Oleg Zaytsev	9699598952	Improve Labels.Compare performance w/stringlabels I was bored on a train and I spent some amount of time trying to scratch some nanoseconds off the Labels.Compare when running with stringlabels. I would be ashamed to admit the real amount of time I spent on it. The worst thing is, I can't really explain why this is performing so much better, and someone should re-run the benchmarks on their machine to confirm that it's not something related to general relativity because the train is moving. I also added some extra real-life benchmark cases with longer labelsets (these aren't the longest we have in production, but kubernetes labelsets are fairly common in Prometheus so I thought it would be nice to have them). My benchmarks show this diff: goos: darwin goarch: arm64 pkg: github.com/prometheus/prometheus/model/labels │ old │ new │ │ sec/op │ sec/op vs base │ Labels_Compare/equal 5.898n ± 0% 5.875n ± 1% -0.40% (p=0.037 n=10) Labels_Compare/not_equal 11.78n ± 2% 11.01n ± 1% -6.54% (p=0.000 n=10) Labels_Compare/different_sizes 4.959n ± 1% 4.906n ± 2% -1.05% (p=0.050 n=10) Labels_Compare/lots 21.32n ± 0% 17.54n ± 5% -17.75% (p=0.000 n=10) Labels_Compare/real_long_equal 15.06n ± 1% 14.92n ± 0% -0.93% (p=0.000 n=10) Labels_Compare/real_long_different_end 25.20n ± 0% 24.43n ± 0% -3.04% (p=0.000 n=10) geomean 11.86n 11.25n -5.16% Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	9 months ago

Ondrej Kokes	2e30f1231b	docs: textparse.Parser return type mismatch The docs suggest the Next method returns a bool, but that's not the case (`Entry` is an int). ``` // Next advances the parser to the next sample. It returns false if no // more samples were read or an error occurred. Next() (Entry, error) ``` The docs were first added in `d80a3de235` in 2017. Back then the signature was indeed `func (p *Parser) Next() bool`. But then it got refactored in `76a4a46cb0` and the signature changed with it, yet docs stayed the same - and eventually made their way into the `Parser` interface. However, the Protobuf parser does have the right wording: `5de2df752f` ``` // Next advances the parser to the next "sample" (emulating the behavior of a // text format parser). It returns (EntryInvalid, io.EOF) if no samples were // read. ``` Changing all other implementations (and the interface itself) to match this doc.

Bryan Boreham	d51a5344cd	labels: new version de-duplicating strings in SymbolTables The individual strings for label names and values are held in a table, and each Labels value is a run of varint-encoded indexes into that table.
