🔍 Conflict Analysis: feature/user-avatar → main

Checking for potential conflicts...

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Merge Analysis:

Status: 🟡 Minor conflicts expected

Files with conflicts (2):

1. src/pages/Profile.jsx
   Conflict Type: Same line modifications
   Your changes: Added avatar upload UI
   Their changes: Refactored component structure
   Resolution complexity: Medium

   Diff:
   <<<<<<< feature/user-avatar
     <AvatarUpload onUpload={handleAvatarChange} />
   =======
     <ProfileHeader user={user} />
   >>>>>>> main

2. src/api/userApi.js
   Conflict Type: Adjacent line changes
   Your changes: Added uploadAvatar function
   Their changes: Modified getUser function
   Resolution complexity: Low
   → Can be auto-merged

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Resolution Strategy:

For src/pages/Profile.jsx:
  Option 1: Keep both changes (recommended)
    - Merge avatar upload with new structure
    - Place AvatarUpload in appropriate location

  Option 2: Accept theirs
    - Use refactored structure
    - Manually add avatar upload later

  Option 3: Accept yours
    - Keep avatar upload
    - Delay refactoring

Recommendation: Option 1 - Merge both changes

Would you like me to:
1. Perform merge and auto-resolve what's possible
2. Show detailed merge plan
3. Wait for you to sync main branch first

手动冲突解决指导​

对于复杂的冲突,Claude Code会提供指导:

帮我解决这个Git冲突
🔧 Conflict Resolution Guide

File: src/components/UserList.jsx
Status: Conflicting changes on same lines

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Understanding the Conflict:

Current branch (feature/search):
  Added search functionality with real-time filtering
  +23 lines, -3 lines

Incoming branch (main):
  Refactored to use TypeScript
  +45 lines, -15 lines

Conflict details:
  Both branches modified the same component structure
  Need to merge search logic with TypeScript types

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Step-by-Step Resolution:

Step 1: Accept TypeScript structure (main)
  ✓ Type definitions are important
  ✓ Keep the new interfaces

Step 2: Add search functionality
  ✓ Port search logic to TypeScript
  ✓ Add proper types for search params

