Adds comprehensive BDD test scenarios for configuration hot reloading functionality:
- 10 scenarios covering hot reloading of logging level, feature flags, telemetry settings, JWT TTL
- Scenarios for handling invalid configurations, file deletion/recreation, rapid changes
- Audit logging scenarios for configuration changes
- All scenarios follow black box testing principles using actual HTTP endpoints
The scenarios are marked as pending since the hot reloading feature is not yet implemented.
They will serve as executable specifications for the future implementation.

- 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
Finalize BDD testing framework with:
- Unified step definitions using StepContext struct
- Proper server verification in theServerIsRunning step
- Robust JSON response handling with escaping and newline trimming
- Updated documentation reflecting current implementation
- Test validation script to ensure test quality
- All tests passing with proper black box testing
Key files updated:
- pkg/bdd/steps/steps.go: Unified step definitions
- pkg/bdd/testserver/client.go: Robust response validation
- pkg/bdd/README.md: Godog pattern guide
- doc/BDD_GUIDE.md: Updated usage guide
- adr/0008-bdd-testing.md: Updated ADR with current approach
- scripts/run-bdd-tests.sh: Test validation script
The BDD framework is now production-ready with comprehensive
documentation and proper testing practices.
Implement comprehensive BDD testing framework using Godog:
- Added feature files for greet and health endpoints
- Created test server that runs on port 9191
- Implemented step definitions using Godog's exact patterns
- Fixed undefined step warnings by following Godog conventions
- All tests passing with proper response validation
- Maintained black box testing principles
Key files:
- pkg/bdd/steps/steps.go - Step definitions using StepContext struct
- pkg/bdd/testserver/ - Test server implementation
- features/*.feature - BDD feature files
- pkg/bdd/README.md - Documentation for proper step patterns
The implementation follows Godog's exact pattern suggestions to avoid
undefined step warnings and provides comprehensive API testing.
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.
- Add scripts/build.sh to compile binaries into bin/ directory
- Move all zerolog setup logic from cmd/server/main.go to pkg/config
- Add log level configuration support (trace, debug, info, warn, error, fatal, panic)
- Simplify cmd/server/main.go from 57 to 27 lines (53% reduction)
- Update .gitignore to use bin/ directory instead of individual files
- Document build process and bin directory in AGENTS.md
- Maintain backward compatibility with all existing functionality
- 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
