Raw Blame History

swift (2.1.0)
* swift-ring-builder placement was improved to allow gradual addition
of new regions without causing a massive migration of data to the new
region. The change was to prefer device weight first, then look at
failure domains.
* Logging updates
- Eliminated "Handoff requested (N)" log spam.
- Added process pid to the end of storage node log lines.
- Container auditor now logs a warning if the devices path contains a
non-directory.
- Object daemons now send a user-agent string with their full name.
* 412 and 416 responses are no longer tracked as errors in the StatsD
messages from the backend servers.
* Parallel object auditor
The object auditor can now be controlled with a "concurrency" config
value that allows multiple auditor processes to run at once. Using
multiple parallel auditor processes can speed up the overall auditor
cycle time.
* The object updater will now concurrently update each necessary node
in a new greenthread.
* TempURL updates
- The default allowed methods have changed to also allow POST and
DELETE. The new default list is "GET HEAD PUT POST DELETE".
- TempURLs for POST now also allow HEAD, matching existing GET and PUT
functionality.
- Added filename*= support to TempURL Content-Disposition response
header.
* X-Delete-At/After can now be used with the FormPost middleware.
* Make swift-form-signature output a sample form.
* Add v2 API to list endpoints middleware
The new API adds better support for storage policies and changes the
response from a list of backend urls to a dictionary with the keys
"endpoints" and "headers". The endpoints key contains a list of the
backend urls, and the headers key is a dictionary of headers to send
along with the backend request.
* Added allow_account_management and account_autocreate values to /info
responses.
* Enable object system metadata on PUTs (Note: POST support is ongoing).
* Various other minor bug fixes and improvements.
swift (2.0.0)
* Storage policies
Storage policies allow deployers to configure multiple object rings
and expose them to end users on a per-container basis. Deployers
can create policies based on hardware performance, regions, or other
criteria and independently choose different replication factors on
them. A policy is set on a Swift container at container creation
time and cannot be changed.
Full docs are at http://swift.openstack.org/overview_policies.html
* Add profiling middleware in Swift
The profile middleware provides a tool to profile Swift
code on the fly and collects statistical data for performance
analysis. A native simple Web UI is also provided to help
query and visualize the data.
* Add --quoted option to swift-temp-url
* swift-recon now supports checking the md5sum of swift.conf, which
helps deployers verify configurations are consistent across a cluster.
* Users can now set the transaction id suffix by passing in
a value in the X-Trans-Id-Extra header.
* New log_max_line_length option caps the maximum length of a log line.
* Support If-[Un]Modified-Since for object HEAD
* Added missing constraints and ratelimit parameters to /info
* Add ability to remove subsections from /info
* Unify logging for account, container, and object server processes
to provide a consistent message format. This change reorders the
fields logged for the account server.
* Add targeted config loading to swift-init. This allows an easier
and more explicit way to tell swift-init to run specific server
process configurations.
* Properly quote www-authenticate (CVE-2014-3497)
* Fix logging issue when services stop on py26.
* Change the default logged length of the auth token to 16.
* Explicitly set permissions on generated ring files to 0644
* Fix file uploads larger than 2GiB in the formpost feature
* Fixed issue where large objects would fail to download if the
auth token expired partway through the download
* Various other minor bug fixes and improvements
swift (1.13.1)
* Change the behavior of CORS responses to better match the spec
A new proxy config variable (strict_cors_mode, default to True)
has been added. Setting it to False keeps the old behavior. For
an overview of old versus new behavior, please see
https://review.openstack.org/#/c/69419/
* Invert the responsibility of the two instances of proxy-logging in
the proxy pipeline
The first proxy_logging middleware instance to receive a request
in the pipeline marks that request as handling it. So now, the
left most proxy_logging middleware handles logging for all
client requests, and the right most proxy_logging middleware
handles all other requests initiated from within the pipeline to
its left. This fixes logging related to large object
requests not properly recording bandwidth.