Step 3: Update imports
  ✓ Ensure all imports are correct

Step 4: Test the merged version

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Proposed Resolution:

```typescript
interface UserListProps {
  users: User[];
  onUserSelect: (user: User) => void;
  searchable?: boolean; // NEW from feature branch
}

export function UserList({ users, onUserSelect, searchable = false }: UserListProps) {
  const [searchQuery, setSearchQuery] = useState('');

  // Search logic from feature branch (converted to TypeScript)
  const filteredUsers = useMemo(() => {
    if (!searchable || !searchQuery) return users;

    return users.filter(user =>
      user.name.toLowerCase().includes(searchQuery.toLowerCase())
    );
  }, [users, searchQuery, searchable]);

  return (
    <div className="user-list">
      {searchable && (
        <SearchInput
          value={searchQuery}
          onChange={setSearchQuery}
        />
      )}
      {filteredUsers.map(user => (
        <UserCard
          key={user.id}
          user={user}
          onClick={() => onUserSelect(user)}
        />
      ))}
    </div>
  );
}

This resolution: ✓ Keeps TypeScript types (from main) ✓ Adds search functionality (from feature) ✓ Maintains backward compatibility ✓ Follows project conventions

Apply this resolution? [Y/n] Y

✓ Conflict resolved ✓ File updated ✓ Changes staged

Next: Resolve remaining conflicts or complete merge

## 实用技巧和最佳实践

### 技巧1: 提交前自动检查

设置自动的提交前检查:

设置提交前自动运行测试和lint

🔧 Setting up pre-commit hooks...

Installing Husky... ✓ Configured .husky directory

Creating pre-commit hook...

#!/bin/sh . "$(dirname "$0")/_/husky.sh"

echo "🔍 Running pre-commit checks..."

Run linting

echo "📋 Checking code style..." npm run lint if [ $? -ne 0 ]; then echo "❌ Linting failed. Please fix linting errors." exit 1 fi

Run tests

echo "🧪 Running tests..." npm test -- --passWithNoTests if [ $? -ne 0 ]; then echo "❌ Tests failed. Please fix failing tests." exit 1 fi

Check types

echo "📝 Type checking..." npm run type-check if [ $? -ne 0 ]; then echo "❌ Type errors found. Please fix type errors." exit 1 fi

echo "✅ All checks passed! Proceeding with commit..."

✓ Pre-commit hook installed

Test configuration: 📋 Linting: ESLint with Prettier 🧪 Testing: Jest with coverage 📝 Types: TypeScript strict mode

Now every commit will automatically: ✓ Check code style ✓ Run all tests ✓ Verify types ✓ Prevent broken code from being committed


### 技巧2: 智能提交信息

使用模板生成一致的提交信息:

创建提交信息模板

📝 Creating commit message template...

Created .gitmessage:

type: [subject]

│ │ │

│ │ └─⫸ Summary in imperative mood, no period at end

│ │

│ └─⫸ Commit scope: components|api|docs|tests|build|tools

│

└─⫸ Commit type: feat|fix|docs|style|refactor|test|chore

--- COMMIT MESSAGE START (lines below will be kept) ---

Explain why this change is being made

(optional) Describe what changed

(optional) List any related issue numbers

--- FOOTER START ---

Breaking changes: List any breaking changes here

Deprecated: List any deprecated features

Closes: #issue-number

--- COMMIT MESSAGE END ---

Configured Git to use template: git config commit.template .gitmessage

✓ Template created and configured

Usage: git commit

Git will open editor with template

Fill in the details and save

Example commit:

### 技巧3: 自动化分支命名

建立一致的分支命名规范:

创建功能分支时使用标准命名

🌿 Branch Naming Convention

Establishing branch naming rules...

✓ Created branch validation hook ✓ Documented naming patterns

Branch Types:

  1. feature/ - New features Pattern: feature/[feature-name] Examples: ✓ feature/user-authentication ✓ feature/payment-gateway ✓ feature/dark-mode

  2. bugfix/ - Bug fixes Pattern: bugfix/[bug-description] Examples: ✓ bugfix/login-timeout ✓ bugfix/memory-leak ✓ bugfix/validation-error

  3. hotfix/ - Urgent production fixes Pattern: hotfix/[issue]-[description] Examples: ✓ hotfix/123-crash-on-load ✓ hotfix/456-security-patch

  4. release/ - Release preparation Pattern: release/[version] Examples: ✓ release/v1.2.0 ✓ release/v2.0.0-beta

  5. refactor/ - Code refactoring Pattern: refactor/[component-name] Examples: ✓ refactor/auth-system ✓ refactor/database-layer

Naming Rules: ✓ Use lowercase letters ✓ Use hyphens to separate words ✓ Use issue numbers when applicable ✓ Keep names descriptive but concise ✗ No underscores (use hyphens) ✗ No spaces ✗ No special characters

Example workflow:

我要开发一个新功能:用户消息通知

→ Creates: feature/user-message-notifications

分支信息: Type: feature Name: user-message-notifications Base branch: develop Tracking: origin/feature/user-message-notifications

Checklist for this feature: ☐ Implement notification system ☐ Add real-time updates ☐ Create notification preferences ☐ Write tests ☐ Update docs

Start development? [Y/n]


### 技巧4: 提交历史清理

定期清理提交历史:

清理这个功能分支的提交历史

🧹 Cleaning up commit history...

Current branch: feature/user-dashboard Total commits: 23

Analyzing commits...

Commit types found: ✓ Feature commits: 8 ⚠️ Work-in-progress commits: 5 ⚠️ Fix typo commits: 3 ⚠️ "WIP" commits: 4 ⚠️ "Update" commits: 3

Recommendation: Squash to 3 meaningful commits

Proposed structure:

  1. feat: implement dashboard layout and structure Combines: Initial commits, layout work, basic components

  2. feat: add widget system and data integration Combines: Widget implementation, API integration, data handling

  3. feat: add styling and final polish Combines: CSS updates, responsive design, accessibility fixes

Proceed with interactive rebase? [Y/n] Y

✓ Started interactive rebase ✓ Squashing 23 commits → 3 commits ✓ Rewriting history...

New commit history:

f8g9h0i (HEAD) feat: add styling and final polish e7d8c9b feat: add widget system and data integration a6b5c4d feat: implement dashboard layout and structure

✓ Cleanup complete ✓ 3 clean, semantic commits ⚠️ Force push required to update remote

