Setup

=====

Setting up Kallithea

--------------------

First, you will need to create a Kallithea configuration file. Run the

following command to do so::

    gearbox make-config my.ini

This will create the file ``my.ini`` in the current directory. This

configuration file contains the various settings for Kallithea, e.g.

proxy port, email settings, usage of static files, cache, Celery

Next, you need to create the databases used by Kallithea. It is recommended to

use PostgreSQL or SQLite (default). If you choose a database other than the

default, ensure you properly adjust the database URL in your ``my.ini``

configuration file to use this other database. Kallithea currently supports

PostgreSQL, SQLite and MySQL databases. Create the database by running

the following command::

    gearbox setup-db -c my.ini

This will prompt you for a "root" path. This "root" path is the location where

Kallithea will store all of its repositories on the current machine. After

entering this "root" path ``setup-db`` will also prompt you for a username

and password for the initial admin account which ``setup-db`` sets

up for you.

The ``setup-db`` values can also be given on the command line.

Example::

    gearbox setup-db -c my.ini --user=nn --password=secret --email=nn@example.com --repos=/srv/repos

The ``setup-db`` command will create all needed tables and an

admin account. When choosing a root path you can either use a new

empty location, or a location which already contains existing

repositories. If you choose a location which contains existing

repositories Kallithea will add all of the repositories at the chosen

location to its database.  (Note: make sure you specify the correct

path to the root).

.. note:: the given path for Mercurial_ repositories **must** be write

          accessible for the application. It's very important since

          the Kallithea web interface will work without write access,

          but when trying to do a push it will fail with permission

          denied errors unless it has write access.

You are now ready to use Kallithea. To run it simply execute::

    gearbox serve -c my.ini

- This command runs the Kallithea server. The web app should be available at

  http://127.0.0.1:5000. The IP address and port is configurable via the

  configuration file created in the previous step.

- Log in to Kallithea using the admin account created when running ``setup-db``.

- The default permissions on each repository is read, and the owner is admin.

  Remember to update these if needed.

- In the admin panel you can toggle LDAP, anonymous, and permissions

  settings, as well as edit more advanced options on users and

  repositories.

Internationalization (i18n support)

-----------------------------------

The Kallithea web interface is automatically displayed in the user's preferred

language, as indicated by the browser. Thus, different users may see the

application in different languages. If the requested language is not available

(because the translation file for that language does not yet exist or is

incomplete), the language specified in setting ``i18n.lang`` in the Kallithea

configuration file is used as fallback. If no fallback language is explicitly

specified, English is used.

If you want to disable automatic language detection and instead configure a

fixed language regardless of user preference, set ``i18n.enabled = false`` and

set ``i18n.lang`` to the desired language (or leave empty for English).

Using Kallithea with SSH

------------------------

Kallithea currently only hosts repositories using http and https. (The addition

of ssh hosting is a planned future feature.) However you can easily use ssh in

parallel with Kallithea. (Repository access via ssh is a standard "out of

the box" feature of Mercurial_ and you can use this to access any of the

repositories that Kallithea is hosting. See PublishingRepositories_)

Kallithea repository structures are kept in directories with the same name

as the project. When using repository groups, each group is a subdirectory.

This allows you to easily use ssh for accessing repositories.

In order to use ssh you need to make sure that your web server and the users'

login accounts have the correct permissions set on the appropriate directories.

.. note:: These permissions are independent of any permissions you

          have set up using the Kallithea web interface.

If your main directory (the same as set in Kallithea settings) is for

example set to ``/srv/repos`` and the repository you are using is

named ``kallithea``, then to clone via ssh you should run::

    hg clone ssh://user@kallithea.example.com/srv/repos/kallithea

Using other external tools such as mercurial-server_ or using ssh key-based

authentication is fully supported.

.. note:: In an advanced setup, in order for your ssh access to use

          the same permissions as set up via the Kallithea web

          interface, you can create an authentication hook to connect

          to the Kallithea db and run check functions for permissions

          against that.

Setting up Whoosh full text search

----------------------------------

Kallithea provides full text search of repositories using `Whoosh`__.

.. __: https://pythonhosted.org/Whoosh/

For an incremental index build, run::

    gearbox make-index -c my.ini

For a full index rebuild, run::

    gearbox make-index -c my.ini -f

The ``--repo-location`` option allows the location of the repositories to be overridden;

usually, the location is retrieved from the Kallithea database.

The ``--index-only`` option can be used to limit the indexed repositories to a comma-separated list::

    gearbox make-index -c my.ini --index-only=vcs,kallithea

To keep your index up-to-date it is necessary to do periodic index builds;

for this, it is recommended to use a crontab entry. Example::

    0  3  *  *  *  /path/to/virtualenv/bin/gearbox make-index -c /path/to/kallithea/my.ini

When using incremental mode (the default), Whoosh will check the last

modification date of each file and add it to be reindexed if a newer file is

available. The indexing daemon checks for any removed files and removes them

from index.

If you want to rebuild the index from scratch, you can use the ``-f`` flag as above,

or in the admin panel you can check the "build from scratch" checkbox.

.. _ldap-setup:

Setting up LDAP support

-----------------------

Kallithea supports LDAP authentication. In order

to use LDAP, you have to install the python-ldap_ package. This package is

available via PyPI, so you can install it by running::

    pip install python-ldap

.. note:: ``python-ldap`` requires some libraries to be installed on

          your system, so before installing it check that you have at

          least the ``openldap`` and ``sasl`` libraries.

Choose *Admin > Authentication*, click the ``kallithea.lib.auth_modules.auth_ldap`` button

and then *Save*, to enable the LDAP plugin and configure its settings.

Here's a typical LDAP setup::

 Connection settings

 Enable LDAP          = checked

 Host                 = host.example.com

 Account              = <account>

 Password             = <password>

 Connection Security  = LDAPS

 Certificate Checks   = DEMAND

 Search settings

 Base DN              = CN=users,DC=host,DC=example,DC=org

 LDAP Filter          = (&(objectClass=user)(!(objectClass=computer)))

 LDAP Search Scope    = SUBTREE

 Attribute mappings

 Login Attribute      = uid

 First Name Attribute = firstName

 Last Name Attribute  = lastName

 Email Attribute      = mail

If your user groups are placed in an Organisation Unit (OU) structure, the Search Settings configuration differs::

 Search settings

 Base DN              = DC=host,DC=example,DC=org

 LDAP Filter          = (&(memberOf=CN=your user group,OU=subunit,OU=unit,DC=host,DC=example,DC=org)(objectClass=user))

 LDAP Search Scope    = SUBTREE

Enable LDAP : required

    Whether to use LDAP for authenticating users.

.. _ldap_host:

Host : required

    LDAP server hostname or IP address. Can be also a comma separated
