You should be able to run: `python3 testing.py` to get started. Note that the first time you run it, it will create the two files `relation1` and `logfile`, but after you kill it, the logfile will be inconsistent (we never write out CHECKPOINT records in normal course). So the second time you run it, it will error out since the restartRecovery code is not implemented. So if you want to work on the other two tasks, you should remove those two files every time. -- GitLab
