PR Summary

Align PercentageValidator bounds to match the cluster-autoscaler-operator webhook and OCP documentation — value must be strictly between 0 and 1.

Detailed Description of the Issue

The ROSA CLI accepted --scale-down-utilization-threshold 0, storing "0.000000" in OCM. The cluster-autoscaler-operator's validating admission webhook rejects this value, causing Hive to enter a permanent patch rejection loop and blocking cluster upgrades.

The OCP 4.18 documentation states the value "must be a value greater than 0 but less than 1." Additionally, setting the threshold to 0 silently disables scale-down in the upstream Kubernetes autoscaler (kubernetes/autoscaler#2221).

Related Issues and PRs

  • Jira: ROSAENG-62105
  • Related: cluster-autoscaler-operator webhook validation, OCP documentation

Type of Change

  • fix - resolves an incorrect behavior or bug.

Previous Behavior

  • CLI accepted --scale-down-utilization-threshold 0 and --scale-down-utilization-threshold 1 as valid inputs
  • These boundary values were stored in OCM and applied to the cluster
  • The cluster-autoscaler-operator's validating webhook rejected value 0, causing Hive to enter a permanent patch rejection loop
  • Value 0 silently disabled scale-down in the autoscaler without user awareness
  • Value 1 is outside the documented valid range per OCP docs
  • NaN was accepted as valid input and passed to OCM
  • Error messages did not include the actual invalid value, making debugging harder

Behavior After This Change

  • CLI now rejects --scale-down-utilization-threshold 0 and --scale-down-utilization-threshold 1 during validation
  • CLI now rejects NaN values
  • Only values strictly between 0 and 1 (exclusive bounds) are accepted
  • Error messages now include the actual invalid value (e.g., "expecting a floating-point number greater than 0 and less than 1, got 0")
  • CLI validation matches cluster-autoscaler-operator webhook and OCP documentation
  • Help text updated to clarify "greater than 0 and less than 1" (not "between 0 and 1")

How to Test (Step-by-Step)

Preconditions

  • ROSA CLI built from this branch
  • OCM credentials configured
  • Access to a ROSA cluster (or use --dry-run mode)

Test Steps

Test 1: Verify boundary values are rejected

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold 0
# Expected: error validating utilization-threshold: expecting a floating-point number greater than 0 and less than 1, got 0

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold 1
# Expected: error validating utilization-threshold: expecting a floating-point number greater than 0 and less than 1, got 1

Test 2: Verify NaN is rejected

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold NaN
# Expected: error validating utilization-threshold: expecting a floating-point number greater than 0 and less than 1, got NaN

Test 3: Verify valid values are accepted

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold 0.5
# Expected: autoscaler created successfully (or validation passes)

rosa edit autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold 0.7
# Expected: autoscaler updated successfully (or validation passes)

Test 4: Verify other boundary cases

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold -1
# Expected: error validating utilization-threshold: expecting a floating-point number greater than 0 and less than 1, got -1

rosa create autoscaler --cluster=<cluster-name> --scale-down-utilization-threshold 2
# Expected: error validating utilization-threshold: expecting a floating-point number greater than 0 and less than 1, got 2

Expected Results

  • Boundary values (0, 1) are rejected with clear error messages
  • NaN is rejected
  • Valid values (0 < value < 1) are accepted
  • Error messages include the actual invalid value for easier debugging

Proof of the Fix

Unit Tests:

  • pkg/ocm/validators_test.go - Added tests for boundary values 0, 1, and NaN
  • All unit tests pass with make test

E2E Tests:

  • tests/e2e/rosa_autoscaler_test.go - Updated validation expectations
  • tests/e2e/test_rosacli_cluster.go - Updated error message expectations with actual values
  • All autoscaler e2e tests updated to use valid threshold value (0.5)

Validation:

  • make lint - passes
  • make test - passes
  • make rosa - builds successfully

Breaking Changes

  • No breaking changes

This is a bug fix that makes the CLI validation stricter to match the cluster-autoscaler-operator webhook and OCP documentation. While this technically rejects previously-accepted values (0 and 1), these values:

  • Were already rejected by the cluster-autoscaler-operator webhook, causing cluster issues
  • Are documented as invalid in OCP documentation
  • Led to undefined/broken behavior when used

Users who were using these invalid values would have already encountered cluster-side validation failures. This change moves the validation earlier (to the CLI) to provide clearer error messages and prevent cluster-side issues.

Developer Verification Checklist

  • Commit subject/title follows [JIRA-TICKET] | [TYPE]: <MESSAGE>.
  • PR description clearly explains both what changed and why.
  • Relevant Jira/GitHub issues and related PRs are linked.
  • make install-hooks has been run in this clone.
  • Tests were added/updated where appropriate.
  • I manually tested the change.
  • make test passes.
  • make lint passes.
  • make rosa passes.
  • Documentation or repo-local agent guidance was added/updated where appropriate.
  • Any risk, limitation, or follow-up work is documented.

