# Changelog

This file tracks changes made during development sessions. After each git commit, this file is cleared to start fresh.

## Commands Enhanced
- `shlib-backend` - Added real logic for shared library backend operations
- `internals` - Enhanced with comprehensive system diagnostics and health checks
- `apply-live` - Completed implementation for live system updates
- `testutils` - Completed synthetic data generation and testing utilities

## Features Added
- Daemon functionality completed (DBus interface, transaction management, APT operations)
- APT integration analysis completed (hardiness check)
- APT tool blocking implementation guide created for debian-atomic project

## Technical Improvements
- Removed unused `apt-pkg-native` dependency from Cargo.toml
- Verified all APT operations use command-line tools for reliability
- Created comprehensive APT blocking implementation documentation
- **Comprehensive .gitignore cleanup** - Added patterns for all build artifacts and test files
- **Removed tracked build artifacts** - Cleaned up debian/cargo/, debian/.debhelper/, and package files

## Files Modified
- `src/daemon/dbus_new.rs` - Completed all DBus interface methods
- `src/commands/shlib_backend.rs` - Added real implementation
- `src/commands/internals.rs` - Enhanced with real system diagnostics
- `src/commands/apply_live.rs` - Completed implementation
- `src/commands/testutils.rs` - Completed implementation
- `Cargo.toml` - Cleaned up unused dependencies
- `apt-hardiness-report.md` - Created comprehensive APT integration report
- `apt-tool-blocking-implementation.md` - Created implementation guide for debian-atomic
- `.gitignore` - **COMPLETELY OVERHAULED** - Added comprehensive patterns for all build artifacts

## Major Milestone Achieved
- **Daemon Implementation Completed** ✅
  - All DBus interface methods implemented
  - Real transaction management working
  - Real APT operations functional
  - Client management system operational
  - Update detection and configuration reload working

## APT Integration Analysis Completed
- **APT Hardiness Check** ✅
  - Analyzed all APT-related commands and functionality
  - Verified command-line approach is superior to library bindings
  - Discovered `apt-pkg-native` was never actually used
  - Confirmed hybrid command-line approach is optimal
  - Created comprehensive report documenting findings

## APT Tool Blocking Implementation Guide
- **Created comprehensive guide** for debian-atomic project
  - Explains how to block traditional APT tools on atomic systems
  - Provides wrapper script implementations
  - Details integration with deb-bootc-compose
  - Includes testing and troubleshooting procedures
  - Based on ublue-os DNF/YUM blocking approach

## Unused Dependency Cleanup
- **Removed `apt-pkg-native` dependency** from Cargo.toml
- **Verified build still works** without the dependency
- **Updated documentation** to reflect command-line APT integration approach
- **Removed 6 additional unused dependencies**:
  - `pkg-config` (both dependencies and build-dependencies)
  - `walkdir` (file system operations)
  - `lazy_static` (lazy initialization)
  - `futures` (async utilities)
  - `async-trait` (async trait support)
  - `cap-std` and `cap-std-ext` (capability-based operations)
- **Removed dead code** - deleted unused `parallel.rs` module
- **Build verified working** after cleanup

## Git Repository Cleanup
- **Comprehensive .gitignore overhaul** ✅
  - Added patterns for all Debian build artifacts (*.deb, debian/.debhelper/, debian/cargo/)
  - Added patterns for package archives (*.tar, *.tar.gz, *.zip)
  - Added patterns for test artifacts and build stamps
  - Added patterns for environment and local configuration files
- **Removed tracked build artifacts** ✅
  - Cleaned up `debian/cargo/` (hundreds of build files)
  - Cleaned up `debian/.debhelper/` (build helper files)
  - Removed `quay.io_example_debian_latest.tar` (unclear purpose)
  - Repository now properly ignores all build artifacts

## Usage Instructions
1. **Track changes** during development sessions
2. **Copy relevant sections** to git commit messages
3. **Run `./clear-changelog.sh`** after committing to reset for next session
