MogileFS 2.32 - Changelog

What's new in MogileFS 2.30:

July 28th, 2009

· fsck will now fix broken 'devcount' cols.
· schema version bump to 12, and new delete worker code to use the new queue system. delete should be faster and more scalable.
· add server setting queue_rate_for_fsck to allow rate limiting how fast the new distributed fsck creates jobs. the original default of 10k could utterly defeat wimpy databases.
· Support 0 byte files.
· Fix a bug where rebalance would accidentally delete copies of a fid.
· Create new internal queue management system, with new job 'JobMaster'. This greatly reduces database load and increases throughput for workers using the new system.
· Add 'no_unreachable_tracking' config. Disables more of the old replication code. Use this if you have no 1.x trackers.
· Add hook for alternate replication sources. Obscure, but can be nice.
· Add replicate_order_final_choices hook, so multidc replication may pull from the local network if one copy already exists.
· Fix subtle bugs in process management.
· Allow overriding of default classes.
