ArgsTemplate `{cfg}` placeholder not handled when ConfigFile is empty -**Location**: `HatariLauncher.cs:36` -**Problem**: If `Hatari.ConfigFile` is empty string (allowed per config) but `ArgsTemplate` contains `{cfg}`, the replacement produces `-c "" --disk-a "path"` which Hatari may reject. -**Fix**: Conditionally remove `-c "{cfg}"` when `_cfgPath` is empty, or validate template matches config. - -### 2. `MenuRenderer.RedrawEntry()` potential crash on console resize -**Location**: `MenuRenderer.cs:67-98` -**Problem**: If console resizes smaller since last draw, `row` parameter may exceed new `availableLines`. The `else` branch writes directly via `WriteConsoleLine` without bounds checking against actual console height, risking `ArgumentOutOfRangeException` on `Console.SetCursorPosition`. -**Fix**: Validate `row < Console.WindowHeight` before writing, or clamp to valid range. +_No open critical bugs._ ## Medium Bugs -### 3. `HatariLauncher` constructor doesn't validate `ArgsTemplate` -**Location**: `HatariLauncher.cs:12-24` -**Problem**: Constructor validates `exePath` existence but allows empty/null `argsTemplate`. `Launch()` will fail at runtime with empty string replace. Defense-in-depth validation missing. -**Fix**: Add `if (string.IsNullOrWhiteSpace(argsTemplate) || !argsTemplate.Contains("{zip}")) throw ...;` - -### 4. ZIP launch doesn't validate file exists on disk -**Location**: `InputController.cs:185-196` -**Problem**: `PatchPath` or `RootPath` used directly without checking `File.Exists()`. Overlay logic should prevent this, but no defense-in-depth. -**Fix**: Validate `File.Exists(zipToLaunch)` before calling `_hatariLauncher.Launch()`. +_No open medium bugs._ ## Documentation Inconsistencies -### 5. `Hatari.ConfigFile` required status unclear -**Location**: `README.md:96` vs `LauncherApp.cs:67-68` -**Conflict**: README marks `Hatari.ConfigFile` as required (✅). Code allows empty string and only validates if non-empty. If template uses `{cfg}` but ConfigFile empty → broken args. -**Resolution**: ConfigFile is now optional. When empty, the bundled `MarcerGameDvd-Hatari.cfg` (shipped in the release) is used automatically. README updated to reflect this. ✅ Fixed - -### 6. `RightArrow` key binding missing from AGENTS.md requirements -**Location**: `AGENTS.md:57-58` vs `InputController.cs:172-173` -**Conflict**: AGENTS.md lists only Arrow up/down, Enter, Backspace, ESC, PageUp/Down, `?`. Code also handles `ConsoleKey.RightArrow` as alias for Enter (open folder/launch ZIP). README correctly documents it. -**Resolution**: Update AGENTS.md to include RightArrow. - -### 7. `ShowModalUntilReturnReleased` race condition on resize -**Location**: `ProgramHelpers.cs:62-98` -**Problem**: Captures `lastRow = AvailableLines` at start. If console resizes during the modal wait loop, the clear writes to stale row position. -**Fix**: Re-read `AvailableLines` before clearing, or lock console during modal (not easily possible). +_No open documentation inconsistencies._ ## Code Quality / Minor -### 8. `ProgramHelpers.ShowConsoleMessage` signature could use `params` -**Location**: `ProgramHelpers.cs:110` -**Current**: `public static void ShowConsoleMessage(string[] lines, ...)` -**Called as**: `ShowConsoleMessage([...], ...)` (collection expression) -**Suggestion**: Change to `params string[] lines` for more idiomatic usage. - -### 9. `OverlayDirectoryBrowser` patch path computation order -**Location**: `OverlayDirectoryBrowser.cs:47-50` -**Observation**: Path traversal protection (`IsSubPathOf`) runs after `Path.Combine` but before `Directory.Exists`. Logic appears correct, but worth verifying with `rel` containing `..` when patch layer enabled. +_No open code quality issues._ --- @@ -68,13 +31,16 @@ | `Hatari.ConfigFile` optional with bundled fallback | ✅ Done | Empty ConfigFile falls back to bundled `MarcerGameDvd-Hatari.cfg` | | `FavoritesService.Save()` swallow comment | ✅ Done | Explains intentional behavior | | `UIErrorService` no-rethrow doc | ✅ Done | Explains design decision | +| ArgsTemplate `{cfg}` empty ConfigFile fallback | ✅ Done | `HatariLauncher.Launch()` falls back to bundled config | +| `MenuRenderer.RedrawEntry()` resize bounds check | ✅ Done | Row validated against `availableLines` + `Console.WindowHeight`, catch in `WriteConsoleLine` | +| `HatariLauncher` ArgsTemplate validation | ✅ Done | Constructor validates both `{zip}` and `{cfg}` placeholders | +| ZIP launch file existence check | ✅ Done | `File.Exists` defense-in-depth in `InputController` | +| `RightArrow`/`LeftArrow` in AGENTS.md | ✅ Done | Added to key bindings | +| `OverlayDirectoryBrowser` path traversal | ✅ Non-issue | `..` segments filtered at entry, `IsSubPathOf` as additional safety net | +| `ShowConsoleMessage` params overload | ✅ Done | Added convenience overload with flat argument list | --- ## Priority Recommendation -1. **Fix #1 (ArgsTemplate `{cfg}`)** - ✅ Fixed: empty ConfigFile now falls back to bundled config -2. **Fix #2 (RedrawEntry bounds)** - Potential crash on resize -3. **Fix #3 (HatariLauncher validation)** - ✅ Done (per BUGS.md Fixed table) -4. **Fix #4 (ZIP path validation)** - User-facing robustness -5. **Sync #5 & #6 (docs)** - ✅ Done: ConfigFile documented as optional with fallback \ No newline at end of file +All identified issues have been resolved.
