- ✅ **apt-layer.sh Integration**: Updated apt-layer.sh and related scriptlets to use the correct service name and ensure proper daemon status detection and management
|
||||
- ✅ **End-to-End D-Bus Testing**: Successfully tested D-Bus method/property calls and signal emission via busctl and apt-layer.sh, confirming full integration and correct daemon operation after VM reboot and service migration
|
||||
- ✅ **Phase 1: Foundation & Core Decoupling**: Core daemon logic is now fully decoupled from D-Bus. The core daemon is pure Python with no D-Bus dependencies, D-Bus setup is consolidated in the main entry point, D-Bus interfaces are thin wrappers with no business logic, and all circular imports are eliminated. Also fixed a syntax error in interface_simple.py.
|
||||
- ✅ **Phase 2: dbus-next Property/Signal Refactor**: All D-Bus properties now use @dbus_property with correct access, all D-Bus signals use .emit(), the legacy main function is removed, and the daemon is tested and running cleanly after the refactor.
|
||||
|
||||
### Daemon Integration (COMPLETED)
|
||||
- ✅ **D-Bus Interface**: Complete D-Bus interface implementation with sysroot and transaction interfaces

- D-Bus interfaces are thin wrappers, no business logic

- Syntax error in interface_simple.py fixed
|
||||
- 🎯 **Phase 2: Implementing dbus-next Correctly & Decoupling Logic**
|
||||
- Implement all D-Bus properties using `@dbus_property` decorators
|
||||
- Correctly define and emit D-Bus signals using `@signal()` and `.emit()`
|
||||
- Integrate progress callbacks into `ShellIntegration` for real-time updates
|
||||
- Refactor methods for proper asynchronous operations with `asyncio`
|
||||
- Remove all legacy `dbus-python` code and hybrid patterns

- ✅ **Phase 2: dbus-next Property/Signal Refactor**
|

- All D-Bus properties use @dbus_property with correct access
|

- All D-Bus signals use .emit()

- Legacy main function removed
|

- Daemon tested and running cleanly after refactor
|
||||
- 🎯 **Phase 3: Testing & Cleanup**
|
||||
- Implement comprehensive integration tests using `dbus-next` as client
|
||||
- Service activation, introspection, method call, and signal monitoring tests

### Added
|

- **Phase 1: Foundation & Core Decoupling**: Major architectural refactor.
|
||||
- Core daemon logic is now pure Python with no D-Bus dependencies.
|
||||
- D-Bus setup is consolidated in the main entry point (`apt_ostree_new.py`).
