Re: [go-nuts] Golang slow performance inside for loop MySQL Queries

Hello, I created the sql to fetch all info in one call instead of multiple calls per each row. One thing I noticed about golang is that when I ping my Remote DB from localhost (running in vscode) I get ping -> 1.573826274s. So I think this is the reason that all my calls to db are delayed. Hav

I'm a C programmer so maybe this is a dumb question but, why does this code in runtime/gostring.go allocate (rawstring) then copy data (memmove) instead of just making the stringStruct.str point at the incoming data? i.e. copy the pointer instead of allocating+copying data. func gostring(p *by

[go-nuts] Question about casting

HI, Go newbie here... not sure if this is a dumb question or not :) I have a simple program: package main import "fmt" type any interface{} type myInt int func plus(a, b any) any { return a.(myInt) + b.(myInt) } func main() { s := plus(myInt(3), myInt(2)) fmt.Printf("%v, %T\n", s, s) } Outp

Thanks to both for replying. Both pieces of advice cover the use case of waiting for all goroutines to complete before exiting. I have the opposite problem. I want to end all goroutines if I exit. Is there anything in the sync package for that? On Friday, August 18, 2017 at 2:40:39 PM UTC-4, Ta

Hi, https://play.golang.org/p/lR6_mxSjtb I have two long running things to do, I'd like to do them in parallel, then sync up at the end. I've written it as a function which gets one thing done, and which backgrounds the second thing with a goroutine. Thing one has a lot of reasons to exit earl

Do you want to use Go version 1.4 specifically for some reason? If not, I'd recommend going with the most recent stable release (1.7.4). Besides the git clone/build process Dave Cheney mentioned, you can download a binary build of the compiler/tools for Linux at: https://storage.googleapis.co
