1k Code Review Pr

OneKey PR Code Review

输出语言: 使用中文输出所有审查报告内容。

This skill provides a structured approach to reviewing PRs in the OneKey monorepo, focusing on practical issues that can break builds, cause runtime errors, or lead to maintenance problems.

Review Scope

• Base branch: x (main branch)
• Use triple-dot diff: git fetch origin && git diff origin/x...HEAD

Relationship with pr-review Skill

This skill complements the existing pr-review skill:

Recommendation: For complex PRs, use both skills for comprehensive coverage.

Review Checklist

1. Accidental File Commits (HIGH PRIORITY)

Check for files that shouldn't be in the repository:

# Check for files in root directory that look suspicious
git diff origin/x...HEAD --name-only | grep -E "^[^/]+$" | grep -v -E "\.(md|json|js|ts|yml|yaml)$"

# Check for common accidental commits
git diff origin/x...HEAD --name-only | grep -E "(\.DS_Store|Thumbs\.db|\.env\.local|node_modules|\.log$)"

Report Format:

## 问题: 意外提交的文件
**文件**: `filename`
**问题描述**: 描述为什么这个文件不应该被提交
**修复方案**:
```bash
git rm filename

优先级: 高

### 2. Build Failure Risks (HIGH PRIORITY)

Check for configurations that reference files which may not exist:

**Pattern 1: extraResources referencing generated files**
```javascript
// electron-builder configs
'extraResources': [
  { 'from': 'path/to/generated/file', 'to': '...' }
]

If the file is generated by a script that may skip execution (e.g., platform-specific tools), the build will fail.

Fix Pattern:

• Create placeholder files when skipping generation
• Add file existence checks in CI

Pattern 2: Scripts with early exit without cleanup

# Bad: exits without creating expected output
if ! command -v tool &> /dev/null; then
    echo "Tool not found"
    exit 0  # Build will fail if expecting output file
fi

# Good: create placeholder before exit
if ! command -v tool &> /dev/null; then
    echo "Tool not found"
    mkdir -p "$OUTPUT_PATH"
    touch "$OUTPUT_PATH/expected-file"  # Placeholder
    exit 0
fi

Report Format:

## 问题: 构建失败风险
**相关文件**:
- config-file.js
- script.sh

**问题描述**:
详细说明为什么构建可能失败

**修复方案**:
```bash
# 具体的代码修复

主要修改点:

1. 修改点1
2. 修改点2

优先级: 高

### 3. Script Accuracy (MEDIUM PRIORITY)

Check for inaccurate comments or misleading error messages:

```bash
# Check error messages and comments in shell scripts
grep -n "echo.*Warning\|echo.*Error\|#.*requires\|#.*only available" apps/*/scripts/*.sh

Common Issues:

• Claiming a tool is "only available on X" when it's available elsewhere
• Incorrect version requirements
• Misleading prerequisite descriptions

Report Format:

## 问题: 脚本注释不准确
**文件**: `path/to/script.sh:LINE`

**问题描述**:
注释说 X，但实际上 Y

**修复方案**:
将第 N 行从：
```bash
echo "原始内容"

改为：

echo "修正后内容"

优先级: 中

### 4. CI Workflow Verification (LOW-MEDIUM PRIORITY)

Check for missing verification steps in CI:

**Pattern: Operations without verification**
```yaml
# Bad: no verification after generation
- name: Generate Assets
  run: bash scripts/generate.sh

# Good: verify generation succeeded
- name: Generate Assets
  run: bash scripts/generate.sh

- name: Verify Assets
  run: bash scripts/verify.sh

Check Points:

1. File generation steps should have verification
2. Platform-specific steps should handle cross-platform CI
3. Critical paths should fail fast with clear errors

Report Format:

## 问题: CI 工作流缺少验证
**相关文件**:
- .github/workflows/workflow.yml

**问题描述**:
CI 在执行某操作后没有验证是否成功

**修复方案**:
```yaml
- name: Verify Step
  run: |
    # verification logic

优先级: 低

### 5. Documentation Consistency (LOW PRIORITY)

Check for PR description matching actual changes:

```bash
# List all changed files
git diff origin/x...HEAD --name-status

# Compare with PR description
gh pr view PRNUM --json body

Check Points:

