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
Replace zcache with golang-lru/v2/expirable for both the state auth
cache and the OIDC state cache. Add tuning.register_cache_max_entries
(default 1024) to cap the number of pending registration entries.
Introduce types.RegistrationData to replace caching a full *Node;
only the fields the registration callback path reads are retained.
Remove the dead HSDatabase.regCache field. Drop zgo.at/zcache/v2
from go.mod.
