ServerSocketChannel state after disconnect() or close()

[Priyanka Perera]

Hi all,

What's the expected state of a server socket channel once the close() or disconnect() is invoked ?

Below code reports that server socket channel is still active even after the close() future is sync'ed.

final EchoServerHandler serverHandler = new EchoServerHandler();
EventLoopGroup group = new NioEventLoopGroup();
ServerBootstrap serverBootstrap = new ServerBootstrap();
serverBootstrap.group(group)
        .channel(NioServerSocketChannel.class)
        .localAddress(new InetSocketAddress(port))
        .childHandler(new ChannelInitializer<SocketChannel>(){
            @Override
            public void initChannel(SocketChannel ch)
                    throws Exception {
                ch.pipeline().addLast(serverHandler);
            }
        });

ChannelFuture channelFuture = serverBootstrap.bind().sync();
System.out.println("Server started");
Thread.sleep(5000);
Assert.assertTrue(channelFuture.channel().close().sync().isSuccess());
Assert.assertFalse(channelFuture.channel().isActive(), "Channel is active");

It fails on the last assertion with

Exception in thread "Thread-0" java.lang.AssertionError: Channel is active expected [false] but found [true]
    at org.testng.Assert.fail(Assert.java:94)
    at org.testng.Assert.failNotEquals(Assert.java:513)
    at org.testng.Assert.assertFalse(Assert.java:63)
    at EchoServer.start(EchoServer.java:43)

    at ServerStarter.run(NettyTest.java:21)
    at java.lang.Thread.run(Thread.java:748)

What's the rational behind it ?

Thanks

Priyanka
