# Error Handling Migration Plan
|
|
|
|
**Project**: Error Handling System Consolidation
|
|
**Phase**: Migration & Implementation Planning
|
|
**Version**: 1.0
|
|
**Date**: 2025-01-13
|
|
**Estimated Duration**: 3-5 days (based on FRAMEWORK-IMPROVEMENT-PROPOSALS.md)
|
|
|
|
---
|
|
|
|
## Executive Summary
|
|
|
|
This document provides a detailed, step-by-step migration plan for consolidating the fragmented error handling system into a unified Exception architecture. The migration follows a **phased approach with backward compatibility**, ensuring zero downtime and gradual rollout.
|
|
|
|
**Migration Strategy**:
|
|
- Incremental implementation (7 phases)
|
|
- Backward compatibility maintained throughout
|
|
- Feature flags for gradual rollout
|
|
- Comprehensive testing at each checkpoint
|
|
- Rollback procedures at every phase
|
|
|
|
**Success Criteria**:
|
|
- Zero production incidents during migration
|
|
- All existing error handling functionality preserved
|
|
- Performance improved (target: <1ms exception creation)
|
|
- Code reduction from 2,006 lines → ~1,200 lines
|
|
- Database consolidation from 3 tables → 2 tables
|

## Phase 1: Core Infrastructure (Day 1, Morning)
|
|
|
|
**Goal**: Establish enhanced FrameworkException and unified ExceptionContext foundation
|
|
|
|
### Tasks
|
|
|
|
#### 1.1 Enhance FrameworkException
|
|
**File**: `src/Framework/Exception/FrameworkException.php`
|
|
|
|
**Changes**:
|
|
```php
|
|
// Add new properties
|
|
protected bool $skipAggregation = false;
|
|
protected bool $skipReporting = false;
|
|
protected bool $reported = false;
|
|
|
|
// Add integration control methods
|
|
public function skipAggregation(): self
|
|
{
|
|
$clone = clone $this;
|
|
$clone->skipAggregation = true;
|
|
return $clone;
|
|
}
|
|
|
|
public function skipReporting(): self

|
}
|
|
|
|
// Add severity mapping

public function getSeverity(): ErrorSeverity
|
|
{
|
|

|
|
#### 1.2 Enhance ExceptionContext
|
|
**File**: `src/Framework/Exception/ExceptionContext.php`

});
|
|
```
|
|
|
|
**Acceptance Criteria**:
|
|
- ✅ All unit tests pass (≥95% coverage for Phase 1 code)
|
|
- ✅ No breaking changes to existing exception usage
|
|
- ✅ Performance: Exception creation <1ms
|
|
|
|
**Estimated Time**: 1 hour testing + fixes
|
|
|
|
### Phase 1 Total Time: **7 hours** (≈1 day)
|
|
|
|
### Rollback Plan Phase 1
|
|
If critical issues found:
|
|
1. Revert FrameworkException.php changes
|
|
2. Revert ExceptionContext.php changes
|
|
3. Revert ErrorCode.php changes
|
|
4. Remove ErrorSeverity.php
|
|
5. Run full test suite to verify rollback
|
|
|

|
|
|
|
## Phase 2: Handler Integration (Day 1, Afternoon)
|
|
|
|
**Goal**: Create integrated ErrorHandler with auto-triggering for aggregation and reporting
|
|
|
|
### Tasks
|
|
|
|
#### 2.1 Create New Module Structure
|
|
**Directory**: `src/Framework/Exception/Handler/`
|
|
|
|
**New Files**:
|
|
- `ErrorHandler.php` - Main handler with auto-integration
|
|
- `ErrorLogger.php` - Unified logging
|
|
- `ResponseFactory.php` - HTTP response generation
|
|
- `ContextBuilder.php` - Automatic context building
|
|
|
|
#### 2.2 Implement ErrorHandler
|
|
**File**: `src/Framework/Exception/Handler/ErrorHandler.php`
|
|
|
|
**Implementation**:

