Fixes #58928 The "Triggered DAG" button from `TriggerDagRunOperator` now appears in real-time without requiring a manual page refresh. ### Problem Previously, extra links (including the "Triggered DAG" button) only appeared after: 1. The parent task completed 2. User manually refreshed the browser page This reduced the utility of extra links, especially for monitoring triggered child DAGs in real-time. ### Solution - Add smart polling to `ExtraLinks` component using the existing `useAutoRefresh` hook - Poll automatically when DAG is active and links are not yet available - Stop polling once extra links appear to reduce server load - Respects global `auto_refresh_interval` config and DAG paused state ### Changes Made - Modified `airflow-core/src/airflow/ui/src/pages/TaskInstance/ExtraLinks.tsx` - Added `refetchInterval` logic with conditional polling - Follows the same pattern used in `Details.tsx` for polling task instances - No breaking changes, no new dependencies ### Testing #### Code Quality: - [x] TypeScript types are correct - [x] Build succeeds without errors (`vite build` passes) - [x] Follows existing patterns (`useAutoRefresh` hook) - [x] No new dependencies added - [x] Clear inline comments explain the logic #### Manual Testing Checklist (for reviewers): - [ ] Start Breeze with `breeze start-airflow --dev-mode` - [ ] Create DAG with `TriggerDagRunOperator` - [ ] Trigger the parent DAG - [ ] Verify "Triggered DAG" button appears immediately (no refresh needed) - [ ] Verify button remains visible while child DAG runs - [ ] Verify polling stops once button appears (check Network tab in DevTools) - [ ] Verify respects DAG paused state ### Performance Impact ✅ **Positive**: Polling stops when links appear, actually reducing server load compared to continuous polling ✅ Respects `auto_refresh_interval` config (user-configurable) ✅ Only polls when DAG is active (not paused) ### Related This fix uses the same auto-refresh pattern already established in `Details.tsx` for task instance polling, ensuring consistency and maintainability across the codebase. --- **Type**: Bug Fix **Component**: UI (React) **Breaking Changes**: None **New Dependencies**: None -- This is an automated message from the Apache Git Service.
