/**
|
|
* Class to store all calendar data (storage object)
|
|
*
|
|
* Tables used by calendar_so:
|
|
* - egw_cal: general calendar data: cal_id, title, describtion, locations, range-start and -end dates
|
|
* - egw_cal_dates: start- and enddates (multiple entry per cal_id for recuring events!), recur_exception flag
|
|
* - egw_cal_user: participant info including status (multiple entries per cal_id AND startdate for recuring events)
|
|
* - egw_cal_repeats: recur-data: type, interval, days etc.
|
|
* - egw_cal_extra: custom fields (multiple entries per cal_id possible)
|
|
*
|
|
* The new UI, BO and SO classes have a strict definition, in which timezone they operate:
|
|
* UI only operates in user-time, so there have to be no conversation at all !!!
|
|
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
|
|
* SO operates only on server-time
|
|
*
|
|
* DB-model uses egw_cal_user.cal_status='X' for participants who got deleted. They never get returned by
|
|
* read or search methods, but influence the ctag of the deleted users calendar!
|
|
*
|
|
* DB-model uses egw_cal_user.cal_status='E' for participants only participating in exceptions of recurring
|
|
* events, so whole recurring event get found for these participants too!
|
|
*
|
|
* All update methods now take care to update modification time of (evtl. existing) series master too,
|
|
* to force an etag, ctag and sync-token change! Methods not doing that are private to this class.
|
|
*
|
|
* range_start/_end in main-table contains start and end of whole event series (range_end is NULL for unlimited recuring events),
|
|
* saving the need to always join dates table, to query non-enumerating recuring events (like CalDAV or ActiveSync does).
|
|
* This effectivly stores MIN(cal_start) and MAX(cal_end) permanently as column in main-table and improves speed tremendiously
|
|
* (few milisecs instead of more then 2 minutes on huge installations)!
|
|
* It's set in calendar_so::save from start and end or recur_enddate, so nothing changes for higher level classes.
|
|
*
|
|
* egw_cal_user.cal_user_id contains since 14.3.001 only an md5-hash of a lowercased raw email address (not rfc822 address!).
|
|
* Real email address and other possible attendee information for iCal or CalDAV are stored in cal_user_attendee.
|
|
* This allows a short 32byte ascii cal_user_id and also storing attendee information for accounts and contacts.
|
|
* Outside of this class uid for email address is still "e$cn <$email>" or "e$email".
|
|
* We use calendar_so::split_user($uid, &$user_type, &$user_id, $md5_email=false) with last param true to generate
|
|
* egw_cal_user.cal_user_id for DB and calendar_so::combine_user($user_type, $user_id, $user_attendee) to generate
|
|
* uid used outside of this class. Both methods are unchanged when using with their default parameters.
|
|
*
|
|
* @ToDo drop egw_cal_repeats table in favor of a rrule colum in main table (saves always used left join and allows to store all sorts of rrules)
