Cache Components: draft mode logs "Unexpected cache miss after cache warming phase" for deterministic keys (partialPrefetching)
### Link to the code that reproduces this issue https://github.com/jaytarr-geo/next-draft-mode-cache-miss-repro ### To Reproduce `repro.sh` runs `next start`, requests `/p/a` without and then with the draft-mode cookie (set by `/api/draft`), and counts the warnings. The app is a...
Default 'use cache' handler keeps a 64 KB buffer-pool slab alive per small entry, so cacheMaxMemorySize undercounts memory
...Then it reads `process.memoryUsage().arrayBuffers` after a full GC. 4. Repeat with the workaround handler: `EXACT_COPY=1 pnpm build && EXACT_COPY=1 pnpm start`, then `pnpm load`. `pnpm handler` reproduces the same thing against `createDefaultCacheHandler` directly, without a...
Performance bottleneck caused by the KMSv2 KDF cache lock
### What happened? This is a follow-up to #134002. After we removed the `RecordKeyID` lock locally, decrypt latency was still high under load. Looking again, we found a second lock on the same path, one that had been hidden behind the first. Every KMSv2 decrypt looks up its...
Segment cache: unbounded re-prefetch loop (thousands of `_rsc` requests per minute) for `<Link>`s whose dynamic segment holds a raw `:` (not percent-encoded), with optimistic routing
...no parallel route. It still loops on 16.4.0 and 16.5.0-canary.7. I found no open issue with this trigger (keyword search, so a miss is possible). Workaround: build the href with `encodeURIComponent` per dynamic segment (the loop stops: 0 requests), and `prefetch={false}` on...
