[go-nuts] Re: Why is there no standard `uuid` package?
It's very reasonable, and as an actual decision, we fork that lib. I understood that a stability of library is not so problem. However, as Henry says, default UUID specification is defined on RFC. Implementing it is useful, isn't it? 2018年2月9日金曜日 12時28分16秒 UTC+9 Dave Cheney: > > Your argument that the stdlib grows a uuid package is really a call for > stability. “3rd parties cannot provide us the stability we need, so the go > team must”.

[go-nuts] Re: Why is there no standard `uuid` package?
Thanks you for the opinion. My colleagues are using satori/go.uuid, with web framework, "goa". API breaking change broke that package and our team had trouble for versioning. https://github.com/satori/go.uuid/issues/66 I know it is not the problem of the code of uuid generation itself, but my friends in other companies also had the same problem, or they create an original generator. it is just the reinventing the wheel so I asked why go has no standard uuid package. it's sure that defining the default format, but except for large-scaled system, generally you can be satisfied with a plain "securerandom" string, can't you? 2018年2月9日金曜日 11時10分52秒 UTC+9 Dave Cheney: > > But that’s the problem, who’s default uuid format is chosen?

[go-nuts] Re: Why is there no standard `uuid` package?
I agree UUID is vague but supplying "default" UUID generator on the standard package is significant. If you'd like to use advanced ID generator, like snowflake, you can use that package. The problem is there is no stable and de facto standard package of it. 2018年2月9日金曜日 3時17分38秒 UTC+9 Tamás Gulácsi: > > Because UUID is both vague (what format should it be stored?

[go-nuts] Why is there no standard `uuid` package?
Recently satori/go.uuid took a breaking change of API, and some of frameworks which depend on the package. And google/uuid is unstable. Why Go doesn't have an official uuid package? Is there any load map to develop google/uuid and merge it to Go itself? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Why go does't have NullInt type on database/sql?
There are NullInt64 and NullFloat64, but not about NullInt, NullFloat. (or NullInt32 etc...) After scanning from rds, my team always convert them to int, but it seems so silly.

[go-nuts] How do you debug Go itself on VM env or Docker container?
I'm trying to debug and run `./all.bash` with VM or docker, but they don't work for several reasons. On VM, I added box of CentOS and Ubuntu, though, they cancels ./all.bash at `hardlink` testing. And on docker, it also fails cuz of the permission of host directory, which includes `src`, so they can't create temporary directories for testing.

[go-nuts] Cannot decode encrypted private key
https://github.com/golang/crypto/blob/master/ssh/keys.go#L751 This line blocks to parse private key, that encrypted and contains the encryption header. But is this necessary? So much keys maybe encrypted and this disturbs to authenticate client for ssh connection in many cases. It should alert if you must aware it's insecure to parse encrypted one, but just returns error and fails following process is a little bit overkill. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] slice: copy to zero length slice
As official doc explains, copy to zero length slice results to be empty.
package main
import "fmt"
func main() {
src := []int{1, 2, 3}
dst := []int{}
fmt.Println(len(dst))
copy(dst, src)
fmt.Println(src)
fmt.Println(dst)
// [1 2 3]
// []
src2 := []int{1, 2, 3}
dst2 := make([]int, len(src))
copy(dst2, src2)
fmt.Println(src2)
fmt.Println(dst2)
// [1 2 3]
// [1 2 3]
}
But it seems unusual, is it should be like following?
package main
import "fmt"
func main() {
src := []int{1, 2, 3}
dst := []int{}
fmt.Println(len(dst))
copy(dst, src)
fmt.Println(src)
fmt.Println(dst)
// [1 2 3]
// [1 2 3]
}
