feat(presentations): notify support when a speaker or moderator changes on a published activity - #589
Merged

Conversation
…es on a published activity
Adds a stopgap email notification whenever a speaker or moderator is added
to or removed from an already-published presentation ("activity"), so
support staff can manually track promo-code/ticket fallout until the
automated sync described in the parent ticket exists.
New PresentationActivitySpeakerChangeEmail job (extends
AbstractSummitEmailJob) sent to a single platform-wide recipient read from
a new cfp.speaker_change_notification_email config value
(CFP_SPEAKER_CHANGE_NOTIFICATION_EMAIL) — no SummitEmailEventFlow entry,
per explicit product guidance that per-summit customization isn't needed
yet.
Dispatch is hooked at every place a published presentation's speaker/
moderator set changes:
- PresentationService::upsertPresentationSpeaker/removeSpeakerFromPresentation
(single add/remove admin endpoints), on a genuine state transition only.
- SummitService::addModerator2Presentation/removeModeratorFromPresentation
(self-service moderator assign/unassign).
- SummitService::saveOrUpdatePresentationData/saveOrUpdateEvent (bulk admin
"save presentation" form), diffing old vs. new speaker IDs and moderator.
All hooks are guarded by Presentation::isPublished() and dispatch only
after their surrounding transaction commits — discovered mid-implementation
that dispatching inline (which triggers AbstractSummitEmailJob's
getByIdRefreshed(), a mid-request Doctrine EntityManager::refresh()) can
corrupt entity state for later requests in the same process.
Explicitly out of scope: MemberService::registerExternalUserByPayload's
account-merge speaker reassignment (not a user-driven activity edit).
A pre-existing, unrelated Doctrine entity-staleness bug in
OAuth2PresentationApiController's PresentationSerializer admin-check
(commit 28ae095) was found during verification — reproduced identically
on unmodified code via git stash — and documented but not fixed here.

- Line 27: Update SummitService methods addSpeaker2Presentation and
removeSpeakerFromPresentation to dispatch PresentationActivitySpeakerChangeEmail
using the same post-commit transition handling as the adjacent moderator
endpoints, while preserving existing behavior for unpublished presentations.
- Around line 1933-1942: Update the moderator assignment flow around
setModerator() to capture the previous moderator before changing it and compare
moderator IDs. For published presentations, queue no notification when the
assignment is unchanged; when replacing an existing moderator, queue a Removed
notification for the previous moderator followed by an Added notification for
the selected speaker.
- Around line 868-872: Update the notification dispatch flow in updateEvents and
updateAndPublishEvents so PresentationActivitySpeakerChangeEmail::dispatch for
pending_speaker_changes occurs only after the enclosing bulk transaction
commits. Accumulate the changes at the outer operation boundary or register a
transaction-aware after-commit callback, ensuring rolled-back event updates
never enqueue notifications.

…nge notifications Three real gaps found by CodeRabbit's review of #589, all verified against current code before fixing: - SummitService::addSpeaker2Presentation/removeSpeakerFromPresentation (the self-service "my presentation" flow) never dispatched PresentationActivitySpeakerChangeEmail at all. Now guarded by isSpeaker() for genuine-transition-only, same pattern as PresentationService's version. - SummitService::addModerator2Presentation fired an unconditional "Added" notification on every call, even when reassigning the same moderator (no-op) or replacing an existing one (never notified the outgoing moderator). Now diffs old vs. new moderator: no notification when unchanged, Removed+Added when replaced. - updateEvents()/updateAndPublishEvents() wrap updateEvent() in an outer transaction; saveOrUpdateEvent() was dispatching right after its own *nested* transaction() call returned, but Doctrine's connection nests begin/commit via a counter, so that "commit" isn't real until the outermost transaction commits. A later item failing mid-batch rolled back an earlier item's DB changes while its notification had already gone out. Fixed by threading an optional by-reference $pending_notifications_out through saveOrUpdateEvent/updateEvent: bulk callers accumulate and dispatch only after their own outer transaction returns; standalone calls behave exactly as before. Root-caused while reproducing the last fix: DoctrineRepository::find() called EntityManager::refresh() unconditionally when $refresh=true, even when the lookup returned null - throwing a TypeError for any nonexistent ID passed to getByIdRefreshed(). DoctrineTransactionService::transaction() only catches \Exception, so that TypeError skipped rollback/cleanup entirely and left the DB transaction open indefinitely, holding locks across every table it had touched (reproduced live: a stuck transaction blocked the whole local DB for ~16 minutes until killed by hand). Fixed both: null-guard before refresh(), and widened the transaction service's catch to \Throwable so any future non-Exception error still rolls back and closes the connection. 11 new/extended tests covering all of the above, including a rollback regression test exercising the exact nested-transaction/failure path.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Fix rollback and cleanup ordering in the exception path.
Rollback must occur before closing the DBAL connection, because closing it resets the transaction nesting state and can cause the later rollback check to be skipped. Also initialize and guard $em before cleanup: if Registry::getManager() throws, the catch block currently attempts to use an unassigned entity manager and may skip manager reset. Please add regression coverage for the manager callback failure path.

