pagure/doc/configuration.rst

Configuration
=============

Pagure offers a wide varieties of options that must or can be used to
adjust its behavior.

All of these options can be edited or added to your configuration file.
If you have installed pagure, this configuration file is likely located in
``/etc/pagure/pagure.cfg``. Otherwise, it will depend on your
setup/deployment.


Must options
------------

Here are the options you must set up in order to get pagure running.


SECRET_KEY
~~~~~~~~~~

This configuration key is used by flask to create the session. It should be kept secret
and set as a long and random string.


SALT_EMAIL
~~~~~~~~~~

This configuration key is used to ensure that when sending
notifications to different users, each one of them has a different, unique
and unfakeable ``Reply-To`` header. This header is then used by the milter to find
out if the response received is a real one or a fake/invalid one.


DB_URL
~~~~~~

This configuration key indicates to the framework how and where to connect to the database
server. Pagure uses `SQLAchemy <http://www.sqlalchemy.org/>`_ to connect
to a wide range of database server including MySQL, PostgreSQL, and SQLite.

Examples values:

::

    DB_URL = 'mysql://user:pass@host/db_name'
    DB_URL = 'postgresql://user:pass@host/db_name'
    DB_URL = 'sqlite:////var/tmp/pagure_dev.sqlite'

Defaults to ``sqlite:////var/tmp/pagure_dev.sqlite``


APP_URL
~~~~~~~

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

Defaults to: ``http://localhost.localdomain/``


EMAIL_ERROR
~~~~~~~~~~~

Pagure sends email when it catches an unexpected error (which saves you from
having to monitor the logs regularly; but if you like, the error is still
present in the logs).
This configuration key allows you to specify to which email address to send
these error reports.


GIT_URL_SSH
~~~~~~~~~~~

This configuration key provides the information to the user on how to clone
the git repos hosted on pagure via `SSH <https://en.wikipedia.org/wiki/Secure_Shell>`_.

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

Defaults to: ``'ssh://git@llocalhost.localdomain/'``

.. note:: If you are using a custom setup for your deployment where every
        user has an account on the machine you may want to tweak this URL
        to include the username. If that is the case, you can use
        ``{username}`` in the URL and it will be expanded to the username
        of the user viewing the page when rendered.
        For example: ``'ssh://{username}@pagure.org/'``


GIT_URL_GIT
~~~~~~~~~~~

This configuration key provides the information to the user on how to clone
the git repos hosted on pagure anonymously. This access can be granted via
the ``git://`` or ``http(s)://`` protocols.

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

Defaults to: ``'git://localhost.localdomain/'``


BROKER_URL
~~~~~~~~~~

This configuration key is used to point celery to the broker to use. This
is the broker that is used to communicate between the web application and
its workers.

Defaults to: ``"redis://%s:%d/%d" % (pagure_config["REDIS_HOST"], pagure_config["REDIS_PORT"], pagure_config["REDIS_DB"])``

.. note:: See the :ref:`redis-section` for the ``REDIS_HOST``, ``REDIS_PORT``
          and ``REDIS_DB``configuration keys


Repo Directories
----------------

Each project in pagure has 2 to 4 git repositories, depending on configuration
of the Pagure instance (see below):

- the main repo for the code
- the doc repo showed in the doc server (optional)
- the ticket repo storing the metadata of the tickets (optional)
- the request repo storing the metadata of the pull-requests

There are then another 3 folders: one for specifying the locations of the forks, one
for the remote git repo used for the remotes pull-requests (ie: those coming from
a project not hosted on this instance of pagure), and one for user-uploaded tarballs.


GIT_FOLDER
~~~~~~~~~~

This configuration key points to the folder where the git repos are stored.
For every project, two to four repos are created:

* a repo with source code of the project
* a repo with documentation of the project
  (if ``ENABLE_DOCS`` is ``True``)
* a repo with metadata of tickets opened against the project
  (if ``ENABLE_TICKETS`` is ``True``)
* a repo with metadata of pull requests opened against the project


REMOTE_GIT_FOLDER
~~~~~~~~~~~~~~~~~

This configuration key points to the folder where the remote git repos (ie:
not hosted on pagure) that someone used to open a pull-request against a
project hosted on pagure are stored.


UPLOAD_FOLDER_PATH
~~~~~~~~~~~~~~~~~~

This configuration key points to the folder where user-uploaded tarballs
are stored and served from.


ATTACHMENTS_FOLDER
~~~~~~~~~~~~~~~~~~

This configuration key points to the folder where attachments can be cached
for easier access by the web-server (allowing to not interact with the git
repo having it to serve it).


UPLOAD_FOLDER_URL
~~~~~~~~~~~~~~~~~~

Full URL to where the uploads are available. It is highly recommended for
security reasons that this URL lives on a different domain than the main
application (an entirely different domain, not just a sub-domain).

Defaults to: ``/releases/``, unsafe for production!


.. warning:: both `UPLOAD_FOLDER_PATH` and `UPLOAD_FOLDER_URL` must be
            specified for the upload release feature to work


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.
This may be set to False when testing your application but should always
be set to True in production.

Defaults to: ``False`` for development, must be ``True`` in production with
https.


SESSION_TYPE
~~~~~~~~~~~~

Enables the `flask-session <https://pythonhosted.org/Flask-Session/>`_
extension if set to a value other than ``None``. The ``flask-session``
package needs to be installed and proper
`configuration <https://pythonhosted.org/Flask-Session/#configuration>`_
needs to be included in the Pagure config file.

This is useful when the Pagure server needs to be scaled up to multiple
instances, which requires the flask session keys to be shared between those.
Flask-session allows you to use Redis, Memcached, relational database
or MongoDB for storing shared session keys.


FROM_EMAIL
~~~~~~~~~~

This configuration key specifies the email address used by this pagure instance
when sending emails (notifications).

Defaults to: ``pagure@localhost.localdomain``


DOMAIN_EMAIL_NOTIFICATIONS
~~~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key specifies the domain used by this pagure instance
when sending emails (notifications). More precisely, it is used
when building the ``msg-id`` header of the emails sent.

