Nextcloud app uploads sent application/octet-stream as Content-Type,
causing images to not be recognized. Now both WebDAV PUT and chunked
upload paths call refine_content_type() which detects via magic bytes,
then extension, then falls back to the client header. Also fixes
update_file() which previously hardcoded application/octet-stream.

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/.

1. Share password bypass (HIGH): enforce password check in get_shared_link_by_token,
verify_shared_link_password now returns ShareDto only on correct password.
2. WebDAV MOVE ownership (MEDIUM): add assert_owner on destination parent folder
for file moves in both PathResolver and legacy branches.
3. Path traversal defense-in-depth (LOW): add reject_path_traversal() to WebDAV,
CalDAV, and CardDAV handlers rejecting '..' segments at HTTP boundary.
4. Setup race condition (LOW): atomic INSERT ... ON CONFLICT DO NOTHING in
try_claim_initialization prevents duplicate admin creation.
- Add type aliases (FileRow, FolderRow, FolderRowPaginated, FolderRowOptUser) to reduce type complexity
- Simplify redundant closures in app_password_handler and webdav_handler
- Remove needless borrow in auth_handler
- Collapse nested if/let chains in login_lockout, webdav_lock, auth, rate_limit
- Box LockEntry in acquire() Err variant to fix large enum variant warning
- Rename DeviceCodeStatus::from_str to parse to avoid should_implement_trait lint
- Add #[allow(clippy::too_many_arguments)] and #[allow(clippy::result_unit_err)] where appropriate
- Convert integration_tests from cargo feature to custom cfg attribute
- Add check-cfg lint config in Cargo.toml for integration_tests cfg
Replace String with Arc<str> for fields that contain repeated static
values (mime_type, icon_class, icon_special_class, category) in
FileDto, FolderDto, and OptimizedFileContent.
These fields are computed from ~40 static lookup tables and cloned
on every request. With Arc<str>, clone becomes O(1) atomic increment
instead of O(n) heap allocation — saving thousands of allocations/s
under load.
Fields kept as String: id, name, path, folder_id, owner_id
(unique per item, rarely cloned).
Zero API impact — serde serializes Arc<str> identically to String.

