|
### Compliance Issues
|
||||||
|
|
||||||
|
#### High Severity
|
||||||
|
1. **GPL-3.0 Dependencies**
|
||||||
|
- Packages: package1, package2, package3
|
||||||
|
- Issue: GPL-3.0 is incompatible with MIT license
|
||||||
|
- Risk: May require open-sourcing your entire project
|
||||||
|
- Recommendation:
|
||||||
|
- Replace with MIT/Apache licensed alternatives
|
||||||
|
- Or change project license to GPL-3.0
|
||||||
|
|
||||||
|
#### Medium Severity
|
||||||
|
2. **Unknown Licenses**
|
||||||
|
- Packages: mystery-lib, old-package
|
||||||
|
- Issue: Cannot determine license compatibility
|
||||||
|
- Risk: Potential legal exposure
|
||||||
|
- Recommendation:
|
||||||
|
- Contact package maintainers
|
||||||
|
- Review source code for license information
|
||||||
|
- Consider replacing with known alternatives
|
||||||
|
```

```
|
||||||
|
|
||||||
|
### 5. Dependency Size Analysis
|
||||||
|
|
||||||
|
Analyze bundle size impact:
|
||||||
|
|
||||||
|
**Bundle Size Impact**
|
||||||
|
```javascript
|
||||||
|
// Analyze NPM package sizes
|
||||||
|
const analyzeBundleSize = async (dependencies) => {
|
||||||
|
const sizeAnalysis = {
|
||||||
|
totalSize: 0,
|
||||||
|
totalGzipped: 0,
|
||||||
|
packages: [],
|
||||||
|
recommendations: []
|
||||||
|
};
|
||||||
|
|
||||||
|
for (const [packageName, info] of Object.entries(dependencies)) {
|
||||||
|
try {
|
||||||
|
// Fetch package stats
|
||||||
|
const response = await fetch(
|
||||||
|
`https://bundlephobia.com/api/size?package=${packageName}@${info.version}`
|
||||||
|
);
|
||||||
|
const data = await response.json();
|
||||||
|
|
||||||
|
const packageSize = {
|
||||||
|
name: packageName,
|
||||||
|
version: info.version,
|
||||||
|
size: data.size,
|
||||||
|
gzip: data.gzip,
|
||||||
|
dependencyCount: data.dependencyCount,
|
||||||
|
hasJSNext: data.hasJSNext,
|
||||||
|
hasSideEffects: data.hasSideEffects
|
||||||
|
};
|
||||||
|
|
||||||
|
sizeAnalysis.packages.push(packageSize);
|
||||||
|
sizeAnalysis.totalSize += data.size;
|
||||||
|
sizeAnalysis.totalGzipped += data.gzip;
|
||||||
|
|
||||||
|
// Size recommendations
|
||||||
|
if (data.size > 1000000) { // 1MB
|
||||||
|
sizeAnalysis.recommendations.push({
|
||||||
|
package: packageName,
|
||||||
|
issue: 'Large bundle size',
|
||||||
|
size: `${(data.size / 1024 / 1024).toFixed(2)} MB`,
|
||||||
|
suggestion: 'Consider lighter alternatives or lazy loading'
|
||||||
|
});
|
||||||
|
}
|
||||||
|
} catch (error) {
|
||||||
|
console.error(`Failed to analyze ${packageName}:`, error);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// Sort by size
|
||||||
|
sizeAnalysis.packages.sort((a, b) => b.size - a.size);
|
||||||
|
|
||||||
|
// Add top offenders
|
||||||
|
sizeAnalysis.topOffenders = sizeAnalysis.packages.slice(0, 10);
|
||||||
|
|
||||||
|
return sizeAnalysis;
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6. Supply Chain Security
|
||||||
|
|
||||||
|
Check for dependency hijacking and typosquatting:
|
||||||
|
|
||||||
|
**Supply Chain Checks**
|
||||||
|
```python

|
## Requirements
|
||||||
|
$ARGUMENTS
|
||||||
|
|
||||||
|
## Instructions
|
||||||
|
|
||||||
|
### 1. Code Analysis
|
||||||
|
First, analyze the current code for:
|
||||||
|
- **Code Smells**
|
||||||
|
- Long methods/functions (>20 lines)
|
||||||
