Swift's Keystone integration + now requires that ACLs be set on IDs, which are unique across + domains, and further restricts setting new ACLs to only use IDs. + + Please see http://swift.openstack.org/overview_auth.html for + more information on configuring Swift and Keystone together. + + * Swift now supports server-side account-to-account copy. Server- + side copy in Swift requires the X-Copy-From header (on a PUT) + or the Destination header (on a COPY). To initiate an account-to- + account copy, the existing header value remains the same, but the + X-Copy-From-Account header (on a PUT) or the Destination-Account + (on a COPY) are used to indicate the proper account. + + * Limit partition movement when adding a new placement tier. + + When adding a new placement tier (server, zone, or region), Swift + previously attempted to move all placement partitions, regardless + of the space available on the new tier, to ensure the best possible + durability. Unfortunately, this could result in too many partitions + being moved all at once to a new tier. Swift's ring-builder now + ensures that only the correct number of placement partitions are + rebalanced, and thus makes adding capacity to the cluster more + efficient. + + * Per storage policy container counts are now reported in an + account response headers. + + * Swift will now reject, with a 4xx series response, GET requests + with more than 50 ranges, more than 3 overlapping ranges, or more + than 8 non-increasing ranges. + + * The bind_port config setting is now required to be explicitly set. + + * The object server can now use splice() for a zero-copy GET + response. This feature is enabled with the "splice" config variable + in the object server config and defaults to off. Also, this feature + only works on recent Linux kernels (AF_ALG sockets must be + supported). A zero-copy GET response can significantly reduce CPU + requirements for object servers. + + * Added "--no-overlap" option to swift-dispersion populate so that + multiple runs of the tool can add coverage without overlapping + existing monitored partitions. + + * swift-recon now supports filtering by region. + + * Various other minor bug fixes and improvements. + swift (2.1.0) * swift-ring-builder placement was improved to allow gradual addition |
