Oleg Zaytsev	b1e4052682	MemPostings.Delete(): make pauses to unlock and let the readers read (#15242 ) This introduces back some unlocking that was removed in #13286 but in a more balanced way, as suggested by @pracucci. For TSDBs with a lot of churn, Delete() can take a couple of seconds, and while it's holding the mutex, reads and writes are blocked waiting for that mutex, increasing the number of connections handled and memory usage. This implementation pauses every 4K labels processed (note that also compared to #13286 we're not processing all the label-values anymore, but only the affected ones, because of #14307), makes sure that it's possible to get the read lock, and waits for a few milliseconds more.

György Krajcsovits	bb70370d72	TSDB head: fix race between AppendHistogram and Commit Move writing memSeries lastHistogramValue and lastFloatHistogramValue after series creation under lock. The resulting code isn't totally correct in the sense that we're setting these values before Commit() , so they might be overwritten/rolled back later. Also Append of stale sample checks the values without lock, so there's still a potential race. The correct solution would be to set these only in Commit() which we actually do, but then Commit() would also need to process samples in order and not floats first, then histograms, then float histograms - which leads to not knowing what stale marker to write for histograms.

TJ Hoplock	6ebfbd2d54	chore!: adopt log/slog, remove go-kit/log For: #14355 This commit updates Prometheus to adopt stdlib's log/slog package in favor of go-kit/log. As part of converting to use slog, several other related changes are required to get prometheus working, including: - removed unused logging util func `RateLimit()` - forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger - move some of the json file logging functionality to use prom/common package functionality - refactored some of the new json file logging for scraping - changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers - updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition - added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	2 months ago
Bryan Boreham	91de19fbef	[BUGFIX] TSDB: Don't read in-order chunks from before head MinTime Because we are reimplementing the `IndexReader` to fetch in-order and out-of-order chunks together, we must reproduce the behaviour of `Head.indexRange()`, which floors the minimum time queried at `head.MinTime()`.

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.