**Acceptance Criteria**:
|
|
- ✅ All integration tests pass
|
|
- ✅ Aggregation triggered correctly (sync and async)
|
|
- ✅ Reporting triggered correctly
|
|
- ✅ Context enrichment working
|
|
- ✅ Generic exceptions converted properly
|
|
- ✅ Performance: Exception handling <5ms (excluding async queue)
|
|
|
|
**Estimated Time**: 2 hours testing + fixes
|
|
|
|
### Phase 2 Total Time: **8.5 hours** (≈1 day)
|
|
|
|
### Rollback Plan Phase 2
|
|
If critical issues found:
|
|
1. Disable ErrorHandler registration (`$handler->register()`)
|
|
2. Revert to old ErrorHandling/ system temporarily
|
|
3. Remove Handler/ directory
|
|
4. Remove queue jobs
|
|
5. Run integration tests to verify old system works
|
|

|
## Phase 3: Aggregation Integration (Day 2, Morning)
|
|
|
|
**Goal**: Move ErrorAggregation under Exception/Aggregation/ and integrate with new handler
|
|
|
|
### Tasks
|
|
|
|
#### 3.1 Move ErrorAggregation Module
|
|
**From**: `src/Framework/ErrorAggregation/`
|
|
**To**: `src/Framework/Exception/Aggregation/`
|
|
|
|
**Files to Move**:
|

- `ErrorAggregator.php` → `src/Framework/Exception/Aggregation/ErrorAggregator.php`
|
|
- `ErrorEvent.php` → `src/Framework/Exception/Aggregation/ErrorEvent.php`
|
|
- `ErrorPattern.php` → `src/Framework/Exception/Aggregation/ErrorPattern.php`
|
|
|
|
**Namespace Changes**:
|
|
```php
|
|
// Old: namespace App\Framework\ErrorAggregation;
|
|
// New: namespace App\Framework\Exception\Aggregation;
|
|
```
|
|
|
|
**Estimated Time**: 1 hour (move + namespace updates + test fixes)

|
|
### Rollback Plan Phase 3
|
|
If critical issues found:
|
|
1. Move ErrorAggregation/ back to original location
|
|
2. Revert namespace changes
|
|
3. Remove backward compatibility adapter
|
|
4. Revert ErrorHandler integration with aggregation
|
|
5. Run aggregation tests to verify rollback

- ✅ Severity-based filtering working
|
|
- ✅ Report storage with new ErrorSeverity enum
|
|
- ✅ Backward compatibility adapter functional
|
|
- ✅ Performance: Report creation <10ms
|
|
|
|
**Estimated Time**: 2 hours testing + fixes
|
|
|
|
### Phase 4 Total Time: **6.5 hours** (≈1 day)
|
|
|
|
### Rollback Plan Phase 4
|
|
If critical issues found:
|
|
1. Move ErrorReporting/ back to original location
|
|
2. Revert namespace changes
|
|
3. Remove backward compatibility adapter
|
|
4. Revert ErrorHandler integration with reporting
|
|
5. Run reporting tests to verify rollback
|

## Phase 5: Boundaries Integration (Day 3, Morning)
|
|
|
|
**Goal**: Move ErrorBoundaries under Exception/Boundaries/ and integrate with FrameworkException
|
|
|
|
### Tasks
|
|
|
|
#### 5.1 Move ErrorBoundaries Module
|
|
**From**: `src/Framework/ErrorBoundaries/`
|
|
**To**: `src/Framework/Exception/Boundaries/`
|
|
|
|
**Files to Move**:
|
|
- `ErrorBoundary.php` → `src/Framework/Exception/Boundaries/ErrorBoundary.php`
|
|
- `BoundaryException.php` → `src/Framework/Exception/Boundaries/BoundaryException.php`
|
|
- All related files (config, events, results)
|
|
|
|
**Namespace Changes**:
|
|
```php
|
|
// Old: namespace App\Framework\ErrorBoundaries;
|
|
// New: namespace App\Framework\Exception\Boundaries;
|
|
```
|
|
|
|
**Estimated Time**: 1 hour
|
|
|
|
#### 5.2 Update BoundaryException to Extend FrameworkException
|
|
**File**: `src/Framework/Exception/Boundaries/BoundaryException.php`
|
|
|
|
**Changes**:
|
|
```php

/**
|
|
* Exception thrown by ErrorBoundary when operation fails
|
|
*
|
|
* Extends FrameworkException to inherit:
|
|
* - ErrorCode categorization
|
|
* - ExceptionContext (domain, request, system)
|
|
* - Automatic aggregation/reporting integration
|
|
* - Retry logic

|
|
### Phase 5 Total Time: **8 hours** (≈1 day)
|
|
|
|
### Rollback Plan Phase 5
|
|
If critical issues found:
|
|
1. Move ErrorBoundaries/ back to original location
|
|
2. Revert BoundaryException to not extend FrameworkException
|
|
3. Revert ErrorBoundary changes
|
|
4. Remove BOUND error codes
|
|
5. Run boundary tests to verify rollback
|

|
|
```
|
|
|
|
**Acceptance Criteria**:

|
|
- ✅ Data from 3 tables merged into 2 tables correctly
|
|
- ✅ Migration down (rollback) works correctly
|
|
- ✅ All data preserved during migration
|
|
- ✅ Indexes created for performance
|
|
- ✅ Query performance maintained or improved
|
|
- ✅ Storage implementations work with new schema
|
|
|
|
**Estimated Time**: 2 hours testing + fixes
|
|
|
|
### Phase 6 Total Time: **7 hours** (≈1 day)
|
|
|
|
### Rollback Plan Phase 6
|
|
If critical migration issues:
|
|
1. Run migration->down() to restore old schema
|
|
2. Verify data integrity with checksums
|
|
3. Revert storage implementation changes
|
|
4. Run full test suite on old schema
|
|
5. Investigate migration issues offline
|
|

|
|
// 1. Exception converted to FrameworkException
|
|
expect($result->exception)->toBeInstanceOf(BoundaryException::class);

|
|
// 3. Severity determined
|
|
expect($result->exception->getSeverity())->toBe(ErrorSeverity::CRITICAL);

### Phase 7 Total Time: **14 hours** (≈2 days)
|
|
|
|
### Rollback Plan Phase 7
|
|
Unlikely to need rollback at this stage, but if issues:
|
|
1. Restore deprecated modules from git history
|
|
2. Revert initializer changes
|
|
3. Keep new Exception/ module but disable auto-registration
|
|
4. Update documentation to mark new system as "experimental"
|

## Appendix
|
|
|
|
### A. Backward Compatibility Period
|
|
|
|
**Duration**: 1 minor version (e.g., v2.1 → v2.2)
|
|
|
|
**Deprecated Namespaces**:
|
|
- `App\Framework\ErrorHandling\` → `App\Framework\Exception\Handler\`
|
|
- `App\Framework\ErrorAggregation\` → `App\Framework\Exception\Aggregation\`
|
|
- `App\Framework\ErrorReporting\` → `App\Framework\Exception\Reporting\`
|
|
- `App\Framework\ErrorBoundaries\` → `App\Framework\Exception\Boundaries\`
|
|
|
|
**Adapter Removal Plan**:
|
|
- v2.1: Adapters active, deprecation warnings
|
|
- v2.2: Adapters removed, hard requirement for migration
|
|
|
|
### B. Troubleshooting Guide
|
|
|
|
**Common Issues**:
|
|
|
|
1. **Exception not triggering aggregation**
|
|
- Check `$exception->shouldSkipAggregation()` flag
|
|
- Verify ErrorHandler `enableAggregation` config
|
|
- Check queue is processing jobs
|
|
|
|
2. **Pattern detection not working**
|
|
- Verify fingerprint generation
|
|
- Check database connection
|
|
- Verify cache is working
|
|
|
|
3. **Performance degradation**
|
|
- Check async processing enabled
|
|
- Verify queue workers running
|
|
- Check database indexes
|
|
|
|
4. **Migration rollback needed**
|
|
- Run `migration->down()`
|
|
- Verify data integrity
|
|
- Check application logs
|
|
|
|
### C. Performance Optimization Tips
|
|
|
|
**Exception Creation**:
|
|
- Use `::simple()` for quick exceptions
|
|
- Avoid excessive context data
|
|
- Defer expensive operations
|
|
|
|
**Aggregation**:
|
|
- Use async processing
|
|
- Batch database inserts
|
|
- Cache frequently accessed patterns
|
|
|
|
**Reporting**:
|
|
- Filter aggressively
|
|
- Use processors sparingly
|
|
- Queue for async
|
|
|
|
**Database**:
|
|
- Use appropriate indexes
|
|
- Partition tables by date
|
|
- Archive old data regularly