|
- Large classes (>200 lines)
|
||||||
|
- Duplicate code blocks
|
||||||
|
- Dead code and unused variables
|
||||||
|
- Complex conditionals and nested loops
|
||||||
|
- Magic numbers and hardcoded values
|
||||||
|
- Poor naming conventions
|
||||||
|
- Tight coupling between components
|
||||||
|
- Missing abstractions
|
||||||
|
|
||||||
|
- **SOLID Violations**
|
||||||
|
- Single Responsibility Principle violations
|
||||||
|
- Open/Closed Principle issues
|
||||||
|
- Liskov Substitution problems
|
||||||
|
- Interface Segregation concerns
|
||||||
|
- Dependency Inversion violations
|
||||||
|
|
||||||
|
- **Performance Issues**
|
||||||
|
- Inefficient algorithms (O(n²) or worse)
|
||||||
|
- Unnecessary object creation
|
||||||
|
- Memory leaks potential
|
||||||
|
- Blocking operations
|
||||||
|
- Missing caching opportunities
|
||||||
|
|
||||||
|
### 2. Refactoring Strategy
|
||||||
|
|
||||||
|
Create a prioritized refactoring plan:
|
||||||
|
|
||||||
|
**Immediate Fixes (High Impact, Low Effort)**
|
||||||
|
- Extract magic numbers to constants
|
||||||
|
- Improve variable and function names
|
||||||
|
- Remove dead code
|
||||||
|
- Simplify boolean expressions
|
||||||
|
- Extract duplicate code to functions
|
||||||
|
|
||||||
|
**Method Extraction**
|
||||||
|
```
|
||||||
|
# Before
|
||||||
|
def process_order(order):
|
||||||
|
# 50 lines of validation
|
||||||
|
# 30 lines of calculation
|
||||||
|
# 40 lines of notification
|
||||||
|
|
||||||
|
# After
|
||||||
|
def process_order(order):
|
||||||
|
validate_order(order)
|
||||||
|
total = calculate_order_total(order)
|
||||||
|
send_order_notifications(order, total)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Class Decomposition**
|
||||||
|
- Extract responsibilities to separate classes
|
||||||
|
- Create interfaces for dependencies
|
||||||
|
- Implement dependency injection
|
||||||
|
- Use composition over inheritance
|
||||||
|
|
||||||
|
**Pattern Application**
|
||||||
|
- Factory pattern for object creation
|
||||||
|
- Strategy pattern for algorithm variants
|
||||||
|
- Observer pattern for event handling
|
||||||
|
- Repository pattern for data access
|
||||||
|
- Decorator pattern for extending behavior
|
||||||
|
|
||||||
|
### 3. SOLID Principles in Action
|
||||||
|
|
||||||
|
Provide concrete examples of applying each SOLID principle:
|
||||||
|
|
||||||
|
**Single Responsibility Principle (SRP)**
|
||||||
|
```python
|
||||||
|
# BEFORE: Multiple responsibilities in one class
|
||||||
|
class UserManager:
|
||||||
|
def create_user(self, data):
|
||||||
|
# Validate data
|
||||||
|
# Save to database
|
||||||
|
# Send welcome email
|
||||||
|
# Log activity
|
||||||
|
# Update cache
|
||||||
|
pass
|
||||||
|
|
||||||
|
# AFTER: Each class has one responsibility
|
||||||
|
class UserValidator:
|
||||||
|
def validate(self, data): pass
|
||||||
|
|
||||||
|
class UserRepository:
|
||||||
|
def save(self, user): pass
|
||||||
|
|
||||||
|
class EmailService:
|
||||||
|
def send_welcome_email(self, user): pass
|
||||||
|
|
||||||
|
class UserActivityLogger:
|
||||||
|
def log_creation(self, user): pass
|
||||||
|
|
||||||
|
class UserService:
|
||||||
|
def __init__(self, validator, repository, email_service, logger):
|
||||||
|
self.validator = validator
