[v3-3-test] Add API endpoint for backfill dag run entries - #70127
Merged
Conversation
* Add GET /backfills/{backfill_id}/dag_runs endpoint
Adds a new public API endpoint that returns the BackfillDagRun entries
for a given backfill with joined DagRun state. Users can see what
happened in a backfill: which dates ran, their states (queued, running,
success, failed), and which slots were skipped (with reason).
- BackfillDagRunResponse / BackfillDagRunCollectionResponse models
- LEFT OUTER JOIN via joinedload includes skipped slots (null dag_run_id)
- Pagination via limit/offset, default ordering by sort_ordinal
- 404 when backfill doesn't exist
- 8 unit tests covering happy path, skipped slots, 404, pagination,
empty backfill, and ordering contract
closes: apache#46250
* Align backfill dag run response identifiers
(cherry picked from commit 6f88f29)

The #70127/#69719 reverts (now on v3-3-test) removed BackfillDagRunResponse, BackfillDagRunCollectionResponse and bundle_version from the API spec. Regenerated generated.py from the current spec with datamodel-code-generator>=0.71.0 so it reflects the reverts in the new-tool format. mypy airflow-ctl clean; no tests reference the removed models.

…toolchain (#70670) (#70976) * Raise the datamodel-code-generator floor for the codegen toolchain (#70670) (cherry picked from commit b301429) Manual backport: datamodel-code-generator floor bumped 0.33.0 -> >=0.71.0 and models REGENERATED against v3-3-test's own spec (not copied from main). Test constructions in test_operations.py updated for the now-required nullable fields. test_task_command.py is main-only; main's divergent test_operations.py tail (ctl task-instance ops not on this branch) intentionally not backported. * Fix ConnectionResponse construction to use schema alias in airflow-ctl test The regenerated model exposes the field as `schema_` with `Field(alias="schema")` and no `populate_by_name`, so pydantic requires the alias `schema=` at construction. Matches main's fix (#70670): construct with `schema=` plus `# type: ignore[call-arg]`. * Serialize connection mock responses by alias in airflow-ctl tests ConnectionResponse.schema_ has Field(alias=schema) and no populate_by_name, so the source validates responses by the schema alias. The mock handlers dumped the model by field name, breaking the round-trip. Dump connection_response / connections_response mocks with by_alias=True (matches main #70670). * Regenerate airflow-ctl datamodels after merging v3-3-test The #70127/#69719 reverts (now on v3-3-test) removed BackfillDagRunResponse, BackfillDagRunCollectionResponse and bundle_version from the API spec.

Backport of #67381 to
v3-3-test.Cherry-picked from 6f88f29.
One conflict, in the generated
ui/openapi-gen/requests/services.gen.tsimport type { ... }line:mainhad added the newListBackfillDagRuns*imports alongside other symbols (GetDagRunStateCountsUi*,GetCalendarDeadlines*) that do not exist onv3-3-test. Resolved by keeping thev3-3-testimport list and adding onlyListBackfillDagRunsData/ListBackfillDagRunsResponse(the endpoint's own types, whichtypes.gen.tsexports here), dropping the unrelated main-only symbols. All other generated files auto-merged.Was generative AI tooling used to co-author this PR?
