Go: Networking Fixes and Transport Rewrite

Networking dominates with faster Linux interface lookups, clearer errors, a hijack leak fix, and a rewritten HTTP transport pool, alongside contract-preserving fixes for JSON, database SQL, and mail.

Good morning, it's October 21st, 2026.

The big signal today is the network stack getting both faster and safer, with smaller correctness fixes elsewhere to keep long-standing behavior predictable.

First, networking efficiency and reliability. A daemon resolving interface names on every event was paying the cost of a full link dump on Linux for each lookup. Pull request 82382 asks the kernel for just that one link, cutting idle CPU that grew with host size. Paired with that, pull request 82384 puts the…

Second, honoring contracts. Pull request 82369 aligns JSON version two with version one for unnamed types, skipping promoted unmarshal methods and decoding embedded fields instead, to avoid a silent behavior change. In the database S Q L layer, pull request 82368 closes a race between grabbing a connection and…

Finally, quiet speed-ups. Commit 5a04417 trims about nine percent off base sixty-four encoding, and commit ace5a75 makes the synctest bubble check inlinable, cutting Wait Group add overhead by up to twenty percent in benchmarks.

What's next: watch the new transport pool for subtle pooling regressions, and expect more JSON version two alignment work.
