🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Consider failing when the locked prow_job_runs row is absent.
tx.Raw(... FOR UPDATE).Scan(¤tRun) returns no error when the row does not exist. In that case currentRun.Labels is empty and the following Update matches zero rows, so the label write is silently skipped and the caller still reports PostgresUpdated = true. A check on RowsAffected makes the outcome explicit.
🛡️ Proposed guard
- if err := tx.Raw(
+ res := tx.Raw(
"SELECT labels FROM prow_job_runs WHERE id = ? AND prow_job_release = ? AND timestamp = ? FOR UPDATE",
- jobRun.ID, jobRun.ProwJobRelease, jobRun.Timestamp).Scan(¤tRun).Error; err != nil {
- return fmt.Errorf("locking prow_job_runs row for build %s: %w", buildID, err)

+ if res.Error != nil {

This file is no longer in this PR's diff — reevaluate.go was part of Phase 1 (#3922, now merged into main). This PR was rebased to contain only the Phase 2 backfill command.
The finding is valid: when the prow_job_runs row is absent, Scan returns no error and the subsequent Update silently matches zero rows. I'll track this as a follow-up improvement on the Phase 1 code in main.

@mstaeble, understood. This finding applies to the Phase 1 code on main, not to this PR.

The `updatePostgresLabels` transaction should eventually treat an absent locked `prow_job_runs` row as an error because GORM `Scan` can return no error with zero rows and the subsequent update can silently affect zero rows.

- Around line 530-550: Add a regression test covering the zero-row lock path in
updatePostgresLabels: when prow_job_runs is missing, assert the method succeeds,
skips summary subtraction, and leaves release_job_runs unchanged.
In `@pkg/db/query/test_queries.go`:
- Around line 469-475: Update TestDurations to retain civil.Date for scanning
but return string-keyed results using row.Period.String(), ensuring the map is
JSON-serializable; in pkg/db/query/test_queries.go lines 469-475, change the
returned map construction accordingly, and in pkg/api/tests.go line 208, convert
keys to strings if the handler still serializes the result directly.

Add a management CLI command that backfills InfraFailure job run labels from BigQuery into PostgreSQL, the phase 2 companion to the write/read-time exclusion added in phase 1. The command reads runs labeled InfraFailure from the BigQuery job_labels table within a configurable time window (--since date or --days lookback, default 90) and, for each run missing the label in PostgreSQL, calls infrafailure.RecordInfraFailure to atomically apply the label and subtract the run's contribution from the summary tables. RecordInfraFailure is idempotent, so the backfill is safe to run repeatedly. The core logic lives in pkg/dataloader/infrafailurebackfill so the pure pieces (window resolution, query construction, batching, classification) are unit-testable without clients; the narrow BigQuery and PostgreSQL calls sit behind function fields exercised via closures and a credential-gated functional test. The cmd file just wires up clients and delegates. Flags: --since, --days, --dry-run, --batch-size, composed with the standard Postgres, BigQuery, and Google Cloud flag sets (mirroring the load command). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Align TestDurations (and its GetTestDurationsFromDB caller) with the civil.Date map key introduced on main so the InfraFailure integration tests compile after the PR is merged, and key the read-time exclusion test's durations lookup by civil.Date. CodeRabbit follow-ups: - backfill-infra-failures: wrap errors with fmt.Errorf %w instead of github.com/pkg/errors. - infrafailurebackfill: validate the BigQuery dataset against an allow-list before interpolating it into the query (SQL injection), and size the batch slice with overflow-safe ceiling division. - reevaluate: check RowsAffected after the SELECT ... FOR UPDATE lock and skip the label update when the prow_job_runs row is missing rather than proceeding with empty data. - test_queries: document why the read-time output/duration queries exclude InfraFailure-labeled runs. - infrafailure: add RecordInfraFailureWithOutcome to distinguish newly labeled, already-labeled, and not-found runs so the backfill reports accurate stats; RecordInfraFailure remains a thin wrapper. Tests: - command-level flag-default test for backfill-infra-failures. - unit coverage for dataset validation and outcome-based reclassification. - integration coverage for SubtractNewInfraFailure across both summary tables and for re-evaluation preserving the InfraFailure label.

Resolve the remaining CodeRabbit findings and the QF1011 lint failure on the InfraFailure backfill: - backfill_test.go: drop the redundant "var _ []bigquery.QueryParameter" type assertion (QF1011) and the now-unused bigquery import; the test already validates the params contents directly. - backfill.go: check ctx.Err() at the top of the per-run loop so the backfill responds promptly to cancellation. - infrafailure.go: reserve OutcomeUnknown as the zero value of RecordOutcome so an uninitialized or error-path value never matches a meaningful outcome; add a documented String() method; return OutcomeUnknown on the error paths. - infrafailure.go: wrap the transaction error in RecordInfraFailureWithOutcome with run context via %w. - Avoid logging raw DB/BigQuery driver errors, which can embed hosts or credentials: return generic messages on client init failure and keep the per-run error detail at Debug level only. - Add doc comments to the exported symbols in backfill_infra_failures.go. - Add unit tests for the RecordOutcome constants and String().

I'm going to pitch including release here again. We should really only want to to do this for non ga releases and with the release clustering it would make sense as well.
There was a problem hiding this comment.
Ah, yes. I forgot about adding that after we discussed it.

Although, thinking about it more, is there any benefit to release clustering? The BigQuery tables are not partitioned by release, so we are not saving anything on that end by limiting it to specific releases.

Nevermind, I was confusing this with the junit table that is clustered by release
| Table("prow_job_runs"). | ||
| Select("id, (labels @> ARRAY['InfraFailure']) AS labeled"). | ||
| Where("id IN ?", batch). | ||
| Scan(&rows).Error |

This is going to be problematic once we partition. How long do you think we need to support this? You still have a pre-partition migration window so we could just note it will be problematic later and either leave it since it will be external or rework it as needed.
There was a problem hiding this comment.
Yes, it will be. When the ID-to-partition table is in place, we can switch this to an initial batch lookup for partition keys first. We can then see whether this will need to be a loop in the application code, or whether the planner can do the lookup effectively. Best case, with PG 18, we don't need special handling.
But this is only temporary, too. I don't know how long it will take to land the automatic label handling. I suspect partitioning of the table will land first.

Although, with that said, this is a manually action run by the engineering team, so it is not catastrophic if it is terribly, terribly inefficient.
