1 D-Bus Python Bindings 0.82.2 (unreleased)
2 =========================================
4 Incompatibility with 0.82.1:
6 * If you pass the timeout argument to call_async or an asynchronous proxy
7 method call and expect it to be in milliseconds, you should change the
8 argument to be in seconds, and require dbus-python >= 0.82.2.
10 This feature didn't work at all in versions prior to 0.82.1, so any code
11 that works with 0.82.0 or earlier is unaffected.
15 * @dbus.service.method supports a rel_path_keyword argument for the benefit
16 of fallback objects, which provides the method implementation with the path
17 of the object within the exported subtree. For instance, if you have a
18 fallback object exported at /Fallback, and you call a method that has
19 rel_path_keyword='rel_path' on /Fallback and on /Fallback/Some/Where, the
20 method implementation will be called with rel_path='/' and with
21 rel_path='/Some/Where' respectively. (fd.o #11623)
25 * As mentioned under "Incompatibilities" above, Connection.call_async()
26 measures timeouts in seconds, as was always intended.
27 This means that calls through a proxy object with a reply_handler and
28 error_handler will measure the timeout in seconds too.
30 * Introspect() now works on objects exported in more than one location.
33 * Building against Python 2.4 on non-Debian-derived distributions, or a
34 non-default Python version on Gentoo, should work again (revenge
35 of fd.o #11282, thanks Eyal Ben David).
37 D-Bus Python Bindings 0.82.1 (2007-07-11)
38 =========================================
40 The "double precision" release.
44 * Parse the timeout correctly in send_message_with_reply() and
45 send_message_with_reply_and_block(), fixing the use of non-default timeouts
47 * The tutorial no longer uses interactive-Python syntax, as it confused users.
49 * When making a call via a proxy object with ignore_reply=True, also get the
50 necessary introspection data asynchronously. This can avoid deadlocks in
51 some cases, such as calling methods in the same process (though this is not
52 recommended, for efficiency and sanity reasons).
53 * dbus.lowlevel exposes enough constants to write correct filter functions.
54 * We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
55 is too old to have the modern replacement, dbus_watch_get_unix_fd().
59 * Omitting the bus argument in the BusName constructor is deprecated.
60 The fact that it uses the globally shared connection to the session bus by
61 default is uncomfortably subtle.
63 D-Bus Python Bindings 0.82.0 (2007-06-19)
64 =========================================
68 * dbus.service.Object can start off with no Connection or object path, and
69 become exported later. If suitable class attributes are set, objects can
70 even be exported on multiple connections, or with multiple object-paths,
73 * dbus.service.FallbackObject implements a whole subtree of object-path space
76 * ``@method`` accepts a parameter ``connection_keyword`` so methods can find
77 out which connection to use for any follow-up actions.
79 * ``@signal`` has a new parameter ``rel_path_keyword`` which gets the path at
80 which to emit the signal, relative to the path of the FallbackObject.
81 ``path_keyword`` is now deprecated, and will raise an exception if used
82 on an object with ``SUPPORTS_MULTIPLE_OBJECT_PATHS``, including any
87 * In watch_name_owner, only the desired name is watched!
89 * When cleaning up signal matches, errors are ignored. This avoids using up
90 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
91 messages if we get disconnected.
93 * Signal handlers which are bound to a unique name are automatically
94 disconnected when the unique name goes away, reducing the likelihood that
95 applications will leak signal matches.
97 * Some corrections were made to the tutorial (@service and @method take a
98 parameter dbus_interface, not just interface; fd.o #11209).
100 * ${PYTHON}-config is used to get the Python include path (patch from
101 Sebastien Bacher/Ubuntu, fd.o #11282).
103 D-Bus Python Bindings 0.81.1 (4 June 2007)
104 ==========================================
108 * When an Error message on the bus is represented as a DBusException, the
109 error name is copied into the exception and can be retrieved by
110 get_dbus_name(). Exception handlers should use this instead of looking at
111 the stringified form of the exception, unless backwards compatibility
113 * DBusException objects now get all arguments from the Error message, not
114 just the first (although there will usually only be one). Use the 'args'
115 attribute if you need to retrieve them.
116 * The Connection, BusConnection and Bus classes have a method
117 list_exported_child_objects(path: str) -> list of str, which wraps
118 dbus_connection_list_registered()
119 * You can remove objects from D-Bus before they become unreferenced, by
120 using dbus.service.Object.remove_from_connection()
121 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
125 * Don't deadlock when removing a signal match that tracks name-owner changes.
126 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
127 * Include child nodes in introspection using list_exported_child_objects()
129 D-Bus Python Bindings 0.81.0 (9 May 2007)
130 =========================================
132 The 'series of tubes' release
133 -----------------------------
135 This is a feature release with support for non-bus-daemon connections
136 and improved GObject integration.
140 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
141 but without the shared-connection semantics or any deprecated API)
142 for the benefit of those wanting to subclass bus daemon connections
144 * BusConnection has a superclass dbus.connection.Connection (a
145 connection without a bus daemon) for use in peer-to-peer situations,
146 or distributed pseudo-bus situations without a bus daemon such as
147 Telepathy's Tubes API
149 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
150 is also a subclass of GObject (with the necessary metaclass magic to
151 make this work). Until someone has verified that the GObject side of
152 things works as expected too, I consider this API to be potentially
155 * Connection and BusConnection have gained a number of useful methods,
156 including watch_name_owner (track name owner changes asynchronously,
157 avoiding race conditions), call_blocking and call_async (blocking and
158 asynchronous method calls without going via a proxy - note that these
159 are semi-low-level interfaces which don't do introspection), and
160 list_names, list_activatable_names and get_name_owner which are
161 simple wrappers for the corresponding org.freedesktop.DBus methods
163 * dbus.Interface (now also available at dbus.proxies.Interface)
164 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
168 * All keyword arguments called named_service are deprecated in favour of an
169 argument called bus_name (to be compatible with both older and newer
170 dbus-python, you should pass these positional arguments).
172 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
173 favour of an argument called conn, because proxies will work on non-bus
174 connections now (again, for maximum compatibility you should use a
175 positional argument for this).
177 * No warning is raised for this, but I consider calling any remote method
178 on a ProxyObject or Interface whose name is either alllowercase or
179 lower_case_with_underscores to be deprecated, and reserve the right
180 to add properties or methods of this form in future releases - use
181 ProxyObject.get_dbus_method if you must call a remote method named in
182 this way. Methods named following TheUsualDBusConvention or
183 theJavaConvention are safe.
187 * Exceptions in signal handlers print a stack trace to stderr (this can
188 be redirected elsewhere with Python's logging framework). Partially
189 addresses fd.o #9980.
191 * The reserved local interface and object path are properly checked for.
193 * When you return a tuple that is not a Struct from a method with no
194 out_signature, it's interpreted as multiple return values, not a
195 single Struct (closes fd.o #10174).
197 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
198 no longer crashes. This can happen when unexpectedly disconnected.
200 * Arguments are not examined for functions declared METH_NOARGS (this is
201 unnecessary and can cause a crash).
203 Other notable changes:
205 * dbus-python uses the standard Python logging framework throughout.
206 The first time a WARNING or ERROR is generated, it will configure the
207 logging framework to output to stderr, unless you have already
208 configured logging in your application.
210 * The tutorial now advocates the use of add_signal_receiver if all you
211 want to do is listen for signals: this avoids undesired activation,
212 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
