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	5b53aa1108	style: Replace `else if` cascades with `switch` ... Wiser coders than myself have come to the conclusion that a `switch` statement is almost always superior to a statement that includes any `else if`. The exceptions that I have found in our codebase are just these two: * The `if else` is followed by an additional statement before the next condition (separated by a `;`). * The whole thing is within a `for` loop and `break` statements are used. In this case, using `switch` would require tagging the `for` loop, which probably tips the balance. Why are `switch` statements more readable? For one, fewer curly braces. But more importantly, the conditions all have the same alignment, so the whole thing follows the natural flow of going down a list of conditions. With `else if`, in contrast, all conditions but the first are "hidden" behind `} else if `, harder to spot and (for no good reason) presented differently from the first condition. I'm sure the aforemention wise coders can list even more reasons. In any case, I like it so much that I have found myself recommending it in code reviews. I would like to make it a habit in our code base, without making it a hard requirement that we would test on the CI. But for that, there has to be a role model, so this commit eliminates all `if else` occurrences, unless it is autogenerated code or fits one of the exceptions above.

Jesus Vazquez	775d90d5f8	TSDB: Rename wal package to wlog (#11352) ... The wlog.WL type can now be used to create a Write Ahead Log or a Write Behind Log. Before the prefix for wbl metrics was 'prometheus_tsdb_out_of_order_wal_' and has been replaced with 'prometheus_tsdb_out_of_order_wbl_'.
