2007-12-11 David Zeuthen <davidz@redhat.com> Rework how volumes, drives and volume monitoring is done. Previosly the model was GDrive <1-1> GVolume where a GDrive instance represented a mount point and a GVolume instance represented a mounted file system. This patch changes it the model to GDrive <1-N> GVolume <1-1> GMount where GMount now serves the purpose of the old GVolume and the new GVolume serves the purpose of the old GDrive. In addition the new GDrive interface is used to represent a collection of GVolume instances (typically partitions) and also contains utility to query the state of the physical drive the GDrive object represents (such as checking for media, polling the drive, ejecting the media etc.). Also implement mounting and unmounting in the Unix volume monitor backend. A subquent patch will introduce GDrive support for ejection of media. * Makefile.am: * gdrive.c: (g_drive_is_media_check_automatic), (g_drive_is_media_removable), (g_drive_has_media), (g_drive_can_poll_for_media), (g_drive_eject), (g_drive_eject_finish), (g_drive_poll_for_media), (g_drive_poll_for_media_finish): * gdrive.h: * gfile.c: (g_file_find_enclosing_mount): * gfile.h: * gio.symbols: * glocaldirectorymonitor.c: (g_local_directory_monitor_constructor), (mounts_changed): * glocalfile.c: (get_mount_info), (g_local_file_find_enclosing_mount), (g_local_file_file_iface_init): * gnativevolumemonitor.h: * gunionvolumemonitor.c: (get_mounts), (get_volumes), (get_connected_drives), (g_union_volume_monitor_class_init), (child_volume_added), (child_volume_removed), (child_volume_changed), (child_mount_added), (child_mount_removed), (child_mount_pre_unmount), (child_mount_changed), (child_drive_changed), (g_union_volume_monitor_add_monitor), (g_union_volume_monitor_remove_monitor), (_g_mount_get_for_mount_path): * gunixmounts.c: (g_unix_is_mount_path_system_internal), (guess_system_internal), (_g_get_unix_mounts), (_g_get_unix_mount_points), (g_get_unix_mount_at), (g_unix_mount_free), (g_unix_mount_compare), (g_unix_mount_get_mount_path), (g_unix_mount_get_device_path), (g_unix_mount_get_fs_type), (g_unix_mount_is_readonly), (g_unix_mount_is_system_internal), (g_unix_mount_guess_type), (type_to_icon), (g_unix_mount_guess_name), (g_unix_mount_guess_icon), (g_unix_mount_point_guess_name), (g_unix_mount_point_guess_icon), (_canonicalize_filename), (_resolve_symlink), (_resolve_dev_root): * gunixmounts.h: * gunixvolume.c: (g_unix_volume_finalize), (_g_unix_volume_new), (_g_unix_volume_disconnected), (_g_unix_volume_set_mount), (_g_unix_volume_unset_mount), (g_unix_volume_get_icon), (g_unix_volume_get_name), (g_unix_volume_can_mount), (g_unix_volume_get_drive), (g_unix_volume_get_mount), (_g_unix_volume_has_mount_path), (mount_cb), (mount_read_error), (g_unix_volume_mount), (g_unix_volume_mount_finish), (g_unix_volume_volume_iface_init): * gunixvolume.h: * gunixvolumemonitor.c: (g_unix_volume_monitor_finalize), (get_mounts), (get_volumes), (get_connected_drives), (get_mount_for_mount_path), (g_unix_volume_monitor_class_init), (mountpoints_changed), (mounts_changed), (g_unix_volume_monitor_init), (_g_unix_volume_monitor_lookup_volume_for_mount_path), (find_mount_by_mountpath), (update_volumes), (update_mounts): * gunixvolumemonitor.h: * gvolume.c: (g_volume_get_mount), (g_volume_can_mount), (g_volume_mount), (g_volume_mount_finish): * gvolume.h: * gvolumemonitor.c: (g_volume_monitor_class_init), (g_volume_monitor_get_connected_drives), (g_volume_monitor_get_volumes), (g_volume_monitor_get_mounts): * gvolumemonitor.h: svn path=/trunk/; revision=6095
