[PB-4449]: refactor/upload task follows each upload on its own by xabg2 · Pull Request #2325 · internxt/drive-web

xabg2 · 2026-11-12T10:25:47Z

Description

Each upload task now follows its own file or folder from start to finish: it decides by itself when it ends and with which status, however many times what failed in it is retried.
A retry goes into the same queue as the rest of the upload, so retrying while other folders are still uploading never runs more than 6 uploads at the same time.
The user can retry a failed file while the rest of its folder is still uploading; the folder only finishes once its retries do.
Retrying everything while one failed item is already being retried now queues the rest too, and still uploads nothing twice.
A folder completed thanks to a retry is still counted as a folder upload, and cancelling a folder still removes what was created without hiding a failed removal.
Not used by the app yet: the next PRs share one queue across uploads and move the Drive uploads onto it.

Testing Process

Upload tests for a folder ending with its failed items listed, retrying while another folder is still uploading without going over 6 uploads, retrying a failed file while its folder is still uploading, retrying everything while one item is already being retried, and a file saving its upload state as in process when it starts. Typecheck, lint and the upload and tasks tests pass.

Summary by CodeRabbit

Bug Fixes
- Retrying a failed file no longer blocks retries of other failed uploads, including uploads in concurrently transferring folders.
- A file that finishes uploading just after cancellation is now reported as successful.
- Cancelling a retry of an already-uploaded folder no longer removes that folder.
- Folder upload status now reflects partial failures more accurately.
Improvements
- Upload tasks maintain consistent status and progress across retries.
- Cancelling a folder upload removes the created folder when possible; removal failures are reflected in the task status.

Walkthrough

Upload now uses a persistent manager and per-item trackers to handle file and folder task state, failures, completion, cancellation, and retries. Tests cover persisted task state, cancellation outcomes, and retry coordination during concurrent uploads.

Changes: Upload tracking

Layer / File(s)	Summary
Tracker lifecycle and failure records `src/app/upload/tracker/UploadTracker.ts`, `src/app/upload/tracker/FailureList.ts`	The base tracker manages upload events, task state, failure records, retry selection, reporting, and completion. `FailureList` stores failed records and selects eligible items for retry.
File and folder task tracking `src/app/upload/tracker/FileUploadTracker.ts`, `src/app/upload/tracker/FolderUploadTracker.ts`	The file tracker manages file task state and handles completion after cancellation when an upload UUID exists. The folder tracker tracks progress and handles cancellation and removal of a created folder.
Manager integration and retry validation `src/app/upload/Upload.ts`, `src/app/upload/Upload.test.ts`, `src/testUtils/fixtures/upload.fixtures.ts`	`Upload` forwards manager events to trackers and delegates cancellation and retries. Tests cover persisted task state, cancellation, retry coordination, and concurrency limits. The fixture helper creates folders with files.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: Minimal · previous review 6d464

The new upload tracker flow is not yet wired into the app, and the earlier concerns about success-after-cancel, removal-callback error classification and the concurrency test are fixed at the current head. Remaining edge cases around folder cancellation and persistence ordering are minor and unconfirmed, so merge risk is minimal.

Full details: Title check

Explanation

The title names a refactor where each upload task follows its own file or folder upload, including retries. The changeset adds per-item trackers (UploadTracker, FileUploadTracker, FolderUploadTracker), a FailureList, and a persistent UploadManager, which matches the main change. The title is brief but uses the ticket prefix and a slightly awkward phrasing ('refactor/upload task follows each upload on its own'). It is clear enough for a teammate scanning history.

Full details: Description check

Explanation

The description states what each upload task now does, how retries share the six-upload queue, how folders wait for retries, and how a retry-all action behaves. It also notes the change is not yet used by the app and lists a dependency. It includes a testing process section. Related Issues is marked N/A, and the Related Pull Requests entry is free text rather than the requested link format. Several checklist items remain unchecked (local testing, documentation, SonarCloud, QA), which is acceptable because those are non-critical for this check. The description is mostly complete.

If a folder finished with one failed file and the user cancels while retrying it, this deletes the whole folder with everything already uploaded. Is that intended? I'd expect cancel to only stop the retry once the folder has finished once.

+    try {
+      this.failures.add(item, failure, () => this.props.retry(item));
+      this.syncFailedItems();


This still sends one task update per failure, each copying the whole list: 3000 failures from a full storage mean 3000 updates. Since nothing reads failedItems from the store yet, could the task keep only the failure count there and expose getFailedItems() like stop/retry for the retry modal? Otherwise, throttling the sync (~200 ms) works too.

Handled in #2327 (next PR in the stack): progress and the failed items list are sent to the task at most every 100 ms, and the list is only built when it is sent, so a folder with 3000 failing files now updates its task fewer than 100 times instead of 3000. Status changes still go out at once, after anything pending. Exposing getFailedItems() on the task would need the retry modal to change, so I'd keep that for the retry UI work.

isStopped still reads the pause from the task store. Could pause/resume come as callbacks on the task, like stop/retry, so the tracker only writes to the store?

Done in #2331: the task gets pause/resume callbacks like stop/retry, the tasks panel uses them when the task has them, and the tracker keeps its own paused state, so it no longer reads the store. Pausing or resuming an upload that already finished or was cancelled does nothing.

The trackers import tasksService, referralService and newStorageService directly. Passing them in, like uploadRepository, would let the tests check the trackers without mocking modules. Fine to leave it for the PR that wires Upload into the app.

Agreed, I'll leave it for the PR that wires Upload into the app. For now the tests go through Upload and only mock the network, so they cover the trackers through their real dependencies

Wait for upload-state cleanup before reporting completion.

If removeUploadState is slow, finish resolves whenFinished while the saved state still exists. FileUploadTracker.onStarted also starts its state write without waiting for it. A late write can therefore leave an InProcess record after cleanup. Serialize the write and deletion, and await deletion before resolving completion. The repository performs these operations asynchronously. (raw.githubusercontent.com)

Record success when an upload finishes after cancellation.

UploadManager reports an upload as succeeded when it finishes after cancel was requested. Upload then forwards that success to onItemUploaded, so the file is listed as uploaded. FileUploadTracker.finishUpload returns early when isCancelled is set. The task therefore stays Cancelled while the file remains in Drive.

The manager documents this case as success, because the item exists in the destination. The tracker should record the same result. Removing the uploaded file would contradict that contract.

Do not classify an item-removal callback error as a deletion error.

If deleteFolderByUuid succeeds but onItemRemoved throws, this catch sets folder-removal-failed. The folder is already deleted, so the task reports the wrong outcome. Handle callback errors separately from deletion errors. (raw.githubusercontent.com)

Count uploads across both phases of the concurrency test.

The first mock can still have Big uploads in progress when this line installs a second counter. The final assertion reads only the second counter. It can pass even if those existing uploads plus the retries exceed six. Keep one counter for the entire test and change only which file names fail. (raw.githubusercontent.com)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Serialize upload-state writes before reporting completion.

For a short file upload, FileUploadTracker.onStarted() can leave setUploadState() pending when this line starts removeUploadState(). If the delete completes first, the later write leaves a finished task stored as InProcess. Track the pending write, await it before removal, and await removal before resolving whenFinished(). The repository performs these operations through separate asynchronous database calls. (raw.githubusercontent.com)

Unverified finding

Wait for removal started during this yield.

If the last child ends, this await can capture undefined. Upload calls onItemUploaded after the tracker handles that success, so the callback can cancel the folder before finishUpload() resumes. Cancellation then starts removal, but whenFinished() can resolve before removal settles. Recheck and await removal started during the yield. (raw.githubusercontent.com)
