# GitHub Actions Workflows
This directory contains CI/CD workflows for the ZXC compression library.
## Workflows
### build.yml - Build & Release
**Triggers:** Push to main, tags, pull requests, manual dispatch
Builds and tests ZXC across multiple platforms (Linux x86_64/ARM64, macOS ARM64, Windows x64). Generates release artifacts and uploads binaries when tags are pushed.
### build_all.yml - Multi-Architecture Build
**Triggers:** Push to main, pull requests, manual dispatch
Comprehensive build matrix testing across multiple architectures including 32-bit and 64-bit variants for Linux (x64, x86, ARM64, ARM) and Windows (x64, x86). Validates compilation compatibility across different platforms.
### benchmark.yml - Performance Benchmark
**Triggers:** Push to main (src changes), pull requests, manual dispatch
Runs performance benchmarks using LZbench on Ubuntu and macOS. Integrates ZXC into the LZbench framework and tests compression/decompression performance against the Silesia corpus.
### coverage.yml - Code Coverage
**Triggers:** Push to main, pull requests, manual dispatch
Builds the project with coverage instrumentation (`-DZXC_ENABLE_COVERAGE=ON`), runs unit and CLI tests, and generates a coverage report using `lcov`. The report is then uploaded to Codecov for analysis.
### fuzzing.yml - Fuzz Testing
**Triggers:** Pull requests, scheduled (every 3 days), manual dispatch
Executes fuzz testing using ClusterFuzzLite with multiple sanitizers (address, undefined) on decompression and roundtrip fuzzers. Helps identify memory safety issues and edge cases.
### quality.yml - Code Quality
**Triggers:** Push to main, pull requests, manual dispatch
Performs static analysis using Cppcheck and Clang Static Analyzer. Runs memory leak detection with Valgrind to ensure code quality and identify potential bugs.
### wrapper-rust-publish.yml - Publish Rust Crates
**Triggers:** Release published, manual dispatch
Tests and publishes Rust crates to crates.io. Verifies the version matches the release tag, runs tests across platforms, and publishes `zxc-compress-sys` (FFI bindings) followed by `zxc-compress` (safe wrapper).
### wrapper-python-publish.yml - Publish Python Package
**Triggers:** Release published, manual dispatch
Builds platform-specific wheels using `cibuildwheel` for Linux (x86_64, ARM64), macOS (ARM64, Intel), and Windows (AMD64, ARM64). Tests wheels against Python 3.12-3.13, then publishes to PyPI via trusted publishing.
### security.yml - Code Security
**Triggers:** Push to main, pull requests
Runs CodeQL security analysis to detect potential security vulnerabilities and coding errors in the C/C++ codebase.
