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.

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

beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

György Krajcsovits	6c646657d5	perf(chunkenc): intern the custom values for native histograms The custom values are the "le" bucket boundaries of native histograms with custom buckets.

Bryan Boreham	b2c2146d7c	Labels: simpler/faster stringlabels encoding (#16069 ) Instead of using varint to encode the size of each label, use a single byte for size 0-254, or a flag value of 255 followed by the size in 3 bytes little-endian. This reduces the amount of code, and also the number of branches in commonly-executed code, so it runs faster. The maximum allowed label name or value length is now 2^24 or 16MB. Memory used by labels changes as follows: * Labels from 0 to 127 bytes length: same * From 128 to 254: 1 byte less * From 255 to 16383: 2 bytes more * From 16384 to 2MB: 1 byte more * From 2MB to 16MB: same Labels: panic on string too long. Slightly more user-friendly than encoding bad data and finding out when we decode.

frazou	9b4c8f6be2	rulefmt: support YAML aliases for Alert/Record/Expr (#14957 ) * rulefmt: add tests with YAML aliases for Alert/Record/Expr Altough somewhat discouraged in favour of using proper configuration management tools to generate full YAML, it can still be useful in some situations to use YAML anchors/aliases in rules. The current implementation is however confusing: aliases will work everywhere except on the alert/record name and expr This first commit adds (failing) tests to illustrate the issue, the next one fixes it. The YAML test file is intentionally filled with anchors and aliases. Although this is probably not representative of a real-world use case (which would have less of them), it errs on the safer side. Signed-off-by: François HORTA <fhorta@scaleway.com> * rulefmt: support YAML aliases for Alert/Record/Expr This fixes the use of YAML aliases in alert/recording rule names and expressions. A side effect of this change is that the RuleNode YAML type is no longer propagated deeper in the codebase, instead the generic Rule type can now be used.
