What's New?

Enhanced Error Handling

• Granular error capture and reporting

• Specific handling for authentication failures

• Improved timeout management

• Clear distinction between different error types

• User-friendly error messages

Logging System Upgrade

• Detailed request lifecycle logging

• Structured logging with timing information

• Clear separation of debug and info levels

• Request ID tracking throughout processes

• Performance metric integration

API Communication

• Robust token handling and validation

• Improved polling mechanism

• Better handling of 401/500 error cascades

• Automatic retry logic for transient failures

• Request timeout optimization

Technical Enhancements

Request Lifecycle

• Initial request timeout: 60 seconds

• Poll request timeout: 30 seconds

• Overall operation timeout: 5 minutes

• Exponential backoff: 1-5 seconds

• Request ID tracking throughout

Error Categories

1. Network Errors

   • Connection timeouts

   • Request failures

   • Backend timeouts

2. Processing Errors

   • JSON parsing

   • Response validation

   • State management

Challenges Addressed

Error Clarity

• Previous: Generic error messages and unclear status codes

• Now: Specific error types with detailed information

• Solution: Enhanced error matching and logging

Request Tracking

• Previous: Limited visibility into request lifecycle

• Now: Comprehensive request tracking with timing

• Solution: Added request ID and timestamp logging

Developer Updates

New Environment Variables

# Timeout Configuration
REQUEST_TIMEOUT_INITIAL=60     # Initial request timeout
REQUEST_TIMEOUT_POLL=30        # Poll request timeout
REQUEST_TIMEOUT_OVERALL=300    # Overall operation timeout

# Polling Configuration
POLL_INTERVAL_MIN=1           # Minimum polling interval
POLL_INTERVAL_MAX=5           # Maximum polling interval

Logging Patterns

// Request start
debug!("Entering send_api_request function");
info!("Starting API request process at: {}", start_timestamp);

// Authentication
debug!("Authorization header set successfully");

// Status updates
info!("Initial API response received at: {}. Status: {}", timestamp, status);

// Error handling
error!("Authentication failed - invalid or expired token");
warn!("Backend reported a timeout. Stopping polling.");

Error Handling Pattern

match poll_status {
    StatusCode::OK => handle_success(),
    StatusCode::ACCEPTED => continue_polling(),
    StatusCode::UNAUTHORIZED => handle_auth_error(),
    StatusCode::REQUEST_TIMEOUT => handle_timeout(),
    _ => handle_unexpected_error(),
}

Conclusion

Version 0.3.0 represents a significant step forward in system reliability and observability. The enhanced error handling and logging provide better insights into system operation while improving the overall stability and user experience.
