beorn7	9e500345f3	textparse/scrape: Add option to scrape both classic and native histograms So far, if a target exposes a histogram with both classic and native buckets, a native-histogram enabled Prometheus would ignore the classic buckets. With the new scrape config option `scrape_classic_histograms` set, both buckets will be ingested, creating all the series of a classic histogram in parallel to the native histogram series. For example, a histogram `foo` would create a native histogram series `foo` and classic series called `foo_sum`, `foo_count`, and `foo_bucket`. This feature can be used in a migration strategy from classic to native histograms, where it is desired to have a transition period during which both native and classic histograms are present. Note that two bugs in classic histogram parsing were found and fixed as a byproduct of testing the new feature: 1. Series created from classic _gauge_ histograms didn't get the _sum/_count/_bucket prefix set. 2. Values of classic _float_ histograms weren't parsed properly.

Julien Pivotto	58c445e6ef	Fuzz: limit input size (#7317 ) We know that fuzzParseExpr and fuzzParseMetricSelector make use of heavy things like regexes, which take a fairly big amount of memory. OSS-Fuzz does not offer a proper way to increase the memory [1], therefore we limit the input size [2].
