Robust Error Handling and Retry Mechanisms for ALP Looping

Description

Summary of Work

Project Enhancement: Resilient Error Management

Overview

This pull request introduces a comprehensive error handling and retry strategy system for the ALP Looping project, focusing on improving system reliability, observability, and fault tolerance.

Motivation

Modern distributed systems require sophisticated error management to:

• Gracefully handle transient failures
• Provide detailed error insights
• Support automatic recovery mechanisms
• Maintain system stability under unpredictable conditions

Key Improvements

• Implemented flexible retry strategies with multiple backoff approaches
• Created a sophisticated error reporting system
• Added granular error severity classification
• Supported custom error notification callbacks
• Enhanced logging and traceability

Business Impact

• Reduced system downtime
• Improved debugging capabilities
• More predictable error recovery
• Enhanced observability of system behavior

Changes Made

Error Handling Architecture:

• Introduced TransientErrorRetryHandler for configurable retry mechanisms
• Implemented multiple retry strategies:
  • Constant delay
  • Linear backoff
  • Exponential backoff
• Created ErrorReportingManager with comprehensive error tracking
• Added ErrorSeverity enum for granular error classification

Logging and Notification Improvements:

• Robust log file creation mechanism
• Flexible log file path handling
• Support for custom notification callbacks
• Detailed error reporting with contextual information

Architectural Enhancements:

• Decoupled retry logic from core business logic
• Standardized error reporting approach
• Implemented pluggable error recovery strategies

Tests and Verification

Test Coverage Verification:

• Full test suite for retry strategies
  • Validated constant, linear, and exponential backoff
  • Tested max retry limit enforcement
  • Verified custom callback functionality
• Comprehensive error reporting tests
  • Validated error report structure
  • Tested log file creation
  • Verified notification callback integration
• Error severity and recovery strategy tests
• Maintained 100% test pass rate across all scenarios

Key Test Scenarios Covered:

• Transient error handling
• Retry mechanism behavior
• Error reporting accuracy
• Logging and notification system reliability
