  • Unset podInfo InitialAttemptTimestamp to exclude the preEnqueue failure time from the pod_scheduling_duration_seconds metric.
  • Use a pointer to an InitialAttemptTimestamp.
  • Add a new case for the TestPerPodSchedulingMetrics unit test

Fixes #117979

Special notes for your reviewer:

Does this PR introduce a user-facing change?

the `pod_scheduling_duration_seconds` metrics won't consider the time when a Pod fails PreEnqueue (like being gated).

@helayoty the latest logic looks good, it's just some UTs may have assumed Timestamp/InitialAttemptTimestamp in another way, so may need to adapt those UTs.

@Huang-Wei , This UT doesn’t make sense with the change as it tests that the InitialAttemptTimestamp is not changed with a different number of attempts while it will change now. Should we remove it? Or reverse the logic to make sure it fails if it didn't change?

I'm wondering if it's possible to leverage help a fakeClock? Like, initialize the podInfo with a fakeClock to ensure the time is the same when it's created and firstly time added to activeQ, and then step() when it needs to do another attempt or movement.

LGTM. Would you mind squashing the commits?

And could you fill the release note section? as it changes how pod_scheduling_duration_seconds is calculated.

Per discussion in https://github.com/kubernetes/enhancements/pull/4065/files#r1231487092, we reached a concensus to change the semantics of pod_scheduling_duration_seconds to exclude PreEnqueue by default, and then cherrypick the changes along with a few follow-ups.

We should be using a test table for these cases or split into separate test functions. That should make tests easier to debug in the future.

This is beyond the scope of this PR, but please consider working on this after this has been merged and cherry-picked.

Although, I would prefer this new test goes into a separate function in this PR.

we do have some test code not following the table-driven test style. it can be followed-up with other tests.

I agree to follow the table-driven test style. I didn't want to have an out-of-scope change in this PR. I will follow up with another PR to address this comment.
