add /api/folders/{id}/ancestors
this API to iterate parent up to the drive root or the shared folder
this will help UI to build the breadcrumb in 1 API call
and to identify the root element (is it a drive users has access to or
a shared folder ?)
ui: now only 1 API call is now required to build the breadcrumb
- 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).

Two behaviour-preserving allocation cuts (benches/ROUND27.md), each with a
counting-allocator BEFORE/AFTER gate that rolls back if AFTER does not allocate
fewer than BEFORE:
- H1 NextCloud PROPFIND: the streaming page loops built oc:id as a fresh String
per child (format_oc_id -> format!("{:08}{}", id, instance)). Add
format_oc_id_into(&mut buf, id, svc) and compute into one oc_buf reused across
the page (next to the existing href buffer) — 1 String/row -> 0. 998->0
per-row allocs on a 500-row page, 2.16x wall. The write fns still take
Option<&str>, so no signature change; oc:id bytes identical. Scoped to the two
PROPFIND page loops (the hot directory-listing path); REPORT/trashbin deferred.
- P2 contact create/update: bind sqlx::types::Json(&dtos) (Encode runs to_writer
straight into the JSONB buffer) instead of serde_json::to_value(&dtos) + bind,
which built a throwaway Value DOM per JSONB column. Write-side twin of ROUND23
J1. 21->2 allocs, 4.68x wall for a 3-entry column. Behaviour-preserving:
to_value sorts keys and direct serialize keeps struct order, but Postgres
normalizes JSONB key order so the stored value is identical (verified via psql:
'{...alpha...}'::jsonb = '{...struct...}'::jsonb -> t), and reads decode by
field name; the etag comes from the domain entity, not the stored JSONB.
Adds bench_round27_micro. Verified: cargo fmt clean, cargo clippy --features
bench -D warnings clean (real exit), cargo test --lib --features bench = 529
passed / 0 failed.

Three benchmark-gated optimizations from the ROUND25 backlog (benches/ROUND26.md),
each with a BEFORE/AFTER gate that rolls back if AFTER does not beat BEFORE:
- P1 drive_pg_repository policy reads: decode d.policies through
sqlx::types::Json<DrivePolicies> (one from_slice over the raw JSONB bytes)
instead of a throwaway serde_json::Value DOM + DrivePolicies::from_value —
6 -> 0 allocs/read, 2.77x wall. A shared policies_from_row helper preserves
the lenient unwrap_or_default fallback (malformed bag -> all-false).
- D1 CachedBlobBackend: pre-create the 256 {00..ff} shard dirs at initialize()
(mirroring LocalBlobBackend, reusing HEX_PREFIXES) and drop the redundant
per-write create_dir_all on already-existing shards — ~45us + a blocking-pool
dispatch removed per cache write on cached-remote deployments.
- G1 delta-upload have/need hash sets (distinct_hashes, authorize_chunk_download):
SipHash -> foldhash::quality::RandomState — a fast hasher that stays
DoS-resistant via a per-instance random seed, the required property for the
attacker-controlled 64-hex client hashes — 2.37x wall on a 40k-hash
negotiation. foldhash was already in the lockfile transitively (hashbrown).
Tested and REVERTED (kept as-is): moving the moka eviction unlink off the reactor
via spawn_blocking. The benchmark refuted it — on the local cache dir the
spawn_blocking dispatch (~20us) costs more than the inline unlink (~7us) it would
replace. See ROUND26.md §D2.
Adds bench_round26_{micro,diskio,hasher} (counting allocator / async wall / wall).
Verified: cargo fmt clean, cargo clippy --features bench -D warnings clean,
cargo test --lib --features bench = 529 passed / 0 failed.

Five benchmark-gated optimizations from a fresh six-way audit (benches/ROUND25.md),
each with a BEFORE/AFTER gate that rolls back if AFTER does not beat BEFORE:
- M1 EncryptedBlobBackend::decrypt_bytes: replace split_off (a fresh Vec + full
ciphertext memcpy on every decrypted chunk, contradicting its own "in place"
doc) with in-place detached decrypt + a zero-copy Bytes::slice past the nonce.
Peak RAM per read drops from ~2x to ~1x the payload (-262KB/op at 256KiB;
scales with blob size). Plaintext byte-identical; tamper/wrong-key tests pass.
- M2 delta commit: move-unzip the owned chunk list instead of a third
per-occurrence hash clone (-4000 allocs on a 4000-chunk commit).
- M3 folder ZIP download: drop the dead Query<HashMap> extractor it never read
(byte-identical response; 5->0 allocs/request).
- Q1 public-playlist listing: fold the per-playlist COUNT(*) N+1 into one
LEFT JOIN ... GROUP BY via a new inherent repo method (101 -> 1 round-trips,
36x wall on a 100-playlist page).
- Q2 contact REST listings (paginated/search/by-group): stop over-fetching the
multi-KB vcard TEXT the ContactDto discards, via a shared lite row mapper and
narrowed SELECTs (6.4x wall on 1000 contacts with 8KiB vcards). The whole-book
vCard export and CardDAV sync paths keep the column.
Adds bench_round25_micro (counting allocator tracking count+bytes) and
bench_round25_queries (live Postgres), both with equivalence gates and a
rollback exit(1). Verified: cargo fmt clean, cargo clippy -D warnings clean,
cargo test --lib --features bench = 529 passed / 0 failed.

