The event loop can be broken up into a multiplexer (the part responsible for notifying us of I/O events) and the event loop proper, which wraps a multiplexer with functionality for scheduling callbacks, immediately or at a given time in the future. Whenever a public API takes a callback, subsequent positional arguments will be passed to the callback if/when it is called. This avoids the proliferation of trivial lambdas implementing closures. Keyword arguments for the callback are not supported; this is a conscious design decision, leaving the door open for keyword arguments to modify the meaning of the API call itself. � N� )� constants)� coroutines)�events)� exceptions)�futures)� protocols)�sslproto)� staggered)�tasks)� transports)�trsock)�logger)� BaseEventLoop�Server�d g �?�AF_INET6i�Q c C s, | j }tt|dd �tj�rt|j�S t| �S )N�__self__)Z _callback� isinstance�getattrr �Task�reprr �str)�handle�cb� r �:/opt/alt/python310/lib64/python3.10/asyncio/base_events.py�_format_handleJ s r c C s$ | t jkrdS | t jkrdS t| �S )Nz<pipe>z<stdout>)� subprocess�PIPE�STDOUTr )�fdr r r � _format_pipeS s r" c C sB t td�s td��z | �tjtjd� W d S ty td��w )N� SO_REUSEPORTz)reuse_port not supported by socket moduler zTreuse_port not supported by socket module, SO_REUSEPORT defined but not implemented.)�hasattr�socket� ValueError� setsockopt� SOL_SOCKETr# �OSError��sockr r r �_set_reuseport\ s �r, c C sp t td�sd S |dtjtjhvs| d u rd S |tjkr tj}n |tjkr(tj}nd S |d u r1d}n+t|t�r=|dkr=d}n t|t�rI|dkrId}nzt |�}W n t t fy[ Y d S w |tj krntj g}trm|�tj� n|g}t| t�r{| �d�} d| v r�d S |D ]2}z't�|| � tr�|tjkr�|||d| |||ffW S |||d| |ffW S ty� Y q�w d S )N� inet_ptonr � � Zidna�%)r$ r% � IPPROTO_TCPZ IPPROTO_UDP� SOCK_STREAM� SOCK_DGRAMr �bytesr �int� TypeErrorr& � AF_UNSPEC�AF_INET� _HAS_IPv6�appendr �decoder- r) ) �host�port�family�type�protoZflowinfoZscopeidZafs�afr r r � _ipaddr_infog sR � � �rB c C s� t �� }| D ]}|d }||vrg ||< || �|� qt|�� �}g }|dkr>|�|d d|d � � |d d|d �= |�dd� tj�tj |� �D �� |S )z-Interleave list of addrinfo tuples by family.r r Nc s s � | ] }|d ur|V qd S �Nr )�.0�ar r r � <genexpr>� s � ��z(_interleave_addrinfos.<locals>.<genexpr>) � collections� OrderedDictr: �list�values�extend� itertools�chain� from_iterable� zip_longest)Z addrinfosZfirst_address_family_countZaddrinfos_by_family�addrr> Zaddrinfos_listsZ reorderedr r r �_interleave_addrinfos� s" ��rQ c C s4 | � � s| �� }t|ttf�rd S t�| ��� d S rC )� cancelled� exceptionr � SystemExit�KeyboardInterruptr Z _get_loop�stop)�fut�excr r r �_run_until_complete_cb� s rY � TCP_NODELAYc C sL | j tjtjhv r | jtjkr"| jtjkr$| �tjtj d� d S d S d S d S �Nr ) r> r% r8 r r?

Return the total number of bytes which were sent. The method uses high-performance os.sendfile if available. file must be a regular file object opened in binary mode. offset tells from where to start reading the file.

File position is updated on return or also in case of error in which case file.tell() can be used to figure out the number of bytes which were sent. fallback set to True makes asyncio to manually read and send the file when the platform does not support the sendfile syscall (e.g. Windows or SSL socket on Unix).

The host parameter can be a string, in that case the TCP server is bound to host and port. The host parameter can also be a sequence of strings and in that case the TCP server is bound to all hosts of the sequence. If a host appears multiple times (possibly indirectly e.g. when hostnames resolve to the same IP address), the server is only bound once to that host. Return a Server object which can be used to stop the service.

This is called when an exception occurs and no exception handler is set, and can be called by a custom exception handler that wants to defer to the default behavior. This default handler logs the error message and other context-dependent information. In debug mode, a truncated stack trace is also appended showing where the given object (e.g. a handle or future or task) was created, if any. The context parameter has the same meaning as in `call_exception_handler()`. r z!Unhandled exception in event looprS NFZsource_tracebackZhandle_traceback> r rS r/ z+Object created at (most recent call last): z+Handle created at (most recent call last): r] � r� )�getr? � __traceback__r� r� �sortedr � traceback� format_list�rstripr r: r r� ) ri r$ r rS r� Z log_linesr� �value�tbr r r �default_exception_handler� s: �� z'BaseEventLoop.default_exception_handlerc C s� | j du r(z| �|� W dS ttfy � ty' tjddd� Y dS w z | � | |� W dS ttfy; � tyy } z3z | �d||d�� W n ttfyW � tyf tjddd� Y nw W Y d}~dS W Y d}~dS d}~ww )aD Call the current event loop's exception handler. The context argument is a dict containing the following keys: - 'message': Error message; - 'exception' (optional): Exception object; - 'future' (optional): Future instance; - 'task' (optional): Task instance; - 'handle' (optional): Handle instance; - 'protocol' (optional): Protocol instance; - 'transport' (optional): Transport instance; - 'socket' (optional): Socket instance; - 'asyncgen' (optional): Asynchronous generator that caused the exception. New keys maybe introduced in the future. Note: do not overload this method in an event loop subclass. For custom exception handling, use the `set_exception_handler()` method.
