PLAN 9 GETS ERRNO, LEGACY BUILDERS AXED, HTTP BENCHMARK FIXED

By RepoJournal · Filed · About Go · Composed from the cited sources · methodology

Go 1.27 brings syscall.Errno to Plan 9 for the first time, closing a portability gap that's forced conditional compilation on this platform for years.

The big move: syscall.Errno is now available on Plan 9 [1], shipped through two coordinated changes that made the type available and wired it into the error interface. This matters because it lets portable code treat Plan 9 like every other platform without build constraints. Tools maintainers are already adapting [2], extracting errno handling to stay compatible with Go 1.26 and earlier while the ecosystem transitions. On the cleanup side, the wiki is purging documentation for legacy DashboardBuilders and SlowBots [3], which stopped working months ago and have been confusing developers ever since. In the test suite, a recent header limit change [4] broke benchmarks that push 1,000 headers, so the fix bumps breathing room to match real-world test patterns.
