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).

Files uploaded before chunk_manifests landed (20260414000000) are stored
as ONE whole-file blob with no manifest. Every legacy fallback in
DedupService exists to serve them, and the cost concentrates on Range
reads: with encryption enabled, seeking inside a legacy video decrypts
the ENTIRE blob (AES-GCM is all-or-nothing), where a CDC file decrypts
only the overlapping <=1 MiB chunks.
This adds a one-time, idempotent background migration (spawned from the
composition root after dedup init, maintenance pool) that converts each
legacy blob into a regular CDC file, indistinguishable from a native
upload:
1. Spool the blob through the normal read path (decrypts when
encryption is on) to a per-attempt-unique temp file, verifying
BLAKE3 == hash; sizes come from the verified spool, never from the
legacy storage.blobs.size column (the manifest's total_size drives
Range arithmetic).
2. CDC-chunk + store chunks via the existing store_chunks (one
manifest reference per distinct chunk).
3. One short accounting TX with the blob row locked: manifest INSERT
with ref_count = N current file references, blob ref_count -= N,
row deleted only at exactly 0 - so single-chunk files (chunk hash
== file hash) keep the physical blob, which IS the chunk; only
bookkeeping moves, no bytes are rewritten.
4. Physical whole-file blob deleted only when its row dropped.
Races lean on the row lock: a concurrent identical upload landing a
legacy reference after commit keeps the blob row alive and that file
readable via the fallback (bounded space leak, never data loss); a
crash between chunk store and the TX over-counts one file's chunk refs
(also a bounded leak). Corrupt blobs (content != hash) are logged,
counted, excluded from the sweep and left untouched, with a hard cap
before aborting.
Per-hash failures never block the sweep; manifests are the resumability
marker, so a restart continues where it left off. The legacy read/write
fallbacks stay in place as the safety net while a deployment converges;
they can be deleted once fleets report "legacy re-chunk: nothing to do".
Opt-out via OXICLOUD_LEGACY_RECHUNK=false (documented in example.env)
for metered remote backends where the one-time re-read should be
scheduled deliberately.
Covered by five integration tests against real PostgreSQL (multi-chunk
accounting + Range across a chunk boundary, single-chunk physical-blob
preservation, corrupt-blob isolation, empty blob, and the full
encrypted-backend roundtrip); they run concurrently, which also
exercises the cross-sweep race handling.

The read repository's hash_cache assumed blob hashes were immutable
per file_id, but update_file_content_from_temp remaps the SAME row to
a new hash via swap_blob_hash. After a WebDAV/NC PUT overwrite,
streaming downloads (>=10 MB tier, Range requests, video playback)
kept resolving the OLD blob for the 30 s TTI window — and because
every read refreshes the TTI, a polling client could pin the stale
mapping indefinitely, eventually turning into 500s once the old
blob's refcount hit zero and GC removed it.
The write repository now holds a shared handle to the same moka cache
(clones share storage) and invalidates the entry right after every
content swap and hard delete commits — covering every present and
future caller of the write port rather than one service path. Stale
doc comments claiming the mapping was immutable (and SHA-256) fixed.

GET /api/auth/me ran a synchronous O(N) SUM(size) over all the user's
files plus an unconditional UPDATE of auth.users on every call — one of
the most frequently hit endpoints — adding per-request latency, DB write
load, dead tuples and WAL even when nothing changed.
- /api/auth/me now serves the cached storage_used_bytes column instead of
recomputing it inline.
- New StorageUsageService::start_reconciliation_job runs a periodic sweep
on the maintenance pool that keeps the cached value current for every
mutation (uploads, deletes, trash), so freshness no longer depends on
hitting /me. Interval via OXICLOUD_STORAGE_USAGE_RECONCILE_SECS (default
600s, floored at 30s; first sweep deferred one interval to avoid boot load).
- update_storage_usage only writes when the value actually changes
(IS DISTINCT FROM), so the sweep produces no dead tuple / WAL on no-ops.
- New covering partial index idx_files_user_size_active makes the usage
SUM an index-only scan instead of a heap scan over all the user's files.
Also collapse the same pre-existing clippy collapsible_else_if in
carddav_handler that blocks the -D warnings gate on this base.

Large uploads (e.g. ~800 MB ISOs) could OOMKill the process, even on
dedup hits, due to three separate full-file-in-memory paths:
- NextCloud PUT (/remote.php/dav) buffered the entire body in RAM via
body::to_bytes before any dedup logic, then re-wrote and re-hashed it.
Now streams the body to a temp file with incremental BLAKE3 and goes
through update_file_streaming (shared spool helper with the native
WebDAV PUT handler); peak heap is ~one HTTP frame regardless of size.
- DedupService::store_chunks materialized every new chunk's data in a Vec
before uploading. Now reads each new chunk by positioned I/O
(read_exact_at, off the runtime via spawn_blocking) just before its
upload; peak heap bounded to ~CHUNK_UPLOAD_CONCURRENCY x CDC_MAX_CHUNK.
- The upload spool used the OS temp dir, often tmpfs/RAM in containers
where its page-cache counts against the cgroup memory limit. Add
OXICLOUD_UPLOAD_TMPDIR to point the spool at real disk.
Also collapse a pre-existing clippy collapsible_else_if in carddav_handler.

