      I have attached a repro; it prints out the oplogs showing two dropDatabase entries in a row (and no createDatabase) for the affected database.

      I have attached a repro; it prints out the oplogs showing two dropDatabase entries in a row (and no createDatabase) for the affected database.

    Description

      If we run enableSharding and movePrimary on a database, we can cause it to be created (for the purpose of dropDatabase) without a "create" oplog entry. It appears that on the primary shard this does not cause a problem. On a non-primary shard the database will be created on the primary but not the secondary, so if a dropDatabase is run, it will create an oplog entry to delete a database the secondary does not think exists.
