We are thrilled to announce the release of: swift 2.10.2: OpenStack Object Storage This release is part of the newton stable release series. Download the package from: https://tarballs.openstack.org/swift/ For more details, please see below. 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.
