Cause: WorkspaceEntries.listIgnoredFiles sorts git's ignored-file list and slices it to 200, and ProjectListIgnoredFilesInput only accepted cwd, so no client input could reach files sorting after the 200th. Fix (follows maintainer PR #24795's design): ProjectListIgnoredFilesInput gains an optional query (TrimmedString, max 256), and the server filters paths by case-insensitive substring before the cap. A new ignoredFileSearch capability flag tells clients the server honors it, so older servers keep the old picker instead of showing a search that silently does nothing. In AddProjectToMachineDialog a search field appears only when the unfiltered listing is truncated (debounced 150 ms; Enter does not submit the clone). Selection is now a path-to-file map, so picks survive across searches and selected bytes stay accurate. Selections are capped at 200 (COPIED_FILES_MAX_COUNT, the same as the listing limit), so the reachable copy count does not grow; the 1 MiB per-file limit is unchanged. One deviation from #24795: the header counter keeps its original 'N of M' wording when the list is not truncated and only becomes 'N selected' when it is, so projects with 200 or fewer ignored files see no visible change. The search field, the 'Search to find the rest.' hint, the 'No ignored files match.' empty state and the 'Up to 200 files can be copied.' note only appear in the truncated case. No new regex or parser; the filter is String.includes on lowercased paths, linear in the git output, which is already capped at 4 MiB. The two-server browser flow was not rerun here; #24795 verified the same server change and nearly identical dialog code end to end. Web only: mobile has no ignored-file picker.

Fixes #24504

Reproduction on main

Commit 1a1f9ac (origin/main). Built a Git fixture with an HTTPS origin and 204 tracked folders pkg-001..pkg-204, each holding an ignored build.log, plus zz-config/.env.local (ignored, sorts last), for 205 eligible ignored files. Started env A with T3CODE_DEV_SEED=0 vp run dev and env B with node apps/server/src/bin.ts serve --port 38991 --base-dir <scratch>, both on fresh databases. Added the fixture project to env A with t3 project add. In the web client: Settings > Connections > Environments > Add environment with env B's pairing URL (Connected). Opened a new thread in the fixture project, then Run context menu > Add to another machine > env B. The dialog listed pkg-001/build.log through pkg-200/build.log with the note 'Showing the first 200 files.' Its only text input is the destination folder: no search, no paging. zz-config/.env.local was not anywhere in the dialog, so it cannot be selected.

Evidence

Being captured: before and after in the real app. This section is filled in before the pull request can merge.

Tests

vp test run src/workspace/WorkspaceEntries.test.ts -t 'past the listing limit' with main's WorkspaceEntries.ts: 1 failed (the result held the first 200 files, not file-205). vp test run src/workspace/WorkspaceEntries.test.ts with the fix: 28 passed. vp run check:changed: pass (format, lint, knip, graphql, typecheck 37 packages, tests 6 files / 52 passed, react compiler).

Not in this change

  • No server-side cap on how many files the clone flow copies; the 200-file selection cap is enforced only in the client, as before.
  • Selected file sizes are snapshots from the listing that showed them and are not refreshed if a file changes while the dialog is open.
  • Open maintainer PR fix(web): find ignored files past the copy picker cutoff #24795 covers the same bug; whichever lands, the other should be closed.

AI-assisted; verified with the tests and tools listed above.

Add to another machine listed only the first 200 ignored files in path
order, so a file sorting after them could never be selected.
projects.listIgnoredFiles now takes an optional path query and filters
before the cap, and the dialog shows a search field when the listing is
truncated. Selections persist across searches and stay capped at 200.
The ignoredFileSearch capability keeps older servers on the old picker.

Walkthrough

The listing contract and server now support query filtering before the 200-file limit. The dialog adds debounced search, retains selections across results, and enforces a 200-file selection limit.

Changes: Ignored-file search and selection

Layer / File(s) Summary
Query contract and server filtering
packages/contracts/src/project.ts, packages/contracts/src/environment.ts, apps/server/src/environment/ServerEnvironment.ts, apps/server/src/workspace/WorkspaceEntries.ts, apps/server/src/workspace/WorkspaceEntries.test.ts
The listing input accepts an optional query, and the server advertises search support and filters matching paths before applying the listing limit. A test checks that a matching file beyond the first 200 candidates is returned without truncation.
Dialog search and retained selections
apps/web/src/components/AddProjectToMachineDialog.tsx
When search is supported, the dialog debounces queries and displays matching results. It retains selected file records across results and submits their paths.
Selection limits and controls
apps/web/src/lib/addProjectToMachine.ts, apps/web/src/components/AddProjectToMachineDialog.tsx
The dialog caps selections at 200 files. Row and bulk controls respect the limit, and default selections contain eligible file records.

