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)rg RuntimeErrorrf)rkrs r6 receive_dataConnection.receive_data`s6N **"#MNN  D ( *.D 'r5cURnU[LaUR(a[$U[Ld U[ La[$UR ceUR UR5nUcbUR(dQUR(a@[UR S5(aUR R5nO [5nUc[nU$)Nread_eof) rwrrfr+r r#rerghasattrrr r*)rkrr;s r6_extract_next_receive_event&Connection._extract_next_receive_events   D=T11M ) )U6G-GM||''' T112 =''D,G,G 4<<44 LL113E,.E =E r5c,UR[La [S5eUR5nU[[ 4;a*UR UR[[U55 U[LaI[UR5UR:a [SSS9eUR(a [S5eU$![aKnURUR5 [!U["5(aUR%5 SnAgeSnAff=f)anParse the next event out of our receive buffer, update our internal state, and return it. This is a mutating operation -- think of it like calling :func:`next` on an iterator. Returns: : One of three things: 1) An event object -- see :ref:`events`. 2) The special constant :data:`NEED_DATA`, which indicates that you need to read more data from your socket and pass it to :meth:`receive_data` before this method will be able to return any more events. 3) The special constant :data:`PAUSED`, which indicates that we are not in a state where we can process incoming data (usually because the peer has finished their part of the current request/response cycle, and you have not yet called :meth:`start_next_cycle`). See :ref:`flow-control` for details. Raises: RemoteProtocolError: The peer has misbehaved. You should close the connection (possibly after sending some kind of 4xx response). Once this method returns :class:`ConnectionClosed` once, then all subsequent calls will also return :class:`ConnectionClosed`. If this method raises any exception besides :exc:`RemoteProtocolError` then that's a bug -- if it happens please file a bug report!
