features:
|
|
- |
|
|
TempURLs now support IP range restrictions. Please see
|
|
https://docs.openstack.org/swift/latest/middleware.html#client-usage
|
|
for more information on how to use this additional restriction.
|
|
|
|
- |
|
|
Add support for multiple root encryption secrets for the trivial
|
|
and KMIP keymasters. This allows operators to rotate encryption
|
|
keys over time without needing to re-encrypt all existing data
|
|
in the cluster. Please see the included sample config files for
|
|
instructions on how to multiple encryption keys.
|
|
|
|
- |
|
|
The object updater now supports two configuration settings:
|
|
"concurrency" and "updater_workers". The latter controls how many
|
|
worker processes are spawned, while the former controls how many
|
|
concurrent container updates are performed by each worker
|
|
process. This should speed the processing of async_pendings.
|
|
|
|
On upgrade, a node configured with concurrency=N will still handle
|
|
async updates N-at-a-time, but will do so using only one process
|
|
instead of N.
|
|
|
|
If you have a config file like this::
|
|
|
|
[object-updater]
|
|
concurrency = <N>
|
|
|
|
and you want to take advantage of faster updates, then do this::
|
|
|
|
[object-updater]
|
|
concurrency = 8 # the default; you can omit this line
|
|
updater_workers = <N>
|
|
|
|
If you want updates to be processed exactly as before, do this::
|
|
|
|
[object-updater]
|
|
concurrency = 1
|
|
updater_workers = <N>
|
|
|
|
- |
|
|
When listing objects in a container in json format, static large
|
|
objects (SLOs) will now include an additional new "slo_etag" key
|
|
that matches the etag returned when requesting the SLO. The
|
|
existing "hash" key remains unchanged as the MD5 of the SLO
|
|
manifest. Text and XML listings are unaffected by this change.
|
|
|
|
- |
|
|
Log deprecation warnings for ``run_pause``. This setting was
|
|
deprecated in Swift 2.4.0 and is replaced by ``interval``.
|
|
It may be removed in a future release.
|
|
|
|
- |
|
|
Object reconstructor logs are now prefixed with information
|
|
about the specific worker process logging the message. This
|
|
makes reading the logs and understanding the messages much simpler.
|
|
|
|
- |
|
|
Lower bounds of dependencies have been updated to reflect what
|
|
is actually tested.
|
|
|
|
- |
|
|
SSYNC replication mode now removes as much of the directory
|
|
structure as possible as soon at it observes that the directory
|
|
is empty. This reduces the work needed for subsequent replication
|
|
passes.
|
|
|
|
- |
|
|
The container-updater now reports zero objects and bytes used for
|
|
child DBs in sharded containers. This prevents double-counting in
|
|
utilization reports.
|
|
|
|
- |
|
|
Add fallocate_reserve to account and container servers. This
|
|
allows disks shared between account/container and object rings to
|
|
avoid getting 100% full. The default value of 1% matches the
|
|
existing default on object servers.
|
|
|
|
- |
|
|
Added an experimental ``swift-ring-composer`` CLI tool to build
|
|
composite rings.
|
|
|
|
- |
|
|
Added an optional ``read_only`` middleware to make an entire cluster
|
|
or individual accounts read only.
|
|
|
|
- |
|
|
Fixed a bug where zero-byte PUTs would not work properly
|
|
with "If-None-Match: \*" conditional requests.
|
|
|
|
- ACLs now work with unicode in user/account names.
|
|
|
|
- COPY now works with unicode account names.
|
|
|
|
- Improved S3 API compatibility.
|
|
|
|
- |
|
|
Lock timeouts in the container updater are now logged at INFO
|
|
level, not ERROR.
|
|
|
|
- Various other minor bug fixes and improvements.
