改造问题记录： * 高并发时偶现`headers not received before payload` 构造`StreamChannel`时调用了直接`syncUninterruptibly`取出channel，然后再`addLast`会导致高并发时偶现`headers not received before payload`。其本质原因是`addLast`会判断是否为`eventloop`线程组，如果不是则会提交任务到`eventloop`中，那么持续高并发的情况下就有可能出现：`请求发送成功并且收到了响应，但pipeline实际上并未组装完成，导致header丢失，从而报错 headers not received before payload`。具体源码参见`io.netty.channel.AbstractChannelHandlerContext#invokeHandler` ````java Http2StreamChannel channel = bootstrap.open().syncUninterruptibly().getNow(); channel.pipeline().addLast(new TripleHttp2ClientResponseHandler(createTransportListener())); channel.closeFuture().addListener(f -> transportException(f.cause())); ```` -- This is an automated message from the Apache Git Service.
