2005-01-10 Federico Mena Quintero <federico@ximian.com> Fix #162617. * gtk/gtkfilesystemunix.c (STAT_NEEDED_MASK): Take out GTK_FILE_INFO_IS_HIDDEN; we don't need to stat() to know this. (gtk_file_system_unix_get_folder): Make error reporting more accurate. Don't bail out if we can't read the directory. (fill_in_stats): Don't return an error; just assume we don't have stat info for this folder's files. (fill_in_names): Don't create the hash table for the names if we can't open the directory. (gtk_file_folder_unix_list_children): Don't emit the "finished-loading" signal --- we don't do asynchronous loads, so we are always finished loading. (gtk_file_folder_unix_get_info): Use helper functions; handle the case where we can't stat '/'. (get_icon_type_from_path): Don't call fill_in_stats() here; only use the info we have. (fill_in_mime_type): Don't return an error. Don't do anything if we don't have the stat info.
