APP_URL
~~~~~~~

This key indicates the URL at which this pagure instance will be made available.

Defaults to: ``https://pagure.org/``


EMAIL_ERROR

This setting allows you to specify to which email address to send these error

The URL should end with a slash ``/``.

Defaults to: ``'git://pagure.org/'``


GIT_FOLDER
~~~~~~~~~~

This configuration key points to the folder where are stored the git repos
of the projects.

Each project in pagure has 4 git repositories:

- the main repo for the code
- the doc repo showed in the doc server
- the ticket and request repos storing the metadata of the
  tickets/pull-requests

There are then another 2 folders specifying the locations of the forks and
remote git repo used for the remotes pull-requests (ie: pull-request coming
from a project not hosted on pagure).


FORK_FOLDER
~~~~~~~~~~~

This configuration key points to the folder where are stored the git repos
of forks of the projects.


DOCS_FOLDER
~~~~~~~~~~~

This configuration key points to the folder where are stored the git repos
for the documentation of the projects.

against a project hosted on pagure.


SESSION_COOKIE_SECURE
~~~~~~~~~~~~~~~~~~~~~

When this is set to True, the session cookie will only be returned to the
server via ssl (https). If you connect to the server via plain http, the
cookie will not be sent. This prevents sniffing of the cookie contents.

be set to True in production.

Configure Gitolite
------------------

Pagure uses `gitolite <http://gitolite.com/>`_ as an authorization layer.
Gitolite relies on `SSH <https://en.wikipedia.org/wiki/Secure_Shell>`_ for
the authentication. In other words, SSH let you in and gitolite check if you
are allowed to do what you are trying to do once you are inside.


GITOLITE_HOME

This configuration key should point to the home of the user under which
gitolite is ran.

Defaults to: ``3``.


GITOLITE_KEYDIR
~~~~~~~~~~~~~~~

This configuration key points to the folder where gitolite stores and accesses
the public SSH keys of all the user have access to the server.

Since pagure is the user interface, it is pagure that writes down the files
in this directory effectively setting up the users to be able to use gitolite.


GL_RC
~~~~~

This configuration key must point to the file ``gitolite.rc`` used by gitolite
to record who has access to what (ie: who has access to which repo/branch).


GL_BINDIR
~~~~~~~~~

This configuration key indicates the folder in which the gitolite tools can
be found. It can be as simple as ``/usr/bin/`` if the tools have been installed
using a package manager or something like ``/opt/bin/`` for a more custom
install.