Defaults to: ``localhost.localdomain``


VIRUS_SCAN_ATTACHMENTS
~~~~~~~~~~~~~~~~~~~~~~

This configuration key configures whether attachments are scanned for viruses on
upload. For more information, see the install.rst guide.

Defaults to: ``False``


GIT_AUTH_BACKEND
^^^^^^^^^^^^^^^^

This configuration key allows specifying which git auth backend to use.

By default pagure provides the following backends:

- `test_auth`: simple debugging backend printing and returning the string ``Called GitAuthTestHelper.generate_acls()``
- `pagure`: Pagure git auth implementation (using keyhelper.py and aclchecker.py) that is used via sshd AuthorizedKeysCommand
- `pagure_authorized_keys`: Pagure git auth implementation that writes to authorized_keys file

Defaults to: ``pagure_authorized_keys``


Configure Pagure Auth
---------------------

Pagure offers a simple, but extensible internal authentication mechanism
for Git repositories. It relies on `SSH <https://en.wikipedia.org/wiki/Secure_Shell>`_
for authentication. In other words, SSH lets you in and Pagure checks if
you are allowed to do what you are trying to do once you are inside.

This authentication mechanism uses ``keyhelper.py`` and ``aclchecker.py`` to
check the Pagure database for user registered SSH keys to do the authentication.

The integrated authentication mechanism has two modes of operation: one
where it is configured as the ``AuthorizedKeysCommand`` for the SSH user (preferred)
and one where it is configured to manage the ``authorized_keys`` file for
the SSH user.

In the preferred mode, when you attempt to do an action with a remote Git repo
over SSH (e.g. ``git clone ssh://git@localhost.localdomain/repository.git``),
the SSH server will ask Pagure to validate the SSH user key. This has the
advantage of performance (no racey and slow file I/O) but has the disadvantage
of requiring changes to the system's ``sshd_config`` file to use it.

To use this variant, set the following in ``pagure.cfg``:

::

    GIT_AUTH_BACKEND = "pagure"

    SSH_KEYS_USERNAME_EXPECT = "git"

    SSH_COMMAND = ([
        "/usr/bin/%(cmd)s",
        "/srv/git/repositories/%(reponame)s",
    ], {"GL_USER": "%(username)s"})


Setting the following in ``/etc/ssh/sshd_config`` is also required:

::

    Match User git
        AuthorizedKeysCommand /usr/libexec/pagure/keyhelper.py "%u" "%h" "%t" "%f"
        AuthorizedKeysCommandUser git


If you do not have the ability to modify the sshd configuration to set up
the ``pagure`` backend, then you need to use the ``pagure_authorized_keys``
alternative backend. This backend will write to the git user's  ``authorized_keys``
file instead. This is slower than the preferred mode and also has the
disadvantage of making it impossible to scale to multiple Pagure frontend
instances on top of a shared Git storage without causing races and triggering
inconsistencies. It also adds to the I/O contention on a heavily used system,
but for most smaller setups with few users, the trade-off is not noticeable.

To use this variant, enable the ``pagure_authorized_keys_worker`` service and
set the following to ``pagure.cfg``:

::

    SSH_FOLDER = "/srv/git/.ssh"

    GIT_AUTH_BACKEND = "pagure_authorized_keys"

    SSH_COMMAND = ([
        "/usr/bin/%(cmd)s",
        "/srv/git/repositories/%(reponame)s",
    ], {"GL_USER": "%(username)s"})


EventSource options
-------------------

EVENTSOURCE_SOURCE
~~~~~~~~~~~~~~~~~~

This configuration key indicates the URL at which the EventSource server is
available. If not defined, pagure will behave as if there are no EventSource
server running.


EVENTSOURCE_PORT
~~~~~~~~~~~~~~~~

This configuration key indicates the port at which the EventSource server is
running.

.. note:: The EventSource server requires a redis server (see ``Redis options``
         below)


Web-hooks notifications
-----------------------

WEBHOOK
~~~~~~~

This configuration key allows turning on or off web-hooks notifications for
this pagure instance.

Defaults to: ``False``.

.. note:: The Web-hooks server requires a redis server (see ``Redis options``
         below)


.. _redis-section:


Redis options
-------------

REDIS_HOST
~~~~~~~~~~

This configuration key indicates the host at which the `redis <http://redis.io/>`_
server is running.

Defaults to: ``0.0.0.0``.

REDIS_PORT
~~~~~~~~~~

This configuration key indicates the port at which the redis server can be
contacted.

Defaults to: ``6379``.

REDIS_DB
~~~~~~~~

This configuration key indicates the name of the redis database to use for
communicating with the EventSource server.

Defaults to: ``0``.


Authentication options
----------------------

ADMIN_GROUP
~~~~~~~~~~~

List of groups, either local or remote (if the openid server used supports the
group extension), that are the site admins. These admins can regenerate the
ssh key files, and the hook-token for every project
as well as manage users and groups.


PAGURE_ADMIN_USERS
~~~~~~~~~~~~~~~~~~

List of local users that are the site admins. These admins have the same rights as
the users in the admin groups listed above as well as admin rights to
all projects hosted on this pagure instance.


Celery Queue options
--------------------

In order to help prioritize between tasks having a direct impact on the user
experience and tasks needed to be run on the background but not directly
impacting the users, we have split the generic tasks triggered by the web
application into three possible queues: Fast, Medium, Slow.
If none of these options are set, a single queue will be used for all tasks.

FAST_CELERY_QUEUE
~~~~~~~~~~~~~~~~~

This configuration key can be used to specify a dedicated queue for tasks that
are triggered by the web frontend and need to be processed quickly for the
best user experience.

This will be used for tasks such as creating a new project, forking or
merging a pull-request.

Defaults to: ``None``.

MEDIUM_CELERY_QUEUE
~~~~~~~~~~~~~~~~~~~

This configuration key can be used to specify a dedicated queue for tasks that
are triggered by the web frontend and need to be processed but aren't critical
for the best user experience.

This will be used for tasks such as updating a file in a git repository.

Defaults to: ``None``.

SLOW_CELERY_QUEUE
~~~~~~~~~~~~~~~~~

This configuration key can be used to specify a dedicated queue for tasks that
are triggered by the web frontend, are slow and do not impact the user
experience in the user interface.

This will be used for tasks such as updating the ticket git repo based on
the content posted in the user interface.

Defaults to: ``None``.


Stomp Options
-------------

Pagure integration with Stomp allows you to emit messages to any
stomp-compliant message bus.

STOMP_NOTIFICATIONS
~~~~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off notifications via
`stomp protocol <https://stomp.github.io/>`_. All other stomp-related
settings don't need to be present if this is set to ``False``.

Defaults to: ``False``.

STOMP_BROKERS
~~~~~~~~~~~~~

List of 2-tuples with broker domain names and ports. For example
``[('primary.msg.bus.com', 6543), ('backup.msg.bus.com`, 6543)]``.

STOMP_HIERARCHY
~~~~~~~~~~~~~~~

Base name of the hierarchy to emit messages to. For example
``/queue/some.hierarchy.``. Note that this **must** end with
a dot. Pagure will append queue names such as ``project.new``
to this value, resulting in queue names being e.g.
``/queue/some.hierarchy.project.new``.

STOMP_SSL
~~~~~~~~~

Whether or not to use SSL when connecting to message brokers.

