features:
|
|
- |
|
|
Python 3.11 is now supported.
|
|
|
|
- |
|
|
Added the ability for reseller admins to set per-policy account quotas by
|
|
posting metadata of the form ``X-Account-Quota-Bytes-Policy-<policy name>``.
|
|
|
|
- |
|
|
Added a ``keepalive_timeout`` option to the proxy server to limit how long
|
|
to wait for a client to initiate a request, separate from the general
|
|
``client_timeout`` option. Note that this requires eventlet 0.33.4
|
|
(currently unreleased) or later.
|
|
|
|
- |
|
|
Added a ``keep_cache_slo_manifest`` option to the object server to better
|
|
control whether SLO manifests are dropped from the page cache.
|
|
|
|
- |
|
|
WSGI servers now accept a ``--test-config`` option that may be used to
|
|
validate configuration changes before reloading/restarting the server.
|
|
|
|
- |
|
|
Metrics improvements:
|
|
|
|
* Metrics are now emitted for a variety of S3 error responses, in the
|
|
form ``s3api.<status_int>.<error_class>[.<reason>]``
|
|
|
|
* Account and container info metrics now include the response status code
|
|
when backend requests are made.
|
|
|
|
* Added timing metrics to the container sharder for various operations.
|
|
|
|
- |
|
|
A variety of performance improvements have been made for sharded
|
|
container databases.
|
|
|
|
- |
|
|
Various logging and metrics improvements when talking to memcache.
|
|
|
|
- |
|
|
Improved formatting of meta and sysmeta for ``swift-account-info`` and
|
|
``swift-container-info``.
|
|
|
|
upgrade:
|
|
- |
|
|
Previously, under some circumstances, a non-standard config option such
|
|
as ``RECLAIM_AGE`` might get parsed as ``reclaim_age`` for some processes
|
|
but ignored by others. Now, all config parsing is case-sensitive;
|
|
non-standard names will always be ignored.
|
|
|
|
- |
|
|
The structure of cached shard ranges has changed, improving performance
|
|
when listing or writing to sharded containers. Note that immediately
|
|
after upgrade, the new structures will all be cache misses, which may
|
|
lead to a thundering herd problem. To avoid this, upgrade just a few
|
|
nodes first, let them service some fraction of traffic to populate the
|
|
cache, then upgrade the rest of the cluster.
|
|
|
|
deprecations:
|
|
- |
|
|
Removed the hard dependency on netifaces; it may still be used if the
|
|
``getifaddrs`` C function is not available. This fallback support may be
|
|
removed in a future release.
|
|
|
|
fixes:
|
|
- |
|
|
Python 3 fixes:
|
|
|
|
* Python 3 object servers can now read unencrypted non-ASCII metadata
|
|
that was written under Python 2.
|
|
|
|
* Ssync no longer corrupts unencrypted non-ASCII metadata during
|
|
transfers.
|
|
|
|
* Fixed an encoding issue when writing non-ASCII object names to sharded
|
|
containers and shard range caching is not enabled.
|
|
|
|
* Fixed an encoding issue when handling non-ASCII account names.
|
|
|
|
* Fixed a ``generator already executing`` error on client disconnect.
|
|
|
|
* Suppressed ``RemoteDisconnected`` tracebacks.
|
|
|
|
- |
|
|
Fixed an issue that prevented proxy servers from emitting metrics and
|
|
logs for backend requests made when getting account or container info.
|
|
|
|
- |
|
|
Fixed ssync's handling of timestamp offsets. Previously, this could cause
|
|
ssync to fail with a 409 Conflict, causing the transfer to fail and
|
|
preventing handoffs from clearing.
|
|
|
|
- |
|
|
Fixed an issue where an erasure-coded PUT could prevent other requests
|
|
from being processed when network calls rarely or never blocked.
|
|
|
|
- |
|
|
Fixed an issue when downloading an SLO manifest would hit a recoverable
|
|
error and attempt to resume from another node. This would manifest as
|
|
either a pyeclib decode error or an unexpected empty response.
|
|
|
|
- |
|
|
The proxy server now applies error-limiting to the correct node when
|
|
handling a recoverable node error.
|
|
|
|
- |
|
|
Account, container, and object log fields are now correctly identified
|
|
when returning ``BadDigest`` responses to S3 requests.
|
|
|
|
- |
|
|
Reduced the backend load of making ``?versions`` requests to a container
|
|
that has never had object versioning enabled.
|
|
|
|
- |
|
|
The standard-library ``logging`` module is no longer monkey-patched when
|
|
importing ``swift.common.utils``, making it easier to re-use swift code
|
|
in other contexts.
|
|
|
|
- |
|
|
Various other minor bug fixes and improvements.
