Go: Closing the Gaps Between Intent and Implementation
Today's changes center on correctness fixes that close gaps between what code appears to do and what it actually does, spanning a security fix in reverse proxy handling, a decades-old integer overflow bug, and stale documentation. A separate compiler thread continues trimming allocations and instruction counts across the SSA backend.

Good morning, it's July 16th, 2026.
The throughline in today's activity is code that quietly did the wrong thing until someone traced it back to its root cause. Several changes close gaps between assumed behavior and actual behavior, with real consequences for security, reliability, and documentation trust.
Start with PR 80425. Reverse proxy was forwarding h2c upgrade requests to backend servers, which lets a single connection multiplex many requests while bypassing the director and rewrite controls that operate per-request. That's a security gap now closed. Other upgrades, like WebSocket, still pass through as before.
Next, a correctness bug that's been open a long time: base64 and base32's encoded length calculation could silently overflow on very large inputs, especially on 32-bit platforms, returning a negative number instead of failing loudly. Julian Soreavis's fix, closing issue 20235, makes it panic instead, with clear…
Documentation got the same treatment. Sean Liao fixed a long-standing doc comment generator bug that was rewriting straight quotes into smart quotes in generated docs, corrupting code snippets. And a separate fix corrected the description of how template's…
