Native About dialog family

Baseline: 7338078f8ddd924b8cddee35f512f2286072136d. Reviewed TortoiseProc's AboutDlg, TortoiseGitMerge's AboutDlg, Blame's About procedure, IDiff's About resource and their version/credit controls.

The application About entry and Finder About command now open a native TurtleGit window instead of the macOS standard About panel. App menu → About Tools opens separate Merge, Blame, Image Diff and Unified Diff windows. Each uses the renamed tool title, shared TurtleGit artwork, purpose and upstream attribution. The application identity records the custom source and derivatives; earlier screenshots retain their capture-date artwork. Tool variants share the native layout and show the fork's packaged version information; they are not separate standalone executable distributions.

The layout retains a prominent icon/title or animated banner, contributor text, website/source links, selectable Version Information and default OK. The main application also offers Check For Updates. Copy Version Information copies the same diagnostic report displayed in the window, including the host macOS version, architecture and captured selected Git engine. License and Notices open the app's bundled LICENSE/NOTICE. Missing files disable their buttons. Return activates OK; Escape and the standard close control close the owned window. Reopening a tool's About entry reuses its existing window; closing releases its service registration.

Version reports label Bundled components and read bounded manifest files from the application bundle: Git, LFS, SVN/Perl, OpenSSH/OpenSSL and EditorConfig. SVN/Perl versions use the compact installed-component summary in the Git manifest, not its much larger file-hash inventory. They retain the pinned TortoiseGit resource commit when available. These bundled metadata rows never report a custom engine as bundled. A separate Selected Git row now runs --version using the executable/environment captured from General preferences when About opens. It does not inspect the current repository, read credentials or start network work. Unknown, malformed or over-limit metadata is explicitly reported as unknown. The update button uses the existing macOS release/App Store adapter when clicked.

Upstream contributor names are labeled as original TortoiseGit/TortoiseSVN credits, not as authors of this macOS fork. Complete attributions and bundled component licenses remain available through NOTICE and the packaged source kits. The source donation/support workflow is adapted to the upstream contributors link; no donation transaction is performed.

Evidence and remaining work

Two focused Core tests passed with zero failures, checking captured manifest versions, source pins, license/notices availability and malformed/oversize fallback. The unsigned Debug build passed with existing diagnostic noise. See the batch record.

Initial native checks passed all five window constructions and their injected routes. Offscreen full-content captures omitted some standard button labels; they were rejected and are not published. Reviewing their version text found that the bounded reader skipped the large SVN inventory. The report now reads its compact installed-version summary and explicitly checks real SVN/Perl versions.

The repaired native receiver passed all five actual windows, including real bundled Git/SVN/Perl versions, selectable report/private-pasteboard copy, injected license/notices/update targets, default OK and close callbacks. All owned windows closed; no installed application, external URL or update request was launched. The final app build passed. Screenshot acceptance remains open.

Remaining: physical menu/button/keyboard tracking, complete light/dark/resize and VoiceOver acceptance, singleton multi-window and busy/quit interaction, signed bundle/source links and complete upstream animated-banner/credits layout. This is a partial native adaptation, not full application or App Store acceptance.

Source banners, tool layouts and owned reports — October 17, 2026

The main app and Merge About windows now use the source WaterEffect banner. The renamed title and original tool/turtle artwork are rendered natively, with the source eight-neighbor height fields, damping, refraction, color clamp, alternating pages and pointer/drop disturbances. Native bitmap alpha is retained; Windows RGB discarded it. Even raster widths and bounded dimensions/input avoid source out-of-bounds shapes. Native animation follows the source 40 ms cadence and roughly 1.5 second automatic-drop cadence. Reduce Motion restores the static artwork and removes the timer. Occluded/minimized/hidden windows pause it; closing retires timers, observers and tracking areas. Blame/Image/Unified use their own source-style icon/title/version headers and smaller native layouts.

Original contribution text, version group/scroll view, website, upstream support, TortoiseSVN attribution and OK retain their source grouping. Copy/license/notices occupy a separate row so they cannot crowd the source update/OK footer. Effective native minimum constraints replace the old ineffective contentMinSize setting. All five windows still report the shared captured app bundle and remain parts of one native app. The source main About's donation and Merge's contribution links open those upstream pages only when clicked.

Selected Git checks are asynchronous and cancellation-aware, retain the exact executable/environment and reject late publication after closure. Repeated reads while busy are ignored. Quit accounting remains held until the backend actually settles even if the window has closed. Link controls retain their registered URL; mutating a button identifier or retaining a foreign/closed control cannot redirect it. Copy, update and close actions retire once. Tool singleton reuse checks the exact closing controller, so an old close callback cannot remove a replacement. Command-C copies the report when there is no selected native text; ordinary text selection keeps its normal copy behavior.

All 27 source controls across TortoiseProc, Merge, Blame and Image About resources receive partial mappings. The Unified Diff variant remains a native adaptation of its source About command rather than a resource dialog. Banner title text is rendered natively as TurtleGit alongside the original artwork. Pixel/font/retina and all physical pointer/keyboard/VoiceOver/signed bundle acceptance remain open. The complete crash-reporting subsystem is a separate unported family; these version reports do not upload anything.

The grouped checkpoint passed cumulatively: five distinct Core cases, 96 frames against the pinned original C++ implementation, a current Debug app build and the complete five-window native family with system and bundled Git. The source oracle initially used an incorrect unsigned Windows color-getter shim; correcting it to BYTE semantics fixed the oracle without changing the Swift effect. Native repairs covered the default-button assertion, effective full-width layout/footer, an injected visibility signal for prohibited test receivers, and original tool icons. All ten final raw light/dark captures were reviewed; all nine receivers and their private helper paths were independently absent. Detailed attempts and limitations are recorded in the checkpoint.

Actual native timers are exercised, but OS occlusion in an active user session is not proven by these nonactivating receivers. Captures use Reduce Motion and are static, not evidence of animated presentation. Retina banner text sharpness, physical interaction and component-specific APR/APR-util version details remain open alongside the broader acceptance above. Earlier records cover the static implementation.
