Filip Petkovski	3e6155e596	Use CopyTo when resetting histogram in stats iterator ... The histogram stats iterator does not fully clear the histogram object and is not resilient to new fields being added to the histogram type. To resolve the issue, the commit uses the CopyTo methods which should be future proof to new fields being added. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	4 months ago

Filip Petkovski	be7a4c9b83	Ignore stale histograms for counter reset detection ... The histogram stats decoder keeps track of the last seen histogram sample in order to properly detect counter resets. We are seeing an issue where a histogram with UnknownResetHint gets treated as a counter reset when it follows a stale histogram sample. I believe that this is incorrect since stale samples should be completely ignored in PromQL. As a result, they should not be stored in the histogram stats iterator and the counter reset detection needs to be done against the last non-stale sample.

Filip Petkovski	cb8b6d7504	Allow built-in tests to be customized ... The RunBuiltinTests function accepts a concrete type which makes it hard to exclude certain tests from the suite. It would be great if we could skip tests which might not be critical in order to unblock updates. By accepting an interface instead, we can inject a custom implementation which would skips select test cases. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	5 months ago
beorn7	cff0429b1a	promql: make avg_over_time faster and more precise ... Same idea as for the avg aggregator before: Most of the time, there is no overflow, so we don't have to revert to the more expensive and less precise incremental calculation of the mean value. Signed-off-by: beorn7 <beorn@grafana.com>	5 months ago
beorn7	3a908d8e08	promql: Improve Kahan usage in avg_over_time ... The calculation of the mean value in avg_over_time is performed in an incremental fashion. This introduces additional numerical errors that even Kahan summation cannot compensate, but at least we can use the Kahan-corrected mean value when we use the intermediate mean value in the calculation. Signed-off-by: beorn7 <beorn@grafana.com>	5 months ago
beorn7	c46074f4dd	promql: make avg aggregation more precise and less expensive ... The basic idea here is that the previous code was always doing incremental calculation of the mean value, which is more costly and can be less precise. It protects against overflows, but in most cases, an overflow doesn't happen anyway. The other idea applied here is to expand on #14074, where Kahan summation was applied to sum(). With this commit, the average is calculated in a conventional way (adding everything up and divide in the end) as long as the sum isn't overflowing float64. This is combined with Kahan summation so that the avg aggregation, in most cases, is really equivalent to the sum aggregation with a following division (which is the user's expectation as avg is supposed to be syntactic sugar for sum with a following divison). If the sum hits ±Inf, the calculation reverts to incremental calculation of the mean value. Kahan summation is also applied here, although it cannot fully compensate for the numerical errors introduced by the incremental mean calculation. (The tests added in this commit would fail if incremental mean calculation was always used.) Signed-off-by: beorn7 <beorn@grafana.com>	5 months ago

Filip Petkovski	acb6c1ae4b	Fix decoding buckets for native histograms in binops ... The optimizer which detects cases where histogram buckets can be skipped does not take into account binary expressions.

Oleg Zaytsev	4b7a44c7a0	Fix `parser.VectorSelector.String()` with empty name matcher (#14015) ... The check fell into "this matcher equals vector selector's name" case when vector selector doesn't have a name and the matcher is an explicit matcher for an empty __name__ label. To provide some context about why this is important: some downstream projects use the promql.Parse(expr.String()) to clone an expression's AST, and with this bug that matcher disappears in the cloning.
