## Post-Refactor Bug Fix
|
||||
|
||||
### Critical Crash: Nullptr Dereference (Commit 0fe2efc)
|
||||
|
||||
**Problem Discovered:**
|
||||
- Refactor compiled successfully but crashed immediately at runtime
|
||||
- Stack trace: `UIManager::updatePhysicalWindowSize()` → `Engine::updatePhysicalWindowSize()` → `Engine::initialize()`
|
||||
- Root cause: `Engine::initialize()` line 228 called `updatePhysicalWindowSize()` BEFORE creating `ui_manager_` at line 232
|
||||
|
||||
**Solution Implemented:**
|
||||
```cpp
|
||||
// BEFORE (crashed):
|
||||
updatePhysicalWindowSize(); // Calls ui_manager_->updatePhysicalWindowSize() → nullptr dereference
|
||||
ui_manager_ = std::make_unique<UIManager>();
|
||||
|
||||
// AFTER (fixed):
|
||||
int window_w = 0, window_h = 0;
|
||||
SDL_GetWindowSizeInPixels(window_, &window_w, &window_h);
|
||||
physical_window_width_ = window_w;
|
||||
physical_window_height_ = window_h;
|
||||
ui_manager_ = std::make_unique<UIManager>();
|
||||
ui_manager_->initialize(renderer_, theme_manager_.get(), physical_window_width_, physical_window_height_);
|
||||
```
|
||||
|
||||
**Additional Documentation:**
|
||||
- Added comments to `engine.h` explaining pragmatic state duplication (Engine ↔ StateManager)
|
||||
- Documented facade pattern stubs in `shape_manager.cpp` with rationale for each method
|
||||
- Clarified future migration paths
|
||||
|
||||
**Verification:**
|
||||
- ✅ Compilation successful
|
||||
- ✅ Application runs without crashes
|
||||
- ✅ All resources load correctly
|
||||
- ✅ Initialization order corrected
