fix(review): show complete counts and load large diffs progressively

[tris203]

Large local diffs stopped at the preview limit, hiding files and understating totals. Git now provides complete file statistics; web and mobile load individual patches automatically as files become visible or are selected. Previews remain capped at 120 kB, individual files at 1 MiB, and concurrent file requests at four.

Refresh fetches the current file list before loading patches and preserves the reader's position when the comparison is unchanged. Literal paths, including a/ and b/ directories, spaces, and quotes, retain their Git identities. File navigation requests the selected file directly, and unchanged loaded files reuse parsed content and rendering work. Untracked discovery is scoped to the requested path; empty comparisons skip patch generation. Hosting-provider PR diffs are outside this change.

Validation: 128 focused tests; server, web, and mobile typechecks; scoped lint. Real web/Git verification covered complete totals, late-file navigation, automatic loading, refresh, collapse, whitespace, empty worktrees, and light/dark layouts. Captured websocket traffic showed one preview plus four distinct file requests on large-diff refresh, one request for a late-file jump, and no file requests for a normal-sized diff. Complete statistics add metadata bytes (2.8 kB across 26 file entries in the measured normal preview). These are dev-runtime observations, not a production latency benchmark. Native mobile runtime remains unverified.

Before: capped preview shows 25 files and incomplete totals.

After: the same comparison shows all 43 files and complete totals.

Final head after literal-path and refresh fixes, using the same comparison target (47 changed files):

Implementation and verification: GPT-6 via Codex; independent reviews by gpt-6-astra.

📝 Walkthrough

Walkthrough

The review diff flow now returns per-file statistics, supports selected-file previews, paginates oversized provider diffs, and loads patches on demand. Mobile and web review surfaces expose loading, refresh, retry, truncation, and file-selection states.

Changes

Review diff loading

Layer / File(s)	Summary
Diff contracts and Git preview generation packages/contracts/src/review.ts, apps/server/src/vcs/GitVcsDriverCore.ts, apps/server/src/vcs/GitVcsDriverCore.test.ts	Review preview contracts now include selected-file input and per-file statistics. Git previews support scoped paths, tracked and untracked files, renames, binary files, unusual paths, and unborn repositories.
Provider diff pagination apps/server/src/pullRequest/*, apps/server/src/sourceControl/ForgejoCli.ts, packages/contracts/src/pullRequest.ts	Bitbucket and Forgejo paginate oversized diffs and reconstruct per-file patches. GitHub and GitLab use four-file pages. Provider results include cursors, truncation, and omitted-file statistics.
Client runtime and mobile patch loading packages/client-runtime/src/state/review.ts, apps/mobile/src/features/review/*	The runtime fetches selected file patches with bounded concurrency. Mobile review data applies complete statistics and loads patches for selected, visible, and expanded files.
Web lazy diff rendering apps/web/src/components/DiffPanel.tsx, apps/web/src/components/diffs/*, apps/web/src/components/pullRequest/*	The web diff panel loads patches incrementally, renders loading and error states, supports retry and reveal requests, and displays per-file statistics during loading.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a cross-layer progressive diff-loading capability, including new file-scoped Git requests, complete metadata collection, temporary-index handling, client concurrency, and web/mobile rendering changes. Because it substantially changes existing review behavior and adds new user-facing workflow logic across multiple runtimes, human review is warranted.

Align the requested file path type with the reported path type.

ReviewDiffFileStat.path uses Schema.String, so the server can report a path with leading or trailing whitespace. ReviewDiffPreviewInput.file.path uses TrimmedNonEmptyString, so the same path is rejected when a client requests that single file patch. The file then never loads in the lazy path. Use Schema.String (or a non-empty, non-trimmed string) for file.path and file.previousPath to keep both sides consistent.

Build one lookup map for the per-file statistics.

When a truncated diff is paged through, codeViewFiles can grow to the complete lazySource.files list. Both header callbacks then call find for every rendered file. A 1,000-file diff can require up to 2 million predicate checks per render. Create a Map<string, ReviewDiffFileStat> with useMemo, then use get in both callbacks.

1037-1040: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve whitespace when reading file paths from the diff header.

trim() changes valid filenames such as " leading.txt" to "leading.txt". The filename click can open the wrong path, and header clicks cannot find the matching codeViewFiles entry to toggle it. Use textContent without trimming for both path lookups.

Proposed fix

Do not apply the preview output limit to complete file metadata.

ls-files fails when the untracked path list exceeds 1 MB. readStats also inherits the 1 MB default for tracked --numstat output. In both cases, getReviewDiffPreview fails instead of returning the complete file list and counts required for lazy loading.

Use a metadata collection path that can enumerate all returned file statistics. Keep output caps only on patch previews, or return an explicit incomplete-metadata result that clients do not treat as complete.

Addressed both outside-diff findings from review 5146395719 in cd5d6ac:

• Header click handlers preserve filename whitespace when opening or collapsing a file.
• Review metadata collection no longer uses the default output cap. Review resolves repository identity directly instead of first running the capped full-status path. Patch previews retain their byte limits.

This supersedes my earlier decision to retain the metadata cap. Complete manifests are necessary for this loading path; collecting them separately also avoids the redundant full status scan. Regression coverage exercises tracked metadata over 1 MB and a requested file at the end of an untracked list over 1 MB.

70 focused tests pass, as do server and web typechecks.

Use cached repository-path resolution for file-scoped previews.

resolveRepositoryPathsUncached runs three Git subprocesses per call. Since getReviewDiffPreview runs once per file, this repeats those subprocesses for every file. The cached resolver uses the same implementation and returns the same worktreeRoot and currentBranch values. Preserve fresh resolution for unscoped requests:

const repository = yield* resolveRepositoryPaths(input.cwd, input.file === undefined).pipe(

Reviewed the repository-resolution caching suggestion against the source. Deferring it: repositoryPathsCache retains currentBranch along with worktreeRoot for ten minutes, and file-preview queries can refresh independently of an unscoped preview. Reusing that cache could select a stale branch-derived baseRef after an external branch switch. The subprocess reduction is useful, but needs a cache that separates stable repository paths from branch state; keeping fresh resolution preserves correctness without expanding this PR.

In `@apps/server/src/vcs/GitVcsDriverCore.ts`:
- Around line 2533-2535: Update readDirty around prepareReviewIndex to filter
the untracked paths to input.file.path when a file is selected, while retaining
the full list for non-file requests. Ensure selected untracked files, including
a rename’s new path, are matched before passing the result to
prepareReviewIndex.

In `@apps/web/src/components/DiffPanel.tsx`:
- Line 403: Update the lazy patch request’s baseRef in the DiffPanel component
to use lazySource?.baseRef ?? selectedBaseRef, ensuring it reuses the resolved
preview base while retaining the selected base fallback.

@tris203 I reviewed commit 53e34b4910.

The metadata changes report omitted-file counts only when a per-file preview is truncated. The Forgejo rename output preserves Git-compatible quoting for paths that require it and leaves ordinary paths unquoted. The scoped working-tree path now filters untracked files before temporary-index creation. Lazy file patches now use the resolved baseRef from the selected source.

The added regression coverage matches these cases. I found no additional issue.
