๐Ÿ‚ Oxen

Create a world where everyone can contribute to an Artificial General Intelligence, starting with the data.

๐ŸŒพ What is Oxen?

Oxen at it's core is a data version control library, written in Rust. It's goals are to be fast, reliable, and easy to use. It's designed to be used in a variety of ways, from a simple command line tool, to a remote server to sync to, to integrations into other ecosystems such as python.

๐Ÿ“š Documentation

The documentation for the Oxen.ai tool chain can be found here.

๐Ÿ”จ Build & Run

Install Dependencies

Oxen is purely written in Rust ๐Ÿฆ€. You should install the Rust toolchain with rustup: https://www.rust-lang.org/tools/install.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

If you are a developer and want to learn more about adding code or the overall architecture start here. Otherwise, a quick start to make sure everything is working follows.

Build

cargo build

If on intel mac, you may need to build with the following

$ rustup target install x86_64-apple-darwin
$ cargo build --target x86_64-apple-darwin

If on Windows, you may need to add the following directories to the 'INCLUDE' environment variable

"C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\include"

"C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.27023\include"

"C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\Llvm\lib\clang\12.0.0\include"

These are example paths and will vary between machines. If you install 'C++ Clang tools for Windows' through Microsoft Visual Studio Build Tools, the directories can be located from the Visual Studio installation under 'BuildTools\VC\Tools'

Speed up the build process

You can use the mold linker to speed up builds (The MIT-licensed macOS version is sold).

Use the following instructions to install sold and configure cargo to use it for building Oxen:

git clone --depth=1 --single-branch https://github.com/bluewhalesystems/sold.git

mkdir sold/build
cd sold/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=c++ ..
cmake --build . -j $(nproc)
sudo cmake --install .

Then create .cargo/config.toml in your Oxen repo root with the following content:

[target.x86_64-unknown-linux-gnu]
rustflags = ["-C", "link-arg=-fuse-ld=/usr/local/bin/ld64.mold"]

[target.x86_64-apple-darwin]
rustflags = ["-C", "link-arg=-fuse-ld=/usr/local/bin/ld64.mold"]

For macOS with Apple Silicon, you can use the lld linker.

brew install llvm

Then create .cargo/config.toml in your Oxen repo root with the following:

[target.aarch64-apple-darwin]
rustflags = [ "-C", "link-arg=-fuse-ld=/opt/homebrew/opt/llvm/bin/ld64.lld", ]

Run

CLI

To run Oxen from the command line, add the Oxen/target/debug directory to the 'PATH' environment variable

export PATH="$PATH:/path/to/Oxen/target/debug"

On Windows, you can use

$env:PATH += ";/path/to/Oxen/target/debug" 

Initialize a new repository or clone an existing one

oxen init
oxen clone https://hub.oxen.ai/namespace/repository

This will create the .oxen dir in your current directory and allow you to run Oxen CLI commands

oxen status
oxen add images/
oxen commit -m "added images"
oxen push origin main

Oxen Server

To run a local Oxen Server, generate a config file and token to authenticate the user

./target/debug/oxen-server add-user --email ox@oxen.ai --name Ox --output user_config.toml

Copy the config to the default locations

mkdir ~/.oxen
mv user_config.toml ~/.oxen/user_config.toml
cp ~/.oxen/user_config.toml data/test/config/user_config.toml

Set where you want the data to be synced to. The default sync directory is ./data/ to change it set the SYNC_DIR environment variable to a path.

export SYNC_DIR=/path/to/sync/dir

You can also create a .env.local file in the /src/server directory which can contain the SYNC_DIR variable to avoid setting it every time you run the server.

Run the server

./target/debug/oxen-server start

To run the server with live reload, first install cargo-watch

cargo install cargo-watch

On Windows, you may need to use cargo-watch --locked

cargo install cargo-watch --locked

Then run the server like this

cargo watch -- cargo run --bin oxen-server start

Nix Flake

If you have Nix installed you can use the flake to build and run the server. This will automatically install and configure the required build toolchain dependencies for Linux & macOS.

nix build .#oxen-server
nix build .#oxen-cli
nix build .#liboxen
nix run .#oxen-server -- start
nix run .#oxen-cli -- init

To develop with the standard rust toolchain in a Nix dev shell:

nix develop -c $SHELL
cargo build
cargo run --bin oxen-server start
cargo run --bin oxen start

The flake also provides derviations to build OCI (Docker) images with the minimal set of dependencies required to build and run oxen & oxen-server.

nix build .#oci-oxen-server
nix build .#oci-oxen-cli

This will export the OCI image and can be loaded with:

docker load -i result

Unit & Integration Tests

Make sure your user is configured and server is running on the default port and host, by following these setup steps:

# Configure a user
mkdir ./data/test/runs
./target/debug/oxen-server add-user --email ox@oxen.ai --name Ox --output user_config.toml
cp user_config.toml data/test/config/user_config.toml
# Start the oxen-server
./target/debug/oxen-server start

Note: tests open up a lot of file handles, so limit num test threads if running everything.

You an also increase the number of open files your system allows ulimit before running tests:

ulimit -n 10240
cargo test -- --test-threads=$(nproc)

It can be faster (in terms of compilation and runtime) to run a specific test. To run a specific library test:

cargo test --lib test_get_metadata_text_readme

To run a specific integration test

cargo test --test test_rm test_rm_directory_restore_directory

To run with all debug output and run a specific test

env RUST_LOG=warn,liboxen=debug,integration_test=debug cargo test -- --nocapture test_command_push_clone_pull_push

To set a different test host you can set the OXEN_TEST_HOST environment variable

env OXEN_TEST_HOST=0.0.0.0:4000 cargo test

Oxen Server

Structure

Remote repositories have the same internal structure as local ones, with the caviate that all the data is in the .oxen dir and not duplicated into a "local workspace".

APIs

Server defaults to localhost 3000

set SERVER 0.0.0.0:3000

You can grab your auth token from the config file above (~/.oxen/user_config.toml)

set TOKEN <YOUR_TOKEN>

List Repositories

curl -H "Authorization: Bearer $TOKEN" "http://$SERVER/api/repos"

Create Repository

curl -H "Authorization: Bearer $TOKEN" -X POST -d '{"name": "MyRepo"}' "http://$SERVER/api/repos"

Docker

Create the docker image

docker build -t oxen/server:0.6.0 .

Run a container on port 3000 with a local filesystem mounted from /var/oxen/data on the host to /var/oxen/data in the container.

docker run -d -v /var/oxen/data:/var/oxen/data -p 3000:3001 --name oxen oxen/server:0.6.0

Or use docker compose

docker-compose up -d reverse-proxy
docker-compose up -d --scale oxen=4 --no-recreate
