Engine for live queries to calendars. A query object watches a
CalBackend in the PCS and is otherwise completely separate from
it; backends need to do nothing to support live queries. Right
now we have the following functions:
(get-vtype)
Returns a string indicating the type of component
(VEVENT, VTODO, VJOURNAL, VFREEBUSY, VTIMEZONE,
UNKNOWN).
(occur-in-time-range? START END)
START - int, time_t start of the time range
END - int, time_t end of the time range
Returns a boolean indicating whether the component
has any occurrences in the specified time range.
* idl/evolution-calendar.idl (Cal::getQuery): New method that
initiates a live query.
(Query): New interface for a handle to a live query.
(QueryListener): New interface for a listener to changes in a live
query.
* pcs/query.[ch]: New files with the live query engine.
* pcs/cal-backend.h (CalBackendClass): Added notification signals
so that the query system can catch them.
(CalBackendClass): New virtual method ::get_load_state().
* pcs/cal-backend.c (cal_backend_opened):
(cal_backend_obj_updated):
(cal_backend_obj_updated): New functions to emit the notification
signals; to be used only by backend implementations.
(cal_backend_get_load_state): New function.
* pcs/cal-backend-file.c (notify_update): Call
cal_backend_obj_updated().
(notify_remove): Call call_backend_obj_removed().
(open_cal): Free the icalcomp if it is not of the correct type.
(cal_backend_file_get_load_state): Implemented new method.
* pcs/cal-backend-db.c (cal_backend_db_update_object): Call
cal_backend_obj_updated().
(cal_backend_db_remove_object): Call cal_backend_obj_removed().
(cal_backend_db_get_load_state): Implemented new method.
* pcs/cal.c (Cal_get_query): Implementation of the ::getQuery()
method.
