1 D-Bus Python Bindings 0.82.3 (unreleased)
2 =========================================
6 * Out-of-tree builds with an absolute $(srcdir) can now build docs and run tests
7 * Closing private dbus.Bus no longer raises KeyError (fd.o #12096)
8 * async_err_cb(MyException()) now works (fd.o #12403)
9 * dbus.service.Object.remove_from_connection no longer claims that multiple
10 exports aren't possible (fd.o #12432)
11 * Setting _dbus_error_name as a class attribute of DBusException subclasses
16 * dbus.Bus(private=True) (use dbus.bus.BusConnection in new code, dbus.Bus
17 basically just adds the shared-connection behaviour)
20 * Code for which Collabora is the only copyright holder is now under the
21 same permissive MIT/X11 license under which dbus core is being relicensed
22 (this allows everything the old license would have allowed, and more)
24 D-Bus Python Bindings 0.82.2 (2007-08-01)
25 =========================================
27 Incompatibility with 0.82.1:
29 * If you pass the timeout argument to call_async or an asynchronous proxy
30 method call and expect it to be in milliseconds, you should change the
31 argument to be in seconds, and require dbus-python >= 0.82.2.
33 This feature didn't work at all in versions prior to 0.82.1, so any code
34 that works with 0.82.0 or earlier is unaffected.
38 * @dbus.service.method supports a rel_path_keyword argument for the benefit
39 of fallback objects, which provides the method implementation with the path
40 of the object within the exported subtree. For instance, if you have a
41 fallback object exported at /Fallback, and you call a method that has
42 rel_path_keyword='rel_path' on /Fallback and on /Fallback/Some/Where, the
43 method implementation will be called with rel_path='/' and with
44 rel_path='/Some/Where' respectively. (fd.o #11623)
46 * If you have epydoc version 3 (currently in beta), API documention is now
51 * As mentioned under "Incompatibilities" above, Connection.call_async()
52 measures timeouts in seconds, as was always intended.
53 This means that calls through a proxy object with a reply_handler and
54 error_handler will measure the timeout in seconds too.
56 * Introspect() now works on objects exported in more than one location.
59 * Building against Python 2.4 on non-Debian-derived distributions, or a
60 non-default Python version on Gentoo, should work again (revenge
61 of fd.o #11282, thanks Eyal Ben David).
63 D-Bus Python Bindings 0.82.1 (2007-07-11)
64 =========================================
66 The "double precision" release.
70 * Parse the timeout correctly in send_message_with_reply() and
71 send_message_with_reply_and_block(), fixing the use of non-default timeouts
73 * The tutorial no longer uses interactive-Python syntax, as it confused users.
75 * When making a call via a proxy object with ignore_reply=True, also get the
76 necessary introspection data asynchronously. This can avoid deadlocks in
77 some cases, such as calling methods in the same process (though this is not
78 recommended, for efficiency and sanity reasons).
79 * dbus.lowlevel exposes enough constants to write correct filter functions.
80 * We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
81 is too old to have the modern replacement, dbus_watch_get_unix_fd().
85 * Omitting the bus argument in the BusName constructor is deprecated.
86 The fact that it uses the globally shared connection to the session bus by
87 default is uncomfortably subtle.
89 D-Bus Python Bindings 0.82.0 (2007-06-19)
90 =========================================
94 * dbus.service.Object can start off with no Connection or object path, and
95 become exported later. If suitable class attributes are set, objects can
96 even be exported on multiple connections, or with multiple object-paths,
99 * dbus.service.FallbackObject implements a whole subtree of object-path space
102 * ``@method`` accepts a parameter ``connection_keyword`` so methods can find
103 out which connection to use for any follow-up actions.
105 * ``@signal`` has a new parameter ``rel_path_keyword`` which gets the path at
106 which to emit the signal, relative to the path of the FallbackObject.
107 ``path_keyword`` is now deprecated, and will raise an exception if used
108 on an object with ``SUPPORTS_MULTIPLE_OBJECT_PATHS``, including any
113 * In watch_name_owner, only the desired name is watched!
115 * When cleaning up signal matches, errors are ignored. This avoids using up
116 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
117 messages if we get disconnected.
