Thu Mar 28 10:52:33 UTC 2019 - Johannes Grassler <johannes.grassler@suse.com>
- Update to version 2.19.2.dev1
* Imported Translations from Zanata
* Fixing target for cross-ref 'get_data_dir'
-------------------------------------------------------------------
Sun Feb 17 02:58:00 UTC 2019 - cloud-devel@suse.de
- Update to version swift-2.19.1.dev13:
2.19.1 (rocky stable backports)
* Prevent PyKMIP's kmip_protocol logger from logging at DEBUG.
Previously, some versions of PyKMIP would include all wire
data when the root logger was configured to log at DEBUG; this
could expose key material in logs. Only the kmip_keymaster was
affected.
* Fixed an issue where a failed drive could prevent the container sharder
from making progress.
* Fixed a bug in how Swift uses eventlet that was exposed under high
concurrency.

swift (2.19.0, OpenStack Rocky)
-------------------------------------------------------------------
Wed Aug 22 04:51:30 UTC 2018 - cloud-devel@suse.de
- Update to version swift-2.18.1.dev229:
swift (2.19.0)
* 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]
-------------------------------------------------------------------
Mon Aug 20 13:52:40 UTC 2018 - comurphy@suse.com
- Update to version swift-2.18.1.dev224:
swift (2.18.0)
* Added container sharding, an operator controlled feature that
may be used to shard very large container databases into a
number of smaller shard containers. This mitigates the issues
with one large DB by distributing the data across multiple
smaller databases throughout the cluster. Please read the full
overview at
https://docs.openstack.org/swift/latest/overview_container_sharding.html
* Provide an S3 API compatibility layer. The external "swift3"
project has been imported into Swift's codebase as the "s3api"
middleware.
* Added "emergency mode" hooks in the account and container replicators.
These options may be used to prioritize moving handoff
partitions to primary locations more quickly. This helps when
adding capacity to a ring.
- Added `-d <devs>` and `-p <partitions>` command line options.
- Added a handoffs-only mode.
* Add a multiprocess mode to the object replicator. Setting the
"replicator_workers" setting to a positive value N will result
in the replicator using up to N worker processes to perform
replication tasks. At most one worker per disk will be spawned.
Worker process logs will have a bit of information prepended so
operators can tell which messages came from which worker. The

Sat Feb 3 04:23:09 UTC 2018 - cloud-devel@suse.de
- Update to version swift-2.16.1.dev191:
swift (2.17.0)
* Added symlink objects support.
Symlink objects reference one other object. They are created by
creating an empty object with an X-Symlink-Target header. The value of
the header is of the format <container>/<object>, and the target does
not need to exist at the time of symlink creation. Cross-account
symlinks can be created by including the
X-Symlink-Target-Account header.
GET and HEAD requests to a symlink will operate on the
referenced object and require appropriate permission in the
target container. DELETE and PUT requests will operate on the
symlink object itself. POST requests are not forwarded to the
referenced object. POST requests sent to a symlink will result
in a 307 Temporary Redirect response.
* Added support for inline data segments in SLO manifests.
Upgrade impact: during a rolling upgrade, an updated proxy server
may write a manifest that an out-of-date proxy server will not be
able to read. This will resolve itself once the upgrade completes
on all nodes.
* The tempurl digest algorithm is now configurable, and Swift added
support for both SHA-256 and SHA-512. Supported tempurl digests
are exposed to clients in `/info`. Additionally, tempurl signatures
can now be base64 encoded.
-------------------------------------------------------------------
Tue Dec 12 09:10:52 UTC 2017 - gosipyan@suse.com
- Update to version swift-2.16.1.dev21:
swift (2.16.0)
* Add checksum to object extended attributes.
* Let clients request heartbeats during SLO PUTs by including
the query parameter `heartbeat=on`.
With heartbeating turned on, the proxy will start its response
immediately with 202 Accepted then send a single whitespace
character periodically until the request completes. At that
point, a final summary chunk will be sent which includes a
"Response Status" key indicating success or failure and (if
successful) an "Etag" key indicating the Etag of the resulting
SLO.
* Added support for retrieving the encryption root secret from an
external key management system. In practice, this is currently limited
to Barbican.
