    Description

      Description:

      The dbHash command now returns the names of any capped collections in a new "capped" field. The dbHash command also now returns the UUIDs associated with any collections in a new "uuids" field.

      Scope of changes:

      • 4.0
      • dbhash ref page
      • for now, won't reference in capped collections page since we tell people to use the isCapped() method to check if capped.

      Engineering Ticket Description:

      We should create another version of jstests/libs/override_methods/run_check_repl_dbhash.js and possibly of ReplSetTest#checkReplicatedDataHashes() that doesn't require (1) flushing background indexes with collMod operations, (2) fsync+locking the primary, and (3) call ReplSetTest#awaitReplication(). A background thread inside of resmoke.py should then run the "dbhash" command periodically via the hook file and cause the test to be marked as a failure if a data inconsistency is detected.
