fixes:
- |
Sharding improvements:
* Prevent object updates from auto-creating shard containers. This
ensures more consistent listings for sharded containers during
rebalances.
* Deleted shard containers are no longer considered root containers.
This prevents unnecessary sharding audit failures and allows the
deleted shard database to actually be unlinked.
* The sharder daemon has been enhanced to better support the shrinking
of shards that are no longer required. Shard containers will now
discover from their root container if they should be shrinking. They
will also discover the shards into which they should shrink, which may
include the root container itself.
* Improved performance of sharded container listings when performing
prefix listings.
* Improved container-sharder stat reporting to reduce load on root
container databases.
* The container sharder can now handle containers with special
characters in their names.
* ``swift-container-info`` now summarizes shard range information.
Pass ``-v``/``--verbose`` if you want to see all of them.
* Don't inject shard ranges when user quits.
* Various other minor bug fixes and improvements.
