.Swift object expiration is no longer effected by resharding The Swift object expiration code was not compatible with bucket index resharding. This behavior could stall object expiration for the buckets. The Swift object expiration code has been updated to identify buckets using a tenant and bucket name. This update allows the removal of expired objects from an already resharded and stalled bucket. As a result, the object expiration is no longer effected by bucket index resharding.

Description Matt Benjamin (redhat) 2019-04-26 17:06:58 UTC 
From upstream tracker:
"""

A bucket reshard causes swift object expiry to fail. While further swift client requests will still return a 404 as we check for obj expiry times in GET requests, the object is never deleted on disk, and the delete hint is already trimmed as we assume a non-findeable bucket means the bucket was deleted

$ swift upload foobar foo -H "X-Delete-After: 100" 
$ radosgw-admin bucket reshard foobar --num-shards 4 
$ sleep 100 && radosgw-admin objects expire --debug-rgw=20
$ radosgw-admin object stat --bucket foobar --object foo # returns
