When i debug go func() with dlv, use s to go into but not exec.
Who is familiar with dlv debugging go source code？
thanks！
package main
import "fmt"
func main() {
a := make(chan int)
go func() {
a <- 1
}()
for {
select {
case i, ok := <-a:
fmt.Println("a:", i, "\tStatus:", ok)
default:
fmt.Println("a over")
return
}
}
}
go build -o chan -gcflags="-N -l" chan.go
dlv exec ./chan
Type 'help' for list of commands.
