Gregor Zeitlinger	f01718262a	Unit tests for native histograms (#12668 ) promql: Extend testing framework to support native histograms This includes both the internal testing framework as well as the rules unit test feature of promtool. This also adds a bunch of basic tests. Many of the code level tests can now be converted to tests within the framework, and more tests can be added easily. --------- Signed-off-by: Harold Dost <h.dost@criteo.com> Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com> Signed-off-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Harold Dost <h.dost@criteo.com> Co-authored-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>	1 year ago
Julius Volz	531567d46e	Drop metric name for "atan2" binary operator The operator changes the meaning of the metric, so the metric name should be dropped. Technically this would be a breaking change, but it's also very obviously a bug and not likely that anyone depends on it. Signed-off-by: Julius Volz <julius.volz@gmail.com>	1 year ago

Ganesh Vernekar	9199fcb8d1	'@ <timestamp>' modifier (#8121 ) This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit. An example query: ``` rate(process_cpu_seconds_total[1m]) and topk(7, rate(process_cpu_seconds_total[1h] @ 1234)) ``` which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.

David King	6286c10df0	Fix OOM when a large K is used in topk queries (#4087 ) This attempts to close #3973. Handles cases where the length of the input vector to an aggregate topk / bottomk function is less than the K paramater. The change updates Prometheus to allocate a result vector the same length as the input vector in these cases. Previously Prometheus would out-of-memory panic for large K values. This change makes that unlikely unless the size of the input vector is equally large. Signed-off-by: David King <dave@davbo.org>	7 years ago
