beorn7	e9d9bb1b08	textparse: Handle unknown metric types in protobuf gracefully So far, the parser hasn't validated that the type is valid in the `Next()` call. Later, in the `Series()` call, however, it assumes that we will only see valid types and therefore panics with `encountered unexpected metric type, this is a bug`. This commit fixes said bug by adding validation to the `Next()` call. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
Damien Grisonnet	96b9d8cebb	model/textparse: associate correct token to errors In some cases, the Prometheus HTTP format parser was not returning the right token in the error output which made debugging impossible. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>	2 years ago

Bryan Boreham	8120af22e2	benchmarks: SetBytes takes bytes per operation Where the code was multiplying bytes by number of operations, this resulted in absurdly high throughput numbers. Also, in `BenchmarkParse()`, don't run the `expfmt` case twice. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
beorn7	a7c519930e	histograms: Add Compact method to the normal integer Histogram And use the new method to call to compact Histograms during parsing. This happens for both `Histogram` and `FloatHistogram`. In this way, if targets decide to optimize the exposition size by merging spans with empty buckets in between, we still get a normalized results. It will also normalize away any valid but weird representations like empty spans, spans with offset zero, and empty buckets at the start or end of a span. The implementation seemed easy at first as it just turns the `compactBuckets` helper into a generic function (which now got its own file). However, the integer Histograms have delta buckets instead of absolute buckets, which had to be treated specially in the generic `compactBuckets` function. To make sure it works, I have added plenty of explicit tests for `Histogram` in addition to the `FloatHistogram` tests. I have also updated the doc comment for the `Compact` method. Based on the insights now expressed in the doc comment, compacting with a maxEmptyBuckets > 0 is rarely useful. Therefore, this commit also sets the value to 0 in the two cases we were using 3 so far. We might still want to reconsider, so I don't want to remove the maxEmptyBuckets parameter right now.