|
||||||
|
self.repository = repository
|
||||||
|
self.email_service = email_service
|
||||||
|
self.logger = logger
|
||||||
|
|
||||||
|
def create_user(self, data):
|
||||||
|
self.validator.validate(data)
|
||||||
|
user = self.repository.save(data)
|
||||||
|
self.email_service.send_welcome_email(user)
|
||||||
|
self.logger.log_creation(user)
|
||||||
|
return user
|
||||||
|
```
|
||||||
|
|
||||||
|
**Open/Closed Principle (OCP)**
|
||||||
|
```python
|
||||||
|
# BEFORE: Modification required for new discount types
|
||||||
|
class DiscountCalculator:
|
||||||
|
def calculate(self, order, discount_type):
|
||||||
|
if discount_type == "percentage":
|
||||||
|
return order.total * 0.1
|
||||||
|
elif discount_type == "fixed":
|
||||||
|
return 10
|
||||||
|
elif discount_type == "tiered":
|
||||||
|
# More logic
|
||||||
|
pass
|
||||||
|
|
||||||
|
# AFTER: Open for extension, closed for modification
|
||||||
|
from abc import ABC, abstractmethod
|
||||||
|
|
||||||
|
class DiscountStrategy(ABC):
|
||||||
|
@abstractmethod
|
||||||
|
def calculate(self, order): pass
|
||||||
|
|
||||||
|
class PercentageDiscount(DiscountStrategy):
|
||||||
|
def __init__(self, percentage):
|
||||||
|
self.percentage = percentage
|
||||||
|
|
||||||
|
def calculate(self, order):
|
||||||
|
return order.total * self.percentage
|
||||||
|
|
||||||
|
class FixedDiscount(DiscountStrategy):
|

**Liskov Substitution Principle (LSP)**
|
||||||
|
```typescript
|
||||||
|
// BEFORE: Violates LSP - Square changes Rectangle behavior
|
||||||
|
class Rectangle {
|
||||||
|
constructor(protected width: number, protected height: number) {}
|
||||||
|
|
||||||
|
setWidth(width: number) { this.width = width; }
|
||||||
|
setHeight(height: number) { this.height = height; }
|
||||||
|
area(): number { return this.width * this.height; }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Square extends Rectangle {
|
||||||
|
setWidth(width: number) {
|
||||||
|
this.width = width;
|
||||||
|
this.height = width; // Breaks LSP
|
||||||
|
}
|
||||||
|
setHeight(height: number) {
|
||||||
|
this.width = height;
|
||||||
|
this.height = height; // Breaks LSP
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Proper abstraction respects LSP
|
||||||
|
interface Shape {
|
||||||
|
area(): number;
|
||||||
|
}
|
||||||
|
|
||||||
|
class Rectangle implements Shape {
|
||||||
|
constructor(private width: number, private height: number) {}
|
||||||
|
area(): number { return this.width * this.height; }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Square implements Shape {
|
||||||
|
constructor(private side: number) {}
|
||||||
|
area(): number { return this.side * this.side; }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Interface Segregation Principle (ISP)**
|
||||||
|
```java
|
||||||
|
// BEFORE: Fat interface forces unnecessary implementations
|
||||||
|
interface Worker {
|
||||||
|
void work();
|
||||||
|
void eat();
|
||||||
|
void sleep();
|
||||||
|
}
|
||||||
|
|
||||||
|
class Robot implements Worker {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
public void eat() { /* robots don't eat! */ }
|
||||||
|
public void sleep() { /* robots don't sleep! */ }
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Segregated interfaces
|
||||||
|
interface Workable {
|
||||||
