;;; Commentary:
;; Access functions for the GVFS daemon from Tramp. Tested with GVFS
;; 1.0.2 (Ubuntu 8.10, Gnome 2.24). It has been reported also to run
;; with GVFS 0.2.5 (Ubuntu 8.04, Gnome 2.22), but there is an
;; incompatibility with the mount_info structure, which has been
;; worked around.
;; It has also been tested with GVFS 1.6.2 (Ubuntu 10.04, Gnome 2.30),
;; where the default_location has been added to mount_info (see
;; <https://bugzilla.gnome.org/show_bug.cgi?id=561998>.
;; All actions to mount a remote location, and to retrieve mount
;; information, are performed by D-Bus messages. File operations
;; themselves are performed via the mounted filesystem in ~/.gvfs.
;; Consequently, GNU Emacs 23.1 with enabled D-Bus bindings is a
;; precondition.
;; The GVFS D-Bus interface is said to be instable. There are even no
;; introspection data. The interface, as discovered during
;; development time, is given in respective comments.
;; The customer option `tramp-gvfs-methods' contains the list of
;; supported connection methods. Per default, these are "dav",
;; "davs", "obex" and "synce". Note that with "obex" it might be
;; necessary to pair with the other bluetooth device, if it hasn't
;; been done already. There might be also some few seconds delay in
;; discovering available bluetooth devices.
;; Other possible connection methods are "ftp", "sftp" and "smb".
;; When one of these methods is added to the list, the remote access
;; for that method is performed via GVFS instead of the native Tramp
;; implementation.
;; GVFS offers even more connection methods. The complete list of
;; connection methods of the actual GVFS implementation can be
;; retrieved by:
;;
;; (message
;; "%s"
;; (mapcar
;; 'car
;; (dbus-call-method
;; :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
;; tramp-gvfs-interface-mounttracker "listMountableInfo")))
;; Note that all other connection methods are not tested, beside the
;; ones offered for customization in `tramp-gvfs-methods'. If you
;; request an additional connection method to be supported, please
;; drop me a note.
;; For hostname completion, information is retrieved either from the
;; bluez daemon (for the "obex" method), the hal daemon (for the
;; "synce" method), or from the zeroconf daemon (for the "dav",
;; "davs", and "sftp" methods). The zeroconf daemon is pre-configured
;; to discover services in the "local" domain. If another domain
;; shall be used for discovering services, the customer option
;; `tramp-gvfs-zeroconf-domain' can be set accordingly.
;; Restrictions:
;; * The current GVFS implementation does not allow to write on the
;; remote bluetooth device via OBEX.
;;
;; * Two shares of the same SMB server cannot be mounted in parallel.
;;; Code:
;; D-Bus support in the Emacs core can be disabled with configuration
;; option "--without-dbus". Declare used subroutines and variables.
