An 800 KB export imported nothing at all. Every event in the file went out
in a single CalendarEvent/set, and Stalwart refuses a method call carrying
more objects than maxObjectsInSet -- the whole call, with requestTooLarge,
creating none of it -- so the import failed at exactly the size that makes
importing worth doing. A two-event invitation was fine; a real calendar was
not.
The events now go out maxObjectsInSet at a time, which the client already
reads off the session and defaults to 500 where a server does not say. That
is the same ceiling and the same helper the mail store batches deletes and
flag changes by; nothing new had to be learned about the limit, and there is
no need to ask anyone to split an .ics by hand at an arbitrary line.
Still batches rather than a call per event: createEvent invalidates on the
way out and invalidating re-fetches every cached range, which is why the
import writes its own set calls in the first place. One invalidate, after
the last batch.
A batch that fails after earlier ones have been filed now says how many got
in -- "1000 of 1200 events were imported before this happened" -- and
re-reads the calendar so they are visible. Reporting only that the import
failed would send someone looking for events that are already there.
The mock enforced this ceiling all along, on both /get and /set; nothing had
exercised it with a file big enough to cross it.
Reported on #173.
