# DEPRECATED:
# Set the image owner to tenant or the authenticated user.
#
# Assign a boolean value to determine the owner of an image. When set to
# True, the owner of the image is the tenant. When set to False, the
# owner of the image will be the authenticated user issuing the request.
# Setting it to False makes the image private to the associated user and
# sharing with other users within the same tenant (or "project")
# requires explicit image sharing via image membership.

# This option is deprecated for removal since Rocky.
# Its value may be silently ignored in the future.
# Reason:
# The non-default setting for this option misaligns Glance with other
# OpenStack services with respect to resource ownership.  Further, surveys
# indicate that this option is not used by operators.  The option will be
# removed early in the 'S' development cycle following the standard OpenStack
# deprecation policy.  As the option is not in wide use, no migration path is
# proposed.

# Allow users to add additional/custom properties to images.
#
# Glance defines a standard set of properties (in its schema) that
# appear on every image. These properties are also known as
# ``base properties``. In addition to these properties, Glance
# allows users to add custom properties to images. These are known
# as ``additional properties``.
#
# By default, this configuration option is set to ``True`` and users
# are allowed to add additional properties. The number of additional
# properties that can be added to an image can be controlled via
# ``image_property_quota`` configuration option.

# Secure hashing algorithm used for computing the 'os_hash_value' property.
#
# This option configures the Glance "multihash", which consists of two
# image properties: the 'os_hash_algo' and the 'os_hash_value'.  The
# 'os_hash_algo' will be populated by the value of this configuration
# option, and the 'os_hash_value' will be populated by the hexdigest computed
# when the algorithm is applied to the uploaded or imported image data.
#
# The value must be a valid secure hash algorithm name recognized by the
# python 'hashlib' library.  You can determine what these are by examining
# the 'hashlib.algorithms_available' data member of the version of the
# library being used in your Glance installation.  For interoperability
# purposes, however, we recommend that you use the set of secure hash
# names supplied by the 'hashlib.algorithms_guaranteed' data member because
# those algorithms are guaranteed to be supported by the 'hashlib' library
# on all platforms.  Thus, any image consumer using 'hashlib' locally should
# be able to verify the 'os_hash_value' of the image.
#
# The default value of 'sha512' is a performant secure hash algorithm.
#
# If this option is misconfigured, any attempts to store image data will fail.
# For that reason, we recommend using the default value.

#     * glance.db.simple.api
#
# If this option is set to ``glance.db.sqlalchemy.api`` then the image
# catalog data is stored in and read from the database via the
# SQLAlchemy Core and ORM APIs.
#
# Setting this option to ``glance.db.registry.api`` will force all
# database access requests to be routed through the Registry service.
# This avoids data access from the Glance API nodes for an added layer
# of security, scalability and manageability.
#
# NOTE: In v2 OpenStack Images API, the registry service is optional.
# In order to use the Registry API in v2, the option
# ``enable_v2_registry`` must be set to ``True``.
#
# Finally, when this configuration option is set to

# The default number of results to return for a request.
#
# Responses to certain API requests, like list images, may return
# multiple items. The number of results returned can be explicitly

# image location is shown under the image property ``direct_url``.
#
# When multiple image locations exist for an image, the best location
# is displayed based on the location strategy indicated by the

#
# NOTES:
#     * Revealing image locations can present a GRAVE SECURITY RISK as

# Its value may be silently ignored in the future.
# Reason: Use of this option, deprecated since Newton, is a security risk and
# will be removed once we figure out a way to satisfy those use cases that
# currently require it.  An earlier announcement that the same functionality can
# be achieved with greater granularity by using policies is incorrect.  You
# cannot work around this option via policy configuration at the present time,

#
# Maximum size of image a user can upload in bytes.
#
# An image upload greater than the size mentioned here would result

#
# NOTES:
#     * This value should only be increased after careful
#       consideration and must be set less than or equal to
#       8 EiB (9223372036854775808).

#
# The default unit for this configuration option is Bytes. However, storage
# units can be specified using case-sensitive literals ``B``, ``KB``, ``MB``,
# ``GB`` and ``TB`` representing Bytes, KiloBytes, MegaBytes, GigaBytes and
# TeraBytes respectively. Note that there should not be any space between the
# value and unit. Value ``0`` signifies no quota enforcement. Negative values
# are invalid and result in errors.
#
# Possible values:

# from the first responsive active location it finds in this list.
#
# This option takes one of two possible values ``location_order``
# and ``store_type``. The default value is ``location_order``,
# which suggests that image data be served by using locations in
# the order they are stored in Glance. The ``store_type`` value
# sets the image location preference based on the order in which