Defaults to: ``False``.

STOMP_KEY_FILE
~~~~~~~~~~~~~~

Absolute path to key file for SSL connection. Only required if
``STOMP_SSL`` is set to ``True``.

STOMP_CERT_FILE
~~~~~~~~~~~~~~~

Absolute path to certificate file for SSL connection. Only required if
``STOMP_SSL`` is set to ``True``.

STOMP_CREDS_PASSWORD
~~~~~~~~~~~~~~~~~~~~

Password for decoding ``STOMP_CERT_FILE`` and ``STOMP_KEY_FILE``. Only
required if ``STOMP_SSL`` is set to ``True`` and credentials files are
password-encoded.

ALWAYS_STOMP_ON_COMMITS
~~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to enforce `stomp <https://stomp.github.io/>`_
notifications on commits made on all projects in a pagure instance.

Defaults to: ``False``.


API token ACLs
--------------

ACLS
~~~~

This configuration key lists all the ACLs that can be associated with an API
token with a short description of what the ACL allows one to do.
This key it not really meant to be changed unless you really know what you
are doing.

USER_ACLS
~~~~~~~~~

This configuration key can be used to list which of the ACLs listed in ``ACLS``
can be associated with an API token of a project in the (web) user interface.

Use this configuration key in combination with ``ADMIN_API_ACLS`` to disable
certain ACLs for users while allowing admins to generate keys with them.

Defaults to: ``[key for key in ACLS.keys() if key != 'generate_acls_project']``
    (ie: all the ACLs in ``ACLS`` except for ``generate_acls_project``)


ADMIN_API_ACLS
~~~~~~~~~~~~~~

This configuration key can be used to list which of the ACLs listed in ``ACLS``
can be generated by the ``pagure-admin`` CLI tool by admins.

Defaults to: ``['issue_comment', 'issue_create', 'issue_change_status', 'pull_request_flag', 'pull_request_comment', 'pull_request_merge', 'generate_acls_project', 'commit_flag', 'create_branch']``


CROSS_PROJECT_ACLS
~~~~~~~~~~~~~~~~~~

This configuration key can be used to list which of the ACLs listed in ``ACLS``
can be associated with a project-less API token in the (web) user interface.
These project-less API tokens can be generated in the user's settings page
and allows action in multiple projects instead of being restricted to a
specific one.

Defaults to: ``['create_project', 'fork_project', 'modify_project']``


Optional options
----------------

Theming
~~~~~~~

THEME
^^^^^

This configuration key allows you to specify the theme to be used. The
string specified is the name of the theme directory in ``pagure/themes/``

For more information about theming see the :doc:`usage/theming`

Default options:

- ``chameleon``  The OpenSUSE theme for pagure
- ``default``  The default theme for pagure
- ``pagureio``  The theme used at https://pagure.io
- ``srcfpo``  The theme used at https://src.fedoraproject.org

Defaults to: ``default``


Git repository templates
~~~~~~~~~~~~~~~~~~~~~~~~

PROJECT_TEMPLATE_PATH
^^^^^^^^^^^^^^^^^^^^^

This configuration key allows you to specify the path to a git repository
to use as a template when creating new repository for new projects.
This template will not be used for forks nor any of the git repository but
the one used for the sources (ie: it will not be used for the tickets,
requests or docs repositories).

FORK_TEMPLATE_PATH
^^^^^^^^^^^^^^^^^^

This configuration key allows you to specify the path to a git repository
to use as a template when creating new repository for new forks.
This template will not be used for any of the git repository but
the one used for the sources of forks (ie: it will not be used for the
tickets, requests or docs repositories).


SSH_KEYS
~~~~~~~~

It is a good practice to publish the fingerprint and public SSH key of a
server you provide access to.
Pagure offers the possibility to expose this information based on the values
set in the configuration file, in the ``SSH_KEYS`` configuration key.

See the `SSH hostkeys/Fingerprints page on pagure.io <https://pagure.io/ssh_info>`_.

.. warning: The format is important

    SSH_KEYS = {'RSA': {'fingerprint': '<foo>', 'pubkey': '<bar>'}}

Where `<foo>` and `<bar>` must be replaced by your values.


CSP_HEADERS
~~~~~~~~~~~

Content Security Policy (CSP) is a computer security standard introduced to
prevent cross-site scripting (XSS), clickjacking and other code injection
attacks resulting from execution of malicious content in the trusted web page
context

Source: https://en.wikipedia.org/wiki/Content_Security_Policy


Defaults to:

::

    CSP_HEADERS = (
        "default-src 'self' https:; "
        "script-src 'self' 'nonce-{nonce}'; "
        "style-src 'self' 'nonce-{nonce}'"
    )

Where ``{nonce}`` is dynamically set by pagure.


LOGGING_GIT_HOOKS
~~~~~~~~~~~~~~~~~

This configuration key allows to have a different logging configuration for the
web application and the git hooks.

If un-specified (default), the logging configuration used by the git hooks will
be the same as the one for the web application (i.e.: defined in ``LOGGING`` here
below).

Defaults to: ``None``.