* Move listing formatting out to a new proxy middleware named
`listing_formats`. `listing_formats` should be just right of the
first proxy-logging middleware, and left of most other
middlewares. If it is not already present, it will be
automatically inserted for you.
Note: if you have a custom middleware that makes account or
container listings, it will only receive listings in JSON format.
* Log deprecation warning for `allow_versions` in the container
server config. Configure the `versioned_writes` middleware in

- Fix doc build
-------------------------------------------------------------------
Sat Aug 19 04:01:25 UTC 2017 - cloud-devel@suse.de
- Update to version swift-2.15.1.dev43:
swift (2.15.1)
* Fixed a bug introduced in 2.15.0 where the object reconstructor
would exit with a traceback if no EC policy was configured.
* Fixed deadlock when logging from a tpool thread.
The object server runs certain IO-intensive methods outside the
main pthread for performance. Previously, if one of those methods
tried to log, this can cause a crash that eventually leads to an
object server with hundreds or thousands of greenthreads, all
deadlocked. The fix is to use a mutex that works across different
greenlets and different pthreads.
* The object reconstructor can now rebuild an EC fragment for an
expired object.
* Various other minor bug fixes and improvements.
-------------------------------------------------------------------
Fri Jul 28 05:11:37 UTC 2017 - cloud-devel@suse.de
- Update to version swift-2.14.1.dev183:
swift (2.15.0)
* Add Composite Ring Functionality
A composite ring comprises two or more component rings that are
combined to form a single ring with a replica count equal to the
sum of the component rings. The component rings are built
independently, using distinct devices in distinct regions, which
means that the dispersion of replicas between the components can
be guaranteed.
Composite rings can be used for explicit replica placement and
"replicated EC" for global erasure codes policies.
Composite rings support 'cooperative' rebalance which means that
during rebalance all component rings will be consulted before a
partition is moved in any component ring. This avoids the same
partition being simultaneously moved in multiple components.
We do not yet have CLI tools for creating composite rings, but
the functionality has been enabled in the ring modules to
support this advanced functionality. CLI tools will be delivered
in a subsequent release.
For further information see the docs at
<https://docs.openstack.org/swift/latest/overview_ring.html#module-swift.common.ring.composite_builder>
* The EC reconstructor process has been dramatically improved by
adding support for multiple concurrent workers. Multiple
processes are required to get high concurrency, and this change

Thu Apr 27 03:29:10 UTC 2017 - cloud-devel@suse.de
- Update to version swift-2.13.1.dev153:
swift (2.14.0)
* Fixed error where a container drive error resulted in double space
usage on rest drives. When drive with container or account database
is unmounted, the bug would create handoff replicas on all remaining
drives, increasing the drive space used and filling the cluster.
* Fixed UnicodeDecodeError in the object reconstructor that would
prevent objects with non-ascii names from being reconstructed and
caused the reconstructor process to hang.
* EC Fragment Duplication - Foundational Global EC Cluster Support.
* Fixed encoding issue in ssync where a mix of ascii and non-ascii
metadata values would cause an error.
* `name_check` and `cname_lookup` keys have been added to `/info`.
* Add Vary: headers for CORS responses.
* Always set Swift processes to use UTC.
* Prevent logged traceback in object-server on client disconnect for
chunked transfers to replicated policies.
* Removed per-device reconstruction stats. Now that the reconstructor
is shuffling parts before going through them, those stats no longer
make sense.
* Log correct status code for conditional requests.

Fri Feb 17 04:11:14 UTC 2017 - cloud-devel@suse.de
- Update to version swift-2.12.1.dev107:
swift (2.13.0, OpenStack Ocata)
* Improvements in key parts of the consistency engine
- Improved performance by eliminating an unneeded directory
structure hash.
- Optimized the common case for hashing filesystem trees, thus
eliminating a lot of extraneous disk I/O.
- Updated the `hashes.pkl` file format to include timestamp information
for race detection. Also simplified hashing logic to prevent race
conditions and optimize for the common case.
- The erasure code reconstructor will now shuffle work jobs across all
disks instead of going disk-by-disk. This eliminates single-disk I/O
contention and allows continued scaling as concurrency is increased.
