Sad, but true. Especially because we reuse Repository instances between
threads.

 =====
 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.

 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
  Port                 = 389
  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 : required
     389 for un-encrypted LDAP, 636 for SSL-encrypted LDAP.
 
 .. _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
 
     No encryption
         Plain non encrypted connection
 
     LDAPS connection
         Enable LDAPS connections. It will likely require `Port`_ to be set to
         a different value (standard LDAPS port is 636). When LDAPS is enabled
         then `Certificate Checks`_ is required.
 
     START_TLS on LDAP connection
         START TLS connection
 
 .. _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
     while the other options are susceptible to man-in-the-middle attacks.  SSL
     certificates can be installed to /etc/openldap/cacerts so that the
     DEMAND or HARD options can be used with self-signed certificates or
     certificates that do not have traceable certificates of authority.
 
     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.
 
 .. _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
 
       RewriteEngine On
       RewriteCond %{LA-U:REMOTE_USER} (.+)
       RewriteRule .* - [E=RU:%1]
       RequestHeader set X-Forwarded-User %{RU}e
     </Location>
 
 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;

 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
             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 \
-        threads=4 \
+    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 threads=4
+    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.

 ================================
 Optimizing Kallithea performance
 ================================
 
 When serving a large amount of big repositories, Kallithea can start
 performing slower than expected. Because of the demanding nature of handling large
 amounts of data from version control systems, here are some tips on how to get
 the best performance.
 
 Follow these few steps to improve performance of Kallithea system.
 
 1.  Kallithea is often I/O bound, and hence a fast disk (SSD/SAN) is
     usually more important than a fast CPU.
 
 2. Increase cache
 
     Tweak beaker cache settings in the ini file. The actual effect of that
     is questionable.
 
 3. Switch from SQLite to PostgreSQL or MySQL
 
     SQLite is a good option when having a small load on the system. But due to
     locking issues with SQLite, it is not recommended to use it for larger
     deployments. Switching to MySQL or PostgreSQL will result in an immediate
     performance increase. A tool like SQLAlchemyGrate_ can be used for
     migrating to another database platform.
 
 4. Scale Kallithea horizontally
 
     Scaling horizontally can give huge performance benefits when dealing with
     large amounts of traffic (many users, CI servers, etc.). Kallithea can be
-    scaled horizontally on one (recommended) or multiple machines. In order
-    to scale horizontally you need to do the following:
+    scaled horizontally on one (recommended) or multiple machines.
+
+    It is generally possible to run WSGI applications multithreaded, so that
+    several HTTP requests are served from the same Python process at once. That
+    can in principle give better utilization of internal caches and less
+    process overhead.
+    
+    One danger of running multithreaded is that program execution becomes much
+    more complex; programs must be written to consider all combinations of
+    events and problems might depend on timing and be impossible to reproduce.
+
+    Kallithea can't promise to be thread-safe, just like the embedded Mercurial
+    backend doesn't make any strong promises when used as Kallithea uses it.
+    Instead, we recommend scaling by using multiple server processes.
+
+    Web servers with multiple worker processes (such as ``mod_wsgi`` with the
+    ``WSGIDaemonProcess`` ``processes`` parameter) will work out of the box.
+
+    In order to scale horizontally on multiple machines, you need to do the
+    following:
 
     - Each instance's ``data`` storage needs to be configured to be stored on a
       shared disk storage, preferably together with repositories. This ``data``
       dir contains template caches, sessions, whoosh index and is used for
       task locking (so it is safe across multiple instances). Set the
       ``cache_dir``, ``index_dir``, ``beaker.cache.data_dir``, ``beaker.cache.lock_dir``
       variables in each .ini file to a shared location across Kallithea instances
-    - If celery is used each instance should run a separate Celery instance, but
+    - If using several Celery instances,
       the message broker should be common to all of them (e.g.,  one
       shared RabbitMQ server)
     - Load balance using round robin or IP hash, recommended is writing LB rules
       that will separate regular user traffic from automated processes like CI
       servers or build bots.
 
 5. Serve static files directly from the web server
 
 With the default ``static_files`` ini setting, the Kallithea WSGI application
 will take care of serving the static files found in ``kallithea/public`` from
 the root of the application URL. While doing that, it will currently also
 apply buffering and compression of all the responses it is serving.
 
 The actual serving of the static files is unlikely to be a problem in a
 Kallithea setup. The buffering of responses is more likely to be a problem;
 large responses (clones or pulls) will have to be fully processed and spooled
 to disk or memory before the client will see any response.
 
 To serve static files from the web server, use something like this Apache config
 snippet::
 
         Alias /images/ /srv/kallithea/kallithea/kallithea/public/images/
         Alias /css/ /srv/kallithea/kallithea/kallithea/public/css/
         Alias /js/ /srv/kallithea/kallithea/kallithea/public/js/
         Alias /codemirror/ /srv/kallithea/kallithea/kallithea/public/codemirror/
         Alias /fontello/ /srv/kallithea/kallithea/kallithea/public/fontello/
 
 Then disable serving of static files in the ``.ini`` ``app:main`` section::
 
         static_files = false
 
 If using Kallithea installed as a package, you should be able to find the files
 under site-packages/kallithea, either in your Python installation or in your
 virtualenv. When upgrading, make sure to update the web server configuration
 too if necessary.
