🐛 Fix OOM: single worker for coverage suite by clubanderson · Pull Request #4177 · kubestellar/console

clubanderson · 2026-04-01T15:16:05Z

7800+ tests with coverage OOMs at 8GB. Use --maxWorkers=1 to process one file at a time. Slower (~25 min) but completes reliably.

Pull request overview

This PR aims to make the hourly Vitest coverage workflow complete reliably on GitHub-hosted runners by reducing memory pressure, and it also includes several user-facing copy updates to reference “KubeStellar Console”.

Changes:

Adjust the hourly coverage workflow to run Vitest coverage with a single worker and a lower V8 old-space limit.
Update multiple UI strings to say “KubeStellar Console” instead of “KubeStellar”.

web/src/components/rewards/LinkedInShare.tsx

                Did you share on LinkedIn?
              </h3>
              <p className="text-sm text-muted-foreground mb-4">

+                Confirm that you shared KubeStellar Console to earn your coins!
              </p>


The share dialog posts https://kubestellar.io (see KUBESTELLAR_URL), but this confirmation copy now tells users they shared “KubeStellar Console”. This is misleading if the shared link is the main KubeStellar site. Either change the shared URL to the Console-specific URL (e.g., hosted console or repo/docs) or revert the copy to match what’s actually being shared.

    coins: 200,
    label: 'LinkedIn Share',
-    description: 'Share KubeStellar on LinkedIn',
+    description: 'Share KubeStellar Console on LinkedIn',


This reward description says “Share KubeStellar Console on LinkedIn”, but the current LinkedIn share implementation shares https://kubestellar.io (not a Console-specific URL). Please align the description with the actual shared target, or update the share implementation to share the Console URL.

Suggested change

description: 'Share KubeStellar Console on LinkedIn',

 const COMPARISON_DATA: ComparisonRow[] = [
  { feature: 'Open Source', headlamp: 'Yes', console: 'Yes', headlampNote: 'Apache 2.0', consoleNote: 'Apache 2.0' },
-  { feature: 'CNCF Status', headlamp: 'Sandbox', console: 'KubeStellar is Sandbox' },
+  { feature: 'CNCF Status', headlamp: 'Sandbox', console: 'KubeStellar Console is Sandbox' },


The console value for the “CNCF Status” row is a sentence (“KubeStellar Console is Sandbox”) while the rest of the table uses short values (e.g., “Yes”, “Sandbox”). For readability and consistency, consider using console: 'Sandbox' and moving any extra context into consoleNote (or similar).

Suggested change

{ feature: 'CNCF Status', headlamp: 'Sandbox', console: 'KubeStellar Console is Sandbox' },

{ feature: 'CNCF Status', headlamp: 'Sandbox', console: 'Sandbox', consoleNote: 'KubeStellar Console is Sandbox' },

With --maxWorkers=1 the comment notes ~25 minutes runtime; the job timeout is currently 30 minutes. That leaves little headroom for runner variance and may cause intermittent timeouts. Consider increasing timeout-minutes accordingly when forcing single-worker execution.

PR title/description focus on the coverage-suite OOM fix, but this PR also changes multiple user-facing strings (“KubeStellar” → “KubeStellar Console”) across the app. Please update the PR description to reflect the additional scope or split the copy/branding changes into a separate PR to keep reviews and rollbacks isolated.
