release_2.4.1

Bug Fixes

• Fixed crash when DolphinTool executable is missing or inaccessible:
  When DolphinTool.exe could not be found or launched, the error handling code itself would crash with InvalidOperationException: No process is associated with this object. instead of reporting the real problem (e.g. "file not found"). The cleanup logic now safely handles cases where the external process was never started. (292 reports)

• Fixed crash on Windows editions where SetProcessErrorMode is unavailable:
  The error dialog suppression feature (which prevents DolphinTool from showing blocking message boxes) now fails silently on systems that lack this kernel32.dll entry point, instead of crashing the application. (1 report)

Upgraded Dependencies

• SharpCompress 0.49.1 → 0.50.0

What's New

Screenshot Capture (F8)

Press F8 to capture a screenshot of the application window. Screenshots are saved as PNG files in the Screenshot folder inside the application directory. This is handy for sharing your setup, reporting UI issues, or documenting settings.

Serilog Logging Infrastructure

The entire logging system has been migrated to Serilog with structured logging:

• On-screen log viewer — Messages still appear in real time via a custom UiLogSink.
• Rolling daily log files — All messages are written to %LocalAppData%\BatchConvertToRVZ\logs\ with 14-day retention and 10 MB size limits.
• Automatic bug reporting — Warning and Error level events are automatically forwarded to the bug report API through a dedicated BugReportSink. No more manual ReportBugAsync calls scattered across services.

Redesigned Settings Panels

GroupBox controls have been replaced with collapsible Expander panels that are collapsed by default. This reduces visual clutter in the Convert, Verify, and Extract tabs, showing only the settings you need when you need them.

Updated Color Scheme

• Terminal output is now white (#ffffff) instead of green — cleaner and more readable.
• All action buttons (Start, Cancel, About, Exit) now share a unified cyan/sky-blue color palette (#00bcd4), replacing the previous multi-color scheme.

Process Error Dialog Suppression

A new ProcessHelper.SuppressErrorDialogs() method prevents Windows error dialogs (like "Ignore and continue?") from blocking batch operations when DolphinTool encounters issues. The error mode is set before spawning DolphinTool processes.

Improved Error Dialog Safety

The blocking .GetAwaiter().GetResult() call for showing MessageBox from non-UI threads has been replaced with a safer Application.Current.Dispatcher.Invoke() pattern, eliminating potential deadlocks.

Code Cleanup

• Removed XML documentation comments from service classes.
• Service constructors now accept ILogger directly instead of Action<string> and Func<string, Exception?, Task> delegates.
• ConversionService, ExtractionService, and VerificationService log through Serilog with source context via .ForContext<T>().
• Global exception handlers in App.xaml.cs log through Serilog and use a dedicated TryReportFatal method for direct bug reporting on fatal crashes.

---

Full Changelog: release_2.3.1...release_2.4.0

release_2.3.1

Bug Fixes

• Fixed false bug reports for missing DolphinTool.exe - The application no longer reports missing DolphinTool.exe as a bug. It now only displays a local error message, since this is a deployment issue (the file was not included with the application) rather than an application bug.

• Fixed crash when browsing a non-existent extraction folder - Added a directory existence check before attempting to list files. Previously, selecting or entering a folder path that doesn't exist would cause an unhandled DirectoryNotFoundException. The application now gracefully handles this case and displays an appropriate message.

release_2.3.0

Improved 7z Archive Extraction Reliability

Some 7z archives (particularly large or heavily compressed files) would fail to extract due to a limitation in SharpCompress's LZMA decoder, causing the application to crash with an OperationCanceledException.

This version adds a fallback mechanism:

• If SharpCompress fails to extract a 7z archive, the application automatically retries using 7za.exe (7-Zip standalone)
• If both extractors fail, the file is marked as corrupt instead of crashing
• Native ARM64 support via 7za_arm64.exe for Windows on ARM devices

Other Changes

• Updated SharpCompress from 0.48.1 to 0.49.1
• Updated Microsoft.NET.Test.Sdk to 18.6.0
• Added standalone 7za.exe and 7za_arm64.exe executables for ARM64 builds
• Removed unused References folder

Full Changelog: release_2.2.0...release_2.3.0

release_2.2.0

Testing

• New unit test project (BatchConvertToRVZ.Tests) with xUnit and Coverlet coverage
• Tests covering models (FileItem, GitHubRelease) and services (FileService, BugReportService, UpdateService, SharedHttpHandler)

Bug Report Improvements

• Refactored bug report payload to match the API schema (proper message, applicationName, version, environment, stackTrace fields)
• Added structured sections in bug report messages (Environment Details, Error Details, Exception Details)
• Added truncation of message (4000 chars) and stack trace (8000 chars) fields to prevent oversized requests
• Removed unused fields from SystemInfo model (BaseDirectory, TempPath, ExceptionType, ExceptionMessage, etc.)

Error Reporting

• Added automatic bug report calls across ConversionService, ExtractionService, and VerificationService when processing fails
• Added bug report calls in MainWindow for drag-and-drop errors, file add failures, and URL open errors

FileService Cleanup

• Streamlined FileService to a pure utility with no dependencies — removed Action<string> logger parameter and all wrapper methods (file operations now use System.IO directly at call sites)

Enhanced Shutdown Reliability

• Window closing logic no longer blocks when the app is already shutting down via Application.Current.Shutdown()
• Added fallback to Environment.Exit(0) if graceful shutdown fails, with a 3-second force-exit timeout

Folder Path Validation

• Input folder and verification folder validation now checks for null/empty paths and folder existence before file enumeration
• Clear error messages logged when folder paths are invalid

Verification: Include Subfolders

• New "Include subfolders" checkbox on the Verification tab — allows recursive scanning for RVZ files
• Verification file count message now indicates whether subfolders were included

UI Polish

• Added tooltips across the UI: file list labels, Select/Deselect buttons, statistic cards, extraction overlay, and output format selector
• Improved drag-and-drop tooltip hints on DataGrids

Dependencies

• SharpCompress updated from 0.47.4 to 0.48.1

Internals & Maintainability

• AssemblyInfo.cs now exposes internals to the test project (InternalsVisibleTo)
• Async naming convention: TryDeleteFile → TryDeleteFileAsync, TryDeleteDirectory → TryDeleteDirectoryAsync
• UpdateService and BugReportService methods made internal for testability
• Removed .DotSettings.user files from tracking; added to .gitignore

Full Changelog: release_2.1.0...release_2.2.0
