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 - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment.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

Arthur Silva Sens	07355c9199	Bump client_golang to 1.19 Signed-off-by: Arthur Silva Sens <arthur.sens@coralogix.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.

Łukasz Mierzwa	5597020a60	Use github.com/klauspost/compress for gzip and zlib klauspost/compress is a high quality drop-in replacement for common Go compression libraries. Since Prometheus sends out a lot of HTTP requests that often return compressed output having improved compression libraries helps to save cpu & memory resources.

zenador	32ee1b15de	Fix error on ingesting out-of-order exemplars (#13021 ) Fix and improve ingesting exemplars for native histograms. See code comment for a detailed explanation of the algorithm. Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed. Also note that we now do not ingest exemplars without timestamps for native histograms anymore.

beorn7	65ccf4460a	textparse: Fix endless loop #12731 PR #12557 introduced the possibility of parsing multiple exemplars per native histograms. It did so by requiring the `Exemplar` method of the parser to be called repeatedly until it returns false. However, the protobuf parser code wasn't correctly updated for the old case of a single exemplar for a classic bucket (if actually parsed as a classic bucket) and a single exemplar on a counter. In those cases, the method would return `true` forever, yielding the same exemplar again and again, leading to an endless loop. With this fix, the state is now tracked and the single exemplar is only returned once. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

beorn7	c58e20ad0e	histogram: Identify native histograms even without observations Native histograms without observations and with a zero threshold of zero look the same as classic histograms in the protobuf exposition format. According to https://github.com/prometheus/client_golang/issues/1127 , the idea is to add a no-op span to those histograms to mark them as native histograms. This commit enables Prometheus to detect that no-op span and adds a doc comment to the proto spec describing the behavior. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