• All significant file changes mentioned in PR
• iOS/Android changes called out for mobile icon updates
• Breaking changes clearly documented
• Migration steps provided if needed

# Find map/forEach with index that mutates array
git diff origin/x...HEAD | grep -E "\.map\(|\.forEach\(" -A5 | grep -E "splice|shift|pop"

6. React Hooks Safety (HIGH PRIORITY)

Check for hooks-related issues that can cause infinite loops, memory leaks, or race conditions:

Pattern 1: useEffect with missing dependencies

// Bad: eslint-disable hides dependency issues
useEffect(() => {
  doSomething(someValue);  // someValue not in deps
  // eslint-disable-next-line react-hooks/exhaustive-deps
}, []);

// Good: include all dependencies or use refs
useEffect(() => {
  doSomething(someValue);
}, [someValue]);

Pattern 2: Non-functional setState in useCallback

// Bad: uses stale state
const handleClick = useCallback(() => {
  setState({ ...state, updated: true });  // state may be stale
}, [state]);

// Good: functional update
const handleClick = useCallback(() => {
  setState(prev => ({ ...prev, updated: true }));
}, []);

Pattern 3: Missing cleanup in useEffect

// Bad: timer not cleaned up
useEffect(() => {
  const timer = setInterval(() => { ... }, 1000);
  if (condition) return;  // Early return without cleanup!
  return () => clearInterval(timer);
}, []);

// Good: always return cleanup
useEffect(() => {
  if (condition) return () => {};
  const timer = setInterval(() => { ... }, 1000);
  return () => clearInterval(timer);
}, []);

Pattern 4: Async validation without abort

// Bad: no cancellation on unmount
useEffect(() => {
  validateAsync(value).then(setResult);
}, [value]);

// Good: with AbortController
useEffect(() => {
  const controller = new AbortController();
  validateAsync(value, controller.signal).then(setResult);
  return () => controller.abort();
}, [value]);

Report Format:

## 问题: Hooks 安全风险
**文件**: `path/to/component.tsx:LINE`

**问题描述**:
- 风险类型：死循环/内存泄漏/竞态条件/过时闭包
- 具体说明

**修复方案**:
```typescript
// 修复后的代码

优先级: 高

### 7. Concurrent Request Control (HIGH PRIORITY)

Check for code that may overwhelm backend with too many requests:

**Pattern 1: Sequential await in loop (performance issue)**
```typescript
// Bad: 500 addresses = 500 sequential API calls = 50+ seconds
for (const address of addresses) {
  await validateAddress(address);  // O(n) API calls
}

// Good: concurrent with rate limiting
import pLimit from 'p-limit';
const limit = pLimit(10);  // max 10 concurrent
await Promise.all(addresses.map(addr =>
  limit(() => validateAddress(addr))
));

Pattern 2: Missing request deduplication

// Bad: polling may stack up requests
useEffect(() => {
  const interval = setInterval(() => {
    fetchData();  // No guard against overlapping requests
  }, 1000);
  return () => clearInterval(interval);
}, [fetchData]);  // fetchData changes = new interval

// Good: with request guard
const isLoading = useRef(false);
useEffect(() => {
  const interval = setInterval(async () => {
    if (isLoading.current) return;
    isLoading.current = true;
    try { await fetchData(); }
    finally { isLoading.current = false; }
  }, 1000);
  return () => clearInterval(interval);
}, []);

Pattern 3: Unbatched validation

// Bad: validate each item individually
items.forEach(async item => {
  const result = await api.validate(item);
});

// Good: batch API if available
const results = await api.validateBatch(items);

Check Points:

1. Loops with await inside - consider Promise.all with p-limit
2. Polling without request guards
3. Form validation that calls API per field
4. File processing without chunking

Report Format:

## 问题: 大量并发/串行请求
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
| 场景 | 请求数 | 预估耗时 |
|------|--------|----------|
| 100 项 | 100 次 | 10 秒 |
| 500 项 | 500 次 | 50 秒 |

**修复方案**:
```typescript
// 使用并发控制
import pLimit from 'p-limit';
const limit = pLimit(10);
await Promise.all(items.map(i => limit(() => process(i))));

优先级: 高

### 8. Deprecated Dependencies (MEDIUM PRIORITY)

Check for deprecated or renamed packages:

