git-review is a command-line tool for Git / Gerrit to submit a change or to fetch an existing one.
Note that Wikimedia Gerrit requires git-review version 1.27 or later.

After installing git (1, 2), creating a gerrit user account, setting up an ssh key (3, 4), and cloning a project repository (or example), you are ready to install git-review, a tool for working with Gerrit repositories so you don't have to remember some commands. Follow the instructions below for your operating system, and don't forget to configure it up afterwards!
Users of Debian or related distributions (e.g., Ubuntu, Mint) on a shared host usually do not have root access. If you cannot get your hosting administrator to install git-review for you, you can try to install it locally. Go to the appropriate section below
Having root access
You can do
sudo apt-get install git-review
sudo apt-get install python-pip sudo easy_install pip sudo pip install git-review
If you do not have easy_install set up, try
sudo apt-get install python-setuptools
If you don't have
apt-get but have
python installed, you can use this; see far below for special OS X instructions.
sudo easy_install pip sudo pip install git-review
If you have Ubuntu 20.04, try
sudo apt-get install python3-pip sudo pip3 install git-review
git review -s
in your cloned copy to setup to work with Gerrit. It will probably ask you for your commit username. Then it will automatically install the commit-msg hook.
Without root access
If you are on a shared host and your system does not have git-review, you can install it locally in your user directory.
1 virtualenv --python=/usr/bin/python2.6 virtualenv 2 virtualenv/bin/pip install git-review
If this is your first local install, or you have not done that already, extend your PATH to include the local binaries. There are two ways to do that. The more convervative way
lets the system look through all binary directories first, and only looks into the local binary directory if a command was not found elsewhere. If you want software installed locally in your home directory to override system programs, you need the inverse the sort order.
You probably did that earlier already. You may want to add either command to your login sequence to have it run automatically.
If you do not want to alter your PATH variable, you don't have to. In this case, you cannot use the command
git review but must remember to use
git review -s
respectively, in your cloned copy to set it up to work with Gerrit. It will probably ask you for your commit username. Then it will automatically install the commit-msg hook.
sudo yum install git-review
If, while using git-review, you see
ImportError: No module named requests, you'll need to install
sudo yum install python-requests
You may find that yum cannot find the git-review package -- in this case you can enable the EPEL repository and try again.
sudo dnf install git-review
Install (YaST) the
easy_install pip pip install git-review
As of OpenSUSE 13.1, git-review is included in the main repository, so you can use
sudo zypper in git-review
sudo pacman -S git-review
If you are running the unstable branch of nixpkgs, git-review is available as a package. Install with:
nix-env -i python2.7-git-review
Older branches of nixpkgs
Install python and pip:
nix-env -i -A pythonPackages.pip
Add ~/.local/bin to your path:
export PATH=$PATH:~/.local/bin echo 'export PATH=$PATH:~/.local/bin' >> ~/.bashrc
pip install git-review --user pip install --upgrade setuptools pip install --upgrade distribute
Install using pip Python package installer
Note: if you don't have
apt-get but have
python installed, you can also install the latest version of git-review by using the python package installer.
The exact command depends on your distribution, either:
sudo apt-get install python-pip
sudo easy_install pip
pip is installed, you can use:
sudo pip install git-review
You can directly install git-review through ports.
cd /usr/ports/devel/git-review make install
Python is needed for git-review to function and pip is used for its installation:
- Install Python or upgrade to the most current version of Python 2 or Python 3.
- Important: Do not install Python in any directory with a space in its path as there is a pip bug (see ), use the default, e.g.
- During the Python installation, manually select Add python.exe to Path
- Otherwise, add your python scripts directory manually to the system path (Settings, Control panel, System, Advanced system settings, Environment variables, User variables, Path; e.g.
C:\Python34\;C:\Python34\Scripts\;). Different directories in path are delimited by a semicolon ";" only - do not add any whitespace to path list.
- Python 3.4 has pip already installed. Only if you have an older version, install pip by following the instructions here.
- Run Git Bash as Administrator (right click on icon for this option) and install git-review with the following command:
pip install git-review
- If you experience problems such as these:
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x03B55750>, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/git-review/
- try running:
pip install git-review --proxy=www-proxy-lon.uk.oracle.com:80
- the exact proxy to use can be extracted from http://wpad/wpad.dat file.
- To use
git review, you have to be in a git clone directory that already contains a (possibly hidden)
.gitreviewconfiguration file (see Setting up a repository for git-remote)
Mac OS X
Method 1 (Homebrew)
Works on OS X 10.11 El Capitan and later (verified on High Sierra 10.13.5):
- Install Homebrew
- Install git-review with
brew install git-review
Method 2 (Package Installer for Python “pip”)
Mac OS X comes with Python 2.7 (for now) but not the installation programs supported by Git and git-review.
