- Disabling Schedule-Tag handling completly, as current implementation seems to create too much trouble with iCal under OS X or iOS, which send If-Schedule-Tag-Match condition event for major updates, not just changing own status or alarms
+ do NOT use ORGANIZER for events without further participants or a different organizer
+ do not include event owner/ORGANIZER as participant in his own calendar, if he is only participant
--> all other cases include ORGANZIER and additional as ATTENDEE (tested with iCal on iOS and OS X)
- implemented schedule-tag and If-Schedule-Tag-Match header from CalDAV Scheduling
- allow to change participant status and add/remove alarms with schedule-tag instead of ETag
--> If-Schedule-Tag-Match header has precedence over If-Match (ETag) header, but limits changes to participant status and alarms
--> ToDo: test accepting, rejecting recurrences
- principal reports scheduling-inbox-URL /<username>/inbox/ and scheduling-outbox-URL /<username>/outbox/
- outbox collection contains no events
- outbox correctly answers POST for freebusy information
- outbox respons to all other POST with "204 No Content", ignore client request to deliver invitations
- inbox collection contains events of unknown status (PARTSTAT=NEEDS-ACTION)
- inbox responds to DELETE with "200 Ok"
--> iCal under OS X now shows freebusy times :-)
(had to add "write-content" privilege for calendar collections user has edit rights for, to allow adding events)
- sending alarms to CalDAV/GroupDAV clients as offset, not fixed time like before
- only exception to the above are alarms for recuring events to Lightning, which must be absolute, as offset lead to infinit poping up alarms in Lightning
- update all alarm times of other users alarms too, when storing events, as they might not be included in the stored event
- Lightning pops up alarm, until Sequence/etag get updated: if user has no edit rights on an other users calendar, etag never got updated, now we update it
- fixed user was not able to add alarms via CalDAV, if he had no edit rights for event (was always possible in web UI)
- alarms from other users calendars are not included any more, as they make no sense but a lot of trouble
- fixed wrong condition on adding alarms, causing some alarms no being saved
