ZZ S)&r&a+ :mod:`threading` implementation of a WebSocket client connection. :class:`ClientConnection` provides :meth:`recv` and :meth:`send` methods for receiving and sending messages. It supports iteration to receive messages:: for message in websocket: process(message) The iterator exits normally when the connection is closed with code 1000 (OK) or 1001 (going away) or without a close code. It raises a :exc:`~websockets.exceptions.ConnectionClosedError` when the connection is closed with any other code. The ``ping_interval``, ``ping_timeout``, ``close_timeout``, and ``max_queue`` arguments have the same meaning as in :func:`connect`. Args: socket: Socket connected to a WebSocket server. protocol: Sans-I/O connection.   ping_interval ping_timeout close_timeout max_queuesocket socket.socketprotocolr r+ float | Noner,r-r.*int | None | tuple[int | None, int | None]returnNonecs*|t|_tj||||||ddS)Nr*) threadingr response_rcvdsuper__init__)selfr/r1r+r,r-r. __class__S/var/www/html/CropPilot/venv/lib/python3.10/site-packages/websockets/sync/client.pyr97s  zClientConnection.__init__Nadditional_headersHeadersLike | Noneuser_agent_header str | NonetimeoutcCs|jtd,|j|_|dur|jj||dur$|jjd||j|jWdn1s5wY|j |sDt d|jj durN|jj dS)z1 Perform the opening handshake. )expected_stateNz User-Agentz.timed out while waiting for handshake response) send_contextrr1r$requestheadersupdate setdefault send_requestr7wait TimeoutError handshake_exc)r:r?rArCr=r=r> handshakeLs   zClientConnection.handshakeeventrcs<|jdurt|ts J||_|jdSt|dS)z.

This function returns a :class:`ClientConnection` instance, which you can use to send and receive messages. :func:`connect` may be used as a context manager:: from websockets.sync.client import connect with connect(...) as websocket: ... The connection is closed automatically when exiting the context. Args: uri: URI of the WebSocket server. sock: Preexisting TCP socket. ``sock`` overrides the host and port from ``uri``. You may call :func:`socket.create_connection` to create a suitable TCP socket. ssl: Configuration for enabling TLS on the connection. server_hostname: Host name for the TLS handshake. ``server_hostname`` overrides the host name from ``uri``. origin: Value of the ``Origin`` header, for servers that require it. extensions: List of supported extensions, in order in which they should be negotiated and run. subprotocols: List of supported subprotocols, in order of decreasing preference. compression: The "permessage-deflate" extension is enabled by default. Set ``compression`` to :obj:`None` to disable it. See the :doc:`compression guide <../../topics/compression>` for details. additional_headers (HeadersLike | None): Arbitrary HTTP headers to add to the handshake request. user_agent_header: Value of the ``User-Agent`` request header. It defaults to ``"Python/x.y.z websockets/X.Y"``. Setting it to :obj:`None` removes the header. proxy: If a proxy is configured, it is used by default. Set ``proxy`` to :obj:`None` to disable the proxy or to the address of a proxy to override the system configuration. See the :doc:`proxy docs <../../topics/proxies>` for details. proxy_ssl: Configuration for enabling TLS on the proxy connection. proxy_server_hostname: Host name for the TLS handshake with the proxy. ``proxy_server_hostname`` overrides the host name from ``proxy``. open_timeout: Timeout for opening the connection in seconds. :obj:`None` disables the timeout. ping_interval: Interval between keepalive pings in seconds. :obj:`None` disables keepalive. ping_timeout: Timeout for keepalive pings in seconds. :obj:`None` disables timeouts. close_timeout: Timeout for closing the connection in seconds. :obj:`None` disables the timeout. max_size: Maximum size of incoming messages in bytes. :obj:`None` disables the limit. You may pass a ``(max_message_size, max_fragment_size)`` tuple to set different limits for messages and fragments when you expect long messages sent in short fragments. max_queue: High-water mark of the buffer where frames are received. It defaults to 16 frames. The low-water mark defaults to ``max_queue // 4``. You may pass a ``(high, low)`` tuple to set the high-water and low-water marks. If you want to disable flow control entirely, you may set it to ``None``, although that's a bad idea. logger: Logger for this client. It defaults to ``logging.getLogger("websockets.client")``. See the :doc:`logging guide <../../topics/logging>` for details. create_connection: Factory for the :class:`ClientConnection` managing the connection. Set it to a wrapper or a subclass to customize connection handling. Any other keyword arguments are passed to :func:`~socket.create_connection`. Raises: InvalidURI: If ``uri`` isn't a valid WebSocket URI. OSError: If the TCP connection fails. InvalidHandshake: If the opening handshake fails. TimeoutError: If the opening handshake times out.

This function accepts the same keyword arguments as :func:`connect`. It's only available on Unix. It's mainly useful for debugging servers listening on Unix sockets. Args: path: File system path to the Unix socket. uri: URI of the WebSocket server. ``uri`` defaults to ``ws://localhost/`` or, when a ``ssl`` is provided, to ``wss://localhost/``.
