// SERVER-7720 Building an index with a too-long name should always fail
// Formerly, we would allow an index that already existed to be "created" with too long a name,
// but this caused secondaries to crash when replicating what should be a bad createIndex command.
// Here we test that the too-long name is rejected in this situation as well
