Owen Williams	4a6f8704ef	parser: remake generated_parser output (#13923 ) In a previous PR, the generated parser was created using an old version of goyacc. Also adds -l to disable line directives, which fixes debug processing and reduces diffs at the expense of making it more difficult to reason about the generated output.

Owen Williams	a28d7865ad	UTF-8: Add support for parsing UTF8 metric and label names This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats. This grammar will also be valid for non-UTF-8 names. UTF-8 names will not be considered valid unless model.NameValidationScheme is changed. This does not update the go expfmt parser in text_parse.go, which will be addressed by https://github.com/prometheus/common/issues/554/.

Julien Pivotto	c92fbf3fdf	Add feature flag for PromQL experimental functions. This PR adds an Experimental flag to the functions. This can be used by https://github.com/prometheus/prometheus/pull/13059 but also xrate and other future functions. Signed-off-by: Julien Pivotto <roidelapluie@o11y.eu>	1 year ago
zenador	69edd8709b	Add warnings (and annotations) to PromQL query results (#12152 ) Return annotations (warnings and infos) from PromQL queries This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations". Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future. The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms). The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later. Another TODO is to take annotations into account when evaluating recording rules. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	1 year ago
Gregor Zeitlinger	f01718262a	Unit tests for native histograms (#12668 ) promql: Extend testing framework to support native histograms This includes both the internal testing framework as well as the rules unit test feature of promtool. This also adds a bunch of basic tests. Many of the code level tests can now be converted to tests within the framework, and more tests can be added easily. --------- Signed-off-by: Harold Dost <h.dost@criteo.com> Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com> Signed-off-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Harold Dost <h.dost@criteo.com> Co-authored-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>	1 year ago

Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Filip Petkovski	97c7fffbb8	parser: Allow parsing arbitrary functions In Thanos we would like to start experimenting with custom functions that are currently not part of the PromQL spec. We would do this by adding an implementation for those functions in the Thanos engine: https://github.com/thanos-community/promql-engine and allow users to decide which engine they want to use on a per-query basis. Since we use the PromQL parser from Prometheus, injecting functions in the global `Functions` variable would mean they also become available for the Prometheus engine. To avoid this side-effect, this commit exposes a Parser interface in which the supported functions can be injected as an option. If not functions are injected, the parser implementation will default to the functions defined in the global Functions variable. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	2 years ago
Bryan Boreham	56fefcd812	Update package promql for new labels.Labels type We use `labels.Builder` to parse metrics, to avoid depending on the internal implementation. This is not efficient, but the feature is only used in tests. It wasn't efficient previously either - calling `Sort()` after adding each label. `createLabelsForAbsentFunction` also uses a Builder now, and gets an extra `map` to replace the previous `Has()` usage.

Julien Pivotto	cab96a06ef	Merge release 2.29 in main (#9196 ) * PromQL: Fix start and end keywords masking label and metric names This commit fixes an issue with the "at modifier" that introduced two new keywords: `start` and `end`. In grouping options and in metric names, these keywords took precedence over metric or label names, so that those metrics and labels could no longer be referenced.
