What Changed

Resolves #997

Files inside initialized Git submodules now show up in workspace search (@ mentions, file listing, and content search), even in repos that keep nested worktrees next to their submodules.

Upstream's fff-node index already walks into initialized submodules and applies each submodule's .gitignore. Two gaps kept submodule files out of results anyway:

  1. .git/info/exclude is not honored. fff applies .gitignore files but not .git/info/exclude or core.excludesFile. Tools often hide nested git worktrees there. In one affected repo, a .worktrees/ folder excluded only through info/exclude added over 100k files to the index. That pushed the submodule contents past the 25k entry cap, and copies inside the worktrees outranked the real files in search.
  2. Submodule gitlink files are listed. Each submodule's .git pointer file (for example vendor/sub/.git) appeared as a searchable file.

This PR, all in workspace/WorkspaceSearchIndex.ts:

  • Loads excluded directories and exact files from Git at index creation and refresh, including configured core.excludesFile files named .gitignore. File, directory, and mixed searches apply root-anchored native constraints before pagination; same-named nested paths stay searchable.
  • Excludes submodule .git pointer files. Mixed queries ending in / retain directory-only behavior.
  • Keeps content-query parsing, literal fallback, escapes, and overlapping whole-word matches intact. Single plain tokens use separate native constraints where compatible; the original grep paths filter excluded results while continuing pagination.

Tests in workspace/WorkspaceEntries.test.ts:

  • A real initialized submodule: its tracked and untracked files are indexed, its .git pointer file is not, and its own .gitignore is applied.
  • Folders hidden by .git/info/exclude are left out of search, list, and content search, while a nested folder with the same name is kept. This test fails without the fix.

Why

Users expect files in a checked-out submodule to be searchable like any other workspace file. Excluding paths through .git/info/exclude is standard git behavior, and ignoring it lets unrelated nested checkouts crowd out real workspace files.

Note

Add initialized git submodule files to workspace search results

  • Adds listInitializedGitSubmodulePaths to discover initialized submodules via git submodule foreach --quiet pwd, resolving paths relative to cwd and filtering invalid entries.
  • Adds listGitWorkspaceFilePaths to recursively list tracked and untracked files across the root repo and all initialized submodules, respecting per-repo .gitignore rules and excluding submodule root paths from file results.
  • Updates buildWorkspaceIndexFromGit to use the new recursive listing; submodule roots are now treated as directories derived from their file descendants rather than as files.
  • Propagates truncation flags across all recursive submodule listings so the workspace index truncated flag is set correctly.
  • Caps parallel submodule scans at 8 (GIT_SUBMODULE_SCAN_CONCURRENCY).

takeover verification

vp run check:changed github/main passed on blacksmith: format, lint, knip, graphql, typechecks, and 29 tests. existing regression cases reproduce all five corrected query regressions. real chrome client and authenticated websocket checks covered initialized submodule files, git exclusions, directory-only search, regex, literal fallback, overlapping whole words, and escaped patterns.

current search interactions on the final head

previous before/after captures and provider verification remain in the takeover verification comment. native desktop/mobile, windows/macos, relay/tunnel, and large-workload performance remain unverified.

model: gpt-6.1-sol; harness: codex in t3 code.

- recurse through initialized git submodules when building git-backed workspace indexes
- include tracked and untracked files from initialized submodules in workspace search results
- exclude parent repo gitlink entries so submodule roots are indexed as directories, not files
- propagate truncation state across recursive submodule scans
- add regression coverage for submodule indexing and refresh the generated MSW worker asset

Walkthrough

Workspace search now loads Git exclusion information and applies constraints to listing, entry search, and content search. Tests cover initialized submodules, excluded paths, constraint-like literal queries, and behavior when Git is unavailable.

Changes: Workspace search behavior

Layer / File(s) Summary
Load and classify Git exclusion constraints
apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceEntries.test.ts, apps/server/src/workspace/WorkspaceSearchIndex.test.ts
The index discovers ignored directories and classifies their exclusion source. Git command failures produce no additional excluded directories. Tests isolate Git operations and cover submodule contents and excluded paths.
Apply exclusions to path searches
apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceSearchIndex.test.ts
The index applies discovered-directory and .git constraints to listing and path searches. It reloads excluded directories after refresh. Tests cover the .git constraint and unavailable Git.
Apply exclusions to content searches
apps/server/src/workspace/WorkspaceSearchIndex.ts, apps/server/src/workspace/WorkspaceSearchIndex.test.ts, apps/server/src/workspace/WorkspaceEntries.test.ts
Content search selects multiGrep or grep based on query shape and filters matches under excluded paths. Tests cover pagination and constraint-like queries treated as literal text.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: maria-rcks

Merge Risk: Moderate · up to 786dc

Files excluded individually through .git/info/exclude can still appear in workspace search, and directory-only searches can include files. Correct these behaviors before merging unless the limitations are explicitly accepted.

Full details: Out of Scope Changes check

Explanation

The changes remain within workspace search. WorkspaceSearchIndex.ts handles Git exclusions, submodule gitlink entries, and content-search filtering. The workspace tests cover submodule indexing, .git/info/exclude, literal constraint-like queries, and pagination behavior. The VCS environment setup and search mock updates support these tests. No unrelated change is shown.

Full details: Description check

Explanation

The description clearly explains the problem, changes, affected behavior, tests, observed results, limitations, and agent details. It does not use the template headings exactly and does not provide explicit maintainer approval evidence under Scope and approval, but the required technical information is mostly complete.

