## [1.0.2] - 2026-02-28
|
|
|
|
### Fixed
|
|
|
|
- **Critical**: Added missing ClickHouse driver dependency (`github.com/ClickHouse/clickhouse-go/v2`)
|
|
- **Critical**: Fixed race condition in orchestrator - reduced from two goroutines to one per source
|
|
- **Security**: Added explicit `source_type` configuration for Unix socket sources to prevent source detection spoofing
|
|
|
|
### Changed
|
|
|
|
- Unix socket sources now support explicit `source_type` field in configuration:
|
|
- `"A"` or `"apache"` or `"http"` for Apache/HTTP logs
|
|
- `"B"` or `"network"` or `"net"` for network logs
|
|
- Empty string `""` for automatic detection (backward compatible)
|
|
- Updated example configuration (`config.example.yml`) with `source_type` documentation
|
|
|
|
### Added
|
|
|
|
- Comprehensive test suite improvements:
|
|
- Added tests for source type detection (explicit + auto-detect fallback)
|
|
- Added tests for config validation (duplicate names/paths, empty fields, ClickHouse settings)
|
|
- Added tests for helper functions (`getString`, `getInt`, `getInt64`)
|
|
- Added tests for port validation in JSON parsing
|
|
- Added tests for MultiSink Flush/Close operations
|
|
- Added tests for FileSink path validation and file operations
|
|
- Added tests for CorrelationService buffer management and flush behavior
|
|
- Test coverage improved from 50.6% to 62.0%
|
|
- All tests now pass with race detector enabled
|
|
|
|
### Technical Debt
|
|
|
|
- Fixed unused variable in `TestCorrelationService_FlushWithEvents`
|
|
- Added proper error handling for buffer overflow scenarios
|
|
- Improved code documentation in configuration examples
|

## [1.0.1] - 2026-02-28
|
|
|
|
### Added
|
|
|
|
- Initial RPM packaging support for Rocky Linux 8/9 and AlmaLinux 10
|
|
- Docker multi-stage build pipeline
|
|
- Hexagonal architecture implementation
|
|
- Unix socket input sources (JSON line protocol)
|
|
- File output sink (JSON lines)
|
|
- ClickHouse output sink with batching and retry logic
|
|
- MultiSink for fan-out to multiple destinations
|
|
- Time-window based correlation on `src_ip + src_port`
|
|
- Graceful shutdown with signal handling (SIGINT, SIGTERM)
|
|
- Configuration validation with sensible defaults
|
|
- Basic observability (structured logging to stderr)
|
|
|
|
### Configuration
|
|
|
|
- YAML-based configuration file
|
|
- Support for multiple Unix socket inputs
|
|
- Configurable time window for correlation
|
|
- Orphan event policy (Apache always emit, Network drop)
|
|
- ClickHouse batch size, flush interval, and buffer configuration
