Trigger merge status subscription when blocking MR gets merged
What does this MR do and why?
When a blocking merge request is merged, it affects the mergeability of the merge request/s it was blocking.
Since we need to update the merge widget in real-time, we need to let the subscribers know about it. To do this, we trigger the subscription whenever that happens.
How to set up and validate locally
- Enabled the
realtime_mr_status_change
feature flag so the frontend can update real-time. - Create a MR (MR A) blocked by another MR (MR B) by adding MR B as a dependency.
- Open another browser window (window B) viewing MR A.
- Watch window B.
- On window A, merge MR B. The merge widget on Window B should update in real time.
