CHANGELOG

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
setting another value will stagger the firing allowing you the
ability to give a node a short chance to respond before firing
the next. This value is a float and should be somewhere between
0 and `node_timeout`. The default is `conn_timeout`, meaning by
default it will stagger the firing.
* Added an operational procedures guide to the docs. It can be
found at http://swift.openstack.org/ops_runbook/index.html and
includes information on detecting and handling day-to-day
operational issues in a Swift cluster.
* Make `handoffs_first` a more useful mode for the object replicator.
The `handoffs_first` replication mode is used during periods of
problematic cluster behavior (e.g. full disks) when replication
needs to quickly drain partitions from a handoff node and move
them to a primary node.
Previously, `handoffs_first` would sort that handoff work before
"normal" replication jobs, but the normal replication work could
take quite some time and result in handoffs not being drained
quickly enough.
In order to focus on getting handoff partitions off the node
`handoffs_first` mode will now abort the current replication
sweep before attempting any primary suffix syncing if any of the
handoff partitions were not removed for any reason - and start
over with replication of handoffs jobs as the highest priority.
Note that `handoffs_first` being enabled will emit a warning on
start up, even if no handoff jobs fail, because of the negative
impact it can have during normal operations by dog-piling on a
node that was temporarily unavailable.
* By default, inbound `X-Timestamp` headers are now disallowed
(except when in an authorized container-sync request). This
header is useful for allowing data migration from other storage
systems to Swift and keeping the original timestamp of the data.
If you have this migration use case (or any other requirement on
allowing the clients to set an object's timestamp), set the
`shunt_inbound_x_timestamp` config variable to False in the
gatekeeper middleware config section of the proxy server config.
* Requesting a SLO manifest file with the query parameters
"?multipart-manifest=get&format=raw" will return the contents of
the manifest in the format as was originally sent by the client.
The "format=raw" is new.
* Static web page listings can now be rendered with a custom
label. By default listings are rendered with a label of:
"Listing of /v1/<account>/<container>/<path>". This change adds
a new custom metadata key/value pair
`X-Container-Meta-Web-Listings-Label: My Label` that when set,
will cause the following: "Listing of My Label/<path>" to be
rendered instead.
* Previously, static large objects (SLOs) had a minimum segment
size (default to 1MiB). This limit has been removed, but small
segments will be ratelimited. The config parameter
`rate_limit_under_size` controls the definition of "small"
segments (1MiB by default), and `rate_limit_segments_per_sec`
controls how many segments per second can be served (default is 1).
With the default values, the effective behavior is identical to the
previous behavior when serving SLOs.
* Container sync has been improved to perform a HEAD on the remote
side of the sync for each object being synced. If the object
exists on the remote side, container-sync will no longer
transfer the object, thus significantly lowering the network
requirements to use the feature.
* The object auditor will now clean up any old, stale rsync temp
files that it finds. These rsync temp files are left if the
rsync process fails without completing a full transfer of an
object. Since these files can be large, the temp files may end
up filling a disk. The new auditor functionality will reap these
rsync temp files if they are old. The new object-auditor config
variable `rsync_tempfile_timeout` is the number of seconds old a
tempfile must be before it is reaped. By default, this variable
is set to "auto" or the rsync_timeout plus 900 seconds (falling
back to a value of 1 day).
* The Erasure Code reconstruction process has been made more
efficient by not syncing data files when only the durable commit
file is missing.
* Fixed a bug where 304 and 416 response may not have the right
Etag and Accept-Ranges headers when the object is stored in an
Erasure Coded policy.
* Versioned writes now correctly stores the date of previous versions
using GMT instead of local time.
* The deprecated Keystone middleware option is_admin has been removed.
* Fixed log format in object auditor.
* The zero-byte mode (ZBF) of the object auditor will now properly
observe the `--once` option.
* Swift keeps track, internally, of "dirty" parts of the partition
keyspace with a "hashes.pkl" file. Operations on this file no
longer require a read-modify-write cycle and use a new
"hashes.invalid" file to track dirty partitions. This change
will improve end-user performance for PUT and DELETE operations.
* The object replicator's succeeded and failed counts are now logged.
* `swift-recon` can now query hosts by storage policy.
* The log_statsd_host value can now be an IPv6 address or a hostname
which only resolves to an IPv6 address.
* Erasure coded fragments now properly call fallocate to reserve disk
space before being written.
* Various other minor bug fixes and improvements.
swift (2.6.0)
* Dependency changes
