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 - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment.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 `//`.

Jan Fajerski	7c8c748399	promql tests: adjust range query intervals ... Some test queries need their interval adjusted to account for https://github.com/prometheus/prometheus/pull/13904. Otherwise the queries don't return enough samples. promql/engine_test.go:TestHistogramCopyFromIteratorRegression needed the same, but also the result needed a fix since `increase` interpolates over the full range.

Filip Petkovski	be7a4c9b83	Ignore stale histograms for counter reset detection ... The histogram stats decoder keeps track of the last seen histogram sample in order to properly detect counter resets. We are seeing an issue where a histogram with UnknownResetHint gets treated as a counter reset when it follows a stale histogram sample. I believe that this is incorrect since stale samples should be completely ignored in PromQL. As a result, they should not be stored in the histogram stats iterator and the counter reset detection needs to be done against the last non-stale sample.

beorn7	cff0429b1a	promql: make avg_over_time faster and more precise ...

beorn7	3a908d8e08	promql: Improve Kahan usage in avg_over_time ... The calculation of the mean value in avg_over_time is performed in an incremental fashion.

beorn7	c46074f4dd	promql: make avg aggregation more precise and less expensive ... The basic idea here is that the previous code was always doing incremental calculation of the mean value, which is more costly and can be less precise. It protects against overflows, but in most cases, an overflow doesn't happen anyway. The other idea applied here is to expand on #14074, where Kahan summation was applied to sum(). With this commit, the average is calculated in a conventional way (adding everything up and divide in the end) as long as the sum isn't overflowing float64. This is combined with Kahan summation so that the avg aggregation, in most cases, is really equivalent to the sum aggregation with a following division (which is the user's expectation as avg is supposed to be syntactic sugar for sum with a following divison). If the sum hits ±Inf, the calculation reverts to incremental calculation of the mean value. Kahan summation is also applied here, although it cannot fully compensate for the numerical errors introduced by the incremental mean calculation. (The tests added in this commit would fail if incremental mean calculation was always used.) Signed-off-by: beorn7 <beorn@grafana.com>	2024-07-10 19:20:24 +02:00

Filip Petkovski	acb6c1ae4b	Fix decoding buckets for native histograms in binops ...

This should help with reducing allocations when decoding histograms, as well as with speeding up aggregations like sum since they will be done on floats and not on histogram objects.
