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