- Erasure code reconstruction handles moving data from handoff nodes
better. Instead of moving the data to another handoff, it waits
until it can be moved to a primary node.
Upgrade Impact: If you upgrade and roll back, you must delete all
`hashes.pkl` files.
* If using erasure coding with ISA-L in rs_vand mode and 5 or more parity
fragments, Swift will emit a warning. This is a configuration that is
known to harm data durability. In a future release, this warning will be
upgraded to an error unless the policy is marked as deprecated. All data
in an erasure code storage policy using isa_l_rs_vand with 5 or more
-------------------------------------------------------------------
Thu Dec 15 04:11:05 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.11.1.dev70:
swift (2.12.0)
* Ring files now include byteorder information about the endian of
the machine used to generate the file, and the values are
appropriately byteswapped if deserialized on a machine with a
different endianness.
Newly created ring files will be byteorder agnostic, but
previously generated ring files will still fail on different
endian architectures. Regenerating older ring files will cause
them to become byteorder agnostic. The regeneration of the ring
files will not cause any new data movement. Newer ring files
will still be usable by older versions of Swift (on machines
with the same endianness--this maintains existing behavior).
* All 416 responses will now include a Content-Range header with
an unsatisfied-range value. This allows the caller to know the
valid range request value for an object.
* TempURLs now support a validation against a common prefix. A
prefix-based signature grants access to all objects which share the
same prefix. This avoids the creation of a large amount of signatures,
when a whole container or pseudofolder is shared.
* Correctly handle deleted files with if-none-match requests.
* Correctly send 412 Precondition Failed if a user sends an
invalid copy destination. Previously Swift would send a 500
Internal Server Error.
-------------------------------------------------------------------
Sat Nov 19 05:56:11 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.11.1.dev5:
swift (2.11.0)
* We have made significant improvements and changes to the erasure
code implementation.
- Instead of using a separate .durable file to indicate the
durable status of an EC fragment archive, we rename the .data
to include a durable marker in the filename. This saves one
inode for every EC .data file. Existing .durable files will not
be removed, and they will continue to work just fine.
Note that after writing EC data with Swift 2.11.0 or later, that
data will not be accessible to earlier versions of Swift.
- Closed a bug where ssync may have written bad fragment data in
some circumstances. A check was added to ensure the correct number
of bytes is written for a fragment before finalizing the write.
Also, erasure coded fragment metadata will now be validated on read
requests and, if bad data is found, the fragment will be quarantined.
- The improvements to EC reads made in Swift 2.10.0 have also been
applied to the reconstructor. This allows fragments to be rebuilt
in more circumstances, resulting in faster recovery from failures.
- WARNING: If you are using the ISA-L library for erasure codes,
please upgrade to liberasurecode 1.3.1 (or later) as soon as
possible. If you are using isa_l_rs_vand with more than 4 parity,
please read https://bugs.launchpad.net/swift/+bug/1639691 and take
necessary action.
-------------------------------------------------------------------
Sat Sep 24 01:17:48 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.9.1.dev281:
swift (2.10.0, OpenStack Newton)
* Object versioning now supports a "history" mode in addition to
the older "stack" mode. The difference is in how DELETE requests
are handled. For full details, please read
http://docs.openstack.org/developer/swift/overview_object_versioning.html.
* New config variables to change the schedule priority and I/O
scheduling class. Servers and daemons now understand
`nice_priority`, `ionice_class`, and `ionice_priority` to
schedule their relative importance. Please read
http://docs.openstack.org/developer/swift/deployment_guide.html
for full config details.
* On newer kernels (3.15+ when using xfs), Swift will use the O_TMPFILE
flag when opening a file instead of creating a temporary file
and renaming it on commit. This makes the data path simpler and
allows the filesystem to more efficiently optimize the files on
disk, resulting in better performance.
* Erasure code GET performance has been significantly
improved in clusters that are not completely healthy.
* Significant improvements to the api-ref doc available at
http://developer.openstack.org/api-ref/object-storage/.
* A PUT or POST to a container will now update the container's
Last-Modified time, and that value will be included in a
GET/HEAD response.
