- POST /api/auth/opaque/login/ke1 (public) — takes {userIdentifier, startLoginRequest}, resolves the identifier via the same @-dispatch as legacy login (AuthApplicationService::lookup_user_for_login, factored out), fetches envelope, runs ServerLogin::start (real branch for known users, dummy branch for anti-enum on unknown/unregistered), stashes state under a random exchange_id in the moka cache, returns {exchangeId, loginResponse}.
- POST /api/auth/opaque/login/ke3 (public) — atomic take from the cache FIRST (anti-enum + anti-replay), then decodes the payload, runs ServerLogin::finish, stamps opaque_migrated_at (Phase 3 signal), and mints a session via the new AuthApplicationService::mint_session_for_authenticated_user helper — returns the same AuthResponseDto shape as legacy login so the SPA has one downstream handler.
- Session mint factored: mint_session_for_authenticated_user(User) extracted from login() so both the legacy password path and OPAQUE KE3 converge through one implementation.
- OpaqueRepositoryPort::mark_migrated with COALESCE-preserving idempotent stamp of opaque_migrated_at.
- opaque-setup CLI + Dockerfile wiring already shipped (Step 0 hygiene).
- Routing fix: sub-prefix split (/api/auth/opaque/register vs /api/auth/opaque/login) — axum composes middleware between sibling nests at the same prefix, which was cross-applying auth+CSRF to my public login routes. Distinct prefixes side-step that cleanly. Documented in both main.rs and the router builder doc.
- Rate-limit sharing: login KE1/KE3 layered with the SAME login_limiter instance as legacy POST /api/auth/login, so an attacker can't halve the per-IP budget by spraying both endpoints.
Anti-enum + anti-replay hardening in KE3: take runs BEFORE payload parse so:
- Unknown / expired / already-consumed exchange_id → 401 InvalidCredentials (same shape as wrong-passphrase, no payload-shape leak)
- Consumed handle can't be re-used to spam parse attempts
if target blob already exists, migration will check the blob
if header is already with the targeted key (or no key if not ciphered) no need write
otherwise write the blob (that will convert any blob with no header into the correct version)
- provide is_shared and is_favorite information in DTO, information propagated as badge/buttons per items
regarding performances I try to be minimalis on SQL to prevent any perf regression
- remove old set of sharedids and favoriteids (was not functionnal anymore)
- fix date picker (no past selection) in grant
- fix contextmenu close on /files section
Resolve conflicts between the external-file-mounts feature and upstream's
D5/D7 refactor (per-file provenance, keyset pagination, cross-drive move
gates, resource-access hook, folder-cascade lifecycle hook).
Key resolutions:
- FolderService::new now takes (repo, authz, file_lifecycle, mount_router);
all callers + DI updated.
- FileRetrievalService / FileManagementService keep both the mount_router
and the new resource_access_hook / drive_repo / storage_usage wiring.
- list_files_batch_with_perms: adapt the mount branch from offset- to
keyset (after_name) pagination, mirroring paginate_mount_entries.
- download_file_impl: keep upstream's &HeaderMap + `impl IntoResponse + use<>`
signature, retain the mount-download branch.
- Mount DTOs: the retired `owner_id` field maps onto created_by/updated_by
(the mount owner) — the fields the frontend now uses for owner display.
- admin/+page.svelte: keep upstream's user-delete modal + the 'mounts' tab.
- Bump memmap2 0.9.10 -> 0.9.11 (RUSTSEC critical advisory fix) and
regenerate Cargo.lock against the merged Cargo.toml.
Seven behaviour-preserving allocation / copy / bandwidth cuts, each behind a
counting-allocator BEFORE/AFTER gate that exit(1)s unless AFTER allocates
strictly fewer than BEFORE (benches/ROUND29.md, examples/bench_round29_micro.rs).
- [B] Content-cache serve fast path (optimized_inner Tier 1 +
get_file_range_preloaded — the video-scrub hot path): probe the cache with a
borrow first and build the owned get_or_load args (quoted-etag / key / id
Strings) only on a miss, instead of allocating them before every probe and
discarding them on a hit. 6 -> 0 allocs per cache hit. Splits get_or_load into
get + load_and_cache so the miss path is not re-probed and the hit/miss stat
counters stay byte-identical. Also drops the unconditional content_hash/name
clones that ran for the >=10 MB streaming tier that used neither.
