      Currently all operations specified in update are applied for update and upsert, and $setOnInsert only applies operations on insert/upsert.

      This request is to add a $setOnUpdate for operations that would be applied only on update (and not on upsert/insert) and possibly analogously $incOnUpdate. This would allow handling many of the use cases described in SERVER-2643 and SERVER-10711 (and possibly some others).

      Syntax might need to be different as "on update" all operations, not just $set might need to be accessible. Possible example:

      db.collection.update({_id:297},
      { $set:{updatedAt:"$currentTime"},
        $setOnInsert:{createdAt:"$currentTime",score:100},
        $setOnUpdate:{returnedAt:"$currentTime"},
        $incOnUpdate:{score:20}
     }, {upsert:true} );
