      Show
      db.a.insert({'a':1}) show collections db.system.namespace.find() show collections shows the created collection system.namespaces.find() does not

      Running mongod-2.8.0-rc1-pre- I find that the db.system.namespaces collection is not showing existing collection:

      nair(mongod-2.8.0-rc1-pre-) MongoMKDB> show collections
blobs               4.433MB / 4.113MB
nair(mongod-2.8.0-rc1-pre-) MongoMKDB> db.system.namespaces.count()
0
nair(mongod-2.8.0-rc1-pre-) MongoMKDB> db.system.namespaces.find()
Fetched 0 record(s) in 0ms

      I found this through running some tests with the java driver (and other drivers do the same) who pings the database on system.namespaces to find all existing collections.
