selfupdate: Build self-updating Go programs

NOTE: Original work at github.com/inconshreveable/go-update, modified for the needs within MinIO project

Package update provides functionality to implement secure, self-updating Go programs (or other single-file targets) A program can update itself by replacing its executable file with a new version.

It provides the flexibility to implement different updating user experiences like auto-updating, or manual user-initiated updates. It also boasts advanced features like binary patching and code signing verification.

Example of updating from a URL:

import (
    "fmt"
    "net/http"

    "github.com/minio/selfupdate"
)

func doUpdate(url string) error {
    resp, err := http.Get(url)
    if err != nil {
        return err
    }
    defer resp.Body.Close()
    err := selfupdate.Apply(resp.Body, update.Options{})
    if err != nil {
        // error handling
    }
    return err
}

Features

  • Cross platform support (Windows too!)
  • Binary patch application
  • Checksum verification
  • Code signing verification
  • Support for updating arbitrary files
