…nation getAllIdsByPage applied setFirstResult/setMaxResults with no ORDER BY, so MySQL was free to return a different row order per page. Paging through a filtered result set could silently skip or repeat rows across pages. Route through the existing getParametrizedAllIdsByPage helper with a default ORDER BY e.id ASC fallback when no explicit Order is given - the same pattern DoctrineSpeakerRepository::getSpeakersIdsBySummit already uses. Affects all 8 services calling this shared method.
Attendees had no per-recipient, per-email-type, timestamped proof of a sent email - InvitationEmailSentDate only covers the invitation path and carries no type dimension. This is the prerequisite for a retry-safe bulk send (a resumed chunk needs to know who it already reached). SummitAttendeeAnnouncementEmail mirrors SpeakerAnnouncementSummitEmail, adapted for the one shape speakers don't have: SummitAttendeeTicketEmailStrategy sends up to one email per ticket, not one per attendee, so this carries an optional ticket association. SummitAttendee gains the EXTRA_LAZY collection, addAnnouncementEmail/ removeAnnouncementEmail, and hasAnnouncementEmailTypeSentSince - a bounded matching() query, not a full hydration.
…rategy AbstractEmailAction and its four concrete strategies (Generic, AllCurrentTickets, RegistrationIncompleteReminder, Ticket) now share a resume-check/record pattern backed by SummitAttendeeAnnouncementEmail: before dispatching, skip a recipient already reached by this run (resume_since set and a matching proof exists); after dispatching, record the proof. SummitAttendeeTicketEmailStrategy is the one shape speakers don't have - up to one email per ticket, not one per attendee - so the check/record happens per ticket, keyed on the flow_event requested at the top of the loop rather than the value the complete-branch transiently mutates mid-loop. AttendeeService::send's processCurrentId closure declared 8 params while ParametrizedSendEmails invokes it with 9, silently dropping the info callback; now declares and forwards all 9, plus resume_since read from the payload. This task alone changes no observable behavior - resume_since is only ever set once the chunk job (Task 4) exists to set it.
AttendeeService::triggerSend replaced the single unbounded ProcessAttendeesEmailRequestJob::dispatch(...) with the id-list chunk-loop pattern SpeakerService::triggerSendEmails already uses: resolve the full matched id set (explicit attendees_ids or a paginated filter query), dedup, drop excluded ids, then dispatch one job per attendees_process_job_chunk_size-sized group via JobDispatcher::withDbFallback (primary connection, database fallback, sync as a last resort - one chunk failing every tier does not block its siblings). ProcessAttendeesEmailRequestJob gains the ResumableChunkJob trait (tries=2, timeout=1200s, strictly below every queue retry_after) and calls activateResumeIfRetrying() so a retry resumes via Task 3's resume-skip rather than re-emailing everyone. IAttendeeEmailFilterFields centralizes the FilterParser operator allow-list shared by the controller, triggerSend, and the job's own retry-path parse - previously duplicated inline, about to be duplicated a third time. Carries only OPERATORS, not a VALIDATION_RULES constant like ISpeakerFilterFields: three of this endpoint's fields validate via "new Boolean()" rule instances, and PHP does not allow "new" inside a class constant value. attendees_process_job_chunk_size defaults to 200, matching the speaker precedent, rather than the originally-planned 2000 - the larger value was never validated against real per-attendee timing.
ProcessAttendeesEmailRequestJob::failed() mirrors ProcessSpeakersEmailRequestJob::failed(): once both ResumableChunkJob attempts are exhausted, log the chunk's attendee ids at error with the exception class and message, and - when outcome_email_recipient was supplied - dispatch a SummitAttendeeExcerptEmail naming them, routed through JobDispatcher::withDbFallback same as the chunk itself. Nothing else reports this loss beyond a queue_failed_jobs row. Filter values are redacted to field names only before logging. Summit::getMainOrderExtraQuestionsByUsage() gains an instance-level memo. It has exactly one caller (SummitAttendee::getExtraQuestions()) and the same Summit PHP instance is reused for every attendee in a chunk's send loop, so every attendee on the invitation flow event was issuing an identical, uncached DQL query. Collapses N queries per chunk to 1.
…e reporting ProcessAttendeesEmailRequestJobResumeTest mirrors ProcessSpeakersEmailRequestJobResumeTest (minus should_resend, which attendees don't use): first attempt sets no resume_since, a second attempt with dispatched_at sets resume_since, a second attempt without dispatched_at (pre-deploy-window chunk) sets none, and job timeout stays strictly below every queue connection's retry_after. Rounds out ProcessAttendeesEmailRequestJobFailedHookTest with the database-fallback failover case that was left out when the failed() hook itself landed: when the primary Bus dispatch of the outcome excerpt throws, it must retry on the database connection rather than losing the report. Red-green verified testHandleOnSecondAttemptSetsResumeSince by temporarily disabling activateResumeIfRetrying() - the test fails, then passes again once restored.
AttendeeServiceResumeSendEmailsTest and AttendeeServiceBulkSendChunkingTest already satisfied Task 7's requirements from Tasks 3 and 4 - both built alongside the production code they cover, TDD RED-first. The one gap: the filter-based selection test resolved the fixture's small attendee count in a single DB page (default page size 2000), so it never exercised the multi-page merge logic in triggerSend's id-resolution loop, despite the plan calling for a test that spans several pages - the exact scenario Task 1's ordering fix exists for. Renamed to testFilterBasedSelectionSpanningSeveralPagesCoversEveryMatchedIdExactlyOnce and forces the DB chunk size down to 1 for the duration of the test, so a page that is skipped, re-read, or overwritten instead of merged would break the exact-set assertion. Full plan-wide regression: 55 tests, 261 assertions across all 9 test files created or touched by this plan, plus the HTTP controller suite - one pre-existing failure (testRedeemPromoCodes, unrelated, confirmed against unmodified code in Task 1) and nothing else.
@var SummitAttendeeAnnouncementEmail[] described it as a plain array; at runtime it's a Doctrine Collection (implements Selectable), which is why matching() already works on it. Same PHPStan gap speakers had (PR #598, commit cab6991) for the equivalent $announcement_summit_emails property - matched here for parity. Docblock-only change, no behavior change.
Config::get('emails.attendees_process_job_chunk_size', 2000)'s
fallback literal still said 2000 after the default moved to 200 in
config/emails.php - dead code under normal operation (the key is
always defined), but a real inconsistency if that config entry were
ever removed. Found by the changes-review agent.
📝 WalkthroughWalkthroughThe attendee email flow now resolves and chunks attendee IDs, dispatches resumable jobs, records sent proofs, skips completed work on retries, and reports failed chunks. Shared filter operators, deterministic pagination, summit checks, repeatable-read scans, and per-usage memoization are also added. ChangesAttendee email delivery
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Bulk attendee email delivery now supports chunking and resumable sends, but the added regression test may fail static analysis because its email-excerpt facade call is not declared on the facade contract.