LOGGING
~~~~~~~

This configuration key allows you to set up the logging of the application.
It relies on the standard `python logging module
<https://docs.python.org/2/library/logging.html>`_.

The default value is:

::

   LOGGING = {
        "version": 1,
        "disable_existing_loggers": False,
        "formatters": {
            "standard": {
                "format": "%(asctime)s [%(levelname)s] %(name)s: %(message)s"
            },
            "email_format": {"format": MSG_FORMAT},
        },
        "filters": {"myfilter": {"()": ContextInjector}},
        "handlers": {
            "console": {
                "formatter": "standard",
                "class": "logging.StreamHandler",
                "stream": "ext://sys.stdout",
            },
            "auth_handler": {
                "formatter": "standard",
                "class": "logging.StreamHandler",
                "stream": "ext://sys.stdout",
            },
            "email": {
                "level": "ERROR",
                "formatter": "email_format",
                "class": "logging.handlers.SMTPHandler",
                "mailhost": "localhost",
                "fromaddr": "pagure@localhost",
                "toaddrs": "root@localhost",
                "subject": "ERROR on pagure",
                "filters": ["myfilter"],
            },
        },
        # The root logger configuration; this is a catch-all configuration
        # that applies to all log messages not handled by a different logger
        "root": {"level": "INFO", "handlers": ["console"]},
        "loggers": {
            "pagure": {
                "handlers": ["console"],
                "level": "DEBUG",
                "propagate": True,
            },
            "pagure_auth": {
                "handlers": ["auth_handler"],
                "level": "DEBUG",
                "propagate": False,
            },
            "flask": {
                "handlers": ["console"],
                "level": "INFO",
                "propagate": False,
            },
            "sqlalchemy": {
                "handlers": ["console"],
                "level": "WARN",
                "propagate": False,
            },
            "binaryornot": {
                "handlers": ["console"],
                "level": "WARN",
                "propagate": True,
            },
            "MARKDOWN": {
                "handlers": ["console"],
                "level": "WARN",
                "propagate": True,
            },
            "PIL": {"handlers": ["console"], "level": "WARN", "propagate": True},
            "chardet": {
                "handlers": ["console"],
                "level": "WARN",
                "propagate": True,
            },
            "pagure.lib.encoding_utils": {
                "handlers": ["console"],
                "level": "WARN",
                "propagate": False,
            },
        },
    }

.. note:: as you can see there is an ``email`` handler defined. It's not used
    anywhere by default but you can use it to get report of errors by email
    and thus monitor your pagure instance.
    To do this the easiest is to set, on the ``root`` logger:
    ::

        'handlers': ['console', 'email'],

.. note:: The ``pagure_auth`` logger is a special one logging all activities
    regarding read/write access to git repositories. It will be a pretty
    important log for auditing if needed.
    You can separate this log into its own file if you like by using the
    following handler:
    ::

        "auth_handler": {
            "formatter": "standard",
            "class": "logging.handlers.TimedRotatingFileHandler",
            "filename": "/var/log/pagure/pagure_auth.log",
            "backupCount": 10,
            "when": "midnight",
            "utc": True,
        },

    This snippet will automatically make the logs rotate at midnight each day,
    keep the logs for 10 days and use UTC as timezone for the logs. Depending on
    how your pagure instance is set-up, you may have to tweak the filesystem
    permissions on the folder and file so the rotation works properly.


ITEM_PER_PAGE
~~~~~~~~~~~~~

This configuration key allows you to configure the length of a page by
setting the number of items on the page. Items can be commits, users, groups,
or projects for example.

Defaults to: ``50``.


PR_TARGET_MATCHING_BRANCH
~~~~~~~~~~~~~~~~~~~~~~~~~

If set to ``True``, the default target branch for all pull requests in UI
is the branch that is longest substring of the branch that the pull request
is created from. For example, a ``mybranch`` branch in original repo will
be the default target of a pull request from branch ``mybranch-feature-1``
in a fork when opening a new pull request. If this is set to ``False``,
the default branch of the repo will be the default target of all pull requests.

Defaults to: ``False``.


SSH_ACCESS_GROUPS
~~~~~~~~~~~~~~~~~

Some instances of pagure are deployed in such a way that only the members of
certain groups are allowed to commit via ssh. This configuration key allows
to specify which groups have commit access and thus let pagure hide the ssh
URL from the drop-down "Clone" menu for all the person who are not in one of
these groups.
If this configuration key is not defined or left empty, it is assume that there
is no such group restriction and everyone can commit via ssh (default behavior).


Defaults to: ``[]``


SMTP configuration
~~~~~~~~~~~~~~~~~~

SMTP_SERVER
^^^^^^^^^^^

This configuration key specifies the SMTP server to use when
sending emails.

Defaults to: ``localhost``.

See also the SMTP_STARTTLS section.


SMTP_PORT
^^^^^^^^^

This configuration key specifies the SMTP server port.

SMTP by default uses TCP port 25. The protocol for mail submission is
the same, but uses port 587.
SMTP connections secured by SSL, known as SMTPS, default to port 465
(nonstandard, but sometimes used for legacy reasons).

Defaults to: ``25``


SMTP_SSL
^^^^^^^^

This configuration key specifies whether the SMTP connections
should be secured over SSL.

Defaults to: ``False``


SMTP_STARTTLS
^^^^^^^^^^^^^

This configuration key specifies instructs pagure to starts connecting to
the SMTP server via a `starttls` command.

When enabling STARTTLS in conjunction with a local smtp server, you should
replace ``localhost`` with a host name that is included in the server's
certificate. If the server only relays messages originating from ``localhost``,
then you should also ensure that the above host name resolves to the same
tcp address as ``localhost``, for instance by adding an appropriate record
to */etc/hosts*.

Defaults to: ``False``


SMTP_KEYFILE
^^^^^^^^^^^^

This configuration key allows to specify a key file to be used in the
`starttls` command when connecting to the smtp server.

Defaults to: ``None``


SMTP_CERTFILE
^^^^^^^^^^^^^

This configuration key allows to specify a certificate file to be used in
the `starttls` command when connecting to the smtp server.

Defaults to: ``None``


SMTP_USERNAME
^^^^^^^^^^^^^

This configuration key allows usage of SMTP with auth.

Note: Specify SMTP_USERNAME and SMTP_PASSWORD for using SMTP auth

Defaults to: ``None``


SMTP_PASSWORD
^^^^^^^^^^^^^

This configuration key allows usage of SMTP with auth.

Note: Specify SMTP_USERNAME and SMTP_PASSWORD for using SMTP auth

Defaults to: ``None``


SHORT_LENGTH
~~~~~~~~~~~~

This configuration key specifies the length of the commit ids or
file hex displayed in the user interface.

Defaults to: ``6``.


BLACKLISTED_PROJECTS
~~~~~~~~~~~~~~~~~~~~

This configuration key specifies a list of project names that are forbidden.
This list is used for example to avoid conflicts at the URL level between the
static files located under ``/static/`` and a project that would be named
``static`` and thus be located at ``/static``.

Defaults to:

::

    [
        'static', 'pv', 'releases', 'new', 'api', 'settings',
        'logout', 'login', 'users', 'groups', 'about'
    ]


CHECK_SESSION_IP
~~~~~~~~~~~~~~~~

This configuration key specifies whether to check the user's IP
address when retrieving its session. This makes things more secure but
under certain setups it might not work (for example if there
are proxies in front of the application).

Defaults to: ``True``.


PAGURE_AUTH
~~~~~~~~~~~~

This configuration key specifies which authentication method to use.
Valid options are ``fas``, ``openid``, ``oidc``, or ``local``.

* ``fas`` uses the Fedora Account System `FAS <https://accounts.fedoraproject.org>`
  to provide user authentication and enforces that users sign the FPCA.

* ``openid`` uses OpenID authentication.  Any provider may be used by
  changing the FAS_OPENID_ENDPOINT configuration key.  By default
  FAS (without FPCA) will be used.

* ``oidc`` enables OpenID Connect using any provider.  This provider requires
  the configuration options starting with ``OIDC_`` (see below) to be provided.

* ``local`` causes pagure to use the local pagure database for user management.
  User registration can be disabled with the ALLOW_USER_REGISTRATION configuration key.

Defaults to: ``local``.


OIDC Settings
~~~~~~~~~~~~~

.. note:: Pagure uses `flask-oidc <https://github.com/puiterwijk/flask-oidc/>`_
   to support OIDC authentication. This extension has a `number of configuration
   keys <http://flask-oidc.readthedocs.io/en/latest/#settings-reference>`_
   that may be useful depending on your set-up


OIDC_CLIENT_SECRETS
^^^^^^^^^^^^^^^^^^^

Provide a path to client secrets file on local filesystem. This file can be
obtained from your OpenID Connect identity provider. Note that some providers
don't fill in ``userinfo_uri``. If that is the case, you need to add it to
the secrets file manually.