…ion infra Revert the DoctrineRepository/DoctrineTransactionService changes from the previous commit - out of scope for an email-notifications PR, and nested-transaction/rollback handling in those exact files is already being reworked in #533. Redesign the batch-rollback regression test to trigger the mid-batch failure via an existing event with a nonexistent track_id (EntityNotFoundException, already null-checked) instead of a nonexistent event id (which went through DoctrineRepository::find()'s unguarded refresh() call - the bug reported separately on #533). Same coverage of SummitService's own dispatch-timing fix, without touching the file #533 owns.

1572-1577: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winReset pending notifications for each transaction attempt.
DoctrineTransactionService::transactioncan rerun its callback after a reconnectable exception. Because$pending_notificationsis initialized beforetransaction()and captured by reference, a failed attempt can leave entries in the array. A successful retry can append the same transitions again, causing duplicatePresentationActivitySpeakerChangeEmailjobs.Reset the accumulator at the start of each transaction callback, or collect attempt-local notifications and publish only the final attempt.
Proposed fix

…otification Speaker-change notifications are dispatched after the caller's transaction commits, so anything they throw surfaces as an HTTP error on a request whose write already landed. With cfp.speaker_change_notification_email unset — the default, since config/cfp.php has no fallback and .env.example ships the key blank — PresentationActivitySpeakerChangeEmail's constructor throws ValidationException, which RequestProcessor maps to a 412. Every speaker or moderator change on a published activity returned an error while persisting the change. Guard the dispatch loop instead: - skip and log when the recipient is not configured, so an unconfigured deployment simply sends nothing; - wrap each dispatch in try/catch, so one failing notification neither propagates nor cancels the rest of a bulk batch. Adds PresentationActivitySpeakerChangeEmail::RecipientConfigKey so the guard and the constructor read one key rather than two copies of the literal. Regression test asserts the endpoint returns 201, queues nothing, and really persists the speaker when the recipient is unconfigured. Verified red/green: reverting the guard reproduces the 412.

saveOrUpdateEvent decided whether to dispatch now or hand its pending notifications up to a bulk caller by testing `$pending_notifications_out !== null`. That made transactional semantics depend on whether the caller happened to INITIALIZE the out-param: passing an undeclared variable by reference yields null, which silently selects the dispatch-now branch and re-introduces the rolled-back-but-notified bug inside the outer transaction. It worked only because both call sites pre-initialized an array, and nothing enforced that. The root cause was updateEvent's double role - public entry point for the controllers and internal step of updateEvents/updateAndPublishEvents - so remove the double role instead of describing it with a flag. Introduce SpeakerChangeNotifications, a collector passed as a REQUIRED parameter. saveOrUpdateEvent and saveOrUpdatePresentationData only ever add to it; they never dispatch. Whoever constructs a collector is the one that dispatches it, right after its own transaction() returns - addEvent and updateEvent for the single paths, the bulk methods for their batch, which now call saveOrUpdateEvent directly rather than through updateEvent. Omitting the collector is a type error, not a null that quietly changes behaviour. The trait DispatchesSpeakerChangeNotifications is gone; its config guard and per-notification try/catch now live in the collector's dispatch(), which also empties itself so a double call cannot re-queue. updateEvent returns to its 5-parameter signature, so ISummitService:59 matches the implementation again with no change to the interface. Verified: OAuth2SummitEventsApiTest and OAuth2SummitSpeakersApiTest both match their pre-refactor results as full-file runs. Mutation-checked the invariant by routing the bulk loop back through updateEvent - the batch rollback regression test fails (2 queued, expected 0) and passes again once reverted.

