Go Reference

Fork of inconshreveable/go-update (unmaintained since 2016).

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 (
 "net/http"
 "github.com/contriboss/go-update"
)
func doUpdate(url string) error {
 resp, err := http.Get(url)
 if err != nil {
 return err
 }
 defer resp.Body.Close()
 return update.Apply(resp.Body, update.Options{})
}

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