|
||
## 总览

|
||
|
||
## 1. 图片处理无限内存增长 (v2.1.121)
|
||
|
||
**CHANGELOG 描述**：Fixed unbounded memory growth (multi-GB RSS) when processing many images in a session
|
||
|
||
### 实现位置
|
||
|
||
- `src/utils/imageStore.ts` — 核心修复
|
||
- `src/commands/clear/caches.ts` — 缓存清理
|
||
- `src/screens/REPL.tsx` — UI 层释放
|
||
|
||
### 修复方式
|
||
|
||
三层防护机制：
|
||
|
||
1. **LRU 内存缓存**：`storedImagePaths` Map 上限 200 条目（`MAX_STORED_IMAGE_PATHS`），超出自动驱逐最早条目
|
||
2. **磁盘持久化**：图片 base64 数据写入 `~/.claude/image-cache/<sessionId>/`，内存中仅保留路径字符串
|
||
3. **立即释放**：`setPastedContents({})` 在消息提交/命令执行后清空 React state 中的 base64 数据
|
||
|
||
### 关键代码
|
||
|
||
```typescript
|
||
// imageStore.ts:10
|
||
const MAX_STORED_IMAGE_PATHS = 200
|
||
|
||
// imageStore.ts:115-124
|
||
function evictOldestIfAtCap(): void {
|
||
while (storedImagePaths.size >= MAX_STORED_IMAGE_PATHS) {
|
||
const oldest = storedImagePaths.keys().next().value
|
||
if (oldest !== undefined) {
|
||
storedImagePaths.delete(oldest)
|
||
} else {
|
||
break
|
||
}
|
||
}
|
||
}
|
||
|
||
// imageStore.ts:129-167 — 清理旧会话目录
|
||
export async function cleanupOldImageCaches(): Promise<void> { ... }
|
||
```
|
||
|
||
---
|
||
|
||
## 2. /usage 命令泄漏约 2GB (v2.1.121)
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed /usage leaking up to ~2GB of memory on machines with large transcript histories
|
||
|
||
### 实现位置
|
||
|
||
- `src/utils/sessionStoragePortable.ts:716-792` — 核心流式读取
|
||
- `src/utils/attribution.ts` — 调用方
|
||
|
||
### 修复方式
|
||
|
||
1. **分块流式读取**：使用 `TRANSCRIPT_READ_CHUNK_SIZE = 1MB` 固定块大小，通过 `fd.read()` 逐块处理，避免一次性加载整个 transcript
|
||
2. **字节级过滤**：在 fd 层面直接跳过 `attribution-snapshot` 类型的行（占长会话 84% 的字节空间）
|
||
3. **边界截断**：搜索 `compact_boundary` 标记，只保留边界之后的数据
|
||
4. **缓冲区控制**：初始缓冲区限制 `Math.min(fileSize, 8MB)`
|
||
|
||
### 关键代码
|
||
|
||
```typescript
|
||
// sessionStoragePortable.ts:716-792
|
||
export async function readTranscriptForLoad(
|
||
filePath: string,
|
||
fileSize: number,
|
||
): Promise<{
|
||
boundaryStartOffset: number
|
||
postBoundaryBuf: Buffer
|
||
hasPreservedSegment: boolean
|
||
}> {
|
||
const s: LoadState = {
|
||
out: {
|
||
buf: Buffer.allocUnsafe(Math.min(fileSize, 8 * 1024 * 1024)),
|
||
len: 0,
|
||
cap: fileSize + 1,
|
||
},
|
||
// ...
|
||
}
|
||
const chunk = Buffer.allocUnsafe(CHUNK_SIZE)
|
||
const fd = await fsOpen(filePath, 'r')
|
||
try {
|
||
let filePos = 0
|
||
while (filePos < fileSize) {
|
||
const { bytesRead } = await fd.read(chunk, 0, Math.min(CHUNK_SIZE, fileSize - filePos), filePos)
|
||
if (bytesRead === 0) break
|
||
filePos += bytesRead
|
||
// ... 分块处理逻辑
|
||
}
|
||
finalizeOutput(s)
|
||
} finally {
|
||
await fd.close()
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 3. 长时间运行工具进度事件泄漏 (v2.1.121)
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed memory leak when long-running tools fail to emit a clear progress event
|
||
|
||
### 实现位置
|
||
|
||
- `src/screens/REPL.tsx:3054-3114` — progress 消息替换逻辑
|
||
- `src/utils/sessionStorage.ts:186-196` — 临时消息类型定义
|
||
|
||
### 修复方式
|
||
|
||
1. **向后扫描替换**：从只检查最后一条消息改为向后遍历所有 progress 消息，找到匹配的 `parentToolUseID` + `type` 后替换（修复交错消息导致 13k+ 条目堆积）
|
||
2. **全屏模式硬上限**：`MAX_FULLSCREEN_SCROLLBACK = 500`，超出截断
|
||
3. **临时消息识别**：`isEphemeralToolProgress()` 区分 `bash_progress`、`sleep_progress` 等一次性消息与需要保留的 `agent_progress` 等
|
||
|
||
### 关键代码
|
||
|
||
```typescript
|
||
// REPL.tsx:3094-3114
|
||
setMessages(oldMessages => {
|
||
const newData = newMessage.data as Record<string, unknown>;
|
||
// Scan backwards to find the last ephemeral progress with matching
|
||
// parentToolUseID and type.
