Walkthrough

Perses now uses PatternFly 6 token mappings for light and dark themes. PersesWrapper imports the token stylesheet and exposes the active theme through data-perses-mode around the existing provider hierarchy.

Changes

Perses PatternFly theming

Layer / File(s)	Summary
PatternFly token mappings web/src/features/perses-dashboards/assets/perses-patternfly-tokens.css	Adds light and dark aliases for colors, status states, spacing, border radii, font properties, font sizes, and line heights.
Perses theme wiring web/src/features/perses-dashboards/components/PersesWrapper.tsx	Imports the token stylesheet and wraps the existing Perses providers and dashboard content in a div with data-perses-mode set to the current theme. Provider nesting and conditional project rendering remain unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 7e1b8

The change is localized to PatternFly token mapping, and no actionable merge-blocking risk remains after normal checks and review.

Full details: Stable And Deterministic Test Names

Explanation

PASS — The pull request changes only a CSS token file and PersesWrapper.tsx. The diff adds no Ginkgo tests or test-title calls. Repository searches found no Ginkgo It, Describe, Context, or When constructs. The stable and deterministic test-name check is therefore not applicable.

Full details: Test Structure And Quality

Explanation

PASS: The pull request changes only perses-patternfly-tokens.css and PersesWrapper.tsx. The exact diff contains no Ginkgo tests, It blocks, cluster operations, waits, or assertions. Therefore the stated test-quality requirements are not applicable.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only a CSS token file and the React PersesWrapper component. The exact diff adds no Ginkgo declarations, e2e tests, OpenShift API references, unsupported namespaces, or MicroShift-incompatible assumptions. The MicroShift test compatibility check is therefore not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS — The pull request changes only a CSS token file and PersesWrapper.tsx. The diff adds no Ginkgo e2e tests, no Go test files, and no It(), Describe(), Context(), or When() declarations. Therefore, the SNO multi-node compatibility check is not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only a CSS token stylesheet and PersesWrapper.tsx. The diff adds PatternFly CSS variables, imports that stylesheet, and wraps existing UI providers in a <div data-perses-mode={theme}>. It adds no deployment manifests, operator code, controllers, replicas, affinity, topology spread constraints, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

PASS. The pull request changes only a CSS token file and a React component. The diff adds no Go code, OTE entrypoint, suite setup, logging call, or stdout write. The repository builds plugin-backend, not an openshift-tests extension binary, and the changed files contain no output APIs or process-level setup.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request changes only a CSS token file and a React component. The diff adds no Ginkgo e2e tests (It, Describe, Context, or When) and contains no IPv4 assumptions or external connectivity requirements. The check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request adds CSS design-token aliases and a data-perses-mode wrapper. The exact added lines contain no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom cryptography, or secret/token comparisons. A repository source scan found no matching weak-crypto usage.

Full details: Container-Privileges

Explanation

PASS. The pull request changes only a CSS token file and PersesWrapper.tsx. The diff contains no container or Kubernetes manifest and no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root runAs setting. The check conditions are not introduced.

Full details: No-Sensitive-Data-In-Logs

Explanation

No logging was introduced by this pull request. The new CSS file contains only static PatternFly token declarations, and the component diff adds a stylesheet import plus a data-perses-mode wrapper around existing providers. Searches found no console, logger, print, or alert calls in either changed file, and no sensitive values are emitted.
