Ben Kochie	48956f60d7	Update modernize (#17471 ) Apply additional Go modernize tool improvements. Signed-off-by: SuperQ <superq@gmail.com>	1 month ago
beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

Bryan Boreham	d186caead5	Merge pull request #14496 from bboreham/fix-nil-primary (#14509 ) [BUGFIX] Storage: errors from a single secondary querier should be warnings. This is a backport of #14496 to release-2.54 branch. #13434 introduced an unwanted change in behaviour: if there was no primary querier and a single secondary querier, the secondary would be treated like a primary. This PR restores the previous behaviour, that all secondary queriers report errors as warnings. In order to test this behaviour, I changed `TestMergeQuerierWithSecondaries_ErrorHandling` so it now calls `NewMergeQuerier` rather than creating the internal data structure directly. This in turn required all the data types to change, so I merged `mockGenericQuerier` into `mockQuerier`. Also replaced `unwrapMockGenericQuerier` with a visitor pattern. While I was there, I addressed the comment from https://github.com/prometheus/prometheus/pull/13434#pullrequestreview-2191058921 to short-circuit the merge of single querier with any number of no-op or nil queriers.

Bryan Boreham	fbca054af6	storage: don't wrap single querier in merge-queriers If given a single querier, just return it instead of constructing a complicated wrapper. The code in `mergeGenericQuerier` which skipped merging when there was only one is not needed any more. This change required a few tests to be tweaked, because they relied on the specific behaviour of `mergeGenericQuerier.Select()`. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
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>	2 years 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>	2 years ago

Justin Lei	8ef7dfdeeb	Add a chunk size limit in bytes (#12054 ) Add a chunk size limit in bytes This creates a hard cap for XOR chunks of 1024 bytes. The limit for histogram chunk is also 1024 bytes, but it is a soft limit as a histogram has a dynamic size, and even a single one could be larger than 1024 bytes. This also avoids cutting new histogram chunks if the existing chunk has fewer than 10 histograms yet. In that way, we are accepting "jumbo chunks" in order to have at least 10 histograms in a chunk, allowing compression to kick in. Signed-off-by: Justin Lei <justin.lei@grafana.com>	2 years ago
beorn7	630bcb494b	storage: Use separate sample types for histogram vs. float Previously, we had one “polymorphous” `sample` type in the `storage` package. This commit breaks it up into `fSample`, `hSample`, and `fhSample`, each still implementing the `tsdbutil.Sample` interface. This reduces allocations in `sampleRing.Add` but inflicts the penalty of the interface wrapper, which makes things worse in total. This commit therefore just demonstrates the step taken. The next commit will tackle the interface overhead problem. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Björn Rabenstein	7e42acd3b1	tsdb: Rework iterators (#9877 ) - Pick At... method via return value of Next/Seek. - Do not clobber returned buckets. - Add partial FloatHistogram suppert. Note that the promql package is now _only_ dealing with FloatHistograms, following the idea that PromQL only knows float values. As a byproduct, I have removed the histogramSeries metric. In my understanding, series can have both float and histogram samples, so that metric doesn't make sense anymore. As another byproduct, I have converged the sampleBuf and the histogramSampleBuf in memSeries into one. The sample type stored in the sampleBuf has been extended to also contain histograms even before this commit. Signed-off-by: beorn7 <beorn@grafana.com>	4 years ago

Bartlomiej Plotka	28c5cfaf0d	tsdb: Moved code merge series and iterators to differen files; cleanup. No functional changes just move! (#7714 ) I did not want to move those in previous PR to make it easier to review. Now small cleanup time for readability. (: ## Changes * Merge series goes to `storage/merge.go` leaving `fanout.go` for just fanout code. * Moved `fanout test` code from weird separate package to storage. * Unskiped one test: TestFanout_SelectSorted/chunk_querier * Moved block series set codes responsible for querying blocks to `querier.go` from `compact.go` Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago
