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may write a manifest that an out-of-date proxy server will not be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.
|
||||
|
||||
* Object expiry improvements
|
||||
|
||||
- Disallow X-Delete-At header values equal to the X-Timestamp header.
|
||||
|
||||
- X-Delete-At computation now uses X-Timestamp instead of
|
||||
system time. This prevents clock skew causing inconsistent
|
||||
expiry data.
|
||||
|
||||
- Deleting an expiring object will now cause less work in the system.
|
||||
The number of async pending files written has been reduced for all
|
||||
objects and greatly reduced for erasure-coded objects. This
|
||||
dramatically reduces the burden on container servers.
|
||||
|
||||
- Stopped logging tracebacks when receiving an unexpected response.
|
||||
|
||||
- Allow the expirer to gracefully move past updating stale work items.
|
||||
|
||||
* When the object auditor examines an object, it will now add any
|
||||
missing metadata checksums.
|
||||
|
||||
* `swift-ring-builder` improvements
|
||||
|
||||
- Save the ring when dispersion improves, even if balance
|
||||
doesn't improve.
|
||||
|
||||
- Improved the granularity of the ring dispersion metric so that
|
||||
small improvements after a rebalance can show changes in the
|
||||
dispersion number. Dispersion in existing and new rings can be
|
||||
recalculated using the new '--recalculate' option to
|
||||
`swift-ring-builder`.
|
||||
|
||||
- Display more info on empty rings.
|
||||
|
||||
* Fixed rare socket leak on range requests to erasure-coded objects.
|
||||
|
||||
* The number of container updates on object PUTs (ie to update listings)
|
||||
has been recomputed to be far more efficient while maintaining
|
||||
durability guarantees. Specifically, object PUTs to erasure-coded
|
||||
policies will now normally result in far fewer container updates.
|
||||
|
||||
* Moved Zuul v3 tox jobs into the Swift code repo.
|
||||
|
||||
* Changed where liberasurecode-devel for CentOS 7 is referenced and
|
||||
installed as a dependency.
|
||||
|
||||
* Added container/object listing with prefix to InternalClient.
|
||||
|
||||
* Added '--swift-versions' to `swift-recon` CLI to compare installed
|
||||
versions in the cluster.
|
||||
|
||||
* Stop logging tracebacks in the `object-replicator` when it runs
|
||||
out of handoff locations.
|
||||
|
||||
* Send ETag header in 206 Partial Content responses to SLO reads.
|
||||
|
||||
* Now `swift-recon-cron` works with conf.d configs.
|
||||
|
||||
* Improved `object-updater` stats logging. It now tells you all of
|
||||
its stats (successes, failures, quarantines due to bad pickles,
|
||||
unlinks, and errors), and it tells you incremental progress every
|
||||
five minutes. The logging at the end of a pass remains and has
|
||||
been expanded to also include all stats.
|
||||
|
||||
* If a proxy server is configured to autocreate accounts and the
|
||||
account create fails, it will now return a server error (500)
|
||||
instead of Not Found (404).
|
||||
|
||||
* Fractional replicas are no longer allowed for erasure code policies.
|
||||
|
||||
* Various other minor bug fixes and improvements.
|
||||
|
||||
|
||||
swift (2.16.0)
|
||||
|
||||
* Add checksum to object extended attributes.
