Four smaller calendar fixes found in review of the Stalwart 1.0 work.
- A range load that failed left `dateRange` on the range loaded before,
so a push or a pull-to-refresh reloaded that one instead of the range
on screen, and any action that reset `error` hid the "may be out of
date" notice. The store now takes the range asked for and keeps the
failure in `eventsLoadError`, which only a successful range load
clears.
- The agenda plugin's expanded query had no sort, so its limit could
keep later occurrences instead of the next ones. It now sorts by
start, looks less far ahead when the server refuses the range as too
long (`expandDurationTooLarge`, an administrator's shorter
`maxExpandedQueryDuration`) instead of answering 502, and sends its
gets several per request.
- With a limit (search, contact activity) the chunks of a long range
went out one request each. Up to four now share a request, and what
the later ones return past the limit is dropped. Global search passes
its AbortSignal down, so a replaced search stops between requests.
- A search of several words sends its date bounds as conditions of a
flat AND. The client did not see them as a range: it neither expanded
recurrences nor turned the UTC bounds into the request's wall clock,
so such a search found series instead of occurrences, over a range
shifted by the zone's offset. The bounds are now lifted out of the
AND, converted and chunked, and each chunk keeps one flat AND of
single conditions - the shape 1.0 expands; it refuses an AND holding
a condition with both bounds.
Stalwart 1.0 fails every CalendarEvent get and query whose `timeZone`
argument names a zone missing from its time zone database, with
invalidArguments "Invalid timeZone". 0.16 reads such a zone as UTC, so
the calendar kept working there; on 1.0 it would stay empty.
- check the user's zone with a get of no events that rides along with
the session's first calendar list
- once the server refuses the zone, ask in UTC, move the grid's
wall-clock range bounds to UTC as well, and log one console warning
- repeat a read that was refused before the check answered, once, in
UTC
Stalwart's change ids only grow. An upgrade that keeps the old change
log but restarts the counters lower (1.0 counts per collection where
0.16 counted per account) makes Email/changes and Mailbox/changes
accept an old state and answer with a lower `newState` and no changes,
so the delta sync would silently skip everything that changed since.
Read Stalwart `s` states (LEB128 in Stalwart's base32) and treat a
`newState` below `sinceState` like `cannotCalculateChanges`: fetch in
full. The check runs only on accounts that list `urn:stalwart:jmap`,
only for states in the exact form Stalwart writes, and never trips
while states go up.
Stalwart 1.0 refuses an expanded CalendarEvent/query longer than
maxExpandedQueryDuration (365 days by default) with
expandDurationTooLarge. The scrolling month view reaches 777 days and
search with after:/before: can span years, so the grid went blank.
Range queries are now split into chunks within the advertised limit and
merged. A chunk the server still refuses is halved; if a week still
expands to too many occurrences, the range is expanded in the browser
as before. 0.16 advertises the same limit without enforcing it and
returns the same events.
Stalwart 1.0 refuses a CalendarEvent/get that asks for
recurrenceOverrides together with utcStart or utcEnd, and every calendar
read did. The grid, tasks, reminders, search, contact activity and the
agenda plugin came back empty with no error, and creating an event or
task threw after the server had created it, so a retry made a
duplicate.
- read overrides with a second get in the same request, only where
they are needed
- treat an error answer to a get or query as a failure; the calendar
keeps the last events and says it could not load them, with a retry
- never throw after the server created an event or task
- let the server expand series for /api/calendar-agenda
