  22
  23 ;; Access functions for the GVFS daemon from Tramp.  Tested with GVFS
  24 ;; 1.0.2 (Ubuntu 8.10, Gnome 2.24).
  25
  26 ;; All actions to mount a remote location, and to retrieve mount
  27 ;; information, are performed by D-Bus messages.  File operations
  28 ;; themselves are performed via the mounted filesystem in ~/.gvfs.
  29 ;; Consequently, GNU Emacs 23.0.90 with enabled D-Bus bindings is a
  30 ;; precondition.
  31
  32 ;; The GVFS D-Bus interface is said to be instable.  There are even no
  33 ;; introspection data.  The interface, as discovered during
  34 ;; development time, is given in respective comments.
  35
  36 ;; The customer option `tramp-gvfs-methods' contains the list of
  37 ;; supported connection methods.  Per default, these are "dav", "davs"
  38 ;; and "obex".  Note that with "obex" it might be necessary to pair
  39 ;; with the other bluetooth device, if it hasn't been done already.
  40 ;; There might be also some few seconds delay in discovering available
  41 ;; bluetooth devices.
  42
  43 ;; Other possible connection methods are "ftp", "sftp" and "smb".
  44 ;; When one of these methods is added to the list, the remote access
  45 ;; for that method is performed via GVFS instead of the native Tramp
  46 ;; implementation.
  47
  48 ;; GVFS offers even more connection methods.  The complete list of
  49 ;; connection methods of the actual GVFS implementation can be
  50 ;; retrieved by:
  51 ;;
  52 ;; (message
  53 ;;  "%s"
  54 ;;  (mapcar
  55 ;;   'car
  56 ;;   (dbus-call-method
  57 ;;    :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
  58 ;;    tramp-gvfs-interface-mounttracker "listMountableInfo")))
  59
  60 ;; Note that all other connection methods are not tested, beside the
  61 ;; ones offered for customization in `tramp-gvfs-methods'.  If you
  62 ;; request an additional connection method to be supported, please
  63 ;; drop me a note.
  64
  65 ;; For hostname completion, information is retrieved either from the
  66 ;; bluez daemon (for the "obex" method), or from the zeroconf daemon
  67 ;; (for the "dav", "davs", and "sftp" methods).  The zeroconf daemon
  68 ;; is pre-configured to discover services in the "local" domain.  If
  69 ;; another domain shall be used for discovering services, the customer
  70 ;; option `tramp-gvfs-zeroconf-domain' can be set accordingly.
  71
  72 ;; Restrictions:
  73
  74 ;; * The current GVFS implementation does not allow to write on the
  75 ;;   remote bluetooth device via OBEX.
  76 ;;
  77 ;; * Two shares of the same SMB server cannot be mounted in parallel.
  78

  82 ;; option "--without-dbus".  Declare used subroutines and variables.
