  26 ;; Access functions for the GVFS daemon from Tramp.  Tested with GVFS
  27 ;; 1.0 (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 (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 ;; With GVFS 1.14 (Ubuntu 12.10, Gnome 3.6) the interfaces have been
  37 ;; changed, again.  So we must introspect the D-Bus interfaces.
  38
  39 ;; All actions to mount a remote location, and to retrieve mount
  40 ;; information, are performed by D-Bus messages.  File operations
  41 ;; themselves are performed via the mounted filesystem in ~/.gvfs.
  42 ;; Consequently, GNU Emacs 23.1 with enabled D-Bus bindings is a
  43 ;; precondition.
  44
  45 ;; The GVFS D-Bus interface is said to be unstable.  There were even
  46 ;; no introspection data before GVFS 1.14.  The interface, as
  47 ;; discovered during development time, is given in respective
  48 ;; comments.
  49
  50 ;; The customer option `tramp-gvfs-methods' contains the list of
  51 ;; supported connection methods.  Per default, these are "dav",
  52 ;; "davs", "obex", "sftp" and "synce".  Note that with "obex" it might
  53 ;; be necessary to pair with the other bluetooth device, if it hasn't
  54 ;; been done already.  There might be also some few seconds delay in
  55 ;; discovering available bluetooth devices.
  56
  57 ;; Other possible connection methods are "ftp" and "smb".  When one of
  58 ;; these methods is added to the list, the remote access for that
  59 ;; method is performed via GVFS instead of the native Tramp
  60 ;; implementation.
  61
  62 ;; GVFS offers even more connection methods.  The complete list of
  63 ;; connection methods of the actual GVFS implementation can be
  64 ;; retrieved by:
  65 ;;
  66 ;; (message
  67 ;;  "%s"
  68 ;;  (mapcar
  69 ;;   'car
  70 ;;   (dbus-call-method
  71 ;;    :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
  72 ;;    tramp-gvfs-interface-mounttracker "listMountableInfo")))
  73
  74 ;; Note that all other connection methods are not tested, beside the
  75 ;; ones offered for customization in `tramp-gvfs-methods'.  If you
  76 ;; request an additional connection method to be supported, please
  77 ;; drop me a note.
  78
  79 ;; For hostname completion, information is retrieved either from the
  80 ;; bluez daemon (for the "obex" method), the hal daemon (for the
  81 ;; "synce" method), or from the zeroconf daemon (for the "dav",
  82 ;; "davs", and "sftp" methods).  The zeroconf daemon is pre-configured
  83 ;; to discover services in the "local" domain.  If another domain
  84 ;; shall be used for discovering services, the customer option
  85 ;; `tramp-gvfs-zeroconf-domain' can be set accordingly.
  86
  87 ;; Restrictions:
  88
  89 ;; * The current GVFS implementation does not allow to write on the
  90 ;;   remote bluetooth device via OBEX.
  91 ;;
  92 ;; * Two shares of the same SMB server cannot be mounted in parallel.
  93
  94 ;;; Code:
  95
  96 ;; D-Bus support in the Emacs core can be disabled with configuration
  97 ;; option "--without-dbus".  Declare used subroutines and variables.