```bash
# Check for deprecated packages in package.json changes
git diff origin/x...HEAD -- '**/package.json' | grep -E '^\+.*"[^"]+": "[^"]+"'

# Verify package status
npm view PACKAGE_NAME deprecated 2>/dev/null

Common Patterns:

• Package renamed (e.g., react-native-document-picker → @react-native-documents/picker)
• Package no longer maintained
• Security vulnerabilities in dependencies

Report Format:

## 问题: 依赖包已废弃
**文件**: `package.json`
**包名**: `deprecated-package`

**问题描述**:
该包已被废弃，官方推荐迁移到新包

**迁移建议**:
```bash
yarn remove deprecated-package
yarn add new-package

API 变更:

// 旧 API
import { old } from 'deprecated-package';

// 新 API
import { new } from 'new-package';

优先级: 中

### 9. Error Handling Patterns (MEDIUM PRIORITY)

Check for proper error handling:

**Pattern 1: Silent failures**
```typescript
// Bad: error swallowed, user gets no feedback
try {
  await submitForm();
} catch (error) {
  console.error(error);  // Only logged, not shown
}

// Good: show error to user
try {
  await submitForm();
} catch (error) {
  Toast.error({ title: error.message });
}

Pattern 2: Empty catch blocks

// Bad: completely silent
try { riskyOperation(); } catch {}

// Good: at least log
try { riskyOperation(); } catch (e) { console.warn(e); }

Pattern 3: Silent early returns

// Bad: function exits without feedback
const handleSubmit = () => {
  if (!data) return;  // User clicks button, nothing happens
  // ...
};

// Good: provide feedback
const handleSubmit = () => {
  if (!data) {
    Toast.warning({ title: 'Please fill required fields' });
    return;
  }
  // ...
};

Report Format:

## 问题: 错误处理不完整
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
错误被静默处理，用户无法得知失败原因

**修复方案**:
```typescript
// 添加用户反馈
Toast.error({ title: error.message });

优先级: 中

### 10. Null/Undefined Safety (HIGH PRIORITY)

Check for missing null/undefined guards that can cause crashes:

**Pattern 1: Optional chaining missing**
```typescript
// Bad: crashes if ref is undefined
const value = ref.current.getValue();

// Good: optional chaining
const value = ref.current?.getValue();

Pattern 2: Array access without bounds check

// Bad: may access undefined
const item = items[index];
item.name;  // TypeError if undefined

// Good: with guard
const item = items[index];
if (!item) return;
item.name;

Pattern 3: Callback without null check

// Bad: callback may fire after unmount
onDomReady(() => {
  webviewRef.current.reload();  // ref may be null
});

// Good: with null check
onDomReady(() => {
  if (!webviewRef.current) return;
  webviewRef.current.reload();
});

Pattern 4: Index shifting after array mutation

// Bad: index becomes invalid after splice
for (let i = 0; i < items.length; i++) {
  if (shouldRemove(items[i])) {
    items.splice(i, 1);  // i now points to wrong item!
  }
}

// Good: iterate backwards or use filter
const filtered = items.filter(item => !shouldRemove(item));

Common Crash Sources (from Sentry):

• TypeError: Cannot read property 'X' of undefined
• nil NSString crash in TurboModule
• EXC_BAD_ACCESS when URI is nil
• RetryableMountingLayerException: Unable to find viewState for tag

Report Format:

## 问题: 空值安全
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
缺少空值检查，可能导致 TypeError 或崩溃

**修复方案**:
```typescript
// 添加可选链或空值检查
if (!value) return;

优先级: 高

### 11. Race Conditions & Cleanup (HIGH PRIORITY)

Check for race conditions in React components, especially with React Native Fabric:

**Pattern 1: State update after unmount**
```typescript
// Bad: may update unmounted component
useEffect(() => {
  fetchData().then(data => {
    setState(data);  // Component may be unmounted
  });
}, []);

// Good: with mount check
useEffect(() => {
  let isMounted = true;
  fetchData().then(data => {
    if (isMounted) setState(data);
  });
  return () => { isMounted = false; };
}, []);

