Let's you (optionally) specify either a result value or an exception type and a callback which is returned, thrown or called respectively if a PolicyKit authorization doesn't exist or can't be obtained in the DBus mechanism, i.e. an appropriate DBus exception is thrown. An exception constructor may and a callback must accept an `action_id´ parameter which will be set to the id of the PolicyKit action for which authorization could not be obtained. Examples: 1) Return `False´ in the event of an authorization problem, and call `error_handler´: def error_handler(action_id=None): print "Authorization problem:", action_id class MyProxy(object): @polkit.enable_proxy(authfail_result=False, authfail_callback=error_handler) def some_method(self, ...): ... 2) Throw a `MyAuthError´ instance in the event of an authorization problem: class MyAuthError(Exception): def __init__(self, *args, **kwargs): action_id = kwargs.pop("action_id") super(MyAuthError, self).__init__(*args, **kwargs) self.action_id = action_id class MyProxy(object): @polkit.enable_proxy(authfail_exception=MyAuthError) def some_method(self, ...): ...c s� y | ||�S t jk r� } zr|j� }|jt�s2� |tt�d � }� d k rT� |d� �d k r�y�|d�}W n �� }Y nX |��tkr�� �S d }~X nX d S )N)� action_id)�dbus� DBusExceptionZ get_dbus_name� startswith�AUTH_EXC_PREFIX�lenr )�func�p�k�eZexc_namer Zaf_exc)�authfail_callback�authfail_exception�authfail_resultr r � _enable_proxyv s$ z#enable_proxy.<locals>._enable_proxyNc s t � | �S )N)r )r )r# r r �decorate� s z enable_proxy.<locals>.decorate)r )r r" r! r r$ r )r# r r! r" r r @ s 6 c s$ e Zd ZdZdZ� fdd�Z� ZS )r zqException which a DBus service method throws if an authorization required for executing it can't be obtained.zAorg.fedoraproject.slip.dbus.service.PolKit.NotAuthorizedExceptionc s( | j jd | | _tt| �j||� d S )N�.)� __class__�_dbus_error_name�superr �__init__)�selfr r r )r& r r r) � s z NotAuthorizedException.__init__)r r r �__doc__r' r) � __classcell__r r )r& r r � s c @ s� e Zd ZdZdZdZdZdZdZdZ dZ e dd� �Z e dd � �Ze d d � �Ze d d � �Ze dd� �Zdd� Zdd� Zdd� Zdi fdd�ZdS )�PolKitz"Convenience wrapper around polkit.zorg.freedesktop.PolicyKit1z%/org/freedesktop/PolicyKit1/Authorityz$org.freedesktop.PolicyKit1.AuthorityNc C s4 || j kr0tjr0tjjtj� d t_d t_d t_d S )N)� _dbus_namer- � _PolKit__busZremove_signal_receiver�_PolKit__signal_receiver�_PolKit__interface)�cls�nameZ old_ownerZ new_ownerr r r �_on_name_owner_changed� s z PolKit._on_name_owner_changedc C s0 t js*tj� t _t jj| jdd| jd�t _t jS )NZNameOwnerChangedzorg.freedesktop.DBus)Zhandler_functionZ signal_nameZdbus_interfaceZarg0)r- r/ r Z SystemBusZadd_signal_receiverr4 r. r0 )r* r r r �_bus� s z PolKit._busc C s t js| jj� t _t jS )N)r- �_PolKit__bus_namer5 Zget_unique_name)r* r r r � _bus_name� s zPolKit._bus_namec C sF t js@y"tj| jj| j| j�| j�t _W n tj k r> Y nX t jS )N) r- r1 r � Interfacer5 � get_objectr. � _dbus_path�_dbus_interfacer )r* r r r � _interface� s zPolKit._interfacec C s t | j�S )N)�boolr< )r* r r r �_polkit_present� s zPolKit._polkit_presentc C s> | j jdd�}tj|d�}y|j|�}W n d }Y nX |S )Nzorg.freedesktop.DBusz/org/freedesktop/DBus)r5 r9 r r8 ZGetConnectionUnixUser)r* �system_bus_nameZ bus_objectZ bus_interfaceZuidr r r Z__dbus_system_bus_name_uid� s z!PolKit.__dbus_system_bus_name_uidc C s6 | j s dS | jjdd| jif|i dd�\}}}|p4|S )NTzsystem-bus-namer3 r � )r> r< �CheckAuthorizationr7 )r* Z authorization� is_authorized� is_challenge�detailsr r r Z __authorization_is_obtainable� s z$PolKit.__authorization_is_obtainablec s8 � j s dS t|tttf�s |f}t� fdd�|d�}|S )NTc s | o � j |�S )N)�$_PolKit__authorization_is_obtainable)�x�y)r* r r �<lambda>� s z4PolKit.AreAuthorizationsObtainable.<locals>.<lambda>)r> � isinstance�tuple�list�setr )r* �authorizationsZ obtainabler )r* r r � s z"PolKit.AreAuthorizationsObtainableTc sd | j s � |d kp | j|�dk�S d}|r0|dO }� fdd�}| jjdd|if|||d||td� d S ) Nr r c s | \}}}� |� d S )Nr )�argsrB rC rD )� reply_handlerr r �reply_cb s z7PolKit.IsSystemBusNameAuthorizedAsync.<locals>.reply_cbzsystem-bus-namer3 r@ )rO � error_handlerZtimeout)r> �!_PolKit__dbus_system_bus_name_uidr< rA r ) r* r? r rO rQ � challengerD �flagsrP r )rO r r s z%PolKit.IsSystemBusNameAuthorizedAsync)r r r r+ r. r: r; r1 r/ r6 r0 � classmethodr4 �propertyr5 r7 r< r> rR rE r r r r r r r- � s" r- c C s t j| �S )N)�__polkitr )rM r r r r s Tc C s t j| |||||�S )N)rW r )r? r rO rQ rS rD r r r r s )r+ Z __future__r � collectionsr r � functoolsr Z constantsr �__all__r r �objectr r r r r- rW r r r r r r �<module> s( Wo
