features:
|
|
- Add checksum to object extended attributes.
|
|
|
|
- |
|
|
Let clients request heartbeats during SLO PUTs by including
|
|
the query parameter ``heartbeat=on``.
|
|
|
|
With heartbeating turned on, the proxy will start its response
|
|
immediately with 202 Accepted then send a single whitespace
|
|
character periodically until the request completes. At that
|
|
point, a final summary chunk will be sent which includes a
|
|
"Response Status" key indicating success or failure and (if
|
|
successful) an "Etag" key indicating the Etag of the resulting
|
|
SLO.
|
|
|
|
- |
|
|
Added support for retrieving the encryption root secret from an
|
|
external key management system. In practice, this is currently limited
|
|
to Barbican.
|
|
|
|
- |
|
|
Move listing formatting out to a new proxy middleware named
|
|
``listing_formats``. ``listing_formats`` should be just right of the
|
|
first proxy-logging middleware, and left of most other
|
|
middlewares. If it is not already present, it will be
|
|
automatically inserted for you.
|
|
|
|
Note: if you have a custom middleware that makes account or
|
|
container listings, it will only receive listings in JSON format.
|
|
|
|
- |
|
|
Log deprecation warning for ``allow_versions`` in the container
|
|
server config. Configure the ``versioned_writes`` middleware in
|
|
the proxy server instead. This option will be ignored in a
|
|
future release.
|
|
|
|
- |
|
|
Replaced ``replication_one_per_device`` by custom count defined by
|
|
``replication_concurrency_per_device``. The original config value
|
|
is deprecated, but continues to function for now. If both values
|
|
are defined, the old ``replication_one_per_device`` is ignored.
|
|
|
|
- |
|
|
Fixed a rare issue where multiple backend timeouts could result
|
|
in bad data being returned to the client.
|
|
|
|
- Cleaned up logged tracebacks when talking to memcached servers.
|
|
|
|
- |
|
|
Account and container replication stats logs now include
|
|
``remote_merges``, the number of times a whole database was sent
|
|
to another node.
|
|
|
|
- |
|
|
Respond 400 Bad Request when Accept headers fail to parse
|
|
instead of returning 406 Not Acceptable.
|
|
|
|
- |
|
|
The ``domain_remap`` middleware now supports the
|
|
``mangle_client_paths`` option. Its default "false" value changes
|
|
``domain_remap`` parsing to stop stripping the ``path_root`` value
|
|
from URL paths. If users depend on this path mangling, operators
|
|
should set ``mangle_client_paths`` to "True" before upgrading.
|
|
|
|
- |
|
|
Remove ``swift-temp-url`` script. The functionality has been in
|
|
swiftclient for a long time and this script has been deprecated
|
|
since 2.10.0.
|
|
|
|
- |
|
|
Removed all ``post_as_copy`` related code and configs. The option
|
|
has been deprecated since 2.13.0.
|
|
|
|
- |
|
|
Fixed XML responses (eg on bulk extractions and SLO upload
|
|
failures) to be more correct. The enclosing "delete" tag was
|
|
removed where it doesn't make sense and replaced with "extract"
|
|
or "upload" depending on the context.
|
|
|
|
- |
|
|
Static Large Object (SLO) manifest may now (again) have zero-byte
|
|
last segments.
|
|
|
|
- |
|
|
Fixed an issue where background consistency daemon child
|
|
processes would deadlock waiting on the same file descriptor.
|
|
|
|
- |
|
|
Removed a race condition where a POST to an SLO could modify the
|
|
X-Static-Large-Object metadata.
|
|
|
|
- |
|
|
Accept a trade off of dispersion for balance in the ring builder
|
|
that will result in getting to balanced rings much more quickly
|
|
in some cases.
|
|
|
|
- |
|
|
Fixed using ``swift-ring-builder set_weight`` with more than one
|
|
device.
|
|
|
|
- |
|
|
When requesting objects, return 404 if a tombstone is found and
|
|
is newer than any data found. Previous behavior was to return
|
|
stale data.
