fix(files): browse ignored files and load folders on demand by maria-rcks · Pull Request #11527 · pingdotgg/t3code

maria-rcks · 2026-09-13T04:49:46Z

the file explorer excluded gitignored files and stopped listing after 25,000 entries. web, desktop's shared web client, and mobile now request each folder's immediate children as it opens, display ignored entries dimmed, and browse without a workspace-wide cap. search remains bounded, and web breadcrumbs use the same folder listing.

verified through the web client: ignored folder expansion and file preview, workspace search in unopened folders, breadcrumb sibling navigation, recursive expand/collapse, failed-folder retry, and deletion refresh. blacksmith: 66 focused tests passed, including a 26,000-file workspace; contracts, server, web, and mobile typechecks passed; scoped lint passed. native mobile interaction remains unverified because this host has no usable emulator or installed development client.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a new filesystem/VCS-backed lazy browsing capability across web and mobile, while changing the existing file tree’s loading and default expansion behavior. The cross-cutting production impact and changed product default warrant human review.

📝 Walkthrough

Walkthrough

The change adds direct directory listing APIs, lazy directory-loading hooks, ignored-entry metadata, and updated web and mobile file browsers. It also adds directory error mapping, search truncation handling, expansion state changes, and server coverage.

Changes

File tree loading

Layer / File(s)	Summary
Workspace directory listing contract `packages/contracts/src/project.ts`, `apps/server/src/workspace/WorkspaceEntries.ts`, `apps/server/src/ws.ts`, `apps/server/src/workspace/WorkspaceEntries.test.ts`	Workspace listings accept `directoryPath`, return ignored metadata, reject invalid paths, map directory-read failures, and preserve complete large-directory results.
Web directory data loading `apps/web/src/components/files/projectFilesQueryState.ts`, `apps/web/src/components/files/useDirectoryEntries.ts`, `apps/web/src/state/queries.ts`	Web hooks cache directory results, limit concurrent loads to four, refresh reachable directories, flatten cached entries, and expose search truncation.
Web file browser integration `apps/web/src/components/files/FileBrowserPanel.tsx`, `apps/web/src/components/files/FileBreadcrumbs.tsx`	The web file browser uses lazy directory loading and path search. It updates expansion, refresh, error, loading, truncation, breadcrumb, and ignored-entry behavior.
Mobile file browser integration `apps/mobile/src/features/files/useFileTreeEntries.ts`, `apps/mobile/src/features/files/fileTree.ts`, `apps/mobile/src/features/files/FileTreeBrowser.tsx`, `apps/mobile/src/features/files/ThreadFilesRouteScreen.tsx`, `apps/mobile/src/features/files/thread-file-navigator-pane.tsx`	Mobile file trees use debounced search, cached directory loading, recursive snapshot merging, ignored-node metadata, selected-path expansion, and directory status callbacks.

Merge Risk: ⚪ Minimal · up to 00b45

The file browser receives a fresh directory cache when the workspace target changes, so no current merge-blocking risk remains.

Upstream's "browse ignored files and load folders on demand" (pingdotgg#11527) implements what fix/file-tree-large-workspaces carried here: reading a workspace one directory at a time on web and on mobile, and searching the whole workspace from the tree's search field. It reaches the same place by a different route, adding an optional directoryPath to projects.listEntries rather than a second RPC beside it, and it browses ignored files as well. Carrying both would leave a duplicate of an upstream feature across the contracts, the server and both clients, and every later upstream change to the file tree would conflict with it. So the fork's implementation goes and upstream's stands on its own: - projects.listDirectory, out of the contracts, the RPC group, the IPC surface, the client-runtime atom family, the authorization scopes and the server. - d3PagedFileTree, d3ProjectDirectoryQueryState, D3WorkspaceSearchResults and fileTreeDirectories on web; useWorkspaceFileTree, workspaceFileTree and d3FileTreeSearch on mobile, with their tests. - The symlink, permission and ordering handling in WorkspaceEntries, the partly scanned search index in WorkspaceSearchIndex, and the indexStatus these reported through. The fork's own tests for that work go with it; upstream covers the same ground in WorkspaceEntries.test.ts. What is kept is the mobile file tree's header inset, which is a separate fix and unrelated to any of this: the header overlays the list on every iOS version, so the inset is calculated on all of them and applied by hand where the system does not apply it.
