From cc1d78210f27b94a9c78a35bf5b2dd384712aa4b Mon Sep 17 00:00:00 2001 From: szibis Date: Mon, 12 Oct 2026 10:16:18 +0200 Subject: [PATCH 01/32] fix: sum without over an unwrap range function keeps a series per remaining label set, like Loki `sum without (pod) (max_over_time({app="payment-service"} | logfmt | unwrap amount [5m]))` answered one series on query_range and at an instant, where Loki keeps every label but pod. The translation of an outer aggregation over an unwrap function, and of a sum over rate, ended in a stats pipe with no grouping, so VictoriaLogs returned one row and the without step had no labels to group by. The last stats pipe of an ` without (...)` now keeps the stream (the range aggregation's own grouping when it has one), VictoriaLogs answers a row per stream from stats, and the proxy drops the excluded labels and folds the rows with the outer operator, as Loki's VectorAggEvaluator does. --- .../unwrap-sum-without-collapses.yaml | 58 ++- .../proxy/sum_without_differential_test.go | 358 ++++++++++++++++++ internal/translator/translator.go | 42 +- internal/translator/without_grouping_test.go | 101 +++++ test/e2e-compat/unwrap_sum_without_test.go | 138 +++++++ 5 files changed, 687 insertions(+), 10 deletions(-) create mode 100644 internal/proxy/sum_without_differential_test.go create mode 100644 internal/translator/without_grouping_test.go create mode 100644 test/e2e-compat/unwrap_sum_without_test.go diff --git a/conformance/registry/cases/semantics/unwrap-sum-without-collapses.yaml b/conformance/registry/cases/semantics/unwrap-sum-without-collapses.yaml index 68004d2ea..1b31379d0 100644 --- a/conformance/registry/cases/semantics/unwrap-sum-without-collapses.yaml +++ b/conformance/registry/cases/semantics/unwrap-sum-without-collapses.yaml @@ -1,5 +1,5 @@ id: semantics/unwrap-sum-without-collapses -title: sum without over an unwrap range function returns a single series (open) +title: sum without over an unwrap range function keeps a series per remaining stream label set, like Loki (fixed) proves: - metric-series-identity - loki_api_v1_query_range @@ -8,11 +8,53 @@ consumer: explore why: | `sum without (pod) (max_over_time({app="payment-service"} | logfmt | unwrap amount [5m]))` keeps every label but pod on Loki 3.7.7: 17823 series on query_range and - 1596 on an instant query over an hour of generator data.

The error it hits then was recognised as the raw-row budget by the budget being equal to the limit that tripped, so an operator who set both limits to one value, or a check against the tenant's own limit at that value, got the other text. The request records whether the budget is the bound it reads under (it is, unless the tenant's limit is lower), the error follows that, and the tenant's own limit check clears the fold from its context. The error answers 400, a rejection of the query, where the raw-row reads answer 502: the limit reference and the operations notes say both. --- .../registry/generated/proxy/limits.json | 4 +- docs/api-reference.md | 2 +- docs/operations.md | 2 +- docs/reference/errors-and-alerts.md | 2 +- docs/reference/limits-registry.md | 2 +- internal/config/limits.go | 4 +- internal/proxy/manual_metric_budget.go | 17 +++- internal/proxy/range_metric_compat.go | 9 ++- .../proxy/sum_without_differential_test.go | 78 +++++++++++++++++++ internal/proxy/vector_matching.go | 11 ++- 10 files changed, 111 insertions(+), 20 deletions(-) diff --git a/conformance/registry/generated/proxy/limits.json b/conformance/registry/generated/proxy/limits.json index 644b05af5..e5dca034d 100644 --- a/conformance/registry/generated/proxy/limits.json +++ b/conformance/registry/generated/proxy/limits.json @@ -121,8 +121,8 @@ "default": "1000000", "unit": "rows", "bounds": "rows one proxy-side range-metric evaluation reads: raw log rows, or stats rows (one per non-empty step bucket and series) per bucket grid on the window stats path", - "error": "502 `manual range metric row limit exceeded (N); narrow the query or increase -manual-range-metric-row-limit`", - "metric": "loki_vl_proxy_requests_total{status=\"502\"}", + "error": "502 `manual range metric row limit exceeded (N); narrow the query or increase -manual-range-metric-row-limit`; the same text answers 400 when a `without` aggregation, which reads a series per stream before it folds them, holds more series than this limit and the limit is not below -max-stats-query-series (below it, the series limit is the bound and Loki's series message answers)", + "metric": "loki_vl_proxy_requests_total{status=\"502\"} (400 for a `without` aggregation)", "alert": "LokiVLProxyHighErrorRate (any sustained 5xx)", "loki_parity": "", "per_tenant": false, diff --git a/docs/api-reference.md b/docs/api-reference.md index e0c92cf84..e5d63e47b 100644 --- a/docs/api-reference.md +++ b/docs/api-reference.md @@ -150,7 +150,7 @@ All error responses from the proxy use the standard Loki JSON error envelope: | 406 / 422 | `not_acceptable` / `execution` | Loki status mapping (for example a backend returning that status) | | 499 | `canceled` | client canceled the request | | 500 | `internal` | proxy evaluation errors, including implicit many-to-one / multiple-match vector joins; a multi-tenant request where a tenant's backend request failed | -| 400 | `bad_data` | invalid LogQL, out-of-range parameters, `maximum number of series (N) reached for a single query` (as Loki answers above `max_query_series`) | +| 400 | `bad_data` | invalid LogQL, out-of-range parameters, `maximum number of series (N) reached for a single query` (as Loki answers above `max_query_series`), `manual range metric row limit exceeded` for a `without` aggregation whose series before the fold pass `-manual-range-metric-row-limit` | | 502 | `unavailable` | backend request failures, `manual range metric row limit exceeded` | | 503 | `timeout` | circuit breaker open | | 504 | `timeout` | backend or window timeouts, including a timeout on one tenant of a multi-tenant request | diff --git a/docs/operations.md b/docs/operations.md index e4ef272de..48e97ef67 100644 --- a/docs/operations.md +++ b/docs/operations.md @@ -383,7 +383,7 @@ For exact proxy-only overhead on translated paths, use structured request logs w Not every `502` or `503` means VictoriaLogs is down.

The differential test sends the other shapes (sum, avg, count, max, min and topk of per-series functions, rate and count_over_time, a without under another aggregation) through the handler on an emulated VictoriaLogs, as an instant query, a tumbling window and a sliding one, and pins the LogsQL sent and the answer to the ones origin/main produced. A second test pins the proxy's answers beside a reference evaluator that follows the Loki sources, and two open rows register the series identity outside without and a parsed key that is also a stream label (Loki names it key_extracted). The figures come from the emulator, not from a Loki run. --- ...nwrap-extraction-list-series-identity.yaml | 72 +++ ...y-per-series-function-extraction-list.yaml | 12 +- .../unwrap-sum-without-collapses.yaml | 11 +- ...sum-without-extracted-label-collision.yaml | 50 +++ conformance/registry/generated/wiring.json | 22 +- conformance/reports/gaps.md | 2 +- conformance/reports/parity-gaps.md | 118 ++--- conformance/reports/roadmap.md | 2 +- .../extraction_list_outside_without_test.go | 414 ++++++++++++++++++ .../proxy/sum_without_label_collision_test.go | 47 ++ 10 files changed, 679 insertions(+), 71 deletions(-) create mode 100644 conformance/registry/cases/semantics/unwrap-extraction-list-series-identity.yaml create mode 100644 conformance/registry/cases/semantics/unwrap-sum-without-extracted-label-collision.yaml create mode 100644 internal/proxy/extraction_list_outside_without_test.go create mode 100644 internal/proxy/sum_without_label_collision_test.go diff --git a/conformance/registry/cases/semantics/unwrap-extraction-list-series-identity.yaml b/conformance/registry/cases/semantics/unwrap-extraction-list-series-identity.yaml new file mode 100644 index 000000000..a72b6f41e --- /dev/null +++ b/conformance/registry/cases/semantics/unwrap-extraction-list-series-identity.yaml @@ -0,0 +1,72 @@ +id: semantics/unwrap-extraction-list-series-identity +title: outside a without, an aggregation over a range function after an extraction list reads other series than Loki's (open) +proves: + - metric-series-identity + - loki_api_v1_query_range + - loki_api_v1_query +consumer: explore +why: | + After a parser that names the keys it extracts (`| logfmt amount`, + `| logfmt amount, route`), a Loki series is the stream plus those labels, less + the unwrapped one (pkg/logql/log/metrics_extraction.go:150-178), and the vector + aggregation folds the per-series values of the range function + (pkg/logql/evaluator.go:435-529 VectorAggEvaluator.Next).