…s, not ERROR AttendeeService::send's processCurrentId closure declared its last two callbacks as ($onDispatchInfo, $onDispatchError), but ParametrizedSendEmails::_sendEmails passes them positionally as (success, error, info) - the order SpeakerService's closure already uses. Every resume-skip notice therefore reached the outcome excerpt through EmailExcerpt::addErrorMessage as an ERROR line, and every strategy error through addInfoMessage as an INFO line. Reorder the closure's parameters (and the inner use list) to match the positional contract, and add a test asserting a resumed run reports the skipped attendee as exactly one INFO line and no ERROR lines.

AttendeeService::send loaded each id with getByIdExclusiveLock - a bare find() by primary key - and nothing upstream verified that an explicit attendees_ids entry belongs to the summit the send was requested for: auth.user only checks the endpoint's global groups, and CurrentSummitFinderStrategy only resolves the summit. A foreign id was emailed under the wrong summit's context and, since the sent-proof was introduced, its proof row was stamped with the requesting summit's id. Guard right after the lock: when the attendee's summit differs from the requested one, log a warning, add one ERROR line to the outcome excerpt naming the attendee, and return before any side effect. Covered by a test that sends a summit-1 attendee id against summit 2 and asserts no email is pushed, no proof is written, and exactly one ERROR line is reported.

…tion AttendeeService::triggerSend and SpeakerService::triggerSendEmails paged the matching ids with LIMIT/OFFSET, opening one READ COMMITTED transaction per page. A row that was deleted or stopped matching the filter between two page reads shifted every later row left by one, silently dropping one recipient. Wrap the whole scan in a single root transaction at REPEATABLE READ so every page reads the same InnoDB snapshot. The transaction service defaults to READ COMMITTED, which takes a fresh snapshot per statement, so the level is passed explicitly. Reads only, no locks held; chunk dispatch stays outside the transaction. Regression test in both chunking test classes asserts, on the captured SQL, exactly one START TRANSACTION preceded by a REPEATABLE READ isolation statement across a multi-page scan.