* Added swift-container-info and swift-account-info tools
* Allow specification of object devices for audit
* Dynamic large object COPY requests with ?multipart-manifest=get
now work as expected
* When a client is downloading a large object and one of the segment
reads gets bad data, Swift will now immediately abort the request.
* Fix ring-builder crash when a ring partition was assigned to a
deleted device, zero-weighted device, and normal device
* Make probetests work with conf.d configs
* Various other minor bug fixes and improvements.
swift (1.13.0)
* Account-level ACLs and ACL format v2
Accounts now have a new privileged header to represent ACLs or
any other form of account-level access control. The value of
the header is a JSON dictionary string to be interpreted by the
auth system. A reference implementation is given in TempAuth.
Please see the full docs at
http://swift.openstack.org/overview_auth.html
* Added a WSGI environment flag to stop swob from always using
absolute location. This is useful if middleware needs to use
out-of-spec Location headers in a response.
* Container sync proxies now support simple load balancing
* Config option to lower the timeout for recoverable object GETs
* Add a way to ratelimit all writes to an account
* Allow multiple storage_domain values in cname_lookup middleware
* Moved all DLO functionality into middleware
The proxy will automatically insert the dlo middleware at an
appropriate place in the pipeline the same way it does with the
gatekeeper middleware. Clusters will still support DLOs after upgrade
even with an old config file that doesn't mention dlo at all.
* Remove python-swiftclient dependency
* Add secondary groups to process user during privilege escalation
* When logging request headers, it is now possible to specify
specifically which headers should be logged
* Added log_requests config parameter to account and container servers
to match the parameter in the object server. This allows a deployer
to turn off log messages for these processes.
* Ensure swift.source is set for DLO/SLO requests
* Fixed an issue where overwriting segments in a dynamic manifest
could cause issues on pipelined requests.
* Properly handle COPY verb in container quota middleware
* Improved StaticWeb 404 error message on web-listings and index
* Various other minor bug fixes and improvements.
swift (1.12.0)
* Several important pieces of information have been added to /info:
- Configured constraints are included and allow a client to discover
the limits on names and object sizes that the cluster supports.
- The supported tempurl methods are now included.
- Static large object constraints are now included.
* The Last-Modified header value returned will now be the object's
timestamp rounded up to the next second. This allows subsequent
requests with If-[un]modified-Since to use the Last-Modified
value as expected.
* Non-integer values for if-delete-at headers will now properly
report a 400 error instead of a 503.
* Fix object versioning with non-ASCII container names.
* Bulk delete with POST now works properly.
* Generic means for persisting system metadata
Swift now supports system-level metadata on accounts and
containers. System metadata provides a means to store internal
custom metadata with associated Swift resources in a safe and
secure fashion without actually having to plumb custom metadata
through the core swift servers. The new gatekeeper middleware
prevents this system metadata from leaking into the request or
being set by a client.
* catch_errors and gatekeeper middleware are now forced into the proxy
pipeline if not explicitly referenced.
* New container sync configuration option, separating the end user
from knowing the required end point and adding more secure
signed requests. See
http://swift.openstack.org/overview_container_sync.html for full
information.
* bulk middleware now can be configured to retry deleting containers.
* The default yield_frequency used to keep client connections alive
during slow bulk requests was reduced from 60 seconds to 10 seconds.
While this is a change to a default, it should not affect deployments
and there is no migration process needed.
* Swift processes will attempt to set RLIMIT_NPROC to 8192.
* Server processes will now exit with a non-zero error code on config
errors.
* Warn if read_affinity is configured but not enabled.
* Fix checkmount error parsing in swift-recon.
* Log at warn level when an object is quarantined.
* Fixed CVE-2014-0006 to avoid a potential timing attack with tempurl.
* Various other minor bug fixes and improvements.
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 the developer
documentation. The DiskFile API is still a work in progress and
is not yet finalized.
* 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
* Added support to replicating handoff partitions first in object
replication. Can also configure how many remote nodes a storage node
must talk to before removing a local handoff partition.
