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 - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment.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

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. On a test Prometheus server I was able to see cpu reduction from 31 to 30 cores.

Filip Petkovski	583f3e587c	Optimize histogram iterators (#13340 ) Optimize histogram iterators Histogram iterators allocate new objects in the AtHistogram and AtFloatHistogram methods, which makes calculating rates over long ranges expensive. In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	10 months ago

Fiona Liao	5bee0cfce2	Change `ChunkReader.Chunk()` to `ChunkOrIterable()` The ChunkReader interface's Chunk() has been changed to ChunkOrIterable(). This is a precursor to OOO native histogram support - with OOO native histograms, the chunks.Meta passed to Chunk() can result in multiple chunks being returned rather than just a single chunk (e.g. if oooMergedChunk has a counter reset in the middle). To support this, ChunkOrIterable() requires either a single chunk or an iterable to be returned. If an iterable is returned, the caller has the responsibility of converting the samples from the iterable into possibly multiple chunks. The OOOHeadChunkReader now returns an iterable rather than a chunk to prepare for the native histograms case. Also as a beneficial side effect, oooMergedChunk and boundedChunk has been simplified as they only need to implement the Iterable interface now, not the full Chunk interface. --------- Signed-off-by: Fiona Liao <fiona.y.liao@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	1 year ago

zenador	69edd8709b	Add warnings (and annotations) to PromQL query results (#12152 ) Return annotations (warnings and infos) from PromQL queries This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations". Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future. The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms). The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later. Another TODO is to take annotations into account when evaluating recording rules. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	1 year ago
