What this does

PUT /api/v1/summits/{id}/attendees/all/send dispatched a single monolithic
ProcessAttendeesEmailRequestJob with tries=1/timeout=0, mirroring the same
architecture 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::triggerSend now resolves the matched attendee ids synchronously
(explicit attendees_ids payload, or a paginated getAllIdsByPage query), applies
excluded_attendees_ids, de-duplicates, and dispatches one
ProcessAttendeesEmailRequestJob per emails.attendees_process_job_chunk_size-sized
chunk (default 200, matching the speaker precedent) via JobDispatcher::withDbFallback.
The job gains the same ResumableChunkJob trait speakers use (tries=2, timeout
bounded strictly below every queue connection's retry_after) and a failed() hook
that logs the chunk's attendee ids and, when outcome_email_recipient was supplied,
sends an outcome excerpt naming them.

Two defects specific to this path, on top of the missing chunking:

  • No deterministic pagination. DoctrineRepository::getAllIdsByPage applied
    setFirstResult/setMaxResults with no ORDER BY, so paging through a filtered
    result 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 getParametrizedAllIdsByPage helper with a default
    ORDER BY e.id ASC, the same pattern DoctrineSpeakerRepository::getSpeakersIdsBySummit
    already uses.
  • No de-duplication proof. Unlike speakers, attendees had no per-recipient,
    per-email-type, timestamped record of a sent email, so a retry could not know who
    it already reached. New SummitAttendeeAnnouncementEmail entity mirrors
    SpeakerAnnouncementSummitEmail, adapted for the one shape speakers don't have:
    SummitAttendeeTicketEmailStrategy sends up to one email per ticket, not one per
    attendee, 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 AbstractEmailAction strategies (Generic, AllCurrentTickets,
RegistrationIncompleteReminder, Ticket) now check the sent-proof before
dispatching (skip if a retry already reached this attendee/ticket) and record it
after. AttendeeService::send's processCurrentId closure declared 8 parameters
while ParametrizedSendEmails invokes it with 9, silently dropping the info
callback used for resume-skip notifications — now declares and forwards all 9, in
the positional order _sendEmails uses (success, error, info), the same order
SpeakerService's closure declares.

Also fixes an N+1: Summit::getMainOrderExtraQuestionsByUsage() (the only caller is
SummitAttendee::getExtraQuestions(), on the invitation flow event) issued an
identical, uncached DQL query per attendee even though the same Summit PHP
instance is reused for every attendee in a chunk's send loop. Now memoized per
instance.

Deliberate behavior notes

  • attendees_process_job_chunk_size defaults to 200, not the initially-planned
    2000.
    The larger value would have meant fewer outcome-excerpt emails per large
    send, but was never validated against real per-attendee timing data — 200 matches
    the speaker precedent, which is running in production.
  • Zero-match sends dispatch nothing. Previously a single job still ran.
  • Duplicate explicit ids are de-duplicated before dispatch.
  • Explicit attendees_ids that belong to a different summit are skipped.
    send() loads each id with getByIdExclusiveLock (a bare find() by primary key)
    and nothing upstream verified the attendee belongs to the requested summit —
    auth.user only checks the endpoint's global groups, CurrentSummitFinderStrategy
    only 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.
  • One outcome excerpt e-mail per chunk — no cross-chunk aggregation (would need an
    all-chunks-finished signal this codebase doesn't have).
  • IAttendeeEmailFilterFields centralizes the FilterParser operator whitelist
    shared by the controller, triggerSend, and the job's 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 \App\Rules\Boolean() rule instances, and PHP
    does not allow new inside a class constant value — that validation array has
    exactly one consumer (the controller's own $filter->validate() call) and stays
    inline.

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 still json_encodes the
    whole payload (PII: test_email_recipient, outcome_email_recipient) — the feat(speakers): chunk the bulk speaker email send and unify the speaker filter whitelists #595
    finding to stop doing this was applied only to the service-layer trigger log.
  • No campaign-run identifier on the sent-proof — resume_since/send_date alone
    cannot distinguish two overlapping campaigns of the same flow event for the same
    summit.
  • The email dispatch and the proof write happen inside the same DB transaction — a
    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 of
scope per #598's own text ("platform-level, separate ticket").

Tests

  • tests/DoctrineSummitAttendeeRepositoryTest.php (new) — asserts the generated SQL
    carries an ORDER BY with no explicit Order (row-order assertions alone aren't a
    reliable RED signal here: MySQL commonly returns small tables in PK order anyway).
  • tests/SummitAttendeeAnnouncementEmailTest.php (new) — cascade persistence, the
    resume-check query matching on summit/type/date/ticket.
  • tests/AttendeeServiceResumeSendEmailsTest.php (new) — first attempt processes
    everyone; 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.
  • 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 Bus dispatches
    forced to throw; every chunk still gets attempted).
  • tests/ProcessAttendeesEmailRequestJobResumeTest.php (new) — resume_since
    activation on retry, timeout-below-retry_after regression guard.
  • tests/ProcessAttendeesEmailRequestJobFailedHookTest.php (new) — outcome excerpt
    on failure (with and without a recipient), database-queue failover, filter-field
    redaction.
  • tests/SummitExtraQuestionsMemoizationTest.php (new) — second call with the same
    usage issues no additional query.

Summary by CodeRabbit

  • New Features

    • Bulk attendee emails are processed in configurable batches for more reliable large-scale sending.
    • Retried email jobs resume safely, skipping recipients or tickets already processed.
    • Failed batches can send an attendee error report to a configured recipient.
    • Sent-email tracking improves prevention of duplicate attendee and ticket messages.
  • Bug Fixes

    • Attendee selection now handles exclusions and duplicate IDs consistently.
    • Paginated attendee results are ordered deterministically.
    • Repeated summit extra-question lookups are faster through result reuse.

…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.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 5ed82

Failed single-filter email chunks omit the filter field from diagnostics, making failures harder to investigate. This is a localized observability regression that should be corrected.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Wrap scalar filters before redacting their field names.

handle() passes $this->filter to utils\FilterParser::parse, which wraps scalar filters in an array. When a scalar filter such as email==jane@example.com reaches redactFilterFieldNames(), the current guard returns []. The failed-chunk log then omits filter fields, although this log contract requires field names without filter values.

♻️ Proposed change
     private function redactFilterFieldNames($filter): array
     {
-        if (empty($filter) || !is_array($filter)) return [];
-        return array_map(fn($condition) => preg_replace('/[=<>@!].*/', '', (string)$condition), $filter);
+        if (empty($filter)) return [];
+        if (!is_array($filter)) $filter = [$filter];
+        $conditions = array_filter($filter, 'is_scalar');

Comment thread app/Services/Model/AttendeeService.php
…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.

Pull request overview

Adds chunked, resumable bulk attendee email processing with sent-email proofs and deterministic selection.

Changes:

  • Chunks attendee email jobs with queue fallback and failure reporting.
  • Adds attendee/ticket sent proofs for retry-safe processing.
  • Adds ordered pagination, shared filters, and extra-question memoization.

Required change: AttendeeService.php:638Moderate (1 vote): Offset pagination across separate READ_COMMITTED transactions can still skip attendees when records change between pages. Use keyset pagination or a repeatable-read snapshot.
