epoll implementation for connections in Linux, MacOS and Windows

epoller

epoll implementation for connections in Linux, MacOS and Windows.

Its target is implementing a simple epoll lib for nework connections, so you should see it only contains few methods about net.Conn:

type Poller interface {
	// Add adds an existed connection to poller.
	Add(conn net.Conn) error
	// Remove removes a connection from poller. Notice it doesn't call the conn.Close method.
	Remove(conn net.Conn) error
	// Wait waits for at most count events and returns the connections.
	Wait(count int) ([]net.Conn, error)
	// Close closes the poller. If closeConns is true, it will close all the connections.
	Close(closeConns bool) error
}

Inspired by 1m-go-websockets.

epoller's Issues

Deadlock in Wait() and WaitWithBuffer()

The code seems dead lock, the same in WaitWithBuffer()

The net.Conn it returns is no longer the original net.Conn object

After updating to version 1.0.0, we've encountered a change in the behavior of WaitWithBuffer(). The net.Conn it returns is no longer the original net.Conn object. This can cause issues because we used to associate certain state information with the Connection object, but now we can't identify or access this state information using the returned net.Conn. As a result, it's becoming challenging to integrate with our actual application.

I suggest that we transform connImpl into a publicly accessible struct provided by epoller, for example, let's call it ConnInfo. Additionally, we should provide methods to retrieve the original net.Conn object to address this need in our application. This will help us maintain compatibility and ensure a smoother integration process.

How to exclude Windows / CGO dependency?

Hi, we don't want to have CGO as dependency. For windows we want to provide a non epoll solution. Is there a way to use this library, excluding windows support without forking the library?

maybe cgo can solve the problem
