描述

Apache Airflow version

2.7.2

What happened

Problems that I discovered: 1) If DAG is on pause, then when you go into it and unpause it with the button on the left, the DAG trigger turns on, but auto-update does not turn on 2) if DAG is on pause, and you turn it on with the play button (on the right ), then the dag is launched twice - as if once due to the inclusion of the dag and the second due to the activation of an already enabled dag

What you think should happen instead

After unpause DAG button auto-update should be turned on (the same behavior like after clear task)

After push play button DAG should be triggered only one time

How to reproduce

Steps to Reproduce

  1. Have a DAG on pause.
  2. Navigate to the DAG's page in the Airflow UI.
  3. Toggle the pause off using the trigger DAG button on the left.
  4. Observe that the DAG is resumed but auto-refresh is not enabled.
  5. Now, toggle the pause off using the play button on the right.
  6. Observe that the DAG is triggered twice, seemingly once for the un-pausing and once for the activation of the already resumed DAG.

Operating System

Linux from docker, and linux (rhel)

Virtualenv installation

Deployment details

I think it's doesn't connected with deployment. I have the same problems in 2 different envs and also with airflow more earlier versions

研究方向
Investigate the UI components responsible for the DAG pause and auto refresh behavior, likely in the 'airflow/ui' directory. Check the logic in the component that handles toggle events, possibly in files like 'Dag.js' or similar. Review the comments in the issue for any hints about the root cause or proposed fixes. Also look at existing tests for pause/resume functionality to understand expected behavior.
