As mentioned in this issue (PaulLockett#8). I think there is a bug in the test file for level 4. This is the order of operations: ["FILE_UPLOAD_AT", "2021-07-01T12:00:00", "Initial.txt", "100kb"], ["FILE_UPLOAD_AT", "2021-07-01T12:05:00", "Update1.txt", "150kb", 3600], ["FILE_GET_AT", "2021-07-01T12:10:00", "Initial.txt"], ["FILE_COPY_AT", "2021-07-01T12:15:00", "Update1.txt", "Update1Copy.txt"], ["FILE_UPLOAD_AT", "2021-07-01T12:20:00", "Update2.txt", "200kb", 1800], ["ROLLBACK", "2021-07-01T12:10:00"], ["FILE_GET_AT", "2021-07-01T12:25:00", "Update1.txt"], ["FILE_GET_AT", "2021-07-01T12:25:00", "Initial.txt"], ["FILE_SEARCH_AT", "2021-07-01T12:25:00", "Up"], ["FILE_GET_AT", "2021-07-01T12:25:00", "Update2.txt"]

After step 6 (ROLLBACK), the file
Update2.txtshould not exist because it was uploaded at2021-07-01T12:20:00, which is after the rollback timestamp2021-07-01T12:10:00.Since the system is rolled back to the state as of
2021-07-01T12:10:00, any files uploaded after this timestamp should no longer exist. However, the test case appears to assumeUpdate2.txtis still accessible after the rollback, which contradicts the expected behavior.
