feat(stack-files): force-text override for misidentified binary files (#1215)
* feat(stack-files): force-text override for misidentified binary files
The binary-detection heuristic (30% non-printable / NUL in the first
8 KB) sometimes flags UTF-8 files that happen to carry an embedded NUL
or a high non-printable ratio, locking the user out of inline editing
with only a Download fallback.
readStackFile now accepts an optional { forceText: true } that bypasses
isBinaryBuffer on the small-file path and returns the bytes as UTF-8
content. The route exposes this as ?force=text on GET /files/content.
The oversized branch deliberately stays untouched: returning a multi-MB
file as JSON-encoded text is wasteful regardless of the heuristic.
SpecialFilePanel grows an optional extraAction slot. The viewer's
binary branch wires Open as text anyway, which refetches with the new
flag, clears isBinary, and routes the content through the existing
Monaco editor path. A failed override surfaces both an inline error
panel and a toast so the user knows why the click did nothing.
Backend tests pin the heuristic-vs-override behaviour pair on a file
with a literal NUL byte. The frontend test asserts that the second
readStackFile call carries forceText: true and that Monaco mounts.
Troubleshooting accordion entry updated to mention the new affordance.
* fix(stack-files): guard the binary-override path against oversized files
The override on the binary panel could open Monaco against an empty
content buffer if the backend's oversized branch ran (files past the
2 MB inline-preview cap intentionally carry no content even when
force=text is set). Saving that empty buffer would wipe the file on
disk.
Two reinforcing changes:
- Initial load now checks result.oversized before result.binary, so a
file that is both oversized and has binary bytes in the 8 KB probe
shows the Download panel rather than the binary panel. The size
signal stays in front of the operator and the override button never
surfaces for a file that cannot be safely opened inline.
- The handleForceText handler now respects result.oversized on the
refetch and transitions to the Download panel instead of clearing
isBinary and copying result.content ?? '' into Monaco.
Same handler also gains a stale-request guard via a selectedPathRef:
a slow override for file A no longer stomps on file B's state if the
user navigated away while the request was in flight.
Two regression tests pin the new behaviour: oversized+binary surfaces
the Download panel on initial load, and an oversized refetch from the
binary panel routes to the Download panel rather than Monaco.

fix(stack-files): optimistic concurrency on file-tab writes via mtime ETag (#1206)
* fix(stack-files): optimistic concurrency on file-tab writes via mtime ETag PUT /api/stacks/:name/files/content previously did a blind write; two operators editing the same script lost one of the saves with no warning. The compose-file editor already had mtime optimistic concurrency (PR #1183); this brings the file-explorer write path to the same shape. GET /files/content now also returns mtimeMs and sets a weak ETag header derived from the stat. The matching PUT reads If-Match, asks FileSystemService.writeStackFileIfUnchanged to compare against the live mtime, and returns 412 PRECONDITION_FAILED with the current content and mtime when the stale-write check fails. Successful writes echo a fresh ETag so the client can pin the next save without re-GET. readStackFile and writeStackFileIfUnchanged each open the file once and stat+read through the same handle so the mtime returned to the client matches the bytes that were sent, even if the file is replaced between the two operations. PUT without If-Match still succeeds (backward compatibility with scripted clients that do not roundtrip the ETag). FileViewer now sends the loaded mtime on save, updates its local mtime from the success response, and on FileConflictError adopts the server snapshot as the new baseline so the user's follow-up edit-and-save does not loop on the same precondition. * fix(stack-files): treat deleted-target as conflict; preserve user buffer on conflict Two follow-ups from code review on the prior commit: - writeStackFileIfUnchanged now returns ok:false when expectedMtimeMs is set and the target has been deleted. The caller was editing a file that no longer exists; silently writing the buffer to the void is wrong. The client adopts the empty snapshot as 'file is gone, start over' and the user keeps control of what to save next. - The FileViewer conflict handler no longer overwrites the user's typed buffer with the server snapshot. It updates the baseline so the next save sends the fresh mtime, then leaves the editor content alone. The user sees their edits, the Save button stays enabled, and a follow-up click applies their changes on top of the new server version without silently destroying what they typed. * fix(api): preserve default headers when caller supplies a headers