Description

Ports the "multiple root folders" discovery feature from the Mikurunazume/Gamearr fork (see prior conversation) into Questarr, adapted to reuse this codebase's own conventions (IGDB client, title-utils, game_files/download-categorizer) instead of the fork's parallel implementations.

Lets a user point Questarr at extra directories on disk — an old library, a secondary drive, a GameVault-style flat folder — and scan them for games they already own but haven't imported yet. This is purely a discovery source: it's separate from the configured Library Root used by the download-import pipeline, and scanned games get a libraryPath pointing at their existing folder outside that root. The existing delete-game safety check already refuses to delete files outside the library root, so discovered folders are never touched by Questarr's own file management.

Surfaces as a new Discover tab under Settings → Import, next to Path Mappings.

Changes

  • shared/schema.ts — new root_folders table (path, name, enabled, health/disk stats) + migration
  • server/root-folders.ts — filesystem health probing (accessible, disk free/total)
  • server/library-scanner.ts — recursive scan of each root folder's top-level entries (dirs or standalone files), IGDB matching (auto-match above a similarity threshold, otherwise queued as "unmatched" for manual resolution), file records written into the existing game_files table
  • server/routes.ts — CRUD for root folders, scan trigger/status/unmatched-resolution endpoints, all behind authenticateToken
  • server/storage.tsRootFolder CRUD in both MemStorage and DatabaseStorage
  • server/middleware.tssanitizeRootFolderData/sanitizeRootFolderUpdateData
  • client/src/components/RootFolderDiscovery.tsx — add/manage root folders, trigger scans, live progress, resolve unmatched folders against IGDB candidates
  • docs/API.md, docs/ARCHITECTURE.md — documented the new endpoints and actor per those docs' own update policies

Type of change

  • New feature (non-breaking change which adds functionality)

Checklist

  • My code follows the style guidelines of this project
  • I have performed a self-review of my own code
  • I have commented my code, particularly in hard-to-understand areas
  • I have made corresponding changes to the documentation (docs/API.md, docs/ARCHITECTURE.md)
  • New actor/external interface — architecture and API docs updated accordingly (no new security-relevant surface beyond what FileBrowser/Library Root already expose to an authenticated user, so docs/SECURITY_ASSESSMENT.md wasn't touched)
  • I have added tests that prove my feature works (server/__tests__/root-folders.test.ts, server/__tests__/library-scanner.test.ts)
  • New and existing unit tests pass locally with my changes (npm run test:run: 2176 passed, 7 skipped; npm run check; npm run lint; npm run format:check)

Notes vs. the source fork

The fork's equivalent notification-connector dispatch skipped SSRF re-validation on outbound webhook calls at send time. This port carries no such gap — it makes no outbound network calls beyond the existing igdbClient (already going through the app's normal safeguards), and the fork's file-classification/root-folders UI (which was actually orphaned/unreachable in the fork's own HEAD) was rebuilt from scratch here as a reachable Settings tab.

Ports the multi-root-folder discovery feature from the Mikurunazume/Gamearr
fork, adapted to reuse Questarr's existing IGDB client, title-utils, and
game_files/download-categorizer conventions instead of introducing parallel
ones.

- shared/schema.ts: new `root_folders` table (path, name, enabled, health)
- server/root-folders.ts: filesystem health probing (accessible, disk stats)
- server/library-scanner.ts: recursive scan of each root folder's top-level
  entries, IGDB matching (auto-match above a similarity threshold, otherwise
  queued as "unmatched" for manual resolution), file records written into
  the existing game_files table
- server/routes.ts: CRUD for root folders, scan trigger/status/unmatched
  endpoints, all under authenticateToken
- server/storage.ts: RootFolder CRUD in both MemStorage and DatabaseStorage
- client: new "Discover" tab in Settings > Import (ImportSettings.tsx),
  backed by RootFolderDiscovery.tsx — add/manage root folders, trigger
  scans, watch progress, resolve unmatched folders against IGDB candidates

Matched games are created with `libraryPath` pointing at the discovered
folder outside the configured library root; the existing delete-game safety
check already refuses to delete files outside that root, so discovered
folders are never touched by Questarr's own file management.