- [A] NextCloud REPORT emit loops: per-row href String (and format! per folder
row) -> one reused href_buf via nc_href_into / nc_collection_href_into with the
URL-encoded user computed once per page. 1497 fewer allocs on a 500-row page.
- [C] read_full: a single-frame blob is returned zero-copy instead of a second
whole-payload memcpy into a fresh BytesMut; multi-frame path unchanged.
- [D] login-lockout key: to_lowercase()+format! -> one pre-sized ASCII buffer
(non-ASCII keeps str::to_lowercase). 3 -> 1 alloc/req, byte-identical key.
- [E] NC composite-username parse: owned clone/to_string -> &str borrow of the
already-owned raw_username. 1 -> 0 alloc on the common no-marker path.
- [F] get_contacts_in_group: stop SELECTing the discarded multi-KB vcard column
(the live method ROUND25 §Q2 missed; ContactDto has no vcard field).
- [G] count_admin_users: add count_users_by_role -> scalar COUNT(*) instead of
hydrating every admin's full row (incl. up-to-512 KiB avatar + ui_preferences
JSONB) only to .len() it, on a bootstrap-polled status endpoint.
All seven gates pass; cargo fmt --check and cargo clippy --all-features
--all-targets -D warnings clean. §F/§G additionally validated against a live
PostgreSQL 16 with the full migration set (query validity, result equivalence,
600000 -> 8 byte wire delta on the admin count).

Benchmark-gated (benches/ROUND14.md); every change ships a BEFORE/AFTER
benchmark with an equivalence gate and is rolled back on regression (the
rule is encoded as a GATE FAIL exit / threshold expect).
Backend
- Q1 faces_for_file → narrow face_boxes_for_file(id, person_id, bbox) with the
caller filter pushed into SQL: drops the 2 KiB embedding BYTEA + 6 unused
columns per face. 15-face lightbox open 0.312→0.219 ms, 32 KB→840 B/req.
- A1 cookie auth uses the borrow-only extract_cookie_str (already backs CSRF)
instead of extract_cookie_value's owned String: -1 alloc/cookie request.
- A2 compute_relevance ASCII case-fold fast path vs name.to_lowercase() per
result row (Unicode fallback preserved): 1.40x, 12→3 allocs/page.
- A3 sub pre-parsed to Uuid at decode time (TokenClaims.sub_id) vs re-parsing
the 36-char claim on every request incl. cache hits: 22.7→0.7 ns.
- A4 auth + NextCloud middlewares borrow request.headers() instead of taking
axum's HeaderMap extractor (a full map clone): 2→0 allocs/authed request.
- A5 CalDAV getlastmodified via the stack rfc2822_utc (byte-identical to
chrono) vs a per-event to_rfc2822() heap String: 5→0 allocs.
- A6 CalDAV per-event href + quoted etag written into reused page buffers vs a
fresh format! pair per event: 3.48x, 240→6 allocs/40-event page.
Frontend
- F1 t() shares one frozen EMPTY_PARAMS for the no-interpolation call forms vs
a throwaway {} per call: -1 alloc/call.
- F2 favorites favoriteIds is a persistent SvelteSet with per-page add (clear
on reset) vs a brand-new set over the whole accumulated list each page:
22.3x over a 40-page drain (O(N^2)→O(N)).
Verified: cargo check --all-targets, cargo clippy -D warnings, both bench
packs (GATE PASS), frontend npm run check + vitest (4/4). ROUND14.md also
records the investigated-but-deferred backlog (music N+1, contact vcard
over-fetch, CachedBlobBackend syscalls, ResourceList.sections builder, etc.).

The app-level ETag re-check before the write still left a gap between the check and the actual UPDATE for a concurrent writer to land in.
Push the check into the write path itself: swap_blob_hash now takes an expected_hash and only applies the SET under the same FOR UPDATE row lock it already held, closing the race instead of just narrowing it. Adds ErrorKind::PreconditionFailed (412) for the CAS-miss path; PUT/WOPI/chunked-upload keep blind-overwrite semantics by passing None
Benchmark-gated (BEFORE/AFTER + equivalence/safety gate per change), same
discipline as rounds 2-12. Full write-up in benches/ROUND13.md.
