1 D-Bus Python Bindings 0.81.2 (unreleased)
2 =========================================
6 * dbus.service.Object can start off with no Connection or object path, and
7 become exported later. If suitable class attributes are set, objects can
8 even be exported on multiple connections, or with multiple object-paths,
11 * @signal and @method accept a parameter ``connection_keyword`` so signals
12 can be emitted from a chosen connection, and methods can find out which
13 connection to use for any follow-up actions.
17 * In watch_name_owner, only the desired name is watched!
19 * When cleaning up signal matches, errors are ignored. This avoids using up
20 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
21 messages if we get disconnected.
23 * Signal handlers which are bound to a unique name are automatically
24 disconnected when the unique name goes away, reducing the likelihood that
25 applications will leak signal matches.
27 * Some corrections were made to the tutorial (@service and @method take a
28 parameter dbus_interface, not just interface; fd.o #11209).
30 D-Bus Python Bindings 0.81.1 (4 June 2007)
31 ==========================================
35 * When an Error message on the bus is represented as a DBusException, the
36 error name is copied into the exception and can be retrieved by
37 get_dbus_name(). Exception handlers should use this instead of looking at
38 the stringified form of the exception, unless backwards compatibility
40 * DBusException objects now get all arguments from the Error message, not
41 just the first (although there will usually only be one). Use the 'args'
42 attribute if you need to retrieve them.
43 * The Connection, BusConnection and Bus classes have a method
44 list_exported_child_objects(path: str) -> list of str, which wraps
45 dbus_connection_list_registered()
46 * You can remove objects from D-Bus before they become unreferenced, by
47 using dbus.service.Object.remove_from_connection()
48 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
52 * Don't deadlock when removing a signal match that tracks name-owner changes.
53 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
54 * Include child nodes in introspection using list_exported_child_objects()
56 D-Bus Python Bindings 0.81.0 (9 May 2007)
57 =========================================
59 The 'series of tubes' release
60 -----------------------------
62 This is a feature release with support for non-bus-daemon connections
63 and improved GObject integration.
67 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
68 but without the shared-connection semantics or any deprecated API)
69 for the benefit of those wanting to subclass bus daemon connections
71 * BusConnection has a superclass dbus.connection.Connection (a
72 connection without a bus daemon) for use in peer-to-peer situations,
73 or distributed pseudo-bus situations without a bus daemon such as
76 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
77 is also a subclass of GObject (with the necessary metaclass magic to
78 make this work). Until someone has verified that the GObject side of
79 things works as expected too, I consider this API to be potentially
82 * Connection and BusConnection have gained a number of useful methods,
83 including watch_name_owner (track name owner changes asynchronously,
84 avoiding race conditions), call_blocking and call_async (blocking and
85 asynchronous method calls without going via a proxy - note that these
86 are semi-low-level interfaces which don't do introspection), and
87 list_names, list_activatable_names and get_name_owner which are
88 simple wrappers for the corresponding org.freedesktop.DBus methods
90 * dbus.Interface (now also available at dbus.proxies.Interface)
91 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
95 * All keyword arguments called named_service are deprecated in favour of an
96 argument called bus_name (to be compatible with both older and newer
97 dbus-python, you should pass these positional arguments).
99 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
100 favour of an argument called conn, because proxies will work on non-bus
101 connections now (again, for maximum compatibility you should use a
102 positional argument for this).
104 * No warning is raised for this, but I consider calling any remote method
105 on a ProxyObject or Interface whose name is either alllowercase or
106 lower_case_with_underscores to be deprecated, and reserve the right
107 to add properties or methods of this form in future releases - use
108 ProxyObject.get_dbus_method if you must call a remote method named in
109 this way. Methods named following TheUsualDBusConvention or
110 theJavaConvention are safe.
114 * Exceptions in signal handlers print a stack trace to stderr (this can
115 be redirected elsewhere with Python's logging framework). Partially
116 addresses fd.o #9980.
118 * The reserved local interface and object path are properly checked for.
120 * When you return a tuple that is not a Struct from a method with no
121 out_signature, it's interpreted as multiple return values, not a
122 single Struct (closes fd.o #10174).
124 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
125 no longer crashes. This can happen when unexpectedly disconnected.
127 * Arguments are not examined for functions declared METH_NOARGS (this is
128 unnecessary and can cause a crash).
130 Other notable changes:
132 * dbus-python uses the standard Python logging framework throughout.
133 The first time a WARNING or ERROR is generated, it will configure the
134 logging framework to output to stderr, unless you have already
135 configured logging in your application.
137 * The tutorial now advocates the use of add_signal_receiver if all you
138 want to do is listen for signals: this avoids undesired activation,
139 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
