Cyclone

Cyclone is a lightweight network library, It is cross-platform and high-performance

• Cross platform (Windows, Mac OS X, Linux, Android)
• Non-blocking IO + IO multiplexing, support epoll, kqueue, select
• One loop per thread + reactor model
• Mostly wait-free multi-threaded design
• Support vectored I/O and timerfd api(Linux)
• Usefull utility support(DH key exchange, AES, adler32, and more)
• Unit test and samples  

Dependencies

Cyclone depends on following libraries

• CMake, at least version 2.8
• jemalloc , Optional
• To run unit test:
  • Google Test

Cyclone has been tested with Clang (under Mac OS X), GCC 4.8+ (under Linux), Android Build Tools 25.0 and Microsoft Visual Studio 2017(under Windows 10).

Build & Test

On Linux or Mac OS X:

git clone https://github.com/thejinchao/cyclone
mkdir _build && cd _build
cmake -G "Unix Makefiles" ../cyclone
make
make test

On Windows

1. Open CMake-GUI, enter the correct directory for source code and build. Then click Configure, choose your installed version of the Microsoft Visual Studio.
2. Click generate after fixing all missing variables to generate your Visual Studio solution.
3. Open the solution and compile the code.
4. Right click the project RUN TESTS and slect Build to run unit test

On Android

Build on the windows host machine, make sure the flowing envionment variables have been set correctly. ANDROID_SDK_ROOT, ANDROID_NDK_ROOT

git clone https://github.com/thejinchao/cyclone
mkdir _build && cd _build
%ANDROID_SDK_ROOT%/cmake/3.10.2.4988404/bin/cmake.exe -G "Ninja" -DANDROID_ABI=armeabi-v7a ^
 -DANDROID_NDK=%ANDROID_NDK_ROOT% -DCMAKE_TOOLCHAIN_FILE=%ANDROID_NDK_ROOT%/build/cmake/android.toolchain.cmake ^
 -DANDROID_NATIVE_API_LEVEL=28 -DCMAKE_MAKE_PROGRAM=%ANDROID_SDK_ROOT%/cmake/3.10.2.4988404/bin/ninja.exe ^
 ../cyclone

%ANDROID_SDK_ROOT%/cmake/3.10.2.4988404/bin/ninja.exe

To run unit test, an android device with root authority is required.

adb push test/unit/cyt_unit /data/local/tmp/
adb shell chmod +x /data/local/tmp/cyt_unit
adb shell /data/local/tmp/cyt_unit

Samples

• echo a typical client/server program
• timer just show how to use timer function
• chat a simple chat room program
• socks5 a Socks5 proxy server(only support tcp protocol)
• relay a interesting socket tunnel utility, support n:1, 1:n, key-exchange and aes encrypt.
• filetransfer Transfer a file to another machine as soon as possible