Shipped:
- V1 Grouped views windowed (files route + ResourceList). The grid arm was
the last unwindowed path (trash is grouped-by-default in grid): each
swimlane now feeds its own VirtualList, outer container a flex stack.
vitest gate: 800-item grouped grid mounts <120 .file-item (was 800).
- Q1 get_users_by_ids drops the <=512 KiB avatar image + ui_preferences
JSONB (notification path never reads them). 30-member fan-out 8.60 ->
0.25 ms (34.3x), ~7.7 MB off the wire.
- Q2 Login provisioning is_empty() -> SELECT EXISTS for calendar + address
book (every login). 0.193 -> 0.170 ms, widens with owned-row count.
- Q3 Recent-access prunes only when the upsert inserted (RETURNING xmax=0)
— a re-access can't grow the set. 0.567 -> 0.324 ms (1.75x).
- L1 Locale supported-codes precomputed once vs rebuilt per anonymous
request. 616 -> 17.3 ns (35.7x), 18 -> 1 allocs.
- H1 Duplicate /api TraceLayer removed (global stack already wraps it).
1.86 -> 1.42 us/request, -6 allocs.
- H2 client_ip span field: borrow-only ClientIpDisplay vs owned String.
187 -> 173 ns, -1 alloc.
Not shipped (discipline): the "media hooks read the blob 3x" lead was a
correctness bug, not a perf dup — the raw-path metadata/faces readers
resolve only for local+unencrypted+single-chunk blobs and silently produce
nothing otherwise. Flagged for maintainers; routing through read_blob_bytes
is a correctness fix (perf-neutral-to-negative), not a benchmark-gated
perf change.

Benchmark-gated round (benches/ROUND12.md; every change ships with a
BEFORE/AFTER harness + equivalence gates, one candidate rejected by its
own bench):
DB / query shapes (bench_round12_queries):
- NC sharee search: username-only projection instead of the 21-column row
(incl. the <=512 KiB avatar) per match, + gin_trgm_ops indexes on
auth.users for the leading-wildcard ILIKE (4.98x; 54.7x with index).
- Password login: delete the redundant full-row update_user — create_session
already stamps last_login_at in its own txn (4.45x per login).
- Email-verified stamp: narrow conditional UPDATE (8.9x); OIDC repeat login
now compares profile state in memory and issues ZERO queries when nothing
changed (was: full 17-column rewrite per login).
- Refresh rotation: revoke+insert+stamp fused into one transaction via new
rotate_session port method (1.18x).
- WOPI CheckFileInfo / authorize_wopi_access: require(Read) + get_file +
check(Update) overlapped with tokio::join!, original result precedence
(cold 1.34x).
- Upload quota gate: user-envelope + drive-cap checks fused into ONE
round-trip (check_upload_quotas) — the NC chunked PUT pays this per
chunk (1.81x, 2 -> 1 queries/chunk); shared verdict evaluators keep
error shapes byte-identical.
CPU / allocs (bench_round12_micro):
- sized_json: pre-sized listing serialization replacing axum Json's 128 B
seed + doubling-realloc chain on files/folder-resources/photos/search
responses (1.40x, 13 -> 2 allocs per 500-row page; byte-identical).
- Security headers: 4 SetResponseHeaderLayer folded into the CSP middleware
pass (5 layers -> 1; 1.43x per request, -26 allocs; header set gated
byte-identical incl. 304s).
- Media capture-metadata: single-read extraction — nom-exif now parses the
buffer kamadak already read (zero-copy Bytes) and videos open once with a
kind() dispatch; per-image opens 2-3 -> 1 (1.44x warm geomean, 1.6-3.2x
cold cache; extraction outputs gated identical incl. the MIME-mislabel
track fallback).
- Chunked-upload session ops: owner gate folded into the operation's own
DashMap lookup + stack-encoded uuid compare (5 -> 3 lookups, -2 allocs,
1.28x per chunk).
