Edouard Vanbelle 4e36de49eb feat(uploads): add OXICLOUD_CHUNK_DIR + documentation for admins
explain OXICLOUD_CHUNK_DIR and OXICLOUD_UPLOAD_TMPDIR
    and also the OXICLOUD_CHUNK_MAX_BYTES & OXICLOUD_UPLOAD_TMPDIR
    to help administratorrs to defined correctly their storage architecture

Edouard Vanbelle 2843b3351b feat(blake digest): ensure digest is done on same passe as the write of chunks
purpose: avoid current scheme:
        1. write to disk
        2. reopen file to read data and digest it

    now: digest is done while writing data to disk

    all other implementation than Nextcloud are corrrect

Edouard Vanbelle abac074fe5 feat(fssync): ensure fs sync once upload is recomposed 2026-06-09 09:55:27 +02:00
Edouard Vanbelle 41aad26702 feat(upload): cover chunk upload + add support of different digest hash
Prefer stream storage rather using buffered (in memory)

  note: on many unix like tmpfs are in-memory, sungle PUT are sized limited

Edouard Vanbelle 5e638691ad security(upload): cap upload size to prevent memody/disk consumption
add OXICLOUD_CHUNK_MAX_BYTES which correspond to the max upload chunk allowed
    (differs from OXICLOUD_MAX_UPLOAD_SIZE which is the max total size of a file)
    hurl test validate the change

    Streams the request body straight to the chunk file with peak heap of
    ~one HTTP frame, regardless of chunk size or the configured cap. The
    `storage.chunk_max_bytes` config (env `OXICLOUD_CHUNK_MAX_BYTES`,
    default 100 MB) bounds a single PUT — separate from `max_upload_size`
    which governs whole-file uploads. Without this separation, a client
    could submit a chunk up to the whole-file cap (10 GB default) and
    monopolise server memory.

Edouard Vanbelle 3fc0a272ca fix(nextcloud): resume (PROPFIND) on upload chunk
PROPFIND on upload chunk is necessary for application to resume the upload
    it is used at least by Nextcloud Android app

    issue has been raised via #415

    unable to test, so I am using a playbook in test/webdav to simulate a
    PROPIND on remote.php/dav/uploads/{user}/{session}

DioCrafts 061306cc84 fix(upload): stream WebDAV/NextCloud PUT to disk to prevent OOM on large files
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.

Edouard Vanbelle 5fab0532dc feat(user): add given_name/family_name auth.users
reflect OIDC
  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.

Edouard Vanbelle 6a6f070106 feat(userLifecycle): plug actions to on_user_logout and on_user_deleted
- 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.

Edouard Vanbelle 09985f8a95 feat(group): 1st implementation of Groups
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.

Edouard Vanbelle 78cb37b311 feat: check thumbnail cleanup on files deletion + correct ref counter 2026-05-13 15:55:38 +02:00
Edouard Vanbelle 9f57776ec9 bugfix/thumbnails on update
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

abnvle 3bc5c0873b fix(share): password-protected downloads via signed unlock cookie
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.

- Replace whole-file SHA-256 dedup with FastCDC 2020 content-defined chunking
  (min 64KB, avg 256KB, max 1MB) + BLAKE3 hashing
- Add chunk_manifests table (file_hash → chunk_hashes[] + chunk_sizes[])
- Add put_blob_from_bytes to BlobStorageBackend trait (all 7 backends)
- 3-phase store_chunks pipeline:
  Phase 0: batch-check existing chunks (single PG query)
  Phase 1: selective disk read (skip existing chunks entirely)
  Phase 2: parallel upload with buffer_unordered(8)
- CDC-aware read_blob_stream and read_blob_range_stream with legacy fallback
- Transactional manifest + chunk ref-count cascade on remove_reference
- 12 CDC tests (determinism, reassembly, contiguity, sub-file dedup, etc.)
- Update deduplication.md to reflect new architecture

Diocrafts cd3733b459 feat: pluggable storage backends (S3, Azure, local) with admin UI
Implement 4-phase external storage backends architecture:

Phase 1 - Foundation:
- BlobStorageBackend trait (application/ports/blob_storage_ports.rs)
- LocalBlobBackend: extracted all tokio::fs ops from DedupService
- S3BlobBackend: AWS SDK with custom endpoint support (MinIO, R2, B2)
- DedupService refactored to use Arc<dyn BlobStorageBackend>

Phase 2 - Admin Panel:
- StorageSettingsService with DB persistence + env override
- Storage tab in admin panel (backend selector, S3 form, provider presets)
- GET/PUT/POST endpoints for storage settings + connection test
- i18n keys (en/es) and BEM CSS

Phase 3 - Migration:
- MigrationBlobBackend decorator (dual-read: target-first + source fallback)
- Background migration job with parallel transfers + progress tracking
- Migration UI (progress bar, ETA, pause/resume/verify/complete)
- 6 admin API endpoints for migration lifecycle

Phase 4 - Enterprise Extras:
- CachedBlobBackend: LRU disk cache for remote backends
- EncryptedBlobBackend: AES-256-GCM at-rest encryption
- AzureBlobBackend: Azure Blob Storage support
- RetryBlobBackend: exponential backoff for transient errors
- Decorator composition in DI: retry → encryption → cache

All 223 tests passing, clippy clean, fmt verified.

Diocrafts 5be035a172 fix: restore ext-thumbnail disk lookup in get_cached_thumbnail
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.

Diocrafts 2dde4da5cf feat: thumbnail dedup — store thumbnails by blob_hash instead of file_id (#233)
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

Diocrafts 78fcf5f08f perf: move audio metadata I/O to spawn_blocking + stream reextract_all
- 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)

Diocrafts 63bcd0ffe7 perf: non-blocking hash + parallel thumbnail generation
- 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.

Diocrafts a2aece0752 perf: scale thumbnail decode semaphore with available CPUs
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.
