| """A module handling the logs. |
| |
| The structure of this module: |
| |
| RoundLog: the test results of every round are saved in a log file. |
| includes: fw, and round_name (i.e., the date time of the round |
| |
| --> GestureLogs: includes gesture name, and variation |
| |
| --> ValidatorLogs: includes name, details, criteria, score, metrics |
| |
| |
| SummaryLog: derived from multiple RoundLogs |
| --> SimpleTable: (key, vlog) pairs |
| key: (fw, round_name, gesture_name, variation_name, validator_name) |
| vlog: name, details, criteria, score, metrics |
| |
| TestResult: encapsulation of scores and metrics |
| used by a client program to query the test results |
| --> StatisticsScores: includes average, ssd, and count |
| --> StatisticsMetrics: includes average, min, max, and more |
| |
| |
| How the logs work: |
| (1) ValidatorLogs are contained in a GestureLog. |
| (2) Multiple GestureLogs are packed in a RoundLog which is saved in a |
| separate pickle log file. |
| (3) To construct a SummaryLog, it reads RoundLogs from all pickle logs |
| in the specified log directory. It then creates a SimpleTable |
| consisting of (key, ValidatorLog) pairs, where |
| key is a 5-tuple: |
| (fw, round_name, gesture_name, variation_name, validator_name). |
| (4) The client program, i.e., firmware_summary module, contains a |
| SummaryLog, and queries all statistics using get_result() which returns |
| a TestResult object containing both StatisticsScores and |
| StatisticsMetrics. |