Benchmark-gated, same rule as ROUND2-22: BEFORE/AFTER with a value-equivalence
gate and rollback-on-regression. Two harnesses — bench_round23_micro (no
Postgres; deterministic allocation gate) and bench_round23_queries (live
Postgres; p50 latency + strict equivalence gate against seeded fixtures). See
benches/ROUND23.md.
- J1: contact_pg_repository::row_to_contact (+ the inlined contact_group sibling)
decode the 3 JSONB columns via sqlx::types::Json<T> (one from_slice pass)
instead of row.get::<serde_json::Value> + from_value (a throwaway Value DOM
per column, walked a second time). Per contact row of every list / multiget /
CardDAV sync. Micro 84 -> 33 allocs/op (2.15x); PG 3794 -> 2360 ns/contact
(1.61x) on 500 real rows.
- J2: DrivePolicies::from_value deserializes straight from the borrow
(T::deserialize(&Value)) instead of from_value(value.clone()) — dropping the
full-DOM clone on every drive-policy read (move/copy, share, grant); one-line
body change, all 7 callers unchanged. Micro 5 -> 0 allocs/op (11.51x).
- P1: get_user_profile overlaps the two independent caller+target reads with
tokio::join! (self-case still a single fetch; caller-error precedence
preserved via caller_res? first) instead of two serial round-trips. PG
577 -> 312 us/call (1.85x).
- G1: subject_group remove_member computes the child's transitive-user recursive
CTE once and reuses it for both the would-empty pre-check and the cache
invalidation, instead of running the identical CTE twice (the edge delete is
above the child, so its descendants can't change). PG 829 -> 412 us/removal
(2.01x).
- U1: dedup_service (store_loose_chunks final registration + the ingest
run_rollback) reshapes the owned, dead-after Vec<(String,i64)> via
into_iter().unzip() instead of cloning every 64-byte hash for the
sync_blobs(&[String]) + UNNEST bind. Micro 256 -> 0 hash clones.
Verified: cargo clippy --features bench --all-targets -D warnings clean, cargo
fmt --all --check clean, cargo test --lib --features bench = 529 passed / 0
failed. The PG benches run against a local PostgreSQL 16 (schema applied from
migrations/); every equivalence gate passes.
The download_zip per-item N+1 (the audit's highest raw-latency candidate) is
deferred to a dedicated pass: its fix moves the sole authorization inside the
stream call, so it needs an AuthZ-ordering + anti-enumeration proof, not a perf
banner.

Round 21 of the benchmark-gated perf sweep. Six behaviour-preserving,
allocation-reducing changes, each with a BEFORE/AFTER counting-allocator
section in examples/bench_round21_micro.rs and a byte/-value equivalence
gate; all six pass their deterministic alloc gate (a non-winning AFTER
exits 1 = rollback).
- R1: pre-size the 16 CalDAV/CardDAV row-mapper Vecs (+1 HashMap) with
Vec::with_capacity(rows.len()) — the ROUND20 §I1 file-side pattern
extended to the calendar/contact repos it deferred. 7 → 1 allocs/op.
- R2: settle_batch binds a borrowed Vec<&str> instead of cloning every
chunk hash into a Vec<String> (sqlx encodes &[&str] as text[]
identically; favorites_pg_repository.rs:271 precedent). 33 → 1 allocs/op,
39x wall.
- R3: store_loose_chunks keys its intra-request dedup set on the raw
[u8;32] BLAKE3 digest and moves the hex on a duplicate (the ROUND17 §D2
pattern applied to the delta-upload sibling). 401 → 209 allocs/op.
- R4: CardDAV getetag emits borrowed pre-escaped " quotes via a shared
write_quoted_etag helper (ROUND20 §C1 pattern, all 4 CardDAV etag sites).
3 → 0 allocs/op.
- R5: BDAY stamped via the new fmt::compact_date stack renderer instead of
chrono's strftime interpreter (chrono fallback out of the 4-digit-year
range; byte-identical, unit-tested vs chrono). 2 → 0 allocs/op, 10.5x wall.
- R6: NC trashbin folder content-type via Cow::Borrowed instead of
.to_string() on the constant (ROUND16 §M1 pattern). 1 → 0 allocs/op.
See benches/ROUND21.md for the full write-up and the deferred-items list
(HeaderMap-clone hot handlers, Query→typed-struct, WebDAV dead-props
HashSet, and others surfaced by the audit that want their own validated
pass). Validated: cargo fmt, cargo clippy --features bench --all-targets
-D warnings, cargo test --lib --features test_utils (529 passed).

