* fix: request registry tokens with the target repository scope
The image-update detector authenticated to registries by reusing the scope
echoed in the registry's GET /v2/ ping. That ping carries no repository
context, and ghcr.io answers it with a placeholder scope
(repository:user/image:pull), so the token was requested for the wrong
repository and rejected. Every ghcr.io-backed image (including lscr.io, which
delegates auth to ghcr.io) then failed its manifest lookup and was reported as
"Registry unreachable", while Docker Hub and quay.io kept working. Always
request a pull scope for the repository being checked rather than the echoed
placeholder.
Also report the actual failure cause: getRemoteDigestResult now distinguishes
an authentication failure, a rate limit (with retry-after), a missing image, a
registry error, and a genuinely unreachable registry, instead of collapsing
every failure into "Registry unreachable". getRemoteDigest stays a
digest-or-null wrapper so the update-preview path is unchanged, and
listRegistryTags shares the same token path so it now resolves on
ghcr.io/lscr.io too.
* fix: neutralize control characters in the registry digest error log
The error-path console.error in getRemoteDigestResult interpolated the image
ref and the caught error message, both of which originate from compose-authored
input. Route them through sanitizeForLog so a crafted image string or upstream
error text cannot forge multi-line log entries (log injection). The returned
reason and the digest logic are unchanged.
* fix: distinguish failed image-update checks from "up to date"
The image-update detector collapsed every failure (registry unreachable,
missing auth, rate limit, unresolved local digest) into hasUpdate:false and
dropped the captured reason, so a failed check was indistinguishable from a
current image and never raised a notification, even while a manual stack
update still pulled a newer image.
Detection now records a tri-state per stack (ok / partial / failed) with the
failure reason, exposed via a new GET /api/image-updates/detail (the boolean
GET / is unchanged so fleet aggregation is unaffected). A fully-failed check
preserves the last known has_update, so a transient outage neither erases a
real update nor flaps the notification state. The sidebar shows a muted
"couldn't check" indicator with the reason on hover, and the Update board
lists stacks whose check failed in a "could not be checked" advisory.
Detector hardening: the manifest digest lookup issues HEAD first (falling back
to GET) so it no longer draws down Docker Hub's anonymous pull-rate budget, and
local RepoDigest matching is normalized so official library/* images resolve
their digest instead of falling through to a silent "no update".
* fix: preserve confirmed updates through partial checks; tighten failure surfacing
Address review findings on the tri-state image-update detection:
- A partial check (some images errored) no longer erases a previously
confirmed update; only a fully-ok check can lower has_update, so a single
image's registry blip cannot drop the stack's update and re-fire the
notification on recovery. Adds a regression test.
- The image-level catch stores getErrorMessage(e) rather than raw String(e),
since that value surfaces verbatim in the sidebar tooltip and readiness
advisory.
- useImageUpdates and the readiness detail fetch now log unexpected non-ok
responses instead of silently leaving stale state.
- Remove an unused checkFailedCount derivation (the row indicator is driven by
the checkStatus prop).
- Reword the recordStackCheckFailure docstring and the HEAD-first comment.
