Connect to the Cal's destroy signal. (cal_backend_remove_cal): Killed
2000-02-10 Federico Mena Quintero <federico@helixcode.com>
* cal-backend.c (cal_backend_add_cal): Connect to the Cal's
destroy signal.
(cal_backend_remove_cal): Killed function now that removal of Cal
objects is done in their destroy callback.
(cal_destroy_cb): New callback to remove a Cal from the backend's
list of clients. Also, the backend destroys itself when there are
no more clients connected to it.
(save): New placeholder function to save a backend.
(destroy): New function to destroy a backend's data.
(cal_backend_destroy): Save the calendar and destroy it.
* cal.c (cal_destroy): Reset the priv->backend to NULL.
* cal-factory.c (add_calendar_client): There is no need to call
cal_backend_remove_cal(); we can now just destroy the Cal object.
(create_fn): Make sure we always unref the URI.
(load_fn): Move the URI unref to the end of the function for
safety.
* cal-factory.c (add_calendar_client): Unref the Cal only if
notification of the listener was unsuccessful. Otherwise, the
calendar user agent (Listener side) keeps the reference.
* tl-test.c (list_uids): Free the calobj.
* cal-client.c (cal_loaded_cb): Use bonobo_object_unref() to get
rid of the listener.
(load_or_create): Likewise.
(destroy_factory): New function to get rid of the factory.
(destroy_listener): New function to get rid of the listener.
(destroy_cal): New function to get rid of the calendar client
interface object.
(cal_client_destroy): Free all resources.
(cal_client_get_object): CORBA_free() the calobj string. Boy, I
love memprof.
* cal-listener.c (cal_listener_destroy): Reset the priv->cal to
CORBA_OBJECT_NIL.
* cal-backend.c (cal_backend_remove_cal): Do not unref the Cal,
since the calendar user agent owns it.
(cal_backend_add_cal): Do not ref the Cal, since the calendar user
agent owns it.
* cal-factory.c (add_calendar_client): Use bonobo_object_unref()
to get rid of the calendar client interface object.
* calobj.c (ical_object_create_from_vobject): Duplicate the
default "PUBLIC" string.
2000-02-09 Federico Mena Quintero <federico@helixcode.com>
* cal-factory.c (cal_factory_load): Added documentation comment.
(load_fn): Do not print a message if the backend could not be
loaded due to a non-fatal error.
(queue_load_create_job): Moved the stuff from cal_factory_load()
to here. Now this function serves to queue load or create
requests.
(cal_factory_load): Use queue_load_create_job().
(cal_factory_create): Implemented; use queue_load_create_job().
(create_fn): New job handler for creating new calendars.
(create_backend): New function to create a new backend with a new
calendar.
(add_backend): New helper function to add backends to the
factory's hash table.
(load_backend): Use add_backend() instead of adding the backend by
ourselves.
* cal-client.c (load_or_create): Moved the functionality from
cal_client_load_calendar() to here, and added an option to create
a new calendar instead of loading an existing one.
(cal_client_load_calendar): Use load_or_create().
(cal_client_create_calendar): Implemented.
* cal-backend.c (cal_backend_create): Implemented.
* evolution-calendar.idl (LoadStatus): Added an IN_USE error for
create requests.
* cal-listener.h (CalListenerLoadStatus): Added CAL_LISTENER_LOAD_IN_USE.
* cal-listener.c (Listener_cal_loaded): Convert the IN_USE error.
* cal-client.h (CalClientLoadStatus): Added CAL_CLIENT_LOAD_IN_USE.
* cal-client.c (cal_loaded_cb): Handle CAL_LISTENER_LOAD_IN_USE.
* tl-test.c: New test program for the calendar client side; it
also exercises the server side by sending commands to it.
* Makefile.am: Added the tl-test program.
* tlacuache.gnorba: Updated.
* tlacuache.c (create_cal_factory): Use the right GOAD id.
* cal-client.c (cal_client_construct): Use the right GOAD id.