schema migration, User entity additions, and three defense-in-depth gaps closed, with all 280 unit tests and 13 Hurl files green
infrastructure (lettre + EmailSender port).
- Migration migrations/20260612000003_users_username_email_login.sql — adds nullable given_name/family_name columns to auth.users.
- User entity (src/domain/entities/user.rs) — has_login_credential() placeholder-check encapsulation, set_username revalidating setter, given/family-name fields + getters/setters, validate_username widened 32→254 and now accepts email shape.
from_data_full extended with two new params; all 7 callsites in user_pg_repository.rs updated.
- Schema-side legacy guards (src/application/services/auth_application_service.rs) — bumped the duplicated 32-char check in setup_create_admin and admin_create_user to 254 to match.
- Gap #1 (subject_group_service.rs) — add_member now rejects external candidates with an audit-logged AccessDenied. Service gained an Arc<UserPgRepository> field, wired through DI. New integration test test_external_user_cannot_be_added_as_member.
- Gap #2 (user_repository.rs + auth_ports.rs + user_pg_repository.rs) — list_users/search_users gained an include_external: bool param defaulting effectively to false everywhere internal-user-facing. auth_application_service exposes a new
list_users_including_external for the admin surface.
- Gap #3 (pg_acl_engine.rs) — expand_user now SELECTs is_external and skips INTERNAL_GROUP_ID for externals; defaults to is_external=true on missing user to fail closed.
prepare identity service for external users, support of:
- magic_link (url challenge via email)
- self issued oidc (eventually social login)
- open cloud mesh
- AuthzCacheLifecycleHook — invalidates the user_groups_cache Moka entry on logout/delete.
- SessionRevocationLifecycleHook — explicit per-session firing of on_user_logout (currently per-call); session revocation inside the user-delete transaction.
- DeletionMode-driven policy in HomeFolderLifecycleHook::on_user_deleted (trash vs hard-delete based on AdminDelete / GdprPurge).
- Refactor delete_user_admin to expose a transaction handle so on_user_deleted can abort atomically.

Bug 1 & 2 (webdav_handler.rs handle_put() update branch):
- After a successful file update via WebDAV PUT, if the content type is a supported image:
a. delete_thumbnails(file_id) — evicts the stale moka cache entry
b. Spawns a background task to read the new blob bytes and call generate_all_sizes_background_from_bytes
Bug 3 & 4 (dedup_service.rs):
- Added thumbnail_service: Option<Arc<ThumbnailService>> field with a with_thumbnail_service() builder
- In remove_legacy_reference(): calls delete_blob_thumbnails(hash) when ref_count hits 0
- In remove_manifest_reference(): calls delete_blob_thumbnails(file_hash) when manifest's last ref is dropped
- Wired in di.rs — the thumbnail service is created before dedup service so the ordering works cleanly
Five new public endpoints under /api/s/{token}/...:
GET /contents
GET /contents/{folder_id}
GET /file/{file_id}
GET /zip
GET /zip/{folder_id}
All honour the unlock cookie from /verify, so password-protected
folder shares work end-to-end.
Folder/file IDs are validated against the share subtree via a single
ltree containment query (O(log N) on the existing GiST index).
Out-of-scope IDs return 404.
download_shared_file refactored to a Range/304/206/416-aware
serve_share_file helper, shared with the new /file/{file_id}
endpoint. content_disposition extracted from FileHandler so RFC 5987
formatting is identical across auth and share download paths.
Resolves conflict between main and PR #229 by applying timeout support
on top of main's drop(data) memory optimization. Changes:
- Add thumbnail_generation_ms to TimeoutConfig (default 30s)
- Add generation_timeout field to ThumbnailService
- Wrap spawn_blocking in tokio::time::timeout to prevent hanging
- Update DI to pass timeout from config
- Update tests to provide timeout parameter

When moving a file to a folder, verify that the caller owns the target
folder. Without this check, a file could be moved to another user's
folder, causing the file to "disappear" from the original user's view
since file listings filter by user_id.
- Add folder_repo to FileManagementService
- Add verify_target_folder_owner() method
- Call it in move_file_owned() before moving
Extract EXIF orientation, GPS coordinates, camera info, and timestamps
from uploaded images using kamadak-exif. Store metadata in a new
file_metadata PG table. Apply EXIF orientation to thumbnail generation
so images display correctly. Add /api/files/{id}/metadata endpoint.
- JWT secret auto-generates and persists to <STORAGE_PATH>/.jwt_secret
- Remove setup token: first admin setup is open until system initialized
- Fix schema.sql: move CREATE EXTENSION pg_trgm/ltree to top
- Update login UI and auth.js to remove setup token fields
Implement a complete Nextcloud client compatibility layer so that
Nextcloud desktop/mobile sync clients can connect to OxiCloud.
Key additions:
- Login Flow v2 (device auth) with OIDC bridge support
- WebDAV handler compatible with Nextcloud clients (PROPFIND, GET,
PUT, DELETE, MKCOL, MOVE, COPY, HEAD, PROPPATCH)
- OCS API endpoints (user info, capabilities, notifications stubs,
sharees, unified search)
- Basic Auth middleware with app password verification, account
lockout integration, and blake3-keyed auth cache
- App password management: create, list, revoke via both native
API (JWT-authenticated profile page) and Nextcloud OCS endpoints
- Nextcloud file ID mapping (oc:fileid) with persistent DB storage
- Chunked upload support (Nextcloud v2 chunking protocol)
- Trashbin WebDAV interface
- Avatar (SVG placeholder) and preview (redirect) handlers
- User profile page with app password management UI
- URL user validation on all DAV routes (403 on mismatch)
- Database schema for app_passwords and nextcloud_object_ids tables
All services are behind a `nextcloud.enabled` config flag and
cleanly separated under src/interfaces/nextcloud/.
