D-Bus Python Bindings 1.1.0 (2012-05-09)
The “eaten by spiders” release.
Deprecations:
- dbus.gobject_service is deprecated. Use dbus.gi_service and PyGI in new code.
API changes:
- dbus.gobject_service works in legacy PyGObject 2 applications again,
like it did before 1.0. The down side is that it doesn't work in all PyGI
applications any more, unlike 1.0. In PyGI applications, depend on
dbus-python >= 1.1 and use dbus.gi_service instead - its API is the same.
(fd.o #48904, Debian #670516)
- dbus.gobject_service has been removed from Python 3 builds altogether.
Enhancements:
- Use DBusBasicValue from libdbus 1.5, if available, rather than reinventing it
Fixes:
- Put sockets for the regression tests in /tmp, not the builddir, fixing
test failures in a really long builddir (fd.o #46747)
- Fix a reference leak in dbus_py_variant_level_set (fd.o #47108)
- Modify AM_CHECK_PYTHON_HEADERS so the "another way" works with Python 3
D-Bus Python Bindings 1.0.0 (2012-01-24)
The "never trust a .0 release?" release.
Dependencies:
- libdbus 1.4 or later is now required.
- Python 2.6 or later is now required. If Python 3 is used, it must be
version 3.2 or later.
- GNU make (or, at your own risk, another make with the GNU $(patsubst)
extension) is now required.
API changes:
- dbus_bindings, which was never meant to be public API and has been
deprecated for nearly 5 years, has finally been removed.
- The repr() of every dbus-python object is now unicode.
- The Python 3 API is not the same as the Python 2 API; see PY3PORT.rst
for details.
- dbus.gobject_service uses PyGI, not PyGObject. (This was not meant to be
an incompatible change, but unfortunately, it was. It was reverted in 1.1.0.)
Enhancements:
- Python 3 compatibility (fd.o #26420, Barry Warsaw)
- MethodCallMessage and SignalMessage now have a more useful repr()
(Barry Warsaw)
Fixes:
- OOM while appending a unicode object to a message no longer leaks a string
(Barry Warsaw)
- If libdbus somehow gives us invalid UTF-8, don't crash (Barry Warsaw)
- Fix rst2html failure in non-UTF-8 locales (Alexandre Rostovtsev)
D-Bus Python Bindings 0.84.0 (2011-05-25)
The "Comrade Bill Bartram's Egalitarian Anti-Imperialist Soviet Stout" release.
Enhancements:
- fd.o #30812: add the UnixFd type, and support Unix fd passing if
compiled against a new enough libdbus (Elvis Pfützenreuter)
- fd.o #34342: add Connection.set_allow_anonymous(bool) (Scott Tsai)
- fd.o #21017: add configure arguments PYTHON_INCLUDES and PYTHON_LIBS which
can be used to override $PYTHON-config (Simon McVittie, based on a patch from
Robert Schwebel)
Fixes:
- fd.o #35626: clear ProxyObject's pending introspection queue after
execution (Scott Tsai)
- fd.o #22560: remove duplicate code from example-async-client (Simon McVittie)
- fd.o #36206: allow signature='x' among ProxyObject method arguments
(Simon McVittie)
D-Bus Python Bindings 0.83.2 (2010-12-02)
Dependencies:
- libdbus 1.2 is still supported, but libdbus >= 1.4 is recommended.
Fixes:
- Make BusConnection.list_activatable_names actually call ListActivatableNames,
not ListNames (Johan Sandelin)
- Don't override CFLAGS when adding compiler warnings
(Louis-Francis Ratté-Boulianne)
- Fix compilation on platforms where Py_ssize_t is larger than int, like x86-64
(Elvis Pfützenreuter)
- fd.o #21831: deserialize empty byte arrays with byte_arrays=True as
ByteArray(''), not ByteArray('None') (Simon McVittie)
- fd.o #23278, #25105: fix crashes when trying to append more struct entries
than the signature allows with libdbus 1.4 (Simon McVittie)
- fd.o #23831: fix crashes when an embedded Python interpreter imports dbus,
is finalized, is re-initialized, and re-imports dbus (Simon McVittie)
D-Bus Python Bindings 0.83.1 (2010-02-18)
Fixes:
- fd.o #21172: avoid some deprecation warnings in Python 2.6
- fd.o #15013: add dbus.lowlevel.MESSAGE_TYPE_SIGNAL etc., for those who care
about message types at a low level
- When removing signal matches, clean up internal state, avoiding a memory
leak in long-lived Python processes that connect to signals from arbitrarily
many object paths (fd.o #17551, thanks to Marco Pesenti Gritti)
- When setting the sender of a message, allow it to be org.freedesktop.DBus
so you can implement a D-Bus daemon in pure Python (patch from Huang Peng)
D-Bus Python Bindings 0.83.0 (2008-07-23)
Features:
- Add bindings for DBusServer (thanks to Mathias Hasselmann, Huang Peng;
fd.o #14322, #15514).
