prometheus/common v0.66/v0.67 introduced a mandatory model.ValidationScheme on expfmt.TextParser as part of prepping for UTF-8 metric/label names in Prometheus 3.0. The zero value is intentionally UnsetValidation, which panics on the first call to IsValidMetricName / IsValidLabelName with Invalid name validation scheme requested: unset so the long-standing "var parser expfmt.TextParser" pattern crashes at runtime. Several big downstreams have hit the same sharp edge: https://github.com/thanos-io/thanos/issues/8823 https://github.com/grafana/loki/pull/21401 Switch our two callers (parseMetrics in tsnet's TestUserMetricsByteCounters and the client-metrics scraper in tstest/natlab/vmtest) to the new expfmt.NewTextParser constructor with model.LegacyValidation. LegacyValidation matches the classic ASCII metric/label naming rules that tailscaled's exporter uses today; if and when we ever emit a metric with a UTF-8 name, we can revisit. Goes to v0.69.0 (the latest at the time of writing) rather than v0.67.5 so we pick up the unrelated security fixes for cross-host redirects. Done in advance so a follow-up change can pull in github.com/tailscale/policybottest (which depends on palantir/policy-bot, which transitively requires prometheus/common at v0.67+) without dragging this debugging into that PR.

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.
