What does this PR do?

This PR removes the formatting %w when the error is nil.

Motivation

Displaying an nil error when using %w result in a not so great message %!w(<nil>)

Describe how to test/QA your changes

Done by running unit tests.

Possible Drawbacks / Trade-offs

💭 thought: ‏ Shouldn't that be

Suggested change
if addDDAgentUser(ctx) != nil {
if err = addDDAgentUser(ctx); err != nil {
return fmt.Errorf("error creating dd-agent user: %w", err)
}

instead?

Keeping track of the error would be good. (sorry for previous comments, I misread)

Baseline: 152a0e7
Comparison: e7bd0ea

Performance changes are noted in the perf column of each table:

  • ✅ = significantly better comparison variant performance
  • ❌ = significantly worse comparison variant performance
  • ➖ = no significant change in performance

No significant changes in experiment optimization goals

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

There were no significant changes in experiment optimization goals at this confidence level and effect size tolerance.

Explanation

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

  1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

  2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

  3. Its configuration does not mark it "erratic".
