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

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>	1 year ago

beorn7	c58e20ad0e	histogram: Identify native histograms even without observations Native histograms without observations and with a zero threshold of zero look the same as classic histograms in the protobuf exposition format. According to https://github.com/prometheus/client_golang/issues/1127 , the idea is to add a no-op span to those histograms to mark them as native histograms. This commit enables Prometheus to detect that no-op span and adds a doc comment to the proto spec describing the behavior. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

beorn7	9aadd54786	histogram: Fix bounds of buckets returned by floatBucketIterator The bounds weren't really used so far, so no actual bug in the code so far. But it's obviously confusing if the bounds returned by a floatBucketIterator with a target schema different from the original schema are wrong. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
beorn7	071f4bbea4	histograms: Fix parsing float histograms without zero bucket If a float histogram has a zero bucket with a threshold of zero _and_ an empty zero bucket, it wasn't identified as a native histogram because the `isNativeHistogram` helper function only looked at integer buckets. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
beorn7	2ea8df4734	histogram: Expose #12305 Native histograms without a zero threshold aren't federated properly. This adds a test to prove the specific failure mode, which is that histograms with a zero threshold of zero are federated as classic histograms. The underlying reason is that the protobuf parser identifies a native histogram by detecting a zero bucket or by detecting integer buckets. Therefore, a float histogram with a zero threshold of zero and an unpopulated zero bucket falls through the cracks (no integer buckets, no zero bucket). This commit also addse a test case for the latter. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

beorn7	0e3f35324b	scrape: Enable ingestion of multiple exemplars per sample This has become a requirement for native histograms, as a single histogram sample commonly has many buckets, so that providing many exemplars makes sense. Since OM text doesn't support native histograms yet, the test had to be expanded to also support protobuf test cases. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
beorn7	da047c6857	histograms: Fix bug #12552 The problem was the following: When trying to parse native histograms and classic histograms in parallel, the parser would first parse the histogram proto messages as a native histogram and then parse the same message again, but now as a classic histogram. Afterwards, it would forget that it was dealing with a metric family that contains native histograms and would parse the rest of the metric family as classic histograms only. The fix is to check again after being done with a classic histogram. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
