Project description

Комитет Git’a Безопасности

CircleCI branch Docker Stars

Комитет Git’a Безопасности (КGitБ) or Git security committee, is a commit message style enforcer. It comes in two parts, a web hook for github (lubyanka) and a local git commit-msg hook (resident). In an ideal world, a local hook should be enough, in practice, mistakes happen. The KGitB is here to ensure no mistakes are ever allowed through to infect your master branch.



Resident can be installed using pip using the following command. If you have a permission errors try using the –user flag with pip and add ~/.local/bin to your path. It should not require any dependencies.

pip install kgitb

To install in a local repository, go into it and run:

resident install --local

To set it up in another repository or multiple repository, you can path it a path to the repositor(y/ies) that you want to install it to:

resident install --path PATH_TO_REPO1 PATH_TO_REPO2

To set it up globally.

WARNING 0: Only works with git 2.9.0+

WARNING1: If it hasn’t been set yet, this option will set the core.hooksPath value in your .gitconfig to $HOME/.config/git-global-hooks. This will disable all local hooks in your repositories. If this is not what you want, you might want to have a look at hook templates.

WARNING2: global means for the user, system setup hasn’t been implemented (yet, PR anyone?).

resident install --global

If the webhook is correctly set up, you should see a APPROVED BY THE KGitB. line when you commit something, or if there are errors, the commit will fail with a description of the errors.

Currently there are no options to select. They will be added at a later point.


Lubyanka is the headquarters of all residents. It should be run on a server and setup with github to check all pull-requests. As excpected, if there are any violations, lubyanka will submit a helpful if somewhat authoritative comment message and set the status to error. If there are no violations it will set the status to success and congragulate you on a job well done.

To run lubyanka, get a copy of the code, install the requirements and execute it with the following commands:

git clone
cd komitet-gita-bezopasnosti
pip install -r requirements.txt

If you use docker remember to set the GH_TOKEN environment variable and link to port 5000.

The github token is needed to write comments, set the pr status as well as access any private repo.


КGitБ conventions are closely related to the angularJS commit conventions slightly revised as follow.

Commit Message Format

Each commit message consists of a header, and optionaly a body and a footer. The header has a special format that includes a type, a scope and a subject:

<type>(<scope>): <subject>

The header is mandatory.

Any line of the commit message cannot be longer 72 characters! This allows the message to be easier to read on GitHub as well as in various git tools.


  • feat: A new feature
  • fix: A bug fix
  • chore: Project boring stuff (like bumping a dependency version).
  • doc: Documentation only changes
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • refactor: A code change that neither fixes a bug nor adds a feature
  • perf: A code change that improves performance
  • test: Adding missing tests
  • revert: Reverting a previous commit.
  • version: To cover any version update.


The scope could be anything specifying place of the commit change. For example $location, $browser, $compile, $rootScope, ngHref, ngClick, ngView, etc…


The subject contains succinct description of the change:

  • use the imperative, present tense: “change” not “changed” nor “changes”
  • don’t capitalize first letter


Just as in the subject, use the imperative, present tense: “change” not “changed” nor “changes”. The body should include the motivation for the change and contrast this with previous behavior.


All contributions are of course welcome, please submit them as pull-requests and make sure that you are not in violation of the kgitb rules. If you need ideas: * Add rules list and documentation * resident, add –template, –template–system and –system install * resident, add lubyanka command line options for customizing rules * lubyanka, add origin of connection check cfr * lubyanka, add setup script * packaging, figure out how extra_requires works.

to test your changes please use tox and py.test, you should be able to install them by running:

pip install -r dev-requirements.txt

and run the tests using:



  • generate README.rst

    pandoc --from=markdown --to=rst --output=README.rst
  • publish

    python sdist upload
