[ANN] http-kit 2.0.0 released

[Shen, Feng]

Hello folks. 

I just released version 2.0.0 of http-kit. 

2.0.0 (2013/3/29)

1. Unify WebSocket and HTTP long polling/streaming with Channel protocol and with-channel (API breaks with the RC)
2. WebSocket support sending and receiving binary frame with byte[]
3. Support HTTP streaming
4. WebSocket message ordering is guaranteed by server

Updated documentation: http://http-kit.org/server.html

Let's build amazing realtime applications with Clojure, using http-kit.

The with-channel API is not compatible with the RC releases. The new is better and much easier to understand and use. The old's documentation can be found here

Hi, 

just released 2.1.0.

[http-kit "2.1.0"] ; Add to your project.clj.

Compare to 2.0.0, noticeable changes:

1. Much faster: about 30%~80% faster.
   
2. The client support HTTPS now
3. :as option to do client output coercion

Not that noticeable changes:

1. few minor bugs fixes
2. less RAM usage

The full update log: https://github.com/http-kit/http-kit/blob/master/history.md

Updated client documentation: http://http-kit.org/client.html

Congratulations on the release! Could you please let me know whether
HTTP-Kit has built-in support for applying backpressure, and if it
does then how to configure the same?

I'd highly recommend starting a new thread for each new version.

Also, your change log is in chronological order. Keeping it in

reverse chronological order (2.1.0 first) would make it much easier

to quickly discover recent changes.

Good job on the performance improvements!

Hi,

regarding the perf. improvements, is it client or server?

Thx

It's the server.  Due to IO model change: One IO thread (reading and writing) => One thread reading, decoding + many threads writing

If the backpressure is something like this:  http://mechanical-sympathy.blogspot.jp/2012/05/apply-back-pressure-when-overloaded.html

Then yes.  http-kit uses a bounded queue for accepting request, when too many request coming, they get queued, if the queue exceeds a certain size(control by :queue-size option), request get rejected, client will get 503.
And, there is another option :thread controls how many worker threads to compute HTTP response from request.

There is another possible problem: many requests come in short time, server compute the response (which is large) very fast(so the request did not get rejected), and the output link is slow(like low bandwidth network connection). In this scenario, the HTTP response get queued, wait for TCP buffer to flush.

Looks great, Feng Shen.
I couldn't find a road-map so I ask here. Will there be a client-side for browsers in ClojureScript or Javascript? I mean something similar to sockjs implementation.

I have't plan to do that yet.  http-kit is focused to provide a HTTP library for Clojure.
