fix(ci): resolve Windows Go builds with MSYS2 UCRT64 and Bundler 4.0#210
Conversation
Replace Chocolatey MinGW installation with MSYS2 setup-msys2 action using UCRT64 environment. This resolves gcc compilation failures with zstd-sys and provides better toolchain isolation for CI builds. Changes: - Use msys2/setup-msys2@v2 action for MinGW-w64 installation - Configure UCRT64 environment for modern Windows builds - Enable path-based triggers for ci-go.yaml workflow - Add proper glob patterns for Go, Rust crates, and CI scripts
Uncomment path filters in ci-python, ci-rust, ci-java, ci-csharp, ci-node, and ci-ruby workflows to prevent unnecessary CI runs on unrelated changes.
Add caching across all CI workflows to reduce installation time: TIER 1 - High Impact: - Cache Tesseract language data (macOS, Linux, Windows) - Extend LibreOffice caching to macOS and Linux - Cache Pandoc binaries (macOS, Linux, Windows) - Cache MSYS2 MinGW-w64 toolchain (Windows) TIER 2 - Medium Impact: - Cache NuGet packages for .NET builds - Cache OpenSSL headers and libraries - Cache Task CLI binary Key improvements: - Install commands now check cache hits before running - Environment variables set regardless of cache status - Platform-specific cache paths optimized - Consolidated duplicate cache steps - Fixed cache key versioning and conflicts Estimated savings: 150-200 minutes/week across all workflows.
The ring crate's build script was failing because: - Building for x86_64-pc-windows-gnu target (MinGW) - But CC=gcc/AR=ar env vars confused the build script - It detected MSVC flags but called GNU ar, causing incompatibility Solution: Let Rust toolchain handle compiler selection automatically for the GNU target. MSYS2 MinGW is still in PATH for when needed. Fixes: ar: invalid option -- : error
The tesseract-rs build script was passing MSVC-style compiler flags (/MD, /O2) to CMake even when building with the Windows GNU target (x86_64-pc-windows-gnu). MSYS2's path translation was converting these flags to invalid paths like C:/Program Files/Git/MD, causing linker failures. This fix adds explicit conditional logic to detect the target environment: - For MSVC targets: Use MSVC-style flags (/MD, /O2, /MDd, /Od) - For GNU targets: Use GCC-style flags (-O2, -DNDEBUG, -O0, -g) - Applied to both CMAKE_C_FLAGS and CMAKE_CXX_FLAGS for consistency - Applied to both leptonica and tesseract build configurations This ensures MSYS2's GCC compiler receives only GCC-compatible flags, eliminating path translation errors and allowing Windows GNU builds to succeed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Complete cleanup of Pandoc-related comments, code, and documentation: - Remove PandocExtractionResult struct from types.rs - Clean Pandoc comparison comments from 12 extractor source files - Remove pandoc-fallback feature comments from Cargo.toml - Update docker/README.md to replace Pandoc with native format descriptions - Update scripts documentation to remove Pandoc mentions - Update CHANGELOG.md for rc.5 to document the complete removal This completes the systematic Pandoc removal from v4 codebase. All formats (LaTeX, EPUB, RTF, etc.) are now handled exclusively by native Rust extractors. Benefits: Simpler installation, faster CI builds (~2-5 min), smaller Docker images (~500MB-1GB reduction), pure Rust codebase with no external process dependencies.

- Add 'permissions: contents: read' to 40 jobs across 4 workflows - Implements principle of least privilege for GITHUB_TOKEN - Resolves all CodeQL security alerts for missing workflow permissions Affected workflows: - publish.yaml (19 jobs) - benchmarks.yaml (18 jobs) - ci-rust.yaml (1 job) - ci-docker.yaml (1 job)
This ensures that cargo build scripts are compiled with the GNU toolchain instead of MSVC, which was causing the ring crate to fail with: 'TARGET = Some(x86_64-pc-windows-msvc)' The rustup default command now explicitly sets stable-x86_64-pc-windows-gnu before any Rust compilation happens.
Setting GEM_HOME and BUNDLE_PATH to empty strings at the job level was causing RubyGems to fail on macOS and Linux with 'No such file or directory' errors when trying to install bundler. These environment variables are only needed on Windows for MAX_PATH mitigation, where they are set to proper short paths (C:\g, C:\b) in the Windows-specific configuration step.
Updated actions/upload-artifact from v4 to v5 in build-wheels action.
