Subject: New struct to wrap instances of calendar objects for recurrencies and

2000-02-08  Federico Mena Quintero  <federico@helixcode.com>

	* evolution-calendar.idl (CalObjInstance): New struct to wrap
	instances of calendar objects for recurrencies and alarms.
	(Cal::get_events_in_range): New method to get ocurring and
	recurring events by time range.

	* cal-backend.c (cal_backend_get_events_in_range): New function to
	get a list of event instances in a time range.
	(string_from_ical_object): New internal function.
	(cal_backend_get_object): Use string_from_ical_object() instead of
	doing everything ourselves.
	(cal_backend_get_events_in_range): New function to get a list of
	the events that occur or recur in a specified time range.

	* cal-client.c (cal_client_get_events_in_range): Implemented
	client-side function.

	* cal-util.h:
	* cal-util.c: New files with utilities and types common to the
	client and server parts.
	(CalObjInstance): New structure to hold an instance of an actual
	occurrence, recurrence, or alarm trigger of a calendar object.
	(cal_obj_instance_list_free): New function to free a list of
	calendar object instances.

	* cal.c (Cal_get_events_in_range): Implemented new method.

	* corba-cal.c (cal_repo_get_updated_objects): Free `str' with
	free(), not g_free(), since calendar_get_as_vcal_string() uses
	writeMemVObject(), which uses realloc().  Fixed in gnome-pim as
	well.
