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.

Making changes to textparse lexers

In the rare case that you need to update the textparse lexers, edit promlex.l or openmetricslex.l and then run the following command: golex -o=promlex.l.go promlex.l

Note that you need golex installed: go get -u modernc.org/golex
