      Description

      Forgetting that MongoDB doesn't allow periods in database names, I used the dot notation in an attempt to create a namespaced database during a recovery operation:

      mongorestore -h recoveryhost --port 27018 -d myproj.recovered .\dump\myproj
      connected to: recoveryhost:27018
      Tue Feb 18 08:02:49.206 .\dump\myproj\cases.bson
      Tue Feb 18 08:02:49.207         going into namespace [myproj.recovered.cases]

      assertion: 13106 nextSafe(): { $err: "bad or malformed command request?", code: 13530 }

      As you can see, using the period in the name caused the cases to be restored to the recovered.cases collection on the myproj database.

      As it turns out, this isn't a big deal, but it came as a surprise and could have been a big deal if 'recovered.cases' had already existed in the 'myproj' database.

      I suggest mongorestore should reject a database name with a period in it.
