Re: [jetty-users] Does Jetty call Thread.interrupt?

Thread.interrupt() is called in many places in code.  

  jetty-ant
    org.eclipse.jetty.ant
      AntBuild
        stop()
          _process.interrupt();
  jetty-server
    org.eclipse.jetty.server
      AbstractConnector
        interruptAcceptors()
          thread.interrupt();
      AsyncRequestLogWriter
        doStop()
          _thread.interrupt();
      ResponseWriter
        write(int)
          Thread.currentThread().interrupt();
        write(char[], int, int)
          Thread.currentThread().interrupt();
        write(String, int, int)
          Thread.currentThread().interrupt();
        println()
          Thread.currentThread().interrupt();
        println(char)
          Thread.currentThread().interrupt();
        println(char[])
          Thread.currentThread().interrupt();
        println(String)
          Thread.currentThread().interrupt();
        format(Locale, String, Object...)
          Thread.currentThread().interrupt();
  jetty-servlets
    org.eclipse.jetty.servlets
      DoSFilter
        onRequestTimeout(HttpServletRequest, HttpServletResponse, Thread)
          handlingThread.interrupt();
  jetty-util
    org.eclipse.jetty.util
      LeakDetector
        doStop()
          thread.interrupt();
      SocketAddressResolver.Async
        resolve(String, int, Promise<List<InetSocketAddress>>)
          thread.interrupt();
    org.eclipse.jetty.util.component
      Graceful
        shutdown(ThrowingRunnable)
          thread.interrupt();
    org.eclipse.jetty.util.thread
      QueuedThreadPool
        doStop()
          thread.interrupt();
        interruptThread(long)
          thread.interrupt();
      ReservedThreadExecutor
        doStop()
          .forEach(Thread::interrupt);



What are you trying to do? or are concerned about?
Know that there's no expectation that 1 request/response exchange is handled by 1 thread in Jetty.
It can be 1..n threads over its lifetime (depends on the technology used during that request/response exchange)
Gets even more complex with your choice of protocols in use too. (websocket vs http/1.1)

Hi all,

Are there scenarios in which Jetty might call Thread.interrupt on
application code?

Cheers,