- Omit the service's traceback from certain D-Bus errors: specifically, those
that were probably deliberately raised as part of an API. Subclasses
of DBusException that indicate programmer error can turn the traceback
back on if it seems likely to be useful.
Fixes:
- Don't emit spurious Error messages if libdbus gives object-path handlers
a message that isn't a method call (most likely because of binding to a
locally emitted signal, as in fd.o #14199).
- Make multiple filters added by Connection.add_message_filter work
(fd.o #15547, thanks to Huang Peng).
- Make the API docs build correctly when out-of-tree
- Require dbus 1.0 so we can get rid of DBUS_API_SUBJECT_TO_CHANGE
D-Bus Python Bindings 0.82.4 (2007-12-10)
Fixes:
- supplying reply_handler but not error_handler raises
MissingReplyHandlerException instead of MissingErrorHandlerException,
and vice versa (fd.o #12304, patch from René Neumann)
- Using non-recursive make for dbus/ directory should fix builds in some
environments (fd.o #12741)
Licensing:
- Everything is now under the same MIT/X11 license used for Collabora code in
the previous release
- Added copyright headers to some files that were still missing them
D-Bus Python Bindings 0.82.3 (2007-09-27)
Fixes:
- Out-of-tree builds with an absolute $(srcdir) can now build docs and run tests
- Closing private dbus.Bus no longer raises KeyError (fd.o #12096)
- async_err_cb(MyException()) now works (fd.o #12403)
- dbus.service.Object.remove_from_connection no longer claims that multiple
exports aren't possible (fd.o #12432)
- Setting _dbus_error_name as a class attribute of DBusException subclasses
works again
Deprecations:
- dbus.Bus(private=True) (use dbus.bus.BusConnection in new code, dbus.Bus
basically just adds the shared-connection behaviour)
Licensing:
- Code for which Collabora is the only copyright holder is now under the
same permissive MIT/X11 license under which dbus core is being relicensed
(this allows everything the old license would have allowed, and more)
D-Bus Python Bindings 0.82.2 (2007-08-01)
Incompatibility with 0.82.1:
If you pass the timeout argument to call_async or an asynchronous proxy
method call and expect it to be in milliseconds, you should change the
argument to be in seconds, and require dbus-python >= 0.82.2.
This feature didn't work at all in versions prior to 0.82.1, so any code
that works with 0.82.0 or earlier is unaffected.
Features:
- @dbus.service.method supports a rel_path_keyword argument for the benefit
of fallback objects, which provides the method implementation with the path
of the object within the exported subtree. For instance, if you have a
fallback object exported at /Fallback, and you call a method that has
rel_path_keyword='rel_path' on /Fallback and on /Fallback/Some/Where, the
method implementation will be called with rel_path='/' and with
rel_path='/Some/Where' respectively. (fd.o #11623)
- If you have epydoc version 3 (currently in beta), API documention is now
generated by default.
Fixes:
- As mentioned under "Incompatibilities" above, Connection.call_async()
measures timeouts in seconds, as was always intended.
This means that calls through a proxy object with a reply_handler and
error_handler will measure the timeout in seconds too.
- Introspect() now works on objects exported in more than one location.
(fd.o #11794)
- Building against Python 2.4 on non-Debian-derived distributions, or a
non-default Python version on Gentoo, should work again (revenge
of fd.o #11282, thanks Eyal Ben David).
D-Bus Python Bindings 0.82.1 (2007-07-11)
The "double precision" release.
Fixes:
- Parse the timeout correctly in send_message_with_reply() and
send_message_with_reply_and_block(), fixing the use of non-default timeouts
(bugs.fd.o #11489)
- The tutorial no longer uses interactive-Python syntax, as it confused users.
(bugs.fd.o #11209)
- When making a call via a proxy object with ignore_reply=True, also get the
necessary introspection data asynchronously. This can avoid deadlocks in
some cases, such as calling methods in the same process (though this is not
recommended, for efficiency and sanity reasons).
- dbus.lowlevel exposes enough constants to write correct filter functions.
- We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
is too old to have the modern replacement, dbus_watch_get_unix_fd().
Deprecations:
- Omitting the bus argument in the BusName constructor is deprecated.
The fact that it uses the globally shared connection to the session bus by
default is uncomfortably subtle.
D-Bus Python Bindings 0.82.0 (2007-06-19)
Features:
- dbus.service.Object can start off with no Connection or object path, and
become exported later. If suitable class attributes are set, objects can
even be exported on multiple connections, or with multiple object-paths,
or both.