OIDC_ID_TOKEN_COOKIE_SECURE
^^^^^^^^^^^^^^^^^^^^^^^^^^^

When this is set to True, the cookie with OpenID Connect Token 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.
This may be set to False when testing your application but should always
be set to True in production.

Defaults to: ``True`` for production with https, can be set to ``False`` for
convenient development.

OIDC_SCOPES
^^^^^^^^^^^

List of `OpenID Connect scopes http://openid.net/specs/openid-connect-core-1_0.html#ScopeClaims`
to request from identity provider.

OIDC_PAGURE_EMAIL
^^^^^^^^^^^^^^^^^

Name of key of user's email in userinfo JSON returned by identity provider.

OIDC_PAGURE_FULLNAME
^^^^^^^^^^^^^^^^^^^^

Name of key of user's full name in userinfo JSON returned by identity provider.

OIDC_PAGURE_USERNAME
^^^^^^^^^^^^^^^^^^^^

Name of key of user's preferred username in userinfo JSON returned by identity
provider.

OIDC_PAGURE_SSH_KEY
^^^^^^^^^^^^^^^^^^^

Name of key of user's ssh key in userinfo JSON returned by identity provider.

OIDC_PAGURE_GROUPS
^^^^^^^^^^^^^^^^^^

Name of key of user's groups in userinfo JSON returned by identity provider.

OIDC_PAGURE_USERNAME_FALLBACK
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This specifies fallback for getting username assuming ``OIDC_PAGURE_USERNAME``
is empty - can be ``email`` (to use the part before ``@``) or ``sub``
(IdP-specific user id, can be a nickname, email or a numeric ID
depending on identity provider).


IP_ALLOWED_INTERNAL
~~~~~~~~~~~~~~~~~~~

This configuration key specifies which IP addresses are allowed
to access the internal API endpoint. These endpoints are accessed by the
milters for example and allow performing actions in the name of someone else
which is sensitive, thus the origin of the request using
these endpoints is validated.

Defaults to: ``['127.0.0.1', 'localhost', '::1']``.


MAX_CONTENT_LENGTH
~~~~~~~~~~~~~~~~~~

This configuration key specifies the maximum file size allowed when
uploading content to pagure (for example, screenshots to a ticket).

Defaults to: ``4 * 1024 * 1024`` which corresponds to 4 megabytes.


ENABLE_TICKETS
~~~~~~~~~~~~~~

This configuration key activates or deactivates the ticketing system
for all the projects hosted on this pagure instance.

Defaults to: ``True``


ENABLE_TICKETS_NAMESPACE
~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to restrict the namespace in which the ticketing
system is enabled.
So if your pagure instance has ``ENABLE_TICKETS`` as ``True`` and sets
``ENABLE_TICKETS_NAMESPACE`` to ``['tests', 'infra']`` only the projects opened
in these two namespaces will have the ticketing system enabled. All the other
namespaces will not.


Defaults to: ``[]``


ENABLE_DOCS
~~~~~~~~~~~

This configuration key activates or deactivates creation of git repos
for documentation for all the projects hosted on this pagure instance.

Defaults to: ``True``


ENABLE_NEW_PROJECTS
~~~~~~~~~~~~~~~~~~~

This configuration key permits or forbids creation of new projects via
the user interface and the API of this pagure instance.

Defaults to: ``True``


ENABLE_UI_NEW_PROJECTS
~~~~~~~~~~~~~~~~~~~~~~

This configuration key permits or forbids creation of new projects via
the user interface (only) of this pagure instance. It allows forbidding
to create new project in the user interface while letting a set of trusted
person to create projects via the API granted they have the API token with
the corresponding ACL.

Defaults to: ``True``


RESTRICT_CREATE_BY_OIDC_GROUP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key, when defined, only allows users that are a member of the group defined
the ability to create new projects and groups.

Defaults to: ``None``


RESTRICT_CREATE_BY_OIDC_GROUP_COUNT
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key, when defined, only allows users that are a member of the group defined
by RESTRICT_CREATE_BY_OIDC_GROUP and a member of at least the number of groups defined by this
key the ability to create new projects.

Defaults to: 0


ENABLE_DEL_PROJECTS
~~~~~~~~~~~~~~~~~~~

This configuration key permits or forbids deletion of projects via
the user interface of this pagure instance.

Defaults to: ``True``


ENABLE_DEL_FORKS
~~~~~~~~~~~~~~~~

This configuration key permits or forbids deletion of forks via
the user interface of this pagure instance.

Defaults to: ``ENABLE_DEL_PROJECTS``


GIT_HOOK_DB_RO
~~~~~~~~~~~~~~

This configuration key specifies if the git hook have a read-only (RO) access
to the database or not.
Some pagure deployment provide an actual shell account on the host and thus the
git hook called upon git push are executed under that account. If the user
manages to by-pass git and is able to access the configuration file, they could
have access to "private" information. So in those deployments the git hooks
have a specific configuration file with a database access that is read-only,
making pagure behave differently in those situations.

Defaults to: ``False``


EMAIL_SEND
~~~~~~~~~~

This configuration key enables or disables all email notifications for
this pagure instance. This can be useful to turn off when developing on
pagure, or for test or pre-production instances.

Defaults to: ``False``.

.. note::
    This does not disable emails to the email address set in ``EMAIL_ERROR``.


FEDMSG_NOTIFICATIONS
~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off notifications via `fedmsg
<https://fedmsg.readthedocs.io/>`_.

Defaults to: ``False``.


FEDORA_MESSAGING_NOTIFICATIONS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off sending notifications via
`fedora-messaging <https://fedora-messaging.readthedocs.io/en/stable/>`_.

Defaults to: ``False``.


ALWAYS_FEDMSG_ON_COMMITS
~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to enforce `fedmsg <https://fedmsg.readthedocs.io/>`_
notifications on commits made on all projects in a pagure instance.

Defaults to: ``True``.


