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
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>.
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
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.
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.
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
58 ;; GVFS offers even more connection methods. The complete list of
59 ;; connection methods of the actual GVFS implementation can be
67 ;; :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
68 ;; tramp-gvfs-interface-mounttracker "listMountableInfo")))
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
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.
85 ;; * The current GVFS implementation does not allow to write on the
86 ;; remote bluetooth device via OBEX.
88 ;; * Two shares of the same SMB server cannot be mounted in parallel.
92 ;; D-Bus support in the Emacs core can be disabled with configuration
93 ;; option "--without-dbus". Declare used subroutines and variables.
