Every Go-identifier reference in // and /* */ comments now uses
godoc's [Name] linking syntax so pkg.go.dev and `go doc` render
them as clickable cross-references. No behaviour change.
Pattern applied across the tree:
In-package [Foo], [Foo.Bar]
Cross-package [pkg.Foo], [pkg.Foo.Bar]
Stdlib [netip.Prefix], [errors.Is], [context.Context]
Tailscale [tailcfg.MapResponse], [tailcfg.Node.CapMap],
[tailcfg.NodeAttrSuggestExitNode]
Skip rules:
- File:line refs left as plain text
- HuJSON wire keys inside backtick raw strings untouched
- ACL/policy syntax tokens (tag:foo, autogroup:self, ...) not Go
symbols, left as plain text
- JSON/OIDC wire keys, gorm tags, RFC IPv6 placeholders, markdown
link tags, decorative dividers — all left as-is
Extend the servertest harness with:
- TestClient.Direct() accessor for advanced operations
- TestClient.WaitForPeerCount and WaitForCondition helpers
- TestHarness.ChangePolicy for ACL policy testing
- AssertDERPMapPresent and AssertSelfHasAddresses
New test suites:
- content_test.go: self node, DERP map, peer properties, user profiles,
update history monotonicity, and endpoint update propagation
- policy_test.go: default allow-all, explicit policy, policy triggers
updates on all nodes, multiple policy changes, multi-user mesh
- ephemeral_test.go: ephemeral connect, cleanup after disconnect,
mixed ephemeral/regular, reconnect prevents cleanup
- routes_test.go: addresses in AllowedIPs, route advertise and approve,
advertised routes via hostinfo, CGNAT range validation
Also fix node_departs test to use WaitForCondition instead of
assert.Eventually, and convert concurrent_join_and_leave to
interleaved_join_and_leave with grace-period-tolerant assertions.
Add a new hscontrol/servertest package that provides a test harness
for exercising the full Headscale control protocol in-process, using
Tailscale's controlclient.Direct as the client.
The harness consists of:
- TestServer: wraps a Headscale instance with an httptest.Server
- TestClient: wraps controlclient.Direct with NetworkMap tracking
- TestHarness: orchestrates N clients against a single server
- Assertion helpers for mesh completeness, visibility, and consistency
Export minimal accessor methods on Headscale (HTTPHandler, NoisePublicKey,
GetState, SetServerURL, StartBatcher, StartEphemeralGC) so the servertest
package can construct a working server from outside the hscontrol package.
This enables fast, deterministic tests of connection lifecycle, update
propagation, and network weather scenarios without Docker.
