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 - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment.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>	3 months ago

George Krajcsovits	00ab05c3b9	Native histograms: fix spurios counter reset when merging recoded chunk to normal chunk (#14513 ) * chunkenc: allow missing empty buckets on histogram append Allow appending to chunks when the histogram to be added is missing some buckets, but the missing buckets are empty in the chunk. For example bucket at index 5 is present in the chunk, but its value is 0 and the new histogram doesn't have a bucket at index 5. This fixes an issue of merging chunks where one chunk was recoded to retroactively have some empty buckets in all the histograms and we are merging in a histogram that doesn't have the empty bucket (because it was not recoded yet). The operation alters the histogram that is being added, however this has already been the case when appending gauge histograms. Thus the test TestHistogramSeriesToChunks in storage package is changed to explicitly test what happened to the appended histogram - Compact(0) call is removed. The new expandIntSpansAndBuckets and expandFloatSpansAndBuckets functions are a merge of expandSpansForward and counterResetInAnyBucket and counterResetInAnyFloatBucket.

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.
