golang-supervisor

Small tool to automate start small background process that look for main process and launch new one if there is a crash

Usage

just import this package on top of your application imports, like this:

import (
_ "github.com/hhh0pE/golang-supervisor"
"log"
"os"
"strings"
"io"
"os/exec"
"flag"
"fmt"
"time"
)

About other takes care golang-supervisor. It will create 2 copy of source executable: [exeName].supervisor and [exeName].running and.

Supervisor works simple:

if .running executable fails with code different from 0(zero means everything is okey), supervisor will restart .running executable immediately (but supervisor will copy executable from [exeName] to [exeName].running again, so it can be use for easily restart app).

Also you can get original executable name(without .running and .supervisor suffix) with method golang_supervisor.OriginalExecutablePath().