Remove async-trait dependency and use native Rust async fn in traits.
Replace Arc<dyn Trait> with Arc<ConcreteType> throughout the codebase
to enable monomorphization and eliminate dynamic dispatch overhead.
Key changes:
- Remove write-behind cache (no implementation existed)
- Fix should_transcode static method call
- Use ContactStorageAdapter directly instead of dyn AddressBookUseCase
- Clean up unused trait imports across services and DI
https://claude.ai/code/session_01EbAFEfyJNLRmJHmmYDX3Tt
- Replace SHA-256 with BLAKE3 (~5x faster) for content-addressable hashing
in dedup_service, file_handler, file_upload_service, chunked_upload_service
- Add mimalloc as global allocator for 10-30% throughput improvement
- sha2 crate retained only for PKCE (OAuth2 standard requirement)
- BLAKE3 produces 64-char hex hashes (same format), no DB schema changes needed
Replace list_files_in_subtree (fetch_all → Vec) with stream_files_in_subtree
that returns a Pin<Box<dyn Stream<Item = Result<File/FileDto>>>> backed by a
PostgreSQL cursor via sqlx::fetch().
Changes:
- FileReadPort::stream_files_in_subtree() returns streaming cursor (no default)
- FileRetrievalUseCase::stream_files_in_subtree() maps File→FileDto on the fly
- FileBlobReadRepository: async_stream::try_stream! + sqlx::fetch() cursor
- batch_operations: consume stream into HashMap incrementally
- zip_service: consume stream into HashMap incrementally
- All stubs/mocks updated (return empty stream)
Eliminates:
- Double allocation: Vec<(9-tuple)> + Vec<File> materialized simultaneously
- Unbounded RAM proportional to subtree size (was ~500 bytes × N files)
- Latency: callers blocked until last row fetched from PG
RAM is now O(folders) for the HashMap, not O(files).
- Change SearchUseCase::search() return type to Arc<SearchResultsDto>
- Replace Cache<u64, SearchResultsDto> with Cache<u64, Arc<SearchResultsDto>>
- Eliminate .clone() on full result set; use Arc::clone() (ptr bump)
- Remove Clone derive from SearchResultsDto (no longer needed)
- Update handlers to deref Arc for JSON serialization
Issue #4 (HIGH): save_file(Vec<u8>) and update_file_content(Vec<u8>)
accepted up to 10 MB of contiguous memory per request. While the main
upload paths already used streaming, the WebDAV compat methods
(create_file, update_file) and the empty-file handler still used the
buffered path, creating a .to_vec() copy.
Changes:
- FileWritePort trait: remove save_file(Vec<u8>) and
update_file_content(Vec<u8>) — only streaming variants remain
- FileUploadUseCase trait: remove upload_file(Vec<u8>)
- file_upload_service.rs: create_file() and update_file() now spool
&[u8] to NamedTempFile + Sha256::digest, then delegate to streaming
path (save_file_from_temp / update_file_streaming)
- file_handler.rs: empty file uploads use upload_file_streaming with
- FileBlobWriteRepository: remove save_file and update_file_content impls
- StubFileWritePort, StubFileUploadUseCase, MockFileRepository: remove
corresponding dead method impls
Impact: impossible to accidentally use a buffered upload path. All
content goes through streaming with ~256 KB peak RAM. -166 LOC.
Replace String with Arc<str> for etag and content_type fields in the
content cache. String::clone() allocates and copies the full string on
every cache hit (O(n)), while Arc<str>::clone() is O(1) — just an atomic
ref-count increment.
This eliminates 2 heap allocations per cache hit on the hottest download
path. At 1000 req/s that is 2000 fewer alloc/dealloc cycles per second.
Changed files:
- cache_ports.rs: trait signatures String → Arc<str>
- file_content_cache.rs: CacheEntry fields, get/put methods, tests
- stubs.rs: StubContentCachePort signatures
- file_retrieval_service.rs: caller creates Arc<str> before put()
Replace BFS traversal that issued 2 SQL queries per folder (list_files +
list_folders) with 2 total queries using PostgreSQL ltree <@ operator:
1. list_subtree_folders: single GiST-indexed scan for all folders
2. list_files_in_subtree: single GiST-indexed join for all files
Files are grouped by folder_id in a HashMap, then iterated in directory
order (folders pre-sorted by path from SQL).
Changes across 4 architecture layers:
- Domain: FolderRepository::list_subtree_folders (default impl)
- Application ports: FolderUseCase, FileRetrievalUseCase, FileReadPort
- Application services: FolderService, FileRetrievalService passthroughs
- Infrastructure: PG implementations + ZipService rewrite
Query count: O(N) → O(1). Latency for 100-folder tree: ~200 round-trips → 3.
Solution C - Hybrid temp-file streaming:
- ZipPort trait now returns NamedTempFile instead of Vec<u8>
- ZipService writes to a temp file via ZipWriter<std::fs::File> (O(1) RAM)
- Files are read in 64KB stream chunks via get_file_stream() instead of get_file_content()
- HTTP response streams the temp file via ReaderStream (never loads full ZIP in memory)
- Temp file auto-deleted on drop after response completes
- Removed dead imports (HeaderName, HeaderValue, Cursor, Read)
- Parse email_verified from ID token and UserInfo endpoint
- Reject OIDC login if email is present and not verified
- Only applies when email is in OIDC claims (not required otherwise)
Run `cargo fmt` across all Rust source files to enforce consistent
formatting (import ordering, line wrapping, match arm braces).

Remove legacy abstractions that are no longer used after the
100% blob storage model migration (#113):
- IdMappingPort trait from application/ports/outbound.rs
- storage_mediator.rs module (StorageMediator trait + impls)
- StorageMediator impl from PathService
- write_behind_cache.rs (FS-based, incompatible with blob model)
The WriteBehindCachePort trait and Optional fields in services
are preserved for potential future blob-compatible caching.
-968 lines of dead code removed. Build clean, RC=0.
Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
get_authorize_url() was synchronous and fell back to constructing
{issuer}/authorize when the discovery cache was empty. This produced
incorrect URLs for providers like Keycloak whose authorization
endpoint is {issuer}/protocol/openid-connect/auth.
Made get_authorize_url() async so it can call get_discovery() to
fetch the real authorization_endpoint from .well-known/openid-configuration
before the first redirect. The discovery document is cached after the
initial fetch.
Security fixes for OIDC authentication flow:
1. CSRF state validation (High): State nonce is now stored server-side
and validated on callback (single-use, 600s TTL)
2. PKCE S256 (Medium): code_challenge/code_verifier pair generated per
RFC 9126, sent in authorize URL and token exchange
3. Nonce in ID token (Medium): Random nonce included in authorize URL,
verified against ID token claims to prevent token replay
4. Secure token delivery (Medium): Tokens no longer in URL fragments.
One-time exchange code redirected to frontend, tokens retrieved via
POST /api/auth/oidc/exchange endpoint (60s TTL, single-use)
5. Registration guard (Low): POST /api/auth/register returns 403 when
disable_password_login is active in OIDC-only mode