ALLOW_DELETE_BRANCH
~~~~~~~~~~~~~~~~~~~

This configuration keys enables or disables allowing users to delete git
branches from the user interface. In sensible pagure instance you may
want to turn this off.

Defaults to: ``True``.


ALLOW_ADMIN_IGNORE_EXISTING_REPOS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This enables a checkbox "Ignore existing repos" for admins when creating a new
project. When this is checkbox is checked, existing repositories will not cause
project creation to fail.
This could be used to assume responsibility of existing repositories.

Defaults to: ``False``.


USERS_IGNORE_EXISTING_REPOS
~~~~~~~~~~~~~~~~~~~~~~~~~~~

List of users who can al create a project while ignoring existing repositories.

Defaults to: ``[]``.


LOCAL_SSH_KEY
~~~~~~~~~~~~~

This configuration key can be used to let pagure administrate the user's ssh keys
or have a third party tool do it for you.
In most cases, it will be fine to let pagure handle it.

Defaults to ``True``.


DEPLOY_KEY
~~~~~~~~~~

This configuration key can be used to disable the deploy keys feature of an
entire pagure instance. This feature enable to add extra public ssh keys
that a third party could use to push to a project.

Defaults to ``True``.


OLD_VIEW_COMMIT_ENABLED
~~~~~~~~~~~~~~~~~~~~~~~

In version 1.3, pagure changed its URL scheme to view the commit of a
project in order to add support for pseudo-namespaced projects.

For pagure instances older than 1.3, who care about backward compatibility,
we added an endpoint ``view_commit_old`` that brings URL backward
compatibility for URLs using the complete git hash (the 40 characters).
For URLs using a shorter hash, the URLs will remain broken.

This configuration key enables or disables this backward compatibility
which is useful for pagure instances running since before 1.3 but is not
for newer instances.

Defaults to: ``False``.


DISABLE_REMOTE_PR
~~~~~~~~~~~~~~~~~

In some pagure deployments remote pull requests need to be disabled
due to legal / policy reasons.

Defaults to: ``False``.


PAGURE_CI_SERVICES
~~~~~~~~~~~~~~~~~~

Pagure can be configure to integrate results of a Continuous Integration (CI)
service to pull-requests open against a project.

To enable this integration, follow the documentation on how to install
pagure-ci and set this configuration key to ``['jenkins']`` (Jenkins being
the only CI service supported at the moment).

Defaults to: ``None``.

.. warning:: Requires `Redis` to be configured and running.


INSTANCE_NAME
~~~~~~~~~~~~~

This allows giving a name to this running instance of pagure. The name is
then used in the welcome screen shown upon first login.

Defaults to: ``Pagure``

.. note: the welcome screen currently does not work with the `local`
         authentication.

ADMIN_EMAIL
~~~~~~~~~~~

This configuration key allows you to change the default administrator email
which is displayed on the "about" page. It can also be used elsewhere.

Defaults to: ``root@localhost.localdomain``


USER_NAMESPACE
~~~~~~~~~~~~~~

This configuration key can be used to enforce that project are namespaced under
the user's username, behaving in this way in a similar fashion as github.com
or gitlab.com.

Defaults to: ``False``


DOC_APP_URL
~~~~~~~~~~~

This configuration key allows you to specify where the documentation server
is running (preferably in a different domain name entirely).
If not set, the documentation page will show an error message saying that
this pagure instance does not have a documentation server.

Defaults to: ``None``


PRIVATE_PROJECTS
~~~~~~~~~~~~~~~~

This configuration key allows you to host private repositories. These
repositories are visible only to the creator of the repository and to the
users who are given access to the repository. No information is leaked about the
private repository which means redis doesn't have the access to the repository
and even fedmsg doesn't get any notifications.

Defaults to: ``True``


EXCLUDE_GROUP_INDEX
~~~~~~~~~~~~~~~~~~~

This configuration key can be used to hide project an user has access to via
one of the groups listed in this key.

The use-case is the following: the Fedora project is deploying pagure has a
front-end for the git repos of the packages in the distribution, that means
about 17,000 git repositories in pagure. The project has a group of people
that have access to all of these repositories, so when viewing the user's
page of one member of that group, instead of seeing all the project that
this user works on, you can see all the projects hosted in that pagure
instance. Using this configuration key, pagure will hide all the projects
that this user has access to via the specified groups and thus return only
the groups of forks of that users.

Defaults to: ``[]``


TRIGGER_CI
~~~~~~~~~~

A run of pagure-ci can be manually triggered if some key sentences are added
as comment to a pull-request, either manually or via the "Rerun CI" dropdown.
This allows one to re-run a test that failed due to some network outage or other
unexpected issues unrelated to the test suite.

This configuration key can be used to define all the sentences that can be used
to trigger this pagure-ci run. The format is following: ``{"<sentence>":
{"name": "<name of the CI>", "description": "<short description>"}}``

Sentences which have ``None`` as value won't show up in the "Rerun CI"
dropdown. Additionally, it's possible to add a ``requires_project_hook_attr``
key to the dict with data about a sentence. For example, having
``"requires_project_hook_attr": ("ci_hook", "active_pr", True)`` would make
the "Rerun CI" dropdown have a button for this specific CI only if the
project has ``ci_hook`` activated and its ``active_pr`` value is ``True``.

In versions before 5.2, this was a list containing just the sentences.

Defaults to: ``{"pretty please pagure-ci rebuild": {"name": "Default CI",
"description": "Rerun default CI"}}``

.. note:: The sentences defined in this configuration key should be lower
          case only!


FLAG_STATUSES_LABELS
~~~~~~~~~~~~~~~~~~~~

By default, Pagure has ``success``, ``failure``, ``error``, ``pending`` and
``canceled`` statuses of PR and commit flags. This setting allows you to
define a custom mapping of statuses to their respective Bootstrap labels.


FLAG_SUCCESS
~~~~~~~~~~~~

Holds name of PR/commit flag that is considered a success.

Defaults to: ``success``


FLAG_FAILURE
~~~~~~~~~~~~

Holds name of PR/commit flag that is considered a failure.

Defaults to: ``failure``


FLAG_PENDING
~~~~~~~~~~~~

Holds name of PR/commit flag that is considered a pending state.

Defaults to: ``pending``


EXTERNAL_COMMITTER
~~~~~~~~~~~~~~~~~~

The external committer feature is a way to allow members of groups defined
outside pagure (and provided to pagure upon login by the authentication
system) to be consider committers on pagure.

This feature can give access to all the projects on the instance, all but
some or just some.

Defaults to: ``{}``

To give access to all the projects to a group named ``fedora-altarch`` use
a such a structure::

    EXTERNAL_COMMITTER = {
        'fedora-altarch': {}
    }

To give access to all the projects but one (named ``rpms/test``) to a group
named ``provenpackager`` use a such a structure::

    EXTERNAL_COMMITTER = {
        'fedora-altarch': {},
        'provenpackager': {
            'exclude': ['rpms/test']
        }
    }

To give access to just some projects (named ``rpms/test`` and
``modules/test``) to a group named ``testers`` use a such a structure::

    EXTERNAL_COMMITTER = {
        'fedora-altarch': {},
        'provenpackager': {
            'exclude': ['rpms/test']
        },
        'testers': {
            'restrict': ['rpms/test', 'modules/test']
        }
    }


REQUIRED_GROUPS
~~~~~~~~~~~~~~~

The required groups allows one to specify in which group an user must be to be
added to a project with commit or admin access.

