 ==========================
 Installation on Unix/Linux
 ==========================
 
 The following describes three different ways of installing Kallithea:
 
 - :ref:`installation-source`: The simplest way to keep the installation
   up-to-date and track any local customizations is to run directly from
   source in a Kallithea repository clone, preferably inside a virtualenv
   virtual Python environment.
 
 - :ref:`installation-virtualenv`: If you prefer to only use released versions
   of Kallithea, the recommended method is to install Kallithea in a virtual
   Python environment using `virtualenv`. The advantages of this method over
   direct installation is that Kallithea and its dependencies are completely
   contained inside the virtualenv (which also means you can have multiple
   installations side by side or remove it entirely by just removing the
   virtualenv directory) and does not require root privileges.
 
 - :ref:`installation-without-virtualenv`: The alternative method of installing
   a Kallithea release is using standard pip. The package will be installed in
   the same location as all other Python packages you have ever installed. As a
   result, removing it is not as straightforward as with a virtualenv, as you'd
   have to remove its dependencies manually and make sure that they are not
   needed by other packages.
 
 Regardless of the installation method you may need to make sure you have
 appropriate development packages installed, as installation of some of the
 Kallithea dependencies requires a working C compiler and libffi library
 headers. Depending on your configuration, you may also need to install
 Git and development packages for the database of your choice.
 
 For Debian and Ubuntu, the following command will ensure that a reasonable
 set of dependencies is installed::
 
     sudo apt-get install build-essential git python-pip python-virtualenv libffi-dev python-dev
 
 For Fedora and RHEL-derivatives, the following command will ensure that a
 reasonable set of dependencies is installed::
 
     sudo yum install gcc git python-pip python-virtualenv libffi-devel python-devel
 
 .. _installation-source:
 
 
 Installation from repository source
 -----------------------------------
 
 To install Kallithea in a virtualenv_ using the stable branch of the development
 repository, follow the instructions below::
 
         hg clone https://kallithea-scm.org/repos/kallithea -u stable
         cd kallithea
         virtualenv ../kallithea-venv
         . ../kallithea-venv/bin/activate
         pip install --upgrade pip setuptools
         pip install -e .
         python2 setup.py compile_catalog   # for translation of the UI
 
 You can now proceed to :ref:`setup`.
 
 .. _installation-virtualenv:
 
 
 Installing a released version in a virtualenv
 ---------------------------------------------
 
 It is highly recommended to use a separate virtualenv_ for installing Kallithea.
 This way, all libraries required by Kallithea will be installed separately from your
 main Python installation and other applications and things will be less
 problematic when upgrading the system or Kallithea.
 An additional benefit of virtualenv_ is that it doesn't require root privileges.
 
 - Assuming you have installed virtualenv_, create a new virtual environment
   for example, in `/srv/kallithea/venv`, using the virtualenv command::
 
     virtualenv /srv/kallithea/venv
 
 - Activate the virtualenv_ in your current shell session and make sure the
   basic requirements are up-to-date by running::
 
     . /srv/kallithea/venv/bin/activate
     pip install --upgrade pip setuptools
 
 .. note:: You can't use UNIX ``sudo`` to source the ``virtualenv`` script; it
    will "activate" a shell that terminates immediately. It is also perfectly
    acceptable (and desirable) to create a virtualenv as a normal user.
 
 .. note:: Some dependencies are optional. If you need them, install them in
    the virtualenv too::
 
      pip install psycopg2
      pip install python-ldap
 
    This might require installation of development packages using your
    distribution's package manager.
 
 - Make a folder for Kallithea data files, and configuration somewhere on the
   filesystem. For example::
 
     mkdir /srv/kallithea
 
 - Go into the created directory and run this command to install Kallithea::
 
     pip install kallithea
 
   Alternatively, download a .tar.gz from http://pypi.python.org/pypi/Kallithea,
   extract it and run::
 
     pip install .
 
-- This will install Kallithea together with pylons_ and all other required
-  python libraries into the activated virtualenv.
+- This will install Kallithea together with all other required
+  Python libraries into the activated virtualenv.
 
