25 ;; Access functions for the GVFS daemon from Tramp. Tested with GVFS
26 ;; 1.0.2 (Ubuntu 8.10, Gnome 2.24). It has been reported also to run
27 ;; with GVFS 0.2.5 (Ubuntu 8.04, Gnome 2.22), but there is an
28 ;; incompatibility with the mount_info structure, which has been
31 ;; It has also been tested with GVFS 1.6.2 (Ubuntu 10.04, Gnome 2.30),
32 ;; where the default_location has been added to mount_info (see
33 ;; <https://bugzilla.gnome.org/show_bug.cgi?id=561998>.
35 ;; All actions to mount a remote location, and to retrieve mount
36 ;; information, are performed by D-Bus messages. File operations
37 ;; themselves are performed via the mounted filesystem in ~/.gvfs.
38 ;; Consequently, GNU Emacs 23.1 with enabled D-Bus bindings is a
41 ;; The GVFS D-Bus interface is said to be instable. There are even no
42 ;; introspection data. The interface, as discovered during
43 ;; development time, is given in respective comments.
45 ;; The customer option `tramp-gvfs-methods' contains the list of
46 ;; supported connection methods. Per default, these are "dav",
47 ;; "davs", "obex" and "synce". Note that with "obex" it might be
48 ;; necessary to pair with the other bluetooth device, if it hasn't
49 ;; been done already. There might be also some few seconds delay in
50 ;; discovering available bluetooth devices.
52 ;; Other possible connection methods are "ftp", "sftp" and "smb".
53 ;; When one of these methods is added to the list, the remote access
54 ;; for that method is performed via GVFS instead of the native Tramp
57 ;; GVFS offers even more connection methods. The complete list of
58 ;; connection methods of the actual GVFS implementation can be
66 ;; :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
67 ;; tramp-gvfs-interface-mounttracker "listMountableInfo")))
69 ;; Note that all other connection methods are not tested, beside the
70 ;; ones offered for customization in `tramp-gvfs-methods'. If you
71 ;; request an additional connection method to be supported, please
74 ;; For hostname completion, information is retrieved either from the
75 ;; bluez daemon (for the "obex" method), the hal daemon (for the
76 ;; "synce" method), or from the zeroconf daemon (for the "dav",
77 ;; "davs", and "sftp" methods). The zeroconf daemon is pre-configured
78 ;; to discover services in the "local" domain. If another domain
79 ;; shall be used for discovering services, the customer option
80 ;; `tramp-gvfs-zeroconf-domain' can be set accordingly.
84 ;; * The current GVFS implementation does not allow to write on the
85 ;; remote bluetooth device via OBEX.
87 ;; * Two shares of the same SMB server cannot be mounted in parallel.
91 ;; D-Bus support in the Emacs core can be disabled with configuration
92 ;; option "--without-dbus". Declare used subroutines and variables.
