Pipeline - CORS preflights send Access-Control-Max-Age: browsers stop re-preflighting authed calls every 5 s. - `req.ua` is parsed on first read instead of on every request. - JSON `rawBody` reuses the parsed buffer instead of copying it. - `emitAndWait` returns early when nothing listens: no span or closure per unlistened driver call. - SQLBatcher sends a lone query on the next tick while fewer than 8 flushes are in flight, and waits `maxTimeInQueue` as before otherwise. Lone reads skip the 10/30 ms wait; batching under load is unchanged. Auth and permissions - Token-to-actor auth starts the user, session and app lookups together and checks them in the same order: fewer sequential Redis round trips per authed request. - get-user-app-token and check-app reuse the resolved app row. getOrCreateApp skips the re-select after its own insert and doesn't wait on the cache write for replica rows. - getOrCreateApp reads the race winner from the primary when its insert loses, so it no longer hands out a session that was never written. - whoami runs the email check and the OIDC/taskbar/team lookups in parallel; key order unchanged. - OIDC providers are memoized once every discovery succeeds, with one discovery fetch in flight per URL, and the Apple key is parsed once. - gui-token and sync-cookie use `req.actor.user` instead of re-reading the user. - listSessions batches app lookups. App icon probes run together, and the original-icon probe skips the lineage fallback. - Default-granted permissions are answered from config before the scan cache, and exploded options are deduped: one less Redis read per /drivers/call. - ACL resolves ancestors lazily (owners and full-access tokens skip them) and scans the node first, then the ancestors concurrently on a miss. Filesystem - Missing-path lineage lookups run 10 at a time: batch-upload path resolution drops from about 1.3 s to about 40 ms per 100 new files. - MySQL single-file inserts return the row built from the written values, falling back to the primary read: one less primary round trip per new file. - Batch thumbnails are stored with one UPDATE per chunk (200 rows or 4M chars), with a per-row fallback. - storage.quota.bonus listeners run concurrently next to the usage SUM, and the payload carries `userUuid`: quota checks and /df no longer serialize the listener reads. - readdir cache backfill is one pipeline instead of 3xN SETEX. - Profile reads skip the lineage fallback; the own profile is read alongside the user lookup. - Legacy /stat runs is_empty (new `hasChildrenByParentUid`), owner and thumbnail concurrently. - Downloads and the video proxy pipe through `pipeToResponse`: aborts release the storage stream at once with no extra 'close' listeners, and the video proxy no longer crashes on a mid-stream upstream error. - mkdir looks up target and parent together. - Upload completion reuses the session from the access check (status is still re-read before completing), and multipart signing reads it once. - Moving a shared file to Trash skips two lookups that always returned the entry itself. Drivers and events - Subscription resolvers run concurrently and are folded in registration order. - SubdomainDriver and WorkerDriver overlap independent lookups. - The events "anyone subscribed?" check is one Redis pipeline when the region is warm. - Handler publish overlaps the count with the size check. - Broadcast flushes peers concurrently over a keep-alive agent, so a slow peer no longer delays cross-region invalidations to the others. Sites, share and AI - Hosted sites resolve the owner first, then the app and root together. Site config loads only on 404s. The hosted-app query selects only the columns it uses and moves into AppStore. - shareFlags asks about the plan only when an item is shared by link only. - Share listings run the count, teams and plan reads alongside their page query. - Claude attachment cleanup no longer blocks the response. - New util `awaitLater` for promises started early and awaited later.
