An interview question about recover in golang

Write the following logic , Call every second proc And ensure that the program does not exit

package main

func main() {
    
    go func() {
    
        // 1  You need to write an algorithm here 
        // 2  Call every second proc function 
        // 3  Request that the program cannot exit 
    }()

    select {
    }
}

func proc() {
    
    panic("ok")
}

Please code by yourself , Completion algorithm . The answer is at the end of the article

func main() {
    
	go func() {
    
		// 1  You need to write an algorithm here 
		// 2  Call every second proc function 
		// 3  Request that the program cannot exit 

		for {
    
			t := time.NewTicker(time.Second)
			select {
    
			case <-t.C:
				go func() {
    
					defer func() {
    
						if r := recover(); r != nil {
    
							fmt.Printf("%s\n", r)
						}
					}()
					
					proc()
				}()
			}
		}

	}()

	select {
    }
}

What is the problem with the following implementation ：

func main() {
    
	go func() {
    
		// 1  You need to write an algorithm here 
		// 2  Call every second proc function 
		// 3  Request that the program cannot exit 

		defer func() {
    
			if r := recover(); r != nil {
    
				fmt.Printf("%s\n", r)
			}
			main()
		}()

		for {
    
			t := time.NewTicker(time.Second)
			select {
    
			case <-t.C:
				proc()
			}
		}

	}()

	select {
    }
}

The stack space will be larger and larger , Know stack overflow , Program crash

In order to verify , Let's get rid of the timer

func main() {
    
	go func() {
    
		// 1  You need to write an algorithm here 
		// 2  Call every second proc function 
		// 3  Request that the program cannot exit 

		defer func() {
    
			if r := recover(); r != nil {
    
				// fmt.Printf("%s\n", r)
			}
			main()
		}()
		
		proc()
	}()

	select {
    }
}

Run the program , Observe the memory space occupied by the process , It gets bigger and bigger , Less than a few seconds , The program was killed by the system

$ ./solution26 

 Have killed
