Matrix Release Build Implementation Summary

Date: 2025-11-11 Status: ✅ COMPLETED Following Patterns: ripgrep and jiff

Overview

Successfully implemented comprehensive matrix release builds that work consistently locally and in CI, following proven patterns from successful Rust projects ripgrep and jiff.

🚀 What Was Implemented

Phase 1: Enhanced Local Development Scripts ✅

1. scripts/test-matrix.sh - Local Matrix Testing

• Purpose: Mirrors CI builds exactly for local development
• Features:
  • Tests multiple targets and feature combinations
  • Supports quick testing modes (--quick)
  • TUI-specific testing (--tui-only)
  • Feature flag combinations
  • Cross-compilation support
  • Comprehensive test reporting

Usage Examples:

./scripts/test-matrix.sh              # Full matrix test
./scripts/test-matrix.sh --quick      # Quick test (primary target only)
./scripts/test-matrix.sh aarch64-unknown-linux-gnu  # Test specific target

Phase 2: Build Configuration Optimization ✅

2. Enhanced Cargo.toml with release-lto Profile

• Added: release-lto profile following ripgrep patterns
• Features:
  • LTO (Link Time Optimization) enabled
  • Code generation units optimized to 1
  • Maximum optimization level (3)
  • Panic mode set to "abort" for better performance

Profile Benefits:

• Smaller binary sizes
• Better runtime performance
• Optimized for production releases

Phase 3: Enhanced CI Check Script ✅

3. Updated scripts/ci-check-rust.sh with Matrix Support

• New Features:
  • Matrix testing mode (--matrix)
  • Feature flag combinations testing
  • Multiple build profiles (release, debug, release-lto)
  • Enhanced error reporting and summaries
  • Fail-fast option
  • Better binary validation

Usage Examples:

./scripts/ci-check-rust.sh --matrix                    # Matrix testing
./scripts/ci-check-rust.sh --profile release-lto     # Optimized builds
./scripts/ci-check-rust.sh --fail-fast               # Stop on first failure

• ARM variants: armv7-unknown-linux-gnueabihf, armv7-unknown-linux-musleabihf

Phase 6: Feature Matrix Testing ✅

6. scripts/feature-matrix.sh - Feature Flag Testing

• Purpose: Comprehensive feature combination testing following jiff patterns
• Features:
  • Tests all feature combinations systematically
  • Package-specific testing (server, TUI, MCP)
  • WASM build testing
  • Minimal feature testing (no defaults)
  • Compatibility validation
  • Detailed reporting and summaries

Feature Categories:

• Core features (default)
• OpenRouter integration
• MCP integration
• Combined features
• TUI-specific features
• WASM features

Phase 7: Cross-Compilation Configuration ✅

7. .cargo/config.toml - Comprehensive Build Configuration

• Purpose: Centralized cross-compilation settings
• Features:
  • Target-specific linker configurations
  • Cross-rs Docker image mappings
  • Environment variable passthrough
  • Optimized compiler flags
  • WASM configuration
  • Registry and network optimizations
  • FFI library paths
