Webhook System Enhancements and Test Coverage

Overview

This PR introduces significant improvements to the webhook system, focusing on reliability, performance, and maintainability. The changes include enhanced branch-based filtering, improved retry logic, connection pooling, and comprehensive test coverage.

Key Changes

1. Branch-Based Webhook Filtering

• Added support for filtering webhooks by branch_id in both payload and events
• Implemented default branch_id (99) when none specified
• Added handling for multiple events targeting different branches
• Ensured proper deduplication of branch events

2. Enhanced Retry Logic

• Implemented exponential backoff for retries
• Added support for retrying on server errors (500, 502, 503, 504)
• Improved timeout handling
• Added proper error logging and status tracking

3. Connection Pooling

• Implemented connection pooling for better performance
• Added limits configuration for max connections and keepalive
• Optimized connection reuse across multiple requests

4. Error Handling and Logging

• Enhanced error handling for various failure scenarios
• Improved logging of webhook attempts and failures
• Added proper cleanup of failed webhook logs
• Implemented better error propagation

5. Webhook Log Cleanup

• Added automated cleanup of logs older than 15 days
• Implemented efficient batch deletion for large log sets
• Added proper handling of cleanup edge cases

Test Coverage

New Test Cases Added

1. Branch Filtering Tests

   • test_webhook_branch_filtering: Basic branch filtering
   • test_webhook_mixed_branch_events: Complex branch scenarios
   • Tests for default branch behavior

2. Retry Logic Tests

   • test_webhook_exponential_backoff: Retry timing and behavior
   • test_webhook_retry_edge_cases: Various retry scenarios
   • Tests for different error types and recovery

3. Connection Pooling Tests

   • test_webhook_connection_pooling: Basic pooling functionality
   • test_webhook_concurrent_requests: Performance under load
   • Tests for connection reuse and limits

4. Error Handling Tests

   • test_webhook_error_handling: Various error scenarios
   • test_webhook_invalid_payload_handling: Invalid input cases
   • test_webhook_headers_validation: Header validation

5. Log Cleanup Tests

   • test_webhook_log_cleanup: Basic cleanup functionality
   • test_webhook_log_cleanup_edge_cases: Complex cleanup scenarios
   • Tests for large log sets and multiple endpoints

Test Coverage Improvements

• Added comprehensive edge case coverage
• Improved error scenario testing
• Added performance testing
• Enhanced validation testing
• Added concurrent request testing

Performance Improvements

• Reduced connection overhead through pooling
• Optimized retry logic with exponential backoff
• Improved log cleanup efficiency
• Better resource utilization

Security Considerations

• Proper validation of webhook URLs
• Secure handling of headers
• Safe cleanup of sensitive data
• Proper error handling to prevent information leakage

Migration Notes

• No database schema changes required
• Backward compatible with existing webhook endpoints
• No changes to webhook payload format
• Existing logs will be cleaned up according to new retention policy

Testing Instructions

1. Run the full test suite: make test
2. Verify webhook delivery to different branches
3. Test error scenarios and retry behavior
4. Monitor log cleanup functionality
5. Verify connection pooling under load

Future Considerations

• Potential for further optimization of connection pooling
• Additional monitoring metrics
• Enhanced error reporting
• Extended retention policy configuration
