Bryan Boreham	786e0e706c	test: PromQL: stop using internal fields of engine * set enablePerStepStats and lookback duration via `NewTestEngine` parameters. * check maxSamples by recreating query engine * check lookback without modifying internals Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	7 months ago
Bryan Boreham	0dbfd20b69	test: move most PromQL tests into separate test package So that they can import promqltest which imports promql. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	7 months ago

Bryan Boreham	babfcfdd91	refactor: Move NewTestEngine into promqltest And export `DefaultMaxSamplesPerQuery` so callers can replicate previous behaviour. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	7 months ago
Oleg Zaytsev	dabd789fd5	Quote label name in matchers when needed When the label name of a matcher contains non-standard characters, like a dot, or starts with a digit, it should be quoted. If it's not quoted, then `VectorSelector.String()` isn't a valid PromQL. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	7 months ago

Bryan Boreham	a1af3c27d4	refactor: extract almost.Equal() to new package To avoid a circular reference between promql and promqltest. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	7 months ago
Arve Knudsen	a25160e6a4	[REFACTOR] PromQL: simplify rangeEvalTimestampFunctionOverVectorSelector (#14021 ) The function `rangeEvalTimestampFunctionOverVectorSelector` appeared to be checking histogram size, however the value it used was always 0 due to subtle variable shadowing. However we don't need to pass sample values to the `timestamp` function, since the latter only cares about timestamps. This also affects peak sample count in statistics, since we are no longer copying histogram samples. Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com>	7 months ago
Oleg Zaytsev	4b7a44c7a0	Fix `parser.VectorSelector.String()` with empty name matcher (#14015 ) The check fell into "this matcher equals vector selector's name" case when vector selector doesn't have a name and the matcher is an explicit matcher for an empty __name__ label. To provide some context about why this is important: some downstream projects use the promql.Parse(expr.String()) to clone an expression's AST, and with this bug that matcher disappears in the cloning.

guangwu	9fda9443d4	fix(promql/query_logger): close file in error handling (#13948 ) Signed-off-by: guoguangwu <guoguangwug@gmail.com>	7 months ago
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.

Bryan Boreham	cfbeb6681b	promql: re-use one heap for topk and bottomk Slightly ugly casting saves memory. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
Bryan Boreham	5e3914a27c	promql: remove histogramMean from groupedAggregation Re-use histogramValue since we don't need them separately. Tidy up initialization. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
Bryan Boreham	2cf3c9de8f	promql: store labels per-group only for count_values This saves memory in other kinds of aggregation. We don't need `orderedResult` in `aggregationCountValues`; the ordering is not guaranteed. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	526ce4ee7a	promql: simplify data collection in aggregations We don't need a Sample, just the float and histogram values. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
Bryan Boreham	2f03acbafc	promql: refactor: split topk/bottomk from sum/avg/etc They aggregate results in different ways. topk/bottomk don't consider histograms so can simplify data collection. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
Bryan Boreham	74eed67ef6	promql: refactor: pull fetching input data out of rangeEvalAgg This is a cleaner split of responsibilities. We now check the sample count after calling rangeEvalAgg. Changed re-use of samples to use `Clone` and `defer`. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	cb6c4b3092	promql: simplify k/q parameter to topk/bottomk/quantile Pass it as a float64 not as interface{}. Make k a simple int, since that is the parameter to make(). Pull invalid quantile warning out of the loop. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	59548b8a0b	promql: refactor: move collection of results into aggregation() We don't need to check for duplicates as aggregation cannot generate them. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
