Next review available in: 39 minutes Limit details: You’ve used all 2 included reviews currently available under your plan. You completed 80 included PR reviews in the past 7 days; at that activity level, included reviews refill at 2 reviews per hour. Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Included review availability: 1 review is currently available. Based on recent review activity, included reviews refill at 3 per hour. 📝 WalkthroughWalkthroughThe PR introduces key-selected OTA manifest verification, persistent metadata caching, platform-specific asset selection, updater option propagation, read-only selection-matrix validation, and signing/CDN workflow updates. ChangesOTA metadata verification
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The PR improves manifest caching, but the current implementation can expose updates before their minimum-version or rollout eligibility, creating unintended device updates. That release-gating defect should be fixed or explicitly accepted before merging; a separate filesystem-sync issue can also cause unnecessary repeated manifest downloads.

The client only sent If-None-Match, so the conditional GET never fired in production: Bunny does not generate ETags, it only forwards one the origin sends, and Bunny Storage sends none. Every check re-downloaded the whole manifest. Record Last-Modified alongside the ETag and send If-Modified-Since with it. Both are sent when known, since a server offering both prefers the ETag and it is the stronger validator. Also pins the behaviour when the CDN's manifest and signature objects disagree, which is possible for the length of their cache TTL after a republish because they are independent edge objects: the fresh signature wins over the cached bytes and the check fails closed, leaving the watermark and cache untouched.
The verification step's purpose is to confirm the edge serves the bytes we signed, but it fetched with ?cb= and no-cache headers, which aim at the origin instead. Both were inert — Bunny ignores request no-cache, and query strings are not part of the cache key on this zone, so a novel ?cb= still returns a HIT — so the step happened to do the right thing by accident. Fetch the plain URL a device requests. The purge before it is what makes the edge current, and the existing retry loop already covers purge propagation. Log each file's Cdn-Cache state on a mismatch: a HIT means the purge did not take, a MISS means the origin is serving something other than what was uploaded, and those have different fixes.

that CDN verification uses the plain device URL without cache-busting, and
document the Cdn-Cache diagnostics used to assess edge-cache behavior. Remove
the outdated claim that this step uses cache-busted requests.
In `@pkg/service/updater/otameta/manifest.go`:
- Around line 94-97: The releasesFor flow must enforce each manifest release’s
MinUpgradeFrom and Rollout before constructing selfupdate.HttpRelease values, so
Check and Apply only see eligible releases. Compare the minimum version with the
current version and assign a deterministic cohort for rollout percentages,

covering rollout 0 and MinUpgradeFrom.

error and return nil instead of propagating it. Keep rename errors fatal, and
broaden syncDir’s post-sync tolerance for platform/filesystem errors as needed,

Do not fail the write when only the directory sync fails.
os.Renameon line 209 already published the new contents. IfsyncDirthen returns an error,writeFileAtomicreports failure for a write that succeeded. Inpersist(pkg/service/updater/source.golines 161-183) that outcome clearsManifestETagandManifestLastModified, so the device refetches the whole manifest on every check even though the cache file is correct.The Windows carve-out on line 224 also only tolerates
os.ErrPermission. Directory handle sync fails with other errors on some platforms and filesystems, for exampleEINVALon certain network and overlay filesystems.Log a durability warning and return success after a successful rename.

Fix only still-valid issues, skip the rest with a brief reason, keep changes minimal, and validate. In `@pkg/service/updater/state.go` around lines 209 - 231, Update writeFileAtomic so a successful os.Rename remains successful even when syncDir fails: log the durability warning with the sync error and return nil instead of propagating it. Keep rename errors fatal, and broaden syncDir’s post-sync tolerance for platform/filesystem errors as needed, including non-permission directory-sync failures such as EINVAL.
Step 8 still described the re-fetch as cache-busted, which stopped being true when the verification step dropped the query string and the no-cache headers. Say what it does instead: the plain URL a device would request, through the edge, plus what a HIT or a MISS in the logged Cdn-Cache header means when it fails.
…flushed writeFileAtomic returned syncDir's error, so a filesystem that cannot flush a directory handle reported a successful write as a failure. Callers respond to that by discarding what they just stored: persist clears the cache validators and skips the generation watermark. On vfat and exFAT, which is what these devices run on, that would disable the conditional GET entirely and lose replay protection on every check. The rename has already happened by that point, so log the lost durability and return nil. Rename errors stay fatal.
Check and Apply each build their own transport and dropped it on return, leaving its keep-alive connections and their goroutines alive until the idle timeout expired. Return the updater and its transport together as a session so both callers can close it.
The ETag test inferred the conditional hit from a request count, and the missing-cache test only checked the rewritten cache was non-nil. Assert the server's 304 counter and compare the cache against the served bytes. TestManifest_ChannelNames claimed to guard the manifest's yaml field names against go-selfupdate's HttpManifest, which it never did. That guard is TestRun_ProducedManifestDecodesInGoSelfupdate, against a manifest the generator actually produced; point the comment at it and describe what this test does check.
…checks cacheValidators and httpResult sat between methods; they belong with verifiedSource at the top of the file. isReleaseArchive sliced by hand where strings.HasPrefix and strings.HasSuffix say the same thing.

1 participant
The manifest conditional GET never fired in production. The client sent only
If-None-Match, but Bunny does not generate ETags — it forwards one the originsends, and Bunny Storage sends none — so no file in the zone has an ETag and
every update check re-downloaded the full manifest.
Client
updaterStategainsManifestLastModified, andget()takes acacheValidatorspair instead of a bare etag string, sendingIf-None-Matchand
If-Modified-Sincewhen each is known. Both are kept because a serveroffering both prefers the ETag, and it is the stronger validator.
Also adds a test for the case where the CDN's manifest and signature disagree.
They are independent edge objects, so a republish leaves a window the length of
their cache TTL where the two can be out of step. The fresh signature wins over
the cached bytes: the check fails with
ErrBadSignatureand leaves thegeneration watermark and the cached manifest untouched. No retry — the stale
copy is on the edge, so refetching returns the same object, and the next
scheduled check recovers once the TTL lapses.
CI
The post-publish verification step exists to confirm the edge serves what we
signed, but fetched with
?cb=andCache-Control: no-cache, which target theorigin instead. Both are inert: Bunny ignores request
no-cache, and querystrings are not part of the cache key on this zone, so a novel
?cb=returns aHIT. The step was doing the right thing by accident. It now fetches the plainURL a device requests, and logs each file's
Cdn-Cachestate on a mismatch so astale
HIT(purge did not land) is distinguishable from aMISS(origin iswrong).
Server-side configuration
Done outside the repo, on the pull zone.
manifest.yamlandmanifest.yaml.sigwere not being edge-cached at all: Bunny's Smart Cache only caches a fixed
extension list, which includes
.txtbut not.yamlor.sig, so both weretreated as dynamic and passed through to origin on every request. An Edge Rule
with the Override Cache Time action (300s) plus a
Content-Type: text/plainresponse header now has them cached and compressed like
checksums.txt.Verified against
updates.zaparoo.org:Cdn-Cache: HIT,Content-Encoding: gzip, 19,932 bytes on the wire instead of 82,129, and both files return 304 toIf-Modified-Since.Summary by CodeRabbit