- Open Terminal and change to a directory you're comfortable downloading test Git packages to (such as Downloads)
- Download and install the OS X Installer for Git (for OS X 10.8 and earlier only, OS X 10.9 ships with Git pre-installed)
- Install pip (Note: Already included in some older versions of OS X):
sudo easy_install pip
- Update pip/setuptools (for OS X 10.7 and earlier only)
sudo pip install -U setuptools
- Install git-review. OS X as of version "El Capitan" protects locations in the filesystem including
/System/Library/Frameworks/Python.framework/Versions/2.7/shareso typical install method will fail using sudo. Instead install git-review locally to your home folder like this:
pip install --user git-review
- Update your PATH shell variable to include the location of git-review which should be in
If you get the error
pkg_resources.DistributionNotFound: git-review, you may want to try nuking the pre-installed Python (/Library/Python/), installing Python via homebrew (
brew install python), and re-installing setuptools and git-review.
If you get a
git command not found after a seemingly successful installation, do not reinstall over the existing installation, but uninstall git-review and redo
sudo pip install -U setuptools
Setting up git-review
Follow the instructions in the Gerrit tutorial to configure git-review so that it uses "origin" as its default remote. This avoids confusion and conflicts between remotes named "gerrit" and "origin".
After cloning a repository, you need to set it up for using git-review. This will automatically happen the first time you try to submit a commit, but it's generally better to do it right after cloning.
cd MyNewProj git review -s
This may ask you for your git username, if it's different from the shell username you're using.
Internally, this does the following:
- checks whether accessing the remote repository works
- if it doesn't, asks for a username and tries again
- creates a remote called 'gerrit' that points to gerrit
- installs the commit-msg hook
Submitting changes with git-review
Submitting changes with git review does not involve a lot of commands:
git checkout -b mycoolfeature change files git commit -a git review
What happens when you submit a change
When you submit a change, git review does the following things:
- it looks up which branch to push to (production or whatever) in the .gitreview file. If it can't find this information, it pushes to master
- it figures out what "topic" to put on the revision (you can set the topic manually with
- if you're resubmitting a downloaded change, it will reuse the topic of the original change
- if your commit summary contains a bug number like
bug 12345, the topic will be
- otherwise, the topic will be the name of your local branch
- it rebases your change against the HEAD of the branch you're pushing to (use
-Rto skip this)
- if you are submitting more than one change at once, or submitting a change that's based on another unmerged change, it will ask you whether you really meant to do that (use
-yto skip this)
- it pushes the change for review
Downloading a change with git-review
When downloading a change from gerrit to review it or amend it, git-review offers an alternative to copy-pasting a magic incantation from the Gerrit web UI. All you need is the sequence number of the change in Gerrit, which you can find in the URL:
git review -d 2033
This will download the change, put it in a branch called
review/AUTHOR/TAG (if the change has no tag, the sequence number will be used instead), and switch to that branch.
After that, you can amend the downloaded change to improve it.
For problems and how to solve them, see Gerrit/Troubleshooting.
Troubleshooting for Windows
If this fails, you have a couple of options. The first is the use scp (secure copy) from within your local repository's directory, for each repository, before committing edits to it:
scp -P 29418 USERNAME@gerrit.wikimedia.org:hooks/commit-msg .git/hooks/commit-msg
The second is to try patching
c:\Python27\Scripts\git-review to make git-review work properly:
--- /c/Python27/Scripts/git-review-old Tue May 28 20:51:50 2013 +++ /c/Python27/Scripts/git-review Tue May 28 20:48:03 2013 @@ -952,6 +952,9 @@ config = get_config(os.path.join(top_dir, ".gitreview")) hook_file = os.path.join(git_dir, "hooks", "commit-msg") + # msysgit hacks to work around scp.exe (--aaron) + hook_file = unicode.replace( ".\%s" % os.path.relpath( hook_file ), "\\", "/" ) + defaultrebase = convert_bool( git_config_get_value("gitreview", "rebase", default=str(config['defaultrebase'])))
If using Python 2.x and git-review 1.17 or earlier, use
str.replace instead of
Another error encountered on Windows is:
... (top_dir, git_dir) = git_directories() ValueError: too many values to unpack (expected 2)
One solution to this is to change the return line of
git_directories() to use splitlines rather than its normal split function. Split looks for any whitespace and will produce this error when the path to your source code directory contains a space. Splitlines looks for newline characters and will not produce this same error.
