[pion-users] pion net http client not reading long binary response

[Neel B. <nee...@gm...>]

I am trying to read a application/octet-stream of content size > 200MB with
pion net synchronously. But What I get is only 1.0MB downloaded.

std::string image_stream_name =
(boost::format("/var/lib/hc/images/%1%.%2%.hc") % image_id %
instance_id).str();
pion::net::TCPConnectionPtr client_connection(new
pion::net::TCPConnection(_service));
client_connection->setLifecycle(pion::net::TCPConnection::LIFECYCLE_KEEPALIVE);
pion::net::HTTPRequest client_request;
client_request.setMethod("GET");
client_request.setResource((boost::format("/v2/images/%1%/file") %
image_id).str());
boost::system::error_code ec;
ec = client_connection->connect("localhost",
_config.glance().endpoint.port);
if(!ec){
  client_request.send(*(client_connection.get()), ec);
  if(!ec){
    pion::net::HTTPResponse client_response(client_request);
    client_response.receive(*client_connection.get(), ec);
    if(!ec){
      std::ofstream image_stream;
      image_stream.open(image_stream_name.c_str());
      std::cout << "downloading image into " << image_stream_name <<
std::endl;
      std::cout << "image size: " << client_response.getContentLength() <<
" chunked: " << client_response.isChunked() << std::endl;

      client_response.write(image_stream, ec);
    }
  }
}

This same works if response size is smaller. However it is not working for
larger responses.

returned response content length is wrong. in chrome I see
Content-Length:228599296

image size: 1048576 chunked: 0
