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`
example:
```
% ./target/debug/migrate-nfc-filenames --dry-run

A fast self-hosted cloud for people who want files, calendars, contacts, and office editing without dragging a heavy stack behind them.

If OxiCloud saves you setup time, RAM, or complexity, give it a star. If something is missing, ask for a feature or request a docs improvement.
Why People Try OxiCloud
OxiCloud is aimed at self-hosters, home labs, and small teams who want the useful parts of a cloud suite without the operational drag of a traditional PHP stack.
What pulls people in:
- Standard protocols first: WebDAV, CalDAV, and CardDAV are built in
- Useful product surface already there: files, previews, sharing, trash, search, favorites, and recent items
- Modern auth and admin basics: OIDC/SSO, quotas, roles, and shared links
- Better interoperability: native desktop and mobile clients work without custom sync tooling for basic access
- Lower deployment friction: Docker Compose, environment-based configuration, Helm chart, and Nix module
OxiCloud is not trying to mirror the full plugin ecosystem of Nextcloud. It is designed for a smaller stack, fast startup, and standards-based interoperability.
Quick Start
Docker Compose
Requires Docker and Docker Compose.
git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env
# If users will access OxiCloud through a domain or reverse proxy,
# set OXICLOUD_BASE_URL in .env before the first login.
docker compose up -d
Open http://localhost:8086.
Run from source
Requires Rust 1.93+ and PostgreSQL.
git clone https://github.com/AtalayaLabs/OxiCloud.git
cd OxiCloud
cp example.env .env
# If PostgreSQL runs on your host instead of Docker, update both
# OXICLOUD_DB_CONNECTION_STRING and DATABASE_URL to use localhost:5432.
cargo run

Help Shape OxiCloud
If you want OxiCloud to get better faster, use the repo like a product feedback loop, not just a code dump.
- Give it a star if you want more people to discover the project: Star OxiCloud
- Propose missing functionality: feature request
- Point out confusing onboarding or weak docs: documentation request
- Report breakage or regressions: bug report
- Build it with us: CONTRIBUTING.md
The best feature ideas usually come from real deployment pain. If you hit friction, open an issue and describe the workflow you want.