…atrix No job in the integration-tests matrix runs the tests/ root, only its subdirectories and the explicitly listed files, so the attendee bulk-email test classes added by this branch and the speaker chunk/resume classes added by #595/#598 never executed in CI. Add two path-named shards, one per subject, listing those files. tests/AttendeeServiceTest.php stays out on purpose: its pre-existing testRedeemPromoCodes hardcodes summit id 24 and fails on a fresh database.

641-650: 🚀 Performance & Scalability | 🔵 TrivialNote the cost of one long-lived REPEATABLE READ read transaction.
The whole page scan now runs in one snapshot. For a summit with a large attendee set, the transaction stays open for the full scan. On MySQL/InnoDB this keeps the read view alive and delays undo-log purge. Consider monitoring the scan duration, or bounding it by keyset pagination on
e.idso the snapshot requirement disappears.🤖 Prompt for AI Agents

…k log ProcessAttendeesEmailRequestJob::failed() and ProcessSpeakersEmailRequestJob:: failed() log the filter's field names (never its values, which can be PII) so a lost chunk can be reproduced. redactFilterFieldNames() returned [] for anything that was not an array, but FiltersParams::getFilterParam() passes the raw request value through: filter[] arrives as an array, a bare filter= as a string, and FilterParser::parse accepts both by wrapping the scalar. A scalar filter therefore logged "filter fields []". Wrap a scalar into a one-element array before redacting, keep only scalar conditions, and reindex. Originally flagged by CodeRabbit on #600.

…summit AttendeeService::send built each attendee's email strategy with the root Summit that ParametrizedSendEmails::_sendEmails fetches once, outside the per-attendee transaction. After any attendee's transaction failed (a transient queue push error, a retryable DB error), DoctrineTransactionService cleared or replaced the EntityManager and that Summit became detached, so every later attendee's sent-proof failed at flush with "A new entity was found through the relationship 'SummitAttendeeAnnouncementEmail#summit'" - after its email had already been dispatched. A retried chunk then re-emailed everyone processed after the failure while the excerpt reported them as sent. Build the strategy with $attendee->getSummit(), the managed association of the attendee this transaction just loaded (same id, enforced by the summit guard right above), so the proof always references a live entity of the current EntityManager. Regression test: one failing dispatch mid-chunk, every later attendee still gets exactly one proof.
…n the excerpt AttendeeService::send caught any exception thrown while processing one attendee and only logged it, so the operator's outcome excerpt for a run that silently skipped an attendee read exactly like a clean one. The excerpt is the only signal the operator gets, and SpeakerService::send already routes the same failure to the ERROR callback. Call $onDispatchError with the exception message from that catch, matching the speaker path. Regression test: one failing dispatch mid-chunk produces exactly one ERROR line carrying the failure reason, while every other attendee is still reported as sent.
… tests need AttendeeServiceResumeSendEmailsTest and ProcessAttendeesEmailRequestJobFailedHookTest extended Tests\TestCase, the plain Laravel base that runs no seeder. Every mail job they push resolves its template through Summit::getEmailIdentifierPerEmailEventFlowSlug, which reads SummitEmailEventFlowType - a table that is empty on a database built from initial_schema.sql plus migrations, as CI does: the migrations that seed those types are pre-marked in initial_migrations.sql or return early without their parent flow. The job constructor then threw "missing template_identifier value", the catch swallowed it, and CI reported "pushed 0 times" / no proof written in 5 tests while the same shard passed locally against an already-seeded database. Extend ProtectedApiTestCase instead, as the four speaker equivalents do: its BrowserKitTestCase base runs SummitEmailFlowTypeSeeder once per process. It also inserts and clears the member fixture itself, so the classes' own member fixture calls are dropped. Validated against a fresh model database created the way the CI job creates it.

…ction SpeakerService::sendEmails built each speaker's email strategy, resume check, promo code strategy and assistance with the root Summit that ParametrizedSendEmails::_sendEmails fetches once, outside the per-speaker transaction. After any speaker's transaction failed - a speaker id that no longer exists throws EntityNotFoundException right there; a queue push or a retryable DB error can throw too - DoctrineTransactionService cleared or replaced the EntityManager and that Summit became detached, so every later speaker's sent-proof (and any promo code or assistance generated for it) failed at flush with "A new entity was found through the relationship 'SpeakerAnnouncementSummitEmail#summit'" after its email had already been dispatched. A retried chunk then re-emailed everyone processed after the failure. Re-resolve the summit from the current EntityManager at the top of the transaction: an identity-map hit on the normal path, one query only after a clear. Same defect and fix as the attendee path (d043893); speakers have no owning summit to read it from, hence the repository lookup. Regression test: a missing speaker id first in the chunk, the next speaker still gets its email and exactly one proof.

