…ng codebase Integrated community contributions: - PR valyala#49: CGO wrapper improvements for 5-7% performance gain on large buffers - Use void* instead of uintptr_t to avoid memory allocations - Direct Go slice usage via reflect.SliceHeader - PR valyala#25: Advanced Compression API with checksum support - Added CCtx type for advanced compression contexts - Added SetParameter/GetParameter methods - Added Reset and Compress2 methods - Full support for all ZSTD compression parameters - PR valyala#63: Exposed CompressDictLevel as public API - Allows fine-grained control over dictionary compression levels - PR valyala#66: RISC-V 64-bit architecture support - Updated Zig builder to 0.13.0 - Added linux_riscv64 target - PR valyala#60: Memory-optimized dictionary functions - Added NewCDictByRef/NewDDictByRef to avoid data copying - Reduces memory usage for large dictionaries Infrastructure improvements: - Created modern Dockerfile with Alpine Linux and latest Zig - Fixed build process issues with clean target - Updated minimum Go version to 1.24 Code organization: - Moved Docker configs to build/docker/ - Moved scripts to scripts/ - Moved upstream zstd to contrib/ - Moved test data to test/ - Created comprehensive examples in examples/ - Kept all Go source files in root for package compatibility Testing enhancements: - Added Silesia Corpus compression tests with speed measurements - Created 33 aggressive fuzz tests targeting known vulnerabilities - Added comprehensive tests for Advanced API - Added benchmarks comparing raw zstd vs wrapper performance The wrapper now shows 6-10% performance improvements for compression while maintaining identical compression ratios.