# for providing the essential functions of image-cache like write images to/read
# images from cache, track age and usage of cached images, provide a list of
# cached images, fetch size of the cache, queue images for caching and clean up
# the cache, etc.
#
# The essential functions of a driver are defined in the base class
# ``glance.image_cache.drivers.base.Driver``. All image-cache drivers (existing
# and prospective) must implement this interface. Currently available drivers
# are ``sqlite`` and ``xattr``. These drivers primarily differ in the way they
# store the information about cached images:
#     * The ``sqlite`` driver uses a sqlite database (which sits on every glance
#     node locally) to track the usage of cached images.
#     * The ``xattr`` driver uses the extended attributes of files to store this
#     information. It also requires a filesystem that sets ``atime`` on the

#
# NOTE: This is just a threshold for cache-pruner to act upon. It is NOT a

# on how often the cache-pruner runs and how quickly the cache fills, the image
# cache can far exceed the size specified here very easily. Hence, care must be
# taken to appropriately schedule the cache-pruner and in setting this limit.
#
# Glance caches an image when it is downloaded. Consequently, the size of the
# image cache grows over time as the number of downloads increases. To keep the
# cache size from becoming unmanageable, it is recommended to run the
# cache-pruner as a periodic task. When the cache pruner is kicked off, it
# compares the current size of image cache and triggers a cleanup if the image
# cache grew beyond the size specified here. After the cleanup, the size of

# Base directory for image cache.
#
# This is the location where image data is cached and served out of. All cached
# images are stored directly under this directory. This directory also contains
# three subdirectories, namely, ``incomplete``, ``invalid`` and ``queue``.
#
# The ``incomplete`` subdirectory is the staging area for downloading images. An
# image is first downloaded to this directory. When the image download is
# successful it is moved to the base directory. However, if the download fails,
# the partially downloaded image file is moved to the ``invalid`` subdirectory.
#
# The ``queue``subdirectory is used for queuing images for download. This is
# used primarily by the cache-prefetcher, which can be scheduled as a periodic
# task like cache-pruner and cache-cleaner, to cache images ahead of their
# usage.
# Upon receiving the request to cache an image, Glance touches a file in the
# ``queue`` directory with the image id as the file name. The cache-prefetcher,
# when running, polls for the files in ``queue`` directory and starts
# downloading them in the order they were created. When the download is
# successful, the zero-sized file is deleted from the ``queue`` directory.
# If the download fails, the zero-sized file remains and it'll be retried the

# as ``additional properties``.
#
# By default, this configuration option is set to ``True`` and users

# 'os_hash_algo' will be populated by the value of this configuration
# option, and the 'os_hash_value' will be populated by the hexdigest computed
# when the algorithm is applied to the uploaded or imported image data.
#
# The value must be a valid secure hash algorithm name recognized by the
# python 'hashlib' library.  You can determine what these are by examining
# the 'hashlib.algorithms_available' data member of the version of the
# library being used in your Glance installation.  For interoperability
# purposes, however, we recommend that you use the set of secure hash
# names supplied by the 'hashlib.algorithms_guaranteed' data member because

# Sometimes, due to various reasons, it is possible the download may hang and

# Base directory for image cache.
#
# This is the location where image data is cached and served out of. All cached
# images are stored directly under this directory. This directory also contains
# three subdirectories, namely, ``incomplete``, ``invalid`` and ``queue``.
#
# The ``incomplete`` subdirectory is the staging area for downloading images. An
# image is first downloaded to this directory. When the image download is
# successful it is moved to the base directory. However, if the download fails,
# the partially downloaded image file is moved to the ``invalid`` subdirectory.
#
# The ``queue``subdirectory is used for queuing images for download. This is
# used primarily by the cache-prefetcher, which can be scheduled as a periodic
# task like cache-pruner and cache-cleaner, to cache images ahead of their
# usage.
# Upon receiving the request to cache an image, Glance touches a file in the
# ``queue`` directory with the image id as the file name. The cache-prefetcher,
# when running, polls for the files in ``queue`` directory and starts
# downloading them in the order they were created. When the download is
# successful, the zero-sized file is deleted from the ``queue`` directory.
# If the download fails, the zero-sized file remains and it'll be retried the
# next time cache-prefetcher runs.

# Time in seconds defining the size of the window in which a new
# token may be requested before the current token is due to expire.
#
# Typically, the Swift storage driver fetches a new token upon the
# expiration of the current token to ensure continued access to
# Swift. However, some Swift transactions (like uploading image
# segments) may not recover well if the token expires on the fly.
#
# Hence, by fetching a new token before the current token expiration,
# we make sure that the token does not expire or is close to expiry
# before a transaction is attempted. By default, the Swift storage
# driver requests for a new token 60 seconds or less before the
# current token expiration.