Pattern 2: Dialog close + navigation race

// Bad: Fabric crash during rapid navigation
const handleConfirm = () => {
  dialog.close();
  navigation.push('NextPage');  // Race with dialog unmount
};

// Good: delay navigation
const handleConfirm = async () => {
  dialog.close();
  await new Promise(r => setTimeout(r, 100));  // Allow cleanup
  navigation.push('NextPage');
};

Pattern 3: WebView ref access after cleanup

// Bad: ref may be null during cleanup
useEffect(() => {
  return () => {
    webviewRef.current?.stopLoading();  // May crash
  };
}, []);

// Good: capture ref before cleanup
useEffect(() => {
  const webview = webviewRef.current;
  return () => {
    webview?.stopLoading();  // Uses captured reference
  };
}, []);

Common Fabric Crashes:

• RetryableMountingLayerException - View already unmounted
• SurfaceControl crashes on Android - MIUI/HyperOS specific
• SIGSEGV during navigation cleanup - WebView race condition

Report Format:

## 问题: 竞态条件
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
组件卸载时状态更新/Dialog 关闭与导航竞争

**修复方案**:
```typescript
// 添加 isMounted 检查或延迟

优先级: 高

### 12. Platform-specific Issues (MEDIUM PRIORITY)

Check for platform-specific code that may cause issues:

**Android Common Issues:**
```typescript
// MIUI/HyperOS splash screen crash
// - SurfaceControl error needs defensive handling
// - Add try-catch for splash operations

// Layout re-measurement
// - tabBarHidden changes need layout update
// - Use LayoutAnimation or forceUpdate

// OOM with images
// - Check bitmap memory limits
// - Use resizeMode and memory-efficient loading

iOS Common Issues:

// EXC_BAD_ACCESS with nil strings
// - Always check for nil before NSString operations
// - Use optional binding in native code

// expo-image crashes
// - Validate URI before passing to Image
// - Handle empty/nil URI gracefully:
if (!uri || uri.length === 0) return null;

// Stack overflow in recursive calls
// - Debounce recursive operations
// - Add depth limits

Quick Check Commands:

# Find platform-specific files in diff
git diff origin/x...HEAD --name-only | grep -E "\.(android|ios)\.(ts|tsx)$"

# Check for native module interactions
git diff origin/x...HEAD | grep -E "NativeModules|TurboModule|requireNativeComponent"

Report Format:

## 问题: 平台特定问题
**平台**: Android/iOS
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
[平台] 特有的崩溃或异常行为

**修复方案**:
```typescript
// 平台特定的防御性代码

优先级: 中

### 13. Type Safety for Numeric Operations (MEDIUM PRIORITY)

Check for type coercion issues with BigNumber/decimal operations:

**Pattern 1: Ensure number type before BigNumber**
```typescript
// Bad: decimals might be string from JSON
const amount = new BigNumber(value).shiftedBy(-decimals);

// Good: ensure number type
const amount = new BigNumber(value).shiftedBy(-Number(decimals));

Pattern 2: String vs Number in API responses

// Bad: API might return string or number
const balance = response.balance;  // Could be "100" or 100

// Good: normalize type
const balance = String(response.balance);  // Or Number() if needed

Pattern 3: Division with potential zero

// Bad: division by zero or undefined
const rate = amount / total;

// Good: guard against zero
const rate = total > 0 ? amount / total : 0;

Report Format:

## 问题: 数值类型安全
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
类型强制转换可能导致 NaN 或计算错误

**修复方案**:
```typescript
// 确保类型正确
const value = Number(input);
if (isNaN(value)) throw new Error('Invalid number');

优先级: 中

### 14. Stale Data Management (MEDIUM PRIORITY)

Check for stale data issues when context changes:

**Pattern 1: Clear cache on context switch**
```typescript
// Bad: stale provider list shown when switching
const [providers, setProviders] = useState([]);
useEffect(() => {
  fetchProviders(type).then(setProviders);
}, [type]);

// Good: clear before fetching
useEffect(() => {
  setProviders([]);  // Clear stale data immediately
  fetchProviders(type).then(setProviders);
}, [type]);

