OpenStack Storage (Swift)

Serialize RingData in a versioned, custom format which is a combination of a JSON-encoded header and .tostring() dumps of the replica2part2dev_id arrays. This format deserializes hundreds of times faster than rings serialized with Python 2.7's pickle (a significant performance regression for ring loading between Python 2.6 and Python 2.7). Fixes bug 1031954. swift.common.ring.ring.RingData is now responsible for serialization and deserialization of its data via a new load() class method and save() object method. The new implementation is backward-compatible; if a ring does not begin with a new-style magic string, it is assumed to be an old-style pickle-dumped ring and is handled as before. So new Swift code can read old rings, but old Swift code will not be able to read newly-serialized rings. THIS SHOULD BE MENTIONED PROMINENTLY IN THE RELEASE NOTES. I didn't want to bite of more than necessary, so I didn't mess with builder file serialization. Change-Id: I799b9a4c894d54fb16592443904ac055b2638e2d |

Swift ----- A distributed object store that was originally developed as the basis for Rackspace's Cloud Files. To build documentation run `python setup.py build_sphinx`, and then browse to /doc/build/html/index.html. The best place to get started is the "SAIO - Swift All In One", which will walk you through setting up a development cluster of Swift in a VM. For more information, visit us at http://launchpad.net/swift, or come hang out on our IRC channel, #openstack on freenode. -- Swift Development Team
