Linas Medžiūnas	44df626620	promql (histograms): reconcile mismatched NHCB bounds (#17278 ) Fixes #17255. The implementation happens mostly in the Add and Sub method, but the reconciliation works for all relevant operations. For example, you can now `rate` over a range wherein the custom bucket boundaries are changing. Any custom bucket reconciliation is flagged with an info-level annotation. --------- Signed-off-by: Linas Medziunas <linas.medziunas@gmail.com> Signed-off-by: Linas Medžiūnas <linasm@users.noreply.github.com>	3 months ago

beorn7	71c21fb9e4	Fix minor issues after applying analyzer "modernize" - The tool left an empty line behind that we don't need anymore, see https://github.com/prometheus/prometheus/pull/17092. (Arguably not a bug in the tool but just our stricter style about empty lines.) - In tsdb/index/postings_test.go , our (admittedly somewhat convoluted) code structure tricked the tool so it spit out something that wouldn't even compile. - storage/remote/queue_manager_test.go is just a minor formatting nit.

beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

frazou	9b4c8f6be2	rulefmt: support YAML aliases for Alert/Record/Expr (#14957 ) * rulefmt: add tests with YAML aliases for Alert/Record/Expr Altough somewhat discouraged in favour of using proper configuration management tools to generate full YAML, it can still be useful in some situations to use YAML anchors/aliases in rules. The current implementation is however confusing: aliases will work everywhere except on the alert/record name and expr This first commit adds (failing) tests to illustrate the issue, the next one fixes it. The YAML test file is intentionally filled with anchors and aliases. Although this is probably not representative of a real-world use case (which would have less of them), it errs on the safer side. Signed-off-by: François HORTA <fhorta@scaleway.com> * rulefmt: support YAML aliases for Alert/Record/Expr This fixes the use of YAML aliases in alert/recording rule names and expressions. A side effect of this change is that the RuleNode YAML type is no longer propagated deeper in the codebase, instead the generic Rule type can now be used.

Giedrius Statkevičius	92218ecb9b	promtool: add --ignore-unknown-fields Add --ignore-unknown-fields that ignores unknown fields in rule group files. There are lots of tools in the ecosystem that "like" to extend the rule group file structure but they are currently unreadable by promtool if there's anything extra. The purpose of this flag is so that we could use the "vanilla" promtool instead of rolling our own.

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>	1 year ago