There was a problem hiding this comment.
This changes the generic getAllIdsByPage(), which 86bbugg1j explicitly puts out of scope: "Do NOT change the generic DoctrineRepository::getAllIdsByPage. It has 12 call sites across 8 services... The same defect exists there, but fixing it globally belongs to 86bbuggqv, which has to make that call for the other six bulk sends anyway." The ticket asks instead for an override in DoctrineSummitAttendeeRepository, mirroring DoctrineSpeakerRepository::getSpeakersIdsBySummit, and that override isn't in this PR.
The fix itself looks right — the fallback is correctly chained off $order rather than $filter (the bug d3bfdb6 fixed on the speaker side), so it only applies when no explicit order was supplied.
The concern is blast radius. Every subclass without its own override now gets an ORDER BY e.id ASC it didn't have:
PurgeSummitsMarkAsDeletedCommandSummitPromoCodeServiceSummitRSVPInvitationService(2 call sites)SummitRSVPServiceSummitSubmissionInvitationServiceSummitRegistrationInvitationServiceScheduleServiceAttendeeService(3 call sites, the ones this ticket is about)
Repositories that pass an explicit $order (DoctrineSummitEventRepository, DoctrineSpeakerRepository) are unaffected. So seven flows outside this ticket change result ordering and gain a sort this PR doesn't cover with tests — tests/DoctrineSummitAttendeeRepositoryTest.php exercises the attendee path only.
Two ways forward, both fine by me:
- Scope it down as the ticket asks — add
getAllIdsByPage()toDoctrineSummitAttendeeRepositoryand revert this file — leaving the global fix to 86bbuggqv, which owns the decision for the other six bulk sends. - Keep it global, but call it out explicitly in the PR description and on 86bbuggqv so that ticket doesn't re-do it, and confirm none of the seven other flows depend on the current (undefined) ordering.
Option 1 is what the ticket contracted for and keeps the risk inside this PR's test coverage. If you prefer 2, that's a reasonable call given the defect is real everywhere — it just needs to be a stated decision rather than a side effect.

What this does
PUT /api/v1/summits/{id}/attendees/all/senddispatched a single monolithicProcessAttendeesEmailRequestJobwithtries=1/timeout=0, mirroring the samearchitecture that silently lost 183 of 683 speakers on 2026-08-31 (#595, #598).
Attendee populations are typically several times larger than speaker populations,
so the same failure was more likely here, not less.
AttendeeService::triggerSendnow resolves the matched attendee ids synchronously(explicit
attendees_idspayload, or a paginatedgetAllIdsByPagequery), appliesexcluded_attendees_ids, de-duplicates, and dispatches oneProcessAttendeesEmailRequestJobperemails.attendees_process_job_chunk_size-sizedchunk (default 200, matching the speaker precedent) via
JobDispatcher::withDbFallback.The job gains the same
ResumableChunkJobtrait speakers use (tries=2, timeoutbounded strictly below every queue connection's
retry_after) and afailed()hookthat logs the chunk's attendee ids and, when
outcome_email_recipientwas supplied,sends an outcome excerpt naming them.
Two defects specific to this path, on top of the missing chunking:
DoctrineRepository::getAllIdsByPageappliedsetFirstResult/setMaxResultswith noORDER BY, so paging through a filteredresult set could silently skip or repeat rows across pages. Fixed at the shared
base class (affects all 8 callers: RSVP, RSVP invitations, registration invitations,
submission invitations, promo codes, schedule, the purge command, and attendees) —
routed through the existing
getParametrizedAllIdsByPagehelper with a defaultORDER BY e.id ASC, the same patternDoctrineSpeakerRepository::getSpeakersIdsBySummitalready uses.
per-email-type, timestamped record of a sent email, so a retry could not know who
it already reached. New
SummitAttendeeAnnouncementEmailentity mirrorsSpeakerAnnouncementSummitEmail, adapted for the one shape speakers don't have:SummitAttendeeTicketEmailStrategysends up to one email per ticket, not one perattendee, so the proof carries an optional ticket association and the resume check
is keyed on the flow event requested at the top of that strategy's loop — not the
value it transiently mutates mid-loop when an attendee is complete.
All four
AbstractEmailActionstrategies (Generic,AllCurrentTickets,RegistrationIncompleteReminder,Ticket) now check the sent-proof beforedispatching (skip if a retry already reached this attendee/ticket) and record it
after.
AttendeeService::send'sprocessCurrentIdclosure declared 8 parameterswhile
ParametrizedSendEmailsinvokes it with 9, silently dropping the infocallback used for resume-skip notifications — now declares and forwards all 9, in
the positional order
_sendEmailsuses (success, error, info), the same orderSpeakerService's closure declares.Also fixes an N+1:
Summit::getMainOrderExtraQuestionsByUsage()(the only caller isSummitAttendee::getExtraQuestions(), on the invitation flow event) issued anidentical, uncached DQL query per attendee even though the same
SummitPHPinstance is reused for every attendee in a chunk's send loop. Now memoized per
instance.

