- normalize username into lowercase (this is already ASCII only)
- permit users to login with their username with insensitive case
- if a disabled account is reactivated and got a collision, it will normalize it too
- server will stop on collision (ex: 2 entries with `Alice` and `alice`)
in a such case admin can run:
```
oxicloud migrate lowercase-usernames --dry-run
```
then
```
oxicloud migrate lowercase-usernames
```
link are checking that email matches, +email alias are normalize into email
if email is already used on another account, link is not possible
not usurpation risk as the IDP is choosen by the admin
Benchmark-gated (benches/ROUND20.md), same rule as rounds 2-19: every change
ships with a BEFORE/AFTER counting-allocator micro-benchmark and a byte-value
equivalence gate; a non-winning AFTER is rolled back (never applied). The
rollback rule is encoded in the harness (GATE FAIL exit). All 8 sections pass.
Reproduce: cargo run --release --features bench --example bench_round20_micro
- A1 CalendarEvent iCal parse: replace the throwaway per-property
HashMap<String,Vec<String>> (DTSTART/DTEND/RECURRENCE-ID) with a direct
VALUE=DATE scan; prop_with_params kept #[cfg(test)] (6->2 allocs/event, 4.2x)
- A2 UserDto::from: add User::into_parts and MOVE image (<=512 KiB data URI)
+ ui_preferences JSON instead of cloning on every /api/auth/me (27->14 allocs)
- A3 parse_vcard: drop the per-line to_ascii_uppercase copy + the lines Vec;
promote ascii_ci_contains to common::text and share it (8->1 allocs/contact)
- A4 Calendar/AddressBook DTO: into_parts move incl. custom_properties map (18->10)
- I1 file-listing repos: collect::<Result<Vec>>() size-hints to 0 and grows from
capacity 0; pre-size with Vec::with_capacity (8->1 container reallocs, 4 sites)
- I4 plaintext_stream: lazy emit iterator instead of eager Vec collect (43x wall)
- C1 NC write_etag_element: borrowed pre-escaped quote events, no owned quoted
String/escape re-alloc; byte-identical output (3->0 allocs/PROPFIND row)
- C3 NC favorites REPORT: map.remove() move instead of get().clone() (~7 allocs/fav)
Deferred (documented in ROUND20.md): NC oc:id/trashbin buffer reuse, I1 sibling
CardDAV/CalDAV listing paths, Contact JSONB Json<Vec<_>> decode, dedup
settle_batch &str bind, and a fast DoS-resistant hasher for hot trusted-key maps
(needs a dependency decision).

- add resource kind filter (file, folder, drive) in shared section (localStorage stored)
- add user preferences serverside store
- add client side dotfile filter (show/hide dotfiles) (user perf stored, default: dotfiles are shown)
for security trashed dotfile are always displayed
protection added: if a folder has only hidden items, a notification invite user to display it
if a user rename or create a hidden item, a notification tells it to user
Every WebDAV / CalDAV / CardDAV request paid one full-row user fetch in
require_internal_user_layer just to read `is_external` (and the NC Basic
Auth middleware repeated it right after its own cache hit). That SELECT
includes the `image` column — a data URI of up to 512 KiB — so a sync
client issuing hundreds of PROPFINDs per minute dragged hundreds of MB
of avatar bytes out of Postgres to evaluate a boolean.
- New `UserFlags { role, is_external, active }` + a repo query selecting
only those three columns (inherent method, mirroring `update_image`).
- `AuthApplicationService::get_user_flags`: moka cache, 30 s TTL,
10k capacity. `change_user_role` / `set_user_active` invalidate
eagerly, so admin changes still apply immediately; anything else is
visible within the TTL — preserving the documented "no token rotation
needed" semantics at a per-request cost of zero DB round-trips when
warm.
- `require_internal_user`, `require_admin_user` and the NC Basic Auth
external check now go through the flags lookup.

- add coalesced protection to avoid mail bombing if an invited goes many grant in a short period
- add resentd method in share menu item (work for both internal and external users)
- user can disable email notification via his properties
- add env variable from admin to disable notifications
- OIDC JIT define the locale only at user creation, user can so change his preference later
- invited users will inherit inviter's locale
- email will use prefered_locale
- login to a new browser will use prefered_locale
username: now optional, if defined 2..64 chars
password: now optional (no mode __NO_PASSWORD...__)
oidc: now optional
important: if need Nextcloud, username must be defined

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.
- 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
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.
- Remove Serialize/Deserialize from File, Folder, Session, User, Contact entities
- Create contact_persistence_dto.rs for JSONB persistence in infrastructure layer
- Update contact_pg_repository to use persistence DTOs
- Fix dependency on zip crate (downgrade from 7.2.0 to 2.1.0)
- Fix unused variable warnings in main.rs
- Move PathService import from domain to infrastructure
- Add missing fields to CoreServices and RepositoryServices
- Create proper service initialization in main.rs
Clean Architecture improvements:
- Domain layer no longer depends on serde framework
- Persistence concerns isolated to infrastructure layer
- TokenClaims in auth_service.rs is only exception (required for JWT)