Defaults to: ``{}``

Example configuration::

    REQUIRED_GROUPS = {
        'rpms/kernel': ['packager', 'kernel-team'],
        'modules/*': ['module-packager', 'packager'],
        'rpms/*': ['packager'],
        '*': ['contributor'],
    }

With this configuration (evaluated in the provided order):

* only users that are in the groups ``packager`` and ``kernel-team`` will be
  allowed to be added the ``rpms/kernel`` project (where ``rpms`` is the
  namespace and ``kernel`` the project name).

* only users that are in the groups ``module-packager`` and ``packager``
  will be allowed to be added to projects in the ``modules`` namespace.

* only users that are in the group ``packager`` will be allowed to be added
  to projects in the ``rpms`` namespace.

* only users in the ``contributor`` group will be allowed to be added to
  any project on this pagure instance.


GIT_GARBAGE_COLLECT
~~~~~~~~~~~~~~~~~~~

This configuration key allows for explicit running of ``git gc --auto``
after every operation that adds new objects to any git repository -
that is after pushing and merging. The reason for having this functionality
in Pagure is that gc is not guaranteed to be run by git after every
object-adding operation.

The garbage collection run by Pagure will respect git settings, so you
can tweak ``gc.auto`` and ``gc.autoPackLimit`` to your liking
and that will have immediate effect on the task that runs the garbage
collection. These values can be configured system-wide in ``/etc/gitconfig``.
See https://git-scm.com/docs/git-gc#git-gc---auto for more details.

This is especially useful if repositories are stored on NFS (or similar
network storage), where file metadata access is expensive - having unpacked
objects in repositories requires *a lot* of metadata reads.

Defaults to: ``False``


CELERY_CONFIG
~~~~~~~~~~~~~

This configuration key allows you to tweak the configuration of celery for
your needs.
See the documentation about `celery configuration
<http://docs.celeryproject.org/en/latest/userguide/configuration.html>`_ for
more information.

Defaults to: ``{}``


CASE_SENSITIVE
~~~~~~~~~~~~~~

This configuration key can be used to make this pagure instance case sensitive
instead of its default: case-insensitive.

Defaults to: ``False``


PROJECT_NAME_REGEX
~~~~~~~~~~~~~~~~~~

This configuration key can be used to customize the regular expression used to
validate new project name.

Defaults to: ``^[a-zA-z0-9_][a-zA-Z0-9-_]*$``


APPLICATION_ROOT
~~~~~~~~~~~~~~~~

This configuration key is used in the path of the cookie used by pagure.

Defaults to: ``'/'``


ALLOWED_PREFIX
~~~~~~~~~~~~~~

This configuration key can be used to specify a list of allowed namespaces that
will not require creating a group for users to create projects in.

Defaults to: ``[]``


ADMIN_SESSION_LIFETIME
~~~~~~~~~~~~~~~~~~~~~~

This configuration key allows specifying the lifetime of the session during
which the user won't have to log in again for admin actions.
In other words, the maximum time between which an user can access a project's
settings page without a re-login.

Defaults to: ``timedelta(minutes=20)``

where timedelta comes from the python datetime module


BLACKLISTED_GROUPS
~~~~~~~~~~~~~~~~~~

This configuration key can be used to blacklist some group names.

Defaults to: ``['forks', 'group']``


ENABLE_GROUP_MNGT
~~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off managing (ie: creating a
group, adding or removing users in that group) groups in this pagure instance.
If turned off, groups and group members are to be managed outside of pagure
and synced upon login.

Defaults to: ``True``


ENABLE_USER_MNGT
~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off managing users (adding or
removing them from a project) in this pagure instance.
If turned off, users are managed outside of pagure.

Defaults to: ``True``


ALLOW_USER_REGISTRATION
~~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to turn on or off user registration
(that is, the ability for users to create an account) in this pagure instance.
If turned off, user accounts cannot be created through the UI or API.
Currently, this key only applies to pagure instances configured with the ``local``
authentication backend and has no effect with the other authentication backends.

Defaults to: ``True``


SESSION_COOKIE_NAME
~~~~~~~~~~~~~~~~~~~

This configuration key can be used to specify the name of the session cookie used
by pagure.

Defaults to: ``'pagure'``


SHOW_PROJECTS_INDEX
~~~~~~~~~~~~~~~~~~~

This configuration key can be used to specify what is shown in the index page of
logged in users.

Defaults to: ``['repos', 'myrepos', 'myforks']``


EMAIL_ON_WATCHCOMMITS
~~~~~~~~~~~~~~~~~~~~~

By default pagure sends an email to every one watch commits on a project when a
commit is made.
However some pagure instances may be using a different notification mechanism on
commits and thus may not want this feature to double the notifications received.
This configuration key can be used to turn on or off email being sent to people
watching commits on a project upon commits.

Defaults to: ``True``


ALLOW_HTTP_PULL_PUSH
~~~~~~~~~~~~~~~~~~~~

This configuration key controls whether any HTTP access to repositories is provided
via the support for that that's embedded in Pagure.
This provides HTTP pull access via <pagureurl>/<reponame>.git if nothing else
serves this URL.

Defaults to: ``True``


ALLOW_HTTP_PUSH
~~~~~~~~~~~~~~~

This configuration key controls whether pushing is possible via the HTTP interface.
This is disabled by default, as it requires setting up an authentication mechanism
on the webserver that sets REMOTE_USER.

Defaults to: ``False``


MIRROR_SSHKEYS_FOLDER
~~~~~~~~~~~~~~~~~~~~~

This configuration key specificies where pagure should store the ssh keys
generated for the mirroring feature. This folder should be properly backed up
and kept secure.

Defaults to: ``/var/lib/pagure/sshkeys/``


LOG_ALL_COMMITS
~~~~~~~~~~~~~~~

This configuration key will make pagure log all commits pushed to all
branches of all repositories instead of logging only the once that are
pushed to the default branch.

Defaults to: ``False``


DISABLE_MIRROR_IN
~~~~~~~~~~~~~~~~~

This configuration key allows a pagure instance to not support mirroring in
projects (from third party git server).