 You can now proceed to :ref:`setup`.
 
 .. _installation-without-virtualenv:
 
 
 Installing a released version without virtualenv
 ------------------------------------------------
 
 For installation without virtualenv, 'just' use::
 
     pip install kallithea
 
 Note that this method requires root privileges and will install packages
 globally without using the system's package manager.
 
 To install as a regular user in ``~/.local``, you can use::
 
     pip install --user kallithea
 
 You can now proceed to :ref:`setup`.

 .. _overview:
 
 =====================
 Installation overview
 =====================
 
 Some overview and some details that can help understanding the options when
 installing Kallithea.
 
 
 Python environment
 ------------------
 
 **Kallithea** is written entirely in Python_ and requires Python version
 2.6 or higher. Python 3.x is currently not supported.
 
 Given a Python installation, there are different ways of providing the
 environment for running Python applications. Each of them pretty much
 corresponds to a ``site-packages`` directory somewhere where packages can be
 installed.
 
 Kallithea itself can be run from source or be installed, but even when running
 from source, there are some dependencies that must be installed in the Python
 environment used for running Kallithea.
 
 - Packages *could* be installed in Python's ``site-packages`` directory ... but
   that would require running pip_ as root and it would be hard to uninstall or
   upgrade and is probably not a good idea unless using a package manager.
 
 - Packages could also be installed in ``~/.local`` ... but that is probably
   only a good idea if using a dedicated user per application or instance.
 
 - Finally, it can be installed in a virtualenv_. That is a very lightweight
   "container" where each Kallithea instance can get its own dedicated and
   self-contained virtual environment.
 
 We recommend using virtualenv for installing Kallithea.
 
 
 Installation methods
 --------------------
 
 Kallithea must be installed on a server. Kallithea is installed in a Python
 environment so it can use packages that are installed there and make itself
 available for other packages.
 
 Two different cases will pretty much cover the options for how it can be
 installed.
 
 - The Kallithea source repository can be cloned and used -- it is kept stable and
   can be used in production. The Kallithea maintainers use the development
   branch in production. The advantage of installation from source and regularly
   updating it is that you take advantage of the most recent improvements. Using
   it directly from a DVCS also means that it is easy to track local customizations.
 
   Running ``pip install -e .`` in the source will use pip to install the
   necessary dependencies in the Python environment and create a
   ``.../site-packages/Kallithea.egg-link`` file there that points at the Kallithea
   source.
 
 - Kallithea can also be installed from ready-made packages using a package manager.
   The official released versions are available on PyPI_ and can be downloaded and
   installed with all dependencies using ``pip install kallithea``.
 
   With this method, Kallithea is installed in the Python environment as any
   other package, usually as a ``.../site-packages/Kallithea-X-py2.7.egg/``
   directory with Python files and everything else that is needed.
 
   (``pip install kallithea`` from a source tree will do pretty much the same
   but build the Kallithea package itself locally instead of downloading it.)
 
 
 Web server
 ----------
 
 Kallithea is (primarily) a WSGI_ application that must be run from a web
 server that serves WSGI applications over HTTP.
 
 Kallithea itself is not serving HTTP (or HTTPS); that is the web server's
 responsibility. Kallithea does however need to know its own user facing URL
 (protocol, address, port and path) for each HTTP request. Kallithea will
 usually use its own HTML/cookie based authentication but can also be configured
 to use web server authentication.
 
 There are several web server options:
 
 - Kallithea uses the Paste_ tool as command line interface. Paste provides
   ``paster serve`` as a convenient way to launch a Python WSGI / web server
   from the command line. That is perfect for development and evaluation.
   Actual use in production might have different requirements and need extra
   work to make it manageable as a scalable system service.
 
   Paste comes with its own built-in web server but Kallithea defaults to use
   Waitress_. Gunicorn_ is also an option. These web servers have different
   limited feature sets.
 
   The web server used by ``paster`` is configured in the ``.ini`` file passed
   to it. The entry point for the WSGI application is configured
   in ``setup.py`` as ``kallithea.config.middleware:make_app``.
 
