* feat(protocol): define streamed diff revisions and resolve tag bases
* feat(server): stream shared diff revisions with paced file bodies
* feat(client): observe streamed diffs with atomic revision updates
* feat(app): show the Changes tree while diff bodies stream
* fix(server): retain the legacy structured diff payload budget
* fix(diff): preserve revision ordering and readable files
* fix(diff): select renamed patches and read dangling symlinks
* fix(diff): preserve nested checkouts and ambiguous patch paths
Only regular files and symlinks are readable untracked entries. Prefer patch metadata to ambiguous unquoted headers so paths containing a prefix delimiter keep their hunks.
* fix(diff): preserve BOM text and complete file replacements
Decode each string without consuming its leading BOM. File-type replacements emit multiple patch sections for one listed path, so retain all matching hunks. Assert the optional rename metadata in the existing commit-file journey.
* fix(diff): highlight symlinks from their stored target text
Working tree source context must match the symlink blob emitted by Git rather than the contents reached by following the link. Otherwise highlight runs do not cover the patch line and encoding fails the revision.
* fix(diff): tolerate disappearing highlight sources
Source context is optional after Git has produced the patch. Missing worktree link metadata must preserve the existing hunk-based highlighting fallback instead of failing the revision.
* fix(diff): batch cold reads and refresh logical comparison inputs
Acquire bounded pages of tracked patches lazily after Begin while retaining per-file highlighting and awaited frame delivery. Keep legacy preferred-base selection live across revisions and include submodule Git state in worktree cache identity.
* fix(diff): distinguish gitlink directories from replacements
A raw old gitlink mode also occurs when a submodule becomes a regular file. Query nested Git state only for a current directory, preserving normal file identity for replacements.
* fix(diff): invalidate timestamp-preserving file replacements
Size and modification time do not identify live file contents after a preserving copy. Include filesystem change time and file identity for tracked and untracked reuse, and verify live revisions agree with fresh reads.
* fix(diff): align highlight tokens with normalized patch lines
Git can normalize CRLF worktrees while highlighting reads their original line endings. Match tokens to the emitted patch text and trim only a normalization CR before encoding runs; mismatched source tokens are not attached.
* fix(diff): refresh equivalent worktree paths across platforms
Explicit refreshes must match filesystem-equivalent roots, including Windows path aliases. Use the existing realpath-aware matcher, budget real Git completion waits consistently, and assert optional status metadata in the filesystem commit-file journey.
* fix(diff): validate Git inputs and resolve refresh roots
Reuse now accounts for effective attributes, configuration, and canonical worktree blobs as well as filesystem state. Explicit refresh resolves repository identity like subscription creation, and callers await that resolution before acknowledging the command.
* fix(diff): keep non-Git workspace refresh successful
Diff invalidation has no target repository for an ordinary folder. Treat that expected absence as a no-op while preserving other root-resolution errors.
* fix(diff): observe scoped Git interpretation settings
Classify each metadata root with its worktree and common scopes, retaining both when the directories coincide. Shared attributes affect all checkouts, while config.worktree belongs to the owning checkout. Real subscriptions verify automatic binary and hunk-context refreshes in main and linked worktrees.
* fix(diff): observe interpretation inputs for pinned comparisons
Immutable commit objects still depend on mutable Git configuration and attributes. Declare those metadata inputs independently of ref, index, and worktree mutability, while keeping unrelated endpoint events out of pinned comparisons.
* fix(diff): observe interpretation independently of comparison endpoints
Commit comparisons still read worktree attributes. Watch those inputs independently, checking effective Git interpretation before invalidating fixed contents. Retain paths hidden by whitespace filtering so attribute changes can expose them. Forward binary frames through the branch-loading test interceptor.
The Changes view listed the same files in two different orders. The
tree rail put directories before files at each level of the path.
The scrolling diff compared the full path byte by byte. A root file
such as .gitlab-ci.yml therefore opened the diff, but sat below every
directory in the tree. Scrolling the diff did not walk the tree from
top to bottom.
Two sorts caused this. sortTree in git/diff-tree.ts sorted the tree.
compareCheckoutDiffPaths in git/diff-order.ts sorted the flat list at
ingest.
The tree is now the only ordering authority.
orderCheckoutDiffFiles builds the tree and reads the file sequence
back out of it. compareCheckoutDiffPaths is deleted, so the two
surfaces can no longer disagree.
The daemon keeps its own whole-path sort, so daemons that are not
updated also get this fix. Commit diffs keep the order that git
gives them, because that panel shows no tree rail.
Group changed files in the Changes view into a collapsible directory
tree instead of a flat list, on every form factor — consistent with the
Files explorer, which already renders a directory tree on mobile.
Folders are collapsible and expanded by default, single-child directory
chains are compressed into one row (packages/app/src), and folder rows
show aggregate +/- stats.
Client-only, built entirely from the existing ParsedDiffFile paths:
- diff-tree.ts: pure build/compress/flatten of the directory hierarchy,
keyed by full uncompressed dir path so collapse state survives
compression changes as the diff mutates.
- diff-flat-items.ts: pure buildDiffFlatItems + sumHeightsBefore. The
function retains a flat mode (showTree=false) as a tested seam for a
possible future flat/tree toggle; sticky header indices are
file-headers-only, derived from the post-collapse list.
- panel-store: diffCollapsedFoldersByWorkspace slice (collapsed-set, so
folders default to expanded), persisted via version 12. The set is
reconciled against the current diff so folders that leave and reappear
default to expanded and the stored set stays bounded.
Presentation primitives (chevron, indent guides, indent constant) are
extracted into components/tree-primitives and shared with the Files
explorer, which drops its private copies (and a banned useUnistyles
call site). The two trees now render identical rows; only the
tree-building stays separate (server listings vs. diff paths).
The toolbar's expand-all stays file-diffs-only (renamed
allFileDiffsExpanded); a separate control collapses/expands all folders.
