CVAT Digest, August 2025: One-Step Account Cleanup, Smarter Labels, and More

TL;DR

• One-step user off-boarding: remove a user with all their data via a new Django CLI command.
  
  
• Smarter label schema checks: the Raw Labels Editor now blocks invalid configs before they hit the server.
  
  
• Smoother reviews: Issue dialogs auto-reposition to stay fully visible near frame edges.
  
  
• Cleaner APIs: deleted_frames in job meta now only reports frames from the current job segment.
  
  
• Lower backend load: preview requests for Projects/Tasks/Jobs are sent sequentially to avoid spikes.

‍

Added

Delete a user together with all their resources (admin CLI)

• Context: Adds a safe server-side flow to remove a user and all associated data in one go.
  Impact: Admins can fully deprovision accounts without manual cleanup. Built-in validation prevents unsafe deletions (e.g., community users still in orgs with other members; SaaS users with active subscriptions).
• Example: python manage.py deleteuser <user_id>

‍

Changed

Raw Labels Editor: stronger validation

• Context: UI now catches malformed/unsupported label configurations earlier.
• Impact: Fewer bad payloads reaching the backend; clearer inline feedback for editors. No action needed unless your current config is invalid.

Preview requests sent sequentially to reduce server load

• Context: Fetching previews for Projects/Tasks/Jobs could spike concurrency.
• Impact: More stable performance under load; slightly lower peak concurrency for preview calls.

‍

Fixed

Issue dialog never opens off-screen

• Context: In review mode, dialogs near frame corners could render outside the viewport.
• Impact: Dialogs now auto-reposition and remain fully visible. No more zooming out to find them.

deleted_frames in job meta constrained to the job segment

• Context: API could return deleted_frames outside the job’s segment in /jobs/{id}/data/meta.
• Impact: Client code relying on this field now receives only relevant frames. If you worked around the previous behavior, you can simplify your client logic.‍
• Notes: Includes a test for video tasks with frame step > 1.