|
||
for (let i = oldMessages.length - 1; i >= 0; i--) {
|
||
const m = oldMessages[i]!
|
||
if (m.type !== 'progress') break
|
||
const mData = m.data as Record<string, unknown> | undefined
|
||
if (
|
||
m.parentToolUseID === newMessage.parentToolUseID &&
|
||
mData?.type === newData.type
|
||
) {
|
||
const copy = oldMessages.slice();
|
||
copy[i] = newMessage;
|
||
return copy;
|
||
}
|
||
}
|
||
return [...oldMessages, newMessage];
|
||
});
|
||
|
||
// REPL.tsx:3058-3064 — 全屏模式硬上限
|
||
const MAX_FULLSCREEN_SCROLLBACK = 500
|
||
const kept = postBoundary.length > MAX_FULLSCREEN_SCROLLBACK
|
||
? postBoundary.slice(-MAX_FULLSCREEN_SCROLLBACK)
|
||
: postBoundary
|
||
return [...kept, newMessage]
|
||
```
|
||
|
||
---
|
||
|
||
## 4. 空闲重新渲染循环 (v2.1.117)
|
||
|
||
**状态：已确认完整**
|
||
|
||
**CHANGELOG 描述**：Fixed idle re-render loop when background tasks are present, reducing memory growth on Linux
|
||
|
||
### 实现位置
|
||
|
||
- `packages/@ant/ink/src/components/ClockContext.tsx` — 核心时钟管理
|
||
|
||
### 已实现部分
|
||
|
||
`ClockContext` 的 `keepAlive` 订阅者分类机制完整存在：
|
||
|
||
```typescript
|
||
// ClockContext.tsx:11-43
|
||
function createClock(tickIntervalMs: number): Clock {
|
||
const subscribers = new Map<() => void, boolean>()
|
||
let interval: ReturnType<typeof setInterval> | null = null
|
||
|
||
function updateInterval(): void {
|
||
const anyKeepAlive = [...subscribers.values()].some(Boolean)
|
||
if (anyKeepAlive) {
|
||
// 有 keepAlive 订阅者时启动 interval
|
||
interval = setInterval(tick, currentTickIntervalMs)
|
||
} else if (interval) {
|
||
// 无 keepAlive 订阅者时停止 interval
|
||
clearInterval(interval)
|
||
interval = null
|
||
}
|
||
}
|
||
|
||
return {
|
||
subscribe(onChange, keepAlive) {
|
||
subscribers.set(onChange, keepAlive)
|
||
updateInterval()
|
||
return () => {
|
||
subscribers.delete(onChange)
|
||
updateInterval()
|
||
}
|
||
},
|
||
// ...
|
||
}
|
||
}
|
||
```
|
||
|
||
### 不确定部分
|
||
|
||
无法确认 `useAnimationFrame` hook 是否在所有使用时钟的组件中正确传递了 `keepAlive` 参数。反编译代码中调用链可能不完整。
|
||
|
||
---
|
||
|
||
## 5. 虚拟滚动器保留历史消息拷贝 (v2.1.101)
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
|
||
|
||
### 实现位置
|
||
|
||
- `src/components/VirtualMessageList.tsx:276-296`
|
||
|
||
### 修复方式
|
||
|
||
增量式键值数组：使用 `useRef` 保存 keys 数组引用，流式追加而非每次 O(n) 全量重建。
|
||
|
||
```typescript
|
||
// VirtualMessageList.tsx:276-296
|
||
const keysRef = useRef<string[]>([])
|
||
const prevMessagesRef = useRef<typeof messages>(messages)
|
||
const prevItemKeyRef = useRef(itemKey)
|
||
if (
|
||
prevItemKeyRef.current !== itemKey ||
|
||
messages.length < keysRef.current.length ||
|
||
messages[0] !== prevMessagesRef.current[0]
|
||
) {
|
||
// 全量重建（仅在 itemKey 变化、数组缩短等场景）
|
||
keysRef.current = messages.map(m => itemKey(m))
|
||
} else {
|
||
// 增量追加（正常流式场景）
|
||
for (let i = keysRef.current.length; i < messages.length; i++) {
|
||
keysRef.current.push(itemKey(messages[i]!))
