Added new status values for the IDL stuff.
2000-04-30 Federico Mena Quintero <federico@helixcode.com> * backend/ebook/e-book-types.h (EBookStatus): Added new status values for the IDL stuff. * backend/pas/pas-book-factory.h (PASBookFactoryClass): New "last_book_gone" signal. * backend/pas/pas-book-factory.c (pas_book_factory_launch_backend): Better error handling. (pas_book_factory_process_queue): Let pas_book_factory_process_request() free the request. (pas_book_factory_process_request): Free the request here. Perform better error handling. (free_active_server_map_entry): Free an active server map entry; free the URI key and unref the backend value. This function was renamed; the old one was trying to CORBA_Object_unref() a GTK+ object! (remove_backends_entry): Free a backend table entry; free the URI key. (backend_last_client_gone_cb): Remove the backend from the active server map and emit the "last_book_gone" signal if appropriate. (pas_book_factory_get_n_backends): New function to query the number of running backends in an addressbook factory. * backend/idl/addressbook.idl (BookListener::CallStatus): Added a ProtocolNotSupported code. This is for when the addressbook factory cannot find a provider for the requested URI. * backend/pas/pas-backend.h (PASBackendClass): New "last_client_gone" signal. (PASBackendClass): New get_uri virtual method. * backend/pas/pas-backend.c (pas_backend_load_uri): Return a gboolean success code. (pas_backend_add_client): Return a gboolean success code. (pas_backend_last_client_gone): New function used by backend implementations to notify upwards when the backend's last client is destroyed. (pas_backend_get_uri): New function to get the URI of a backend. * backend/pas/pas-backend-file.c (pas_backend_file_add_client): Pass the backend as the closure data to the "destroy" handler of the book. We cannot call pas_book_get_backend() in the callback since the book's private data has already been destroyed when the callback is invoked. Alternatively, we could move the private data destruction step to the book's ::finalize() method. (pas_backend_file_book_destroy_cb): Get the backend from the callback's data, not from the book. (pas_backend_file_remove_client): Remove the book from the list of clients. When all clients go away, call pas_backend_last_client_gone(). (PASBackendFilePrivate): Added an uri field. (pas_backend_file_get_uri): Implement the get_uri method. (pas_backend_file_load_uri): Return a gboolean success code. Also, store the URI in the private structure. (pas_backend_file_add_client): Return a gboolean success code. Also, call pas_backend_last_client_gone() if appropriate. (pas_backend_file_destroy): Free the bf->priv->uri. * backend/pas/pas-backend-ldap.c (pas_backend_ldap_add_client): Pass the backend as the closure data to the "destroy" handler of the book. See above for rationale. (pas_backend_ldap_book_destroy_cb): Get the backend from the callback's data. (pas_backend_ldap_remove_client): Remove the book from the list of clients.
