Alarm instance generation support for the Wombat.
2000-12-18 Federico Mena Quintero <federico@helixcode.com> Alarm instance generation support for the Wombat. * idl/evolution-calendar.idl (Cal::CalAlarmInstance): Changed to have an alarm UID, the trigger time, and the actual occurrence time. (Cal::CalComponentAlarms): New structure to hold a pair of a component and its alarms that trigger in a particular range of time. (Cal::getAlarmsInRange): Changed to return a CalComponentAlarmsSeq. * cal-util/cal-component.h (CalAlarmInstance): New C-side structure to match the one on the IDL. (CalComponentAlarms): Ditto. (CalAlarmAction): Renamed from CalComponentAlarmAction. (CalAlarmTriggerType): Renamed from CalComponentAlarmTriggerType. Encoded the START and END parameters for the RELATED parameter in this enum, too. Added a NONE value for invalid or missing trigger specifications. (CalComponentAlarmTriggerRelated): Removed. (CalAlarmTrigger): Renamed from CalComponentAlarmTrigger. Renamed the duration/time fields to rel_duration/abs_time, respectively. * cal-util/cal-component.c (cal_component_alarm_get_trigger): Changed to use the new trigger structure. (cal_component_alarm_set_trigger): Likewise. (cal_component_alarm_free_trigger): Removed function. (cal_component_has_alarms): Count the elements in the alarm_uid_hash instead of trying to fetch the first alarm subcomponent. (cal_component_alarms_free): New function to free a CalComponentAlarms structure. (CalComponentAlarmPrivate): Added an uid property pointer. (scan_alarm_property): Scan for the our extension UID property. (cal_component_alarm_get_uid): New function. * pcs/cal-backend.h (CalBackendClass): Changed the signatures of the ::get_alarms_in_range() and ::get_alarms_for_object() methods. * pcs/cal-backend.c (cal_backend_get_alarms_in_range): Changed signature; use the new method. (cal_backend_get_alarms_for_object): Likewise. * pcs/cal-backend-file.c (compute_alarm_range): New spiffy function to compute a range of time for alarm occurrences. (add_alarm_occurrences_cb): New function to add alarms for a particular occurrence of the component. (generate_absolute_triggers): New function to add the absolute alarm triggers. (generate_alarms_for_comp): New function to generate all the alarm instances for a component. (cal_backend_file_get_alarms_in_range): Implemented. * pcs/cal.c (Cal_get_alarms_in_range): Use the new CalBackend API. (Cal_get_alarms_for_object): Likewise. (build_alarm_instance_seq): Removed old function. * cal-util/cal-util.c (cal_alarm_instance_list_free): Removed function. * cal-client/cal-client.c (build_component_alarms_list): New function to demarshal the component alarms sequence. (build_alarm_instance_list): New function to demarshal the alarm instances sequence. (cal_client_get_alarms_in_range): Updated for the new API. (cal_client_get_alarms_for_object): Updated for the new API. * gui/gnome-cal.c: Temporary #ifdef-ing out of alarm-related stuff to make it build. svn path=/trunk/; revision=7076
