Previously, testwrapper only retried tests explicitly annotated with flakytest.Mark. Authors don't pre-emptively mark tests that haven't flaked yet, so the first flake of a brand-new test failed CI even when a re-run would have passed. testwrapper now retries every failing test within a per-test wall-clock budget (default: 5 minute per-attempt timeout capped at 1.5x the first failure duration, 10 minute total). A test that fails and then passes on retry is reported as flaky; a test that never passes within the budget remains a real failure (exit non-zero). For flakeapp's existing log scraping, the wire format is preserved: the "flakytest failures JSON:" line is now emitted only for tests that ultimately flaked (passed on retry). Unmarked tests get a fake issue URL of the form https://github.com/{owner}/{repo}/issues/UNKNOWN where owner/repo is detected from GITHUB_REPOSITORY, the local git remote, or falls back to tailscale/tailscale. A new "permanent test failures JSON:" line is emitted for tests that never passed; flakeapp ignores it for now (a follow-up can teach it to record real failures separately). flakytest.Mark stays as an opt-in API: still useful for tracking a known-flaky test against a real issue and for TS_SKIP_FLAKY_TESTS.

Tailscale
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:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
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.
