[Libevent-users] How to handle large uploads in the evhttp based server?

[Dmitry Chichkov]

I'm writing a service using libevent 2.1.5 (beta) that needs to support
relatively large (5-10GB) PUT requests (uploads) over local 10GB ethernet.
It'd be ideal if I could handle these in a chunked mode, just like when the
client handles chunked replies, rather than consume memory or split it into
zillions of small HTTP requests...

Along these lines (server side):
   evhttp_accept_socket(http, nfd);
   evhttp_set_cb(http, "/upload", http_upload, base);

   static void http_upload(struct evhttp_request *req, void *arg) {
      if (evhttp_request_get_command(req) == EVHTTP_REQ_POST) {
          evhttp_request set_chunked_cb(req, http_upload_chunk);
      }
   }

  static void  http_upload_chunk(..)  {handle uploaded chunk of data}


I'm trying to do it, but  evhttp_request set_chunked_cb   just complains it
is in the client mode.
Is that by design?  Just not implemented?  Am I doing something wrong?


Cheers,
Dmitry
