小编Ily*_* O.的帖子

我正在尝试在我的应用程序中利用Server-Sent Events.我正在使用Sinatra和sinatra-sse宝石.这个宝石包裹着Sinatra的stream :keep_alive召唤.

在Thin上运行我的应用程序时,我绝对没有问题,我的事件流按预期工作.然而,当我切换我的应用程序与Puma一起运行时,一切正常,除了我sse_stream绝对没有!它只返回一个空白页面.

我的流设置如此

get "/logstream/:server" do
    if rbcserver = MyApp.servers[params[:server]]
        sse_stream do |stream|     
            rbcserver.add_web_logger(stream)
            stream.callback { rbcserver.remove_web_logger(stream) }
        end
    else
        error 404
    end
end

我这样开始瘦:

@@puma_instance = Puma::Server.new MyApp::WebUI
@@puma_instance.add_tcp_listener ip, port
@@puma_instance.run

知道发生了什么事吗？任何帮助,将不胜感激.

编辑:更多信息这是cURL在Puma上运行时提供的

$ curl -L -b cookies.txt -c cookies.txt -i http://localhost:9001/logstream/myserver    
HTTP/1.1 200 OK
Content-Type: text/event-stream;charset=utf-8
X-Content-Type-Options: nosniff
Transfer-Encoding: chunked

$

而这就是Thin上发生的事情

$ curl -L -b cookies.txt -c cookies.txt -i http://localhost:9001/logstream/myserver                                        
HTTP/1.1 200 OK
Content-Type: text/event-stream;charset=utf-8
X-Content-Type-Options: nosniff
Connection: …

所以我有一个奇怪的问题.我有一个运行linux的CI服务器的自定义rails环境设置.环境正确加载,测试在CI服务器上运行,但只有当我用bundle exec rspec而不是bundle exec rake spec或运行它们时bundle exec rake.

当测试没有运行时,它们仍然返回退出代码0,并且CI服务器假定构建成功,即使理论上构建可能被破坏.

在我的机器上运行相同的行为,运行OS X.

这是一个包含所有不同测试用例的控制台会话,以更好地说明正在发生的事情.

没有指定RAILS_ENV

所以,我正在写一个光线跟踪器,我有一个基本类来表示视口.它看起来像这样:

camera.hpp:

#define real double

class Camera
{
    // self explanatory
    Vector3 origin, destination, up;

    // camera's coordinate system
    // N    = normal to projection plane ("z-axis")
    // U, V = x- and y-axes of projection plane
    Vector3 N, U, V;

    // Directional increment vectors for screen-space X and Y
    Vector3 xInc, yInc;

    // vFOV derived from hFOV
    real    horizontalFOV, verticalFOV;

    // width and height of projection buffer in pixels
    real    width, height;