Summary by CodeRabbit

  • Bug Fixes

    • Percentage validation now accepts only values strictly between 0 and 1.
    • Boundary values (0 and 1), NaN, and other invalid inputs are rejected with clearer, more specific errors.
    • Autoscaler validation now reports offending threshold values and provides improved feedback for invalid ranges and numeric inputs.
  • Documentation / Help Text

    • Autoscaler flag help text and validation messages now use clearer, more consistent wording.
  • Tests

    • Expanded coverage for percentage boundaries, NaN, autoscaler thresholds, and updated CLI validation messages.

Full details: Test Structure And Quality

Explanation

The PR adds three Ginkgo It blocks in pkg/ocm/validators_test.go with assertions that have no failure messages: PercentageValidator("0") at line 93, PercentageValidator("1") at line 97, and PercentageValidator("NaN") at line 101. These assertions directly violate the requirement for meaningful assertion messages. The added tests each cover one behavior, and the changed E2E scenarios use existing setup/cleanup and add no new Eventually or Consistently calls.

Resolution

Add a diagnostic message to each new assertion, for example: Expect(PercentageValidator("0"), "percentage validator must reject the boundary value 0").ToNot(BeNil()), with equivalent messages for 1 and NaN. Add the input or flag values to the shared E2E loop assertions if the new boundary cases fail without identifying which case failed.

The validator unit tests now cover 0, 1, and NaN, but the higher-level CLI tests still only exercise -1, 2, and 1.3. Since this bug escaped through the real flag path in pkg/clusterautoscaler/flags.go, please add at least one command/e2e case that proves the CLI rejects 0 or 1 end-to-end.

While looking at adding the boundary cases, I noticed that the utilization-threshold entries for "-1" and "2" in the validation maps produce identical fmt.Sprintf output (same error string). In Go map literals, wouldn't duplicate keys mean only the last entry survives? If so, only "2" would actually be tested and "-1" would be silently dropped — is that intentional, or is there something else I'm missing about how these maps are consumed?

If it is a duplicate key issue, swapping the existing values to "0" and "1" would cover the new boundary behavior — though it's worth noting that only one of the two would actually be exercised. A follow-up PR could restructure the maps (e.g., invert so the input is the key) to ensure all cases run.

The latest push adds 0 and 1 boundary e2e cases for the create-classic and edit-classic sections ✅. However, the edit-HCP section still has the duplicate-key problem (only '2' executes, '-1' is dropped) and doesn't include the 0/1 boundary cases. That section should be aligned with the other two before resolving this thread.

These look like real e2e hardening issues, but they’re outside the changed hunk and not introduced by this utilization-threshold fix. I wouldn’t block this PR on them; they’re better handled in a focused follow-up against tests/e2e/test_rosacli_cluster.go.

Updates to Address Review Feedback

I've addressed the outstanding review feedback from @olucasfreitas about adding end-to-end CLI test coverage for the boundary cases (0 and 1).

What Changed

Issue Discovered:
While working on adding the boundary tests, I noticed the existing e2e validation tests had what appears to be a bug/limitation: multiple invalid threshold values (-1, 0, 1, 2) produced identical error messages, which created duplicate keys in the test maps. In Go, when map literals have duplicate keys, only the last entry is retained—meaning some test cases may not have been executing as intended.

Solution:
Rather than working around this or deferring to a follow-up, I've updated the approach:

  1. Enhanced the error message to include the actual invalid value:

    • Before: "expecting a floating-point number greater than 0 and less than 1"
    • After: "expecting a floating-point number greater than 0 and less than 1, got 0"
  2. Added comprehensive boundary tests - now testing all invalid values:

    • -1 (below lower bound)
    • 0 (at lower bound - must be > 0, not >= 0)
    • 1 (at upper bound - must be < 1, not <= 1)
    • 2 (above upper bound)
  3. Benefits:

    • ✅ More informative error messages for users (shows which value was rejected)
    • ✅ Complete e2e test coverage for all boundary cases
    • ✅ All test cases now execute as they appear in the code
    • ✅ Addresses the original review request without additional complexity

Commit

Latest commit: 96fc9e4 - "test: include actual value in PercentageValidator error and add comprehensive boundary tests"

Ready for re-review. Let me know if you'd like this PR reopened or if I should open a fresh one.

@nephomaniac: This pull request references ROSAENG-62105 which is a valid jira issue.

Warning: The referenced jira issue has an invalid target version for the target branch this PR targets: expected the bug to target the "5.1.0" version, but no target version was set.

