(Original) Open the fog to see the moon-analyze the proactor mode in asio (2), asioproactor In the previous blog, we mentioned that asynchronous requests are forwarded from the upper layer to the win_iocp_socket_service object at the bottom of the service layer, which forwards requests to the Operating System (Calling windows APIs ), how does the operating system return the result to the application after processing the asynchronous request? Here, it

Mixer: An Introduction to mysqlproxy implemented with go Mixer is a mysql proxy implemented by go and supports basic mysql proxy functions. Mysql has a lot of middleware. for the existing powerful proxies on the market, I mainly examine the following: Mysql-proxy, an official mysql proxy, is unfriendly to use and requires lua customization. I am also skeptical about its stability and performance. Cob

Today, when I used pygame to play music, I encountered a strange problem. With pygame. INIT (), I couldn't hear the sound,Remove the record and try again.CodeAs follows: 1. the following code can play normally and you can hear musicImport pygame, time########## Pygame.

Green Blue has always been the main direction of Japanese style color, fresh and beautiful, quiet and elegant, but also popular style. We usually use Photoshop "optional color" and "level" and other tools to modulate the Japanese blues, you can get very good visual effects, but we can also through other ways to achieve a better and more broad goals, the so-called road to Rome. Here to introduce "channel mixer", intuitive understanding of "channel

Ace is a very mature middleware product. It is an adaptive communication environment, but it is too ambitious. There are a bunch of design patterns, and the architecture is layer after layer. It is a little difficult for beginners. ASIO is a basic asynchronous Io library developed by boost. It encapsulates socket and simplifies socket-based Program Development. Recently analyzed ASIO Source code I was sur

Summary To implement a mysql proxy, you must first understand and implement the mysql communication protocol. In this way, the proxy can be used to build a bridge between the client and the server. Mixer mysql protocol implementation mainly refer to mysql's official internal manual and use Wireshark for verification at the same time. In the process of implementation, of course, there are a lot of pitfalls. Here we will record it as a summary of the pr

Looking at the information of the Boost.asio Library of the day, it is still a little confused. For ASIO's study to continue, at the same time here also recorded the first small example of their own start. It feels better to start with a small example and then to understand what those principles are. Because the conceptual principle is too abstract, with a small example to know how to be a routine. For the ASIO library in the later study will continue

C + + Boost::asio programming-Asynchronous TCP Hello, everyone, I'm an asynchronous way. Unlike sync, I never take the time to wait for those turtle-speed IO operations, I just tell the system what to do, and then I can do something else. If the system completes the operation, the system will notify me by the callback object I gave it before.In the ASIO library, a function or method name in the asynchrono