Force push to update remote? [Y/n] Y

✓ Force push successful ✓ Remote branch updated

Benefits: ✓ Clearer history ✓ Easier to review ✓ Better for code archaeology ✓ Follows best practices


### 技巧5: Git别名配置

设置常用Git命令的别名:

设置常用的Git别名来提高效率

⚡ Setting up Git aliases...

Created useful aliases:

Status and log

git st → git status git lg → git log --graph --oneline --all --decorate git hist → git log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short

Branch operations

git co → git checkout git cob → git checkout -b git br → git branch git brd → git branch -d

Commit operations

git cm → git commit -m git ca → git commit --amend git cane → git commit --amend --no-edit

Diff and merge

git df → git diff git dfs → git diff --staged git mt → git mergetool

Remote operations

git pushu → git push -u origin HEAD git pullr → git pull --rebase

Advanced

git last → git log -1 HEAD git undo → git reset --soft HEAD^ git stash-unstaged → git stash --keep-index git unstage → git reset HEAD

✓ Aliases configured

Examples:

Instead of: git status git checkout -b feature/new-feature git commit -m "Add feature" git push -u origin feature/new-feature

Now use: git st git cob feature/new-feature git cm "Add feature" git pushu

Time saved per command: ~3 seconds Daily usage: ~50 commands Time saved per day: ~2.5 minutes Annual savings: ~10 hours! 🎉

### 场景3: 代码审查助手

**情境:** 审查团队成员的PR,确保代码质量

帮我审查团队成员的Pull Request

👨‍💼 Team Code Review Session

Loading Pull Request: #156 - Add file upload feature

Author: @junior-dev Files: 12 files changed, +543 -89 Time since creation: 2 hours

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

INITIAL ASSESSMENT

Overall Impression: Good effort, needs improvements Code Quality: 6/10 Test Coverage: 4/10 Documentation: 7/10 Security: 5/10

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

DETAILED REVIEW

Category 1: Functionality ✅

✅ GOOD: • File upload component works as expected • Progress bar is accurate • Error handling is present

⚠️ CONCERNS: • No file type validation on client side • Missing file size limit (could upload 1GB+) • No cancellation option for uploads

Suggestions:

// Add validation
const validateFile = (file) => {
  const maxSize = 5 * 1024 * 1024; // 5MB
  const allowedTypes = ['image/jpeg', 'image/png', 'application/pdf'];

  if (file.size > maxSize) {
    throw new Error('File too large. Max 5MB.');
  }

  if (!allowedTypes.includes(file.type)) {
    throw new Error('Invalid file type.');
  }
};

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Category 2: Code Quality 🟡

✅ GOOD: • Clean component structure • Good use of React hooks • Consistent naming

⚠️ ISSUES:

  1. Performance - Large file uploads freeze UI Location: src/components/FileUpload.jsx:45 Issue: Synchronous file reading blocks main thread

    Fix:

// Instead of:
const content = await readFile(file);

// Use:
const content = await readFileChunked(file, onProgress);

  1. Memory Leak - Event listeners not cleaned up Location: src/components/FileUpload.jsx:78 Issue: Missing cleanup in useEffect

    Fix:

useEffect(() => {
  window.addEventListener('resize', handleResize);
  return () => {
    window.removeEventListener('resize', handleResize);
  };
}, []);

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Category 3: Testing 🔴

🔴 CRITICAL: Insufficient test coverage

Current: 23% Target: 80%

Missing tests: ❌ No test for large file upload ❌ No test for invalid file type ❌ No test for upload failure ❌ No test for progress tracking ❌ No test for concurrent uploads

Suggested test cases:

describe('FileUpload', () => {
  it('should reject files larger than 5MB', async () => {
    const largeFile = new File(['x'.repeat(6 * 1024 * 1024)], 'large.jpg');
    await expect(uploadFile(largeFile)).rejects.toThrow('too large');
  });

  it('should reject invalid file types', async () => {
    const invalidFile = new File(['content'], 'test.exe');
    await expect(uploadFile(invalidFile)).rejects.toThrow('Invalid type');
  });

  it('should handle network errors gracefully', async () => {
    // Mock failed upload
    await expect(uploadFile(file)).rejects.toThrow('Upload failed');
  });
});

Recommendation: Add at least 10 more test cases

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Category 4: Security 🔴

🔴 CRITICAL ISSUES:

  1. XSS Vulnerability Location: src/components/FileUpload.jsx:92 Issue: File name rendered without sanitization

    Current:

<div>{file.name}</div>

Fix:

import DOMPurify from 'dompurify';
<div>{DOMPurify.sanitize(file.name)}</div>

  1. No CSRF protection Location: src/api/upload.js Issue: Upload endpoint missing CSRF token

    Fix: Add CSRF token to headers

  2. File path traversal Location: src/api/upload.js:34 Issue: Filename not validated

    Fix:

const safeFilename = path.basename(filename);

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Category 5: Documentation ✅

✅ GOOD: • Component is well documented • Props are explained • Usage examples provided

💡 SUGGESTIONS: • Add error codes documentation • Document API rate limits • Add troubleshooting section

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

REVIEW SUMMARY

Required Changes (Must Fix): 🔴 Fix XSS vulnerability 🔴 Add CSRF protection 🔴 Add file validation

Recommended Changes (Should Fix): 🟡 Fix memory leak 🟡 Add error handling tests 🟡 Improve performance for large files

Nice to Have: 💡 Add upload cancellation 💡 Improve documentation 💡 Add progress bar animation

1. **不要提交调试代码**

❌ console.log('debug'); ❌ debugger; ❌ 注释掉的大段代码


2. **不要在提交信息中包含敏感信息**

❌ "Fixed password: admin123" ❌ "Added API key: sk-1234567890"


3. **不要在主分支直接开发**
- 使用功能分支
- 通过PR合并
- 保持主分支稳定

4. **不要忽视冲突**
- 不要盲目使用" theirs"或"ours"
- 理解冲突的原因
- 与团队沟通解决

5. **不要提交生成的文件**

❌ node_modules/ ❌ build/ ❌ dist/ ❌ .next/ ❌ *.log
