Rebase row menus

The Rebase and Cherry Pick row menus now reuse native Log commands and original TortoiseGit icons. This remains a partial port of the upstream Log menu.

The source comparison uses RebaseDlg.cpp and GitLogListBase.cpp at upstream commit 7338078f8ddd924b8cddee35f512f2286072136d. Rebase excludes upstream checkout, reset, revert, merge, recursive Rebase/Cherry Pick, combine and rollup commands. Pick/Skip/Edit/Squash remain available only while editing the plan.

Available inspection commands include comparison with the working tree or parent, two-revision comparison, unified diff, Show Log, repository browsing, Branch, Tag, Push, Notes and Format Patch. A clipboard submenu provides details with or without paths, hashes, authors, names, emails, subjects and full messages. Every command and clipboard item uses an original menu icon.

Selection uses stable row occurrence IDs. Repeated Add entries retain their own selection while comparisons and clipboard output use real commit hashes. Format Patch follows Log's single/two-row selection rules and requires contiguous rows for larger selections. Busy, stale selection and bare-repository guards apply. Inspection remains available at a paused Edit; changing plan actions is disabled.

Notes reuse the native Log editor and refresh open Log views after saving. Exact UTF-8 note text is written as a blob and reused by Git notes, preserving blank lines, spaces, literal comment characters and empty notes even with Git 2.37, which lacks the newer --no-stripspace option.

Verification and remaining work

The headless native receiver hosts the actual Rebase view and invokes its actual menu dispatcher. It checks original icon resources, single/root/merge/two/repeated selections, busy/stale/bare guards, real unified-diff data, clipboard contents, notes saving without HEAD/index changes, and paused Edit inspection/Abort. Dialog and viewer handoffs are injected; clipboard checks use a private pasteboard.

This does not establish displayed menu positioning, keyboard accessibility, modal focus, signed sandbox execution or visual parity. Advanced upstream Log commands and further post-operation controls remain pending. Completed rows in custom sessions now remain visible and recover on reopening; see replay rows. See the dated QA record for test versions and build results.

Successful Rebase now exposes upstream completion commands through a native split control. Completion actions records direct and after-Fetch behavior, mail/export adaptation and remaining acceptance.
