kvaps and lexfrei confirmed the diagnosis by tracing source-watcher
v2.1.0 (same code paths in v2.2.x / flux-aio latest, so a simple
version bump does not remove the need for this workaround):
* fluxcd's patch.Helper patches .status and .status.conditions as
SEPARATE apiserver requests, so an etcd timeout during first-
install load can land between them — leaving Inventory /
ObservedSourcesDigest persisted while the Ready-condition write
is lost.
* On the next reconcile the !hasDrifted branch returns before
touching conditions. The deferred summarizeStatus still runs and
adjusts the Reconciling condition, but it never promotes a
stuck Unknown Ready to True — that promotion only happens on the
successful hasDrifted path.
Two substantive changes prompted by the reviews:
1. Document the semantic change the workaround introduces on
PackageSource.status.conditions[Ready]. fluxcd/pkg/runtime/
conditions.Set writes condition.ObservedGeneration =
ag.Generation on EVERY condition mutation including the
Progressing/Unknown mark at the start of a rebuild. And
ArtifactGeneratorStatus does not expose an object-level
ObservedGeneration (only ReconcileRequestStatus is inlined).
So Generation-matching cannot distinguish 'current revision
fully processed' from 'rebuild in progress, previous
Inventory/digest still persisted' — meaning the predicate can
(and does) fire during a content-only regeneration (new OCI
revision, same .metadata.generation).
Net effect: PackageSource Ready no longer dips through Unknown
while a new revision is being processed; it now means 'valid
consumable artifacts exist' rather than 'the current revision
has been processed'. Kvaps flagged this as the better contract
for install/upgrade ordering (no InProgress flapping, and a
genuine regeneration failure still surfaces as Ready=False on
the successful hasDrifted path). Document it inline instead of
implying the workaround only fires in the stuck-status window.
2. Reworked the predicate signature to take the pre-resolved
Ready condition as a parameter. The caller was already doing
the FindStatusCondition lookup for the pass-through path, so
the helper no longer duplicates it (kvaps' nit).
Also refreshed the pre-existing comments:
* The 'early-exits before touching status again' step is now
correctly worded as 'returns before touching conditions again;
the deferred summarizeStatus never promotes a stuck Unknown
Ready to True'.
* Bug attribution now names the code paths ('!hasDrifted branch',
'summarizeStatus deferred'), notes that v2.1.0 and v2.2.x
('flux-aio latest') both ship the affected code, and carries a
TODO(remove once upstream is fixed) marker so the workaround
cannot silently outlive its cause.
Tests: existing 8 subtests updated to construct the ready condition
manually so the call matches the new signature, plus one new
subtest locking in the intentional 'content-only regeneration
predicate fires' behaviour so a future refactor that tightens the
predicate back to 'current revision processed' — which would
re-introduce the flapping — fails loudly. 9/9 pass.
