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
Drops the boolean is_personal() wrapper in favor of matching
DriveKind::Personal/Shared at the two call sites, matching the
exhaustive-match convention already used for DriveKind elsewhere
(as_str, parse, DriveKindDto::from).
repl user_id by caller has read access in readonly functions
using CALLER_CAN_READ_DRIVE constant
ensure webdav preview is using the permission handler
add `include_in_photo_index` and `include_in_music_index` policies
both true for default personal drive
photo is implemented
music is not yet implemented
Adds the foundation for external file mounts: admin-configured backends
(raw host filesystem in v1; sftp/webdav/… as future provider kinds) surfaced
as a folder inside a user's drive. Mount contents are virtual/live-passthrough
— read straight from the backend, never stored in storage.files — and are a
deliberately separate, limited storage type (no dedup/sharing/trash/search).
The feature is dark by default (OXICLOUD_ENABLE_EXTERNAL_MOUNTS=false).
P1 scope (this PR): data model, the pluggable provider abstraction, and the
read-only REST surface (mount listing + download). Read-write (P2),
WebDAV/NextCloud path resolution (P3), and the admin UI (P4) follow.
Core model
- Mount root = a real storage.folders row; authorization for everything inside
collapses onto that folder UUID (ltree-ancestry grant cascade).
- Children are virtual, addressed by ext:<mount_id>:<base64url(node_id)> where
node_id is provider-owned and opaque to the rest of the system.
- A lock-free (arc-swap) MountRegistry maps mount-root UUID -> provider; a thin
MountRouter::classify() is the single cheap hook handlers call before parsing
an id as a UUID. With no mounts configured it always returns Regular, so
existing code paths are unchanged.
Added
- migrations/20260805000000_external_mounts.sql (storage.external_mounts, kind + config JSONB)
- domain/services/external_mount_id (id envelope + virtual etags)
- application/ports/external_mount_ports (ExternalMountProvider, MountProviderFactory, repo port)
- infrastructure local_fs_mount_provider (tokio::fs, symlink-escape-safe) + factory
- application MountRegistry + MountRouter, pg ExternalMountRepository
- DI wiring (AppState.mount_router), FeaturesConfig.enable_external_mounts
- listing branch (FolderService::list_mount_dir_with_perms + folder_handler) and
download branch (FileRetrievalService stat/open mount methods + file_handler)
Authorization stays in the service layer (authz.require(Resource::Folder(mount_id)));
handlers only classify. Cross-backend operations are out of scope for P1.
Tests: 529 unit tests + 5 testcontainers integration tests (real Postgres 17),
including end-to-end authorization (owner allowed, stranger denied). Line
coverage of the new modules is 84–100% (cargo-llvm-cov). Known gap:
file_handler::download_mount_file (HTTP glue) needs a full-app test (P4).
- permit shared drive creation from oxicloud admin (for now)
- prepare other personal drive creation (Not implemented), need to validate
quota policies and strategy first
- add hurl test to verify permissions
remove create_home_folder() & ensure_home_folder()
now: on_user_created() and on_user_login both() call provision_if_needed()
which calls **create_personal_drive_atomic()**
add a helper to find Personal drive for a user and also it's root directorry
now Drive is purely a metadata
each drive has always a root folder
this model minimize Oxicloud changes, and simplify
the Drive name is simply the folder's root's name
note: owner of Drive has more permission that an owner of the root folder
Phase 2 increment 2:
- domain: Face, Person, BoundingBox, DetectedFace (512-d embeddings).
- ports: FaceAnalyzerPort (detect + embed from raw bytes; decodes internally
so the application layer stays image/ML-crate agnostic) and FaceRepository
(user-scoped face/person persistence).
- DTOs: PersonDto, FaceBoxDto.
- NoopFaceAnalyzer — reports is_ready()==false and returns no faces, so the
whole People pipeline compiles and runs inert until the operator wires a
real ONNX-backed analyzer.

prepare migration of permission to roles
this simplify drastically database (permission are now simply defined in code)
and will permit reuse of the same ReBAC engine to define owners of drives
mapping:
```
Role::Viewer => &[Permission::Read],
Role::Commenter => &[Permission::Read, Permission::Comment],
Role::Contributor => &[Permission::Read, Permission::Create],
Role::Editor => &[
Permission::Read,
Permission::Comment,
Permission::Create,
Permission::Update,
],
Role::Owner => &[
Permission::Read,
Permission::Comment,
Permission::Create,
Permission::Update,
Permission::Share,
Permission::Delete,
Permission::Manage,
],
```
Every upload surface previously wrote each byte to disk twice: the HTTP
body was spooled to a temp file (or assembled from chunk parts), then
mmap-re-read for FastCDC analysis, and finally the new chunks were
written to the blob backend. CDC could not start until the last byte
arrived, so large uploads paid receive + reread + rewrite latency.
The dedup engine now chunks, hashes and settles the stream WHILE it
arrives (fastcdc AsyncStreamCDC + incremental BLAKE3):
- Each batch of distinct chunks is pinned-or-classified by ONE
`UPDATE … RETURNING` (no check-then-bump TOCTOU; pinned chunks can't
be reclaimed mid-upload), and only chunks the store doesn't have are
written — a full dedup hit performs zero content writes.
- Durability before visibility is preserved: one batched fsync sweep,
then one batched INSERT, then the manifest. Identical concurrent
uploads are resolved at the manifest INSERT via ON CONFLICT (the
loser releases its references and becomes a dedup hit).
- A drop guard rolls back pins and surfaces written-but-unregistered
chunks to GC if the request future is cancelled mid-stream.
- MIME sniffing now peeks the first bytes in-flight; client-requested
MD5/SHA-256 checksums are computed by a stream tee — the post-upload
re-read of the assembled file is gone.
All surfaces converge on the new interfaces::upload_ingest helper:
REST multipart, WebDAV PUT, NextCloud PUT, WOPI PutFile, the dedup
endpoint, and both chunked-upload completions (which now stream their
ordered parts straight into the store instead of writing an assembled
file — chunk parts persist until finalize, so completion is genuinely
retryable). The legacy blob re-chunk migration streams from the
backend with no spool file either.
Legacy removed: store_from_file + mmap CDC analysers + temp-path
plumbing through every port (pre_computed_hash, save_file_from_temp,
update_file_content_from_temp), upload_spool + assembled-file
assembly in both chunked services, create_file/update_file byte-slice
variants (no callers), common::temp, the OXICLOUD_UPLOAD_TMPDIR
config, and the memmap2 dependency.
Verified end-to-end against PostgreSQL 16: 8 MB upload (26 chunks),
identical re-upload (dedup hit, zero writes), 3-byte edit re-upload
(26 chunks, 1 written), byte-identical downloads, Range across chunk
boundaries, concurrent identical-upload race (manifest ref 2), and
trash-empty reclaiming exactly the unshared chunk while the shared 25
survive for the edited file. The empty/sub-8KB multipart path found a
post-EOF re-poll panic in the MIME peek (fixed with fuse + regression
test).

A REPORT multiget for a handful of resources previously listed the
whole calendar/address book (every row incl. ical_data/vcard) and
filtered by href in Rust with an O(N×M) substring scan. Large
collections paid full-table latency, RAM and DB CPU on every sync.
- Add find_events_by_ical_uids / get_contacts_by_uids through every
layer (domain repo trait → PG repo → storage port/adapter → use case
→ handler) using one indexed `= ANY($2)` query, mirroring the
existing single-UID lookups.
- Extract UIDs from multiget hrefs with a shared, tested
uid_from_multiget_href helper (percent-decoding, case-insensitive
extension strip, collection hrefs rejected). Exact UID matching also
removes the false positives the old substring filter allowed.
- CalDAV PROPFIND single-event path now uses the existing indexed
get_event_by_ical_uid instead of listing all events.
- Honour the already-documented limit/offset query params on
GET /api/address-books/{id}/contacts: optional ListQuery fields
thread through ContactUseCase::list_contacts to a paginated repo
query. Omitted params keep returning the full book (frontend and
DAV listing/sync paths unchanged).

