- 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
- 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