 - `Apache httpd`_ can serve WSGI applications directly using mod_wsgi_ and a
   simple Python file with the necessary configuration. This is a good option if
   Apache is an option.
 
 - uWSGI_ is also a full web server with built-in WSGI module.
 
 - IIS_ can also server WSGI applications directly using isapi-wsgi_.
 
 - A `reverse HTTP proxy <https://en.wikipedia.org/wiki/Reverse_proxy>`_
   can be put in front of another web server which has WSGI support.
   Such a layered setup can be complex but might in some cases be the right
   option, for example to standardize on one internet-facing web server, to add
   encryption or special authentication or for other security reasons, to
   provide caching of static files, or to provide load balancing or fail-over.
   Nginx_, Varnish_ and HAProxy_ are often used for this purpose, often in front
   of a ``paster`` server that somehow is wrapped as a service.
 
 The best option depends on what you are familiar with and the requirements for
 performance and stability. Also, keep in mind that Kallithea mainly is serving
 dynamically generated pages from a relatively slow Python process. Kallithea is
 also often used inside organizations with a limited amount of users and thus no
 continuous hammering from the internet.

 =====
 Setup
 =====
 
 
 Setting up Kallithea
 --------------------
 
 First, you will need to create a Kallithea configuration file. Run the
 following command to do so::
 
     paster make-config Kallithea 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
 settings, and logging.
 
 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::
 
     paster setup-db 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::
 
     paster setup-db my.ini --user=nn --password=secret --email=[e-mail] --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::
 
     paster serve 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.
 
 
 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://[e-mail]/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::
 
     paster make-index my.ini
 
 For a full index rebuild, run::
 
     paster make-index 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::
 
     paster make-index 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/paster make-index /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 connection
  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:
 
 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
     list of servers to support LDAP fail-over.
 
 .. _Port:
 
 Port : optional
     Defaults to 389 for PLAIN un-encrypted LDAP and START_TLS.
     Defaults to 636 for LDAPS.
 
 .. _ldap_account:
 
 Account : optional
     Only required if the LDAP server does not allow anonymous browsing of
     records.  This should be a special account for record browsing.  This
     will require `LDAP Password`_ below.
 
 .. _LDAP Password:
 
 Password : optional
     Only required if the LDAP server does not allow anonymous browsing of
     records.
 
 .. _Enable LDAPS:
 
 Connection Security : required
     Defines the connection to LDAP server
 
     PLAIN
         Plain unencrypted LDAP connection.
         This will by default use `Port`_ 389.
 
     LDAPS
         Use secure LDAPS connections according to `Certificate
         Checks`_ configuration.
         This will by default use `Port`_ 636.
 
     START_TLS
         Use START TLS according to `Certificate Checks`_ configuration on an
         apparently "plain" LDAP connection.
         This will by default use `Port`_ 389.
 
 .. _Certificate Checks:
 
 Certificate Checks : optional
     How SSL certificates verification is handled -- this is only useful when
     `Enable LDAPS`_ is enabled.  Only DEMAND or HARD offer full SSL security
     with mandatory certificate validation, while the other options are
     susceptible to man-in-the-middle attacks.
 
     NEVER
         A serve certificate will never be requested or checked.
 
     ALLOW
         A server certificate is requested.  Failure to provide a
         certificate or providing a bad certificate will not terminate the
         session.
 
     TRY
         A server certificate is requested.  Failure to provide a
         certificate does not halt the session; providing a bad certificate
         halts the session.
 
     DEMAND
         A server certificate is requested and must be provided and
         authenticated for the session to proceed.
 
     HARD
         The same as DEMAND.
 
 .. _Custom CA Certificates:
 
 Custom CA Certificates : optional
     Directory used by OpenSSL to find CAs for validating the LDAP server certificate.
     Python 2.7.10 and later default to using the system certificate store, and
     this should thus not be necessary when using certificates signed by a CA
     trusted by the system.
     It can be set to something like `/etc/openldap/cacerts` on older systems or
     if using self-signed certificates.
 
