| |
| Whenever a retry job is complete, we want to invalidate the original |
| job's test results, such that the consumers of the tko database |
| (e.g. tko frontend, wmatrix) could figure out which results are the latest. |
| |
| When a retry job is parsed, we retrieve the original job's afe_job_id |
| from the retry job's keyvals, which is then converted to tko job_idx and |
| passed into this method as |orig_job_idx|. |
| |
| In this method, we are going to invalidate the rows in tko_tests that are |
| associated with the original job by flipping their 'invalid' bit to True. |
| In addition, in tko_tests, we also maintain a pointer from the retry results |
| to the original results, so that later we can always know which rows in |
| tko_tests are retries and which are the corresponding original results. |
| This is done by setting the field 'invalidates_test_idx' of the tests |
| associated with the retry job. |
| |
| For example, assume Job(job_idx=105) are retried by Job(job_idx=108), after |
| this method is run, their tko_tests rows will look like: |
| __________________________________________________________________________ |
| test_idx| job_idx | test | ... | invalid | invalidates_test_idx |
| 10 | 105 | dummy_Fail.Error| ... | 1 | NULL |
| 11 | 105 | dummy_Fail.Fail | ... | 1 | NULL |
| ... |
| 20 | 108 | dummy_Fail.Error| ... | 0 | 10 |
| 21 | 108 | dummy_Fail.Fail | ... | 0 | 11 |
| __________________________________________________________________________ |
| Note the invalid bits of the rows for Job(job_idx=105) are set to '1'. |
| And the 'invalidates_test_idx' fields of the rows for Job(job_idx=108) |
| are set to 10 and 11 (the test_idx of the rows for the original job). |
| |
| @param orig_job_idx: An integer representing the original job's |
| tko job_idx. Tests associated with this job will |
| be marked as 'invalid'. |
