Re: [go-nuts] Understind how to apply timeout using gouritine

Contexts are great. And if your goal is to solve a specific problem, then sometimes they may be the best solution. But you implied in your OP that you were learning go. And in that case, I would still urge you to understand your original channel based code, and why it does not work, and how to

Re: [go-nuts] Understind how to apply timeout using gouritine

The magic behind contexts is that they use a channel but without sending any data over it. Instead, *closing* the channel is a signal to terminate. This allows you to have multiple goroutines listening on the channel, and they will *all* receive the termination signal, as a broadcast. (It wou

Hi Brian, Thanks for your help. I will try out to implement your samples in my project. But still studying Goroutines and now Context. El miércoles, 26 de febrero de 2020, 10:41:26 (UTC-3), Brian Candler escribió: > > Perhaps slightly clearer: > https://play.golang.org/p/DDZxqaEFi-T > >

The code you posted above never actually called goToSleep(), because the 'strings ' channel was nil. Could you post a playground link to the new code that you are running below? On Tuesday, February 25, 2020 at 8:38:27 PM UTC-5, Juan Mamani wrote: > > Ok, you are right. But I was confused with

Edit: I said "communicate with its caller" but in practice it might as well be another goroutine or the caller of the caller, either way the construct and the logic standing behind it are exactly the same :) Le mar. 25 févr. 2020 à 09:42, Michel Levieux a écrit : > Hi Juan, > > You cannot termin

Re: [go-nuts] Understind how to apply timeout using gouritine

Hi Juan, You cannot terminate a function execution from its caller if you did not pass it an argument (most likely a channel) which it can use to communicate with its caller, and terminate itself when the timeout is reached. The simplest example I can think of is the following: https://play.golang

Your code will still not compile. In this group, it is often helpful to include a link to your code in the playground (https://play.golang.org/) using the "Share" button. That is in addition to, or instead of, posting your code in the message. This will allow others to easily run your code, but