Defaults to: ``False``


SYNTAX_ALIAS_OVERRIDES
~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to force highlight.js to use a certain logic
on certain files based on their extensions.

It should be a dictionary containing the file extensions as keys and
the highlighting language/category to use as values.

Defaults to: ``{".spec": "specfile", ".patch": "diff"}``


ALLOW_API_UPDATE_GIT_TAGS
~~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key determines whether users are allowed to update
existing git tags via the API.
When set to ``False``, this essentially makes the API ignore whether the
``force`` argument is set or not.

Defaults to: ``True``


PAGURE_PLUGINS_CONFIG
~~~~~~~~~~~~~~~~~~~~~~

This option can be used to specify the configuration file used for loading
plugins. It is not set by default, instead if must be declared explicitly.
Also see the documentation on plugins at :ref:`plugins`.


GIT_DEFAULT_BRANCH
~~~~~~~~~~~~~~~~~~

This configuration key allows to specify the default branch configured upon
project creation. The default branch can be specified by the user upon project
creation but if the user does not specify any branch, this branch name will be
used.

Defaults to: ``None`` (which results in the default branch being ``master``).


PR_WARN_CHARACTERS
~~~~~~~~~~~~~~~~~~

List of characters that triggers a warning to the users when met in a commit of
a pull-request (each commit being made checked).

Defaults to:
::

    set([
        chr(0x202a), chr(0x202b), chr(0x202c), chr(0x202d), chr(0x202e),
        chr(0x2066), chr(0x2067), chr(0x2068), chr(0x2069)
    ])


SSH_KEYS_USERNAME_LOOKUP
~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key is used by the keyhelper script to indicate that the
git username should be used and looked up. Use this if the username that is sent
to ssh is specific for a unique Pagure user (i.e. not using a single "git@" user
for all git operations).


SSH_KEYS_USERNAME_FORBIDDEN
~~~~~~~~~~~~~~~~~~~~~~~~~~~

A list of usernames that are exempted from being verified via the keyhelper.


SSH_KEYS_USERNAME_EXPECT
~~~~~~~~~~~~~~~~~~~~~~~~

This configuration key should contain the username that is used for git if a single
SSH user is used for all git ssh traffic (i.e. "git").


SSH_KEYS_OPTIONS
~~~~~~~~~~~~~~~~

This configuration key provides the options added to keys as they are returned
to sshd, in the same format as AuthorizedKeysFile
(see "AUTHORIZED_KEYS FILE FORMAT" in sshd(8)).


SSH_ADMIN_TOKEN
~~~~~~~~~~~~~~~

If not set to ``None``, ``aclchecker`` and ``keyhelper`` will use this api
admin token to get authorized to internal endpoints that they use. The token
must have the ``internal_access`` ACL.

This is useful when the IP address of sshd service is not predictable
(e.g. because of running in a distributed cloud environment) and so
it's not possible to use the ``IP_ALLOWED_INTERNAL`` address list.

Defaults to: ``None``


SSH_COMMAND
~~~~~~~~~~~

The command to run when aclchecker is in use.



MQTT Options
------------

If approprietly configured pagure supports sending messages to an MQTT
message queue.

Here below are the different configuration options to make it so.

MQTT_NOTIFICATIONS
~~~~~~~~~~~~~~~~~~

Global configuration key to turn on or off the code to send notifications
to an MQTT message queue.

Defaults to: ``False``

MQTT_HOST
~~~~~~~~~

Host name of the MQTT server to send the MQTT notifications to.

Defaults to: ``None``

MQTT_PORT
~~~~~~~~~

Port of the MQTT server to use to send the MQTT notifications to.

Defaults to: ``None``


MQTT_USERNAME
~~~~~~~~~~~~~

Username to authenticate to the MQTT server as.

Defaults to: ``None``


MQTT_PASSWORD
~~~~~~~~~~~~~

Password to authenticate to the MQTT server with.

Defaults to: ``None``


MQTT_CA_CERTS
~~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to point to the CA cert to use.

Defaults to: ``None``


MQTT_CERTFILE
~~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to point to the cert file to use.

Defaults to: ``None``


MQTT_KEYFILE
~~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to point to the key file to use.

Defaults to: ``None``


MQTT_CERT_REQS
~~~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to specify if the CERT is required.

Defaults to: ``ssl.CERT_REQUIRED`` (from python's ssl library)


MQTT_TLS_VERSION
~~~~~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to specify the TLS protocols to support/use.

Defaults to: ``ssl.PROTOCOL_TLSv1_2`` (from python's ssl library)


MQTT_CIPHERS
~~~~~~~~~~~~

When using SSL-based authentication to the MQTT server, use this
configuration key to specify the ciphers.

Defaults to: ``None``


MQTT_TOPIC_PREFIX
~~~~~~~~~~~~~~~~~

This configuration key can be used to specify a prefix to the mqtt messages sent.
This prefix will be added to the topic used by pagure thus allowing the mqtt
admins to specify a parent topic for all pagure-related messages.

Defaults to: ``None``


ALWAYS_MQTT_ON_COMMITS
~~~~~~~~~~~~~~~~~~~~~~

This configuration key can be used to enforce `mqtt <https://mqtt.org/>`_
notifications on commits made on all projects in a pagure instance.

Defaults to: ``False``.


NOGITHOOKS
~~~~~~~~~~

This configuration key should not be touched. It is used in the test suite as a
way to prevent all the git hooks from running (which includes checking if the
user is allowed to push). Using this mechanism we are able to check some
behavior in the test suite that in a deployed pagure instance are happening in
a different process.

**Do not change this option in production**

Defaults to: ``None``.



Deprecated configuration keys
-----------------------------

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

This configuration key used to be use to specify the folder where the forks
are placed. Since the release 2.0 of pagure, it has been deprecated, forks
are now automatically placed in a sub-folder of the folder containing the
mains git repositories (ie ``GIT_FOLDER``).

See the ``UPGRADING.rst`` file for more information about this change and
how to handle it.


UPLOAD_FOLDER
~~~~~~~~~~~~~

This configuration key used to be use to specify where the uploaded releases
are available. It has been replaced by `UPLOAD_FOLDER_PATH` in the release
2.10 of pagure.


DOCS_FOLDER, REQUESTS_FOLDER, TICKETS_FOLDER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

These configuration values were removed. These must have
fixed paths relative to `GIT_FOLDER`. Specifically, they
must occupy subdirectories `docs`, `requests` and `tickets` under `GIT_FOLDER`.
They are now computed automatically based on value of `GIT_FOLDER`.
Usage of docs and tickets can be triggered by setting `ENABLE_DOCS` and
`ENABLE_TICKETS` to `True` (this is the default).
