This + * is, because in it's current state there is no elegant way to do this. + * The problem lies in the fact that a real CalDAV server with sharing support + * would first need email support (with invite notifications), and really also + * a browser-frontend that allows people to accept or reject these shares. + * + * In addition, the CalDAV backends are currently kept as independent as + * possible, and should not be aware of principals, email addresses or + * accounts. + * + * Adding an implementation for Sharing to standard-sabredav would contradict + * these goals, so for this reason this is currently not implemented, although + * it may very well in the future; but probably not before SabreDAV 2.0. + * + * The interface works however, so if you implement all this, and do it + * correctly sharing _will_ work. It's not particularly easy, and I _urge you_ + * to make yourself acquainted with the following document first: + * + * https://trac.calendarserver.org/browser/CalendarServer/trunk/doc/Extensions/caldav-sharing.txt + * + * An overview + * =========== + * + * Implementing this interface will allow a user to share his or her calendars + * to other users. Effectively, when a calendar is shared the calendar will + * show up in both the Sharer's and Sharee's calendar-home root. + * This interface adds a few methods that ensure that this happens, and there + * are also a number of new requirements in the base-class you must now follow. + * + * + * How it works + * ============ + * + * When a user shares a calendar, the updateShares() method will be called with + * a list of sharees that are now added, and a list of sharees that have been + * removed. + * Removal is instant, but when a sharee is added the sharee first gets a + * chance to accept or reject the invitation for a share. + * + * After a share is accepted, the calendar will be returned from + * getUserCalendars for both the sharer, and the sharee. + * + * If the sharee deletes the calendar, only their share gets deleted. When the + * owner deletes a calendar, it will be removed for everybody. + * + * + * Notifications + * ============= + * + * During all these sharing operations, a lot of notifications are sent back + * and forward. + * + * Whenever the list of sharees for a calendar has been changed (they have been + * added, removed or modified) all sharees should get a notification for this + * change. + * This notification is always represented by: + * + * Sabre\CalDAV\Notifications\Notification\Invite + * + * In the case of an invite, the sharee may reply with an 'accept' or + * 'decline'. These are always represented by: + * + * Sabre\CalDAV\Notifications\Notification\Invite + * + * + * Calendar access by sharees + * ========================== + * + * As mentioned earlier, shared calendars must now also be returned for + * getCalendarsForUser for sharees. A few things change though. + * + * The following properties must be specified: + * + * 1. {http://calendarserver.org/ns/}shared-url + * + * This property MUST contain the url to the original calendar, that is.. the + * path to the calendar from the owner. + * + * 2. {http://sabredav.org/ns}owner-principal + * + * This is a url to to the principal who is sharing the calendar. + * + * 3. {http://sabredav.org/ns}read-only + * + * This should be either 0 or 1, depending on if the user has read-only or + * read-write access to the calendar. + * + * Only when this is done, the calendar will correctly be marked as a calendar + * that's shared to him, thus allowing clients to display the correct interface + * and ACL enforcement. + * + * If a sharee deletes their calendar, only their instance of the calendar + * should be deleted, the original should still exists. + * Pretty much any 'dead' WebDAV properties on these shared calendars should be + * specific to a user. This means that if the displayname is changed by a + * sharee, the original is not affected. This is also true for: + * * The description + * * The color + * * The order + * * And any other dead properties. + * + * Properties like a ctag should not be different for multiple instances of the + * calendar. + * + * Lastly, objects *within* calendars should also have user-specific data. The + * two things that are user-specific are: + * * VALARM objects + * * The TRANSP property + * + * This _also_ implies that if a VALARM is deleted by a sharee for some event, + * this has no effect on the original VALARM. + * + * Understandably, the this last requirement is one of the hardest. + * Realisticly, I can see people ignoring this part of the spec, but that could + * cause a different set of issues. + * + * + * Publishing + * ========== + * + * When a user publishes a url, the server should generate a 'publish url'. + * This is a read-only url, anybody can use to consume the calendar feed. + * + * Calendars are in one of two states: + * * published + * * unpublished + * + * If a calendar is published, the following property should be returned + * for each calendar in getCalendarsForPrincipal. + * + * {http://calendarserver.org/ns/}publish-url + * + * This element should contain a {DAV:}href element, which points to the + * public url that does not require authentication. Unlike every other href, + * this url must be absolute. + * + * Ideally, the following property is always returned + * + * {http://calendarserver.org/ns/}pre-publish-url + * + * This property should contain the url that the calendar _would_ have, if it + * were to be published. iCal uses this to display the url, before the user + * will actually publish it. + * + * + * Selectively disabling publish or share feature + * ============================================== + * + * If Sabre\CalDAV\Property\AllowedSharingModes is returned from + * getCalendarsByUser, this allows the server to specify whether either sharing, + * or publishing is supported. + * + * This allows a client to determine in advance which features are available, + * and update the interface appropriately. If this property is not returned by + * the backend, the SharingPlugin automatically injects it and assumes both + * features are available. + * + * @copyright Copyright (C) 2007-2013 fruux GmbH (https://fruux.com/). + * @author Evert Pot (http://evertpot.com/) + * @license http://code.google.com/p/sabredav/wiki/License Modified BSD License + */ +interface SharingSupport extends NotificationSupport { + + /** + * Updates the list of shares. + * + * The first array is a list of people that are to be added to the + * calendar. + * + * Every element in the add array has the following properties: + * * href - A url.