Problem
As speakers change on published activities, it's difficult to track who may have used a promo code and is no longer on the schedule, or who needs one after accepted/rejected emails already went out (parent ticket 86b96e4te). There's no automated way to know a published presentation's speaker lineup changed.
Fix
Adds a stopgap notification email fired whenever a speaker or moderator is added to or removed from an already-published presentation ("activity"), sent to a single platform-wide support address — not per-summit, per explicit product guidance from JP Maxwell on the ticket (a single email for the platform is fine to start; per-summit config is an intentionally deferred future evolution).
PresentationActivitySpeakerChangeEmailjob (extendsAbstractSummitEmailJob), parametrized byrole(Speaker/Moderator) andaction(Added/Removed) rather than four near-identical job classes.cfp.speaker_change_notification_emailconfig value (CFP_SPEAKER_CHANGE_NOTIFICATION_EMAIL) — noSummitEmailEventFlowentry, since per-summit customization isn't needed yet.presentation_title,presentation_id, andsummit_name(auto-injected), matching JP's explicit request to identify where a change came from.PresentationService::upsertPresentationSpeaker/removeSpeakerFromPresentation— the single add/remove admin endpoints, only on a genuine state transition (not a no-op reorder/re-remove).SummitService::addModerator2Presentation/removeModeratorFromPresentation— self-service moderator assign/unassign.SummitService::saveOrUpdatePresentationData/saveOrUpdateEvent— the bulk admin "save presentation" form, which replaces the whole speakers array/moderator in one call; diffs old vs. new state to detect adds/removes.Presentation::isPublished()and defersdispatch()until after its surrounding transaction commits — discovered mid-implementation that dispatching inline (which triggersAbstractSummitEmailJob'sgetByIdRefreshed(), a mid-request DoctrineEntityManager::refresh()) corrupts entity state for later requests in the same process. A dispatched-then-rolled-back save would otherwise send a false notification.Deliberately out of scope:
MemberService::registerExternalUserByPayload's account-merge speaker reassignment — an automatic reconciliation side effect, not a user editing an activity.Test
tests/Unit/Jobs/PresentationActivitySpeakerChangeEmailTest— constructor validation (invalid role/action throwsInvalidArgumentException; unconfigured recipient throwsValidationException), all before touching the summit/presentation.tests/oauth2/OAuth2PresentationApiTest— add/remove speaker on published vs. non-published presentations, idempotency on repeat calls.tests/oauth2/OAuth2SummitSpeakersApiTest— moderator add/remove on published vs. non-published, and remove with no moderator set.tests/oauth2/OAuth2SummitEventsApiTest— bulk admin form save: speaker add+remove diff, moderator change diff, both on published and non-published presentations.All new/modified tests pass individually inside the Docker stack;
OAuth2SummitSpeakersApiTestandOAuth2SummitEventsApiTestalso pass as full-file runs.OAuth2PresentationApiTest's new tests are verified individually rather than batched — see note below.Note — pre-existing, unrelated bug found during verification:
tests/oauth2/OAuth2PresentationApiTest.phpfails ~6 pre-existing tests intermittently when run as a full 45-test file in one PHPUnit process, traced toPresentationSerializer's admin-check (28ae09584) hitting a stale Doctrine entity after enough sequential requests. Reproduced identically on this branch's base commit viagit stash, so it predates and is unrelated to this change. Not fixed here — flagged for its own investigation.Reviewed by the
