György Krajcsovits	c6618729c9	Fix HistogramAppender.Appendable array out of bound error The code did not handle spans with 0 length properly. Spans with length zero are now skipped in the comparison. Span index check not done against length-1, since length is a unit32, thus subtracting 1 leads to 2^32, not -1. Fixes and unit tests for both integer and float histograms added.

Robert Fratto	9e4e2a4a51	wlog: use filepath for getting checkpoint number This changes usage of path to be replaced with path/filepath, allowing for filepath.Base to properly return the base directory on systems where `/` is not the standard path separator. This resolves an issue on Windows where intermediate folders containing a `.` were incorrectly considered to be a part of the checkpoint name. Related to grafana/agent#3826.

Bryan Boreham	0ab9553611	tsdb: drop deleted series from the WAL sooner (#12297 ) `head.deleted` holds the WAL segment in use at the time each series was removed from the head. At the end of `truncateWAL()` we will delete all segments up to `last`, so we can drop any series that were last seen in a segment at or before that point.

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.

beorn7	c3c7d44d84	lint: Adjust to the lint warnings raised by current versions of golint-ci We haven't updated golint-ci in our CI yet, but this commit prepares for that. There are a lot of new warnings, and it is mostly because the "revive" linter got updated. I agree with most of the new warnings, mostly around not naming unused function parameters (although it is justified in some cases for documentation purposes – while things like mocks are a good example where not naming the parameter is clearer). I'm pretty upset about the "empty block" warning to include `for` loops. It's such a common pattern to do something in the head of the `for` loop and then have an empty block. There is still an open issue about this: https://github.com/mgechev/revive/issues/810 I have disabled "revive" altogether in files where empty blocks are used excessively, and I have made the effort to add individual `// nolint:revive` where empty blocks are used just once or twice. It's borderline noisy, though, but let's go with it for now. I should mention that none of the "empty block" warnings for `for` loop bodies were legitimate.

beorn7	817a2396cb	Name float values as "floats", not as "values" In the past, every sample value was a float, so it was fine to call a variable holding such a float "value" or "sample". With native histograms, a sample might have a histogram value. And a histogram value is still a value. Calling a float value just "value" or "sample" or "V" is therefore misleading. Over the last few commits, I already renamed many variables, but this cleans up a few more places where the changes are more invasive. Note that we do not to attempt naming in the JSON APIs or in the protobufs. That would be quite a disruption. However, internally, we can call variables as we want, and we should go with the option of avoiding misunderstandings. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
beorn7	630bcb494b	storage: Use separate sample types for histogram vs. float Previously, we had one “polymorphous” `sample` type in the `storage` package. This commit breaks it up into `fSample`, `hSample`, and `fhSample`, each still implementing the `tsdbutil.Sample` interface. This reduces allocations in `sampleRing.Add` but inflicts the penalty of the interface wrapper, which makes things worse in total. This commit therefore just demonstrates the step taken. The next commit will tackle the interface overhead problem. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

Oleg Zaytsev	6e2905a4d4	Use zeropool.Pool to workaround SA6002 (#12189 ) * Use zeropool.Pool to workaround SA6002 I built a tiny library called https://github.com/colega/zeropool to workaround the SA6002 staticheck issue. While searching for the references of that SA6002 staticheck issues on Github first results was Prometheus itself, with quite a lot of ignores of it. This changes the usages of `sync.Pool` to `zeropool.Pool[T]` where a pointer is not available. Also added a benchmark for HeadAppender Append/Commit when series already exist, which is one of the most usual cases IMO, as I didn't find any.

Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
