beorn7	86d7618d84	promql: Fix wrongly scoped range vectors Fixes #11708. If a range vector is fixen in time with the @ modifier, it gets still moved around for different steps in a range query. Since no additional points are retrieved from the TSDB, this leads to steadily emptying the range, leading to the weird behavior described in isse #11708. This only happens for functions listed in `AtModifierUnsafeFunctions`, and the only of those that takes a range vector is `predict_linear`, which is the reason why we see it only for this particular function.

This sample is now coming from the buffered iterator used for windowing functions, and can be reused for reading subsequent samples as the iterator progresses.

Bryan Boreham	74b73d1e2c	Labels: Add DropMetricName function, used in PromQL (#13446 ) This function is called very frequently when executing PromQL functions, and we can do it much more efficiently inside Labels. In the common case that `__name__` comes first in the labels, we simply re-point to start at the next label, which is nearly free. `DropMetricName` is now so cheap I removed the cache - benchmarks show everything still goes faster.

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

Filip Petkovski	1f69dcfa6b	Fix reusing float histograms In https://github.com/prometheus/prometheus/pull/13276 we started reusing float histogram objects to reduce allocations in PromQL. That PR introduces a bug where histogram pointers gets copied to the beginning of the histograms slice, but are still kept in the end of the slice. When a new histogram is read into the last element, it can overwrite a previous element because the pointer is the same. This commit fixes the issue by moving outdated points to the end of the slice so that we don't end up with duplicate pointers in the same buffer. In other words, the slice gets rotated so that old objects can get reused. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	12 months 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

beorn7	aa82fe198f	tsdb: Fix histogram validation So far, `ValidateHistogram` would not detect if the count did not include the count in the zero bucket. This commit fixes the problem and updates all the tests that have been undetected offenders so far. Note that this problem would only ever create false negatives, so we never falsely rejected to store a histogram because of it. On the other hand, `ValidateFloatHistogram` has been to strict with the count being at least as large as the sum of the counts in all the buckets. Float precision issues could create false positives here, see products of PromQL evaluations, it's actually quite hard to put an upper limit no the floating point imprecision. Users could produce the weirdest expressions, maxing out float precision problems. Therefore, this commit simply removes that particular check from `ValidateFloatHistogram`.
