1 D-Bus Python Bindings 0.82.2 (unreleased)
2 =========================================
6 * Connection.call_async() measures timeouts in seconds, as was always intended.
7 This means that calls through a proxy object with a reply_handler and
8 error_handler will measure the timeout in seconds too. call_blocking()
9 already used seconds, and still does. Existing code using timeouts for
10 async calls (which would only have worked with 0.82.1) will have to adjust
11 the timeout length. This applies to the OLPC Sugar environment as used in
12 Trial 2, for instance.
14 * Building against Python 2.4 on non-Debian-derived distributions, or a
15 non-default Python version on Gentoo, should work again (revenge
16 of fd.o #11282, thanks Eyal Ben David).
18 D-Bus Python Bindings 0.82.1 (2007-07-11)
19 =========================================
21 The "double precision" release.
25 * Parse the timeout correctly in send_message_with_reply() and
26 send_message_with_reply_and_block(), fixing the use of non-default timeouts
28 * The tutorial no longer uses interactive-Python syntax, as it confused users.
30 * When making a call via a proxy object with ignore_reply=True, also get the
31 necessary introspection data asynchronously. This can avoid deadlocks in
32 some cases, such as calling methods in the same process (though this is not
33 recommended, for efficiency and sanity reasons).
34 * dbus.lowlevel exposes enough constants to write correct filter functions.
35 * We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
36 is too old to have the modern replacement, dbus_watch_get_unix_fd().
40 * Omitting the bus argument in the BusName constructor is deprecated.
41 The fact that it uses the globally shared connection to the session bus by
42 default is uncomfortably subtle.
44 D-Bus Python Bindings 0.82.0 (2007-06-19)
45 =========================================
49 * dbus.service.Object can start off with no Connection or object path, and
50 become exported later. If suitable class attributes are set, objects can
51 even be exported on multiple connections, or with multiple object-paths,
54 * dbus.service.FallbackObject implements a whole subtree of object-path space
57 * ``@method`` accepts a parameter ``connection_keyword`` so methods can find
58 out which connection to use for any follow-up actions.
60 * ``@signal`` has a new parameter ``rel_path_keyword`` which gets the path at
61 which to emit the signal, relative to the path of the FallbackObject.
62 ``path_keyword`` is now deprecated, and will raise an exception if used
63 on an object with ``SUPPORTS_MULTIPLE_OBJECT_PATHS``, including any
68 * In watch_name_owner, only the desired name is watched!
70 * When cleaning up signal matches, errors are ignored. This avoids using up
71 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
72 messages if we get disconnected.
74 * Signal handlers which are bound to a unique name are automatically
75 disconnected when the unique name goes away, reducing the likelihood that
76 applications will leak signal matches.
78 * Some corrections were made to the tutorial (@service and @method take a
79 parameter dbus_interface, not just interface; fd.o #11209).
81 * ${PYTHON}-config is used to get the Python include path (patch from
82 Sebastien Bacher/Ubuntu, fd.o #11282).
84 D-Bus Python Bindings 0.81.1 (4 June 2007)
85 ==========================================
89 * When an Error message on the bus is represented as a DBusException, the
90 error name is copied into the exception and can be retrieved by
91 get_dbus_name(). Exception handlers should use this instead of looking at
92 the stringified form of the exception, unless backwards compatibility
94 * DBusException objects now get all arguments from the Error message, not
95 just the first (although there will usually only be one). Use the 'args'
96 attribute if you need to retrieve them.
97 * The Connection, BusConnection and Bus classes have a method
98 list_exported_child_objects(path: str) -> list of str, which wraps
99 dbus_connection_list_registered()
100 * You can remove objects from D-Bus before they become unreferenced, by
101 using dbus.service.Object.remove_from_connection()
102 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
106 * Don't deadlock when removing a signal match that tracks name-owner changes.
107 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
108 * Include child nodes in introspection using list_exported_child_objects()
110 D-Bus Python Bindings 0.81.0 (9 May 2007)
111 =========================================
113 The 'series of tubes' release
114 -----------------------------
116 This is a feature release with support for non-bus-daemon connections
117 and improved GObject integration.
121 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
122 but without the shared-connection semantics or any deprecated API)
123 for the benefit of those wanting to subclass bus daemon connections
125 * BusConnection has a superclass dbus.connection.Connection (a
126 connection without a bus daemon) for use in peer-to-peer situations,
127 or distributed pseudo-bus situations without a bus daemon such as
128 Telepathy's Tubes API
130 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
131 is also a subclass of GObject (with the necessary metaclass magic to
132 make this work). Until someone has verified that the GObject side of
133 things works as expected too, I consider this API to be potentially
136 * Connection and BusConnection have gained a number of useful methods,
137 including watch_name_owner (track name owner changes asynchronously,
138 avoiding race conditions), call_blocking and call_async (blocking and
139 asynchronous method calls without going via a proxy - note that these
140 are semi-low-level interfaces which don't do introspection), and
141 list_names, list_activatable_names and get_name_owner which are
142 simple wrappers for the corresponding org.freedesktop.DBus methods
144 * dbus.Interface (now also available at dbus.proxies.Interface)
145 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
149 * All keyword arguments called named_service are deprecated in favour of an
150 argument called bus_name (to be compatible with both older and newer
151 dbus-python, you should pass these positional arguments).
153 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
154 favour of an argument called conn, because proxies will work on non-bus
155 connections now (again, for maximum compatibility you should use a
156 positional argument for this).
158 * No warning is raised for this, but I consider calling any remote method
159 on a ProxyObject or Interface whose name is either alllowercase or
160 lower_case_with_underscores to be deprecated, and reserve the right
161 to add properties or methods of this form in future releases - use
162 ProxyObject.get_dbus_method if you must call a remote method named in
163 this way. Methods named following TheUsualDBusConvention or
164 theJavaConvention are safe.
168 * Exceptions in signal handlers print a stack trace to stderr (this can
169 be redirected elsewhere with Python's logging framework). Partially
170 addresses fd.o #9980.
172 * The reserved local interface and object path are properly checked for.
174 * When you return a tuple that is not a Struct from a method with no
175 out_signature, it's interpreted as multiple return values, not a
176 single Struct (closes fd.o #10174).
178 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
179 no longer crashes. This can happen when unexpectedly disconnected.
181 * Arguments are not examined for functions declared METH_NOARGS (this is
182 unnecessary and can cause a crash).
184 Other notable changes:
186 * dbus-python uses the standard Python logging framework throughout.
187 The first time a WARNING or ERROR is generated, it will configure the
188 logging framework to output to stderr, unless you have already
189 configured logging in your application.
191 * The tutorial now advocates the use of add_signal_receiver if all you
192 want to do is listen for signals: this avoids undesired activation,
193 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
