📝 Walkthrough

Walkthrough

The change adds persisted domain throttling, list-exclusion filtering, atomic campaign claims, stale-campaign lookup, fallback requeueing, and related tests. Campaign processing now records exclusion, not-sent, sent-count, and sent-time data.

Changes

Messaging processing controls

Layer / File(s) Summary
Persisted domain throttling
.env.dist, config/..., src/Domain/Messaging/Model/DomainThrottleState.php, src/Domain/Messaging/Repository/DomainThrottleStateRepository.php, src/Domain/Messaging/Service/DomainRateLimiter.php, src/Migrations/..., tests/.../DomainThrottleStateRepositoryTest.php, tests/.../DomainRateLimiterTest.php
Adds configurable, database-backed per-domain quotas. Atomic reservations share quota state across workers. Auto-throttle can apply backoff after repeated blocked attempts.
Subscriber selection and exclusion lists
src/Domain/Subscription/..., tests/.../SubscriberRepositoryTest.php, tests/.../SubscriberProviderTest.php
Adds sendable-subscriber and exclude-list queries. Exclude-list members are removed from campaign recipients.
Atomic campaign processing and status handling
src/Domain/Messaging/Repository/MessageRepository.php, src/Domain/Messaging/MessageHandler/CampaignProcessor/..., src/Domain/Messaging/Model/Message/MessageMetadata.php, tests/.../MessageRepositoryTest.php, tests/.../CampaignProcessorMessageHandlerTest.php
Atomically claims submitted campaigns. Applies exclusions and throttling. Records user-message outcomes, sent timestamps, and sent counts.
Stuck-campaign lookup and fallback requeueing
src/Domain/Messaging/Service/Manager/MessageManager.php, src/Domain/Messaging/Service/Handler/RequeueHandler.php, tests/.../MessageManagerTest.php, tests/.../RequeueHandlerTest.php
Adds stale-campaign lookup and retries early-stopped campaigns after a one-minute fallback interval.

Priority: ➖ Normal — Schedule the email-sending change because it broadly alters campaign processing, recipient exclusions, domain throttling, and requeue behavior.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 0b8d1

Campaign recovery, worker capacity, and recipient-status records can fail under reachable processing conditions. These issues should be resolved before merge.

Move the atomic claim out of MessageRepository.

The checked-in src/Domain/** instruction prohibits raw executeStatement() DML outside the DynamicListAttr exception. tryClaimForProcessing() executes a conditional UPDATE, and MessageRepository is not DynamicListAttr-related. Move the claim operation to an Infrastructure or MessageHandler-level service while preserving its atomic condition.

Exercise the rolling-window reset with a positive period.

domainBatchPeriod: 0 makes DomainRateLimiter::canSendTo() return before calling currentBucket(), so the assertion checks only the non-positive-period bypass. Use a positive period and a controllable clock to verify that an exhausted bucket allows sending after the window expires. The repository requires coverage for new and fixed behavior.

Mark only excluded campaign recipients.

getExcludedSubscribers($excludeListIds) returns all exclusion-list members, not only the campaign’s sendable recipients. Compute the campaign’s recipient set before applying exclusions, then save Excluded UserMessage records only for its intersection with the exclusion lists.

Handle nullable UserMessage statuses before comparing them.

When an existing UserMessage has a NULL status, markExcludedSubscribers() calls UserMessageStatus::from(null) through getStatus(). This can throw a TypeError and abort the campaign. Make getStatus() null-safe, then define whether NULL means “preserve” or should be treated as Todo.

Move the throttle-state DBAL writes out of the Domain layer.

These methods execute UPDATE and INSERT statements in a non-DynamicListAttr repository under src/Domain/**. Move the DBAL implementation to Infrastructure or the application orchestration layer. Keep the Domain dependency as an interface that expresses slot-reservation intent.

As per path instructions, “Repositories in Domain should be abstractions without side effects; they should express intent, not perform flush/transactional logic.”

Restore a stale campaign to a claimable state before re-dispatch.

getStuckInProcessing() returns Prepared and InProcess campaigns. CampaignProcessorMessageHandler::__invoke() then calls tryClaimForProcessing(), which only claims Submitted campaigns. A re-dispatched stale campaign will therefore exit before processing.

Add an atomic stale-reclaim transition for these statuses, or reset the status to Submitted before dispatching the campaign.

Make auto-throttle backoff an atomic claim.

Concurrent workers can each receive a blocked result above the threshold before either resets the counter. Each worker then reaches sleep(). A busy domain can block many queue workers at once.

Make the repository atomically claim the backoff trigger and return the claimant. Only the claimant should reset the counter and sleep.
