Should I just try to read or write and check if err is nil? That thread " Best way to reliably detect that a TCP connection is closed ", using net. Update tuxedo25 mentions in the comments :. In go 1. You must read at least one byte. See commit 5bcdd63 and go issue Just try to read from it, and it will throw an error if it's closed. Handle gracefully if you wish! There is a general lack of official support to detect whether a server closed a TCP connection if the server does not write on the connection reading will fail, but writing won't.

This is based on the above mysql connCheck, but that one does a 1-byte read syscall, which can potentially conflict with other goroutines attempting to read a stream.

As a beginner to golang and nano, I'm having a lot of trouble understanding it. Eg; While handling a message, the handler will receive two arguments, session corresponding a client and a message is the payload of this request that unmarshals by nano automatically.

Compatible with Unity. Couldn't see anything in the documentation about this. Is it possible to run a HTTPS server and WSS on the same port but under different directories, or would you need to use another server on top to accomplish that? Hprose is a cross-language RPC. This project is Hprose 2. This lib looks very cool but I wonder what it actually does and how? Evpp has sadly been abandoned somehow, so this could be a good replacement for it.

Can you please write the documentation in English and explain the features, what it does and how it does it?

Written in Go. Single executable file. No runtime dependency. Simple usage: start the server then launch the client pointing to server's address. Spawns multiple concurrent lightweight goroutines to handle multiple parallel traffic streams.Go is known to be a very capable systems programming language. Inside the net package, there are a bunch of concrete types that support TCP. If you are curious, take some time to explore them.

Dial returns the Conn interface, which in turn supports Read and Write methods. Conn supports the super popular io. Reader and io. We notice that net.

The second argument to net. Dial is just our destination address. Pretty straight forward ha? The only difference was the first argument to the net. The code is simple and straight forward, it only needs some basic understanding of TCP servers: You listen to incoming connections, you accept them when they come, then you handle the connection by reading and writing data on it.

It supports io. Writer which makes it compatible with a wide variety of Go packages out there. For UDP servers, we use net. Instead it supports two special methods for reads and writes which are ReadFrom and WriteTo. Interested to learn more about Go? It provides a unique combination of covering deep internal aspects of the language, while also diving into very practical topics about using the language in production environments.
