Browse, view, edit and download workspace files from the web UI - #2
Shinigallo wants to merge 11 commits into
Conversation
Workspaces are only reachable from the host filesystem today — checking on what pi produced, tweaking a file by hand, or grabbing the finished project means shelling into the box or the container. Adds a "Files" view backed by a new /api/workspaces/:name/files|file|archive API: directory listing with breadcrumb navigation, a text editor for in-place edits, single-file download, and a .tar.gz download of the whole workspace (node_modules/.git/ etc. excluded). Path resolution rejects anything that escapes the workspace root. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds DELETE /api/workspaces/:name/file (recursive for folders, workspace root itself refused) plus a trash icon per row and on the open-file viewer, with a native confirm() before deleting — same pattern already used for sessions and skills elsewhere in the portal. Also fixes a bug found while testing: workspace selection seeded itself from the workspaces prop at mount time, which is empty until the parent's async fetch resolves. A full page reload (not just an in-app navigation) hit that empty state and never recovered, showing "Empty folder" instead of the workspace's contents. Now syncs once the list arrives.

its a nice idea but I think it will be better to have this as a side panel of the session page itself |

Merge Risk: 🟡 Moderate · up to The new file browser expands the portal to read, edit, and export workspace contents, but stale or out-of-order reads could save content into the wrong file or workspace, while concurrent file changes, interrupted saves, or failed archive generation could produce incorrect or incomplete results.

FilesPanel already had the state and handlers for opening, editing, and saving a file (openEntry, save, content, dirty, binary, fileError) plus an imported but unused Save icon — none of it was ever rendered. Clicking a file fetched its content into state with no visible effect, there was no way to edit or save through the UI, and the per-file download link (api.fileDownloadUrl) was defined but never called. Adds the editor pane: textarea bound to content/dirty, a Save button, a per-file download link, a binary-file fallback message, error display, and a confirm-guard against discarding unsaved changes when switching files or closing the panel.

Opening file B before file A's read had resolved let A's response land last and overwrite B's editor content, so a subsequent Save would write A's stale content to B's path. Tracks a request id per openEntry call; a read response (success or error) only updates state when it still belongs to the active request. Flagged by CodeRabbit on the previous commit.
Lexical checks (.., absolute overrides) never look at the filesystem, so a symlink inside a workspace pointing outside WORKSPACE_ROOT sailed through workspaceDir/resolveSafe untouched — list, read, write, and delete could all follow it out of the sandbox. Canonicalizes WORKSPACE_ROOT and every resolved target with realpath, walking up to the nearest existing ancestor for a target that doesn't exist yet (PUT creating a new file) so legitimate creates still work. A workspace directory that is itself a symlink escaping the root is now treated as not found, same as one that doesn't exist. Verified against a workspace containing a symlink to a directory outside the root: list/read/write through it now reject with "Path escapes the workspace", while listing the workspace and creating a genuinely new file still succeed. Flagged by CodeRabbit (CWE-59) on the original PR.

existsSync() follows symlinks, so it reports false for a dangling one — the ancestor walk in realpathThroughExistingAncestor then treated the link's own name as an ordinary missing path component, reconstructing a workspace-relative-looking path that passed the boundary check while writeFileSync followed the link itself to wherever it actually points. Walks with lstatSync instead, which sees the link as an existing entry regardless of where its target is. realpathSync on it then throws for a dangling target, which is now rejected explicitly instead of silently passed through. Verified with a dangling symlink workspace/link -> <outside>/created.txt: PUT now rejects with "Path escapes the workspace" and no file is created outside the workspace. Re-ran the prior symlink-escape and legit-new-file tests to confirm no regression. Flagged by CodeRabbit (CWE-59) on the previous commit.
