swift (1.11.0)
* Added discoverable capabilities
A Swift proxy server now by default (although it can be turned off)
will respond to requests to /info. The response to these requests
include information about the cluster and can be used by clients to
determine which features are supported in the cluster.
* Object replication ssync (an rsync alternative)
A Swift storage node can now be configured to use Swift primitives
for replication transport instead of rsync. This is an experimental
feature that is not yet considered production ready.
* If a source times out on an object server read, try another one
of them with a modified range.
* The proxy now responds to many types of requests as soon as it
has a quorum. This can help speed up responses (without
changing the results), especially when one node is acting up.
There is a post_quorum_timeout config value that can tune how
long to wait for requests to finish after a quorum has been
established.
* Add accurate timestamps in proxy log lines for the start and
end of a request. These are added as new fields on the end of
the existing log lines, and therefore should not break
existing, well-behaved log processors.
* Add an "inline" query parameter to tempurl
By default, temporary URLs add a "Content-Disposition" header
that forces many clients to download the object. Now, temporary
URLs support an optional "inline" query parameter that will
force a "Content-Disposition: inline" header to be added to the
response, overriding the default.
* Use TCP_NODELAY for created sockets. This can dramatically
lower latency for small object workloads.
* DiskFile API, with reference implementation
The DiskFile abstraction for talking to data on disk has been
refactored to allow alternate implementations to be developed.
Included in the codebase is an in-memory reference
implementation. For full documentation, please see
http://docs.openstack.org/developer/swift/development_ondisk_backends.html
* Removal of swift-bench
The included benchmarking tool swift-bench has been extracted
from the codebase and is now in its own repository at
https://github.com/openstack/swift-bench. New swift-bench
binaries and packages may be found on PyPI at
https://pypi.python.org/pypi/swift-bench
* Bulk delete now also supports the POST verb, in addition to DELETE
* Added functionality to the swift-ring-builder to support
limited recreation of ring builder files from the ring file itself.
* HEAD on account now returns 410 if account was deleted and
not yet reaped. The old behavior was to return a 404.
* Fixed a bug introduced since the 1.10.0 release that
prevented expired objects from being removed from the system.
This resulted in orphaned expired objects taking up space on
the system but inaccessible to the API. This regression and
fix are only important if you have deployed code since the
1.10.0 release. For a full discussion, including a script that
can be used to clean up orphaned objects, see
https://bugs.launchpad.net/swift/+bug/1257330
* Tie socket write buffer size to server chunk size parameter. This
pairs the underlying network buffer size with the size of data
that Swift attempts to read from the connection, thereby
improving efficiency and throughput on connections.
* Fix 500 from account-quota middleware. If a user had set
X-Account-Meta-Quota-Bytes to something non-integer prior to
the installation of the account-quota middleware, then the
quota check would choke on it. Now a non-integer value is
treated as "no quota".
* Quarantine objects with busted metadata. Before, if you
encountered an object with corrupt or missing xattrs, the
object server would return a 500 on GET, and wouldn't quarantine
anything. Now the object server returns a 404 for that GET and
the corrupted file is quarantined, thus giving replication a
chance to fix it.
* Fix quarantine and error counts in audit logs
* Report transaction ID in failure exception logs
* Make pbr a build-time only dependency
* Worked around a bug in eventlet 0.9.16 where the size of the
memcache connection pools would grow unbounded.
* Tempurl keys are now properly stored as utf8
* Fixed an issue where concurrent PUT requests to accounts or
containers may result in errors due to locked databases.
* Handle copy requests in account and container quota middleware
* Now ensure that a WWW-Authenticate header is on all 401 responses
* Various other bug fixes and improvements
swift (1.10.0)
* Added support for pooling memcache connections