* Fixed bug where memcache entries would not expire
* Much faster calculation for choosing handoff nodes
* Added container listing ratelimiting
* Fixed issue where the proxy would continue to read from a storage
server even after a client had disconnected
* Added support for headers that are only visible to the owner of a Swift
account
* Fixed ranged GET with If-None-Match
* Fixed an issue where rings may not be balanced after initial creation
* Fixed internationalization support
* Return the correct etag for a static large object on the PUT response
* Allow users to extract archives to containers with ACLs set
* Fix support for range requests against static large objects
* Now logs x-copy-from header in a useful place
* Reverted back to old XML output of account and container listings to
ensure older clients do not break
* Account quotas now appropriately handle copy requests
* Fix issue with UTF-8 handling in versioned writes
* Various other bug fixes and improvements, including support for running
Swift under Pypy and continuing work to support storage policies
swift (1.9.1)
* Disallow PUT, POST, and DELETE requests from creating older tombstone
files, preventing the possibility of filling up the disk and removing
unnecessary container updates.
* Set default wsgi workers to cpu_count
Change the default value of wsgi workers from 1 to auto. The new
default value for workers in the proxy, container, account & object
wsgi servers will spawn as many workers per process as you have cpu
cores. This will not be ideal for some configurations, but it's much
more likely to produce a successful out of the box deployment.
* Added reveal_sensitive_prefix config setting to filter the auth token
logged by the proxy server.
* Ensure Keystone's reseller prefix ends with an underscore. Previously
this was a recommendation--now it is enforced.
* Added log_file_pattern config to swift-drive-audit for drive errors
* Add support for telling Swift to detect a content type on a request.
* Additional object stats are now logged in the object auditor
* Moved the DiskFile interface into its own module
* Ensure the SQLite cursors are closed when creating functions
* Better support for valid Accept headers
* In Keystone, don't allow users to delete their own account
* Return a UTC timezone designator in container listings
* Ensure that users can't remove their account quotas
* Allow floating point value for dispersion coverage
* Fix incorrect error page handling in staticweb
* Add utf-8 charset to multipart-manifest=get response.
* Allow dispersion tools to use keystone server with insecure certificate
* Ensure that files are always closed in tests
* Use OpenStack's "Hacking" guidelines for code formatting
* Various other minor bug fixes and improvements
swift (1.9.0)
* Global clusters support
The "region" concept introduced in Swift 1.8.0 has been augmented with
support for using a separate replication network and configuring read
and write affinity. These features combine to offer support for a single
Swift cluster spanning wide geographic area.
* Disk performance
The object server now can be configured to use threadpools to increase
performance and smooth out latency throughout the system. Also, many
disk operations were reordered to increase reliability and improve
performance.
* Added config file conf.d support
Allow Swift daemons and servers to optionally accept a directory as the
configuration parameter. This allows different parts of the config file
to be managed separately, eg each middleware could use a separate file
for its particular config settings.
* Allow two TempURL keys per account
By adding a second key, a user can safely rotate keys and prevent URLs
already in use from becoming invalid. TempURL middlware has also been
updated to allow a configuable set of allowed methods and to prevent a
bugrelated to content-disposition names.
* Added crossdomain.xml middleware. See
http://docs.openstack.org/developer/swift/crossdomain.html for details
* Added rsync bandwidth limit setting for object replicator
* Transaction ID updated to include the time and an optional suffix
* Added x-remove-versions-location header to disable versioned writes
* Improvements to support for Keystone ACLs
* Added parallelism to object expirer daemon
* Added support for ring hash prefix in addition to the existing suffix
* Allow all headers requested for CORS
* Stop getting useless bytes on manifest Range requests
* Improved container-sync resiliency
* Added example Apache config files. See
http://docs.openstack.org/developer/swift/apache_deployment_guide.html
for more info
* If an account is marked as deleted but hasn't been reaped and is still
on disk, responses will include an "X-Account-Status" header
* Fix 503 on account/container HEAD with invalid format
* Added extra safety on account-level DELETE when using bulk deletes
* Made colons quote-safe in logs (mainly for IPv6)
* Fixed bug with bulk delete max items
* Fixed static large object manifest range requests
* Prevent static large objects from containing other static large objects
* Fixed issue with use of delimiter in container queries where some
objects would not be listed
* Various other minor bug fixes and improvements
swift (1.8.0)
* Make rings' replica count adjustable
* Added a region tier to the ring above zones
* Added timing-based sorting of object servers on read requests
* Added support for auto-extract archive uploads
* Added support for bulk delete requests
* Added support for large objects with static manifests
* Added list_endpoints middleware to provide an API for determining where
the ring places data
* proxy-logging middleware can now handle logging for other middleware
proxy-logging should be used twice in the proxy pipeline. The first
handles middleware logs for requests that never made it all the way
to the server. The last handles requests that do make it to the server.
