Wow, almost a complete re-write! Nice job. |
|
Yes, Netty 4 is very different to Netty 3 - but also implementing back pressure rather than buffer limits meant it changed significantly. |
|
Yep, I've heard that backpressure is a good thing. ;-) |

really complete rewrite ,so seems like the architecture keep the same ,and the akka stream will work on the HttpMessage level. |

Added travis, and it's now passing. |

inFlight should use int
channel is only one to an event loop,and an event loop is backend by a thread,and the bind between channel<->eventloop will keep during the eventloop's lifetime.so I think it's threadsafe.why AtomicInteger?

Ah, I did not know that Netty 4 had a new thread model that made things thread safe. That should let me simplify this somewhat.

Updated - I actually removed inFlight since it can be determined from receive sequence and current sending sequence.

In addition, made the following changes to the way the handler works: * Messages are buffered in a hash map by sequence ID if it's not the right time for the sequence. * Removed subsequence ordering - writes for a given request are required to be sequential without the pipelining handler, so with it we can assume the same. * Replaced buffer limit with back pressure - if the number of in flight requests exceeds a high water mark, the handler now exerts back pressure on the client by blocking read completed events, and unblocks them, and requests a new read, when a low watermark is reached.

Apparently you need to add channelActive() override and set inactive=false, otherwise pipelining test fails because writeInSequence never puts messages into buffer thinking the channel is inactive. |
