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 - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment.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

Bryan Boreham	9a74d53935	[BUGFIX] TSDB: Fix query overlapping in-order and ooo head (#14693) ... * tsdb: Unit test query overlapping in order and ooo head Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * TSDB: Merge overlapping head chunk The basic idea is that getOOOSeriesChunks can populate Meta.Chunk, but since it only returns one Meta per overlapping time-slot, that pointer may end up in a Meta with a head-chunk ID. So we need HeadAndOOOChunkReader.ChunkOrIterable() to call mergedChunks in that case. Previously, mergedChunks was checking that meta.Ref was a valid OOO chunk reference, but it never actually uses that reference; it just finds all chunks overlapping in time. So we can delete that code. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> Co-authored-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	2024-08-21 14:24:20 +01:00

Bryan Boreham	d1ea6eb35d	Merge pull request #14354 from bboreham/ooo-head-together ... [PERF] TSDB: Query head and ooo-head together The current implementation of out-of-order querying runs two queriers which each iterate all series in the head, then runs a merge operation on the output. This PR adds HeadAndOOOQuerier which iterates just once over series, then where necessary merges chunks from in-order and out-of-order lists. In order to distinguish in-order from out-of-order chunk references I set bit 23 (i.e. 1<<23) on ooo references; this reduces the maximum number of chunks from 16 million to 8 million. Note one side-effect of this change is that results may come in a different order - the merge operation done previously required a sort of all series. This only changes where Prometheus does not guarantee the order. Fixes #11628	2024-08-14 14:39:30 +01:00
