Coconut is C++ network framework with briefly, clearly, high performance.

• Using libevent (available for switching another network library)
• Available cross platform linux, windows (by using libevent)
• Easy multithread service
• Tcp Socket
• Unix Domain Socket(only tcp)
• Udp Socket
• Http Client (GET, POST)
• Simple Http Server
• Redis Request (optional)
• JSON Stream Protocol (optional, now unstable)

• fix -without-json option in configure.ac
• fix boost include path

Environment

• Server : single thread, Linux, Intel(R) Xeon(R) CPU L5520 @ 2.27GHz 16 cpu core

• Client : 16 thread, 1000 clients, 10000 count per a client with 256 byte, Linux, Intel(R) Xeon(R) CPU L5520 @ 2.27GHz 12 cpu core

• All server sample codes are here : https://github.com/gunoodaddy/coconut/tree/master/test/echotest

• client code is here : https://github.com/gunoodaddy/coconut/blob/master/examples/tcpclient.cpp

http:https://libevent.org/

• If you use Win32 IOCP, you must use this libevent.
• Original libevent >= 2.0.15 has a bug in evutil_tv_to_msec function. (need to add tv pointer null check code)
• And we've added free callback feature for struct evhttp_request to know which evhttp_request pointer will be freed. It needs if you should store http request and then later send responses. (like 'Commet'). You can see our fixed codes by finding gunoodaddy comment in this libevent sources.
• By running configure, it will check our free callback feature exists in your own libevent and then mark HAVE_LIBEVENT_GUNOODADDY_FIX in config.h.

boost 1.48.0 download

• You must build boost library (run b2), we need boost stage library for using boost::thread

https://github.com/antirez/hiredis

• On Win32, you must use this hiredis instead of orginal hiredis so that the build is successful.
• If you do not want to use redis, run configure --without-redis.

libjson 7.4.1 download

• In order to build successful, you must use 3rdParty/src/libjson instead upper link's libjson.
• We modified JSONStream class to parse correctly. (7.4.1 libjson has a few bug in JSONStream)
• You can find 'gunoodaddy' comment in 3rdParty/src/libjson modified codes.
• And if you use linux 64bit os, must edit <lib_json_root>/makefile to add -fPIC to cxxflags_default.
• If you do not want to use json feature, run configure --without-json.
