git tool to help manage upstream repositories

Project description

  • What is git-upstream?

git-upstream is an open source Python application that can be used to keep in sync with upstream open source projects, mainly OpenStack.

The main usecase for this tool is for people who are doing active contributions to repositories that are mirrors of OpenStack repositories, with the intention that most of those contributions will be submitted to at some point. If you are running a public cloud based on OpenStack, having local changes needed to use it in your environment, you can use git-upstream to stay up to date with the upstream master in a easier way (with respect to using raw git commands).

git-upstream provides new git subcommands to support rebasing of local-carried patches on top of upstream repositories. It provides commands to ease the use of git for who needs to integrate big upstream projects in their environment. The operations are performed using Git commands.

  • What git-upstream is not

The name of this tool includes the “git-” prefix because of the Git naming convention that a Git subcommand must have. So, as git-review (usually invoked with “git review […]”), this tool can be invoked using “git upstream […]”. That said, and even if git-upstream currently uses Change-Ids, it is not strictly related to git-review. In other words, git-review can (and most of the time will) be used without even knowing about git-upstream existence.

  • How can I contribute to git-upstream?

Git-upstream is in OpenStack:

As for any other OpenStack project, contributions are submitted thru the Gerrit review system.

To summarise:

  1. create a Gerrit account (that is, a launchpad identity)

click on the “Sign in” link in the upper right corner here:

  1. install git-review

pip install git-review

  1. clone the repo

git clone

  1. setup to work with Gerrit

cd git-upstream git review -s

git-review will ask the username to use to submit changes to, just enter the name you have registered in 1)

  1. add cool features or fix nasty bugs

  2. create your commit as usual

git add/rm <…> git commit

  1. submit the change for review

git review

That’s it. You can see your change signing in to your account.

Hold on tight, someone will come in shortly and will review your change! Meanwhile, you can join the OpenStack community on IRC. There is also a specific channel for git-upstream:

Before writing new code, it is always a good idea to check if the required change is already in Gerrit:,n,z
