György Krajcsovits	eafe72a0d0	perf(nhcb): optimize away most allocations in convertnhcb In general aim for the happy case when the exposer lists the buckets in ascending order. Use Compact(2) to compact the result of nhcb convert. This is more in line with how client_golang optimizes spans vs buckets. `aef8aedb4b/prometheus/histogram.go (L1485)` Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	4 weeks ago
TJ Hoplock	4f9e4dc016	ref: remove unused deduper log wrapper methods I used these wrapper methods during initial development of the custom handler that the deduper now implements. Since the deduper implements slog.Handler and can be used directly as a logger, these wrapper methods are no longer needed. Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	1 month ago
TJ Hoplock	b602393473	fix: avoid data race in log deduper This change should have been included in the initial prometheus slog conversion, but I must've lost track of it in all the rebases involved in that PR. This changes the dedupe logger so that the only method that needs to use the lock is the `Handle()` method that actually interacts with the deduplication map.

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

beorn7	0f760f63dd	lint: Revamp our linting rules, mostly around doc comments Several things done here: - Set `max-issues-per-linter` to 0 so that we actually see all linter warnings and not just 50 per linter. (As we also set `max-same-issues` to 0, I assume this was the intention from the beginning.) - Stop using the golangci-lint default excludes (by setting `exclude-use-default: false`. Those are too generous and don't match our style conventions. (I have re-added some of the excludes explicitly in this commit. See below.) - Re-add the `errcheck` exclusion we have used so far via the defaults. - Exclude the signature requirement `govet` has for `Seek` methods because we use non-standard `Seek` methods a lot. (But we keep other requirements, while the default excludes completely disabled the check for common method segnatures.) - Exclude warnings about missing doc comments on exported symbols. (We used to be pretty adamant about doc comments, but stopped that at some point in the past. By now, we have about 500 missing doc comments. We may consider reintroducing this check, but that's outside of the scope of this commit. The default excludes of golangci-lint essentially ignore doc comments completely.) - By stop using the default excludes, we now get warnings back on malformed doc comments. That's the most impactful change in this commit. It does not enforce doc comments (again), but _if_ there is a doc comment, it has to have the recommended form. (Most of the changes in this commit are fixing this form.) - Improve wording/spelling of some comments in .golangci.yml, and remove an outdated comment. - Leave `package-comments` inactive, but add a TODO asking if we should change that. - Add a new sub-linter `comment-spacings` (and fix corresponding comments), which avoids missing spaces after the leading `//`.

Łukasz Mierzwa	5597020a60	Use github.com/klauspost/compress for gzip and zlib klauspost/compress is a high quality drop-in replacement for common Go compression libraries. Since Prometheus sends out a lot of HTTP requests that often return compressed output having improved compression libraries helps to save cpu & memory resources.
