- Fixed kafka-go writer metadata loop by addressing protocol mismatches:
* ApiVersions v0: Removed throttle_time field that kafka-go doesn't expect
* Metadata v1: Removed correlation ID from response body (transport handles it)
* Metadata v0: Fixed broker ID consistency (node_id=1 matches leader_id=1)
* Metadata v4+: Implemented AllowAutoTopicCreation flag parsing and auto-creation
* Produce acks=0: Added minimal success response for kafka-go internal state updates
- Cleaned up debug messages while preserving core functionality
- Verified kafka-go writer works correctly with WriteMessages completing in ~0.15s
- Added comprehensive test coverage for kafka-go client compatibility
The kafka-go writer now works seamlessly with SeaweedFS Kafka Gateway.
VALIDATION LAYER: Comprehensive Docker setup verification
## Docker Setup Validation Tests:
- docker_setup_test.go: Validates all Docker Compose infrastructure
- File existence verification (docker-compose.yml, Dockerfiles, scripts)
- Configuration validation (ports, health checks, networks)
- Integration test structure verification
- Makefile target validation
- Documentation completeness checks
## Test Coverage:
✅ Docker Compose file structure and service definitions
✅ Dockerfile existence and basic validation
✅ Shell script existence and executable permissions
✅ Makefile target completeness (30+ targets)
✅ README documentation structure
✅ Test setup utility validation
✅ Port configuration and network setup
✅ Health check configuration
✅ Environment variable handling
## Bug Fixes:
- Fixed function name conflict between testSchemaEvolution functions
- Resolved compilation errors in schema integration tests
- Ensured proper function parameter matching
## Validation Results:
All Docker setup validation tests pass:
- TestDockerSetup_Files: ✅ All required files exist and are valid
- TestDockerSetup_Configuration: ✅ Docker configuration is correct
- TestDockerSetup_Integration: ✅ Integration test structure is proper
- TestDockerSetup_Makefile: ✅ All essential targets are available
This validation layer ensures the Docker Compose setup is complete
and ready for production use, with comprehensive checks for all
infrastructure components and configuration correctness.