Unlike the fork's notification-connector dispatch (which skipped SSRF
re-validation), this port has no outbound network calls beyond the existing
IGDB client, so that gap doesn't carry over.
- docs/API.md: new endpoint table for /api/root-folders and
  /api/library/scan*
- docs/ARCHITECTURE.md: add library-scanner.ts/root-folders.ts as a system
  actor (reads local filesystem directly, queries IGDB, writes storage)

📝 Walkthrough

Walkthrough

Adds configurable root folders for filesystem discovery. The server stores folder metadata, probes health, scans candidates, matches games through IGDB, tracks progress, and exposes authenticated APIs. The client adds controls for managing folders, scans, health, and unmatched results.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 4f175

This PR adds filesystem discovery, but the current implementation can leave matched games with incorrect library state, discard unresolved files when names collide, accept malformed scan requests, and allow authenticated users to alter shared discovery configuration and data. These correctness, data, and access-control risks should be fixed or explicitly accepted before merging.

Addresses CodeQL (3 high-severity path-injection alerts) and CodeRabbit
findings on PR #943:

- server/library-scanner.ts: matchUnmatchedFolder no longer joins the
  client-supplied folderName onto the root folder's filesystem path. It now
  resolves folderName against the server-trusted list of entries the scan
  itself already queued as unmatched, and rejects anything not in that list.
  This closes the path-traversal window CodeQL flagged (a folderName like
  "../../../etc" could previously make the server stat/scan arbitrary
  process-readable directories).
- server/library-scanner.ts: scanRootFolderById now guards against two
  concurrent scans of the same root folder racing on shared progress/
  unmatched state or duplicating filesystem/IGDB work.
- server/routes.ts: PATCH /api/root-folders/:id now re-probes the path when
  it changes, instead of persisting the new path while keeping health data
  from the old one.
- Added tests for the traversal rejection and the concurrency guard.

Not changed, with reasoning: CodeRabbit also flagged root_folders lacking a
user_id and getGameByIgdbId not being user-scoped. Both match this
codebase's existing conventions rather than being scanner-specific bugs —
indexers/downloaders are already global, unscoped config (not per-user),
and routes.ts already does a global getGameByIgdbId lookup elsewhere (the
download-claim flow) to dedupe games by igdbId across the whole instance.
Scoping just the scanner to per-user would make it inconsistent with the
rest of the app, not more correct. Also not renaming
RootFolderDiscovery.tsx to kebab-case — every existing component in
client/src/components is PascalCase.tsx; that's the actual convention here.

Pushed a fix for the CodeQL findings and the two data-integrity issues CodeRabbit flagged:

Fixed:

  • Path traversal (CodeQL, 3 high-severity alerts)matchUnmatchedFolder was joining the client-supplied folderName directly onto the root folder's filesystem path (path.join(rootFolder.path, folderName)), so a value like ../../../etc could make the server stat/scan an arbitrary process-readable directory. It now resolves folderName against the server-trusted list of entries the scan itself already queued as "unmatched", and rejects anything not in that list.
  • Concurrent scans of the same root folderscanRootFolderById now guards against two overlapping scans racing on shared progress/unmatched state or duplicating filesystem/IGDB work.
  • Stale health on path updatePATCH /api/root-folders/:id now re-probes accessibility/disk stats when path changes, instead of persisting the new path while keeping health data from the old one.
  • Added tests for the traversal rejection and the concurrency guard.

Not changed, with reasoning:

  • root_folders lacking a user_id — this matches the existing convention for indexers/downloaders, which are also global, unscoped instance config rather than per-user data. Scoping only the new table to users would make it inconsistent with the rest of the schema, not more correct, for what is documented as a self-hosted, typically single-or-few-user app (see docs/SECURITY_ASSESSMENT.md).
  • getGameByIgdbId not being user-scoped in the scannerroutes.ts already does the same global lookup elsewhere (the download-claim flow) to dedupe games by igdbId across the whole instance. The scanner following that existing pattern is intentional, not a new gap.
  • Renaming RootFolderDiscovery.tsx to kebab-case — every existing file in client/src/components is PascalCase.tsx; kebab-case isn't this codebase's actual convention.

CI should be green on the latest push; let me know if you'd like the two "not changed" items reconsidered.

Keep standalone entry identities unique.

Line 147 removes the extension from the entry identity. Game.iso and Game.zip in one root folder both become folderName === "Game". getUnmatchedEntry selects only the first entry, and clearUnmatched removes all entries with that name. Matching one file can therefore make the other file impossible to resolve.

Use an opaque entry ID or a unique relative path for lookup and clearing. Keep folderName only for display. Add a regression test for same-basename files.

