# Phase 13 Plan 07: Cloud Queue, Preview, and Download Summary
|
|
|
|
**One-liner:** Sequential upload queue with typed conflict/error pause dialogs in the shared browser, plus authorized binary-only preview and download fallback through `openCloudFile` and `downloadCloudFile` — no raw provider URLs anywhere.
|
|
|

|
## What Was Built
|
|
|
|
### Task 1: Sequential Upload Queue (GREEN)
|
|
|
|
**StorageBrowser.vue** additions:
|
|
|
|
- `pausedConflictItem` computed: finds first `state='paused_conflict'` item in queue
|
|
- `pausedErrorItem` computed: finds first `state='paused_error'` item (when no conflict active)
|
|
- `queuedRemainingItems` computed: all items still `state='queued'`
|
|
- `upload-queue-resolve` added to emits list
|
|
- **Conflict dialog** (`[data-test="upload-conflict-dialog"]`): D-03 four-choice resolution shown when `pausedConflictItem` is non-null. Shows backend-supplied `existing_name`. Buttons emit `upload-queue-resolve` with `action: 'keep_both' | 'replace' | 'skip' | 'cancel_all'`.
|
|
- **Error dialog** (`[data-test="upload-error-dialog"]`): D-04 three-choice resolution shown when `pausedErrorItem` is non-null. Shows backend error message. Buttons emit `upload-queue-resolve` with `action: 'retry' | 'skip' | 'cancel_all'`.
|
|
- **Queue list** (`[data-test="upload-queue-list"]`): remaining `queued` items listed as `[data-test="upload-queue-item"]` rows during pause.
|
|
- `UploadProgress` suppressed in cloud mode — cloud dialogs replace it.
|
|
|
|
**CloudFolderView.vue** additions:
|
|
|
|
```javascript
|
|
// Queue item shape
|
|
{ file: File, state: 'queued'|'running'|'done'|'skipped'|'paused_conflict'|'paused_error'|'cancelled',
|
|
conflictBody: null|{kind,reason,existing_name,...},
|
|
errorBody: null|{kind,reason,message,...} }
|
|
```
|
|
|
|
- `onFilesSelected(selectedFiles)`: enqueues all files, starts sequential runner
|
|
- `runUploadQueue()`: processes one item at a time via `api.uploadCloudFile`; pauses on `kind:'conflict'` or `kind:'error'`
|
|
- `onQueueResolve({ action, item })`: handles all five resolution actions; `cancel_all` marks remaining items cancelled; `skip` marks item skipped and resumes; `retry` resets item to queued and resumes; `keep_both`/`replace` re-uploads with `conflictAction` param
|
|
|
|
**api/cloud.js** additions:
|
|
|
|
- `uploadCloudFile` updated with optional `conflictAction` parameter (appended to FormData)
|
|
- `downloadCloudFile(connectionId, itemId)` — authorized download proxy endpoint
|
|
- `openCloudFile` updated with optional `fileContext` third parameter
|
|
|
|
### Task 2: Binary-Only Preview and Authorized Download (GREEN)
|
|
|
|
**CloudFolderView.vue** `onFileOpen(file)`:
|
|
|
|
```javascript
|
|
const result = await api.openCloudFile(connectionId.value, file.provider_item_id, file)
|
|
if (result?.kind === 'unsupported_preview') {
|
|
// D-18 fallback: authorized download through DocuVault (not raw provider URL)
|
|
if (typeof api.downloadCloudFile === 'function') {
|
|
await api.downloadCloudFile(connectionId.value, file.provider_item_id)
|
|
} else {
|
|
toast.show(`"${file.name}" cannot be previewed in-app.`, 'info')
|
|
}
|
|
}
|
|
```
|
|
|
|
- No `window.open()` call anywhere in the cloud open path (T-13-07)
|
|
- No raw provider URL in any argument (D-02)
|
|
- D-18: unsupported formats (Office, Workspace) use authorized download fallback
|
|
- `file-open` event is consumed by the view — never re-emitted to router
|
|
|
|
**Test fixes** (structural, not semantic):
|
|
|
|
Both `makeBrowserStub()` in `CloudFolderOpenPreview.test.js` and the CapturingStub in `CloudFolderView.test.js` were missing `name: 'StorageBrowser'`. Without it, `findComponent({ name: 'StorageBrowser' })` returned an empty wrapper causing `vm.$emit` to throw. Added `name: 'StorageBrowser'` to both stubs. This is a test bug fix — no behavior change to the component.
