1 D-Bus Python Bindings 0.81.1 (unreleased)
2 =========================================
6 * When an Error message on the bus is represented as a DBusException, the
7 error name is copied into the exception and can be retrieved by
8 get_dbus_name(). Exception handlers should use this instead of looking at
9 the stringified form of the exception, unless backwards compatibility
11 * DBusException objects now get all arguments from the Error message, not
12 just the first (although there will usually only be one). Use the 'args'
13 attribute if you need to retrieve them.
17 * Don't deadlock when removing a signal match that tracks name-owner changes.

20 D-Bus Python Bindings 0.81.0 (9 May 2007)
21 =========================================
23 The 'series of tubes' release
24 -----------------------------
26 This is a feature release with support for non-bus-daemon connections
27 and improved GObject integration.
31 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
32 but without the shared-connection semantics or any deprecated API)
33 for the benefit of those wanting to subclass bus daemon connections
35 * BusConnection has a superclass dbus.connection.Connection (a
36 connection without a bus daemon) for use in peer-to-peer situations,
37 or distributed pseudo-bus situations without a bus daemon such as
40 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
41 is also a subclass of GObject (with the necessary metaclass magic to
42 make this work). Until someone has verified that the GObject side of
43 things works as expected too, I consider this API to be potentially
46 * Connection and BusConnection have gained a number of useful methods,
47 including watch_name_owner (track name owner changes asynchronously,
48 avoiding race conditions), call_blocking and call_async (blocking and
49 asynchronous method calls without going via a proxy - note that these
50 are semi-low-level interfaces which don't do introspection), and
51 list_names, list_activatable_names and get_name_owner which are
52 simple wrappers for the corresponding org.freedesktop.DBus methods
54 * dbus.Interface (now also available at dbus.proxies.Interface)
55 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
59 * All keyword arguments called named_service are deprecated in favour of an
60 argument called bus_name (to be compatible with both older and newer
61 dbus-python, you should pass these positional arguments).
63 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
64 favour of an argument called conn, because proxies will work on non-bus
65 connections now (again, for maximum compatibility you should use a
66 positional argument for this).
68 * No warning is raised for this, but I consider calling any remote method
69 on a ProxyObject or Interface whose name is either alllowercase or
70 lower_case_with_underscores to be deprecated, and reserve the right
71 to add properties or methods of this form in future releases - use
72 ProxyObject.get_dbus_method if you must call a remote method named in
73 this way. Methods named following TheUsualDBusConvention or
74 theJavaConvention are safe.
78 * Exceptions in signal handlers print a stack trace to stderr (this can
79 be redirected elsewhere with Python's logging framework). Partially
82 * The reserved local interface and object path are properly checked for.
84 * When you return a tuple that is not a Struct from a method with no
85 out_signature, it's interpreted as multiple return values, not a
86 single Struct (closes fd.o #10174).
88 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
89 no longer crashes. This can happen when unexpectedly disconnected.
91 * Arguments are not examined for functions declared METH_NOARGS (this is
92 unnecessary and can cause a crash).
94 Other notable changes:
96 * dbus-python uses the standard Python logging framework throughout.
97 The first time a WARNING or ERROR is generated, it will configure the
98 logging framework to output to stderr, unless you have already
99 configured logging in your application.
101 * The tutorial now advocates the use of add_signal_receiver if all you
102 want to do is listen for signals: this avoids undesired activation,
103 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
105 D-Bus Python Bindings 0.80.2 (13 February 2007)
106 ===============================================
107 - Fix numerous memory and reference leaks
108 - Only use -Werror if the user specifically asks for it
109 - Audit tp_dealloc callbacks to make sure they correctly preserve the
111 - Relicense files solely owned by Collabora Ltd. more permissively (LGPL/AFL
112 rather than GPL/AFL) - this includes the tutorial and all the C code
114 D-Bus Python Bindings 0.80.1 (24 January 2007)