119 * Signal handlers which are bound to a unique name are automatically
120 disconnected when the unique name goes away, reducing the likelihood that
121 applications will leak signal matches.
123 * Some corrections were made to the tutorial (@service and @method take a
124 parameter dbus_interface, not just interface; fd.o #11209).
126 * ${PYTHON}-config is used to get the Python include path (patch from
127 Sebastien Bacher/Ubuntu, fd.o #11282).
129 D-Bus Python Bindings 0.81.1 (4 June 2007)
130 ==========================================
134 * When an Error message on the bus is represented as a DBusException, the
135 error name is copied into the exception and can be retrieved by
136 get_dbus_name(). Exception handlers should use this instead of looking at
137 the stringified form of the exception, unless backwards compatibility
139 * DBusException objects now get all arguments from the Error message, not
140 just the first (although there will usually only be one). Use the 'args'
141 attribute if you need to retrieve them.
142 * The Connection, BusConnection and Bus classes have a method
143 list_exported_child_objects(path: str) -> list of str, which wraps
144 dbus_connection_list_registered()
145 * You can remove objects from D-Bus before they become unreferenced, by
146 using dbus.service.Object.remove_from_connection()
147 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
151 * Don't deadlock when removing a signal match that tracks name-owner changes.
152 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
153 * Include child nodes in introspection using list_exported_child_objects()
155 D-Bus Python Bindings 0.81.0 (9 May 2007)
156 =========================================
158 The 'series of tubes' release
159 -----------------------------
161 This is a feature release with support for non-bus-daemon connections
162 and improved GObject integration.
166 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
167 but without the shared-connection semantics or any deprecated API)
168 for the benefit of those wanting to subclass bus daemon connections
170 * BusConnection has a superclass dbus.connection.Connection (a
171 connection without a bus daemon) for use in peer-to-peer situations,
172 or distributed pseudo-bus situations without a bus daemon such as
173 Telepathy's Tubes API
175 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
176 is also a subclass of GObject (with the necessary metaclass magic to
177 make this work). Until someone has verified that the GObject side of
178 things works as expected too, I consider this API to be potentially
181 * Connection and BusConnection have gained a number of useful methods,
182 including watch_name_owner (track name owner changes asynchronously,
183 avoiding race conditions), call_blocking and call_async (blocking and
184 asynchronous method calls without going via a proxy - note that these
185 are semi-low-level interfaces which don't do introspection), and
186 list_names, list_activatable_names and get_name_owner which are
187 simple wrappers for the corresponding org.freedesktop.DBus methods
189 * dbus.Interface (now also available at dbus.proxies.Interface)
190 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
194 * All keyword arguments called named_service are deprecated in favour of an
195 argument called bus_name (to be compatible with both older and newer
196 dbus-python, you should pass these positional arguments).
198 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
199 favour of an argument called conn, because proxies will work on non-bus
200 connections now (again, for maximum compatibility you should use a
201 positional argument for this).
203 * No warning is raised for this, but I consider calling any remote method
204 on a ProxyObject or Interface whose name is either alllowercase or
205 lower_case_with_underscores to be deprecated, and reserve the right
206 to add properties or methods of this form in future releases - use
207 ProxyObject.get_dbus_method if you must call a remote method named in
208 this way. Methods named following TheUsualDBusConvention or
209 theJavaConvention are safe.
213 * Exceptions in signal handlers print a stack trace to stderr (this can
214 be redirected elsewhere with Python's logging framework). Partially
215 addresses fd.o #9980.
217 * The reserved local interface and object path are properly checked for.
219 * When you return a tuple that is not a Struct from a method with no
220 out_signature, it's interpreted as multiple return values, not a
221 single Struct (closes fd.o #10174).
223 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
224 no longer crashes. This can happen when unexpectedly disconnected.
226 * Arguments are not examined for functions declared METH_NOARGS (this is
227 unnecessary and can cause a crash).
229 Other notable changes:
231 * dbus-python uses the standard Python logging framework throughout.
232 The first time a WARNING or ERROR is generated, it will configure the
233 logging framework to output to stderr, unless you have already
234 configured logging in your application.
236 * The tutorial now advocates the use of add_signal_receiver if all you
237 want to do is listen for signals: this avoids undesired activation,
238 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
