To examine the call stack and function calls in Go debugging, you can follow these steps:
Use a debugger: Go provides several debugging tools. One popular option is Delve, which is a powerful debugger specifically designed for Go programs.
Install and configure Delve: Begin by installing Delve using the go get command: go get -u github.com/go-delve/delve/cmd/dlv. Once installed, you can use Delve to debug Go programs.
Set a breakpoint: To examine the call stack and function calls, you need to set a breakpoint in your code. You can do this by adding the line debug.Debugger() to your Go code where you want the breakpoint to be. For example:
package main
import "runtime/debug"
func main() {
debug.Debugger() // breakpoint set here
// Your code
}
Run your program in debug mode: Run your Go program with Delve by using the dlv command followed by the run command and the path to your program. For example: dlv run main.go. This will start your program and halt execution at the breakpoint.
Inspect the call stack and function calls: Once the program is paused at the breakpoint, you can examine the call stack and function calls using various debugger commands. Some useful commands include:
stack: View the call stack.goroutines: List all goroutines running in your program.list <function name>: Display the source code lines of a specific function.up and down: Move up or down the call stack.locals: Display local variables in the current scope.print <variable>: Print the value of a specific variable.Continue execution or step through code: After inspecting the call stack and function calls, you can either continue program execution using the continue command or step through the code line by line using the next command.
By using a debugger like Delve, you can effectively examine the call stack and function calls in your Go program, helping you debug and understand the flow of execution.
