György Krajcsovits	44ebbb8458	Fix missing histogram copy in sampleRing The specialized version of sample add to the ring: func addH(s hSample, buf []hSample, r sampleRing) []hSample func addFH(s fhSample, buf []fhSample, r sampleRing) []fhSample already correctly copy histogram samples from the reused hReader, fhReader buffers, but the generic version does not. This means that the data is overwritten on the next read if the sample ring has seen histogram and float samples at the same time and switched to generic mode. The `genericAdd` function (which was commented anyway) is by now quite different from the specialized functions so that this commit deletes it.

Oleg Zaytsev	e196b977af	Process MemPostings.Delete() with GOMAXPROCS workers We are still seeing lock contention on MemPostings.mtx, and MemPostings.Delete() is by far the most expensive operation on that mutex. This adds parallelism to that method, trying to reduce the amount of time we spend with the mutex held. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	2 months ago

Bryan Boreham	a8133f3e87	TSDB: Simplify benchmark regexps Several regexps were coded like `"^.*$"`, which is an unnatural formulation nobody is likely to use.

Joshua Hesketh	f2064c7987	NH: Do not re-use spans between histograms (#14771 ) promql, tsdb (histograms): Do not re-use spans between histograms When multiple points exist with the same native histogram schemas they share their spans. This causes a problem when a native histogram (NH) schema is modified (for example, during a Sum) then the other NH's with the same spans are also modified. As such, we should create a new Span for each NH. This will ensure NH's interfaces are safe to use without considering the effect on other histograms. At the moment this doesn't present itself as a problem because in all aggregations and functions operating on native histograms they are copied by the promql query engine first.

Bryan Boreham	cde42f30e9	TSDB: streamline reading of overlapping head chunks `getOOOSeriesChunks` was already finding sets of overlapping chunks; we store those in a `multiMeta` struct so that `ChunkOrIterable` can reconstruct an `Iterable` easily and predictably. We no longer need a `MergeOOO` flag to indicate that this Meta should be merged with other ones; this is explicit in the `multiMeta` structure. We also no longer need `chunkMetaAndChunkDiskMapperRef`. Add `wrapOOOHeadChunk` to defeat `chunkenc.Pool` - chunks are reset during compaction, but if we wrap them (like `safeHeadChunk` was doing then this is skipped) .