-------------------------------------------------------------------
Wed Sep 21 13:08:51 UTC 2016 - mjura@suse.com
- Update to version 2.9.1.dev270

- Update to version 2.9.1.dev209
-------------------------------------------------------------------
Thu Jul 14 02:28:09 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.8.1.dev93:
swift (2.9.0)
* Swift now supports at-rest encryption. This feature encrypts all
object data and user-set object metadata as it is sent to the cluster.
This feature is designed to prevent information leaks if a hard drive
leaves the cluster. The encryption is transparent to the end-user.
At-rest encryption in Swift is enabled on the proxy server by
adding two middlewares to the pipeline. The `keymaster` middleware
is responsible for managing the encryption keys and the `encryption`
middleware does the actual encryption and decryption.
Existing clusters will continue to work without enabling
encryption. Although enabling this feature on existing clusters
is supported, best practice is to enable this feature on new
clusters when the cluster is created.
For more information on the details of the at-rest encryption
feature, please see the docs at
http://docs.openstack.org/developer/swift/overview_encryption.html.
* `swift-recon` can now be called with more than one server type.
* Fixed a bug where non-ascii names could cause an error in logging
and cause a 5xx response to the client.
* The install guide and API reference have been moved into Swift's
source code repository.
* Various other minor bug fixes and improvements.
-------------------------------------------------------------------
Tue Jun 7 23:48:30 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.7.1.dev184:
swift (2.8.0)
* Allow concurrent bulk deletes for server-side deletes of static
large objects. Previously this would be single-threaded and each
DELETE executed serially. The new `delete_concurrency` value
(default value is 2) in the `[filter:slo]` and `[filter:bulk]`
sections of the proxy server config controls the concurrency
used to perform the DELETE requests for referenced segments. The
default value is recommended, but setting the value to 1
restores previous behavior.
* Refactor server-side copy as middleware
The COPY verb is now implemented in the `copy` middleware instead
of in the proxy server code. If not explicitly added, the server
side copy middleware is auto-inserted to the left of `dlo`, `slo`
and `versioned_writes` middlewares in the proxy server pipeline.
As a result, dlo and slo `copy_hooks` are no longer required. SLO
manifests are now validated when copied so when copying a
manifest to another account the referenced segments must be
readable in that account for the manifest copy to succeed
(previously this validation was not made, meaning the manifest
was copied but could be unusable if the segments were not
readable).
With this change, there should be no change in functionality or
existing behavior.
* `fallocate_reserve` can now be a percentage (a value ending in "%"),
and the default has been adjusted to "1%".
-------------------------------------------------------------------
Thu Mar 24 13:39:56 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.6.1.dev262:
swift (2.7.0, OpenStack Mitaka)
* Bump PyECLib requirement to >= 1.2.0
* Update container on fast-POST
"Fast-POST" is the mode where `object_post_as_copy` is set to
`False` in the proxy server config. This mode now allows for
fast, efficient updates of metadata without needing to fully
recopy the contents of the object. While the default still is
`object_post_as_copy` as True, the plan is to change the default
to False and then deprecate post-as-copy functionality in later
releases. Fast-POST now supports container-sync functionality.
* Add concurrent reads option to proxy.
This change adds 2 new parameters to enable and control concurrent
GETs in Swift, these are `concurrent_gets` and `concurrency_timeout`.
`concurrent_gets` allows you to turn on or off concurrent
GETs; when on, it will set the GET/HEAD concurrency to the
replica count. And in the case of EC HEADs it will set it to
ndata. The proxy will then serve only the first valid source to
respond. This applies to all account, container, and replicated
object GETs and HEADs. For EC only HEAD requests are affected.
The default for `concurrent_gets` is off.
`concurrency_timeout` is related to `concurrent_gets` and is
the amount of time to wait before firing the next thread. A
value of 0 will fire at the same time (fully concurrent), but
-------------------------------------------------------------------
Fri Feb 26 02:58:24 UTC 2016 - cloud-devel@suse.de
- Update to version swift-2.6.1.dev138:
swift (2.6.0)
* Dependency changes
- Updated minimum version of eventlet to 0.17.4 to support IPv6.
- Updated the minimum version of PyECLib to 1.0.7.
* The ring rebalancing algorithm was updated to better handle edge cases
and to give better (more balanced) rings in the general case. New rings
will have better initial placement, capacity adjustments will move less
data for better balance, and existing rings that were imbalanced should
start to become better balanced as they go through rebalance cycles.
* Added container and account reverse listings.
A GET request to an account or container resource with a "reverse=true"
query parameter will return the listing in reverse order. When
iterating over pages of reverse listings, the relative order of marker
and end_marker are swapped.
* Storage policies now support having more than one name.
This allows operators to fix a typo without breaking existing clients,
or, alternatively, have "short names" for policies. This is implemented
with the "aliases" config key in the storage policy config in
swift.conf. The aliases value is a list of names that the storage
policy may also be identified by. The storage policy "name" is used to
report the policy to users (eg in container headers). The aliases have
the same naming restrictions as the policy's primary name.
-------------------------------------------------------------------
Sun Oct 4 00:37:16 UTC 2015 - cloud-devel@suse.de
- Update to version swift-2.4.1.dev70:
swift (2.5.0, OpenStack Liberty)
* Added the ability to specify ranges for Static Large Object (SLO)
segments.
* Replicator configs now support an "rsync_module" value to allow
for per-device rsync modules. This setting gives operators the
ability to fine-tune replication traffic in a Swift cluster and
isolate replication disk IO to a particular device. Please see
the docs and sample config files for more information and
examples.
* Significant work has gone in to testing, fixing, and validating
Swift's erasure code support at different scales.
* Swift now emits StatsD metrics on a per-policy basis.
* Fixed an issue with Keystone integration where a COPY request to a
service account may have succeeded even if a service token was not
included in the request.
* Ring validation now warns if a placement partition gets assigned to the
same device multiple times. This happens when devices in the ring are
unbalanced (e.g. two servers where one server has significantly more
available capacity).
* Various other minor bug fixes and improvements.
-------------------------------------------------------------------
Wed Sep 2 00:18:26 UTC 2015 - cloud-devel@suse.de
- Update to version swift-2.3.1.dev356:
swift (2.4.0)
* Dependency changes
- Added six requirement. This is part of an ongoing effort to add
support for Python 3.
- Dropped support for Python 2.6.
* Config changes
- Recent versions of Python restrict the number of headers allowed in a
request to 100. This number may be too low for custom middleware. The
new "extra_header_count" config value in swift.conf can be used to
increase the number of headers allowed.
- Renamed "run_pause" setting to "interval" (current configs with
run_pause still work). Future versions of Swift may remove the
run_pause setting.
* Versioned writes middleware
The versioned writes feature has been refactored and reimplemented as
middleware. You should explicitly add the versioned_writes middleware to
your proxy pipeline, but do not remove or disable the existing container
server config setting ("allow_versions"), if it is currently enabled.
The existing container server config setting enables existing
containers to continue being versioned. Please see
http://swift.openstack.org/middleware.html#how-to-enable-object-versioning-in-a-swift-cluster
for further upgrade notes.

Mon May 4 09:38:24 UTC 2015 - vuntz@opensuse.org
- Update to version swift-2.3.1.dev12:
swift (2.3.0)
* Erasure Code support (beta)
Swift now supports an erasure-code (EC) storage policy type. This allows
deployers to achieve very high durability with less raw capacity as used
in replicated storage. However, EC requires more CPU and network
resources, so it is not good for every use case. EC is great for storing
large, infrequently accessed data in a single region.
Swift's implementation of erasure codes is meant to be transparent to
end users. There is no API difference between replicated storage and
EC storage.
To support erasure codes, Swift now depends on PyECLib and
liberasurecode. liberasurecode is a pluggable library that allows for
the actual EC algorithm to be implemented in a library of your choosing.
As a beta release, EC support is nearly fully feature complete, but it
is lacking support for some features (like multi-range reads) and has
not had a full performance characterization. This feature relies on
ssync for durability. Deployers are urged to do extensive testing and
not deploy production data using an erasure code storage policy.
Full docs are at http://swift.openstack.org/overview_erasure_code.html
* Add support for container TempURL Keys.
* Make more memcache options configurable. connection_timeout,
pool_timeout, tries, and io_timeout are all now configurable.

- Update to version swift-2.2.2rc1.post9:
swift (2.2.2)
* Data placement changes
This release has several major changes to data placement in Swift in
order to better handle different deployment patterns. First, with an
unbalance-able ring, less partitions will move if the movement doesn't
result in any better dispersion across failure domains. Also, empty
(partition weight of zero) devices will no longer keep partitions after
rebalancing when there is an unbalance-able ring.
Second, the notion of "overload" has been added to Swift's rings. This
allows devices to take some extra partitions (more than would normally
be allowed by the device weight) so that smaller and unbalanced clusters
will have less data movement between servers, zones, or regions if there
is a failure in the cluster.
Finally, rings have a new metric called "dispersion". This is the
percentage of partitions in the ring that have too many replicas in a
particular failure domain. For example, if you have three servers in a
cluster but two replicas for a partition get placed onto the same
server, that partition will count towards the dispersion metric. A
lower value is better, and the value can be used to find the proper
value for "overload".
The overload and dispersion metrics have been exposed in the
swift-ring-build CLI tools.
See http://docs.openstack.org/developer/swift/overview_ring.html
for more info on how data placement works now.

Tue Dec 16 00:52:18 UTC 2014 - cloud-devel@suse.de
- Update to version swift-2.2.1c1.2.g8bbb50d:
swift (2.2.1)
* Swift now rejects object names with Unicode surrogates.
* Return 403 (instead of 413) on unauthorized upload when over account
quota.
* Fix a rare condition when a rebalance could cause swift-ring-builder
to crash. This would only happen on old ring files when "rebalance"
was the first command run.
* Storage node error limits now survive a ring reload.
* Speed up reading and writing xattrs for object metadata by using larger
xattr value sizes. The change is moving from 254 byte values to 64KiB
values. There is no migration issue with this.
* Deleted containers beyond the reclaim age are now properly reclaimed.
* Full Simplified Chinese translation (zh_CN locale) for errors and logs.
* Container quota is now properly enforced during cross-account COPY.
* ssync replication now properly uses the configured replication_ip.
* Fixed issue were ssync did not replicate custom object headers.
* swift-drive-audit now has the 'unmount_failed_device' config option
(default to True) that controls if the process will unmount failed
drives or not.
-------------------------------------------------------------------
Sat Oct 4 23:58:17 UTC 2014 - cloud-devel@suse.de
- Update to version swift-2.1.0.126.g94fd95b:
swift (2.2.0)
* Added support for Keystone v3 auth.
Keystone v3 introduced the concept of "domains" and user names
are no longer unique across domains. Swift's Keystone integration
now requires that ACLs be set on IDs, which are unique across
domains, and further restricts setting new ACLs to only use IDs.
Please see http://swift.openstack.org/overview_auth.html for
more information on configuring Swift and Keystone together.
* Swift now supports server-side account-to-account copy. Server-
side copy in Swift requires the X-Copy-From header (on a PUT)
or the Destination header (on a COPY). To initiate an account-to-
account copy, the existing header value remains the same, but the
X-Copy-From-Account header (on a PUT) or the Destination-Account
(on a COPY) are used to indicate the proper account.
* Limit partition movement when adding a new placement tier.
When adding a new placement tier (server, zone, or region), Swift
previously attempted to move all placement partitions, regardless
of the space available on the new tier, to ensure the best possible
durability. Unfortunately, this could result in too many partitions
being moved all at once to a new tier. Swift's ring-builder now
ensures that only the correct number of placement partitions are
rebalanced, and thus makes adding capacity to the cluster more
efficient.
-------------------------------------------------------------------
Sun Aug 24 00:01:27 UTC 2014 - cloud-devel@suse.de
- Update to version swift-2.0.0.148.g8d02147:
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.
-------------------------------------------------------------------
Fri Jun 27 08:37:01 UTC 2014 - dmueller@suse.com
- Update to version swift-2.0.0.rc1.12.g53577c5:
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.
-------------------------------------------------------------------
Fri Apr 4 08:20:51 UTC 2014 - cloud-devel@suse.de
- Update to version swift-1.13.0.116.gbf292ae:
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.

- Update to version swift-1.12.0.111.g58fda94:
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.