|
||
}
|
||
}
|
||
prevMessagesRef.current = messages
|
||
prevItemKeyRef.current = itemKey
|
||
const keys = keysRef.current
|
||
```
|
||
|
||
修复前 27k 消息时每次新消息添加产生 ~1MB 内存分配，修复后降为 O(1) 追加。
|
||
|
||
---
|
||
|
||
## 6. 管道模式超宽行过度分配 (v2.1.110)
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed potential excessive memory allocation when piped (non-TTY) Ink output contains a single very wide line
|
||
|
||
### 实现位置
|
||
|
||
- `packages/@ant/ink/src/core/output.ts:200-207`
|
||
|
||
### 修复方式
|
||
|
||
在 `Output.reset()` 中当字符缓存超过 16384 条目时清空：
|
||
|
||
```typescript
|
||
// output.ts:200-207
|
||
reset(width: number, height: number, screen: Screen): void {
|
||
this.width = width
|
||
this.height = height
|
||
this.screen = screen
|
||
this.operations.length = 0
|
||
resetScreen(screen, width, height)
|
||
if (this.charCache.size > 16384) this.charCache.clear() // 关键修复
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 7. 语言语法按需加载 (v2.1.108)
|
||
|
||
**状态：已修复**
|
||
|
||
**CHANGELOG 描述**：Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
|
||
|
||
### 实现位置
|
||
|
||
- `packages/color-diff-napi/src/index.ts:21-37`
|
||
|
||
### 当前状态
|
||
|
||
延迟加载逻辑**已被移除**，改为顶层静态导入。代码注释说明原因：
|
||
|
||
```typescript
|
||
// color-diff-napi/src/index.ts:21-37
|
||
// Static import — createRequire(import.meta.url) fails in Bun --compile mode
|
||
// because the resolved path points to the internal bunfs binary path where
|
||
// node_modules cannot be found. A top-level import ensures the module is
|
||
// bundled and accessible at runtime.
|
||
import hljs from 'highlight.js' // 顶层静态导入
|
||
|
||
type HLJSApi = typeof hljs
|
||
let cachedHljs: HLJSApi | null = null
|
||
function hljsApi(): HLJSApi {
|
||
if (cachedHljs) return cachedHljs
|
||
const mod = hljs as HLJSApi & { default?: HLJSApi }
|
||
cachedHljs = 'default' in mod && mod.default ? mod.default : mod
|
||
return cachedHljs!
|
||
}
|
||
```
|
||
|
||
**影响**：highlight.js 包含 190+ 语言语法（约 50MB），现在在模块加载时即全部载入内存，无法按需释放。这是为了兼容 Bun `--compile` 模式做的妥协。
|
||
|
||
---
|
||
|
||
## 8. NO_FLICKER 模式流状态泄漏 (v2.1.105)
|
||
|
||
**状态：已修复**
|
||
|
||
**CHANGELOG 描述**：Fixed a NO_FLICKER mode memory leak where API retries left stale streaming state
|
||
|
||
### 实现位置
|
||
|
||
- `src/screens/REPL.tsx:1841-1861` — `resetLoadingState()`
|
||
- `src/screens/REPL.tsx:3568-3578` — finally 块调用
|
||
|
||
### 已实现部分
|
||
|
||
`resetLoadingState()` 在 `onQuery` 的 finally 块中无条件调用，清理 `streamingText`、`streamingToolUses` 等：
|
||
|
||
```typescript
|
||
// REPL.tsx:1841-1861
|
||
const resetLoadingState = useCallback(() => {
|
||
setStreamingText(null);
|
||
setStreamingToolUses([]);
|
||
setSpinnerMessage(null);
|
||
// ...
