The thumbnail ETag was "thumb-{file_id}-{size}-{format}", sent with
Cache-Control: public, max-age=31536000, immutable. Replacing a file's
content preserves its id — file_upload_service rebuilds the entity with
parts.id and a new hash, then fires on_file_updated, which deletes and
regenerates the thumbnails — so the server produced a new thumbnail while
still advertising the old ETag. Because `immutable` tells a conforming
browser not to revalidate at all inside the freshness window, clients kept
rendering the previous image for up to a year, unfixably.
Keyed on the content hash the directive becomes honest: a thumbnail is a
pure function of (source bytes, size, format), so that triple identifies
the response. New content yields a new ETag.
The same change fixes the opposite direction. A copy, or any dedup twin,
had a different id and therefore a different ETag, so clients refetched
bytes they already held even though both are served from the same derived
blob. Now identical content agrees on an ETag and revalidates to 304
across files, users and copies.
Both thumbnail endpoints were affected: the REST handler and the
NextCloud preview handler.
Cost is one PK lookup ahead of the 304 decision, where the id-keyed
version needed none — paid for by no longer serving stale images. It is
partly recovered: both handlers already resolved the same hash further
down for the render path, and that second lookup is now gone, so the
cache-miss path is unchanged and only the 304 path pays. The resolved
hash is also handed to get_cached_thumbnail instead of None, saving the
service its own lookup.
No new disclosure: content_hash is already on FileDto and returned by
GET /api/files/{id}.
Tests: thumbnail_etag_content_keyed.hurl covers invalidation — overwrite
in place via WebDAV PUT, assert the ETag changed, assert a client holding
the stale one gets 200 rather than 304. derived_blob_copy.hurl gains the
sharing direction: a copy answers with the SAME ETag and revalidates to
304, which is the one externally observable consequence of content-keying
and was not previously testable.
A fast self-hosted cloud for people who want files, calendars, contacts, and office editing without dragging a heavy stack behind them.

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.
Prebuilt binary
Binary releases (Linux musl amd64/arm64, macOS Intel/Apple Silicon)
are attached to every tagged release on GitHub — the whole SPA + all
operator subcommands + migrations bake into a single self-contained
executable. See docs/install/binary.md for
the download / verify / systemd walkthrough.
cargo binstall oxicloud works too once a release is out.
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.
Architecture and Deployment
OxiCloud follows a clean, hexagonal architecture so protocol handlers, business logic, and infrastructure stay separated.
- Backend: Rust + Axum
- Database: PostgreSQL
- Configuration: environment variables
- Default deployment: Docker Compose
- Additional packaging: Helm chart and Nix module
Architecture docs: internal architecture · caching architecture · database transactions · storage safety