attendees_process_job_chunk_sizedefaults to 200, not the initially-planned2000. The larger value would have meant fewer outcome-excerpt emails per large

the speaker precedent, which is running in production.

auth.useronly checks the endpoint's global groups,CurrentSummitFinderStrategyonly resolves the summit — so a foreign id was emailed under the wrong summit's
context and, with the new sent-proof, its proof row would be stamped with the
requesting summit's id. Pre-existing gap, fixed here as its own commit: the guard
logs a warning, adds one ERROR line to the outcome excerpt naming the attendee, and
returns before any side effect. Not a privilege escalation (the group check already
allows any
summit_id) — an integrity fix.all-chunks-finished signal this codebase doesn't have).

Known gaps carried over from the speaker precedent (not introduced or fixed here)
Cross-checked this PR against the review findings on #595 and #598. Three CodeRabbit
findings remain open on the speaker code today (no commit ever addressed them) and
are inherited as-is by this identical architecture:
ProcessAttendeesEmailRequestJob::handle()'s debug log stilljson_encodes thewhole payload (PII:
test_email_recipient,outcome_email_recipient) — the feat(speakers): chunk the bulk speaker email send and unify the speaker filter whitelists #595finding to stop doing this was applied only to the service-layer trigger log.
resume_since/send_datealonecannot distinguish two overlapping campaigns of the same flow event for the same
summit.
rollback after dispatch but before the proof commits would leave an email sent
with no durable record of it.
JobDispatcher::withDbFallback's own dispatch-idempotency is explicitly out ofscope per #598's own text ("platform-level, separate ticket").
Tests
tests/DoctrineSummitAttendeeRepositoryTest.php(new) — asserts the generated SQLcarries an
ORDER BYwith no explicitOrder(row-order assertions alone aren't areliable RED signal here: MySQL commonly returns small tables in PK order anyway).
tests/SummitAttendeeAnnouncementEmailTest.php(new) — cascade persistence, theresume-check query matching on summit/type/date/ticket.
tests/AttendeeServiceResumeSendEmailsTest.php(new) — first attempt processeseveryone; a resumed run skips only the attendee with a proof since dispatch and
doesn't duplicate it; a proof from an earlier campaign doesn't block a new one; the
multi-ticket case (2+ tickets, one already proofed) skips only that ticket; a
resumed run reports the skip as an INFO line, not an ERROR line, in the excerpt; an
explicit id from another summit is skipped with no email, no proof, and exactly one
ERROR line naming it; one failing dispatch mid-chunk still records exactly one proof
for every later attendee, and shows as exactly one ERROR line carrying its reason while
the others are still reported as sent.
tests/AttendeeServiceBulkSendChunkingTest.php(new) — chunk partitioning, exact-boundary count, empty match, exclusion, de-duplication, payload pass-through,
filter-based selection spanning several DB pages (chunk size forced to 1) covering
every matched id exactly once, and chunk-failure isolation (all
Busdispatchesforced to throw; every chunk still gets attempted).
tests/ProcessAttendeesEmailRequestJobResumeTest.php(new) —resume_sinceactivation on retry, timeout-below-retry_after regression guard.
tests/ProcessAttendeesEmailRequestJobFailedHookTest.php(new) — outcome excerpton failure (with and without a recipient), database-queue failover, filter-field
redaction.
tests/SummitExtraQuestionsMemoizationTest.php(new) — second call with the sameusage issues no additional query.
tests/SpeakerServiceResumeSendEmailsTest.php(existing) — a missingspeaker_idfirst in the chunk, the next speaker still gets its email and exactly one proof.