|
||
}, [pickNewSpinnerTip]);
|
||
|
||
// REPL.tsx:3568-3578 — finally 块
|
||
} finally {
|
||
if (queryGuard.end(thisGeneration)) {
|
||
resetLoadingState(); // 无条件清理
|
||
}
|
||
}
|
||
```
|
||
|
||
### 不确定部分
|
||
|
||
无法确认 `query.ts` 中 `StreamingToolExecutor.discard()` 的逻辑是否完整实现了旧工具结果的释放。
|
||
|
||
---
|
||
|
||
## 9. Remote Control 权限条目保留 (v2.1.98)
|
||
|
||
**状态：已修复**
|
||
|
||
**CHANGELOG 描述**：Fixed a memory leak where Remote Control permission handler entries were retained for the lifetime of the session
|
||
|
||
### 实现位置
|
||
|
||
- `src/hooks/useReplBridge.tsx:466-491` — 处理 + 删除
|
||
- `src/hooks/useReplBridge.tsx:712-717` — 注册 + 清理函数
|
||
|
||
### 已实现部分
|
||
|
||
```typescript
|
||
// useReplBridge.tsx:466-491
|
||
const pendingPermissionHandlers = new Map<string, (response: ...) => void>()
|
||
|
||
function handlePermissionResponse(msg: SDKControlResponse): void {
|
||
const requestId = msg.response?.request_id
|
||
if (!requestId) return
|
||
const handler = pendingPermissionHandlers.get(requestId)
|
||
if (!handler) return
|
||
const parsed = parseBridgePermissionResponse(msg)
|
||
if (!parsed) return
|
||
pendingPermissionHandlers.delete(requestId) // 处理后删除
|
||
handler(parsed)
|
||
}
|
||
|
||
// useReplBridge.tsx:712-717
|
||
onResponse(requestId, handler) {
|
||
pendingPermissionHandlers.set(requestId, handler)
|
||
return () => {
|
||
pendingPermissionHandlers.delete(requestId) // 取消时删除
|
||
}
|
||
}
|
||
```
|
||
|
||
### 不确定部分
|
||
|
||
hook 的 cleanup 函数（组件卸载时的 `replBridgePermissionCallbacks = undefined`）是否完整调用。
|
||
|
||
---
|
||
|
||
## 10. MCP HTTP/SSE 缓冲区累积 (v2.1.97)
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed MCP HTTP/SSE connections accumulating ~50 MB/hr of unreleased buffers when servers reconnect
|
||
|
||
### 实现位置
|
||
|
||
- `src/services/api/claude.ts:1557-1564` — `releaseStreamResources()`
|
||
- `src/cli/transports/SSETransport.ts:419` — `reader.releaseLock()`
|
||
- `@modelcontextprotocol/sdk` (sse.js, streamableHttp.js) — `response.body?.cancel()`
|
||
|
||
### 修复方式
|
||
|
||
1. **主动释放响应体**：`releaseStreamResources()` 清理 stream 和 response
|
||
|
||
```typescript
|
||
// claude.ts:1553-1564
|
||
// Release all stream resources to prevent native memory leaks.
|
||
// The Response object holds native TLS/socket buffers that live outside the
|
||
// V8 heap (observed on the Node.js/npm path; see GH #32920), so we must
|
||
// explicitly cancel and release it regardless of how the generator exits.
|
||
function releaseStreamResources(): void {
|
||
cleanupStream(stream)
|
||
stream = undefined
|
||
if (streamResponse) {
|
||
streamResponse.body?.cancel().catch(() => {})
|
||
streamResponse = undefined
|
||
}
|
||
}
|
||
```
|
||
|
||
2. **SSE 读取器释放**：
|
||
|
||
```typescript
|
||
// SSETransport.ts:418-419
|
||
} finally {
|
||
reader.releaseLock()
|
||
}
|
||
```
|
||
|
||
3. **MCP SDK 层面**：在所有 HTTP 路径（成功/失败/重连）调用 `response.body?.cancel()`
|
||
|
||
---
|
||
|
||
## 11. LRU 缓存键保留大 JSON (v2.1.89)
|
||
|
||
**状态：已确认完整实现**
|
||
|
||
|
||
**CHANGELOG 描述**：Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
|
||
|
||
### 实现位置
|
||
|
||
- `src/utils/fileStateCache.ts:37-48` — 大小计算修复
|
||
- `src/utils/queryHelpers.ts:48-54` — 类型强制转换
|
||
|
||
### 修复方式
|
||
|
||
1. **正确计算缓存大小**：处理 `content` 为嵌套对象的情况
|
||
|
||
```typescript
|
||
// fileStateCache.ts:37-48
|
||
