beorn7	0f760f63dd	lint: Revamp our linting rules, mostly around doc comments Several things done here: - Set `max-issues-per-linter` to 0 so that we actually see all linter warnings and not just 50 per linter. (As we also set `max-same-issues` to 0, I assume this was the intention from the beginning.) - Stop using the golangci-lint default excludes (by setting `exclude-use-default: false`. Those are too generous and don't match our style conventions. (I have re-added some of the excludes explicitly in this commit. See below.) - Re-add the `errcheck` exclusion we have used so far via the defaults. - Exclude the signature requirement `govet` has for `Seek` methods because we use non-standard `Seek` methods a lot. (But we keep other requirements, while the default excludes completely disabled the check for common method segnatures.) - Exclude warnings about missing doc comments on exported symbols. (We used to be pretty adamant about doc comments, but stopped that at some point in the past. By now, we have about 500 missing doc comments. We may consider reintroducing this check, but that's outside of the scope of this commit. The default excludes of golangci-lint essentially ignore doc comments completely.) - By stop using the default excludes, we now get warnings back on malformed doc comments. That's the most impactful change in this commit. It does not enforce doc comments (again), but _if_ there is a doc comment, it has to have the recommended form. (Most of the changes in this commit are fixing this form.) - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment. - Leave `package-comments` inactive, but add a TODO asking if we should change that. - Add a new sub-linter `comment-spacings` (and fix corresponding comments), which avoids missing spaces after the leading `//`.

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>	8 months ago
Bryan Boreham	0bb5588386	labels: optimize String method (#13673 ) Use a stack buffer to reduce memory allocations. `Write(AppendQuote(AvailableBuffer` does not allocate or copy when the buffer has sufficient space. Also add a benchmark, with some refactoring. Signed-off-by: Bryan Boreham <bjboreham@gmail.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.
