Its positional arguments will be the arguments of the signal. By default it will receive no keyword arguments, but see the description of the optional keyword arguments below. `signal_name` : str The signal name; None (the default) matches all names `dbus_interface` : str The D-Bus interface name with which to qualify the signal; None (the default) matches all interface names `bus_name` : str A bus name for the sender, which will be resolved to a unique name if it is not already; None (the default) matches any sender. `path` : str The object path of the object which must have emitted the signal; None (the default) matches any object path :Keywords: `utf8_strings` : bool If True, the handler function will receive any string arguments as dbus.UTF8String objects (a subclass of str guaranteed to be UTF-8). If False (default) it will receive any string arguments as dbus.String objects (a subclass of unicode). `byte_arrays` : bool If True, the handler function will receive any byte-array arguments as dbus.ByteArray objects (a subclass of str). If False (default) it will receive any byte-array arguments as a dbus.Array of dbus.Byte (subclasses of: a list of ints). `sender_keyword` : str If not None (the default), the handler function will receive the unique name of the sending endpoint as a keyword argument with this name. `destination_keyword` : str If not None (the default), the handler function will receive the bus name of the destination (or None if the signal is a broadcast, as is usual) as a keyword argument with this name. `interface_keyword` : str If not None (the default), the handler function will receive the signal interface as a keyword argument with this name. `member_keyword` : str If not None (the default), the handler function will receive the signal name as a keyword argument with this name. `path_keyword` : str If not None (the default), the handler function will receive the object-path of the sending object as a keyword argument with this name. `message_keyword` : str If not None (the default), the handler function will receive the `dbus.lowlevel.SignalMessage` as a keyword argument with this name. `arg...` : unicode or UTF-8 str If there are additional keyword parameters of the form ``arg``\ *n*, match only signals where the *n*\ th argument is the value given for that keyword parameter. As of this time only string arguments can be matched (in particular, object paths and signatures can't). `named_service` : str A deprecated alias for `bus_name`. rt Nz3bus_name and named_service cannot both be specifiedr )ru zrPassing the named_service parameter to add_signal_receiver by name is deprecated: please use positional parametersrv )rw ) Z_require_main_loopr2 r3 ry ru rz r rp �acquirern � setdefaultrI �release) r7 Zhandler_function� signal_namer; rr �path�keywordsrt ru �match� by_interface� by_member�matchesr r r �add_signal_receiverI s( G z Connection.add_signal_receiverc c s� |d k rd |f}nd}|d k r(d |f}nd}|d k r>d |f}nd}x~|D ]v}| j j|�}|d krbqHxZ|D ]R}|j|d �}|d kr�qhx6|D ].}|j|d �} | d kr�q�x| D ] } | V q�W q�W qhW qHW d S )N)N)N)N)rn �get) r7 r� r; r< Z path_keysZinterface_keysZ member_keysr� r� r� �mr r r �_iter_easy_matches� s. z Connection._iter_easy_matchesc K s> |j dd �}|d k rB|d k r$td��|}ddlm} |dtdd� g } g } | jj� z�| jj|d �} | d krpd S | j|d �} | d kr�d S | j|d �} | d kr�d S x@| D ]8}||ks�|j |||||f|�r�| j |� q�| j |� q�W | r�| | |< n | |= | �s| |= | �s| j|= W d | jj � X x| D ]}| j |� �q&W d S )Nrt z3bus_name and named_service cannot both be specifiedr )ru zuPassing the named_service parameter to remove_signal_receiver by name is deprecated: please use positional parametersrv )rw ) r2 r3 ry ru rz rp r~ rn r� rR rI r� �_clean_up_signal_match)r7 Zhandler_or_matchr� r; rr r� r� rt ru �newZ deletionsr� r� r� r� r r r rb � sT z!Connection.remove_signal_receiverc C s d S )Nr )r7 r� r r r r� s z!Connection._clean_up_signal_matchc C s� t |t�stS |j� }|j� }|j� }x | j|||�D ]}|j|� q6W |tkr�|t kr�|dkr�xF| j D ]<}y || � W qh t k r� t j � tjddd� Y qhX qhW tS )zvD-Bus filter function.
