muduo source code analysis of poller/EpollPoller multiplexing class
Introduction Poller is an abstract virtual base class of the I/O multiplexing interface, which encapsulates the I/O multiplexing API. Muduo provides EPollPoller and PollPoller derived classes (epoll and poll), so select is not supported. newDefaultPoller() selects epoll by default Main interface poll It is the core function of Poller. Use poll or epoll_wait of derived […]
Muduo source code analysis of EventLoop event loop class
Introduction EventLoop.cc is equivalent to a reactor, function calling between multiple threads (waking up with eventfd), epoll processing, timeout queue processing, and channel processing. The process running the loop is called an IO thread. EventLoop provides some APIs to ensure that the corresponding functions are called in the IO thread, to ensure that variables not […]
Muduo source code analysis: AsyncLogging asynchronous log class
Introduction AsyncLogging is muduo’s log. If the program directly writes logs to files, it may be blocked. The muduo front-end has designed two BufferPtrs, namely currentBuffer_ and nextBuffer_, and a vector (buffers_) that stores BufferPtr. Multiple front-end threads write data to currentBuffer_. When currentBuffer_ is full, put it into buffers_ and notify the back-end thread […]

Log database model component Muduo log library consists of front-end and back-end. The muduo log library is an asynchronous high-performance log library. Its performance overhead is about 1.0us~1.6us for each log […]
Muduo source code analysis channel channel class
Introduction Channel is the event distributor in muduo. It belongs to only one EventLoop. The Channel class stores the type of IO event and the corresponding callback function. Each channel is only responsible for one file descriptor, but it does not own this file descriptor. The channel plays a communication role between epoll and TcpConnection, […]