Pattern 2: State/callback captured at wrong time

// Bad: callback captured at setup time, becomes stale
useEffect(() => {
  const savedCallback = onUpdate;  // Captured at setup
  const interval = setInterval(() => {
    savedCallback(getData());  // Uses stale callback!
  }, 1000);
  return () => clearInterval(interval);
}, []);  // Missing onUpdate dependency

// Good: use ref for latest callback value
const
onUpdateRef.current = onUpdate;  // Always fresh
useEffect(() => {
  const interval = setInterval(() => {
    onUpdateRef.current(getData());  // Always uses latest
  }, 1000);
  return () => clearInterval(interval);
}, []);

Note on Refs in Cleanup: For DOM/component refs (like webviewRef), you SHOULD capture the ref before cleanup to ensure you're cleaning up the correct resource. See Section 11, Pattern 3 for the correct ref cleanup pattern.

Pattern 3: State derived from props not updating

// Bad: initial state never updates
const [value, setValue] = useState(props.initialValue);

// Good: sync with prop changes
const [value, setValue] = useState(props.initialValue);
useEffect(() => {
  setValue(props.initialValue);
}, [props.initialValue]);

Report Format:

## 问题: 陈旧数据
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
上下文切换时显示旧数据，造成用户困惑

**修复方案**:
```typescript
// 切换时立即清除旧数据
setData(null);
fetchNewData().then(setData);

优先级: 中

### 15. Debounced Async Validation (MEDIUM PRIORITY)

Check for issues with debounced validation that returns promises:

**Pattern 1: Promise never resolves**
```typescript
// Bad: debounced function may not resolve promise
const debouncedValidate = useMemo(() => {
  let timeoutId: NodeJS.Timeout;
  return (value: string) => {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(async () => {
      await validate(value);  // Promise not returned!
    }, 300);
  };
}, []);

// Good: track and resolve promises
const debouncedValidate = useCallback((value: string) => {
  return new Promise<boolean>((resolve) => {
    clearTimeout(timeoutRef.current);
    timeoutRef.current = setTimeout(async () => {
      const result = await validate(value);
      resolve(result);
    }, 300);
  });
}, [validate]);

Pattern 2: Form validation hangs

// Bad: react-hook-form waits forever
rules={{
  validate: (value) => {
    debouncedValidate(value);  // Returns undefined, not promise!
    return true;  // Always passes initially
  }
}}

// Good: return the promise
rules={{
  validate: (value) => debouncedValidate(value)
}}

Pattern 3: Cleanup pending validations

// Bad: validation continues after unmount
useEffect(() => {
  return () => {
    // No cleanup of pending validation
  };
}, []);

// Good: clear pending validation
useEffect(() => {
  return () => {
    if (timeoutRef.current) clearTimeout(timeoutRef.current);
    if (pendingResolve.current) pendingResolve.current(true);
  };
}, []);

Report Format:

## 问题: 防抖验证 Promise 处理
**文件**: `path/to/file.tsx:LINE`

**问题描述**:
防抖验证函数未正确返回 Promise，导致表单验证挂起

**修复方案**:
```typescript
// 确保返回 Promise 并在卸载时清理

优先级: 中

### 16. Security Considerations for Bulk Operations (HIGH PRIORITY)

Check security aspects of features handling multiple items:

**Pattern 1: File upload without size limits**
```typescript
// Bad: no file size check
const handleFile = async (file: File) => {
  const content = await file.text();  // Could be gigabytes
};

// Good: check size first
const MAX_SIZE = 5 * 1024 * 1024; // 5MB
const handleFile = async (file: File) => {
  if (file.size > MAX_SIZE) {
    throw new Error('File too large');
  }
  const content = await file.text();
};

Pattern 2: Hardcoded contract addresses

// Risk: if address is wrong, funds could be lost
const CONTRACT = '0x123...';  // Should verify checksum

// Better: validate address format
import { getAddress } from 'ethers';
const CONTRACT = getAddress('0x123...');  // Throws if invalid

Pattern 3: Missing input validation

// Bad: trusting user input
const amounts = userInput.split(',').map(Number);

// Good: validate each value
const amounts = userInput.split(',').map(v => {
  const num = Number(v.trim());
  if (isNaN(num) || num < 0) throw new Error('Invalid amount');
  return num;
});
