GitPython is a Python library used to interact with Git repositories
I started working on GitPython in 2009, back in the days when Python was 'my thing' and I had great plans with it. Of course, back in the days, I didn't really know what I was doing and this shows in many places. Somewhat similar to Python this happens to be 'good enough', but at the same time is deeply flawed and broken beyond repair.
By now, GitPython is widely used and I am sure there is a good reason for that, it's something to be proud of and happy about. The community is maintaining the software and is keeping it relevant for which I am absolutely grateful. For the time to come I am happy to continue maintaining GitPython, remaining hopeful that one day it won't be needed anymore.
More than 15 years after my first meeting with 'git' I am still in excited about it, and am happy to finally have the tools and
probably the skills to scratch that itch of mine: implement git
in a way that makes tool creation a piece of cake for most.
If you like the idea and want to learn more, please head over to gitoxide, an implementation of 'git' in Rust.
GitPython is a python library used to interact with git repositories, high-level like git-porcelain, or low-level like git-plumbing.
It provides abstractions of git objects for easy access of repository data often backed by calling the git
command-line program.
This project is in maintenance mode, which means that
The project is open to contributions of all kinds, as well as new maintainers.
GitPython needs the git
executable to be installed on the system and available in your PATH
for most operations.
If it is not in your PATH
, you can help GitPython find it by setting
the GIT_PYTHON_GIT_EXECUTABLE=<path/to/git>
environment variable.
The list of dependencies are listed in ./requirements.txt
and ./test-requirements.txt
.
The installer takes care of installing them for you.
GitPython and its required package dependencies can be installed in any of the following ways, all of which should typically be done in a virtual environment.
To obtain and install a copy from PyPI, run:
pip install GitPython
(A distribution package can also be downloaded for manual installation at the PyPI page.)
If you have downloaded the source code, run this from inside the unpacked GitPython
directory:
pip install .
To clone the the GitHub repository from source to work on the code, you can do it like so:
git clone https://github.com/gitpython-developers/GitPython
cd GitPython
./init-tests-after-clone.sh
On Windows, ./init-tests-after-clone.sh
can be run in a Git Bash shell.
If you are cloning your own fork, then replace the above git clone
command with one that gives the URL of your fork. Or use this gh
command (assuming you have gh
and your fork is called GitPython
):
gh repo clone GitPython
Having cloned the repo, create and activate your virtual environment.
Then make an editable install:
pip install -e ".[test]"
In the less common case that you do not want to install test dependencies, pip install -e .
can be used instead.
GitPython is not suited for long-running processes (like daemons) as it tends to
leak system resources. It was written in a time where destructors (as implemented
in the __del__
method) still ran deterministically.
In case you still want to use it in such a context, you will want to search the
codebase for __del__
implementations and call these yourself when you see fit.
Another way assure proper cleanup of resources is to factor out GitPython into a separate process which can be dropped periodically.
See Issue #525.
Important: Right after cloning this repository, please be sure to have executed
the ./init-tests-after-clone.sh
script in the repository root. Otherwise
you will encounter test failures.
Ensure testing libraries are installed. This is taken care of already if you installed with:
pip install -e ".[test]"
Otherwise, you can run:
pip install -r test-requirements.txt
To test, run:
pytest
To lint, and apply automatic code formatting, run:
pre-commit run --all-files
make lint
black .
To typecheck, run:
mypy -p git
The same linting, and running tests on all the different supported Python versions, will be performed:
tox
(this skips any Python versions you don't have installed).Specific tools:
mypy
, pytest
, coverage.py
, and black
are in ./pyproject.toml
.flake8
is in the ./.flake8
file.Orchestration tools:
pre-commit
is in the ./.pre-commit-config.yaml
file.tox
is in ./tox.ini

Please only use releases from pypi
as you can verify the respective source

This script shows how to verify the tarball was indeed created by the authors of this project:

gpg --verify gitpython-signature.asc gitpython.whl
which outputs
gpg: Signature made Fr 4 Sep 10:04:50 2020 CST
gpg: using RSA key 27C50E7F590947D7273A741E85194C08421980C9
gpg: Good signature from "Sebastian Thiel (YubiKey USB-C) <byronimo@gmail.com>" [ultimate]
gpg: aka "Sebastian Thiel (In Rust I trust) <sebastian.thiel@icloud.com>" [ultimate]
You can verify that the keyid indeed matches the release-signature key provided in this repository by looking at the keys details:
gpg --list-packets ./release-verification-key.asc
You can verify that the commit adding it was also signed by it using:
git show --show-signature ./release-verification-key.asc
If you would like to trust it permanently, you can import and sign it:
gpg --import ./release-verification-key.asc
gpg --edit-key 4C08421980C9
