This does not actually do any processing on the data, just stores it. To trigger processing, you have to call :meth:`next_event`. Args: data (:term:`bytes-like object`): The new data that was just received. Special case: If *data* is an empty byte-string like ``b""``, then this indicates that the remote side has closed the connection (end of file). Normally this is convenient, because standard Python APIs like :meth:`file.read` or :meth:`socket.recv` use ``b""`` to indicate end-of-file, while other failures to read are indicated using other mechanisms like raising :exc:`TimeoutError`. When using such an API you can just blindly pass through whatever you get from ``read`` to :meth:`receive_data`, and everything will work. But, if you have an API where reading an empty string is a valid non-EOF condition, then you need to be aware of this and make sure to check for such strings and avoid passing them to :meth:`receive_data`. Returns: Nothing, but after calling this you should call :meth:`next_event` to parse the newly received data. Raises: RuntimeError: Raised if you pass an empty *data*, indicating EOF, and then pass a non-empty *data*, indicating more data that somehow arrived after the EOF. (Calling ``receive_data(b"")`` multiple times is fine, and equivalent to calling it once.) z(received close, then received more data?TN)r[ RuntimeErrorrZ)r_rr0r0r1 receive_data`s ' zConnection.receive_datacCs|j}|tur |jr tS|tus|turtS|jdusJ||j}|dur<|js<|jr` to send. Returns: If ``type(event) is ConnectionClosed``, then returns ``None``. Otherwise, returns a :term:`bytes-like object`. Raises: LocalProtocolError: Sending this event at this time would violate our understanding of the HTTP/1.1 protocol. If this method raises any exception then it also sets :attr:`Connection.our_state` to :data:`ERROR` -- see :ref:`error-handling` for discussion.