|
void work();
|
||||||
|
}
|
||||||
|
|
||||||
|
interface Eatable {
|
||||||
|
void eat();
|
||||||
|
}
|
||||||
|
|
||||||
|
interface Sleepable {
|
||||||
|
void sleep();
|
||||||
|
}
|
||||||
|
|
||||||
|
class Human implements Workable, Eatable, Sleepable {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
public void eat() { /* eat */ }
|
||||||
|
public void sleep() { /* sleep */ }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Robot implements Workable {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Dependency Inversion Principle (DIP)**
|
||||||
|
```go
|
||||||
|
// BEFORE: High-level module depends on low-level module
|
||||||
|
type MySQLDatabase struct{}
|
||||||
|
|
||||||
|
func (db *MySQLDatabase) Save(data string) {}
|
||||||
|
|
||||||
|
type UserService struct {
|
||||||
|
db *MySQLDatabase // Tight coupling
|
||||||
|
}
|
||||||
|
|
||||||
|
func (s *UserService) CreateUser(name string) {
|
||||||
|
s.db.Save(name)
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Both depend on abstraction
|
||||||
|
type Database interface {
|
||||||
|
Save(data string)
|
||||||
|
}
|
||||||
|
|
||||||
|
type MySQLDatabase struct{}
|
||||||
|
func (db *MySQLDatabase) Save(data string) {}
|

|
type PostgresDatabase struct{}
|
||||||
|
func (db *PostgresDatabase) Save(data string) {}
|
||||||
|
|
||||||
|
type UserService struct {
|
||||||
|
db Database // Depends on abstraction
|

|
}
|

func NewUserService(db Database) *UserService {
|
||||||
|
return &UserService{db: db}

|
| Metric | Good | Warning | Critical | Action |
|
||||||
|
|--------|------|---------|----------|--------|
|
||||||
|
| Cyclomatic Complexity | <10 | 10-15 | >15 | Split into smaller methods |
|

|
| Method Lines | <20 | 20-50 | >50 | Extract methods, apply SRP |
|
||||||
|
| Class Lines | <200 | 200-500 | >500 | Decompose into multiple classes |
|
||||||
|
| Test Coverage | >80% | 60-80% | <60% | Add unit tests immediately |
|
||||||
|
| Code Duplication | <3% | 3-5% | >5% | Extract common code |
|
||||||
|
| Comment Ratio | 10-30% | <10% or >50% | N/A | Improve naming or reduce noise |
|
||||||
|
| Dependency Count | <5 | 5-10 | >10 | Apply DIP, use facades |

**Refactoring ROI Analysis**
|
||||||
|
|
||||||
|
```
|
||||||
|
Priority = (Business Value × Technical Debt) / (Effort × Risk)
|
||||||
|
|
||||||
|
Business Value (1-10):
|
||||||
|
- Critical path code: 10
|
||||||
|
- Frequently changed: 8
|
||||||
|
- User-facing features: 7
|
||||||
|
- Internal tools: 5
|
||||||
|
- Legacy unused: 2
|
||||||
|
|
||||||
|
Technical Debt (1-10):
|
||||||
|
- Causes production bugs: 10
|
||||||
|
- Blocks new features: 8
|
||||||
|
- Hard to test: 6
|
||||||
|
- Style issues only: 2
|
||||||
|
|
||||||
|
Effort (hours):
|
||||||
|
- Rename variables: 1-2
|
||||||
|
- Extract methods: 2-4
|
||||||
|
- Refactor class: 4-8
|
||||||
|
- Architecture change: 40+
|
||||||
|
|
||||||
|
Risk (1-10):
|
||||||
|
- No tests, high coupling: 10
|
||||||
|
- Some tests, medium coupling: 5
|
||||||
|
- Full tests, loose coupling: 2
|
||||||
|
```
|
||||||
|
|
||||||
|
**Technical Debt Prioritization Decision Tree**
|
||||||
|
|
||||||
|
```
|
||||||
|
Is it causing production bugs?
|
||||||
|
├─ YES → Priority: CRITICAL (Fix immediately)
|
||||||
|
└─ NO → Is it blocking new features?
