GitHub Workflows for hfsutils

This directory contains GitHub Actions workflows for continuous integration and testing.

Workflows

CI Workflow (.github/workflows/ci.yml)

Comprehensive continuous integration workflow that builds and tests hfsutils on multiple platforms.

Jobs

1. build-and-test-ubuntu

   • Platform: Ubuntu Latest
   • Builds complete project using build.sh
   • Creates symlinks for filesystem utilities
   • Runs comprehensive test suite:
     • Basic functionality tests
     • Integration workflow tests
     • HFS+ specific tests
     • Error handling tests
     • Specification conformance tests
   • Tests installation to verify package structure
   • Uploads artifacts on failure for debugging

2. build-and-test-archlinux

   • Platform: Arch Linux (container)
   • Same test suite as Ubuntu
   • Validates compatibility with rolling-release distribution
   • Uses latest Arch Linux packages
   • Independent artifact upload for debugging

3. test-specification-conformance

   • Platform: Ubuntu Latest
   • Runs after successful Ubuntu build
   • Validates HFS/HFS+ specification compliance:
     • HFS Alternate MDB Location: Verifies signature 0x4244 at device_size - 1024
     • HFS+ Alternate Volume Header: Verifies signature 0x482B or 0x4244 at device_size - 1024
     • HFS+ attributes Field: Validates kHFSVolumeUnmountedBit (0x0100) is set
   • Uses hexdump to inspect binary structures
   • Ensures conformance to Apple TN1150 specification

4. cross-platform-compatibility

   • Platform: Ubuntu Latest
   • Runs after all builds complete
   • Summary job to verify all platforms passed
   • Provides single checkpoint for PR approval

Test Categories

The test suite (test/run_tests.sh) includes:

• basic: Core functionality (mount, ls, copy, etc.)
• integration: Real-world workflows (backup, migration, archive)
• hfsplus: HFS+ specific features (formatting, detection, journaling)
• errors: Error handling and edge cases
• all: Complete test suite

Triggers

• Push: Any push to master branch
• Pull Request: Any PR targeting master branch

Dependencies

Ubuntu:

• build-essential
• gcc
• make
• perl
• hexdump
• util-linux

Arch Linux:

• base-devel
• gcc
• make
• perl
• git
• util-linux

Running Tests Locally

Ubuntu/Debian

sudo apt-get install build-essential gcc make perl hexdump
./build.sh
cd test
./run_tests.sh all

Arch Linux

sudo pacman -S base-devel gcc make perl util-linux
./build.sh
cd test
./run_tests.sh all

Quick Tests

cd test
./run_tests.sh basic  # Basic functionality only

Specification Tests

cd test
./test_hfs_spec_validation.sh
./test_hfsplus_complete.sh

Artifacts

On test failure, the following artifacts are uploaded:

• test/temp/ - Temporary test files and images
• test/*.log - Test execution logs
• *.img - HFS/HFS+ disk images created during tests

Artifacts are kept for 90 days and can be downloaded from the Actions tab.

Status Badges

Add to README.md:

Maintenance

Adding New Tests

1. Add test function to test/run_tests.sh
2. Update workflow to include new test category if needed
3. Test locally before pushing

Updating Dependencies

1. Update package lists in workflow file
2. Test in container locally:

   docker run -it --rm -v $(pwd):/workspace -w /workspace ubuntu:latest bash
   # or
   docker run -it --rm -v $(pwd):/workspace -w /workspace archlinux:latest bash
   

Debugging Failures

1. Check Actions tab for logs
2. Download artifacts if available
3. Reproduce locally using same commands
4. Check specification conformance with hexdump
