samraj2k opened a new pull request, #73717:
URL: https://github.com/apache/airflow/pull/73717
## Summary
- Add a normalized `bundle_name` tag to `dag_processing.processor_timeouts`
so timeouts for the same relative `file_path` in different Dag bundles are
separate metric series.
- Update the metric registry description and regression tests for bundle
attribution, name normalization, and multi-team tagging.
## Local verification
- `breeze run --skip-image-upgrade-check pytest
airflow-core/tests/unit/dag_processing/test_manager.py -xq`: **177 passed, 5
skipped, 1 warning**. The skipped tests require PostgreSQL; this run used
SQLite.
- `prek run --from-ref upstream/main --stage pre-commit`: passed, including
Ruff, mypy, and the metrics registry check.
- `prek run --from-ref upstream/main --stage manual --skip
compile-ui-assets-dev --skip view-skill-eval --skip run-skill-eval-codex`:
passed.
- A controlled runtime probe exercised Airflow's processor timeout path
through the configured StatsD backend and a local UDP receiver. For the same
`file_path`, it captured:
```text
airflow.dag_processing.processor_timeouts,file_path=shared.py,bundle_name=bundle_alpha:1|c
airflow.dag_processing.processor_timeouts,file_path=shared.py,bundle_name=bundle_beta:1|c
```
The Breeze tests used an existing CI image with the branch's sources
mounted. A fresh local image build was blocked by a Python.org certificate
trust error in the build container.