 .. _Base DN:
 
 Base DN : required
     The Distinguished Name (DN) where searches for users will be performed.
     Searches can be controlled by `LDAP Filter`_ and `LDAP Search Scope`_.
 
 .. _LDAP Filter:
 
 LDAP Filter : optional
     A LDAP filter defined by RFC 2254.  This is more useful when `LDAP
     Search Scope`_ is set to SUBTREE.  The filter is useful for limiting
     which LDAP objects are identified as representing Users for
     authentication.  The filter is augmented by `Login Attribute`_ below.
     This can commonly be left blank.
 
 .. _LDAP Search Scope:
 
 LDAP Search Scope : required
     This limits how far LDAP will search for a matching object.
 
     BASE
         Only allows searching of `Base DN`_ and is usually not what you
         want.
 
     ONELEVEL
         Searches all entries under `Base DN`_, but not Base DN itself.
 
     SUBTREE
         Searches all entries below `Base DN`_, but not Base DN itself.
         When using SUBTREE `LDAP Filter`_ is useful to limit object
         location.
 
 .. _Login Attribute:
 
 Login Attribute : required
     The LDAP record attribute that will be matched as the USERNAME or
     ACCOUNT used to connect to Kallithea.  This will be added to `LDAP
     Filter`_ for locating the User object.  If `LDAP Filter`_ is specified as
     "LDAPFILTER", `Login Attribute`_ is specified as "uid" and the user has
     connected as "jsmith" then the `LDAP Filter`_ will be augmented as below
     ::
 
         (&(LDAPFILTER)(uid=jsmith))
 
 .. _ldap_attr_firstname:
 
 First Name Attribute : required
     The LDAP record attribute which represents the user's first name.
 
 .. _ldap_attr_lastname:
 
 Last Name Attribute : required
     The LDAP record attribute which represents the user's last name.
 
 .. _ldap_attr_email:
 
 Email Attribute : required
     The LDAP record attribute which represents the user's email address.
 
 If all data are entered correctly, and python-ldap_ is properly installed
 users should be granted access to Kallithea with LDAP accounts.  At this
 time user information is copied from LDAP into the Kallithea user database.
 This means that updates of an LDAP user object may not be reflected as a
 user update in Kallithea.
 
 If You have problems with LDAP access and believe You entered correct
 information check out the Kallithea logs, any error messages sent from LDAP
 will be saved there.
 
 Active Directory
 ^^^^^^^^^^^^^^^^
 
 Kallithea can use Microsoft Active Directory for user authentication.  This
 is done through an LDAP or LDAPS connection to Active Directory.  The
 following LDAP configuration settings are typical for using Active
 Directory ::
 
  Base DN              = OU=SBSUsers,OU=Users,OU=MyBusiness,DC=v3sys,DC=local
  Login Attribute      = sAMAccountName
  First Name Attribute = givenName
  Last Name Attribute  = sn
  Email Attribute     = mail
 
 All other LDAP settings will likely be site-specific and should be
 appropriately configured.
 
 
 Authentication by container or reverse-proxy
 --------------------------------------------
 
 Kallithea supports delegating the authentication
 of users to its WSGI container, or to a reverse-proxy server through which all
 clients access the application.
 
 When these authentication methods are enabled in Kallithea, it uses the
 username that the container/proxy (Apache or Nginx, etc.) provides and doesn't
 perform the authentication itself. The authorization, however, is still done by
 Kallithea according to its settings.
 
 When a user logs in for the first time using these authentication methods,
 a matching user account is created in Kallithea with default permissions. An
 administrator can then modify it using Kallithea's admin interface.
 
 It's also possible for an administrator to create accounts and configure their
 permissions before the user logs in for the first time, using the :ref:`create-user` API.
 
 Container-based authentication
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 In a container-based authentication setup, Kallithea reads the user name from
 the ``REMOTE_USER`` server variable provided by the WSGI container.
 
 After setting up your container (see `Apache with mod_wsgi`_), you'll need
 to configure it to require authentication on the location configured for
 Kallithea.
 