field apiFetch built defaultOptions.headers by merging Content-Type, x-node-id, and the caller's headers, but then spread the unmodified fetchOptions over defaultOptions at the outer level. The spread overwrote the merged headers with the caller's bare headers, silently dropping Content-Type on every request that supplied any custom header. This was latent until the file-explorer save path started sending an If-Match header. The Express body parser refused the PUT without Content-Type, the route returned 400, the editor showed an error toast instead of the success toast, and the Playwright save assertion timed out. Destructure headers out of fetchOptions before the outer spread so the already-merged defaultOptions.headers survives. Add api.test.ts with four regression cases pinning Content-Type, the If-Match merge, x-node-id presence when active, and localOnly skip. |

fix(stack-files): confirm before overwriting an existing upload target (#1204)
* fix(stack-files): confirm before overwriting an existing upload target Same-name uploads previously truncated the existing file silently. A user dragging a file with a name that matched an in-place file destroyed the original with no warning and no undo. The upload route now reads ?overwrite=0|1. When the flag is not set and the target already exists, the server returns 409 FILE_EXISTS and the original file is untouched. The frontend opens a confirm dialog and retries with overwrite=1 on the user's approval; cancel keeps the original. A new pathExists helper on FileSystemService performs the existence check through the same path-resolution barrier as the write so a malicious relPath cannot bypass the conflict check. UploadConflictError is exported so callers can distinguish the conflict case from generic upload failures without parsing error strings. * fix(stack-files): distinct DIR_EXISTS code, drop INVALID_PATH swallow in existence check |

chore(stack-files): client-side path-traversal guard in stackFilesApi (#1190)
The backend already rejects path-traversal attempts through isValidRelativeStackPath, so the server side is safe today. Adding a client-side mirror is defense-in-depth: it shortens the failure loop (no wasted round trip) and protects against a future server-side regression that loosens validation. Adds isClientSafeRelPath in frontend/src/lib/stackFilesApi.ts mirroring the backend predicate (rejects absolute paths, drive letters, backslashes, NUL bytes, double slashes, and any segment that is `.` or `..`). Wraps every export that accepts a relPath / targetDir / fromRel / toRel argument with assertSafeRelPath, throwing a clear Error before the fetch is issued. 12 unit tests cover the predicate (POSIX accepts, traversal rejects, Windows drive letters, backslashes, NUL bytes, non-string inputs). Frontend suite stays at 288/288. |

feat(files): per-stack file explorer (#780)
* feat(files): backend foundation for stack file explorer
Install multer for multipart file upload handling. Add
isValidRelativeStackPath to validation.ts to guard client-supplied
relative paths against traversal, absolute paths, NUL bytes, backslash
injection, and double-slash segments. Add isBinaryBuffer to a new
binaryDetect.ts utility for heuristic text/binary detection via
NUL-byte fast exit and non-printable byte ratio sampling.
* fix(files): reject bare dot segments in isValidRelativeStackPath
* feat(files): add safe stack-scoped file I/O methods to FileSystemService
Adds FileEntry interface and seven new public methods to FileSystemService
for stack-scoped file operations: listStackDirectory, readStackFile,
streamStackFile, writeStackFile, deleteStackPath, mkdirStackPath, and
statStackEntry.
Each method routes through a private resolveSafeStackPath helper that
enforces two-phase path containment: a pre-realpath lexical check plus a
post-realpath symlink-escape check. ENOENT targets are handled by walking
up to the deepest existing ancestor, realpaths that ancestor, and
reattaching the remaining suffix.
Binary detection delegates to isBinaryBuffer; path safety delegates to
isPathWithinBase. Protected file names and the MIME map are module-level
constants to avoid repeated allocation.
* feat(files): frontend API wrappers and Monaco language helper
* fix(files): tighten stackFilesApi error handling and localOnly support
* fix(files): FileSystemService safety and correctness fixes
* feat(files): add file explorer API endpoints to stacks router
* feat(files): FileTree and FileTreeNode components
* fix(files): route security hardening and stream cleanup
* fix(files): FileTree accessibility, icon stroke, stale fetch guard
Add strokeWidth={1.5} to all Lucide icons in FileTreeNode to match the
design system. Add aria-expanded to directory rows for accessibility.
Guard handleDirClick .then() callbacks against stale stack name
references when the component re-renders with a new stack. Add
toast.info fallbacks when compose.yaml or .env is clicked without a
navigation callback registered.
