[go-nuts] Go 1.18: reflect implicit type conversion

Hi all, In this code, the SetMapIndex line panics in Go <1.18, but it no longer panics in Go 1.18: type CustomString string m := reflect.ValueOf(map[CustomString]int{}) m.SetMapIndex(reflect.ValueOf("key"), reflect.ValueOf(0)) The panic ("value of type string is not assignable to typ

Re: [go-nuts] syscall.SetNonblock stopped working in Go 1.9.3

Thanks all. I opened this issue: https://github.com/golang/go/issues/23556 (The reason I'm using SetNonblock is that before Go 1.9, it wasn't safe to call file.Close() if another goroutine was reading/writing to the pipe. But now that it's safe with Go 1.9, I can re-organize my code and remov

[go-nuts] syscall.SetNonblock stopped working in Go 1.9.3

Hey all, this program exits (as expected) when run with macOS 10.12.6 + Go 1.8.6, but it deadlocks when run with Go 1.9.3: https://play.golang.org/p/Dw_ND9gkgPm The same behavior is observed when using unix.SetNonblock instead of syscall.SetNonblock. It appears that the SetNonblock() functio

[go-nuts] Go 1.9 poller, close os.File used by another goroutine
