George Krajcsovits acd9aa0afb fix(textparse/protobuf): metric family name corrupted by NHCB parser (#17156 ) * fix(textparse): implement NHCB parsing in ProtoBuf parser directly The NHCB conversion does some validation, but we can only return error from Parser.Next() not Parser.Histogram(). So the conversion needs to happen in Next(). There are 2 cases: 1. "always_scrape_classic_histograms" is enabled, in which case we convert after returning the classic series. This is to be consistent with the PromParser text parser, which collects NHCB while spitting out classic series; then returns the NHCB. 2. "always_scrape_classic_histograms" is disabled. In which case we never return the classic series. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * refactor(textparse): skip classic series instead of adding NHCB around Do not return the first classic series from the EntryType state, switch to EntrySeries. This means we need to start the histogram field state from -3 , not -2. In EntrySeries, skip classic series if needed. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * reuse nhcb converter Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * test(textparse/nhcb): test corrupting metric family name NHCB parse doesn't always copy the metric name from the underlying parser. When called via HELP, UNIT, the string is directly referenced which means that the read-ahead of NHCB can corrupt it. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>		4 months ago

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
