GOPLS SPRING CLEANING REMOVES DEAD CODE, FIXES GENERIC METHOD BUGS

By RepoJournal · Filed 22:41 UTC on June 8, 2026 · About Go

The tools team is shipping a lean gopls release that kills unused commands and fixes a critical bug in SSA generic method handling that was breaking analysis across the entire ecosystem.

gopls/internal/cmd is dumping the 'gopls bug' subcommand [1], a feature nobody has ever actually used. Meanwhile, the real work is happening in go/ssa [2], where a fix for RuntimeTypes now correctly rejects generic methods that shouldn't appear in MethodSet, closing two long-standing bugs that were corrupting analysis pipelines. The filewatcher is getting lighter too [3], with an orphaned interval field finally removed after it became non-configurable months ago. Over in golang/net, HTTP/3 is gaining gzip support to match HTTP/1 and HTTP/2 parity [4], while SVCB/HTTPS record validation is being fixed to properly enforce parameter ordering [5]. The crypto/x509 package is getting smarter about IPv6 zone-scoped addresses [6], using netip.ParseAddr instead of the older net.ParseIP that was silently failing on zone IDs. VS Code's Go extension is pinning format-on-save mode to 'file' [7] because gopls doesn't support range-based formatting, preventing silent incompatibility headaches for developers using other editors' defaults.

Action items
