newtonne	88675710f9	Add support for utf8 names on /v1/label/:name/values endpoint ... Previously, the api was evaluating this regex to determine if the label name was valid or not: 14bac55a99/model/labels.go (L94) However, I believe that the `IsValid()` function is what ought to be used in the brave new utf8 era. **Before** ``` $ curl localhost:9090/api/v1/label/host.name/values {"status":"error","errorType":"bad_data","error":"invalid label name: \"host.name\""} ``` **After** ``` $ curl localhost:9090/api/v1/label/host.name/values {"status":"success","data":["localhost"]} ``` It's very likely that I'm missing something here or you were already planning to do this at some point but I just encountered this issue and figured I'd give it a go.

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>	2024-11-23 14:20:37 -05:00
beorn7	4b573e0521	promql: Fix subqueries to be really left-open ... Previously, we managed to get rid of the sample on the left bound later, so the problem didn't show up in the framework tests. But the subqueries were still evaluation with the sample on the left bound, taking space and showing up if returning the subquery result directly (without further processing through PromQL like in all the framework tests).

Björn Rabenstein	125a90899c	promqltest: Complete the tests for info annotations (#15429) ... promqltest: Complete the tests for info annotations So far, we did not test for the _absence_ of an info annotation (because many tests triggered info annotations, which we haven't taken into account so far). The test for info annotations was also missed for range queries. This completes the tests for info annotations (and refactors the many `if` statements into a somewhat more compact `switch` statement). It fixes most tests to not emit an info annotation anymore. Or it changes the `eval` to `eval_info` where we actually want to test for the info annotation. It also fixes a few spelling errors in comments. --------- Signed-off-by: beorn7 <beorn@grafana.com> Signed-off-by: Björn Rabenstein <github@rabenste.in> Co-authored-by: Arve Knudsen <arve.knudsen@gmail.com>	2024-11-21 14:20:38 +01:00
