Introducing bundler-leak: A simple way to find known memory leaks in your dependencies

In this blog post I will introduce bundler-leak -- A bundler plugin to find known memory leaks in your dependencies.

The bundler-leak plugin is a fork of the famous bundler-audit .

Just like bundler-audit , bundler-leak works thanks to a couple of community-driven, open source projects. The first one is called ruby-mem-advisory-db: a text-based database of gems with known memory leak issues. Bundler Leak will compare gems stored in this database against your Gemfile. For example:

Audit a project's Gemfile.lock: $ bundle leak Name: therubyracer Version: 0.12.1 URL: https://github.com/cowboyd/therubyracer/pull/336 Title: Memory leak in WeakValueMap Solution: upgrade to ~> 0.12.3 Unpatched versions found!

Here is a sample project where you can play with bundler leak

The second project is called rubymem.com: A web application that will allow you to submit new leaky gems to the ruby-mem-advisory-db

Conclusion

We want to say thanks to all the contributors who contributed to bundler audit, it was a great inspiration for this plugin! If you want to learn more or contribute to bundler leak check the repository and submit an issue or PR.