|
||||||
|
├─ YES → Priority: HIGH (Schedule this sprint)
|
||||||
|
└─ NO → Is it frequently modified?
|
||||||
|
├─ YES → Priority: MEDIUM (Next quarter)
|
||||||
|
└─ NO → Is code coverage < 60%?
|
||||||
|
├─ YES → Priority: MEDIUM (Add tests)
|
||||||
|
└─ NO → Priority: LOW (Backlog)
|
||||||
|
```

|
||||||
|
|
||||||
|
### 7. Refactored Implementation
|
||||||
|
|
||||||
|
Provide the complete refactored code with:
|
||||||
|
|
||||||
|
**Clean Code Principles**
|
||||||
|
- Meaningful names (searchable, pronounceable, no abbreviations)
|
||||||
|
- Functions do one thing well
|
||||||
|
- No side effects
|
||||||
|
- Consistent abstraction levels
|
||||||
|
- DRY (Don't Repeat Yourself)
|
||||||
|
- YAGNI (You Aren't Gonna Need It)
|
||||||
|
|
||||||
|
**Error Handling**
|
||||||
|
```python
|
||||||
|
# Use specific exceptions
|
||||||
|
class OrderValidationError(Exception):
|
||||||
|
pass
|
||||||
|
|
||||||
|
class InsufficientInventoryError(Exception):
|
||||||
|
pass
|
||||||
|
|
||||||
|
# Fail fast with clear messages
|
||||||
|
def validate_order(order):
|
||||||
|
if not order.items:
|
||||||
|
raise OrderValidationError("Order must contain at least one item")
|
||||||
|
|
||||||
|
for item in order.items:
|
||||||
|
if item.quantity <= 0:
|
||||||
|
raise OrderValidationError(f"Invalid quantity for {item.name}")
|
||||||
|
```
|
||||||
|
|
||||||
|
**Documentation**
|
||||||
|
```python
|
||||||
|
def calculate_discount(order: Order, customer: Customer) -> Decimal:
|
||||||
|
"""
|
||||||
|
Calculate the total discount for an order based on customer tier and order value.
|
||||||
|
|
||||||
|
Args:
|
||||||
|
order: The order to calculate discount for
|
||||||
|
customer: The customer making the order
|
||||||
|
|
||||||
|
Returns:
|
||||||
|
The discount amount as a Decimal
|
||||||
|
|
||||||
|
Raises:
|
||||||
|
ValueError: If order total is negative
|
||||||
|
"""
|
||||||
|
```
|
||||||
|
|
||||||
|
### 8. Testing Strategy
|
||||||
|
|
||||||
|
Generate comprehensive tests for the refactored code:
|
||||||
|
|
||||||
|
**Unit Tests**
|
||||||
|
```python
|
||||||
|
class TestOrderProcessor:
|
||||||
|
def test_validate_order_empty_items(self):
|
||||||
|
order = Order(items=[])
|
||||||
|
with pytest.raises(OrderValidationError):
|
||||||
|
validate_order(order)
|
||||||
|
|
||||||
|
def test_calculate_discount_vip_customer(self):
|
||||||
|
order = create_test_order(total=1000)
|
||||||
|
customer = Customer(tier="VIP")
|
||||||
|
discount = calculate_discount(order, customer)
|
||||||
|
assert discount == Decimal("100.00") # 10% VIP discount
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test Coverage**
|
||||||
|
- All public methods tested
|
||||||
|
- Edge cases covered
|
||||||
|
- Error conditions verified
|
||||||
|
- Performance benchmarks included
|
||||||
|
|
||||||
|
### 9. Before/After Comparison
|
||||||
|
|
||||||
|
Provide clear comparisons showing improvements:
|
||||||
|
|
||||||
|
**Metrics**
|
||||||
|
- Cyclomatic complexity reduction
|
||||||
|
- Lines of code per method
|
||||||
|
- Test coverage increase
|
||||||
|
- Performance improvements