Blob cache (bench_blob_cache_index + round-3 regression guard):
- CachedBlobBackend index: tokio::sync::Mutex<LruCache> -> moka::sync::Cache
with byte weigher. The mutex serialized every cached chunk read and scaled
NEGATIVELY (2.08 -> 1.07 Mops/s from 1 -> 2 readers); moka probes are
lock-free (2.17x at K=2). Byte budget now enforced by moka (manual
current_size + collect_evictions machinery deleted); eviction listener
unlinks size-evicted files only (Replaced entries keep their file —
gated). Single-flight miss gate unchanged (16 concurrent misses -> 1
fetch re-verified via the round-3 harness).
- put_blob now populates the cache BEFORE the inner backend consumes the
source file (the old order failed 100% of the time — local renames,
S3/Azure delete the source — so the first read after a whole-file put
re-downloaded from the remote); inner-put failure invalidates the entry.
Frontend (vitest gates):
- List-view thumbnails request the 150px icon rendition instead of 400px
preview into a 40px slot (~7.1x fewer pixels, ~4-5x fewer bytes per
thumbnail across list views); grid keeps preview.
Rejected by its own bench (kept as evidence in bench_round12_micro §2):
- Single-pass compression predicate: the monomorphized And-chain already
costs ~4.6 ns / 0 allocs total; the fused node measured within noise.
New migration: 20260719000000_users_search_trgm.sql (trgm indexes).
Deferred with prepared design: grouped file/grid view virtualization
(single-VirtualRows flatten, the photos pattern) — next round's headline.

Backend (each change benchmark-gated with BEFORE replicas + equivalence
gates; see examples/bench_round11_micro.rs, bench_round11_queries.rs,
bench_log_writer.rs and benches/ROUND11.md — final numbers land in the
follow-up doc commit):
- StoragePath re-representation: single canonical joined String, segments
derived on demand; File/Folder drop the duplicated path_string field
(4000→1000 allocs per 500-row listing page)
- Display classifier fusion: classify_display shares one stack-lowered
extension across the three decision trees; call sites in FileDto,
folder/favorites/recent handlers, trash, path-resolver (+ interning
where Arc::from was still used)
- /status.php and /openapi.json memoized into OnceLock<Bytes> (openapi
rebuilt a 171 KiB spec per request: 2.8 ms → 18 ns)
- NC upload-session PROPFIND: write! + pre-sized body + stack RFC2822
dates (2.3-2.6x, 2582→772 allocs at 256 chunks)
- REST download: dead FileDto clone removed (capture mime/size + move)
- CalendarEventDto/TrashedItem into_parts moves (11 KiB ical_data memcpy
gone per CalDAV row); CardDAV getlastmodified stack render
- 4xx path: borrowed ErrorResponse serialize, ErrorKind::as_str,
not_found/already_exists clone kill
- vCard emit via write!; search page moved out with into_iter skip/take;
content-hit UUIDs parsed once; group last-user check via HashSet
- RateLimiter: lock-free get + insert (and_upsert_with variant REJECTED
by benchmark); CSRF token borrow-compare + borrowed cookie extraction
- Thumbnail/preview ETags built from as_str (Debug-identical bytes)
- Encrypted backend: encrypt_in_place_detached single-buffer write path,
chunk-sized reserve in collect_stream; retry labels made lazy
- PG: deferred upload registration 3→1 round-trips (persist_file CTE
template); direct_grant_cache for Calendar/AddressBook/Playlist authz
(single-flight + set_role/clear_role invalidation); expand_user
tokio::join!; geo clusters min(uuid)::text; recluster face assignment
batched into one UNNEST update
- People recluster cosine: norms precomputed once (bit-identical gate)
- NC capabilities poll logs demoted to debug; tracing-appender dep added
for the log-writer benchmark
Frontend:
- ResourceList.selectedEntries O(N)-per-toggle → id-index projection
O(k log k); favorites/recent consume the batchToolbar snippet param and
drop their duplicate filter + dead selectedIds mirror
- Recent: star state via new favoriteIds prop — a star click no longer
rebuilds all N entries
- admin timeAgo >30d fallback uses the cached Intl.DateTimeFormat
- vitest gates in src/lib/components/round11.bench.test.ts

Benchmark-gated (equivalence + BEFORE/AFTER in examples/bench_*, results
and reproduce commands in benches/ROUND6.md):
- CardDAV whole-book REPORT + depth-1 PROPFIND stream through a PG
cursor (stream_contacts_by_book, 500-contact pages) instead of
materialising every vCard twice: 8 000 contacts TTFB 37.4 → 7.6 ms
(4.9x), peak heap 19.0 → 7.0 MiB (2.7x), wall -23%; REPORT and
PROPFIND byte-identical to the buffered writers.
