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.
Refs #404
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The PROPFIND handlers (added in #153) handle the /caldav/{username}/ and
/carddav/{username}/ prefixes returned by discovery, but do so via an
expensive database call to distinguish usernames from UUIDs. The remaining
handlers (PUT, GET, DELETE, REPORT, PROPPATCH) don't handle the prefix
at all, causing 500 errors when standard clients (DAVx5, Apple Calendar,
Thunderbird) follow the discovery URLs.
This commit:
1. Adds a strip_username_prefix() helper that uses a UUID parse check
to distinguish collection IDs from usernames (no DB call needed).
2. Applies it to PUT, GET, DELETE, REPORT, and PROPPATCH handlers in
both caldav_handler.rs and carddav_handler.rs.
3. Refactors PROPFIND in both files to use the same UUID heuristic for
consistency, avoiding unnecessary database queries.
Includes 7 unit tests for the helper function.
- rate_limit: cache OXICLOUD_TRUST_PROXY_HEADERS in OnceLock<bool> to avoid
syscall on every request (~500ns → ~1ns)
- auth middleware: insert Arc<CurrentUser> instead of bare CurrentUser;
all 5 extractors now clone Arc (~1ns) instead of 4 Strings (~60-100ns)
- search_service: pre-compute query.to_lowercase() once before loops,
eliminating N redundant heap allocations per search
- 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
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
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

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.