|
||||||
|
|
||||||
|
**Example**
|
||||||
|
```
|
||||||
|
Before:
|
||||||
|
- processData(): 150 lines, complexity: 25
|
||||||
|
- 0% test coverage
|
||||||
|
- 3 responsibilities mixed
|
||||||
|
|
||||||
|
After:
|
||||||
|
- validateInput(): 20 lines, complexity: 4
|
||||||
|
- transformData(): 25 lines, complexity: 5
|
||||||
|
- saveResults(): 15 lines, complexity: 3
|
||||||
|
- 95% test coverage
|
||||||
|
- Clear separation of concerns
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10. Migration Guide
|
||||||
|
|
||||||
|
If breaking changes are introduced:
|
||||||
|
|
||||||
|
**Step-by-Step Migration**
|
||||||
|
1. Install new dependencies
|
||||||
|
2. Update import statements
|
||||||
|
3. Replace deprecated methods
|
||||||
|
4. Run migration scripts
|
||||||
|
5. Execute test suite
|
||||||
|
|
||||||
|
**Backward Compatibility**
|
||||||
|
```python
|
||||||
|
# Temporary adapter for smooth migration
|
||||||
|
class LegacyOrderProcessor:
|
||||||
|
def __init__(self):
|
||||||
|
self.processor = OrderProcessor()
|
||||||
|
|
||||||
|
def process(self, order_data):
|
||||||
|
# Convert legacy format
|
||||||
|
order = Order.from_legacy(order_data)
|
||||||
|
return self.processor.process(order)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 11. Performance Optimizations
|
||||||
|
|
||||||
|
Include specific optimizations:
|
||||||
|
|
||||||
|
**Algorithm Improvements**
|
||||||
|
```python
|
||||||
|
# Before: O(n²)
|
||||||
|
for item in items:
|
||||||
|
for other in items:
|
||||||
|
if item.id == other.id:
|
||||||
|
# process
|
||||||
|
|
||||||
|
# After: O(n)
|
||||||
|
item_map = {item.id: item for item in items}
|
||||||
|
for item_id, item in item_map.items():
|
||||||
|
# process
|
||||||
|
```
|
||||||
|
|
||||||
|
**Caching Strategy**
|
||||||
|
```python
|
||||||
|
from functools import lru_cache
|
||||||
|
|
||||||
|
@lru_cache(maxsize=128)
|
||||||
|
def calculate_expensive_metric(data_id: str) -> float:
|
||||||
|
# Expensive calculation cached
|
||||||
|
return result
|
||||||
|
```
|
||||||
|
|
||||||
|

|
- Quantify: Deployment time, failure rate
|
||||||
|
|
||||||
|
### 2. Impact Assessment
|
||||||
|
|
||||||
|
Calculate the real cost of each debt item:
|
||||||
|
|
||||||
|
**Development Velocity Impact**
|
||||||
|
```
|
||||||
|
Debt Item: Duplicate user validation logic
|
||||||
|
Locations: 5 files
|
||||||
|
Time Impact:
|
||||||
|
- 2 hours per bug fix (must fix in 5 places)
|
||||||
|
- 4 hours per feature change
|
||||||
|
- Monthly impact: ~20 hours
|
||||||
|
Annual Cost: 240 hours × $150/hour = $36,000
|
||||||
|
```
|
||||||
|
|
||||||
|
**Quality Impact**
|
||||||
|
```
|
||||||
|
Debt Item: No integration tests for payment flow
|
||||||
|
Bug Rate: 3 production bugs/month
|
||||||
|
Average Bug Cost:
|
||||||
|
- Investigation: 4 hours
|
||||||
|
- Fix: 2 hours
|
||||||
|
- Testing: 2 hours
|
||||||
|
- Deployment: 1 hour
|
||||||
|
Monthly Cost: 3 bugs × 9 hours × $150 = $4,050
|
||||||
|
Annual Cost: $48,600
|
||||||
|
```
|
||||||
|
|
||||||
|
**Risk Assessment**
|
||||||
|