- NC numeric-id chain fully borrowed: get_or_create_file_ids/folder_ids
take &[&str] and return HashMap<Uuid, i64>; batch_resolve_ids callers
(PROPFIND pages, REPORT, trashbin, OCS search) pass id slices and look
up via nc_id_of. 2.006 → 0.006 allocs/child (334x), 1.53x wall per
500-child page. batch_check_favorites binds &[&str] as text[].
- file_blob_read_repository listing SELECTs drop id::text/folder_id::text
server casts: rows decode binary Uuid (16 vs 36 bytes on the wire) and
render once in row_to_file. A/B on 500-row pages: 1.225 → 1.044 ms
mean (1.17x), p95 1.686 → 1.345 (bench_uuid_text_cast; single-row,
param and min() sites left as-is deliberately).
- IncrementalHasher::finalize_hex renders through common::fmt::hex_lower
instead of one format! per digest byte: 18 → 1 (md5) / 35 → 1 (sha256)
allocs per chunk finalize, 14-15x wall.
- Share landing overlaps the access-count UPDATE with the unlock fetch
via tokio::join! (one round-trip off every public link hit).
- REJECTED by benchmark and reverted: try_join_all fan-out of the
batch-favorites authz pre-check — 42.6 → 56.4 ms cold, 0.15 → 0.23 ms
warm against local-socket PG (bench_favorites_authz kept as evidence).

Round 3 of benchmark-gated optimizations (benches/ROUND3.md; every change
gated by a before/after benchmark — an AFTER that did not beat its BEFORE
was to be rolled back; none needed it. Equivalence gates assert identical
row sequences / byte-identical output on every behavior-preserving rewrite):
DB hot paths (local PG16, EXPLAIN-verified):
- Web-UI listing (list_resources_paged): cursor pushed INSIDE the
folders/files UNION-ALL branches as sargable row-value comparisons with
per-branch ORDER/LIMIT + two partial expression indexes
(folder_id, LOWER(name), id). 20k-entry folder: 26.6 -> 1.3 ms/page
(19.5x); other sort modes at parity or better. New migration
20260918000000. [benches/LISTING-KEYSET.md section in ROUND3]
- Photos timeline (list_media_files): per-drive CROSS JOIN LATERAL top-N
on the timeline index, joins moved above the top-N. 50k-photo library:
97.4 -> 1.6 ms/page (55.7x). The old "LIMIT stops the scan early"
comment was refuted by EXPLAIN.
- PROPFIND sub-folders (both DAV surfaces): keyset list_folders_batch off
idx_folders_unique_name replaces COUNT(*) OVER() + LIMIT/OFFSET
(5k dirs: 79.7 -> 17.9 ms full walk, 4.5x).
Concurrency:
- Basic-auth cache single-flight (moka try_get_with): 8 concurrent DAV
connections at TTL expiry paid 8 Argon2id runs (2.6 s CPU + 8x64 MiB);
now 1 (300 ms). Failed verifications remain uncached.
- CachedBlobBackend per-hash single-flight + unique tmp names: 16
concurrent cold readers = 16 full remote downloads racing truncating
writes on ONE deterministic .tmp (corruptible cache); now 1 download
(16x less egress, 2.8x wall on a shared link) and torn files can never
be renamed into the cache.
I/O and allocations:
- Chunk-assembly reads 64K -> 512K buffers (2.3x, 8x fewer syscalls);
chunk-spool writes via BufWriter 512K (5.6x, 32x fewer syscalls).
- S3/Azure put_blob_from_bytes_unsynced overrides: dedup settle no longer
pays a HEAD probe per new chunk (2 RTT -> 1, 1.8x); Azure stops copying
every chunk (Bytes -> Body, -0.44 ms - 4 MiB alloc per 4 MiB chunk).
