Race condition (LastHttpContent vs ChannelInactive)

[Ming]

Hi,

I recently got a race condition issue within netty. I am writing a client library, and in my implementation of "SimpleChannelInboundHandler", I have channelRead0() and channelInactive().

My client communicates with a server. The server will close channel if it feels something wrong, and what the server does is: 1) send 400 response to the client; 2) close the channel.

However, on the client side, there is a rare chance that channelInactive gets called before channelRead0 for the last http content. This happens rarely, only when the network is extremely good. So my question is: 1) is this expected from Netty? 2) how to ensure that channelInactive gets called after the last http content is processed?

Thanks,

Ming

Code snippet

@Override

  public void channelInactive(ChannelHandlerContext ctx) throws Exception {

    // abort request

  }

@Override

  protected void channelRead0(ChannelHandlerContext ctx, Object msg) {

    // ...

    if (msg instanceof HttpContent) {

      // ...

      if (msg instanceof LastHttpContent) {

        // complete request

      }

    }

  }

This should never happen. Please open an issue with a reproducer.
