tinynet

tinynet is light-weighted network library.it supports select/poll/epoll/iocp multiplexing model. you can switch any one by define different macro.

compiler:

make sure easy project at the same directory,easey git address:https://github.com/yuyunliuhen/easy

#####linux use gcc,version 4.8.1 or later for example: g++ -g -Wl,--no-as-needed -std=c++11 -pthread -D__LINUX -D__HAVE_SELECT -o ./bin/srv_test reactor.h reactor.cc event_handle.h event_handle_srv.h event_handle_srv.cc reactor_impl.h reactor_impl_select.h reactor_impl_select.cc server_impl.h server_impl.cc ./srv_test/srv_test.cc -I../easy/src/base -I. g++ -g -Wl,--no-as-needed -std=c++11 -pthread -D__LINUX -D__HAVE_EPOLL -o ./bin/srv_test reactor.h reactor.cc event_handle.h event_handle_srv.h event_handle_srv.cc reactor_impl.h reactor_impl_epoll.h reactor_impl_epoll.cc server_impl.h server_impl.cc ./srv_test/srv_test.cc -I../easy/src/base -I. g++ -g -Wl,--no-as-needed -std=c++11 -pthread -D__LINUX -D__HAVE_POLL -o ./bin/srv_test reactor.h reactor.cc event_handle.h event_handle_srv.h event_handle_srv.cc reactor_impl.h reactor_impl_poll.h reactor_impl_poll.cc server_impl.h server_impl.cc ./srv_test/srv_test.cc -I../easy/src/base -I. you alse can use camke,just execute $cmake . & make #####windows cmake -G "Visual Studio 11 Win64" . or call build_x64/x86.bat

usage:

####for example: #####server: int main(int __arg_num,char** args) { if(3 != __arg_num) { printf("param error,please input correct param! for example: nohup ./transform 192.168.22.63 9876 & \n"); exit(1); } #ifdef __LINUX signal(SIGSEGV,dump); #endif // __LINUX char* __host = args[1]; unsigned int __port = atoi(args[2]); Reactor* __reactor = Reactor::instance(); Server_Impl __event_handle_srv(__reactor,__host,__port); static const int __max_time_out = 50001000; __reactor->event_loop(__max_time_out); return 0; } #####client: int main(int argc, char argv[]) { /* g++ -g -Wl,--no-as-needed -std=c++11 -pthread -D__LINUX -D__HAVE_SELECT -o cli_test reactor.h reactor.cc event_handle.h event_handle_cli.h event_handle_cli.cc reactor_impl.h reactor_impl_select.h reactor_impl_select.cc client_impl.h client_impl.cc cli_test.cc -I../easy/src/base / if(3 != argc) { printf("param error,please input correct param! for example: ./tinynet_cli 192.168.22.63 9876 \n"); exit(1); } char __host = argv[1]; unsigned int __port = atoi(argv[2]); Reactor* _reactor = Reactor::instance(); Client_Impl* client_impl = new Client_Impl(__reactor,__host,__port);

}

press test

(1)use echo c/s model,sends ten packets per/second,100 bytes per/packet,include 12 bytes head size and content;
(2)test under linux,about 5 connection per/second,20000 connections in all.to test program' s stability and the number of connections,just include data sending and parsing,do nothing others.
