• TcpServer, TcpSubserver and TcpClient now support epoll model (only available under Linux)
• IO multiplexing model can be switched in common.h

Byte Stream

• Use Stream instead of Message in onMessage() API
• Now support passing integers, arrays and strings directly through Stream without using a struct

Exception Information

• Log system now supports output of errno and exception information provided by the OS with LOG_PERROR

Other Updates

Log system

• Implement a asynchronous log system, support multiple warning levels

Configuration

• Server and Client Now support reading configuration files from outside
• Provide sample bat and shell scripts

Other Changes

• Upgrade client, increase scalability
• Add maximum connection limit

This version mainly enhance the stability of the server.

Heartbeat Detection

• Server now is able to actively disconnect from the client when there's no response

Timing Eending

• Server now is able to send message regularly after certain time

Safe Exit

• Use semaphore to ensure the exit order of threads
• Resources are now released properly

Other Changes

• Implement a Thread class to achieve better control of threads
• Implement a Buffer class to simplify code logics of sending and receiving messages

Smart Pointers

• Smart pointers are used in the entire solution to eliminate memory leak

Memory Pool

• Implement a maintainable memory pool defined in Memory.h
• Include Allocator.hpp to use the memory pool (not enabled by default)

Object Pool

• An object pool is included in Object.hpp

Other Changes

• Reorganized files, seperated each module
• Block SIGPIPE due to socket disconnection, able to work stably under Linux

Performance optimization

• Optimized select model
• Seperate receive thread and send thread in each subserver
• Eliminate potential memory leaks

Warning

• This version won't work on Linux or MacOS because of SIGPIPE

Multithreading

• Multithreading is used in the server. The main thread handles clients connections, while other threads handle messages.

Producer-Consumer Pattern

• Use a message queue for adding clients connections.

Event interface

• Define an event interface which provides three methods onConnection, onDisconnection and onMessage
• Custom servers can now inherit from TcpServer and implement the interface

Other features

• Improve log output
• Integrate common files

Buffering

• Add a secondary buffer to solve system buffer overflow problem with large amount of data
• Unpack sticky packages

Benchmark

• Add a benchmark to measure the performance of the server
• Modify the client to simulate a large number of client connections

• Encapsulate Zeus-Server and Zeus-Client
• Client now is able to connect to multiple servers simultaneously
• Use CMake to build

Cross platfrom

• Cross-platform client in Windows, Linux and MacOS
• Cross-platform server in Windows, Linux and MacOS

Test Environment

• Windows 10.0
• Linux 4.4.0 (WSL)
• MacOS 10.12.6

Select model

• Apply select model to server, able to handle multi-client connections
• Apply select model to client
• Use multithreads for client input
