README

gitbase GitHub version Build Status codecov GoDoc Go Report Card

gitbase, is a SQL database interface to Git repositories.

This project is now part of source{d} Engine, which provides the simplest way to get started with a single command. Visit sourced.tech/engine for more information.

It can be used to perform SQL queries about the Git history and about the Universal AST of the code itself. gitbase is being built to work on top of any number of git repositories.

gitbase implements the MySQL wire protocol, it can be accessed using any MySQL client or library from any language.

src-d/go-mysql-server is the SQL engine implementation used by gitbase.

Status

The project is currently in alpha stage, meaning it's still lacking performance in a number of cases but we are working hard on getting a performant system able to process thousands of repositories in a single node. Stay tuned!

Examples

You can see some query examples in gitbase documentation.

Motivation and scope

gitbase was born to ease the analysis of git repositories and their source code.

Also, making it MySQL compatible, we provide the maximum compatibility between languages and existing tools.

It comes as a single self-contained binary and it can be used as a standalone service. The service is able to process local repositories and integrates with existing tools and frameworks to simplify source code analysis on a large scale. The integration with Apache Spark is planned and is currently under active development.
