    Description

      The logic in http://review.couchbase.org/#/c/88301/17/engines/ep/src/checkpoint.cc is flawed and can allow a tombstone to be created with

      • A delete time in the past, which could be immediately purged causing issues as seen in the linked CBSE.
      • A delete time in the future, which allows the tombstone to remain on disk for potentially a long time.

      We should be more robust and set the delete-time to be ep_real_time at the point of deletion.
