Description

In list view, a failed folder page (e.g. while offline) made the list re-request the same page in a tight loop, stacking "Error fetching folder content" toasts. Now the failure is remembered per folder and paging pauses until the folder or sort changes, or the browser comes back online.

• Store hasFetchFailedByFolderId in the storage slice: set on fetchPaginatedFolderContentThunk.rejected, cleared on pending and resetDrivePagination
• New useFolderFetchRecovery hook: exposes canRequestMorePages so DriveExplorer stops asking for more pages after a failure
• The hook re-fetches the current folder once on the browser online event
• Trash and favorites lists are unchanged

Checklist

• Changes have been tested locally.
• Unit tests have been written or updated as necessary.
• The code adheres to the repository's coding standards.
• Relevant documentation has been added or updated.
• No new warnings or errors have been introduced.
• SonarCloud issues have been reviewed and addressed.
• QA Passed

Summary by CodeRabbit

• Bug Fixes
  • Drive folders now recover from failed content fetches when the browser reconnects, automatically retrying the request.
  • Paging pauses after a Drive folder fetch fails and resumes when the fetch can be retried, helping prevent repeated requests while offline.
  • Resetting folder pagination clears that folder’s fetch-failure state without affecting other folders.

Walkthrough

Storage now tracks fetch failures by folder. Drive folder pagination pauses after a failed fetch and retries when the browser returns online. Pending fetches and pagination resets clear the folder’s failure flag.

Merge Risk: Moderate · up to cd549

After a failed page, changing the sort can leave the file list stuck on its first page, and an older failed request can block further loading even after a newer one succeeds. Leaving and re-entering the folder recovers the list. Fix the sort-path flag reset and the stale-rejection handling before merging.

Full details: Title check

Explanation

The title names the main change: the folder list stops re-fetching in a loop after a failed page. The changeset adds per-folder fetch-failure tracking, pauses paging after a failure, and re-fetches on the browser online event, so the title matches the primary fix. The ticket prefix is acceptable.

Full details: Description check

Explanation

The description covers the problem, the approach (per-folder failure state, the new useFolderFetchRecovery hook, the online re-fetch), and the scope (trash and favorites unchanged). It also ticks the unit-test and standards items. However, the Related Issues and Related Pull Requests sections are missing, and the Testing Process and Additional Notes sections are absent. Several checklist items remain unchecked, including local testing and documentation, and the description does not say whether they are pending or not applicable.

Resolution

Add a Related Issues entry (for example, "Relates to PB-6976" or the linked issue number). Add a Testing Process section that describes how the offline and recovery behavior was verified. Add an Additional Notes section if reviewers need context, such as the cause (hasMoreItems staying true after a failed page). Resolve the unchecked checklist items, or state why each does not apply, such as documentation.

A failed older request can keep pagination blocked after a newer request for the same folder succeeds.

The rejected case sets hasFetchFailedByFolderId[action.meta.arg] to true without checking which request failed. If request A fails after newer request B has started, A sets the shared folder flag. B's fulfilled case does not clear the flag. useFolderFetchRecovery then returns canRequestMorePages: false, so the list stops loading pages even though B succeeded. The flag stays set until a later pending or resetDrivePagination runs for that folder.

Overlapping requests for one folder are possible. loadMoreItems dispatches the thunk without an in-flight check, and the stale-order guard at lines 82-85 shows that responses for superseded requests are expected.

Track the request identity of the latest fetch per folder. Set the failure flag only when the rejected action belongs to that request. Clear the flag only for the request that succeeds or starts. Apply the same rule to the fulfilled and rejected cases so that a superseded failure cannot overwrite a newer result.

Clear the failure flag when the sort changes.

After a page fails, hasFetchFailedByFolderId stays true for the current folder. resetDriveOrder resets the hasMore flags and dispatches fetchSortedFolderContentThunk, but it never clears the failure flag. The sorted thunk does not clear it either. canRequestMorePages therefore stays false after the sort, and the list stops at the first sorted page. Only a paginated fetch start or resetDrivePagination clears the flag.

Dispatch resetDrivePagination in resetDriveOrder before the sorted fetch. The reducer clears the failure flag for the current path and also resets the hasMore flags that resetDriveOrder already sets.

Suggested fix

 const resetDriveOrder = ({
   dispatch,
   orderType,
   direction,
   currentFolderId,
 }: {
   dispatch: AppDispatch;
   orderType: string;
   direction: string;
   currentFolderId: string;
 }) => {
   dispatch(storageActions.setDriveItemsSort(orderType));
   dispatch(storageActions.setDriveItemsOrder(direction));
+  dispatch(storageActions.resetDrivePagination());
   dispatch(storageActions.setHasMoreDriveFolders({ folderId: currentFolderId, status: true }));
   dispatch(storageActions.setHasMoreDriveFiles({ folderId: currentFolderId, status: true }));
   dispatch(fetchSortedFolderContentThunk(currentFolderId));
 };

Preserve reconnect events that occur before a request rejects.

While a folder request is pending, its failure flag is false, so this hook has no online listener. If the browser reconnects before that request rejects, the hook misses the reconnect event. Rejection then blocks pagination and installs a listener that waits for another reconnect.

Track reconnect events during pending requests. If a request fails after a reconnect, allow one recovery attempt without starting a retry loop. Add a regression test for this event order.
