[1.0.3] - 2026-02-28
Changed
- Breaking: Flattened JSON output structure - removed
apacheandnetworksubdivisions - All log fields are now merged into a single-level JSON structure for easier parsing
- ClickHouse schema updated: replaced
apache JSONandnetwork JSONcolumns with singlefields JSONcolumn
Technical Details
- Custom
MarshalJSON()implementation flattens all fields at the root level - Backward compatibility: existing ClickHouse tables need schema migration to use
fields JSONcolumn
[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_typeconfiguration for Unix socket sources to prevent source detection spoofing
Changed
- Unix socket sources now support explicit
source_typefield 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) withsource_typedocumentation
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

- 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)

- 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
[1.0.0] - 2026-02-27
Added
