----------------------------------

             Summary: Libprocess endpoints can ignore required gzip compression
                 Key: MESOS-9451
                 URL: https://issues.apache.org/jira/browse/MESOS-9451
             Project: Mesos
          Issue Type: Bug
            Reporter: Benno Evers


Currently, libprocess decides whether a response should be compressed by the 
following conditional:
{noformat}
    if (response.type == http::Response::BODY &&
        response.body.length() >= GZIP_MINIMUM_BODY_LENGTH &&
        !headers.contains("Content-Encoding") &&
        request.acceptsEncoding("gzip")) {
      [...]
{noformat}

However, this implies that a request sent with the header "Accept-Encoding: 
gzip" can not rely on actually getting a gzipped response, e.g. when the 
response size is below the threshold:
{noformat}
$ nc localhost 5050
GET /tasks HTTP/1.1
Accept-Encoding: gzip

HTTP/1.1 200 OK
Date: Tue, 04 Dec 2018 12:49:56 GMT
Content-Type: application/json
Content-Length: 12

{"tasks":[]}
{noformat}
