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
parity should be migrated as soon as possible. Please see
https://bugs.launchpad.net/swift/+bug/1639691 for more information.
* The erasure code reconstructor `handoffs_first` option has been
deprecated in favor of `handoffs_only`. `handoffs_only` is far more
useful, and just like `handoffs_first` mode in the replicator, it gives
the operator the option of forcing the consistency engine to focus
solely on revert (handoff) jobs, thus improving the speed of
rebalances. The `handoffs_only` behavior is somewhat consistent with
the replicator's `handoffs_first` option (any error on any handoff in
the replicator will make it essentially handoff only forever) but the
`handoff_only` option does what you want and is named correctly in the
reconstructor.
* The default for `object_post_as_copy` has been changed to False. The
option is now deprecated and will be removed in a future release. If
your cluster is still running with post-as-copy enabled, please update
it to use the "fast-post" method. Future versions of Swift will not
support post-as-copy, and future features will not be supported under
post-as-copy. ("Fast-post" is where `object_post_as_copy` is false).
* Temporary URLs now support one common form of ISO 8601 timestamps in
addition to Unix seconds-since-epoch timestamps. The ISO 8601 format
accepted is '%Y-%m-%dT%H:%M:%SZ'. This makes TempURLs more
user-friendly to produce and consume.
* Listing containers in accounts with json or xml now includes a
`last_modified` time. This does not change any on-disk data, but simply
exposes the value to offer consistency with the object listings on
containers.
* Fixed a bug where the ring builder would not allow removal of a device
when min_part_seconds_left was greater than zero.
* PUT subrequests generated from a client-side COPY will now properly log
the SSC (server-side copy) Swift source field. See
https://docs.openstack.org/developer/swift/logs.html#swift-source for
more information.
* Fixed a bug where an SLO download with a range request may have resulted
in a 5xx series response.
* SLO manifest PUT requests can now be properly validated by sending an
ETag header of the md5 sum of the concatenated md5 sums of the
referenced segments.
* Fixed the stats calculation in the erasure code reconstructor.
* Rings with min_part_hours set to zero will now only move one partition
replica per rebalance, thus matching behavior when min_part_hours is
greater than zero.
* I/O priority is now supported on AArch64 architecture.
* Various other minor bug fixes and improvements.
swift (2.12.0)
* Ring files now include byteorder information about the endian of