 Proxy pass-through authentication
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 In a proxy pass-through authentication setup, Kallithea reads the user name
 from the ``X-Forwarded-User`` request header, which should be configured to be
 sent by the reverse-proxy server.
 
 After setting up your proxy solution (see `Apache virtual host reverse proxy example`_,
 `Apache as subdirectory`_ or `Nginx virtual host example`_), you'll need to
 configure the authentication and add the username in a request header named
 ``X-Forwarded-User``.
 
 For example, the following config section for Apache sets a subdirectory in a
 reverse-proxy setup with basic auth:
 
 .. code-block:: apache
 
     <Location /someprefix>
       ProxyPass http://127.0.0.1:5000/someprefix
       ProxyPassReverse http://127.0.0.1:5000/someprefix
       SetEnvIf X-Url-Scheme https HTTPS=1
 
       AuthType Basic
       AuthName "Kallithea authentication"
       AuthUserFile /srv/kallithea/.htpasswd
       Require valid-user
 
       RequestHeader unset X-Forwarded-User

 Setting metadata in container/reverse-proxy
 """""""""""""""""""""""""""""""""""""""""""
 When a new user account is created on the first login, Kallithea has no information about
 the user's email and full name. So you can set some additional request headers like in the
 example below. In this example the user is authenticated via Kerberos and an Apache
 mod_python fixup handler is used to get the user information from a LDAP server. But you
 could set the request headers however you want.
 
 .. code-block:: apache
 
     <Location /someprefix>
       ProxyPass http://127.0.0.1:5000/someprefix
       ProxyPassReverse http://127.0.0.1:5000/someprefix
       SetEnvIf X-Url-Scheme https HTTPS=1
 
       AuthName "Kerberos Login"
       AuthType Kerberos
       Krb5Keytab /etc/apache2/http.keytab
       KrbMethodK5Passwd off
       KrbVerifyKDC on
       Require valid-user
 
       PythonFixupHandler ldapmetadata
 
       RequestHeader set X_REMOTE_USER %{X_REMOTE_USER}e
       RequestHeader set X_REMOTE_EMAIL %{X_REMOTE_EMAIL}e
       RequestHeader set X_REMOTE_FIRSTNAME %{X_REMOTE_FIRSTNAME}e
       RequestHeader set X_REMOTE_LASTNAME %{X_REMOTE_LASTNAME}e
     </Location>
 
 .. code-block:: python
 
     from mod_python import apache
     import ldap
 
     LDAP_SERVER = "ldap://server.mydomain.com:389"
     LDAP_USER = ""
     LDAP_PASS = ""
     LDAP_ROOT = "dc=mydomain,dc=com"
     LDAP_FILTER = "sAMAccountName=%s"
     LDAP_ATTR_LIST = ['sAMAccountName','givenname','sn','mail']
 
     def fixuphandler(req):
         if req.user is None:
             # no user to search for
             return apache.OK
         else:
             try:
                 if('\\' in req.user):
                     username = req.user.split('\\')[1]
                 elif('@' in req.user):
                     username = req.user.split('@')[0]
                 else:
                     username = req.user
                 l = ldap.initialize(LDAP_SERVER)
                 l.simple_bind_s(LDAP_USER, LDAP_PASS)
                 r = l.search_s(LDAP_ROOT, ldap.SCOPE_SUBTREE, LDAP_FILTER % username, attrlist=LDAP_ATTR_LIST)
 
                 req.subprocess_env['X_REMOTE_USER'] = username
                 req.subprocess_env['X_REMOTE_EMAIL'] = r[0][1]['mail'][0].lower()
                 req.subprocess_env['X_REMOTE_FIRSTNAME'] = "%s" % r[0][1]['givenname'][0]
                 req.subprocess_env['X_REMOTE_LASTNAME'] = "%s" % r[0][1]['sn'][0]
             except Exception, e:
                 apache.log_error("error getting data from ldap %s" % str(e), apache.APLOG_ERR)
 
             return apache.OK
 
 .. note::
    If you enable proxy pass-through authentication, make sure your server is
    only accessible through the proxy. Otherwise, any client would be able to
    forge the authentication header and could effectively become authenticated
    using any account of their liking.
 
