`--watch` should start new process after old process stopped

[trim21]

• Task version: 3.36.0
• Operating system: debian 10
• Experiments enabled: no

I have a simple go program

package main

import (
	"io"
	"log"
	"net/http"
)

func main() {
	http.HandleFunc("/", func(writer http.ResponseWriter, r *http.Request) {
		print(r.URL.Query().Encode())
		io.WriteString(writer, "hello world 2")
	})

	log.Fatal(http.ListenAndServe(":8001", http.DefaultServeMux))
}

and task file:

version: 3

tasks:
  s:
    sources:
      - '*.go'
    cmd: go run main.go

whan I run it with task s --watch I encounter a error with 2024/05/02 13:38:59 listen tcp :8001: bind: address already in use.

It looks like task didn't stop old process cleanly before it start a new process?

this works as expected

version: 3

tasks:
  build:
    sources:
      - '*.go'
    generates:
      - out
    cmd: go build -o out main.go

  s:
    deps: [ build ]
    cmd: ./out

I can confirm that this works but the first one not

this works as expected

version: 3

tasks:
  build:
    sources:
      - '*.go'
    generates:
      - out
    cmd: go build -o out main.go

  s:
    deps: [ build ]
    cmd: ./out

Hello, I would like to point out that this problem stills occurs. The second configuration works because there's retries, but there's still fail message

2025/07/22 14:53:41 listen tcp :8080: bind: address already in use
task: Failed to run task "run-website": exit status 1

and sometimes it requires to save the files multiple times to force more retry because the 3 retry in case of an error are not enough and the previous process has not stopped yet. It would be good to either ensure the previous process stopped, or add a delay between the retry
