||
;;; Commentary:
|
||
|
||
;; Access functions for the GVFS daemon from Tramp. Tested with GVFS
|
||
;; 1.0 (Ubuntu 8.10, Gnome 2.24). It has been reported also to run
|
||
;; with GVFS 0.2.5 (Ubuntu 8.04, Gnome 2.22), but there is an
|
||
;; incompatibility with the mount_info structure, which has been
|
||
;; worked around.
|
||
|
||
;; It has also been tested with GVFS 1.6 (Ubuntu 10.04, Gnome 2.30),
|
||
;; where the default_location has been added to mount_info (see
|
||
;; <https://bugzilla.gnome.org/show_bug.cgi?id=561998>.
|
||
|
||
;; With GVFS 1.14 (Ubuntu 12.10, Gnome 3.6) the interfaces have been
|
||
;; changed, again. So we must introspect the D-Bus interfaces.
|
||
|
||
;; All actions to mount a remote location, and to retrieve mount
|
||
;; information, are performed by D-Bus messages. File operations
|
||
;; themselves are performed via the mounted filesystem in ~/.gvfs.
|
||
;; Consequently, GNU Emacs 23.1 with enabled D-Bus bindings is a
|
||
;; precondition.
|
||
|
||
;; The GVFS D-Bus interface is said to be unstable. There were even
|
||
;; no introspection data before GVFS 1.14. The interface, as
|
||
;; discovered during development time, is given in respective
|
||
;; comments.
|
||
|
||
;; The custom option `tramp-gvfs-methods' contains the list of
|
||
;; supported connection methods. Per default, these are "afp", "dav",
|
||
;; "davs", "gdrive", "obex", "sftp" and "synce". Note that with
|
||
;; "obex" it might be necessary to pair with the other bluetooth
|
||
;; device, if it hasn't been done already. There might be also some
|
||
;; few seconds delay in discovering available bluetooth devices.
|
||
|
||
;; Other possible connection methods are "ftp" and "smb". When one of
|
||
;; these methods is added to the list, the remote access for that
|
||
;; method is performed via GVFS instead of the native Tramp
|
||
;; implementation.
|
||
|
||
;; GVFS offers even more connection methods. The complete list of
|
||
;; connection methods of the actual GVFS implementation can be
|
||
;; retrieved by:
|
||
;;
|
||
;; (message
|
||
;; "%s"
|
||
;; (mapcar
|
||
;; 'car
|
||
;; (dbus-call-method
|
||
;; :session tramp-gvfs-service-daemon tramp-gvfs-path-mounttracker
|
||
;; tramp-gvfs-interface-mounttracker "listMountableInfo")))
|
||
|
||
;; Note that all other connection methods are not tested, beside the
|
||
;; ones offered for customization in `tramp-gvfs-methods'. If you
|
||
;; request an additional connection method to be supported, please
|
||
;; drop me a note.
|
||
|
||
;; For hostname completion, information is retrieved either from the
|
||
;; bluez daemon (for the "obex" method), the hal daemon (for the
|
||
;; "synce" method), or from the zeroconf daemon (for the "afp", "dav",
|
||
;; "davs", and "sftp" methods). The zeroconf daemon is pre-configured
|
||
;; to discover services in the "local" domain. If another domain
|
||
;; shall be used for discovering services, the custom option
|
||
;; `tramp-gvfs-zeroconf-domain' can be set accordingly.
|
||
|
||
;; Restrictions:
|
||
|
||
;; * The current GVFS implementation does not allow writing on the
|
||
;; remote bluetooth device via OBEX.
|
||
;;
|
||
;; * Two shares of the same SMB server cannot be mounted in parallel.
|
||
