Problem

Symlinked files and directories are absent from the shared workspace index. In a project with src-link -> src and index-link.ts -> src/index.ts, typing @link or searching Files for link omits both aliases.

Change

Supplement the native index with eligible symlink entries discovered in indexed directories, without descending into their targets. Preserve alias paths and target kinds, apply ignore decisions, and merge aliases without duplicate results. Share discovery work, invalidate it on relevant watcher events, and page through all indexed directories. A bounded glob matcher applies .ignore rules without regex backtracking.

Verification

  • Reproduced in the real web dev app on Linux: composer mentions and Files search omitted file, directory and nested aliases; an ordinary-file control worked.
  • After merging current main, vp test run src/workspace/IgnorePatterns.test.ts src/workspace/WorkspaceEntries.test.ts src/workspace/WorkspaceSearchIndex.test.ts from apps/server: 34 passed. Tests cover real symlink discovery, exclusions and ignore precedence, matcher boundaries/adversarial inputs, watcher invalidation/subscription retry, shared scans, pagination and deduplication.
  • Targeted lint/format and server typecheck passed on the final correction; current main introduced no changes to these workspace files. git diff --check passed.
  • Malformed-class benchmark: parsing and matching 30,000 unmatched brackets took about 14 ms after the fix, versus 67.3 seconds with the previous matcher. The repository forbids wall-clock assertions in tests; the large-input regression checks behavior and these timings provide performance evidence.

Evidence compares main 909e4c9482 with head a3ebf4e7bd. Responsive web captures use Linux Chromium 154, DPR 2, 1440ร—900 and 390ร—900, light/dark. The recordings show alias discovery, insertion and opening the target file. The 390px captures cover responsive web.

The proof audit is insufficient: some unchanged controls differ in focus/selection, exact rebuild equivalence is unproven, and linked-image/lookup and remaining D1โ€“D6 matrix assertions are pending. No blanket pixel-identity claim is made. Fixture matrix.

Pending gates: independent review of the last matcher correction after the three-round cap; completion of the proof gaps above; CI and bot review. The bugfix label is withheld until CI is green and bot findings are addressed. No merge is authorized.

Unverified: Electron and native mobile execution, remote/relay/tunnel connections, command-palette/Markdown/icon-picker interactions and large-workspace latency/memory. Ordinary directory-scoped browsing is unchanged. Alias matching retains a known difference from the native fuzzy typo matcher.

Evidence: index, complete archive with captures, diffs, recordings and drivers. Individual upload failures are listed in the index; their files are retained in the archive.

Recordings include scripted query/insertion/opening steps; timings and rendering details are in the index. Diff0 is amplified 8ร—; threshold diffs mark RGB channel delta >16. Pixel-proof limitations remain as stated above.

A file search with limit: 1 can return no entries even when actual-file was fetched: if the watcher indexes the directory symlink src-link as a file, the native limit keeps src-link and actual-file is excluded, then this correction turns src-link into a directory and the file-kind filter drops it.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval โ€” This PR adds a substantial production symlink-discovery and ignore-rule pipeline to workspace listing/search, including filesystem scans, Git subprocesses, watcher caching, and a new static-analysis suppression. It also has unresolved high/medium correctness findings involving result limits, cache invalidation, and truncated ignore output.

Needs human approval because:

Walkthrough

The workspace search index now discovers eligible symlinks, applies .ignore and Git ignore rules, and includes links in listings and search results. New tests cover ignore-pattern matching, link filtering, watcher-driven refreshes, and directory scans.

Changes: Workspace symlink indexing

Layer / File(s)Summary
Ignore pattern parsing and matching
apps/server/src/workspace/IgnorePatterns.ts, apps/server/src/workspace/IgnorePatterns.test.ts
Adds ignore-pattern parsing and NFA matching for comments, negation, anchoring, glob syntax, escapes, and folder-only patterns. Patterns are evaluated from last to first. Tests cover matching behavior and edge cases.
Symlink discovery and filtering
apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceEntries.test.ts
Scans indexed directories for symlinks, resolves targets, and excludes links outside the workspace, inside .git, or with unsupported target types. Applies nested .ignore and repository Git ignore rules. Tests cover link inclusion and exclusion cases.
Listing, search, and scan cache
apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceSearchIndex.test.ts
Adds discovered links to listings and merges them into search results by match score. Caches scans while the watcher is active and the initial index is complete; tests cover watcher events, failed watcher registration, link kinds, and paginated directory scans.

Merge Risk: External image Moderate ยท up to a3ebf

The change makes symlinks searchable, but searches can repeat a full workspace scan after files are created or removed, or while indexing is still running. Large or busy workspaces may see slow mention and file search. Narrow the cache invalidation before merging, or accept the cost explicitly.

Explanation

The description includes the required Problem, Change, Scope and approval, and Verification sections. It explains the bug, implementation, linked issue, focused test results, limitations, and pending checks in sufficient detail.

Full details: Linked Issues check

Explanation

Issue #24547 requires symlinked files and directories to appear in the shared workspace index used by search and mentions. The PR scans indexed directories without descending into symlink targets, keeps supported in-workspace file and directory aliases, applies ignore rules, merges aliases into list and search results, and preserves target kinds. The added tests cover discovery, filtering, watcher refresh, pagination, and deduplication. These changes implement the issue's coding requirements.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #24547. IgnorePatterns.ts and its tests support the required ignore behavior. WorkspaceEntries.test.ts and WorkspaceSearchIndex.test.ts verify the symlink index behavior. The WorkspaceSearchIndex.ts changes implement discovery, filtering, caching, invalidation, pagination, and result merging. No unrelated product behavior is shown in the reviewed changes.

Avoid repeated full symlink scans before searches.

search() awaits listSymlinkEntries() before every fff query. The scan enumerates the root and every fff-indexed directory, then runs Git ignore checks for candidate links.

A created, removed, or renamed watcher event invalidates the cache. The next sequential search can therefore repeat the full scan. An incomplete fff index also invalidates the result, so searches made while fff is still scanning can repeat the scan. Concurrent callers share one in-flight scan, so this is not a separate scan for every overlapping keystroke. Ordinary modified events do not invalidate the cache.

Narrow invalidation to changes that can alter the symlink set, such as directory topology or ignore-file changes. Retain the last completed scan while fff is incomplete, or merge new results without discarding the completed cache. Do not run the symlink scan concurrently with the fff query unless the directory snapshot remains complete and consistent.
