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 * Introspect() now works on objects exported in more than one location.
17 * Building against Python 2.4 on non-Debian-derived distributions, or a
18 non-default Python version on Gentoo, should work again (revenge
19 of fd.o #11282, thanks Eyal Ben David).
21 D-Bus Python Bindings 0.82.1 (2007-07-11)
22 =========================================
24 The "double precision" release.
28 * Parse the timeout correctly in send_message_with_reply() and
29 send_message_with_reply_and_block(), fixing the use of non-default timeouts
31 * The tutorial no longer uses interactive-Python syntax, as it confused users.
33 * When making a call via a proxy object with ignore_reply=True, also get the
34 necessary introspection data asynchronously. This can avoid deadlocks in
35 some cases, such as calling methods in the same process (though this is not
36 recommended, for efficiency and sanity reasons).
37 * dbus.lowlevel exposes enough constants to write correct filter functions.
38 * We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
39 is too old to have the modern replacement, dbus_watch_get_unix_fd().
43 * Omitting the bus argument in the BusName constructor is deprecated.
44 The fact that it uses the globally shared connection to the session bus by
45 default is uncomfortably subtle.
47 D-Bus Python Bindings 0.82.0 (2007-06-19)
48 =========================================
52 * dbus.service.Object can start off with no Connection or object path, and
53 become exported later. If suitable class attributes are set, objects can
54 even be exported on multiple connections, or with multiple object-paths,
57 * dbus.service.FallbackObject implements a whole subtree of object-path space
60 * ``@method`` accepts a parameter ``connection_keyword`` so methods can find
61 out which connection to use for any follow-up actions.
63 * ``@signal`` has a new parameter ``rel_path_keyword`` which gets the path at
64 which to emit the signal, relative to the path of the FallbackObject.
65 ``path_keyword`` is now deprecated, and will raise an exception if used
66 on an object with ``SUPPORTS_MULTIPLE_OBJECT_PATHS``, including any
71 * In watch_name_owner, only the desired name is watched!
73 * When cleaning up signal matches, errors are ignored. This avoids using up
74 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
75 messages if we get disconnected.
77 * Signal handlers which are bound to a unique name are automatically
78 disconnected when the unique name goes away, reducing the likelihood that
79 applications will leak signal matches.
81 * Some corrections were made to the tutorial (@service and @method take a
82 parameter dbus_interface, not just interface; fd.o #11209).
84 * ${PYTHON}-config is used to get the Python include path (patch from
85 Sebastien Bacher/Ubuntu, fd.o #11282).
87 D-Bus Python Bindings 0.81.1 (4 June 2007)
88 ==========================================
92 * When an Error message on the bus is represented as a DBusException, the
93 error name is copied into the exception and can be retrieved by
94 get_dbus_name(). Exception handlers should use this instead of looking at
95 the stringified form of the exception, unless backwards compatibility
97 * DBusException objects now get all arguments from the Error message, not
98 just the first (although there will usually only be one). Use the 'args'
99 attribute if you need to retrieve them.
100 * The Connection, BusConnection and Bus classes have a method
101 list_exported_child_objects(path: str) -> list of str, which wraps
102 dbus_connection_list_registered()
103 * You can remove objects from D-Bus before they become unreferenced, by
104 using dbus.service.Object.remove_from_connection()
105 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
109 * Don't deadlock when removing a signal match that tracks name-owner changes.
110 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
111 * Include child nodes in introspection using list_exported_child_objects()
113 D-Bus Python Bindings 0.81.0 (9 May 2007)
114 =========================================
116 The 'series of tubes' release
117 -----------------------------
119 This is a feature release with support for non-bus-daemon connections
120 and improved GObject integration.
124 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
125 but without the shared-connection semantics or any deprecated API)
126 for the benefit of those wanting to subclass bus daemon connections
128 * BusConnection has a superclass dbus.connection.Connection (a
129 connection without a bus daemon) for use in peer-to-peer situations,
130 or distributed pseudo-bus situations without a bus daemon such as
131 Telepathy's Tubes API
133 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
134 is also a subclass of GObject (with the necessary metaclass magic to
135 make this work). Until someone has verified that the GObject side of
136 things works as expected too, I consider this API to be potentially
139 * Connection and BusConnection have gained a number of useful methods,
140 including watch_name_owner (track name owner changes asynchronously,
141 avoiding race conditions), call_blocking and call_async (blocking and
142 asynchronous method calls without going via a proxy - note that these
143 are semi-low-level interfaces which don't do introspection), and
144 list_names, list_activatable_names and get_name_owner which are
145 simple wrappers for the corresponding org.freedesktop.DBus methods
147 * dbus.Interface (now also available at dbus.proxies.Interface)
148 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
152 * All keyword arguments called named_service are deprecated in favour of an
153 argument called bus_name (to be compatible with both older and newer
154 dbus-python, you should pass these positional arguments).
156 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
157 favour of an argument called conn, because proxies will work on non-bus
158 connections now (again, for maximum compatibility you should use a
159 positional argument for this).
161 * No warning is raised for this, but I consider calling any remote method
162 on a ProxyObject or Interface whose name is either alllowercase or
163 lower_case_with_underscores to be deprecated, and reserve the right
164 to add properties or methods of this form in future releases - use
165 ProxyObject.get_dbus_method if you must call a remote method named in
166 this way. Methods named following TheUsualDBusConvention or
167 theJavaConvention are safe.
171 * Exceptions in signal handlers print a stack trace to stderr (this can
172 be redirected elsewhere with Python's logging framework). Partially
173 addresses fd.o #9980.
175 * The reserved local interface and object path are properly checked for.
177 * When you return a tuple that is not a Struct from a method with no
178 out_signature, it's interpreted as multiple return values, not a
179 single Struct (closes fd.o #10174).
181 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
182 no longer crashes. This can happen when unexpectedly disconnected.
184 * Arguments are not examined for functions declared METH_NOARGS (this is
185 unnecessary and can cause a crash).
187 Other notable changes:
189 * dbus-python uses the standard Python logging framework throughout.
190 The first time a WARNING or ERROR is generated, it will configure the
191 logging framework to output to stderr, unless you have already
192 configured logging in your application.
194 * The tutorial now advocates the use of add_signal_receiver if all you
195 want to do is listen for signals: this avoids undesired activation,
196 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