Benchmark-gated (benches/ROUND20.md), same rule as rounds 2-19: every change
ships with a BEFORE/AFTER counting-allocator micro-benchmark and a byte-value
equivalence gate; a non-winning AFTER is rolled back (never applied). The
rollback rule is encoded in the harness (GATE FAIL exit). All 8 sections pass.
Reproduce: cargo run --release --features bench --example bench_round20_micro
- A1 CalendarEvent iCal parse: replace the throwaway per-property
HashMap<String,Vec<String>> (DTSTART/DTEND/RECURRENCE-ID) with a direct
VALUE=DATE scan; prop_with_params kept #[cfg(test)] (6->2 allocs/event, 4.2x)
- A2 UserDto::from: add User::into_parts and MOVE image (<=512 KiB data URI)
+ ui_preferences JSON instead of cloning on every /api/auth/me (27->14 allocs)
- A3 parse_vcard: drop the per-line to_ascii_uppercase copy + the lines Vec;
promote ascii_ci_contains to common::text and share it (8->1 allocs/contact)
- A4 Calendar/AddressBook DTO: into_parts move incl. custom_properties map (18->10)
- I1 file-listing repos: collect::<Result<Vec>>() size-hints to 0 and grows from
capacity 0; pre-size with Vec::with_capacity (8->1 container reallocs, 4 sites)
- I4 plaintext_stream: lazy emit iterator instead of eager Vec collect (43x wall)
- C1 NC write_etag_element: borrowed pre-escaped quote events, no owned quoted
String/escape re-alloc; byte-identical output (3->0 allocs/PROPFIND row)
- C3 NC favorites REPORT: map.remove() move instead of get().clone() (~7 allocs/fav)
Deferred (documented in ROUND20.md): NC oc:id/trashbin buffer reuse, I1 sibling
CardDAV/CalDAV listing paths, Contact JSONB Json<Vec<_>> decode, dedup
settle_batch &str bind, and a fast DoS-resistant hasher for hot trusted-key maps
(needs a dependency decision).

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.

- benches/ROUND11.md: final BEFORE/AFTER numbers for all 21 micro
sections, the 5 query sections, the 4 log-writer arms, the SPA gates,
and the two cross-round regression guards (bench_row_path 2.52x,
bench_dto_map — both byte-identical)
- ROLLBACK (gate-caught): min(fm.file_id)::text geo-cluster cast —
PostgreSQL has no min(uuid) aggregate; the bench section now reproduces
the rejection and the per-row-cast original stays
- REJECTED (bench-measured): tracing-appender non-blocking writer —
slower than sync on fast sinks (1.41M vs 0.99M ev/s, worse tail) and
the slow-sink drain gate showed shutdown tail-loss risk for the audit
channel; dep moved to dev-dependencies (harness only)
- RateLimiter final form: lock-free get + insert (8.0 → 6.0 allocs, wall
neutral; and_upsert_with variant rejected at 2 365 ns)
- fix: TrashedItemParts insertion had stolen TrashedItem's derive line
(caught by clippy --all-targets)
- grant_role enum values corrected in the queries bench
Validation: cargo fmt + clippy --all-features --all-targets -D warnings
clean; cargo test --workspace 524 passed / 0 failed; frontend npm run
check 0 errors + vitest 306 passed (1 pre-existing round-7 wall-clock

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

- 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

- /status.php and /openapi.json memoized into OnceLock<Bytes> (openapi

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).

this fix https://github.com/AtalayaLabs/OxiCloud/issues/607
which was introduced by commit 12dc648cff
when a user rename a root folder, this invalidate the cache
still some UX effect displaying phantom drive is grant is revoked,
cache is 30s of TTL so this UX glitch is acceptable
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.

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.

- add resource kind filter (file, folder, drive) in shared section (localStorage stored)
- add user preferences serverside store
- add client side dotfile filter (show/hide dotfiles) (user perf stored, default: dotfiles are shown)
for security trashed dotfile are always displayed
protection added: if a folder has only hidden items, a notification invite user to display it
if a user rename or create a hidden item, a notification tells it to user

What step 5 is actually doing
Goal: stop writing to storage.files.user_id / storage.folders.user_id on new INSERTs. This is a prerequisite for step 6 (dropping the column entirely). The column has existed since the pre-D0 single-owner era; every read that used to key on it has already been migrated to drive-membership grants over the last N days.
What has to change together for this to be safe:
