Pull request overview
This PR refactors the DConfig C++ wrapper class generation tool (dconfig2cpp) to improve thread safety and lifecycle management. The refactor introduces a data layer separation pattern, enhances the state machine from 3 states to 5 states, and implements atomic operations for thread-safe state transitions.
Key changes:
- Introduces a Data class (TreelandUserConfigData) to separate internal data management from the public API (TreelandUserConfig)
- Expands state machine from Invalid/Succeed/Failed to Invalid/Initializing/Succeed/Failed/Destroyed with atomic CAS operations
- Separates thread responsibilities: updateValue() in worker thread, updateProperty() in main thread with QMetaObject::invokeMethod for proper thread context

…lifecycle management Problem: - Single-threaded design with weak state machine (Invalid -> Succeed/Failed) - No proper handling of object destruction during initialization - Signal emissions in worker thread context (incorrect thread context) - Fragile destructor unable to handle all cleanup scenarios Solution: 1. Introduce Data layer separation (TreelandUserConfigData + TreelandUserConfig) - Clear separation between internal data management and public API - Enables safer object lifecycle management 2. Enhance state machine (3-state -> 5-state model) - Add Initializing and Destroyed states - Use atomic CAS operations for thread-safe state transitions - States: Invalid -> Initializing -> (Succeed | Failed | Destroyed) 3. Improve async initialization and cleanup - Use QPointer for safe backref checks (prevent use-after-free) - Support 4 destruction paths: normal/failed/quick/mid-initialization - Atomic state transitions with proper signal emission guards 4. Separate thread responsibilities - updateValue(): Worker thread reads config values - updateProperty(): Main thread updates properties and emits signals - Use QMetaObject::invokeMethod for correct thread context Improvements: - Thread safety: Complete atomic operations coverage - Memory safety: QPointer guards prevent dangling pointers - Code clarity: Layered architecture with clear responsibilities - Backward compatibility: API unchanged
dconfig has deprecated the isInitializeSucceed interface.
