pierrejeambrun opened a new pull request, #67564:
URL: https://github.com/apache/airflow/pull/67564
Re-introduces collective Clear on the Dag Runs list page — the
Airflow 2.x ``DagRunModelView`` action that the Airflow 3 UI did not
yet replicate. Part of #63854.
## Summary
- New ``Clear`` button in the existing ``ActionBar``, next to the
bulk ``Delete`` shipped in #67095.
- Dialog mirrors the existing single-run Clear: a segmented control
(``Clear existing tasks`` / ``Clear only failed tasks`` / ``Queue up
new tasks``), an affected-tasks preview grouped by run, and an
optional note.
- No backend change: the dialog fans out the existing
``POST /dags/{dag_id}/dagRuns/{dag_run_id}/clear`` endpoint over the
selected runs (same pattern bulk Clear on the Task Instances list
uses today). A note typed in the dialog is patched onto each run
via ``PATCH /dags/{dag_id}/dagRuns/{dag_run_id}`` after the clear
succeeds.
## Out of scope (follow-up PRs)
- Bulk **Mark as success / failed** on the Dag Runs list — the other
half of #63854.
- Per-run partial-success handling (today the first failure stops the
batch, same as bulk Clear on the Task Instances list).
## Screenshots
- _Action bar with new ``Clear`` button (single Dag and multiple Dags)_
- _Clear dialog — default segmented option (``Clear existing tasks``) with
affected-tasks preview grouped by run_
- _Clear dialog — ``Clear only failed tasks`` option_
- _Clear dialog — ``Queue up new tasks`` option_
