TJ Hoplock	437362a7a7	fix(deduper): use ptr to sync.RWMutex, fix panic during concurrent use Resolves: #15559 As accurately noted in the issue description, the map is shared among child loggers that get created when `WithAttr()`/`WithGroup()` are called on the underlying handler, which happens via `log.With()` and `log.WithGroup()` respectively. The RW mutex was a value in the previous implementation that used go-kit/log, and I should've updated it to use a pointer when I converted the deduper. Also adds a test.

TJ Hoplock	e0104a6b7e	ref: JSONFileLogger slog handler, add scrape.FailureLogger interface Improves upon #15434, better resolves #15433. This commit introduces a few changes to ensure safer handling of the JSONFileLogger: - the JSONFileLogger struct now implements the slog.Handler interface, so it can directly be used to create slog Loggers. This pattern more closely aligns with upstream slog usage (which is generally based around handlers), as well as making it clear that devs are creating a whole new logger when interacting with it (vs silently modifying internal configs like it did previously). - updates the `promql.QueryLogger` interface to be a union of the methods of both the `io.Closer` interface and the `slog.Handler` interface. This allows for plugging in/using slog-compatible loggers other than the JSONFileLogger, if desired (ie, for downstream projects). - introduces new `scrape.FailureLogger` interface; just like `promql.QueryLogger`, it is a union of `io.Closer` and `slog.Handler` interfaces. Similar logic applies to reasoning. - updates tests where needed; have the `FakeQueryLogger` from promql's engine_test implement the `slog.Handler`, improve JSONFileLogger test suite, etc. Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	1 year ago

TJ Hoplock	3e24e84172	fix!: stop unbounded memory usage from query log Resolves: #15433 When I converted prometheus to use slog in #14906, I update both the `QueryLogger` interface, as well as how the log calls to the `QueryLogger` were built up in `promql.Engine.exec()`. The backing logger for the `QueryLogger` in the engine is a `util/logging.JSONFileLogger`, and it's implementation of the `With()` method updates the logger the logger in place with the new keyvals added onto the underlying slog.Logger, which means they get inherited onto everything after. All subsequent calls to `With()`, even in later queries, would continue to then append on more and more keyvals for the various params and fields built up in the logger. In turn, this causes unbounded growth of the logger, leading to increased memory usage, and in at least one report was the likely cause of an OOM kill. More information can be found in the issue and the linked slack thread. This commit does a few things: - It was referenced in feedback in #14906 that it would've been better to not change the `QueryLogger` interface if possible, this PR proposes changes that bring it closer to alignment with the pre-3.0 `QueryLogger` interface contract - reverts `promql.Engine.exec()`'s usage of the query logger to the pattern of building up an array of args to pass at once to the end log call. Avoiding the repetitious calls to `.With()` are what resolve the issue with the logger growth/memory usage. - updates the scrape failure logger to use the update `QueryLogger` methods in the contract. - updates tests accordingly - cleans up unused methods Builds and passes tests successfully. Tested locally and confirmed I could no longer reproduce the issue/it resolved the issue. Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	1 year 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.

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

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 `//`.
