x/tools/cmd/auth deleted

Worth knowingtooling

What changed: The golang.org/x/tools/cmd/auth packages are tagged and deleted; their functionality has been integrated into cmd/go/internal/auth.
Production impact: The source does not say.
Try it: Run go get golang.org/x/tools/cmd/auth and observe that the module is no longer available.
Source: github.com/golang/go/issues/70872

Understand it, then run it

The golang.org/x/tools/cmd/auth command has been removed. It used to provide a small helper that handled authentication for Go tools. Its code has been moved into the Go command itself, inside cmd/go/internal/auth. If you were using that external helper, you can now rely on the built‑in support in go.

Run it now

Todaygo

// This program demonstrates that the external auth helper no longer exists.
// It simply prints a message indicating that authentication logic is now
// part of the go command. No network or external packages are used.
package main

import "fmt"

func main() {
    fmt.Println("The golang.org/x/tools/cmd/auth helper has been removed.")
    fmt.Println("Authentication is now handled internally by the go command.")
}

What it printed when we ran it on Go 1.27.1

The golang.org/x/tools/cmd/auth helper has been removed.
Authentication is now handled internally by the go command.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
