Bryan Boreham	5571c7dc98	FastRegexMatcher: use stack memory for lowercase copy of string Up to 32-byte values this saves garbage, runs faster. For prefixes, only `toLower` the part we need for the map lookup. Split toNormalisedLower into fast and slow paths, to avoid a penalty for the `copy` call in the case where no allocations are done.

György Krajcsovits	eafe72a0d0	perf(nhcb): optimize away most allocations in convertnhcb In general aim for the happy case when the exposer lists the buckets in ascending order. Use Compact(2) to compact the result of nhcb convert. This is more in line with how client_golang optimizes spans vs buckets. `aef8aedb4b/prometheus/histogram.go (L1485)` Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	4 weeks ago
George Krajcsovits	eb3b349024	fix(nhcb): created timestamp fails when keeping classic histograms (#15218 ) The wrong source was used to return the created timestamp, leading to index out of bound panic. One line fix. Refactor the requirement test to be generic and be able to test OpenMetrics and Prom parsers as well. There are some differencies in what the parsers support, the Prom parser doesn't have created timestamp. The protobuf parser uses different formatting to identify the metric for the scrape loop. Each parser represents the sample timestamp differently. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	4 weeks ago
George Krajcsovits	469573b13b	fix(nhcb): do not return nhcb from parse if exponential is present (#15209 ) From: https://github.com/prometheus/prometheus/pull/14978#discussion_r1800755481 Also encode the requirement table set in #13532 Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	1 month ago
George Krajcsovits	2182b83271	feat(nhcb): implement created timestamp handling (#15198 ) Call through to the underlaying parser if we are not in a histogram and the entry is a series or exponential native histogram. Otherwise store and retrieve CT for NHCB. * fix(omparser): losing exemplars when CT is parsed Fixes: #15137 Ignore exemplars while peeking ahead during CT parsing. Simplify state reset with defer().
