new files to contain utility functions for calendar backends
2001-08-21 Rodrigo Moya <rodrigo@ximian.com>
* pcs/cal-backend-util.[ch]: new files to contain utility functions
for calendar backends
* pcs/cal-backend.c (cal_backend_add_cal): implement it here, and not in
the calendar backends. Add a "cal_added" signal, so that backends are
notified when a new Cal is added, if they need to
(cal_backend_get_type_by_uid): implement it here
* pcs/cal-backend-file.c (fill_alarm_instances_seq): moved to
cal-backend-util.c
(cal_backend_file_add_cal): removed
(cal_backend_file_init): connect to the "cal_added" signal in the
CalBackend class so that we can update categories when a new Cal is
added
(cal_backend_file_get_type_by_uid): removed
* pcs/cal-backend-db.c (fill_alarm_instances_seq): moved to
cal-backend-util.c
(cal_backend_db_add_cal): removed
(cal_backend_db_get_type_by_uid): removed
* AUTHORS: added JP and Damon to list of authors
svn path=/trunk/; revision=12339