* feat(files): FileViewer, FileUploadDropzone, NewFolderDialog, DeleteFileConfirm
* fix(files): resolve code quality findings in file explorer components
- Move editorOptions useMemo above conditional returns in FileViewer (Rules of Hooks fix)
- Fix blob download: append anchor to DOM before click, defer URL revoke 100ms
- Keep protected-file confirm input visible during NOT_EMPTY recursive retry in DeleteFileConfirm
- Remove non-functional cursor-pointer/onClick from Community upgrade pill in FileUploadDropzone
- Add success toast on folder creation in NewFolderDialog
- Switch all (e as Error).message casts to instanceof Error narrowing
* test(files): unit tests for binary detection, stack path safety, and file explorer routes
- binary-detection.test.ts: covers isBinaryBuffer edge cases (empty, NUL,
PNG header, threshold boundary, sampleBytes parameter)
- filesystem-stack-paths.test.ts: covers isValidRelativeStackPath (accepts/
rejects matrix) and FileSystemService stack methods against a real temp dir
(listStackDirectory sort and protection flags, readStackFile text/binary/
oversized paths, writeStackFile/Buffer, deleteStackPath, mkdirStackPath,
traversal guard); platform-specific empty-dir/NOT_EMPTY cases skip on Windows
- stack-files-routes.test.ts: route-level integration tests for all seven
file explorer endpoints; covers auth gating, Community-tier 403 gates,
input validation, 413 TOO_LARGE upload limit, and 204/200 happy paths
* feat(files): StackFileExplorer container with lazy tree, viewer, and action bar
* fix(files): add Download button to explorer toolbar, fix Community upgrade pill, reset state on stack change
* test(files): add missing test coverage for file explorer routes and service
* feat(files): add Files tab to EditorLayout with StackFileExplorer integration
* fix(files): add defensive activeTab guard to saveFile and discardChanges
* test(files): unit tests for FileTree expand/collapse and FileViewer render modes
Covers the three FileViewer content modes (text/Monaco, binary panel,
oversized panel) and the FileTree expand/collapse/cache cycle: first
expand fetches the subdirectory, second click collapses without a fetch,
third click re-expands from the in-memory cache without a second fetch.
* test(e2e): file explorer community and skipper+ flows
Covers the full file-explorer feature surface in two describe blocks:
Community (read-only): intercepts /api/license to simulate community
tier, confirms the upgrade pill is visible in the left pane, and
asserts that the Save button is absent after opening a text file.
Skipper+ (full CRUD): uploads a text file and confirms it appears in
the tree; edits config/app.conf and saves via Monaco; deletes an
uploaded file and asserts the tree entry is gone; issues a raw HTTP
request to the download endpoint and checks for status 200 and the
content-disposition: attachment header.
Also adds data-testid="file-action-delete" to the action bar Delete
button in StackFileExplorer for stable targeting, and exports
waitForStacksLoaded from e2e/helpers.ts to eliminate the three
identical local copies in stacks, deploy-log-panel, and stack-files
spec files.
* fix(e2e): improve test isolation and selector stability in stack-files spec
Move beforeEach seed to beforeAll/afterAll so fixtures are created once per
suite, not before every test. Extract shared seedSuite/teardownSuite helpers
to eliminate the duplicate beforeAll/afterAll blocks. Wrap teardown in
try/catch so failures log a warning rather than masking test results.
Replace waitForTimeout(500) with a deterministic expect on the file tree
sentinel. Add data-testid="anatomy-files-btn" and data-testid="delete-confirm-btn"
to replace the fragile button text/positional selectors. Assert Save button
starts disabled before editing.
* docs(files): add stack file explorer documentation
Add user-facing guide for the stack file explorer feature covering
tier access (Community read-only, Skipper+ read-write), viewing
limits, upload/download caps, protected file routing, and
troubleshooting. Update the editor page to reference the new guide
and register the page in the navigation.
* fix(docs): use canonical Skipper tier name in file explorer overview card
* fix(files): resolve lint errors blocking CI
Remove unnecessary backslash escape before double-quote in the
Content-Disposition regex (no-useless-escape). Replace five synchronous
setState resets at the top of the FileTree mount effect with a React key
prop on the FileTree element in StackFileExplorer so remounting resets
state automatically, eliminating the react-hooks/set-state-in-effect
violation.
* test(files): fix e2e seeding to work on community-tier CI
Replace the browser-side paid upload/mkdir API calls in seedTestStack with
direct Node fs writes. The upload and folder endpoints require Skipper+ so
they returned 403 on CI, which runs with no license set. Stack creation
via POST /api/stacks stays as an API call since it is community-allowed and
keeps the backend registry in sync.
Add a per-test tier check in the Skipper+ beforeEach that skips gracefully
when the instance is community, matching the pattern in auto-heal-policies.
