[go-nuts] Re: Best coding practice for resiliient client-server communications

[Tamás Gulácsi]

I bet on https://pkg.go.dev/github.com/rogpeppe/retry - it allows a simple 

for iter := strategy.Start(); iter.Next(ctx.Done()); {
  if err := todo(ctx); err == nil {
break
  } else if permanent(err) {
break
  }
}

[go-nuts] Best coding practice for resiliient client-server communications

[Anssi Porttikivi]

This was an interesting read: 

"Timeouts, retries, and backoff with jitter"
https://aws.amazon.com/builders-library/timeouts-retries-and-backoff-with-jitter/

I wonder what is a good practice in Go code to retry/reconnect/recover but 
not too aggressively, when connections fail or are stalling or choppy? (Not 
really AWS specific...)

Re: [go-nuts] Re: Installing a package with an associated command

['Sean Liao' via golang-nuts]

`go install github.com/your/repo/cmd/...@latest` should work

replace `latest` with specific versions (eg prereleases) if necessary

[go-nuts] Re: Installing a package with an associated command

[Peter Galbavy]

It's worth noting that @latest only works for "releases" and not for 
tags/releases labelled pre-release. Just in case anyone hits the same issue 
I did a while back! :)

[go-nuts] Re: Installing a package with an associated command

[christoph...@gmail.com]

Indeed, it works. What if there are multiple binaries to install ? Does the 
user have to type the full package name for each program he want to install 
?

Isn’t there an equivalent to "go install ./..." that installs everything in 
one simple and short instruction ?
