GitPython

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, and additionally allows you to access the git repository more directly using either a pure python implementation, or the faster, but more resource intensive git command implementation.

The object database implementation is optimized for handling large quantities of objects and large datasets, which is achieved by using low-level structures and data streaming.

REQUIREMENTS

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.

• Git (1.7.x or newer)
• Python 2.7 to 3.5, while python 2.6 is supported on a best-effort basis.

The list of dependencies are listed in ./requirements.txt and ./test-requirements.txt. The installer takes care of installing them for you.

INSTALL

If you have downloaded the source code:

python setup.py install

or if you want to obtain a copy from the Pypi repository:

pip install GitPython

Both commands will install the required package dependencies.

A distribution package can be obtained for manual installation at:

http://pypi.python.org/pypi/GitPython

If you like to clone from source, you can do it like so:

git clone https://github.com/gitpython-developers/GitPython
git submodule update --init --recursive
./init-tests-after-clone.sh

Limitations

Leakage of System Resources

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.

Windows support

For Windows, we do regularly test it on Appveyor CI but not all test-cases pass - you may help improve them by exploring Issue #525.

Python 2.6

Python 2.6 is supported on best-effort basis; which means that it is likely to deteriorate over time.

RUNNING TESTS

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.

On Windows, make sure you have git-daemon in your PATH. For MINGW-git, the git-daemon.exe exists in Git\mingw64\libexec\git-core\; CYGWIN has no daemon, but should get along fine with MINGW's.

The easiest way to run tests is by using tox a wrapper around virtualenv. It will take care of setting up environments with the proper dependencies installed and execute test commands. To install it simply:

pip install tox

Then run:

tox

For more fine-grained control, you can use nose.

INFRASTRUCTURE

• User Documentation
• Questions and Answers
• Please post on stackoverflow and use the gitpython tag
• Issue Tracker
  • Post reproducible bugs and feature requests as a new issue. Please be sure to provide the following information if posting bugs:
    • GitPython version (e.g. import git; git.__version__)
    • Python version (e.g. python --version)
    • The encountered stack-trace, if applicable
    • Enough information to allow reproducing the issue

How to make a new release

• Update/verify the version in the VERSION file
• Update/verify that the changelog has been updated
• Commit everything
• Run git tag <version> to tag the version in Git
• Run make release
• Finally, set the upcoming version in the VERSION file, usually be incrementing the patch level, and possibly by appending -dev. Probably you want to git push once more.

How to verify a release

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

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

curl https://pypi.python.org/packages/7e/13/2a556eb97dcf498c915e5e04bb82bf74e07bb8b7337ca2be49bfd9fb6313/GitPython-2.1.5-py2.py3-none-any.whl\#md5\=d3ecb26cb22753f4414f75f721f6f626z  > gitpython.whl
curl https://pypi.python.org/packages/7e/13/2a556eb97dcf498c915e5e04bb82bf74e07bb8b7337ca2be49bfd9fb6313/GitPython-2.1.5-py2.py3-none-any.whl.asc > gitpython-signature.asc
gpg --verify gitpython-signature.asc gitpython.whl

which outputs

gpg: Signature made Sat Jun 10 20:22:49 2017 CEST using RSA key ID 3B07188F
gpg: Good signature from "Sebastian Thiel (In Rust I trust!) <[email protected]>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 4477 ADC5 977D 7C60 D2A7  E378 9FEE 1C6A 3B07 188F

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 9FEE1C6A3B07188F
> sign
> save

Afterwards verifying the tarball will yield the following:

$ gpg --verify gitpython-signature.asc gitpython.whl
gpg: Signature made Sat Jun 10 20:22:49 2017 CEST using RSA key ID 3B07188F
gpg: Good signature from "Sebastian Thiel (In Rust I trust!) <[email protected]>" [ultimate]

DEVELOPMENT STATUS

Now that there seems to be a massive user base, this should be motivation enough to let git-python return to a proper state, which means

• no open pull requests
• no open issues describing bugs
