2026-01-23all: remove AUTHORS file and references to itWill Norris1-1/+1
This file was never truly necessary and has never actually been used in the history of Tailscale's open source releases. A Brief History of AUTHORS files --- The AUTHORS file was a pattern developed at Google, originally for Chromium, then adopted by Go and a bunch of other projects. The problem was that Chromium originally had a copyright line only recognizing Google as the copyright holder. Because Google (and most open source projects) do not require copyright assignemnt for contributions, each contributor maintains their copyright. Some large corporate contributors then tried to add their own name to the copyright line in the LICENSE file or in file headers. This quickly becomes unwieldy, and puts a tremendous burden on anyone building on top of Chromium, since the license requires that they keep all copyright lines intact. The compromise was to create an AUTHORS file that would list all of the copyright holders. The LICENSE file and source file headers would then include that list by reference, listing the copyright holder as "The Chromium Authors". This also become cumbersome to simply keep the file up to date with a high rate of new contributors. Plus it's not always obvious who the copyright holder is. Sometimes it is the individual making the contribution, but many times it may be their employer. There is no way for the proejct maintainer to know. Eventually, Google changed their policy to no longer recommend trying to keep the AUTHORS file up to date proactively, and instead to only add to it when requested: https://opensource.google/docs/releasing/authors. They are also clear that: > Adding contributors to the AUTHORS file is entirely within the > project's discretion and has no implications for copyright ownership. It was primarily added to appease a small number of large contributors that insisted that they be recognized as copyright holders (which was entirely their right to do). But it's not truly necessary, and not even the most accurate way of identifying contributors and/or copyright holders. In practice, we've never added anyone to our AUTHORS file. It only lists Tailscale, so it's not really serving any purpose. It also causes confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header in other open source repos which don't actually have an AUTHORS file, so it's ambiguous what that means. Instead, we just acknowledge that the contributors to Tailscale (whoever they are) are copyright holders for their individual contributions. We also have the benefit of using the DCO (developercertificate.org) which provides some additional certification of their right to make the contribution. The source file changes were purely mechanical with: git ls-files | xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g' Updates #cleanup Change-Id: Ia101a4a3005adb9118051b3416f5a64a4a45987d Signed-off-by: Will Norris <will@tailscale.com>

2023-05-07version: properly handle vcs.modified when it's "false"Chenyang Gao1-1/+1
Current code will set the "dirty" field of VersionInfo always "true" if vcs.modified flag is there. No matter whether the flag is "true" or "false". It will make sense to set this field due to vcs.modified value, not only the existence of the key. Signed-off-by: Chenyang Gao <gps949@outlook.com>

2023-02-10version: undo previous "optimization", do more work lazilyDavid Anderson1-111/+37
Commit 59c254579ea63c669ffb3b5031e51288422c5194 moved a lot of work from functions that could be eliminated at compile time (because tests against runtime.GOOS are compile-time constant), into code that must always run before main(). So, revert that, and instead optimize the package only by moving the remaining string processing code behind sync.Onces. Signed-off-by: David Anderson <danderson@tailscale.com>

2023-01-27all: update copyright and license headersWill Norris1-3/+2
This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>
2023-01-20version, cmd/tailscale: add version.Meta, tailscale version --jsonBrad Fitzpatrick1-1/+1
Add `tailscale version --json` JSON output mode. This will be used later for a double-opt-in (per node consent like Tailscale SSH + control config) to let admins do remote upgrades via `tailscale update` via a c2n call, which would then need to verify the cmd/tailscale found on disk for running tailscale update corresponds to the running tailscaled, refusing if anything looks amiss. Plus JSON output modes are just nice to have, rather than parsing unstable/fragile/obscure text formats.
