Asynchronous multithreaded C/s framework Gko_pool

Once in the home company has done a network-to-peer transmission tool name Yue Gingko

More examples, such as: A client of a custom protocol, server, etc. please go to GitHub
The stability of this library is not to be questioned, has been used in my company's tens of thousands of servers in many network daemon

A long time ago, when too much food, the network part of the poor writing, all kinds of blocking network communication
Later left the memcached code to study a bit, feeling that the network model is very advanced
I took the network part of Memcached and Gingko did a combination, wrote a network framework called Gko_pool
The approximate characteristics 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 find memcached state machine There's a logical bug that's got a patch for memcached.
Later this was forgotten, and after two years the maintainer found it on the master, as the 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 it as a network framework called 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
