+    params.messages = [...claudeCodeSystemMessage, ...(params.messages || [])]
+  }
+
+  // 3. 路由选择
+  if (providerConfig.topicId && getEnableDeveloperMode()) {
+    return await this._completionsForTrace(modelId, params, {
+      ...providerConfig,
+      topicId: providerConfig.topicId
+    })
+  } else {
+    return await this._completionsOrImageGeneration(modelId, params, providerConfig)
+  }
+}
+```
+
+#### modernCompletions() 核心实现
+
+```typescript
+private async modernCompletions(
+  modelId: string,
+  params: StreamTextParams,
+  config: ModernAiProviderConfig
+): Promise<CompletionsResult> {
+
+  // 1. 构建插件
+  const plugins = buildPlugins(config)
+
+  // 2. 创建 RuntimeExecutor
+  const executor = await createExecutor(
+    this.config!.providerId,
+    this.config!.providerSettings,
+    plugins
+  )
+
+  // 3. 流式调用
+  if (config.onChunk) {
+    const accumulate = this.model!.supported_text_delta !== false
+    const adapter = new AiSdkToChunkAdapter(
+      config.onChunk,
+      config.mcpTools,
+      accumulate,
+      config.enableWebSearch
+    )
+
+    const streamResult = await executor.streamText({

+    })
+
+    const finalText = await adapter.processStream(streamResult)
+

+### 4.1 Provider 配置转换
+
+#### providerToAiSdkConfig() 详解
+
+**文件**: `src/renderer/src/aiCore/provider/providerConfig.ts`
+
+```typescript
+export function providerToAiSdkConfig(
+  provider: Provider,
+  model?: Model
+): ProviderConfig | Promise<ProviderConfig> {
+
+  // 1. 根据 provider.id 路由到具体实现
+  switch (provider.id) {
+    case 'openai':
+      return {
+        providerId: 'openai',
+        providerSettings: {
+          apiKey: provider.apiKey,
+          baseURL: provider.apiHost,
+          organization: provider.apiOrganization,
+          headers: provider.apiHeaders
+        }
+      }
+
+    case 'anthropic':

+      // 特殊处理：gateway 需要异步创建
+      return createGatewayConfig(provider, model)

+
+```typescript

+
+  // 3. 使用 AI SDK 的 gateway() 函数
+  const gatewayProvider = gateway({

+      }
+    }
+  })
+
+  return {

+```
+
+### 4.2 Provider Extension 系统
+

+#### 核心设计
+
+```typescript

+      updateAgeOnGet: true    // LRU 行为
+    })
+  }
+
+  // 2. 创建 provider（带缓存）
+  async createProvider(
+    settings?: TSettings,

+
+    // 2.6 存入 LRU 缓存
+    this.instances.set(hash, provider)
+
+    return provider
+  }
+
+  // 3. Hash 计算（保证相同配置得到相同 hash）
+  private computeHash(settings?: TSettings, variantSuffix?: string): string {
+    const baseHash = (() => {
+      if (settings === undefined || settings === null) {
+        return 'default'
+      }
+
+      // 稳定序列化（对象键排序）

+        const pairs = keys.map(key =>
+          `${JSON.stringify(key)}:${stableStringify(obj[key])}`
+        )
+        return `{${pairs.join(',')}}`
+      }
+
+      const serialized = stableStringify(settings)
+
+      // 简单哈希函数
+      let hash = 0
+      for (let i = 0; i < serialized.length; i++) {
+        const char = serialized.charCodeAt(i)
+        hash = (hash << 5) - hash + char
+        hash = hash & hash
+      }
+
+      return `${Math.abs(hash).toString(36)}`
+    })()
+
+    // 附加 variantSuffix
+    return variantSuffix ? `${baseHash}:${variantSuffix}` : baseHash

+          }
+        })
+      }
+    }
+  ],
+
+  // Factory 函数
+  create: async (settings: OpenAIProviderSettings) => {

+
+## 10. 性能优化
+
+### 10.1 Provider 实例缓存（LRU）
+
+**优势**:
+- ✅ 避免重复创建相同配置的 provider
+- ✅ 自动清理最久未使用的实例
+- ✅ 内存可控（max: 10 per extension）
+
+**性能指标**:
+```
+Cache Hit:  <1ms  (直接从 Map 获取)
+Cache Miss: ~50ms (创建新 AI SDK provider)
+```
+
+### 10.2 并行请求优化
+
+```typescript
+// ❌ 串行执行（慢）
+const mcpTools = await fetchMcpTools(assistant)
+const params = await buildStreamTextParams(...)
+const plugins = buildPlugins(config)
+
+// ✅ 并行执行（快）
+const [mcpTools, params, plugins] = await Promise.all([
+  fetchMcpTools(assistant),
+  buildStreamTextParams(...),
+  Promise.resolve(buildPlugins(config))
+])
+```
+
+### 10.3 流式响应优化
+
+```typescript
+// 1. 使用 textStream 而非 fullStream
+for await (const textDelta of streamResult.textStream) {
+  onChunk({ type: ChunkType.TEXT_DELTA, text: textDelta })
+}
+
+// 2. 批量发送 chunks（减少 IPC 开销）
+const chunkBuffer: Chunk[] = []
+for await (const textDelta of streamResult.textStream) {
+  chunkBuffer.push({ type: ChunkType.TEXT_DELTA, text: textDelta })
+
+  if (chunkBuffer.length >= 10) {
+    onChunk({ type: ChunkType.BATCH, chunks: chunkBuffer })
+    chunkBuffer.length = 0
+  }
+}
+```
+
+### 10.4 内存优化
+
+```typescript
+// 1. 及时清理大对象
+async processStream(streamResult: StreamTextResult) {
+  try {
+    for await (const delta of streamResult.textStream) {
+      // 处理 delta
+    }
+  } finally {
+    // 确保流被消费完毕
+    await streamResult.consumeStream()
+  }
+}
+
+// 2. LRU 缓存自动淘汰
+// 当缓存达到 max: 10 时，最久未使用的实例会被自动移除

+## 附录 B: 常见问题
+
+### Q1: 为什么要用 LRU 缓存？
+**A**: 避免为相同配置重复创建 provider，同时自动控制内存（最多 10 个实例/extension）。
+
+### Q2: Plugin 和 Middleware 有什么区别？
+**A**:
+- **Plugin**: Cherry Studio 层面的功能扩展（Reasoning, ToolUse, WebSearch）
+- **Middleware**: AI SDK 层面的请求/响应拦截器
+
+### Q3: 什么时候用 Legacy Provider？
+**A**: 仅在图像生成端点且非 gateway 时使用，因为需要图片编辑等高级功能。
+
+### Q4: 如何添加新的 Provider？
+**A**:
+1. 在 `packages/aiCore/src/core/providers/extensions/` 创建 Extension
+2. 注册到 `coreExtensions` 数组
+3. 在 `providerConfig.ts` 添加配置转换逻辑
