Describe the Bug

The newtUpdateAvailable field in the Sites API response (GET /org/{orgId}/sites) incorrectly shows false for sites running outdated Newt versions. Two root causes were identified:

Bug 1 (primary): Tag sorting + duplicate tags

The code in server/routers/site/listSites.ts fetches /repos/fosrl/newt/tags and takes tags[0].name as the latest version. However, the Newt repo has duplicate tags with and without v prefix for versions 1.8.0–1.10.3. The GitHub Tags API returns v-prefixed tags before unprefixed ones:

# Actual order from GET /repos/fosrl/newt/tags:
v1.10.3    ← tags[0] — taken as "latest"!
v1.10.2
v1.10.1
...
1.11.0     ← the ACTUAL latest version (never reached)
1.10.4
1.10.3     ← same version as v1.10.3

Result: latestNewtVersion = "v1.10.3" instead of "1.11.0"

  • semver.lt("1.10.1", "v1.10.3") → true (correct for 1.10.1 sites)
  • semver.lt("1.10.3", "v1.10.3") → false (wrong — 1.11.0 is available)

Bug 2 (secondary): Cache invalidation without fallback

The cached version has a 1-hour TTL. After expiry, if the GitHub fetch times out (1.5s limit), the cache returns null and ALL sites default to newtUpdateAvailable: false. A stale-while-revalidate pattern would preserve the last known value until a successful fetch.

Suggested fixes:

  1. Sort fetched tags by semver.rcompare() and deduplicate before selecting tags[0]
  2. Use /repos/fosrl/newt/releases/latest instead of /tags (returns the actual latest release, not affected by tag ordering)
  3. Persist cached version until next successful fetch (stale-while-revalidate)
  4. Clean up duplicate v-prefixed tags in the Newt repo

Environment

  • OS Type & Version: Ubuntu 24.04 (Hetzner Cloud)
  • Pangolin Version: 1.17.0 (Enterprise Edition)
  • Gerbil Version: 1.17.0
  • Traefik Version: 3.6.13
  • Newt Version: Mix of 1.10.1, 1.10.3, 1.11.0 across 10 sites
  • Olm Version: n/a

To Reproduce

  1. Have sites running Newt 1.10.3 and 1.11.0
  2. Call GET /org/{orgId}/sites
  3. Observe that sites on 1.10.3 show newtUpdateAvailable: false
  4. Verify with curl https://api.github.com/repos/fosrl/newt/tags | jq '.[0].name' — returns v1.10.3 not 1.11.0

Expected Behavior

All sites running Newt < 1.11.0 should show newtUpdateAvailable: true, since 1.11.0 is the latest release.

Two root causes were identified: **Bug 1 (primary): Tag sorting + duplicate tags** The code in `server/routers/site/listSites.ts` fetches `/repos/fosrl/newt/tags` and takes `tags[0].name` as the latest version. However, the Newt repo has **duplicate tags** with and without `v` prefix for versions 1.8.0–1.10.3. The GitHub Tags API returns `v`-prefixed tags before unprefixed ones: ``` # Actual order from GET /repos/fosrl/newt/tags: v1.10.3 ← tags[0] — taken as "latest"! v1.10.2 v1.10.1 ... 1.11.0 ← the ACTUAL latest version (never reached) 1.10.4 1.10.3 ← same version as v1.10.3 ``` Result: `latestNewtVersion = "v1.10.3"` instead of `"1.11.0"` - `semver.lt("1.10.1", "v1.10.3")` → true (correct for 1.10.1 sites) - `semver.lt("1.10.3", "v1.10.3")` → false (wrong — 1.11.0 is available) **Bug 2 (secondary): Cache invalidation without fallback** The cached version has a 1-hour TTL.
