this implements first version (manageable only by admin right now)
routes:
GET /api/groups
List subject groups (paginated). Admin-only.
POST /api/groups
Create a new ReBAC subject group. Admin-only. The name must match the RFC 5321 local-part shape and be globally unique (case-insensitive).
GET /api/groups/search
Search non-virtual groups by name substring. Authenticated only (no admin role required) — backs the share-dialog recipient autocomplete.
GET /api/groups/{id}
Fetch a single group's details. Admin-only.
DELETE /api/groups/{id}
Delete a group. Cascades to `subject_group_members` (FK) and to `access_grants` rows referencing this group as a subject. Admin-only.
PATCH /api/groups/{id}
Update a group's metadata. Admin-only. v1 only persists name renames.
GET /api/groups/{id}/effective-members
List every user transitively reached through this group (members of members of members, etc.). Used by admin / audit tooling. Admin-only.
GET /api/groups/{id}/members
List the *direct* members of a group (one level only). Admin-only.
POST /api/groups/{id}/members
Add a member to a group. Exactly one of `user_id` / `group_id` must be provided. Adding a group-member runs a write-time cycle check and a nesting-depth check (max 8). Admin-only.
DELETE /api/groups/{id}/members/group/{gid}
Remove a nested group-member from a group. Admin-only.
DELETE /api/groups/{id}/members/user/{uid}
Remove a user-member from a group. Admin-only.

* make more coherent lifecycles
* remove specific implementation on different handlers (they do not need to know existence of ThumbnailSerice nor AudioMetadataService)
* reduce risk of orphean objects
* ensure additional services are correctly wired (ex: Thumbnail generation was not covering all upload cases)
* more details on docs/architecture/file-and-blob-lifecycle.md :
```rust
// application/ports/file_lifecycle.rs
pub trait FileLifecycleHook {
fn on_file_created(file_id, blob_hash, content_type, is_new_blob);
fn on_file_updated(file_id, blob_hash, content_type);
fn on_file_copied(file_id, blob_hash, content_type, source_id)
fn on_file_deleted(file_id);
}
// application/ports/blob_lifecycle.rs
pub trait BlobLifecycleHook {
fn on_blob_created(blob_hash, content_type);
fn on_blob_deleted(blob_hash);
}
```
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
Security: session hardening
Refresh token rotation with theft detection (family_id)
- Added family_id column to auth.sessions (migration 20260507000000_session_family.sql) grouping all tokens issued from the same login into a family
- On refresh, the new session inherits the parent's family_id
- If a revoked token is replayed (indicates the token was stolen after rotation), the entire family is immediately invalidated and a warning is logged — forcing re-authentication on all devices
SameSite=Strict on refresh cookie
- Access cookie stays SameSite=Lax (needed for top-level navigation)
- Refresh cookie upgraded to SameSite=Strict — it is only ever used for explicit POST to /api/auth/refresh, never via cross-site navigation
Refresh token TTL: 30 days → 7 days
- With rotation, active sessions auto-renew and effectively never expire
- Inactive sessions expire after 7 days instead of 30, reducing the theft window
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.
After successful POST /api/s/{token}/verify, the server issues a
short-lived signed JWT cookie (oxi_share_unlock_<token>; HttpOnly;
SameSite=Lax; 1h TTL). Subsequent /api/s/{token} and
/api/s/{token}/download requests honour the cookie to bypass the
password gate, so password-protected file downloads work end-to-end.
- New module src/infrastructure/services/share_unlock_cookie.rs:
issue_jwt, verify_jwt, extract_from_cookie_header, build_set_cookie
+ 10 unit tests.
- New ShareService methods issue_unlock_jwt and
get_shared_link_with_unlock; trait method get_shared_link_by_token
delegates to a private fetch_share_resolved with an
allow_password_protected flag.
- access_shared_item, verify_shared_item_password, and
download_shared_file honour the unlock cookie.
Reuses OXICLOUD_JWT_SECRET, no new env var. Auth-token JWTs and
unlock-cookie JWTs cannot be confused: auth requires
username/email/role/jti claims, unlock has only sub/exp/iat.
Cross-share replay rejected via claims.sub == requested_token check.
Decode XML-escaped WOPI discovery action attributes before storing them
so generated editor URLs use real query separators instead of literal
& entities. Add regression coverage for parsed actions and generated
edit URLs.
After the blob_hash dedup change, get_cached_thumbnail with
blob_hash=None (cache-first fast path) only checked moka. External
video thumbnails stored as ext-{file_id}.jpg on disk were not found
after a server restart when moka is empty.
Now checks ext-{file_id}.jpg on disk before falling through to the
blob-hash disk lookup, so video thumbnails survive restarts.
Thumbnails are now keyed by blob_hash on disk so identical files share
a single set of thumbnails (icon/preview/large). For 4000 duplicate
files with the same content, this reduces thumbnail storage from 12,000
files to just 3.
Changes:
- get_thumbnail_path() keys by blob_hash instead of file_id
- get_thumbnail(), get_cached_thumbnail(), generate_all_sizes_background()
accept blob_hash parameter for disk dedup
- generate_all_sizes_background() fast path: if blob-hash thumbnails
already exist on disk, skip image processing entirely and just
populate moka cache for the new file_id
- delete_thumbnails() only invalidates moka cache (shared disk
thumbnails must not be deleted when one file is removed)
- delete_blob_thumbnails() added for GC; garbage_collect() now cleans
up orphaned thumbnail files alongside blob files
- External thumbnails (video frames) stored as ext-{file_id}.jpg
since they are client-generated and not dedup-able
- ThumbnailPort trait updated with blob_hash parameters
- All handler call sites updated (file_handler, preview_handler)
- Tests updated for new signatures
- Move all sync I/O (id3::Tag, mp3_duration) into spawn_blocking via
extract_metadata_blocking() to avoid stalling Tokio worker threads
- Replace fetch_all with streaming .fetch() in reextract_all_audio_metadata
for O(1) memory usage regardless of audio file count
- Consolidate get_duration_secs into extract_metadata_blocking, eliminating
redundant file open (tag was read twice before)
- Replace blocking blake3::hash() with DedupService::hash_file() in
file_upload_service (create_file, update_file). Uses spawn_blocking +
mmap_rayon instead of blocking the Tokio async worker.
- Parallelize thumbnail resize+encode with rayon par_iter() for the 3
sizes (Icon, Preview, Large) inside spawn_blocking.
Replace hardcoded DEFAULT_MAX_CONCURRENT_DECODES=4 with adaptive
max_concurrent_decodes() that uses available_parallelism()/2 (min 2).
Matches the pattern already used in image_transcode_service.
Improves thumbnail throughput on 16+ core servers by 2-4x.
