Update so as not to conflict with calendar (next_changed_item): update to
2000-12-06 JP Rosevear <jpr@helixcode.com>
* conduits/calendar/calendar-conduit.c (map_name): Update so as not to conflict
with calendar
(next_changed_item): update to use CalClientChange instead of CalObjChange
(compute_status): ditto
(pre_sync): ditto
(for_each_modified): since we now have the cal component we can call
local_record_from_comp directly
* conduits/todo/todo-conduit.c: same as above
* pcs/cal-backend.c: Remove much logging cruft
(cal_backend_compute_changes): Calculate the changes based on the
hashed database
(cal_backend_get_changes): call cal_backend_compute_changes
(cal_backend_compute_changes_foreach_key): hash callback for
calculating deletions
* pcs/cal-backend.h: update protype, remove logging cruft from
object
* pcs/cal.c (build_change_seq): dup the calobj rather than the uid
now
(Cal_get_changes): rename from Cal_get_changed_uids
(cal_get_epv): reflect name change in epv
* cal-util/cal-util.c (cal_obj_change_list_free): update assertion
* cal-util/cal-util.h: CalObjChange now returns the entire ical
component, update the change types. This should all go away shortly
* idl/evolution-calendar.idl: getChangedUIds -> getChanges.
CalObjChange now contains the calobj rather than the uid, update
the change types
* cal-client/cal-client.c (cal_client_get_changes): rename from
cal_client_get_changed_uids to make idl and addressbook
* cal-client/cal-client.h: Update prototype
* cal-client/cal-client.c (build_change_list): Build a list of
CalClientChange instead of CalObjChange
* cal-client/cal-client-types.c (cal_client_change_list_free): Free
a glist of CalClientChanges
* cal-client/cal-client-types.h: New file. Declarations for
CalClientChange.
* cal-client/Makefile.am: Build new files