Merge Risk: Minimal · up to ed8bd

The change lets users search ignored files beyond the first 200 in the "Add to another machine" dialog, and servers without the capability keep the existing picker. No concrete merge-blocking risk was found in the changed code.

Full details: Title check

Explanation

The title names the web fix and its user-visible effect: ignored files past the copy picker cutoff can now be found. It matches the main change (server-side query filtering before the 200-file cap, plus the search field in AddProjectToMachineDialog). It is a conventional commit title in plain language. It does not cover the capability flag or selection-map changes, which is acceptable.

Full details: Linked Issues check

Explanation

Issue #24504 has one active coding objective: users must find and select eligible ignored files beyond the first 200 candidates in the web "Add to another machine" dialog. Limits of 200 selected files and 1 MiB per file must remain.

Evidence at head ed8bdcc:

  • Server: WorkspaceEntries.listIgnoredFiles (apps/server/src/workspace/WorkspaceEntries.ts) now filters Git-reported paths by a case-insensitive substring query before the .toSorted() and 200-file cap. Inspected diff confirms this ordering.
  • Contract: ProjectListIgnoredFilesInput (packages/contracts/src/project.ts) adds optional query (TrimmedString, max 256). Inspected diff confirms this.
  • Capability: ExecutionEnvironmentCapabilities gains ignoredFileSearch, advertised as true in ServerEnvironment.make. The dialog uses it to gate the search field, so older servers keep the old picker.
  • Client (per PR summary, not directly inspected): search field appears only when the unfiltered listing is truncated; 150 ms debounce; path-keyed selection map persists across searches; selection capped by COPIED_FILES_MAX_COUNT = 200; 1 MiB per-file limit unchanged.
  • Test (per PR summary): new test queries FILE-205, which sorts past the limit, and expects its path with truncated: false. The author reports the test failed on main and passed with the fix (28 tests in file).

The objective is addressed by this PR alone. No stack membership was supplied, so no stack objective applies. The dialog behavior rests on the PR summary and the author's report, not on a direct inspection of AddProjectToMachineDialog.tsx. The two-server browser flow was not rerun. This is a verification gap, not a missing requirement.

Full details: Out of Scope Changes check

Explanation

All changed areas support the #24504 objective:

  • Server filter before cap (WorkspaceEntries.ts) and its regression test.
  • Optional query input and ignoredFileSearch capability (contracts, ServerEnvironment.ts). The capability gates the new UI for older servers.
  • Dialog search, debounce, path-keyed selection map, and capped selection (AddProjectToMachineDialog.tsx).
  • COPIED_FILES_MAX_COUNT constant (addProjectToMachine.ts). It keeps the existing 200 limit explicit.

The header wording change ('N of M' kept when not truncated) and the conditional hint, empty state, and note are UI details that serve the same dialog. They do not add a copy capability or change copy limits. Nothing in the reviewed summaries is unrelated to the issue. The PR description's 'Evidence' section is still a placeholder. That is a process item, not a code change, and it does not affect scope.

Full details: Description check

Explanation

The description follows the template sections: Problem (cause and expected behavior), Change (query input, capability flag, dialog search, selection map, 200-file cap), Scope (links issue #24504 and references maintainer PR #24795), and Verification (specific test commands and results). It also includes a reproduction on main. The Evidence section is a placeholder that says screenshots are being captured and the section must be filled before merge. The description also lacks the required 'Verification' statement about the browser flow not being rerun, which it does state. The missing before/after UI screenshots are required for UI changes by the template, so the description is not fully complete.

Resolution

Replace the placeholder under 'Evidence' with the before and after screenshots of the Add to another machine dialog, as the template requires for UI changes. Upload them to GitHub and embed or link them in the Verification section. Remove the note that says the section is being captured.

Thanks for this. #24795 makes the same change and is the one being kept.

Both changes implement the same search-before-cutoff fix, but #24795 includes completed evidence of searching and copying files between two real environments. This PR still leaves that evidence unfinished, so the existing change is the better one to carry forward.

Preserving the original counter wording for untruncated lists is a useful refinement that can be carried into the retained change without maintaining a second implementation.

Closing as a duplicate.
