cli: convert 'gearbox celeryd' into 'kallithea-cli celery-run'

Note:
- '--' is never explicitly present in the arguments when using Click.
  The click parser will take care of '--' as separator between
  dash-dash-arguments and positional arguments, following standard UNIX

 Setup
 =====
 
 
 Preparing front-end
 -------------------
 
 Temporarily, in the current Kallithea version, some extra steps are required to
 build front-end files:
 
 Find the right ``kallithea/public/less`` path with::
 
     python -c "import os, kallithea; print os.path.join(os.path.dirname(os.path.abspath(kallithea.__file__)), 'public', 'less')"
 
 Then run::
 
     npm install
     npm run less
 
 
 Setting up Kallithea
 --------------------
 
 First, you will need to create a Kallithea configuration file. Run the
 following command to do so::
 
     kallithea-cli config-create 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. Extra settings can be specified like::
 
     kallithea-cli config-create my.ini host=8.8.8.8 "[handler_console]" formatter=color_formatter
 
 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::
 
     kallithea-cli db-create -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 ``db-create`` will also prompt you for a username
 and password for the initial admin account which ``db-create`` sets
 up for you.
 
 The ``db-create`` values can also be given on the command line.
 Example::
 
     kallithea-cli db-create -c my.ini --user=nn --password=secret --email=[e-mail] --repos=/srv/repos
 
 The ``db-create`` 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 ``db-create``.
 - 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://[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://whoosh.readthedocs.io/en/latest/
 
 For an incremental index build, run::
 
     kallithea-cli index-create -c my.ini
 
 For a full index rebuild, run::
 
     kallithea-cli index-create -c my.ini --full
 
 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::
 
     kallithea-cli index-create -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/kallithea-cli index-create -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.
 
 
 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.
 
 This is achieved with following three variables in the ini file::
 
     issue_pat = #(\d+)
     issue_server_link = https://issues.example.com/{repo}/issue/\1
     issue_sub =
 
 ``issue_pat`` is the regular expression describing which strings in
 commit messages will be treated as issue references. The expression can/should
 have one or more parenthesized groups that can later be referred to in
 ``issue_server_link`` and ``issue_sub`` (see below). If you prefer, named groups
 can be used instead of simple parenthesized groups.
 
 If the pattern should only match if it is preceded by whitespace, add the
 following string before the actual pattern: ``(?:^|(?<=\s))``.
 If the pattern should only match if it is followed by whitespace, add the
 following string after the actual pattern: ``(?:$|(?=\s))``.
 These expressions use lookbehind and lookahead assertions of the Python regular
 expression module to avoid the whitespace to be part of the actual pattern,
 otherwise the link text will also contain that whitespace.
 
 Matched issue references are replaced with the link specified in
 ``issue_server_link``, in which any backreferences are resolved. Backreferences
 can be ``\1``, ``\2``, ... or for named groups ``\g<groupname>``.
 The special token ``{repo}`` is replaced with the full repository path
 (including repository groups), while token ``{repo_name}`` is replaced with the
 repository name (without repository groups).
 
 The link text is determined by ``issue_sub``, which can be a string containing
 backreferences to the groups specified in ``issue_pat``. If ``issue_sub`` is
 empty, then the text matched by ``issue_pat`` is used verbatim.
 
 The example settings shown above match issues in the format ``#<number>``.
 This will cause the text ``#300`` to be transformed into a link:
 
 .. code-block:: html
 
   <a href="https://issues.example.com/example_repo/issue/300">#300</a>
 
 The following example transforms a text starting with either of 'pullrequest',
 'pull request' or 'PR', followed by an optional space, then a pound character
 (#) and one or more digits, into a link with the text 'PR #' followed by the
 digits::
 
     issue_pat = (pullrequest|pull request|PR) ?#(\d+)
     issue_server_link = https://issues.example.com/\2
     issue_sub = PR #\2
 
 The following example demonstrates how to require whitespace before the issue
 reference in order for it to be recognized, such that the text ``issue#123`` will
 not cause a match, but ``issue #123`` will::
 
     issue_pat = (?:^|(?<=\s))#(\d+)
     issue_server_link = https://issues.example.com/\1
     issue_sub =
 
 If needed, more than one pattern can be specified by appending a unique suffix to
 the variables. For example, also demonstrating the use of named groups::
 
     issue_pat_wiki = wiki-(?P<pagename>\S+)
     issue_server_link_wiki = https://wiki.example.com/\g<pagename>
     issue_sub_wiki = WIKI-\g<pagename>
 
 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>
 
 Refer to the `Python regular expression documentation`_ for more details about
 the supported syntax in ``issue_pat``, ``issue_server_link`` and ``issue_sub``.
 
 
 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.
 
 The Mercurial encoding is configurable as ``hgencoding``. It is similar to
 setting the ``HGENCODING`` environment variable, but will override it.
 
 
 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::
 
-  gearbox celeryd -c my.ini
+  kallithea-cli celery-run -c my.ini
 
 Extra options to the Celery worker can be passed after ``--`` - see ``-- -h``
 for more info.
 
 .. 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.

        }
 
     }

             <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 !

             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_subdirectory:
 
 
 Apache as subdirectory
 ----------------------
 
 Apache subdirectory part:
 
 .. code-block:: apache
 
     <Location /PREFIX >
       ProxyPass http://127.0.0.1:5000/PREFIX
       ProxyPassReverse http://127.0.0.1:5000/PREFIX
       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 = /PREFIX
 
 then change ``PREFIX`` into your chosen prefix
 
 .. _apache_mod_wsgi:
 
 
 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['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)
