  26 ;; Access functions for the GVFS daemon from Tramp.  Tested with GVFS
  27 ;; 1.0.2 (Ubuntu 8.10, Gnome 2.24).  It has been reported also to run
  28 ;; with GVFS 0.2.5 (Ubuntu 8.04, Gnome 2.22), but there is an
  29 ;; incompatibility with the mount_info structure, which has been
  30 ;; worked around.
  31
  32 ;; It has also been tested with GVFS 1.6.2 (Ubuntu 10.04, Gnome 2.30),
  33 ;; where the default_location has been added to mount_info (see
  34 ;; <https://bugzilla.gnome.org/show_bug.cgi?id=561998>.
  35
  36 ;; All actions to mount a remote location, and to retrieve mount
  37 ;; information, are performed by D-Bus messages.  File operations
  38 ;; themselves are performed via the mounted filesystem in ~/.gvfs.
  39 ;; Consequently, GNU Emacs 23.1 with enabled D-Bus bindings is a
  40 ;; precondition.
  41
  42 ;; The GVFS D-Bus interface is said to be unstable.  There are even no
  43 ;; introspection data.  The interface, as discovered during
  44 ;; development time, is given in respective comments.
  45
  46 ;; The customer option `tramp-gvfs-methods' contains the list of
  47 ;; supported connection methods.  Per default, these are "dav",
  48 ;; "davs", "obex" and "synce".  Note that with "obex" it might be
  49 ;; necessary to pair with the other bluetooth device, if it hasn't
  50 ;; been done already.  There might be also some few seconds delay in
  51 ;; discovering available bluetooth devices.
  52
  53 ;; Other possible connection methods are "ftp", "sftp" and "smb".
  54 ;; When one of these methods is added to the list, the remote access
  55 ;; for that method is performed via GVFS instead of the native Tramp
  56 ;; implementation.
  57
  58 ;; GVFS offers even more connection methods.  The complete list of
  59 ;; connection methods of the actual GVFS implementation can be
  60 ;; retrieved by:
  61 ;;
  62 ;; (message
  63 ;;  "%s"
  64 ;;  (mapcar
  65 ;;   'car
  66 ;;   (dbus-call-method
  67 ;;    :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
  68 ;;    tramp-gvfs-interface-mounttracker "listMountableInfo")))
  69
  70 ;; Note that all other connection methods are not tested, beside the
  71 ;; ones offered for customization in `tramp-gvfs-methods'.  If you
  72 ;; request an additional connection method to be supported, please
  73 ;; drop me a note.
  74
  75 ;; For hostname completion, information is retrieved either from the
  76 ;; bluez daemon (for the "obex" method), the hal daemon (for the
  77 ;; "synce" method), or from the zeroconf daemon (for the "dav",
  78 ;; "davs", and "sftp" methods).  The zeroconf daemon is pre-configured
  79 ;; to discover services in the "local" domain.  If another domain
  80 ;; shall be used for discovering services, the customer option
  81 ;; `tramp-gvfs-zeroconf-domain' can be set accordingly.
  82
  83 ;; Restrictions:
  84
  85 ;; * The current GVFS implementation does not allow to write on the
  86 ;;   remote bluetooth device via OBEX.
  87 ;;
  88 ;; * Two shares of the same SMB server cannot be mounted in parallel.
