Modern WinUI 3 Presentation Layer +- **Fluent Design & Mica Backdrops**: Leverages modern Windows 11 styling including Mica theme materials matching light and dark modes. +- **Improved UI Elements**: + - Host a modern `TreeView` control for sensor visualization. + - Interactive plot views (`PlotView`) containing a configurable floating top-right plot legend overlay. + - Secondary windows including a floating desktop sensor gadget (`SensorGadgetWindow`) and pop-out graphs. +- **High-DPI Support**: Fixes layout issues on high-DPI scaling displays and tray restore behavior. +- **MVVM Pattern**: Designed around cleanly separated ViewModels (`MainWindowViewModel`, `SensorTreeItemViewModel`, etc.) using Dependency Injection. + +### 2. Startup Performance & Progressive Loading +- **Staged & Async Initialization**: Refactored `Computer.Open()` to support staged/progressive loading. Rather than blocking the main thread on slow motherboard LPC/EC/IPMI, memory SPD, or GPU probes, the UI shell loads immediately and populates hardware groups progressively as background discovery tasks complete. +- **Background TSC Estimation**: Moved CPU TSC (Time Stamp Counter) frequency estimation off the startup blocking path in `GenericCpu.cs`. It now runs asynchronously with full cancellation support. +- **Startup Instrumentation**: Introduced tracing and measurement tools under the `IStartupTracer` abstraction (`FileStartupTracer`, `NoOpStartupTracer`) to track execution time per discovery phase and identify bottlenecks. + +### 3. Architecture & Composition Root Modernization +- **Dependency Injection**: Replaced manual instantiation chains with `Microsoft.Extensions.DependencyInjection`. +- **Decoupled Services**: Extracted logic out of monolithic UI containers into clean, testable service abstractions: + - `IHardwareMonitorService` / `HardwareMonitorService` + - `ILogger` / `Logger` + - `IRemoteWebServer` / `RemoteWebServer` + - `SecondaryWindowCoordinator` (for plot/gadget window lifecycles) + - `TrayIconService` (split into interop, renderer, and orchestration layers) + - `TreeRebuildCoalescer` (debounces and coalesces tree rebuild requests to optimize performance) + - `PlotTrackingService`, `SensorSelectionService`, `WindowPlacementService`, `WindowChromeManager`, and `SensorColumnMeasurer`. + +### 4. Thread Safety, Correctness, and Security Hardening +A comprehensive code review identified and fixed several critical concurrency issues: +- **`Computer.Close()` Race Condition Fix**: `CancelDeferredGroupRun()` now fully drains in-flight deferred tasks (`Task.WaitAll` via `WaitForDeferredGroupTasks`) before disposing token sources, stopping background threads from executing native API / OpCode calls during teardown. +- **Atomic State Transitions**: Wrapped `Open`/`OpenAsync`/`Close` in `Computer.cs` with a new `_openLock` to make checking/setting the `_open` state atomic and prevent concurrent initialization leaks. +- **UI Logger Synchronization**: Added a `_sync` lock inside `Logger` to protect concurrent reads/writes on `_sensors` and `_identifiers` arrays. +- **WinForms UI Thread Marshalling**: Legacy UI forms (`MainForm`, `SystemTray`, `SensorGadget`) were updated to marshal background `HardwareAdded`/`HardwareRemoved` events onto the UI `SynchronizationContext` to prevent unmarshaled cross-thread UI mutation. +- **Memory DIMM Discovery Serialization**: Standardized discovery ordering via `IHardwareDiscoveryTask.StartHardwareDiscovery()`, preventing duplicated or lost DIMM `HardwareAdded` announcements. +- **Web Server Optimization & Security**: + - Fixed a vulnerability in `PasswordHasher.VerifyPbkdf2` where empty salt/hash segments could bypass authentication. + - Reused a static `JsonSerializerOptions` in `RemoteWebServer` to restore metadata caching on the high-frequency `data.json` endpoint. + +--- + +## Detailed Audit & Code Review Fixes + +| Finding | Severity | Component | Resolution | +| :--- | :---: | :--- | :--- | +| **F1** | 🔴 Critical | `Computer.cs` | Drains in-flight deferred tasks during `Close()` to prevent races against native teardown. | +| **F2** | 🔴 Critical | `Computer.cs` | Extracted `OpenCore` and synchronized all open/close paths under `_openLock`. | +| **F3** | 🔴 Critical | `Logger.cs` | Added `_sync` mutex to synchronize sensor collections across threads safely without blocking file I/O. | +| **D1** | 🟠 Major | `GenericCpu.cs` | Deferred TSC task now receives a `CancellationToken` and is fully awaited on `Close()`. | +| **D2** | 🟠 Major | WinForms UI | Captures UI `SynchronizationContext` and dispatches deferred events to the UI thread. | +| **D4** | 🟠 Major | `Computer.cs` | Deferred-DIMM discovery is serialized via `StartHardwareDiscovery()` to avoid event duplication. | +| **D5** | 🔴 Critical | `PasswordHasher.cs` | Enforces non-empty salt/hash checks to prevent empty password bypass. | +| **D6** | 🟠 Major | `Computer.cs` | `CompleteDeferredGroupRunWhenRegistered` re-arms to wait for nested deferred tasks registered late. | +| **D9** | 🟡 Minor | `TrayIconService.cs` | Reuses existing GDI tray icons when tooltips/values are unchanged to avoid rendering churn. | +| **D10**| 🟡 Minor | `PlotTrackingService` | Eliminated redundant full-history sorts on every tick. | +| **D11**| 🟡 Minor | `MainWindowViewModel` | Cached sensor counts instead of traversing the entire tree on every update tick. | + +--- + +## Verification & Testing +All tests and builds run successfully on `Release` for `x64` platform target. + +### Automated Tests +Run the test suites with: +```powershell +# Run Library Unit Tests +dotnet test LibreHardwareMonitorLib.Tests/LibreHardwareMonitorLib.Tests.csproj -c Release -p:Platform=x64 + +# Run WinUI UI Tests +dotnet test LibreHardwareMonitor.Windows.WinUI.Tests/LibreHardwareMonitor.Windows.WinUI.Tests.csproj -c Release -p:Platform=x64 +``` + +### Build Check +Ensure WinForms app compiles without errors: +```powershell +dotnet build LibreHardwareMonitor.Windows.Forms/LibreHardwareMonitor.Windows.Forms.csproj -c Release -p:Platform=x64 +```
