* 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.
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

Explicitly drop the encoded image buffer after decoding and extracting
EXIF orientation data. This reduces peak memory consumption during
thumbnail generation by the size of the original file.
The encoded data is no longer needed once the image is decoded into
a DynamicImage, but it was being held in memory until the end of the
spawn_blocking scope.
Fixes excessive memory consumption in thumbnail generation.
