beorn7	c7fdfe8004	promql: Add tests for histogram counter reset only in bucket This also exercises the "fast path" (only decoding count and sum), i.e. where the counter reset isn't visible at all in the decoded data. Signed-off-by: beorn7 <beorn@grafana.com>	6 months ago
Filip Petkovski	6e68046c25	Implement histogram statistics decoder (#14097 ) Implement histogram statistics decoder This commit speeds up histogram_count and histogram_sum functions on native histograms. The idea is to have separate decoders which can be used by the engine to only read count/sum values from histogram objects. This should help with reducing allocations when decoding histograms, as well as with speeding up aggregations like sum since they will be done on floats and not on histogram objects.

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.

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.

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.