- Entity->DTO mapping: Arc<str> interning of closed-set display fields +
common MIMEs, 1-alloc etag/size formatting, FolderDto moves instead of
clones. File row: 11 -> 4 allocs; folder row: 11.8 -> 1 (2.1x faster).
- CardDAV REPORT: deleted dead per-contact vCard pre-generation and the
O(N^2) uid scan whose result was discarded (5k contacts: 55.7 -> 5.7 ms,
9.8x); byte-identical XML asserted.
- Search-results cache: byte weigher + 32 MiB budget
(OXICLOUD_SEARCH_CACHE_MAX_BYTES) replaces the 1000-ENTRY cap that let
~300 MiB of enriched rows sit in RSS; read latency parity.
- Dropped aws-config + aws-smithy-types (zero references; -82 dep-graph
nodes, three SDK stacks gone from every build). tokio "process" is now
an explicit feature (was enabled transitively by aws-config).
Frontend:
- Cached Intl.DateTimeFormat keyed by (locale, options) in formatDate and
4 sibling callsites: 20k dates 2612 -> 51 ms (51.6x); vitest gate
asserts output identity across locales and a 3x floor.
Validation: cargo fmt + clippy --all-features --all-targets -D warnings
clean; 518 unit + 548 integration-cfg tests green; new-shape endpoints
smoke-tested end-to-end over HTTP (all 5 listing sort modes with cursor
walks, WebDAV PROPFIND Depth-1, photos timeline, Basic-auth DAV login);
frontend npm run check clean, new vitest gates green.

but returns an explicit 403 forbidden is subject try a forbidden action on a resourse it can read
regarding performance, the role is already in cache for the second call with read perm
Round 2 of benchmark-gated optimizations (benches/ROUND2.md; every change
gated by a before/after in examples/bench_round2.rs — an AFTER that did
not beat its BEFORE was to be rolled back; none needed it):
- Range requests (REST/DAV/shares) answered from the moka content cache
for sub-10MB files: PG resolve + open/seek/read -> Bytes::slice.
256KiB seeks: 1,730/s -> 3.7M/s (p50 552us -> 0.15us).
- Streaming folder/share ZIPs via tokio duplex: TTFB no longer scales
with archive size (326ms -> 0.4ms on 192MiB corpus; total also faster).
Content-Length dropped (size unknown up front).
- NC chunked-upload per-PUT gate: O(k) directory scan+stat -> in-RAM
per-session counter (lazy rebuild on cold start). 1,000-chunk upload
gate cost: 33.1s -> 0.09s cumulative.
- Delta download + commit-verify now use the CDC path's
buffered(read_prefetch) read-ahead: 64-chunk drain at 5ms open
latency 440ms -> 51ms; order preserved.
- CDC ingest settles batches on a spawned task (depth-1 pipeline) so
the source stream keeps flowing during PG pin + backend writes;
rollback ledger shared + lock-serialized so compensation stays exact
on cancellation. 512MiB paced ingest: 60-69 -> 74-75 MB/s.
OXICLOUD_INGEST_OVERLAP=0 restores inline settling (ops/bench hatch).
- Frontend: instant-upload BLAKE3 hashing moved off the main thread to
a bounded Web Worker pool (File handles by reference); vitest gate
asserts the pool beats sequential (first gate draft posting buffers
was 2.6x slower and was rewritten — copies dominated).
Validation: cargo fmt + clippy -D warnings clean; 514 unit + 544
integration tests green; 270 frontend tests green.

Every change is benchmark-verified (harness + before/after numbers in
benches/, measured on this branch; reproduction commands in each doc):
DAV / sync-client hot paths
- PROPFIND dead-properties: one = ANY($1) query per 500-child page instead
of one sequential query per child, and indexable `=` predicates instead
of IS NOT DISTINCT FROM (seq scans). 2,000-child folder: 1.07-4.54 s of
DB chatter -> 4-6 ms (258-773x). Applied to native + NC PROPFIND and
both NC REPORT handlers. [benches/DEAD-PROPS.md]
- Folder paging: keyset cursor (name > $last) + new partial index
(folder_id, name) replaces LIMIT/OFFSET full-folder rescan per page.
