Asynchronous multithreaded C/s framework Gko_pool

Once in the home company did an intranet-to-peer transmission tool name Yue Gingko at that time too food, the network part write is poor, all kinds of blocking network communication later left to memcached code research, feel inside the network model is very advanced I took Memcached's network part out and Gingko did a combination, wrote a network framework called Gko_pool General features are:

• Fully asynchronous (including DNS resolution)
• Can listen a port when server, can also initiate connection write client
• Worker is peer multi-threaded
• Built-in a simple "memory pool"

See Code found memcached state machine has a logical bug to give memcached a patch later this matter was forgotten, after two years by the maintainer found to master, Defenders said:

Wow, years old ... and it looks correct to me. If that update_event fails the connection might zombie. It's very hard for that to fail and it's been that forever. Pushed a commit for the next release.

It's no exaggeration to say that memecached is a monument to multi-threaded asynchronous network programming (Nginx is a monument to multi-process asynchronous network programming) I took Memcached's network part out and wrote a network framework called Gko_pool https:// Github.com/auxten/gko_pool

For a chestnut: HTTP brush ticket, in my notebook machine can also reach 300KQPS, control the speed, accidentally sina the server to hang up

In order to brush the truth of the ticket, but also write so many useragent, brush the conscience of the world, ha ha haha more examples, such as: A custom protocol client, server, etc. please go to the stability of GitHub this set of libraries do not question, has been used in many of my company's tens of thousands of servers on the network daemon
