Calendar event import ics fails

Issues
1

Issue Description

I try to import an exported ics calendar file to stalwart. It fails with the error “Invalid calendar file format” in bulwark. I also tried to export the calendar and calenderevent using vandelay import and export function. For testing I created an empty calendar with a single event.

Expected Behavior

Import calenderevent from jmap exported stalwart server

Actual Behavior

warning: CalendarEvent local 1 skipped: connection error: malformed jmap response: unresolved local Calendar id 1 on export

Reproduction Steps

  1. Export calendar using vandelay
    ./vandelay import jmap --url https://mail.domain.private --auth-basic [email protected] --account-name [email protected] --objects calendar rene_test.sqlite -v
    import: Calendar …
    import: Calendar done (fetched=1 deleted=0 skipped=0 failed=0)
    Calendar: created=0 fetched=1 updated=0 deleted=0 skipped=0 failed=0

  2. Import calendarevents using vandelay
    ./vandelay import jmap --url https://mail.domain.private --auth-basic [email protected] --account-name [email protected] --objects calendarevent rene_test.sqlite
    import: CalendarEvent …
    import: CalendarEvent done (fetched=1 deleted=0 skipped=0 failed=0)
    CalendarEvent: created=0 fetched=1 updated=0 deleted=0 skipped=0 failed=0

  3. Remove calendarevent

  4. Export calendar and calendarevents using vandelay

Relevant Log Output

./vandelay export --url https://mail.domain.private --auth-basic [email protected] --account-name [email protected] --objects calendarevent rene_test.sqlite -vvv

The error happens because the calendarevent export run only included --objects calendarevent, which skips reconciling the parent Calendar container. Vandelay resolves calendar-event parent references through the container-to-target map that is built when calendars are reconciled first; if the calendar type isn’t part of the same export run, that map never gets built and the event’s local Calendar id can’t be resolved, producing “unresolved local Calendar id 1 on export”.

The fix is to include both types together (or omit --objects entirely to export everything in the archive):

vandelay export jmap --url https://mail.domain.private \
  --auth-basic [email protected] --account-name [email protected] \
  --objects calendar,calendarevent rene_test.sqlite -v

Container types (mailboxes, calendars, address books) must be reconciled in the same export pass as the items that belong to them, since parent references are resolved through the in-memory map built while processing containers in that run.