 
 Integration with issue trackers
 -------------------------------
 
 Kallithea provides a simple integration with issue trackers. It's possible
 to define a regular expression that will match an issue ID in commit messages,
 and have that replaced with a URL to the issue. To enable this simply
 uncomment the following variables in the ini file::
 
     issue_pat = (?:^#|\s#)(\w+)
     issue_server_link = https://issues.example.com/{repo}/issue/{id}
     issue_prefix = #
 
 ``issue_pat`` is the regular expression describing which strings in
 commit messages will be treated as issue references. A match group in
 parentheses should be used to specify the actual issue id.
 
 The default expression matches issues in the format ``#<number>``, e.g., ``#300``.
 
 Matched issue references are replaced with the link specified in
 ``issue_server_link``. ``{id}`` is replaced with the issue ID, and
 ``{repo}`` with the repository name.  Since the # is stripped away,
 ``issue_prefix`` is prepended to the link text.  ``issue_prefix`` doesn't
 necessarily need to be ``#``: if you set issue prefix to ``ISSUE-`` this will
 generate a URL in the format:
 
 .. code-block:: html
 
   <a href="https://issues.example.com/example_repo/issue/300">ISSUE-300</a>
 
 If needed, more than one pattern can be specified by appending a unique suffix to
 the variables. For example::
 
     issue_pat_wiki = (?:wiki-)(.+)
     issue_server_link_wiki = https://wiki.example.com/{id}
     issue_prefix_wiki = WIKI-
 
 With these settings, wiki pages can be referenced as wiki-some-id, and every
 such reference will be transformed into:
 
 .. code-block:: html
 
   <a href="https://wiki.example.com/some-id">WIKI-some-id</a>
 
 
 Hook management
 ---------------
 
 Hooks can be managed in similar way to that used in ``.hgrc`` files.
 To manage hooks, choose *Admin > Settings > Hooks*.
 
 The built-in hooks cannot be modified, though they can be enabled or disabled in the *VCS* section.
 
 To add another custom hook simply fill in the first textbox with
 ``<name>.<hook_type>`` and the second with the hook path. Example hooks
 can be found in ``kallithea.lib.hooks``.
 
 
 Changing default encoding
 -------------------------
 
 By default, Kallithea uses UTF-8 encoding.
 This is configurable as ``default_encoding`` in the .ini file.
 This affects many parts in Kallithea including user names, filenames, and
 encoding of commit messages. In addition Kallithea can detect if the ``chardet``
 library is installed. If ``chardet`` is detected Kallithea will fallback to it
 when there are encode/decode errors.
 
 
 Celery configuration
 --------------------
 
 Kallithea can use the distributed task queue system Celery_ to run tasks like
 cloning repositories or sending emails.
 
 Kallithea will in most setups work perfectly fine out of the box (without
 Celery), executing all tasks in the web server process. Some tasks can however
 take some time to run and it can be better to run such tasks asynchronously in
 a separate process so the web server can focus on serving web requests.
 
 For installation and configuration of Celery, see the `Celery documentation`_.
 Note that Celery requires a message broker service like RabbitMQ_ (recommended)
 or Redis_.
 
 The use of Celery is configured in the Kallithea ini configuration file.
 To enable it, simply set::
 
   use_celery = true
 
 and add or change the ``celery.*`` and ``broker.*`` configuration variables.
 
 Remember that the ini files use the format with '.' and not with '_' like
 Celery. So for example setting `BROKER_HOST` in Celery means setting
 `broker.host` in the configuration file.
 
 To start the Celery process, run::
 
  paster celeryd <configfile.ini>
 
 .. note::
    Make sure you run this command from the same virtualenv, and with the same
    user that Kallithea runs.
 
 
 HTTPS support
 -------------
 
 Kallithea will by default generate URLs based on the WSGI environment.
 
