The Bump widgets (header, footer, head-bump, chat-panel-bump) get the latest Self-Managed version from compile-partial.js, which fetched antora.yml from redpanda-data/docs. That repo is private, so the fetch has returned 404 since it went private. Every release since then has shipped the widgets without a version: the API pages on docs.redpanda.com use Self-Managed v as the search tag and an empty latest-redpanda-version meta tag. You can see both on https://docs.redpanda.com/api/doc/admin/ and in v4.2.2's widgets.

  • The version now comes from the live docs site's <meta name="latest-redpanda-version"> on https://docs.redpanda.com/home/, which needs no token. LATEST_ENTERPRISE still overrides it.
  • Without a version a CI build now fails, so a release cannot ship the widgets empty again. A local build only warns, so it still works offline.
  • The fetch drains error responses, uses no keep-alive agent, and times out after 10 s. On Node 22 the unread 404 body kept the process open, so gulp bundle hung at compileWidgets. CI runs Node 18, so CI only warned.

Tested:

  • gulp bundle with no LATEST_ENTERPRISE: rc 0 in 17 s. head-bump has content="26.2", and the footer search tag is Self-Managed v26.2 (with the Algolia env set).
  • With the URL pointed at a 404: CI=true exits 1 with the error, and without CI it warns and exits 0.
  • The old script hangs on the same compile after 20 s.

Walkthrough

fetchLatestVersion now reads the latest-redpanda-version meta tag from the public docs homepage and accepts only versions in digits.digits format. It rejects non-200 responses, missing or invalid tags, request errors, and requests that exceed 10 seconds. If lookup fails, ensureRootVersion exits with an error in CI and warns locally. LATEST_ENTERPRISE can still supply the version directly.

Priority: Normal

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

Suggested reviewers: feediver1

Merge Risk: Moderate · previous review 38569

Version lookup can still interrupt or stall widget builds, and a local build with CI=false can fail instead of warning. Address these paths before merging.

Review comments at @compile-partial.js:
- Line 140: Update the CI check in the lookup failure path to compare
process.env.CI explicitly with the string 'true', so values such as 'false' do
not trigger the build failure.
- Line 38: Attach an error listener to res in the response-handling flow and
reject the lookup when the response emits an error, preserving the existing
request error handling and warning behavior.
- Line 49: Replace the socket-inactivity timeout on req with an absolute
deadline that destroys the request if the complete lookup exceeds 10 seconds,
including during connection setup or intermittent responses. Clear the deadline
when the lookup settles.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Set a deadline for the complete lookup.

req.setTimeout(10000) measures socket inactivity after connection. It does not bound connection setup or a response that sends data at intervals shorter than 10 seconds. In either case, widget compilation can still hang instead of reaching the CI error or local warning. Use an absolute timer that destroys req, and clear it when the lookup settles. (nodejs.org)

Not changing this: the socket timeout already covers a stalled connection, and a slow trickle from docs.redpanda.com is unlikely enough that an extra overall timer is not worth it here.

@JakeSCahill Understood. You accept the residual risk of having no overall deadline for this lookup. I won’t press for an additional timer.
