- send not invitations as calendar-events, just email meeting requests, as they double the events with z-push 2.5 and iOS 12.3
- send all participants incl. organizer as participants, as Exchange also does that and they are otherwise lacking on Android
- fix meeting requests without CLASS:PUBLIC got imported as private events
- better logging for ChangeMessage
Resource quantity is restored from existing event, as neither iOS nor Thunderbird returns our X-EGROUPWARE-QUANTITY attribute on the attendee. Also display quantity > 1 in brackets after resource name.
If secritary creates an event in the owners calendar the owner/organizer is on status NEEDS-ACTION.
Accepting that event in Thunderbird set PARTSTAT=ACCEPTED on ORGANIZER, while ATTENDEE is still on PARTSTAT=NEEDS-ACTION. In that case prefer the PARTSTAT from ORGANIZER over ATTENDEE.
In my opionion Thunderbird behavior is wrong, thought that fix does not do any other harm,
as no other client sets PARTSTAT in ORGANIZER.
Caused by no real floating date support in EGroupware and defaulting to UTC, if no timezone specified, because Horde_Icalendar does not report datetimes postfixed with Z as UTC.
Fixed now by not using UTC workaround for date (not datetime) values.
Also implemented default duration of one day for dtstart as date and no dtend/duration given.
current Horde_Icalendar only exports EXDATE in Zulu-time, so we can only remove timezone. Apple calendar on OS X 10.11.4 uses a timezone, so does Horde eg. for Recurrence-ID
- adding priority=0=undefined to calendar, as it is iCalendar default
- no longer export iCalendar defaults PRIORITY=0, TRANSP=OPAQUE, CLASS=PUBLIC
- assume UTC if no timezone given, unfortunatly Horde_Icalendar currently does not tell UTC or local
- export DURATION instead of DTEND for UTC and duration less or equal 1 day (todo: store if user entered duration in db model, to be able export it as such again)
- no longer decodes base64 automatic
- size param have to be string due to bug in handling of integers in Horde_Icalendar
- allow stripping of non-binary (eg. text/plain) inline attachments
- only add X-EGROUPWARE-ATTACH-INCLUDED, if we have a real managed attachment
- store external / url attachments as other unsupported attributes
caused by new Horde Icalendar class exporting all integer x-properties as empty string, casting X-EGROUPWARE-UID not explicit to string before passing it to Horde code
