go-update: Automatically update Go programs from the internet
go-update allows a program to 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.
Updating your program to a new version is as easy as:
err, errRecover := update.New().FromUrl("http://release.example.com/2.0/myprogram")
if err != nil {
fmt.Printf("Update failed: %v\n", err)
}
Documentation and API Reference
Comprehensive API documentation and code examples are available in the code documentation available on godoc.org:
Features
- Cross platform support (Windows too!)
- Binary patch application
- Checksum verification
- Code signing verification
- Support for updating arbitrary files

go-update provides the primitives for building self-updating applications, but there a number of other challenges involved in a complete updating solution such as hosting, code signing, update channels, gradual rollout, dynamically computing binary patches, tracking update metrics like versions and failures, plus more.
I provide this service, a complete solution, free for open source projects, at equinox.io.
