Next.js Daily: Building Garbage Collection From the Ground Up
Three linked pull requests from Luke Sandberg lay the groundwork for garbage collection in Turbopack's task caching system, introducing delete support at both the storage and persistence layers. Separately, a cluster of smaller fixes address correctness issues in middleware redirects, standalone server environment handling, and metadata rendering consistency.

Good morning. It's August 17th, and here's what moved the Next.js codebase forward.
The headline today is infrastructure work for garbage collection in Turbopack's task backend. Three pull requests from Luke Sandberg form a single stack. PR 96929 adds tombstone support to turbo-persistence, letting the database actually delete key-value pairs from multi-value tables instead of only overwriting…
A second theme is defensive fixes to request handling. PR 97441 fixes a crash when middleware returns a relative Location header — previously that threw an unhandled error instead of resolving against the request URL. PR 97435 closes a prototype-pollution-style bug in query string parsing, where parameter names like…
Worth noting separately: PR 97255 anchors async local storage instances to global symbols instead of relying on module identity, fixing a real bug where the same module evaluated through different paths created duplicate storages — meaning code inside a scope could lose access to its own store. And on the metadata…
What's next: watch for the follow-up PR that actually emits task deletions using this new tombstone plumbing — that's when garbage collection goes live. That's the…
