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>
2025-10-10clientupdate, util/osshare, util/winutil, version: improve Windows GUI ↵Aaron Klotz1-6/+6
filename resolution and WinUI build awareness On Windows arm64 we are going to need to ship two different GUI builds; one for Win10 (GOARCH=386) and one for Win11 (GOARCH=amd64, tags += winui). Due to quirks in MSI packaging, they cannot both share the same filename. This requires some fixes in places where we have hardcoded "tailscale-ipn" as the GUI filename. We also do some cleanup in clientupdate to ensure that autoupdates will continue to work correctly with the temporary "-winui" package variant.

2023-02-01all: update to Go 1.20, use strings.CutPrefix/Suffix instead of our forkBrad Fitzpatrick1-3/+1

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>
2022-11-21all: use strs.CutPrefix and strs.CutSuffix moreMihai Parparita1-3/+4
Updates places where we use HasPrefix + TrimPrefix to use the combined function. Updates #5309 Signed-off-by: Mihai Parparita <mihai@tailscale.com>
2022-11-04all: remove old +build tagsBrad Fitzpatrick1-1/+0
The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2021-08-17all: simplify build tags involving iOSJosh Bleecher Snyder1-2/+2
Prior to Go 1.16, iOS used GOOS=darwin, so we had to distinguish macOS from iOS during GOARCH. We now require Go 1.16 in our go.mod, so we can simplify. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
2021-08-09version: remove rsc.io/goversion dependencyJosh Bleecher Snyder1-4/+87
rsc.io/goversion is really expensive. Running version.ReadExe on tailscaled on darwin allocates 47k objects, almost 11mb. All we want is the module info. For that, all we need to do is scan through the binary looking for the magic start/end strings and then grab the bytes in between them. We can do that easily and quickly with nothing but a 64k buffer. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
2021-08-05all: gofmt with Go 1.17Josh Bleecher Snyder1-0/+1
This adds "//go:build" lines and tidies up existing "// +build" lines. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
2021-02-09portlist, version: update build tags for Go 1.16, Apple M1moncho1-1/+1
Build tags have been updated to build native Apple M1 binaries, existing build tags for ios have been changed from darwin,arm64 to ios,arm64. With this change, running go build cmd/tailscale{,d}/tailscale{,d}.go on an Apple machine with the new processor works and resulting binaries show the expected architecture, e.g. tailscale: Mach-O 64-bit executable arm64. Tested using go version go1.16beta1 darwin/arm64. Updates #943 Signed-off-by: moncho <50428+moncho@users.noreply.github.com>
2020-07-30version: revert the filepath change from earlier commitBrad Fitzpatrick1-11/+16
f81233524fddeec450940af8dc1a0dd8841bf28c changed a use of package 'path' to 'filepath'. Restore it back to 'path', with a comment. Also, use the os.Executable-based fallback name in the case where the binary itself doesn't have Go module information. That was overlooked in the original code.
2020-07-30version/cmdname: s/path/filepath/ and fix version.ReadExe() fallback.v1.1.0Avery Pennarun1-2/+3
We were using the Go 'path' module, which apparently doesn't handle backslashes correctly. path/filepath does. However, the main bug turned out to be that we were not calling .Base() on the path if version.ReadExe() fails, which it seems to do at least on Windows 7. As a result, our logfile persistence was not working on Windows, and logids would be regenerated on every restart. Affects: #620 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>
