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
When stale-send cleanup prunes a connection from the batcher, the old serveLongPoll session needs an explicit stop signal. Pass a stop hook into AddNode and trigger it when that connection is removed, so the session exits through its normal cancel path instead of relying on channel closure from the batcher side.
When the batcher timed out sending to a node, it removed the channel from multiChannelNodeConn but left the old serveLongPoll goroutine running on that channel. That left a live stale session behind: it no longer received new updates, but it could still keep the stream open and block shutdown.
Close the pruned channel when stale-send cleanup removes it so the old map session exits after draining any buffered update.
