2.10.2
^^^^^^

Bug Fixes

* Improvements in key parts of the consistency engine - 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.

  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.

* 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.

* 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.

* Correctly send 412 Precondition Failed if a user sends an invalid
  copy destination. Previously Swift would send a 500 Internal Server
  Error.

* 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.

* Account and container databases will now be quarantined if the
  database schema has been corrupted.

* Ensure update of the container by object-updater, removing a rare
  possibility that objects would never be added to a container
  listing.

* Fixed some minor test compatibility issues.

* Updated docs to reference appropriate ports.
