Middleware features:
|
|
|
|
* The static large object (SLO) middleware now supports including
|
|
a ``?part-number=<N>`` query parameter to request just part of a
|
|
large object. This may be used to enable efficient parallel
|
|
downloads. For more information, see `the documentation
|
|
<https://docs.openstack.org/swift/latest/overview_large_objects.html#retrieving-a-large-object>`__.
|
|
|
|
* The S3 API middleware now supports the ``?partNumber=<N>`` query
|
|
parameter, enabling parallel downloads.
|
|
|
|
* The KMS keymaster now supports overriding the endpoint returned
|
|
in the Keystone catalog via the ``barbican_endpoint`` configuration
|
|
option. This may be useful in multi-region deployments which have
|
|
multiple endpoints.
|
|
|
|
* The backend ratelimiter now supports dynamic reloading of limits.
|
|
The new configuration options ``backend_ratelimit_conf_path`` and
|
|
``config_reload_interval`` control which file is reloaded and how
|
|
frequently, respectively.
|
|
|
|
* The backend ratelimiter now supports per-method, per-device
|
|
ratelimits. See `etc/backend-ratelimit.conf-sample
|
|
<https://github.com/openstack/swift/blob/master/etc/backend-ratelimit.conf-sample>`__
|
|
for more information.
|
|
|
|
* The account quota middleware now supports object-count quotas
|
|
in addition to byte-count quotas, similar to the container
|
|
quota middleware. For more information, see `the documentation
|
|
<https://docs.openstack.org/swift/latest/middleware.html#module-swift.common.middleware.account_quotas>`__.
|
|
|
|
- |
|
|
Object expiration improvements:
|
|
|
|
* Added per-account and per-container reaping delays. These may be
|
|
used to offer some grace period in which to recover expired objects.
|
|
|
|
* Added a proxy-server configuration option: ``allow_open_expired``.
|
|
This defaults to false; if true, clients may intereact with expired
|
|
objects by including an ``X-Open-Expired: true`` header in GET, HEAD,
|
|
or POST requests.
|
|
|
|
* Expiring object queue entries now include the size of the object to
|
|
be expired in the ``swift_expirer_bytes`` parameter of the queue entry's
|
|
content-type.
|
|
|
|
* Added metrics to count skipped, delayed, and assigned tasks as
|
|
they're enumerated.
|
|
|
|
- |
|
|
S3 API error response reasons are now logged as part of the ``log_info``
|
|
field. This can be especially useful when diagnosing HEAD
|
|
failures, which necessarily have no response body.
|
|
|
|
- |
|
|
Python 3.12 is now supported.
|
|
|
|
- |
|
|
``swift-account-info`` now supports the ``--sync`` option to display the
|
|
contents of the incoming and outgoing sync tables, similar to
|
|
``swift-container-info``.
|
|
|
|
- |
|
|
The ``swift-drive-audit`` tool now works with ISO timestamps in kernel
|
|
logs.
|
|
|
|
upgrade:
|
|
- |
|
|
Dependency update: lxml must be at least 4.2.3.
|
|
|
|
deprecations:
|
|
- |
|
|
Overall account byte quotas should now be set with the
|
|
``X-Account-Quota-Bytes`` header. The ``X-Account-Meta-Quota-Bytes``
|
|
header is now deprecated.
|
|
|
|
fixes:
|
|
- |
|
|
S3 API fixes:
|
|
|
|
* Fixed a server error when using non-ASCII access key IDs.
|
|
|
|
* Fixed several checksum-related error responses to be more AWS-like.
|
|
|
|
- |
|
|
Using an ``X-Remove-Account-Quota-Bytes-Policy-<policy name>`` header
|
|
now removes the per-policy quota, rather than reducing it to zero.
|
|
|
|
- |
|
|
Proxy-server fixes:
|
|
|
|
* Object POSTs now 503 rather than trusting the 404s that might be
|
|
returned from handoffs when primaries are overloaded.
|
|
|
|
* Client disconnects should always be logged within the context of
|
|
the appropriate client request. Previously, there were some cases
|
|
where logging would occur during general garbage collection, leading
|
|
to incorrect or missing transaction IDs in logs.
|
|
|
|
* The proxy-logging middleware now emits timing and transfer stats for
|
|
more requests such as auth requests. These will be labeled ``UNKNOWN``
|
|
rather than ``account``, ``container``, etc.
|
|
|
|
* Fixed a server error when the Swift request path has missing account
|
|
or container components.
|

|
- |
|
|
``EUCLEAN`` errors are better handled on the object server.
|
|
|
|
- |
|
|
The ``swift-recon-cron`` tool now better handles missing directories.
