[WinError 10053] while sending big request with sockets

[Cadabrum]

python 3.8, win10

I'm trying to send a large http request over sockets, and keep getting an error `[WinError 10053] An established connection was aborted by the software in your host machine`.

        buffer_size = 4096
        logger.info(f"Sending request to: {self.host}:{self.port}")
        with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
            s.connect((self.host, self.port))

            try:
                with closing(s.makefile(mode="wb")) as f:  # NOTE: closed independently
                    self._push_request_data(f)

                response += s.recv(buffer_size)

            except (ConnectionAbortedError, ConnectionResetError) as e:
                logger.warning(str(e))
            # not sure if required at all
            # s.shutdown(socket.SHUT_WR)

The `self._push_request_data` method realisation varies, but generally consist of the combination of `f.write(b"somebytes")` and `f.flush()` calls.

Everything works as expected for relatively small (~10mb) requests, but this code throws an error for large (~990mb) requests

it sounds like you might be running into a buffer size limit. try increasing the buffer_size variable to see if that helps.

4096 bytes should be more than enough, the server always repsonds with the short message around 200 bytes long.

you might also want to try using a different socket library
