Filip Petkovski	10a82f87fd	Enable reusing memory when converting between histogram types ... The 'ToFloat' method on integer histograms currently allocates new memory each time it is called. This commit adds an optional *FloatHistogram parameter that can be used to reuse span and bucket slices. It is up to the caller to make sure the input float histogram is not used anymore after the call. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	2 years ago

Bryan Boreham	a3e02f35d6	labels: extract common code between slice and stringlabels ... This reduces bulk and should avoid issues if a fix is made in one file and not the other. A few methods now call `Range()` instead of `range`, but nothing performance-sensitive. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
zenador	32ee1b15de	Fix error on ingesting out-of-order exemplars (#13021) ... Fix and improve ingesting exemplars for native histograms. See code comment for a detailed explanation of the algorithm. Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed. Also note that we now do not ingest exemplars without timestamps for native histograms anymore.

Ziqi Zhao	ab2a7bb74f	add generic shrink function (#13001) ... Add `ReduceResolution` method to `Histogram` and `FloatHistogram` This takes the original `mergeToSchema` function and turns it into a more generic `reduceResolution` function, which is the building block for the new methods.

beorn7	65ccf4460a	textparse: Fix endless loop #12731 ... PR #12557 introduced the possibility of parsing multiple exemplars per native histograms. It did so by requiring the `Exemplar` method of the parser to be called repeatedly until it returns false. However, the protobuf parser code wasn't correctly updated for the old case of a single exemplar for a classic bucket (if actually parsed as a classic bucket) and a single exemplar on a counter. In those cases, the method would return `true` forever, yielding the same exemplar again and again, leading to an endless loop. With this fix, the state is now tracked and the single exemplar is only returned once. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
