Intermittent Duplicate Folder Creation During Drag-and-Drop Upload in FileCloud

Original Question or Issue:

  • Duplicate folders are created intermittently when dragging and dropping folders into FileCloud.
  • Issue occurs primarily when uploading folders containing multiple subfolders.

Environment:

  • Product - FileCloud Server
  • Version - 

    23.261.2.33071

  • Platform - Any

Steps to Reproduce:

  • Drag and drop a folder containing multiple subfolders into FileCloud.
  • Observe intermittent duplicate folder creation.

Error or Log Message:

  • Multiple concurrent core/createfolder requests for the same parent folder.
  • Some requests return HTTP 200, while others return HTTP 400.

Defect or Enhancement Number:

FCL-13498


Cause:

  • The UI sends folder-creation requests for dropped folders and subfolders without waiting for previous requests to complete.
  • Subfolder requests also create missing parent folders.
  • Concurrent requests can create multiple copies of the same parent folder.
  • Duplicate count corresponds to the number of concurrent folder-creation requests that successfully complete.

Resolution or Workaround:

  • Proposed UI fix: process folder-creation requests sequentially and wait for completion before uploading folder contents.
  • Backend improvement also identified to prevent duplicate intermediate folder creation during concurrent requests.
  • Fix ETA not yet scheduled.
  • Monitor FileCloud Server Release Notes.