This is a change that may require an update to your proxy server
config file or custom middleware that you may be using. See the full
docs at http://docs.openstack.org/developer/swift/misc.html#module-swift.common.middleware.proxy_logging.
* Changed the default sample rate for a few high-traffic requests.
Added log_statsd_sample_rate_factor to globally tune the StatsD
sample rate. This tunable can be used to reduce StatsD traffic
proportionally for all metrics and is intended to replace
log_statsd_default_sample_rate, which is left alone for
backward-compatibility, should anyone be using it.
* Added swift_hash_path_prefix option to swift.conf
New deployments are advised to set this value to a random secret
to protect against hash collisions
* Added user-managed container quotas
* Added support for account-level quotas managed by an auth reseller
* Added --run-dir option to swift-init
* Added more options to swift-bench
* Added support for CORS "actual requests"
* Added fallocate_reserve option to protect against full drives
* Allow ring rebalance to take a seed
* Ring serialization will now produce the same gzip file (Py2.7)
* Added support to swift-drive-audit for handling rotated logs
* Added first-byte latency timings for GET requests
* Added per disk PUT timing monitoring support
* Added speed limit options for DB auditor
* Force log entries to be one line
* Ensure that fsync is used and not just fdatasync
* Improved handoff node selection
* Deprecated keystone is_admin feature
* Fix large objects with unicode in the segment names
* Update Swift's MemcacheRing to provide API compatibility with
standard Python memcache libraries

swift (1.7.6)
* Better tempauth storage URL guessing
* Added --top option to swift-recon -d
* Allow optional, temporary healthcheck failure
* keystoneauth middleware now supports cross-tenant ACLs
* Add dispersion report flags to limit reports
* Add config option to turn eventlet debug on/off
* Added override option for swift-init's KILL_WAIT

* Fixed bug in deleting memcached account info data
* Fixed lazy-listing of object manifest segments
* Fixed bug where a ? in the object name caused an error
* Swift now returns 406 if it can't satisfy Accept
* Fix infinite recursion bug in object replicator
* Swift will now reject names with NULL characters
* Fixed object-auditor logging to use a minimum of unix sockets
* Various other minor bug fixes and improvements
swift (1.7.5)
* Support OPTIONS verb, including CORS preflight requests
* Added support for custom log handlers
* Range support is extended to support GET requests with multiple ranges.
Multi-range GETs are not yet supported against large-object manifests.
* Cluster constraints are now settable by config
* Replicators can now run against specific devices or partitions
* swift-bench now supports running on multiple cores and multiple servers
* Added partition option to swift-get-nodes
* Allow underscores in account and user in tempauth via base64 encodings
* New option to the dispersion report to output the missing partitions
* Changed storage server StatsD metrics to report timings instead of
counts for errors. See the admin guide for the updated metric names.