- dbus.service.FallbackObject implements a whole subtree of object-path space
(fd.o #9295).
- @method accepts a parameter connection_keyword so methods can find
out which connection to use for any follow-up actions.
- @signal has a new parameter rel_path_keyword which gets the path at
which to emit the signal, relative to the path of the FallbackObject.
path_keyword is now deprecated, and will raise an exception if used
on an object with SUPPORTS_MULTIPLE_OBJECT_PATHS, including any
FallbackObject.
Fixes:
- In watch_name_owner, only the desired name is watched!
- When cleaning up signal matches, errors are ignored. This avoids using up
scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
messages if we get disconnected.
- Signal handlers which are bound to a unique name are automatically
disconnected when the unique name goes away, reducing the likelihood that
applications will leak signal matches.
- Some corrections were made to the tutorial (@service and @method take a
parameter dbus_interface, not just interface; fd.o #11209).
- ${PYTHON}-config is used to get the Python include path (patch from
Sebastien Bacher/Ubuntu, fd.o #11282).
D-Bus Python Bindings 0.81.1 (4 June 2007)
Features:
- When an Error message on the bus is represented as a DBusException, the
error name is copied into the exception and can be retrieved by
get_dbus_name(). Exception handlers should use this instead of looking at
the stringified form of the exception, unless backwards compatibility
is needed.
- DBusException objects now get all arguments from the Error message, not
just the first (although there will usually only be one). Use the 'args'
attribute if you need to retrieve them.
- The Connection, BusConnection and Bus classes have a method
list_exported_child_objects(path: str) -> list of str, which wraps
dbus_connection_list_registered()
- You can remove objects from D-Bus before they become unreferenced, by
using dbus.service.Object.remove_from_connection()
(https://bugs.freedesktop.org/show_bug.cgi?id=10457)
Bug fixes:
D-Bus Python Bindings 0.81.0 (9 May 2007)
The 'series of tubes' release
This is a feature release with support for non-bus-daemon connections
and improved GObject integration.
Features:
- Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
but without the shared-connection semantics or any deprecated API)
for the benefit of those wanting to subclass bus daemon connections
- BusConnection has a superclass dbus.connection.Connection (a
connection without a bus daemon) for use in peer-to-peer situations,
or distributed pseudo-bus situations without a bus daemon such as
Telepathy's Tubes API
- dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
is also a subclass of GObject (with the necessary metaclass magic to
make this work). Until someone has verified that the GObject side of
things works as expected too, I consider this API to be potentially
subject to change!
- Connection and BusConnection have gained a number of useful methods,
including watch_name_owner (track name owner changes asynchronously,
avoiding race conditions), call_blocking and call_async (blocking and
asynchronous method calls without going via a proxy - note that these
are semi-low-level interfaces which don't do introspection), and
list_names, list_activatable_names and get_name_owner which are
simple wrappers for the corresponding org.freedesktop.DBus methods
- dbus.Interface (now also available at dbus.proxies.Interface)
and dbus.proxies.ProxyObject now have some reasonably obvious properties.
Deprecations:
- All keyword arguments called named_service are deprecated in favour of an
argument called bus_name (to be compatible with both older and newer
dbus-python, you should pass these positional arguments).
- The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
favour of an argument called conn, because proxies will work on non-bus
connections now (again, for maximum compatibility you should use a
positional argument for this).
- No warning is raised for this, but I consider calling any remote method
on a ProxyObject or Interface whose name is either alllowercase or
lower_case_with_underscores to be deprecated, and reserve the right
to add properties or methods of this form in future releases - use
ProxyObject.get_dbus_method if you must call a remote method named in
this way. Methods named following TheUsualDBusConvention or
theJavaConvention are safe.
Bugfixes:
- Exceptions in signal handlers print a stack trace to stderr (this can
be redirected elsewhere with Python's logging framework). Partially
addresses fd.o #9980.
- The reserved local interface and object path are properly checked for.
- When you return a tuple that is not a Struct from a method with no
out_signature, it's interpreted as multiple return values, not a
single Struct (closes fd.o #10174).
- If send_with_reply() returns TRUE but with pending call NULL, dbus-python
no longer crashes. This can happen when unexpectedly disconnected.
- Arguments are not examined for functions declared METH_NOARGS (this is
unnecessary and can cause a crash).
Other notable changes:
- dbus-python uses the standard Python logging framework throughout.
The first time a WARNING or ERROR is generated, it will configure the
logging framework to output to stderr, unless you have already
configured logging in your application.
- The tutorial now advocates the use of add_signal_receiver if all you
want to do is listen for signals: this avoids undesired activation,
e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
