Jorge Creixell	e9e3d64b7c	PromQL engine: Delay deletion of __name__ label to the end of the query evaluation (#14477 ) PromQL engine: Delay deletion of __name__ label to the end of the query evaluation - This change allows optionally preserving the `__name__` label via the `label_replace` and `label_join` functions, and helps prevent the dreaded "vector cannot contain metrics with the same labelset" error. - The implementation extends the `Series` and `Sample` structs with a boolean flag indicating whether the `__name__` label should be deleted at the end of the query evaluation. - The `label_replace` and `label_join` functions can still access the value of the `__name__` label, even if it has been previously marked for deletion. If `__name__` is used as target label, it won't be dropped at the end of the query evaluation. - Fixes https://github.com/prometheus/prometheus/issues/11397 - See https://github.com/jcreixell/prometheus/pull/2 for previous discussion, including the decision to create this PR and benchmark it before considering other alternatives (like refactoring `labels.Labels`). - See https://github.com/jcreixell/prometheus/pull/1 for an alternative implementation using a special label instead of boolean flags. - Note: a feature flag `promql-delayed-name-removal` has been added as it changes the behavior of some "weird" queries (see https://github.com/prometheus/prometheus/issues/11397#issuecomment-1451998792) Example (this always fails, as `__name__` is being dropped by `count_over_time`): ``` count_over_time({__name__!=""}[1m]) => Error executing query: vector cannot contain metrics with the same labelset ``` Before: ``` label_replace(count_over_time({__name__!=""}[1m]), "__name__", "count_$1", "__name__", "(.+)") => Error executing query: vector cannot contain metrics with the same labelset ``` After: ``` label_replace(count_over_time({__name__!=""}[1m]), "__name__", "count_$1", "__name__", "(.+)") => count_go_gc_cycles_automatic_gc_cycles_total{instance="localhost:9090", job="prometheus"} 1 count_go_gc_cycles_forced_gc_cycles_total{instance="localhost:9090", job="prometheus"} 1 ... ``` Signed-off-by: Jorge Creixell <jcreixell@gmail.com> --------- Signed-off-by: Jorge Creixell <jcreixell@gmail.com> Signed-off-by: Björn Rabenstein <github@rabenste.in>	3 months ago

Bryan Boreham	cde42f30e9	TSDB: streamline reading of overlapping head chunks `getOOOSeriesChunks` was already finding sets of overlapping chunks; we store those in a `multiMeta` struct so that `ChunkOrIterable` can reconstruct an `Iterable` easily and predictably. We no longer need a `MergeOOO` flag to indicate that this Meta should be merged with other ones; this is explicit in the `multiMeta` structure. We also no longer need `chunkMetaAndChunkDiskMapperRef`. Add `wrapOOOHeadChunk` to defeat `chunkenc.Pool` - chunks are reset during compaction, but if we wrap them (like `safeHeadChunk` was doing then this is skipped) .

György Krajcsovits	41c076196e	New cases in Test_ChunkQuerier_OOOQuery and Test_Querier_OOOQuery Case 1: OOO in-memory head chunk overlaps with first mmaped in-order chunk. Query: \|----------------------------------------------------------------\| InO: \|------mmap---------------\|\|---------mem----------------------\| OOO: \|-----mem-----------\| This triggers ChunkOrIterableWithCopy not including OOO head chunks bug. Similar to #14693 however testing the end of the interval doesn't trigger the problem because there the in-order head chunk will be trimmed with a tombstone, causing the code to switch to ChunkOrIterable which was fixed. See `a36d1a8a92/tsdb/querier.go (L646)` where len(p.bufIter.Intervals) will be non zero, because it includes the tombstone to trim the result to the query max time. Thus a new test is added to check the overlap at the beginning of the interval that has a separate chunk, which does not need trimming. Note: same test doesn't fail for sample querier in Test_Querier_OOOQuery as that doesn't use copy, that is copyHeadChunk is false in the if condition above. Case 2: OOO mmaped head chunk overlaps with first mmaped in-order chunk. Query: \|----------------------------------------------------------------\| InO: \|------mmap---------------\|\|---------mem----------------------\| OOO: \|-----mmap-----------\| \|--mem--\| In this case the meta contains the reference of the in-order chunk and no indication that a merge is needed with the OOO mmaped chunk.

Björn Rabenstein	5fd2717aec	Merge pull request #14715 from prometheus/beorn7/lint lint: Revamp our linting rules, mostly around doc comments	3 months 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 `//`.

Bryan Boreham	9a74d53935	[BUGFIX] TSDB: Fix query overlapping in-order and ooo head (#14693 ) * tsdb: Unit test query overlapping in order and ooo head Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * TSDB: Merge overlapping head chunk The basic idea is that getOOOSeriesChunks can populate Meta.Chunk, but since it only returns one Meta per overlapping time-slot, that pointer may end up in a Meta with a head-chunk ID. So we need HeadAndOOOChunkReader.ChunkOrIterable() to call mergedChunks in that case. Previously, mergedChunks was checking that meta.Ref was a valid OOO chunk reference, but it never actually uses that reference; it just finds all chunks overlapping in time. So we can delete that code. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> Co-authored-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	3 months ago
