Conversation
…er_statuses Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
WalkthroughThe changes remove a duplicate image-status helper, clarify exception and null checks in the OOM restart playbook, and remove an unused ChangesImage status utility cleanup
OOM restart handling cleanup
API import cleanup
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The job-restart path can still fail when no pod exists and can hide API or programming errors instead of surfacing them, so the PR is not merge-ready until missing pods are handled explicitly and exception handling is narrowed. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
✨ Finishing Touches🧪 Generate unit tests (beta)

Handle a missing pod and narrow the exception handling.
get_job_latest_pod returns None when no pod exists, so pod.status raises AttributeError outside this handler. except Exception also converts API, authentication, response-parsing, and programming errors into a logged return. Handle pod is None explicitly, catch only a documented expected exception, and propagate unexpected failures with their traceback.

Summary
Main fix —
playbooks/robusta_playbooks/image_pull_backoff_enricher.py: the file importsget_image_pull_backoff_container_statusesfromrobusta.core.playbooks.pod_utils.imagepull_utilsand then immediately shadows it with a local copy (ruff F811). The two are not equivalent:waiting.reason in ["ImagePullBackOff", "ErrImagePull"]waiting.reason == "ImagePullBackOff"Because the local def wins, the reporter silently ignores pods in
ErrImagePull— whileget_image_pull_backoff_enrichment(called right after) uses the shared, broader logic. Removing the stale copy restores the imported implementation and makes reporter + enricher consistent. Also removed the imports (enum,Flag,List,ContainerStatus,PodStatus) that are unused once the duplicate is gone.Also included:
src/robusta/api/__init__.py—ResourceAttributeswas listed twice in the same import block (F811); removed the duplicate.playbooks/robusta_playbooks/job_restart_on_oomkilled_community.py— bareexcept:→except Exception:andstatus.state.running == None→is None(E722/E711).Testing
