Functions by replacing the named function at the instance __dict__ level, effectively providing an override for exactly one instance of `method`'s object. Queues the invocations. Run them later with .run(), which also reverses the redirection by deleting the named methods from the instance. c C s* t �� | _|| _| jD ]}| �|� qd S �N)� collections�deque�queue�methods�_wrap)�selfr �method� r �2/usr/lib/python3.9/site-packages/cockpit/router.py�__init__& s zExecutionQueue.__init__c s t � j� jj� �fdd�� d S )Nc s �j �� | f�S r )r �append)�args�r r r r �<lambda>1 � z&ExecutionQueue._wrap.<locals>.<lambda>)�setattr�__self__�__func__�__name__)r r r r r r - s zExecutionQueue._wrapN��returnc C sJ t �dt| j�� | jD ]\}}||� q| jD ]}t|j|jj� q0d S )Nz.ExecutionQueue: Running %d queued method calls) �logger�debug�lenr r �delattrr r r )r r r r r r �run3 s zExecutionQueue.run)r � __module__� __qualname__�__doc__r r r& r r r r r s r c @ s� e Zd ZU ded< dZee ed< dd�dd�Zdd�d d �Zdd�d d �Z dd�d d�Z e e e dd�dd�Z e edd�dd�Zdde dd�dd�Ze edd�dd�Ze e dedd �d d �Zd"dedd �d d!�ZdS )#�Endpoint�Router�routerN� _Endpoint__endpoint_frozen_queue�r, c C s |� | � || _d S r )� add_endpointr, �r r, r r r r @ s zEndpoint.__init__r c C s4 | j d u sJ �t�d| � t| j| j| jh�| _ d S )NzFreezing endpoint %s)r- r" r# r �do_channel_control�do_channel_data�do_kill�r r r r �freeze_endpointD s zEndpoint.freeze_endpointc C s. | j d usJ �t�d| � | j �� d | _ d S )NzThawing endpoint %s)r- r" r# r& r4 r r r � thaw_endpointI s zEndpoint.thaw_endpointc C s t �d S r ��NotImplementedErrorr4 r r r �do_closeP s zEndpoint.do_close��channel�command�messager! c C s t �d S r r7 )r r; r< r= r r r r1 S s zEndpoint.do_channel_control�r; �datar! c C s t �d S r r7 �r r; r? r r r r2 V s zEndpoint.do_channel_data� str | None��host�groupr= r! c C s t �d S r r7 )r rC rD r= r r r r3 Y s zEndpoint.do_killc C s | j �||� d S r )r, Zwrite_channel_datar@ r r r �send_channel_data] s zEndpoint.send_channel_data�JsonObject | None)r; r< �msg�kwargsr! c K sD | j j|f||d�|�� |dkr@| j j| �|� | j �|� d S )N)r; r< �close)r, � write_control� endpoints�remove� drop_channel)r r; r< rG rH r r r �send_channel_control` s z Endpoint.send_channel_control)rG rH r! c K s | j j| |fi |�� d S r )r, �shutdown_endpoint)r rG rH r r r rO h s zEndpoint.shutdown_endpoint)N)r r' r( �__annotations__r- r r r r5 r6 r9 �strr r1 �bytesr2 r3 rE r rN rO r r r r r* < s � r* c @ s e Zd ZdS )� RoutingErrorN)r r' r( r r r r rS l s rS c @ sF e Zd ZU ded< dd�dd�Zeee d�dd�Zd d �d d �Z d S ) � RoutingRuler+ r, r. c C s || _ d S r r. r0 r r r r s s zRoutingRule.__init__��optionsr! c C s t �dS )a] Check if a routing rule applies to a given 'open' message.
