Example 16 with FutureCallback

use of org.eclipse.jetty.util.FutureCallback in project jetty.project by eclipse.

the class ByteArrayEndPointTest method testReadable.

@Test

Example 17 with FutureCallback

use of org.eclipse.jetty.util.FutureCallback in project jetty.project by eclipse.

the class ByteArrayEndPointTest method testIdle.

@Slow
@Test

    assertTrue(endp.isOpen());
    Thread.sleep(oneAndHalfIdleTimeout);
    // Still open because it has not been oshut or closed explicitly
    // and there are no callbacks, so idle timeout is ignored.
    assertTrue(endp.isOpen());
    // Normal read is immediate, since there is data to read.
    ByteBuffer buffer = BufferUtil.allocate(1024);
    FutureCallback fcb = new FutureCallback();

    assertThat("Endpoint open", endp.isOpen(), is(true));
    // We need to delay the write timeout test below from the read timeout test above.
    // The reason is that the scheduler thread that fails the endPoint WriteFlusher
    // because of the read timeout above runs concurrently with the write below, and
    // if it runs just after the write below, the test fails because the write callback
    // below fails immediately rather than after the idle timeout.
    Thread.sleep(halfIdleTimeout);
    // Write more than the output capacity, then wait for idle timeout.

    // Make sure the endPoint is closed when the callback fails.
    endp.fillInterested(new Closer(endp));
    Thread.sleep(halfIdleTimeout);