Upstream replaced the git ls-files workspace indexer (workspaceEntries.ts)
with the fff-node FileFinder index, which already walks initialized
submodules and honors their .gitignore. Drop the branch's git-based
submodule enumeration along with the deleted module, and instead filter
the submodule `.git` gitlink file out of index entries. Port the
regression coverage to workspace/WorkspaceEntries.test.ts.

fff-node applies .gitignore files but not .git/info/exclude or
core.excludesFile. Repos that hide nested worktrees there had their
index flooded (100k+ files), pushing initialized submodule files past
the 25k entry cap and below worktree copies in search ranking.

Load the directories git excludes through those sources when an index
is created or refreshed and append them as root-anchored `!dir/**`
constraints to every file, directory, mixed, and grep query.

Filtering `.git` gitlink entries after fff paginated could shorten a
results page and misreport truncation. Exclude them with a `!**/.git`
query constraint so fff drops them before ranking and pagination.
Glob-form constraints also keep mixed search returning files, so the
list/search special cases for constraint-only queries are gone.

Add an untracked, non-ignored submodule file to the submodule test as a
positive control for the ignore assertion.

Git hooks export GIT_DIR, GIT_INDEX_FILE and related variables. The
fixture helper inherited them, so commands like the submodule test's
commit could target the caller's repository. Unset repository-location
variables for every fixture git command.

fff treats a single-token grep query as the pattern but parses
constraint syntax (`src/`, `*.ts`, `!x`) once other tokens follow.
Appending exclusion constraints turned such queries into filters, so
searching for `src/` or `!important` returned nothing.

Single plain tokens now go through multiGrep, whose separate
`constraints` field keeps exclusions native. Single regex tokens run
unconstrained, as upstream, and drop excluded paths from results.
Multi-token queries, which fff already parses, are unchanged.

Exclusion discovery kept only collapsed `dir/` entries, so file rules in
.git/info/exclude or core.excludesFile left those files searchable.
Keep excluded file paths too and constrain each as `!{path,}`: a bare
slash-free glob matches at any depth and grep ignores `!{path}`, while
the empty alternative stays exact in every search mode. The content
search post-filter matches files exactly as well.

takeover update for 9d7b4cb8d9aba024e993b9e3e8b12d70789b978f:

merged current main without rebasing. kept main's refresh timeout handling and the exclusion reload. fixed five verified search regressions: directory-only mixed queries, global excludes files named .gitignore, multi-token literal fallback, overlapping whole-word matches, and escaped plain queries. each failed first in existing regression cases; no new test files.

blacksmith vp run check:changed github/main passed format, lint, both knip steps, graphql, typechecks, and 29 tests. both independent read-only reviewers found the final sha merge-ready. the diff remains three files.

rechecked the real linux web client with chrome and a real initialized submodule. content search returns tracked and untracked submodule files, hides git-excluded files, preserves literal fallback, and highlights the valid overlapping whole-word match. authenticated browser websocket requests also confirmed directory-only results, regex, escaped newline, and escaped glob queries. the replay provider supplied only the thread shell; search results came from the real filesystem and server. no paid provider turn was rerun in this pass; the previous provider verification is retained below.

current submodule, literal fallback, and whole-word searches in chrome

native desktop/mobile, windows/macos, relay/tunnel, large-workload performance, and arbitrary ignore patterns remain unverified.


previous verification on the pre-merge head:

Verified in a real dev environment

verified unchanged head 3e0689bde526907961cfc5d2f31f7efae5f2a9f0 on linux with the real dev web app, repository Playwright, and /usr/bin/google-chrome. reproduced the bug first on github/main (8b74a69019) in a separate worktree. only one dev server ran at a time.

a project was created through the app. a real codex gpt-6.1-sol turn created its git repo, initialized submodule, tracked/untracked files, and exclusion rules. both revisions searched that same repo. on the pr, selecting the submodule file mention and sending it to codex produced the exact file contents through a real provider tool call.

  • main returned the submodule .git pointer in file mentions and four paths hidden by .git/info/exclude in content search. the pr excludes all five.
  • tracked and untracked submodule files remain searchable; the submodule's ignored generated file stays out. same-named nested src/build, src/secret.env, and src/lib/creds.txt remain visible.
  • file picker and content-search results open the actual submodule file in the editor.
  • literal src/, *.ts, and !important, regex need.e, and multi-token needle token searches still work.
  • a further real provider turn configured local core.excludesFile. the hidden marker returned zero results, and the visible control returned one. refreshed websocket listing/content queries agreed.

short runtime transcript from the authenticated browser's websocket API:

main UI: needle -> 10 matches, including four excluded paths
pr projects.listEntries -> 21 entries, truncated=false; no gitlink or excluded paths
pr projects.searchEntries(kind=directory) -> 8 directories, truncated=false
pr projects.searchContents(needle) -> 6 expected matches, truncated=false
pr content search(src/ | *.ts | !important) -> lib/notes.txt for each
pr content search(need.e, regex=true) -> 6 expected matches
pr content search(needle token) -> src/secret.env, src/lib/creds.txt
pr after core.excludesFile update: hidden marker -> 0; visible marker -> 1
blacksmith: vp test run apps/server/src/workspace/WorkspaceEntries.test.ts apps/server/src/workspace/WorkspaceSearchIndex.test.ts
27 tests passed across 2 files

before, main with matching repository data:

main content search includes four git-excluded paths

after, exact pr head:

pr content search keeps six expected matches and excludes hidden paths

submodule mention selection and content-search result opening in the real app

real codex response and actual submodule file open in the editor

captures inspected; uploaded mp4 playback and seeking checked in chrome. the recording is embedded here as a gif because github does not render external mp4 image embeds.

Not verified

native desktop shell, ios/android, macos/windows, remote/relay connections, other providers, and the reported 100k-file workload were not exercised on this linux vm. whitespace/glob-special exclusion paths and excluded files inside wholly untracked directories were not exercised. this verifies the concrete flows above, not every git-ignore pattern or performance at scale.