- **Critical**: Security vulnerabilities, data loss risk
|
||||||
|
- **High**: Performance degradation, frequent outages
|
||||||
|
- **Medium**: Developer frustration, slow feature delivery
|
||||||
|
- **Low**: Code style issues, minor inefficiencies
|
||||||
|
|
||||||
|

|
### 5. Implementation Strategy
|
||||||
|
|
||||||
|
**Incremental Refactoring**
|
||||||
|
```python
|
||||||
|
# Phase 1: Add facade over legacy code
|
||||||
|
class PaymentFacade:
|
||||||
|
def __init__(self):
|
||||||
|
self.legacy_processor = LegacyPaymentProcessor()
|
||||||
|
|
||||||
|
def process_payment(self, order):
|
||||||
|
# New clean interface
|
||||||
|
return self.legacy_processor.doPayment(order.to_legacy())
|
||||||
|
|
||||||
|
# Phase 2: Implement new service alongside
|
||||||
|
class PaymentService:
|
||||||
|
def process_payment(self, order):
|
||||||
|
# Clean implementation
|
||||||
|
pass
|
||||||
|
|
||||||
|
# Phase 3: Gradual migration
|
||||||
|
class PaymentFacade:
|
||||||
|
def __init__(self):
|
||||||
|
self.new_service = PaymentService()
|
||||||
|
self.legacy = LegacyPaymentProcessor()
|
||||||
|
|
||||||
|
def process_payment(self, order):
|
||||||
|
if feature_flag("use_new_payment"):
|
||||||
|
return self.new_service.process_payment(order)
|
||||||
|
return self.legacy.doPayment(order.to_legacy())
|
||||||
|
```
|
||||||
|
|
||||||
|
**Team Allocation**
|
||||||
|
```yaml
|
||||||
|
Debt_Reduction_Team:
|
||||||
|
dedicated_time: "20% sprint capacity"
|
||||||
|
|
||||||
|
roles:
|
||||||
|
- tech_lead: "Architecture decisions"
|
||||||
|
- senior_dev: "Complex refactoring"
|
||||||
|
- dev: "Testing and documentation"
|
||||||
|
|
||||||
|
sprint_goals:
|
||||||
|
- sprint_1: "Quick wins completed"
|
||||||
|
- sprint_2: "God class refactoring started"
|
||||||
|
- sprint_3: "Test coverage >60%"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6. Prevention Strategy
|
||||||
|
|
||||||
|
Implement gates to prevent new debt:
|
||||||
|
|
||||||
|
**Automated Quality Gates**
|
||||||
|
```yaml
|
||||||
|
pre_commit_hooks:
|
||||||
|
- complexity_check: "max 10"
|
||||||
|
- duplication_check: "max 5%"
|
||||||
|
- test_coverage: "min 80% for new code"
|
||||||
|
|
||||||
|
ci_pipeline:
|
||||||
|
- dependency_audit: "no high vulnerabilities"
|
||||||
|
- performance_test: "no regression >10%"
|
||||||
|
- architecture_check: "no new violations"
|
||||||
|
|
||||||
|
code_review:
|
||||||
|
- requires_two_approvals: true
|
||||||
|
- must_include_tests: true
|
||||||
|
- documentation_required: true
|
||||||
|
```
|
||||||
|
|
||||||
|
**Debt Budget**
|
||||||
|
```python
|
||||||
|
debt_budget = {
|
||||||
|
"allowed_monthly_increase": "2%",
|
||||||
|
"mandatory_reduction": "5% per quarter",
|
||||||
|
"tracking": {
|
||||||
|
"complexity": "sonarqube",
|
||||||
|
"dependencies": "dependabot",
|
||||||
|
"coverage": "codecov"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 7. Communication Plan
|
||||||
|
|
||||||
|
**Stakeholder Reports**
|
||||||
|
```markdown
|
||||||
|
## Executive Summary
|
||||||
|
- Current debt score: 890 (High)
|
||||||
|
- Monthly velocity loss: 35%
|
||||||
|