 Alternatively, you can use some special configuration settings to control
 directly which scheme/protocol Kallithea will use when generating URLs:
 
 - With ``https_fixup = true``, the scheme will be taken from the
   ``X-Url-Scheme``, ``X-Forwarded-Scheme`` or ``X-Forwarded-Proto`` HTTP header
   (default ``http``).
 - With ``force_https = true`` the default will be ``https``.
 - With ``use_htsts = true``, Kallithea will set ``Strict-Transport-Security`` when using https.
 
 
 Nginx virtual host example
 --------------------------
 
 Sample config for Nginx using proxy:
 
 .. code-block:: nginx
 
     upstream kallithea {
         server 127.0.0.1:5000;
         # add more instances for load balancing
         #server 127.0.0.1:5001;
         #server 127.0.0.1:5002;
     }
 
     ## gist alias
     server {
        listen          443;
        server_name     gist.example.com;
        access_log      /var/log/nginx/gist.access.log;
        error_log       /var/log/nginx/gist.error.log;
 
        ssl on;
        ssl_certificate     gist.your.kallithea.server.crt;
        ssl_certificate_key gist.your.kallithea.server.key;
 
        ssl_session_timeout 5m;
 
        ssl_protocols SSLv3 TLSv1;
        ssl_ciphers DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:EDH-RSA-DES-CBC3-SHA:AES256-SHA:DES-CBC3-SHA:AES128-SHA:RC4-SHA:RC4-MD5;
        ssl_prefer_server_ciphers on;
 
        rewrite ^/(.+)$ https://kallithea.example.com/_admin/gists/$1;
        rewrite (.*)    https://kallithea.example.com/_admin/gists;
     }
 
     server {
        listen          443;
        server_name     kallithea.example.com
        access_log      /var/log/nginx/kallithea.access.log;
        error_log       /var/log/nginx/kallithea.error.log;
 
        ssl on;
        ssl_certificate     your.kallithea.server.crt;
        ssl_certificate_key your.kallithea.server.key;
 
        ssl_session_timeout 5m;
 
        ssl_protocols SSLv3 TLSv1;
        ssl_ciphers DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:EDH-RSA-DES-CBC3-SHA:AES256-SHA:DES-CBC3-SHA:AES128-SHA:RC4-SHA:RC4-MD5;
        ssl_prefer_server_ciphers on;
 
        ## uncomment root directive if you want to serve static files by nginx
        ## requires static_files = false in .ini file
        #root /srv/kallithea/kallithea/kallithea/public;
        include         /etc/nginx/proxy.conf;
        location / {
             try_files $uri @kallithea;
        }
 
        location @kallithea {
             proxy_pass      http://127.0.0.1:5000;
        }
 
     }
 
 Here's the proxy.conf. It's tuned so it will not timeout on long
 pushes or large pushes::
 
     proxy_redirect              off;
     proxy_set_header            Host $host;
     ## needed for container auth
     #proxy_set_header            REMOTE_USER $remote_user;
     #proxy_set_header            X-Forwarded-User $remote_user;
     proxy_set_header            X-Url-Scheme $scheme;
     proxy_set_header            X-Host $http_host;
     proxy_set_header            X-Real-IP $remote_addr;
     proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header            Proxy-host $proxy_host;
     proxy_buffering             off;
     proxy_connect_timeout       7200;
     proxy_send_timeout          7200;
     proxy_read_timeout          7200;
     proxy_buffers               8 32k;
     client_max_body_size        1024m;

 Apache virtual host reverse proxy example
 -----------------------------------------
 
 Here is a sample configuration file for Apache using proxy:
 
 .. code-block:: apache
 
     <VirtualHost *:80>
             ServerName kallithea.example.com
 
             <Proxy *>
               # For Apache 2.4 and later:
               Require all granted
 
               # For Apache 2.2 and earlier, instead use:
               # Order allow,deny
               # Allow from all
             </Proxy>
 
             #important !
-            #Directive to properly generate url (clone url) for pylons
+            #Directive to properly generate url (clone url) for Kallithea
             ProxyPreserveHost On
 
             #kallithea instance
             ProxyPass / http://127.0.0.1:5000/
             ProxyPassReverse / http://127.0.0.1:5000/
 
