# Kallithea README

## About

Kallithea is a fast and powerful management tool for Mercurial and Git with a built-in push/pull server, full text search and code-review. It works on http/https and has a built in permission/authentication system with the ability to authenticate via LDAP or ActiveDirectory. Kallithea also provides simple API so it’s easy to integrate with existing external systems.

Kallithea is similar in some respects to GitHub or Bitbucket, however Kallithea can be run as standalone hosted application on your own server. It is open-source donationware and focuses more on providing a customised, self-administered interface for Mercurial and Git repositories. Kallithea works on Unix-like systems and Windows, and is powered by the vcs library created by Łukasz Balcerzak and Marcin Kuźmiński to uniformly handle multiple version control systems.

Kallithea was forked from RhodeCode in July 2014 and has been heavily modified.

## Installation

Kallithea requires Python 2.x and it is recommended to install it in a virtualenv. Official releases of Kallithea can be installed with:

    pip install kallithea

The development repository is kept very stable and used in production by the developers – you can do the same.

Please visit https://docs.kallithea-scm.org/en/latest/installation.html for more details.

There is also an experimental Puppet module for installing and setting up Kallithea. Currently, only basic functionality is provided, but it is still enough to get up and running quickly, especially for people without Python background. See https://docs.kallithea-scm.org/en/latest/installation_puppet.html for further information.

## Source code

The latest sources can be obtained from https://kallithea-scm.org/repos/kallithea.

The issue tracker and a repository mirror can be found at Bitbucket on https://bitbucket.org/conservancy/kallithea.

## Kallithea features

- Has its own middleware to handle Mercurial and Git protocol requests. Each request is authenticated and logged together with IP address.
- Built for speed and performance. You can make multiple pulls/pushes simultaneously. Proven to work with thousands of repositories and users.
- Supports http/https, LDAP, AD, proxy-pass authentication.
- Full permissions (private/read/write/admin) together with IP restrictions for each repository, additional explicit forking, repositories group and repository creation permissions.
- User groups for easier permission management.
- Repository groups let you group repos and manage them easier. They come with permission delegation features, so you can delegate groups management.
- Users can fork other users repos, and compare them at any time.
- Built-in versioned paste functionality (Gist) for sharing code snippets.
- Integrates easily with other systems, with custom created mappers you can connect it to almost any issue tracker, and with a JSON-RPC API you can make much more.
- Built-in commit API lets you add, edit and commit files right from Kallithea web interface using simple editor or upload binary files using simple form.
- Powerful pull request driven review system with inline commenting, changeset statuses, and notification system.
- Importing and syncing repositories from remote locations for Git, Mercurial and Subversion.
- Mako templates let you customize the look and feel of the application.
- Beautiful diffs, annotations and source code browsing all colored by pygments. Raw diffs are made in Git-diff format for both VCS systems, including Git binary-patches.
- Mercurial and Git DAG graphs and Flot-powered graphs with zooming and statistics to track activity for repositories.
- Admin interface with user/permission management. Admin activity journal, logs pulls, pushes, forks, registrations and other actions made by all users.
- Server side forks. It is possible to fork a project and modify it freely without breaking the main repository.
- reST and Markdown README support for repositories.
- Full text search powered by Whoosh on the source files, commit messages, and file names. Built-in indexing daemons, with optional incremental index build (no external search servers required all in one application).
- Setup project descriptions/tags and info inside built in DB for easy, non-filesystem operations.
- Intelligent cache with invalidation after push or project change, provides high performance and always up to date data.
- RSS/Atom feeds, Gravatar support, downloadable sources as zip/tar/gz.
- Optional async tasks for speed and performance using Celery.
- Backup scripts can do backup of whole app and send it over scp to desired location.
- Based on Pylons, SQLAlchemy, SQLite, Whoosh, vcs.

## License

Kallithea is released under the GPLv3 license. Kallithea is a Software Freedom Conservancy project and thus controlled by a non-profit organization. No commercial entity can take ownership of the project and change the direction.

Kallithea started out as an effort to make sure the existing GPLv3 codebase would stay available under a legal license. Kallithea thus has to stay GPLv3 compatible ... but we are also happy it is GPLv3 and happy to keep it that way. A different license (such as AGPL) could perhaps help attract a different community with a different mix of Free Software people and companies but we are happy with the current focus.

## Community

Kallithea is maintained by its users who contribute the fixes they would like to see.

  > Please try to read the documentation before posting any issues, especially the troubleshooting section

## Online documentation

Online documentation for the current version of Kallithea is available at https://pythonhosted.org/Kallithea/. Documentation for the current development version can be found on https://docs.kallithea-scm.org/.

You can also build the documentation locally: go to `docs/` and run:

    make html

Note

You need to have Sphinx installed to build the documentation. If you don’t have Sphinx installed you can install it via the command: `pip install sphinx` .

## Converting from RhodeCode

Currently, you have two options for working with an existing RhodeCode database:

- keep the database unconverted (intended for testing and evaluation)
- convert the database in a one-time step

### Maintaining interoperability

Interoperability with RhodeCode 2.2.X installations is provided so you don’t have to immediately commit to switching to Kallithea. This option will most likely go away once the two projects have diverged significantly.

To run Kallithea on a RhodeCode database, run:

    echo "BRAND = 'rhodecode'" > kallithea/brand.py

This location will depend on where you installed Kallithea. If you installed via:

    python2 setup.py install

then you will find this location at `$VIRTUAL_ENV/lib/python2.7/site-packages/Kallithea-0.1-py2.7.egg/kallithea`.

### One-time conversion

Alternatively, if you would like to convert the database for good, you can use a helper script provided by Kallithea. This script will operate directly on the database, using the database string you can find in your `production.ini` (or `development.ini`) file. For example, if using SQLite:

    cd /path/to/kallithea
    cp /path/to/rhodecode/rhodecode.db kallithea.db
    pip install sqlalchemy-migrate
    python2 kallithea/bin/rebranddb.py sqlite:///kallithea.db

Note

If you started out using the branding interoperability approach mentioned above, watch out for stray brand.pyc after removing brand.py.

### Git hooks

After switching to Kallithea, it will be necessary to update the Git hooks in your repositories. If not, the Git hooks from RhodeCode will still be called, which will cause `git push` to fail every time.

If you do not have any custom Git hooks deployed, perform the following steps (this may take some time depending on the number and size of repositories you have):

1. Log-in as an administrator.
2. Open page Admin > Settings > Remap and Rescan.
3. Turn on the option Install Git Hooks.
4. Turn on the option Overwrite existing Git hooks.
5. Click on the button Rescan Repositories.

If you do have custom hooks, you will need to merge those changes manually. In order to get sample hooks from Kallithea, the easiest way is to create a new Git repository, and have a look at the hooks deployed there.