Full 20k-file walk: 1266 ms -> 77 ms (16.5x). New migration
20260917000000. [benches/PROPFIND-PAGING.md]
- NC chroot / default-drive resolution: moka caches (30 s TTL, explicit
invalidation on drive mutations) for find_default_for_user and the
markerless chroot FolderDto. 2 uncached queries + 2 pool checkouts per
NC/WebDAV/WOPI request -> sub-us moka hit (p50 0.7-3.6 ms -> ~1 us).
[benches/CHROOT-CACHE.md]
- Quota: PROPFINDs whose prop list never names a quota prop skip the
2-query resolution entirely (wants_quota()); the remaining lookups read
2 columns instead of the full auth.users row with its <=512 KiB avatar
(11-16x, p50 3.4 ms -> 0.29 ms). Same narrow read now gates every
upload quota check. [benches/QUOTA-PATH.md]
CPU on the request path
- ZIP exports (folder download, share ZIP, batch download): entries whose
MIME says already-compressed (JPEG/MP4/zip/pdf/...) are Stored instead
of Deflate - deflate ran inline on the tokio writer task at ~41 MB/s
for ~0% size gain. Mixed media corpus: 4.31x wall and CPU, archive size
unchanged. Shared predicate in common::mime_detect. [benches/ZIP-MEDIA.md]
- Compression layers: tower-http's default maps to Brotli QUALITY 11
(verified in brotli-8.0.2 source and empirically: 90 ms per 64 KiB JSON
response, 1.3 s per 700 KiB bundle). Both layers pinned to Precise(4):
99x less CPU for ~15% more bytes. SPA assets are now precompressed at
build time (scripts/precompress.mjs, 77% smaller) and served via
ServeDir::precompressed_br/gzip: 2016x less per-request work, and
clients get the better q11 bytes. [benches/STATIC-PRECOMPRESSED.md]
Batched / cached backend paths [benches/NPLUS1-AND-CACHES.md]
- Content-search ReBAC re-verification: new
AuthorizationEngine::check_files_read_batch (default = old loop;
PgAclEngine override batches drive resolution + reuses role cache).
200 sequential point SELECTs per search -> 1-2 queries.
- Batch-ZIP subtree downloads: drop per-file re-authz + per-file Recent
recording (2 writes/file) for subtree entries already authorized at the
root - mirrors the native folder-download path. ~6,000 statements
removed from a 2,000-file archive.
- CDC chunk manifests: immutable by content address, now moka-cached
(weight-bounded 32 MiB, 60 s TTL, positive-only, invalidated on delete)
- removes one manifest query (p50 0.44-4.4 ms) from every stream,
range and full blob read.
- People tab: grouped COUNT + batched cover lookup instead of dragging
every face row with its 2 KiB embedding (10k faces: 30.4 ms & 21 MB ->
3.8 ms & 1.3 KB, 8.1x); merge() is one set-based UPDATE.
[benches/PEOPLE-LIST.md]
- Photos timeline cursor: raw timestamptz comparison instead of
EXTRACT(EPOCH ...) wrapper + IS NULL OR disjunction - cursor is an
index boundary again, deep scroll stops re-scanning skipped rows.
- Public share landing: one atomic UPDATE ... access_count + 1 (was
SELECT + full-row write-back: racy, lost updates, clobbered concurrent
owner edits) - 3 round-trips -> 2 per visit.
- move_to_trash: dead full-entity SELECT feeding a documented no-op
removed from both branches; dead fields dropped from TrashService.
- NFC normalization: is_nfc_quick fast path skips the decompose/recompose
state machine for the ~100% already-NFC case (every row loaded from PG).
Frontend
- Large folders paint after page one (~200 items) via fetchFolderListing's
new onPage hook instead of waiting for every sequential page.
- Tested-and-reverted (kept for the record): cached Intl.Collator for name
sorts - vitest showed it 2x SLOWER than V8's argument-less localeCompare
fast path (5.6 ms vs 12.1 ms / 5k names). Sort order untouched.
New bench harnesses under examples/ (bench feature): zip_media,
dead_props, chroot_cache, quota_path, people_list, propfind_paging,
static_precompress.
