LiteFS ![GitHub release (latest by date)](https://img.shields.io/github/v/release/superfly/litefs) ![Status](https://img.shields.io/badge/status-beta-blue) ![GitHub](https://img.shields.io/github/license/superfly/litefs) ====== LiteFS is a FUSE-based file system for replicating SQLite databases across a cluster of machines. It works as a passthrough file system that intercepts writes to SQLite databases in order to detect transaction boundaries and record changes on a per-transaction level in [LTX files](https://github.com/superfly/ltx). This project is actively maintained but is currently in a beta state. Please report any bugs as an issue on the GitHub repository. You can find a [Getting Started guide](https://fly.io/docs/litefs/getting-started/) on [LiteFS' documentation site](https://fly.io/docs/litefs/). Please see the [ARCHITECTURE.md](/docs/ARCHITECTURE.md) design document for details about how LiteFS works. ## SQLite TCL Test Suite It's a goal of LiteFS to pass the SQLite TCL test suite, however, this is currently a work in progress. LiteFS doesn't have database deletion implemented yet so that causes many tests to fail during teardown. To run a test from the suite against LiteFS, you can use the `Dockerfile.test` to run it in isolation. First build the Dockerfile: ```sh docker build -t litefs-test -f Dockerfile.test . ``` Then run it with the filename of the test you want to run. In this case, we are running `select1.test`: ```sh docker run --device /dev/fuse --cap-add SYS_ADMIN -it litefs-test select1.test ``` ## Contributing LiteFS contributions work a little different than most GitHub projects. If you have a small bug fix or typo fix, please PR directly to this repository. If you would like to contribute a feature, please follow these steps: 1. Discuss the feature in an issue on this GitHub repository. 2. Create a pull request to **your fork** of the repository. 3. Post a link to your pull request in the issue for consideration. This project has a roadmap and features are added and tested in a certain order. Additionally, it's likely that code style, implementation details, and test coverage will need to be tweaked so it's easier to for me to grab your implementation as a starting point when implementing a feature.
