hellobertrand/zxc v0.3.3 on GitHub

This release focuses on CLI stability and I/O performance optimizations, resolving issues with archive consistency across different output targets.

Changes

Fixed stdout consistency: Resolved a memory management issue in the CLI where custom buffers were freed before stream closure, causing size discrepancies when redirecting output to stdout (Issue #36).
Buffer management: Improved setvbuf handling to ensure safe teardown and flushing of I/O streams across all platforms (Linux, Windows, macOS).
Increments patch version to 0.3.3 by @tansy
Fixes buffering issues with stdin and stdout by @tansy & @hellobertrand in #37

Acknowledgments

A special thank you to @tansy for identifying the archive size discrepancy and providing the comprehensive test case required for reproduction and verification.

Unsure? Use the generic x86-64 build for universal compatibility.

CPU Feature Detection (x86)

# Linux
grep -E 'avx512|avx2' /proc/cpuinfo | head -1

# Windows (PowerShell)
Get-WmiObject Win32_Processor | Select-Object Name

Performance

x86-64: Baseline (SSE2)
AVX2: ~20-30% faster than baseline
AVX512: ~40-60% faster than baseline (tested with Intel SDE)

Build from Source

For optimal CPU-specific performance:

git clone https://github.com/hellobertrand/zxc.git
cd zxc && mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DZXC_NATIVE_ARCH=ON ..
cmake --build . --parallel

Enables -march=native for maximum SIMD utilization.
