I found the position of `[0]byte` in the struct matters. type bar2 struct { A int _ [0]byte } differs from type bar3 struct { _ [0]byte A int } see the full example On Wednesday, July 12, 2017 at 10:44:04 AM UTC+8, Rader wrote: > > they both have the

they both have the same size, eg. following structs bar and bar2 both take 16 bytes memory on a x64 machine. package main import ( "fmt" "unsafe" ) type bar struct { A int _ bool } type bar2 struct { A int _ [0]byte } func main() { bar := bar{} bar2 := bar2{}

The key word is simple. We wanted a minimum possible logging library that is easy to use and efficient, with the expectation that those wanting fancier, richer libraries could build their own and debate the right interface. That is exactly what has happened. See https://github.com/golang/glog for

This caught me out recently; there's definitely a gap in my understanding as to how select works. Maybe it's caught other people out too? For one of my clients, I'd written an application that would try to read data from a backend. There were multiple instances of this backend (say one in Orego

Am I the only one who finds the log standard library a tad lacking? I expected to be able to set log verbosity, like logger.Debug, logger.Info, etc, and I expected thread safety. I noticed today that my log output from multiple loggers in different goroutines was interlaced. I wonder if I'm usi

I am trying to test a proxy that is expecting an SSL handshake immediately, even if the client is going to use an SSL CONNECT method. The problem is that my Golang and Python test code both seem to have the same flaw. They connect to the proxy in the clear, and then issue a CONNECT, but the prox
