Rebase embedded history reference context

Pinned source: TortoiseGit 7338078f8ddd924b8cddee35f512f2286072136d. This is a partial workflow-family audit of IDD_REBASE, not completion of the Rebase resource or the application. The native surface is RebaseReplayTable and its RebaseWindowModel/RebaseWindowController owner.

Source and implementation

src/TortoiseProc/RebaseDlg.cpp:286,327–336: the embedded list suppresses ordinary HEAD font highlighting and removes Cherry Pick, Checkout revision, Reset, Revert, Merge, Rebase-to-version, Revert-to-version, Combine and Rollup from the shared menu mask. ID_SWITCHBRANCH remains permitted. Native controls keep that mask and additionally refuse mutation while a replay/owned child operation requires exclusive access.
src/TortoiseProc/GitLogListBase.cpp:1952–2082: Show Log uses the shared reference-or-extended-menu exception; Browse, Switch Branch, Create Branch, Create Tag, Export and Notes retain source order. Switch excludes the current full local ref; a pointed badge restricts the candidates. Multiple local refs produce a submenu. Current ref/HEAD are read under the existing cancellable column/reference operation, not guessed from a replay plan's branch field.
GitLogListBase.cpp:2093–2132: exactly two or a contiguous larger selection compares first/last displayed occurrences. Two occurrences expose both range directions, symmetric difference and ID_COMPARETWOCOMMITCHANGES. Native Compare dispatches actual occurrence endpoints, including repeated hashes.
GitLogListBase.cpp:2185–2226: Patch precedes Push. Push is present for a local-branch/tag-associated revision, or Shift's extended menu, with a pointed local/tag caption and source icon. SVN DCommit shares that gate and requires Git SVN plus a working tree. Pull requires the displayed HEAD and no merge. Bisect Good/Bad/Skip/Start follow active/marked/merge/selection gates and the same existing shared command preparation as Log; these are not replay actions.
GitLogListBase.cpp:2241–2285: Delete excludes the current ref, offers the pointed ref or a submenu and All. Rebase reuses LogWindowModel.deleteReferences and the Core reference-deletion snapshot, exact-object revalidation, remote choices, failure handling and cancellation. Its controller owns confirmation, failure and SSH sheets, inherits the parent's alpha, and resumes outstanding questions when forcibly retired. Busy/modal history actions block replay, editing, context menus, ordinary Close and Quit.
src/TortoiseProc/GitLogListAction.cpp:518–552,965–1007: Export guesses the first tag. Create Branch honors any pointed canonical ref, otherwise guesses the first remote to retain tracking; Create Tag uses the first remote guess. Push prefers the pointed local/tag, otherwise the first local branch then tag then hash; peeled tag markers are removed, and explicit refs disable preserved All Branches. Existing shared native request/Push helpers supply these handoffs.
Shared source DrawTagBranch/DrawTrackingRoundRect is represented by the existing LogReferenceTextField/LogReferenceTextCell: source palette roles, annotated tag tips, tracking links, symbolized names and optional labels on the right. Pointer hit testing and accessibility context actions use the actual clipped painter rectangles and full ref identity, never shortened label text. Rebase action backgrounds and current replay/Shift Find fonts are retained.
Clipboard's Tag/branch names entry calls the shared exact source-name formatter: pointed names use the source short form, unpointed copies retain full refs and CRLF. All items retain source artwork and the inherited context-icon preference.

Each popup owns its exact occurrence selection, form generation and full ref map. A native child/model state change invalidates the form generation, and a consumed popup cannot run another item. A reference refresh replaces the menu context. Repository refresh requests coalesce while an owned read, modal child or replay is busy and do not replace the draft replay plan. Deletion completion requests the same owned metadata refresh. Forced retirement cancels reads; global read and mutation accounting remains owned until the underlying work drains.

Grouped verification

The focused hidden receiver is qa/rebase-reference-context-native-2026-10-18.swift, RebaseReferenceContextVerification.verify(). Arguments are an owned private repository root and Git executable. It covers production painter geometry, pointed context menus, annotated tag/source colors, canonical local/remote/tag handoffs, Push persistence semantics, Switch current-branch exclusion, private clipboard text, stale/one-shot receipts, source menu order and Bisect gates, HEAD Pull, extended hash-only Push, contiguous Compare, real change-set viewer preferences, repeated-occurrence change-set/Bisect dispatch, and actual hidden Delete confirmation/refresh/Close/Quit ownership. HEAD/index are compared before/after; owned windows close and reads drain on both success and failure. Transport callbacks are injected to avoid external pushes, pulls or desktop windows; the local deletion uses only the private test repo.

Retained qa/rebase-history-tools-native-2026-10-18.swift covers Find duplicate occurrences/Shift highlight, history, ref failure sheets and cancellation drain, Export, range logs and containing-reference helpers. Grouped results are recorded in qa/history-reference-workflows-2026-10-18.json. These new assertions have not been run by the implementation agent; the parent owns the grouped checkpoint and the result record.

Remaining boundaries

Rebase supplies the selected occurrence count to the shared Log model for change-set/Bisect guards while preserving its ordered repeated entries. The ordinary Log default continues to use unique-hash selection. Equal-hash Bisect Start hands off the same source presets for review; it does not bypass Git's validation when the user later starts Bisect.
No physical Finder, signing/deployment, remote push/delete server, Git SVN installation, or every-dialog visual acceptance is established by this fixture. Shared remote deletion and Bisect Git behavior retain their existing Core coverage; this receiver checks their Rebase placement/gating and ownership.
Windows menus/flash cues, font metrics and shell rendering use macOS native equivalents. The retained Find status replaces Windows flashing/beeps.

Change-set comparison retains the source hash~1..hash command behavior, which can reject root commits. The successful native comparison fixture uses two parented commits and separately preserves repeated occurrences of one commit.
