Re: [go-nuts] flag: bug with shared values?

There are actually multiple cases of reusing the same XXXVar for the same variables: * https://github.com/golang/go/blob/50bd1c4d4eb4fac8ddeb5f063c099daccfb71b26/src/flag/example_test.go#L29-L30 -> to support shortcuts within the same command * projects with multiple flag.FlagSet (to manage va

Re: [go-nuts] Catch/handle cgo SIGSEGV

Thank you very much! It's way more complicated than I'd to deal with, so I'll leave it as is: crash the program if the C side gots a SIGSEGV. Even the gRPC child seems more managable. Ian Lance Taylor a következőt írta (2020. szeptember 17., csütörtök, 22:11:18 UTC+2): > On Thu, Sep 17, 2020 at

Re: [go-nuts] What are the best practices for go build tools?

Hi Andi, > 1) I cannot do go install tools.go: go install takes main packages as arguments, so no, this will not work. The tools.go file (like the example you present) is simply a way of declaring a dependency on a main package through a file that will never be built (hence the +build tools const

[go-nuts] http.MaxByteReader & http: request body too large

Hello, I want to use http.MaxByteReader, but I want to know if it possible to return an package level error (like context.DeadlineExceeded) instead of create a new one (https://github.com/golang/go/blob/06f7e655d1764f5ad57bc14f82326c181c37901c/src/net/http/request.go#L1158). It seems more goi

[go-nuts] Why does interface type carries pointer to basic types but not values itself?

Lets imagine this code. ```go var i int func main() { i = 3 F(i) } var q interface{} //go:noinline func F(a interface{}) { q = a } ``` then run `go tool compile -S ~/a.go` Skipping all not related, in main function we'll see ``` 0x001d 00029 (/home/nik/a.go:6) MOVQ $3, "".i(SB)

If sum types are supported can they can be used as general parameter types, then it is possible to declare overloaded functions/methods demoed in the end of this article

Re: [go-nuts] flag: bug with shared values?
