Simon Law 6ff761c5f8 cmd/tailscale/cli/jsonoutput: fix flag parsing for boolean values (#19996)
SchemaVersion didn’t actually parse boolean values properly, so
calling `tailscale lock status --json=false` would fail with:

	invalid boolean value "false" for -json: invalid integer value passed to --json: "false"

This patch makes SchemaVersion.Set delegate to flag.FlagSet for its
argument parsing, with accompanying tests that ensure that both
boolean and integer values are parsed properly.

It also removes the restriction that prevented the flag from appearing
multiple times in the arguments list. Now, the final flag clobbers all
previous ones, aligning this behaviour with the standard flag package.

We also change the SchemaVersion.String output for the zero value to
"false", so that the default help message doesn’t change when we
switch other commands over from their boolean representations:

	user@host:~$ tailscale whoami --help
	FLAGS
	  --json, --json=false
	        output in JSON format (default false)

Updates #17613

Private WireGuard® networks made easy

Overview

This repository contains the majority of Tailscale's open source code. Notably, it includes the tailscaled daemon and the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows, macOS, and to varying degrees on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.

Other Tailscale repos of note:

For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.

Using

We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.

Other clients

The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.

Building

We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)

go install tailscale.com/cmd/tailscale{,d}

If you're packaging Tailscale for distribution, use build_dist.sh instead, to burn commit IDs and version info into the binaries:

./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled

If your distro has conventions that preclude the use of build_dist.sh, please do the equivalent of what it does in your distro's way, so that bug reports contain useful version information.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.

Contributing

PRs welcome! But please file bugs. Commit messages should reference bugs.

We require Developer Certificate of Origin Signed-off-by lines in commits.

See commit-messages.md (or skim git log) for our commit message style.