* Removed a dependency on WebOb and replaced it with an internal module
* Fixed config parsing in swift-bench -x
* Fixed sample_rate in StatsD logging
* Track unlinks of async_pendings with StatsD
* Remove double GET on range requests
* Allow unsetting of X-Container-Sync-To and ACL headers
* DB reclamation now removes empty suffix directories
* Fix non-standard 100-continue behavior
* Allow object-expirer to delete the last copy of a versioned object
* Only set TCP_KEEPIDLE on systems where it is supported
* Fix stdin flush and fdatasync issues on BSD platforms
* Allow object-expirer to delete the last version of an object
* Various other minor bug fixes and improvements
swift (1.7.4)
* Fix issue where early client disconnects may have caused a memory leak
swift (1.7.2)
* Fix issue where memcache serialization was not properly loading
the config value
swift (1.7.0)
* Use custom encoding for ring data instead of pickle
Serialize RingData in a versioned, custom format which is a combination
of a JSON-encoded header and .tostring() dumps of the
replica2part2dev_id arrays. This format deserializes hundreds of times
faster than rings serialized with Python 2.7's pickle (a significant
performance regression for ring loading between Python 2.6 and Python
2.7). Fixes bug 1031954.
The new implementation is backward-compatible; if a ring
does not begin with a new-style magic string, it is assumed to be an
old-style pickle-dumped ring and is handled as before. So new Swift
code can read old rings, but old Swift code will not be able to read
newly-serialized rings.
* Do not use pickle for serialization in memcache, but JSON
To avoid issues on upgrades (unability to read pickled values, and cache
poisoning for old servers not understanding JSON), we add a
memcache_serialization_support configuration option, with the following
values:
0 = older, insecure pickle serialization
1 = json serialization but pickles can still be read (still insecure)
2 = json serialization only (secure and the default)
To avoid an instant full cache flush, existing installations should
upgrade with 0, then set to 1 and reload, then after some time (24
hours) set to 2 and reload. Support for 0 and 1 will be removed in
future versions.
* Update proxy-server StatsD logging. This is a significant change to the
existing StatsD intigration. Docs for this feature can be found in
doc/source/admin_guide.rst.
* Improved swift-bench to allow random object sizes and better usability
* Updated probe tests
* Replicator removal metrics are now generated on a per-device basis
* Made object replicator locking more optimistic
* Split proxy-server code into separate modules
* Fixed bug where swift-recon would not report all unmounted drives
* Fixed issue where a LockTimeout may have caused a file descriptor to
not be closed properly
* Fixed a bug where an error may have caused the proxy to stop returning
data to a client
* Fixed bug where expirer would get confused by odd deletion times
* Fixed a bug where auto-creating accounts would return an error if they
were recreated after being deleted
* Fix when rate_limit_after_segment kicks in
* fallocate() failures properly return HTTPInsufficientStorage from
object-server before reading from wsgi.input, allowing the proxy
server to quickly error_limit that node
* Fixed error with large object manifests and x-newest headers on GET
* Various other minor bug fixes and improvements
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) compatibility
* 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

* 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
* Added support for venv-based test runs with tox
* StaticWeb behavior change with X-Web-Mode: true and
non-StaticWeb-enabled containers (immediately 404s instead of passing
the request on down the WSGI pipeline).
* Fixed typo in swift-dispersion-report JSON output.
* Swift-Recon-related fix to create temporary files on the same disk as
their final destinations.
* Updated return codes in swift3 middleware
* Fixed swift3 middleware to allow Content-Range header in response
* Updated swift.common.client and swift CLI tool with auth 2.0 changes
* Swift CLI tool now supports common openstack auth args
* Body of HTTP responses now included in error messages of swift CLI tool
* Refactored some ring building functions for clarity and simplicity
swift (1.4.7)
* Improvements to account and container replication.
* Fix for account servers allowing .pending to exist before .db.
* Fixed possible key-guessing exploit in formpost.
* Fixed bug in ring builder when removing a large percentage of devices.
* Swift CLI tool now supports openstack-standard CLI flags.
* New JSON output option for swift-dispersion-report.
* Removed old stats tools.
* Other bug fixes and documentation updates.
swift (1.4.6)

* Consistent formatting on Last-Modified response header
* Added timeout option to swift-recon
* Allow arguments to be passed to nosetest
* Removed tools/rfc.sh