sizeCalculation: value => {
|
||
const c = value.content
|
||
const s =
|
||
typeof c === 'string'
|
||
? c
|
||
: c === null || c === undefined
|
||
? ''
|
||
: typeof c === 'object'
|
||
? JSON.stringify(c)
|
||
: String(c)
|
||
return Math.max(1, Buffer.byteLength(s, 'utf8'))
|
||
}
|
||
```
|
||
|
||
2. **强制类型转换**：确保 Write 工具 content 始终为字符串
|
||
|
||
```typescript
|
||
// queryHelpers.ts:48-54
|
||
function coerceToolContentToString(value: unknown): string {
|
||
if (typeof value === 'string') return value
|
||
if (value === null || value === undefined) return ''
|
||
if (typeof value === 'object') return JSON.stringify(value)
|
||
return String(value)
|
||
}
|
||
```
|
||
|
||

|
||
|
||
## 12. QueryEngine.mutableMessages 不收缩
|
||
|
||
**状态：已修复**
|
||
|

**代码注释描述**：`markers persist and re-trigger on every turn, and mutableMessages never shrinks (memory leak in long SDK sessions)`（`src/QueryEngine.ts:929-930`）
|
||
|
||
### 实现位置
|
||
|
||
- `src/services/compact/snipCompact.ts` — **存根文件**
|
||
- `src/QueryEngine.ts:925-962` — 消息处理逻辑
|
||
|
||
### 问题详情
|
||
|
||
`mutableMessages` 数组只增不减，每轮对话 push 多条消息（assistant、progress、user、attachment 等）。清理依赖两条路径：
|
||
|
||
**路径 1：API 返回 compact_boundary**（已实现）
|
||
|
||
```typescript
|
||
// QueryEngine.ts:946-962
|
||
if (msg.subtype === 'compact_boundary' && msg.compactMetadata) {
|
||
const mutableBoundaryIdx = this.mutableMessages.length - 1
|
||
if (mutableBoundaryIdx > 0) {
|
||
this.mutableMessages.splice(0, mutableBoundaryIdx) // 清理旧消息
|
||
}
|
||
}
|
||
```
|
||
|
||
**路径 2：本地 snip 压缩**（存根 — 永不执行）
|
||
|
||
```typescript
|
||
// snipCompact.ts — 完整文件
|
||
// Auto-generated stub — replace with real implementation
|
||
export {};
|
||
import type { Message } from 'src/types/message';
|
||
|
||
export const isSnipMarkerMessage: (message: Message) => boolean = () => false;
|
||
export const snipCompactIfNeeded: (
|
||
messages: Message[],
|
||
options?: { force?: boolean },
|
||
) => { messages: Message[]; executed: boolean; tokensFreed: number; boundaryMessage?: Message } = (messages) => ({
|
||
messages,
|
||
executed: false, // 永远 false — 清理从不执行
|
||
tokensFreed: 0,
|
||
});
|
||
export const isSnipRuntimeEnabled: () => boolean = () => false;
|
||
export const shouldNudgeForSnips: (messages: Message[]) => boolean = () => false;
|
||
export const SNIP_NUDGE_TEXT: string = '';
|
||
```
|
||
|
||
`snipReplay` 回调依赖 `HISTORY_SNIP` feature flag，且调用的 `snipCompactIfNeeded` 永远返回 `executed: false`。
|
||
|
||
```typescript
|
||
// QueryEngine.ts:933-942
|
||
const snipResult = this.config.snipReplay?.(msg, this.mutableMessages)
|
||
if (snipResult !== undefined) {
|
||
if (snipResult.executed) { // 永远是 false
|
||
this.mutableMessages.length = 0
|
||
this.mutableMessages.push(...snipResult.messages)
|
||
}
|
||
break
|
||
}
|
||
```
|
||
|
||
### 风险评估
|
||
|
||
- 在长时间 SDK 会话中，如果 API 不频繁返回 `compact_boundary`，`mutableMessages` 会持续增长
|
||
- 每条消息可能包含大量内容（工具输出、文件内容等），长时间运行可能导致 GB 级内存占用
|
||
- 这是当前代码库中**最明确的未实现内存泄漏点**

| #7 语言注册 | `packages/color-diff-napi/src/__tests__/language-registration.test.ts` | 7 |
|
||
| **总计** | **6 个测试文件** | **72** |
|

```
|

|
||
### 需要关注的优先级
|
||
|
||
1. ~~**P0 — `snipCompact.ts` 存根**~~ **已修复**
|
||
2. **P1 — 语法按需加载回退**：highlight.js 190+ 语法常驻内存（~5-15MB），无释放时机
|
||
3. ~~**P2 — NO_FLICKER 流状态**~~ **已修复**
|
||
4. **P2 — 空闲渲染循环**：框架存在但反编译代码中 keepAlive 集成完整性不确定
