features:
- |
Prefix-based tempurls may now be used to explore staticweb
listings within that prefix. Note that this opens a new ability
to list containers from tempurls, but only if staticweb's
``X-Container-Meta-Web-Listings`` is enabled.
- |
When generating index pages from listings, staticweb now sends an HTML5
doctype. This makes them `PEP 503 `__
compliant, allowing their `continued
use `__ for simple Python
package repositories.
- |
Add basic read support for S3 object locking. This improves
compatibility with an Ansible S3 module. Write support is not
yet implemented, so get-object-lock-configuration will always 404.
- |
Added a ``swift-reload`` command to assist with safely reloading WSGI
servers.
- |
Daemons now send ``STOPPING`` and ``RELOADING`` systemd notifications
when the service is configured with ``Type=notify``.
- |
Added more metrics to the container-server, allowing GET and PUT timings
to be broken out for listings, shard range operations, and container
creation.
- |
Added a counter metric to the proxy server when caching shard ranges.
- |
``swift-account-info`` and ``swift-container-info`` now accept a ``--sync``
flag to show information from the incoming/outgoing sync tables.
- |
Several fixes to prepare for Python 3.12 support. While not yet tested
in the gate, initial manual testing looks promising.
- |
Added support for recent versions of eventlet.
fixes:
- |
S3 API fixes:
* When the ``+segments`` container's storage policy differs from that of
the primary container, completed manifests are now written with the
correct policy in the primary container.
* If there's a conflict deleting the in-progress-upload marker when
completing a multipart-upload, a 503 is now returned to the client,
prompting it to retry.
* Added ``Accept-Ranges: bytes`` to object responses. Range requests
have always been supported; now, that support is properly advertised.
- |
Static large object fixes:
* Fixed a server error when handling conditional GET requests.
* Return an error if the SLO manifest could not be parsed. Previously,
a zero-byte response was returned.
- |
Proxy server fixes:
* Added a new ``swift.proxy_logging_status`` request environment key that
middlewares may use to override the logged status for a request.
* Transaction IDs are included in more error responses.
* The ``recoverable_node_timeout`` option no longer applies to
``X-Newest`` GET requests.
* Improved error-handling in multi-part range responses.
- |
Sharding fixes:
* Prevent resets of a shard range's epoch.
* Cleaned up ``X-Backend-*`` headers in listing responses.
* Reduced the frequency of ``Reclaimable db stuck waiting for shrinking``
messages when a root DB has been deleted but its shards have not been
shrunk away.
* The more-efficient shard range structure from the last release is now
used when fetching ranges from the backend.
* Include more information in shard-replication warnings.
- |
Object server fixes:
* Object POSTs and chunked PUTs are no longer accepted when the target
drive is already past its ``fallocate_reserve``. DELETEs are still
allowed.
* Added the ability to configure cooperative yielding when servicing
GET responses, via the ``cooperative_period`` option. See the example
config for more information.
* Invalid ``hashes.invalid`` entries are now ignored, rather than
causing a complete partition rehash.
- |
Per-service ``auto_create_account_prefix`` configuration options have
been removed. These options were deprecated in favor of ``swift.conf``
configuration in Swift 2.24.0, part of the OpenStack Ussuri release.
- |
Daemons send object updates via the replication network in more cases.
- |
The dark-data object audit watcher now works with sharded containers.
Previously, it would think that all data files were absent from
listings.
