Raw Blame History

swift (1.6.0)
* Removed bin/swift and swift/common/client.py from the swift repo. These
tools are now managed in the python-swiftclient project. The
python-swiftclient project is a second deliverable of the openstack
swift project.
* Moved swift_auth (openstack keystone) middleware from keystone project
into swift project
* Made dispersion report work with any replica count other than 3. This
substantially affects the JSON output of the dispersion report, and any
tools written to consume this output will need to be updated.
* Added Solaris (Illumos) compability
* Added -a option to swift-get-nodes to show all handoffs
* Add UDP protocol support for logger
* Added config options for rate limiting of large object downloads.
* Added config option `log_handoffs` (defaults to True) to proxy server
to log and update statsd with information about when a handoff node is
used. This is helpful to track the health of the cluster.
* swift-bench can now use auth 2.0
* Support forbidding substrings based on a regexp in name_filter
middleware
* Hardened internal server processes so only authorized methods can be
called.
* Made ranged requests on large objects work correctly when size of
manifest file is not 0 byte
* Added option to dispersion report to print 404s to stdout
* Fix object replication on older rsync versions when using ipv4
* Fixed bug with container reclaim/report race
* Make object server's caching more configurable.
* Check disk failure before syncing for each partition
* Allow special characters to be referenced by manifest objects
* Validate devices and partitions to avoid directory traversals
* Support WebOb 1.2
* Ensure that accessing the ring devs reloads the ring if necessary.
Specifically, this allows replication to work when it has been started
with an empty ring.
* Various other minor bug fixes and improvements
swift (1.5.0)
* New option to toggle SQLite database preallocation with account
and container servers.
IMPORTANT:
The default for database preallocation is now off when before
it was always on. This will affect performance on clusters that
use standard drives with shared account, container, object
servers. Such deployments will need to update their
configurations to turn database preallocation back on (see
account-server.conf-sample and container-server.conf.sample
files).
If you are using dedicated account and container servers with
SSDs, you should defragment your file systems after upgrade and
should notice dramatically less disk usage.
* swift3 middleware removed and moved to http://github.com/fujita/swift3.
This will require a config change in the proxy server and adds a new
dependency for deployers using this middleware.
* Moved proxy server logging to middleware. This requires a config change
in the proxy server.
* Added object versioning feature. (See docs for full description)
* Add statsd logging throughout the system (beta, some event names may
change)
* Expanded swift-recon middleware support
* The ring builder now supports as-unique-as-possible partition
placement, unified balancing methods, and can work on more than one
device at a time.
* Numerous bug fixes to StaticWeb (previously unusable at scale).
* Bug fixes to all middleware to allow passthrough requests under various
conditions and to share pre-authed request code (which previously had
differing behaviors and interaction bugs).
* Bug fix to object expirer that could cause infinite looping.
* Added optional delay to account reaping.
* Async-pending write optimization.
* Dispersion tools now support multiple auth versions
* Updated man pages
* Proxy server can now deny requests to particular hostnames
* Updated docs for domain remap middleware
* Updated docs for cname lookup middleware
* Made swift CLI binary easier to wrap
* Proxy will now also return X-Timestamp header
* Added associated projects doc as a place to track ecosystem projects
* end_marker made consistent across both object and container listings
* Various other minor bug fixes and improvements
swift (1.4.8)
* Added optional max_containers_per_account restriction
* Added alternate metadata header removal method
* Added optional name_check middleware filter

non-StaticWeb-enabled containers (immediately 404s instead of passing
the request on down the WSGI pipeline).

* Swift-Recon-related fix to create temporary files on the same disk as
their final destinations.

* Fixed swift3 middleware to allow Content-Range header in response
