Tobias Guggenmos	2aacd807b3	PromQL: Various small improvements in the parser (#6652 ) * Move check for empty VectorSelector to typeChecking * Move check for twice set metric name to typeChecking * Make child of MatrixSelector a general Node * rename checkType to checkAST * Rename fail to addParseErr * Remove trailing whitespace Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>	5 years ago

Julien Pivotto	577e738986	Cleanup PromQL functions (#6551 ) * Cleanup PromQL functions The engine ensures, for Matrix functions, that functions are called with exactly one series at the time. Therefore a lot of code can be inlined and we can directly assume the first element of the arguments exists and contains all the samples needed.

Tobias Guggenmos	cd39ebe7c6	PromQL: export function list (#6434 ) This PR exports the list of supported PromQL functions and their signatures. The reason for that is that the PromQL language server likes to use that list. Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>	5 years ago
Tariq Ibrahim	8fdfa8abea	refine error handling in prometheus (#5388 ) i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors. ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives. iii) Does away with the use of fmt package for errors in favour of pkg/errors Signed-off-by: tariqibrahim <tariq181290@gmail.com>	6 years ago

Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Add range-aware support for range vector functions with params Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Optimise holt_winters, cut cpu and allocs by ~25% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make rate&friends range aware Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make more functions range aware.

To protect against subsequent steps in a range query being affected by the previous steps, add a test that evaluates an instant query that we know works again as a range query with the tiimestamp we care about not being the first step. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Reuse ring for matrix iters. Put query results back in pool.

This saves both the calculations and allocs done by dropMetricName across steps. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Reuse input vectors in rangewrapper Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Reuse the point slices in the matrixes input/output by rangeWrapper Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Make benchmark setup faster using AddFast Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> * Simplify benchmark code.

Brian Brazil	4c8173acac	Use timestamp of a sample in deriv() to avoid FP issues (#2958 ) With the squaring of the timestamp, we run into the limitations of the 53bit mantissa for a 64bit float. By subtracting away a timestamp of one of the samples (which is how the intercept is used) we avoid this issue in practice as it's unlikely that it is used over a very long time range.
