GOPLS ASSEMBLY SUPPORT LANDS, GODEP REFRESH ROLLS ACROSS ECOSYSTEM

By RepoJournal · Filed · About Go

The Go toolchain just got smarter about assembly files, and a coordinated dependency update is rolling through every major repo simultaneously.

Gopls now supports CompiledAsmFiles in its cache.Package, closing a gap for projects that blend Go and assembly [1]. This lands alongside a coordinated refresh of golang.org/x dependencies across tools, benchmarks, perf, and net repos [2][3][4][6], all merged and auto-submitted in a single coordinated push. On the HTTP/3 front, golang/net implemented server read and write deadlines [5], finally enforcing ReadHeaderTimeout, ReadTimeout, and WriteTimeout on the server side. Two bugs in the main Go repo got squashed: gofmt was mangling symlinked files instead of truncating them correctly [8], and dirFS.ReadLink now returns relative paths in errors instead of absolute ones, matching the behavior of every other dirFS method [9]. The tooling updates also pulled in a tools vendor refresh via updatestd [7].