The previous commit's CI run failed the "merge-test-reports" job: adding
library-scanner.ts (27% covered) and root-folders.ts pulled global coverage
just under the repo's enforced thresholds (81/74/77/82% for

- server/__tests__/library-scanner.test.ts: full scanRootFolderById run
  against a real temp directory — auto-match (new game), auto-match
  (existing non-owned game promoted to owned), weak-match unmatched queuing,
  skipping a folder with only ignored files, and category-by-parent-folder
  file assignment. Plus scanAllEnabledRootFolders.
- server/__tests__/root-folders.test.ts: refreshAllRootFoldersHealth against
  a mix of accessible/inaccessible folders.
- server/__tests__/storage.test.ts: root-folder CRUD coverage for

…complexity

Addresses the remaining CodeRabbit findings on PR #943:

- server/library-scanner.ts: standalone-file candidates (e.g. "Game.iso")
  now keep their extension as part of folderName instead of stripping it.
  Previously "Game.iso" and "Game.zip" in the same root folder both became
  folderName "Game", so getUnmatchedEntry could resolve the wrong file and
  clearUnmatched would drop both entries when only one was matched. Added a
  regression test covering same-basename files with different extensions.
- server/library-scanner.ts: extracted runScan's per-candidate body into
  processCandidate/recordMatchedCandidate/recordUnmatchedCandidate to bring
  its cognitive complexity under SonarCloud's threshold (was 18, limit 15),
  with identical progress-update ordering and no behavior change (covered
  by the existing full-scan test).
- server/middleware.ts, server/routes.ts: POST /api/library/scan and
  POST /api/library/scan/unmatched/match now validate their bodies with
  express-validator (sanitizeLibraryScanData, sanitizeUnmatchedMatchData) +
  validateRequest instead of manual type assertions, matching the rest of
  the codebase's route-validation convention.

Pushed another round addressing this review pass:

  • Fixed: standalone-file identity collision — Game.iso and Game.zip in the same root folder previously both became folderName === "Game" after extension-stripping, so resolving one via matchUnmatchedFolder could clear the other's queued entry too. Standalone candidates now keep their extension as part of the identity. Added a regression test for this exact scenario.
  • Fixed: POST /api/library/scan and POST /api/library/scan/unmatched/match now validate their request bodies with express-validator + validateRequest, matching the rest of the codebase's route-validation convention, instead of manual type assertions.
  • Fixed: runScan's cognitive complexity (SonarCloud flagged 18 vs. limit 15) — extracted the per-candidate logic into processCandidate/recordMatchedCandidate/recordUnmatchedCandidate, same behavior, covered by the existing full-scan test.
  • Also fixed a CI failure from the previous push: adding these files dropped global test coverage just under the repo's enforced thresholds, so I added coverage for the scan happy-path, health-refresh, and root-folder storage CRUD.

Also pushed back to green after CodeQL/coverage were red on the prior commit — CI should be clean now.

Parse both scan payloads with shared Zod schemas.

sanitizeLibraryScanData and sanitizeUnmatchedMatchData provide express-validator checks, but the handlers use TypeScript assertions. Those assertions do not validate runtime input before the handlers call storage and scanner services.

Add shared Zod schemas and parse req.body after validateRequest.

The coverage-fix commit passed thresholds locally by a very thin margin
(as little as 0.04pp on functions) and still failed CI's merge-test-reports
job, so this adds more real coverage to leave headroom instead of retrying
the same thin margin:

- server/__tests__/library-scanner.test.ts: exercise igdbToInsertGame's
  optional-field mapping (cover, screenshots, platforms, genres,
  involved_companies) via a fuller IGDB mock response, and the "file
  already tracked" skip branch in assignFilesToGame. Also address
  CodeRabbit's nitpick that scanAllEnabledRootFolders' test only covered a
  single folder — now asserts both of two enabled folders complete.
- server/__tests__/database_storage_integration.test.ts: root-folder CRUD
  against a real in-memory SQLite DB (DatabaseStorage), not just MemStorage.

Local coverage margins now 0.89/0.85/0.86/1.0 percentage points above the
81/74/77/82% thresholds, up from as low as 0.04pp before.
…verage

Addresses the remaining CodeRabbit finding and the Codecov patch-coverage
gap on PR #943:

- server/library-scanner.ts: when a scan re-matches an existing game (via
  scanRootFolderById's auto-match or matchUnmatchedFolder's manual
  resolution), the existing-game branch previously only flipped status to
  "owned" — a game with no libraryPath yet (e.g. added manually or from a
  wishlist, never imported) stayed pathless even though its folder was just
  found. It now also sets libraryPath, but only when the game doesn't
  already have one, so an existing managed path is never clobbered. Added
  tests for both the "gets set" and "stays preserved" cases.
- client/__tests__/RootFolderDiscovery.test.tsx: new RTL test suite for the
  Discover tab component, mirroring the existing PathMappingSettings.test.tsx
  pattern (empty state, rendering folders/health, add/delete/toggle, scan
  trigger, unmatched-entry resolution). This component previously had 0%
  patch coverage per Codecov's report on this PR, unlike its sibling
  settings components which already have RTL tests.
- client/src/components/RootFolderDiscovery.tsx: renamed the "Add Folder"
  dialog submit button to "Add Root Folder" — it previously shared its
  accessible name with the dialog's trigger button, which is both an a11y
  smell and made it impossible to target the submit button unambiguously
  in tests.

Coverage margins now comfortably clear the repo's thresholds
(82.34/75.25/78.77/83.46% vs. 81/74/77/82%).

Pushed another round:

  • Fixed: a real correctness bug — when a scan re-matched an existing game (auto-match or manual unmatched resolution), it only flipped status to owned and left libraryPath untouched. A game with no path yet (added manually, from a wishlist, never imported) stayed pathless even though its folder was just found. Now it sets libraryPath when the game doesn't already have one, without ever overwriting an already-managed path. Added tests for both cases.
  • Fixed: Codecov's patch-coverage failure (51% vs. 65% target) — RootFolderDiscovery.tsx had 0% patch coverage. Added an RTL test suite for it mirroring the existing PathMappingSettings.test.tsx pattern (empty state, rendering, add/delete/toggle, scan trigger, unmatched-entry resolution). While doing that I also fixed a real a11y/testability issue it surfaced: the dialog's submit button shared its accessible name ("Add Folder") with the trigger button — renamed to "Add Root Folder".
  • Not changed: CodeRabbit's suggestion to add Zod-schema parsing on top of the express-validator checks already added last round — sanitizeLibraryScanData/sanitizeUnmatchedMatchData already reject malformed input at the route boundary (type coercion via .toInt(), length bounds, non-empty checks) before the handler runs, so the type assertion after validateRequest is safe. A parallel Zod schema would duplicate that validation, not add coverage it's missing.

Root-folder-discovered games live outside the configured library root,
so the existing "delete game with files" flow always skipped removing
their files. Add an allowDelete flag (default false) on root_folders
that, when explicitly enabled, lets that same delete flow remove files
under that specific folder too.

- shared/schema.ts: add allowDelete column + migration
- server/root-folders.ts: isWithinDeletableRootFolder() checks whether
  a resolved target path sits inside an allowDelete:true root folder
- server/routes.ts: DELETE /api/games/:id now allows deletion when the
  path is inside the library root OR an opted-in root folder
- server/middleware.ts: validate allowDelete as boolean on create/update
- client: RootFolderDiscovery gets an "Allow Delete" toggle per folder,
  with a confirmation toast when turning it on
- Tests across storage (Mem + DB), routes, root-folders, and the React
  component
- docs/API.md, docs/SECURITY_ASSESSMENT.md updated

Discovery/scanning itself remains read-only regardless of this setting.

Added the requested opt-in delete authorization for root folders, and merged main into this branch to resolve the conflict from recently-merged PRs.

New: per-root-folder "Allow Delete"

  • root_folders.allow_delete (new column, migration 0030), default false
  • DELETE /api/games/:id?deleteFiles=true now also removes files when the game's libraryPath resolves inside a root folder that has allowDelete: true — previously any path outside the configured Library Root was unconditionally skipped, so discovered games' files could never be deleted this way even if the user wanted that
  • Off by default and scoped per-folder (not global) — discovery/scanning itself stays entirely read-only regardless of this setting
  • New "Allow Delete" toggle column in the Discover tab's folder table, with a confirmation toast when turning it on
  • docs/API.md updated (also fixed a pre-existing doc/behavior mismatch: the DELETE endpoint actually returns 200 { success, fileDeletion }, not 204)
  • docs/SECURITY_ASSESSMENT.md — added a risk-register row for this capability expansion, since it's a genuine (if opt-in, off-by-default) widening of what the delete flow can remove from disk

Merge with main

  • Resolved two conflicts (shared/schema.ts, server/__tests__/fixtures/common-route-mocks.ts) — both were non-overlapping additions from each side, kept both
  • Re-ran full validation post-merge: tsc --noEmit clean, lint/format:check clean, vitest run --coverage → 2266 passed / 7 skipped, coverage 82.93/75.62/79.42/84.08% (statements/branches/functions/lines), comfortably above the 81/74/77/82% gate