Details

In response to this:

Summary

  • Align PercentageValidator bounds to match the cluster-autoscaler-operator webhook and OCP documentation
  • Change number < 0 to number <= 0 and number > 1 to number >= 1 — value must be strictly between 0 and 1
  • Add test cases for 0 and 1 being rejected

Context

The ROSA CLI accepted --scale-down-utilization-threshold 0, storing "0.000000" in OCM. The cluster-autoscaler-operator's validating admission webhook rejects this value, causing Hive to enter a permanent patch rejection loop and blocking cluster upgrades.

The OCP 4.18 documentation states the value "must be a value greater than 0 but less than 1." Additionally, setting the threshold to 0 silently disables scale-down in the upstream Kubernetes autoscaler (kubernetes/autoscaler#2221).

Jira: https://redhat.atlassian.net/browse/ROSAENG-62105

Summary by CodeRabbit

  • Bug Fixes
  • Percentage validation now requires values strictly greater than 0 and strictly less than 1.
  • Boundary inputs (0 and 1) and NaN are rejected, with invalid values included in relevant error messages.
  • Documentation / Help Text
  • Autoscaler flag help text and validation errors now use clearer, more consistent wording.
  • Tests
  • Updated unit and end-to-end tests to cover threshold boundaries and revised validation messages.

/retest-required

Fixed lint failure - added required depguard nolint annotations for architectural boundary violations in pkg/clusterautoscaler/flags.go (per ROSAENG-62490 linting rules that were added after the original PR).

Updates - Fixed CodeRabbit Finding

Fixed: Missing space in log-verbosity error message concatenation (was equalto, now equal to)

E2E Test Failures: The two failing e2e tests (e2e-presubmits-pr-rosa-hcp-advanced and e2e-presubmits-pr-rosa-sts-advanced) are infrastructure failures unrelated to our code changes:

error: unable to check whether to include image ... tag "rhel-coreos" has an invalid 
io.openshift.build.versions or io.openshift.build.version-display-names label

This is a CI payload creation issue. The tests failed during cluster setup before our code was even executed. These are safe to /retest or ignore as they're not caused by the PR changes.

Please complete the PR template sections — particularly 'Previous Behavior', 'Behavior After This Change', and the developer verification checklist. The summary and context are great but the template is required per CONTRIBUTING.md.

ROSAENG-62105 needs a target version (5.1.0 per the Prow warning) to clear the Jira lifecycle check.

The author has pushed 3 new commits addressing all prior review feedback (NaN guard, e2e coverage, help text alignment, depguard annotations, CodeRabbit space fix). The PR looks close to ready — there are a few remaining e2e test mismatches to fix (see inline comments) but the core logic is solid. /reopen

The trailing period was removed from the validator source but kept in these e2e expectations. The cores-range and memory-range assertions will fail at ContainSubstring because the CLI no longer emits the period. Remove the period to match the GPU range entries that were already corrected.

This section still has the duplicate-key problem that was fixed in the create-classic and edit-classic sections. Both '-1' and '2' entries resolve to the same map key, so only '2' runs. Also missing the 0/1 boundary cases. Please align with the other two sections by including 'got X' in each entry.

… and 1

Align PercentageValidator bounds with the cluster-autoscaler-operator
webhook and OCP documentation. Reject 0, 1, and NaN as invalid values.
Fix error strings to comply with Go staticcheck ST1005 conventions.
Update flag help text and all affected test expectations.
…or and add comprehensive boundary tests

- Update PercentageValidator error message to include the actual invalid value
- This makes errors more user-friendly and allows testing all boundary cases
- Add e2e tests for all invalid threshold values: -1, 0, 1, and 2
- Previously, duplicate error messages prevented testing multiple invalid values
- Addresses reviewer feedback from PR openshift#3398

…ral boundary violations

- Add nolint:depguard annotations to pkg/clusterautoscaler/flags.go
- Required after touching file per ROSAENG-62490 architectural linting rules
- File imports cobra/pflag/interactive which violate core layer boundaries
- Annotations allow lint to pass until file can be properly refactored
- Remove trailing periods from cores-range and memory-range error messages
- Add boundary test cases (0, 1) to edit-HCP validation tests
- Fix duplicate map keys in edit-HCP by including actual values in error messages
- Align edit-HCP validation tests with create-classic and edit-classic formats

Addresses feedback from @olucasfreitas:
- Line 679, 694 (create-classic): Remove trailing period
- Line 846, 861 (edit-classic): Remove trailing period
- Line 1021, 1036 (edit-HCP): Remove trailing period
- Line 1048-1063 (edit-HCP): Add 'got X' to make unique map keys and add 0/1 boundary cases