Every WebDAV / CalDAV / CardDAV request paid one full-row user fetch in
require_internal_user_layer just to read `is_external` (and the NC Basic
Auth middleware repeated it right after its own cache hit). That SELECT
includes the `image` column — a data URI of up to 512 KiB — so a sync
client issuing hundreds of PROPFINDs per minute dragged hundreds of MB
of avatar bytes out of Postgres to evaluate a boolean.
- New `UserFlags { role, is_external, active }` + a repo query selecting
only those three columns (inherent method, mirroring `update_image`).
- `AuthApplicationService::get_user_flags`: moka cache, 30 s TTL,
10k capacity. `change_user_role` / `set_user_active` invalidate
eagerly, so admin changes still apply immediately; anything else is
visible within the TTL — preserving the documented "no token rotation
needed" semantics at a per-request cost of zero DB round-trips when
warm.
- `require_internal_user`, `require_admin_user` and the NC Basic Auth
external check now go through the flags lookup.

StoragePath::join deep-cloned the whole Vec<String> (every segment String)
just to append one element. Take self by value and push in place. All callers
pass owned values except PathService::create_file_path, which holds a borrow
and now clones explicitly — the same copy the old &self join already made.
File::with_name / with_folder / with_size took &self and rebuilt the struct,
cloning every carried-over field (id, mime_type, folder_id, blob_hash, ...).
Consume self and mutate only the fields that change. Behaviour is identical;
the fallible builders now drop the input on Err, which is fine for these
rename/move/resize transforms (all current callers replace the file).
Impact is small in practice — with_folder/with_size have no callers and
with_name is test-only, while the one hot join caller (create_file_path)
must copy segments regardless — but the consuming form is the idiomatic one.
Verified: cargo fmt + clippy --all-features --all-targets -D warnings clean;
domain tests (path_service::, entities::file::) pass — 30 + 6.

TL;DR:
fix duplicate filename via:
```
docker exec <container> migrate-nfc-filenames --dry-run # preview
docker exec <container> migrate-nfc-filenames # execute
```
== issue ==
Last week I uploaded Capture d'écran 2026-06-03 à 20.04.24.png from the web. It synced down to Nextcloud on my Mac. Two minutes later, the Web UI was showing the file twice.
Both rows had:
- the same name
- the same size
- the same content hash
So why two rows? Because to PostgreSQL, the names weren't the same.
Web upload (browser → Postgres):
"é" stored as 1 codepoint (U+00E9) bytes: c3 a9 ← NFC
NiextCloud client (macOS → Postgres):
"é" stored as 2 codepoints (e + U+0301) bytes: 65 cc 81 ← NFD
macOS's APFS keeps filenames in NFD (decomposed); browsers send NFC (composed). Visually é and é are identical. To WHERE name = $1 they're two different keys. Our UNIQUE index on (folder_id, name, user_id) never fired — and the row count quietly drifted every time a Mac user touched an accented
filename.
== The fix is two halves ==
1. No new duplicates — every name-receiving boundary (file upload, NC PUT, rename, MOVE, path lookup) now NFC-normalizes before touching the database. The storage invariant becomes "every stored name is NFC".
2. Clean up existing data — one-shot migrate-nfc-filenames binary walks storage.files, NFC-normalizes any non-NFC row, and resolves the collisions we've accumulated. Same-content duplicates go to trash (recoverable); different-content collisions get renamed with a .duplicate suffix.
== use of the clean up ==
