|

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.
|
||||
|
||||
* Allow 1+ object-servers-per-disk deployment
|
||||
|
||||
Enabled by a new > 0 integer config value, "servers_per_port" in the
|
||||
[DEFAULT] config section for object-server and/or replication server
|
||||
configs. The setting's integer value determines how many different
|
||||
object-server workers handle requests for any single unique local port
|
||||
in the ring. In this mode, the parent swift-object-server process
|
||||
continues to run as the original user (i.e. root if low-port binding
|
||||
is required), binds to all ports as defined in the ring, and forks off
|
||||
the specified number of workers per listen socket. The child, per-port
|
||||
servers drop privileges and behave pretty much how object-server workers
|
||||
always have, except that because the ring has unique ports per disk, the
|
||||
object-servers will only be handling requests for a single disk. The
|
||||
parent process detects dead servers and restarts them (with the correct
|
||||
listen socket), starts missing servers when an updated ring file is
|
||||
found with a device on the server with a new port, and kills extraneous
|
||||
servers when their port is found to no longer be in the ring. The ring
|
||||
files are stat'ed at most every "ring_check_interval" seconds, as
|
||||
configured in the object-server config (same default of 15s).
|
||||
|
||||
In testing, this deployment configuration (with a value of 3) lowers
|
||||
request latency, improves requests per second, and isolates slow disk
|
||||
IO as compared to the existing "workers" setting. To use this, each
|
||||
device must be added to the ring using a different port.
|
||||
|
||||
* Do container listing updates in another (green)thread
|
||||
|
||||
The object server has learned the "container_update_timeout" setting
|
||||
(with a default of 1 second). This value is the number of seconds that
|
||||
the object server will wait for the container server to update the
|
||||
listing before returning the status of the object PUT operation.
|
||||
|
||||
Previously, the object server would wait up to 3 seconds for the
|
||||
container server response. The new behavior dramatically lowers object
|
||||
PUT latency when container servers in the cluster are busy (e.g. when
|
||||
the container is very large). Setting the value too low may result in a
|
||||
client PUT'ing an object and not being able to immediately find it in
|
||||
listings. Setting it too high will increase latency for clients when
|
||||
container servers are busy.
|
||||
|
||||
* TempURL fixes (closes CVE-2015-5223)
|
||||
|
||||
Do not allow PUT tempurls to create pointers to other data.
|
||||
Specifically, disallow the creation of DLO object manifests via a PUT
|
||||
tempurl. This prevents discoverability attacks which can use any PUT
|
||||
tempurl to probe for private data by creating a DLO object manifest and
|
||||
then using the PUT tempurl to head the object.
|
||||
|
||||
* Ring changes
|
||||
|
||||
- Partition placement no longer uses the port number to place
|
||||
partitions. This improves dispersion in small clusters running one
|
||||
object server per drive, and it does not affect dispersion in
|
||||
clusters running one object server per server.
|
||||
|
||||
- Added ring-builder-analyzer tool to more easily test and analyze a
|
||||
series of ring management operations.
|
||||
|
||||
- Stop moving partitions unnecessarily when overload is on.
|
||||
|
||||
* Significant improvements and bug fixes have been made to erasure code
|
||||
support. This feature is suitable for beta testing, but it is not yet
|
||||
ready for broad production usage.
|
||||
|
||||
* Bulk upload now treats user xattrs on files in the given archive as
|
||||
object metadata on the resulting created objects.
|
||||
|
||||
* Emit warning log in object replicator if "handoffs_first" or
|
||||
"handoff_delete" is set.
|
||||
|
||||
* Enable object replicator's failure count in swift-recon.
|
||||
|
||||
* Added storage policy support to dispersion tools.
|
||||
|
||||
* Support keystone v3 domains in swift-dispersion.
|
||||
|
||||
* Added domain_remap information to the /info endpoint.
|
||||
|
||||
* Added support for a "default_reseller_prefix" in domain_remap
|
||||
middleware config.
|
||||
|
||||
* Allow SLO PUTs to forgo per-segment integrity checks. Previously, each
|
||||
segment referenced in the manifest also needed the correct etag and
|
||||
bytes setting. These fields now allow the "null" value to skip those
|
||||
particular checks on the given segment.
|
||||
|
||||
* Allow rsync to use compression via a "rsync_compress" config. If set to
|
||||
true, compression is only enabled for an rsync to a device in a
|
||||
different region. In some cases, this can speed up cross-region
|
||||
replication data transfer.
|
||||
|
||||
* Added time synchronization check in swift-recon (the --time option).
|
||||
|
||||
* The account reaper now runs faster on large accounts.
|
||||
|
||||
* Various other minor bug fixes and improvements.