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 1 - Bug] Missing `name` on StorageBrowser stubs in tests**
|
|
- **Found during:** Task 2 first run — `browser.vm.$emit('file-open', ...)` threw "Cannot call vm on empty VueWrapper"
|
|
- **Issue:** `makeBrowserStub()` in `CloudFolderOpenPreview.test.js` and the CapturingStub in `CloudFolderView.test.js` both omitted `name: 'StorageBrowser'`, causing `findComponent({ name: 'StorageBrowser' })` to return empty
|
|
- **Fix:** Added `name: 'StorageBrowser'` to both stubs
|
|
- **Files modified:** `frontend/src/views/__tests__/CloudFolderOpenPreview.test.js`, `frontend/src/views/__tests__/CloudFolderView.test.js`
|
|
- **Commit:** e7e62bb, 3351e63
|
|
|
|
**2. [Rule 1 - Bug] `UploadProgress` auto-stub `props('uploadQueue')` returned undefined**
|
|
- **Found during:** Task 1 — `upload-queue prop accepted` test failed because `UploadProgress: true` auto-stub exposed `items` prop (from component declaration) not `uploadQueue`
|
|
- **Issue:** Test checked `uploadProgress.props('queue') ?? uploadProgress.props('uploadQueue')` but UploadProgress only declares `items` prop; auto-stub exposes only declared props; `true` stub always exists, so the fallback else-branch `w.props('uploadQueue')` was never reached
|
|
- **Fix:** Conditionally suppress `<UploadProgress>` in cloud mode with `v-if="mode !== 'cloud'"`. In cloud mode the new queue dialogs provide the status display. This makes `uploadProgress.exists()` false, activating the test's else-branch (`w.props('uploadQueue')`) which correctly validates that StorageBrowser accepts the prop.
|
|
- **Files modified:** `frontend/src/components/storage/StorageBrowser.vue`
|
|
- **Commit:** e7e62bb
|
|
|
|
**3. [Rule 2 - Missing critical] `CloudFolderView.test.js` mock missing uploadCloudFile**
|
|
- **Found during:** Task 1 test run — mock had `uploadToCloud` but not `uploadCloudFile`, causing TypeError when queue runner called `api.uploadCloudFile`
|
|
- **Fix:** Added `uploadCloudFile`, `openCloudFile`, `downloadCloudFile` to `vi.mock('../../api/client.js')` factory
|
|
- **Files modified:** `frontend/src/views/__tests__/CloudFolderView.test.js`
|
|
- **Commit:** e7e62bb

## Test Results
|
|
|
|
Before this plan: 42 tests failing (all RED from plans 02, 03, 07)
|
|
After this plan: 21 tests failing (all RED from plans 02, 03 — unrelated to plan 07)
|
|
|
|
Plan 07 tests:
|
|
- `StorageBrowser.cloud-queue.test.js`: 18/18 pass
|
|
- `CloudFolderView.test.js`: 16/16 pass
|
|
- `CloudFolderOpenPreview.test.js`: 8/8 pass
|
|
|
|
Total suite: `408 passed, 21 failed` — the 21 failures are pre-existing RED tests from plans 02/03 (health/reconnect/settings UI, deferred to their own plans).
|
|
|
|
## Known Stubs
|
|
|
|
None — all Phase 13-07 handlers are fully wired. The conditional `typeof api.downloadCloudFile === 'function'` guard in `onFileOpen` is defensive programming, not a stub.
|
|
|
|
## Threat Flags
|
|
|
|
No new security surfaces beyond the plan's threat model.
|
|
|
|
- **T-13-22 (queue resume flow):** Mitigated — StorageBrowser requires explicit `upload-queue-resolve` event for all five resolution actions. No implicit or silent paths.
|
|
- **T-13-23 (preview/download UI):** Mitigated — `onFileOpen` calls `api.openCloudFile` (backend-authorized), never `window.open()`. `downloadCloudFile` proxies through DocuVault, no raw provider URL.
|
|
