Sender: followers-only Create deliveries carry a signed
Collection-Synchronization header scoped to the authority of each inbox,
and the partial followers collection is served to authenticated instances
at /users/{username}/followers_synchronization.
Receiver: a signed Collection-Synchronization header whose digest differs
from our copy queues FollowersSyncPipeline, which fetches the partial
collection as the instance actor and reconciles followers, pending follow
requests and unknown follows.
Adds profiles.followers_url for the collectionId check.
queueDelivery() runs synchronously from the v1 follow/unfollow endpoints
(via Helpers::sendSignedObject), which commit local state before delivery
and have no try/catch. After the Http::send() rewrite, a ConnectionException
from a momentarily-unreachable remote was rethrown out of queueDelivery(),
turning a best-effort delivery into a 500 for the user after the follow/
unfollow was already persisted. For unfollows, a retry then hit the
isFollowing==false branch and never re-sent the Undo, diverging state.
Treat transport failures (ConnectionException) as best-effort on this
single-delivery path: log, record host health, and return without
propagating. Other exception types (invalid sender/destination, signing,
serialization) still throw, matching pre-rewrite precondition behavior.
Also widen SendUpdateActor's per-user catch from HttpException to Throwable
so a single bad host no longer aborts a fleet-wide actor update (the old
HttpException catch is dead for ConnectionException/invalid-destination).
Add ActivityPubDeliveryService::pool() using Laravel's Http::pool() to
consolidate the duplicated delivery pattern found across 10 jobs.
Updated jobs:
- StatusActivityPubDeliver
- StatusDelete
- StatusLocalUpdateActivityPubDeliverPipeline
- FanoutDeletePipeline
- SharePipeline
- UndoSharePipeline
- StoryFanout
- StoryExpire
- StoryDelete
- ProfileMigrationDeliverMoveActivityPipeline
The shared method accepts a Profile (sender), audience (inbox URLs),
and activity (payload array), handling signing, user-agent, timeout,
and concurrency in one place. No direct Guzzle usage remains in
app/Jobs/.
Replace \Cache::, \Log::, \DB:: calls with their imported facade
equivalents. The backslash-prefix relies on global aliases which
PHPStan cannot resolve, causing class.notFound errors.