             #to enable https use line below
             #SetEnvIf X-Url-Scheme https HTTPS=1
     </VirtualHost>

 Apache as subdirectory
 ----------------------
 
 Apache subdirectory part:
 
 .. code-block:: apache
 
     <Location /<someprefix> >
       ProxyPass http://127.0.0.1:5000/<someprefix>
       ProxyPassReverse http://127.0.0.1:5000/<someprefix>
       SetEnvIf X-Url-Scheme https HTTPS=1
     </Location>
 
 Besides the regular apache setup you will need to add the following line
 into ``[app:main]`` section of your .ini file::
 
     filter-with = proxy-prefix
 
 Add the following at the end of the .ini file::
 
     [filter:proxy-prefix]
     use = egg:PasteDeploy#prefix
     prefix = /<someprefix>
 
 then change ``<someprefix>`` into your chosen prefix
 
 
 Apache with mod_wsgi
 --------------------
 
 Alternatively, Kallithea can be set up with Apache under mod_wsgi. For
 that, you'll need to:
 
 - Install mod_wsgi. If using a Debian-based distro, you can install
   the package libapache2-mod-wsgi::
 
     aptitude install libapache2-mod-wsgi
 
 - Enable mod_wsgi::
 
     a2enmod wsgi
 
 - Add global Apache configuration to tell mod_wsgi that Python only will be
   used in the WSGI processes and shouldn't be initialized in the Apache
   processes::
 
     WSGIRestrictEmbedded On
 
 - Create a wsgi dispatch script, like the one below. Make sure you
   check that the paths correctly point to where you installed Kallithea
   and its Python Virtual Environment.
 - Enable the ``WSGIScriptAlias`` directive for the WSGI dispatch script,
   as in the following example. Once again, check the paths are
   correctly specified.
 
 Here is a sample excerpt from an Apache Virtual Host configuration file:
 
 .. code-block:: apache
 
     WSGIDaemonProcess kallithea processes=5 threads=1 maximum-requests=100 \
         python-home=/srv/kallithea/venv
     WSGIProcessGroup kallithea
     WSGIScriptAlias / /srv/kallithea/dispatch.wsgi
     WSGIPassAuthorization On
 
 Or if using a dispatcher WSGI script with proper virtualenv activation:
 
 .. code-block:: apache
 
     WSGIDaemonProcess kallithea processes=5 threads=1 maximum-requests=100
     WSGIProcessGroup kallithea
     WSGIScriptAlias / /srv/kallithea/dispatch.wsgi
     WSGIPassAuthorization On
 
 Apache will by default run as a special Apache user, on Linux systems
 usually ``www-data`` or ``apache``. If you need to have the repositories
 directory owned by a different user, use the user and group options to
 WSGIDaemonProcess to set the name of the user and group.
 
 Example WSGI dispatch script:
 
 .. code-block:: python
 
     import os
     os.environ["HGENCODING"] = "UTF-8"
     os.environ['PYTHON_EGG_CACHE'] = '/srv/kallithea/.egg-cache'
 
     # sometimes it's needed to set the current dir
     os.chdir('/srv/kallithea/')
 
     import site
     site.addsitedir("/srv/kallithea/venv/lib/python2.7/site-packages")
 
     ini = '/srv/kallithea/my.ini'
     from paste.script.util.logging_config import fileConfig
     fileConfig(ini)
     from paste.deploy import loadapp
     application = loadapp('config:' + ini)
 
 Or using proper virtualenv activation:
 
 .. code-block:: python
 
     activate_this = '/srv/kallithea/venv/bin/activate_this.py'
     execfile(activate_this, dict(__file__=activate_this))
 
     import os
     os.environ['HOME'] = '/srv/kallithea'
 
     ini = '/srv/kallithea/kallithea.ini'
     from paste.script.util.logging_config import fileConfig
     fileConfig(ini)
     from paste.deploy import loadapp
     application = loadapp('config:' + ini)
 
 
 Other configuration files
 -------------------------
 
 A number of `example init.d scripts`__ can be found in
 the ``init.d`` directory of the Kallithea source.
