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.
- add /ocs/v1.php/cloud/user route (same as /ocs/v2.php/cloud/user )
- add also /remote.php/dav/avatars/{user}/{size}.png route (used by Nextcloud sync)
note: webp are transcoded in png, no cache but using pragma HTTP header
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}
This solve issue with 2 migrations made the same day, due to merge on pull request, DB migration is blocking
the same version prefix:
- 20260625000000_files_user_size_index.sql (Dio)
- 20260625000000_folder_tree_modified_at.sql (Ed)
They were renamed to ...0001 and ...0002 (disjoint versions) + protection like "IF NOT EXISTS"
I have opt for an automated clean up of old entry:
`DELETE FROM _sqlx_migrations WHERE version = 20260625000000;`
runned on startup
affected users: Dio, myself and any dev that wanted to work on this project since eb0ba58158
When a new browser visits the login page, the language selector runs first.
After the user selects a language and clicks continue, the code checked
system status and correctly showed the login panel when `initialized=true`
— but did not hide the "Set up administrator" link.
That link was only hidden by `showInitialPanel()`, which returns early
(without reaching the hide logic) whenever `isFirstRun()` is true. So on
any browser that had not previously stored the locale key, the link stayed
visible and clickable, leading users back to the admin setup panel even
after an admin already existed.
Fix: hide the link in the language-continue handler's `else` branch,
mirroring the same guard already present in `showInitialPanel()`.

GET /api/auth/me ran a synchronous O(N) SUM(size) over all the user's
files plus an unconditional UPDATE of auth.users on every call — one of
the most frequently hit endpoints — adding per-request latency, DB write
load, dead tuples and WAL even when nothing changed.
- /api/auth/me now serves the cached storage_used_bytes column instead of
recomputing it inline.
- New StorageUsageService::start_reconciliation_job runs a periodic sweep
on the maintenance pool that keeps the cached value current for every
mutation (uploads, deletes, trash), so freshness no longer depends on
hitting /me. Interval via OXICLOUD_STORAGE_USAGE_RECONCILE_SECS (default
600s, floored at 30s; first sweep deferred one interval to avoid boot load).
- update_storage_usage only writes when the value actually changes
(IS DISTINCT FROM), so the sweep produces no dead tuple / WAL on no-ops.
- New covering partial index idx_files_user_size_active makes the usage
SUM an index-only scan instead of a heap scan over all the user's files.
Also collapse the same pre-existing clippy collapsible_else_if in
carddav_handler that blocks the -D warnings gate on this base.

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.

TL;DR:
fix duplicate filename via:
```
docker exec <container> migrate-nfc-filenames --dry-run # preview
docker exec <container> migrate-nfc-filenames # execute
```
== issue ==
Last week I uploaded Capture d'écran 2026-06-03 à 20.04.24.png from the web. It synced down to Nextcloud on my Mac. Two minutes later, the Web UI was showing the file twice.
Both rows had:
- the same name
- the same size
- the same content hash
So why two rows? Because to PostgreSQL, the names weren't the same.
Web upload (browser → Postgres):
"é" stored as 1 codepoint (U+00E9) bytes: c3 a9 ← NFC
NiextCloud client (macOS → Postgres):
"é" stored as 2 codepoints (e + U+0301) bytes: 65 cc 81 ← NFD
macOS's APFS keeps filenames in NFD (decomposed); browsers send NFC (composed). Visually é and é are identical. To WHERE name = $1 they're two different keys. Our UNIQUE index on (folder_id, name, user_id) never fired — and the row count quietly drifted every time a Mac user touched an accented
filename.
== The fix is two halves ==
1. No new duplicates — every name-receiving boundary (file upload, NC PUT, rename, MOVE, path lookup) now NFC-normalizes before touching the database. The storage invariant becomes "every stored name is NFC".
2. Clean up existing data — one-shot migrate-nfc-filenames binary walks storage.files, NFC-normalizes any non-NFC row, and resolves the collisions we've accumulated. Same-content duplicates go to trash (recoverable); different-content collisions get renamed with a .duplicate suffix.
== use of the clean up ==
example of use (do not forget to define env **DATABASE_URL**)
either
`cargo run --bin migrate-nfc-filenames -- --dry-run`
or
`cargo build --bin migrate-nfc-filenames`
`./target/debug/migrate-nfc-filenames --dry-run`

DRY RUN — no rows were written. Re-run without --dry-run to apply.
```
once valid remove --dry-run
on a file or folder change, the etag of each parent will be updated, this is O(n)
this is required to ensure NextCloud client will be aware of changes
In the future a Cursor will be better, this will be for OxiCloud-desktop
issue: on folder creation view was wiped and displaying only the new folder
fix: add a "new" swimlane if in group mode and scroll up to the new created folder
- 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
- remove the hardcoded list of locales in favor of a discovry on start time
- server will stop on badly formatted locale .json
- add server.* entries for serer side translation
server side translation will be used for templating and email
note: no json in some embded html (like in /magic), amount of work was similar
