- Added CheckDatabaseHealth() method to UserRepository interface
- Implemented database connectivity check in SQLite repository
- Enhanced /ready endpoint to verify database health before reporting ready
- Improved readiness logic: checks both server shutdown status and database connectivity
- Better observability: Logs database health check failures with warnings
Benefits:
- More accurate readiness reporting for Kubernetes/container environments
- Detects database connectivity issues before accepting traffic
- Prevents application from accepting requests when database is unavailable
- Maintains backward compatibility with existing readiness checks
Implementation:
- Simple COUNT query to test database responsiveness
- Graceful handling of database unavailability
- Proper HTTP 503 status when not ready
- Comprehensive logging for troubleshooting
Testing:
- ✅ Readiness endpoint returns true when database is healthy
- ✅ Readiness endpoint returns false when database is unhealthy
- ✅ All existing functionality preserved
- ✅ All 25 BDD scenarios passing
- ✅ All unit tests passing

- Added persistence telemetry configuration option (telemetry.persistence.enabled)
- Created PersistenceTelemetryConfig struct for fine-grained control
- Added GetPersistenceTelemetryEnabled() helper method
- Implemented telemetry span creation in SQLite repository
- Added OpenTelemetry instrumentation to key repository methods:
- CreateUser: Tracks user creation with error recording
- GetUserByUsername: Tracks queries with username attribute
- Maintained backward compatibility - telemetry is optional and disabled by default
- Updated all tests to pass config parameter to repository constructor
- Added proper error recording and span attributes for observability
Benefits:
- Performance monitoring of database operations
- Flamegraph generation capability for persistence layer
- Distributed tracing across service boundaries
- Configurable instrumentation for production vs development

- Added /api/v2/greet POST endpoint with JSON request/response
- Implemented ServiceV2 with Hello my friend <name>! greeting format
- Added api.v2_enabled feature flag (default: false)
- Extended BDD tests to cover v2 scenarios
- Maintained full backward compatibility with v1 API
- Added DLC_API_V2_ENABLED environment variable support
- Created ADR 0010-api-v2-feature-flag.md
- Updated configuration system to support API versioning
The time.Sleep(100ms) after OpenTelemetry shutdown was removed as it's
not necessary for proper log writing. Zerolog automatically flushes logs
on program exit, and the remaining 1-second sleep for readiness
propagation is sufficient.
Tested that all shutdown logs are properly written without the sleep.
- Simplify cmd/server/main.go from 158 to 57 lines (64% reduction)
- Move HTTP server creation, graceful shutdown, and context management to pkg/server
- Add Run() method to encapsulate server lifecycle management
- Maintain all existing functionality and OpenTelemetry integration
- Improve separation of concerns and code organization
This refactoring makes cmd/server/main.go a thin entrypoint while moving all server implementation details to the pkg/server package, following Go best practices for package organization.
Add server and greet binaries to .gitignore
Implement readiness endpoint (/api/ready) that returns:
- {"ready":true} (HTTP 200) during normal operation
- {"ready":false} (HTTP 503) during graceful shutdown
Key changes:
- Added readiness context to control readiness state
- Modified server.NewServer() to accept readiness context
- Implemented handleReadiness() with context-aware logic
- Updated cmd/server/main.go to manage readiness state
- Readiness set to false when shutdown signal received
- Updated test script to validate readiness behavior
- Added comprehensive documentation for readiness endpoint
This allows Kubernetes/service meshes to stop routing traffic
to the pod during graceful shutdown while allowing existing
requests to complete. Health endpoint continues to return
happy status during shutdown for proper orchestration.
- Added signal.NotifyContext for modern signal handling in cmd/server/main.go
- Implemented BaseContext for proper context propagation to HTTP handlers
- Added readiness drain delay before shutdown for graceful degradation
- Fixed PID detection in start-server.sh to target actual server process
- Added Logging.JSON configuration option with DLC_LOGGING_JSON environment variable
- Created comprehensive test script that validates entire server lifecycle
- Updated documentation with JSON logging configuration examples
- All shutdown logs now appear correctly in JSON format
- Server terminates gracefully on SIGTERM with proper log flushing
The graceful shutdown implementation follows VictoriaMetrics best practices:
1. Catches termination signals (SIGTERM, SIGINT)
2. Stops accepting new requests but allows ongoing requests to complete
3. Waits for active requests to finish within configured timeout
4. Releases resources and performs cleanup
5. Logs all shutdown steps for observability
Test script validates:
- Server startup and API functionality
- Graceful shutdown sequence
- JSON log format validation
- Complete log sequence verification
- Proper signal handling and context propagation
