Two write-path cache bugs surfaced during Gate 2 live testing:
P1 (delete didn't work / ghost event): syncCalendar only UPSERTED events
present on Fastmail and never removed cache rows for events that disappeared.
A successful CalDAV delete left the row in calendar_events forever, so
GET /api/events kept returning it and the UI showed a ghost that 'wouldn't
delete' (even after refresh). Add a prune step: delete calendar_events rows for
this calendar whose uid is absent from the server response (scoped to cal.id so
it never touches another calendar or the other member's rows — BUG B). Empty
server result prunes the whole calendar's cache.
P2 (edit needed a manual refresh): the outbox worker marked a row 'done' BEFORE
triggerTargetedResync refreshed the cache. The PWA's SyncStateToast invalidates
['events'] the instant sync-status flips to 'done', so it refetched stale cache.
Re-sync first, then mark done — 'done' now guarantees the cache reflects the write.
Tests: +2 prune regressions (present-subset prune, empty-server prune-all).
BUG A — timed events written 4h off: EventForm sent a naive local wall-clock
string with no offset; the UTC API container parsed it via new Date() as UTC, so
09:00 America/Toronto serialized to DTSTART:...090000Z. Fix: new
apps/pwa/src/lib/eventDateTime.ts serializes timed events to an unambiguous UTC
instant in the browser (where the operator's zone is known); all-day stays a DATE
string. No backend change.
BUG B — created events attached to the wrong user's calendar + duplicate calendar
rows per poll: calendars had no unique key on url, and poller/sync matched
calendars by url alone — so under the shared single Fastmail account (D-16) one
member's collection resolved to the other member's row. Fix: composite
unique(user_id, url); scope poller lookup + sync select to (userId, url); hand
migration 0001 (dedup + add key), applied to the live DB.
Regression tests fail against the buggy url-only predicate. API 98/98, PWA 140/140,
tsc clean both packages.
- Use ICAL.Event.isRecurring() (parity with expand.ts) to detect RRULE/RDATE
- Add hasRrule to .values() INSERT and .onDuplicateKeyUpdate() SET so the flag
is set on first sync and self-heals on every subsequent re-sync
- Without this fix every event had has_rrule=0 (column default), causing the
events route recurring-master pre-filter to return zero recurring occurrences
- Add sync.test.ts cases: hasRrule=true for timed+all-day recurring VEVENTs,
hasRrule=false for non-recurring, and hasRrule in onDuplicateKeyUpdate.set
- Use separate mock functions for insert/select chain to enable per-test assertions
- Reset mock implementations in beforeEach after vi.clearAllMocks
- Mock returns {id:42} from select (calendar ID for event upsert)
- 6 tests: all-day DATE vs timed TIMESTAMP, allDay flag, upsert on dup UID, rawVevent blob, ctag update
- Mocks db singleton at module level with vi.mock hoisting pattern
- Uses SAMPLE_VEVENT_TIMED/ALLDAY fixtures from tests/helpers/db.ts
- RED gate: all fail (src/broker/sync.ts does not exist yet)
